DETAILED DESCRIPTION
[0031] The following is combined with Figure 2-4 This application is described in further detail.
[0032] The embodiment of the present application discloses a spray paint hanger for a close-ring spring, which is mainly suitable for spray painting of a close-ring spring. Figure 2 The spray paint rack includes a frame 3, a plurality of hooks 4 and a rotary joint 5. The frame 3 includes a main rod 31, an upper crossbar 32 and a lower crossbar 33. The main rod 31 is arranged along the vertical direction, the upper crossbar 32 and the lower crossbar 33 are arranged parallel and opposite to each other in the horizontal direction, and the upper crossbar 32 and the lower crossbar 33 are welded to the two ends of the main rod 31. The hooks 4 are arranged at intervals along the length direction of the upper crossbar 32 and the lower crossbar 33, and the hooks 4 are located on the side facing the upper crossbar 32 and the lower crossbar 33, and the hooks 4 are arranged in pairs up and down.
[0033] Reference Figure 3 and Figure 4 The number of the swivel joints 5 is the same as the number of the hooks 4. The swivel joints 5 are clamped on the hooks 4. The outer side of the swivel joints 5 is provided with a thread groove 6. The thread groove 6 is located at one end of the swivel joints 5. The thread groove 6 and the inner wall of the seal ring spring when it is not stretched are threadedly matched with each other. The swivel joint 5 is cylindrical, and the swivel joint 5 can be quickly threadedly connected to one end of the seal ring spring by rotating, so as to achieve the threaded fixation of the swivel joint 5 and the end of the seal ring spring; the opposite sides of the side wall of the swivel joint 5 are provided with hanging holes 7. The hanging holes 7 are located at a position away from the thread groove 6. The hooks 4 are clamped on the hanging holes 7 to achieve the quick hanging cooperation between the swivel joint 5 and the hooks 4.
[0034] When the seal ring spring is installed on the hanger, the swivel joint 5 at one end of the seal ring spring is clamped with the hook 4 of the upper cross bar 32, and then the seal ring spring is stretched to expand the circles of the seal ring spring, and the swivel joint 5 at the other end of the seal ring spring is clamped with the hook 4 of the lower cross bar 33, so as to achieve indirect fixation of the two ends of the seal ring spring and the hook 4. Therefore, the hook 4 does not directly contact the seal ring spring, and the swivel joint 5 is located inside the end of the seal ring spring, so it will not affect the painting of the seal ring spring.
[0035] The hook 4 is formed by bending the rod material, and includes a mounting portion 41, an elastic portion 42 and a clamping portion 43. The elastic portion 42 and the clamping portion 43 are both provided with two pieces, and the two elastic portions 42 are arranged at intervals. The clamping portion 43 is fixed to one end of the elastic portion 42, and the clamping portion 43 is located on the side of the two elastic portions 42 that are away from each other. The angle between the clamping portion 43 and the elastic portion 42 is an acute angle, and the clamping portion 43 and the elastic portion 42 form a hook structure that cooperates with the hook hole 7. The mounting portion 41 is fixed to one end of the two elastic portions 42 away from the clamping portion 43, and the mounting portion 41 is used to connect the two elastic portions 42. The mounting portion 41 and the end of the elastic portion 42 close to the mounting portion 41 are detachably connected to the upper cross bar 32 or the lower cross bar 33, so as to facilitate the stable installation of the hook 4.
[0036] In some embodiments, the mounting portion 41 includes a U-shaped frame 411 and two flat rods 412, wherein one end of the flat rod 412 is fixed to the end of the elastic portion 42 away from the clamping portion 43, and the other flat rod 412 is connected to the end of the other elastic portion 42 away from the clamping portion 43. The two ends of the opening of the U-shaped frame 411 are connected to the ends of the two flat rods 412 away from the elastic portion 42. The mounting portion 41 and the elastic portion 42 are surrounded to form a clamp, and the upper cross bar 32 or the lower cross bar 33 is located in the clamp. The U-shaped frame 411 and the elastic portion 42 are respectively located on opposite sides of the upper cross bar 32 or the lower cross bar 33, so that the hook 4 can hook the upper cross bar 32 or the lower cross bar 33, and the hook 4 is then locked to the frame 3 by the bolt and nut assembly 8 to achieve a detachable connection between the hook 4 and the frame 3.
[0037] In some embodiments, the upper crossbar 32 and the lower crossbar 33 are provided with adjustment holes 9 along their length direction, and the bolts in the bolt and nut assembly 8 pass through the U-shaped frame 411, the adjustment holes 9 and the interval between the two elastic parts 42, and then are locked by nuts. Therefore, according to the installation position of the adjustment hook 4, the position adjustment of the hook 4 in the length direction of the upper crossbar 32 and the lower crossbar 33 is achieved, and the interval between the close ring springs installed on the frame 3 can be adjusted. Among them, a washer 10 is sleeved at the position of the bolt close to the nut, and the washer 10 fits with the U-shaped frame 411 to ensure that the bolt and nut assembly 8 is stably pressed on the hook 4.
[0038] The implementation principle of a paint hanger for a sealed ring spring in an embodiment of the present application is as follows: when in use, the swivel joint 5 is removed from the hook 4, and the swivel joint 5 is threadedly connected to the inside of the two ends of the sealed ring spring. At this time, one end of the swivel joint 5 still extends out of the sealed ring spring, and then the two elastic parts 42 of the hook 4 in the upper cross bar 32 are pressed, so that the two elastic parts 42 and the clamping part 43 are close to each other and can extend into the swivel joint 5. When the clamping part 43 is horizontally opposite to the hanging hole 7, the pressure on the elastic part 42 is cancelled, and the elastic part 42 and the clamping part 43 are reset. At this time, the clamping part 43 is clamped into the hanging hole 7 to realize the connection between the swivel joint 5 and the hook 4. Then, the seal ring spring is stretched so that each coil of the seal ring spring is expanded, and the swivel joint 5 at the other end of the seal ring spring is hung on the hook 4 of the lower cross bar 33, so that the two ends of the seal ring spring and the hook 4 are indirectly fixed. Therefore, the hook 4 is not directly in contact with the seal ring spring, and the swivel joint 5 is located inside the end of the seal ring spring. Therefore, it will not affect the painting of the seal ring spring, thereby achieving the effect of reducing the hanging point generated during painting, and facilitating the connection between the seal ring spring and the hanger.
[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
