Fig. 9 is a schematic structural view of the slide rail 22 shown in fig. 8. Fig. 10 is an exploded view of the slide rail 22 shown in fig. 9.

In this embodiment, the slide rail 22 may include a rail, a first stopper 221, and a second stopper 222. The track may include a main sliding groove 223, a first sliding groove 224 and a second sliding groove 225, the main sliding groove 223 is located between the first sliding groove 224 and the second sliding groove 225, and the first sliding groove 224 and the second sliding groove 225 are disposed opposite to each other. The first stopper 221 is slidably connected to the first sliding groove 224, and the second stopper 222 is slidably connected to the second sliding groove 225. The first stopper 221 and the second stopper 222 may each include a locking bolt 2211, and both are fixedly connected to the slider 23 through the locking bolt 2211, so as to mount the slider 23 to the main chute 223. When the locking bolts 2211 of the first stopper 221 and the second stopper 222 are locked, the sliding block 23 contacts with the side walls on both sides of the main sliding groove 223, so that the sliding block 23 can slide relative to the main sliding groove 223 along with the sliding of the first stopper 221 and the second stopper 222. The bottom wall of the slide rail 22 is provided with a mounting hole 226. The slide rail 22 may be bolted to the support platform via mounting holes 226 with bolts to secure the slide rail 22.

In some embodiments, the groove wall of the first sliding groove 224 and the first stopper 221 form a first stopper structure. The groove wall of the second sliding groove 225 and the second stopper 222 form a second stopper structure. The first limiting structure and the second limiting structure respectively limit the first limiting block 221 and the second limiting block 222 to be away from the main sliding groove 223.

It is understood that the first limiting structure and the second limiting structure in the present embodiment have the same structure, and the first limiting structure is taken as an example for description below. The first sliding slot 224 has a first opening 2241 and a second opening 2242, which are oppositely disposed, the first opening 2241 is located on one side of the first sliding slot 224 close to the sliding block 23, and the second opening 2242 is located on one side of the first sliding slot 224 away from the sliding block 23. The locking bolt 2211 of the first stopper 221 passes through the first stopper 221 and is connected to the surface of the slider 23 on the side close to the first opening 2241 through the first opening 2241.

Illustratively, as shown in fig. 11, the first and second retention structures are each wedge-shaped mating structures. Taking the first position-limiting structure as an example, the area of the first opening 2241 is smaller than the area of the second opening 2242, and the slot wall of the first sliding slot 224 smoothly connects the first opening 2241 and the second opening 2242 to form a wedge-shaped matching structure. When the locking bolt 2211 is locked, the first limiting block 221 moves towards the direction close to the main sliding groove 223 relative to the first sliding groove 224, and at the moment, a gap between the first limiting block 221 and the first sliding groove 224 is eliminated, so that the first limiting block 221 and the first sliding groove 224 are connected more tightly, and the reliability of the whole structure is higher.

It can be understood that when the user adjusts the position and/or the orientation of the screen, the first stopper 221 and the second stopper 222 slide relative to the first sliding slot 224 and the second sliding slot 225, respectively, and drive the sliding block 23 to slide relative to the main sliding slot 223, so as to compensate the distance between the adjusting assemblies 20. However, in the manufacturing process, a certain gap exists between the first stopper 221 and the first sliding groove 224, and a certain gap also exists between the second stopper 222 and the second sliding groove 225, so that the first stopper 221 and/or the second stopper 222 are easily away from the main sliding groove 223 in the sliding process, and thus an error is generated in the movement of the slider 23. When the movement of the slider 23 is reflected to the support platform 10 through the telescopic member 21, the movement error of the slider 23 is further amplified due to the long length of the force arm between the two, so that the adjustment error of the position and/or orientation of the screen adjustment by the end user is further increased, and the user experience is affected. And the screen adjusting device 100 of this application is through setting up first limit structure and second limit structure, and set up the two to wedge cooperation structure, through locking bolt 2211 link block 23, make the space between first stopper 221 and first spout 224 and the space between second stopper 222 and the second spout 225 can eliminate through locking bolt 2211's locking, the reliability of whole adjusting part 20 has been improved, reduce the error when slider 23 slides with main spout 223 simultaneously, thereby make the regulation to screen position and/or orientation more accurate, improve user's use and experience.

In some embodiments, the first and second stop structures may also be step-fit structures (as shown in fig. 12). At this time, the first opening 2241 and the second opening 2242 are connected by a groove wall of the first sliding groove 224, and the groove wall has a step structure 2243. Of course, in other embodiments, the first limiting structure and the second limiting structure may also be other types of limiting structures, which is not limited in this application.

In some embodiments, the two ends of the groove walls of the main sliding groove 223 may be provided with ribs 227, and each rib 227 connects the bottom wall of the sliding rail 22 and the side wall of one side of the main sliding groove 223. When the first stopper 221 and/or the second stopper 222 are locked by the locking bolt 2211, since the first stopper and the second stopper are both wedge-shaped fitting structures, the sidewalls of the two sides of the main sliding groove 223 may incline toward the center of the main sliding groove 223 along with the locking of the locking bolt 2211, so that the structure of the slide rail 22 is deformed. And this application has strengthened slide rail 22's structural reliability through set up a plurality of floor 227 at main spout 223, avoids producing the deformation, has effectively improved the life of product. Of course, in other embodiments, the slide rail 22 may also be provided with other structures to improve the structural stability and reliability of the slide rail 22. This is not a limitation of the present application.
