Abstract

The utility model discloses a kind of stop nut, including top nut and lower nut, two nuts are equipped with coaxial threaded hole, it is characterised in that the lower end surface of top nut and the upper surface of lower nut are the inclined-plane in the same direction and with taper to match;More than one block is fixedly connected on the lateral wall of top nut as a further improvement of the utility model,;The utility model has the advantages that easy to process, high production efficiency, at low cost, and convenient for grasping operating condition.

Description

Stop nut
Technical field
The utility model relates to a kind of stop nuts.
Background technique
Stop nut is used widely in recent years because of its good tightness, wherein most commonly used stop nut, It includes top nut and lower nut, one of them is equipped with conehead in addition to screw hole, another is equipped with taper hole, and conehead and taper hole are eccentric Setting;When in use, radial compression power is generated by conehead and taper hole cooperation, so that screw rod deformation is locked, avoids loosening;But For the structure because conehead, taper hole and bias increase difficulty of processing, production efficiency is low, at high cost.
Summary of the invention
The purpose of this utility model is In view of the above shortcomings of the prior art, to provide a kind of stop nut, it has Easy to process, high production efficiency, advantage at low cost.
In order to achieve the above objectives, the stop nut of the utility model, including top nut and lower nut, two nuts are equipped with coaxial Threaded hole, it is characterised in that the lower end surface of top nut and the upper surface of lower nut are match in the same direction and with the oblique of taper Face.
In use, after lower nut is installed in place, then top nut is tightened, so that the minimum point on top nut inclined-plane and lower nut are oblique After the minimum point fitting in face, again more than the minimum point on lower nut inclined-plane, top nut is generated radial squeeze by the reaction force of lower nut Pressure, so that screw rod deforms, top nut and lower nut are locked, avoid loosening;The utility model top nut and lower nut it is oblique Face is easy to process, has the advantages that high production efficiency, at low cost;
More than one block is fixedly connected on the lateral wall of top nut as a further improvement of the utility model,;Gear Block can carry out axially position to tightening tool, such as sleeve, avoid lower nut from rotating while tightening top nut, and convenient for observation The rotational angle of top nut prevented pine and the case where tension, can grasp operating condition;
The block is located at the lower half of top nut as a further improvement of the utility model,;Convenient for tightening tool control The center of gravity of top nut processed, it is easy to operate;
In conclusion the utility model has the advantages that easy to process, high production efficiency, at low cost, and convenient for grasping work Condition.
Detailed description of the invention
Fig. 1 is the usage state diagram of the utility model embodiment.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figure 1, the stop nut of the embodiment, including top nut 1 and lower nut 2, two nuts are equipped with coaxial spiral shell Pit, the lower end surface 3 of top nut 1 and the upper surface 4 of lower nut 2 are the inclined-plane in the same direction and with taper to match;In top nut 1 Lateral wall on connect firmly there are two block 5, block 5 is respectively positioned on the lower half of top nut 1.
In use, first passing through after sleeve will tighten on the installation of lower nut 2 and screw rod 6, then top nut 1 is tightened, so that upper spiral shell The minimum point on female inclined-plane 3 be bonded with the minimum point on lower nut inclined-plane 4 after, be more than again lower nut inclined-plane minimum point, lower nut 2 rises To the effect of chock, top nut 1 is generated radial compression power, so that spiral shell corresponding with top nut 1 by the reaction force of lower nut 2 6 upper deformation of bar, top nut 1 and lower nut 2 are locked, and avoid loosening, and self-locking using inclined-plane realization;Tightening top nut 1 When, block 5 can carry out axially position to sleeve, avoid lower nut 2 from rotating, and while tightening top nut 1 convenient in observation The rotational angle of nut 1 prevented pine and the case where tension, can grasp operating condition;The utility model top nut 1 and lower nut 2 inclined-plane is formed by once cutting, easy to process, has the advantages that high production efficiency, at low cost.
