Pull type power joint adjustable hose reel and cart

Abstract

The invention provides a pull type power joint adjustable hose reel and cart. The hose reel and cart is a pull type hand-push electric joint adjustable multi-purpose hose reel and cart with an electromagnetic pump valve and with a function curve concave channel matching with a hose winder of a position lock of a ball crank handle pin, and the cam profile curves of the position lock are all partially approximately similar constant-speed spiral of polar equation of Archimedean spiral taking an axial center (03) as the pole; a concave ball groove at the end part of a locking shaft (80) of a crankhandle pin (60) is provided with a ball (80C) provided with a short pin cotter (80d), and a ball bearing (83f) is arranged on a following rotating shaft (83) to form the ball crank handle pin; and the hose reel and cart is provided with the electromagnetic pump valve (84) so as to meet the requirements of high pressure and flow regulating, and the inner side edge (53f) of a locking projection part (53e) is an approximately similar cubic curve for mitigating the impact. The pull type power joint adjustable hose reel and cart has the beneficial effects that the problem of occasional jam is solved, the whole stable operation is guaranteed, and the requirements of high pressure and flow regulating 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 a pull-type power adjustable joint water hose vehicle with a hose reel equipped with a ball turn and a position lock for the handle pin. 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 and buttons To rotate and adjust the h...

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 problem. The international market forecast requires a trolley box type labor-saving adjustable multi-purpose water pipe truck with a high-precision position lock and a joint and an electromagnetic pump valve. It combines a lifetime of domestic and foreign senior engineering experience and multi-function. A new type of pull-type power adjustable joint hose truck came into being
