Description

TECHNICAL FIELD

[0001] The utility model belongs to steel bottle technical field, concretely relates to a kind of anti-reuse steel bottle. BACKGROUND

[0002] Steel bottle is mainly used for storing high-pressure oxygen, gas, petroleum liquefied gas and the like, and the requirement for safety is particularly high. After use, the general non-reusable steel bottle should be recycled by the manufacturer. Some unscrupulous people will recycle the used steel bottle, cut off the old safety valve and re-weld a new safety valve, and then sell the old steel bottle as a new one after painting, which causes great safety hazards. After recycling by unscrupulous people, it is difficult to identify the refurbished steel bottle.

[0003] According to Patent No. CN209705704U, an anti-reuse steel bottle belongs to the technical field of gas containers. It solves the problem that existing steel bottles cannot prevent unscrupulous people from using old steel bottles to pretend to be new ones. The utility model discloses an anti-reuse steel bottle comprising a bottle body having an inner cavity and a safety valve provided at the top of the bottle body. The top of the bottle body is provided with a valve port, and the valve body of the safety valve is in sealing and fixed connection with the valve port. A protrusion is provided on the outer periphery of the valve body, and a protective sleeve is provided on the valve body between the protrusion and the bottle body. The protective sleeve is tightly pressed between the protrusion and the bottle body. The lower end of the protective sleeve is fixedly connected with the bottle body or the valve body. The outer periphery of the protective sleeve is marked with an identification code, which can be a combination of numbers, graphics or words. The utility model has the advantages of easy identification after refurbishment, discouraging unscrupulous people from refurbishing, fast liquid injection speed, simultaneous liquid supply to two places, high safety, stable gas supply, etc.

[0004] In the above technical solution, although the protective sleeve and the safety valve have different diameters, unscrupulous people can choose a valve body with the same diameter as the protective sleeve for assembly and welding. This welded interface is not conducive to identification by the buyer, reducing the identification degree of refurbished steel bottles. UTILITY MODEL CONTENTS

[0005] The utility model aims to provide an anti-reuse steel bottle to solve the problem of identifying refurbished steel bottles and the identification degree of refurbished steel bottles in the prior art.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0007] An anti-reuse steel bottle comprises a bottle body and a welding head, the welding head is welded at the top end of the bottle body, a valve body is installed above the bottle body, the valve body is in sealing and fixed connection with the bottle body, an identification column is provided below the valve body, and an identification code is marked on the outer wall of the identification column; a protective assembly is installed on the outer side of the valve body.

[0008] Further, the two sides of the welding head are provided with handle windows, and the upper inner side of the handle window is provided with an arc-shaped bending piece which is inwardly bent.

[0009] Further, the identification column is in a tapered structure which is narrow at the top and wide at the bottom.

[0010] Further, the identification column is provided with equidistant split lines which are inwardly recessed.

[0011] Further, the rear side of the welding head is provided with a circular cutout, and a groove is formed below the circular cutout, and the protection assembly is welded in the groove.

[0012] Further, the protection assembly comprises a protection sheet metal which is in a U shape and a welding tail plate which is arranged at the tail end of the protection sheet metal and is welded with the groove.

[0013] Further, the valve body is arranged in the U-shaped protection sheet metal, and the bottom of the protection sheet metal is welded with the top of the bottle body. The protection sheet metal is put into the circular cutout, and then the welding tail plate is inserted into the groove, and the valve body is arranged in the U-shaped protection sheet metal, and the bottom of the protection sheet metal is welded with the top of the bottle body. Therefore, when the valve body is cut, the protection sheet metal must be cut first, so that the protection sheet metal will leave residues after cutting, and the cutting time of the valve body and the subsequent processing process are improved, and the identification degree of the refurbished bottle is also improved.

[0014] Further, the U-shaped opening of the protection sheet metal is consistent with the direction of the valve body output end. When the valve body output end is connected with a pipeline, the pipeline can be prevented from being shielded by the protection sheet metal.

[0015] The technical scheme of the utility model has the following beneficial effects:

[0016] 1. After the identification column which is narrow at the top and wide at the bottom is cut, the identification column with different shapes at both ends is obtained. Even if a similar valve body is used for re-welding by the illegal person, a different diameter difference exists between the two welding parts, and very obvious welding traces are left on the welding parts, so that the identification degree is improved.

[0017] 2. The split line which is inwardly recessed will be deformed after cutting, so that the cutout is irregular, and the identification degree of the refurbished bottle is further improved. The split line is composed of irregular lines or regular groups of lines. The split line should avoid being a regular straight line. Therefore, when a new valve body is re-welded by the illegal person, it is difficult to align the split line, so that the identification degree of the refurbished bottle is further improved.

[0018] 3. When cutting the valve body, the protective sheet metal must be cut first. Therefore, the cut protective sheet metal will leave residue, which increases the cutting time for criminals and the subsequent processing steps, and also increases the identification of refurbished products.

[0027] Example 1:

[0028] refer to Figures 1-4 A reusable steel cylinder includes a cylinder body 10 and a welding head 11. The welding head 11 is welded to the top of the cylinder body 10. A valve body 20 is installed above the cylinder body 10. The valve body 20 is sealed and fixedly connected to the cylinder body 10. An identification post 201 is provided below the valve body 20. The outer wall of the identification post 201 is marked with an identification code.

[0029] The identification code on the outer wall of the identification column 201 can be numbers, graphics or characters and their combinations, which highlights the integrity of the entire valve body 20; when the valve body 20 is cut off, the identification code is destroyed, and it is easier to identify the refurbished steel cylinder.

[0030] It should be noted that the identification code is preferentially arranged vertically on the identification column 201, so that when cutting from the identification column 201, the cutting position can be ensured to fall on the identification code.

[0031] Further reference Figure 1 and Figure 3 The handle window 12 is provided on both sides of the welding head 11, and the arc-shaped bending part 13 is provided on the upper inner side of the handle window 12 and bends inward. Placing the hand into the handle window 12 and holding the arc-shaped bending part 13, the inwardly bent arc-shaped bending part 13 can greatly reduce the pressure of the hand, avoiding the problem of hand pain when carrying the steel cylinder.

[0032] Preferably, the identification column 201 is tapered, narrow at the top and wide at the bottom;

[0033] The identification column 201 is provided with a split line 202 at equal intervals on the surface, and the split line 202 is recessed inwardly to the identification column 201;

[0034] In the preferred embodiment, the identification column 201 with narrow top and wide bottom will have two identification columns 201 with different shapes after cutting. Even if the criminal uses a similar valve body 20 to re-weld, there will be a difference in diameter between the two welding, and the welding trace will be very obvious, thereby improving the resolution;

[0035] The split line 202 recessed inwardly will be deformed after cutting, causing irregular cutting, which further improves the identification of the refurbished steel cylinder. The split line 202 is composed of irregular lines or regular groups of lines. The split line 202 should avoid being a regular straight line, so that the criminal is difficult to align the split line 202 when re-welding a new valve body 20, thereby further improving the identification of the refurbished steel cylinder.

[0036] Reference Figures 1-5 The rear side of the welding head 11 is provided with a circular cutout 14, and the lower side of the circular cutout 14 is provided with a slot 15, and the protection assembly is welded in the slot 15;

[0037] The valve body 20 is provided with a protection assembly outside. The protection assembly includes a protection sheet metal 301 and a welding tail plate 302. The protection sheet metal 301 is in a U shape, and the welding tail plate 302 is arranged at the tail end of the protection sheet metal 301. The welding tail plate 302 is welded with the slot 15.

[0038] The welding installation of the protection assembly is simple, the protection sheet metal 301 is put into the inside of the circular cutout 14, then the welding tail plate 302 is inserted into the slot 15, and the valve body 20 is arranged in the U-shaped protection sheet metal 301, the bottom of the protection sheet metal 301 is welded with the top of the bottle body 10, so that the protection sheet metal 301 must be cut first when the valve body 20 is cut, thus the protection sheet metal 301 after cutting will leave a residue, the cutting time of the valve body 20 by the illegal person and the subsequent processing procedure are increased, and the identification degree of the renewed bottle is also increased.

[0039] Further, the U-shaped opening of the protection sheet metal 301 is consistent with the direction of the output end of the valve body 20, and the pipeline connected with the output end of the valve body 20 can be prevented from being shielded by the protection sheet metal 301.

[0040] The specific implementation process of the utility model is as follows:

[0041] The identification column 201 with the narrow upper part and the wide lower part will present the identification column 201 with different shapes at two ends after cutting, even if the illegal person uses a similar valve body 20 to re-weld, a difference in diameter will exist between the two welding parts, and very obvious welding traces will be left on the welding parts.

[0042] The split line 202 recessed to the inside will be deformed to cause irregular cutouts after cutting, and the identification degree of the renewed bottle is further improved; the split line 202 is composed of irregular lines or a plurality of lines with rules, and the split line 202 should avoid being a regular straight line, so that the illegal person is difficult to align the split line 202 when re-welding a new valve body 20, and the identification degree of the renewed bottle is further improved.

[0043] The protection sheet metal 301 must be cut first when the valve body 20 is cut, thus the protection sheet metal 301 after cutting will leave a residue, the cutting time of the valve body 20 by the illegal person and the subsequent processing procedure are increased, and the identification degree of the renewed bottle is also increased.
