Description

Novel wrench

Technical Field

The utility model belongs to the technical field of mechanical tool, concretely relates to novel spanner for lock bullet machine installation and dismantlement.

Background

The wrench is a common mounting and dismounting tool, and is a hand tool for screwing bolts, screws, nuts and other threads or opening or trepanning fasteners of the nuts by utilizing the lever principle; the wrench is usually made of structural steel made of carbon or alloy materials, an opening or a trepanning for clamping a bolt or a nut is usually formed at one end or two ends of a handle part, when the wrench is used, external force is applied to the handle part along the rotation direction of a thread, the bolt or the nut can be screwed, and the manual wrench is also called as a common wrench and is mainly applied to common life and work.

In the process of installing or disassembling the bullet locking machine, due to the limitation of the positions of bolts or nuts to be partially installed or disassembled, the bullet locking machine needs to be manually disassembled and assembled, but the opening angle and the handle length of the existing common wrench are not matched with the positions, so that the bullet locking machine cannot be used; and adopt other small-size instrument assistance also can be because of not adaptation, lead to the operation to be hard and trivial details, efficiency is lower, must dismantle the pipe of operation department even, installs the pipe in the future and can have airtight hidden danger.

Therefore, it is necessary to design a new type of wrench for equipment with limited working space, such as a bullet-locking machine.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve current spanner in the use, often can lead to unable installation or dismantlement to be located the weak point of the bolt or the nut of position limitation because of the problem of the not looks adaptation of opening angle, handle length, and provide a novel spanner.

In order to achieve the above object, the present invention provides a technical solution:

a novel wrench is characterized in that: comprises a first wrench head, a handle and a second wrench head which are positioned on the same plane and connected in sequence;

the handle is in a right trapezoid shape, the small end of the handle is connected with the second wrench head, the size L of the joint is 17 +/-1 mm,

the opening directions of the first wrench head and the second wrench head are positioned at the same side of the central line of the handle, and the included angles between the central line of the openings and the central line of the handle are both 30 +/-3 degrees;

the part of the second wrench head, which is close to the handle and is positioned at the side of the opening direction, is provided with a radian with the radius of 20 +/-2 mm.

Furthermore, in order to work in a limited space with half the effort and save effort and improve the dismounting efficiency, the size L of the connecting part is 17mm; the included angles between the central lines of the openings of the first wrench head and the second wrench head and the central line of the handle are both 30 degrees; the part of the second wrench head, which is close to the handle and is positioned at the side of the opening direction, is provided with a radian with the radius of 20 mm.

Further, the opening shapes of the first wrench head and the second wrench head are suitable for the hexagonal fastener.

Further, the opening of the first wrench head is 42mm; the opening of the first wrench head is 48mm.

Of course, the shape and size of the first and second wrench openings may be adjusted accordingly according to the frequently used scenario.

Furthermore, in order to reduce the cost and prolong the service life, the material is 40Gr with wide sources.

The utility model has the advantages that:

the wrench of the utility model is simple in structure, but the effect is excellent, and the operation time is shortened by 70% when the same operation is carried out; when carrying out the dismouting to the lock bullet machine, can avoid the bulkhead and the pipe of operation department, make spanner rotation angle increase, reduce unnecessary process and avoid because of dismantling the unable guarantee hidden danger of airtight that the pipe caused, have good application prospect, solve present spanner in the use, often can be because of the problem of the not looks adaptation of opening angle, handle length.

The reference numbers are as follows:

1-a first wrench head, 2-a second wrench head and 3-a handle.

Detailed Description

The invention is described in further detail below with reference to the following figures and specific examples:

as shown in fig. 1, a novel wrench is mainly applied to the disassembly and assembly of a bullet locking machine, and comprises a first wrench head, a handle and a second wrench head which are positioned on the same plane and connected in sequence; the handle is in a right trapezoid shape, the small end of the handle is connected with the second wrench head, the size L of the connection part is 17 +/-1 mm, the opening directions of the first wrench head and the second wrench head are positioned at the same side of the central line of the handle, and the included angles (a and b) between the central line of the opening and the central line of the handle are both 30 +/-3 degrees; the part of the second wrench head, which is positioned at the side of the opening direction and close to the handle, is provided with a radian with the radius R of 20 +/-2 mm. In order to achieve the purpose of achieving double results with half effort and saving labor and improving the disassembling and assembling efficiency when the locking bomb machine is disassembled and assembled in a limited space, the size L of a connecting part is 17mm; the included angles between the central lines of the openings of the first wrench head and the second wrench head and the central line of the handle are both 30 degrees so as to avoid a side conduit of the bullet locking machine; the part of the second wrench head, which is close to the handle and is positioned at the side of the opening direction, is provided with a radian with the radius of 20 mm; the opening shapes of the first wrench head and the second wrench head are both suitable for the hexagonal fastener; the opening width of the first wrench head is 42mm; the opening width of the second wrench head is 48mm. In order to reduce the cost and prolong the service life, the material is 40Gr with wide sources.

This novel spanner can avoid the bulkhead and the pipe of installation department when using, makes spanner rotation angle increase, solves present spanner in the use, often can be because of the problem of the not looks adaptation of opening angle, handle length.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of various equivalent modifications or replacements within the technical scope of the present invention, and these modifications or replacements should be covered within the protection scope of the present invention.
