Detachable coating hanger buckle

Abstract

The invention relates to the field of coating hangers and discloses a detachable coating hanger buckle which comprises two equal trapezoidal mounting plates, each of which comprises a fixed portion, an inserting portion and a connecting portion, the inserting portions and the connecting portions are arranged at the two ends of the fixed portions respectively; the inserting portions and the connecting portions are bent towards the same side; connecting groove holes are formed in the connecting portions respectively; and the side walls of the inserting portions are in point contact with the inner walls of the connecting groove holes respectively. The detachable coating hanger buckle has the following advantages and effects that: detachable connection of a suspender and a hanging rod is realized through mutual insertion of the inserting portions of the two mounting plates and the connecting groove holes, and meanwhile, the contact area of the two mounting plates is reduced through point contact of the side walls of the inserting portions and the inner walls of the connecting groove holes, so that the stress at the contact part of the two mounting plates is improved while the two mounting plates are prevented from being adhered too closely, electrophoresis paint films attached to the side edges of the inserting portions and the connecting groove holes are scraped, and the conductive effect of the suspender and the hanging rod is ensured; and the two mounting plates are equal in shape and size, so that the manufacturing cost of the mounting plates is reduced, and the manufacturing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of painting hangers, in particular to a detachable paint hanger buckle. Background technique [0002] Electrophoretic coating is a special coating film forming method, which is divided into anodic electrophoretic coating and cathodic electrophoretic coating. It is to immerse the coated object with conductivity in the electrophoretic coating tank solution filled with water and have a relatively low concentration as the anode (or cathode), and set up the corresponding cathode (or anode) in the tank. A coating method in which a uniform, water-soluble coating film is deposited or deposited on the surface of the object to be coated after a certain period of time through direct current. According to the polarity of the object to be coated and the type of electrophoretic coating, the electrophoretic coating method can be divided into two types: anodic electrophoretic coating method, the object to be coated is an a...

Problems solved by technology

[0003] The existing painting hanger is shown in the figure, including a suspender and a hanging rod. The insertion groove is welded on the suspender, and a plurality of hooks and a plugging block located in the middle of the hanging rod are welded on the hanging rod. The plugging block is inserted The detachable connection between the suspender and the hanging rod is realized in the socket slot, which is used to replace the hanging rod for different types of parts to be painted. For the painting hanger, the electrophoretic paint will adhere to the surface of the hanger when it is in use. In order to ensure The conductivity of the hanger requires sandblasting on the spreader to remove the electrophoretic paint attached to the surface of the spreader, but there are defects in this type of connection, because the electrophoretic paint will adhere to the inner wall of the socket when spraying, due to the The block and the socket are in contact with each other through the surface. After repeated sandblasting, the thickness of the socket and the socket becomes thinner, and the gap between the socket and the end face of the socket gradually increases so that the hanger can only pass through the side. The contact is conductive, and the narrow sides of the socket slot cannot guarantee the sandblasting effect, which makes the conductivity between the hanger and the hanger worse, which affects the quality of the coating. At the same time, the gap gradually increases, making the electrophoretic paint attached to the gap thicker. , resulting in the adhesion of the socket slot and the socket block, making it difficult to separate the socket socket from the socket block
