Description
技术领域 technical field
本实用新型涉及一种防松螺栓。 The utility model relates to an anti-loosening bolt.
背景技术 Background technique
螺栓为日常生活中不可或缺的工业必需品，在工业上也负有重要的任务，普通的螺栓在使用过程中极易因外界的原因发生松动，给工业制造和工业产品的致命隐患。 Bolts are an indispensable industrial necessity in daily life, and also have important tasks in industry. Ordinary bolts are very easy to loosen due to external reasons during use, which poses a fatal hidden danger to industrial manufacturing and industrial products.
实用新型内容 Utility model content
鉴于背景技术存在的不足，本实用新型所要解决的技术问题是提供一种结构简单、防松效果好的防松螺栓。 In view of the deficiencies in the background technology, the technical problem to be solved by the utility model is to provide an anti-loosening bolt with a simple structure and good anti-loosening effect.
本实用新型是采取如下技术方案来完成的：一种防松螺栓，其螺杆包括头部和杆部，杆部设有外螺纹，所述外螺纹包括第一螺纹牙和第二螺纹牙，所述第一螺纹牙和第二螺纹牙间隔排列，第二螺纹牙与第一螺纹牙的角度偏差为9°，所述杆部与头部下表面固定连接，所述头部下表面设有若干防松凸起。 The utility model is completed by adopting the following technical scheme: a kind of anti-loosening bolt. The first thread teeth and the second thread teeth are arranged at intervals, the angle deviation between the second thread teeth and the first thread teeth is 9°, the rod part is fixedly connected with the lower surface of the head, and the lower surface of the head is provided with several Anti-loose bumps.
所述防松凸起由杆部向外延伸至头部下表面的边缘，所述防松凸起为的三角形。 The anti-loosening protrusion extends outward from the stem to the edge of the lower surface of the head, and the anti-loosening protrusion is in the shape of a triangle.
本实用新型中，该防松螺栓结构简单，在螺栓拧紧时第二螺纹牙会破坏掉与之配合的内螺纹，使内螺纹被迫改变形状从而达到防松的效果，头部下表面的防松凸能够提高螺栓锁紧后产生回退是的阻力，从而加强螺栓的防松效果。 In the utility model, the anti-loosening bolt has a simple structure. When the bolt is tightened, the second thread tooth will destroy the internal thread matched with it, so that the internal thread is forced to change its shape to achieve the effect of anti-loosening. The anti-loosening effect of the lower surface of the head Loose protrusions can increase the resistance of the bolts to retreat after they are locked, thereby enhancing the anti-loosening effect of the bolts.

具体实施方式 detailed description
附图表示了本实用新型的技术方案及其实施例，下面再结合附图进一步描述其实施例的各有关细节及其工作原理。 The accompanying drawings show the technical solution of the utility model and its embodiments, and the details and working principles of the embodiments will be further described below in conjunction with the accompanying drawings.
参照图1、图2所示，本实用新型提供的一种防松螺栓，包括头部1和杆部2，所述杆部2设有外螺纹3，所述外螺纹3包括第一螺纹牙4和第二螺纹牙5，所述第一螺纹牙4和第二螺纹牙5间隔排列，第二螺纹牙5与第一螺纹牙4的角度偏差为9°，以图2为例具体结构为：在每颗牙的下一颗出现如图2所示的直径相同、角度偏差为9°的异型牙，为1/4圈，然后为一圈正常牙，接着再接1/4圈异型牙，以此类推，应用于牙数最少为八颗牙的螺栓上。所述杆部2与头部1下表面固定连接，所述头部下表面6设有若干防松凸起7，所述防松凸起7由杆部2向外延伸至头部下表面6的边缘，所述防松凸起7为的三角形。 Referring to Fig. 1 and Fig. 2, a kind of anti-loosening bolt provided by the utility model includes a head 1 and a stem 2, and the stem 2 is provided with an external thread 3, and the external thread 3 includes a first thread thread 4 and the second thread teeth 5, the first thread teeth 4 and the second thread teeth 5 are arranged at intervals, and the angle deviation between the second thread teeth 5 and the first thread teeth 4 is 9°. Taking Fig. 2 as an example, the specific structure is : A special-shaped tooth with the same diameter and an angle deviation of 9° appears next to each tooth, as shown in Figure 2, which is 1/4 circle, then a circle of normal teeth, and then 1/4 circle of special-shaped teeth , and so on, applied to bolts with at least eight teeth. The rod 2 is fixedly connected to the lower surface of the head 1, and the lower surface 6 of the head is provided with several anti-loosening protrusions 7, and the anti-loosening protrusions 7 extend outward from the rod 2 to the lower surface 6 of the head. The edge of the anti-loosening protrusion 7 is a triangle.
