Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of nuts, in particular to a novel anti-loosening nut. Background Art
[0002] Nuts commonly used in the market generally include a nut body, a cavity formed in the nut body, and an internal thread formed on the inner wall of the nut body. When in use, the nut only needs to be tightened onto the bolt.
[0003] However, when nuts are used in objects or mechanical structures that are frequently moved and vibrated, they can easily become loose and fall off the bolts after long-term use, which can cause unpredictable consequences. Although some existing anti-loosening nuts can achieve locking between bolts and nuts, they are often complex in structure, and their locking components cannot be locked automatically. After the nut and the bolt are tightened, an additional process must be performed to apply a certain force to the locking component on the loose nut to deform the locking component, thereby locking the nut and the bolt. For this reason, we propose a new anti-loosening nut. Utility Model Content
[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a new anti-loosening nut, which effectively solves the above problem.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new anti-loosening nut, comprising a nut body, three groups of springs are connected to the lower side of the nut body, the lower sides of the three groups of springs are connected to an anti-slip plate, and the lower side of the anti-slip plate is provided with an anti-slip groove.
[0006] Preferably, three groups of insertion rods are connected to the upper side of the anti-slip plate, and the body of the nut body is provided with insertion holes matching the insertion rods.
[0007] Preferably, a groove is provided on the lower side of the nut body, and the spring is located inside the groove of the nut body.
[0008] Preferably, upper and lower sides of the insertion rod are connected to limit plates, and the limit plates are respectively located on the upper and lower sides of the nut body.
[0009] Preferably, placement grooves matching the limiting plates are provided on both the upper and lower sides of the nut body.
[0010] Preferably, an action groove is provided on the upper side of the nut body, and a rubber sleeve is placed in the action groove of the nut body.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. The nut body can be prevented from loosening by arranging a spring and cooperating with the anti-slip plate. The spring will squeeze the anti-slip plate so that the anti-slip plate is always on the surface of the machine. The anti-slip plate will rotate with the assistance of the anti-slip pattern on the lower side of the anti-slip plate, so that the anti-slip plate will not rotate much, thereby improving the anti-loosening performance of the device;
[0013] 2. By setting the insertion rod to limit the anti-slip plate, the risk of damage caused by the anti-slip plate being cut obliquely is prevented. By setting the limiting plate to limit the insertion rod, the insertion rod is prevented from being separated from the nut body. At the same time, the lifting and lowering position of the anti-slip plate can also be limited to improve the stability of the use of this device. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0022] See also Figure 1-4A novel anti-loosening nut includes a nut body 100, three sets of springs 110 are fixedly connected to the lower side of the nut body 100, an anti-slip plate 120 is connected to the lower side of the three sets of springs 110, and an anti-slip groove is arranged on the lower side of the anti-slip plate 120. The device can play the anti-loosening performance of the nut body 100 by arranging the springs 110 and the anti-slip plate 120. The springs 110 will squeeze the anti-slip plate 120, so that the anti-slip plate 120 is always on the surface of the machine, so that the anti-slip plate 120 rotates and is hit by the anti-slip groove on the lower side of the anti-slip plate 120. The auxiliary device thus prevents itself from rotating greatly, thereby improving the anti-loosening performance of the device. Three sets of plug rods 130 are fixedly connected to the upper side of the anti-slip plate 120. The body of the nut body 100 is provided with a plug hole matching the plug rod 130. The anti-slip plate 120 is limited by setting the plug rod 130 to prevent the anti-slip plate 120 from being cut obliquely and causing the risk of damage. A groove is provided on the lower side of the nut body 100. The spring 110 is located inside the groove of the nut body 100. The groove is provided so that the spring 110 has a telescopic space, thereby preventing the spring 110 from being damaged. 10 is squeezed and damaged by the anti-slide plate 120, and the upper and lower sides of the insertion rod 130 are fixedly connected to the limit plates 140, which are respectively located on the upper and lower sides of the nut body 100. The insertion rod 130 is limited by setting the limit plates 140 to prevent the insertion rod 130 from separating from the nut body 100. At the same time, the lifting and lowering position of the anti-slide plate 120 can also be limited to improve the stability of the device. The upper and lower sides of the nut body 100 are provided with placement grooves matching the limit plates 140. By setting the placement grooves, the limit plates 140 will not The position of the anti-skid plate 120 is affected, so that the anti-skid plate 120 can contact the nut body 100 after installation, so that the staff can apply force to the nut body 100 without considering the risk of damaging the insert rod 130 or the limit plate 140. An action groove is opened on the upper side of the nut body 100, and a rubber sleeve 150 is placed in the action groove of the nut body 100. By setting the rubber sleeve 150, the device can contact the screw in the nut body 100 after installation, thereby reducing the anti-loosening performance during the subsequent use of the device.
[0023] Working principle: When the novel solution is implemented, after the device is connected to the screw rod when in use, when the machine vibrates during use, the anti-skid plate 120 is squeezed, and the anti-skid plate 120 squeezes the nut body 100. The nut body 100 rotates after being squeezed. However, since the anti-skid plate 120 has anti-skid grooves on the lower side, the nut body 100 and the anti-skid plate 120 will fit the machine tightly when installed. Due to the metal material, the contact position between the anti-skid plate 120 and the machine will be slightly deformed due to the anti-skid grooves, so that the nut body 100 drives the anti-skid plate 120 to rotate in the opposite direction. When the nut body 100 is rotated, it will generate friction with the surface of the machine, thereby reducing the possibility of the nut body 100 rotating in the opposite direction and loosening. If the nut body 100 and the anti-skid plate 120 are slightly loosened, if the machine vibrates and squeezes the anti-skid plate 120 again, the anti-skid plate 120 drives the insertion rod 130 to swing up and down in the insertion hole of the nut body 100, and the spring 110 will squeeze the anti-skid plate 120, so that the anti-skid plate 120 is always on the surface of the machine, and the rotation of the anti-skid plate 120 will be assisted by the anti-slip grooves on the lower side of the anti-skid plate 120, so that it will not produce a large rotation, thereby improving the anti-loosening performance of the device.
