Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described by referring to the drawings are exemplary only for explaining the present utility model and should not be construed as a limitation of the present utility model.

[0026] When repairing and spraying automotive workpieces, they need to be placed on a bracket. In the related art, since the size of the bracket for supporting the workpiece and the position of the positioning pins are fixed, it cannot be applied to workpieces of different vehicle models, resulting in poor versatility.

[0027] The following refers to Figure 1 Describe the spraying bracket according to an embodiment of the present invention.

[0028] The spraying bracket 1 according to the present invention includes a bracket body 11, a first bracket 12, a second bracket 13, a first positioning member 14 and a second positioning member 15. The bracket body 11 extends in a first direction; the first bracket 12 and the second bracket 13 are respectively arranged at both ends of the bracket body 11, and at least one of the first bracket 12 and the second bracket 13 is movable relative to the bracket body 11 in the first direction; the first positioning members 14 are configured in multiple numbers and are respectively movably arranged on the first bracket 12, and the multiple first positioning members 14 can be selectively moved away from or closer to each other in a second direction; the second positioning members 15 are configured in multiple numbers and are respectively movably arranged on the second bracket 13, and the multiple second positioning members 15 can be selectively moved away from or closer to each other in the second direction; wherein, the first direction is orthogonal to the second direction.

[0029] The spraying bracket 1 according to the present invention is provided with a bracket body 11. The bracket body 11 can support the entire spraying bracket 1. The bracket body 11 extends in a first direction. As Figure 1 shown, the first bracket 12 and the second bracket 13 are respectively arranged at both ends of the bracket body 11 in the first direction. The first bracket 12 and the second bracket 13 can be used to support the workpiece to be sprayed. When repairing and spraying vehicle workpieces, the workpiece can be placed on the tops of the first bracket 12 and the second bracket 13. The first bracket 12 and the second bracket 13 support the workpiece simultaneously, improving the stability of the workpiece during spraying. After the workpiece is placed on the spraying bracket 1, the first positioning member 14 and the second positioning member 15 can respectively limit the workpiece in the second direction, further improving the stability of the workpiece during spraying.

[0030] At least one of the first bracket 12 and the second bracket 13 is movable relative to the bracket body 11 in the first direction, which enables the bracket to adapt to spraying workpieces of different lengths. At the same time, the multiple first positioning members 14 and the multiple second positioning members 15 are respectively movably arranged on the first bracket 12 and the second bracket 13, so that the multiple first positioning members 14 can be moved away from or closer to each other in the second direction. Similarly, the multiple second positioning members 15 can be moved away from or closer to each other in the second direction. The arrangement of the first positioning member 14 and the second positioning member 15 enables the spraying bracket 1 to adapt to workpieces of different widths. As Figure 1As shown, the first bracket 12 is movable. By adjusting the position of the first bracket 12 in the first direction and the positions of the first positioning member 14 and the second positioning member 15 in the second direction, the spraying bracket 1 can adapt to workpieces of more sizes, improving the flexibility and versatility of the spraying bracket 1, so that the spraying bracket 1 does not need to be replaced when spraying different workpieces, thus improving the production efficiency.

[0031] According to an embodiment of the present invention, a first sliding fit portion extending in the first direction is provided on the bracket body 11, and a second sliding fit portion slidably fitted with the first sliding fit portion is provided on the first bracket 12. The arrangement of the first sliding fit portion and the second sliding fit portion enables the first bracket 12 to smoothly move relative to the bracket body 11 in the first direction, so that the length of the spraying bracket 1 can be flexibly adjusted according to the specific size of the workpiece to be sprayed, further enhancing the adaptability of the spraying bracket 1. The first sliding fit portion and the second sliding fit portion are slidably fitted, improving the stability of the first bracket 12 during movement and making the position adjustment process of the first bracket 12 simpler.

[0032] According to an embodiment of the present invention, the first sliding fit portion is configured as a plurality of spaced apart in the second direction, and the second sliding fit portion corresponds to the first sliding fit portion one by one. The spraying bracket 1 is provided with a plurality of first sliding fit portions spaced apart in the second direction, and the plurality of first sliding fit portions and the second sliding fit portion correspond to each other one by one, enabling the first bracket 12 to form a stable sliding connection with the bracket body 11 at multiple points, enhancing the overall stability of the bracket and reducing shaking and deformation during spraying. The arrangement of the plurality of sliding fit portions enables the first bracket 12 to better disperse the weight and pressure when carrying the spraying workpiece, helping to improve the load-bearing capacity of the bracket and enabling it to adapt to heavier or larger spraying workpieces.

[0033] According to an embodiment of the present invention, the first sliding fit portion is configured as a first sleeve 113, and the second sliding fit portion is configured as a slide bar. The first sleeve 113 sleeves at least part of the outer periphery of the slide bar, and the slide bar is slidable relative to the first sleeve 113. The structures of the first sliding fit portion and the second sliding fit portion affect the adjustment of the size of the spraying bracket 1 in the first direction. Specifically, the spraying bracket 1 configures the first sliding fit portion as a sleeve and the second sliding fit portion as a slide bar, and at least part of the slide bar is slidably disposed within the sleeve. By adopting the combination of the sleeve and the slide bar, a sliding connection between the first bracket 12 and the bracket body 11 is achieved, and at the same time, this structure is relatively simple and easy to manufacture and assemble. The fit between the slide bar and the sleeve enables the first bracket 12 to smoothly slide on the bracket body 11, reducing friction and resistance and making the adjustment easier. The way the slide bar slides inside the sleeve can prevent the first bracket 12 from shaking or shifting during sliding, enhancing the overall stability of the bracket.

[0034] According to an embodiment of the present utility model, the bracket body 11 includes a base 111 and a support rod 112. The support rods 112 are configured to be multiple and are arranged around the outer periphery of the base 111. A first sleeve 113 is provided at the top of the support rod 112. The base 111 can be placed on the ground. A plurality of support rods 112 are arranged around the base 111. The support rods 112 can support the first sleeve 113. The plurality of support rods 112 are arranged around the base 111 to form a stable support structure, enabling the spraying bracket 1 to stably support the spraying workpiece and reducing the shaking and tilting during the spraying process. The design of the plurality of support rods 112 improves the load-bearing capacity of the bracket body 11, enabling it to adapt to heavier or larger spraying workpieces and avoiding deformation or damage of the spraying bracket 1 due to excessive workpiece weight. In addition, the design of the plurality of support rods 112 also reduces the stress concentration at a single support point, making the bracket body 11 more durable and extending its service life.

[0035] According to an embodiment of the present utility model, the first bracket 12 includes: a first rod body 121, a first connecting rod 122, and a second sleeve 123. The first rod body 121 extends in the second direction, and a plurality of sliding rods are arranged at intervals in the extending direction of the first rod body 121; the first connecting rods 122 are configured to be multiple and extend in the third direction, and the plurality of first connecting rods 122 are arranged at intervals in the extending direction of the first rod body 121; the second sleeve 123 is provided at the top of the first connecting rod 122 and extends in the second direction, and a plurality of first positioning members 14 are respectively slidably arranged in the second sleeve 123; wherein, the third direction is orthogonal to the first direction and the second direction respectively.

[0036] Specifically, the first rod body 121 extends in the second direction and connects the plurality of spaced-apart sliding rods, such that when the first bracket 12 moves, the plurality of sliding rods can slide in the corresponding first sleeves 113 simultaneously, ensuring the smooth movement of the first bracket 12 when adjusting its position. The first connecting rod 122 extends in the third direction, and the second sleeve 123 is provided at the top of the first connecting rod 122. Here, the third direction is orthogonal to the first direction and the second direction respectively. Therefore, it can be simply understood that: the first connecting rod 122 supports the second sleeve 123 in terms of height. The arrangement of the plurality of first connecting rods 122 improves the structural strength of the first bracket 12, and further improves the load-bearing capacity of the spraying bracket 1 for supporting the workpiece to be sprayed. The second sleeve 123 extends in the second direction, providing a slidable installation space for the plurality of first positioning members 14, enabling the first positioning members 14 to make precise position adjustments along the second direction as needed to adapt to workpieces of different sizes and shapes. At the same time, since the first positioning members 14 are slidably arranged at both ends of the second sleeve 123, the first positioning members 14 can quickly adjust their positions by sliding, improving the efficiency of the spraying operation.

[0037] According to an embodiment of the present utility model, the first positioning member 14 includes a first sliding portion 141 and a first limiting portion 142. At least a part of the first sliding portion 141 is slidably disposed within the second sleeve 123; the first limiting portion 142 is disposed on the first sliding portion 141 and protrudes in a direction away from the first sliding portion 141. The first sliding portion 141 can be understood as the structure in the first positioning member 14 that cooperates with the second sleeve 123 to realize the position adjustment of the first positioning member 14. The first sliding portion 141 is slidably disposed within the second sleeve 123, so that the first positioning member 14 can slide along the extending direction of the second sleeve 123 to adjust the position of the first positioning member 14, ensuring the smoothness of the movement of the first positioning member 14 when adjusting the position and the accuracy of the position adjustment, and avoiding the situation of deviation when the first positioning member 14 adjusts the position. The first limiting portion 142 is disposed on the first sliding portion 141 and protrudes in a direction away from the first sliding portion 141. As Figure 1 shown, at this time, the second limiting portion 152 extends in the third direction away from the base 111. After assembling the workpiece, the first limiting portion 142 can limit the workpiece to be sprayed in the second direction, ensuring that the workpiece is stable during spraying, without shaking and deviation, and thus ensuring the spraying quality.

[0038] According to an embodiment of the present utility model, the second bracket 13 includes: a second rod body 131, second connecting rods 132, and a third sleeve 133. The second rod body 131 extends in the second direction, and the second rod body 131 is connected to a plurality of first sleeves 113; the second connecting rods 132 are configured to be multiple and extend in the third direction. The plurality of second connecting rods 132 are spaced apart in the extending direction of the second rod body 131; the third sleeve 133 is disposed at the top of the second connecting rod 132 and extends in the second direction. The plurality of second positioning members 15 are respectively slidably disposed within the third sleeve 133.

[0039] Specifically, the second rod body 131 extends in the second direction and connects a plurality of first sleeves 113 spaced apart from each other, improving the connection strength between the bracket body 11 and the second bracket 13 and ensuring the smooth movement of the second bracket 13 when adjusting its position. The second connecting rod 132 extends in the third direction, and the third sleeve 133 is disposed at the top of the second connecting rod 132, that is, the second connecting rod 132 supports the third sleeve 133 in terms of height. The arrangement of a plurality of second connecting rods 132 improves the structural strength of the second bracket 13, and further improves the load-bearing capacity of the spraying bracket 1 for supporting the workpiece to be sprayed. The third sleeve 133 extends in the second direction, providing a slidable mounting space for a plurality of second positioning members 15, enabling the second positioning members 15 to make precise position adjustments in the second direction as needed to adapt to workpieces of different sizes and shapes. At the same time, since the second positioning members 15 are slidably disposed at both ends of the third sleeve 133, the second positioning members 15 can quickly adjust their positions by sliding, improving the efficiency of the spraying operation.

[0040] According to an embodiment of the present invention, the second positioning member 15 includes: a second sliding portion 151 and a second limiting portion 152. At least a part of the second sliding portion 151 is slidably disposed within the third sleeve 133; the second limiting portion 152 is disposed on the first sliding portion 141 and protrudes in a direction away from the second sliding portion 151. The second sliding portion 151 can be understood as the structure in the second positioning member 15 that cooperates with the third sleeve 133 to achieve the position adjustment of the second positioning member 15. The second sliding portion 151 is slidably disposed within the third sleeve 133, enabling the second positioning member 15 to slide along the extending direction of the third sleeve 133 to adjust the position of the second positioning member 15, ensuring the smooth movement and precise position adjustment of the second positioning member 15 when adjusting its position, and avoiding the situation of deviation when the second positioning member 15 adjusts its position. The second limiting portion 152 is disposed on the second sliding portion 151 and protrudes in a direction away from the second sliding portion 151. As Figure 1 shown, at this time, the second limiting portion 152 extends in the third direction away from the base 111. After assembling the workpiece, the second limiting portion 152 can limit the workpiece to be sprayed in the second direction, ensuring that the workpiece is stable during spraying without shaking and deviation, and thus ensuring the spraying quality.

[0041] According to an embodiment of the present utility model, the second sleeve 123 is configured as a polygonal sleeve, and the first sliding portion 141 is configured as a prism with the same cross-section as the polygonal sleeve; the third sleeve 133 is configured as a polygonal sleeve, and the second sliding portion 151 is configured as a prism with the same cross-section as the polygonal sleeve. The second sleeve 123 is configured as a polygonal sleeve, and the first sliding portion 141 is configured as a prism corresponding to the polygonal sleeve, so that the first sliding portion 141 will not rotate when cooperating with the second sleeve 123, ensuring the stability of the first positioning member 14. Similarly, the third sleeve 133 is configured as a polygonal sleeve, and the second sliding portion 151 is configured as a prism corresponding to the polygonal sleeve, so that the second sliding portion 151 will not rotate when cooperating with the third sleeve 133, ensuring the stability of the second positioning member 15.

[0042] In some embodiments, the positions of the first limiting portion 142 and the second limiting portion 152 can be adjusted according to the size of the workpiece to be sprayed actually. For example, when the size of the workpiece is too large, the positions of the first limiting portion 142 and the second limiting portion 152 can be adjusted to protrude towards the base 111 in the third direction, or the positions of the first limiting portion 142 and the second limiting portion 152 can be adjusted to extend in the first direction. In this way, the influence of the first limiting portion 142 and the second limiting portion 152 on the assembly of large-sized workpieces can be avoided, further increasing the size range of the spraying bracket 1 adapted to the workpiece to be sprayed, and improving the versatility and flexibility of the spraying bracket 1.
