Description

Technical Field

[0001] The utility model relates to the technical field of industrial oxygen tanks, in particular to a leakage-proof industrial oxygen tank. Background Art

[0002] Industrial oxygen tanks are mainly used to collect and store oxygen. When the oxygen needs to be released later, the gas nozzle on the surface of the oxygen tank needs to be used in conjunction with the connecting pipe. The surface of the gas nozzle usually has a valve to keep it sealed.

[0003] For example, an industrial oxygen tank body with an anti-leakage function, whose application number is CN202022169142.4 and whose authorization announcement date is 20210601, comprises a gas tank body, a gas nozzle, a sealing rubber sleeve and a bottom plate, wherein a bottom plate is arranged below the gas tank body, and a gas nozzle is threadedly installed at the top end of the gas tank body, and a sealing rubber sleeve is fixedly installed inside the gas tank body, and an extension block is fixedly installed on the left and right sides of the lower end of the gas tank body, and a through hole is provided inside the extension block, and a lap plate is fixedly connected above the bottom plate, a fixed rod is arranged inside the through hole, and a shock absorbing spring is fixedly installed below the fixed rod, and a buffer spring is fixedly installed above the fixed rod, and a groove and a movable groove are provided on the rear side of the bottom plate, and a first compression spring is fixedly installed inside the groove, and a clamping rod is fixedly provided above the first compression spring. The industrial oxygen tank body with an anti-leakage function can overlap multiple gas tank bodies when moving, which can ensure the sealing of the device and improve the vibration reduction effect at the same time.

[0004] In the workshop, the oxygen tank is easily scratched, causing it to fall, and the valve on the gas nozzle is easily rotated due to the impact, causing oxygen leakage when the gas nozzle is opened. Therefore, it is urgent to design a leak-proof industrial oxygen tank to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a leak-proof industrial oxygen tank to solve the above-mentioned deficiencies in the prior art.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A leak-proof industrial oxygen tank comprises a base assembly, wherein the base assembly is internally threadedly connected to a tank assembly, the tank assembly comprises a tank body, a valve component is arranged at the top of the tank body, the valve component comprises a threaded seat, a mounting cylinder is installed at the center of the top of the threaded seat by bolts, a threaded rod is internally threadedly connected to the mounting cylinder, and a handle is installed at the top of the threaded rod by bolts, a mounting seat is welded to the bottom end of the threaded rod, and a spring is rotatably connected to the bottom end of the mounting seat, a piston is installed at the bottom end of the spring by bolts, and three sealing rings are sleeved on the outside of the piston, and a mounting tube is integrally formed on the outer wall of one side of the mounting cylinder.

[0008] Furthermore, a panel is welded on the top of the tank body, and the valve member is located inside the panel.

[0009] Furthermore, a through hole is opened on the outer wall of one side of the enclosure, and the mounting tube is coaxial with the through hole.

[0010] Furthermore, the base assembly includes a base, and a threaded groove is formed on the outer wall of the top of the base.

[0011] Furthermore, a placement groove is provided on an outer wall of one side of the base, and a ball is provided inside the placement groove.

[0012] Furthermore, a threaded portion is provided at the bottom end of the tank body, and the threaded portion is threadedly connected inside the thread groove.

[0013] In the above technical solution, the utility model provides a leak-proof industrial oxygen tank, which has the following beneficial effects:

[0014] (1) By setting the valve member, when closing the nozzle of the oxygen tank, the handle can be turned so that the threaded rod squeezes the spring, so that the piston is tightly fixed inside the mounting tube with a large force to avoid leakage. At the same time, due to the design of the spring, if the oxygen tank falls down and the handle on the valve member is impacted and turned, the spring will still exert a force on the piston to prevent the piston from being easily opened by the oxygen inside the tank, thereby greatly improving the sealing of the nozzle of the oxygen tank.

[0015] (2) By setting up a base assembly, the bottom of the base is solid, which can make the bottom of the tank body heavier, making it difficult for the tank body assembly to fall when it is placed in the workshop due to scratches, thereby reducing the chance of the oxygen tank falling.

[0016] (3) When the oxygen tank falls due to a large impact, the enclosure can protect the valve components and prevent the parts of the valve components from colliding with the ground and being damaged, thereby reducing the probability of the handle being rotated due to impact.

Due to the design of the spring 18, when the oxygen tank falls down later and the handle 15 on the valve member 11 is impacted and rotated, the spring 18 will still exert a force on the piston 19 to prevent the piston 19 from being easily opened by the oxygen inside the tank body 7, thereby greatly improving the sealing performance of the oxygen tank nozzle. The piston 19 is installed at the bottom of the spring 18 by bolts, and three sealing rings 20 are sleeved on the outside of the piston 19. The three sealing rings 20 can improve the sealing performance between the piston 19 and the inner wall of the mounting tube 14. A mounting tube 13 is integrally formed on the outer wall of one side of the mounting tube 14, and a thread is provided at one end of the mounting tube 13 to facilitate the installation of an external pipeline and the mounting tube 14 together.

[0032] Example 2

[0033] This embodiment is further limited on the basis of embodiment 1, wherein a panel 9 is welded on the top of the tank body 7, the panel 9 can hold the valve member 11, prevent the parts of the valve member 11 from colliding with the ground and being damaged, and can reduce the probability of the handle 15 being impacted and rotated, the valve member 11 is located inside the panel 9, a through hole 10 is provided on the outer wall on one side of the panel 9, the through hole 10 is convenient for the external pipeline to extend into the interior of the panel 9, and the mounting pipe 13 is coaxial with the through hole 10; the base assembly 1 includes a base 3, a threaded groove 4 is provided on the outer wall at the top of the base 3, the threaded groove 4 cooperates with the threaded portion 8 to enable the tank body 7 to be installed on the base 3, a placement groove 5 is provided on the outer wall on one side of the base 3, and a ball 6 is provided inside the placement groove 5, the ball 6 facilitates the oxygen tank with the base assembly 1 installed to move on the ground, a threaded portion 8 is provided at the bottom end of the tank body 7, and the threaded portion 8 is threadedly connected inside the threaded groove 4.

[0034] Working principle: When carrying an oxygen tank, the tank body 7 can be tilted toward the side of the ball bearing 6 so that the ball bearing 6 can contact the ground, so that subsequent workers can pull the tank body 7 to move on the ground. When it reaches a suitable position, the tank body 7 can be straightened, and then the worker can insert the external pipe into the enclosure 9 through the through hole 10, so that the pipe can be installed in the installation pipe 13, so as to facilitate the subsequent use of oxygen. When the tank body 7 is placed on the ground, since the bottom of the base 3 is solid, the bottom end of the tank body 7 can be made heavier, so that the tank body assembly 2 is not easy to fall when it is placed in the workshop due to scratches, thereby reducing the probability of the oxygen tank falling. When the tank body 7 is subsequently touched, the enclosure 9 can protect the valve member 11, avoid the parts in the valve member 11 from colliding with the ground and being damaged, and can reduce the probability of the handle 15 being impacted and rotated. When the oxygen tank is not used later, the handle 15 can be rotated so that the threaded rod 16 squeezes the spring 18, so that the piston 19 is tightly fixed inside the mounting cylinder 14 with a large force to avoid leakage. At the same time, due to the design of the spring 18, when the oxygen tank falls down later and the handle 15 on the valve member 11 is impacted and rotated, the spring 18 will still apply a force to the piston 19 to prevent the piston 19 from being easily opened by the oxygen inside the tank body 7, thereby greatly improving the sealing of the oxygen tank nozzle.
