DETAILED DESCRIPTION

[0024] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0025] In the following description, terms such as "inside", "outside", "up", "down", "left", "right", etc. that indicate directions or positional relationships are only used to facilitate the description of the embodiments and simplify the description, and do not indicate or imply that the referred device or element must have a specific direction, be constructed and operated in a specific direction. Therefore, it should not be understood as a limitation on the present invention.

[0026] like Figure 1-Figure 4 As shown, a locking mechanism capable of realizing quick disassembly and assembly comprises a main body structure 1, notches 11 are formed on both sides of the main body structure 1, hooks 2 are embedded in the notches 11; a handle 6 is installed on both sides of the handle 6, a rotating shaft 4 is rotatably connected to a locking hook 5, and a thimble 8 capable of telescopic movement is arranged on the locking hook 5; the locking hook 5 is rotated to be inserted into the hook 2, and the thimble 8 on the locking hook 5 is extended to lock the hook 2 between the locking hook 5 and the thimble 8; accordingly, since the hook 2 is fixed inside the main body structure 1, the locking hook 5 will approach the hook 2 when it is rotated to be inserted into the hook 2, thereby driving the handle 6 connected thereto to approach the main body structure 1 and abut against the main body structure 1, thereby realizing the connection between the handle 6 and the main body structure 1.

[0027] A guide hole 12 is provided on the main structure 1, and a guide pin 3 that can cooperate with the guide hole 12 is provided on the handle 6. The guide hole 12 is located at the upper end of the slot 11, and one guide hole 12 corresponds to one slot 11. The guide pin 3 and the guide hole 12 cooperate to guide the connection between the hook 2 and the lock hook 5, and also facilitate the positioning between the main structure 1 and the handle 6, and improve the strength of the connection between the main structure 1 and the handle 6. The guide hole 12 is located at the upper end of the slot 11 to avoid interference when the hook 2 and the lock hook 5 are connected.

[0028] like Figure 3-Figure 4As shown, the main structure 1 and the handle 6 are locked: first, the guide pin 3 is inserted into the guide hole 12, and then the ejector pin 8 is controlled to retract and the lock hook 5 is rotated so that the lock hook 5 is stuck in the hook 2. Next, the ejector pin 8 is controlled to extend so that the head of the ejector pin 8 abuts against the hook 2, so that the lock hook 5 and the ejector pin 8 can lock the hook 2.

[0029] Among them, under the continuous reaction of the spring 9, the ejector pin 8 can be locked without the lock hook 5 reaching the dead point position, that is, at any angle after the lock hook 5 hooks the hook 2, the lock hook 5 and the ejector pin 8 can cooperate to achieve the locking function of the hook 2.

[0030] The main structure 1 and the handle 6 are unlocked by first controlling the ejector pin 8 to retract, and then rotating the lock hook 5 to disengage the hook 2, so that the handle 6 can be removed from the main structure 1.

[0031] The utility model achieves locking of the hook 2 by the cooperation of the lock hook 5 and the ejector pin 8, thereby enabling a quick connection between the handle 6 and the main structure 1. Meanwhile, the ejector pin 8 is continuously controlled by the spring 9, and the ejector pin 8 can cooperate with the lock hook 5 to lock the hook 2 at any angle at which the lock hook 5 and the hook 2 are hooked.

[0032] An accommodation space 51 is formed inside the lock hook 5, and a shift block 7 and a spring 9 are arranged in the accommodation space 51; the middle of the shift block 7 is hollow, and the spring 9 passes through the middle of the shift block 7. A shift block hole 71 is formed on the top of the shift block 7, and an internal thread is formed in the shift block hole 71. A protrusion 72 that can control the forward and backward movement of the shift block 7 is formed on the outward side of the shift block 7.

[0033] The ejector pin 8 includes an ejector pin portion 81 and a connecting portion 82 . An outer wall of the connecting portion 82 is formed with an external thread. The external thread of the connecting portion 82 is connected with an internal thread of the shift block hole 71 , so that the ejector pin 8 is fixed on the shift block 7 .

[0034] The tail of the connecting portion 82 is connected to one end of the spring 9 , and the other end of the spring 9 is fixed on the locking hook 5 .

[0035] Specifically, the protrusion 72 moves toward the side of the handle 6, driving the ejector pin 8 fixedly connected to the shift block 7 to move toward the side of the handle 6, and the ejector pin 8 retracts and squeezes the spring 9, so that the spring 9 is compressed after being subjected to force, and the ejector pin 8 does not cooperate with the locking hook 5 to achieve the locking of the hook 2; the protrusion 72 moves toward the side of the main structure 1, driving the ejector pin 8 fixedly connected to the shift block 7 to move toward the side of the main structure 1, and the ejector pin 8 extends out and is subjected to the continuous reaction force of the spring 9, so as to always maintain the state of abutting the hook 2, and the ejector pin 8 cooperates with the locking hook 5 to achieve the locking of the hook 2, thereby achieving the connection between the handle 6 and the main structure 1.

[0036] A threaded hole 21 is formed on the hook 2 , and the hook 2 is fixedly connected to the main structure 1 by bolts, so that the hook 2 has a stable position, which makes it convenient for the lock hook 5 to hook the hook 2 .

[0037] The lock hook 5 includes a lock hook handle 52 , which is located at the rear of the lock hook 5 and is used to control the rotation of the lock hook 5 .

[0038] Compared with bolt connection, the utility model is faster and more convenient, and has higher connection strength than other clamping structures. At the same time, under the premise that the lock hook 5 and the hook 2 are hooked, the lock hook 5 and the hook 2 are at different angles, and the ejector pin 8 can cooperate with the lock hook 5 to lock the hook 2.

[0039] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention; therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.

[0040] Although this article uses more of the figure markings: main structure 1, hook 2, guide pin 3, shaft 4, lock hook 5, handle 6, shift block 7, ejector pin 8, spring 9, notch 11, guide hole 12, threaded hole 21, placement space 51, lock hook handle 52, shift block hole 71, protrusion 72, ejector pin portion 81, connecting portion 82 and other terms, it does not exclude the possibility of using other terms; these terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
