Description

Technical Field

[0001] This utility model relates to a gas corrugated hose, specifically a household gas stainless steel corrugated hose designed to prevent detachment. Background Technology

[0002] Household gas stainless steel corrugated hose is a type of pipe used to connect household gas pipelines to gas appliances (such as gas stoves, water heaters, etc.). It is made of 304 or 316L stainless steel and is made into a spiral corrugated structure through hydraulic process. The outer layer is covered with a PVC protective layer, which has the advantages of high temperature resistance, corrosion resistance, rodent resistance, and aging resistance.

[0003] Traditional stainless steel corrugated gas hoses are typically installed quickly by plugging them into connectors for ease of installation. This method can result in an unstable connection with the connector, making them prone to detachment. Furthermore, the stainless steel corrugated hose can easily come off when subjected to forceful pulling, posing a certain safety hazard. Summary of the Invention

[0004] The purpose of this utility model is to provide a household gas stainless steel corrugated hose that is designed to prevent detachment. By setting an anti-detachment mechanism, it prevents detachment and improves the stability after installation. This solves the problem that traditional gas stainless steel corrugated hoses are usually quickly installed with connectors by plugging them in, which can lead to an unstable connection and easy detachment.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a household gas stainless steel corrugated hose designed to prevent detachment, comprising a stainless steel corrugated hose, a connector at the top of the stainless steel corrugated hose, and an external hexagonal swivel ring rotatably connected to the end of the stainless steel corrugated hose, the external hexagonal swivel ring being threadedly assembled with the end of the connector; it also includes an anti-detachment mechanism, the anti-detachment mechanism being disposed at the end of the stainless steel corrugated hose, the anti-detachment mechanism comprising a fixing ring fixedly connected to the outside of the end of the stainless steel corrugated hose, a push-pull ring slidably connected to the outside of the fixing ring, a plurality of elastic clamping plates fixedly connected to the top of the push-pull ring, the top of the elastic clamping plates being provided with triangular protrusions, and elastic straps being sleeved on the outside of the elastic clamping plates, the elastic clamping plates being locked on the plane of the external hexagonal swivel ring after the push-pull ring slides upward, thus restricting the rotation of the external hexagonal swivel ring.

[0006] Furthermore, the outer ring of the push-pull ring is fixedly connected with several protrusions to facilitate push-pull operations.

[0007] Furthermore, the top and bottom of the fixed ring are provided with limiting rings to restrict the push-pull ring to the fixed ring.

[0008] Furthermore, the outer surface of the fixed ring is provided with a plurality of limiting protrusions, and the inner ring of the push-pull ring is provided with a plurality of limiting grooves. The limiting protrusions are slidably connected in the limiting grooves and are used to limit the rotation of the push-pull ring.

[0009] Furthermore, the inner ring of the external hexagonal swivel has an annular groove, which is rotatably connected to the convex ring. The inner ring of the convex ring is fixedly connected to the outer surface of the stainless steel corrugated hose, and the convex ring is used to restrict the external hexagonal swivel to the end of the stainless steel corrugated hose.

[0010] Furthermore, an inner convex ring is fixedly connected to the inner wall of the connector, and a sealing plug is provided at the bottom of the inner convex ring.

[0011] Furthermore, the bottom of the outer ring of the sealing plug is tapered, which is adapted to the inner side of the end of the stainless steel corrugated hose.

[0012] Furthermore, a sealing ring is fitted on the outer side of the end of the stainless steel corrugated hose, and the top of the sealing ring contacts the bottom of the connector.

[0013] The beneficial effects of this utility model are as follows:

[0014] (1) This utility model sets up an anti-dropping mechanism, specifically by connecting the end of the stainless steel corrugated hose to the end of the connector through an external hexagonal swivel and locking it with a wrench. Then, the push-pull ring is pushed upward by the protrusion, so that several elastic plates are engaged with the six planes on the outside of the external hexagonal swivel. The elastic strap will apply elastic force to the elastic plates to improve the fixing effect. This method can restrict the rotation of the external hexagonal swivel, thereby preventing the situation from falling off and improving the stability after installation.

[0015] (2) This utility model sets a sealing plug, specifically inserting the sealing plug into the inside of the connector and then putting the sealing ring on the end of the stainless steel corrugated hose. When the stainless steel corrugated hose and the connector are connected, the inner wall of the end of the stainless steel corrugated hose will be tightly attached to the conical surface on the sealing plug, thereby achieving a sealing effect. The sealing ring will be squeezed by the connector and the stainless steel corrugated hose, sealing the connection again. This method can achieve a good sealing effect and avoid leakage.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] 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.

[0026] Please see Figures 1-6A household gas stainless steel corrugated hose designed to prevent detachment includes a stainless steel corrugated hose 1, with a connector 11 at the top and an external hexagonal swivel ring 12 rotatably connected to the end. The external hexagonal swivel ring 12 is threadedly assembled with the end of the connector 11. It also includes an anti-detachment mechanism 2, located at the end of the stainless steel corrugated hose 1. The anti-detachment mechanism 2 includes a fixing ring 21 fixedly connected to the outer side of the end of the stainless steel corrugated hose 1, a push-pull ring 22 slidably connected to the outer side of the fixing ring 21, several elastic clamping plates 23 fixedly connected to the top of the push-pull ring 22, the top of the elastic clamping plates 23 having a triangular protrusion, several protrusions 221 fixedly connected to the outer ring of the push-pull ring 22, and an elastic strap 24 sleeved on the outer side of the elastic clamping plates 23. The end of the stainless steel corrugated hose 1 is connected to the end of the connector 11 via the external hexagonal swivel ring 12. The threads are connected and tightened with a wrench. Then, the push-pull ring 22 is pushed upward by the protrusion 221, so that several elastic plates 23 are engaged with the six planes on the outside of the external hexagonal swivel ring 12. The elastic strap 24 applies elastic force to the elastic plates 23 to improve the fixing effect. This method can restrict the rotation of the external hexagonal swivel ring 12, thereby preventing it from falling off and improving the stability after installation. The top and bottom of the fixing ring 21 are set with limit rings to restrict the push-pull ring 22 on the fixing ring 21. The external hexagonal swivel ring 12 is threadedly assembled with the end of the connector 11.

[0027] The inner ring of the external hexagonal swivel 12 has an annular groove, and a convex ring 121 is rotatably connected in the annular groove on the external hexagonal swivel 12. The inner ring of the convex ring 121 is fixedly connected to the outer surface of the stainless steel corrugated hose 1. The convex ring 121 is used to restrict the external hexagonal swivel 12 to the end of the stainless steel corrugated hose 1.

[0028] An inner convex ring 111 is fixedly connected to the inner wall of the connector 11. A sealing plug 112 is provided at the bottom of the inner convex ring 111. A sealing ring 13 is sleeved on the outer side of the end of the stainless steel corrugated hose 1. The bottom of the outer ring of the sealing plug 112 is set with a conical surface. The conical surface on the sealing plug 112 is adapted to the inner side of the end of the stainless steel corrugated hose 1. The top of the sealing ring 13 contacts the bottom of the connector 11. When the sealing plug 112 is inserted into the interior of the connector 11 and the sealing ring 13 is sleeved on the end of the stainless steel corrugated hose 1, the inner wall of the end of the stainless steel corrugated hose 1 will be tightly pressed against the conical surface on the sealing plug 112 when the stainless steel corrugated hose 1 and the connector 11 are connected, thereby achieving a sealing effect. The sealing ring 13 will be squeezed by the connector 11 and the stainless steel corrugated hose 1, sealing the connection again. This method can achieve a good sealing effect and avoid leakage.

[0029] The outer surface of the fixed ring 21 is fixedly connected with several limiting protrusions 211, and the inner ring of the push-pull ring 22 is provided with several limiting grooves 222. The limiting protrusions 211 are slidably connected in the limiting grooves 222 on the push-pull ring 22. The limiting protrusions 211 are used to restrict the rotation of the push-pull ring 22.

[0030] One specific application of this embodiment is:

[0031] In use, first insert the sealing plug 112 into the inside of the connector 11, then the inner convex ring 111 limits the sealing plug 112. Then, put the sealing ring 13 on the end of the stainless steel corrugated hose 1. When the stainless steel corrugated hose 1 and the connector 11 are installed, connect the end of the stainless steel corrugated hose 1 to the end of the connector 11 through the external hexagonal swivel 12 and tighten it with a wrench. At this time, the inner wall of the end of the stainless steel corrugated hose 1 will be tightly attached to the conical surface on the sealing plug 112, thereby achieving a sealing effect. The sealing ring 13 will be squeezed by the connector 11 and the stainless steel corrugated hose 1, sealing the connection again. This method can achieve a good sealing effect and avoid leakage. When the external hexagonal swivel 12 is threadedly connected and locked to the connector 11, the installation of the stainless steel corrugated hose 1 is completed. Since the push-pull ring 22 is located away from the external hexagonal swivel 12 during installation, and the elastic plate 23 is away from the external hexagonal swivel 12, it will not affect the rotation of the external hexagonal swivel 12.

[0032] After the external hexagonal ring 12 is locked, it is rotated to the position corresponding to the elastic retaining plate 23. Then, the push-pull ring 22 is pushed upward by the protrusion 221, causing several elastic retaining plates 23 to engage with the six planes on the outside of the external hexagonal ring 12. This moves the triangular protrusion at the top of the elastic retaining plate 23 to the top of the external hexagonal ring 12, thus locking and fixing the elastic retaining plate 23. The elastic strap 24 on the outside of the elastic retaining plate 23 applies elastic force to the elastic retaining plate 23, making the elastic retaining plate 23 fit tightly against the external hexagonal ring 12 and preventing... To prevent the push-pull ring 22 from falling off, and because the push-pull ring 22 slides on the limiting protrusion 211 through the limiting groove 222, the push-pull ring 22 is restricted from rotating. This method can restrict the outer hexagonal swivel ring 12, prevent the outer hexagonal swivel ring 12 from rotating, thereby preventing the outer hexagonal swivel ring 12 from falling off and improving the stability after installation. When it is necessary to disassemble the stainless steel corrugated hose 1, pull the push-pull ring 22 down forcefully to make the elastic plate 23 disengage from the outer hexagonal swivel ring 12. Finally, use a wrench to rotate the outer hexagonal swivel ring 12 counterclockwise to disassemble it.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that the above embodiments do not limit the scope of protection of this utility model in any way, and all technical solutions obtained by equivalent substitution or other means fall within the scope of protection of this utility model. Parts not covered by this utility model are the same as or can be implemented using existing technology.
