Abstract

The utility model relates to a universal joint structure which is composed of a containing seat and a transferring pole, wherein a containing hole is arranged at an axial position of one side of the containing seat and can be used for connecting transferring joints of a transferring pole. After the transferring joints of the transferring pole are connected, the transferring joints are punched at the radial position of the outer part of the containing hole; thus, the neck part of each transferring joint is limited. The containing seat and the transferring pole are pivoted into a whole, so the transferring joints of the transferring pole can freely rotate in the containing hole.

Description

Universal joint mechanism

Technical field

The utility model relates to a kind of universal joint mechanism, mainly be to be applied on the holding base and the engagement technique between the adapting rod of universal joint, this holding base is provided with corresponding receiving hole and conversion adapter with the side that adapting rod overlaps, only need to impose punching press and handle, need not to use and wear the tip and promptly holding base and adapting rod can be pressed into one in the receiving hole outside.

Background technique

The universal joint of conventional known please be consulted Fig. 1, shown in Figure 2: be known three-dimensional combination and perspective exploded view.With shown in Figure 3: be known user mode schematic representation.Its structure mainly is: this universal joint by holding base 10, adapting rod 20, spring S1, wear tip P and formed; Wherein:

The axial place of these holding base 10 1 sides is provided with circular receiving hole 11, and as holding the usefulness that spring S1 and adapting rod 20 are set, this holding base 10 is radially located to run through and is provided with circular tip hole 12 circular receiving hole 11 outsides, as wearing the tip P pivot knot usefulness of adapting rod 20 is set;

These adapting rod 20 1 sides are provided with spheroidal conversion adapter 21, the size of this spheroidal conversion adapter 21 just can be contained in the circular receiving hole 11 of holding base 10, and can in circular receiving hole 11, freely rotate, radially the locating to run through of this spheroidal conversion adapter 21 is provided with arc tip hole 22, the available tip P that wears runs through the circular tip hole 12 of holding base 10 and the arc tip hole 22 of adapting rod 20, holding base 10 is connected with adapting rod 20 forms one.

But still there are following several problem and the shortcomings that wait to overcome solution in the universal joint of above-mentioned conventional known at least on practical operation is used:

One, this holding base 10 and circular tip hole 12 and arc tip hole 22 that adapting rod 20 is run through can destroy holding base 10 and adapting rod 20 whole structural strengths own.

There is the hole enlargement of doing punch riveting to handle though two, this wears tip P two ends, but under external force, still can cause the situation that tip P deviates from from circular tip hole 12 of wearing, that deviates from wears tip P except meeting scratch personnel, the danger that also can cause the universal joint mechanism in the use to disintegrate.

When three, the spheroidal conversion adapter 21 of this adapting rod 20 rotates in the circular receiving hole 11 of holding base 10, mainly be the spring-go tension force that utilizes spring S1, prevent that spheroidal conversion adapter 21 from rotating, but the torsion that can bear be relatively poor.

Summary of the invention

The utility model at the universal joint of conventional known existing problem and shortcoming, a kind of universal joint mechanism is proposed.

In order to achieve the above object, the utility model proposes a kind of universal joint mechanism, comprising: holding base and adapting rod, the axial place of this holding base one side is provided with receiving hole, this adapting rod is provided with conversion adapter at the axial place of a corresponding side, and the inside of this receiving hole can be provided with spring and conversion adapter; Wherein the exterior circumferential of this receiving hole corresponding to the conversion adapter neck radially locate impose punching press and handle, limit the neck of conversion adapter thus, conversion adapter can freely be rotated in receiving hole, so that this holding base and this adapting rod are combined into one.

According to universal joint of the present utility model mechanism, wherein this receiving hole and conversion adapter are provided with in correspondence with each other polygon limit face and polygon cambered surface.

The utility model deals with problems one, the effect one of two applied technological means and contrast prior art, two are: the holding base of this universal joint is provided with corresponding receiving hole and conversion adapter with adapting rod, and impose punching press in the receiving hole outside and handle, the neck of conversion adapter is restricted, with this holding base and switching bar pivot are struck up partnership, the conversion adapter of adapting rod can freely be rotated in the receiving hole of holding base, owing to give up the pin pivot junction mode of conventional known, so except can not destroying holding base and adapting rod main body structure intensity, can also avoid deviating from the scratch personnel that caused and the danger of disintegrating because wear the tip.

The utility model deal with problems three applied technological means and the contrast prior art effect three be: the holding base of this universal joint and adapting rod also can be provided with polygon limit face and polygon cambered surface at receiving hole that overlaps and conversion adapter, thereby can be when conversion adapter rotates, occluding relation between increase and the receiving hole improves the torsion that can bear with this.
