Abstract

The utility model relates to a handlebar for a hand-operated coiler device, particularly a handle folding crank for winding ropes, and a handle of the handle folding crank can be rotated and folded. The utility model comprises the handle and a connecting rod and is characterized in that a pin shaft is arranged at a connecting position of the connecting rod and the handle. The utility model is the same with a standard crank when the utility model is used. When the utility model is not used, the handle of the crank can be rotated 180 DEG around the pin shaft to cause the handle to face to a fixed wall surface or a plain surface, and therefore, the handle is not projected out of the connecting rod. The handle can not hurt people or can not damage people's clothes.

Description

The collapsible hand crank of handle

The utility model relates to a kind of handle of hand coiler device, particularly a kind of collapsible hand crank of handle of handle portion rotatable folding of the rope that is used to reel.

Existing crank is for easy to use, often adopt handle perpendicular to a connecting rod and an outstanding minimum hand length, so that staff grips, it is connected with an end of connecting rod, connecting rod is again perpendicular to rotating shaft, the other end of connecting rod also drives an end of rotating shaft, rotating shaft drives the reel that is wound with rope again, rope is twined or emit, the other end of rotating shaft is through being fixedly mounted on because of reservation on metope or other plane object, and so a kind of normal structure makes the whole distance that coiler on metope or the plane will protrude in a rotating shaft distance of metope and a handle that is fixed on, and this outstanding distance can cause many inconveniences, and is also not attractive in appearance; As be used on the lift-type clothes-drying rack, coiler is placed in the balcony metope of the height that staff exerts all one's strength easily, and this highly often is to child's height in naughty stage, often collide with easily child's head of the handle of apicule, damage, perhaps handle tangles clothes and spoils a dress.

In view of this, how to reduce all inconveniences that crank causes because of outstanding metope as far as possible, simultaneously can also be easy to use, simple in structure, after the installation, appearance looks elegant, this novel wound motivation place of grinding just.

The utility model designer relies on the practical experience of being engaged in fields such as all kinds of gearing parts production and processing researchs for many years, on the basis of feasibility study repeatedly, does a brand-new design and constitutes, and gets generation of the present utility model eventually.

At the deficiencies in the prior art, this novel purpose is the collapsible hand crank of a kind of handle of design, and it is when reeling use, and is identical with standard coiler form, and when not using, the handle rotatable folding makes handle can not protrude in connecting rod.

The purpose of this utility model can be by following realization, and the utility model comprises handle and connecting rod, it is characterized in that connecting rod and handle junction are provided with a bearing pin and are connected.Connecting rod stretches out a type linking arm being connected a distal process with handle, and linking arm is provided with the hole that can pass bearing pin; Handle is a camber at an end that is connected with connecting rod, and the middle part of this end is provided with the hole that can pass bearing pin; Handle camber end is inserted between connecting rod type linking arm and by bearing pin and is connected and fixed; Connecting rod is provided with a conduit being connected an end with handle, is provided with a spring in the conduit, and spring one end is fixed in the conduit, and the other end is fixed a steel ball; The handle link is provided with at least one arc groove; The handle link is provided with two relative arc grooves.

The utility model is identical with the standard crank in use, when not using, can be center of circle Rotate 180 degree with the bearing pin, make handle towards fixing metope or plane with the handle of crank, make handle not protrude in connecting rod, handle can not damage human body or spoils a dress because of cracking between the teeth to bump.

Further illustrate the utility model below in conjunction with accompanying drawing embodiment,

Fig. 1 be the utility model handle with connecting rod link rotating part bit position cross-sectional schematic.

Fig. 2 is the utility model side-looking structure chart.

1 ... bearing pin 2 ... steel ball

3 ... spring 4 ... connecting rod

5 ... rotating shaft 6 ... handle

7 ... handle link 8 ... crank

9 ... type linking arm 10 ... conduit

11 ... groove

Referring to accompanying drawing, the utility model comprises handle 6 and connecting rod 7, connecting rod is provided with a bearing pin 1 with handle junction and is connected, make that handle 6 can be center of circle rotation with bearing pin 1, connecting rod 4 stretches out a type linking arm 9 being connected a distal process with handle 6, type linking arm is provided with the hole that can pass bearing pin, and the supply and marketing axle passes; Handle is a camber at an end that is connected with connecting rod, is convenient to rotation, and the middle part of this end is provided with the hole that can pass bearing pin; Handle 6 camber links 7 are inserted in 9 of connecting rod type linking arms and the hole passed separately by bearing pin is connected and fixed; Connecting rod 4 is provided with a conduit 10 being connected an end with handle 6, is provided with a spring 3 in the conduit 10, and spring one end is fixed in the conduit, and the other end is fixed a steel ball 2; Handle link 7 is provided with at least one arc groove 11, the location of handle and connecting rod when being used for user mode; Handle is being provided with two relative arc grooves 11 with the connecting rod link, steel ball 2 just in time can be stuck in the groove 11, make handle and connecting rod locate, handle is just in time vertical with connecting rod during the location, and two grooves are relative, and steel ball is when just in time being stuck in groove, and then handle just in time is in user mode and obsolete rotary folding state respectively.

Shown in Fig. 1 solid line, steel ball 2 is stuck in the groove 11 the utility model in use, and handle 6 vertical links 4 are also outwards outstanding, and staff just in time grips, and rotary handle 6 makes connecting rod 4 rotations, connecting rod 4 rotate and can drive rotating shaft 5 rotations again; When not using, be axle center Rotate 180 degree with bearing pin 1, make handle 6, to avoid projection outside connecting rod and all inconvenience that produces towards reverses direction with handle 6.

In sum, this is novel to utilize simple structural design, makes crank can avoid outstanding connecting rod at time spent handle not, can avoid that handle may bring to the human injury and spoil a dress, and wholely on attractive in appearance, suitable improvement is also arranged.Obviously the utility model is the new design of a kind of novelty, progress and dark tool practicality.The above is specific embodiment of the utility model and the know-why used, the equivalence that the novel conception of Ruo Yiben is done changes, when the function that it produced does not exceed spiritual that specification and accompanying drawing contain yet, all should be in this novel scope, explanation hereby.
