When in use, the mounting frame is fixed to the wall. When disassembling the unit board, the mounting frame needs to be removed from the wall and then the unit board needs to be removed. The connection method is not flexible enough and is quite troublesome to use. Summary of the Invention

[0004] To address the aforementioned problems, this utility model proposes a unit plate connection structure to more accurately resolve the problems described above.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model proposes a unit board connection structure, including a housing, an installation plate fixedly connected to the inner wall of the housing, a circuit board fixedly installed on one side of the installation plate, a placement frame fixedly connected to one side of the housing, and installation blocks fixedly connected to both sides of the housing. The installation blocks are provided with slots and penetrate through the placement frame. A unit board is placed inside the placement frame. Two insertion rods are provided on one side of the unit board, and a fixing component is provided inside the installation block.

[0007] Furthermore, the fixing component includes a sliding rod that is slidably connected to the mounting block. The mounting block has a placement groove in the area above the slot. The sliding rod is located in the placement groove. The lower end of the sliding rod passes through the side wall of the placement groove and extends into the insertion hole. A fixing plate is fixedly connected to the outside of the sliding rod. A first spring is fixedly connected between the fixing plate and the upper bottom surface of the placement groove. The insertion rod has an insertion hole.

[0008] Furthermore, the cross-sections of the insertion hole and the sliding rod on the insertion rod are both circular, the radius of the insertion hole is larger than the radius of the sliding rod, the lower end of the sliding rod is circular, and the side wall of the insertion hole is provided with a guide slope.

[0009] Furthermore, the two sliding rods extend upward through the mounting block, and the upper ends of the two sliding rods are fixedly connected to vertical plates, with a support plate fixedly connected between the two vertical plates.

[0010] Furthermore, a pull ring is fixedly connected to the upper surface of the support plate.

[0011] Furthermore, the bottom surface of the slot on the mounting block is provided with a sliding groove, a slider is slidably connected in the sliding groove, a push plate is fixedly connected to the upper surface of the slider, the cross-sectional size and shape of the push plate are the same as those of the slot, and a second spring is fixedly connected between the slider and the sliding groove.

[0012] Furthermore, the mounting block has a square groove inside, which is connected to the placement groove and the slot.

[0014] The beneficial effects of this utility model are:

[0015] This utility model proposes a unit board connection structure. By setting up insert rods and mounting blocks, during installation, two insert rods are inserted into slots on the mounting blocks. The operator lifts the pull ring, causing the sliding rod to move upward to avoid the insert rods. Then, the unit board is pushed, allowing the insert rods to continue into the slots. The pull ring is released, and when the insert rods are aligned with the insertion holes, the first spring pushes the sliding rod into the insertion holes to fix the insert rods, thereby fixing the unit board in the placement frame. During disassembly, simply pull the sliding rod away from the insertion holes and then remove the unit board from the placement frame. This makes the disassembly and installation of the unit board quite convenient.

[0016] A unit panel connection structure is provided. When a sliding rod is inserted into the insertion hole on the insert rod, the sliding rod drives the pressure plate to descend together. The pressure plate pushes the vertical rod down, so that the conical rubber block at the lower end of the vertical rod is inserted into the conical groove on the insert rod. The conical rubber block is squeezed into the rubber sleeve, making the insert rod and the vertical rod more tightly connected. This prevents the unit panel from shaking in the placement frame after the insert rod on the unit panel is inserted into the slot. Attached Figure Description

[0022] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0023] Please refer to Figures 1-4 This utility model proposes a unit board connection structure, characterized by comprising a housing 1, an mounting plate 2 fixedly connected to the inner wall of the housing 1, a circuit board 3 fixedly mounted on one side of the mounting plate 2, a placement frame 4 fixedly connected to one side of the housing 1, and mounting blocks 5 fixedly connected to both sides of the housing 1. The mounting blocks 5 have slots and penetrate the placement frame 4. A unit board 6 is placed inside the placement frame 4. Two insertion rods 7 are provided on one side of the unit board 6. A fixing component 8 is provided inside the mounting blocks 5. LED unit boards 6 with LED beads are mostly mounted on walls. The housing 1 is fixed to the wall with bolts, while the circuit board 3 of the control unit board 6 is fixed to the housing 1 with screws. The unit board 6 is placed on the mounting plate 2 and in the placement frame 4 on one side of the housing 1. It is connected to the circuit board 3 by wires. Two plugs 7 on one side of the unit board 6 are inserted into the mounting block 5 and fixed by the internal fixing component 8. When the unit board 6 needs to be repaired or replaced, the fixing component 8 can be released to remove the plugs 7 and the unit board 6 can be taken out from the placement slot without disassembling the housing 1 and the circuit board 3. After the repair is completed, the plugs 7 on the unit board 6 can be inserted back into the slots on the mounting block 5. Compared with the method of fixing the unit board 6 to the housing with bolts, this method is more convenient for the disassembly and installation of the unit board 6.

[0024] like Figure 2 and Figure 3 as well as Figure 4As shown, the fixing assembly 8 includes a sliding rod 81, which is slidably connected to the mounting block 5. A placement groove is provided in the area above the slot within the mounting block 5. The sliding rod 81 is located within the placement groove, with its lower end penetrating downwards through the side wall of the placement groove. The lower end of the sliding rod 81 extends into the insertion hole. A fixing plate 82 is fixedly connected to the outer side of the sliding rod 81. A first spring 83 is fixedly connected between the fixing plate 82 and the upper bottom surface of the placement groove. An insertion hole is provided on the insertion rod 7. The cross-sections of the insertion hole and the sliding rod 81 are both circular, with the radius of the insertion hole being larger than the radius of the sliding rod 81. The lower end of the sliding rod 81 is circular. A guide slope is provided on the side wall of the insertion hole. Two sliding rods 81 penetrate upwards through the mounting block 5. Vertical plates 9 are fixedly connected to the upper ends of both sliding rods 81. A support plate 10 is fixedly connected between the two vertical plates 9. The upper part of the support plate 10... The surface is fixedly connected to the pull ring 11. During installation, the two insert rods 7 are inserted into the slots on the mounting block 5, so that the weight of the unit board 6 presses on the mounting block 5. Then, the operator lifts the pull ring 11, causing the sliding rod 81 to move upward to avoid the insert rods 7. Then, the unit board 6 is pushed so that the insert rods 7 continue to enter the slots. The pull ring 11 is released. When the insert rods 7 are aligned with the insertion holes, the first spring 83 pushes the sliding rod 81 into the insertion holes to fix the insert rods 7, thereby fixing the unit board 6 in the placement frame 4. When disassembling, simply pull the sliding rod 81 away from the insertion holes and then take the unit board 6 out of the placement frame 4. The operation is simple. By setting the vertical plate 9, the horizontal plate 10 and the pull ring 11, the two sliding rods 81 can be pulled with one hand, which is convenient for operation. At the same time, by setting the guide slope, the sliding rods 81 are more easily inserted into the insertion holes.

[0025] like Figure 4 As shown, the bottom surface of the slot on the mounting block 5 is provided with a sliding groove, and the slider 12 is slidably connected in the sliding groove. The upper surface of the slider 12 is fixedly connected to the push plate 13. The cross-sectional size and shape of the push plate 13 are the same as those of the slot. The second spring 14 is fixedly connected between the slider 12 and the sliding groove. When the insertion rod 7 is inserted into the slot, it pushes the push plate 13 to move, and the second spring 14 is compressed and stored. When disassembling, after the sliding rod 81 leaves the insertion hole, the second spring 14 stores its force, and the push plate 13 pushes the insertion rod 7 out of the slot, thereby causing the unit board 6 to leave the placement frame 4. This avoids the gap between the placement frame 4 and the unit board 6 being too small, which would prevent the staff from taking out the unit board 6.

[0026] like Figure 4As shown, the mounting block 5 has a square groove inside, which communicates with the placement groove and the slot. A horizontal plate 10 is fixedly connected to one side of the square groove. A vertical rod 15 is slidably connected to the horizontal plate 10. A limiting block 16 is fixedly connected to the upper end of the vertical rod 15. A third spring 17 is fixedly connected between the limiting block 16 and the horizontal plate 10. A conical rubber block 18 is fixedly connected to the lower end of the vertical rod 15. The insertion rod 7 has a conical groove, and a rubber sleeve 19 is fixedly connected to the inner wall of the conical groove. The rubber sleeve 19 cooperates with the conical rubber block 18. A fixing ring 20 is fixedly connected to the outer side of the vertical rod 15. A fixing plate 82 is fixedly connected to one side of the vertical rod 15. The vertical rod 15 passes through the pressure plate 21 and is slidably connected to the pressure plate 21. The pressure plate 21 is located above the fixing ring 20. When the second spring 14 pushes the sliding rod 81 to insert into the insertion hole on the insertion rod 7, the sliding rod 81 drives the pressure plate 21 to descend together. The pressure plate 21 pushes the vertical rod 15 to descend, so that the conical rubber block 18 at the lower end of the vertical rod 15 is inserted into the conical groove on the insertion rod 7. The conical rubber block 18 is squeezed into the rubber sleeve 19, making the insertion rod 7 and the vertical rod 15 more tightly connected, thereby preventing the unit board 6 from shaking in the placement frame 4 after the insertion rod 7 on the unit board 6 is inserted into the slot.

[0027] Working principle: The housing 1 is fixed to the wall with bolts. Two insert rods 7 on one side of the unit panel 6 are inserted into the mounting block 5, so that the weight of the unit panel 6 presses on the mounting block 5. Then, the operator lifts the pull ring 11, causing the sliding rod 81 to move upward to avoid the insert rods 7. Then, the unit panel 6 is pushed, so that the insert rods 7 continue to enter the slot. The pull ring 11 is released. When the insert rods 7 are aligned with the insertion hole, the first spring 83 pushes the sliding rod 81 to insert into the insertion hole and fix the insert rods 7. The sliding rod 81 drives the pressure plate 21 together. As the vertical rod 15 descends, the pressure plate 21 pushes it down, causing the conical rubber block 18 at the lower end of the vertical rod 15 to insert into the conical groove on the insertion rod 7. The conical rubber block 18 is squeezed into the rubber sleeve 19, making the insertion rod 7 and the vertical rod 15 more tightly connected. When the insertion rod 7 is inserted into the slot, it pushes the push plate 13 to move, and the second spring 14 is compressed and stored. When disassembling, after the sliding rod 81 leaves the insertion hole, the second spring 14 stores its power, and the push plate 13 pushes the insertion rod 7 out of the slot, thereby causing the unit plate 6 to leave the placement frame 4.

[0028] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
