Pipe generated noise in telescopic process is equipped with bushing between inner tube and outer tube.
And the bushing that the prior art is arranged between inner tube and outer tube is mostly split type, by two halfpipe institutes
Composition, the bushing being made of two tubuloses are fixedly mounted on by fixing piece on the inner wall of outer tube；In addition, in order to improve outer tube
Sealing performance between inner tube is equipped with sealing shroud on the front end of outer tube, and the sealing shroud of the prior art also passes through
Fixing piece is fixedly mounted on the front end of outer tube；The following can be brought insufficient using the above structure：1. it needs on outer tube
Increase work punching operation, so as to stationary bushing and sealing shroud；2. part kind is more, input mold is more, and needs to produce respectively,
Of high cost, efficiency is low；3. in electronic strut assembling process, bushing and sealing shroud assembling are relatively difficult, and work efficiency is low；4. bushing
It is bad with the fixed effect of sealing shroud, there is the risk to come off.
However in view of the deficiencies of the prior art, it is necessary to develop a kind of reasonable, the simple in structure, production efficiency of design by developer
It is high, at low cost, completely eliminate the situation that split type bushing and sealing shroud are fallen off, service life length is used for electronic support
The bushing of bar.
Utility model content
Existing in the prior art to solve the problems, such as, it is reasonable, simple in structure, raw that the utility model aim provides a kind of design
Produce it is efficient, at low cost, completely eliminate the situation that split type bushing and sealing shroud are fallen off, service life length is used for
The bushing of electronic strut.
For solution more than technical problem, what the utility model was realized using following technical scheme：
A kind of bushing for electronic strut, including whole bush body in a tubular form, which is characterized in that in the bushing
The bottom of body is equipped with force structure, and the force structure is close on bearing block under the force of a spring, in the bushing
The front end of body is equipped with cage-shaped structure, and encapsulated sealing shroud is molded with by secondary in the cage-shaped structure.
In a preferred embodiment of the utility model, the force structure includes being arranged on the bottom of bush body
Stress ring, on the inner ring surface of the stress ring be equipped with annular convex platform.
In a preferred embodiment of the utility model, the cage-shaped structure by ring body, bush body front end and
More supporting rods being arranged between ring body and the front end of bush body are formed.
In a preferred embodiment of the utility model, the sealing shroud is fabricated using polyester elastic materials.
Compared with prior art, the utility model has the following advantages using the above structure：
1. outer tube reduces punching operation, production cost is not only reduced, and also improves production efficiency；
2. bush body is made to be combined into an entirety with sealing shroud, reduce number of assembling steps, save built-up time, improve
Production efficiency reduces management cost；
3. for integral bushings compared with split type bushing, assembling process is relatively simple, packaging efficiency is higher；
4. completely eliminating the situation that split type bushing and sealing shroud are fallen off, failure rate is reduced, improving makes
Use the service life.
Description of the drawings
It in order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only

Specific embodiment
In order to which the technical means, creative features, achievable purpose and effectiveness for realizing the utility model are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
With reference to shown in Fig. 1-Fig. 4, a kind of bushing for electronic strut for being provided in figure, including bushing integrally in a tubular form
Body 100.
Bush body 100 is arranged between outer tube and inner tube, and force structure is equipped in the bottom of bush body 100 110
200, force structure 200 is close on bearing block under the force of a spring.
Force structure 200 includes the stress ring 210 being arranged on the bottom 110 of bush body 100, and the bottom of spring applies
Pressure makes it be close on bearing block in stress ring 210, and outer tube is fixed on by way of indentation on bearing block, bushing
With outer tube using bearing block as positioning matrix, adopting the structure can make between bushing and outer tube more securely, reliably, not only
