Abstract
Description
Technical Field
[0001] This invention relates to a detachable locking structure, and more particularly to a detachable locking structure for use in a vehicle. Background Technology
[0002] With the increasing demand for diverse and customized storage space in automobiles, there is a need to add detachable modular structures. However, the current cover switch locking structure is complex, troublesome to assemble and replace, and costly. Therefore, a simple, reliable, and low-cost detachable locking structure is needed. Summary of the Invention
[0003] The purpose of this invention is to address the aforementioned problems in the prior art by proposing a detachable locking structure.
[0004] The objective of this invention is achieved through the following technical solution: a detachable locking structure, comprising a housing and a panel, wherein a limiting cam, a locking block, a rotating shaft, a torsion spring, and a spring are provided inside the housing; the front end of the limiting cam is bent forward into an arc shape and the rear end is extended to form a protrusion; the torsion spring is mounted on the limiting cam; the rotating shaft passes through the limiting cam and the housing; the front end of the locking block forms a protrusion and the two ends of the middle part are extended to form a cylinder; the locking block is engaged with the housing; and the spring is mounted in the housing and the locking block.
[0005] The panel includes an outer panel and an inner panel. When the panel is installed, the detachable locking structure is in the unlocked state. When a downward force is applied to the outer panel, the pin of the outer panel moves downward in the groove. The lower end of the pin abuts against the front end of the locking block under the action of the external force, and they move downward together under the action of the external force. The protrusion on the locking block moves downward and separates from the rear end protrusion on the limiting cam. The front end of the limiting cam rotates under the rebound action of the torsion spring and abuts against the upper end of the pin to lock. The panel installation is completed.
[0006] The inner plate has a groove, and the outer plate has a pin that moves up and down within the groove. When the panel is disassembled, the detachable locking structure is locked. When an upward force is applied to the outer plate, the pin of the outer plate moves upward in the groove. The upper end of the pin presses against the front end of the limiting cam and moves upward. The rear end protrusion of the limiting cam rotates on the rotating shaft. The locking block springs downward under the force of the rear end protrusion. After the panel is completely disassembled, the locking block springs upward under the return of the spring. The limiting cam rotates around the rotating shaft under the action of the torsion spring. The rear end protrusion of the limiting cam abuts against the protrusion on the locking block and locks it.
[0007] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0008] The locking structure of this invention is simple and ingeniously designed. It uses a one-time injection molded limiting cam, locking block and rotating shaft to achieve locking. The ingenious design of the limiting cam and locking block makes the inner plate locked and limited. At the same time, this invention uses fewer parts, is easy to assemble and replace, and has low cost, which can effectively reduce product cost. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present invention.
[0018] Please see Figures 1-7 This invention relates to a detachable locking structure, comprising a housing 1 and a panel 2, the panel 2 being composed of an outer panel 11 and an inner panel 12. The housing 1 is provided with a limiting cam 3, a locking block 4, a rotating shaft 5, a torsion spring 6, and a spring 7. The front end of the limiting cam 3 is bent forward into an arc shape, and the rear end is extended to form a protrusion 9. The torsion spring 6 is mounted on the limiting cam 3. The rotating shaft 5 passes through the limiting cam 3 and the housing 1, causing the limiting cam 3 to rotate around the rotating shaft 5. The front end of the locking block 4 forms a protrusion 10, and the two ends of the middle part are extended to form a cylinder, so that the locking block 4 is engaged in the housing 1. The spring 7 is engaged in the locking block 4 and the housing 1.
[0019] A groove 13 is made on the inner plate 12, and a pin 14 is made outward on the outer plate 11, which moves up and down in the groove 13.
[0020] When panel 2 is installed, the detachable locking structure is in the unlocked state. When a downward force is applied to outer panel 12, the pin 14 of outer panel 11 moves downward in groove 13. The lower end of pin 14 abuts against the front end of locking block 4 under the action of external force, and moves downward together under the action of external force. The protrusion 10 on locking block 4 moves downward and separates from the rear end protrusion 9 on limiting cam 3. The front end 8 of limiting cam 3 rotates under the rebound action of torsion spring 6 and abuts against the upper end of pin 14 to lock. Panel 2 is then installed.
[0021] When panel 2 is disassembled, the detachable locking structure is in a locked state. When an upward force is applied to outer panel 11, the pin 14 of outer panel 11 moves upward in groove 13. The upper end of pin 14 presses against the front end 8 of limiting cam 3 and moves upward. The rear end protrusion 9 of limiting cam 3 rotates on the rotating shaft 5. Locking block 4 is pushed downward by the force of rear end protrusion 9. After panel 2 is completely disassembled, locking block 4 is pushed upward by the rebound of spring 7. Limiting cam 3 rotates around rotating shaft 5 under the action of torsion spring. The rear end protrusion 9 of limiting cam 3 abuts against the protrusion 10 on locking block 4 and locks it.
[0022] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the present invention will be included within the scope of the claims.
