Description
Technical field
The utility model is related to a kind of manual torque spanner, belongs to manual wrench technical field.
Background technology
Manual wrench is called common wrench, is mainly used in common life and work, and its use is fairly simple, main point
For single head fork spanner, double ended spanner, monkey wrench, double offset ring spanner, combination wrench, percussion spanner, box spanner, sleeve rise
Son, torque spanner, torque wrench, wherein torque wrench are called torque spanner, torque spanner or moment of torsion adjustable spanner, manual torque
Spanner can be divided into presetting system, constant value type, dial type, digital display type, slipping type, bendable and kilogram spanner, and torque spanner is most main
It can be just setting moment of torsion to want feature, and moment of torsion is adjustable.
At present, structure design not reasonableization of existing manual torque spanner, volume is big, and weight is heavier, and operation is multiple
It is miscellaneous, use and not enough facilitate, the scope of application compares limitation, can not meet the use demand of people.
The content of the invention
Regarding to the issue above, the technical problems to be solved in the utility model is to provide a kind of manual torque spanner.
A kind of manual torque spanner of the present utility model, it comprising square toes, axle sleeve, wrench body, end cap, second lever,
Axle sleeve pad, spring, knurled nut, swivel bolt, bolt, location nut, adjusting knob, one end of square toes plug through axle sleeve
In the circular hole of wrench body one end, the spline connection on adjusting knob and swivel bolt one end, one end of swivel bolt passes through
Bolt and location nut are fixed in wrench body, and the other end and the knurled nut screw thread of swivel bolt are connected, and pass through
Spring and axle sleeve pad are fixed in wrench body, and the front end of wrench body is provided with second lever, the front end peace of second lever
Equipped with end cap.
The beneficial effects of the utility model：Its reasonable in design, low-profile is lightweight, simple to operate, user
Just, the sound or seismaesthesia for tapping the generation of wrench body tube wall by the second lever of spanner make to remind and alert operator's instrument
With situation, it is adaptable to which the narrow small moment of torsion of station tightens demand.
Brief description of the drawings：
For ease of explanation, the utility model is described in detail by following specific implementations and accompanying drawing.
Fig. 1 is structural representation of the present utility model.
1- square toes；2- axle sleeves；3- wrench bodies；4- end caps；5- second levers；6- axle sleeve pads；7- springs；8- scale spiral shells
It is female；9- swivel bolts；10- bolts；11- location nuts；12- adjusting knobs.
Specific embodiment：
As shown in figure 1, this specific embodiment uses following technical scheme：It comprising square toes 1, axle sleeve 2, wrench body 3,
End cap 4, second lever 5, axle sleeve pad 6, spring 7, knurled nut 8, swivel bolt 9, bolt 10, location nut 11, regulation rotation
Button 12, one end of square toes 1 is plugged in the circular hole of the one end of wrench body 3 through axle sleeve 2, adjusting knob 12 and swivel bolt 9 one
Spline connection on end, one end of swivel bolt 9 is fixed in wrench body 3 through bolt 10 and location nut 11, rotates spiral shell
The other end of bolt 9 is connected with the screw thread of knurled nut 8, and is fixed in wrench body 3 by spring 7 and axle sleeve pad 6, pulls
The front end of hand body 3 is provided with second lever 5, and the front end of second lever 5 is provided with end cap 4.
The operation principle of this specific embodiment：The target that rotation of adjustment knob 12 needs to client as needed first
Value, is rotated bolt 9 and rotates together during rotation of adjustment knob 12, then converted knurled nut 8 by the rotation of screw pair
Be linear motion, pressure regulation will be carried out to spring 7 in this linear motion, spanner operationally, the stress of spring 7,
Cause spanner final output torque value can and knurled nut 8 on torque value one to finally grasping behind wrench body 3
Arbitrfary point steadily exert a force, when reaching setting value, the second lever 5 of spanner taps the tube wall of wrench body 3 and sends the sound, until listening
To after reminding sound or feel to skid, stop continuing to exert a force immediately, then the screw-down torque now to target bolt is exactly to start to set
Fixed torque value, completion tightens operation to bolt.
The torque range that this specific embodiment is used is 1-5N.M or 10-50lbf.in or tri- kinds of rule of 10-50kgf.cm
Lattice, precision is ± 3%.
This specific embodiment reasonable in design, low-profile is lightweight, simple to operate, easy to use, by spanner
Second lever sound that wrench body tube wall occurs or seismaesthesia is tapped to remind and alert operator's instrument behaviour in service, be applicable
Demand is tightened in the narrow small moment of torsion of station.
General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the utility model spirit and scope are not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within the range of claimed the utility model.The utility model
Claimed scope is by appending claims and its equivalent thereof.
