Abstract
The utility model provides a detachable isolation piston and a gas spring thereof. When the piston seat is worn, the piston seat is only required to be disassembled and replaced by a new piston seat; the bracket can be continuously used, so that the cost is reduced; and when in injection molding, only the piston seat needs to be processed, and compared with the traditional process of integrally injection molding the piston seat and the bracket, the cost is further reduced.
Description
Technical Field
The utility model relates to the technical field of gas springs, in particular to a detachable isolation piston and a gas spring thereof.
Background
Chinese patent CN2533332Y discloses an isolating piston, which is formed by molding a rigid bracket and a piston seat coated on the rigid bracket and having a certain elasticity into an integral structure.
During production, the bracket and the piston seat are required to be integrally formed and processed, so that the cost is high; and when the piston seat is worn and replaced, the piston seat needs to be replaced integrally, and waste is caused.
Therefore, how to overcome the above-mentioned drawbacks is a problem to be solved by the person skilled in the art.
Disclosure of Invention
In order to solve the technical problems in the background technology, the utility model discloses a detachable isolation piston and a gas spring thereof.
The utility model provides a detachable isolation piston which comprises a rigid support and a piston seat wrapping the support, wherein the support and the piston seat are detachably connected in a clamping manner.
When the piston seat is worn, the piston seat is only required to be disassembled and replaced by a new piston seat; the bracket can be continuously used, so that the cost is reduced; and when in injection molding, only the piston seat needs to be processed, and compared with the traditional process of integrally injection molding the piston seat and the bracket, the cost is further reduced.
The specific structure of piston seat and support joint is: the inner wall of the piston seat is provided with a clamping groove; the outer wall of the bracket is provided with a clamping ring which is clamped with a clamping groove.
Further, the opening end of the piston seat is also provided with an inward flanging; the bracket is clamped between the bottom of the piston seat and the inner flanging. The arrangement of the inner flanging limits the mounting of the bracket, so that the stability of the mounting structure of the bracket and the piston seat is improved.
Because the support is difficult to insert into the piston seat, the further design is: the inner end of the support is provided with an outer chamfer, and the bottom of the piston seat is provided with an inclined plane matched with the outer chamfer, so that the inclined plane is attached to the outer chamfer.
When the support is inserted, the support can be blocked by the clamping ring, and based on the blocking, the further design is that: the end face of the snap ring, which is close to the outer chamfer angle, is set to be a guiding inclined plane which is obliquely arranged.
The utility model also provides a gas spring which comprises a cylinder body, wherein a detachable isolation piston is arranged in the cylinder body. In this way, the cost of the gas spring is reduced.
Drawings
The utility model will be further described with reference to the drawings and examples.
FIG. 1 is a front cross-sectional view of an isolation piston;
FIG. 2 is a front cross-sectional view of the gas spring;
in the figure: 1. a bracket; 2. a piston seat; 3. a clamping groove; 4. a clasp; 5. an inner flanging; 6. an outer chamfer; 7. a guide slope; 8. a cylinder body.
Detailed Description
The utility model will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic representations which merely illustrate the basic structure of the utility model and therefore show only the structures which are relevant to the utility model.
Embodiment one:
as shown in fig. 1, the utility model discloses a detachable isolation piston, which comprises a rigid support 1 and a piston seat 2 coating the support 1, wherein the inner wall of the piston seat 2 is attached to the outer wall of the support 1.
The inner wall of the piston seat 2 is provided with a clamping groove 3; the outer wall of the bracket 1 is provided with a clamping ring 4 of a clamping groove 3, so that the bracket 1 and the piston seat 2 are detachably connected in a clamping manner.
When the piston seat 2 is worn, only the piston seat 2 is detached and replaced by a new piston seat 2; the bracket 1 can be continuously used, so that the cost is reduced; in addition, during injection molding, only the piston seat 2 is required to be processed, and compared with the traditional process of integrally injection molding the piston seat 2 and the bracket 1, the cost is further reduced.
Embodiment two:
the difference from the first embodiment is that: the open end of the piston seat 2 is also provided with an inward flange 5; the bracket 1 is clamped between the bottom of the piston seat 2 and the inner flanging 5. The arrangement of the inward flanging 5 limits the installation of the bracket 1, so that the stability of the installation structure of the bracket 1 and the piston seat 2 is improved.
Embodiment III:
compared with the embodiment, the difference is that: the inner end of the bracket 1 is provided with an outer chamfer 6, and the bottom of the piston seat 2 is provided with an inclined plane matched with the outer chamfer 6, so that the inclined plane is attached to the outer chamfer 6. When the support 1 is inserted into the piston seat 2, the outer chamfer 6 plays a guiding role, so that the support 1 is conveniently inserted into the piston seat 2.
Embodiment four:
compared with the three phases of the embodiment, the difference is that: the end face of the snap ring 4 close to the outer chamfer 6 is provided with a guide inclined plane 7, and the guide inclined plane 7 is obliquely arranged. When the support 1 is inserted into the piston seat 2, the clamping ring 4 plays a guiding role in the guiding inclined plane 7, and can be smoothly inserted into the piston seat 2.
Fifth embodiment:
as shown in fig. 2, the utility model also discloses a gas spring, which comprises a cylinder body 8, wherein a detachable isolation piston is arranged in the cylinder body 8. In this way, the cost of the gas spring is reduced.
With the above-described preferred embodiments according to the present utility model as an illustration, the above-described descriptions can be used by persons skilled in the relevant art to make various changes and modifications without departing from the scope of the technical idea of the present utility model. The technical scope of the present utility model is not limited to the description, but must be determined according to the scope of claims.
