A sliding door drive rack adjusting and fixing device

Abstract

The invention discloses an adjusting and fixing device for a transmission gear rack of a sliding door. The adjusting and fixing device comprises a C-type mounting steel plate and the gear rack. A plurality of movable sliding blocks are arranged in the C-type mounting steel plate, a plurality of mounting clamping strips are arranged outside an opening of the C-type mounting steel plate, and the two ends of each mounting clamping strip are bent to extend to the top end and the bottom end of the C-type mounting steel plate respectively. Anti-falling cushion blocks are arranged outside the mounting clamping strips, fixed bolts are arranged on the gear rack, and the fixed bolts sequentially penetrate through the gear rack, the anti-falling cushion blocks, the mounting clamping strips and the movable sliding blocks to be connected with threaded holes. In this way, according to the adjusting and fixing device for the transmission gear rack of the sliding door, the movable sliding blocks, the mounting clamping strips, the anti-falling cushion blocks and the gear rack are connected in series and fixed together through the fixed bolts, the movable sliding blocks can be movably adjusted conveniently, the stationarity of the tightened fixed bolts is good, mounting convenience and work efficiency are improved, the gear rack can be spliced conveniently, and construction and maintenance cost is lowered.

Description

technical field [0001] The invention relates to the field of translation doors, in particular to an adjusting and fixing device for a transmission rack of a translation door. Background technique [0002] The traditional electric gates at the entrance and exit of the perimeter are split or electric telescopic gates, which have high requirements on the ground and tend to be gradually eliminated. However, the translational cantilever gate products have been well received by users for their superior ground adaptability and integrity. unanimous approval. The core part of the translational cantilever gate is the gate bottom beam, which provides a strong rigid foundation for the entire gate body, so that the gate can be suspended in the air, and at the same time constitutes a pulley track, so that the gate moves on the fixed pulley to reach the opening and closing cycle. The purpose of border entrance and exit. [0003] The motor-driven translation door is generally driven by a ...

AI Technical Summary

Problems solved by technology

Because the fixing bolts of the rack are not adjustable, when it is applied to the cantilevered sliding door, there is a problem of interference of the pulley device in the inner space of the bottom beam of the sliding door, and the ribbed bottom beam is self-molded due to the spacing of the ribs. The number cannot be matched with the mounting bolts of the rack, which leads to the defect that the rack transmission mode cannot be used
