Locking structure

Abstract

The invention discloses a locking structure. The locking structure comprises a transmission shaft and transmission gears. The transmission gears are arranged at the two ends of the transmission shaft. Two sets of guiding rails are arranged along a joint part of an openable component and a fixing component and comprise transmission racks and the transmission gears engaged with the transmission racks, and a plurality of sets of tightening mechanisms are arranged on the guiding rails at intervals. Each tightening mechanism is composed of a frapping piece, sliding blocks, a locking shaft and a back locking pin, wherein the frapping piece is located on the side of the joint part of the openable component and the fixing component, the front part of the frapping piece is vertically and fixedly connected with the locking shaft in the axial direction, and a lock hole used for enabling the back lock pin to vertically insert in is formed in the rear part of the frapping piece; and the two sliding blocks with inclined faces are fixedly arranged between the locking shaft and the back lock pin and on the two surfaces of the corresponding guide rail. The locking structure is stable in structure and high in reliability and sealing performance, and manual and power-driven back locking and compressing can be achieved. The locking structure can be arranged on a relatively large cabin door plane in a balancing manner and can achieve unlocking and locking linkage, opening and closing of a cabin door are more convenient, locking and sealing are balanced, and the sealing effect is more excellent.

Description

technical field [0001] The invention belongs to the technical field of mechanical design and manufacture, in particular to the design and manufacture of a locking mechanism for a door, and in particular to a locking and sealing structure for a security life-saving device. Background technique [0002] The doors of the existing rescue cabins generally have the problems of complex structure of the opening and closing mechanism, poor sealing and heat insulation effects, water pressure and air tightness cannot meet the requirements, and manual and electric simultaneous closing and locking cannot be realized. [0003] Especially for larger hatches, because of the large area, it is impossible to achieve the compression and sealing of the overall hatch only by relying on locks and hinges to fix and seal when sealing. Although some problems can be solved by adding locks and strengthening methods, but for larger With a large plane door, the locking force of each lock is different, th...

Problems solved by technology

[0002] The doors of existing rescue cabins generally have the problems of complex structure of opening and closing mechanism, poor sealing and heat insulation effects, water pressure and air tightness cannot meet the requirements, and manual and electric simultaneous closing and locking cannot be realized.

[0003] Especially for larger hatches, because of the large area, it is impossible to achieve the compression and sealing of the overall hatch only by relying on locks and hinges to fix and seal when sealing. Although some problems can be solved by adding locks and strengthening methods, but for larger The large plane of the hatch, the locking force of each lock is different, the locking effect cannot meet the requirements, and the practical application is also very inconvenient
