Based on the description of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present invention.

[0032] The terms "upper", "lower", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the invention is usually placed during use. It is only for the convenience of description and simplification of the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0033] The term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, in addition to the elements listed, and may also include other elements not expressly listed.

[0034] Please refer to Figures 1 - 3 , the present utility model discloses a spraying fixture, which includes a bottom plate 10 and a cover plate 20 located above the bottom plate 10. A clamping buckle 21 is provided on the cover plate 20, and a clamping groove 13 for buckling the clamping buckle 21 is provided on the bottom plate 10. The clamping buckle 21 is clamped in the clamping groove 13 to fix the cover plate 20 on the bottom plate 10.

[0035] Please refer to Figure 1 , Figure 8 and Figure 9 , the clamping buckle 21 includes a clamping arm connected to the cover plate 20 and a clamping portion protruding from the inner side wall of the clamping arm. The clamping arm is received in the clamping groove 13, and the clamping portion is buckled on the bottom surface of the bottom plate 10. The clamping portion includes a guiding surface 211 connected to the edge of the inner side wall of the clamping arm, a protruding surface 213 connected to the guiding surface 211, a clamping surface 212 connected to the protruding surface 213 and the inner side wall, and a detachable surface 214 located on one side of the protruding surface 213 and connected to the guiding surface 211, the protruding surface 213 and the clamping surface 212. And the width L1 of the projection of the detachable surface 214 on the inner side wall of the clamping arm in the same width direction is less than or equal to half of the width L2 of the inner side wall of the clamping arm. In this embodiment, the width L1 of the projection of the detachable surface 214 on the inner side wall of the clamping arm is equal to half of the width L2 of the inner side wall of the clamping arm.

[0036] Furthermore, please refer to Figures 10 - 13 , the detachable surface 214 is disposed at an angle β with the protruding surface 213, and the angle β is 160° to 170°. The clamping surface 212 is disposed at an angle α with the inner side wall of the clamping arm, and the angle α is 120° to 145°. In this embodiment, the angle α is designed as 120°, and the angle β is designed as 165°.

[0037] When it is necessary to cover the cover plate 20 onto the bottom plate 10, the clamping buckle 21 is inserted into the clamping groove 13 along the guiding surface 211. At this time, the clamping buckle 21 elastically expands outwards, and finally when the protruding surface 213 slides past the clamping groove 13, the clamping surface 212 abuts against the lower surface of the bottom plate 10. At this time, the clamping buckle 21 restores its deformation and fixes the cover plate 20 on the bottom plate 10.

[0038] When it is necessary to remove the cover plate 20 from the bottom plate 10, the snap buckle 21 is elastically expanded outward by an external force, and the bottom wall of the snap groove 13 is abutted against the easy-to-remove surface 214. Then, it slides along the easy-to-remove surface 214 and enters the guiding surface 211 until the bottom plate 10 disengages from the guiding surface 211. At this time, the cover plate 20 is separated from the bottom plate 10.

[0039] Furthermore, in this embodiment, through the design that the included angle α between the clamping surface 212 and the inner side wall of the clamping arm is 120°, when the cover plate 20 disengages from the bottom plate 10, the bottom wall of the snap groove 13 slides along the clamping surface 212. At the same time, the snap buckle 21 expands outward and abuts against the easy-to-remove surface 214. Then, it slides along the easy-to-remove surface 214 to the guiding surface 211 and finally disengages from the guiding surface, separating the cover plate 20 from the bottom plate 10.

[0040] Through the design of the snap buckle 21 of the present utility model, it can effectively avoid the problems of difficult removal or breakage of the snap buckle 21 when the cover plate 20 is removed from the bottom plate 10. It not only facilitates the disassembly and assembly of the spraying fixture but also avoids property losses caused by frequent replacement and maintenance.

[0041] Please refer to Figure 3 and Figure 4 , a stop block 18 is provided at the notch position of the snap groove 13 on the lower surface of the bottom plate 10, and the stop block 18 is provided with a stop surface that cooperates with the clamping surface 212. When the snap buckle 21 is buckled in the snap groove 13, the clamping surface 212 abuts against the stop surface of the stop block 18. In this embodiment, the stop surface and the clamping surface 212 are arranged parallel to each other.

[0042] Furthermore, please refer to Figures 5 - 7 , the spraying fixture includes several clamping buckles 21 distributed along the circumference of the cover plate 20. In this embodiment, the spraying fixture includes 6 clamping buckles 21. Among them, two clamping buckles 21 are provided on each of the two relatively long sides of the cover plate 20, and one clamping buckle 21 is provided on each of the two relatively short sides of the cover plate 20. And the adjacent clamping buckles 21 on the same side of the cover plate 20 are arranged in a mirror image, and any two adjacent clamping buckles 21 arranged along the circumference of the cover plate 20 are arranged in a mirror image.

[0043] In this embodiment, by providing a plurality of the clamping latches 21 around the periphery of the cover plate 20, and the plurality of the clamping latches 21 being evenly spaced apart, the clamping force of the spraying fixture can be effectively maintained in all directions and the clamping force is evenly distributed around the periphery of the cover plate 20, making the snap connection between the cover plate 20 and the bottom plate 10 more stable.

[0044] Please refer to Figure 3 and Figure 4 , the spraying fixture further includes a plurality of the clamping latches 21 protruding from the middle of the cover plate 20, and a protective cover 16 for protecting the clamping latches 21 is provided on the lower surface of the bottom plate 10 around the middle clamping groove 13. More specifically, the protective cover 16 is provided with a receiving groove 17 for receiving the clamping portion of the clamping latch 21.

[0045] In this embodiment, by providing the clamping latches 21 in the middle of the cover plate 20, it effectively prevents the cover plate 20 and the bottom plate 10 in the middle from separating during spraying, resulting in an excessive distance between the cover plate 20 and the bottom plate 10 in the middle and ultimately causing spraying failure. Thus, the snap connection between the cover plate 20 and the bottom plate 10 is further strengthened by the clamping latches 21 in the middle.

[0046] Please refer to Figure 1 , Figure 3 and Figure 12 , the cover plate 20 is provided with a holding portion 22 protruding outward from the outer periphery of the clamping latch 21. When the cover plate 20 needs to be removed from the bottom plate 10, by pulling the holding portion 22, the bottom plate 10 can be separated from the cover plate 20 along the clamping surface 212, the easily detachable surface 214, and the guiding surface 211.

[0047] Please refer to Figure 2 , Figure 5 and Figure 10 , the bottom plate 10 is provided with positioning holes 14 for positioning the cover plate 20, and the cover plate 20 is provided with positioning posts 24 protruding corresponding to the positioning holes 14 and inserted into the positioning holes 14. When the cover plate 20 is closed on the bottom plate 10, the positioning posts 24 are inserted into the positioning holes 14 to play a positioning role. More specifically, the distribution of the positioning posts 24 and the positioning holes 14 is asymmetrically arranged, which can effectively prevent the product in the spraying fixture from being damaged when the cover plate 20 is closed on the bottom plate 10 when the cover plate 20 rotates relative to the bottom plate 10 by a certain angle.

[0048] Please refer to Figures 1 - 3, strip-shaped upper fixing strips 11 and lower fixing strips 15 are distributed on the upper surface and the lower surface of the bottom plate 10. The upper fixing strips 11 and the lower fixing strips 15 are used to strengthen the strength of the bottom plate 10. At the same time, the upper fixing strips 11 also have a limiting effect between the lower surface of the cover plate 20 and the upper surface of the bottom plate 10, preventing the cover plate 20 from pressing down on the bottom plate 10 excessively and damaging the products inside the spraying fixture.

[0049] Please refer to Figure 1 , Figure 2 and Figure 14 , the spraying fixture further includes an insert 30. The insert 30 passes through the cover plate 20 and is inserted into the bottom plate 10. Wherein, the insert 30 includes an insertion post 31 and a fixing plate 32 connected to the end of the insertion post 31. A corresponding insertion seat 12 for the insertion post 31 is provided on the upper surface of the bottom plate 10, and a fixing hole 23 for accommodating the fixing plate 32 is formed through the cover plate 20.

[0050] When the utility model is in use, first place the product on the bottom plate 10, then cover the cover plate 20 on the bottom plate 10, and then insert the insertion post 31 of the insert 30 into the insertion seat 12 of the bottom plate 10. At the same time, the fixing plate 32 is accommodated in the fixing hole 23. Finally, the spraying material is sprayed on the surface of the product at the gap between the fixing plate 32 and the cover plate 20.

[0051] The spraying fixture provided by the utility model is not only convenient for disassembly and assembly, but also can avoid damaging the buckle structure during the disassembly and assembly process.

[0052] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
