DETAILED DESCRIPTION

[0020] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] Reference Figure 1 , Figure 2 and Figure 3As shown, the embodiment of the present application discloses an electrophoretic rack for pre-treatment of painting, including: a main body 1; a plurality of positioning pins 11, which are arranged on the main body 1 and are used to position the vehicle body 7; a plurality of support blocks 12, which are arranged on the main body 1 and are used to place the vehicle body 7; at least two sets of locking components, which are symmetrically arranged on the main body 1; wherein the locking components include: a locking rod 21, which is hingedly mounted on the main body 1; an abutment component 22, which is arranged on the locking rod 21 and is used to abut the vehicle body 7; an elastic component 23, one end of which is connected to the locking rod 21 and the other end is connected to the main body 1, which is used to provide the abutment component 22 with an inner movement tendency close to the vehicle body 7.

[0022] When in use, the positioning pin 11 is inserted into the vehicle body 7 to complete the positioning of the vehicle body 7 , and the support block 12 is used to abut against the bottom surface of the vehicle body 7 , so that the vehicle body 7 is placed on the main body 1 .

[0023] It can be understood that the support block 12 is provided with stepped surfaces of different heights for supporting vehicle bodies 7 of different models.

[0024] In the utility model, a locking assembly is provided, and the elastic component 23 drives two symmetrically arranged locking rods 21 to drive the abutment component 22 to abut the inner surface of the vehicle body 7, so as to lock the vehicle body 7 on the main body 1; by using the utility model, the vehicle body 7 can be effectively fixed on the hanger to prevent the vehicle body 7 from floating during the electrophoresis operation; and by abutting the inner surface of the vehicle body 7 with the locking assembly, the area of ​​the vehicle body 7 surface that is shielded can be effectively reduced, thereby improving the efficiency of the electrophoresis operation.

[0025] In this embodiment, the elastic component 23 is a spring, one end of the spring is connected to the locking rod 21, and the other end is connected to the main body 1. The locking rod 21 and the main body 1 are elastically connected by the elastic component 23, which can meet the locking work of vehicle bodies 7 of different widths, is suitable for electrophoresis operations of different vehicle models, and can improve the scope of application.
