Description

Technical Field

[0001] This invention relates to the technical field of spraying brackets, and in particular to the technical field of a spraying bracket. Background Technology

[0002] Spraying is a process for surface treatment of materials. It has a wide range of applications, from furniture and household goods to automotive products. Existing spraying brackets are relatively simple in structure and can basically meet the needs of spraying. However, to accommodate larger materials, existing spraying brackets need to be manufactured in larger sizes. While this achieves the purpose of spraying, the brackets are bulky, occupy a lot of space, and have poor compatibility with different materials. Utility model patent CN202121902556.1 discloses a metal product spraying bracket with a folding structure. By incorporating a pivot, the base rod can be easily rotated outside the device. This allows for simultaneous adjustment of the base rod's angle while adjusting the device's height. Furthermore, the base rod's height can be adjusted simultaneously with the device's height adjustment via the pivot and bearing. When not in use, the base rod can be folded along the pivot and support, reducing the device's size and making it easier for users to store. While this device achieves storage functionality, it cannot adapt to different plastic materials and is not suitable for supporting long plastic materials. Summary of the Invention

[0003] The purpose of this invention is to solve the problems in the prior art by proposing a spraying bracket that solves the problems of existing long and large spraying material brackets being unable to be folded and having poor versatility.

[0004] To achieve the above objectives, the present invention proposes a spraying bracket, comprising a folding bracket, a rod base, a lifting guide plate, a telescopic rod, a return spring, a positioning sleeve, and a positioning power cylinder. Two folding brackets are provided, each with a rod base hinged at both ends. A lifting guide plate is positioned between the opposing hinge axes of the two folding brackets. The telescopic rod passes through a set of two opposing lifting guide plates. A return spring is positioned between the set of two lifting guide plates to push the telescopic rod back to its original position. A positioning sleeve for limiting the lifting and lowering of the telescopic rod is fitted onto the lower lifting guide plate of the set of two lifting guide plates. A positioning power cylinder for driving the positioning sleeve to its working state is provided on the lifting guide plate.

[0005] Preferably, the folding bracket includes an X-shaped frame and a V-shaped frame, with the X-shaped frame hinged at both ends and the lower ends of the X-shaped frame hinged to the two ends of the V-shaped frame.

[0006] Preferably, the X-frame includes X-shaped cross rods and X-shaped cross hinge shafts, with two X-shaped cross rods forming a group, and the two X-shaped cross rods being hinged together at the middle via the X-shaped cross hinge shafts.

[0008] Preferably, the upper and lower hinge shafts at the end of the X-shaped frame form a group, and the two lifting guide plates on the two hinge shafts in the same group form a group, with the telescopic rod passing through the two lifting guide plates in the same group.

[0009] Preferably, the X-shaped cross hinge shaft and the V-shaped cross hinge shaft located directly below it form a group, and the lifting guide plates on the X-shaped cross hinge shaft and the V-shaped cross hinge shaft in the same group form a group, and the telescopic rod passes through the two lifting guide plates in the same group.

[0010] Preferably, the rod base includes a rod body, a lifting sliding sleeve, a positioning screw sleeve, and a traveling wheel. A lifting sliding sleeve is fixedly provided on the upper part of the rod body, and a lifting sliding sleeve is movably provided on the lower part of the lifting sliding sleeve.

Detailed Implementation

[0017] See Figure 1 , Figure 2 , Figure 3 and Figure 7This invention discloses a spraying bracket, comprising a folding bracket 1, a rod base 2, a lifting guide plate 3, a telescopic rod 4, a return spring 5, a positioning sleeve 6, and a positioning power cylinder 7. Two folding brackets 1 are present. Rod bases 2 are hinged at both ends of each folding bracket 1. A lifting guide plate 3 is positioned between the opposing hinge axes of the two folding brackets 1. The telescopic rod 4 passes through a set of two vertically opposing lifting guide plates 3. A return spring 5 is positioned between the two lifting guide plates 3 to push the telescopic rod 4 back to its original position. A positioning sleeve 6 is fitted onto the lower lifting guide plate 3 of the set of two lifting guide plates 3 to limit the lifting of the telescopic rod 4. The base plate 3 is equipped with a positioning power cylinder 7 for driving the positioning sleeve 6 to work. By setting two lifting guide base plates 3 as a group, the telescopic rod 4 can be kept in a vertical state. The material is placed on the array of telescopic rods 4. Since the telescopic rod 4 can extend and retract, when the shape of the array of telescopic rods 4 matches the shape of the material, the positioning power cylinder 7 drives the positioning sleeve 6 to position the telescopic rod 4 and restrict its up and down movement. The folding bracket 1 can be folded. By setting the telescopic rods 4 in a matrix, the material can maintain its shape. The coated material will not wrinkle due to the stretching of the surface coating caused by the deformation of the material.

[0018] like Figures 2-4 As shown, the folding bracket 1 includes an X-shaped frame 11 and a V-shaped frame 12. The X-shaped frame 11 is hinged end to end, and the two lower ends of the X-shaped frame 11 are hinged to the two ends of the V-shaped frame 12. By setting the V-shaped frame 12 below the X-shaped frame 11, it can be ensured that all the hinge axes are in a group, thus ultimately ensuring that the telescopic rod 4 will not rotate. The X-shaped frame 11 includes X-shaped cross rods 111 and X-shaped cross hinge shafts 112. The two X-shaped cross rods 111 are in a group of two, and the middle of the two X-shaped cross rods 111 are hinged together by the X-shaped cross hinge shafts 112. Figures 2-3 and Figure 5 As shown, the V-shaped frame 12 includes V-shaped cross rods 121 and V-shaped cross hinge shafts 122. The V-shaped cross rods 121 are arranged in pairs, with their lower ends hinged together via the V-shaped cross hinge shafts 122. The upper and lower hinge shafts at the end of the X-shaped frame 11 form a group, and the two lifting guide plates 3 on the same group of hinge shafts form another group. The telescopic rod 4 passes through the two lifting guide plates 3 in the same group. By ensuring that the upper and lower hinge shafts at the end of the X-shaped frame 11 are grouped together, the telescopic rod 4 passing through the two lifting guide plates 3 can always remain vertical, regardless of whether the frame is in its open, semi-open, or fully open state. Figures 2-5As shown, the X-shaped cross hinge 112 and the V-shaped cross hinge 122 located directly below it form a group. The lifting guide plates 3 on the X-shaped cross hinge 112 and the V-shaped cross hinge 122 in the same group form a group. The telescopic rod 4 passes through the two lifting guide plates 3 in the same group. By setting the V-shaped cross hinge 122 and the X-shaped cross hinge 112 as a group, it can be ensured that the telescopic rod 4 passing through the two lifting guide plates 3 always remains in a vertical state, regardless of whether the bracket is in the open state or the semi-open state.

[0019] like Figure 2 and Figure 6 As shown, the rod base 2 includes a rod body 21, a lifting sliding sleeve 22, a positioning screw sleeve 23, and a traveling wheel 24. A lifting sliding sleeve 22 is fixedly mounted on the upper part of the rod body 21, and a lifting sliding sleeve 22 is movably mounted on the lower part of the lifting sliding sleeve 22. A positioning screw sleeve 23 is threaded onto the rod body 21, and the upper end of the positioning screw sleeve 23 contacts the lower end of the lifting sliding sleeve 22 located at the lower part of the rod body 21. A traveling wheel 24 is provided at the lower end of the rod body 21. A hinge seat 221 for hinged connection with the folding bracket 1 is provided on the positioning screw sleeve 23. By rotating the positioning screw sleeve 23, the height of the lifting sliding sleeve 22 at the lower part of the rod body 21 is adjusted, thereby changing the angle of the X-shaped frame 11 and the V-shaped frame 12, ultimately achieving the purpose of adjusting the length of the folding bracket 1. Figure 9 As shown, the lifting guide plate 3 is provided with a guide hole 31, and the telescopic rod 4 is slidably disposed in the guide hole 31. Although the lifting guide plate 3 is connected to the hinge shaft, because the telescopic rod 4 passes through the two lifting guide plates 3 arranged vertically, the lifting guide plate 3 will remain horizontal and will not rotate. Figure 10 As shown, a side support plate 41 is provided on the upper side of the telescopic rod 4, and a reset limiting plate 42 is provided on the upper part of the telescopic rod 4. The lower surface of the reset limiting plate 42 contacts the end of the reset spring 5. A positioning tooth 43 is provided on the lower part of the telescopic rod 4. The telescopic rod 4 located at the edge of the material, the side support plate 41 can support the edge of the material, the upper end of the telescopic rod 4 restricts the material from moving to one side, and the telescopic rod 4 located below the material supports the material by pressing against it with its upper end. Figure 8 As shown, the positioning sleeve 6 is provided with a limiting hole 61, the telescopic rod 4 passes through the limiting hole 61, and a limiting plate 62 is provided on one side of the limiting hole 61. The limiting plate 62 engages with the positioning tooth 43. By inserting the limiting plate 62 into the positioning tooth 43, the up and down movement of the telescopic rod 4 is restricted.

[0020] The working process of this invention is as follows: The material is placed on an array of telescopic rods 4. Since the telescopic rods 4 can extend and retract, when the shape of the array of telescopic rods 4 matches the shape of the material, the positioning power cylinder 7 drives the positioning sleeve 6 to position the telescopic rods 4 and restrict their vertical movement. The folding bracket 1 can be folded. By setting the telescopic rods 4 in a matrix, the material can maintain its shape. The coated material will not wrinkle due to stretching caused by material deformation. The height of the lifting sliding sleeve 22 at the bottom of the rod body 21 can be adjusted by rotating the positioning screw sleeve 23, thereby changing the angle of the X-shaped frame 11 and the V-shaped frame 12, ultimately achieving the purpose of adjusting the length of the folding bracket 1. The side support plate 41 of the telescopic rods 4 located at the edge of the material can support the edge of the material. The upper end of the telescopic rods 4 restricts the material from moving to one side. The telescopic rods 4 located below the material support the material by pressing against the upper end of the telescopic rods 4. By using the limiting plate 62 inserted into the positioning teeth 43, the vertical movement of the telescopic rods 4 is restricted, thereby restricting the array of telescopic rods 4 to maintain a shape similar to that of the material.

[0021] The present invention provides a spraying bracket that operates during the spraying process.

[0022] This invention provides a spraying bracket, which, by applying a folding bracket 1, a rod base 2, a lifting guide plate 3, a telescopic rod 4, a return spring 5, a positioning sleeve 6, and a positioning power cylinder 7 to the spraying bracket, enables the spraying to be directly used for bearing larger, longer, and softer materials, preventing large deformation of the materials. At the same time, the bracket can be folded after use, occupying little space and adapting to materials of different shapes, thus having strong adaptability.
