[0019] In the description of the present invention, it should be noted that the terms "front", "up", "down", "left", "right", "vertical", "horizontal", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] The following is combined with Figure 1-5 The utility model is further described.

[0022] In order to solve the problems existing in the background technology, the present application proposes the following technical solution: a light box connecting device, comprising a light box main body 1, and an outer frame 2 is fixedly connected to the outside of the light box main body 1.

[0023] In a further design, a clamping member 6 is also included, and positioning blocks 15 are fixedly connected to the clamping member 6 on all four sides, and inserted into the clamping slot 4 to form a positioning fixation, and a clamping plate 3 is fixedly connected to the outer frame 2 on all four sides, and a clamping slot is provided in the clamping plate 3.

[0024] Among them, the outside of the clamping plate 3 is rotatably connected with a rotating plate 10, and the rotating plate 10 is used to assist the clamping part 6 in positioning and clamping on the outside of the clamping plate 3. The position of the rotating plate 10 corresponding to the clamping part 6 is fixedly connected with a connecting plate 9, and the outside of the connecting plate 9 is fixedly connected with a baffle 8. A positioning component is also provided on the outside of the rotating plate 10.

[0025] In order to increase the stability of the card connection, magnetic blocks are embedded on the outside of the positioning block 15 and in the card slot 4, and the magnetic blocks are arranged with opposite poles attracting each other. When the positioning block 15 is inserted into the inner chamber of the card slot 4, the magnetic blocks are attracted to each other, so the card connection is stable.

[0026] Specifically, the positioning assembly includes a positioning rod 14 connected to the outside of the rotating plate 10 and a positioning groove 18 arranged on the outside of the baffle 8. A slide groove 11 is provided on the outside of the rotating plate 10, and a return spring 13 is connected in the slide groove 11. The function of the return spring 13 is to firmly prevent the positioning rod 14 from being in contact with the positioning groove 18 to form a resistance to the rotating plate 10, so one end of the return spring 13 is fixedly connected to the positioning rod 14, and wavy spring sheets 12 are fixedly connected on both sides of the inner wall of the slide groove 11, and positioning protrusions 19 are fixedly connected on both sides of the positioning rod 14. The function of the wavy spring sheet 12 and the positioning protrusion 19 is that when the positioning rod 14 is pushed to retract, the positioning protrusion 19 is clamped in the wavy spring sheet 12, so that the position of the positioning rod 14 can be locked and stopped, which is convenient for rotating the rotating plate 10.

[0027] Among them, in order to facilitate pulling out the card connector 6, the outside is fixedly connected with a pull rod 7, so limit plates 16 are fixedly connected at both ends of the card connector 6, the inner wall of the limit plate 16 is fixedly connected with a resistance strip 17, and the outside of the card connector 3 is fixedly connected with a blocking strip 5. The plug-in card connector 6 is thick, and the resistance strip 17 and the blocking strip 5 are used to achieve the resistance limit of the pushing position.

[0028] In order for those skilled in the art to fully understand the technical solution, this embodiment is summarized as follows:

[0029] When in use, first dock the outer frames 2 of the two adjacent light box bodies 1, then take the clamping piece 6, and clamp the positioning blocks 15 at both ends of the clamping piece 6 into the clamping groove 4 until the abutment bar 17 abuts against the outside of the blocking bar 5, and then rotate the rotating plate 10 so that one end of the rotating plate 10 is located below the baffle 8, refer to the attached Figure 4 As shown in the figure, the positioning rod 14 is then pulled, so that the positioning rod 14 is clamped in the positioning groove 18 under the elastic force of the return spring 13 to form a limit for the rotating plate 10, so that the two adjacent light box bodies 1 can be quickly connected;

[0030] When disassembly is required, the positioning rod 14 only needs to be pushed to retract the positioning rod 14 into the slide groove 11, and the positioning protrusion 19 is engaged in the wavy spring sheet 12, and then the rotating plate 10 is rotated 90 degrees so that the rotating plate 10 is no longer located under the baffle 8, and then the clamping piece 6 is pulled out to remove the light box body 1.

[0031] The standard parts used in the utility model can be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the prior art.
