DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] The following will describe the present invention in detail in conjunction with the attached Figure 1 to the attached Figure 7 and specific embodiments.

[0030] As Figures 1 to 7 shown, the present invention provides a bolt assembly for assembling two connected parts 8 into one body. The connected parts 8 can be two split box frames, but are not limited thereto. The bolt assembly of the present application includes a connection seat 1, a lock case 2 fixed on the connection seat 1, a lock rod 3 movably arranged in the lock case 2, and a handle 4 vertically fixed on the lock rod 3. Among them: a travel groove 21 extending along the length direction is formed on the side wall of the lock case 2, and a first limit groove 22 and a second limit groove 23 which are communicated with the travel groove 21 and located on one side of the travel groove 21 are formed on the top wall of the lock case 2. When the handle 4 moves from the first limit groove 22 through the travel groove 21 to the second limit groove 23, the lock rod 3 is in a locked state; when the handle 4 moves from the second limit groove 23 through the travel groove 21 to the first limit groove 22, the lock rod 3 is in an unlocked state; when the lock rod 3 is in a locked state or an unlocked state, the handle 4 is vertically arranged. It can be known that the handle 4 is fixed on the lock rod 3, and the movement of the handle 4 will drive the lock rod 3 to move together. An insertion end 32 is formed at one end of the lock rod 3 away from the lock case 2. When the handle 4 moves into the second limit groove 23, the insertion end 32 extends out and inserts into the insertion hole of the connected part to achieve connection; when the handle 4 moves into the first limit groove 22, the insertion end 32 retracts backward and leaves the connected part, so that the connected part can be separated from the bolt assembly.

[0031] In the present application, the first limit groove 22 and the second limit groove 23 are arranged at the top of the lock case 2, so that the handle 4 is vertically arranged in both the unlocked state and the locked state, avoiding the handle 4 exceeding the edge of the connected part, improving the safety during transportation and use, and at the same time ensuring that there is no interference with adjacent boxes or other objects.

[0032] It should be noted that the present application does not limit the way the handle 4 enters the first limit groove 22 or the second limit groove 23 from the self-travel groove 21. For example, the handle 4 can be manually lifted upward so that the handle 4 is clamped in the first limit groove 22 or the second limit groove 23, and the handle 4 cannot easily leave the first limit groove 22 or the second limit groove 23. In the above manner, the groove shapes of the first limit groove 22 and the second limit groove 23 need to be specially set, and the side openings preferably have a certain elastic deformation so that the lower end of the handle 4 can be clamped therein, but this is not limited thereto.

[0033] In some embodiments, referring to Figures 3 to 5 , a return unit 5 for providing a turning power to the lock rod 3 is provided on the lock rod 3; at the locking position or the unlocking position, the handle 4 automatically returns to the second limit groove 23 or the first limit groove 21 under the action of the return unit 5. In other words, the return unit 5 has the function of turning the handle 4 to a vertical state. When the handle 4 moves to the opening of the first limit groove 22 or the second limit groove 23 in the travel groove 21, the return unit 5 automatically makes the handle 4 enter the first limit groove 22 or the second limit groove 23 and be in a vertical state, ensuring that the handle 4 automatically remains vertical in the locked or unlocked state, which can not only avoid interference with other adjacent components, but also make the overall structure of the box body beautiful. Due to the setting of the return unit 5 in the present application, the situation that the lock rod 3 slides in place and inserts into the connected part but forgets to lock it, resulting in potential safety hazards, is avoided. In the above embodiments, the openings of the first limit groove 22 and the second limit groove 23 should be appropriately large so that the handle 4 can easily enter under the action of the return unit 5.

[0034] In a specific embodiment, the return unit 5 is a return spring sleeved on the lock rod 3, and the return spring drives the lock rod 3 to turn, and then drives the handle 4 to turn.

[0035] Specifically, a support 6 is provided at one end of the lock rod 3 located inside the lock housing 2, a limit step 31 is formed at one end of the lock rod 3 close to the support 6, one end of the return spring abuts against the support 6, the other end of the return spring abuts against the limit step 31, and the return spring is fixed on the lock rod 3 through a fixing member. Preferably, the return spring is a torsion spring. After the lock rod 3 is rotated by a certain angle under an external force and then the external force is removed, the lock rod 3 will return to the initial position under the action of the return spring. The initial position of the present application is the position where the handle 4 is in a vertical state.

[0036] Specifically, referring to Figure 5, the support member 6 includes a support portion 61 and a sliding portion 62. The support portion 61 is connected to one end of the locking rod 3 through a first fixing member 63, and the locking rod 3 is rotatably arranged on the support portion 61. The support portion 61 provides a limit for the return spring. A chute 11 adapted to the sliding portion 62 is formed on the connecting seat 1. When the locking rod 3 moves, the sliding portion 62 moves along with the locking rod 3 and is arranged in the chute 11. The sliding portion 62 provides a guide for the movement of the locking rod 3.

[0037] In some embodiments, referring to Figure 5 , Figure 6 , a guide groove 24 extending along the length direction is formed in the lock housing 2. The locking rod 3 is movably arranged in the guide groove 24. One end of the guide groove 24 communicates with the outside through a stroke groove 21, a first limiting groove 22, and a second limiting groove 23. That is, the other end of the locking rod 3 far from the insertion end 32 is movably arranged in the guide groove 24 and only moves within the range of the chute 11. The arrangement of the guide groove 24 restricts the degree of freedom of the locking rod 3, so that the locking rod 3 can only move along the length direction of the lock housing 2 and ensures that the insertion end 32 can be accurately inserted into the connected member.

[0038] Specifically, referring to Figures 1 to 4 , the connecting seat 1 has an L-shaped structure. The vertical end of the connecting seat 1 is fixedly connected to one of the connected members, and the locking rod is movably installed on the horizontal end of the connecting seat 1 and is detachably connected to the other connected member. Further, the connecting seat 1 includes a vertically arranged first connecting plate 12 and a horizontally arranged second connecting plate 13. A threaded hole is formed in the first connecting plate 12, and a through hole is formed in the connected member connected to the first connecting plate 12. A bolt or screw passes through the through hole and is screwed into the threaded hole to realize the connection between the first connecting plate 12 and one of the connected members 8. The lock housing 2 and the locking rod 3 are installed on the second connecting plate 13 for connecting to the other connected member 8. Of course, the L-shaped structure of the above-mentioned connecting seat 1 is only a preferred embodiment. In other embodiments, the specific structure of the connecting seat can be designed according to the positional relationship between the two connected members. As long as all the connecting seats that can connect two connected members with different positions into one body belong to the protection scope of the present application.

[0039] Specifically, the lock housing 2 is fixedly connected to the connecting seat 1 through a second fixing member 7.

[0040] Referring to Figure 7 , the present utility model further provides an LED display box body, which includes a first frame and a second frame. The first frame and the second frame are equivalent to two connected members 8, and further includes the plug-in component of any one of the above. The first frame is fixed to one end of the connecting seat 1, and a plug-in hole is formed in the second frame. The free end of the locking rod 3 faces the plug-in hole, and when the handle 4 moves from the first limiting groove 22 through the stroke groove 21 to the second limiting groove 23, the locking rod 3 is inserted into the plug-in hole.

[0041] The present utility model further provides an LED display screen, which includes the pin assembly of any one of the above.

[0042] Since the LED display screen box body and the LED display screen of this embodiment adopt all the technical solutions of all the embodiments of the above pin assembly, they at least have all the beneficial effects brought by the technical solutions of the embodiments of the above pin assembly, and will not be elaborated one by one here.

[0043] The above further describes the present utility model with the aid of specific embodiments. However, it should be understood that this specific description should not be construed as a limitation on the essence and scope of the present utility model.
