Cranked arm linkage secret door

Abstract

The invention discloses a crank arm connecting rod blank door. The crank arm connecting rod blank door comprises guide rails (1), connecting rod assemblies (3), blank door supporting rods (5) and a blank door body. Sliding grooves shaped like a Chinese character 'hui' are formed inside the guide rails (1), screw holes are formed in the bottoms of the sliding grooves, and the guide rails (1) are fixedly connected with the top and the bottom of a frame body through wood screws along frame edges. One ends of the connecting rod assemblies (3) are connected with the guide rails (1) in a rotating mode through moving sliding blocks (2) arranged in the sliding grooves, and the other ends of the connecting rod assemblies (3) are connected with the blank door supporting rods (5) in a rotating mode through fixing rotary knobs (4) to form blank door connecting pieces. The blank door supporting rods (5) are provided with screw holes, the blank door body is provided with edge grooves, screw holes corresponding to the blank door supporting rods (5) are formed in the inner side edge opening positions of the edge grooves, and the blank door supporting rods (5) are fixed through wood screws along the upper inner side edge and the lower inner side edge of the blank door body to form an integrated structure. According to the crank arm connecting rod blank door, the upper blank door connecting piece and the lower blank door connecting piece are fixed to the upper end and the lower end of the wood blank door body in a matched mode, guarantees are provided for overall force bearing of the blank door, components are installed in place at one time, and the repair rate is low.

Description

technical field [0001] The invention relates to a curved arm connecting rod secret door. Background technique [0002] At present, for the installation of wooden side-hung secret doors on walls in architectural decoration projects, installation hardware such as hinges, pipe hinges, and cross hinges are mostly used. These hardwares have different installation disadvantages, which affect the overall installation effect and use function. [0003] Conventional secret door installation hardware installation methods have the following disadvantages: [0004] 1. Installing the hidden door with hinges can solve the load-bearing problem of the hidden door, but the hinge shaft is exposed, which affects the aesthetics of the overall installation effect. [0005] 2. Installing the secret door on the pipe hinge can control the overall appearance effect very well, but the force and load bearing capacity of the pipe hinge is limited, and it is difficult to meet the load-bearing problem of...

AI Technical Summary

Problems solved by technology

[0004] 1. Hinge installation of hidden doors can well solve the load-bearing problem of hidden doors, but the hinge shaft is exposed, which affects the aesthetics of the overall installation effect

[0005] 2. The hidden door installed on the pipe hinge can well control the overall appearance effect, but the force and load bearing of the pipe hinge is limited, and it is difficult to meet the load-bearing problem of the oversized and overweight secret door

[0006] 3. The cross-hinge installation of the secret door has limited overall force and load bearing for the secret door. At the same time, the internal structure and process requirements of the secret door are relatively complicated, which will easily lead to cracking of the door leaf edge and high repair rate
