Open type lock catch for automobile sliding door clamp

Abstract

The invention discloses an open type lock catch for an automobile sliding door clamp. The open type lock catch comprises a rotating handle (1), a linkage rotating shaft (2), a lock catch body (5), a first supporting ring (6), a second supporting ring (7) and a plurality of supporting connecting rods (8), one end of the rotating handle is connected with one end of the linkage rotating shaft, the lock catch body is connected to the other end of the linkage rotating shaft, the middles of the first supporting ring and the second supporting ring are provided with a through hole, the linkage rotating shaft penetrates the first supporting ring and the second supporting ring through the through hole, and the supporting connecting rods are respectively connected between the first supporting ring and the second supporting ring to form a rotating shaft fixed base with which the linkage rotating shaft is sleeved. The rotating shaft exposed open type structure is adopted, the possibility that the linkage rotating shaft is clamped can be greatly reduced by reducing the contact area, automobile sliding door clamp installation and operation are ensured, the production efficiency is improved, and the repair cost is reduced.

Description

Technical field [0001] The invention relates to an automobile tooling fixture, in particular to an open lock catch for an automobile sliding door fixture. Background technique [0002] In the process of painting the car body, in order to prevent the paint from being scratched or leaving a mark and cannot be touched, it needs to be supported and fixed by fixtures. At present, most of the large clamp locks used to fix the sliding door adopt a closed structure, please refer to the attached figure 1 The closed structure includes a rotating handle 1, a linkage shaft 2, a fixed sleeve 3, and a lock plate 4. When in use, the rotating handle 1 rotates and drives the lock plate 4 through the linkage shaft 2 to rotate the lock plate 4 as a sheet structure and is linked with The rotating shaft 2 is welded into one body, and the linkage rotating shaft 2 rotates inside the fixed sleeve 3 by the support of the fixed sleeve 3, thereby controlling the opening and closing of the lock plate 4.

AI Technical Summary

Problems solved by technology

[0003] Since the paint may enter the fixed sleeve 3 through the gap between the linkage shaft 2 and the fixed sleeve 3 during spraying, the linkage shaft 2 is stuck and unable to rotate, which affects the installation and operation of the sliding door fixture, affects the output, and the subsequent repair costs are high.

Moreover, the welding point between the locking piece 4 and the linkage shaft 2 is easy to crack or even break after frequent and long-term use, which affects the locking of the locking piece 4
