Abstract
Description
Technical Field
[0001] This utility model relates to a sealing structure, specifically a room temperature gas packing sealing structure. Background Technology
[0002] Traditional packing materials (such as packing) are prone to wear, aging, and loss of elasticity under the friction of the reciprocating motion of the shaft, resulting in a decrease in sealing effect and gas leakage.
[0003] When the packing needs to be tightened or replaced due to wear, it is often necessary to disassemble the entire equipment or sealing cavity, which is a complicated, time-consuming, and labor-intensive process that affects the continuous operation of the equipment.
[0004] After the packing is compressed, it will generate a large clamping force and frictional resistance on the shaft, which will not only increase the energy consumption of driving the shaft, but also accelerate the wear of the shaft and the packing itself. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a room temperature gas packing sealing structure to solve the problems existing in the background art.
[0006] The room temperature gas packing sealing structure of this utility model is achieved through the following technical solution, including a guide seat body and a packing structure disposed inside the guide seat body; The guide hole inside the guide seat body is provided with multiple fixed cavities, and the filler structure is placed in the fixed cavity; The guide seat body is also provided with an ejection structure, and the ejection end of the ejection structure is placed in the fixed cavity and corresponds to the position of the packing structure.
[0007] As a preferred technical solution, the packing structure includes an mounting ring and a sealing silicone ring; The mounting ring is placed inside the fixed cavity and corresponds to the position of the ejection end of the ejection structure; the sealing silicone ring is placed inside the mounting ring. A shaft is slidably disposed within the guide hole, and the shaft contacts the packing structure, thereby achieving a sealing effect.
[0008] As a preferred technical solution, both sides of the sealing silicone ring are inclined with chamfers to facilitate the guidance of the shaft during sliding and reduce the wear on the sealing silicone ring.
[0009] As a preferred technical solution, the ejection structure includes a clearance groove and an ejection block disposed on the fixed cavity; The ejector block is disposed in the clearance groove, and a push rod is provided at the rear end of the ejector block through the guide seat body; The ejector block contacts the mounting ring, and the ejector block is pushed by the push rod to compress and deform the mounting ring and the sealing silicone ring.
[0010] As a preferred technical solution, a connecting rod is fixed above the push rods to connect them.
[0011] As a preferred technical solution, the guide seat body is made of high-strength aluminum alloy. This material is lightweight, high-strength, and corrosion-resistant. It can reduce the weight of the entire sealing structure and ensure that it can be used for a long time in a normal temperature gas environment without being corroded, thus improving the reliability and durability of the structure.
[0012] As a preferred technical solution, the sealing silicone ring is made of wear-resistant silicone material, which can maintain good elasticity and sealing performance in a normal temperature gas environment, while resisting the friction and wear generated when the shaft slides, further improving the sealing effect and service life of the sealing structure.
[0013] The beneficial effects of this utility model are: This invention effectively ensures long-term sealing reliability in ambient gas environments by using a packing structure that is in close contact with the shaft and combining it with an adjustable ejection structure.
[0014] The sealing silicone ring of this invention has guide chamfers on both sides, which greatly reduces the frictional resistance and wear on the sealing ring when the shaft slides, thereby extending the service life of the overall sealing structure.
[0015] This invention, through its ejection structure, allows for convenient external clamping or adjustment of the packing material without disassembling the entire device, simplifying maintenance and improving work efficiency. Attached Figure Description

[0019] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.
[0020] like Figures 1-4 As shown, this utility model discloses a room-temperature gas packing sealing structure, including a guide seat body 1. A guide hole 5 is formed inside the guide seat body 1, which is used for the shaft 6 to pass through and slide. To achieve multi-stage sealing within the guide hole 5, multiple fixed cavities 2 are spaced apart along the axial direction of the guide hole 5. Each fixed cavity 2 is equipped with a packing structure 12, thereby creating a continuous sealing effect at different positions of the shaft 6.
[0021] The packing structure 12 consists of an mounting ring 3 and a sealing silicone ring 4. The mounting ring 3 is embedded inside the fixing cavity 2 and can be stably positioned in the guide seat body 1. The sealing silicone ring 4 is located inside the mounting ring 3 and is used to form a sealing contact with the outer wall of the shaft 6. The sealing silicone ring 4 is made of wear-resistant silicone material, which has good elasticity and durability and can maintain sealing performance for a long time in a normal temperature gas environment. In order to reduce the damage to the sealing silicone ring 4 when the shaft 6 is inserted or reciprocating, the sealing silicone ring 4 is designed with chamfers 7 on both sides. The chamfers 7 are arranged at an angle and can play an automatic guiding role when the shaft 6 passes through, effectively reducing frictional resistance and extending the service life of the sealing ring 4.
[0022] To facilitate adjustment and replacement of the packing structure 12, a push-out structure is provided on the guide seat body 1. The push-out structure includes a recessed groove 8, a push-out block 9, and a push rod 10. The recessed groove 8 is located on the side wall of the fixed cavity 2 to accommodate the push-out block 9. One end of the push-out block 9 abuts against the mounting ring 3, and the other end extends to the outside of the guide seat body 1 via the push rod 10. The operator can directly push or pull the push rod 10 from the outside, thereby moving the push-out block 9 within the recessed groove 8. When the push rod 10 pushes the push-out block 9, the push-out block 9 moves into the fixed cavity 2, pressing against the mounting ring 3 and causing radial deformation of the sealing silicone ring 4, thereby increasing the clamping force of the sealing ring 4 on the shaft 6 and improving the sealing effect. Conversely, when the push rod 10 retracts, the push-out block 9 releases pressure on the mounting ring 3, loosening the connection between the mounting ring 3 and the sealing ring 4, facilitating the disassembly or replacement of the packing structure 12.
[0023] A connecting rod 11 is also provided above the multiple push rods 10. The connecting rod 11 is used to link and fix adjacent push rods 10 together, ensuring that multiple push rods 10 can move synchronously during operation, avoiding uneven pressure on the mounting ring 3 caused by unilateral force. The setting of the connecting rod 11 can ensure that the sealing silicone ring 4 always remains coaxial with the shaft 6 during the tightening or loosening process, improving the sealing stability.
[0024] In practical applications, the shaft 6 slides along the guide hole 5 and passes sequentially through the packing structure 12 in multiple fixed cavities 2. At this time, the sealing silicone ring 4 is in close contact with the outer wall of the shaft 6, forming a circumferential sealing layer, effectively preventing leakage of room temperature gas. When the shaft 6 undergoes slight displacement or reciprocating motion, the sealing silicone ring 4 can adaptively compensate due to its elasticity, thereby maintaining good sealing performance. At the same time, the presence of the chamfer 7 greatly reduces friction, reducing energy consumption and wear.
[0025] Furthermore, the guide seat body 1 is made of high-strength aluminum alloy, which not only has the characteristics of being lightweight and high-strength, but also effectively resists corrosion, improving the reliability and service life of the entire structure in a normal temperature gas environment. The sealing silicone ring 4 is made of wear-resistant silicone material, which, while ensuring good elasticity, has excellent anti-friction properties, effectively delaying the wear caused by long-term sliding of the shaft 6.
[0026] This invention allows for easy adjustment or replacement of the sealing ring 4 through the cooperation of the push rod 10 and the push-out block 9 without disassembling the entire device, greatly improving the convenience and efficiency of use and maintenance. Compared with the traditional method that relies on overall disassembly, the room temperature gas packing sealing structure of this invention has significant advantages in terms of structural reliability, ease of maintenance, and service life.
[0027] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
