CN202879724U - Brake grip set capable of being used for springback quick position returning after being pressed - Google Patents

Abstract

A brake grip set capable of being used for springback quick position returning after being pressed is composed of a brake base and a grip, wherein the brake base is fixed in a cross handle of a bicycle frame, and the grip is assembled in the brake base in a pivot mode. Two round through holes are formed before a pivot round hole of the grip. A concave opening is arranged at the position, close to the pivot round hole, of an opening of the brake base, and a concave opening groove which is in a concave shape is formed in the inner wall of the concave opening. When the grip is placed in the opening of the brake base, a pivot pin is arranged in from the pivot round hole in a penetrating mode, at the same time, the pivot pin penetrates into a hollow position of a torsion spring, a set of sleeves is arranged in the concave space between two the two round penetrating holes, and a spring body and a pressing button are assembled in each sleeve. When a user pushes and presses the press button on the grip to the concave opening groove in the inner wall of the concave opening, the grip can be pushed forward to loose a brake line, then a brake clamp stretches for dismantling and replacing a wheel, then when the user pulls the grip again, the press button can automatically spring back and return a position to the concave opening and enables the brake clamp to return to a set position, so that the springback quick position returning can be achieved after the brake grip set is pressed, operation time is saved, and effect is improved.

Description

Can after pressing, do playback the fast Brake lever group of usefulness of spring-go

Technical field

The utility model is a kind ofly can do playback the fast Brake lever of usefulness of spring-go after pressing, by one be fixed on brake mount and in the vehicle frame cross handle be pivoted be assembled in the brake mount handle in conjunction with after, when the user turns round lower, can cause brake cable lax and brake binder done open for changeing wheel in the signature of operation in the handle, give again when pulling handle afterwards and can automatically reset, after pressing, do playback the fast saving operating time effect of usefulness of spring-go to reach to have.

Background technology

Press, about the relation of brake binder in the bicycle and handle, by a brake cable both are done binding, make that its pressure by handle is held under the start, brake binder at once does to paste to touch to wheel and do, and reaches the brake purpose; Then need when changeing brake cable to unclasping out, open-shaped conveniently the doing of brake binder could being changed when wheel being done, but in the middle of such operating process, all need spend some not include the short time with present car body framework, especially when contest, must strive a second second especially, not allow slightly to have indiscreet and negligent.

Therefore, then give for above situation applicant and to develop the utility model case, and then propose the application of this patent.

Summary of the invention

The purpose of this utility model is to provide a kind of can do playback the fast Brake lever group of usefulness of spring-go after pressing, it is simple in structure, and is easy to loading and unloading, can save the time that changes, and improves operating efficiency.

For achieving the above object, the utility model discloses and a kind ofly can after pressing, do playback the fast Brake lever group of usefulness of spring-go, be fixed on brake mount and in the vehicle frame cross handle handle that is assembled in the brake mount that is pivoted by one and consisted of; It is characterized in that:

Be a recess at the opening of brake mount near in the position in pivot hole, the inwall of recess is provided with a recessed fluting that is recess; Bore a hole and before the pivot circular hole of handle, be provided with two circles, and this trunnion penetrates the vacancy of a torque spring when placing a trunnion by the pivot circular hole when handle places the opening of brake mount, so that these torque spring two ends are spacing in brake mount and handle respectively, in addition the sinking space between the two circle perforation in pivot circular hole the place ahead of handle are provided with a sleeve, and assembling one spring body and signature are turned round in sleeve; After making brake cable pass the sleeve of assembling in the circumference perforation to the handle behind the brake mount, when the user when the signature of pushing on this handle turned round, this handle can be pushed away forward and form the lax of brake cable, and then brake binder is done open and come for changeing wheel, can appliance for releasing single involution position when pulling handle more afterwards to the location, can after pressing, do playback the fast saving operating time effect of usefulness of spring-go to reach tool.

Pass through said structure, the utility model when the user when the signature of pushing on this handle turned round, can this handle be pushed away forward and cause relaxing of brake cable, and then brake binder is done open and come for changeing wheel, can appliance for releasing single involution position when pulling handle more afterwards to the location, so can after pressing, do playback the fast saving operating time effect of usefulness of spring-go to reach tool.

The specific embodiment

At first, please cooperate shown in the detailed description of consulting Fig. 1, Fig. 2, Fig. 3: the utility model is a kind of can do playback the fast Brake lever group of usefulness of spring-go after pressing, and is fixed on brake mount 2 and in vehicle frame 1 cross handle 11 handle 3 that is assembled in the brake mount 2 that is pivoted by one and is consisted of; Wherein this brake mount 2 is screwed on the collar 2B by a bolt 2A, again by collar 2B circle bundle on cross handle 11, and be a recess 23 at the opening 21 of brake mount 2 near in the positions in pivot hole 22, and be provided with a recessed fluting 24 that is recess at the inwall of recess 23; Bore a hole 32 and before the pivot circular hole 31 of handle 3, be provided with two circles, and be the sinking space of U font in inner, and handle 3 places the vacancy 41 that penetrates a torque spring 4 in the trunnion 3A when placing the opening 21 of brake mount 2 and by pivot circular hole 31, so that these torque spring 4 two ends are spacing in brake mount 2 and handle 3 respectively, other is provided with a sleeve 5 at the sinking space between the two circle perforation 32 in pivot circular hole 31 the place aheads of handle 3, and turns round 5B in sleeve 5 interior assembling one spring body 5A, signature; So, brake cable 6 passes behind the brake mount 2 behind the sleeve 3B that assembles to the handle 3 front circumferences perforation 32 (such as Fig. 4 A, Fig. 4 B, Fig. 4 C), when 5B is turned round in the signature of user on this handle 3 of pushing, think when this signature is turned round 5B and then then entered the recessed fluting 24 of recess 23 inwalls by original position in recess 23 (such as Fig. 5 A), so just this handle 3 can be pushed away (such as Fig. 5 B) forward, think lax (such as Fig. 5 C) that cause brake cable 6, and then brake binder 7 can be done and open for changeing wheel 8 operations, pulling afterwards handle 3 can make to give as security and turn round 5B and be subjected under the elastic force booster action of spring body 5A again, appliance for releasing single involution position is to recess 23 and make brake binder 7 also return back to the location, so can do playback the fast saving operating time effect of usefulness of spring-go to reach tool after pressing.

To sum up institute is old, thinks that by the utility model doing spring-go after pressing playbacks under the saving operating time effect of usefulness fast.
