Box limit device and box

Abstract

The invention discloses a box body limiting device and a box body. The box body includes an upper box body and a lower box body, and a card slot is arranged on the upper box body. The box body limiting device includes: a snap spring, including a body, The clamping part and the ring-shaped hook, the clamping part is used to cooperate with the card slot, and there is an opening between the end of the ring-shaped hook and the body; it is used to fix the overlapping block on the lower box body, and the overlapping block includes at least Two vertical blocks and the connecting part connecting the vertical blocks, the connecting part includes a cylinder and a cam body, the cylinder is stuck in the hook, and the cam body cooperates with the opening to limit the position; the diameter of the cylinder is larger than the width of the opening; the cam body The sum of the height and the diameter of the cylinder is greater than the inner diameter of the hook. The box body limiting device and the box body provided by the present invention solve the problem that the clip spring is easy to fall off and difficult to assemble in the prior art by using the simple structure of size matching between the clip spring and the lap block, and the design of the cam body size determines the clip The active angle of the spring simplifies assembly.

Description

technical field [0001] The invention relates to the sealing and position-limiting technology of a split box body, in particular to a box body position-limiting device and a box body. Background technique [0002] The split box structure is widely used in various industries. In the automotive industry, such as air filters, air conditioner filters, relay boxes, etc., the upper and lower box structures are used to facilitate disassembly and maintenance. [0003] Some boxes, such as air filters and cabin filters, have filter elements inside, so it is necessary to ensure their tightness. The split box body in the prior art is usually sealed by means of clamping ring clamping or bolt tightening. [0004] For the clamping method of the clamping ring, a clamping groove is provided on the box body, and the clamping spring cooperates with the clamping groove to realize the sealing between the upper and lower box bodies. However, after the clamping spring is separated from the clampin...

AI Technical Summary

Problems solved by technology

[0004] For the clamping method of the clamping ring, a clamping groove is provided on the box body, and the clamping spring cooperates with the clamping groove to realize the sealing between the upper and lower box bodies. However, after the clamping spring is separated from the clamping groove, the The circlip is easy to interfere and scratch with the surrounding parts, and the circlip is also easy to fall off

[0005] For the bolt tightening method, the installation and disassembly time is long, and tools are needed during the disassembly process, which makes the disassembly convenience poor
