Description

Technical Field

[0001] This utility model relates to the field of nut embedding structure technology, specifically an inlaid nut embedding structure. Background Technology

[0002] Nuts are widely used in many fields such as mechanical manufacturing and electronic equipment assembly. Insert nuts, as a common type of nut, are installed on components by being embedded to connect other parts.

[0003] However, existing insert nut embedding structures have some problems, such as poor fixing effect between the nut and the component after embedding, and easy loosening or falling off when subjected to vibration or external force, affecting the stability and reliability of the connection. Therefore, those skilled in the art provide an insert nut embedding structure to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide an insert nut embedding structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An insert nut embedding structure includes a mounting base and a nut body. The mounting base has a mounting hole inside, and the inner sidewall of the mounting hole has a threaded groove. The outer surface of the nut body has an external thread, and an expansion collar is connected to the outer surface of the nut body. The inner wall of the nut body has an internal thread.

[0007] As a further improvement of this utility model: the external thread on the outer surface of the nut body is adapted to the thread groove inside the mounting hole, and the surface of the external thread is provided with raised adhesive dots.

[0008] As a further improvement of this utility model: the bottom end face of the nut body is provided with anti-slip texture, and the outer surface of the nut body is provided with anti-rust coating.

[0009] As a further improvement of this utility model: a sealing gasket is fitted on the outer surface of the nut body, and the expansion collar is made of shape memory alloy material.

[0010] As a further improvement of this utility model: the upper surface of the nut body is provided with a model mark, and the upper surface of the nut body has two hexagonal insertion holes.

[0011] As a further improvement of this utility model: two positioning grooves are formed on the upper surface of the mounting base, and two positioning protrusions are connected to the bottom surface of the nut body.

[0012] As a further improvement of this utility model: the two positioning protrusions are respectively adapted to the two positioning grooves, and the two positioning protrusions are made of elastic rubber.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This type of insert nut embedding structure achieves an initial threaded connection between the nut body and the mounting base through the interlocking of the threaded groove and the external thread. On this basis, the special material of the expansion collar, after expansion, tightly fits the inner wall of the mounting hole, further enhancing the connection strength and sealing performance between the nut and the mounting base. At the same time, it can automatically compensate for the fit clearance caused by factors such as machining errors and thermal expansion and contraction. This can effectively prevent the nut from loosening and falling off under conditions such as vibration and impact, ensuring the reliability and stability of the connection.

[0021] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, 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, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0022] 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 mechanical connection or an electrical 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.

[0023] Please see Figures 1-5 In this embodiment of the utility model, an insert nut embedding structure includes a mounting base 1 and a nut body 2. The mounting base 1 has a mounting hole 3 inside, and a threaded groove 4 is formed on the inner side wall of the mounting hole 3. The outer surface of the nut body 2 has an external thread 5, and an expansion collar 6 is connected to the outer surface of the nut body 2. The inner wall of the nut body 2 has an internal thread 7, which facilitates the threaded connection of an external screw to the nut body 2.

[0024] The external thread 5 on the outer surface of the nut body 2 is adapted to the thread groove 4 inside the mounting hole 3, and the surface of the external thread 5 is provided with raised adhesive dots. The bottom end face of the nut body 2 is provided with anti-slip texture, the outer surface of the nut body 2 is provided with an anti-rust coating, and a sealing gasket 8 is fitted on the outer surface of the nut body 2. The expansion collar 6 is made of shape memory alloy material. The raised adhesive dots on the surface of the external thread 5 can fill the thread gap when the thread is screwed on, forming a dual fixing effect of mechanical engagement and adhesive adhesion, which significantly improves the connection strength between the nut body 2 and the mounting base 1, effectively preventing the nut body 2 from loosening and falling off under vibration, impact and other working conditions, and ensuring the reliability and stability of the connection. Through the anti-slip texture on the bottom end face of the nut body 2, after the nut body 2 is installed and tightened, it can increase the friction between the nut body 2 and the connected parts, prevent the nut body 2 from rotating relative to the connected parts when under force, and further enhance the stability of the connection. The sealing gasket 8 is squeezed and deformed during the installation of the nut body 2, which can effectively fill the gap between the nut body 2 and the mounting base 1, and play a good sealing role.

[0025] The upper surface of the nut body 2 is marked with a model number 9. Two hexagonal insertion holes 10 are formed on the upper surface of the nut body 2. Two positioning grooves 11 are formed on the upper surface of the mounting base 1. Two positioning protrusions 12 are connected to the bottom surface of the nut body 2. The two positioning protrusions 12 are respectively matched with the two positioning grooves 11. Both positioning protrusions 12 are made of elastic rubber. The model number 9 allows installers to quickly identify the specifications of the nut body 2, avoiding installation errors due to the use of incorrect nut body specifications. Utilizing the design of the positioning grooves 11 and positioning protrusions 12, during the installation of the nut body 2, the positioning protrusions 12 can automatically embed into the positioning grooves 11, achieving precise positioning of the nut body 2 and preventing the nut body 2 from shifting or tilting during installation, ensuring the accuracy and consistency of the installation.

[0026] The working principle of this utility model is as follows: When using this product, first align the nut body 2 with the mounting hole 3 on the mounting base 1, insert a hexagonal wrench into the hexagonal insertion hole 10 on the upper surface of the nut body 2, and rotate the nut body 2 clockwise so that the external thread 5 on the outer surface of the nut body 2 engages with the thread groove 4 inside the mounting hole 3. During the engagement process, the raised adhesive dots on the surface of the external thread 5 fill the thread gap and enhance the connection strength. When the nut body 2 is screwed in to a certain depth, the expansion collar 6 is heated. The expansion collar 6, made of shape memory alloy, expands under heat and fits tightly against the inner wall of the mounting hole 3, further tightening the connection between the nut body 2 and the mounting base 1. At the same time, the sealing gasket 8 on the outer surface of the nut body 2 is compressed and deformed, filling the gap between the nut body 2 and the mounting base 1, thereby achieving a sealing effect. The above is the complete usage process of this product.
