Description

Technical Field

[0001] The utility model relates to the field of boxes, in particular to a snap-on box and a box snap-on connection structure. Background Art

[0002] Square boxes are a commonly used packaging box (usually used to place various tools). In order to facilitate the management and stacking of multiple boxes, a modular box group is disclosed in the patent announcement document CN209064580U. This modular box group essentially clamps and fixes multiple boxes with the help of flip-type lock clips. However, since the lock clips of this modular box group are set on the side walls of the boxes and there is no protective structure between the lock clips, it is very easy for the lock clips to be disengaged due to foreign objects touching the lock clips during actual use, resulting in the disengagement of the two boxes that are locked together. Utility Model Content

[0003] The utility model aims at solving the above problems and provides a snap-on box.

[0004] The technical solution adopted by the utility model is as follows:

[0005] 14. The locksmith claim 13, wherein the locking cam is provided with a first locking cam which is provided on the locking cam side and a second locking cam which is provided on the locking cam side.

[0006] In this snap-on box, the two box bodies can be snap-fitted with each other with the help of the main clamping hook, the auxiliary clamping hook, the main clamping groove and the auxiliary clamping groove. After the snap-fitting is achieved, the main clamping hook and the main clamping groove are matched together, and when the main clamping hook and the main clamping groove are matched together, the reset spring has a tendency to drive the main clamping hook to snap into the main clamping groove. In this way, even if an external object touches the rotating block and causes the rotating block to rotate, causing the main clamping hook and the main clamping groove to disengage, the main clamping hook can still be snapped into the main clamping groove due to the presence of the reset spring, thereby avoiding the two matched box bodies from disengaging, thereby improving the stability of the box body matching.

[0007] To sum up, in this type of snap-on box, the main clamping hook is set on the rotating block and a reset spring is set in the installation groove. Even if a foreign object touches the rotating block and causes the rotating block to rotate, resulting in the main clamping hook and the main clamping groove being disengaged, the main clamping hook can still be clamped into the main clamping groove due to the presence of the reset spring, thereby avoiding the separation of the two box bodies that are matched together and improving the stability of the box body matching.

[0008] In this snap-on box, in order to improve the stability of the reset spring in the installation groove, a first set of columns is further provided on the box body, and a second set of columns is provided on the rotating block. The two ends of the reset spring are respectively provided on the first set of columns and the second set of columns, wherein the first set of columns is cylindrical and the second set of columns is cylindrical.

[0009] Optionally, the main clamping hook is an L-shaped main clamping hook, a chamfered inclined surface is provided on the main clamping hook, and an arc guide clamping inclined surface is provided on the rotating block.

[0010] The chamfered surface on the main clamping hook is to enable the main clamping hook to slide smoothly into the main clamping groove so as to be stably clamped in the main clamping groove. The function of the arc guide clamping slope on the rotating block is to prevent the rotating block from scratching the wall of the box or box when other boxes or boxes come into contact.

[0011] Optionally, a positioning recess is provided on the first end surface, and a positioning protrusion is provided on the second end surface, and the positioning protrusion is used to cooperate with the positioning recess.

[0012] The positioning concave and the positioning protrusion play a role in positioning two boxes that fit together.

[0013] Optionally, a resistance surface is provided on the mounting groove, and a contact surface is provided on the rotating block, and the resistance surface is used to contact the contact surface.

[0014] The contact surface and the resistance surface have a function of limiting the rotation amount of the rotating block. When the rotating block rotates until the contact surface and the resistance surface come into contact, the rotating block will not be able to continue to rotate.

[0015] Optionally, a main guide slide and a secondary guide slide are provided on the first end surface, the main guide slide is located at the main clamping groove, and the secondary guide slide is located at the secondary clamping groove.

[0016] The function of the main guide slide is to facilitate the main clamping hook to slide into the main clamping groove and be clamped, while the function of the secondary guide slide is to facilitate the secondary clamping hook to slide into the secondary clamping groove and be clamped.

[0017] A box snap-fit ​​connection structure comprises the snap-fit ​​box and a box body as described above, wherein the box body is provided with a receiving end surface, and the receiving end surface is provided with a main snap-fit ​​groove and a secondary snap-fit ​​groove, wherein the main snap-fit ​​groove is snap-fitted with the main clamping hook, and the secondary snap-fit ​​groove is snap-fitted with the secondary clamping hook.

[0018] The box body with the main clamping groove and the auxiliary clamping groove is used to cooperate with the snap-on box. When the box body and the snap-on box are clamped together, the receiving end surface on the box body and the second end surface of the box body are in a tightly attached and flush state.

[0019] In the present connection structure, the snap-on box and the box body can be boxes of different sizes or boxes of different uses.

[0020] Optionally, an introduction slope is provided on the box body, and the introduction slope is located at the main clamping groove.

[0021] The specific function of the guide slope is to contact with the chamfered slope on the main clamping hook to ensure that the main clamping hook can smoothly slide into the main clamping groove and be clamped.

[0022] Optionally, a recessed groove is provided at the receiving end surface of the box body, and the positioning protrusion is located in the recessed groove.

[0023] Optionally, the box is a square box.

[0024] Optionally, the box body is a square box body.

[0025] The beneficial effect of the utility model is that the main clamping hook is arranged on the rotating block and a reset spring is arranged in the installation groove. Even if a foreign object touches the rotating block and causes the rotating block to rotate, resulting in the main clamping hook and the main clamping groove being disengaged, the main clamping hook can still be clamped into the main clamping groove due to the presence of the reset spring, thereby preventing the two matched boxes from being disengaged and improving the stability of the box matching.
