Trolley-case-type labor-saving adjustable water pipe vehicle

Abstract

The invention relates to a trolley-case-type labor-saving adjustable water pipe vehicle which is a trolley-case-type multipurpose water pipe vehicle with an electromagnetic pump valve and a pipe winding device. The pipe winding device is provided with a position lock with a ball crank pin matched with a concave groove with a function curve. Cam profile curves of groove edges of an internal cam groove (53n) and an outer cam groove (53w) of the position lock are constant velocity spirals of a polar coordinate equation of Archimedes spiral with partial approximate similarity and taking axis (03)as a pole. A ball (80C) with a short horizontal pin (80d) is arranged at a concave ball groove in the end of a locking shaft (80) of the crank pin (60), and a following rotating shaft (83) is providedwith a ball bearing (83f) to form the ball crank pin. The water pipe vehicle is provided with the electromagnetic pump valve (84) in order to meet the requirements of high pressure and regulating flow. The trolley-case-type labor-saving adjustable water pipe vehicle has the beneficial effects that the problem of occasionally getting stuck is solved, and the overall smooth operation is ensured andthe needs of high pressure and regulating flow are met.

Description

technical field [0001] The present invention relates to the technical field of pipeline winding device and water pipe car device, in particular to a garden water pipe car with function curve improved on the basis of winding hoses or cables and fast buckling. It is equipped with a multi-purpose water hose car with a trolley box type labor-saving adjustable hose reel with a ball turn and a position lock for the handle pin, and an electromagnetic pump valve with a joint. Background technique [0002] Existing garden hose carts for storing flexible pipes or cables are moved by the operator pushing the handle. But the handfeel of existing metal handle is relatively poor; If will cover plastic hose outside the curved metal handle, certain trouble and difficulty again. In addition, in order to reduce the size for collection and storage, some existing metal handles, also known as handrail tubes and frame tubes, use rotary connectors. The adjustment mechanism is composed of conjoine...

AI Technical Summary

Problems solved by technology

However, the existing metal handles have a poor feel; if a plastic hose is to be installed outside the curved metal handle, it will be troublesome and difficult.

In addition, in order to reduce the size for collection and storage, some existing metal handles, also known as handrail tubes and frame tubes, use rotary connectors. The adjustment mechanism is composed of conjoined gear rings and gears, springs and buttons To rotate and adjust the handle through the axial clutch; however, sometimes there are problems that the locking operation is not easy to control during use and the reliability and stability are insufficient; although the above-mentioned gear ring and gear structure are usable, they occasionally fail and get stuck phenomenon occurs

Furthermore, if a tool box and a quick connector are provided, it will be convenient for the operator; if a quick buckle is provided, it is also very convenient; the position lock of the original handle pin is reliable and stable for the occasional failure of the hose reel The problem of insufficiency is a long-standing and difficult problem. The international market forecasts require a trolley box type labor-saving adjustable multi-purpose water pipe truck with joints and electromagnetic pump valves with high-precision position locks. In summary, a multi-functional water pipe truck of the present invention A new type of trolley box labor-saving adjustable water hose truck came into being
