Abstract
Description
Technical Field
[0001] This utility model relates to a connecting hose, specifically, to a gas connecting hose that is easy to install. Background Technology
[0002] Gas fuel is a general term for gaseous fuels that can burn and release heat for use by residents and industrial enterprises. There are many types of gas, mainly including natural gas, manufactured gas, liquefied petroleum gas, biogas, and coal gas. With the rapid development of society, the popularity of gas has also increased rapidly. In the process of gas transmission, gas hoses are the most commonly used gas pipes to deliver gas to households. Existing gas hoses are usually connected by threaded connections. A rubber sealing ring is installed at the hose joint to seal the gap at the connection. Due to the long-term compression of the sealing ring by the hose joint during use, the compressed sealing ring is difficult to recover. Especially when the gas hose shakes, the hose joint causes uneven compression on the sealing ring, making the surface of the sealing ring uneven. This reduces the contact effect between the sealing ring and the hose joint, and consequently reduces the sealing effect of the sealing ring at the hose joint. In view of this, we propose a gas connection hose that is easy to install. Utility Model Content
[0003] The purpose of this invention is to provide a gas connection hose that is easy to install, in order to solve the problem mentioned in the background art where the sealing effect of the sealing ring is reduced due to compression.
[0004] To address the aforementioned problems, the present invention aims to provide a conveniently installed gas connection hose, comprising a first hose and a second hose. A first connector and a second connector are fixedly connected to the ends of the first hose and the second hose respectively, close to each other. A connecting mechanism is provided on the first connector near the second connector, and a sealing mechanism is provided on the second connector near the first connector. When the first connector and the second connector are connected, the sealing mechanism seals the connection point. The sealing mechanism includes a sealing ring. A compression ring is slidably fitted on the second connector, located on the side of the sealing ring away from the first connector. The inner wall of the compression ring near the sealing ring is inclined. The connecting mechanism drives the compression ring to move towards the sealing ring. The inclined surface of the moving compression ring contacts the side of the sealing ring away from the second connector. During the movement, the compression ring compresses the sealing ring, ensuring tight contact between it and the connection point of the first connector and the second connector.
[0005] As a further improvement to this technical solution, the sealing mechanism also includes a mounting ring fixedly connected to the second connector near the position of the first connector. The mounting ring has a movable groove on the side near the connector. The compression ring and the sealing ring are located inside the movable groove, and a gap is left between the sealing ring and the inner wall of the movable groove.
[0006] As a further improvement to this technical solution, the connecting mechanism includes a movable component, and a collar is provided on the side of the movable component away from the second connector. The collar is slidably sleeved on the first connector, and the movable component drives the collar to move away from the second connector.
[0007] As a further improvement to this technical solution, the movable component includes a fixed ring fixedly connected to the first connector near the second connector. The fixed ring is located inside the collar. A compression spring is fixedly connected between the side of the fixed ring away from the second connector and the inner wall of the collar. When the compression spring is in a compressed state, the compression spring relaxes and drives the collar to move away from the second connector.
[0008] As a further improvement to this technical solution, a number of L-shaped rotating plates are rotatably connected to the side of the collar near the second connector. The collar drives the L-shaped rotating plates to move during the movement. The L-shaped rotating plates include a horizontal section and a vertical section. A top block is fixedly connected to the side of the vertical section near the extrusion ring.
[0009] As a further improvement to this technical solution, the mounting ring is provided with several through holes on the side near the top block. The through holes correspond to the position and number of the top block. During the movement of the L-shaped rotating plate, the top block is moved so that one end of it passes through the through hole and moves the extrusion ring.
[0010] As a further improvement to this technical solution, two annular grooves are formed on the first and second connectors at positions close to each other. When the first and second connectors are connected together, the two annular grooves form a sealing groove, with one side of the sealing ring located inside the sealing groove.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. This easy-to-install gas hose connection involves the operator threading two hoses together, then pushing the moving component closer to the sealing mechanism. The operator then flips the L-shaped rotating plate, causing the top block to move closer to the sealing mechanism. Subsequently, the moving component moves the L-shaped rotating plate and the top block, causing the compression ring to move. The moving compression ring compresses the sealing ring, ensuring that the sealing ring is always in close contact with the connection between the two hose joints. This improves the sealing effect of the sealing ring on the gas hose and reduces the probability of the sealing effect decreasing due to deformation of the sealing ring. Attached Figure Description

[0026] 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. Example 1
[0027] Please see Figure 1 - Figure 5As shown, the purpose of this embodiment is to provide a convenient gas connection hose, including a first hose 1 and a second hose 2. The first hose 1 and the second hose 2 are respectively fixedly connected to a first connector 11 and a second connector 21 at their respective close ends. A groove is formed on the inner wall of the first connector 11 near the second connector 21. A sealing ring is provided inside the groove. The sealing ring matches the cross-sectional shape of the groove. A convex tube is fixedly connected to the end of the second connector 21 near the first connector 11. The convex tube matches the cross-sectional shape of the groove. Threads are provided on the outer wall of the convex tube and the inner wall of the groove. When the convex tube is threaded into the groove, the convex tube connects the first connector 11 and the second connector 21 together. The convex tube presses the sealing ring against the inner wall of the groove. The sealing ring seals the gap between the convex tube and the inner wall of the groove. Two annular grooves are formed on the first connector 11 and the second connector 21 at their respective close ends. When the first connector 11 and the second connector 21 are connected together, the two annular grooves form a sealing groove.
[0028] A connecting mechanism 3 is provided on the first connector 11 near the second connector 21, and a sealing mechanism 4 is provided on the second connector 21 near the first connector 11. When the first connector 11 and the second connector 21 are connected together, the sealing mechanism 4 seals the connection between the first connector 11 and the second connector 21. The connection between the first connector 11 and the second connector 21 is further reinforced by the connecting mechanism 3 and the sealing mechanism 4, reducing the probability of rotation of the first connector 11 and the second connector 21, improving the sealing effect of the sealing ring between the convex tube and the groove, and enabling the connecting mechanism 3 to work with the sealing mechanism 4 to effectively seal the connection between the first connector 11 and the second connector 21.
[0029] refer to Figure 5 and Figure 6 The sealing mechanism 4 includes a sealing ring 43, which is embedded in the sealing groove. The sealing groove restricts the side wall of the sealing ring 43, making the sealing ring 43 in close contact with the inner wall of the sealing groove. A compression ring 42 is slidably sleeved on the second connector 21. The compression ring 42 is located on the side of the sealing ring 43 away from the first connector 11. The inner wall of the compression ring 42 is inclined on the side close to the sealing ring 43. The connecting mechanism 3 drives the compression ring 42 to move towards the sealing ring 43. The inclined surface of the moving compression ring 42 contacts the side of the sealing ring 43 away from the second connector 21. During the movement, the compression ring 42 compresses the sealing ring 43, making it in close contact with the connection between the first connector 11 and the second connector 21. The compressed sealing ring 43 seals the sealing groove. At the same time, under the restriction of the sealing groove, the side of the sealing ring 43 located inside the sealing groove will not move, thereby preventing the sealing ring 43 from being misaligned with the connection between the first connector 11 and the second connector 21 and affecting the sealing effect of the sealing ring 43, thus ensuring the sealing effect of the sealing ring 43 on the sealing groove.
[0030] The sealing mechanism 4 also includes a mounting ring 41 fixedly connected to the second connector 21 near the first connector 11. The mounting ring 41 has a movable groove on the side near the first connector 11. The compression ring 42 and the sealing ring 43 are located inside the movable groove. The mounting ring 41 covers the compression ring 42 and the sealing ring 43. A gap is left between the sealing ring 43 and the inner wall of the movable groove, so that when the compression ring 42 moves, the inclined surface of the compression ring 42 can move into the gap between the sealing ring 43 and the inner wall of the movable groove, so that the inclined surface of the compression ring 42 can compress the sealing ring 43. During the process of the compression ring 42 compressing the sealing ring 43, the sealing ring 43 deforms towards the position where the second connector 21 and the first connector 11 are connected. The sealing ring 43 deforms towards the connection due to compression, thereby filling the gap and achieving a seal, so that the sealing ring 43 can seal the position where the second connector 21 and the first connector 11 are connected.
[0031] refer to Figure 5 , Figure 7 and Figure 8 The connecting mechanism 3 includes a moving component. A collar 33 is provided on the side of the moving component away from the second connector 21. The collar 33 is slidably fitted onto the first connector 11. The moving component drives the collar 33 to move away from the second connector 21. Several L-shaped rotating plates 34 are rotatably connected to the side of the collar 33 closest to the second connector 21. During the movement of the collar 33, the L-shaped rotating plates 34 move. The L-shaped rotating plates 34 include a horizontal section and a vertical section. A top block 35 is fixedly connected to the side of the vertical section closest to the compression ring 42. Several through holes 44 are provided on the side of the mounting ring 41 closest to the top block 35, and the positions and number of the through holes 44 and the top block 35 are... Correspondingly, after the first connector 11 and the second connector 21 are connected, the worker pushes the collar 33 to move closer to the second connector 21. Then, the worker flips the L-shaped rotating plate 34 so that it drives the top block 35 to rotate closer to the second connector 21. When the L-shaped rotating plate 34 contacts the side wall of the mounting ring 41, it remains stationary. At this time, the top block 35 corresponds to the position of the through hole 44. During the movement, the L-shaped rotating plate 34 drives the top block 35 to move so that one end passes through the through hole 44 and drives the compression ring 42 to move. When the compression ring 42 moves closer to the first connector 11, the compression ring 42 compresses the sealing ring 43 to seal the sealing groove.
[0032] The movable component includes a fixed ring 31 fixedly connected to the first connector 11 near the second connector 21. The fixed ring 31 is located inside the collar 33. A compression spring 32 is fixedly connected between the side of the fixed ring 31 away from the second connector 21 and the inner wall of the collar 33. When the compression spring 32 is in a compressed state, the compression spring 32 relaxes and drives the collar 33 to move away from the second connector 21. When the collar 33 moves towards the second connector 21, the moving collar 33 compresses the compression spring 32. At this time, the compression spring 32 relaxes and drives the collar 33 to move away from the second connector 21, so that the moving collar 33 drives the extrusion ring 42 to move through the L-shaped rotating plate 34 and the top block 35 to extrude the sealing ring 43.
[0033] It should be emphasized that the spring force of the compression spring 32 should be selected to ensure that the spring force of the compression spring 32 is sufficient to push the compression ring 42 through the top block 35, so that the compression ring 42 can compress the sealing ring 43.
[0034] When using this device:
[0035] The workers placed the compression ring 42 and the sealing ring 43 into the inside of the mounting ring 41 in sequence, so that the compression ring 42 and the sealing ring 43 were located outside the second connector 21. Then the workers threaded the first connector 11 and the second connector 21 together. At this time, the sealing ring 43 was located inside the sealing groove.
[0036] Then, the staff pushes the collar 33 to move the L-shaped rotating plate 34 towards the direction of the second connector 21. The staff flips the L-shaped rotating plate 34 to move the top block 35. When the L-shaped rotating plate 34 comes into contact with the outside of the mounting ring 41, it stops rotating. At this time, the staff rotates the collar 33 to rotate the L-shaped rotating plate 34 and the top block 35, so that the top block 35 rotates to the position corresponding to the through hole 44. The compression spring 32, which is in a compressed state, relaxes and drives the collar 33, the L-shaped rotating plate 34 and the top block 35 to move.
[0037] The moving top block 35 drives the compression ring 42 to move so that its inclined surface contacts the sealing ring 43. During the movement, the compression ring 42 compresses the sealing ring 43 so that it is in close contact with the inner wall of the sealing groove, thereby improving the sealing effect of the sealing ring 43 at the connection between the first joint 11 and the second joint 21.
