Description

Universal sleeve

Technical field

The utility model is related to a kind of Universal sleeve, espespecially a kind of Universal sleeve bearing high torsion.

Background technology

Existing a kind of Universal sleeve for being connected to pneumatic, electric tools and using, referring to Fig. 8, it is predominantly using female The caulking groove 81 of seat 80 is connect with the bulb 91 of adapter piece 90, and the pivoted hole 83 and bulb 91 of female seat 80 are arranged in bolt 87 Eight word holes 911 in, 87 both ends of bolt with riveting method fix female seat 80 on, utilize eight word holes 911 of bulb 91 and round bar The cooperation of shape bolt 87 makes adapter piece 90 can be relative to 80 Sloped rotating of female seat, and changes connection angle.

However, such Universal sleeve has the disadvantage that when cooperation is pneumatic, electric wrench operates：1. the Universal sleeve Bolt 87 is the element for the torsion for being primarily subjected to female seat 80 and adapter piece 90, to be easiest to the part of damage；2. because bolt 87 with Eight word holes 911 of bulb 91 are the tangential contact of plane and cylindrical surface, therefore by the torsion of female seat 80 and adapter piece 90 when holds Concentrated stress is easily formed, bolt 87 is made to be more easily broken off；3. after the pivoted hole 83 of female seat 80 bears excessive torsion, being easy from pivot The wall surface for connecing hole 83 to the minimum range of 80 ora terminalis of female seat splits；4. as riveting when assembled is poor quality, bolt 87 is in high speed Operating is lower to be easy to loosen, and makes part because inertia is thrown away, and injures user；5. existing Universal sleeve is in wide-angle and high speed When operating, connection type easy tos produce vibrations, and the employment injuries of user's hand is be easy to cause after long-time service.

Utility model content

In view of the missing of above-mentioned Universal sleeve, the purpose of this utility model is to provide a kind of Universal sleeves, to improve Eight word holes of bulb and bolt connection coordinate and bolt and female seat are caused to be easily damaged and be easy to cause user's hand occupation The problem of injury.

Another main purpose of the utility model be to provide one kind can bear it is larger hold up torsion, and bulb and female seat Connection is not likely to produce the Universal sleeve that shakes and can be promoted relative rotation angle of inclination.

In order to achieve the above objectives, the Universal sleeve of the utility model includes：

One female seat, includes a first direction, a caulking groove, two elongated slots, multiple slots, and the wherein caulking groove is recessed in the female seat It is interior, and opening is formed along one end of first direction in the female seat, two elongated slots all extend in a first direction setting, are located at the female seat phase It is communicated to both sides and with the caulking groove, multiple slot runs through the peripheral wall set on the female seat and communicated with the caulking groove；

One adapter piece, one end is equipped with a bulb, and the bulb is equipped with one and runs through pivot hole, and the bulb of the adapter piece is set to should In the caulking groove of female seat；

One bolt is in rod-shaped, and its length dimension is more than the maximum outside diameter of the adapter piece bulb, which is arranged in this and connects In the pivot hole of head, and its both ends protrudes from the bulb and is placed at two elongated slots of female seat, the pivot hole of the bolt and the adapter piece Between be clearance fit；

One elastic element pushes against the bulb for supporting the adapter piece in the caulking groove of the female seat；

Multiple limit beads, are located in respectively in a slot of the female seat, and protrude the caulking groove of the female seat, and to the connector The bulb of part forms clip；And

One latch closure, is sheathed on the periphery wall of the female seat, and closes the opening of each slot.

Two elongated slots of above-described Universal sleeve, the wherein female seat are all groove, from the open end of the caulking groove along first Direction is recessed in caulking groove peripheral wall.

Two elongated slots of above-described Universal sleeve, the wherein female seat are all through hole, and are arranged in the peripheral wall of the female seat, And the latch closure covers at least partially open of two elongated slots, and the bolt is located at the openings of two elongated slots of the female seat and is masked place.

Above-described Universal sleeve, wherein two elongated slots of the female seat are all formed in the open end of the caulking groove and are open.

Above-described Universal sleeve, it is preferable that the periphery wall of the latch closure and the female seat is interference fit.

Above-described Universal sleeve, it is preferable that the female seat periphery wall is equipped with a limiting stand, and the latch closure is far from the mother The limiting stand for terminating in the female seat is supported in one end of seat caulking groove open end.

Using above-mentioned technical characteristic, the Universal sleeve of the utility model has effects that following：

1. the utility model is using the connection type of bolt and two elongated slots of female seat, providing the adapter piece can be relative to female seat It is rotated with angle of inclination, and the bulb of the bolt and adapter piece is the design close to integral type, increases the intensity of bolt, improved existing There are bolt and bulb to connect the shortcomings that stress is easy to concentrate with eight word holes, and then promotes torsion that bolt can be born and universal The torsion specification that sleeve can be driven；And using the connection of elongated slot and bolt, female seat is made to bear torsion with the side wall of two elongated slots, improve Female seat is easy, from the problem of rupture with the tender spots of the pivoted hole of bolt, to increase the service life of each part.

2. the utility model fixes the bulb of the adapter piece using the cooperation clip of latch closure, limit bead and elastic element, The elastic element provides the bulb support force of adapter piece, other than it can prevent bulb from being detached with female seat, also makes bulb pushing and pressing limit Bead and clip is formed to latch closure, be different from the past using eight word holes, connecting mode of inserted pin, or with c-type retaining ring clip bulb Caused by rotate the limitation at angle of inclination, make the smooth degree of adapter piece and female seat relative rotation and rotate angle of inclination to reach It maximizes；And when wide-angle is connected and run at high speed, vibrations are not likely to produce, and the employment injuries that can improve user's hand is asked Topic.

3. the utility model has the advantages that each design of part is simple and assembling mode is easy.
