Abstract

The utility model relates to an automatic return position type handle, which comprises a handle arm shaft which is provided with a spring and is arranged in a housing of the handle arm; the lower end is connected with a draw rod; the lower end of the draw rod is connected with a hanging ear on a handle through a tension spring; a transmission sleeve on the upper end of the housing of the handle arm is arranged on a tooth wheel on the external side of a core shaft; a pin of the handle arm on the upper end of a shaft of the handle arm extends into corresponding pin holes on the tooth wheel, and one end of the handle is hinged with the housing of the handle arm. The automatic return position type handle has the advantages that the operation can be conveniently conducted with a single handle, and when the operation is not conducted, the handle can be folded and can be parallelly closed with the housing of the handle arm. Simultaneously, the handle arm can retract as the automatic pin; the clothing can be prevented from being scraped and torn, etc. The automatic return position type handle is an ideal accessory of various dense frames.

Description

The self-return handle

The utility model relates to a kind of self-return handle, belongs to intensive annex, is particularly suitable for all kinds of intensive and goes up dress usefulness, also can be used for other cashier's office in a shop.

Be loaded on an intensive end in the past, be used to make the handle of displacement before and after it, between normally castellated spring is set, need withstand on the other hand during use with anti-detachment, another is hand moving, and particularly when holding data on the other hand, another hand just can't be operated to the user and make troubles, simultaneously because handle can not fold this just to having increased new scraping again with regard to crowded reference room pulled probability originally, this handle arrangement complexity is arranged again, manufacturing process is loaded down with trivial details, cost is high, therefore, the numerous and confused requirement of user should be improved.

The purpose of this utility model is to provide that a kind of simple in structure, easy to manufacture, cost low energy is folding, a hand is with regard to operable self-return handle.

The purpose of this utility model is to realize by the following technical solutions, it comprises that the shaft arm axle which is provided with spring is loaded in the shaft arm shell, the lower end links to each other with pull bar, the lower end of pull bar links to each other with hangers on the handle by extension spring, the drive sleeve of shaft arm shell upper end is loaded on the outer gear wheel of mandrel, the shaft arm pin of shaft arm axle upper end puts in the corresponding pin-and-hole on the gear wheel, and an end of handle is hinged with bearing pin and shaft arm shell.

Be provided with Handle axis in the described handle, offer the stopper slot that matches with spacer pin on it, the other end is equipped with spring, and taper knob is set on the handle.

Described shaft arm shell with the corresponding site of shaft arm axle bottom on be provided with locating piece.

The spring wire of described extension spring directly is greater than the spring wire footpath of spring.

The utility model compared with prior art, owing to adopted shaft arm pin with shaft arm axle upper end to insert or extract a series of technical measures such as the interlock of corresponding pin-and-hole on the gear wheel wall and disengaging mode, and through evidence have one hand just to be convenient to operation, handle can be turned up with the shaft arm shell is parallel and draw close when not working, make the withdrawal of shaft arm pin simultaneously, prevent to scrape advantages such as pulling clothing, and simple in structure, reduce cost.
