[0005] A fixing bar is installed just below the bottom of the base.

[0006] Furthermore, handles are provided on both sides of the top shell for providing support during transportation, a top shell cover is welded on the top of the top shell, and an annular groove is provided on the top shell cover.

[0007] Furthermore, the size of the fixing strip is matched with the inner diameter of the annular groove. When the liquefied petroleum gas bottles need to be stacked after use, the fixing strip is snap-fitted onto the annular groove to fix the bottle body so that it will not tip over.

[0008] Furthermore, when the top shell is snap-fitted and installed in the groove, the threaded hole is horizontally aligned with the through hole.

[0009] Furthermore, the bolt is threadedly installed on the threaded hole through the through hole outside the groove, so as to fix the position of the top shell.

[0010] Furthermore, the groove is designed in an annular structure, and the bottom size of the top shell is matched with the inner diameter size of the groove.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. A groove is arranged in the top shell of the liquefied petroleum gas cylinder to be connected with the top shell by a clamping connection, and then fixed by bolts. When maintenance is needed, the top shell can be disassembled and then maintained.

[0013] 2. In the top shell of the liquefied petroleum gas cylinder, a fixing strip whose size matches the inner diameter of the annular groove is provided. When the liquefied petroleum gas needs to be stacked after use, the fixing strip is snap-fitted onto the annular groove to fix the bottle body so that it will not tip over, thereby effectively increasing space utilization.

[0026] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0027] See also Figure 1-Figure 4As shown, the purpose of this embodiment is to provide a liquefied petroleum gas cylinder top shell, including a base 3, a bottle body 2 is welded on the base 3, a valve seat 5 is installed at the top center of the bottle body 2, a hand wheel 4 is installed just above the valve seat 5, a groove 7 is opened at the top edge of the bottle body 2, a through hole for fixing the bolt 6 is opened at the center of the outer side of the groove 7, a top shell 1 is clamped and installed inside the groove 7, and a threaded hole 61 is opened at the bottom center of the top shell 1. It also includes:

[0028] The fixing bar 31 is installed just below the bottom of the base 3 .

[0029] The top shell is provided with handles 12 on both sides for providing support during transportation. A top shell cover 11 is welded to the top of the top shell 1 , and an annular groove 111 is provided on the top shell cover 11 .

[0030] The size of the fixing strip 31 matches the inner diameter of the annular groove 111. When the liquefied petroleum gas bottles need to be stacked after use, the fixing strip 31 is snap-fitted and installed on the annular groove 111 to fix the bottle body 2 so that it will not fall over.

[0031] When the top shell 1 is snap-fitted and installed in the groove 7 , the threaded hole 61 is horizontally aligned with the through hole, and at this time, the bolt 6 can be threadedly installed through the through hole and the threaded hole 61 .

[0032] The bolt 6 is threadedly installed on the threaded hole 61 through the outer through hole of the groove 7, and is used to fix the position of the top shell 1. When the bolt 6 is tightened, the top shell 1 is firmly fixed in the groove 7, so that the top shell 1 will not fall off, thereby ensuring that the liquefied petroleum gas cylinder will not be accidentally impacted and exploded.

[0033] The groove 7 is designed in an annular structure, and the bottom size of the top shell 1 is matched with the inner diameter size of the groove 7, so that the top shell 1 can be normally inserted into the groove 7.

[0034] Working principle:

[0035] When maintenance is needed, the base 3 is fixed, and the bolts 6 outside the bottle body 2 are unscrewed. At this time, the top shell 1 can be directly lifted up and removed. After the maintenance is completed, the top shell 1 is aligned with the groove 7, the top shell 1 is clamped in the groove 7, and the bolts 6 are passed through the through hole and aligned with the threaded hole 61 for threaded installation, and the maintenance process is completed. When the liquefied petroleum gas is used up and the empty bottles need to be stacked, the fixing strip 31 provided just below the base 3 can be clamped and installed on the top shell cover 11 to achieve the purpose of stable stacking.

[0036] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
