A hood 1 and a bottom seat 3 of the steel cylinder are all connected fixedly with the cylinder body 2 through lugs. The steel cylinder is convenient to weld. The steel cylinder saves time and labour, saves raw materials and reduces cost. The quality of the steel cylinder meets the requirements of standard.

Description

A kind of steel cylinder

The utility model relates to a kind of liquid or gas containers such as splendid attire liquefied petroleum gas (LPG) of being used for.

The YSP-10 of domestic use; the YSP-15 liquefied petroleum ga steel cylinder is mainly by guard shield; cylinder ear; bottle; base is formed; wherein lap-welded form is adopted in the upper end of cylinder ear and bottle; the form of angle type welding is then adopted in the lower end of base and bottle; guard shield is again by three cover screws; nut; pads etc. are packed on the cylinder ear; because cylinder ear; the volume of base is little; the weld surface of contact is fitted bad; the heat radiation difficulty; weld seam speed is slow; and welder's stress; technical very difficult grasp; so incomplete fusion occurs through regular meeting; weldering partially; moulding is bad; problems such as undercut appear in bottle one side; be serious defective wherein in bottle one side undercut; because concentrating, stress also can cause steel cylinder gas leakage; catch fire or explosive accident,, need waste a large amount of man-hours again even repair through repair welding again; material and electric energy; also be difficult to make steel cylinder to become flawless product, thereby judge that by product standard GB5842 the said goods is a substandard product.

The purpose of this utility model is exactly will provide a kind of can make bottle and combining of guard shield and base is firm, simple in structure, cost is low steel cylinder.

In order to achieve the above object, technical solution of the present utility model is, the guard shield 1 that this steel cylinder comprises bottle 2, join with the bottle upper end, with the base 3 that the bottle lower end joins, its special way is, the bottom of guard shield 1 is provided with lug 4, and is fixedly connected by the upper end of this lug and bottle 2; The upper end of base 3 is provided with lug 5, and is fixedly connected by the lower end of this lug and bottle 2.

Described lug 4 can be an individual components, fixedly connected with guard shield 1, but mode of execution is preferably again, and lug 4 is to be turned up or be inverted to form by the bottom of guard shield 1, and lug and guard shield are an integral body like this, and the two is in conjunction with firmly; Secondly described lug 4 preferably is provided with through hole 6 with bottle 2 joining positions, is convenient to like this use welding technique by this hole, and lug is combined firmly with bottle.

In like manner, described lug 5 also can be an individual components, fixedly connected with base 3 again, but mode of execution is preferably, lug 5 is to be turned up or be inverted to form by the top of base 3, and lug 5 is an integral body with base 3 like this, and soundness is big, and lug 5 preferably also is provided with through hole 7 with bottle 2 joining positions, is convenient to combine with bottle by this hole.

The number of lug 4,5 can be set at 2-8 as required, but with three better.Because the utility model has adopted above-mentioned technical solution, make the welding of lug 4,5 and bottle easy, time saving and energy saving, and overcome incomplete fusion that welding is prone to, weldering partially, moulding is bad and defective such as bottle one side undercut, removed and done over again, save raw material and electric energy, reduced the manufacture cost of product, guarantee to make the steel cylinder quality reach standard-required.

The utility model is described in further detail below in conjunction with accompanying drawing:

Accompanying drawing and drawing explanation:

Fig. 1 is the plan view of steel cylinder;

A kind of structural representation that Fig. 2 combines with bottle for guard shield;

The another kind of structural representation that Fig. 3 combines with bottle for guard shield;

The third structural representation that Fig. 4 combines with bottle for guard shield;

A kind of structural representation that Fig. 5 combines with bottle for base;

The another kind of structural representation that Fig. 6 combines with bottle for base;

The another kind of structural representation that Fig. 7 combines with bottle for base.

Wherein, bottle 1, guard shield 2, base 3, lug 4 on the guard shield and through hole 6, lug 5 on the base and through hole 7.

Embodiment 1: with reference to figure 1, Fig. 2, Fig. 6.Steel cylinder comprises bottle 2, guard shield 1 and base 3, and wherein the bottom of guard shield 1 is provided with equally distributed 3 lugs, and lug 4 is to be turned up by the bottom of guard shield 1 to form, and is provided with through hole 6 at lug 4 and bottle 2 joining positions; Guard shield 1 is linked together with the upper end of bottle 2 by carrying out plug welding in the through hole on lug 46, and in conjunction with firm, tight.The top of base 3 is provided with 3 equally distributed lugs 5, and lug 5 is to be turned up by the top of base 3 to form, and the position that lug 5 is connected with bottle 2 is provided with through hole 7.3 of bases are to link together with the lower end of bottle 2 by carrying out plug welding in the through hole on lug 57, and in conjunction with firm, tight.

Example 2: with reference to figure 1, Fig. 3, Fig. 5.

The bottom of guard shield 1 is inverted to form lug 4 and is linked together with the upper end of bottle 2 by carrying out plug welding in the through hole on lug 46, and in conjunction with firmly tight.
