Description

A hexagonal inner triangular bolt

technical field

The utility model relates to the field of fasteners, in particular to a hexagonal hexagonal inner triangular bolt.

Background technique

In the traditional mechanical equipment industry, large and small bolts in fasteners are the most common and commonly used standard parts, especially the outer hexagonal bolts, which are used in a very large amount and have a wide range of applications. However, in today's ever-changing mechanical equipment, ordinary fasteners and bolts can no longer meet the needs of many occasions, especially in some special equipment occasions, the role of ordinary fasteners and bolts is greatly restricted. Especially for ordinary hex bolts, after repeated disassembly by ordinary wrenches, the outer hexagon will be easily worn, so that the hexagon bolts become rounded bolts, and the rounded bolts lose their fasteners at all. Not only the bolts are scrapped, but also some equipment structures cannot be installed and disassembled, which brings great inconvenience to the actual production; Bring great inconvenience and waste.

Contents of the invention

The technical problem to be solved by the utility model is to provide a triangular bolt with a hexagonal shape and an internal shape, so that the bolt can achieve the maximum use effect.

The technical scheme adopted by the utility model to solve the technical problem is: provide a hexagonal shape triangular-shaped bolt, including a bolt head and a bolt neck connected to the bolt head; the lower end of the bolt neck has Bolt threads, the head of the bolt is in the shape of an external hexagon, and there is a triangular groove in the center of the end face.

The triangular grooves are regular triangular grooves.

Beneficial effect

Due to the adoption of the above-mentioned technical scheme, the utility model has the following advantages and positive effects compared with the prior art: the utility model makes full use of the shape of the hexagonal triangle formed on the top of the bolt, thereby greatly increasing the use effect of the bolt , not only can be installed and disassembled with ordinary wrenches and sockets, but also can be installed and disassembled with special tools, and when the outer hexagon is worn and rounded, there can be other methods to actively make up for it, and the installation can be achieved smoothly and teardown effects.

Detailed ways

Below in conjunction with specific embodiment, further set forth the utility model. It should be understood that these embodiments are only used to illustrate the present utility model and are not intended to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by the appended claims of the application.

Example 1

As shown in Figures 1 and 2, a triangular-shaped bolt with a hexagonal shape includes a bolt head 2 and a bolt neck 3 connected to the bolt head 2; the lower end of the bolt neck 3 has a bolt thread 4 , the bolt head 2 is in the shape of an outer hexagon, and there is a triangular groove 1 in the center of the end face. Wherein, the triangular groove 1 is a regular triangular groove.

The bolt can be used in many mechanical equipment occasions like ordinary bolts, especially the special shape bolt with both inner and outer shape, which not only has the function and function of the outer hexagon bolt, but also has a concave inner triangle at the end of the bolt head as a positioning. The bolt is very convenient to use. Not only can ordinary wrench and socket be used to achieve the effect of the original standard bolt, but also under the condition of using special tools, when the special bolt is fastened and loosened, due to the influence of the outer hexagon and inner triangle It is not suitable to slip due to mutual restriction, especially in some special cases, if there is no special tool, the disassembly effect will be affected. In addition, when the outer hexagon wears and causes rounded corners, special tools can be used, such as the inner triangle positioning outer hexagon combination sleeve, which can easily disassemble and fasten the bolts. The inner ring at the top of the sleeve is hexagonal plum-shaped, and the center is Triangular columnar structure. Special bolts can be disassembled by several methods, including: special socket wrench, ordinary socket wrench, ring wrench, inner triangle wrench, etc., which can effectively disassemble the bolt, so that the bolt can achieve the maximum use effect , so that the bolt can play the greatest role in ordinary occasions and special occasions.

It is not difficult to find that the utility model can select a variety of tools to disassemble the bolts according to the situation at that time in various occasions without damaging the bolts, thereby prolonging the service life of the bolts, facilitating the disassembly work, and protecting resources. , time-saving and convenient to use.

Claims (2)

1. the interior shape triangular shape bolt of profile hexagonal comprises bolt head (2), the bolt neck (3) that links to each other with described bolt head (2); There is bolt thread (4) described bolt neck (3) lower end, it is characterized in that, described bolt head (2) is the outer-hexagonal shape, and there is triangular groove (1) at its end face center.

2. shape triangular shape bolt in the profile hexagonal according to claim 1 is characterized in that described triangular groove (1) is the equilateral triangle groove.
