Description

Technical Field

[0001] The utility model belongs to the technical field of gas pipeline connection, and more specifically relates to a gas tank stove which can prevent a gas pipe from falling off. Background Art

[0002] Commonly used gas pipes are usually rubber pipes, polyethylene pipes, or stainless steel bellows. They connect the gas tank and the stove through the gas pipe to supply combustion gas to the stove. Since rubber pipes or polyethylene pipes are usually fixed with pipe clamps to fix the two ends of the gas pipe to the gas tank output end and the stove input end respectively, rubber pipes and polyethylene pipes age seriously after long-term use. Therefore, most users now use stainless steel bellows. The two ends of the stainless steel bellows are fixed with nuts by welding. The nuts connect the gas tank and the stove through the nuts. However, when the nuts are connected, they can loosen due to collisions or long-term vibration. In severe cases, they can even fall off, causing gas leaks and safety accidents. Therefore, there is an urgent need for a gas tank stove that prevents the gas pipe from falling off to solve the above problems. Utility Model Content

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a gas tank stove that prevents the gas pipe from falling off, which has the advantages of firmly installing the gas pipe and preventing the gas pipe from falling off.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] A gas tank stove for preventing a gas pipe from falling off comprises a stove and a first joint mounted on the stove, and further comprises a second joint mounted on the first joint, wherein the first joint is mounted on the stove by a threaded connection, and the second joint is mounted on the first joint by a plug-in connection, a stainless steel bellows is connected to an end of the second joint away from the first joint, and a first sealing ring and a second sealing ring are respectively mounted in the first joint and the second joint;

[0006] An anti-slip assembly is symmetrically installed on the outer wall of the first joint, and the anti-slip assembly includes a rectangular block installed on the outer wall of the first joint, a chamber is opened in the rectangular block, and a rotating hole and two rope passing holes are respectively opened on the side walls of the chamber, and the rotating hole and the rope passing holes both pass through the outer wall of the rectangular block, and a rotating rod is rotatably installed in the rotating hole, and handles are installed at both ends of the rotating rod, and a steel wire rope is installed in the rope passing hole, and both ends of the steel wire rope are inserted into the chamber and fixed on the rotating rod, and the anti-slip assembly also includes a hanging block installed on the second joint for hanging the steel wire rope, and a fixing assembly for fixing the rotating rod is installed on the rotating rod.

[0007] The advantages of this solution are at least that: when connecting the first joint and the second joint, the second joint is first plugged into the first joint, and sealing is achieved through the first sealing ring and the second sealing ring, and then the wire rope is hung on the hanging block, and the handle is turned, and the handle drives the rotating rod to rotate in the rotating hole, and the rotating rod drives the wire rope fixed on it to move into the chamber through the rope threading hole and wind around the rotating rod, and the rotating rod is fixed by the fixing component to prevent the rotating rod from rotating, thereby firmly fixing the first joint and the second joint together, and the anti-falling component is provided to avoid the phenomenon of gas pipe falling off in the prior art.

[0008] The utility model is further configured as follows: the fixing assembly includes a plurality of fixing holes opened on the rotating rod and a limiting hole opened on the outer wall of the first joint. The fixing holes penetrate the outer wall of the rotating rod, and at least four are provided and are arranged around the outer wall of the rotating rod. The limiting columns are slidably inserted into the fixing holes and the limiting holes.

[0009] The advantage of this solution is at least that when fixing the rotating rod, it is only necessary to rotate the fixing hole and the limiting hole to be coaxial, insert the limiting column into the fixing hole first, and then insert it into the limiting hole to complete the fixing of the rotating rod.

[0011] The advantages of this solution are at least that: the spring has a certain elasticity, and when subjected to an external force, it will undergo elastic deformation, and will return to its original shape after the external force is removed. When the wire rope is suspended in the U-shaped groove of the suspension block, it is first released from the inclined surface and squeezes the protrusion, so that the protrusion moves into the rectangular groove and fixes the wire rope in the U-shaped groove, thereby preventing the wire rope from falling off after being suspended on the suspension block.

[0012] The utility model is further configured as follows: magnet blocks with opposite magnetic properties are respectively provided on the sides of the protrusions that are close to each other.

[0013] The advantage of this solution is at least that: the attraction between oppositely charged magnets is utilized to move the protrusions closer to each other, thereby reducing the distance between the protrusions and lowering the probability of the wire rope accidentally falling off the bottom of the U-shaped groove.

[0019] The utility model is further configured as follows: an inner hexagonal groove recessed inwards is provided at one end of the locking nut.

[0020] The advantage of this solution is at least that the locking nut can be adjusted with a hexagonal wrench to ensure that the locking nut connects the fixing nut to the first semi-cylinder and the second semi-cylinder, and it is also convenient for disassembly.

[0021] In summary, the present invention has at least the following advantages:

[0022] 1. By providing a first joint, a second joint and an anti-slip assembly, when connecting the first joint and the second joint, the second joint is first threadedly connected to the first joint, and a seal is achieved through the first sealing ring and the second sealing ring. Then, the wire rope is hung on the hanging block, and the handle is turned to drive the rotating rod to rotate in the rotating hole. The rotating rod drives the wire rope fixed thereon to move into the chamber through the rope threading hole and wind around the rotating rod. The rotating rod is fixed by the fixing assembly to prevent the rotating rod from rotating, thereby firmly fixing the first joint and the second joint together. The anti-slip assembly is provided to avoid the phenomenon of gas pipe falling off in the prior art.

[0023] 2. By setting the U-shaped groove, rectangular groove, convex block and spring, the spring has a certain elasticity. When subjected to external force, it will elastically deform and return to its original shape after the external force is removed. When the wire rope is hung in the U-shaped groove of the suspension block, it first releases from the inclined surface and squeezes the convex block, so that the convex block moves into the rectangular groove and fixes the wire rope in the U-shaped groove, thereby preventing the wire rope from falling off after being hung on the suspension block.

[0024] 3. By setting a first semi-cylinder, a second semi-cylinder and a fixing nut, the first semi-cylinder and the second semi-cylinder are matched to form a whole cylinder, and then the fixing nut is threadedly connected to the cylinder, thereby increasing the connection between the first joint and the second joint, and preventing the first joint and the second joint from falling off; by setting a first threaded hole, a second threaded hole and a locking nut, the locking nut is threadedly connected in the first threaded hole and the second threaded hole, and the locking nut limits the fixing nut, thereby preventing the fixing nut from loosening due to long-term vibration.
