Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of nylon nuts, in particular to a nylon anti-loosening nut. Background Art
[0002] Generally, when bolts and nuts are subjected to external shock and vibration, their binding force is easy to weaken, and they will be easily loosened, and even the bolts and nuts will be completely separated, burying safety hazards such as damage and collapse of the structure. Loosening of fastening due to frequent vibration has become a common problem. Nylon nuts can have excellent insulation properties, are non-magnetic, heat-insulating, and light in weight. Nylon nuts made of certain materials can be used with both plastic screws and metal screws, and are widely used in various industrial fields. The nylon self-locking nuts on the existing market usually include a nut body, an internal threaded hole is provided in the center of the nut body, a thin-walled sleeve structure is provided at the upper end of the nut body, the internal threaded hole passes through the nut body, and a nylon gasket is provided on the inner wall of the thin-walled sleeve. However, when the nylon nut is tightened, the nylon gasket in the thin-walled sleeve is not easy to be pressed, and its own surface is smooth, so it is easy to spin, which makes the nut very unstable when locking the bolt.
[0003] A Chinese utility model patent with publication number CN212744652U discloses a nylon nut, which is manufactured by aligning four positioning holes on the lower side of a nylon pad with the upper ends of four positioning rods and inserting the nylon pad, and making the positioning holes squeeze the surface of a conical rubber block so that the conical rubber block is squeezed into a slot, thereby fixing the nylon pad in the mounting slot and preventing it from rotating, making the nylon pad more secure when locking the bolt. However, the device still has some other problems. For example, the device improves the stability of the nut when locking the bolt by strengthening the stability between the fixed nylon pad and the nut. However, this only increases the friction between the bolt and the nut, and the stability of the connection is not that stable. Utility Model Content

[0026] Embodiment 1:
[0027] like Figure 1-Figure 2 As shown, this embodiment provides a nylon anti-loosening nut, including:
[0028] A nylon nut 100 is provided with a groove 110, and an internal thread 120 is provided inside the groove 110;
[0029] The nylon screw 200 is disposed inside the groove 110, and an external thread 220 is disposed on the periphery of the nylon screw 200;
[0030] The fastener 300 is disposed inside the groove 110;
[0031] The nylon screw 200 is provided with an opening 210 for use with the fastener 300 .
[0032] In the present technical solution, in order to increase the fastening force between the nylon nut 100 and the nylon screw 200, a groove 110 is provided on one side of the nylon nut 100, an internal thread 120 is provided on the inner wall of the groove 110, and an external thread 220 is provided on the outer side of the nylon screw 200. The nylon screw 200 is meshed with the internal thread 120 of the nylon nut 100 through the external thread 220. At the same time, in order to increase the bonding force, an opening 210 is provided on the outer side of one end of the nylon screw 200 close to the groove 110, and a fastener 300 is provided on the inner wall of the nylon nut 100. By using the fastener 300 in conjunction with the opening 210, loosening between the nylon nut 100 and the nylon screw 200 can be prevented.
[0033] Embodiment 2:
[0034] This embodiment provides a nylon anti-loosening nut, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0035] like Figure 2 As shown, in this embodiment, a mounting hole 130 is further defined on the inner wall of the groove 110 , and the fastener 300 is disposed inside the mounting hole 130 .
[0036] In the present technical solution, in order to facilitate the installation of the fastener 300, a mounting hole 130 is opened on the inner wall of the groove 110, and the internal threads 120 are retained on the upper, lower, left and right sides of the mounting hole 130, ensuring that the external thread 220 of the threaded rod can continue to engage with the internal thread 120 at the position of the mounting hole 130, and when the opening 210 of the nylon screw 200 has not reached the position of the mounting hole 130, the fastener 300 can be installed inside the mounting hole 130, so that the nylon bolt can contact the top of the groove 110 of the nylon nut 100.
[0037] Embodiment 3:
[0038] This embodiment provides a nylon anti-loosening nut, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0039] like Figure 2 As shown, in this embodiment, the fastener 300 further includes:
[0040] The spring 310 is disposed in the mounting hole 130, and one end of the spring 310 is fixedly connected to the bottom surface of the mounting hole 130;
[0041] The connecting plate 320 is fixedly disposed on the other end of the spring 310;
[0042] The fixed ball 330 is fixedly disposed on a side of the connecting plate 320 away from the spring 310 .
[0043] In the present technical solution, in order to enable the fastener 300 to be used in conjunction with the nylon screw 200, a transverse spring 310 is provided at the bottom end of the mounting hole 130, one end of the spring 310 is fixed to the bottom end of the mounting hole 130, the other end of the spring 310 is fixedly connected to one side of the connecting plate 320, and the other side of the connecting plate 320 is fixedly connected to a fixed ball 330. When the nylon screw 200 has not reached the position of the fastener 300, the fixed ball 330 will be prevented from being loosened by the spring 310. The spring 310 bounces into the inside of the groove 110 of the nylon nut 100. When the nylon screw 200 reaches the position of the fastener 300, the nylon screw 200 of the knob will squeeze the fixed ball 330, squeezing the fixed ball 330 into the inside of the mounting hole 130. When the opening 210 of the nylon screw 200 is just opposite to the mounting hole 130, the spring 310 will push the fixed ball 330 into the inside of the opening 210, thereby increasing the fastening force between the nylon screw 200 and the nylon nut 100.
[0044] Embodiment 4:
[0045] This embodiment provides a nylon anti-loosening nut, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0046] like Figure 1-Figure 2 As shown, in this embodiment, a fixing frame 230 made of magnetic blocks is fixed on the inner wall of the opening 210 .
[0047] In the present technical solution, in order to prevent the fixed sphere 330 from being pushed away by the rotation of the nylon screw 200 when entering the opening 210, a fixed frame 230 made of a magnetic block is arranged on the inner wall of the opening 210, which can generate a magnetic force on the fixed sphere 330 and firmly fix the fixed sphere 330 inside the installation frame. When the fixed sphere 330 is completely brought into the interior of the fixed frame 230 by the suction force generated by the magnetic block, it can enter the interior of the installation frame with the fixed plate. In this way, when the nylon screw 200 continues to rotate, the spring 310 can be deformed along the direction of rotation of the nylon screw 200 and stuck in the position where the external thread 220 and the internal thread 120 are meshed, thereby increasing the friction between the nylon screw 200 and the nylon bolt.
[0048] Embodiment 5:
[0049] This embodiment provides a nylon anti-loosening nut, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0050] like Figure 1-Figure 2 As shown, in this embodiment, the length, width and depth of the fixing frame 230 are the same as the diameter of the fixing sphere 330 plus the length, width and height of the connecting plate 320.
[0051] In the present technical solution, in order to facilitate the coordinated use of the fixed sphere 330 and the mounting frame, the size of the fixed frame 230 is set so that the fixed sphere 330 and the connecting plate 320 can be completely placed inside the fixed frame 230, so that the fixed sphere 330 and the connecting plate 320 can be completely fixed inside the fixed frame 230.
[0052] Embodiment 6:
[0053] This embodiment provides a nylon anti-loosening nut, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0054] like Figure 2 As shown, in this embodiment, the fixing sphere 330 is made of metal material, and the surface of the fixing sphere 330 is smooth.
[0055] In the present technical solution, in order to enable the fixed sphere 330 to generate magnetic force with the fixed frame 230, the fixed sphere 330 and the connecting plate 320 are both made of metal materials, so that the connecting plate 320 and the fixed sphere 330 can be installed inside the fixed frame 230, and the surface of the fixed sphere 330 is set to a smooth surface, which can be easily compressed into the interior of the mounting hole 130 when the opening 210 of the nylon screw 200 has not reached the fastener 300.
[0056] Embodiment 7:
[0057] This embodiment provides a nylon anti-loosening nut, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0058] like Figure 1-Figure 2 As shown, in this embodiment, when the spring 310 is in a fully relaxed state, the length of the spring 310 , the connecting plate 320 and the fixing sphere 330 is just enough to allow the fixing sphere 330 to completely enter the fixing frame 230 .
[0059] In the present technical solution, in order to ensure that the fixing ball 330 and the connecting plate 320 of the fastener 300 can completely enter the interior of the fixing frame 230 when the opening 210 of the nylon screw 200 reaches the position of the fastener 300, the spring 310 is relaxed so that the position of the fixing plate just reaches the position of the mounting opening of the mounting hole 130, and the position of the fixing ball 330 is inside the groove 110, so that when the opening 210 is facing the mounting hole 130, the spring 310 is subjected to the pulling force generated by the magnetic fixing frame 230 on the connecting plate 320 and the fixing ball 330, and the fixing ball 330 and the connecting plate 320 are fixed inside the fixing frame 230 by magnetic force, so that the fastener 300 will not affect the normal cooperation between the nylon screw 200 and the nylon nut 100, and can also prevent the nylon nut 100 and the nylon bolt from loosening.
[0060] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
