Abstract
The utility model relates to a socket crank. The purpose of the utility model is to provide the socket crank which can reduce or even eliminate the friction between the hand and a socket. The socket crank comprises a socket head and a socket rod, the socket head is firmly connected with one end of the socket rod, the socket rod is shaped like an n, the other end of the socket rod is provided with a handle, which is movably connected with the socket rod through a connecting assembly, the connecting assembly consists of a connector and a bearing, an inner race of the bearing is firmly connected with the socket rod through the connector, and an outer race of the bearing is firmly connected with the handle. Since the handle is arranged on the end of the socket crank and connected with the socket rod through the bearing, the friction between the socket rod and the palm can be reduced or even eliminated when the socket rod is rocked, consequently, the injury of the palm, which can be caused by the socket rod, is prevented, the needed operating force is reduced as well, the working condition of workers is improved, and the labor intensity is reduced.
Description
Technical field
The utility model relates to a kind of frock, and in particular, the utility model is a kind of sleeve crank that is used for the assembling of automobile industry securing member.
Background technology
In the manufacture process that is welded of automobile industry, there is quite a few stamping parts to connect by bolt.Wherein there are the part parts to relate to vehicle body outward appearance coupling, in assembling, adjustment process, need dismounting repeatedly to adjust connecting bolt.Be subjected to the restriction of mounting process, generally adopt sleeve crank spanner to carry out the degree of tightness of connecting bolt.When operation, operating personnel one hold crank, shake crank on the other hand.When rotating crank, crank produces friction with the hand of holding crank.Because workload is big, crank damages the hand of holding; Simultaneously crank and the frictional force of holding the crank palm have also increased operating personnel's physical consumption.
Patent Office of the People's Republic of China has announced a CN2120712U document on November 4th, 1992, name is called the tire sleeve tube, this tire sleeve by socket bar, collet head, be positioned at the collet head center and form along the polygonal hole of socket bar axis, crank etc.The shortcoming of this sleeve is exactly when shaking sleeve, holds the frictional force that the hand of sleeve and sleeve produce, and has increased required operating physical force, and operating personnel's hand is also damaged.
Summary of the invention
The utility model for solve exist in the prior art when shaking sleeve, hold the hand of sleeve and the frictional force that sleeve produces, increased required operating physical force,, provide a kind of sleeve crank that can reduce even eliminate frictional force between hand and the sleeve the problem that operating personnel's hand also damages.
The technical scheme that its technical problem that solves the utility model adopts is: the utility model comprises collet head, socket bar, collet head is fixedly connected on an end of socket bar, socket bar is " several " font, and the other end of socket bar is provided with handgrip, and handgrip flexibly connects by jockey and socket bar; Jockey comprises connector, bearing, and the inner ring of bearing is fixedlyed connected with socket bar by connector, fixedlys connected with handgrip in the outer ring of bearing.End at socket bar is provided with handgrip, and handgrip and socket bar flexibly connect, and one holds handgrip when operation, on the other hand the shaking sleeve bar; Socket bar rotates and handgrip does not rotate; Handgrip is connected with socket bar by jockey, can reduce the frictional force between handgrip and the socket bar greatly, thereby has avoided the palm injury to operating personnel, and has reduced required operating physical force; Bearing is the most common standard active connection, has the advantage that frictional force is little, cost is low.
As preferably, connector is divided into three sections, is followed successively by polygon prismatic, cylindrical, small cylindrical, and the diameter of small cylindrical is less than columniform diameter, and the end of socket bar is provided with interface depression, that match with polygon prismatic; Small cylindrical and bearing inner race tight fit.Though the inner ring of bearing can directly be fixedlyed connected with socket bar, can make a handgrip be used for a plurality of sleeve cranks by the connector connection, save cost.
As preferably, polygon prismatic is positive hexagon prismatic.Big, easy to make advantage that positive hexagon prismatic has the moment of bearing.
As preferably, the inwall of handgrip and described bearing tight fit, the outer wall of handgrip is provided with anti-skidding striped.Can make operating personnel more firmly hold handgrip at the handgrip outer wall draw runner line of setting up defences, play anti-skidding effect.
The beneficial effects of the utility model are: the end at the sleeve crank is provided with handgrip, handgrip is connected with socket bar by bearing, reduce even eliminated the frictional force between socket bar and palm when the shaking sleeve bar, both eliminated the injury of socket bar to palm, also reduced required operating physical force, improve workman's working condition, reduced labour intensity.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model sleeve crank;
Fig. 2 is a kind of assembly relation schematic diagram of handgrip and socket bar in the utility model sleeve crank.
Among the figure: 1. socket bar, 2. collet head, 3. handgrip, 4. connector, 5. bearing, 6. interface, 7. outer ring, 8. inner ring, 9. inwall.
The specific embodiment
Below by specific embodiment, and in conjunction with the accompanying drawings the technical solution of the utility model is described in further detail.
Embodiment:
A kind of sleeve crank of present embodiment referring to Fig. 1, comprises socket bar 1, collet head 2, handgrip 3, and collet head 2 is fixedly connected on an end of socket bar 1, and handgrip 3 is movably connected in the other end of socket bar 1; Socket bar 1 is " several " font, is provided with anti-skidding striped on the surface of handgrip 3.
Referring to Fig. 2, the end that socket bar 1 is connected with handgrip 3 has interior hexagonal interface 6, and handgrip 3 flexibly connects by jockey and socket bar 1, and jockey comprises connector 4, bearing 5; Connector 4 is made by round steel, and an end of connector 4 is hexahedrons, and the other end of connector 4 is the less small cylinders of a diameter; Hexahedron and interface 6 coincide, inner ring 8 tight fits of small cylinder and bearing 5, the outer ring 7 of bearing 5 and inwall 9 tight fits of handgrip 3.
Above embodiment is one of preferred plan of the present utility model, is not that the utility model is done any pro forma restriction, also has other variant and remodeling under the prerequisite that does not exceed the technical scheme that claim puts down in writing.
