[0028] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] like Figures 1-4 As shown, the specific embodiment adopts the following technical solution: it includes a housing 1, a closed cover 2 and a fixing frame 3. The closed cover 2 is connected to the upper opening of the housing 1 by a latch, and the fixing frame 3 is fixedly installed on the lower part of the housing 1.

[0030] It also includes:

[0031] A support shaft 4 is rotatably inserted into the inner bottom wall of the housing 1 via bearings. A first rotating disk 5 is fixedly sleeved on the support shaft 4. Several circular grooves with equal rounded corners are provided on the first rotating disk 5, and drive disks 6 are rotatably installed in them via bearings. A lower limit mechanism 7 connected to the drive disks 6 is provided inside the support shaft 4. A synchronous rotation mechanism 8 connected to the lower limit mechanism 7 is provided inside the housing 1.

[0032] Driven shaft 9 is rotatably mounted on the inner top wall of the closed cover 2 via bearings. A plug 10 is fixedly mounted on the lower end of driven shaft 9. The plug 10 is movably inserted into the slot opened at the upper end of the support shaft 4. A second rotating disk 11 is fixedly mounted on driven shaft 9. Several circular grooves with equal rounded corners are opened on the second rotating disk 11, and driven disks 12 are rotatably mounted in each groove via bearings. An upper limit mechanism 13 is provided on driven disk 12.

[0033] Motor 14 is fixedly installed at the bottom of housing 1. The output shaft of motor 14 is connected to support shaft 4. Several support frames 15 are fixedly distributed with equal rounded corners on the inner ring wall of housing 1. Several nozzles 16 are fixedly installed on the support frames 15.

[0034] The lower limit mechanism 7 includes:

[0035] Spring 7-1 is fixedly installed inside the support shaft 4. A lifting rod 7-2 is fixedly installed at the upper end of spring 7-1. The lifting rod 7-2 is movably installed inside the support shaft 4. The upper end of the lifting rod 7-2 abuts against the insert block 10. The lower end of the lifting rod 7-2 is fixedly connected to spring 13-4.

[0036] Connecting rod 7-3, there are several connecting rods 7-3, which are distributed with equal rounded corners on the lower edge of the ring side wall of the lifting rod 7-2, and the connecting rod 7-3 is movably inserted into the strip-shaped through groove opened on the ring side wall of the support shaft 4. The connecting rod 7-3 is located below the first rotating disk 5.

[0037] Limiting frame 7-4, there are several limiting frames 7-4, which are movably installed on several driving disks 6, and the limiting frames 7-4 are rotatably mounted on the connecting rod 7-3 through shafts and bearings;

[0038] The synchronous rotation mechanism 8 includes:

[0039] The guide plate 8-1 is fixedly installed inside the housing 1, and the guide plate 8-1 is rotatably sleeved on the first rotating plate 5 through a sealed bearing. An annular frame 8-2 is fixedly installed inside the guide plate 8-1, and an internal gear ring 8-3 is fixedly installed inside the annular frame 8-2.

[0040] Gears 8-4, there are several gears 8-4, which are fixedly sleeved on several limiting frames 7-4 respectively, and gears 8-4 are meshed with internal gear rings 8-3. When the first rotating disk 5 drives the drive disk 6 to rotate in the housing 1, the meshing of gears 8-4 and internal gear rings 8-3 can make gears 8-4 drive the drive disk 6 to rotate, thereby realizing that the table legs on the drive disk 6 revolve in the housing 1 while rotating on their own axis, so that multiple table legs can be sprayed with paint from the spray nozzles 16 in a surrounding manner.

[0041] The upper limit mechanism 13 includes:

[0042] A rectangular rod 13-1, comprising several rectangular rods 13-1, is movably mounted on several driven discs 12. Limiting plates 13-2 and contact plates 13-3 are fixedly installed at the upper and lower ends of the rectangular rods 13-1, respectively.

[0043] Several springs 13-4 are movably sleeved on several rectangular rods 13-1. The upper and lower ends of each spring 13-4 are fixedly mounted on a limiting plate 13-2 and a driven disc 12, respectively. A limiting ring 17 is fixedly installed inside the closed cover 2 above the second rotating disc 11. A rubber ring 18 is fixedly installed at the bottom of the limiting plate 13-2, and the rubber ring 18 and the limiting ring 17 are in a moving contact arrangement. When the closed cover 2 is open, the springs 13-4 limit the movement of the springs 13-4. The rebound force applied by the position plate 13-2 allows the rubber ring 18 to abut against the limiting ring 17 and generate a large frictional force between them, thereby limiting the rotation of the driven plate 12 in this state. An observation window 19 is fixedly provided at the opening on the side wall of the housing 1, and a light strip 20 is fixedly provided at the bottom of the limiting ring 17. The staff can observe the spraying of paint inside the housing 1 through the observation window 19, and the light emitted by the light strip 20 can also make the spraying of paint inside the housing 1 clearer.

[0044] When using this utility model, the table legs are placed on the drive plate 6 and limited by the limiting bracket 7-4. Then, the upper opening of the housing 1 is closed by the closing cover 2. During this process, the abutment plate 13-3 will abut against the upper end of the table legs. As the closing cover 2 moves downward, the second spring 13-4 will be stretched. The downward pulling force of the second spring 13-4 on the limiting plate 13-2 can be converted into the downward pressing force of the abutment plate 13-3 on the table legs through the rectangular rod 13-1, so that the table legs are clamped and fixed between the abutment plate 13-3 and the drive plate 6. As the closing cover 2 continues to move downward, the insert block 10 will be inserted into the slot and move the lifting rod 7-2 downward, compressing the first spring 7-1. The lifting rod 7-2 drives the limiting plate 13-3 through the connecting rod 7-3. The support frame 7-4 moves downward, disengaging from the limit frame 7-4 on the table legs, thus preventing the limit frame 7-4 from obstructing the painting process. Then, the spray nozzle 16 sprays paint onto the table legs. Simultaneously, the motor 14 is started, which drives the support shaft 4 to rotate. The support shaft 4 drives the first rotating disk 5 and the insert block 10 to rotate. The insert block 10 drives the driven shaft 9 to rotate, which in turn drives the second rotating disk 11 to rotate. This achieves synchronous rotation of the first rotating disk 5 and the second rotating disk 11, allowing the clamped table legs to revolve within the housing 1. Furthermore, the meshing of the gear 8-4 and the internal gear ring 8-3 allows the limit frame 7-4 to drive the drive disk 6 to rotate, thereby achieving the rotation of the table legs during their revolve within the housing 1 and enabling uniform, circumferential spraying of the table legs.

[0045] Compared with the prior art, the beneficial effects of this utility model are:

[0046] 1. Through the cooperation of rotating disk 5, drive disk 6, lower limit mechanism 7, driven shaft 9, insert block 10, rotating disk 11, driven disk 12 and upper limit mechanism 13, the table legs can be fixed by clamping the end face of the table legs. This not only avoids obstructing the surface of the side wall of the table legs, but also makes the clamping and fixing process simple and quick.

[0047] 2. Through the cooperation of the synchronous rotation mechanism 8, the meshing of gear 8-4 and internal gear ring 8-3 can drive the limit frame 7-4 and drive plate 6 to rotate during the rotation of the first rotating disk 5, thereby realizing the rotation of several table legs during the revolution within the housing 1, so that the paint can be sprayed evenly on several table legs simultaneously.

[0048] 3. When the closed cover 2 is open, the rebound force exerted by the second spring 13-4 on the limiting plate 13-2 can cause the rubber ring 18 to abut against the limiting ring 17 and generate a large friction force between them, so as to limit the rotation of the driven plate 12 in this state.

[0049] 4. Staff can observe the paint spraying inside the housing 1 through the observation window 19, and the paint spraying inside the housing 1 can be observed more clearly through the light emitted by the light strip 20.

[0050] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. 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.
