Description

Technical Field

[0001] This utility model relates to the field of cylinder accessories technology, and more specifically to a rubber and plastic plug for cylinders. Background Technology

[0002] As a core actuator in the pneumatic field, the cylinder mainly consists of a cylinder barrel, front cover, rear cover, piston, and piston rod. During operation, the piston reciprocates along the cylinder barrel axially under the drive of compressed gas, achieving power output. In this system, the sealing performance directly affects the cylinder's working efficiency and service life, and the performance of the rubber and plastic plug, as a key sealing element, has a significant impact on the entire pneumatic system.

[0003] As shown in the prior art published in CN215521465U, although this prior art uses an elastic extrusion sheet to offset external extrusion force, reducing the impact of impact, and a high-temperature resistant friction pad to reduce friction, and employs a composite material matrix with heat insulation, anti-corrosion, and wear-resistant layers to enhance practicality, providing heat insulation, anti-corrosion, and wear resistance, thus increasing usability and extending service life; and uses a connecting base, requiring the cover plate to be removed, the slide plate to be pulled out using the handle, and then the rubber plug to be pulled out, making it convenient to use and increasing practicality. However, this prior art requires removing the cover plate first, then pulling out the slide plate, and finally pulling the plug. This process involves multiple steps, making it inconvenient to operate in space-constrained installation locations and failing to achieve the goal of rapid maintenance. Furthermore, the operating surface of the slide plate is relatively small, which affects the ease of operation of this prior art. Utility Model Content

[0004] To overcome the aforementioned deficiencies in the prior art, this utility model provides a rubber-plastic plug for a cylinder. By pulling the elastic band upward with two fingers, the elastic band, through the connecting plate, pulls the pressure ring upward, and the pressure ring, along with the plug body, moves upward, thereby pulling out the plug body. Because the elastic band can deform, the upward pulling operation of the elastic band can be performed more effectively, and the large operating surface can effectively ensure the convenience of operation, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rubber-plastic plug for a cylinder, comprising a plug body mounted on the cylinder, wherein the plug body is easily disassembled via an auxiliary component; The auxiliary component includes two connecting plates disposed within the body of the stopper. The two connecting plates are symmetrically distributed about the central axis of the stopper body. Elastic bands are installed on both sides of the top of the two connecting plates, and the same pressure ring is installed at the bottom of the two connecting plates. A spring is provided on the top of the pressure ring, which is sleeved on the outside of the two connecting plates. By pulling the elastic band upward with two fingers, the elastic band pulls the pressure ring upward through the connecting plates, and the pressure ring moves the stopper body upward, thereby pulling the stopper body out. Because the elastic band can deform, it is easier to pull the elastic band upward, and the large operating surface can effectively ensure the convenience of operation.

[0006] In a preferred embodiment, the piston body has an annular cavity and two connecting holes inside. The connecting holes are located at the top of the annular cavity and are connected to the annular cavity. The pressure ring, spring, and two connecting plates are all located inside the annular cavity. The two connecting plates extend into the two connecting holes respectively. The pressure ring, spring, and connecting plates are assembled through the annular cavity and connecting holes to enhance the connection stability between the auxiliary components and the piston body and ensure the convenience of removing the piston body.

[0007] In a preferred embodiment, the top of the plug body has two engaging grooves, and two elastic bands are respectively disposed inside the two engaging grooves. The two engaging grooves are respectively disposed on the side of the two connecting holes that are far apart, and the engaging grooves are connected to the connecting holes. The elastic bands are assembled through the engaging grooves so that the elastic bands are flush with the plug body.

[0008] In a preferred embodiment, the cross-section of both the locking groove and the elastic band is L-shaped, and the depth of the locking groove near the connecting plate is less than the height of the elastic band away from the connecting plate. By setting the elastic band higher than the locking groove, there is enough space to operate the elastic band, thereby improving the convenience of operating the elastic band.

[0009] In a preferred embodiment, the inner and outer walls of the pressure ring are in contact with the inner and outer walls of the ring cavity, respectively. The ring cavity limits and guides the pressure ring, ensuring the stability of the pressure ring during displacement and preventing the pressure ring from tilting or shaking.

[0010] In a preferred embodiment, a pull strap is installed on the side of the elastic band near the connecting plate. The pull strap is located inside the engagement groove. The pull strap improves the ease of lifting the elastic band.

[0011] The technical effects and advantages of this utility model are as follows: 1. By pulling the elastic band upward with two fingers, the elastic band moves the pressure ring upward through the connecting plate, and the pressure ring moves the rubber stopper body upward, thereby pulling out the rubber stopper body. Because the elastic band can deform, it is easier to pull the elastic band upward, and the operating surface is large, which can effectively ensure the convenience of operation. 2. The spring's rebound force pushes the pressure ring inward, and the pressure ring, with the help of the connecting plate, moves the elastic band into the engagement groove, thereby making the elastic band flush with the stopper body, ensuring that the elastic band and the stopper body are flush.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Refer to the instruction manual appendix Figure 1-5 This utility model provides a rubber-plastic plug for a cylinder, including a plug body 1 installed on the cylinder. The plug body 1 can be easily disassembled by an auxiliary component. The auxiliary component includes two connecting plates 2 disposed inside the plug body 1. The two connecting plates 2 are symmetrically distributed about the central axis of the plug body 1. Elastic bands 3 are installed on both sides of the top of the two connecting plates 2, and the same pressure ring 4 is installed at the bottom of the two connecting plates 2. A spring 5 is provided on the top of the pressure ring 4, and the spring 5 is sleeved on the outside of the two connecting plates 2.

[0016] When using the aforementioned plug body 1, the operator assembles the plug body 1 onto the cylinder. This enhances the cylinder's sealing performance, ensures the stability of the cylinder during operation, and guarantees the cylinder's working efficiency and service life.

[0017] When maintaining a damaged stopper body 1, an auxiliary component can be used to easily disassemble the stopper body 1. To ensure the operational stability of the auxiliary component, an annular cavity 6 and two connecting holes 7 are provided inside the stopper body 1. The connecting holes 7 are located at the top of the annular cavity 6 and are connected to the annular cavity 6. The pressure ring 4, spring 5, and two connecting plates 2 are all located inside the annular cavity 6, and the two connecting plates 2 extend into the two connecting holes 7 respectively. In this way, the pressure ring 4, spring 5, and connecting plates 2 can be assembled using the annular cavity 6 and connecting holes 7, ensuring the connection stability between the pressure ring 4, spring 5, and connecting plates 2 and the stopper body 1. This enhances the tightness of the connection between the pressure ring 4, spring 5, and connecting plates 2 and the stopper body 1, thereby facilitating the operation of the auxiliary component to move the stopper body 1.

[0018] When operating the stopper body 1, the operator pulls the elastic band 3 upwards with two fingers. The elastic band 3, through the connecting plate 2, pulls the pressure ring 4 upwards. The pressure ring 4, in turn, compresses the spring 5. As the pressure ring 4 moves upwards, the stopper body 1 also moves upwards, thus pulling the stopper body 1 out. Because the elastic band 3 can deform, the operator can better pull it upwards, thereby enhancing the stability of the operation. Furthermore, the large operating surface effectively ensures ease of operation.

[0019] Meanwhile, to prevent the elastic band 3 from protruding from the plug body 1, two engaging grooves 8 are formed on the top of the plug body 1. The two elastic bands 3 are respectively located inside the two engaging grooves 8, which are located on opposite sides of the two connecting holes 7, and are connected to the connecting holes 7. In this way, the spring 5 can push the pressure ring 4 inward by its rebound force, and the pressure ring 4 can then move the elastic band 3 into the engaging groove 8 by the connecting plate 2, so that the elastic band 3 is flush with the plug body 1, thereby preventing the elastic band 3 from protruding.

[0020] Furthermore, to improve the ease of operation of the elastic band 3, both the cross-section of the engaging groove 8 and the cross-section of the elastic band 3 are L-shaped, and the depth of the end of the engaging groove 8 near the connecting plate 2 is less than the height of the end of the elastic band 3 away from the connecting plate 2. This provides sufficient space to move the elastic band 3, improving the ease of operation. Also, a pull strap 9 is installed on the side of the elastic band 3 near the connecting plate 2, and the pull strap 9 is located inside the engaging groove 8. This allows the operator to operate the pull strap 9 inside the engaging groove 8 and lift the elastic band 3 using the pull strap 9, thereby improving the ease of operation of the elastic band 3.

[0021] To ensure stability during the displacement of the pressure ring 4, the inner and outer walls of the pressure ring 4 are in contact with the inner and outer walls of the ring cavity 6, respectively. This allows the ring cavity 6 to guide and limit the pressure ring 4, thus ensuring stability during displacement and preventing it from tilting.

[0022] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
