Description

Technical Field

[0001] This utility model relates to the field of stove connecting pipe technology, and more specifically, to a stove socket-type connecting pipe joint anti-detachment device. Background Technology

[0002] Gas connections for residential gas stoves come in two types: threaded and socketed. To prevent accidental gas leaks caused by rodents gnawing through the hoses or sharp objects damaging them, it is recommended that users replace the hoses with stainless steel corrugated hoses.

[0003] However, for stoves with socket-type interfaces, stainless steel corrugated pipes are prone to detachment when installed. This forces gas companies to advise users to continue using rubber hoses when encountering such stove interfaces, or to replace the stove with a threaded gas interface, causing considerable inconvenience to users. Currently, socket-type interfaces mainly rely on O-rings to tighten onto the stove connection. During installation, the stove connection must be free of oil and the installer must tighten the nuts appropriately; otherwise, the rubber ring may deform and leak gas.

[0004] Currently, during the use of socket-type corrugated pipes connected to stove connecting pipes, the connection between the corrugated pipe and the stove connecting pipe may fall off due to stove cleaning or movement, resulting in insufficient connection between the socket-type corrugated pipe and the stove connecting pipe, which affects the use of the socket-type corrugated pipe. Therefore, a stove socket-type connecting pipe joint anti-detachment device is proposed. Utility Model Content

[0005] In order to overcome the problems and defects in the prior art, this utility model provides a stove socket-type connecting pipe joint anti-detachment device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stove socket-type connecting pipe joint anti-detachment device, including a fixing ring, and an adjustment anti-detachment mechanism is provided on the outside of the fixing ring;

[0007] The adjustable anti-fall-off mechanism includes two first threaded holes, which are respectively opened on the top and bottom surfaces of the fixing ring. A threaded rod is threadedly connected inside the first threaded hole. A lifting plate is provided at the top of the threaded rod. An installation bearing is installed between the threaded rod and the lifting plate. A fixed connecting plate is installed at the top of the lifting plate. A connecting ring is fixedly connected to one side of the fixed connecting plate. The number of fixed connecting plates and connecting rings is set to two. A first circular retaining ring is installed inside one of the connecting rings, and a second circular retaining ring is installed inside the other connecting ring. A disassembly and assembly mechanism is provided between the fixed connecting plate and the lifting plate.

[0008] Preferably, the disassembly and assembly mechanism includes a connecting screw, which is fixed to the top of the lifting plate, and a second threaded hole is provided on the top surface of the fixed connecting plate.

[0009] Preferably, a fixing nut is sleeved on the outside of the connecting screw, and both the fixing nut and the second threaded hole are threadedly connected to the connecting screw.

[0010] Preferably, the top of the threaded rod passes through the fixing ring and extends to the outside of the fixing ring, and a fixing knob is fixedly connected to the bottom of the threaded rod.

[0011] Preferably, the diameter of the first circular retaining ring is smaller than the diameter of the second circular retaining ring, and both the first and second circular retaining rings are made of high-strength spring steel.

[0012] Preferably, the mounting bearing is a sealed bearing, and the connecting ring and the fixed connecting plate are connected by welding.

[0013] Preferably, the outer sides of the first and second circular retaining rings are provided with a wear-resistant coating, which is made of tungsten carbide.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. By setting an adjustable anti-detachment mechanism, rotating the fixing knob causes the threaded rod to rotate and move inside the first threaded hole, thereby driving the lifting plate to move. This allows the first and second circular ring springs to be adjusted and moved, so that the first circular ring spring can be engaged with the bellows nut and the second circular ring spring can be engaged with the stove connection pipe, preventing the bellows from falling off the stove connection pipe. Compared with the existing technology, this solves the problem of the bellows being installed on the socket-type stove and the concern that it might fall off during use. By pulling apart the first and second circular ring springs, they can be quickly engaged with the bellows nut and the stove interface, effectively preventing the socket-type connection pipe joint from falling off and improving the safety efficiency of the anti-detachment device. At the same time, the first and second circular ring springs have a certain deformation capacity, which can better adapt to interfaces of different sizes, improving the applicability of the device.

[0016] 2. By setting up a disassembly and assembly mechanism, it is easy to quickly disassemble and replace the fixed connecting plate, the first circular ring spring, and the second circular ring spring, avoiding the situation where the entire anti-detachment device needs to be replaced due to the damage of a single spring. This facilitates the maintenance and replacement of the device. The wear-resistant coating on the outside of the first and second circular ring springs is made of tungsten carbide, which greatly improves the wear resistance of the springs and extends the service life of the device.

A threaded rod 3 is threadedly connected inside the first threaded hole 2. A lifting plate 4 is provided on the top of the threaded rod 3. A mounting bearing 5 is installed between the threaded rod 3 and the lifting plate 4. A fixed connecting plate 6 is installed on the top of the lifting plate 4. A connecting ring 7 is fixedly connected to one side of the fixed connecting plate 6. The number of fixed connecting plates 6 and connecting rings 7 is set to two. A first circular ring retaining spring 8 is installed inside one connecting ring 7, and a second circular ring retaining spring 9 is installed inside the other connecting ring 7. A disassembly and assembly mechanism is provided between the fixed connecting plate 6 and the lifting plate 4.

[0026] As attached Figure 1 , 2As shown in Figures 4 and 5, the disassembly and assembly mechanism includes a connecting screw 10, which is fixed to the top of the lifting plate 4. A second threaded hole 11 is provided on the top surface of the fixed connecting plate 6. A fixing nut 12 is sleeved on the outside of the connecting screw 10. The fixing nut 12 and the second threaded hole 11 are both threadedly connected to the connecting screw 10, which facilitates the disassembly and replacement of the first circular ring spring 8 and the second circular ring spring 9.

[0027] As attached Figure 1 , 2 As shown in Figure 5, the top of the threaded rod 3 passes through the fixing ring 1 and extends to the outside of the fixing ring 1. The bottom of the threaded rod 3 is fixedly connected to a fixing knob 13, which facilitates the rotation of the threaded rod 3 by the fixing knob 13.

[0028] As attached Figure 1 , 2 As shown in Figures 4 and 5, the diameter of the first circular snap ring 8 is smaller than the diameter of the second circular snap ring 9, and both the first circular snap ring 8 and the second circular snap ring 9 are made of high-strength spring steel to ensure the service life of the first circular snap ring 8 and the second circular snap ring 9, and to facilitate the connection of the first circular snap ring 8 and the second circular snap ring 9 to the corrugated pipe nut and the stove connecting pipe, respectively.

[0029] As attached Figure 1 , 2 As shown in Figure 5, the bearing 5 is a sealed bearing to improve the bearing service life.

[0031] The working principle of this utility model is as follows: During use, the anti-detachment device for a socket-type connecting pipe joint of a stove provided by this utility model first installs the socket-type stainless steel corrugated pipe on the stove before preventing detachment, and tightens the corrugated pipe joint nut to connect the corrugated pipe to the stove pipe. One end of the anti-detachment device, namely the larger diameter second circular ring spring 9, is then secured to the stainless steel nut of the corrugated pipe. Rotating the fixing knob 13 drives the threaded rod 3 to rotate. Simultaneously, due to the threaded connection between the threaded rod 3 and the first threaded hole 2, the threaded rod 3 moves inside the first threaded hole 2. The screw rod 3 rotates while the lifting plate 4 is mounted with a bearing 5. The screw rod 3 rotates to move the lifting plate 4 up and down, thereby lengthening or shortening the distance between the first circular ring spring 8 and the second circular ring spring 9 to accommodate different stove interface connection lengths. The other end of the first circular ring spring 8 with a smaller diameter is clamped onto the stove body interface. The fixing knob 13 is rotated again to tighten the telescopic rod, completing the entire installation. The anti-detachment device is clamped between the stainless steel nut and the stove gas interface by the first circular ring spring 8 and the second circular ring spring 9, effectively preventing the socket-type connecting pipe joint from falling off.
