Description

Fixed-force socket wrench for disassembling and assembling storage battery

Technical Field

The utility model relates to a set of spanner technical field specifically is a fixed force box spanner of dismouting battery.

Background

The socket wrench is generally composed of a plurality of sockets and a plurality of accessories such as a handle and a connecting rod, and is particularly suitable for screwing bolts or nuts with very narrow or deep sunken positions. The storage battery is usually installed in the engine compartment, some spare tires are installed in the trunk, the bolt is limited by space, and the nut end or the bolt end is mostly lower than the connected surface, so that the storage battery is usually disassembled and assembled by using a socket wrench.

When the socket wrench is used, a socket completely attached to a nut or a bolt is selected, the handle is connected with the socket wrench to roll, the bolt and the nut are loosened or screwed through rotating torque, if the force is too large in the using process, the rotating torque exceeds the bearing range of the nut or the bolt, the nut or the bolt is easily damaged, and the socket wrench has the requirement on the size of the acting force, so that the fixed-force socket wrench appears in the market.

However, the fixed-force socket wrench of current adopts the sleeve of fixed specification mostly, because the specification and the size of nut and bolt are many, consequently in the use, need carry the sleeve of multiple different specifications, there may be the condition of carrying and awkward, some fixed-force socket wrench adopts universal sleeve in addition, because adopt a lot of telescopic rod irons in the universal sleeve, because the rod iron size is little and independent each other, in the use, it is inconvenient probably to have the setting, the effort to nut and bolt transmission is unstable, lead to the atress to be little, the unbalanced problem.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a definite force box spanner of dismouting battery, in order to solve prior art, the box spanner of deciding the strength adopts the sleeve of fixed specification mostly, because the specification and the size of nut and bolt are many, consequently in the use, need carry the sleeve of multiple different specifications, there may be the condition of carrying and awkward, partial box spanner of deciding the strength adopts omnipotent sleeve in addition, because adopt a lot of telescopic rod irons in the omnipotent sleeve, because the rod iron size is little and independent each other, in the use, it is inconvenient to probably have the setting, the effort to nut and bolt transmission is unstable, lead to the atress on the small side, unbalanced problem.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a definite force box spanner of dismouting battery, includes the sleeve, and telescopic top is equipped with the U-shaped fixed block, and U-shaped fixed block top is equipped with the loop bar, and telescopic inside is equipped with the concave hexagon sleeve of a plurality of different specifications respectively, is equipped with the spring between every concave hexagon sleeve and the U-shaped fixed block.

Preferably, the bottom of the loop bar is provided with a convex block matched with the U-shaped fixed block, and one side of the U-shaped fixed block is provided with a pin shaft which penetrates through the convex block and extends to the other side.

Preferably, the top of the sleeve is symmetrically provided with a plurality of screws extending into the U-shaped fixing block.

Preferably, the loop bar is in threaded connection with a screw, and the top of the screw is provided with a joint.

Preferably, the opposite surfaces of the loop bar and the joint are provided with round corners.

The utility model discloses possess following beneficial effect at least:

after the sleeve is contacted with the nut and the bolt, because the nut and the bolt have different sizes and specifications, when the sizes of the nut and the bolt are larger than the concave hexagonal sleeve with the minimum specification, the corner of the nut and the bolt can push the small concave hexagonal sleeve to move upwards in the downward movement process of the sleeve, the concave hexagonal sleeve with the corresponding specification can be completely attached to the nut and the bolt, thereby loosening or screwing the nut and the bolt, compared with the prior art, most of fixed-force sleeve wrenches adopt the sleeve with fixed specification, because the specifications and the sizes of the nut and the bolt are more, in the use process, the sleeves with different specifications need to be carried, the condition of inconvenient carrying and use can exist, and because the universal sleeve adopts a plurality of telescopic steel bars, because the steel bars have small sizes and are independent, in the use, probably there is the setting inconvenient, and the effort to the nut and bolt transmission is unstable, leads to the atress to be on the small side, unbalanced problem, and this scheme can be applicable to loosen and tighten the nut and the bolt of different sizes and specification, and conveniently sets, can stabilize the atress, guarantees that the atress is balanced.
