Description

The novel steel cylinder cap of pressed gas steel cylinder

Technical field:

The present invention relates to a kind of accessory of pressed gas steel cylinder.Particularly a kind of novel steel cylinder cap of pressed gas steel cylinder.

Background technique:

The pressed gas steel cylinder is a kind of packing material that holds pressed gas commonly used, is provided with seal arrangement and in order to inflation with the connection set of gas at its bottle mouth position.In order to protect the Security of sealing device and connection set in transportation, when using, adopt on the pressed gas steel cylinder at present, as accessory the steel cylinder cap is set.This steel cylinder cap is circular high cap shape; the cap mouth is provided with internal thread; when the pressed gas steel cylinder dispatches from the factory; with the bottle mouth position of this steel cylinder calotte at the pressed gas steel cylinder; cooperate with the outside thread of steel cylinder mouth with the internal thread of cap mouth and to screw; this steel cylinder cap then can play the seal arrangement of protection pressed gas steel cylinder and the effect of connection set, and it is not collided in the way of transportation and carrying.But,, when joining, must remove this steel cylinder cap and could operate with external inflation with the pipeline of gas because the pressed gas steel cylinder is in use.After removing this steel cylinder cap, the staff because the carelessness or improper use, usually can not in time this steel cylinder cap of removing in time be loaded onto, therefore, this steel cylinder cap with after usually be dropped; And the pressed gas steel cylinder is reusable packing material, in frequent transportation and inflation repeatedly, in the gas process, this steel cylinder cap that also is easy to be furnished with when dispatching from the factory is lost, make the seal arrangement of gas pressure steel cylinder bottle mouth position and the safety of connection set lose guarantee, cause the potential safety hazard of gas pressure steel cylinder.

Summary of the invention:

The utility model aims to provide a kind of novel steel cylinder cap of pressed gas steel cylinder.It is fixed on the bottleneck of pressed gas steel cylinder, and the pressed gas steel cylinder needn't be removed when inflating and operating with gas; Not only deducted the operation of removing and screwing on the steel cylinder cap, the convenience of operation is provided, the particularly important is, fixing protective gear has guaranteed the safety of pressed gas steel cylinder.

The utility model comprises fastening ring, cap body and operation window.Wherein, fastening ring is provided with internal thread and opening is arranged; The open end of fastening ring is provided with bolt hole, can be with bolton; Operation window is located on the cap body; Fastening ring and cap body lower end fuse; The open end of fastening ring is the lower edge of operation window.As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4.

Bolt hole of the present utility model can have safe edge.

When the pressed gas steel cylinder dispatches from the factory, because the lower edge that fastening ring open part of the present utility model is an operation window, therefore make lower end of the present utility model, comprise the opening end of fastening ring and the lower edge of operation window, be the expansible shape, therefore, be enclosed within the bottle mouth position of pressed gas steel cylinder after fastening ring of the present utility model can being opened, and make operation window aim at the pressed gas steel cylinder bottle mouth position inflation and with the connection set of gas, mesh with the internal thread of fastening ring and the outside thread of pressed gas steel cylinder bottleneck.Bolt is screwed in the bolt hole of fastening ring opening end; fastening effect with bolt; fastening ring is fixedlyed connected with the bottleneck of pressed gas steel cylinder, and the seal arrangement of pressed gas steel cylinder and connection set promptly are among the protection of cap body of the present utility model, can avoid collision and damage.

Pressed gas steel cylinder of the present utility model is housed in use, because its connection set that is used to inflate and use gas is over against operation window, therefore, and can direct control by operation window, the pipeline of connection set with the external world is connected, very convenient.

When pressed gas steel cylinder of the present utility model being housed in use repeatedly repeatedly, owing to all can operate during in inflation with gas by operation window, therefore, the utility model is fixed on the bottle mouth position of pressed gas steel cylinder all the time, makes that the safety of pressed gas steel cylinder is guaranteed reliably.

In sum, the utility model is a kind of novel steel cylinder cap of pressed gas steel cylinder.When it is fixed on the bottleneck of steel cylinder, the inflation of steel cylinder and can normally carry out with gas operation; Deducted the operation of removing and screwing on the steel cylinder cap during not only in the inflation of steel cylinder with gas, the convenience of operation is provided, the particularly important is, fixing protective gear has guaranteed the safety of pressed gas steel cylinder.

Embodiment:

Embodiment 1:

Think that 40 liters of supporting the utility model of seamless pressed gas steel cylinder are example;

For making the boost bottleneck of strength body steel cylinder of fastening ring 1 and 40 supporting, fastening ring 1 diameter is 80 millimeters, is provided with the internal thread 7 that matches with the outer rib-loop of pressed gas steel cylinder bottleneck; Cap body 2 diameters suitable for reading are 60 millimeters, and fastening ring 1 fuses with cap body 2 lower ends, and whole height is 110 millimeters, cap body 2 is provided with two relative operation window 3, and the lower edge of one of them operation window 3 is open parts of fastening ring 1, as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4.

Two operation window 3 that cap body 2 is provided with aim at respectively on the bottleneck of pressed gas steel cylinder with gas and inflation connection set, the opening end and the place, operation window 3 lower edges of fastening ring 1 are opened, just can make fastening ring 1 by using gas and inflation connection set, be enclosed within on the bottleneck of pressed gas steel cylinder, its internal thread 7 is promptly engageable with the outside thread of the bottleneck of pressed gas steel cylinder, bolt 5 is linked to be circle by bolt hole 4 with fastening ring 1, and fixedlys connected with pressed gas steel cylinder bottleneck.Like this; cap body 2 just becomes the sealing on the pressed gas steel cylinder bottleneck and the protecting jacket of connection set, because this connection set is in the window of operation window 3, when connection set need be connected with the pipeline in the external world; can directly operate by operation window 3, very convenient.The utility model will be fixed on the bottle mouth position of pressed gas steel cylinder all the time, make that the safety of pressed gas steel cylinder is guaranteed reliably.

Periphery at bolt hole 4 can also increase safe edge 6, and is as Fig. 8, shown in Figure 9; Safe edge 6 can be avoided causing loosening because of collided gudgeon 5 in carrying or the using process; And, being screwed in the bolt in the safe edge 6, must just can turn on special tool, guarantee the safety of pressed gas steel cylinder more.
