Abstract

The utility model relates to an inflator for the tyre of a bicycle or a tricycle. The utility model is mainly formed by that a fixed oil ring which is matched with a leather cup which can move up and down is assembled at the bottom of the air pipe of the existing structure; thus the leather cup is dipped with partial oil, the oil is carried onto the inner wall of the inflator, accordingly the complete sealing action is achieved, and the service life of the leather cup is prolonged. The upper end of an inflating rod on the inflator is hinged with a compression rod, one end of the compression rod is hinged with a pull rod hinged on a base, and the other end of the compression rod is sheathed with a sleeve compression rod. After used, the objects can be folded to be loaded into a case to be fixed on vehicle frames. The utility model has the advantages of small volume, convenience for carrying, convenient use, etc.

Description

Oil type high pressure air pipe

The utility model relates to the air-inflating device of bicycle or tricycle tire, is oily formula high-pressure air pipe specifically.

At present to inflate the tracheae of usefulness big because of volume for bicycle or tricycle tire, can not adorn onboard, meets and go away, and do not have the shop that repairs on the road again, and tire have to push away car when not having gas and walking, and is the thing that part is had a bad headache, now the tracheae that uses, because leather cup does not have oil lubrication, poor sealing, and easily gas leakage.

The purpose of this utility model is to avoid above-mentioned deficiency of the prior art and provides a kind of volume little, use light, the oily formula high-pressure air pipe of good seal performance.

The purpose of this utility model can reach by following measure:

A kind of oily formula high-pressure air pipe, comprise assembling gas bar moving up and down in the inflator, gas bar lower end is assembled pad, leather cup and catch successively, check valve guard bowl at the bottom of the inflator is done to open sealing with the check valve on being assemblied in stage clip and is cooperated, check valve guard bowl inner chamber communicates with the steam outlet pipe of the outer assembling of inflator, its special way is: the solid oil ring of assembling cooperates with leather cup moving up and down at the bottom of the inflator, the hinged depression bar in inflating rod upper end, depression bar one end is hinged with the pull bar that is hinged on the base, and end is socketed with the sleeve depression bar in addition.

Inflator of the present utility model, hinged depression bar, pull bar, sleeve depression bar all can be loaded in the box body, box body by bolt on vehicle frame.

Accompanying drawing and description of drawings:

Fig. 1 is oily formula high-pressure air pipe structural representation.

Fig. 2 cuts open structural representation for oily formula high-pressure air pipe side office.

Fig. 3 is a folded state diagram in the oily formula high-pressure air pipe box.

Among the figure: at the bottom of the 1-box, 2-screw, 3-pin, 4-lid, the 5-steam outlet pipe, 6-depression bar, 7-nut, 8-sleeve depression bar, the 9-upper end cap, 10-inflating rod, 11-inflator, 12-pad, the 13-check valve, 14-base, 15-stage clip, the solid oil ring of 16-, 17-check valve guard bowl, 18-catch, the 19-leather cup, 20-pull bar, 21-nut.

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

A kind of oily formula high-pressure air pipe, comprise assembling gas bar 10 moving up and down in the inflator 11, gas bar 10 lower ends are assembled pad 12 successively, leather cup 19 and catch 18, the check valve guard bowl 17 of inflator at 11 ends done to open sealing with the check valve 13 on being assemblied in stage clip 15 and cooperated, check valve guard bowl 17 inner chambers communicate with the steam outlet pipe 5 of inflator 11 outer assemblings, its special way is, the solid oil ring 16 that inflator assembles at 11 the end cooperates with leather cup 19 moving up and down, the hinged depression bar 6 in inflating rod 10 upper ends, depression bar 6 one ends are hinged with the pull bar 20 that is hinged on the base 14, and end is socketed with sleeve depression bar 8 in addition.

Inflator 11 of the present utility model, hinged depression bar 6, pull bar 20, sleeve depression bar 8 all can be loaded in the box body, box body by bolt on vehicle frame.

Open the lid 4 during use, inflating rod 10 is connected with depression bar 6 usefulness attaching nuts, again sleeve depression bar 8 is placed on the depression bar 6, carry inflating rod 10 on when inflating, gas is entered in the inflator 11 by vent slot and leather cup inlet hole, leather cup pad 12 compressing leather cups 19 are sealed the leather cup inlet hole when pressing down, and to pressing down, check valve 13 on the base and of the effect of check valve guard bowl 17 by stage clip 15, make it separately, gas enters steam outlet pipe 5, owing to set up the solid oil ring 16 of spongy oil suction in the tracheae bottom, made leather cup 19 soak part oil, and oil is taken on the cylinder inner wall, so not only make leather cup 19 and tracheae 11 inwalls play complete seal action, and prolonged the working life of leather cup 19.After tyre inflation finishes, sleeve depression bar 8 is unloaded,, be against the tracheae place after the gathering, close lid 4 and lock and get final product because depression bar 6 is collapsible with pull bar 20.

The utility model compared with prior art has following advantage:

1, oily formula high-pressure air pipe, volume is little, in light weight, and collapsible mounted box is fixed on the car, the convenient use.

2, oily formula high-pressure air pipe good airproof performance, it is time saving and energy saving to inflate, the leather cup long service life.
