Description

Technical Field

[0001] This utility model relates to the field of sealing ring installation technology, and more specifically, to a pre-installed sealing ring docking installation structure. Background Technology

[0002] Pre-installed sealing ring butt joint installation structures ensure sealing performance and prevent leakage: These structures guarantee a tight connection, effectively preventing liquids, gases, or solid particles from leaking from the joint. This is crucial for maintaining the normal operation of equipment or systems.

[0003] Among existing publicly available documents, patent publication number CN217441012U discloses a sealing structure for a water pipe connector. This technology involves installing a layer of PTFE tape on the inner wall of both the top and bottom sealing rings, with rubber water-blocking strips installed on both sides of the PTFE tape layer. Combined with top and bottom air cushions installed at both ends of the inner walls of the top and bottom sealing rings, this increases the material composition for sealing gaps between pipes, ensuring a good sealing effect during use. However, this technology still has the following drawbacks.

[0004] In the pre-sealing process, the pre-sealed ring butt installation structure mainly relies on the sealing rings to be butt-fitted at the designated sealing position. However, it is difficult to achieve the inner and outer sealing rings to be embedded and butt-fitted during the sealing process, resulting in poor sealing firmness. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides the following technical solution: a pre-set sealing ring docking installation structure, including a sealing connecting pipe and a sealing outer ring, wherein the sealing outer ring is fixed to the outer wall of the sealing connecting pipe, and the outer wall of the sealing outer ring is provided with inner and outer embedded sealing components; the inner and outer embedded sealing components include two linkage rings slidably disposed on the outer wall of the sealing outer ring, each linkage ring having an embedded ring fixedly connected to its inner wall, the embedded rings being inserted into the sealing outer ring, and a threaded sleeve being installed at one end of the sealing outer ring; the threaded sleeve being threadedly connected to the sealing connecting pipe, a linkage bar being installed on one side of the linkage ring, both linkage rings being fixedly connected to the linkage bar, a socket block being fixedly installed on one side of the linkage bar, and a screw being threadedly connected to the inner wall of the socket block.

[0006] Preferably, the outer sealing ring is slidably connected to the outer wall of the sealing coupling tube, and the vertical cross-sectional shape of both linkage rings is arc-shaped. Both the linkage ring and the embedded ring are made of stainless steel. A support frame is slidably connected to the outer wall of the sleeve block, and both support frames are fixedly connected to the sealing coupling tube. A rotating cap is fixedly installed at one end of the screw. A support ring is fixedly installed at the other end of the outer sealing ring, and the support ring is fixedly connected to the sealing coupling tube. A support sleeve is provided on one side of the support ring, and the support sleeve is fixedly connected to the sealing coupling tube. A sealing inner ring is fixedly connected to one end of the sealing coupling tube, and a compression support cylinder is provided on one side of the sealing inner ring, and the compression support cylinder is fixedly connected to the threaded sleeve.

[0007] When this technology is used, the sealing coupling pipe drives the support ring to move, the sealing outer ring is pressed against the threaded sleeve, the screw drives the sleeve block to move to the right under the action of the thread transmission force, the sleeve block drives the linkage bar to move to the right, the linkage bar drives the two linkage rings to move to the right synchronously, the embedding ring drives the sealing outer ring to embed and move to the right to press against the threaded sleeve, thereby achieving synchronous embedding and sealing of the inner and outer rings through the sealing inner ring and sealing outer ring.

[0008] Preferably, the outer wall of the threaded sleeve is provided with two sets of guide assemblies; each guide assembly includes a support block fixedly disposed on the outer wall of the threaded sleeve, and a reinforcing block is fixedly installed on the upper surface of the support block. An inclined strip is fixedly installed on one side of the reinforcing block, and a guide strip is fixedly connected to the top end of the inclined strip. The guide strip is slidably connected to the linkage ring. The outer wall of the guide strip is a smooth surface, and both the reinforcing block and the inclined strip are used to support the guide strip.

[0009] When this technology is in use, as the linkage ring moves to the right, the threaded sleeve simultaneously supports two support blocks, the reinforcing block supports the inclined bar, and the guide bar guides the outer wall of the linkage ring to slide, enabling the linkage ring to achieve stable guided sliding.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] 1. This utility model adopts an internal and external embedded sealing assembly. The sealing coupling tube drives the support ring to move, the support ring drives the sealing outer ring to move, the sealing outer ring is pressed against the threaded sleeve, the screw drives the sleeve block to move to the right under the action of the thread transmission force, the embedded ring drives the sealing outer ring to embed and move to the right and press against the threaded sleeve. Through the sealing inner ring and sealing outer ring, the internal and external synchronous embedding and sealing are achieved, the sealing is more firm and the sealing firmness is better.

[0012] 2. This utility model adopts a guide component, in which the linkage ring slides along the outer wall of the guide strip. The inclined strip supports the guide strip, and the guide strip guides the linkage ring to slide along the outer wall. In this way, the linkage ring can achieve stable sliding, avoid the linkage ring from shaking, and improve the sealing stability. Attached Figure Description

[0019] 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.

[0020] As attached Figure 1 -Appendix Figure 5 The diagram shows a pre-set sealing ring docking installation structure, which is provided with inner and outer embedded sealing components. The inner and outer embedded sealing components can drive the outer sealing ring 2 to be embedded and squeezed onto the threaded sleeve 5 through the embedded ring 4. The inner sealing ring 13 and the outer sealing ring 2 achieve synchronous inner and outer embedding and sealing, resulting in a more secure and stronger seal. The specific structural settings of the inner and outer embedded sealing components are as follows.

[0021] In this technical solution, as shown in the appendix Figure 1 -Appendix Figure 3As shown, the sealing outer ring 2 is fixed to the outer wall of the sealing coupling pipe 1. The outer wall of the sealing outer ring 2 is provided with inner and outer embedded sealing components. The inner and outer embedded sealing components include two linkage rings 3 that are slidably disposed on the outer wall of the sealing outer ring 2. Each linkage ring 3 has an embedded ring 4 fixedly connected to its inner wall. The embedded ring 4 is inserted into the sealing outer ring 2. A threaded sleeve 5 is installed at one end of the sealing outer ring 2. The threaded sleeve 5 is threadedly connected to the sealing coupling pipe 1. A linkage bar 6 is installed on one side of the linkage ring 3. Both linkage rings 3 are fixedly connected to the linkage bar 6. A sleeve block 7 is fixedly installed on one side of the linkage bar 6. A screw 8 is threadedly connected to the inner wall of the sleeve block 7.

[0022] In this technical solution, as shown in the appendix Figure 1 -Appendix Figure 3 As shown, a support frame 9 is slidably connected to the outer wall of the sleeve block 7, and both support frames 9 are fixedly connected to the sealing coupling tube 1. A rotating cap 10 is fixedly installed at one end of the screw 8 to facilitate the rotation of the two rotating caps 10, which in turn drive the two screws 8 to rotate, thus realizing the rotation operation of the screws 8. A support ring 11 is fixedly installed at the other end of the sealing outer ring 2, and the support ring 11 is fixedly connected to the sealing coupling tube 1. A support sleeve 12 is provided on one side of the support ring 11, and the support sleeve 12 is fixedly connected to the sealing coupling tube 1, so that the sealing coupling tube 1 can drive the support ring 11 to move, and the support ring 11 can drive the sealing outer ring 2 to move. By rotating the support sleeve 12, the support sleeve 12 drives the sealing coupling tube 1 to rotate. One end of the sealing connector 1 is fixedly connected to a sealing inner ring 13. A compression support cylinder 14 is provided on one side of the sealing inner ring 13, and the compression support cylinder 14 is fixedly connected to the threaded sleeve 5 so that the sealing inner ring 13 can compress the compression support cylinder 14. The compression support cylinder 14 and the sealing connector 1 are sealed through the sealing inner ring 13.

[0023] When this technical solution is used, by rotating the support sleeve 12, the support sleeve 12 drives the sealing coupling tube 1 to rotate. Under the action of the thread meshing force, the sealing coupling tube 1 and the threaded sleeve 5 cause the sealing coupling tube 1 to squeeze the sealing inner ring 13. The sealing inner ring 13 squeezes the support cylinder 14. The squeezed support cylinder 14 and the sealing coupling tube 1 are sealed through the sealing inner ring 13. The sealing coupling tube 1 drives the support ring 11 to move. The support ring 11 drives the sealing outer ring 2 to move. The sealing outer ring 2 is squeezed on the threaded sleeve 5. At the same time, the two rotating caps 10 are rotated. The two rotating caps 10 drive the two screws 8 to rotate. The screws 8 drive the sleeve block 7 to move to the right under the action of the thread transmission force. The sleeve block 7 moves to the right along the inner wall of the support frame 9. The sleeve block 7 drives the linkage bar 6 to move to the right. The linkage bar 6 drives the two linkage rings 3 to move to the right synchronously. The linkage rings 3 drive the embedded ring 4 to move to the right. The embedded ring 4 drives the sealing outer ring 2 to embed and move to the right, squeezing it on the threaded sleeve 5. Thus, the sealing inner ring 13 and the sealing outer ring 2 achieve synchronous embedding and sealing inside and outside.

[0024] In this technical solution, as shown in the appendix Figure 5 As shown, the outer wall of the threaded sleeve 5 is provided with two sets of guide assemblies; the guide assembly includes a support block 15 fixedly disposed on the outer wall of the threaded sleeve 5, and a reinforcing block 16 fixedly installed on the upper surface of the support block 15. An inclined strip 17 is fixedly installed on one side of the reinforcing block 16, and a guide strip 18 is fixedly connected to the top of the inclined strip 17. The guide strip 18 is slidably connected to the linkage ring 3. The outer wall of the guide strip 18 is a smooth surface, and both the reinforcing block 16 and the inclined strip 17 are used to support the guide strip 18.

[0025] When this technical solution is used, when the linkage ring 3 moves to the right, the linkage ring 3 will slide along the outer wall of the guide bar 18. At the same time, the threaded sleeve 5 supports two support blocks 15, the support blocks 15 support the reinforcing block 16, the reinforcing block 16 supports the inclined bar 17, and the inclined bar 17 supports the guide bar 18. The guide bar 18 guides the outer wall of the linkage ring 3 to slide, so that the linkage ring 3 can stably slide and avoid the linkage ring 3 from shaking.

[0026] 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.
