Description

Technical Field

[0001] The utility model belongs to the technical field of packaging tools, in particular to a special type pressing device. Background Art

[0002] As the heart of new energy vehicles, power batteries require specific packaging equipment during transportation. As an important component of packaging equipment, the latch-type quick clamp plays a vital role in the entire transportation safety process of power batteries. At present, power battery packaging equipment is designed according to different types of battery packs. The traditional quick clamp takes up a lot of space and has a relatively small clamping force. To some extent, it increases the manufacturing cost of packaging equipment and the transportation of finished products, as well as increases safety risks during transportation.

[0003] After searching, the Chinese patent application (announcement) number is 202220773763.X. A latch-type quick clamp for use in the field of power battery recycling logistics packaging equipment is proposed, including a shell, a quick clamp mounting plate, a rear side plate, a linear bearing, a sliding shaft, a latch plate, a pressure plate, a polyurethane plate, a first spring, a second spring, a ball head locking pin, a flat washer, a first screw, a first nut, a thin nut, and a second screw. The shell is fixedly mounted on the quick clamp mounting plate by the first screw and the flat washer, and the rear side plate is fixedly arranged on the right part of the shell, and other technical features. When the latch-type quick clamp for use in the field of power battery recycling logistics packaging equipment is used, the latch-type quick clamp is in the starting state, and the staff presses the pressure plate downward with their hands to move downward, so that the latch plate enters the sliding shaft position under the action of the first spring, so that the sliding shaft stops moving, and the second screw is inserted into the through hole at the top of the shell to prevent shaking, so that the polyurethane plate presses the power battery pack tightly, fixes it on the packaging equipment, and enters the clamping state, and other technical effects;

[0004] The latch plate in the patent is "L" shaped, and during installation, it is necessary to form a limit rib inside the housing for the horizontal sliding of the latch plate. The limit rib is difficult to form inside the housing, and is not easy to process and has high cost.

[0005] The latch plate can only be installed and removed inside the housing before the rear side plate is closed, which is not conducive to the maintenance and replacement of the latch plate and other components in the later stage;

[0006] The through hole on the shell for cooperating with the positioning screw is set individually, and the clamping position cannot be adjusted according to the actual clamping position and needs, resulting in limited use.

[0007] In order to solve the above problems, a special pressing device is proposed in the present application. Utility Model Content
