Abstract

An anti-loosening anti-loosening nut, including a nut body, a small bolt and a rubber gasket, is characterized in that: bolt holes are provided on a pair of symmetrical sides of the nut and matching small bolts are added, and a rubber gasket is embedded in the inner end of the bolt hole The thread lead angle is 1.5°, and there is a cross groove on the top of the bolt head of the small bolt. When there is no small wrench, it can be screwed in with a screwdriver, which is convenient for use. When in use, after positioning the nut, screw in the small bolt, the bottom of the small bolt will be on the rubber gasket, so that the rubber gasket will be deformed and filled into the gap between the nut and its matching bolts, increasing the gap between them. The friction force can prevent loosening and falling off.

Description

Anti-loosening anti-loosening nut

技术领域 technical field

本实用新型涉及紧固件技术领域，具体说是一种防松防脱螺母。 The utility model relates to the technical field of fasteners, in particular to an anti-loosening anti-loosening nut. the

背景技术 Background technique

螺纹连接是常见的机械连接之一，而螺母在大多数螺纹连接中又是必不可少的一部分，由于机械的振动使得这一连接容易出现松脱，从而使振动加剧产生噪声而且会减少机器的使用寿命。 Threaded connection is one of the common mechanical connections, and nuts are an essential part of most threaded connections. Due to mechanical vibration, this connection is prone to loosening, which will aggravate the vibration and generate noise and reduce the machine's performance. service life. the

发明内容 Contents of the invention

本实用新型的目的就是解决上述问题，提供一种可以防松防脱螺母。 The purpose of the utility model is to solve the above problems, and to provide a nut that can prevent loosening and detachment. the

本实用新型为实现上述目的所采用的技术方案是：一种可以防松防脱螺母，包括螺母本体、小螺栓以及橡胶垫片，其特征在于：在螺母的一对对称侧面上开设螺栓孔并加设一个配套小螺栓，两个螺栓孔只配一个小螺栓，是为了当其中一个孔被挡住时，可以使用另一个孔，另外螺栓孔的里端均嵌有一橡胶垫片，螺纹升角为1.5°，这样可以有较高的自锁性，小螺栓的螺栓头顶部设有十字槽，在没有小扳手时，可以用螺丝刀拧入，方便使用。在使用时，将螺母定位好后，再将小螺栓拧入，小螺栓底部会顶在橡胶垫片上，这样橡胶垫片就会受力变形而充填到螺母与其配套螺栓的空隙，从而增大其间的摩擦力，起到防松的目的。 The technical scheme adopted by the utility model to achieve the above purpose is: a nut that can prevent loosening and detachment, including a nut body, small bolts and rubber gaskets, is characterized in that bolt holes are set on a pair of symmetrical sides of the nut and A matching small bolt is added, and only one small bolt is used in the two bolt holes, so that when one hole is blocked, the other hole can be used. In addition, a rubber gasket is embedded in the inner end of the bolt hole, and the thread lead angle is 1.5°, which can have a higher self-locking property. There is a cross groove on the top of the bolt head of the small bolt. When there is no small wrench, it can be screwed in with a screwdriver, which is convenient to use. When in use, after positioning the nut, screw in the small bolt, the bottom of the small bolt will be on the rubber gasket, so that the rubber gasket will be deformed by force and fill the gap between the nut and its matching bolt, thereby increasing the The friction force therebetween plays the purpose of anti-loosening. the

本实用新型在目前国内外均未见报道。 The utility model all has no report both at home and abroad at present. the

具体实施方式 Detailed ways

下面结合附图和实施例对本实用新型做进一步说明。参见附图1。附图1是本实用新型加上小螺栓的俯视图。主要包括螺母本体1、橡胶垫片2、小螺栓3、螺栓孔5。 Below in conjunction with accompanying drawing and embodiment the utility model is described further. See attached drawing 1. Accompanying drawing 1 is the top view that the utility model adds small bolt. It mainly includes nut body 1, rubber gasket 2, small bolt 3, and bolt hole 5. the

螺母的使用情况如下：在使用时，将小螺栓3从螺母本体1上的其中一个孔5拧入，当拧入一定距离后，小螺栓3的底部会顶在橡胶垫片2上，这样橡胶垫片2就会受力变形而充填到螺母本体1与其相配套螺栓的空隙中，从而增大螺母本体1与其相配套螺栓间的摩擦力，起到防松的目的。另外，小螺栓3的螺栓头顶部设有十字槽4，在没有小扳手时，可以用螺丝刀拧入，方便使用。 The use of the nut is as follows: when in use, the small bolt 3 is screwed in from one of the holes 5 on the nut body 1, and when screwed in for a certain distance, the bottom of the small bolt 3 will be on the rubber gasket 2, so that the rubber The gasket 2 will be deformed by force and fill in the gap between the nut body 1 and its matching bolts, thereby increasing the friction between the nut body 1 and its matching bolts, and preventing loosening. In addition, the top of the bolt head of the small bolt 3 is provided with a cross groove 4, which can be screwed in with a screwdriver when there is no small wrench, which is convenient for use. the
