Description

Technical Field

[0001] This utility model relates to the field of nut technology, and in particular to a high-strength locking nut. Background Technology

[0002] A nut is a fastener with internal threads, typically used in conjunction with a bolt or screw (parts with external threads) to detachably connect two or more parts together through the engagement of the threaded pair.

[0003] A search revealed a high-strength locking nut with publication number CN222977213U, comprising a nut shell with a threaded hole in the center, locking bolts screwed onto the front and left / right sides, and oil injection holes at the rear and left / right sides; a nylon block installed inside the locking bolts; oil reservoirs corresponding to the oil injection holes in the nut shell; and oil drain holes located below the oil reservoirs. This high-strength locking nut, through the addition of multiple sets of locking bolts, allows the nylon block to move after the nut shell is assembled with the bolts via the threaded holes. This movement causes the nylon block to press against the threads on the bolt surface, thus locking the bolt. Compared to the simple springback locking of nylon rings, this improves the locking quality of the nut.

[0004] The nut in this patent requires multiple through holes to be drilled on the side wall of the body during production to install locking bolts, nylon blocks, and for oil injection. This process is time-consuming and labor-intensive, resulting in high production costs. Furthermore, when installing the nut, it is usually necessary to use a washer, which is easily forgotten during installation, affecting the locking performance and making it less practical. Utility Model Content

[0005] In response to the technical problems in existing patents, which require multiple through holes to be drilled on the side wall of the nut body during production for installing locking bolts, nylon blocks, and oil injection, resulting in time-consuming and labor-intensive production, high production costs, and the need for washer use during installation which is easily forgotten, affecting locking performance and reducing practicality, this utility model provides a high-strength locking nut.

[0006] The technical solution adopted in this utility model is: a high-strength locking nut, comprising: Nut body; A locking assembly is mounted on the outside of the nut body and is used to prevent the nut body from loosening; The locking assembly includes an integral washer fixedly sleeved on the outer wall of one end of the nut body and a positioning pin mounted on the integral washer.

[0007] Furthermore, the integrated gasket has a positioning hole, and the positioning pin engages with the positioning hole.

[0008] Furthermore, the nut body is provided with an oil injection channel.

[0009] Furthermore, the nut body includes a base layer, a barrier layer installed on the outside of the base layer, a sealing layer installed on the outside of the barrier layer, and a functional layer installed on the outside of the sealing layer.

[0010] Furthermore, the barrier layer is specifically a zinc-nickel alloy electroplated coating, and the sealing layer is specifically a trivalent chromium passivation layer.

[0011] Furthermore, the functional layer is specifically a polytetrafluoroethylene coating.

[0012] The beneficial effects of this utility model are: The integrated gasket fits tightly against the surface of the connected parts, preventing loosening. The integrated gasket design effectively avoids assembly errors caused by human negligence. By integrating the gasket with the nut body, the number of parts is reduced, thereby improving the reliability of the overall structure. The locating pin is inserted into the locating hole to further enhance the stability of the locking assembly and prevent loosening caused by vibration.

[0013] Through a multi-layered protection mechanism consisting of a barrier layer, a sealing layer, and a functional layer, the synergistic effect of sacrificial anode, physical barrier, and chemical passivation improves the corrosion resistance of the nut body. Attached Figure Description

[0016] In the description of this utility model, it should be noted that the terms "front", "up", "down", "left", "right", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] The following is in conjunction with the appendix Figure 1-3 The present invention will be further described below.

[0019] To address the problems existing in the background art, this application proposes the following technical solution: A high-strength locking nut includes: a nut body 1 and a locking assembly 2; An oil injection channel 4 is provided on the nut body 1.

[0020] like Figure 1-3 As shown, the locking component 2 is installed on the outside of the nut body 1, and the locking component 2 is used to prevent the nut body 1 from loosening.

[0021] The locking assembly 2 includes an integral washer 201 fixedly sleeved on the outer side wall of one end of the nut body 1 and a positioning pin 202 mounted on the integral washer 201.

[0022] Furthermore, the integrated washer 201 has a positioning hole 3, and the positioning pin 202 cooperates with the positioning hole 3. The integrated washer 201 can prevent forgetting to use the washer when installing the nut body 1.

[0023] Furthermore, the nut body 1 includes a base layer 5, a barrier layer 6 installed on the outside of the base layer 5, a sealing layer 7 installed on the outside of the barrier layer 6, and a functional layer 8 installed on the outside of the sealing layer 7. The barrier layer 6 is specifically a zinc-nickel alloy electroplated coating, the sealing layer 7 is specifically a trivalent chromium passivation layer, and the functional layer 8 is specifically a polytetrafluoroethylene coating. Through the multi-layer protection mechanism composed of the barrier layer 6, the sealing layer 7, and the functional layer 8, the sacrificial anode, physical barrier, and chemical passivation work together to achieve a salt spray resistance time of over 1000 hours.

[0024] Working principle: When in use, tighten the nut body 1 onto the bolt. The integrated washer 201 fits tightly against the surface of the connected part to prevent loosening. The design of the integrated washer 201 effectively avoids assembly errors caused by human negligence. By integrating the washer with the nut body 1, the number of parts is reduced, thereby improving the reliability of the overall structure. The positioning pin 202 is inserted into the positioning hole 3 to further enhance the stability of the locking component 2 and prevent loosening due to vibration. When lubrication is required, lubricating oil can be injected through the oil injection channel 4. The lubricating oil will be evenly distributed at the threaded connection, reducing friction and extending service life. In addition, the multi-layered protective system, consisting of a zinc-nickel alloy electroplated coating, a trivalent chromium passivation layer, and a polytetrafluoroethylene coating, effectively resists the erosion of external corrosive media, ensuring that the nut can maintain excellent performance even in harsh environments.
