In one embodiment, as shown in fig. 2 to 8, the present invention provides a display screen, the display screen includes a box 2, a module 3 and at least two locking devices 1 as described in any one of the above embodiments, the locking devices 1 are used to lock the module 3 on the box 2.

As shown in fig. 3 and 6, the upper surface of the module 3 is provided with a groove 31, one end of the groove 31 is a semi-ellipse 311, and the end connected with the semi-ellipse 311 is a plane 312.

As shown in fig. 1 and 2, the locking device 1 includes a first member 11 and a second member 12, the first member 11 is fixed on the housing 2, the second member 12 is fixed on the module 3, the first member 11 is rotatably and movably locked on the second member 12, and the module 3 is locked on the housing 2 through the first member 11 and the second member 12.

As shown in fig. 6, the second part 12 includes a blocking module 121, and the blocking module 121 is fixed to the module. Specifically, the blocking module 121 is fixed at the side of the groove 31, and forms a locking space with the groove 31; the first member 11 is rotated and movably latched in the locking space.

Preferably, the blocking module 121 is fixedly connected with the module 3 through a screw 5.

Preferably, the blocking module 121 is a blocking plate or a blocking spring.

As shown in fig. 4, the first component 11 includes a wrenching module 111, a base 112, and a locking module 113; the base 112 is fixed on the box body 2, and specifically, the base 112 is fixed on the side of the box body 2.

The pulling module 111 is fixed on the base 112 by the locking module 113. The wrench module 111 includes a central shaft 1111, a distal shaft 1112, and a wrench end 1113; the central shaft 1111 is fixed on the base 112 by the locking module 113, and the distal shaft 1112 is rotated around the central shaft 1111 by pulling the wrench end 1113, can be accommodated in the blocking module 121 and the groove 31 of the module 3 to form the locking space, and is movably locked on the blocking module 121, thereby locking the module 3 on the housing 2.

Further, the distance from the top of the upper surface of the module 31 to the central axis 1111 of the half ellipse of the groove 31 is slightly smaller than the radius of the distal shaft 1112 during circular motion, so that the distal shaft 1112 will press the half ellipse end of the groove 31 to jack up the module 3 when disengaging from the locking space, thereby providing the pushing-out function for the locking device.

In this embodiment, through locking device will the module locking is in on the box, locking device's base is fixed on the box, and the center pin passes through locking module to be fixed on the base, be provided with half oval-shaped recess on the module, it fixes to hinder the shelves module the recess side and the recess forms locking space, distal end axle can hold in locking space, through distal end axle with the cooperation in locking space will the module locking is in on the box for locking device possesses locking and release function simultaneously, satisfies under the locking function prerequisite, possesses release function simultaneously, solves the very hard difficult problem when module locking and dismantlement simultaneously, simple structure, and is safe, economical and practical.

A display screen, when specifically using, will at least two base 112 is fixed respectively on the both sides of box 2, will pull module 111 the center pin 1111 passes through locking module 113 is fixed on base 112, will block shelves module 121 fix on module 3 and with module 3 forms a locking space.

As shown in fig. 2 and 3, when a module 3 needs to be locked and installed in a corresponding box 2, the module 3 is first placed beside the box 2, the wrench end 1113 of the wrench module 111 is pulled downward, the wrench end 1113 is rotated downward around the central shaft 1111, so that the distal shaft 1112 makes a circular motion and extends into the locking space formed by the blocking module 121 and the module 3 along the half ellipse of the groove 31, and the module 3 is locked with the box 2 by the cooperation of the distal shaft 1112 and the locking space. Fig. 7 and 8 are schematic views showing the case and the module in a locked state.

As shown in fig. 7 and 8, when the wrench end 1113 of the wrench module 111 is pulled upward when the module 3 needs to be detached from the locked box 2, the wrench end 1113 rotates upward around the central shaft 1111, so that the distal shaft 1112 moves circularly and disengages from the locking space, since the locking space formed by the module 3 and the blocking module 121 is a semi-elliptical groove 31, and the distance from the top of the upper surface of the module 3 to the central shaft 1111 of the semi-ellipse of the groove 31 is slightly smaller than the moving radius of the distal shaft 1112 during the circular motion, the distal shaft 1112 will press the semi-ellipse of the groove 31 to cause the blocking of the disengagement when the module 3 disengages from the locking space, at this time, the wrench end 1113 is pulled further, the distal shaft 1112 will press the semi-ellipse of the guide groove 31 to lift up the module 3, when the blocking module 121 cannot cover the distal shaft 1112, the distal shaft 1112 is disengaged from the locking space, thereby separating the module 3 from the housing 2, so that the module 3 can be removed. As shown in fig. 2 and 3, the box body and the module are in a disassembled state.
