Description

Technical Field

[0001] The utility model belongs to the technical field of nuts, in particular to a locking nut for automobile engines. Background Art

[0002] The locking nuts currently used for automobile engine compartment inserts tend to constantly vibrate when the engine is running, making the locking nuts of the engine compartment inserts more likely to loosen, affecting the driving safety of the car when the car is running. The locking nuts currently used for automobile engine compartment inserts tend to constantly vibrate when the engine is running, making the locking nuts of the engine compartment inserts more likely to loosen, affecting the driving safety of the car when the car is running.

[0003] Most existing locking nuts rely on the characteristics of the material itself to perform locking work during use. After long-term use, the material stress changes, resulting in a decrease in locking efficiency, and then the nut becomes loose and needs to be replaced. This is not only troublesome but also wasteful. To this end, we propose a locking nut for automobile engines. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The auxiliary device is provided to improve the locking performance of the nut body and reduce the possibility of loosening and spinning caused by vibrations generated during the use of the engine. The auxiliary device can be removed and replaced, so that when the device is used for a long time, the locking performance of the nut can be improved without replacing the nut body;

[0013] 2. The stability of the device is improved by setting a metal sheet, and the possibility of the nut body rotating on its own after installation is reduced. The auxiliary device is assisted by setting a second screw to help the auxiliary device improve the stability of the nut body and improve the efficiency of the device.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-4A locking nut for an automobile engine includes a nut body 100. Multiple sets of auxiliary devices 110 are evenly arranged on the outside of the nut body 100. The multiple sets of auxiliary devices 110 are arranged in a circular array. The left auxiliary device 110 includes a first screw 111. A spring 112 is fixedly connected to the right side of the first screw 111. A cone block 113 is fixedly connected to the right side of the spring 112. The nut body 100 is provided with a groove matching the auxiliary device 110. During the use of the device, the first screw 111 is rotated, and the spring 112 and the cone block 113 are driven to move to the right by the first screw 111, and then the screw 111 is rotated. The cone block 113 contacts other workpieces, thereby increasing the friction between the device and other workpieces, reducing the risk of the nut loosening, and improving the stability of the device. By setting the auxiliary device 110, the locking performance of the nut body 100 is improved, and the possibility of loosening and rotating due to vibrations generated during the use of the engine is reduced. The outer side of the nut body 100 is fixedly connected with multiple groups of second screws 130. By setting the second screws 130 to assist the auxiliary device 110, the auxiliary device 110 is helped to improve the stability of the nut body 100 and improve the efficiency of the device.

[0023] The left side of the cone block 113 is fixedly connected with a guide rod 114, and the right side of the first screw 111 is provided with a socket matching the guide rod 114. The guide rod 114 is in the shape of a rectangular parallelepiped. The stability of the cone block 113 is improved by setting the guide rod 114, and the risk of the cone block 113 being unable to effectively engage with other workpieces due to tilting problems is avoided. The left side of the guide rod 114 is fixedly connected with a limit plate 115, and the first screw 111 is provided with a groove matching the guide rod 114. The limit plate 115 is provided to limit the movable stroke of the guide rod 114, thereby improving the stability of the device.

[0024] Multiple groups of metal sheets 120 are evenly fixedly connected to the lower side of the nut body 100. The metal sheets 120 are arranged at an angle, and the inclination direction of the metal sheets 120 is opposite to the spiral direction of the internal thread of the nut. By setting the metal sheets 120, the stability of the use of the device is improved, and the possibility of the nut body 100 rotating on its own after installation is reduced.
