The utility model has the advantages that: the utility model discloses a portable gas cylinder bottle neck protection device, through setting up with the sleeve of bottle neck valve block and stretch out in the straight-bar outside the guard shield, can operate the switch of bottle neck valve under the situation of installation guard shield, can align and install facilities such as relief pressure valve with operation window and the export of bottle neck valve simultaneously, guaranteed the protection of the bottle neck during the gas cylinder drops into use to also can satisfy the bottle neck protection of portable gas cylinder during transportation, storage.
Drawings
Fig. 1 is a schematic structural view of the movable gas cylinder mouth protector of the present invention.
In the drawing, 1, a shield, 2, a connecting screw hole, 3, an operation window, 4, a support seat, 5, a straight rod, 6, a limiting table, 7, a spring, 8, a sleeve, 9, a through hole, 10, a wire rope, 11, a bolt, 12, a wrench and 13, a chip groove are arranged.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The utility model provides a portable gas cylinder bottle neck protection device, as shown in figure 1, including guard shield 1, connection screw 2 has been seted up to guard shield 1's bottom, and operation window 3 has been seted up to guard shield 1's lateral wall, and guard shield 1's top is fixed with and has link up to the cavity supporting seat 4 in the guard shield 1 downwards, and the straight-bar 5 that both ends outwards stretched out about sliding sleeve has been closed in the supporting seat 4, sets up the through-hole 9 that the level link up to straight-bar 5 on the supporting seat 4, and guard shield 1's top is connected with the bolt 11 that the size of a dimension suited with through-hole 9 through cotton rope 10. A limiting table 6 is fixed at the top end of the straight rod 5, a T-shaped wrench 12 is fixed above the top end of the limiting table 6, a spring 7 is connected outside the straight rod 5 between the bottom end of the limiting table 6 and the top end of the supporting seat 4, and a sleeve 8 is fixed at the bottom end of the straight rod 5 in the shield 1.
Evenly spaced apart along the circumference of connecting screw 2 on the guard shield 1 and be equipped with a plurality of fore-and-aft junk grooves 13, can solve between guard shield 1 and the gas cylinder connecting thread, because of the inconvenient problem of dismouting that corrosion, foreign matter lead to. The number of the chip grooves 13 is not less than two, the width of each chip groove 13 is not less than 3mm, and the depth of each chip groove 13 is not less than 2mm.
The operation window 3 is reasonably set according to the size of safety accessories such as a pressure reducing valve and the like connected when the gas cylinder is used, the preferable width does not exceed 1/4 of the horizontal circumference of the protective cover 1, and otherwise, the safety protection effect is influenced.
When the gas cylinder is used, the connecting screw hole 2 of the protective cover 1 is aligned with the screw thread of the cylinder mouth of the gas cylinder and screwed, and if impurities or corrosion exist in the screw thread, the impurities or the corrosion can be led out through the chip groove 13. The sleeve 8 is disengaged from the mouth valve by the natural spring force of the spring 7 between the support base 4 and the stopper 6, and the sleeve 8 can be engaged with the mouth valve when the hand-press wrench 12 is rotated. When the gas cylinder needs to be put into use, the operation window 3 can be aligned with the outlet of the cylinder nozzle valve, facilities such as a pressure reducing valve and the like are installed, the rotary wrench 12 is pressed after installation is finished, the cylinder nozzle valve is unscrewed through the sleeve 8, and the gas cylinder can be put into use; when the gas cylinder is used, the rotating wrench 12 is pressed reversely, and the cylinder mouth valve is closed through the sleeve 8. If the bottle cap is not used for a long time, the straight rod 5 is aligned with the through hole 9 on the supporting seat 4 and the bolt 11 connected with the thread rope 10 is inserted, at the moment, the sleeve 8 is separated from the bottle mouth valve, and meanwhile, the wrench 12 can be locked to prevent misoperation of other people.
In this way, the utility model discloses a portable gas cylinder bottle neck protection device through set up with the sleeve 8 of bottle neck valve block and stretch out in the straight-bar 5 outside guard shield 1, can operate the switch of bottle neck valve under the situation of installation guard shield 1, can align and install facilities such as relief pressure valve with operation window 3 and bottle neck valve export simultaneously, guaranteed the protection of gas cylinder bottle neck during the use that drops into, and also can satisfy portable gas cylinder in the transportation, the bottle neck protection during the storage.
