Description

A kind of bendable torque wrench

Technical field

The utility model is related to a kind of bendable torque wrench, belongs to torque wrench technical field.

Background technology

Torque wrench is called torque spanner, torque spanner, moment of torsion adjustable spanner, is that maintenance of equipment and processing are assembled in industry Essential instrument, is used to tighten various bolts, it is ensured that the positive connection of plant equipment and normally use.Torque wrench is pressed Power source can be divided into electrokinetic moment spanner, pneumatic torque wrench, hydraulic torque spanner and manual torque spanner；Wherein manual torque Spanner can be divided into presetting system, constant value type, dial type, digital display type, slipping type, bendable and kilogram spanner.

At present, structure design not reasonableization of existing bendable torque wrench, profile is common, and moulding is not novel only enough Spy, volume is larger, compares space-consuming, complex operation, uses extremely inconvenient, and the scope of application compares limitation, it is impossible to pass through Intuitively visual alerts or warning operator's instrument behaviour in service, can not meet the use demand of people.

The content of the invention

In view of the above-mentioned problems, the technical problems to be solved in the utility model is to provide a kind of bendable torque wrench.

A kind of bendable torque wrench of the present utility model, it includes square toes, wrench body, knurled nut, spring, spiral shell Bar, handle grips, steady pin, rivet, square toes are plugged in the ratchet head bore of wrench body, and one end of knurled nut passes through several Spring is fixedly connected with one end of screw rod, and handle grips pass through the screw rod with spring and knurled nut to pass through steady pin and rivet It is fixedly connected with one end of wrench body.

The beneficial effects of the utility model：Its reasonable in design, low-profile, installation operation is simple, easy to use, when When reaching setting value, wrench body part occurs bending, even operator, which continues to exert a force, can also reduce overload in certain limit Possibility, it is adaptable to the noisy occasion in working site, can remind or alert operator's instrument by intuitively vision Behaviour in service.

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- wrench bodies；3- knurled nuts；4- springs；5- screw rods；6- handle grips；7- steady pins；8- rivets.

Embodiment：

As shown in figure 1, present embodiment uses following technical scheme：It includes square toes 1, wrench body 2, scale spiral shell Mother 3, spring 4, screw rod 5, handle grips 6, steady pin 7, rivet 8, square toes 1 are plugged in the ratchet head bore of wrench body 2, scale One end of nut 3 is fixedly connected by several springs 4 with one end of screw rod 5, and handle grips 6, which are passed through, carries spring 4 and scale spiral shell The screw rod 5 of mother 3 is fixedly connected by steady pin 7 and rivet 8 with one end of wrench body 2.

The use principle of present embodiment：First, knurled nut 3 is rotated to the target needed to client as needed Value, will carry out pressure regulation in the rotary course of knurled nut 3 to spring 4, the stress of spanner operationally spring 4, lead Cause the torque value of spanner final output can be consistent with the torque value on knurled nut 3；Then, the input square toes 1 of bending wrench, lead to The target bolt that standard cartridges connection needs to tighten is crossed, now square toes 1 are inserted into the ratchet head bore of wrench body 2；Finally, hand is used Catch and steadily exerted a force on the handle grips 6 of bending wrench, because the handle grips 6 of now spanner have passed through band spring 4 and scale The screw rod 5 of nut 3, the body 2 and handle grips 6 of spanner are constituted into one by steady pin 7 and rivet 8 can be 3 turns around steady pin Dynamic linkage, the handle grips 6 of spanner will rotate around steady pin 3, and bending phenomenon occurs for wrench body 2；Work as operator It was observed that after the obvious bending of spanner, stopping 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.

Present embodiment reasonable in design, low-profile, installation operation is simple, easy to use, is set when reaching During value, wrench body part occurs bending, even operator, which continues to exert a force, can also reduce the possibility of overload in certain limit, Suitable for the occasion that working site is noisy, the behaviour in service of operator's instrument can be reminded or alerted by intuitively vision.

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 is 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 appended claims and its equivalent thereof.
