[0007] Furthermore, the driving component includes a magnetic suction component disposed within the adjustment groove. The magnetic suction component is located between the first contact surface and the first sliding surface. The magnetic suction component can provide a driving force to the sliding component, thereby moving the sliding component to the adjustment position.

[0008] Furthermore, the wall of the adjusting groove also has a third sliding surface, and the first end of the sliding member is also provided with a fourth sliding surface connected to the second sliding surface. The second sliding surface is located on the side of the fourth sliding surface away from the first contact surface. The magnetic suction member is in contact with the third sliding surface. When the sliding member moves to the adjusting position, the magnetic suction member is in contact with the fourth sliding surface.

[0009] Furthermore, the first end of the slider is also provided with a first clearance surface, which is connected to the side of the fourth sliding surface away from the second sliding surface. When the slider moves to the adjustment position, there is a gap between the first clearance surface and the magnetic attractor.

[0010] Furthermore, the wall of the adjusting groove also has a second clearance surface to avoid the magnetic suction component. The second clearance surface is connected to the first sliding surface and the third sliding surface respectively. When the sliding component moves to the adjusting position, there is a gap between the second sliding surface and the second clearance surface.

[0011] Furthermore, the sliding member includes a sliding column and a slider connected to the first end of the sliding column. One of the first adjusting seat and the second adjusting seat is provided with a receiving groove. The sliding column and the slider are slidably disposed in the receiving groove.

[0012] Furthermore, the slider is provided with a first protrusion and a second protrusion. The first protrusion is located on the side of the second protrusion away from the first contact surface. The second sliding surface extends to the first protrusion. One of the first adjusting seat and the second adjusting seat is also provided with a first clearance groove and a second clearance groove that communicate with the receiving groove. The first protrusion extends into the first clearance groove, and the second protrusion extends into the second clearance groove.

[0013] Furthermore, both the first sliding surface and the second sliding surface are inclined surfaces. When the slider is in the adjustment position, the first sliding surface and the second sliding surface are in contact. When the slider moves from the adjustment position to the maintenance position, the first sliding surface slides relative to the second sliding surface and separates. And / or, the driving component also includes a driving spring, which is sleeved on the slider. The first end of the driving spring is in contact with one of the first adjustment seat and the second adjustment seat, and the second end of the driving spring abuts against the slider.

[0016] The adjustment mechanism of this utility model includes a first adjustment seat, a second adjustment seat, and an adjustment component. The first adjustment seat is connected to the first housing via a first connecting part, and the second adjustment seat is connected to the second housing via a second connecting part. During the assembly of the LED display device, the driving force provided by the driving component causes the sliding member to move relative to the first and second adjustment seats. The first end of the sliding member slides into the adjustment groove, and the sliding member is in the adjustment position. The first and second contact surfaces are coplanar, thereby making the rear sides of the first and second housings coplanar and eliminating misalignment between the first and second housings. During maintenance, when removing the first or second housing from the frame, the first sliding surface can slide relative to the second sliding surface. The groove wall of the adjustment groove applies force to the sliding member and overcomes the driving force provided by the driving component, causing the sliding member to disengage from the adjustment groove and move to the maintenance position. At this time, the sliding member separates from the other of the first and second adjustment seats, and the first or second housing can be removed from the frame. Furthermore, since the wall of the adjustment groove can apply force to the sliding parts, the housing can be easily installed and removed from the frame regardless of whether front maintenance or rear maintenance is used, realizing the misalignment adjustment between two adjacent housings in the front maintenance state.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0036] like Figures 1 to 11As shown, this utility model embodiment provides an adjustment mechanism, which includes a first adjustment seat 10, a second adjustment seat 20, and an adjustment component 30. The first adjustment seat 10 has a first contact surface that fits against a first housing and a first connecting portion that connects to the first housing. The second adjustment seat 20 has a second contact surface that fits against a second housing and a second connecting portion that connects to the second housing. The adjustment component 30 includes a slider 31 and a drive component 32. The slider 31 is slidably disposed on one of the first adjustment seat 10 and the second adjustment seat 20. Another part of the seat 20 is provided with an adjustment groove 21. The driving member 32 can provide driving force to the sliding member 31 so that the first end of the sliding member 31 slides into the adjustment groove 21 and is located in the adjustment position. The first contact surface and the second contact surface are coplanar. The groove wall of the adjustment groove 21 has a first sliding surface 211, and the first end of the sliding member 31 has a second sliding surface 311. The adjustment groove 21 and the sliding member 31 slide relative to each other through the first sliding surface 211 and the second sliding surface 311 to overcome the driving force, so that the sliding member 31 is dislodged from the adjustment groove 21 and moved from the adjustment position to the maintenance position.

[0037] The adjustment mechanism of this utility model includes a first adjustment seat 10, a second adjustment seat 20, and an adjustment component 30. The first adjustment seat 10 is connected to the first housing by a first connecting part, and the second adjustment seat 20 is connected to the second housing by a second connecting part. When assembling the LED display device, the driving force provided by the driving component 32 causes the sliding component 31 to move relative to the first adjustment seat 10 and the second adjustment seat 20. The first end of the sliding component 31 slides into the adjustment groove 21, and the sliding component 31 is in the adjustment position. The first contact surface and the second contact surface are coplanar, thereby making the rear side of the first housing and the rear side of the second housing coplanar, eliminating the misalignment between the first housing and the second housing. During maintenance, as the first or second housing is removed from the frame, the first sliding surface 211 can slide relative to the second sliding surface 311. The wall of the adjusting groove 21 applies force to the sliding member 31 and overcomes the driving force provided by the driving member 32, causing the sliding member 31 to disengage from the adjusting groove 21 and move to the maintenance position. At this time, the sliding member 31 separates from the other of the first adjusting seat 10 and the second adjusting seat 20, and the first or second housing can be removed from the frame. Furthermore, since the wall of the adjusting groove 21 can apply force to the sliding member 31, the housing can be easily installed and removed from the frame regardless of whether front or rear maintenance is used, realizing the misalignment adjustment between adjacent housings in the front maintenance state.

[0038] It should be noted that the first and second housings are two adjacent housings 50, which can be arranged either vertically or horizontally. Furthermore, the orientation of the first sliding surface 211 and the second sliding surface 311 is related to the orientation of the two housings 50.

[0039] The first sliding surface 211 and the second sliding surface 311 can be either inclined or curved. When using a curved surface, a well-fitting planar structure should be provided to match the curved surface to ensure the stability of the assembled LED display device.

[0040] In this embodiment, both the first adjusting seat 10 and the second adjusting seat 20 are provided with positioning protrusions on the side facing the housing 50, and are positioned on the housing 50 by means of the positioning protrusions.

[0041] The adjustment mechanism provided in this embodiment has a simple structure that can be machined or molded.

[0042] like Figure 2 and Figure 3 As shown, the driving component 32 includes a magnetic suction component 321, which is disposed within the adjustment groove 21. The magnetic suction component 321 provides a driving force to the sliding component 31, causing the sliding component 31 to move to the adjustment position. The magnetic suction component 321 provides magnetic attraction, which strengthens the locking force and ensures accurate locking. Furthermore, placing the magnetic suction component 321 between the first contact surface and the first sliding surface 211 facilitates its arrangement and saves space.

[0043] Among them, the magnetic component 321 takes the form of a magnetic plate and is made of a magnetic material such as iron, cobalt, or nickel.

[0044] In other embodiments, the magnetic suction element 321 may be disposed on the first sliding surface 211.

[0045] like Figure 4 and Figure 6 As shown, the wall of the adjustment groove 21 also has a third sliding surface 213, and the first end of the slider 31 is also provided with a fourth sliding surface 312 connected to the second sliding surface 311. The second sliding surface 311 is located on the side of the fourth sliding surface 312 away from the first contact surface. The magnetic suction member 321 is in contact with the third sliding surface 213. When the slider 31 moves to the adjustment position, the magnetic suction member 321 is in contact with the fourth sliding surface 312. With the above structure, the second sliding surface 311 and the fourth sliding surface 312 are arranged opposite each other, and the first sliding surface 211 and the third sliding surface 213 are arranged opposite each other. When disassembling and assembling the housing 50, either the first sliding surface 211 or the third sliding surface 213 can slide relative to the corresponding sliding surface, thereby making it easier for the slider 31 to enter or leave the adjustment groove 21.

[0046] In this embodiment, both the first sliding surface 211 and the third sliding surface 213 are disposed on the bottom wall of the adjusting groove 21.

[0047] The magnetic suction component 321 is positioned at the fourth sliding surface 312, making full use of the bottom wall structure of the adjustment groove 21, which is beneficial to the stable fixation of the magnetic suction component 321 and gives it a larger area.

[0048] like Figure 2 and Figure 4 As shown, the first end of the slider 31 is also provided with a first clearance surface 313. The first clearance surface 313 is connected to the side of the fourth sliding surface 312 away from the second sliding surface 311. When the slider 31 moves to the adjustment position, there is a gap between the first clearance surface 313 and the magnetic attractor 321. With the above structure, the magnetic attraction area between the magnetic attractor 321 and the slider 31 can be reduced, making them easier to separate and making it easier for the slider 31 to be removed from the adjustment groove 21 for maintenance.

[0049] like Figure 2 and Figure 6 As shown, the wall of the adjustment groove 21 also has a second clearance surface 214 to avoid the magnetic suction member 321. The second clearance surface 214 is connected to the first sliding surface 211 and the third sliding surface 213 respectively. When the sliding member 31 moves to the adjustment position, there is a gap between the second sliding surface 311 and the second clearance surface 214. With the above structure, by using the second clearance surface 214 to avoid the magnetic suction member 321, it is possible to install the magnetic suction member 321 into the adjustment groove 21 even with a large volume.

[0050] like Figure 3 and Figure 4 As shown, the slider 31 includes a sliding column 314 and a slider 315 connected to the first end of the sliding column 314. A receiving groove 11 is provided on one of the first adjusting seat 10 and the second adjusting seat 20. Both the sliding column 314 and the slider 315 are slidably disposed within the receiving groove 11. A second sliding surface 311 and a fourth sliding surface 312 are both disposed on the slider 315. The slider 31 with the above structure has the advantages of simple structure and ease of processing.

[0051] like Figure 4 and Figure 5As shown, the slider 315 is provided with a first protrusion 316 and a second protrusion 317. The first protrusion 316 is located on the side of the second protrusion 317 away from the first contact surface. The second sliding surface 311 extends to the first protrusion 316, and the fourth sliding surface 312 extends to the second protrusion 317. One of the first adjusting seat 10 and the second adjusting seat 20 is also provided with a first clearance groove 12 and a second clearance groove 13 communicating with the receiving groove 11. The first protrusion 316 extends into the first clearance groove 12, and the second protrusion 317 extends into the second clearance groove 13. With the above-described structure, the slider 31, through the arrangement of the slider 315, the first protrusion 316, and the second protrusion 317, can increase the area of ​​the second sliding surface 311 and the fourth sliding surface 312, making the contact area between the slider 31 and the adjusting groove 21 larger, and making the slider 31 more stable when adjusting the position.

[0052] In this embodiment, for ease of maintenance, the first clearance groove 12 penetrates the side wall of the first adjustment seat 10, and the first protrusion 316 extends out of the first clearance groove 12. The operator can move the slider 31 by operating the first protrusion 316.

[0053] The lower end of the sliding column 314 extends through the first adjusting seat 10 and is secured to the outer wall of the first adjusting seat 10 by a snap ring to limit the sliding column 314 and prevent the sliding member 31 from coming off the first adjusting seat 10.

[0054] like Figure 4 As shown, both the first sliding surface 211 and the second sliding surface 311 are inclined surfaces. When the slider 31 is in the adjustment position, the first sliding surface 211 and the second sliding surface 311 are in contact. When the slider 31 moves from the adjustment position to the maintenance position, the first sliding surface 211 slides relative to the second sliding surface 311 and separates. The inclined surface structure facilitates the relative sliding of the first sliding surface 211 and the second sliding surface 311, thus benefiting the operator.

[0055] like Figure 2 As shown, the driving member 32 also includes a driving spring 322, which is sleeved on the sliding member 31. The first end of the driving spring 322 is in contact with one of the first adjusting seat 10 and the second adjusting seat 20, and the second end of the driving spring 322 abuts against the sliding member 31. The driving spring 322 can provide driving force to the sliding member 31, so that the sliding member 31 is held in the adjusted position.

[0056] Since the slider 31 is held in the adjustment position by the driving force of the drive spring 322, when the box 50 is placed on the frame 40, the first sliding surface 211 provided on the bottom wall of the adjustment groove 21 can abut against the slider 31, so that the slider 31 overcomes the driving force of the drive spring 322 and moves away from the adjustment groove 21, so as to ensure that the box 50 can be assembled smoothly.

[0057] like Figure 3 and Figure 5 As shown, the adjustment mechanism also includes a first connecting member and a second connecting member. The first connecting part includes a first clearance hole 14 to avoid the first connecting member, and the second connecting part includes a second clearance hole 22 to avoid the second connecting member. Using the aforementioned clearance holes has the advantages of simple structure and ease of processing.

[0058] like Figures 7 to 11 As shown, another embodiment of this utility model provides an LED display device, which includes a frame 40, multiple housings 50, and an adjustment mechanism. The multiple housings 50 are arrayed and arranged on the front side of the frame 40. The adjustment mechanism is arranged between two adjacent housings 50, and the adjustment mechanism is the one provided above. When assembling the LED display device, the driving force provided by the driving member 32 is used to move the sliding member 31 relative to the first adjustment seat 10 and the second adjustment seat 20. The first end of the sliding member 31 slides into the adjustment groove 21, and the sliding member 31 is in the adjustment position. The first contact surface and the second contact surface are coplanar, thereby making the rear side of the first housing and the rear side of the second housing coplanar, eliminating the misalignment between the first housing and the second housing. During maintenance, as the first or second housing is removed from the frame, the first sliding surface 211 can slide relative to the second sliding surface 311. The wall of the adjusting groove 21 applies force to the sliding member 31 and overcomes the driving force provided by the driving member 32, causing the sliding member 31 to disengage from the adjusting groove 21 and move to the maintenance position. At this time, the sliding member 31 separates from the other of the first adjusting seat 10 and the second adjusting seat 20, and the first or second housing can be removed from the frame. Furthermore, since the wall of the adjusting groove 21 can apply force to the sliding member 31, the housing can be easily installed and removed from the frame regardless of whether front or rear maintenance is used, realizing the misalignment adjustment between adjacent housings in the front maintenance state.

[0059] In this embodiment, a magnet is provided on the rear side of the housing 50, and the housing 50 is attracted to the frame 40 by the magnet.

[0060] In this configuration, the display surface of the LED display device is the front, and the direction from the cabinet 50 to the frame 40 is the rear.

[0061] Specifically, two adjacent boxes 50 in the horizontal direction are connected by a connecting piece, and two adjacent boxes 50 in the vertical direction are connected by an adjustment mechanism to eliminate misalignment.

[0062] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
