Abstract

The utility model relates to an improvement of electric bicycle damper, which comprises an upper tie-in embedded with a dust-proof sheath and an inner pipe, a lower tie-in for fastening external pipe and an elastic assemble arranged in the external pipe, wherein, the dust-proof sheath is assembled with the external pipe. The elastic assemble comprises a spring, a spring rubber cushion arranged on two ends of the spring and an inner six angle core stick penetrating in the spring rubber cushion and connected with the lower tie-in. The utility model is characterized in that an art hole is arranged on axle direction of the upper tie-in; an inner pipe is embedded on a cylinder console on lower end of the upper tie-in. A cylinder type inner sliding sheath is arranged in the back end of the upper tie-in. The cylinder type inner sliding sheath matches with the outer pipe wall of the cylinder console at lower end of the lower tie-in by kinetic friction. The utility model is convenient for detachment with high concentric degree, thereby guaranteeing effectively shock absorbing of the damper. The utility model has no break welding point in impact experiment with less spring deformation and without damage of other accessories.

Description

The Electrical Bicycle Shock absorber

Technical field

The utility model relates to a kind of improvement of Electrical Bicycle Shock absorber.

Background technology

Known automatic shock-proof device is extensively adopted on the Electrical Bicycle.At the shock-absorbing context buffer some creation have been arranged, as number of patent application is a kind of automatic shock-proof device of (01221023.4), comprise spring, front and back Connection Block, tubular shell has been threaded between Connection Block, spring places in the housing, back Connection Block lower end is threaded with tubular shell, and socket bolt connects gland, and spring and back Connection Block are fixed.But present known Shock absorber mostly is by the plug of socket bolt as the shock-proof spring upper and lower displacement, because so the long-term compression work of Shock absorber is the flexible distortion of this socket bolt, and do not have the damping, buffering effect, if change interior fittings, the necessary special tool that uses can dismounting and change.Also be not resolved up to now.

The utility model content

Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of the improvement to reach preferable shock-absorbing buffering effect, easy-to-mount Electrical Bicycle Shock absorber after its structure.

Its technical matters that solves the utility model realizes by the following technical solutions: a kind of Electrical Bicycle Shock absorber, comprise the top connection that is embedded with dust protecting cap and interior pipe, the lower adaptor of fastening outer tube and place elastic parts in the outer tube, dust protecting cap and outer tube suit, described elastic parts have spring, place both ends of the spring the spring glue gasket and in hexagonal sticks run through therebetween and spin with lower adaptor; It is characterized in that: the axial location of described top connection is provided with the auxiliary hole that connects with hexagonal sticks, pipe is embedded in the top connection lower end on the cylinder table in described, pipe rear end is socketed with the cartridge type inner sliding sleeve in it, and the cartridge type inner sliding sleeve cooperates with outer tube wall face cliding friction on being fastened on lower adaptor lower end cylindrical pylon.

Be provided with the noise reduction pad between described cartridge type inner sliding sleeve bottom and the interior hexagonal sticks.

Based on above structure, during dismounting, inner-hexagon spanner passes the auxiliary hole of top connection and can easily interior hexagonal sticks be tightened or pull down, and making up and down, blank area separates; Because cartridge type inner sliding sleeve and outer tube are bearing fits, have guaranteed the concentricity of Shock absorber effectively, have alleviated the reciprocal load of the internal hexagonal sticks of spring, make it not yielding, thereby guarantee the damping, buffering effect of Shock absorber effectively.The utility model in 150 kilograms impact experiment, compress 100,000 times continuously after, its solder joint non-cracking, spring deflection is little, the equal zero damage of all the other accessories.

Description of drawings

Fig. 1 is the scheme drawing of the utility model structure;

Fig. 2 is a schematic appearance of the present utility model.

The specific embodiment

Below in conjunction with drawings and Examples foundation the utility model structure and effect are elaborated.

As shown in Figure 1, the utility model comprises the top connection 1 that is embedded with dust protecting cap 3 and interior pipe 2, be fastened with the lower adaptor 10 and the elastic parts that places in the outer tube 5 of outer tube 5, dust protecting cap 3 is sleeved on outside the outer tube 5, described elastic parts has spring 8, place spring 8 two ends spring glue gasket 7 and in hexagonal sticks 9 run through therebetween and spin with lower adaptor 10 screw threads, the pad 12 that connects to ground is housed and to lock screw 13 on the upper and lower joint; The axial location of described top connection 1 is provided with the auxiliary hole 14 that connects with hexagonal sticks, the upper end and the top connection 1 lower end cylinder table of interior pipe 2 are chimeric fastening, in pipe 2 lower end be socketed with cartridge type inner sliding sleeve 4 and cooperate with outer tube 5 wall cliding frictions on being fastened on lower adaptor lower end cylinder table, described cartridge type inner sliding sleeve 4 bottoms place between noise reduction pad 6 and the spring glue gasket 7, interior hexagonal sticks 9 run through wherein spin with lower adaptor 10 screw threads after, upper and lower joint two parts are fused.During dismounting, inner-hexagon spanner passes the auxiliary hole of top connection and can easily interior hexagonal sticks be tightened or pull down, and making up and down, blank area separates; Because cartridge type inner sliding sleeve and overcoat are bearing fits, have guaranteed the concentricity of Shock absorber effectively, have alleviated the reciprocal load of the internal hexagonal sticks of spring, make it not yielding, thereby guarantee the cushioning effect of Shock absorber effectively.

Claims

1, a kind of Electrical Bicycle Shock absorber, comprise the top connection that is embedded with dust protecting cap and interior pipe, the lower adaptor of fastening outer tube and place elastic parts in the outer tube, dust protecting cap and outer tube suit, described elastic parts have spring, place both ends of the spring the spring glue gasket and in hexagonal sticks run through therebetween and spin with lower adaptor; It is characterized in that: the axial location of described top connection is provided with the auxiliary hole that connects with hexagonal sticks, pipe is embedded in the top connection lower end on the cylinder table in described, pipe rear end is socketed with the cartridge type inner sliding sleeve in it, and the cartridge type inner sliding sleeve cooperates with outer tube wall face cliding friction on being fastened on lower adaptor lower end cylindrical pylon.
