Description

Technical Field

[0001] The utility model relates to the technical field of hangers, in particular to a hanger for spraying rectangular tubes. Background Art

[0002] Electrostatic spraying is a spraying method that uses a high-voltage electrostatic field to make negatively charged paint particles move in a directional direction opposite to the electric field, and adsorb the paint particles on the surface of the workpiece. Electrostatic spraying equipment consists of a spray gun, a spray cup, and an electrostatic spraying high-voltage power supply. Electrostatic spraying requires that the conductivity of the hanger is good to ensure the amount of paint attached during electrostatic spraying. At the same time, the hanger structure is required to be suitable for placing the parts to be hung and enable them to be fully sprayed in place.

[0003] For workpieces such as square tubes and rectangular tubes, the spray hanger is a single hook that hangs the inner hole on the top for spraying. After hanging, the hanger is easy to shake, there are hanger points on the appearance after spraying, and the conductivity will become poor or even non-conductive after the second spraying. Therefore, most hangers and hooks now need to be replaced after spraying twice. After spraying twice, the conductivity of the hanger becomes poor or even non-conductive, and the hanger and hook need to be replaced; the hook is easy to fall off when hanging with a single hook, and the hook is easy to be taken out when the workpiece is removed after spraying; the workload of replacing the hanger and hook is large, the work efficiency is low, and it consumes labor. For this reason, the utility model provides a hanger for spraying rectangular tubes to improve the spraying efficiency and yield rate, realize multiple spraying without hanging points, ensure beautiful appearance, no need to replace the hanger and hook for multiple spraying, and the hook can be quickly replaced, which is convenient and simple, reduces worker consumption and reduces energy costs.

[0019] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0020] Figure 1-5 A rectangular tube spray hanger is shown, comprising a hook 1 and an insert 2, the insert 2 being suitable for being placed in the inner cavity of a rectangular tube 4, the insert 2 comprising two S-shaped arms 201, a U-shaped tube 202, a support frame 203 and a transverse tube 204, the two ends of the S-shaped arms 201 being parallel to each other and suitable for overlapping the inner wall of the rectangular tube, the two ends of the U-shaped tube 202 being respectively welded to the middle of the two S-shaped arms 201 and being flush with each other, the middle parts being welded with a transverse tube 204, the ends of the two S-shaped arms 201 close to the turning point 20201 of the U-shaped tube 202 being welded with a support frame 203, the other ends of the support frame 203 being welded to the two ends of the U-shaped tube and close to the turning point 20201. By using the insert, it is easy to take and not easy to fall out. The inner wall of the workpiece (having a structure similar to the rectangular tube 4) will not occupy powder during the spraying process, and the conductive performance of the hanger will not be reduced after spraying, so the hanger can be sprayed multiple times without replacement; the embedded part is located at the center of the workpiece hole and does not contact the outer wall of the workpiece. Therefore, the original hanging part of the outer wall of the workpiece does not need to be repainted or removed for secondary treatment of excess paint, thereby improving the spraying efficiency and yield rate, realizing multiple spraying without replacing the hanger and hook, and the hook can be quickly replaced, which is convenient and simple, reduces worker consumption and reduces energy costs.

[0021] In order to make the inner part 2 more suitable for being placed in the inner cavity of the rectangular tube, as Figure 3 , one end of the two S-shaped arms 201 is hinged at the middle thereof, and the end is connected to the middle of the S-shaped arm 201 by a spring 3, and the end is far away from the turning point 20201. By setting one end of the S-shaped arm 201 to be hinged and using the spring to assist, the entire inlay 2 can be adaptively attached to the inner wall of the rectangular tube 4, so that the rectangular tube 4 can be hung more stably.

[0022] When it is necessary to place the insert 2 deeper into the inner cavity at both ends of the rectangular tube, Figure 4 , a retractable nested structure is set between the two ends of the U-shaped tube 202 and the turning part 20201. By pulling the above-mentioned nested structure, the position of the embedded part 2 entering the inner cavity of the two ends of the rectangular tube 4 can be adjusted, which is also conducive to hanging the rectangular tube 4.

[0023] Of course, the hook 1 and the embedded part 2 can be set to be separate or welded together, such as Figure 1, the U-shaped tube 202 is vertically welded to the hook 1 at the turning point 20201; Figure 5 , hook 1 is hooked at turning point 20201.

[0024] Working principle of this utility model:

[0025] The hanger utilizes a structure in which a hook 1 and an embedded part 2 cooperate with each other, and the workpiece (i.e. Figure 1 4) After the rectangular tube in the middle is hung, the embedded parts are placed in it. After spraying and curing, there will be no hook scars or hook collisions on the workpiece. No powder will enter during the spraying process, ensuring that the hanger has good conductivity. After the embedded parts are hung in the inner cavity of the rectangular tube, they will not be unhooked 100% and have good stability, reducing the handling of the hanger.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
