Description

Technical Field

[0001] The invention relates to the technical field, in particular to a quick locking connector for a gas cylinder. Background Art

[0002] Currently, the quick connectors for gas tank pipe openings on the market, such as patents 201020210394.0 and 201420351102.3, all use the principle of threaded connection of the pipe opening, which has the following problems during operation: 1. The joint opening needs to be balanced and aligned with the gas tank pipe opening. On the one hand, the interface must be supported to maintain the balance between the joint opening and the pipe opening. If it is slightly offset, the knob connection will cause the seal to not fit; 2. The knob joint opening is connected to the pipe thread, which is inconvenient to operate and the knob is laborious. Summary of the invention

[0003] The object of the present invention is to provide a method for using a gas cylinder quick-locking connector to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides a method for using a gas cylinder quick locking connector, including an assembly method, an installation method and a disassembly method. The gas cylinder quick locking connector includes a slipcover and a handwheel installed at one end of the slipcover, a socket is provided inside the slipcover, an externally threaded ventilation pipe is installed inside the handwheel, a clamping block is provided on the inner wall of the slipcover, a cylinder angle valve connecting port for connecting a cylinder angle valve is provided at one end of the socket, an inner spring clamping sleeve is provided on the outer wall of the socket, a plurality of steel ball holes are provided in a ring shape on the outer wall of the socket, steel balls are embedded and installed inside the steel ball holes, and the inner spring clamping sleeve is used to support the steel balls.

[0005] Preferably, a groove is formed on the outer wall of the loop.

[0006] Preferably, a loop spring is installed on the outer wall of the holder.

[0007] Preferably, a first retaining spring is provided on the outer wall of the holder for supporting the looper.

[0008] Preferably, one end of the externally threaded ventilation pipe is provided with a pressure reducing valve connection port connected to the interior thereof, an internally threaded hexagonal sleeve is installed on the outer wall of the externally threaded ventilation pipe, an internal hexagonal socket is provided inside the handwheel, and the internally threaded hexagonal sleeve and the internal hexagonal socket are snap-fitted together.

[0009] Preferably, the outer wall of the hand wheel is integrally formed with a plurality of convex teeth protruding outward.

[0010] Preferably, a second retaining spring is installed on the outer wall of the internally threaded hexagonal sleeve for clamping the hand wheel.

[0011] Preferably, a rubber sealing head is installed at the other end of the externally threaded vent pipe.

[0012] Preferably, a conical flange is provided at the front end of the internally threaded hexagonal sleeve, a shoulder for clamping the conical flange is provided in the socket, a conical spring is sleeved on the outer side of the conical flange, the conical flange holds the conical spring, and the other end of the conical spring is embedded in the inner wall of the inner spring sleeve.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In the gas cylinder quick locking connector, the steel ball rotates itself to facilitate the insertion of the cylinder angle valve into the holder. At the same time, the steel ball is automatically and firmly clamped on the inner side of the reinforcement rib of the cylinder angle valve under the action of the spring and the loop block, so that the cylinder angle valve can be quickly positioned, thereby ensuring a stable connection during the entire connection process.

[0015] 2. In the gas cylinder quick locking connector, the internal threaded hexagonal sleeve is rotated by rotating the hand wheel counterclockwise. When the internal threaded hexagonal sleeve rotates, the external threaded vent pipe is longitudinally extended into the inner cavity of the cylinder angle valve, and the rubber sealing head at the head of the vent pipe is pressed to seal, thereby realizing a quick locking connection between the body and the cylinder angle valve.

[0016] 3. In the gas cylinder quick locking connector, the rear end thread of the external threaded vent pipe can be matched with various gas appliances (including low-pressure valves, medium-pressure valves and gas welding guns, etc.).

[0017] 4. The quick locking connector of the gas cylinder is particularly suitable for the connection of the latest national standard cylinder self-closing angle valve. Through the telescopic function of the external threaded vent pipe, the self-closing device inside the cylinder self-closing angle valve can be directly opened to implement ventilation.

[0018] 5. In the gas cylinder quick locking connector, the device of the present invention can completely replace the threaded interface connection between the traditional pressure reducing valve and the cylinder angle valve, solving the problems of cumbersome operation and difficult connection when connecting the traditional pressure reducing valve and the cylinder angle valve, as well as time-consuming and laborious twisting when disassembling.

[0019] 6. The gas cylinder quick locking connector fully demonstrates the advantages of the device of the present invention in that it is time-saving, labor-saving, convenient and fast to operate, and achieves the effect of quick locking connection. BRIEF DESCRIPTION OF THE DRAWINGS
