Description

Technical Field

[0001] This utility model relates to the field of nut structure technology, and more specifically, to a high-strength anti-loosening nut. Background Technology

[0002] A nut is a common fastener, typically used in conjunction with a bolt or screw to achieve a mechanical connection through threaded engagement. It is widely used in machinery, building structures, automotive manufacturing, and electronic equipment.

[0003] Currently, when nuts are used in automobiles or some large mechanical equipment, these machines or equipment will generate significant vibrations during operation. If the nuts are used for a long time, they may loosen and fall off, thereby affecting the safety of the machine or equipment.

[0004] Therefore, in view of this, the existing structure was studied and improved to provide a high-strength anti-loosening nut, in order to achieve a more practical purpose. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a high-strength anti-loosening nut that can freely open and close the anti-loosening function, preventing the nut body from loosening and falling off due to large vibrations, thus ensuring the safety of the machinery or equipment using the nut and improving the nut's practicality.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A high-strength anti-loosening nut includes a nut body with a cavity structure inside. One end of the cavity structure is connected to the inner ring of the nut body, and the other end of the cavity structure is connected to the outer ring of the nut body. A slide rail is fixed inside the cavity structure.

[0010] The cavity structure is equipped with an anti-detachment component, which includes:

[0011] A sliding frame slides along a slide rail. One end of the sliding frame is movably connected to a threaded straight rod via a bearing. One end of the threaded straight rod extends to the outside of the nut body and is fixedly fitted with a knob. A connecting strip is hinged to the bottom of the sliding frame. The end of the connecting strip is fixed with a tooth. A spring is fixedly installed between the middle of the connecting strip and the center of the top of the inner part of the sliding frame.

[0012] Furthermore, the cavity structure is a T-shaped structure, with one end of the T-shaped structure connected to the inner side of the nut body and communicating with the inner ring of the nut body, and the tooth head located at the end position of the T-shaped structure.

[0013] Furthermore, the spring is always in a compressed state.

[0014] Furthermore, when the tooth rotates, the angle between it and the horizontal direction ranges from 0 to 10°.

[0015] Furthermore, the tooth tip has an obtuse-angled oblique triangular structure, and the tip of the tooth tip faces upward.

[0016] Furthermore, one end of the cavity structure is connected to a threaded hole, which extends from the cavity structure to the outside of the nut body, and the threaded straight rod is threadedly connected to the threaded hole through the threaded portion.

[0017] Furthermore, six winglets are fixedly installed on the side of the knob, and the six winglets are distributed radially at equal angles.

[0018] 3. Beneficial effects

[0019] Compared with existing technologies, the advantages of this utility model are:

[0020] In this solution, when the nut body is in use, the position of the sliding frame, connecting bar, and toothed head can be adjusted by the knob and threaded straight rod in the anti-loosening component. When the toothed head slides out of the cavity structure, it can achieve the anti-loosening effect of the nut body. At this time, when this type of nut body is applied to automobiles or some large mechanical equipment, even if the machinery or equipment will generate a large amplitude of vibration during operation, the nut body will not loosen or fall off, thus ensuring the safety of the machinery or equipment.

[0021] When the toothed head is fully retracted into the cavity structure by controlling the knob and threaded straight rod in the anti-loosening component, the nut body can be easily loosened;

[0022] In summary, this type of nut allows for the free activation and deactivation of its anti-loosening function, preventing the nut from loosening or falling off due to significant vibration. This ensures the safety of the machinery or equipment using the nut and improves its practicality. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0032] Example:

[0033] Please see Figure 1 - Figure 5 A high-strength anti-loosening nut includes a nut body 1, a cavity structure 101 is provided inside the nut body 1, one end of the cavity structure 101 is connected to the inner ring of the nut body 1, the other end of the cavity structure 101 is connected to the outer ring of the nut body 1, and a slide rail 102 is fixed inside the cavity structure 101.

[0034] The cavity structure 101 is equipped with an anti-detachment component 2, which includes:

[0035] The sliding frame 201 slides along the slide rail 102. One end of the sliding frame 201 is movably connected to a threaded straight rod 202 via a bearing. One end of the threaded straight rod 202 extends to the outside of the nut body 1 and is fixedly installed with a knob 203. A connecting strip 204 is hinged to the bottom of the inner side of the sliding frame 201. A tooth 205 is fixed to the end of the connecting strip 204. A spring 206 is fixedly installed between the middle of the connecting strip 204 and the center of the inner top of the sliding frame 201.

[0036] See Figure 2 , Figure 3 , Figure 4 , Figure 5Specifically, the cavity structure 101 is a T-shaped structure. One end of the T-shaped structure is connected to the inner side of the nut body 1 and communicates with the inner ring of the nut body 1. The tooth 205 is located at the end of the T-shaped structure.

[0037] Specifically, spring 206 is always in a compressed state.

[0038] Specifically, when the tooth 205 rotates, the angle between it and the horizontal direction ranges from 0 to 10°.

[0039] Specifically, tooth 205 has an obtuse-angled oblique triangular structure, and the tip of tooth 205 faces upward.

[0040] When the nut body 1 is tightened clockwise, the tooth 205 bounces up and then falls under the action of the spring 206. The process of bouncing up and falling is repeated during the tightening of the nut body 1.

[0041] When the nut body 1 vibrates, the sliding frame 201 restricts the rotation angle of the connecting bar 204 and the tooth 205, thus preventing the nut body 1 from rotating counterclockwise and thus preventing the nut body 1 from being loosened, thereby achieving the function of preventing the nut body 1 from falling off.

[0042] See Figure 2 , Figure 3 , Figure 4 , Figure 5 Specifically, one end of the cavity structure 101 is connected to a threaded hole 1011, which extends from the cavity structure 101 to the outside of the nut body 1. The threaded straight rod 202 is threadedly connected to the threaded hole 1011 through the threaded portion.

[0043] Specifically, six blades 2031 are fixedly installed on the side of the knob 203, and the six blades 2031 are distributed radially at equal angles.

[0044] The wing 2031 allows the knob 203 to be rotated easily. When the knob 203 is rotated clockwise, the threaded straight rod 202 is screwed in along the direction of the threaded hole 1011. At this time, the tooth 205 extends to the outside of the cavity structure 101, which can play a role in preventing the nut body 1 from falling off when in use.

[0045] When the knob 203 is turned counterclockwise, the threaded rod 202 is screwed out along the direction of the threaded hole 1011. At this time, the tooth 205 is completely retracted into the cavity structure 101, which can release the anti-loosening effect of the nut body 1.

[0046] Working principle:

[0047] The nut body 1 can freely open and close the anti-loosening function.

[0048] When the anti-drop function is activated, when the knob 203 is turned clockwise, the threaded straight rod 202 is screwed into the threaded hole 1011. At this time, the toothed head 205 extends to the outside of the cavity structure 101. When the nut body 1 is tightened clockwise, the toothed head 205 bounces up and then falls under the action of the spring 206. During the tightening process of the nut body 1, the process of bouncing up and falling down is repeated. When the nut body 1 vibrates, the sliding frame 201 restricts the rotation angle of the connecting bar 204 and the toothed head 205, thus preventing the nut body 1 from rotating counterclockwise and thus preventing the nut body 1 from being loosened, thereby realizing the anti-drop function of the nut body 1.

[0049] When the anti-loosening function is deactivated, when the knob 203 is turned counterclockwise, the threaded rod 202 is screwed out along the direction of the threaded hole 1011. At this time, the toothed head 205 is completely retracted into the cavity structure 101, which can deactivate the anti-loosening effect of the nut body 1. At this time, the nut body 1 functions the same as a common nut.

[0050] In this way, the nut body 1 can be used.

[0051] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
