Portable multi-purpose water pipe vehicle

Abstract

The invention relates to a portable multi-purpose water pipe vehicle. The portable multi-purpose water pipe vehicle is a portable hand-push electric multipurpose water pipe vehicle which is provided with a pipe winding device, an belt joint and an electromagnetic pump valve, wherein the pipe winding device is provided with a position lock with a function curve concave channel and a ball crank pinin a matched mode, the cam profile curve of the groove edge of an inner cam groove (53n) of the position lock is a constant velocity spiral line with the polar coordinate equation, wherein the constant velocity spiral line is partially and approximately similar to an Achimedean spiral line which takes the axis (03) as a pole, the cam profile curve of the groove edge of an outer cam groove (53w) isa cam profile curve which is partially and approximately similar to an equiangular spiral line, namely a logarithmic spiral line so as to achieve the effect that the pressure angles are the same at all positions, a ball (80C) with a short cross pin (80d) is arranged on the concave ball groove at the end part of a lock travelling shaft (80) of the crank pin (60), and a ball bearing (83f) is arranged on a rotating shaft (83) to form the ball crank pin.

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 a portable hand-push electric hose reel equipped with a ball crutch to lock the position of the pin, and a multi-purpose hose truck with joints and electromagnetic pump valves. 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 conjoined gear rings and gears, springs...

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 predicts that portable hand-push electric vehicles with high-precision position locks and multi-purpose water pipe trucks with joints and electromagnetic pump valves will be required. Portable multi-purpose hose truck came into being
