Description

Technical Field

[0001] The utility model relates to the technical field of skeleton glue seals, in particular to a skeleton glue seal with good sealing performance. Background Art

[0002] The skeleton rubber seal is a kind of seal, usually composed of rubber material and metal frame. Its main function is to seal and prevent dust in mechanical equipment. Through the elasticity of rubber and the support of metal frame, the skeleton rubber seal can effectively prevent liquid, gas, dust and other substances from penetrating into the interior of mechanical equipment, thereby protecting the normal operation of the equipment.

[0003] In the process of using the skeleton seal, when sealing the parts, the seal and the parts are not in good contact, which will affect the sealing effect. Therefore, it is necessary to improve it. Utility Model Content

[0004] The utility model aims to provide a skeleton rubber seal with good sealing performance, which solves the problem that the sealing effect is affected by the insufficient fit between the sealing member and the parts.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a skeleton rubber seal with good sealing performance, comprising an inner ring, the outer side of the inner ring is slidably sleeved with a skeleton, the outer side of the skeleton is slidably sleeved with an outer ring, the outer ring and the inner ring are both made of rubber, the inner side of the outer ring is slidably sleeved with two symmetrically distributed connecting rings, the outer surface of the connecting ring is fixedly connected with a plurality of annular and evenly distributed protrusions, the inner side of the connecting ring is fixedly connected with a plurality of annular and evenly distributed first clamping blocks, the first clamping blocks are clamped with the outer ring, the outer side of the inner ring is fixedly connected with four annular and evenly distributed second clamping blocks, the second clamping blocks are clamped with the skeleton, and a supporting mechanism is provided on the skeleton.

[0006] Preferably, the connecting ring and the protrusion are an integrated structure, and both the connecting ring and the protrusion are made of soft rubber. By designing the connecting ring and the protrusion, the connection fit of the sealing member can be improved.

[0007] Preferably, the outer ring is provided with a plurality of first card slots in annular shape and evenly distributed, and a first card block is clamped inside each of the first card slots. The connection ring can be fixed by designing the clamping connection between the first card slots and the first card block.

[0008] Preferably, four annular and evenly distributed second card slots are provided inside the frame, and second card blocks are clamped inside the second card slots. The inner ring can be fixed by designing the clamping connection between the second card blocks and the second card slots.

[0009] Preferably, the support mechanism includes a slide groove, a plurality of slide grooves are provided inside the frame, a slide rod is slidably sleeved inside each slide groove, a top block is fixedly connected to one end of two adjacent slide rods away from the slide groove, the top block is slidably connected to the frame, the top block is slidably connected to the outer ring, and a spring is provided inside the frame. By designing the support mechanism, the outer ring can be internally supported.

[0010] Preferably, one end of the spring is fixedly connected to the top block, and the other end of the spring is fixedly connected to the frame. The spring is designed so that the force of the spring can act on the top block.

[0011] Preferably, a groove is provided inside the outer ring, and a top block is slidably connected inside the groove. The groove is designed so that the top block can slide into the groove of the outer ring.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model designs the function of the top block. When the outer ring is sleeved on the outside of the frame, the outer ring will squeeze the top block, allowing the top block to slide toward the inside of the frame. The top block will squeeze the spring. After the outer ring is completely sleeved on the outside of the frame, the elasticity of the spring will give the top block an outward thrust, which can support the outer ring. When the outer ring is connected to the parts, the outer ring and the parts can be more closely fitted and the sealing can be better.

[0014] 2. The utility model designs the function of the connecting ring and the protrusion. When the parts are sealed through the outer ring, the connecting ring and the protrusion are softer than the outer ring. When the outer ring is sealed, the deformation of the connecting ring and the protrusion is larger, which can make the connecting ring and the protrusion fit the parts more closely, and can further improve the sealing effect. In addition, the outer ring and the inner ring can be detached from the frame, which is convenient for replacing aging parts. BRIEF DESCRIPTION OF THE DRAWINGS

By designing the connecting ring 4 and the protrusions 5, the connection fit of the seal can be improved.

The inner part of the outer ring 3 is provided with a plurality of first clamping grooves 7 in annular shape and evenly distributed, and the inner part of each first clamping groove 7 is clamped with a first clamping block 6. By designing the clamping connection between the first clamping groove 7 and the first clamping block 6, the connecting ring 4 can be fixed. The outer side of the inner ring 1 is fixedly connected with four second clamping blocks 8 in annular shape and evenly distributed, and the second clamping blocks 8 are clamped with the skeleton 2. The inner part of the skeleton 2 is provided with four second clamping grooves 10 in annular shape and evenly distributed, and the inner part of the second clamping groove 10 is clamped with a second clamping block 8. By designing the clamping connection between the second clamping block 8 and the second clamping groove 10, the inner ring 1 can be fixed. A supporting mechanism 9 is provided on the skeleton 2.

[0023] See also Figure 1 , Figure 3 , Figure 4The support mechanism 9 includes a slide groove 91. A plurality of slide grooves 91 are provided inside the skeleton 2. A slide rod 92 is slidably sleeved inside each slide groove 91. A top block 93 is fixedly connected to one end of two adjacent slide rods 92 away from the slide groove 91. The top block 93 is slidably connected to the skeleton 2. The top block 93 is slidably connected to the outer ring 3. A groove 95 is provided inside the outer ring 3. The top block 93 is slidably connected inside the groove 95. By designing the groove 95, the top block 93 can slide into the groove 95 of the outer ring 3.

[0024] The specific implementation process of the utility model is as follows: when in use, through the action of the top block 93, when the outer ring 3 is sleeved on the outside of the skeleton 2, the outer ring 3 will squeeze the top block 93, so that the top block 93 can slide toward the inside of the skeleton 2, and the top block 93 will squeeze the spring 94. After the outer ring 3 is completely sleeved on the outside of the skeleton 2, under the elastic action of the spring 94, a thrust outward will be given to the top block 93, which can play a supporting role for the outer ring 3.

At the same time, through the clamping of the first clamping block 6 and the second clamping block 8, the inner ring 1 and the connecting ring 4 can be connected to the skeleton 2 respectively. The clamping method makes it easy to disassemble the inner ring 1 and the outer ring 3, and it is convenient to replace the aged parts.
