Description

Arc lock capable of adjusting gap of LED display screen box body Technical Field The invention relates to the field of installation and splicing of LED display screens, in particular to an arc lock capable of adjusting the gap of a box body of an LED display screen. Background The LED display screen is widely applied in the fields of advertisement media, stage performance, conference display and the like, and is generally assembled by a plurality of independent display screen boxes through a splicing structure. In order to meet diversified visual presentation requirements, particularly for constructing an arc screen or a special-shaped screen, the box body connecting lockset not only needs to bear a structural connecting function, but also needs to have angle adjusting capability. However, the existing lock for connecting the box body of the LED display screen still has defects in practical application. Firstly, in the aspect of connection fastening, the conventional connecting device often lacks an effective axial pre-tightening and clearance eliminating mechanism, and can only realize simple hooking or fixing, and can not apply continuous pressing force to the splicing surfaces of the boxes, so that assembly clearances are easy to exist among the boxes, and the overall flatness of the display screen and the picture display effect are affected. Secondly, in terms of angle adjustment and maintenance, the existing arc-shaped locks mostly adopt bolt fastening or rely on friction force of contact surfaces to fix the relative angle between the box bodies. The mode lacks a reliable mechanical engagement limiting structure, when the mode is subjected to vibration or external force, relative sliding or angle deviation is easy to occur, and long-term stability and accuracy of splicing radian are difficult to ensure. In addition, in terms of convenience of operation, the conventional locking and adjusting mechanism is generally complicated in structure, and relies heavily on auxiliary tools (such as a wrench, a screwdriver, etc.) for locking or angle adjustment. The field constructor needs to carry out loaded down with trivial details instrument operation in installation or dismantlement process, and locking and regulation step often mutually independent, can't realize quick freehand operation, has reduced the efficiency that the display screen was assembled on site and was maintained. Disclosure of Invention Aiming at the defects of the prior art, the invention provides an arc lock capable of adjusting the gap of an LED display screen box body, and aims to solve the technical problems that in the prior art, a connecting device is difficult to effectively eliminate an axial assembly gap to influence the flatness of a splicing surface, the angle adjustment locking lacks a mechanical limiting structure to cause relative offset easily, and the installation and adjustment process depends on auxiliary tools to cause low construction efficiency. In order to achieve the above purpose, the invention is realized by the following technical scheme: The utility model provides an adjustable LED display screen box clearance's arc lock, includes lock seat one and lock seat two, the inboard sliding connection of lock seat one has lock core one, the inboard sliding connection of lock seat two has lock core two, the middle part of lock core one is provided with locking subassembly, the side fixed mounting of lock core one has fixed subassembly. Preferably, the locking assembly comprises a clamping column, the clamping column is arranged in the middle of the first lock cylinder and the second lock cylinder, a sliding groove is formed in the clamping column along the axial direction, a pin is connected to the sliding groove in a sliding mode, a first spring is sleeved on the pin, and the outer portion of the first spring is abutted to the inner wall of the sliding groove. Preferably, the pin is connected with a clamping block in a rotating way, the clamping block is connected with a slot in the middle of the clamping column in a rotating way, the pin and the clamping block form linkage fit, and when the pin moves, the pin can drive the clamping block to open and be clamped with the second lock cylinder to realize axial connection. Preferably, a nut is connected to the outer side of the clamping column in a threaded manner, the nut is located on one side of the first lock cylinder and is in contact with the surface of the first lock cylinder, a second lock hole is formed in the first lock cylinder, the clamping column penetrates through the second lock hole, a first lock hole is formed in the second lock cylinder, and the bottom end of the clamping column is inserted into the first lock hole. The first surface of the lock cylinder is tightly pressed by rotating the nut, and the axial clearance can be adjusted and eliminated by matching with the tensioning of the clamping block to the second lock cylinder. Preferably, the fixing componen
