A safety water bottle that is normally hung on a multifunctional shelf in the classroom

technical field

The invention relates to sanitary utensils for middle and primary schools, namely safety water bottles normally hung on a multifunctional shelf in classrooms.

Background technique

Chinese Patent No. 201320010875.0 provides a dual-use kettle consisting of a kettle body, a nozzle, a nozzle, a water inlet cover, a water faucet, etc. The kettle is hung on the middle of the rear side of the multi-functional rack in primary and secondary school classrooms through a pick, and the lower part of the side is equipped with The faucet is suitable for teachers and students to wash their hands in time in the classroom (such as the chalk dust on the hands of teachers after class), and the hand-washing water directly falls into the cleaning bucket below (the amount of water in the cleaning bucket will be suitable for simple rinsing of mops and brooms by the evening. The rear mop and broom are also hung on the back side of the multi-functional rack to drain water, so that they no longer touch the ground to get dirty). If the water bottle is removed from the multi-functional rack, it can be used for ground cleaning and watering. Because the front side of the multi-function shelf for classroom housekeeping is blocked by the solid board for writing or posting, the kettle and so on will not be seen by the students in the seat. The overall product of the multi-function shelf is simple and the planning is reasonable and practical.

The connection between the above-mentioned dual-use water bottle and the multi-function rack is a steel pick piece obtained by stamping. The pick piece includes three sections: the base, the middle arm, and the front folding section. , the front folded section is connected to the pot hanging button on the top surface of the pot body. The length of the pick piece is large, especially when the kettle is full, the torque output by the pick piece base is large, so the connection structure strength of the cross bar is quite high. Also, because the operator's hand is close to the steel pick and not covered, especially for young elementary school students with weak arm strength, if they are slightly negligent, they may be squeezed or scratched by the steel pick. There is a certain degree of safety hazard in use.

SUMMARY OF THE INVENTION

The task of the present invention is to provide a dual-use water bottle that is suitable for being mounted on a multifunctional shelf in primary and secondary school classrooms and is normally hung.

The design scheme of the present invention: the safety water bottle normally hung on the classroom multi-functional rack, the multi-functional rack includes the connected front and rear sheets, and is supported on the ground by the opposite of the front and rear sheets. It is made up of left and right side bars and several horizontal bars. A bottom fence is connected between the lower ends of the front and rear pieces. The basic daily objects of the classroom are placed in an orderly manner from top to bottom on the rear side of the front piece. The main body of the pot, the nozzle, the sprinkler head, the faucet and the mouth cover, the water faucet is assembled on the lower end of the side of the main body of the pot, and the top surface of the main body of the pot is provided with a handle and a water inlet; and:

An epitaxial head plate on the side of the main body of the pot, or an epitaxial head plate on the bottom plate fixed on the surface of the main body of the pot;

The enclosure is fixed on the crossbar a of the front piece of the multi-function frame, or a cutout is made on the upper side of the crossbar a;

The front crossbar b of the multi-functional rack is provided with a special-shaped pad to assist the main body of the pot to maintain an upright posture in space;

The carrying of the dual-use water bottle on the multi-functional rack is realized by the insertion of the head plate into the upper opening of the enclosure, or the insertion into the a-notch of the crossbar.

A mouthpiece is arranged between the side cut on the crossbar a and the head plate of the main body of the pot.

The special-shaped pad includes a side plate or/and a limit for fitting the protruding strip under the head plate of the main body of the kettle.

The self-contained body composed of the bottom plate and the head board can be called the upper card.

The positive effect of the design: the dual-use water bottle is attached to the crossbar a of the multi-function rack by means of a bracket or a sleeve, and the hook is not forcedly locked, thereby facilitating the operation of the dual-use water bottle to be attached and evacuated. The special-shaped pad carried on the crossbar b on the front piece of the multifunctional rack can easily and effectively correct and maintain the space upright posture of the dual-use water bottle. The head board, sleeve mouth and enclosure are far away from the operator's hand, and the end of the handle is rigidly spaced, so teachers and students are fully safe to use the kettle. The dual-use water bottle in this design enriches the application content of the multi-function rack.

Detailed ways

Example 1. Referring to Figure 1a: the classroom multi-purpose rack is an integrated application product, which includes two equal-length side bars (111), a crossbar a (112), a crossbar b (113) and other crossbars (114). The front piece, and the rear piece formed by connecting two equal-length side bars (121) and cross bars (122), the upper end of the rear side bar (121) is connected to the middle of the front side bar (111) to form mutual support, slightly higher The bottom fence (13) on the ground is fixedly connected between the lower end of the front piece and the rear piece, the classroom sanitary bucket (14) and the special cleaning bucket (15) are placed on the bottom fence (13), and the multi-functional rack stands stably on the ground . The solid board arranged between the left and right rods (111) of the front piece (for the writing of temporary notices and the posting of the contents on the paper, and it is convenient for erasing or clearing), and covers the attached sub-products hanging on the rear side ( The mop, broom, etc. in the middle and upper part of the right side of Figure 1a), so that the students in the seat cannot be seen. The dual-use water bottle used for washing hands and sprinkling water to wet the ground is also one of the sub-products that are covered.

In the overall planning of the multi-function rack product, it is set that the water flowing out of the faucet (33) of the dual-use kettle should fall into the special cleaning bucket (15) directly below after washing hands, so the cross bar a (112) is located in the special cleaning bucket (112). 15) at a suitable height above, and the cross bar b (113) is located near the lower part of the cross bar a (112) (obviously still above the special cleaning bucket (15)).

Refer to Figure 3d-e: the main body (2) of the pot can have two styles of left and right symmetry, the difference lies in the position of the vertical concave area (23) for assembling the faucet, but the left and right distinction of the main body (2) has nothing to do with it. Design of the hooking structure (head plate (41), enclosure (5), special-shaped pad (6), etc.) on the multifunctional rack. Except for the main body (2) of the kettle, the design is the same as the previous dual-use kettle (see Fig. 1c) in that it is equipped with a nozzle (31), a sprinkler head (32), and a water tap (33). The sprinkler head (32) is assembled on the At the upper end of the spout (31), the faucet (33) is assembled in the vertical concave area (23) on the side of the pot, the top surface of the main body of the pot is provided with a handle (21) and a water inlet (22), and the water inlet (22) is provided with a mouth cover (34). ).

1a-e: the hooking system of the original dual-use water bottle to the crossbar a (112) of the multifunctional rack is realized by the pick piece (16), and the pick piece (16) is relatively long (about 15cm in the actual product), especially When the kettle is full, the hook (25) on the top surface of the kettle is pierced by the front folded section (162) of the pick (see Fig. 1e for details), and the torque output from the rear end base (161) of the pick is quite large, so that the The structural strength requirements of the connection between the cross bar a (112) and the side bar (111) are quite high; in addition, the pick (16) is generally a steel part obtained by stamping. If you are slightly negligent in use, your hands may be squeezed and scratched, and there is a certain degree of safety hazard.

Referring to Figures 2f-g: a head plate (41) is extended from the side of the main body (2) of the pot. See Figures 2a-j: the enclosure (5) is a metal stamping part or a high-strength injection molded part, which is fixed (eg, riveted, or bonded and compounded riveted) on the front crossbar a (112) of the multifunctional frame, and the enclosure (5) ) The middle part is easy to fit the flat middle plate (52) fixed on the cross bar a (112), and the small plates (51) at both ends of the upper part are hugged to one side of the middle plate (52) to form an upper opening (52) that is released on one side. 53). The head plate (41) on the side of the pot body (2) is inserted into the upper opening (53) of the enclosure, and the weight of the pot is borne by the crossbar a (112) attached to the enclosure (5). Since the upper side of the crossbar a (112) is slightly inclined in the space (with the front piece of the multi-function stand), the more important factor is that the head plate (41) is on the side of the main body (2) of the pot, so the pot wants to move from the crossbar a. (112) slides down, but is strongly stopped by the upper mouth (53) of the enclosure. Therefore, the main body (2) of the pot is reliably hooked on the cross bar a (112) by means of the enclosing member (5).

Since the head plate (4) is on the upper side of the main body (2) of the kettle, if only the head plate (41) is attached to the cross bar a (112), although the kettle will not fall, its own weight will inevitably cause it to fall in The space is naturally inclined, which is inconvenient for teachers and students to wash their hands and other practical applications, and the spatial stability is poor. Referring to Figures 2a and 4a-b: the special-shaped pad (6) is fixed to the crossbar b (113), the crossbar b (113) is located adjacent to the crossbar a (112) below, the special-shaped pad (6) and the enclosure (5) ) is aligned in the center, the space height of the cross bar b (113) and the special-shaped pad (6) corresponds to the space height of the lower part of the pot body (2), at this time, the thickness of the special-shaped pad (6) in the horizontal direction just makes the pot body (2) In an upright posture in space.

See Figure 2a, Figure 2d, Figure 2f: the outer side of the special-shaped pad (6) is provided with a limit (62), the surface of the pot body (2) below the head plate (41) is provided with a protruding strip (24), and the special-shaped pad limit (62) ) corresponds to the position of the protruding strip (24) of the main body of the pot, that is, when the main body (2) of the pot is hung on the upper opening (53) of the enclosing member of the cross bar a, the protruding strip (24) is just thrown into the limiting opening (62). It is worth noting that: referring to Figures 2d and 2f in combination with Figures 4a-b, since the head plate (41) is located on the upper side of the kettle body (2), the full kettle is subject to gravity (the actual water volume of the kettle product reaches several Kilogram), the protruding strip (24) of the main body of the pot will be automatically inserted into the special-shaped pad limit (62), and the actual situation is that the more water in the pot, the tighter the pot body is against the special-shaped pad (6) (the pot body and the water A part of gravity is decomposed into lateral pressure on the special-shaped pad (6), that is, the side near the protruding strip (24) is closely attached to the side where the limit opening (62) is located), so the hook of the kettle on the crossbar is self-stabilizing. Mechanism, good spatial stability and easy application; however, as the faucet drains and washes hands, or even there is no water in the pot, the pressure on the side elevation of the pot body (2) on the special-shaped pad (6) is gradually reduced to a minimum value (the overall weight of the empty pot is only Hundreds of grams), at this time, it is convenient for the kettle to be easily removed from the upper mouth (53) of the enclosure and refilling.

The side plates (61) at both ends of the special-shaped pad (6) are in contact with one side elevation of the main body (2) of the pot (that is, the elevation of the side where the head plate (41) is located). strengthen. (Refer to Figure 2i-j: the head plate (41) in the upper part of the figure is only in a plug-in relationship with the upper port (53), and the special-shaped pad (6) in the lower part is only abutting and not sticking to the main body (2) of the pot.)

According to the above, even considering that teachers and students need to manually discharge water by using the faucet to wash their hands, this operation should not be enough to disturb the attachment of the main body (2) of the kettle and its upright state in space. If the whole multifunctional rack or the main body (2) of the pot is accidentally bumped or vibrated, the main body (2) of the pot generally will not fall off from the cross bar a (112) due to the appropriate depth of the upper opening (53) of the enclosure (in the event of a strong earthquake). Even if the posture of the main body (2) of the kettle is deviated, it will return to the upright state by itself under the action of the gravity of the kettle body and the water in the kettle.

The hooking of the dual-purpose water bottle on the crossbar a (112) of the multi-functional rack, the holding of the main body (2) of the water bottle by the special-shaped pad (6), and the maintenance of its upright posture in space require few components and a simple structure. , the effect is sufficient, and there is no forced locking, the operation of hooking up the dual-use kettle with water on the horizontal bar a (112) and evacuating the empty kettle to take water are quite simple.

Referring to Figures 3a-e: if the head plate (41) is not directly extended from the side of the pot body (2), the bottom sheet (42) can be attached to the side of the pot body (2), and the head plate (41) Extend from the negative wafer (42). The composite body of the head plate (41) and the bottom plate (42) is an upper card (4), and the upper card (4) can be obtained by punching or punching and welding, and can also be obtained by integral injection molding. The backing sheet (42) may not be curved as shown in Figs. 3a-b, but it is curved or flat, depending on the local shape of the body surface of the pot body (2) where it is attached.

Example 2. The enclosure (5) in Example 1 is dispensed with. A cutout (1121) is obtained by punching on the upper side of the crossbar a (see Figure 5d in particular), so that the head plate (41) of the kettle body is directly inserted into the cutout (1121) on the upper side of the crossbar a, then the dual-use kettle has been reliably hooked to the crossbar a(112).

Example 3. Refer to Figure 5d-e: construct the sleeve (7) so that the lower part of the sleeve (7) sinks into the cavity of the cross bar a (pipe) from the incision (1121), and the mouth surface layer of the sleeve (7) is in the horizontal The upper side of the rod a (112) is glued. When the head plate (41) of the main body of the kettle is inserted into the sleeve opening (7) (the lower bottom of the sleeve opening (7) can be closed or not closed), the dual-use kettle has been reliably hooked to the crossbar a(112), the same as in Example 2. In this example, the connection situation of the main body of the pot is simple in appearance, which is a preferred embodiment.

The following continues to describe the design:

①See Figure 3d-e: the main body (2) of the kettle in the two figures is symmetrical. If the kettle in Figure 3d is called a right-handed kettle, then the kettle in Figure 3e is a left-handed kettle. In this design, the water bottle is hung on the rear side of the front panel of the multi-functional rack for classroom housekeeping. (The person who is to wash their hands may stand outside the left side of the multi-function rack, or may stand outside the right side of the multi-function rack). The faucet (33) should be located in an easy-to-discharge position. Operation, in a classroom should be based on the relative positional relationship between the podium and the multi-functional rack to decide the choice of the above two kinds of kettles (left and right-handed systems).

② The main body (2) of the pot in this design can be a cuboid as shown in the attached drawings, or it can be cylindrical or other shapes; 2) Assembly at a certain position at the lower end of the side elevation (directly punching holes to connect the inside and outside of the pot), but such changes do not affect the relevant structural essence of the pot body (2) hooking the crossbar of the multi-function rack on a certain side.

③Refer to Figure 6a-c: if the upper side of the crossbar a (112) is deformed by pressing to form a shallow sink (1122) similar to the cutout (1121) of the crossbar a, so that the head plate (41) of the main body of the pot is shallowly connected to the A shallow sink groove (1122); or the upper side of the cross bar a (112) is treated as a front inclined surface, and the head plate (41) of the main body of the pot is generally placed on the front inclined surface and will not fall autonomously, but the hooking reliability is poor; or By imitating the enclosure (5) of this design, the rear side of the cross bar a (112) is extended upward, and the head plate (41) of the main body of the pot is blocked by the extended side and can still be attached; the above situations are all short-term effects of this design. Deterioration.
