Abstract
The utility model relates to the technical field of automotive accessories, in particular to a dust cover of a piston rod. The dust cover of the piston rod comprises a cover body, wherein the cover body comprises an end cover plate arranged at the upper end of the cover body, a through hole enabling the end cover plate to be matched and connected with the piston rod in a sleeved mode conveniently is formed in the middle of the end cover plate, an installation plate is arranged at the lower end of the end cover plate, at least three installation positions are formed in the outer edge of the installation plate, and a magnet is arranged on the end face of each installation position. According to the dust cover of the piston rod, the installation positions are formed in the outer edge of the installation plate, the magnet is arranged on the end face of each installation position, a positioning hole is formed in the inner wall of the end cover plate in a concave mode, therefore, the dust cover can be tightly connected with the piston rod conveniently through the cooperation and connection between the installation positions and an outer cylinder, attraction of the magnets and the cooperation and connection between the positioning hole and the piston rod, and installation is simple and convenient. Therefore, dust can be prevented from entering the piston rod, and normal movement of the piston rod and a piston is guaranteed.
Description
Technical field
The utility model relates to the vehicle accessory technical field, relates in particular to a kind of piston rod dust-proof cover.
Background technique
Along with automotive industry, the particularly fast development of car industry, vibration damper as the important accessory of automobile, also obtained development rapidly, automobile absorber is a kind of damping member, it is one of important component of automobile suspension system, smoothness, travelling comfort, Security, steering operation and passing ability to Vehicle Driving Cycle play conclusive effect, the working principle of vibration damper is that piston lever of reducer is in the process of motion, shock absorber fluid constantly circulates by the damping hole on piston and foot valve seat, thereby is kinetic transformation that heat energy is dispersed in air.But in prior art, the piston rod of vibration damper is in movement process, can be subject to the impact of dust, and causes the slow of piston rod and piston movement or lost efficacy, therefore need to carry out proofing dust and protecting to piston rod.
Summary of the invention
The purpose of this utility model is to provide a kind of piston rod dust-proof cover, and it has can prevent dust intrusion piston rod, guarantees the characteristics of the proper motion of piston rod and piston.
For achieving the above object, the utility model adopts following technical proposals:
A kind of piston rod dust-proof cover, comprise cover body, and cover body comprises the end casing of being located at upper end, the end casing middle part offers the through hole of being convenient to coordinate with piston rod socket, the end casing lower end is provided with mounting plate, and the mounting plate outer rim offers at least three installation positions, and the end face of installation position is provided with magnet.
Wherein, described installation position comprises vertical mounting groove of being located at the mounting plate outer rim, and vertically the mounting groove bottom offers semicircular horizontal mounting groove.
Wherein, described end casing inwall is concaved with at least three positioning holes, and positioning hole comprises the blind hole that is opened in the end casing inwall and is convexly set in the boss of end casing top and corresponding blind hole.
Wherein, described mounting plate outer rim offers six installation positions.
after adopting said structure, the beneficial effects of the utility model: the utility model comprises cover body, cover body comprises the end casing of being located at upper end, the end casing middle part offers the through hole of being convenient to coordinate with piston rod socket, the end casing lower end is provided with mounting plate, the mounting plate outer rim offers at least three installation positions, the end face of installation position is provided with magnet, the utility model is by offering installation position in the mounting plate outer rim, the end face of installation position is provided with magnet, and at the end casing inwall, be concaved with positioning hole, be connected by installation position and urceolus like this, being connected of the absorption of magnet and positioning hole and piston, can conveniently with piston rod, closely be connected, and install simple, convenient, can prevent like this dust intrusion piston rod, guarantee the proper motion of piston rod and piston.
