Description

A pin-type writing and counting dual-purpose pen

technical field

The invention relates to the field of stationery, in particular to a dual-purpose pen integrating writing and counting.

Background technique

At present, the pens seen on the market include pencils, ballpoint pens, fountain pens, watercolor pens, etc., whose main function is writing, and the function is relatively simple; and someone invented the counting pen, which realized the counting function of the pen, but lost the original pen at the same time. normal writing function.

Contents of the invention

The invention provides a dual-purpose pen for writing and counting, which is reformed from the existing pin-type ballpoint pen, and a counter is installed inside it. In addition to the original writing function, it also has a counting function. Implement cumulative counting. After adding the counting function, the normal writing function of the pen is not lost, and the two can be switched freely without affecting each other.

Before explaining the technical scheme of the present invention, let us first understand the working process (seeing Fig. 1 to Fig. 4) of the retractable nib of the ejector type ballpoint pen. The top pin type telescopic mechanism is housed in the top pin type ballpoint pen pen holder, and this mechanism is made up of runner A (3), runner B (2), vertical guide rail (1) and spring (4). Among them, the runner A (3) is connected with the button (5) on the top of the pen holder, the runner B (2) is located under the runner A (3) and connected with the refill (6), and the vertical guide rail (1) is located on the penholder ( 7) The inner wall is opposite to the position of the runner A (3) and the runner B (2). The outer wall of the runner A (3) and the runner B (2) has grooves and is stuck in the vertical guide rail (1). It can move up and down along the vertical guide rail (1), and there is a peripheral helical tooth structure between the runner A (3) and the runner B (2). The spring (4) is sleeved on the pen core (6), and is located between the front end opening of the pen holder (7) and the front section of the pen core (6). When in use, press the button (5) on the top of the penholder with your hand to make the two runners A(3) and B(2) in the penholder slide relative to each other along the vertical guide rail (1) under the action of the axial force. When B(2) moves out of the vertical guide rail (1), under the action of the peripheral helical teeth, the runner B(2) rotates relative to the runner A(3) and the vertical guide rail (1), so that the helical teeth The notch is facing the end of the vertical guide rail (1), and at this moment, the outward stretching distance of the nib reaches the maximum value. When the force of the finger pressing the button (5) on the top of the pen holder disappears, under the force of the rebound of the spring (4), the pen core (6) moves inward, the pen head shrinks inward, and the runners A (3) and B (2) also move inward. Since the notch of the helical tooth of B(2) is just facing the end of the vertical guide rail (1), after moving in a short distance, the notch of the helical tooth of B(2) is just embedded in the end of the vertical guide rail (1). That is to say, the runner B (2) is embedded in the end of the vertical guide rail (1), so that the position of the pen core (6) can no longer be moved inwardly, and its position is fixed. It is still stretched out, which is the best writing state of the pen. When the ballpoint pen is used up and the tip of the pen needs to be retracted, press the button (5) on the top of the pen barrel again with your hand, push the runner A (3) to slide down along the vertical guide rail (1), touch the runner B (2) and press it again When it is pushed out of the vertical guide rail (1), under the action of the peripheral helical teeth, the runner B (2) rotates relative to the runner A (3) and the vertical guide rail (1). After the wheel B (2) rotates an angle, the groove of the wheel B (2) is facing the vertical guide rail (1) on the pen container and snapped into it again, under the elastic force of the spring (4), the wheel B ( 2) The runner A (3) slides up to the top along the vertical guide rail (1), and the position of the pen core (6) also moves up accordingly, and the pen head retracts.

in conclusion:

1. The function of the vertical guide rail (1) is to restrain the rotation of the runner A (3) and the runner B (2), so that they can only move up and down; when the runner B (2) moves down to break away from the vertical Just can rotate automatically during straight guide rail (1), and the reason of rotation is because between two runners A (3), B (2) peripheral helical teeth, due to the effect of the rotational force that mutual mechanical structure produces.

2. Due to the limited length of the button (5) on the top of the pen holder, no matter how you press it with your fingers, the runner A (3) cannot move down enough distance to break away from the vertical guide rail (1), so the runner A (3) can only move up and down. Equivalent to a slider;

3. Because the wheel B (2) is under the wheel A (3), when the finger presses the button (5) on the top of the pen holder, it can move down along the vertical guide rail (1) and can break away from the vertical guide rail (1). When it just breaks away from the vertical guide rail (1), due to the mechanical action between the peripheral helical teeth of the runners A(3) and B(2), the runner B(2) rotates so that the notch of the helical teeth faces the vertical guide rail (1) End. When the force of pressing the button (5) on the top of the pen holder disappears, under the force of the rebound of the spring (4), the runner B (2) retracts for a short distance, and then its helical notch is stuck on the vertical guide rail ( 1) At the end, the position does not move anymore. At the same time, the pen core (7) first moves down to the maximum position, and the nib also stretches out to the maximum distance, then the pen core (7) is partially retracted, and the nib is also partially retracted, and then the position is fixed, and the nib still remains stretched out. state, which is the best writing state of the pen at this time. And when the finger presses the button (5) on the top of the penholder again, the runner B (2) is pushed away from the end of the vertical guide rail (1), due to the gap between the peripheral helical teeth of the runners A (3), B (2) The mechanical action produces rotation, so that the groove of B (2) is facing the vertical guide rail (1), and then, under the elastic force of the spring (4), the runner B (2) slides into the vertical guide rail (1) again and Move up, and now the pen core (7) moves up, and the nib retracts, which is the state that the pen cannot write.

If counter (11) is added on the basis of the above pin-type ball-point pen jack-type telescopic mechanism, make it realize counting function, will keep original normal writing function again simultaneously, also will make both can switch freely, mutually independent Interference is indeed technically very difficult and requires high skills.

The present invention solves the technical problem through the following technical solutions: a dual-purpose pen for writing and counting with pins, which is transformed from the existing ball-point pen with pins, and is characterized in that it has a telescopic mechanism with pins for the existing ball-point pen with pins, which contains The components such as runner A (3), runner B (2), vertical guide rail (1) and spring (4) etc., in addition, the top pin type writing and counting dual-purpose pen adds the unique cap (16), and the cap (16 ) internal rear end is equipped with a counter (11), the count button (12) of the counter (11) is hidden in the pen cap (16), the reset button (13) exposes the end of the pen cap (16), and the pen cap (16) has a corresponding The digital display window (10) is used to display the counting changes of the digital display screen (14) of the counter (11), and the original pen clip (9) at the end of the pen holder (7) of the ejector pin type ballpoint pen displaces the cap (16 )superior.

Pen cap (16) and penholder (7) front end socket adopt former existing mode, promptly plug or screw, and its corresponding structure is buckle or screw thread. However, when writing, the general ballpoint pen can directly put the cap (16) on the end of the pen holder (7), without a corresponding socket structure, and only rely on the close contact between the end of the pen cap (16) and the end of the pen holder (7) to produce a friction sleeve combine together. When the push pin type writing and counting dual-purpose pen of the present invention is counting, the pen cap (16) needs to be sleeved on the end of the pen holder (7), and the counter (11) in the pen cap (16) is placed on the end of the pen holder (7). The position is required to be very precise, and the position cannot be shifted due to the force. Therefore, a special socket structure needs to be added between the inner wall of the pen cap (16) and the end of the pen holder (7). This structure can be threaded or buckled. Effect is to play the effect of positioning counter (11), thereby has corresponding appellation, as counter positioning thread (15) etc. The newly added socket structure at the end of the pen cap (16) and the penholder (7) cannot affect the use of the socket structure at the front end of the original pen cap (16) and the penholder (7). The combination design means that only a kind of socket structure is needed in the pen cap (16), but it can simultaneously play the role of covering the front end of the penholder (7) to protect the nib and being enclosed within the end of the penholder (7) to play a positioning counter ( 11) The role of.

After the counter (11) is accurately positioned, the following effects are achieved: when using the counting function of the push pin type writing and counting dual-purpose pen, first press the button (5) on the top of the pen holder, so that the push pin type writing and counting dual-purpose pen is in a state of being unable to write. When the nib retracts, under the action of the spring (4), the runner B (2), runner A (3) and the top button (5) of the pen holder all move up to the top along the vertical guide rail (1), and then The pen cap (16) is socketed together with the top of the pen holder (7), so that the precise positioning of the counter (11) can be completed. At this time, the count button (12) of the counter (11) in the pen cap (16) will touch the position of the button (5) on the top of the pen holder, and the button (5) on the top of the pen holder will be partially pressed down, and the wheel A (3), wheel B(2) moves down along the vertical guide rail (1), but the moving distance is limited, the wheel B(2) fails to move out of the vertical guide rail (1), and is still inside the vertical guide rail (1), so the result is The tip of the pen is exposed, but the exposed part is slightly less or the same than that in the writing state of the pen. Because runner A (3) and runner B (2) still stay in the vertical guide rail (1) and can slide, the nib can be clicked and counted, and when the nib is clicked, it is retracted under force, causing runner B (2), runner A (3) and the penholder top button (5) move up, and the penholder top button (5) presses the counting button (12), so that the digital display screen (14) of the counter (11) is counted and changed. Because the distance after the counting button (12) of the counter (11) moves inward fails to cause the nib to retract completely, the nib can also have a small part exposed outside the penholder (7), so after the counting action occurs, the nib can still be at the counting place. Make simple counting marks. And when the nib left the click place, the effect of the force generated by the nib click disappeared, and under the effect of the force of the count button (12) rebounding, the button on the top of the penholder (5), the runner A (3), the runner B (2 ) moves down to the original position again, and the nib reappears, waiting for the start of another counting action. When finishing counting, when counter data is reset to zero, as long as press the reset button (13) of pen cap (16) end and get final product. Since the position and moving distance of each part can be properly designed and arranged, it can be ensured that the counting function of the push-pin type writing and counting dual-purpose pen can be realized smoothly.

When switching the top pin type writing and counting dual-purpose pen to the writing state, take off the pen cap (16), and directly press the button (5) on the top of the pen holder with your hands to make the runner A (3) and the runner of the top pin telescopic mechanism The position of B(2) moves down, and the runner B(2) moves out of the vertical guide rail (1) and rotates, and then embedded in the end of the vertical guide rail (1), the nib is exposed, and the position is fixed, and it can be written At this time, the pen cap (16) is socketed with the end of the penholder (7). After socketing, the position of the counting button (12) on the penholder remains unchanged, but the top button (5) of the penholder moves down due to the position of the penholder in the writing state. After a certain distance, the counting button (12) will not press the button (5) on the top of the pen holder, and will not change the ongoing writing state.

The beneficial effect of the present invention is that the counting function is added on the basis of the common ejector pin type ballpoint pen, which avoids the defect that other similar counting pens only have the counting function but cannot realize the normal writing function, and the writing function and the counting function can be switched freely and mutually. It does not affect, it can be said that the idea is unique and the method is ingenious. No matter in structure or function, each part of the top-pin writing and counting dual-purpose pen can naturally become an organic and perfect whole.

The present invention is suitable for use in occasions where counting is required, such as colony counting, counting the number of words read, counting the number of people on the roster, etc., such as the counting of bacterial colonies, which is often involved in many fields such as bioengineering, food production, agricultural production, medical and health, and environmental monitoring. , so the present invention has quite extensive use value.

detailed description

The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Fig. 5 to Fig. 9, a dual-purpose pen for writing and counting of the pin topping type involved in the present invention is transformed from the existing pin topping type ballpoint pen, and is characterized in that it has the pin topping type of the existing pin topping type ballpoint pen. Telescopic structure, the mechanism is composed of runner A (3), runner B (2), vertical guide rail (1) and spring (4), wherein runner A (3) is connected with the button (5) on the top of the pen holder, The runner B (2) is located under the runner A (3) and connected to the refill (6), the vertical guide rail (1) is located on the inner wall of the pen holder (7) and where the runner A (3) and the runner B (2) are located At the relative position, the outer walls of runner A (3) and runner B (2) have grooves and are stuck in the vertical guide rail (1), so that they can move up and down along the vertical guide rail (1). In addition, runner A (3) There is a peripheral helical tooth structure between the runners B (2). The spring (4) is sleeved on the pen core (6), and is located between the front end opening of the pen holder (7) and the front section of the pen core (6). The structure described above is basically the same as the existing top pin type ballpoint pen. What is different from the existing top pin type ballpoint pen is that the top pin type writing and counting dual-purpose pen has a unique cap (16) in addition, and the inner rear end of the cap (16) is installed A counter (11) is arranged, and the counting button (12) of the counter (11) is hidden in the pen cap (16), and the reset button (13) exposes the end of the pen cap (16), and the pen cap (16) has a corresponding digital display window ( 10), in order to display the counting change of the digital display screen (14) of counter (11), the pen clip (9) that is originally positioned on the top pin type ballpoint pen pen holder (7) is transposed on the pen cap (9).

The cap (16) and the front end socket structure of the pen holder (7) adopt the buckle or screw thread mode that is common in existing pens, as shown in Figures 5 to 9, a top pin type writing and counting dual-purpose pen adopts the buckle (17 ) socket.

In order to make the counter (11) in the pen cap (16) accurately and firmly fixed at a certain position at the end of the pen holder (7) when counting, a special counter (11) for precise positioning is added on the inner wall of the pen cap (16) and the end of the pen holder (7). The socket structure of the position can be a threaded or buckle type. A kind of push pin type writing and counting dual-purpose pen as shown in Figure 5 to Figure 9 chooses the threaded way, so this thread is called the counter positioning thread (15 ).

When using the counting function of the push-pin type writing and counting dual-purpose pen, first press the button (5) on the top of the pen holder, so that the push-pin type writing and counting dual-purpose pen is in a non-writing state, that is, the nib is retracted. At this time, the spring (4 ), the runner B (2), runner A (3) and the top button (5) of the pen holder all move up to the top. And when the pen cap (16) is sleeved on the top of the penholder (7) and the counter positioning thread (15) is tightened, the counting button (12) in the pen cover (16) touches the position of the button (5) on the top of the penholder, and the penholder The position of the top button (5) moves down, and the runner A (3) and wheel B (2) move down along the vertical guide rail (1), but the moving distance is limited, and the wheel B (2) cannot move out of the vertical guide rail ( 1), still within the vertical guide rail (1), so the result is that the nib is exposed, but the exposed length is slightly less or the same than that in the writing state of the pen. Because runner A (3) and runner B (2) still stay in the vertical guide rail (1) and can slide, the nib can be clicked and counted, and when the nib is clicked, it is retracted under force, causing runner B (2), runner A (3) and the penholder top button (5) move up, and the penholder top button (5) presses the counting button (12), so that the digital display screen (14) of the counter (11) counts and changes, and when the nib leaves the clicked place , the force generated when clicking disappears, and under the action of the rebound force of the counting button (12), the button (5), runner A (3), and runner B (2) on the top of the pen holder move down to their original positions , the tip of the pen reappears, waiting for the start of the next counting action. When finishing counting, when counter data is reset to zero, as long as press the reset button (13) of pen cap (16) end and get final product. Because the moving position and distance of each of the above components are designed and arranged properly, the counting action of the push-pin type writing and counting dual-purpose pen can be smoothly realized.

And when the top pin type writing and counting dual-purpose pen is switched to the writing state, take off the pen cap (16), directly press the button (5) on the top of the penholder with your hand, the runner A (3) and the runner of the top pin type telescopic mechanism will The position of B(2) moves down, and the runner B(2) moves out of the vertical guide rail (1) and rotates to be embedded in the end of the vertical guide rail (1), the tip of the pen is exposed, and the position is fixed, and it can be written. When the pen cap (16) is socketed with the end of the penholder (7), after the socketing is completed, the position of the counting button (12) on the penholder has not changed, but the runner B (2) has been embedded in the vertical guide rail ( 1) At the end, the positions of the wheel A (3) and the top button (5) of the pen holder have moved down for a certain distance, and the counting button (12) will not press the button (5) on the top of the pen holder, so the writing state in progress cannot be changed , and at this time, if you want to switch to a non-writing state, you can take off the pen cap (16), press the button (5) on the top of the pen holder with your hand, the pen tip can be retracted into the pen, and then put the pen cap (16) on the front end of the pen holder (7) That's it.

The newly added socket structure for positioning the counter (11) at the end of the pen cap (16) and the pen holder (7) as described above cannot affect the use of the front end socket structure of the original pen cap (16) and the pen holder (7). The structure can be independently designed separately (as shown in Figures 5 to 9), and the two can also be integrated into one design, that is to say, only one set of socket structure is needed in the pen cap (16), and the pen holder can be encased at the same time. (7) the effect of front end protection nib and be enclosed within pen holder (7) end and play the effect of positioning counter (11), this point is easy to accomplish in design.

The present invention is suitable for use in various occasions requiring counting, has extensive practical value and relatively high economic value, is exquisite in conception, simple in operation, common in many accessories and other ballpoint pens, and convenient in implementation.
