Embodiment Construction

[0016] Such as figure 1 , 2 , 3, 4 and 5, an isolating device for a plug-in door platform compensator includes a lock cylinder 1, a spacer 2, an isolating stopper 3, a connecting rod 4 and an isolating bolt assembly, and the isolating bolt assembly includes an isolating bolt assembly Shaft 5, connecting plate 6, locking tongue 7 and elastic member 8, connecting plate 6 and locking tongue 7 are installed on the isolation shaft 5 to rotate and the positions of connecting plate 6 and locking tongue 7 are relatively fixed, and elastic member 8 drives connecting plate 6 and The dead bolt 7 rotates and resets, and the elastic member 8 is a torsion spring.

[0017] The spacer 2 is installed on the lock cylinder 1 and fixed relative to the lock cylinder 1 .

[0018] The spacer 2 and the connecting plate 6 are connected by a connecting rod 4, and the spacer 2, the connecting rod 4 and the connecting plate 6 form a four-bar linkage structure.

[0019] The spacer 2 has an upper limit ...

Abstract

The invention relates to an isolation device of a platform compensator for a sliding plug door. The isolation device comprises a lock cylinder, an isolation sheet, an isolation stopping block, a connection rod and an isolation spring bolt assembly. An elastic piece drives a connection plate and a spring bolt to reset in a rotating mode. The isolation sheet is installed on the lock cylinder and fixed relative to the lock cylinder. The isolation sheet and the connection plate are connected through the connection rod. When the isolation device is in the initial state, the isolation sheet rotates clockwise to cross the dead motion spot between the isolation sheet and the connection rod; and when the isolation device is in the isolated state, the lock cylinder drives the isolation sheet to move anticlockwise to an upper limiting portion to make contact with the isolation stopping block, and the spring bolt is in a locked state. The isolation device has the beneficial effects that when the isolation device is in the initial state, as the isolation sheet rotates clockwise to cross the dead motion spot between the isolation sheet and the connection rod, the whole isolation device bears a downward pre-tightening force under the joint action of a lower limiting portion of the isolation sheet and the elastic piece, the effect that components of the isolation device are free of bounce and disengagement when a vehicle body is in a vibrating state is ensured, and reliability is improved.

Description

technical field [0001] The invention relates to an isolating device for a platform compensator of a sliding door. Background technique [0002] At present, the platform compensator of the sliding door system is designed and manufactured by foreign manufacturers. Wherein the isolating device is positioned by the wavelet screw on the isolating limiting groove of the isolating sheet. This kind of structure has the hidden danger of loosening or shaking when the car body vibrates. Once the positioning effect of the wavelet screw on the spacer fails, the spacer will fail. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an isolating device for a platform compensator of a sliding door to improve reliability. [0004] The technical solution adopted by the present invention to solve the technical problem is: an isolating device for a plug-in door platform compensator, including a lock cylinder, a spacer, an isolating st...
