[0038] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0039] This application discloses a lightbox frame connection structure. (Refer to...) Figure 1 , Figure 2 and Figure 4 It includes a first frame 100 and a second frame 200. The second frame 200 has a horizontal limiting member 400 at its end. The first frame 100 has a limiting block 300 corresponding to the horizontal limiting member 400 at its end. The horizontal limiting member 400 and the limiting block 300 are inserted into each other. The bottom of the limiting block 300 is provided with a vertical limiting slot 6. The second frame 200 is provided with a movable slider 4. The movable slider 4 is inserted into the vertical limiting slot 6.

[0040] In use, first insert the limiting block 300 vertically into the horizontal limiting component 400, and then insert the movable slider 4 horizontally into the vertical limiting slot 6. The horizontal limiting component 400 and the limiting block 300 are connected, and the movable slider 4 is connected to the vertical limiting slot 6. Through these two connections, the positional relationship is determined in three-dimensional space, ensuring the stability of the lightbox after assembly. The direct connection method is simple and easy to operate.

[0041] Reference Figure 1 , Figure 2 and Figure 5 A first mounting groove 101 is provided on the first frame 100, and a second mounting groove 201 is provided on the second frame 200. A light strip 31 is disposed within either the first mounting groove 101 or the second mounting groove 201. In this embodiment, the light strip 31 is installed within the second mounting groove 201. The light strip 31 is configured as a magnetic light strip 31, and multiple light strips 31 are electrically connected via magnetic conductive strips 32. The width of the magnetic light strip 31 is adapted to the width of the second mounting groove 201. When installing the magnetic light strip 31, it is snapped into the second mounting groove 201, making it easy to disassemble and assemble. First slots 102 are provided on both sides of the first frame 100, and second slots 202 are provided on both sides of the second frame 200. The first slots 102 and second slots 202 are used to cooperate in installing a lamp panel or lamp cloth.

[0042] Reference Figure 1 , Figure 2 and Figure 4 The first frame 100 has two parallel vertical hollow channels 103, and the limiting block 300 has two vertical rods 1. The two vertical rods 1 are inserted into the two hollow channels 103 and fixedly connected to the hollow channels 103 by screws. The first frame 100 is fixedly connected to the first frame 100 by the structural cooperation between the hollow channels 103 and the vertical rods 1 and the limiting block 300, which improves the stability of the connection between the limiting block 300 and the first frame 100.

[0043] Reference Figure 2 and Figure 4 In this embodiment of the application, the limiting block 300 includes a baffle 61 and a limiting part 62. When the limiting part 62 and the horizontal limiting member 400 are inserted, the baffle 61 and the horizontal limiting member 400 abut against each other. The limiting part 62 is provided with two vertical limiting slots 6 and a first fixing slot 111.

[0044] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4The second frame 200 has two second hollow channels 203 perpendicular to the first hollow channel 103. The horizontal limiting member 400 includes a limiting pin 7, a movable rocker arm 3, a movable slider 4, and a limiting plate 21. The limiting plate 21 has a horizontal limiting groove 2, which corresponds to the limiting block 300. When the limiting part 62 and the horizontal limiting member 400 are inserted, the baffle 61 and the top of the horizontal limiting groove 2 abut against each other. There are two limiting pins 7, which respectively cooperate with the two second hollow channels 203. One end of the limiting pin 7 is inserted into the second hollow channel 203 and fixedly connected to it, and the other end of the limiting pin 7 is fixedly connected to the limiting plate 21. The limiting pin 7 is provided with a sliding groove 11, which connects to the horizontal limiting groove 2. The movable rocker arm 3 drives the movable slider 4 to move relative to the limiting pin 7 within the sliding groove 11. Under the action of the movable rocker arm 3, the movable slider 4 slides along the sliding groove 11 and thus engages with the vertical limiting slot 6. The movable rocker arm 3 drives the movable slider 4 to move within the limiting pin 7, and the movement of the movable slider 4 is controlled by the movable rocker arm 3, thereby controlling the engagement of the movable slider 4 with the vertical limiting slot 6. This method is simple, convenient, and easy to operate.

[0045] The limiting pin 7 has a first insertion hole 16 on its side wall, the movable rocker arm 3 has a second insertion hole 17 on its side wall, and the movable slider 4 has a rotating cavity 9. The movable slider 4 also has a waist-shaped hole 8 on its side wall. The rotating shaft 5 passes through the first insertion hole 16, the waist-shaped hole 8, and the second insertion hole 17. The movable rocker arm 3 rotates around the rotating shaft 5 in the rotating cavity 9, causing the movable slider 4 to move relative to the limiting pin 7 in the sliding groove 11. During its movement, the movable slider 4 makes way for the rotating shaft 5 through the waist-shaped hole 8. The movable slider 4 has a rotating cavity 9, providing space for the movable rocker arm 3 to rotate. The movable rocker arm 3 rotates around the rotating shaft 5 in the rotating cavity 9, causing the movable slider 4 to move relative to the limiting pin 7 in the sliding groove 11. During its movement, the movable slider 4 makes way for the rotating shaft 5 through the waist-shaped hole 8. This design is simple to operate, convenient to use, and saves on production costs.

[0046] The movable rocker arm 3 includes a handle 40 and an eccentric protrusion 41, which are integrally formed. Rotating the handle 40 causes the eccentric protrusion 41 to exert a force on the inner wall of the rotating cavity 9, thus moving the movable slider 4. Rotating the handle 40 of the movable rocker arm 3 causes the eccentric protrusion 41 to exert a force on the inner wall of the rotating cavity 9, thus moving the movable slider 4. This method is simple to operate and convenient to use.

[0047] The rotating cavity 9 passes vertically through the movable slider 4, and the limiting pin 7 is provided with a relief groove 10 at the position corresponding to the rotating cavity 9 to cooperate with the rotation of the movable rocker 3.

[0048] Reference Figure 4 and Figure 6The limiting pin 7 is provided with a relief groove 10 at the position corresponding to the rotating cavity 9, allowing the movable rocker arm 3 to rotate, thus providing more rotation space for the movable rocker arm 3. When the vertical length of the rotating part of the movable rocker arm 3 is greater than the depth of the rotating cavity 9, the limiting pin 7 is provided with a relief groove 10 to enable the movable rocker arm 3 to rotate, making the rotation smoother.

[0049] The implementation principle of a lightbox frame connection structure in this application embodiment is as follows:

[0050] When assembling the light box frame, first insert the limiting block 300 vertically into the horizontal limiting groove 2 of the horizontal limiting component 400.

[0051] Before use, the movable rocker arm 3 is in an upright position, and the oblong hole 8 of the movable slider 4 is close to the inner wall of the first frame 100 and abuts against the rotating shaft 5. During use, the handle 40 of the movable rocker arm 3 is rotated downwards, causing the eccentric protrusion 41 to rotate around the rotating shaft 5 in the rotating cavity 9. This drives the movable slider 4 to move relative to the limiting pin 7 in the sliding groove 11 towards the vertical limiting slot 6. During this movement, the movable slider 4 makes way for the rotating shaft 5 through the oblong hole 8. The movable rocker arm 3 controls the movement of the movable slider 4, thereby controlling its insertion into the vertical limiting slot 6. When the movable rocker arm 3 is fully rotated down, it abuts against the rotating cavity 9, and is in a stable state. The oblong hole 8 of the movable slider 4 moves away from the inner wall of the first frame 100 and abuts against the rotating shaft 5, allowing the movable slider 4 to be fully inserted into the vertical limiting slot 6.

[0052] When the lightbox frame needs to be disassembled, rotate the movable rocker arm 3 back to the upright position. The eccentric protrusion 41 of the movable rocker arm 3 rotates around the rotating shaft 5 in the rotating cavity 9, causing the movable slider 4 to move away from the vertical limiting slot 6 relative to the limiting pin 7 in the sliding groove 11. The oblong hole 8 of the movable slider 4 abuts against the rotating shaft 5 from the inner wall near the first frame 100, and then changes to abutting against the rotating shaft 5 away from the inner wall of the first frame 100. The movable slider 4 gradually moves away from the vertical limiting slot 6. Then, pull the limiting block 300 out of the horizontal limiting groove 2 of the horizontal limiting member 400.

[0053] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 The lightbox frame connection structure also includes a support foot 500 with a reinforcing connection structure. The support foot 500 is formed by a support plate 501 and an insert plate 502 fixedly connected together. A first fixing slot 111 is provided on the limiting block 300, and the insert plate 502 passes through the first fixing slot 111 and is inserted into the first frame 100. The support foot 500 has a reinforcing connection structure, and the insert plate 502 passes through the limiting block 300 from bottom to top and inserts into the first frame 100, thus strengthening the vertical connection.

[0054] Reference Figure 1 , Figure 3 , Figure 7 and Figure 8 The first frame 100 is provided with a foot fixing member 107 and a first wire hole 106. The insert plate 502 is provided with a second wire hole 503 and a fixing hole 504. The first wire hole 106 is connected to the second wire hole 503. The foot fixing member 107 is fixedly connected to the first frame 100 and is snapped into the insert plate 502 through the fixing hole 504.

[0055] The foot fixing component 107 is provided to facilitate the fixing of the foot 500. The first wire hole 106 and the second wire hole 503 are used for passing wires. The fixing hole 504 and the foot fixing component 107 are snapped together to strengthen the fixing.

[0056] Reference Figure 3 , Figure 8 and Figure 9 The foot fixing component 107 includes a second fixing slot 108 and a wrench 109. The second fixing slot 108 and the wrench 109 are integrally formed. The insert plate 502 is inserted into the second fixing slot 108. The wrench 109 is provided with a fixing protrusion 110 corresponding to the fixing hole 504 on the side facing the fixing hole 504.

[0057] When the insert plate 502 is inserted into the first frame 100, the foot fixing member 107 has a second fixing groove 108, which fixes the upper part of the insert plate 502, making the foot fixing 500 more stable. The fixing protrusion 110 on the back of the wrench 109 is inserted into the fixing hole 504 to further fix the insert plate 502 of the foot 500.

[0058] The station plate 501 is placed under the second frame 200 and is perpendicular to the second frame in the horizontal direction. The insert plate 502 passes through the horizontal limiting groove 2 and the first fixing slot 111 in sequence, passes through the second frame 200, inserts into the first frame 100, and finally connects with the second fixing slot 108.

[0059] When it is necessary to assemble the foot 500, insert the plate 502 into the first frame 100. The plate 502 passes through the limiting block 300 and abuts against the second fixing slot 108 of the foot fixing member 107. The fixing protrusion 110 on the back of the wrench 109 is inserted into the fixing hole 504 to further fix the plate 502 of the foot 500.

[0060] When it is necessary to disassemble the foot 500, open the wrench 109 and pull out the insert plate 502 of the foot 500.

[0061] In another embodiment, this application also provides a light box, the light box including the light box frame connection structure.

[0062] When installing the lightbox frame, vertically insert the limiting block 300 and the horizontal limiting slot 2 of the horizontal limiting component 400, then turn down the movable rocker arm 3, and the movable slider 4 inserts into the vertical limiting slot 6. Through these two insertions, the positional relationship is determined in three dimensions, ensuring the stability of the assembled lightbox. The direct insertion method is simple and easy to operate. When disassembling the lightbox frame, turn up the movable rocker arm 3, separating the movable slider 4 from the vertical limiting slot 6. Then, pull the limiting block 300 out of the horizontal limiting slot 2 of the horizontal limiting component 400. This two-step installation or disassembly is simple and effortless, facilitating assembly and disassembly. When installing the foot 500, insert the insert plate 502 into the first frame 100, and the fixing protrusion 110 snaps into the fixing hole 504. The foot fixing component 107 then secures the foot 500 and strengthens the connection structure. When disassembling the foot 500, open the wrench 109 and pull out the insert plate 502 of the foot 500. Installation and disassembly are simple and effortless.

[0063] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
