Technical Field

[0001] This utility model relates to the field of nuts and bolts, and more specifically, to a novel anti-loosening nut. Background Technology

[0002] A bolt is a mechanical part, a cylindrical threaded fastener that is fitted with a nut. It consists of two parts: a head and a shank (a cylinder with external threads). It needs to be used with a nut to fasten two parts with through holes. This type of connection is called a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated. Therefore, a bolted connection is a detachable connection. When existing bolts are used to fix machines or objects, the machines will vibrate during operation or the objects will vibrate in some situations. When the bolts are vibrated, they will loosen.

[0003] Therefore, a new type of anti-loosening nut is proposed to address the above problems. Utility Model Content

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1 As attached Figures 1 to 4 The novel anti-loosening nut shown includes a screw cap 1 and a mounting plate 13. The screw cap 1 has an internal threaded connection port 3 at its central axis position. Multiple rectangular limiting slots 2 are equally spaced at one end of the screw cap 1. The rectangular limiting slots 2 are arranged in a circle at one end of the screw cap 1 and are connected to the internal threaded connection port 3. A screw rod 5 is threaded through the surface of the mounting plate 13. A screw head 6 is connected to one end of the screw rod 5. The screw cap 1 is threadedly connected to the outside of the screw rod 5. A rectangular through groove 8 is opened at the center of the screw rod 5 and the screw head 6. Two locking strips 12 are inserted in the rectangular through groove 8. One end of the two locking strips 12 is connected to a connecting circular seat 10. Two rectangular connecting slots 9 are opened on the outer wall of the screw rod 5.

[0020] In use, the screw rod 5 can be threaded through the mounting plate 13 first. Then, the screw cap 1 and the screw rod 5 can be threaded together through the internal threaded connection port 3 at the central axis of the screw cap 1. The screw cap 1 is threadedly connected to the outside of the screw rod 5. Then, the two locking strips 12, which are fixedly connected to one end of the connecting circular seat 10, are inserted into the rectangular through slot 8 on the screw rod 5. Since the length of the two locking strips 12 is longer than that of the screw rod 5, the two locking strips 12 can extend out of the rectangular through slot 8 on the screw rod 5. Then, the two locking strips 12 that protrude from the screw rod 5 are bent so that the bent sections of the two locking strips 12 are engaged in the rectangular limiting slot 2 on the screw cap 1, thereby limiting the screw cap 1 and preventing the screw cap 1 from rotating and loosening and detaching from the outside of the screw rod 5.

[0021] Example 2 Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details: In a preferred embodiment, the two rectangular connecting slots 9 are connected and communicate with the rectangular through slot 8, and both the rectangular through slot 8 and the two rectangular connecting slots 9 are adapted to the two locking strips 12. The length of the two locking strips 12 is longer than the length of the screw rod 5. The two locking strips 12 are made of a flexible alloy metal material. In use, because the length of the two locking strips 12 is longer than that of the screw rod 5, after inserting the two locking strips 12 into the rectangular through slot 8 opened at the central axis position of the screw rod 5, the two locking strips 12 can extend beyond the opening on the screw rod 5. The rectangular through groove 8 is followed by two locking bars 12 protruding from the screw rod 5. The rectangular limiting groove 2 is adapted to the locking bars 12, so that the bent sections of the two locking bars 12 are precisely engaged in the rectangular limiting groove 2 opened on the screw cap 1, preventing the screw cap 1 from rotating. The end of the screw head 6 away from the screw rod 5 is provided with a circular clearance groove 7. The circular clearance groove 7 is connected to one end of the rectangular through groove 8. At the same time, the connecting circular seat 10 of one end of the two locking bars 12 can be engaged in the circular clearance groove 7.

[0022] In a preferred embodiment, a plurality of elastic compression plates 4 are fixedly arranged at equal intervals at one end of the screw cap 1 away from the rectangular limiting slot 2, and the plurality of elastic compression plates 4 are arranged in a circular distribution at one end of the screw cap 1. When the screw cap 1 is screwed and connected to the outside of the screw rod 5, the plurality of elastic compression plates 4 at one end of the screw cap 1 will squeeze the mounting plate 13. After the screw cap 1 is installed, the squeezed elastic compression plates 4 will act on the screw cap 1 in turn, increasing the friction between the screw cap 1 and the mounting plate 13, thereby further improving the stability of the connection of the screw cap 1 and preventing the screw cap 1 from loosening.

[0023] In a preferred embodiment, a connecting ring 11 is fixedly provided on the outer side of the connecting circular seat 10. The outer side of the connecting ring 11 is provided with rough texture to increase the friction between the hand and the connecting ring 11. In use, the connecting circular seat 10 can be pulled by the connecting ring 11 to pull the connecting circular seat 10 and the locking strip 12 out of the rectangular through groove 8 or to insert the two locking strips 12 into the rectangular through groove 8.

[0024] The working process of this utility model is as follows: First, the screw rod 5 can be threaded through the mounting plate 13. Then, the screw cap 1 and the screw rod 5 can be threadedly connected through the internal thread connection port 3 opened at the central axis position of the screw cap 1, so that the screw cap 1 is threadedly connected to the outside of the screw rod 5. Then, the two locking strips 12 fixedly connected to one end of the connecting circular seat 10 are inserted into the rectangular through groove 8 opened on the screw rod 5 through the connecting ring 11. Since the length of the two locking strips 12 is longer than that of the screw rod 5, the two locking strips 12 can extend out of the rectangular through slot 8 opened on the screw rod 5. Then, the two locking strips 12 protruding from the screw rod 5 are bent so that the bent sections of the two locking strips 12 are engaged in the rectangular limiting slot 2 opened on the screw cap 1, thereby limiting the screw cap 1 and preventing the screw cap 1 from rotating and loosening from the outside of the screw rod 5. Finally, the bent locking strips 12 protruding from the screw cap 1 can be cut off with a cutting tool to maintain the appearance and prevent the two locking strips 12 from being subjected to external force again, releasing the limiting of the screw cap 1 and causing the screw cap 1 to loosen easily. The above is the working principle of this new type of anti-loosening nut.
