[0041] With the continuous development of science and technology, the application of LED display screens is becoming more and more extensive. LED display screens are composed of multiple LED display boxes. In the related technology, after the traditional LED display screen is spliced, if some of the LED display boxes are damaged, the LED display boxes need to be disassembled one by one for maintenance. The maintenance process is cumbersome, the maintenance efficiency is low, and the maintenance cost is high.

[0042] Based on the above problems, the present application provides a positioning component and an LED display device, which aim to easily and quickly realize the splicing and disassembly of the LED box and improve the installation and maintenance efficiency of the LED box.

[0043] The embodiment of the first aspect of the present application provides a positioning assembly 10, such as Figures 1 to 5 As shown, the positioning assembly 10 includes a sleeve 1, a moving rod 2, an elastic member 3 and a rotating shaft 4. The sleeve 1 has a accommodating cavity 11, and the sleeve 1 extends from a first end 111 to a second end 112 along a first direction; the moving rod 2 is placed in the accommodating cavity 11 and is slidably connected to the sleeve 1, and the moving rod 2 can move linearly along the first direction, so that at least part of the moving rod 2 extends out of the sleeve 1 from the first end 111, and an arc-shaped groove 23 is provided on the side of the moving rod 2 close to the second end 112; the elastic member 3 is placed in the accommodating cavity 11 and is sleeved on the outer wall of the moving rod 2; the rotating shaft 4 is provided at the second end 112 and is at least partially placed in the accommodating cavity 11, the rotating shaft 4 abuts against the moving rod 2, and the rotating shaft 4 can rotate around the axis of the sleeve 1 to engage in or disengage from the arc-shaped groove 23.

[0044] In the present application embodiment, Figures 1 to 5 As shown, the sleeve 1 is used to provide an installation position for the elastic member 3 and the moving rod 2, and cooperates with the rotating shaft 4 and the elastic member 3 to realize the transition of the telescopic state of the moving rod 2. The sleeve 1 can also protect the elastic member 3 and the moving rod 2 and other structures, thereby improving the reliability of the positioning assembly 10. The moving rod 2 can move downward along the first direction under the pressure applied by the rotating shaft 4, extend out of the sleeve 1, and realize the positioning and fixing of the adjacent box 100. It can also retract into the sleeve 1 under the elastic force provided by the elastic member 3 when the force applied by the rotating shaft 4 is reduced or cancelled, so as to facilitate the disassembly and maintenance of the box 100. The elastic member 3 is located between the sleeve 1 and the moving rod 2. When the positioning assembly 10 positions and fixes the box 100, the moving rod 2 compresses the elastic member 3 and extends out of the sleeve 1 after being pressed; when the box 100 needs to be disassembled and maintained, the pressure on the moving rod 2 is greatly reduced or cancelled, so that the elastic member 3 is in an extended state, and the moving rod 2 automatically retracts into the sleeve 1 under the elastic force provided by the elastic member 3, so as to avoid hindering the disassembly and maintenance of the box 100.

[0045] In the embodiment of the present application, the portion where the rotating shaft 4 is engaged with the arc-shaped groove 23 may be in the shape of a plate, such as Figure 1 As shown, two arc-shaped grooves 23 that are opposite and spaced apart can be provided on the moving rod 2. When the rotating shaft 4 rotates from the bottom to the top of the arc-shaped groove 23 until it is out of the arc-shaped groove 23 and abuts against the side of the moving rod 2 close to the second end 112, the pressure applied by the rotating shaft 4 to the moving rod 2 gradually increases, so as to drive the moving rod 2 to move downward in the first direction and extend out of the sleeve 1, so as to achieve the positioning and fixation of the adjacent box 100; when the rotating shaft 4 rotates from the top to the bottom of the arc-shaped groove 23 again, the pressure applied by the rotating shaft 4 to the moving rod 2 gradually decreases or is cancelled, so that the moving rod 2 automatically retracts into the sleeve 1 under the elastic force provided by the elastic member 3, so as to achieve the disassembly and maintenance of the adjacent box 100. When the positioning assembly 10 is in a non-working state, part of the structure of the rotating shaft 4 is stuck in the bottom of the arc-shaped groove 23.

[0046] In the embodiment of the present application, the positioning assembly 10 can be applied to an LED display screen to realize the splicing and disassembly of adjacent LED boxes 100. Figure 6 As shown, when positioning and fixing adjacent boxes 100 by positioning assembly 10, maintenance personnel can first connect positioning assembly 10 with one of boxes 100, and then rotate rotating shaft 4 to make rotating shaft 4 disengage from arc groove 23. During the process of rotating shaft 4 disengaging from arc groove 23, rotating shaft 4 will squeeze arc groove 23 and thus apply pressure to moving rod 2. Driven by the pressure, moving rod 2 can slide along the first direction and gradually extend out of sleeve 1, so as to realize positioning and fixing of adjacent boxes 100. During this process, elastic member 3 is in a compressed state. Figure 8 and Fig. 9As shown, when a box 100 needs to be disassembled, the rotating shaft 4 can be rotated again to make the rotating shaft 4 re-engage the bottom of the arc groove 23. At this time, the rotating shaft 4 does not apply pressure to the moving rod 2 or applies less pressure, and the elastic member 3 is subjected to less force and gradually recovers to the initial extended state. The moving rod 2 retracts into the sleeve 1 under the elastic force provided by the elastic member 3, thereby realizing the disassembly of the adjacent box 100. The positioning assembly 10 has a simple structure, is easy to operate, and is convenient to assemble and disassemble. The telescopic state of the moving rod can be changed by rotating the rotating shaft 4, and the splicing and disassembly of the box 100 can be realized simply and quickly, thereby improving the installation and maintenance efficiency of the box. In addition, the positioning assembly 10 can be operated without relevant technical training and has high applicability.

[0047] In the embodiment of the present application, the positioning assembly 10 can also be used to disassemble and maintain a single box 100 at a specific position without affecting the installation and fixation of other boxes 100 adjacent to the box to be maintained, and it is not necessary to disassemble all boxes 100 on one side of the box to be maintained, which can greatly improve the mobility of the box 100 maintenance, improve the maintenance efficiency, and reduce the maintenance cost. Optionally, the elastic member 3 includes but is not limited to a spring, and the material of each component in the positioning assembly 10 is but is not limited to metal or plastic.

[0048] In some embodiments, the arc groove 23 may be a parabolic groove, and the arc surface where the arc groove 23 abuts against the rotating shaft 4 may be a helical surface similar to a screw thread. The parabolic groove can make the rotating member rotate more smoothly during operation, improve the stability of the linear movement of the moving rod 2, and improve the working stability of the positioning assembly 10. The helical surface can reduce the friction between the arc groove 23 and the rotating shaft 4, reduce the difficulty of rotating the rotating shaft 4, and increase the rotation rate of the rotating shaft 4, thereby increasing the moving rate of the moving rod 2 and the positioning rate of the positioning assembly 10, so as to realize the splicing and disassembly of the box 100 in a simple and fast manner, and improve the installation and maintenance efficiency of the box 100.

[0049] In some embodiments, Figure 1 and Figure 6 As shown, the arc groove 23 may also have one side that is arc-shaped and the other side that is a plane parallel to the first direction, and the arc surface may also be a spiral surface. When the box 100 is disassembled for maintenance, the rotating shaft 4 may be rotated again to retract the moving rod 2 into the sleeve 1. At this time, the rotating shaft 4 may be rotated from one side of the arc surface so that the rotating shaft 4 can be re-engaged in the arc groove 23 more smoothly, buffering the impact force received by the rotating shaft 4 when it is engaged in the limit groove 24, thereby improving the reliability of the rotating shaft 4; the rotating shaft 4 may also be rotated from one side of the plane so that the rotating shaft 4 can be re-engaged in the arc groove 23 easily and quickly, thereby increasing the retraction rate of the moving rod 2, thereby improving the installation and maintenance efficiency of the box 100.

[0050] In some embodiments, Figure 4 As shown, the first end 111 is provided with a first through hole 12 connected to the accommodating cavity 11, and along the first direction, the boundary of the orthographic projection of the first through hole 12 is located within the boundary of the orthographic projection of the accommodating cavity 11; the moving rod 2 includes a first rod segment 21 and a second rod segment 22 connected to each other, the elastic member 3 is sleeved on the first rod segment 21, the first through hole 12 is used to expose the first rod segment 21, at least part of the first rod segment 21 can pass through the first through hole 12 and extend out of the sleeve 1, the second rod segment 22 is provided with an arc groove 23, and along the first direction, the boundary of the orthographic projection of the first rod segment 21 is located within the boundary of the orthographic projection of the second rod segment 22.

[0051] In the present application embodiment, Figure 4 As shown, the elastic member 3 is sleeved on the first rod segment 21, and along the first direction, the boundary of the orthographic projection of the first through hole 12 is located within the boundary of the orthographic projection of the accommodating cavity 11, that is, the inner diameter of the first through hole 12 is smaller than the inner diameter of the accommodating cavity 11; the boundary of the orthographic projection of the first rod segment 21 is located within the boundary of the orthographic projection of the second rod segment 22, that is, the outer diameter of the second rod segment 22 is larger than the outer diameter of the first rod segment 21. Without affecting the extension or retraction of the first rod segment 21 into the sleeve 1, the aforementioned size setting can limit the elastic member 3 between the second rod segment 22 and the sleeve 1, prevent the elastic member 3 from escaping from the accommodating cavity 11, and allow the elastic member 3 to be compressed or restored to the initial extended state along the first direction, thereby providing elastic force to drive the moving rod 2 to move during the process of restoring the initial extended state, so that the moving rod 2 can quickly retract into the accommodating cavity 11, thereby releasing the positioning and fixing between adjacent boxes 100, and improving the maintenance efficiency of the boxes 100.

[0052] In some embodiments, Figure 1 As shown, the positioning assembly 10 further includes a first engaging assembly 5, which includes a first protrusion 51 and a first groove 52 that engage with each other; the first protrusion 51 is arranged on the outer wall of the second rod segment 22, and the first groove 52 is arranged on the inner wall of the sleeve 1; or the first protrusion 51 is arranged on the inner wall of the sleeve 1, and the first groove 52 is arranged on the outer wall of the second rod segment 22. The first engaging assembly 5 is used to realize the engagement between the sleeve 1 and the moving rod 2 and to limit the moving direction of the moving rod 2. When the rotating shaft 4 rotates to squeeze the arc-shaped groove 23 and applies pressure to the moving rod 2, the sleeve 1 also applies a force in a different direction to the moving rod 2 through the first engaging assembly 5, so that the moving rod 2 moves linearly along the first direction under the combined force of the rotating shaft and the sleeve 1, and the sliding of the moving rod 2 in the sleeve 1 is realized, thereby extending or retracting the sleeve 1, and realizing the positioning, fixing or disassembly and maintenance of the adjacent box 100.

[0053] In some embodiments, Fig.10As shown, the rotating shaft 4 includes a first shaft segment 41, a second shaft segment 42 and a second protrusion 43 connected to each other. The first shaft segment 41 can be inserted into or out of the arc groove 23. The second shaft segment 42 is arranged on the side of the first shaft segment 41 away from the moving rod 2. The second protrusion 43 is located between the first shaft segment 41 and the second shaft segment 42. Along the first direction, the boundary of the orthographic projection of the first shaft segment 41 and the second shaft segment 42 is located within the boundary of the orthographic projection of the second protrusion 43. The second protrusion 43 can be an annular protrusion, and the second protrusion 43 is arranged radially around the first shaft segment 41 and / or the second shaft segment 42. The second protrusion 43 and the first shaft segment 41 are placed in the accommodating chamber 11 so as to abut against the arc groove 23. The second shaft segment 42 is at least partially placed outside the accommodating chamber 11 so as to facilitate the maintenance personnel to drive the rotating shaft to rotate, thereby extending or retracting the sleeve 1 of the moving rod 2, so as to achieve the positioning, fixing or disassembly maintenance of the box body 100 by the positioning assembly 10.

[0054] In some embodiments, Figure 4 As shown, the second rod segment 22 includes a first bottom wall 221 and a first side wall 222 connected to each other, the first side wall 222 is arranged around the first bottom wall 221, the arc-shaped groove 23 is arranged on the first side wall 222, the first bottom wall 221 and the first side wall 222 jointly define the second groove 223, and the first shaft segment 41 can be inserted into or disengaged from the second groove 223; the rotating shaft 4 also includes a third protrusion 44, the third protrusion 44 is arranged on the outer wall of the first shaft segment 41 and extends along the first direction, and the third protrusion 44 can be inserted into or disengaged from the arc-shaped groove 23.

[0055] In the embodiment of the present application, when the third protrusion 44 is inserted into the bottom of the arc-shaped groove 23, the first shaft section 41 is inserted into the second groove 223. When the third protrusion 44 is rotated out of the arc-shaped groove 23 and the first side wall 222 is away from the first pressing of the moving rod 2, the first shaft section 41 is also rotated out of the second groove 223. The second groove 223 can be a circular groove, and the inner diameter of the second groove 223 can be greater than or equal to the outer diameter of the second shaft section 42, so that when the third protrusion 44 is inserted into the arc-shaped groove 23, the first shaft section 41 is inserted into the second groove 223. Under the condition of ensuring the pressing force of the rotating shaft 4 on the moving rod 2 and ensuring the positioning effect of the positioning assembly 10, compared with the plate-shaped structure on one side of the rotating shaft 4, the arrangement of the third protrusion 44 and the columnar first shaft section 41 can improve the structural rigidity of the rotating shaft 4, improve the reliability of the rotating shaft 4, and thus improve the reliability of the positioning assembly 10.

[0056] In some embodiments, Figure 4 As shown, the second end 112 of the sleeve 1 is provided with a second through hole 13, and the second through hole 13 is connected to the accommodating cavity 11; Figure 4 and Fig.12As shown, the positioning assembly 10 also includes a sleeve 6, which is connected to the sleeve 1 and is arranged between the second shaft segment 42 and the second through hole 13. Along the first direction, the boundary of the orthographic projection of the second protrusion 43 and the accommodating cavity 11 is located within the orthographic projection of the sleeve 6; a fourth protrusion 61 is also provided on the side of the sleeve 6 away from the moving rod 2, and along the first direction, the boundary of the orthographic projection of the second through hole 13 is located within the orthographic projection boundary of the fourth protrusion 61.

[0057] In the present application embodiment, Figure 4 As shown, the second protrusion 43 is used to limit the depth of the rotating shaft 4 inserted into the sleeve 6, reducing the probability of the positioning assembly 10 failing to position due to the rotating shaft 4 being screwed into the sleeve 6 too deeply, the pressure of the rotating shaft 4 on the moving rod 2 being reduced, and the length of the moving rod 2 extending out of the sleeve 1 after being pressed being reduced. In addition, along the first direction, the boundary of the orthographic projection of the second protrusion 43 and the accommodating cavity 11 is located within the orthographic projection of the sleeve 6, that is, the outer diameter of the second protrusion 43 is smaller than the inner diameter of the sleeve 6, the sleeve 6 is connected to the sleeve 1, and the sleeve 6 can limit the rotating shaft 4 through the second protrusion 43, reducing the probability of the rotating shaft 4 slipping out of the accommodating cavity 11 under the pressure provided by the moving rod 2 during the rotation process, and ensuring the stability of the abutment between the rotating shaft 4 and the connection.

[0058] In the present application embodiment, Figure 4 As shown, along the first direction, the boundary of the orthographic projection of the second through hole 13 is located within the boundary of the orthographic projection of the fourth protrusion 61, that is, the inner diameter of the second through hole 13 is smaller than the outer diameter of the fourth protrusion 61, and the fourth protrusion 61 is used to limit the depth of the sleeve 6 extending into the second through hole 13, thereby reducing the excessive pressure exerted by the sleeve 6 on the rotating shaft 4 due to the sleeve 6 fully extending into the second through hole 13, and reducing the space in the accommodating chamber 11, thereby hindering the probability of the rotation of the rotating shaft 4 and the linear movement of the moving rod 2, and ensuring the positioning effect of the positioning assembly 10. Optionally, along the first direction, the boundary of the orthographic projection of the accommodating chamber 11 is located within the orthographic projection of the sleeve 6, that is, the inner diameter of the accommodating chamber 11 is larger than the inner diameter of the sleeve 6 and smaller than the outer diameter of the sleeve 6, thereby limiting the sleeve 6 through the accommodating chamber 11 to prevent the sleeve 6 from fully extending into the second through hole 13, and ensuring the positioning effect of the positioning assembly 10.

[0059] Optionally, the sleeve 6 is disposed in the second through hole 13, and the sleeve 6 and the sleeve 1 can be interference fit to achieve the clamping limit of the rotating part. The sleeve 6 and the sleeve 1 can also be connected by clamping, threaded connection and other connection methods. The connection method of the sleeve 6 and the sleeve 1 can be set according to actual needs, and this application does not limit this. The material of the sleeve 6 includes but is not limited to metal, plastic, and rubber. When the material of the sleeve 6 is plastic or rubber, the sleeve 6 can be an elastic sleeve 6. At this time, the connection between the sleeve 6 and the sleeve 1 can be achieved by a small pressure, which is convenient for the assembly and preparation of the positioning component 10.

[0060] In some embodiments, Figure 6 and Figure 7 As shown, a limiting groove 24 is provided on one side of the moving rod 2 close to the second end 112. Specifically, a limiting groove 24 is provided on one side of the second rod section 22, and the limiting groove 24 is spaced apart from the arc-shaped groove 23. The limiting groove 24 is used to clamp and limit the third protrusion 44 rotated to the vertex of the arc-shaped groove 23, thereby reducing the probability that the positioning assembly 10 is impacted in the positioning state, causing shaking or vibration, resulting in the third protrusion 44 being re-clamped into the arc-shaped groove 23, thereby reducing the probability that the moving rod 2 re-extends into the accommodating cavity 11 of the sleeve 1, resulting in positioning failure, improving the stability of the positioning assembly 10 in positioning and fixing the box 100, and improving the working stability of the positioning assembly 10.

[0061] In the present application embodiment, Figure 7 As shown, the two side walls of the limit groove 24 that are relatively arranged can be inclined, and the limit groove 24 is an inverted trapezoid as a whole, so that the third protrusion 44 on the rotating shaft 4 can be inserted into or disengaged from the limit groove 24 more smoothly, buffering the impact force received when the third protrusion 44 is inserted into the limit groove 24, improving the stability and reliability of the rotating shaft 4 to rotate to drive the moving rod 2 to move, and reducing the resistance received when the third protrusion 44 is disengaged from the limit groove 24, so that the third protrusion 44 can be easily and quickly disengaged from the limit groove 24, thereby increasing the resistance received by the rotating shaft 4 during the rotation process, and increasing the rotation rate of the rotating shaft 4, so that the moving rod 2 can be more conveniently extended or retracted into the accommodating cavity 11, thereby improving the positioning efficiency of the positioning assembly 10 and improving the installation and maintenance efficiency of the box 100.

[0062] In some embodiments, Figure 1 , Figure 4 and Fig.11 As shown, the positioning assembly 10 also includes a handle 7, which is connected to the rotating shaft 4, specifically, to the second shaft segment 42. The outer wall of the handle 7 is provided with a plurality of evenly and spaced third grooves 71, and the third grooves 71 extend along the first direction. The handle 7 is connected to the second shaft segment 42 of the rotating shaft 4, and when the handle 7 rotates, the rotating shaft 4 is driven to rotate synchronously. The handle 7 is arranged as a whole outside the accommodating chamber 11. The arrangement of the handle 7 can facilitate the maintenance personnel to rotate the rotating shaft 4, thereby simply and conveniently driving the moving rod 2 to extend out of the sleeve 1, realizing the positioning and fixing of the adjacent boxes 100, and improving the installation and maintenance efficiency of the boxes 100. The plurality of evenly and spaced third grooves 71 can increase the friction force on the surface of the handle 7, which can facilitate the maintenance personnel to rotate the handle 7, and can further improve the rotation rate of the rotating shaft 4, improve the positioning efficiency of the positioning assembly 10, and improve the installation and maintenance efficiency of the boxes 100.

[0063] Optionally, a protruding structure may be provided on the side of the handle 7 close to the rotating shaft 4, a thread may be provided on the outer wall of the protruding structure, a recessed structure may be provided on the side of the rotating shaft 4 close to the handle 7, and a thread may be provided on the inner wall of the recessed structure; or, a recessed structure may be provided on the side of the handle 7 close to the rotating shaft 4, a thread may be provided on the inner wall of the recessed structure, a protruding structure may be provided on the side of the rotating shaft 4 close to the handle 7, and a thread may be provided on the outer wall of the protruding structure, and the handle 7 and the rotating shaft 4 may be fixedly connected by threaded connection of the protruding structure and the recessed structure.

[0064] In some embodiments, Figure 1 and Figure 5 As shown, the outer wall of the sleeve 1 is provided with a hanging ear structure 8, the hanging ear structure 8 is located at the second end 112, the hanging ear structure 8 includes a first hanging ear 81 and a second hanging ear 82 arranged opposite to each other, and the first hanging ear 81 and the second hanging ear 82 are both provided with a third through hole 83. The box 100 is provided with a mounting tube 40, and the sleeve 1 is placed in the mounting cavity of the mounting tube 40. The connection between the hanging ear structure 8 and the mounting tube 40 is realized to realize the connection between the positioning assembly 10 and the box 100, so as to facilitate the positioning and fixing of the box 100 installed with the positioning assembly 10 and other adjacent boxes 100. The first hanging ear 81 and the second hanging ear 82 can be symmetrically arranged relative to the axis of the sleeve 1, so that the positioning assembly 10 is subjected to balanced force during the positioning process, thereby improving the working stability and reliability of the positioning assembly 10 and improving the positioning effect. The third through hole 83 can be a threaded hole, and the mounting tube 40 can be provided with two symmetrically arranged threaded holes, which can be passed through threaded fasteners such as screws in sequence through the third through hole 83 and the threaded holes on the mounting tube 40 to achieve a tight connection between the sleeve 1 and the mounting tube 40, which is convenient and has high connection stability.

[0065] Optionally, the sleeve 1 can be a square sleeve 1, and correspondingly, the mounting cylinder 40 can also be a square mounting cylinder 40, or the mounting cavity in the mounting cylinder 40 is square. The shapes of the sleeve 1 and the mounting cylinder 40 can be set according to actual needs, and this application does not limit this.

[0066] The second aspect of the present application provides an LED display device, such as Fig.13 and Fig.14 As shown, the LED display device includes the positioning assembly 10 in any of the above embodiments. The LED display device also includes a plurality of boxes 100 and a plurality of display screens, each box 100 is correspondingly connected to each display screen, the box 100 includes a second bottom wall 101 and a second side wall 102 connected to each other, the second side wall 102 is arranged around the second bottom wall 101 and is perpendicular to the second bottom wall 101, the second bottom wall 101 is used to fix the display screen, and the positioning assembly 10 is vertically arranged on the second side wall 102.

[0067] In the present application embodiment, Figure 6As shown, when positioning and fixing adjacent boxes 100 by means of the positioning assembly 10, the maintenance personnel can first connect the positioning assembly 10 to the second side wall 102 of one of the boxes 100, and then rotate the rotating shaft 4 to disengage the rotating shaft 4 from the arc groove 23. During the process of the rotating shaft 4 rotating and disengaging from the arc groove 23, the rotating shaft 4 will squeeze the arc groove 23 and thus apply pressure to the moving rod 2. Driven by the pressure, the moving rod 2 can slide along the first direction and gradually extend out of the sleeve 1, thereby achieving the positioning and fixing of the adjacent boxes 100. During this process, the elastic member 3 is in a compressed state. Figure 8 and Fig. 9 As shown, when a box 100 needs to be disassembled, the rotating shaft 4 can be rotated again to make the rotating shaft 4 re-engage the bottom of the arc groove 23. At this time, the rotating shaft 4 does not apply pressure to the moving rod 2 or applies less pressure, and the elastic member 3 is gradually restored to the initial extended state due to the reduced force. The moving rod 2 retracts into the sleeve 1 under the elastic force provided by the elastic member 3, thereby realizing the disassembly of the adjacent box 100. The positioning assembly 10 has a simple structure, is easy to operate, and is convenient to disassemble and assemble. The telescopic state of the moving rod 2 can be changed by rotating the rotating shaft 4, and the splicing and disassembly of the box 100 can be realized simply and quickly, thereby improving the installation and maintenance efficiency of the box 100.

[0068] In some embodiments, Fig.13 and Fig.14 As shown, a plurality of spaced-apart mounting tubes 40 are provided on one side of a second side wall 102 away from each other of adjacent boxes 100, a mounting cavity is provided in the mounting tube 40, a sleeve 1 is placed in the mounting cavity, and a hanging ear structure 8 is connected to a side of the mounting tube 40 away from the side wall, thereby realizing the connection between the positioning assembly 10 and the box 100. At this time, the driving rotating shaft 4 is rotated to rotate the third protrusion 44 into the limiting groove 24, so that the moving rod 2 at least partially extends out of the accommodating cavity 11 and passes through the mounting hole on the second side wall 102 of the adjacent box 100, thereby simply and conveniently realizing the positioning and fixation of the adjacent boxes 100, and improving the installation and maintenance efficiency of the box 100.

[0069] In some embodiments, Fig.15As shown, the first side wall 222 of each box 100 includes a plurality of first mounting holes 201 arranged at intervals, and the axes of the first mounting holes 201 on adjacent boxes 100 coincide with each other. After the moving rod 2 extends out of the sleeve 1, it passes through two adjacent first mounting holes 201 at the same time, avoiding displacement between adjacent boxes 100, thereby simply and conveniently realizing the positioning and fixing of adjacent boxes 100. Optionally, the first mounting holes 201 of the two adjacent boxes 100 through which the moving rod 2 passes can both be through holes, in which case the positioning assembly 10 can be connected to any box 100 to realize the positioning and fixing of the two boxes 100; the two first mounting holes 201 can also be one through hole and one countersunk hole, and the moving rod 2 in the positioning assembly 10 can pass through the through hole and the countersunk hole in sequence to realize the positioning and fixing of the two boxes 100.

[0070] In some embodiments, Fig.16 As shown, the box 100 includes a first box 20 and a second box 30 arranged adjacently, and the second side wall 102 of the first box 20 includes at least one first mounting hole 201. After the ear structure 8 is connected to the mounting tube 40, the sleeve 1 can be inserted into the first mounting hole 201, and the side surface of one end 111 of the sleeve 1 is flush with the second side wall 102 with the first mounting hole 201. The side wall of the second box 100 includes at least one second mounting hole 301, and the axis of the first mounting hole 201 coincides with the axis of the second mounting hole 301. At least part of the moving rod 2 extending out of the sleeve 1 is inserted into the second mounting hole 301, so as to realize the positioning and fixing of the adjacent boxes 100 in a simple and convenient manner. Optionally, the first mounting hole 201 is a through hole to facilitate the insertion of the sleeve 1, and the second mounting hole 301 can be a through hole or a countersunk hole to facilitate the accommodation of the moving rod 2 extending out of the sleeve 1, so as to realize the positioning and fixing of the two boxes 100.

[0071] Optionally, the connection method between the positioning assembly 10 and the box body 100 can be set according to actual needs, and this application does not limit this.
