Abstract
The utility model discloses a torque wrench. The wrench comprises a connecting pipe, a wrench head arranged at the front part of the connecting pipe and two handle levers which are arranged on the connecting pipe and can drive the connecting pipe to rotate around the shaft axis, wherein two arc-shaped plates formed by separating two symmetrical notches on the connecting pipe are arranged in the front of the connecting pipe; and the wrench head consists of the two arc-shaped plates and connection plates respectively arranged between the side walls of the two notches. The torque wrench has the characteristics that the structure is simple, the price is low and the operation is convenient; the working efficiency is improved and the labor intensity is reduced; the weight is light and firmness and durability are achieved; and the security is excellent, so that the probability of personal injury is low.
Description
Technical field
The utility model relates to a kind of hardware ﹠ tools, especially relates to a kind ofly can effectively having improved operating efficiency, has reduced the torque spanner of labour intensity.
Background technology
Device category in factory is various, complex structure, and the lifting nut size of main equipment is larger, needs to use torque spanner that the lifting nut is dismantled and installed.Common torque spanner structure is complicated, and operation inconvenience is expensive.During the lifting nut of installing/dismounting " annular " or " butterfly ", be to adopt the light instrument such as metal bar to carry out installation or removal in common factory, metal bar penetrated in the ring of lifting nut, then the both hands rotating metallic rod of exerting oneself, make the lifting nut rotation.Usually need to repeatedly take off, insert metal bar and just can complete dismounting and the installation of a lifting nut, cause operating efficiency very low.
Chinese patent Granted publication CN201922392U discloses a kind of torque spanner August 10 2011 Granted publication day, and its mechanical part comprises rotary head, gets rid of head, motor, lithium battery, casing, positive and negative switch, bonnet, cradle.Get rid of head and be connected with motor, rotary head is enclosed within the outer ring of getting rid of head, and positive and negative switch one end is connected with motor, and the other end is connected with lithium battery, and the below of lithium battery is designed with a cradle, and there is a bonnet outside of cradle.The weak point of this utility model is expensive, operation inconvenience.
The utility model content
The utility model is expensive in order to overcome torque spanner of the prior art, unhandy deficiency, and providing a kind of can effectively improve operating efficiency, has reduced the torque spanner of labour intensity.
To achieve these goals, the utility model is by the following technical solutions:
A kind of torque spanner, described spanner comprise tube connector, be located at the driving end of tube connector front portion and be located at driven tube connector on tube connector around two handlebars of the axial line rotation of tube connector; The tube connector front portion is provided with by being located at the symmetrical breach of on tube connector two separates two arcs that consist of, and described driving end is made of two arcs and the connecting plate be located at respectively between the sidewall of two breach.
Spanner of the present utility model is applicable to install, dismantle the lifting nut of main equipment, and is little with metal bar phase specific volume, can rotate by 360 degree, easy to operate; Compare simple in structure, low price, easy to operate with torque spanner of the prior art.Both save expense, improved again operating efficiency.
Use procedure of the present utility model is as follows:
When screwing up with a wrench the lifting nut, the boss of breach with the lifting nut fastened, two handlebars of then with the hands holding with a firm grip respectively turn clockwise, and driving end will lift nut screwing clamping;
During with spanner dismounting lifting nut, the lifting nut of the main equipment of needs dismounting is put in breach, both hands two handlebars of holding with a firm grip respectively firmly are rotated counterclockwise, and the lifting nut is unscrewed and disassembles.
Both hands firmly operation simultaneously is convenient in the design of the structure of handlebar, stress equalization on spanner, and spanner and lifting nut are not fragile; And spanner is difficult for breaking away from the lifting nut, can not cause because of operate miss personal injury.Two hands are exerted oneself together, and rotation is got up more laborsaving.
The structure of driving end is convenient to the lifting nut is blocked, and can not slide during rotation.The structure of tube connector makes this spanner quality light, rapid operation.
As preferably, described breach is opening U-shaped forward.
The setting of U-shaped breach makes the size of the lifting nut that driving end can block that scope more widely be arranged.One end of the nut that size is slightly large can enter in the U-shaped breach.
As preferably, described connecting plate is rectangle, and connecting plate is positioned at the leading edge of the rear of notch tip and connecting plate apart from 1 centimetre to 2.5 centimetres of notch tip.
The leading edge of connecting plate is apart from the restriction of 1 centimetre to 2.5 centimetres of notch tip, makes the driving end front portion can not form with the lifting nut and interferes, and compounding practice is convenient.
As preferably, the cross section of described handlebar is circular, and the axial line of two handlebars coincides.
As preferably, the outer surface of described handlebar is provided with screw thread.
Arranging of screw thread on the outer surface of handlebar can prevent that effectively in operating process, hand skids.
As the replacement scheme of such scheme, described handlebar is provided with taper knob, and taper knob is provided with wavy surface.
Taper knob the grasping that facilitates hand is set, the setting of wavy surface matches with the shape of hand, hand is difficult for skidding, and more comfortable.
As preferably, the cross section of tube connector is circular.
As preferably, handlebar is located at the tube connector middle part.It is more laborsaving when the position of handlebar setting makes hand operated.
Therefore, the utlity model has following beneficial effect: (1) is simple in structure, low price, easy to operate; (2) improve operating efficiency, reduced labour intensity; (3) quality is light, sturdy and durable; (4) security is good, is difficult for causing personal injury.
