Abstract

The utility model relates to a steam pump for manpower vehicles, comprising a retaining clip, a pump body, a piston, a crank case, a crank shaft and a rotating wheel. A rotating shaft is arranged on the pump body by a bearing; one end thereof is connected with the rotating wheel, and the other end is connected with the crank shaft; the piston is arranged at the upper end of the crank shaft and makes up-and-down movement in company with the rotation of the crank shaft; the compressed-air is input into the inner tube of a manpower vehicle by an exhaust vent and a connecting pipe. The utility model can be convenient for arranging on various manpower vehicles, and has the advantages of large air displacement, time saving and labour saving.

Description

Steam pump for manpower vehicle

The utility model relates to a kind of pump class, the heat pump that particularly a kind of rickshaw is used.

Development along with the bicycle production technology, various multi-speed bicycles, mountain bike have occupied very big market, because the populous economy of China is also not really flourishing, so bicycle still is the main traffic tool in short-term, the pump that is used for the bicycle inner tube inflation now is not suitable for going out to carry because volume is big, efficient is low, rolled bad tire in case go out, have to the go-cart walking, and, use just harder for the bigger rickshaw of inner tube of a tyre volume ratio.

The purpose of this utility model provides a kind of rickshaw heat pump that is installed on the various rickshaws.

The utility model is to realize like this, this rickshaw heat pump comprises fixing clamp, the pump housing, piston, crankcase, bent axle and runner, rotating shaft by Bearing Installation on the pump housing, one end and runner link, and the other end and bent axle link, and are provided with piston in the upper end of bent axle, piston is along with the rotation of bent axle moves up and down, and with in the inner tube of a tyre of pressurized air by exhaust port and connecting leg input rickshaw.

The utility model can be installed on each rickshaw easily, and it is big to have air displacement, saves time, the labour-saving advantage.

Below in conjunction with accompanying drawing the utility model is further described,

Fig. 1 is embodiment 1 a structural representation,

Fig. 2 is the left view of Fig. 1;

Fig. 3 is embodiment 2 a structural representation,

Fig. 4 is the left view of Fig. 3;

Shown in Fig. 1-4, embodiment 1; This rickshaw heat pump comprises the pump housing 1, piston 2, crankcase 3, bent axle 4 and runner 5, rotating shaft 6 is installed on the pump housing 1 by bearing 7, the pump housing 1 is provided with radiating fin 8, resuscitation apparatus 11, suction valve 9 and outlet valve 10, one end and the runner 5 of rotating shaft 7 link, the other end and bent axle 4 link, be provided with piston 2 in the upper end of bent axle 4, during use, teeth on the runner 5 can be leaned on mutually with the teeth of rickshaw rotating disk, or runner 5 is connected with the rotating disk of bicycle and rotating disk is rotated backward with chain, piston 2 is along with the rotation of bent axle 4 moves up and down, and pressurized air is input in the inner tube of a tyre of rickshaw by exhaust port 10 and connecting leg, adopt the splash system lubrication mode lubricated in addition in the pump housing 1, heat pump can be installed on the rickshaw by fixing clamp 12.

Embodiment 2, can change the piston among the embodiment 12 into leather cup 13, and radiating fin 8 is not set.
