Problems solved by technology

There is also a method of placing small steel balls in the holes of the base to increase friction, but in this method, the connection between the base and the nut is essentially achieved by friction, so under a large pulling force, it is easy to make the bolt The whole is pulled out from the base or its position changes, seriously affecting the accuracy of measurement

Embodiment 1

[0040] Such as figure 1 , figure 2 As shown, a lock nut includes a nut body 1, and the inner surface of the nut body 1 is provided with threads, and is characterized in that:

[0041] The nut body 1 is a circular cylindrical structure, and the nut body 1 is provided with two holes, and the line connecting the centroids of the holes passes through the central axis of the nut body 1 and is perpendicular to the central axis of the nut body 1 . A pin one 3 is provided in the hole on the right side, and a pin two 4 is provided in the hole on the left side. The lengths of pin one 3 and pin two 4 are greater than the thickness of the nut body 1 . A spring 5 is connected between the pin one 3 and the pin two 4 . Pin one 3, pin two 4, and spring 5 have a horizontal total length greater than the outer diameter of the nut body 1. When there is no external pressure, under the elastic force of the spring 5, part of the structure of pin one 3 and pin two 4 can protrude out of the hole....

Embodiment 2

[0047] The only difference between this implementation and Example 1 is that, as image 3 As shown, the outer surface of the pin of the lock nut is an arc surface protruding in the middle.

Embodiment 3

[0049] The only difference between this implementation and Example 1 is that, as Figure 4 As shown, the outer surface of the pin of the lock nut is an arc surface that becomes narrower as it gets closer to the bottom end of the nut body 1 .

Abstract

The invention discloses a lock nut, a lock structure using the lock nut and a method for mounting the lock structure. The lock nut comprises a nut body with the inside provided with threads. The nut body is in a cylinder structure, two holes are formed in the nut body, a connection line of centroids of the holes penetrates and perpendicular to a central axis of the nut body, and a movable pin is arranged in each of the holes. A lock device comprises a base, a part to be fastened, the lock nut and a bolt, wherein the lock nut is mounted in a hole of the base, and two grooves matched with the pins are arranged in the hole of the base at a depth corresponding to the depths of the pins. When the lock nut is inserted in the hole, the pins are pushed to press the outer end of the nut into the grooves, and the lock nut and the base are connected into a whole by the pins, so that the lock nut cannot loose or fail easily. By means of the lock device, the problem that the nut might be pulled out due to too large external force when equipment is mounted on large-size stone bases can be effectively solved.

Description

technical field [0001] The present invention relates to a locking device used for fixing various devices on marble, granite or other large-size bases, in particular to a locking nut, a locking structure using the locking nut and an installation method thereof. Background technique [0002] Nuts, also called nuts, are parts that are screwed together with bolts or screws for fastening. There are many kinds of nuts. According to different materials, nuts are divided into several types such as carbon steel nuts, high-strength steel nuts, stainless steel nuts, and plastic steel nuts. Bolts are cylindrical threaded fasteners that mate with nuts. Usually, since the nuts and bolts are made of high-strength materials, the threaded connection between them is generally more reliable. Through the cooperation of bolts and nuts, the parts to be fastened can be fastened. In the past, it was known that the equipment installed on a large-sized base cannot penetrate the base due to the sho...
