Abstract

The invention relates to a dust cover for a lock combined with a brake of bicycle and electric bicycle. The structure of the utility model is that: a rotor shaft hole is arranged at the lower end of the dust cover and connected with a left upright lug and a right upright lug on one side of the lock, a hollow concave wheel, a hollow convex wheel and a spring are sequentially disposed in the rotor shaft, a fixing pin is passed through the hollow sites of the hollow concave wheel, the hollow convex wheel and the spring, the hollow concave wheel is alternately engaged with the hollow convex wheel, the tail part of the hollow concave wheel has a non-round structure that is mated with the non-round structure of the left upright lug, and the tail part of the hollow convex wheel also has a non-round structure. The utility model solves the problems of the existing dust cover, including poor sealability and operating performance, large stress, and damage liability. The utility model has the advantages of good sealability, easy operation, and 180 DEG turning range; and is especially suitable for mated use with various brake locks. It can remarkably prolong the service life of the brake locks, and bring convenience to customers.

Description

The car lock cover of dust of stopping
Technical field
The utility model relates to a kind of lock dust keeper, particularly a kind of brake lock cover of dust of stopping and combining with bicycle, electric bicycle.
Background technology
Before the present utility model, brake lock is the function that has increased lock on the basis of various brakes, thereby vehicle-mounted position is lower, the in use as easy as rolling off a log mud dust of being infected with, thus can influence lock car and brake function.For this reason, various dust boots all have been installed on lock, but these dust boots all exist the shortcoming of the bad and operating characteristic difference of closed performance, usually always leave an aperture or slit, rainwater, dust all enter in the lock from these holes, crack at an easy rate, stop up or the corrosion lock core, make it and normally to lock or to open; Vibrations that have, then dust boot just comes off owing to insecure, does not have dustproof effect; Have when opening, quickly upset in the past, stressed bigger, number of times is once many damages easily.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes above-mentioned existence, and a kind of novel cover of dust of brake lock is provided.
The technical solution of the utility model is:
The car lock cover of dust of stopping, the cover of dust lower end is a shaft hole, left crect ear, the right crect ear of a side are connected on shaft hole and the lock body, its major technique be characterised in that in rotating shaft, set gradually hollowly recessedly take turns, hollow cam, spring, set pin passes and hollowly recessedly takes turns, the hollow part of hollow cam, spring, hollow recessed the wheel and the staggered engagement of hollow cam concave, convex, and the hollow recessed afterbody of taking turns is non-circular structure, with the non-circular structure coupling of left crect ear, hollow cam afterbody also is non-round structure.
Advantage of the present utility model and effect are the leak tightnesss of having strengthened cover of dust, and be simultaneously easy and simple to handle, and the amplitude of upset can reach 180 degree, especially with the supporting use of various brake locks, can prolong the service life of brake lock greatly, also brings convenience to the customer.
The utility model is described in further detail below in conjunction with drawings and Examples:
Description of drawings
Fig. 1---the utility model structural principle scheme drawing.
The specific embodiment
As shown in Figure 1:
Lock body 1 upper end one side is provided with left crect ear 2, right crect ear 3, and left crect ear 2 and right crect ear 3 are hollow, but mount pin 4; Cover of dust 5 preceding lower ends are shaft holes 6, set gradually from left to right in it and hollowly recessedly take turns 7, hollow cam 8, spring 9; Hollow recessed 7 afterbodys of taking turns are non-circular structures, with the non-circular structure of left crect ear 2 size coupling, promptly hollowly recessedly take turns 7 afterbodys to insert left crect ear 2 backs just rotatable, as long as can not rotate, other structure can, promptly get final product so long as not circular configuration; Hollow recessed take turns 7 front portions be have recessed have protruding, the front portion of hollow cam 8 also be have recessed have protruding, with hollow recessed take turns 7 the coupling, can intermesh meshes together; The afterbody of hollow cam 8 also is a non-circular structure, is placed in the shaft hole 6, can not produce relative motion with shaft hole 6, and (level) moves before and after can only doing in shaft hole 6; Spring 9 one ends withstand on the afterbody of hollow cam 8, and the other end withstands on the right crect ear 3; Shaft hole 6 embeds between left crect ears 2 and the right crect ear 3, inserts set pin 4, set pin 4 successively from left crect ear 2, hollowly recessedly take turns 7, the hollow position of hollow cam 8 and spring 9 passes, in right crect ear 3, thereby shaft hole 6 and lock body 1 are rotationally connected.
When needs lock car (supposing that original cover of dust 5 closes), earlier cover of dust 5 is started gently, this moment, shaft hole 6 was outwards done the arc rotation; Because left crect ear 2, hollowly recessedly take turns 7 and maintain static, so shaft hole 6 and hollow recessedly relatively rotate between taking turns 7, promptly shaft hole 6 is recessedly taken turns 7 and is rotated around hollow; And, in shaft hole 6, make shaft hole 6 not rotate again around hollow cam 8 because hollow cam 8 afterbodys are non-round structures, and there is not relative motion between the two, shaft hole 6 can only be with hollow cam 8 to rotate together; At this moment, hollowly recessedly take turns 7 and do not rotate, and hollow cam 8 rotates, and makes original the two ingear state be damaged the two separation; Because hollow cam 8 afterbodys head on spring 9, the elastic force that can overcome spring 9 is made parallel motion in shaft hole 6 again, so hollow cam 8 overcomes spring 9 pressure and translation backward, breaks away from and hollow recessed 7 the engagement of taking turns, and cover of dust 5 is opened.
When cover of dust 5 is closed, hollow cam 8 is along with original position is got back in the rotation of shaft hole 6, under the elastic force effect of spring 9, again with hollow recessed 7 engagements again of taking turns, this moment, cover of dust 5 was in relative to the situation that can not rotate, thereby cover of dust 5 can't be opened because of being given a shock.

Claims (2)

1. the car lock cover of dust of stopping, the cover of dust lower end is a shaft hole, left crect ear, the right crect ear of a side are connected on shaft hole and the lock body, it is characterized in that in rotating shaft, setting gradually hollowly recessedly take turns, hollow cam, spring, set pin passes and hollowly recessedly takes turns, the hollow part of hollow cam, spring, hollow recessed the wheel and the staggered engagement of hollow cam concave, convex, and the hollow recessed afterbody of taking turns is non-circular structure, with the non-circular structure coupling of left crect ear, hollow cam afterbody also is non-round structure.
2. the car according to claim 1 lock cover of dust of stopping is characterized in that spring one end withstands on the rear portion of hollow cam, and the other end withstands on the right crect ear on the lock body.
