Abstract
The invention discloses a connecting rod type suspension fork assembly of a bicycle. The connecting rod type suspension fork comprises a front fork vertical pipe and front fork legs. A front fork base which extends towards the front slanting direction is fixedly connected to the outer side of the lower portion of the front fork vertical pipe, a front leg base which extends toward the rear slanting direction is arranged at the tops of the front fork legs, two connecting rods are hinged to the top end of the front fork base, the two connecting rods are hinged to the fork leg base respectively, a limiting block is fixedly arranged inside the front fork vertical pipe, a compression spring is arranged at the lower end of the limiting block, a compaction block is arranged at the lower end of the compression spring, a stop dog is arranged on the inner wall of the portion, below the compaction block, of the front fork vertical pipe, and therefore the compaction block moves up and down between the limiting block and the stop dog along the inner wall of the front fork pipe under the elastic force of the compression spring. A connecting rod is arranged between the bottom of the compaction block and the fork leg base, one end of the connecting rod is hinged to the compaction block, and the other end of the connecting rod is fixedly connected with the fork leg base. The connecting rod type suspension fork assembly of the bicycle effectively achieves buffering and shock absorption when the compression spring is compressed by the simple connecting rod structure, and is low in cost, low in weight, and suitable for being ridded in roads of cities and countries.
Description
Technical field
The present invention relates to a kind of shock-proof front-fork assembly of bicycle, specifically, is a kind of link-type shock-proof front-fork assembly assembly of bicycle.
Background technology
Along with improving constantly of people's living standard, Green Travel, recreation and body-building have become a part for people's daily life.Mountain bike because of profile rough, front fork band shock-absorbing, is subject to many customers and likes.This front fork is two-tube shock-proof front-fork assembly, a pipe be equipped with shock-absorbing medium as: spring or high pressure gas, another pipe is equipped with hydraulic oil, in order to regulate shock-absorbing damping.This makes front fork volume large, Heavy Weight, and lubrication and seal difficulty strengthens, and manufacturing cost increases.This class anti-vibration bicycle is applicable to walking mostly on ups and downs ground, to alleviate vibrations and to impact.But for city and rural road surface, ride, mountain bike front fork is too heavy, and cost is too high.People wish a kind of, shock-proof front-fork assembly with low cost.
Summary of the invention
Technical matters to be solved by this invention is that a kind of link-type shock-proof front-fork assembly assembly of bicycle simple in structure, light, easy to operate, with low cost is provided.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of link-type shock-proof front-fork assembly assembly of bicycle, comprise vertical tube of front fork and fork blade, the lower outside of vertical tube of front fork be fixedly connected with below reaching out tiltedly front-fork seat, at fork blade top, arrange and be fixedly connected with the fork leg seat stretching to above retreading, at hinged two connecting rods in the top of front-fork seat, two connecting rods are hinged with fork leg seat respectively again; In vertical tube of front fork, fix a limiting stopper, Compress Spring is equipped with in limiting stopper lower end, Compress Spring lower end is provided with a compact heap, on the inwall of the vertical tube of front fork of compact heap below, be provided with block, make compact heap under the elastic force of Compress Spring, along vertical tube of front fork inwall, between limiting stopper and block, move up and down; Between compact heap bottom and fork leg seat, be provided with a connecting rod, connecting rod one end and compact heap are hinged, and the other end and fork leg seat connect firmly.
Described block is to be screwed in the inboard jam nut with through hole in vertical tube of front fork bottom, and connecting rod is through the through hole of jam nut.
On described fork leg seat, be provided with the Connection Block of the oblique upper that reaches out, be connected to connecting rod between compact heap and fork leg seat and the Connection Block on fork leg seat and mutually connect firmly with square cotter.
The invention has the beneficial effects as follows: by simple bar linkage structure Compress Spring, effectively reach bumper and absorbing shock, cost is low, lightweight, be applicable to city and rural road surface is ridden.
Accompanying drawing explanation
Fig. 1 is the block diagram of the link-type shock-proof front-fork assembly assembly of bicycle of the present invention.
Fig. 2 is the cutaway view of the link-type shock-proof front-fork assembly assembly of bicycle of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail:
As shown in Figure 1, 2, the link-type shock-proof front-fork assembly assembly of bicycle of the present invention, comprise vertical tube of front fork 1 and fork blade 12, the lower outside of vertical tube of front fork 1 be fixedly connected with below reaching out tiltedly front-fork seat 2, at fork blade 12 tops, be fixedly connected with the fork leg seat 4 stretching to above retreading, on the top of front-fork seat 2, hinged two connecting rod 3, two connecting rods 3 are hinged with fork leg seat 4 respectively again; The interior limiting stopper 5 of fixing of vertical tube of front fork 1, Compress Spring 6 is equipped with in limiting stopper 5 lower ends, Compress Spring 6 lower ends are provided with a compact heap 7, on the inwall of the vertical tube of front fork 1 of compact heap 7 belows, be provided with block, make compact heap 7 under the elastic force of Compress Spring 6, along vertical tube of front fork 1 inwall, between limiting stopper 5 and block, move up and down; Between compact heap 7 bottoms and fork leg seat 4, be provided with a connecting rod 9, connecting rod 9 one end and compact heap 7 are hinged, and the other end and fork leg seat 4 connect firmly.
Preferably, block is the jam nut 8 with through hole that is screwed in vertical tube of front fork 1 inboard, bottom described in the present embodiment, and connecting rod 9 is through the through hole of jam nut.
Preferably, be provided with the Connection Block 10 of the oblique upper that reaches out described in the present embodiment on fork leg seat 4, the connecting rod 9 being connected between compact heap 7 and fork leg seat 4 connects firmly mutually with the Connection Block 10 use square cotters 11 on fork leg seat 4.
When pavement roughness, impulsive force makes fork leg seat 4 upwards rotate in the hinged place of two connecting rods 3, and connecting rod 9, because connecting firmly with fork leg seat 4, also moves up together, and hinged compact heap 7 is moved up in vertical tube of front fork 1, Compress Spring 6, and reach buffering effect.
Above-described embodiment is only for illustrating technological thought of the present invention and feature, its object is to make those skilled in the art can understand content of the present invention and implement according to this, can not only with the present embodiment, limit the scope of the claims of the present invention, be equal variation or the modification that all disclosed spirit is done, still drop in the scope of the claims of the present invention.
