[0021] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive of other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0022] An embodiment of the present utility model provides an automatic spraying device for a bicycle frame, as Figures 1-4As shown in the figure, it includes a spraying box 1. An L-shaped support rod 2 is welded on one inner wall of the spraying box 1. A first plug post 3 is welded at the central position of the top end of the L-shaped support rod 2. A bicycle frame 4 is arranged inside the spraying box 1. A chute 5 is opened at a position on one inner wall of the spraying box 1 close to the L-shaped support rod 2. A slider 6 is slidably connected inside the chute 5. The cross-sections of the chute 5 and the slider 6 are both T-shaped structures. A spring 7 is arranged between one inner wall of the chute 5 and one outer wall of the slider 6. A support plate 8 is welded on one outer wall of the slider 6. A second plug post 9 is welded on one outer wall of the support plate 8. A rotary cylinder 10 is fixedly connected to the central position of one outer wall of the spraying box 1 by bolts. The rotary cylinder 10 is fixedly connected to a turntable 11 through its output end on one side. A spraying rod 12 is welded on one outer wall of the turntable 11. Spraying holes 13 are opened on one outer wall of the spraying rod 12. A paint box 14 and a spraying pump 15 are fixedly connected to a position on one outer wall of the spraying box 1 close to the rotary cylinder 10 by bolts. The paint box 14 is located on one side of the spraying pump 15. The paint box 14 and the spraying pump 15 are connected and communicated through a pipeline. A universal bellows 16 is arranged between the spraying pump 15 and the turntable 11. A box door 17 is hinged on the top of the spraying box 1.

[0023] It should be noted that since the existing environmental protection spraying device for bicycle frames needs to be clamped and fixed before spraying the bicycle frame, the bicycle frame needs to be subjected to opposite extrusion to achieve clamping. It is easy to have too small clamping force resulting in insufficient clamping and difficulty in rotating the bicycle frame, and too large clamping force is likely to cause deformation of the bicycle frame and affect the structural strength. In this embodiment, by utilizing the structural characteristics of the bicycle frame 4, the first plug post 3 and the second plug post 9 can be inserted into the bicycle frame 4 to limit it. The fixing operation of the bicycle frame 4 is simple and will not cause deformation and damage to the bicycle frame 4. And by rotating the spraying rod 12 360 degrees along the bicycle frame 4, the effect of comprehensively and evenly spraying the bicycle frame 4 is achieved.

[0024] Specifically, in this embodiment, this solution mainly includes a first plug post 3 and a second plug post 9. When the bicycle frame 4 is automatically sprayed, the vertical through hole on the bicycle frame 4 is aligned with the first plug post 3, the first plug post 3 is inserted into the bicycle frame 4, the support plate 8 is pulled horizontally, the slider 6 slides in the slide groove 5, the spring 7 is compressed, the bicycle frame 4 is straightened, the support plate 8 is released, and under the action of the rebound force of the spring 7, the second plug post 9 is inserted into the horizontal through hole on the bicycle frame 4, and the bicycle frame 4 is inserted through the first plug post 3 and the second plug post 9. The position of the bicycle frame 4 is limited, the box door 17 is closed, the rotating cylinder 10 drives the turntable 11 to rotate through the output end on one side thereof, the spraying rod 12 on the turntable 11 makes a circular motion along the outer side of the bicycle frame 4, the spraying pump 15 draws the spray paint in the paint box 14 into the spraying rod 12 through the universal bellows 16, and the spraying hole 13 on the spraying rod 12 sprays the spray paint onto the bicycle frame 4. When the rotating cylinder 10 drives the turntable 11 to rotate 360 ​​degrees and then resets and rotates, it not only avoids the entanglement of the universal bellows 16, but also realizes the all-round spraying of the bicycle frame 4.

[0025] In a further preferred embodiment of the present invention, Figures 1-2 As shown, the bicycle frame 4 is provided with through holes for the first plug post 3 and the second plug post 9 to be inserted into, and the through holes are the locations for installing the front of the bicycle and the pedals.

[0026] In this embodiment, the structural characteristics of the bicycle frame 4 can be used to limit the bicycle frame 4, so that the bicycle frame 4 is unobstructed after being limited, and the spray rod 12 can be rotated 360 degrees along the bicycle frame 4 to achieve the effect of fully and evenly spraying the bicycle frame 4.

[0027] In a further preferred embodiment of the present invention, Figure 3 As shown, the spray rod 12 is a hollow structure, and the spray rod 12 and the universal bellows 16 are communicated and connected.

[0028] In this embodiment, the spray paint can enter the spray rod 12 through the universal bellows 16 .

[0029] In a further preferred embodiment of the present invention, Figure 1 and Figure 3 As shown, there is a gap between the turntable 11 and the inner wall of the spray box 1, and the gap can allow the universal bellows 16 to expand and contract.

[0030] In this embodiment, the universal bellows 16 is prevented from being damaged by pulling.
