Description

Technical Field

[0001] This application relates to the field of fluid control and sealing technology, and in particular to a stainless steel water level nut. Background Technology

[0002] Stainless steel water level nuts are commonly used in water conservancy projects, shipbuilding, chemical equipment and water treatment systems. Their core function is to fix water level sensors or seal and regulate valves through threaded connections. They need to withstand water flow impact, corrosive media and pressure changes for a long time.

[0003] In existing technologies, when fixing a faucet, there is a flow of water inside the faucet during use. Prolonged water flow can cause leakage at the connection point, wasting water resources. If the homeowner is away from home for an extended period, the leaking water may cause irreversible damage to the house and also affect downstairs residents. Utility Model Content

[0004] This application provides a stainless steel water level nut, which can improve the technical problem in related technologies where water flow inside the faucet during use can cause leakage at the interface due to prolonged water flow.

[0005] This application provides a stainless steel water level nut, including a nut body, a connecting hole inside the nut body, a threaded groove at one end of the connecting hole, an annular groove at the end of the connecting hole away from the threaded groove, and an anti-leakage component inside the annular groove.

[0006] The leak-proof component includes a support ring, one end of which is fixedly connected to the annular groove. A connecting block is fixedly connected to the end of the support ring near 13, and the connecting blocks are arranged in a ring array about the support ring. A rotating groove is formed at the end of the connecting block away from the support ring. A rotating block is rotatably connected inside the rotating groove. An arc-shaped extrusion strip is slidably connected to the end of the rotating block away from the rotating groove, and the extrusion strip is arranged in a ring array about the support ring. A sealing strip is fixedly connected to the extrusion strip.

[0007] By adopting the above technical solution, when connecting the faucet interface, after the faucet interface is inserted into the nut, the thread groove inside the nut engages with the thread of the faucet interface when the nut is rotated. The nut is rotated to connect, and after the nut is rotated to a certain position, the rotating block rotates inside the rotating groove. The other end of the rotating block pushes the extrusion strip to move inward. At the same time, the moving strip drives the sealing strip to seal the interface between the faucet and the pipe fitting, preventing leakage.

[0008] Optionally, each of the support rings is fixedly connected to a guide post between adjacent connecting blocks, each guide post is slidably connected to a sliding ring, each sliding ring is fixedly connected to a connecting plate on one side, and a pushing ring is fixedly connected between the connecting plates. The pushing ring is coaxial with the support ring, and the upper end of the pushing ring is slidably connected to the extrusion strip, with the sliding direction being radially arranged along the pushing ring.

[0009] By adopting the above technical solution, after the faucet interface reaches the designated position, the nut is rotated and continues to move inward. The faucet interface presses the push ring, and the push ring drives the extrusion strip to move inward as it moves downward.

[0010] Optionally, a movable block is fixedly connected to the bottom of the extrusion strip. The movable block is T-shaped. The push ring has a first sliding groove, and the movable block is slidably connected to the first sliding groove. The movable block and the first sliding groove are arranged in a ring array about the push ring.

[0011] By adopting the above technical solution, when the moving block, which is smaller at the top and larger at the bottom, slides inside the first sliding groove, the bottom of the extrusion strip and the top of the push ring are always kept in contact. When the push ring moves downward, it can drive the extrusion strip to move downward. At the same time, due to the rotating block connected to the outside of the extrusion strip, when the extrusion strip moves downward, the rotating block rotates, causing the extrusion strip to move inward through the first sliding groove and contract, thereby driving multiple sealing strips to seal the faucet interface.

[0012] Optionally, a second sliding groove is provided on the outer side of the extrusion strip, and a sliding block is slidably connected inside the second sliding groove. The end of the sliding block away from the second sliding groove is fixedly connected to the rotating block.

[0013] By adopting the above technical solution, in order to prevent the extrusion strip from changing with the angle of the rotating block when the rotating block rotates, the sliding block at one end of the rotating block slides inside the second sliding groove on the outside of the extrusion strip. When the angle of the rotating block is adjusted, it will not affect the extrusion strip sliding above the push ring.

[0014] Optionally, an elastic element is provided on the outer side of the guide post, one end of the elastic element abuts against the sliding ring, and the other end of the elastic element away from the sliding ring abuts against the support ring.

[0015] By adopting the above technical solution, during disassembly, reversing the nut removes the force on the push ring from the faucet interface. After the push ring is freed from the force, the sliding ring on the outside of the push ring returns to its original position under the elastic force of the elastic element, making it convenient for reuse.

[0016] Optionally, the extrusion strip, the moving block, and the pushing ring are all made of brass, and the sealing strip is made of rubber.

[0017] By adopting the above technical solution, brass material is moved inside the rubber material, which can effectively seal the faucet interface without affecting the movement.

[0018] Optionally, the outer side of the nut body may have anti-slip grooves.

[0019] By adopting the above technical solution, an anti-slip groove is opened on the outside of the nut body. The anti-slip groove can increase the surface roughness of the nut, increase the friction between the nut and tools such as wrenches and screwdrivers or fingers, so that operators can tighten or loosen the nut more easily and stably, reduce slippage, and improve work efficiency.

[0020] This utility model application has at least the following effects:

[0021] When connecting the faucet, after the faucet is inserted into the nut, the threaded groove inside the nut engages with the threaded faucet thread when the nut is turned. The nut is then rotated to connect the faucet. After the nut is rotated to a certain position, the rotating block rotates inside the rotating groove. The other end of the rotating block pushes the extrusion strip inward, which in turn moves the sealing strip to seal the faucet and pipe joint to prevent leakage. Attached Figure Description

[0029] The following combination Figures 1-4 This utility model is described in further detail.

[0030] This embodiment discloses a stainless steel water level nut: including a nut body 1, a connecting hole 12 is provided inside the nut body 1, a threaded groove 13 is provided at one end of the connecting hole 12, and an annular groove 14 is provided at the end of the connecting hole 12 away from the threaded groove 13, and an anti-leakage component 2 is provided inside the annular groove 14.

[0031] Please see Figures 2 to 4 The leak-proof component 2 includes a support ring 201. One end of the support ring 201 is fixedly connected to an annular groove 14. A connecting block 202 is fixedly connected to the end of the support ring 201 near 13, and the connecting blocks 202 are arranged in a ring array about the support ring 201. A rotating groove 215 is opened at the end of the connecting block 202 away from the support ring 201. A rotating block 209 is rotatably connected inside the rotating groove 215. An arc-shaped extrusion strip 211 is slidably connected to the end of the rotating block 209 away from the rotating groove 215, and the extrusion strip 211 is arranged in a ring array about the support ring 201. A sealing strip 213 is fixedly connected to the extrusion strip 211. A guide post 205 is fixedly connected between adjacent connecting blocks 202 of the support ring 201. A sliding ring 204 is slidably connected to each guide post 205. A connecting plate 206 is fixedly connected to one side of each sliding ring 204. A pushing ring 207 is fixedly connected between the connecting plates 206. The pushing ring 207 is coaxial with the support ring 201. The upper end of 207 is slidably connected to the extrusion strip 211, and the sliding direction is set radially along the push ring 207. The bottom of the extrusion strip 211 is fixedly connected to a moving block 214, which is "T" shaped. The push ring 207 has a first sliding groove 208, and the moving block 214 is slidably connected to the first sliding groove 208. The moving block 214 and the first sliding groove 208 are arranged in a ring array about the push ring 207. The outer side of the extrusion strip 211 has a second sliding groove 212, and a sliding block 210 is slidably connected inside the second sliding groove 212. The end of the sliding block 210 away from the second sliding groove 212 is fixedly connected to the rotating block 209. An elastic element 203 is provided on the outer side of the guide post 205. One end of the elastic element 203 abuts against the sliding ring 204, and the end of the elastic element 203 away from the sliding ring 204 abuts against the support ring 201. The extrusion strip 211, the moving block 214, and the push ring 207 are all made of brass, and the sealing strip 213 is made of rubber.

[0032] With this configuration, when connecting the faucet interface, after the faucet interface extends into the nut, the threaded groove 13 inside the nut engages with the threads of the faucet interface when the nut is rotated. The nut is rotated to connect, and after it reaches a certain position, further rotation causes the nut to move inward. The faucet interface presses against the push ring 207, which, as it moves downward, drives the pressing strip 211 inward. The sliding block 214, which is smaller at the top and larger at the bottom, slides inside the first sliding groove 208, ensuring that the bottom of the pressing strip 211 remains in contact with the top of the push ring 207. As the push ring 207 moves downward, it drives the pressing strip 211 downward. Simultaneously, due to the rotating block 209 connected to the outside of the pressing strip 211, the pressing strip 211 moves downward... When rotating, the rotating block 209 rotates, causing the moving part to retract inward through the first sliding groove 208, which drives multiple sealing strips 213 to seal the faucet interface. When the rotating block 209 rotates, in order to prevent the squeezing strip 211 from changing with the angle of the rotating block 209, the sliding block 210 at one end of the rotating block 209 slides inside the second sliding groove 212 outside the squeezing strip 211. When the angle of the rotating block 209 is adjusted, it will not affect the squeezing strip 211 sliding above the push ring 207. When disassembling, the reverse nut removes the force on the push ring 207 from the faucet interface. After the push ring 207 is removed from the force, the sliding ring 204 outside the push ring 207 returns to its original position under the elastic force of the elastic element 203, which is convenient for reuse.

[0033] Please see Figures 1 to 2 The outer side of the nut body 1 has anti-slip grooves 11.

[0034] This design, by creating an anti-slip groove 11 on the outer side of the nut body 1, increases the surface roughness of the nut, thereby increasing the friction between the nut and tools such as wrenches and screwdrivers or fingers. This allows operators to tighten or loosen the nut more easily and stably, reducing slippage and improving work efficiency.

[0035] The implementation principle of a stainless steel water level nut in this embodiment is as follows: When connecting to a faucet interface, after the faucet interface extends into the nut, the threaded groove 13 inside the nut engages with the thread of the faucet interface when the nut is rotated. The nut is rotated to connect, and after the nut has rotated to a certain position, the nut continues to rotate, moving inward. The faucet interface presses against the push ring 207. As the push ring 207 moves downward, it drives the pressing strip 211 to move inward. When the upper-smaller, lower-larger sliding block 214 slides inside the first sliding groove 208, the bottom of the pressing strip 211 remains in contact with the top of the push ring 207. In the mating state, when the pushing ring 207 moves downward, it can drive the extrusion strip 211 to move downward. At the same time, due to the rotating block 209 connected to the outside of the extrusion strip 211, when the extrusion strip 211 moves downward, the rotating block 209 rotates, causing the movement to retract inward through the first sliding groove 208, which drives multiple sealing strips 213 to seal the faucet interface. When disassembling, the reverse nut removes the force on the pushing ring 207 from the faucet interface. After the pushing ring 207 is freed from the force, the sliding ring 204 on the outside of the pushing ring 207 returns to its original position under the elastic force of the elastic element 203, which is convenient for secondary use.

[0036] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
