Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0032] Example 1: See Figure 1-10 An LED display unit maintenance positioning and placement device includes a base plate 10. A slotted seat 40 is mounted on the base plate 10 via a sliding structure 30. The slotted seat 40 can slide left and right on the base plate 10 to adjust its position. A horizontally protruding boss 41 is provided on the opposite side of the left and right side walls of the slotted seat 40. A placement platform 42 for placing an LED display unit 60 is formed on the upper side of the boss 41. A support cover 20 is also installed on the base plate 10. The slotted seat 40 is located inside the support cover 20. The front side of the support cover 20 is open. A maintenance window 22 is provided on the top of the upper side of the support cover 20.

[0033] The base plate 10 is used to install the slotted seat 40 via the sliding structure 30 and to install the support cover 20. During maintenance, the LED display unit 60 is placed on the placement platform 42 of the slotted seat 40, and the maintenance personnel's hands can be rested on the support cover 20 to reduce arm fatigue. During maintenance, the slotted seat 40 can be moved left and right to align different areas of the LED display unit 60 with the maintenance window 22, thereby adjusting the maintenance position.

[0034] In this embodiment, the maintenance window 22 is a rectangular window set in the front-to-back direction.

[0035] In this embodiment, when placing the LED display unit 60 onto the placement platform 42, the LED display unit 60 can be inserted into the placement platform 42 from the open side of the support cover 20.

[0036] See Figure 5 The slotted seat 40 has a baffle 43 fixedly installed at the rear end of the boss 41 to limit the LED display unit 60 when it is inserted. When the LED display unit 60 abuts against the baffle 43, the insertion of the LED display unit 60 is stopped.

[0037] In this embodiment, see Figure 5 The sliding structure 30 includes linear guide rails 31 and sliders 32. Two linear guide rails 31 are mounted in parallel on the base plate 10. Two sliders 32 are mounted on each linear guide rail 31. The slotted seat 40 is mounted on the sliders 32 by screws.

[0038] Example 2: Based on Example 1, see Figure 2 , 3 4, 5, A positioning device 50 is also installed at the rear end of the left or right side of the slotted seat 40. The positioning device 50 positions the slotted seat 40 in the left and right directions to prevent the slotted seat 40 from sliding arbitrarily to the left or right.

[0039] Specifically, see Figure 5 The positioning device 50 includes a slide block 51, a slide rod 52, an end plate 53, and a first spring 54. The slide block 51 is fixedly installed on the rear end of the left or right side of the slotted seat 40. The slide block 51 is provided with a sliding hole that runs through it in the front-back direction. The slide rod 52 slides through the sliding hole. The end plate 53 is fixedly installed on the front end of the slide rod 52. The first spring 54 is fitted on the slide rod 52 between the slide block 51 and the end plate 53. A limiting member 56 is installed on the rear end of the slide rod 52. The rear end of the support cover 20 is provided with an elongated hole 24 in the left-right direction. The rear end of the slide rod 52 passes through the elongated hole 24. The limiting member 56 is located outside the support cover 20 and elastically abuts against the support cover 20.

[0040] In one embodiment, the sliding hole on the slide block 51 is a round hole, the slide rod 52 is a cylindrical structure, and the limiting member 56 is a retaining ring or nut fixed on the slide rod 52. With this embodiment, the limiting member 56 is in elastic contact with the support cover 20, and the friction between the limiting member 56 and the support cover 20 prevents the slotted seat 40 from sliding freely left and right.

[0041] When a retaining ring structure is used, the retaining ring can be a flat washer welded to the slide rod 52; when a nut is used, the rear end of the slide rod 52 is provided with external threads, and the nut is screwed onto the slide rod 52.

[0042] In the preferred embodiment, see Figure 5 The sliding hole on the slide block 51 is a polygonal hole, the slide rod 52 is a polygonal column structure, the limiting member 56 is a triangular block welded and fixed to the slide rod 52, and the support cover 20 has a rack 25 fixedly installed on the upper and / or lower side of the elongated hole 24. The limiting member 56 engages with the rack 25 for limiting, such as... Figure 2 As shown. The triangular block engages with the rack 25 for better positioning and stability.

[0043] When the triangular block engages with the rack 25 for positioning, a handle 55 is installed at the rear end of the slide rod 52 to facilitate pulling the slide rod 52 backward, thereby disengaging the triangular block from the rack 25 and allowing the slotted seat 40 to be adjusted approximately. The handle 55 can be a hand-tightening bolt, which is screwed into the threaded hole at the rear end of the slide rod 52 for fixation.

[0044] Example 3: Based on Example 1 or Example 2, see Figure 5 Drawer slides 45 are installed on both the left and right sides of the slotted seat 40, and supports 46 are installed on the outer side of the drawer slides 45. The supports 46 are mounted on the sliding structure 30. Through the above structure, the slotted seat 40 can be pulled outward. After the slotted seat 40 is pulled out, the LED display unit 60 can be placed directly on the slotted seat 40, reducing the friction between the LED display unit 60 and the slotted seat 40.

[0045] In this embodiment, the two supports 46 are respectively mounted on the sliders 32 on both sides of the sliding structure 30 by screws.

[0046] The drawer slide 45 utilizes existing technology, such as drawer slides used on the sides of the drawer. The drawer slide 45 is a three-section drawer slide, allowing the slotted seat 40 to fully extend. Furthermore, after the slotted seat 40 is pushed into the support cover 20, the drawer slide 45's built-in limiting structure can limit the slotted seat 40, preventing it from sliding out on its own. During installation, the drawer slide 45 is connected to the support 46 and the slotted seat 40 using screws.

[0047] Example 4: Based on Embodiment 1, Embodiment 2, or Embodiment 3, in order to facilitate the placement of the LED display unit 60 onto the slotted base 40, a gap of 2-3mm needs to be provided between the two placement platforms 42. However, after setting the gap, the LED display unit 60 will wobble during maintenance. Therefore, see... Figure 5 , 6 In this embodiment, the slotted seat 40 is also equipped with a clamping mechanism 70 on the upper side of the boss 41 on one side. By setting the clamping mechanism 70 on the upper side of the boss 41, the LED display unit 60 can be elastically clamped to prevent the LED display unit 60 from shaking on the placement platform 42.

[0048] Specifically, see Figure 6 The clamping mechanism 70 includes a clamping block 71, a pull rod 72, and a second spring 73. The slotted seat 40 has a blind hole 44 on the upper side of the boss 41 on one side. The clamping block 71 is slidably installed in the blind hole 44 on the side facing the boss 41. The pull rod 72 passes through the blind hole 44 from the side of the slotted seat 40 away from the boss 41 and is connected and fixed to the clamping block 71. The second spring 73 is located in the blind hole 44. One end of the second spring 73 abuts against the slotted seat 40, and the other end abuts against the clamping block 71. When placing the LED display unit 60 onto the placement platform 42, first place one end of the LED display unit 60 onto the side of the placement platform 42 without the clamping mechanism 70, then pull out the lever 72 on the other side of the placement platform 42 to retract the clamping block 71 into the blind hole 44. Then place the other end of the LED display unit 60 onto the side of the placement platform 42 with the clamping mechanism 70, and then release the lever 72. The clamping block 71 extends under the action of the second spring 73 and elastically abuts against the LED display unit 60.

[0049] See Figure 6 The pull rod 72 has a large end and a screw end. The screw end passes through the blind hole 44 from the side of the slotted seat 40 away from the boss 41. The back of the clamping block 71 is provided with a threaded hole. The screw end is screwed and fixed to the threaded hole on the back of the clamping block 71.

[0050] Example 5: Based on Example 1, Example 2, Example 3, or Example 4, see [link to example]. Figure 7 , 8 9. The support cover 20 is formed by bending sheet metal. Since the front side of the support cover 20 is open, the front structural strength of the support cover 20 is low. Therefore, the support cover 20 has a folded edge 23 on the upper side of the open end to improve the structural strength of the front end of the support cover 20.

[0051] In addition, in order to facilitate the installation of the support cover 20 onto the base plate 10, an outwardly bent extension plate 21 is provided on the lower side of the support cover 20. The extension plate 21 is provided with mounting holes and is bolted to the base plate 10 through the mounting holes.

[0052] The working principle or process of this utility model: See Figure 1 , 2 3, 4. When the device is not equipped with drawer slide 45, the LED display unit 60 can be inserted into the placement table 42 from the open side of the support cover 20. During maintenance, the maintenance personnel's hands can be rested on the support cover 20 to reduce arm fatigue. During the maintenance process, the maintenance position can be adjusted by moving the slotted seat 40 left and right to align different areas of the LED display unit 60 with the maintenance window 22.

[0053] See Figure 10 When the device is equipped with drawer slide 45, first pull out the slotted seat 40. After the slotted seat 40 is pulled out, the LED display unit 60 can be placed directly on the slotted seat 40. When placing the LED display unit 60 on the placement platform 42, first place one end of the LED display unit 60 on the side of the placement platform 42 without the clamping mechanism 70. Then pull out the pull rod 72 on the other side of the placement platform 42 to retract the clamping block 71 into the blind hole 44. Then place the other end of the LED display unit 60 on the side of the placement platform 42 with the clamping mechanism 70. Then release the pull rod 72, and the clamping block 71 extends under the action of the second spring 73, elastically abutting against the LED display unit 60. After the slotted seat 40 is pushed into the support cover 20, the limiting structure of the drawer slide 45 can limit the slotted seat 40 and prevent the slotted seat 40 from sliding out on its own.

[0054] When the limiting component 56 uses the triangular block to engage with the rack 25 for limiting, when the maintenance position of the LED display unit 60 needs to be adjusted, the sliding rod 52 is pulled outward by the handle 55 to disengage the triangular block from the rack 25, which means the slot seat 40 is moved left and right. When adjusting the structure, the handle 55 is released, the triangular block engages with the rack 25, and the slot seat 40 is positioned.
