In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

In one embodiment, a splicing lock is provided for splicing the cabinets of two adjacent display modules in a display screen. As shown in FIGS. 1 to 3 , the splicing lock includes a first installation body 1 , a connecting piece 2 and a second installation body 3 . The first installation body 1 has a first through hole 11 , and one end of the first through hole 11 has a tapered portion 12 . The connector 2 is movably disposed in the first through hole 11 , and includes a head 21 , a rod 22 and a first threaded portion 23 which are sequentially connected. The head 21 has a tapered surface 24 matching with the tapered portion 12 . The second mounting body 3 has a second through hole 31 aligned with the first through hole 11 , and an end of the second through hole 31 away from the first through hole 11 is provided with a second threaded portion 32 matched with the first threaded portion 23 . Wherein, the first mounting body 1 and the second mounting body 3 are respectively arranged on the boxes of two display modules adjacent to the display screen, and the connector 2 is arranged in the first through hole 11 and along the first through hole 11. The length direction can be moved, the second installation body 3 is provided with a second through hole 31 aligned with the first through hole 11, the connecting piece 2 partially extends into the first through hole 11, and partly passes through the first through hole 11 Extend into the second through hole 31 and cooperate with the second through hole 31 to realize the connection between the first mounting body 1 and the second mounting body 3, and then realize the two mounting bodies respectively provided with the first mounting body 1 and the second mounting body 3. Box splicing.

Specifically, the end of the first through hole 11 away from the second through hole 31, that is, the end of the first through hole 11 close to the head 21 has a tapered portion 12, and the head 21 has a tapered portion that matches the tapered portion 12. On the surface 24 , the end of the second through hole 31 away from the first through hole 11 has a second threaded portion 32 matched with the first threaded portion 23 . When the two boxes are spliced together, the first threaded part 23 and part of the rod part 22 of the connector 2 extend into the second through hole 31, and the connector 2 is rotated so that the first threaded part 23 and the second threaded part 32 cooperate, and at the same time pass The mutual resistance of the tapered surface 24 and the tapered portion 12 makes the connecting piece 2 move along its radial direction and drives the second mounting body 3 to move synchronously, so that the first mounting body 1 and the second mounting body 3 are aligned, thereby making the The two cabinets respectively installed with the first mounting body 1 and the second mounting body 3 are aligned to improve splicing accuracy of the two cabinets.

The taper range of the tapered surface 24 is not unique. In one embodiment, the taper of the tapered surface 24 is 30°-70°.

The travel of the lengthwise movement of the hole 11 prevents the connecting piece 2 from falling off from the first through hole 11 at the same time, and prevents the connecting piece 2 from falling into the box during the splicing of the two boxes and causing the display module to malfunction.

Further, in one embodiment, as shown in FIG. 3 , the end of the positioning member 4 close to the connecting member 2 has a blind hole 41, and a positioning bead 42 is arranged in the blind hole 41, and a part of the positioning bead 42 extends out of the blind hole 41 and The connecting piece 2 resists, and an elastic member 43 is provided in the blind hole 41 to drive the positioning bead 42 to keep abutting against the connecting piece 2 . Wherein, one end of the opposite ends of the elastic member 43 in the telescopic direction is abutted against the bottom surface of the blind hole 41, and the other end is abutted against the positioning bead 42, so that the positioning bead 42 is kept against the connecting piece by the elasticity provided by the elastic member 43. 2, while preventing excessive friction between the positioning part 4 and the connecting part 2 from causing damage to the connecting part 2.

In one embodiment, the diameter of the rod portion 22 is larger than the diameter of the first threaded portion 23 , and the size of the second through hole 31 is adapted to the rod portion 22 . As shown in Figure 4, after the first threaded part 23 and the second threaded part 32 cooperate, part of the rod part 22 extends into the second through hole 31, the diameter of the rod part 22 is larger than the diameter of the first threaded part 23, and the second through hole The size of the hole 31 is adapted to the rod portion 22 , so that the alignment accuracy of the two boxes can be further improved through the cooperation of the rod portion 22 and the second through hole 31 .

In one embodiment, a display screen is also provided. As shown in FIG. 1 to FIG. 4 , the display screen includes a first box body 5 and a second box body 6 , and also includes the aforementioned splicing lock. The first installation body 1 is arranged on the first box body 5 , and the second installation body 3 is arranged on the second box body 6 . Wherein, the first installation body 1 and the connector 2 are provided on the first box body 5, the first installation body 1 is arranged on the inner side of the first box body 5, and the first through hole 11 is provided through the first box body 5, so as to The connecting piece 2 can partially protrude out of the first box body 5 . Further, the second mounting body 3 is disposed inside the second box body 6 , and the second through hole 31 is provided through the second box body 6 , so that the connecting member 2 can partially extend into the second box body 6 . After the first box body 5 and the second box body 6 are spliced, the first installation body 1, the connector 2 and the second installation body 3 are respectively hidden in the first box body 5 and the second box body 6, so that the appearance of the display screen can be improved. tidy.

Specifically, when splicing the first box body 5 and the second box body 6, the first installation body 1 on the first box body 5 is aligned with the second installation body 3 on the second box body 6, and the second installation body 3 is moved.
