Abstract

The utility model relates to a liquefied petroleum gas cylinder with an automatically drawing back hook, which is mainly composed of a cylinder (6), a hood (5), a nose ring (2), a hook (1) and a return spring (3). The utility model is characterized in that the hook (1) which is in the vertical state is stuck on the hood (5), the direction of the hook is outward, the hooked end is positioned on the upper part and the ring-shaped end is positioned on the lower part, the ring-shaped end and the return spring (3) are strung on the nose ring (2) and can rotate along the nose ring (2) as a shaft. In application, the hook (1) can be hung on an article carrier of a bicycle only by lifting the cylinder (6). When the cylinder (6) sags naturally, the hook (1) and the hood (5) are separated automatically. When the cylinder (1) is lifted, the hook is disengaged from the article carrier of the bicycle, drawing back and sticking to the hood (5).

Description

A kind of liquefied petroleum ga steel cylinder of automatic contraction hook

The utility model relates to a kind of civil LPG steel cylinder that automatic contraction hook is housed.

The civil LPG steel cylinder is when transporting with bicycle, and the user needs to tie up or make in addition hook with rope, not only bothers but also inconvenient.China's utility model patent of approved (patent No.: 87200032, x.) described a kind of liquefied petroleum ga steel cylinder that has hook is not though need system hook in addition, still inconvenience to some extent.Its a kind of scheme is will link up with to change down by the grasswort hand hole on the steel cylinder shield to take in the guard shield inboard, and another kind of scheme then is that hook is fixed on outside the guard shield.Previous scheme is stretched out on must will linking up with earlier in use and changeing, and changes income down with must linking up with opposite action again after finishing.Though latter approach does not need above-mentioned action, be fixed on the outer hook of guard shield and pull other outer objects of bottle easily.

The purpose of this utility model is needn't pull out hook earlier when utilizing hook carrying liquefied petroleum ga steel cylinder, also needn't take in hook after finishing.And hook is given unprincipled protection to cover, unlikely bottle outer other objects of pulling with finishing promptly automatic subsides the in back.

Content of the present utility model is that cylinder for liquefied gas has the hook of making and stretches out in use, with finishing the structure that shrink automatically the back.Existing accompanying drawings is as follows: (numeral behind the component names is the numbering of drawing in the accompanying drawing in addition) the utility model is made of steel cylinder (6), guard shield (5), nose-ring (2), hook (1), return spring (3), cushion rubber bumper (4).Nose-ring (2) welds or is fixed on the guard shield (5) with nut, window catch shape hook (1) is vertical, unciform end is last, hook is to outwards, looped end is following, together go here and there on nose-ring (2) with return spring (3), hook (1) looped end can be that axle rotates with the nose-ring, the hook bar is partly clamped for folder shape, folder shape in return spring (3) stage casing, and spring clip shape both sides rotation direction is opposite, there is the U-shaped card at return spring (3) two ends, block nose-ring (2), make the unlikely horizontal play of hook (1), and make hook (1) when not using, keep standing position to be attached on the guard shield (5).Between hook (1) and guard shield (5), cushion rubber bumper (4) is housed, in order to avoid hook (1) and guard shield (5) bump flashing.Cushion rubber bumper (4) can be rectangular or its alloytype shape, press or riveting in the pre-drilled hole of guard shield (5).The utility model structurally with known utility model patent (patent No.: 87200032, x.) difference, hook does not take the position of guard shield hand hole grasswort, the portable steel cylinder of user is more convenient.

The utility model and known utility model patent (patent No.: 87200032, x.) compare and have the following advantages: at first, because hook does not take guard shield hand hole grasswort position, the portable steel cylinder of user is more convenient; Secondly, needn't earlier hook be pulled out in the guard shield hand hole when user hangs up automatic vehicle shelf with liquefied petroleum ga steel cylinder,, also will not link up with in the income guard shield hand hole when when automatic vehicle shelf takes off steel cylinder.In addition,, can not pull bottle outer other objects because hook is attached on the guard shield with regaining voluntarily after finishing yet, more favourable to mechanical auto-filling liquid gas.

Among above-mentioned each figure, it is identical that identical in addition parts are drawn numbering.

Existing accompanying drawings realizes mode of the present utility model.On the guard shield (5) of steel cylinder of the present utility model (6) nose-ring (2) is housed, nose-ring (2) is fixed on the guard shield (5) with welding, nut or other suitable forms.Nose-ring (2) is gone up string fenestrate hook-shaped hook (1) and return spring (3).Window catch shape hook (1) unciform end is last, and hook is to outwards, and the garden looped end is enclosed within on the nose-ring (2) down, can serve as an axle rotation with nose-ring (2).Return spring (3) middle part is the folder shape, clamps hook (1) shank, and folder shape both sides spring rotation direction is opposite, be enclosed within on the nose-ring (2), return spring (3) two ends are " U " shape, are stuck in nose-ring (2) two ends, make hook (1) be standing position, be attached on the guard shield (5), and unlikely left and right sides play.In hook (1) and guard shield (5) contact segment, cushion rubber bumper (4) is housed, in case link up with (1) not time spent resilience and guard shield (5) bump generation spark.Cushion rubber bumper (4) or leave flange and be pressed into guard shield (5) and go up bore in the good hole, or the boring riveting of rubber cushion (4) both sides is on guard shield, and cushion rubber bumper (4) is rectangle or other suitable shapes.When the user used the utility model, only with hand stretched in the grasswort hand hole, mentions cylinder for liquefied gas, to link up with (1) takes on the automatic vehicle shelf, along with steel cylinder (6) tenesmus, hook (1) separates with guard shield (5) automatically, and steel cylinder (6) is hung the jail on automatic vehicle shelf.When taking off steel cylinder (6), only with hand stretches in the grasswort hand hole, mentions cylinder for liquefied gas, and hook (1) is thrown off automatic vehicle shelf automatically under return spring (3) effect, paste and give unprincipled protection to cover (5).The user does not need will to link up with (1) with specific actions and pulls out or take in, and hook (1) not the time spent be attached on the guard shield (5), can not pull other outer objects of bottle, hook (1) does not take hand hole, lifts conveniently, has finished the utility model proposes of task.
