Sunshade buffers for vehicles and ships

Abstract

The invention belongs to an abat vent buffer for vehicles and vessels. The abat vent buffer is provided with a transmission damping jacket, wherein a protruding clamp gear is arranged at one end of the transmission damping jacket, and a fixed shaft of a damping shaft penetrates through a through hole formed in the protruding clamp gear of the transmission damping jacket to be fixedly connected with the side surface of a shutter base frame in a matched mode. A damping inner hole is formed at one end of the transmission damping jacket, damping grooves are evenly distributed on the wall of the damping inner hole, a threaded shaft of the damping shaft is in threaded connection with the a damping shaft sleeve, and protruding strips used for generating damping force are evenly distributed on an outer cylinder of the damping shaft sleeve. The damping shaft and the damping shaft sleeve are arranged in the damping inner hole of the transmission damping jacket, the damping shaft sleeve and the damping inner hole are in fit connection at intervals, high-viscosity oil for assisting damping is filled in the damping inner hole, and the end surface of the damping inner hole is pressed by an end cover for seal. The abat vent buffer for vehicles and vessels has the effects of good stability, long service life, strong universality, muting and shock absorption, and thorough unreeling buffer, and can be applied to abat vents of various small, medium and large-sized vehicles, vessels and special mechanical vehicles as well as civil shutters.

Description

technical field [0001] The invention belongs to a sunshade buffer, in particular to a buffer suitable for sunshade roller blinds of various vehicles, ships and special mechanical vehicles. Background technique [0002] Existing vehicle sunshade roller blind mainly is made up of roller shade seat frame, roller shade rod, roller blind, coil spring, positioning stop switch. Such as Chinese Patent Publication No. CN2122770U, discloses a vehicle sunshade roller blind that can be positioned and controlled, consisting of an axle rod, two axle sleeves, a strut, a coil spring, two side covers, a push rod, and a cover sheet; The right shaft sleeve and the right side cover are provided with a convex and concave locking teeth, which are locked in the forward direction and slide in the reverse direction. When the roller blind is pulled down during use, the convex teeth of the right bushing will slide in reverse in the concave teeth of the right cover. When positioning, you only need to ...

AI Technical Summary

Problems solved by technology

Since the roller blind does not have a mechanism to limit the recovery speed of the coil spring, when the roller blind is quickly retracted to the final position, the speed of the lower cross bar of the roller blind from the fastest to zero will have a great impact on the seat frame of the roller blind, and produce shock vibration and impact noise , not only easily lead to sunshade failure, but also reduce the life of the sunshade roller blind, and also cause safety hazards to the user who may be impacted by the high-speed rebound of the roller blind
