[0002] A gas cylinder (liquefied petroleum gas cylinder) is a steel cylinder used to store gas. Its wall thickness is approximately 2.5 mm, and its internal pressure is 0.5 to 1.2 MPa. Its safe service life is 15 years, requiring regular inspections every four years. In the past, placement in different ground environments could lead to unstable placement and the risk of tipping over. To address this, we propose a new LPG cylinder housing. Utility Model Content

[0003] The main purpose of the utility model is to provide a liquefied petroleum gas cylinder shell to solve the problems raised in the relevant background technology.

[0005] Furthermore, the telescopic support rod includes a threaded sleeve and a threaded rod, the threaded rod is screwed inside the threaded sleeve, and the length of the telescopic support rod is controlled by rotating the threaded rod.

[0006] Furthermore, a magnetic block is placed inside the polygonal groove, and a magnetic block is also inlaid on the polygonal protrusion. When the retractable support rod is placed in an open position, the magnetic block is used to strengthen and fix the polygonal protrusion, so that it can be stably placed in the polygonal groove, so that the retractable support rod does not move left and right.

[0007] Furthermore, the sleeve can slide left and right along the circular cross bar and can rotate freely, and when rotating, it drives the telescopic support rod to rotate together.

[0008] Furthermore, foot spikes are spirally installed at the bottom of the threaded rod to enhance stability, and can be replaced with metal foot spikes or rubber foot spikes according to different ground conditions.

[0009] Furthermore, when the tank body and the base are welded, a double-layer gas shielded welding process of carbon dioxide welding for bottoming and covering should be adopted to prevent the tank body and the base from rusting.

[0010] Furthermore, a threaded hole is provided at the top of the side wall of the threaded sleeve, and the polygonal convex block is provided with a threaded protrusion at the rear, for being screwed on the top of the side wall of the threaded sleeve.

[0011] Compared with the existing technology, the utility model has the following beneficial effects: the utility model improves the vertical placement stability and firmness of the tank body by arranging a retractable support rod on the tank body, and polygonal protrusions are installed on the side walls of the retractable support rod, which match the polygonal grooves opened on the side walls of the tank body, thereby achieving the purpose of fixing the support rod when stored, and when the support rod is in an open state, the opening angle can be fixed to prevent the support rod from swinging at an angle.

[0016] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0017] See also Figure 1-Figure 3 As shown, the purpose of this embodiment is to provide a liquefied petroleum gas cylinder housing, including a handle 1, a tank body 2, a base 3 and a valve 4. A strip groove 21 is provided on the side wall of the tank body 2, and a circular cross bar 22 is fixedly installed at the top position inside the strip groove 21. A sleeve 51 is rotatably installed on the circular cross bar 22. A telescopic support rod 5 is fixedly installed on the side wall of the sleeve 51, and a polygonal protrusion 54 is spirally installed on the top of the side wall of the telescopic support rod 5. A polygonal groove 23 is provided on the side wall of the strip groove 21 for correspondingly engaging the polygonal protrusion 54.

[0018] It should be noted that the shapes of the polygonal protrusion 54 and the polygonal groove 23 match each other, and both are designed as regular polygons.

[0019] The telescopic support rod 5 includes a threaded sleeve 52 and a threaded rod 53 . The threaded rod 53 is screwed inside the threaded sleeve 52 . The length of the telescopic support rod 5 is controlled by rotating the threaded rod 53 .

[0020] A magnetic block is placed inside the polygonal groove 23, and a magnetic block is also inlaid on the polygonal protrusion 54. When the telescopic support rod 5 is opened and placed, the magnetic block is used to strengthen and fix the polygonal protrusion 54, so that it can be stably placed in the polygonal groove 23, so that the telescopic support rod 5 does not move left and right.

[0021] The sleeve 51 can slide left and right along the circular cross bar 22 and can rotate freely, and when rotating, the telescopic support rod 5 is driven to rotate together.

[0022] A foot spike is screwed onto the bottom of the threaded rod 53 to enhance the stability of the contact with the ground in the unfolded state.

[0023] A threaded hole is provided at the top of the side wall of the threaded sleeve 52 , and a threaded protrusion is provided at the rear of the polygonal protrusion 54 for being screwed onto the top of the side wall of the threaded sleeve 52 .

[0024] Operation method: First, weld the tank body 2 and the base 3, then weld the handle 1 to the top of the tank body 2, install the valve 4 to the opening at the top of the tank body 2, and then put the sleeve 51 on the circular cross bar 22, weld the threaded sleeve 52 to the side wall of the sleeve 51, and the threaded rod 53 is screwed into the threaded sleeve 52. The foot nail is screwed into the bottom position of the threaded rod. A threaded hole is provided at the top position of the side wall of the threaded sleeve 52, and the polygonal protrusion 54 is rear-set with a threaded protrusion so that the polygonal protrusion 54 is screwed into the top position of the side wall of the threaded sleeve 52. When storing, first rotate the threaded rod 53 to retract it into the threaded sleeve 52, so that the retractable support rod 5 can be stored in the strip groove 21, and then the sleeve 51 is driven to move by moving the retractable support rod 5, so that the polygonal protrusion 54 is clamped in the polygonal groove 22, and the fixing effect is strengthened by the magnetic suction block built into the polygonal groove 22 and the polygonal protrusion 54 to ensure the stability of the retractable support rod 5 in the stored state;

[0025] When the tank body 2 needs to be used, the telescopic support rod 5 is first moved to make the polygonal protrusion 54 move out of the polygonal groove 22, and then the threaded rod 53 is rotated to make it extend from the threaded sleeve 52, and the telescopic support rod 5 is fully unfolded. Then, after the telescopic support rod 5 is rotated to a fixed angle, the telescopic support rod 5 is moved again, and the polygonal protrusion 54 is returned to the polygonal groove 22. Since the polygonal groove 22 and the polygonal protrusion 54 are both regular polygons, the clamping connection between the two after rotating at different angles can achieve the limiting and fixing effect of the telescopic support rod 5. By rotating the threaded rod 53, the foot nail is in contact with the ground and has a supporting effect. Since the telescopic support rod 5 is a threaded sleeve structure, the support rod will not shrink, so the supporting effect is very good.

[0026] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
