Abstract
The utility model relates to a torque spanner, which respectively combines a ratchet wheel arm and a torque force regulator respectively with two ends of a steel tube of the torque spanner. Wherein, the ratchet wheel arm is provided with a ratchet wheel head. The torque force regulator is arranged with a handle spliced with a steel tube end. An end of the handle is extended to form a circular expansion part of larger diameter. The expansion part is formed with an unshaped groove covered by an amplifying lens. A bottom of the unshaped grove is axially extended to form scaled a flange to match an expansion arch surface. An expansion part of the handle combines with a knob. The knob is extended and provided with an index head with circumferential graduation marks towards the handle end. The index head can achieve interlinked adjustment of given torque force for the ratchet wheel arm and utilize structure characteristics as above to eliminate difficulty in reading set torque force of torque spanners, much time on adjustment and other defects.
Description
Affiliated technical field
The utility model relates to a kind of torque spanner, refers to the easily quick and easy torque spanner of the accurate interpretation of torsion setting scale of a kind of adjustment especially.
Background technology
Bolt and nut are on the group of machinery is upright; occupy considerable status always; but both can't unify because of operator carelessness or Fastening device error in conjunction with torsion regular meeting; for avoiding influencing whole mechanical structures integrality because of the bond strength deficiency of bolt and nut; therefore between the two truly have necessity of check in conjunction with torsion, and test the torsion most convenient rapidly method promptly be to use torque spanner.
Therefore, just the someone develops No. 295, the seven or seven 211 of application " bilateral sound equipment torque spanner structure improvement ", this case is except that the roller mount with general torque spanner is improved, wherein Zui Da change is reading of torsion adjusting device and setting value, it mainly is that the scale of torque value is located on the outer peripheral edges of knob, and on handle, establish a graduation mark, the pairing data of this graduation mark are the setting value of torque spanner, because this case has been improved the shortcoming of general torque spanner really, therefore the novel patent of approved, and be the one one four seven three nine-day periods after the winter solstice patent through bulletin.
Yet still there are some disappearances in it in the use of reality, can keep on improving more, for example, this torque spanner is all concentrated all scales and is located on the periphery of knob, it is very little that the distance of feasible graduation mark in twos becomes, and therefore is difficult for interpretation, causes erroneous judgement easily.
Content of the present utility model
Main purpose of the present utility model is providing a kind of easy and rapid certain torque spanner of adjustment of interpretation that sets value.
Based on above-mentioned purpose, the utility model mainly is an expansion mouth of establishing the big footpath of a tool in the part that handle extends steel pipe, this expansion mouth is to be formed with a short slot that is covered with magnifying glass, the bottom of this short slot is the flange that extends axially a cooperation expansion mouth cambered surface, on this flange and be formed with an axial graduation mark, an and knob that is hubbed at the handle expansion mouth, this knob is to extend axially to be formed with the one division head towards the one side of handle, be to be formed with equidistant graduation mark on the periphery of this dividing head, and the column axial restraint of driving screw is inserted in this dividing head.
Therefore, as long as the rotation knob can drive driving screw and the guide screw piece is adjusted the torque settings of torque spanner, and only need confirm that handle flange high scale line points to the data on the dividing head, can easily judge torque settings.
Below in conjunction with drawings and Examples the utility model is done detailed description further:
Description of drawings
Fig. 1 is the stereo appearance figure that the utility model combines with torque spanner.
Fig. 2 is the three-dimensional exploded view that the utility model cooperates torque spanner.
The fragmentary cross-sectional view that Fig. 3 the utility model combines with torque spanner.
Specific embodiment
See also as shown in Figure 1, 2, 3, the torque spanner of primary structure of the present utility model and above-mentioned the one one four seven three nine-day periods after the winter solstice of bulletin patent is roughly the same, it mainly is to comprise a steel pipe 10, be to be inserted with an arm of ratchet 11 in one end of this steel pipe 10, its other end then is equiped with a torsion adjusting device 20, the end that this arm of ratchet 11 extends steel pipe is to be ratchet head that can sheathed sleeve, and its end that is arranged in steel pipe is that the top is provided with a roller mount, be primarily characterized in that this torsion adjusting device 20 is to comprise:
One is sheathed on the handle 21 of steel pipe 10 ends, the part that this handle 21 extends steel pipe 10 is the expansion mouth 210 that forms the big footpath of a tool, this expansion mouth 210 is to be formed with a short slot 211, the bottom of this short slot 21 1 is to extend axially a flange 212 that cooperates expansion mouth 210 cambered surfaces, on this flange 212 and be formed with an axial graduation mark 213;
One is covered on the lens 22 in handle 21 short slots 211, can read setting value more like a cork for making the user, and these lens 22 are to be a magnifying glass; And
One is hubbed at the knob 23 of handle 21 expansion mouths 210, and this knob 23 is to extend axially to be formed with one division head 231 towards the one side of handle, is to be formed with equidistant graduation mark on the periphery of this dividing head 231;
One wears the driving screw 24 that is incorporated into knob 23, and an end of this driving screw 24 is axially to plug in the dividing head 231 that is linked to this knob 23, forms the externally threaded spiro rod section 241 of a tool in the other end;
One sheathed be incorporated into driving screw 24 set spiro rod sections 241 push away post 25, this end that pushes away post 25 forms the tube seat 251 of tool internal thread, this tube seat 251 is with sheathed set spiro rod section 241 outsides of driving screw 24 that are incorporated into of internal and external screw thread fit system;
One is located at the torque spring 26 that pushes away between post 25 and the roller mount 27 with elastic force top.
So,, change the strength that torque spring 26 is resisted against roller mount 27, and then adjust the torque settings of torque spanner as long as rotation knob 23 can drive driving screw 25 and push away post 25.
Be front described, the utility model has lower several characteristics really:
1, the torque settings of spanner reads easily, only needs to confirm handle 21 flanges 212 high scale lines 21 3 point to the data on the dividing head 231, can easily judge torque settings.
2, because all data are all delineated on dividing head 231, therefore only need 23 1 weeks of rotation knob namely The torque settings of torque spanner can be transferred to maximum by minimum, or maximum transfers to minimum, so have torsion setting Value is adjusted rapidly certain advantage.
If 3 because of the scale on the big dividing head 231 of the scope of application of torque spanner when closeer, the user can be saturating Cross magnifying glass 22 and come interpretation data, do not have the situation of erroneous judgement.
