Description

Technical Field

[0001] This utility model relates to the field of compressor technology, and in particular to a rubber stopper with a snap-fit ​​mechanism. Background Technology

[0002] Rotary compressors for energy storage and commercial vehicles include a pressure plate mounted on top of the compressor. The pressure plate has an intake port that penetrates both the upper and lower surfaces of the pressure plate. During transportation, to protect the upper surface of the pressure plate, a rubber plug is typically inserted into the intake port. This rubber plug not only blocks the intake port but also covers the upper surface of the pressure plate. After the rubber plug is in place, an inflation needle is inserted into the rubber plug at the intake port position, and nitrogen is injected into the compressor through the needle. This prevents oxidation of internal components and isolates the compressor from external moisture. The rubber plug maintains pressure after the compressor is filled with nitrogen.

[0003] However, current rubber stoppers have the following problems: 1. When inserting rubber stoppers, operators mainly rely on touch to determine whether the rubber stopper is inserted properly. Due to the different touches of different operators, some rubber stoppers are inserted too tightly and are not easy to remove, while some rubber stoppers are not inserted properly and are easy to fall off.

[0004] 2. The depth of the countersunk hole in the air intake is relatively shallow, currently the deepest being 14mm. In addition, a small amount of oil often adheres to the inner wall of the air intake. The oil reduces the friction between the rubber stopper and the inner wall of the air intake, making the rubber stopper easy to be pushed open and fall off by air pressure during transportation.

[0005] 3. During the unpacking process, the packaging material may come into contact with the rubber stopper, causing the rubber stopper to fall off. Utility Model Content

[0006] This invention provides a rubber stopper with a snap-fit ​​mechanism to solve the aforementioned problems associated with rubber stoppers on pressure plates.

[0007] To solve the above-mentioned technical problems, this utility model provides a rubber stopper with snap fasteners, including a body and a rubber stopper; the body includes a cover plate and two snap fasteners, and the body is made of plastic; the cover plate is provided with a through hole penetrating the upper and lower end surfaces of the cover plate, and the lower end surface of the cover plate is used to cover the upper end surface of the pressure plate; the two snap fasteners are arranged opposite to each other and spaced apart on the lower end surface of the cover plate, and the two snap fasteners are used to lock onto the lower end surface of the pressure plate; One end of the rubber plug is embedded in the through hole, and the other end extends to the outer side of the lower end face of the cover plate. The rubber plug is made of rubber.

[0008] Preferably, the through hole is a stepped hole, the upper diameter of the stepped hole is larger than the lower diameter of the stepped hole; one end of the rubber plug is a flat cylindrical shape, and one end of the rubber plug is fixed inside the upper part of the stepped hole.

[0009] Preferably, the diameter of one end of the rubber stopper is equal to the upper diameter of the stepped hole.

[0010] Preferably, the upper end face of the rubber stopper is flush with the upper end face of the through hole.

[0011] Preferably, the lower end face of the cover plate has a downwardly extending flange along the circumferential direction, and the space formed by the flange and the lower end face of the cover plate is used to accommodate the upper end of the pressure plate.

[0012] Preferably, the two buckles are disposed opposite to each other on the two sides of the flange.

[0013] Preferably, the upper and lower surfaces of the cover plate have the same outline shape.

[0014] Preferably, the rubber plug is provided with a blind hole in the axial direction, and the opening direction of the blind hole faces the upper end face of the cover plate.

[0015] Preferably, an annular protrusion is provided on the side of the other end of the rubber stopper, and the protrusion is perpendicular to the axial direction of the rubber stopper.

[0016] Preferably, one end of the rubber stopper and the through hole of the cover plate are fused together to form an integral structure by heat fusion.

[0017] The rubber stopper with a snap-fit ​​provided by this utility model has the following beneficial effects: 1. Easy installation and removal. When installing the rubber stopper with clips, operators only need to press it into place; no other tools are required. The clips will click when fully installed, allowing operators to confirm proper installation by touch and / or sound. Operators can also check the sides of the rubber stopper and the pressure plate to confirm the clips are engaged with the lower end of the pressure plate. To remove the rubber stopper, its elasticity allows for easy removal by simply prying the clips off the pressure plate.

[0018] 2. Not easy to fall off. Because the rubber stopper with the snap fastener is fastened to the pressure plate by the snap fastener, even if there is oil in the air hole on the pressure plate, or if the rubber stopper with the snap fastener is hit by the packaging material, the rubber stopper with the snap fastener is not easy to fall off the pressure plate.

[0019] 3. Facilitates new product development. The pressure plate has a high degree of standardization in the industry, so when developing new products, only the rubber stopper part needs to be updated, while the plastic body part can be used interchangeably. Attached Figure Description

[0032] To make the objectives, advantages, and features of this utility model clearer, the following detailed description of a rubber stopper with a snap-fit ​​mechanism, in conjunction with the accompanying drawings, is provided. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the explanation of the embodiments of this utility model.

[0033] In the description of this utility model, the terms "first," "second," and other qualifiers are added for convenience of description and reference, and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with qualifiers such as "first" and "second" may explicitly or implicitly include one or more of that feature.

[0034] like Figures 1-11 As shown, this embodiment provides a rubber plug 1 with snap fasteners, including a body 11 and a rubber plug 12; the body 11 includes a cover plate 111 and two snap fasteners 112, and the body 11 is made of plastic; the cover plate 111 is provided with a through hole 113 penetrating the upper and lower end surfaces of the cover plate 111, and the lower end surface of the cover plate 111 is used to cover the upper end surface of the pressure plate 2; the two snap fasteners 112 are arranged opposite to each other and spaced apart on the lower end surface of the cover plate 111, and the two snap fasteners 112 are used to lock onto the lower end surface of the pressure plate 2; one end of the rubber plug 12 is embedded in the through hole 113, and the other end extends to the outside of the lower end surface of the cover plate 111, and the rubber plug 12 is made of rubber.

[0035] The rubber stopper 1 with a snap-fit ​​provided in this embodiment has the following beneficial effects: 1. Easy installation and disassembly. When installing the rubber stopper 1 with clips, the operator only needs to press it into place; no other installation tools are required. When the rubber stopper 1 with clips is installed in place, the clip 112 will make a clicking sound, allowing the operator to determine whether the rubber stopper 1 with clips is installed correctly by touch and / or sound. The operator can also check the sides of the rubber stopper 1 with clips and the pressure plate 2 to confirm whether the clip 112 is engaged with the lower end face of the pressure plate 2. When it is necessary to disassemble the rubber stopper 1 with clips, since the body 11 of the rubber stopper 1 with clips has a certain degree of elasticity, the clip 112 can be directly pried off the pressure plate 2 to remove the rubber stopper 1 with clips.

[0036] 2. Not easy to fall off. Because the rubber stopper 1 with the buckle is fastened to the pressure plate 2 by the buckle 112, even if there is oil in the air hole 21 on the pressure plate 2, or if the rubber stopper 1 with the buckle is hit by the packaging material, the rubber stopper 1 with the buckle is not easy to fall off the pressure plate 2.

[0037] 3. Facilitates new product development. The pressure plate 2 has a high degree of standardization in the industry. When developing new products in the future, only the rubber stopper 12 needs to be updated, while the plastic body 11 can be used interchangeably.

[0038] Preferred, such as Figure 6 and Figure 8 As shown, the through hole 113 is a stepped hole, with the upper diameter of the stepped hole being larger than the lower diameter; one end of the rubber plug 12 is a flat cylindrical shape, and one end of the rubber plug 12 is fixed inside the upper part of the stepped hole. Fixing one end of the rubber plug 12 inside the upper part of the stepped hole can improve the firmness between the rubber plug 12 and the cover plate 111.

[0039] Preferred, such as Figure 3 As shown, the diameter of one end of the rubber plug 12 is equal to the upper diameter of the stepped hole. This design can further improve the firmness between the rubber plug 12 and the cover plate 111.

[0040] Preferred, such as Figure 2 and Figure 6 As shown, the upper end face of the rubber stopper 12 is flush with the upper end face of the through hole 113. This design can avoid interference between the upper end face of the rubber stopper 12 and the packaging material.

[0041] Preferred, such as Figure 1 and Figure 11 As shown, the lower end face of the cover plate 111 has a downwardly extending flange 114 along the circumferential direction. The space formed by the flange 114 and the lower end face of the cover plate 111 is used to accommodate the upper end of the pressure plate 2. This design allows the space formed by the flange 114 and the lower end face of the cover plate 111 to just cover the upper end of the pressure plate 2, preventing the rubber plug 1 with a buckle from falling off the pressure plate 2.

[0042] Preferred, such as Figure 1 As shown, the two buckles 112 are arranged opposite each other on the two sides of the flange 114. This design makes the structure of the rubber plug 1 with buckles more compact.

[0043] Preferred, such as Figures 1-4 As shown, the upper and lower surfaces of the cover plate 111 have the same outline shape, which makes it easier to manufacture the cover plate 111.

[0044] Preferred, such as Figure 1 as well as Figures 8-10As shown, the rubber stopper 12 has a blind hole 121 along the axial direction, and the opening of the blind hole 121 faces the upper end face of the cover plate 111. The blind hole 121 on the rubber stopper 12 can reduce the thickness of the rubber stopper 12 in the axial position, thereby facilitating the passage of the inflation needle through the axial position of the rubber stopper 12 and the inflation needle to charge nitrogen into the compressor.

[0045] Preferred, such as Figure 10 and Figure 11 As shown, an annular protrusion 122 is provided on the side of the other end of the rubber stopper 12, and the protrusion 122 is perpendicular to the axial direction of the rubber stopper 12. The protrusion 122 on the other end of the rubber stopper 12 can be interference-fitted with the suction hole 21 on the pressure plate 2, thereby improving the sealing effect and preventing nitrogen leakage from the compressor.

[0046] Preferred, such as Figure 1 and Figure 6 As shown, one end of the rubber stopper 12 and the through hole 113 of the cover plate 111 are fused together to form an integral structure by heat fusion. This design can improve the firmness between the rubber stopper 12 and the cover plate 111. In other embodiments, one end of the rubber stopper 12 and the through hole 113 of the cover plate 111 can be connected in a detachable manner.

[0047] In summary, the rubber stopper 1 with a snap-fit ​​provided by this utility model has the following beneficial effects: 1. Easy installation and disassembly. When installing the rubber stopper 1 with clips, the operator only needs to press it into place; no other installation tools are required. When the rubber stopper 1 with clips is installed in place, the clip 112 will make a clicking sound, allowing the operator to determine whether the rubber stopper 1 with clips is installed correctly by touch and / or sound. The operator can also check the sides of the rubber stopper 1 with clips and the pressure plate 2 to confirm whether the clip 112 is engaged with the lower end face of the pressure plate 2. When it is necessary to disassemble the rubber stopper 1 with clips, since the body 11 of the rubber stopper 1 with clips has a certain degree of elasticity, the clip 112 can be directly pried off the pressure plate 2 to remove the rubber stopper 1 with clips.

[0048] 2. Not easy to fall off. Because the rubber stopper 1 with the buckle is fastened to the pressure plate 2 by the buckle 112, even if there is oil in the air hole 21 on the pressure plate 2, or if the rubber stopper 1 with the buckle is hit by the packaging material, the rubber stopper 1 with the buckle is not easy to fall off the pressure plate 2.

[0049] 3. Facilitates new product development. The pressure plate 2 has a high degree of standardization in the industry. When developing new products in the future, only the rubber stopper 12 needs to be updated, while the plastic body 11 can be used interchangeably.

[0050] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the present utility model.
