[0006] When the positioning member in this application needs to be used, drive the first end to move out of the mounting hole until the first end extends out of the mounting hole. At this time, the positioning member can be used for positioning; when the positioning member in this application does not need to be used, drive the first end to move into the mounting hole until the first end retracts into the mounting hole. At this time, the positioning member will retract into the mounting hole. The positioning member in this application adopts a telescopic design, which can not only extend out of the mounting hole for positioning use, but also retract into the mounting hole, effectively protecting the positioning member from damage and extending the service life of the positioning member.

[0044] As described in the background art, currently, some display screens are formed by splicing multiple display screen bodies. In the related art, a positioning pin protruding from one of two adjacent display screen bodies is fixedly installed, and a positioning hole is provided on the other display screen body. The two adjacent display screen bodies are positioned by inserting the positioning pin into the positioning hole. However, the design in which the positioning pin protrudes and is fixedly installed on the display screen body is likely to cause damage to the positioning pin, thereby affecting the use.

[0045] Referring to Figures 1 to 8 , to solve the above problems, according to one aspect of the present application, an embodiment of the present application provides a positioning mechanism. The positioning mechanism includes a mounting member 100 and a positioning member 200. Among them, a mounting hole 110 is provided on the mounting member 100, and the extending direction of the mounting hole 110 is the first preset direction; the positioning member 200 is inserted into the mounting hole 110 and can slide in the mounting hole 110 along the first preset direction. The positioning member 200 has a first end 210, and the first end 210 can extend out of the mounting hole 110 and can retract into the mounting hole 110.

[0046] In the embodiment of the present application, the positioning mechanism is used to position two components to be positioned. The positioning mechanism is mounted on one of the two components to be positioned through the mounting member 100, and a positioning hole for inserting the positioning member 200 is provided on the other component to be positioned. The two components to be positioned are positioned by inserting the positioning member 200 into the positioning hole. The mounting member 100 is usually a mounting block and is made of aluminum to reduce the weight; the positioning member 200 is usually a positioning pin or a positioning rod and is made of iron. The length direction of the positioning member 200 is usually parallel to the first preset direction. In addition, to facilitate the installation of the positioning mechanism on the component to be positioned, the mounting member 100 and the component to be positioned are an integral part.

[0047] When the positioning member 200 in the present application needs to be used, drive the first end 210 to move out of the mounting hole 110 until the first end 210 extends out of the mounting hole 110. At this time, the positioning member 200 can be used for positioning; when the positioning member 200 in the present application does not need to be used, drive the first end 210 to move into the mounting hole 110 until the first end 210 retracts into the mounting hole 110. At this time, the positioning member 200 will retract into the mounting hole 110. The positioning member 200 in the present application adopts a telescopic design, which can not only extend out of the mounting hole 110 for positioning use, but also retract into the mounting hole 110, effectively protecting the positioning member 200 from damage and extending the service life of the positioning member 200. At the same time, the telescopic design of the positioning member 200 can also effectively reduce the overall height of the positioning mechanism, improve the space utilization rate, and improve the appearance of the positioning mechanism, making it more beautiful and concise.

[0048] Referring to Figures 1 to 8, in one embodiment, the positioning mechanism further includes a limiting member 300, which is installed on the mounting member 100 and can limit the sliding of the positioning member 200 in the mounting hole 110; the positioning member 200 has an extended position and a retracted position. When the positioning member 200 is in the extended position, the first end 210 extends out of the mounting hole 110, and the limiting member 300 restricts the first end 210 from moving towards the inside of the mounting hole 110; when the positioning member 200 is in the retracted position, the first end 210 retracts into the mounting hole 110, and the limiting member 300 restricts the first end 210 from moving towards the outside of the mounting hole 110.

[0049] In this embodiment, the limiting member 300 can be a clamping structure with two chucks. The positioning member 200 is located between the two chucks. The two chucks can simultaneously approach the positioning member 200 to clamp and fix the positioning member 200, and can simultaneously move away from the positioning member 200 to separate from the positioning member 200. At the same time, the two chucks can achieve synchronous movement by using a screw rod assembly. Figure 1 in which the positioning member 200 is in the extended position, Figure 5 the positioning member 200 in is in the extended position, Figure 6 the positioning member 200 in is in the extended position. In other embodiments, the limiting member 300 can also be installed on the positioning member 200.

[0050] When the positioning member 200 in this application needs to be used, drive the first end 210 to move out of the mounting hole 110. After the first end 210 extends out of the mounting hole 110, use the limiting member 300 to limit the sliding of the positioning member 200 in the mounting hole 110. At this time, the positioning member 200 can be used for positioning; when the positioning member 200 in this application does not need to be used, drive the first end 210 to move into the mounting hole 110. After the first end 210 retracts into the mounting hole 110, use the limiting member 300 to limit the sliding of the positioning member 200 in the mounting hole 110. At this time, the positioning member 200 will retract into the mounting hole 110. The provided limiting member 300 plays a role in restricting the movement of the positioning member 200, enabling the positioning member 200 to stably stay in the extended position and the retracted position.

[0051] Refer to Figure 2 、 Figure 3 and Figure 6 , in one embodiment, the limiting member 300 includes a first limiting body 310, and a first limiting groove 220 is provided on the positioning member 200; when the positioning member 200 is in the extended position, the limiting member 300 restricts the first end 210 from moving towards the inside of the mounting hole 110 by inserting the first limiting body 310 into the first limiting groove 220.

[0052] In this embodiment, when the positioning member 200 is in the extended position, a part of the first limiting body 310 is inserted into the first limiting groove 220 and can contact the groove wall of the first limiting groove 220, and another part of the first limiting body 310 is located outside the first limiting groove 220. The first limiting body 310 can limit the movement of the first end 210 towards the inside of the mounting hole 110 by applying resistance to the groove wall of the first limiting groove 220. The provided first limiting body 310 plays a blocking role, enabling the positioning member 200 to stably stay in the extended position for positioning use.

[0053] Referring to Figure 2 , Figure 4 and Figure 7 , in one embodiment, the limiting member 300 further includes a second limiting body 320. The positioning member 200 is provided with a second limiting groove 230, and the second limiting groove 230 is located on one side of the first limiting groove 220 close to the first end 210. When the positioning member 200 is in the retracted position, the limiting member 300 limits the movement of the first end 210 towards the outside of the mounting hole 110 by inserting the second limiting body 320 into the second limiting groove 230.

[0054] In this embodiment, when the positioning member 200 is in the retracted position, a part of the second limiting body 320 is inserted into the second limiting groove 230 and can contact the groove wall of the second limiting groove 230, and another part of the second limiting body 320 is located outside the second limiting groove 230. The second limiting body 320 can limit the movement of the first end 210 towards the outside of the mounting hole 110 by applying resistance to the groove wall of the second limiting groove 230. The provided second limiting body 320 plays a blocking role, enabling the positioning member 200 to stably stay in the retracted position.

[0055] Referring to Figure 2 and Figures 6 to 8 , in one embodiment, the first limiting body 310 can slide on the mounting member 100 along a second preset direction, and there is an included angle between the second preset direction and the first preset direction. The direction from the second limiting groove 230 to the first limiting groove 220 is parallel to the first preset direction, and the second limiting groove 230 communicates with the first limiting groove 220. The groove wall of the second limiting groove 230 can block the first limiting body 310 from entering the second limiting groove 230. When the positioning member 200 is in the retracted position, the limiting member 300 limits the movement of the positioning member 200 through the frictional force between the second limiting body 320 and the groove wall of the second limiting groove 230. The second limiting body 320 can switch between the first limiting groove 220 and the second limiting groove 230. During the process of the positioning member 200 switching from the extended position to the retracted position, the first limiting body 310 is withdrawn from the first limiting groove 220 along the second preset direction, and the second limiting body 320 enters the second limiting groove 230 from the first limiting groove 220.

[0056] In this embodiment, the first limiting body 310 can slide on the mounting member 100 by relying on a guide rail or a sleeve. At the same time, the second preset direction is usually perpendicular to the first preset direction, so as to facilitate the manufacturing and processing of the positioning mechanism. The diameter of the part of the first limiting body 310 that can be inserted into the first limiting groove 220 is less than or equal to the groove diameter of the first limiting groove 220, and the diameter of the part of the first limiting body 310 that can be inserted into the first limiting groove 220 is greater than the groove diameter of the second limiting groove 230, so that the groove wall of the second limiting groove 230 can prevent the first limiting body 310 from entering the second limiting groove 230; the diameter of the part of the second limiting body 320 that can be inserted into the first limiting groove 220 or the second limiting groove 230 is less than the diameter of the first limiting body 310, and the diameter of the part of the second limiting body 320 that can be inserted into the first limiting groove 220 or the second limiting groove 230 is equal to the groove diameter of the second limiting groove 230, so that after the second limiting body 320 is inserted into the second limiting groove 230, the second limiting body 320 remains in contact with the groove wall of the second limiting groove 230, thereby generating a frictional force, and further restricting the positioning member 200 from sliding along the first preset direction; at the same time, the first limiting body 310 may be provided with an insertion hole for the second limiting body 320 to be inserted, so that the first limiting body 310 and the second limiting body 320 can be located in the first limiting groove 220 at the same time. In addition, the second limiting groove 230 is usually located above the first limiting groove 220, and the first end 210 is usually located above the second limiting groove 230. In other embodiments, the second limiting groove 230 may also be located below the first limiting groove 220, and the first end 210 is located below the second limiting groove 230.

[0057] When the positioning member 200 in the present application needs to be switched from the extended position to the retracted position, first drive the first limiting body 310 to be withdrawn from the first limiting groove 220 along the second preset direction. At this time, the first end 210 can be retracted into the mounting hole 110 under the action of the self-weight of the positioning member 200 or an external thrust; along with the movement of the positioning member 200, since the first limiting groove 220 and the second limiting groove 230 are communicated, the second limiting body 320 will also enter the second limiting groove 230 from the first limiting groove 220; after the second limiting body 320 enters the second limiting groove 230, the second limiting body 320 restricts the first end 210 from moving outward toward the outside of the mounting hole 110 by the frictional force between it and the groove wall of the second limiting groove 230, and at the same time, it will also restrict the first end 210 from continuing to move inward toward the mounting hole 110, so that the positioning member 200 can stay stably at the retracted position.

[0058] When the positioning member 200 in this application needs to switch from the retracted position to the extended position, first, a thrust force that can overcome the frictional force between the second limiting body 320 and the groove wall of the second limiting groove 230 is applied to the positioning member 200, and the direction of the thrust force is opposite to the direction of the frictional force. Along with the movement of the positioning member 200, the second limiting body 320 will enter the first limiting groove 220 from the second limiting groove 230, and at the same time, the first limiting body 310 will also slide into the first limiting groove 220 along the second preset direction, so that the positioning member 200 can stably stay at the extended position. The above design can not only make the positioning member 200 extend outside the mounting hole 110 and retract into the mounting hole 110, but also improve the switching efficiency of the positioning member 200 between the extended position and the retracted position. In addition, to enable the first end 210 to be completely retracted into the mounting hole 110, the groove length of the second limiting groove 230 is greater than the diameter of the partial structure of the second limiting body 320 that can be inserted into the first limiting groove 220 or the second limiting groove 230.

[0059] Referring to Figure 6 and Figure 7 , in an embodiment, the second limiting body 320 is connected to the first limiting body 310. The above design effectively reduces the possibility of loss that is likely to occur due to the independent setting of the first limiting body 310 and the second limiting body 320.

[0060] Referring to Figure 6 and Figure 7 , in an embodiment, the second limiting body 320 has a screw 321, and a threaded hole is provided on the first limiting body 310. The screw 321 is inserted into the threaded hole and is in threaded cooperation with the threaded hole.

[0061] In this embodiment, the first limiting body 310 has a connecting rod 311, and the threaded hole is provided on the connecting rod 311; the diameter of the connecting rod 311 is greater than the groove diameter of the second limiting groove 230, the diameter of the screw 321 is smaller than the diameter of the connecting rod 311 and is equal to the groove diameter of the second limiting groove 230, and is smaller than the groove length of the second limiting groove 230. When the positioning member 200 is in the extended position, the connecting rod 311 is located in the first limiting groove 220, and at the same time, a partial structure of the screw 321 is located in the first limiting groove 220; when the positioning member 200 is in the retracted position, the connecting rod 311 is located outside the first limiting groove 220, and at the same time, the screw 321 is located in the second limiting groove 230. The above design improves the convenience of connecting the first limiting body 310 and the second limiting body 320. In other embodiments, the first limiting body 310 and the second limiting body 320 can also be connected by fasteners such as connecting screws or connecting bolts.

[0062] Referring to Figure 1 , Figure 2 and Figures 6 to 8, in one embodiment, the mounting member 100 is provided with a sliding hole 120 which communicates with the mounting hole 110. The first limiting body 310 is installed in the sliding hole 120 and can slide in the sliding hole 120 along a second preset direction; the second limiting body 320 is installed in the sliding hole 120 and can slide in the sliding hole 120 along the second preset direction.

[0063] In this embodiment, the extending direction of the sliding hole 120 is parallel to the second preset direction. The provided sliding hole 120 not only facilitates the sliding of the first limiting body 310 and the second limiting body 320 along the second preset direction on the mounting member 100, but also plays a role in protecting the first limiting body 310 and the second limiting body 320. In addition, it also plays a role in reducing the volume of the positioning mechanism.

[0064] Refer to Figure 2 and Figures 6 to 8 , in one embodiment, a first blocking structure 121 and a second blocking structure 122 are installed at intervals in the sliding hole 120 along the second preset direction, and the mounting hole 110 is located between the first blocking structure 121 and the second blocking structure 122; the first limiting body 310 has a first limiting cap 312, and the first blocking structure 121 is used to block the first limiting cap 312 from entering the mounting hole 110; the second limiting body 320 has a second limiting cap 322, and the second blocking structure 122 is used to block the second limiting cap 322 from entering the mounting hole 110; the limiting member 300 further includes an elastic reset body 330, the elastic reset body 330 is located between the second blocking structure 122 and the second limiting cap 322, and the two opposite ends of the elastic reset body 330 are respectively in contact with the second blocking structure 122 and the second limiting cap 322; when the positioning member 200 is in the extended position, the elastic reset body 330 is in a natural extended state, and the second limiting cap 322 is located outside the sliding hole 120; when the positioning member 200 is in the retracted position, the elastic reset body 330 is in a compressed state.

[0065] In this embodiment, the first blocking structure 121 is a first blocking ring. The first blocking ring is fixedly installed on the inner wall of the sliding hole 120 along the circumferential direction of the sliding hole 120. The connecting rod 311 can pass through the first blocking ring and then be inserted into the first limiting groove 220 or the second limiting groove 230. The second blocking structure 122 is a second blocking ring. The second blocking ring is fixedly installed on the inner wall of the sliding hole 120 along the circumferential direction of the sliding hole 120. The screw rod 321 can pass through the second blocking ring and then be inserted into the first limiting groove 220. The first blocking structure 121 and the second blocking structure 122 used in cooperation in this application play a blocking role, preventing the first limiting body 310 and the second limiting body 320 from sliding out of the sliding hole 120. The elastic reset body 330 is a reset spring. The reset spring is sleeved on the screw rod 321. In other embodiments, the reset spring can also be located on one side of the screw rod 321 and inside the sliding hole 120.

[0066] When the positioning member 200 in this application needs to be switched from the extended position to the retracted position, since the second limiting cap 322 is located outside the sliding hole 120, more parts of the second limiting body 320 can be pushed into the first limiting groove 220 by pushing the second limiting cap 322, and at the same time, the first limiting body 310 is completely pushed out of the first limiting groove 220. During this process, the elastic reset body 330 will be in a compressed state under the extrusion of the second limiting cap 322. Along with the movement of the positioning member 200, the second limiting body 320 will enter the second limiting groove 230 from the first limiting groove 220. After the second limiting body 320 enters the second limiting groove 230, the second limiting body 320 will rely on the friction force between it and the groove wall of the second limiting groove 230 to limit the first end 210 from moving outward relative to the mounting hole 110, and at the same time, it will also limit the first end 210 from continuing to move inward relative to the mounting hole 110, so that the positioning member 200 can stably stay at the retracted position.

[0067] When the positioning member 200 in this application needs to be switched from the retracted position to the extended position, first, a thrust force that can overcome the friction force between the second limiting body 320 and the groove wall of the second limiting groove 230 is applied to the positioning member 200. The direction of the thrust force is opposite to the direction of the friction force. Along with the movement of the positioning member 200, the second limiting body 320 will enter the first limiting groove 220 from the second limiting groove 230. At this time, the second limiting body 320 will no longer be restricted by the friction force between it and the groove wall of the second limiting groove 230. The second limiting cap 322 will drive the first limiting body 310 to move into the first limiting groove 220 under the action of the reset thrust force applied by the elastic reset body 330. The positioning member 200 will also stably stay at the extended position under the cooperation of the first limiting body 310 and the first limiting groove 220. The provided elastic reset body 330 can drive the first limiting body 310 to be inserted into the first limiting groove 220, so that the positioning member 200 can stably stay at the extended position, playing a reset role.

[0068] Referring to Figure 4 and Figure 7 In one embodiment, the positioning member 200 further has a second end 240, which is disposed opposite to the first end 210. When the positioning member 200 is in the retracted position, the second end 240 of the positioning member 200 is located outside the mounting hole 110. The above design is beneficial to pushing the positioning member 200 to switch from the retracted position to the extended position, improving the convenience of the switching operation.

[0069] Referring to Figure 1 , Figure 2 and Figure 6 In one embodiment, a clamping member 400 is mounted on the mounting member 100. The clamping member 400 can undergo elastic deformation and has a clamping space 410 capable of clamping an object.

[0070] In this embodiment, the clamping member 400 is a snap ring. An installation groove 130 is provided on the surface of the installation member 100, and a movable groove 140 is provided on the groove wall of the installation groove 130. A part of the structure of the clamping member 400 is embedded in the movable groove 140 and can move within the movable groove 140. The clamping space 410 is located within the installation groove 130. The provided clamping member 400 can clamp cables such as power cables or network cables, playing a role in organizing and fixing the cables and avoiding interference between the cables. In other embodiments, the clamping member 400 can also be an elastic ring, an expansion ring, or a rubber ring made of rubber or silica gel.

[0071] Referring to Figures 1 to 8 According to another aspect of the present application, an embodiment of the present application further provides a display screen. The display screen includes a plurality of display screen bodies and the above-mentioned positioning mechanism. The positioning mechanism is installed on one of the adjacent two display screen bodies, and a positioning hole is provided on the other display screen body. The adjacent two display screen bodies are positioned by inserting the positioning member 200 into the positioning hole.

[0072] In the embodiment of the present application, the display screen is usually an LED display screen (the full English name of LED: Light Emitting Diode, Chinese name: Light Emitting Diode). The positioning mechanism is fixedly installed on one of the adjacent two display screen bodies through the installation member 100, and the installation member 100 and the display screen body are an integral part. The provided positioning mechanism is beneficial to positioning the adjacent two display screen bodies, improving the convenience of connecting the two display screen bodies.

[0073] In summary, implementing the positioning mechanism and display screen provided in this embodiment has at least the following beneficial technical effects: When the positioning member 200 in this application needs to be used, it drives the first end 210 to move outward from the mounting hole 110 until the first end 210 extends out of the mounting hole 110. At this time, the positioning member 200 can be used for positioning; when the positioning member 200 in this application does not need to be used, it drives the first end 210 to move into the mounting hole 110 until the first end 210 retracts into the mounting hole 110. At this time, the positioning member 200 will retract into the mounting hole 110. The positioning member 200 in this application adopts a telescopic design, which can not only extend out of the mounting hole 110 for positioning use, but also retract into the mounting hole 110, effectively protecting the positioning member 200 from damage and extending the service life of the positioning member 200. At the same time, the telescopic design of the positioning member 200 can also effectively reduce the overall height of the positioning mechanism, improve the space utilization rate, and improve the appearance of the positioning mechanism, making it more beautiful and concise.

[0074] The above are only the preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of this application shall be included in the protection scope of this application.
