Description

Technical Field

[0001] The utility model belongs to the technical field of gas cylinder protection devices, and in particular relates to a gas cylinder valve protection device which can be quickly disassembled and assembled. Background Art

[0002] At present, most gas cylinder valve guards are manufactured with steel round helmet-type guards. However, the steel round helmet-type guards cannot be connected to the pipeline without removing the guards. Therefore, the gas cylinder cannot be used without removing the guards. When the gas cylinder is to be filled or the gas is to be used, the guards need to be removed. At this time, if the gas cylinder falls over or the valve is hit, the gas cylinder valve cannot be effectively protected. Moreover, during the automated filling operation, the automated filling equipment cannot automatically disassemble and assemble the guards, and the construction of a full-process automated filling production line cannot be realized.

[0003] In the prior art, a protective cover for a gas cylinder is disclosed with publication number CN106917959A. The protective cover is used for a gas cylinder. The protective cover is fixedly locked to the gas cylinder by means of a clamping plate assembly or a threaded structure in combination with a fastening assembly. Utility Model Content

[0004] The technical problem solved by the utility model is to overcome the problem in the prior art that the gas cylinder protective cover cannot effectively protect the gas cylinder valve when the gas cylinder is used or filled, and provide a gas cylinder valve protection device that can be quickly disassembled and assembled.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A gas cylinder valve protection device that can be quickly disassembled and assembled comprises a protection cover and a hoop sleeve, wherein a thread structure matching with the gas cylinder neck protection thread is arranged on the inner side of the protection cover, and the hoop sleeve is arranged on the outside of the protection cover; arc-shaped fixing structures are arranged on both sides of the outer side of the protection cover, and an arc-shaped gradual boss and a groove matching with the arc-shaped fixing structure are arranged on the inner side of the hoop sleeve; the arc-shaped gradual boss and the groove are arranged adjacent to each other in sequence on the hoop sleeve, the arc-shaped gradual boss abuts against one end of the protection cover, and the other end of the protection cover is a movable end, and the protection cover is driven to be locked inward by rotating the hoop sleeve; the arc-shaped gradual bosses on the inner side of the hoop sleeve are distributed symmetrically with the center, and are used to lock the two sides of the protection cover.

[0007] The protective cover is in an inverted cone shape and has hollows on both sides.

[0008] The hoop sleeve is circular, and a gear-like tooth structure is arranged on the outer side of the hoop sleeve.

[0009] The groove is arranged between the arc-shaped gradual boss and the inner wall of the hoop sleeve, and the arc-shaped fixing structure is arranged at the concave part of the groove.

[0010] The arc-shaped fixed structure and the arc-shaped gradual boss both adopt a semi-crescent arc-shaped gradual structure.

[0011] The boot and hoop are a nylon and fiberglass blend.

[0012] The utility model has the following beneficial effects: compared with the steel gas cylinder shield in the prior art, the utility model has lower material cost, better product quality consistency and can be mass-produced by injection molding. The utility model can be quickly disassembled and assembled and meets the supporting operation of the automated gas cylinder filling system, and can meet the automatic loading and unloading of fixtures or disassembly of gas cylinder shields by the manipulator. When the gas cylinder valve is hit or dropped, the utility model can play a good role in buffering and protecting the valve, preventing damage to the valve, and even preventing the valve from breaking and causing a greater accident.

[0019] like Figures 1 to 3 As shown, a gas cylinder valve protection device that can be quickly disassembled and assembled includes a protection cover 1 and a hoop 2. The inner side of the protection cover 1 is provided with a thread structure 4 that matches the gas cylinder neck protection thread, and the hoop 2 is arranged on the outside of the protection cover 1; arc-shaped fixing structures 3 are provided on both sides of the outside of the protection cover 1, and the inner side of the hoop 2 is provided with an arc-shaped gradual boss 5 and a groove that matches the arc-shaped fixing structure 3; the arc-shaped gradual boss 5 and the groove are arranged adjacent to each other on the hoop 2 in sequence, the arc-shaped gradual boss 5 abuts against one end of the protection cover 1, and the other end of the protection cover 1 is a movable end, and the protection cover 1 is driven to be locked inward by rotating the hoop 2; the arc-shaped gradual boss 5 on the inner side of the hoop 2 is symmetrically distributed around the center, and is used to lock the two sides of the protection cover 1.

[0020] The protective cover 1 is in an inverted cone shape and has hollow portions on both sides.

[0021] The hoop 2 is circular, and a gear-like tooth structure 6 is provided on the outer side of the hoop 2 .

[0022] The groove is arranged between the arc-shaped gradual boss 5 and the inner wall of the hoop 2, and the arc-shaped fixing structure 3 is arranged at the concave part of the groove.

[0023] The arc-shaped fixing structure 3 and the arc-shaped gradual-changing boss 5 both adopt a semi-crescent arc-shaped gradual-changing structure.

[0024] The protective cover 1 and the hoop sleeve 2 are made of a mixed material of nylon and glass fiber.

[0025] Specifically, Figures 1 to 5 As shown, the protective cover 1 is put on the outside of the gas cylinder valve, and the threaded structure 4 on the inside of the protective cover 1 cooperates with the thread of the gas cylinder neck guard; the hoop 2 is arranged on the outside of the protective cover 1, and the arc-shaped fixing structures 3 on both sides of the outside of the protective cover 1 are arranged in the depressions of the groove inside the hoop 2. At this time, one end of the protective cover 1 abuts against the arc-shaped gradual boss 5, and the other end of the protective cover 1 is a movable end; the hoop 2 is rotated to drive the protective cover 1 to shrink inward and lock it on the gas cylinder. At this time, the arc-shaped fixing structure 3 abuts against the inner wall of the hoop 2 through the groove to lock the hoop and the protective cover; when disassembly is required, the hoop 2 only needs to be rotated ninety degrees in the opposite direction to complete the quick disassembly.

[0026] Specifically, the protective cover 1 of the utility model is hollowed out on both sides, so the protective cover 1 and the hoop 2 do not need to be removed during the use or filling of the gas cylinder, and can play a good protective role on the gas cylinder valve during the use or filling process; a gear-like tooth structure 6 is also provided on the outside of the hoop 2, which can increase the friction force during manual disassembly and assembly, and is convenient for relevant personnel to operate, and is also convenient for the clamping and fixing of the robot claw during the filling process; after continuous testing and adjustment, it is determined that the protective cover 1 and the hoop 2 are made of a mixed material of nylon and glass fiber, and the mixing ratio is 50% nylon plus 50% glass fiber, which reduces the cost while ensuring its hardness and stability.
