The utility model provides an anti detaching Bolt Kit, which comprises a screw rod and a nut, and also comprises an anti detaching cap; an end face of the nut is provided with an annular cavity, and the screw wall between the annular cavity and the screw hole is evenly distributed with a plurality of side openings along the axial direction of the screw hole, and the side openings are communicated with the annular cavity and the screw hole; the anti detaching cap is matched with the annular cavity on the nut, and can be placed in the annular cavity, and the anti detaching cap comprises a connecting body and is connected One side of the body is fixedly provided with an elastomer. The nut and the anti detaching cap in the anti detaching bolt kit are matched. The anti detaching cap is penetrated into the ring cavity through external force, and the elastomer is extruded and deformed. The nut enters the screw hole through the side opening, filling and tightening the thread gap between the screw and the thread wall, which increases the friction between the screw teeth engaged with each other, and the elastic force of the elastomer itself can also play a role of vibration elimination and vibration elimination The utility model can effectively prevent the disappearance of friction between threads, strengthen the locking effect of threads, and solve the problem of easy loosening of bolt fasteners.

防脱螺栓套件
本技术涉及机械装备紧固件领域,特别涉及一种防脱螺栓套件。
技术介绍
机械装备从零件到整机的组装过程离不开紧固件的紧密配合。螺栓紧固件是应用最为广泛的一种紧固件形式,在装备运输以及运转作业等各个环节中,由于振动等外力的影响,螺栓紧固件会因为相互咬合的螺牙之间的压力瞬间消失而使得螺纹之间的摩擦力为零,从而使螺纹连接出现松动甚至脱落,从而影响装备的正常性能甚至会导致装备发生故障。因此,螺栓紧固件的防松防脱,一直是本领域从业人员亟需解决的技术问题。为了在市场竞争中利用技术优势抢占先机,针对上述问题,申请人组织技术人员进行了技术攻关,以期解决螺栓紧固件易松脱的问题。
技术实现思路
针对螺栓紧固件易松脱的技术问题,本技术提供了一种防脱螺栓套件,该防脱螺栓套件的技术方案是这样实现的:所述防脱螺栓套件,包括螺杆和螺母,还包括防脱帽;所述螺母一端面上开设有与螺孔同心的环形腔,环形腔与螺孔之间的螺纹壁上沿螺孔轴向均布有若干侧口,侧口连通环形腔与螺孔;所述防脱帽与螺母上的环形腔相匹配,能置于环形腔中,所述防脱帽包括连接体,连接体一侧固定设置有弹性体,防脱帽高度大于环形腔深度,连接体高度小于环形腔深度。进一步的,所述弹性体外侧壁上沿其周向设置有内凹的刻痕。进一步的,所述环形腔截面为圆环状,相应地,防脱帽为具有贯通中空腔的圆柱状结构。进一步的,所述连接体外侧壁、环形腔远离螺纹壁的内侧壁上攻有能相互匹配的螺纹。进一步的,所述连接体另一侧固定设置有基台,基台直径 ...
