Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tabletop stoves, in particular to a gas pipeline for tabletop stoves. Background Art
[0002] Gas pipeline is a special pipeline for transporting combustible gas. It is a metal gas pipe hose that replaces the traditional clip-on rubber hose. It can solve the defects of rubber hoses that are easy to fall off, easy to age, easy to be bitten by insects, and have a short service life. The gas pipeline has the characteristics of easy installation, reliable connection, corrosion resistance, no gas blockage, good flexibility, long service life, and can be bent arbitrarily without deformation and no gas blocking. The surface soft protective layer material is safer, easier to clean, and beautiful. The service life of the stainless steel threaded metal hose is 8 years. The PE gas pipe adopts the stainless steel threaded connection method. Although it makes its installation and disassembly more convenient, it is not stable when it vibrates and slides relative to each other, and then gas leakage occurs. In addition, if the corresponding gas control valve is not closed during installation and maintenance, the gas is very likely to leak, thereby endangering the life safety of the staff. For this reason, we propose a tabletop stove gas pipeline. Utility Model Content

[0010] Optionally, a fixing plate is fixed to the outer side of the gas pipeline, and a first spring is fixed to one side of the fixing plate, and one end of the first spring is fixed to the other side of the limiting ring plate.
[0011] The utility model has the following beneficial effects:
[0012] 1. The tabletop stove gas pipeline passes through the locking column on the locking plate and is locked therewith, and then under the push of the limiting ring plate, the positioning column and the mounting ring plate are plugged together to limit the position of the mounting ring plate. Then, under the action of the moving external force, the mounting ring plate is locked by the locking column and the limiting ring plate, and the mounting ring plate is not easy to be separated from the locking column, so that the locking column locks the connecting pipe more firmly, thereby making the connection between the gas pipelines more firmly.
[0013] 2. The gas pipeline of the tabletop stove passes through the locking column through the locking plate and then turns to the mounting ring plate. At this time, the limiting ring plate is loosened so that the positioning column can be plugged into the mounting ring plate, thereby quickly completing the connection between the gas pipeline and the connecting pipeline, making it more convenient to disassemble and install, thereby making the installation or maintenance of the tabletop stove more convenient.
[0014] 3. The gas pipeline for the tabletop stove, through the action of the elastic force of the second spring, enables the stop valve of the gas pipeline and the connecting pipeline to close the gas pipeline and the connecting pipeline respectively when the gas pipeline and the connecting pipeline are not installed, and when the gas pipeline and the connecting pipeline are installed, the stop valves are in contact with each other, and then under the relative action of each other, the stop valves can be opened, and then the gas pipeline and the connecting pipeline are connected, so that during maintenance, the gas pipeline and the connecting pipeline can be closed in time, which can effectively avoid gas leakage, thereby protecting the personal safety of the staff.

DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] See also Figures 1 to 6A gas pipeline for a tabletop stove comprises a gas pipeline 1, a connecting pipeline 2 is connected to one end of the gas pipeline 1, a cross bracket 8 is fixed inside the gas pipeline 1 and the connecting pipeline 2, and a stop valve 9 which can axially move and close the gas pipeline 1 and the connecting pipeline 2 is movably connected to the cross bracket 8, and the cross bracket 8 can limit the movement trajectory of the stop valve 9. When the gas pipeline 1 and the connecting pipeline 2 are not yet connected, the stop valve 9 can close the gas pipeline 1 and the connecting pipeline 2 to avoid gas leakage, thereby making the installation safer. When the gas pipeline 1 and the connecting pipeline 2 are installed, the stop valve 9 is opened to connect the gas pipeline 1 and the connecting pipeline 2. A second spring 10 with a reset function is sleeved on the stop valve 9. Under the action of the elastic force of the second spring 10, the stop valve 9 can return to its original position to close the gas pipeline 1 and the connecting pipeline 2. In addition, a locking column 7 which is plugged into the outer side of the connecting pipe 2 is movably connected to the gas pipeline 1. Under the limitation of the gas pipeline 1, the locking column 7 can stably move along a fixed trajectory. Under the plugging action of the locking column 7, the position between the gas pipeline 1 and the connecting pipe 2 can be limited, so that the gas pipelines 1 can be stably connected to each other. In addition, a movable mounting ring plate 4 is sleeved on the gas pipeline 1, and the mounting ring plate 4 can be snapped into the locking column 7. Under the limitation of the mounting ring plate 4, the locking column 7 can maintain a state of being plugged into the connecting pipe 2, thereby making the connection more secure. At the same time, a limiting ring plate 5 which limits the position of the mounting ring plate 4 is movably connected to the gas pipeline 1. The limiting ring plate 5 limits the position of the mounting ring plate 4 to prevent the mounting ring plate 4 from rotating easily, thereby making the mounting ring plate 4 stably in a fixed position.
[0024] See also Figures 1 to 3 One end of the second spring 10 is fixed to the cross bracket 8, and the other end of the second spring 10 is fixed to the stop valve 9. Under the action of the elastic force of the second spring 10, the stop valve 9 can move.
[0025] See also Figures 1 to 5 A pushing plate 11 is fixed in the middle of the outer side of the locking column 7, and a third spring 12 is fixed to one side of the pushing plate 11. The third spring 12 is fixed to the gas pipeline 1, and the pushing plate 11 is movably connected to the gas pipeline 1, which further determines the movement trajectory of the locking column 7, thereby making the movement of the locking column 7 more stable, and under the action of the elastic force of the third spring 12, the locking column 7 can be smoothly separated from the plug-in relationship with the connecting pipe 2, thereby making its disassembly more convenient.
[0026] See also Figures 1 to 6An L-shaped locking plate 13 is fixed on the mounting ring plate 4, one end of the locking plate 13 passes through the locking column 7 and is engaged with the locking column 7. After passing through the locking column 7, the locking plate 13 rotates, and the locking plate 13 can be engaged with the locking column 7, thereby making the connection between the mounting ring plate 4 and the locking column 7 more stable.
[0027] See also Figures 1 to 6 One end of the locking column 7 extends out of the gas pipeline 1 and its top end is round. One end of the locking column 7 abuts against the inner side of the mounting ring plate 4, and the inner side of the mounting ring plate 4 is an arc-shaped groove inclined outward. When the mounting ring plate 4 moves, one end of the locking column 7 can move relatively. After it moves into the arc-shaped groove, the locking column 7 can be disconnected from the connecting pipe 2.
[0028] See also Figures 1 to 6 A protruding structure is designed on the inner side of the limiting ring plate 5, and the protruding structure is movably connected to the outer side of the gas pipeline 1. The moving trajectory of the limiting ring plate 5 can be limited by the protruding structure, and a positioning column 14 is fixed on one side of the limiting ring plate 5. The positioning column 14 is plugged into the mounting ring plate 4. Under the pushing action of the limiting ring plate 5, the positioning column 14 can be plugged into the mounting ring plate 4, thereby limiting the mounting ring plate 4 and preventing the mounting ring plate 4 from rotating easily.
[0029] See also Figures 1 to 6 A fixing plate 3 is fixed to the outside of the gas pipeline 1, and a first spring 6 is fixed to one side of the fixing plate 3. One end of the first spring 6 is fixed to the other side of the limiting ring plate 5. Under the action of the elastic force of the first spring 6, the limiting ring plate 5 can smoothly drive the positioning column 14 to move.
[0030] In summary, when the tabletop stove gas pipeline is used, the mounting ring plate 4 is pulled to compress the first spring 6, and then one end of the connecting pipe 2 is inserted into the interior of the gas pipeline 1. At this time, the two stop valves 9 are in contact and push each other to move relative to each other, so that they can open the gas pipeline 1 and the connecting pipe 2, so that the gas pipeline 1 and the connecting pipe 2 can be connected, and then the mounting ring plate 4 is pushed to move the mounting ring plate 4, and then the locking column 7 is pushed to move, and the locking plate 13 passes through the locking column 7, and then the mounting ring plate 4 is rotated so that the locking plate 13 is engaged with the locking column 7. At this time, under the action of the elastic force of the first spring 6, the limiting ring plate 5 can push the positioning column 14 to move, and then the positioning column 14 can be plugged into the mounting ring plate 4, and the position of the mounting ring plate 4 is limited, so that the connection is more secure.
