[0026] See also Figure 1-5The utility model provides a combined connection and fixing structure for an exhibition cabinet, including a cabinet 1, which is used to place exhibits inside. Both sides of the top of the inner wall of the cabinet 1 are fixedly connected to a vertical seat 16, and the bottom end of the inner wall of the vertical seat 16 is rotatably connected to a threaded rod 17 through a bearing. The top of the threaded rod 17 is threadedly connected to a lifting cylinder 18, and the top of the lifting cylinder 18 is fixedly connected to a plug-in block 2, which can be adjusted in height. Locking grooves 3 are provided on both sides of the plug-in block 2, and the bottom of the vertical seat 16 is rotatably connected to a rotating member 21 through a bearing 2. Both sides of the bottom end of the inner wall of the cabinet 1 are fixedly connected to a plug-in seat 5, and mounting grooves 6 are provided on both sides of the inner wall of the plug-in seat 5. The inner wall of the mounting groove 6 is fixedly connected with a spring piece 7, and one end of the spring piece 7 is fixedly connected to a locking block 8 for locking the cabinet 1 after assembly. An inclined groove 9 is provided in the middle of the top of the locking block 8, and a through rod 10 is inserted on both sides of the top of the plug-in seat 5. The tops of the two through rods 10 are fixedly connected with a pressing block 11 for unlocking operation.

[0027] During use, when assembling the cabinet bodies 1 of the exhibition display cabinet, pressing the pressing block 11 drives the two penetrating rods 10 to move downward. With the cooperation of the inclined grooves 9, the locking blocks 8 on both sides can be squeezed to retract into the installation grooves 6. Then, the two plug-in blocks 2 above the other cabinet body 1 are inserted into the two plug-in seats 5 in the cabinet body 1. Under the action of the spring piece 7, the locking block 8 will pop out and be stuck in the locking groove 3 of the plug-in block 2, thereby fixing the position of the two cabinet bodies 1 in combination.

[0028] A bevel gear 19 is fixedly sleeved at the bottom of the threaded rod 17, and one end of the rotating member 21 passes through the inner wall of the vertical seat 16 and is fixedly connected to a bevel gear 20, and the bevel gear 19 is meshed with the bevel gear 20 for transmission. The top of the vertical seat 16 is located above the rotating member 21 and is fixedly connected to a connecting member 27, and a latch 28 is inserted through the surface of the connecting member 27. A number of sockets 29 are evenly provided on the surface of the rotating member 21, and the bottom end of the latch 28 is inserted into the inside of one of the sockets 29 to play a locking role. Slide grooves 23 are provided on both sides of the inner wall of the vertical seat 16, and sliders 22 are fixedly connected on both sides of the bottom of the lifting cylinder 18, and the slider 22 is slidably connected to the inner wall of the slide groove 23 to play a limiting and guiding role.

[0029] When in use, by rotating the rotating parts 21 at the bottom of the vertical seats 16 on both sides, the threaded rod 17 can be driven to rotate with the cooperation of the bevel gear 20 and the bevel gear 1 19. Since the top of the threaded rod 17 is threadedly connected to the inner wall of the lifting cylinder 18, and under the guidance of the slider 22 and the slide groove 23, the lifting cylinder 18 will move vertically, changing the height of the upper plug-in block 2, so that the distance between the upper and lower cabinets 1 after the combination can be adjusted. After the adjustment is completed, the pin 28 is inserted into the socket 29 on the rotating part 21 to play a locking role, preventing the plug-in block 2 from falling back.

[0030] A connecting groove 12 is provided on the back of the pressing block 11, and a spring 13 is fixedly connected to the inner wall of the connecting groove 12. One end of the spring 13 is fixedly connected to the limiting block 14, and one end of the top of the socket 5 is fixedly connected to the limiting ring 15, which can lock the position of the pressing block 11. The four corners of the inner wall of the cabinet 1 are fixedly connected with reinforcing ribs 26 to improve the structural strength. Openings 4 are provided on both sides of the bottom end of the cabinet 1 to provide penetration space. A groove 24 is provided in the middle of one end of the cabinet 1, and a convex strip 25 is provided in the middle of the other end of the cabinet 1 to facilitate docking.

[0031] When in use, when the pressing block 11 is pressed downward, the limit block 14 pops out under the action of the spring 13 and is stuck in the limit ring 15, which can lock the position of the pressing block 11, so that the locking block 8 remains retracted in the installation groove 6, which is convenient for the assembly of the cabinet 1. The opening 4 is used for the insertion of the plug-in block 2. The grooves 24 and ridges 25 are convenient for the splicing and alignment between the two adjacent cabinets 1 on the left and right. The reinforcement ribs 26 can improve the structural strength of the cabinet 1 and make it not easy to be damaged.

[0032] When in use, the utility model provides a combined connection and fixing structure for exhibition cabinets. When the cabinets 1 of the exhibition cabinet are assembled, the limit blocks 14 on the back of the pressing blocks 11 on both sides are squeezed into the connecting grooves 12, and then the pressing blocks 11 are pressed downward to drive the two penetrating rods 10 to move downward. With the cooperation of the inclined grooves 9, the locking blocks 8 on both sides can be squeezed to retract into the installation grooves 6, and the limit blocks 14 will pop out and be stuck in the limiting rings 15 under the action of the springs 13, locking the position of the pressing blocks 11, and then the two plug-in blocks 2 above one cabinet 1 are inserted into the two plug-in seats 5 in the cabinet 1, and the limit blocks 14 are pressed again into the connecting grooves 12. Under the action of the spring pieces 7, the locking blocks 8 will pop out and be stuck in the locking grooves 3 of the plug-in blocks 2, playing a locking role. The pressing block 11 will be squeezed and moved upward, thereby combining and fixing the positions of the two cabinets 1. The operation is convenient and no tools are required. The assembly efficiency is high. By rotating the rotating parts 21 at the bottom of the vertical seats 16 on both sides, the threaded rod 17 can be driven to rotate with the cooperation of the bevel gear 20 and the bevel gear 1 19. Since the top of the threaded rod 17 is threadedly connected to the inner wall of the lifting cylinder 18, and under the guidance of the slider 22 and the slide groove 23, the lifting cylinder 18 will move vertically to change the height of the upper plug-in block 2, so that the distance between the upper and lower cabinets 1 after the combination can be adjusted, and the display height of the items can be changed with good flexibility. After the adjustment is completed, the pin 28 is inserted into the socket 29 on the rotating part 21 to play a locking role to prevent the plug-in block 2 from falling back.
