Abstract

The utility model relates to a front shock absorber of a bicycle, which is characterized in that the projected part of the middle of a vertical pipe of a front fork is provided with an upper block and a lower block, and then, springs can be prevented from moving upwards; a spline outer slot is formed on the lower end of the vertical pipe of the front fork, and a spline inner slot is formed on the shoulder of the front fork; after the spline inner slot and the spline outer slot are engaged, the vertical pipe of the front fork can slide up and down, and the bicycle can be flexibly turned; a lower block for the springs is arranged on the upper end of the middle of the shoulder of the front fork and is used for sheathing the springs, the diameter of a pad needs to be larger than that of the vertical pipe of the front fork, and an upper top screw bolt is screwed at the bottom of the vertical pipe of the front fork. The front shock absorber has the advantages of simple technology and high safety during application.

Description

Bicycle's front shock-absorber

The utility model belongs to automatic shock-proof device

Existing automatic shock-proof device all is installed on the bicycle front fork leg, and front-wheel easily produces double swerve, phenomenons such as bicycle directional, crank occur, influences rider's safety.

The utility model is will design a kind of Shock absorber to be installed in bicycle front fork shoulder with between the front fork standpipe, and front-wheel can double swerve, the automatic shock-proof device that rider's safety factor increases.

The utility model is finished as follows, there is boss to be called retaining up and down in the middle of the vertical tube of front fork, its effect is the following retaining that can do in six of the front forks, spring is moved on not understanding, make the form of spline water jacket at the end portion of vertical tube of front fork, spline inside groove form is made in the middle part of front fork shoulder, sliding up and down after both engagements can be freely, the slip amplitude is decided on the length of telescopic spring length and spline water jacket, turning of bicycle also nimbly and freely, retaining one spring is play arranged at bicycle front fork shoulder top, and spring is moved in not understanding, and it is front fork to be takeed on can not separate with vertical tube of front fork that the work of last top fastening bolt has.

Compared with the prior art the utility model has easy for installationly, phenomenons such as front-wheel double swerve and direction and crank can not occur during use, and rider's safety factor is improved, and technology is simple during manufacturing, and having must be the society and economy benefit.

Below in conjunction with accompanying drawing the utility model is further described

Fig. 1 is a structural representation of the present utility model

Fig. 2 is a vertical tube of front fork structural representation of the present utility model.

Fig. 3 is a front fork shoulder structural representation of the present utility model

In conjunction with Fig. 1 Fig. 2 Fig. 3, the effect of retaining (1) is that the following retaining in the front fork spare can not moved down up and down, spring does not move on not understanding yet, the lower end part of vertical tube of front fork is made spline water jacket (2) front fork shoulder middle part and is made spline inside groove (3), water jacket is engageable in the spline, the spring on front fork shoulder top retaining (4) down can make spring move in not understanding, and the pad (7) of last top fastening bolt (6) should be greater than the diameter of vertical tube of front fork, and its effect is front fork to be takeed on can not separate with vertical tube of front fork.

During installation, earlier put spring (5) at second position of vertical tube of front fork, be the lower part of vertical tube of front fork the middle part of the position insertion front fork shoulder of spline water jacket (2) again, it is spline inside groove (3) position, both are meshed, spring (5) is inserted in retaining (4) under the spring, and shell tool (7) is screwed in the vertical tube of front fork bottom to last top fastening bolt (6) again and gets final product.

Implement the utility model technology, safe and convenient to use, concrete specifications and models can depend on the needs.

Claims

1, a kind of bicycle front shock-proof device device is characterized in that retaining (1) is up and down withstood in the upper end of spring (5), and the lower end is enclosed within and keeps off under the spring on (4), the spline water jacket (2) of front fork tube lower end and middle spline water jacket (3) engagement of front fork shoulder.

2, according to the bicycle front shock-proof device device of claim 1 regulation, it is characterized in that the diameter of pad (7) should be greater than the diameter of bicycle front fork pipe, last top stud (6) is spun on the bottom of vertical tube of front fork.
