技术领域technical field
本实用新型属于螺栓技术领域，尤其涉及一种转轴螺栓。The utility model belongs to the technical field of bolts, in particular to a shaft bolt.
背景技术Background technique
螺栓属于一种紧固件，在各个领域当中都涉及使用，尤其是在机械领域中使用甚是频繁，螺栓一般由螺栓头和螺栓杆组成，现有的螺栓头一般都采用方形结构的螺栓头，如正四边形，正六边形；但这种这种方形结构螺栓头的螺栓使用受到很大的局限性，且安装不方便，在缺少扳手等工具的情况下就不易拧紧或松开；而且这种结构的螺栓在安装时碰到表面不平整是很难拧紧固定，容易松动脱落。The bolt belongs to a kind of fastener, which is used in various fields, especially in the mechanical field. The bolt is generally composed of a bolt head and a bolt shaft. The existing bolt heads generally adopt square structure bolt heads. , such as regular quadrilateral, regular hexagonal; but the use of bolts with this square structure bolt head is greatly limited, and the installation is inconvenient, and it is not easy to tighten or loosen without tools such as wrenches; and this Bolts of this structure are difficult to tighten and fix when they encounter uneven surfaces during installation, and they are easy to loosen and fall off.
实用新型内容Utility model content
本实用新型的目的是提供一种安装方便、不易松动的转轴螺栓。The purpose of the utility model is to provide a shaft bolt which is easy to install and not easy to loosen.
本实用新型的目的是这样实现的：The purpose of this utility model is achieved in that:
转轴螺栓，包括螺栓头和成型在螺栓头上的螺栓杆，螺栓杆居中设置在螺栓头上，螺栓杆包括螺纹部以及光杆部，所述螺栓头的纵截面为半圆形。The shaft bolt includes a bolt head and a bolt shaft formed on the bolt head. The bolt shaft is centrally arranged on the bolt head. The bolt shaft includes a threaded part and a polished shaft part. The longitudinal section of the bolt head is semicircular.
上述半圆形的螺栓头的弧面面向螺栓杆一侧，螺栓杆上的光杆部位于靠螺栓头的一侧。The arc surface of the semicircular bolt head faces one side of the bolt shaft, and the polished part of the bolt shaft is located at the side close to the bolt head.
上述螺纹部的端头倒角设置。The end chamfering of the threaded portion is provided.
上述螺栓头的横截面为矩形。The cross-section of the above-mentioned bolt head is rectangular.
上述螺纹杆上的螺纹部的直径与光杆部的直径相等，螺纹杆的直径小于或等于螺栓头的宽度。The diameter of the threaded portion on the threaded rod is equal to the diameter of the polished rod, and the diameter of the threaded rod is smaller than or equal to the width of the bolt head.
本实用新型相比现有技术突出且有益的技术效果是：Compared with the prior art, the utility model has outstanding and beneficial technical effects as follows:
1、本实用新型螺栓头采用半圆结构，使螺栓安装更用容易拧紧固定,而且不易松动脱落。1. The bolt head of the utility model adopts a semicircular structure, which makes the bolt installation easier to tighten and fix, and is not easy to loosen and fall off.
2、本实用新型在一些扳手不易使用或缺少扳手等工具的情况下，也能用手拧紧或者松开，安装方便。2. The utility model can also be tightened or loosened by hand when some wrenches are not easy to use or tools such as wrenches are lacking, and the installation is convenient.

具体实施方式detailed description
下面结合附图以具体实施例对本实用新型作进一步描述，参见图1—图3：The utility model will be further described below in conjunction with the accompanying drawings with specific embodiments, referring to Fig. 1-Fig. 3:
转轴螺栓，包括螺栓头1和成型在螺栓头1上的螺栓杆2，螺栓杆2居中设置在螺栓头上，螺栓杆2包括螺纹部4以及光杆部3，所述螺栓头1的纵截面为半圆形、横截面为矩形；采用这种半圆形结构的螺栓头，在配合螺母拧紧时的固定效果更好，且可以在无法使用扳手的环境中或者缺少扳手等工具的情况下用手拧紧或松开；上述半圆形的螺栓头1的弧面5面向螺栓杆2一侧，螺栓杆2上的光杆部3位于靠螺栓头1的一侧。The shaft bolt includes a bolt head 1 and a bolt shank 2 formed on the bolt head 1. The bolt shank 2 is centrally arranged on the bolt head. The bolt shank 2 includes a threaded part 4 and a polished shank part 3. The longitudinal section of the bolt head 1 is Semi-circular and rectangular in cross-section; the bolt head with this semi-circular structure has a better fixing effect when the mating nut is tightened, and it can be used in an environment where a wrench cannot be used or when tools such as a wrench are lacking. Tighten or loosen; the arc surface 5 of the above-mentioned semicircular bolt head 1 faces the side of the bolt shank 2 , and the polished rod portion 3 on the bolt shank 2 is located on the side close to the bolt head 1 .
上述螺纹部4的端头倒角设置，倒角的设计使得螺纹部的直径略小于螺纹部的直径，方便螺母的拧入，倒角还可以避免螺纹部端头在攻丝后留下毛刺。The end of the threaded part 4 is chamfered. The design of the chamfer makes the diameter of the threaded part slightly smaller than the diameter of the threaded part, which is convenient for screwing in the nut. The chamfering can also avoid burrs left on the end of the threaded part after tapping.
上述螺纹杆2上的螺纹部4的直径与光杆部3的直径相等，螺纹杆2的直径R小于或等于螺栓头1的宽度W。The diameter of the threaded portion 4 on the threaded rod 2 is equal to the diameter of the polished rod portion 3 , and the diameter R of the threaded rod 2 is less than or equal to the width W of the bolt head 1 .
上述实施例仅为本实用新型的较佳实施例，并非依此限制本实用新型的保护范围，故：凡依本实用新型的结构、形状、原理所做的等效变 化，均应涵盖于本实用新型的保护范围之内。The foregoing embodiments are only preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore: all equivalent changes made according to the structure, shape, and principle of the present utility model should be covered by this utility model. within the scope of protection of utility models.
