Detailed Description
The invention is described in detail below with reference to the figures and the embodiments.
The invention provides a fitting suitable for a batch head and a batch head assembly with the fitting. FIG. 1 is a schematic view of a fitting of a first embodiment of the present invention sleeved on a batch head; fig. 2 is a schematic cross-sectional view of the accessory of fig. 1 mounted on the batch head. Referring to fig. 1 and 2, the batch head assembly includes a fitting 100 and a batch head 200, wherein the fitting 100 is sleeved on the batch head 200. The fitting 100 includes: the sleeve 11, the limiting piece 12, the functional piece 13, the mounting sleeve 14 and the end cover 15. For convenience of explanation of the technical solution of the present invention, the following definitions are specifically made: the axis passing through the center of the bit 200 and the fitting 100 is defined as a first axis Y, the directions of the first axis Y and the direction parallel to the first axis Y are axial, the circumferential direction around the first axis Y is a circumferential direction, and the direction perpendicular to the first axis Y and pointing to the first axis Y is a radial direction.
Fig. 3 shows a schematic cross-sectional view of the fitting of fig. 1. Please refer to fig. 1 to fig. 3: the sleeve 11, which is the main bearing part of the fitting 100 of the present invention, has an accommodating cavity 111 formed therein and extending through the sleeve 11, the accommodating cavity 111 extending in the direction of the first axis Y for the passage of the bit 200. In particular, the sleeve 11 is an internal hollow structure extending along an axis and comprising an inner wall and an outer wall, wherein the inner wall surrounds the housing cavity 111 for the batch head 200 to pass through. A stop portion 112 is further formed on the inner wall of the sleeve 11, i.e. the side wall of the accommodating cavity 111, the stop portion 112 takes the first axis Y as a central axis, and the stop portion 112 further forms an annular stop surface 112a, and the stop surface 112a is perpendicular to the first axis Y.
Fig. 4 is a schematic structural diagram of the limiting element in fig. 3; FIG. 5 is a cross-sectional view of a stopper acting on a batch head. Referring to fig. 1 to 4, the limiting member 12 is used to limit the size of the portion of the bit 200 passing through and protruding out of the fitting 100. The limiting member 12 is formed with a limiting hole 121 penetrating the limiting member 12, and the limiting member 12 further includes a first contour portion 122 and a second contour portion 123, wherein the first contour portion 122 is used to form a hole wall at the position where the aperture of the limiting hole 121 is the smallest, and the second contour portion 123 is used to form a hole wall at the position where the aperture of the limiting hole 121 is the largest. The limiting member 12 is located in the accommodating cavity 111 of the sleeve 11, and is installed into the accommodating cavity 111 from one end of the accommodating cavity 111, and the stopping portion 112 in the accommodating cavity 111 can prevent the limiting member 12 from further moving out of the accommodating cavity 111 from the other end, so that the limiting member 12 is installed in the accommodating cavity 111. When the limiting member 12 is located at the installation position stopped by the stopping portion 112, the penetrating direction of the limiting hole 121 is also parallel to the penetrating direction of the accommodating cavity 111, that is, the penetrating direction of the limiting hole 121 is also parallel to the first axis Y direction. In the present invention, the structure of the stopper 12 is described as a reference state when it is located at the installation position, but this is not essential to limit the present invention; in addition, it is further explained about the penetrating direction of the limiting hole 121 and the accommodating cavity 111, if the area surrounded by the limiting hole 121 or the accommodating cavity 111 is regarded as a virtual entity, the central axis direction of the entity refers to the penetrating direction of the limiting hole 121 or the accommodating cavity 111.
Specifically, the thickness of the stopper 12 in the axial direction is approximately 0.1 to 5mm, preferably 1mm, and the thickness thereof is thin. The first contour portion 122 and the second contour portion 123 of the limiting hole 121 are disposed at the same axial position of the limiting hole 121, that is, if the thicknesses of the first contour portion 122 and the second contour portion 123 in the axial direction are neglected, the first contour portion 122 and the second contour portion 123 are located in the same plane, and the plane is perpendicular to the first axis Y direction, so that the first contour portion 122 and the second contour portion 123 at the limiting hole 121 can be regarded as an inner circle of a cross section of the limiting member 12 perpendicular to the first axis Y, and further, an outer circle of the cross section is a circle. At the inner ring, first contour portions 122 and second contour portions 123 are alternately provided in the circumferential direction of the stopper hole 121, and the first contour portions 122 protrude from the second contour portions 123. Wherein the first contour portion 122 includes: the inner arc edge 122a is a circular arc with a first radius, the straight line edges 122b are located on two sides of the inner arc edge 122a, two ends of the inner arc edge 122a are connected to one ends of the two straight line edges 122b located on two sides, one end of each straight line edge 122b is connected with the inner arc edge 122a, and the other end of each straight line edge 122b is connected with the second contour portion 123. The second profile portion 123 includes an outer arc edge 123a, both ends of which are connected to the straight edge 122b, the outer arc edge 123a is a circular arc with a second radius, and the second radius is larger than the first radius, so that the distance from the inner arc edge 122a to the first axis Y is smaller than the distance from the outer arc edge 123a to the first axis Y, and the first profile portion 122 protrudes from the second profile portion 123.
The functional member 13 is provided at one end of the sleeve 11 of the present invention, and different functions of the fitting 100 of the present invention are realized depending on the functional member 13. In this embodiment, in order to tighten the screw with one hand without holding the screw by hand, the functional component 13 is a magnet capable of attracting the screw, the magnet is installed in an open installation groove (not shown) formed at the front end of the sleeve 11, and the magnet is a ring member with magnetic property and hollow inside, so that the magnet can penetrate through the accommodating cavity 111. Thus, when the accessory 100 of the present invention is sleeved on the screwdriver bit 200, when the screwdriver bit 200 is close to the screw, the screw can be attracted by the magnet on the accessory 100 without being held by hand, thereby realizing one-hand operation.
The mounting sleeve 14 is disposed in the accommodating chamber 111, and can move back and forth in the accommodating chamber 111 in the axial direction. The mounting sleeve 14 is made of an elastic material, such as a rubber material, and can be elastically wrapped around the batch head 200. In the present embodiment, the section of the mounting sleeve 14 in the circumferential direction is an annular structure, and the length of the mounting sleeve 14 in the axial direction is between 5mm and 20mm, and the mounting sleeve 14 with a certain length can make the bit 200 and the sleeve 11 parallel to each other. In addition, the mounting sleeve 14 made of elastic material can not only tightly sleeve the mounting sleeve 14 on the batch head 200, but also sleeve more batch heads 200 with different sizes, so that the fitting 100 of the present invention can be suitable for batch heads 200 with more specifications.
In order that the mounting sleeve 14 cannot move out of the receiving space 111 in the axial direction toward the end of the sleeve 11 where the functional element 13 is mounted, the limiting element 12 is located between the stop 112 and the end of the sleeve 11 away from the functional element 13, and the mounting sleeve 14 is disposed between the limiting element 12 and the end of the sleeve 11 away from the functional element 13. Thus, the inside of the sleeve 11, from the functional element 13 to the other end, is: the functional element 13, the stopping portion 112, the limiting element 12 and the mounting sleeve 14, so that the stopping portion 112 can stop the limiting element 12 from moving out of the accommodating cavity 111 from the end of the sleeve 11 where the functional element 13 is mounted, that is, the limiting element 12 cannot move out of the accommodating cavity 111 under the stopping action of the stopping portion 112, and further the mounting sleeve 14 cannot move out of the accommodating cavity 111 even under the limitation of the stopping portion 112 or the limiting element 12.
In order to further prevent the mounting sleeve 14 and the limiting element 12 from moving out of the receiving space 111 in the axial direction towards the end of the sleeve 11 remote from the functional element 13, an end cap 15 is further provided at the other end of the sleeve 11, so that the limiting element 12 and the mounting sleeve 14 are located between the end cap 15 and the stop 112, so that the mounting sleeve 14 can move within a predetermined range. The end cap 15 forms an insertion hole 151, and the batch head 200 enters the accommodating cavity 111 of the sleeve 11 from the insertion hole 151, sequentially passes through the mounting sleeve 14, the limiting member 12, the stopping portion 112 and the functional member 13 until partially passes through the sleeve 11. The end cap 15 includes a cover portion 152 and a connecting portion 153, the cover portion 152 is used for stopping the mounting sleeve 14 from moving out of the accommodating cavity 111, and an insertion hole 151 is formed, and the diameter of the insertion hole 151 is smaller than the outer diameter of the mounting sleeve 14. The connecting portion 153 is used for detachably mounting the end cap 15 on one end of the sleeve 11 away from the functional element 13, the connecting portion 153 is in threaded connection with the sleeve 11, an external thread is arranged on the outer wall of the sleeve 11, and an internal thread (not shown) matched with the external thread is arranged on the connecting portion 153. Of course, it will be understood that the end cap 15 may not include the connecting portion 153 and may be directly formed integrally with the sleeve 11.
Preferably, in order to further ensure the concentricity of the bit 200 with respect to the fitting 100 when the fitting 100 is fitted to the bit 200, in the present embodiment, the end cap 15 is formed with a stopper wall surface 154 extending in parallel to the penetrating direction of the accommodating chamber 111 in the insertion hole 151, and the stopper wall surface 154 forms a portion of the insertion hole 151 having the smallest diameter. In fact, the thickness of the end cap 15 also substantially determines the length of the limiting wall surface 154 along the penetrating direction of the accommodating cavity 111, and therefore, in order to make the length of the limiting wall surface 154 as long as possible, the corresponding thickness of the end cap 15 is also set to be thicker, so that the contact area between the limiting wall surface 154 and the side surface of the bit 200 is larger, and thus, the deviation of the bit 200 from the first axis Y direction relative to the sleeve 100 due to an external force or the magnetic force of the magnet can be avoided, and the concentricity can be further ensured. Specifically, here, the ratio of the aperture diameter of the insertion hole 151 to the length of the stopper wall surface 154 in the penetrating direction of the accommodation chamber 111 is taken as a reference value, and the ratio range is preferably 1.1 or more and 5.5 or less. Further, the length of the stopper wall surface 154 in the penetrating direction of the housing chamber 111 is preferably 2mm or more and 5mn or less.
Preferably, the sleeve 11 is made of aluminum or plastic, so that the magnetism of the magnet and the nail sucking effect are not influenced. In addition, the position limiting member 12 is preferably made of iron, so that the position limiting member 12 has high hardness and is relatively wear-resistant.
Based on the above specific structure of the fitting 100, the functional relationship between the fitting 100 and the batch head 200 is described as follows:
the batch head 200 comprises a head 21, the head 21 is used for acting with a screw, and in order to match with the head shape of the screw, patterns with different shapes, such as a straight line, a cross, a square, a star, a hexagon and the like, are also generally formed on the head 21 of the batch head 200.
Here, take a cross-shaped and non-skinned batch head 200 as an example: the pattern of the head 21 of the cross-shaped batch head 200 includes grooves 211 and protrusions 212, and the grooves 211 and the protrusions 212 are spaced apart.
Referring to fig. 2, 4 and 5, firstly, the batch head 200 is inserted into the accommodating cavity 111 from the insertion hole 151 of the end cover 15, and passes through the mounting sleeve 14, the limiting member 12 and the functional member 13 until partially passing through the sleeve 11, and at this time, in order to limit the size of the head 21 of the batch head 200 passing through the sleeve 11, the limiting member 12 cooperates with the head 21 of the batch head 200 to realize limiting. Specifically, the first contour portion 122 and the second contour portion 123 in the limiting hole 121 of the limiting member 12 are matched with the groove 211 and the protrusion 212 of the head 21, wherein the first contour portion 122 is located in the groove 211 of the head 21 in a plane perpendicular to the first axis Y, and the protrusion 212 of the head 21 is located in the second contour portion 123 of the limiting member 12 and is clamped with each other, so that the batch head 200 can only partially pass through the limiting hole 121 and contact with the first contour portion 122, thereby limiting the size of the part of the batch head 200 extending out of the sleeve 11, avoiding the extending-out length of the part, further enabling the sleeve 11 to better suck the screw, and realizing the operation of holding the screw with one hand.
Of course, in order to achieve the engagement between the limiting hole 121 of the limiting member 12 and the batch head 200, the sizes of the first contour portion 122 and the second contour portion 123 of the limiting member 12 also need to be set, for example, for the above-mentioned cross-shaped batch head 200, the first radius of the first contour portion 122 should be smaller than the size of the protrusion 212 from the center of the pattern and larger than the size of the groove 211 from the center of the pattern; the second radius of the second profile 123 should be greater than the dimension of the protrusion 212 from the center of the pattern; and the chord length of the first contour portion 122 should be larger than the distance between the ends of the adjacent two protrusions 212 far away from the head 21 in the flower pattern.
For the other types of the batch head 200, the sizes of the first contour portion 122 and the second contour portion 123 of the limiting member 12 are also set accordingly, and detailed description is omitted.
It should be noted that the batch head 200 in the present invention may be a separate batch head 200, or may be a batch head 200 with a connecting rod, or may be a batch head 200 integrally formed with a screwdriver; the batch head 200 may be a stripped batch head 200 or a batch head 200 without a strip. As shown in fig. 6, the limiting member 12 may be engaged with the peeling position of the batch head 200 to limit the peeling of the batch head 200. In the bit 200 with the extension bar, the stopper 12 may be engaged with a joint between the head 21 of the bit 200 and the extension bar to perform the stopper. That is, the stopper 12 is provided to make the fitting 100 of the present invention suitable for not only the most common peeling batch head 200 and batch head 200 with a connecting rod, but also the batch head 200 integrally formed with a screwdriver or batch head 200 without peeling, so that the fitting 100 can be suitable for more batch heads 200 with different specifications to realize a single hand nail operation. That is, the fitting 100 of the present invention can be applied to at least 95% of the commercially available generic lot headers 200, where the generic lot headers 200 are commonly referred to as standard lot headers commonly used in the market, such as the lot headers 200 that are not thinned or formed into other irregular shapes at the portion of the head 21 near the lot headers 200.
The above-described first embodiment shows the limiting member 12 formed separately from the sleeve 11, but in another second embodiment, the limiting member may also be formed together with the sleeve, which is not shown in the drawings. That is, a through hole is formed in the sleeve, the through hole extending in the first axial direction. The sleeve also comprises a first profile part and a second profile part which are positioned at the same axial position, the first profile part is used for forming a hole wall at the position with the smallest aperture of the through hole, the second profile part is used for forming a hole wall at the position with the largest aperture of the through hole, and in the radial direction of the through hole, the first profile part protrudes out of the second profile part. That is, in the second embodiment, the limiting member is not separately formed, but may be directly formed by the inner wall of the sleeve, and the structures of other parts of the sleeve, such as the stopping portion, the mounting sleeve, the functional member, and the end cap, may be applied to the same as those of the first embodiment.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by using equivalent alternatives or equivalent variations fall within the scope of the present invention.
