[0038] It should be understood that although terms such as "first", "second", and "third" may be used herein to describe various components or signals, these components or signals should not be limited by these terms. These terms are mainly used to distinguish one component from another, or one signal from another. In addition, the term "or" used herein may include any one or a combination of more of the associated listed items depending on the actual situation.

[0039] Refer to Figures 1 to 5As shown in the figure, an embodiment of the present application discloses a sealed press riveting spacer column nut 10, including: a flange head 1 and a main body 2 arranged along the axial direction, and the outer diameter of the flange head 1 is larger than that of the main body 2;

[0040] A circular groove 22 that is recessed inward in the radial direction of the main body 2 is provided at the connection between the flange head 1 and the main body 2;

[0041] An internal threaded hole 21 is provided at one end of the main body 2 away from the flange head 1, and a receiving groove 3 for placing a seal 4 is provided inside the main body 2 at one end away from the flange head 1; this internal threaded hole 21 is a blind hole;

[0042] A seal 4, the seal 4 is made of rubber material, the seal 4 is an annular structure, and is provided with a first through hole 43, and the inner diameter of the first through hole 43 is larger than the maximum inner diameter of the internal threaded hole 21;

[0043] Wherein, a limiting part 31 capable of deforming is provided on the outer wall of the receiving groove 3. Before being connected to the seal 4, the limiting part 31 protrudes axially downward along the main body 2 and extends to the bottom of the main body 2; after the limiting part 31 is connected to the seal 4 through an installation mold, the bottom of the limiting part 31 is extruded to be flush with the bottom of the main body 2.

[0044] Specifically, in this embodiment, the seal 4 includes a first part 41 with a first outer diameter and a second part 42 with a second outer diameter, and the first outer diameter is larger than the second outer diameter. A stepped structure is formed at the connection between the outer walls of the first part 41 and the second part 42, and the bottom of the second part 42 extends out of the bottom of the limiting part 31, that is, the overall height of the seal 4 is greater than the depth of the receiving groove 3.

[0045] Specifically, in this embodiment, the limiting part 31 wraps the outer wall of the second part 42, and the inner wall of the receiving groove 3 fits with the outer wall of the first part 41, so that the seal 4 is tightly limited in the receiving groove 3.

[0046] Specifically, in this embodiment, the connection between the circular groove 22 and the main body 2 is an inclined surface, and the outer diameter of the circular groove 22 gradually increases towards the outer diameter of the main body 2, and the outer diameter of the circular groove 22 is smaller than the outer diameter of the main body 2.

[0047] Specifically, in this embodiment, the seal 4 is an O-ring.

[0048] Specifically, in this embodiment, the flange head 1 can be a polygonal structure. In another embodiment, the flange head 1 can have a toothed outer edge structure. In this application, the shape of the flange head 1 is not limited to the above structures and can be other structures capable of connecting to the plate. When the flange head is pressed into the plate, the side wall of the flange head will contact the material inside the plate. When the plate has a tendency to rotate relative to the main body, a force resisting rotation will be generated, which can make the connection of the plate more stable. The structure with a toothed outer edge can make the connection of the plate have a better anti-rotation effect, making the connection effect of the nut more reliable and having a longer service life.

[0049] With the above structure, the sealed press-fit spacer column nut 10 in this embodiment can be cold forged or machined. The seal 4 is connected to the receiving groove 3 of the main body and does not become loose. The connection is tight, the manufacturing is simple, and the cost is relatively low. At the same time, the seal does not affect the tightening torque of the overall press-fit spacer column nut.

[0050] In addition, referring to Figure 6 , this application embodiment also discloses a connection mechanism, including:

[0051] A first plate 5, the first plate 5 is provided with a preset first mounting hole;

[0052] A second plate 6, the second plate 6 is provided with a preset second mounting hole;

[0053] The sealed press-fit spacer column nut 10 as described above, the main body 2 passes through the first mounting hole, the flange head 1 is press-fitted and connected to the first plate 5, the second plate 6 is connected to the internal thread hole 21 through a bolt 7, and the first plate 5, the sealed press-fit spacer column nut 10 and the second plate 6 form an "I" - shaped structure;

[0054] Wherein, the top of the flange head is flush with the top of the first plate 5. Part of the material of the first plate 5 enters the annular groove 22 through the extrusion of the flange head 1, so that the first plate 5 is tightly connected to the main body 2. The bolt 7 passes through the second mounting hole and is connected to the internal thread hole 21 of the main body 2. The second plate 6 and the main body 2 are connected and locked by the seal 4, so that the second plate 6 is tightly connected to the main body 2.

[0055] Specifically, in this embodiment, the inner diameter of the second mounting hole is smaller than the inner diameter of the first through hole 43.

[0056] In this embodiment, the first plate 7 and the second plate 8 can be metal plates or other similar non-metal plates that can undergo plastic deformation. Additionally, the sealed press rivet spacer column nut 10 can be made of steel. Nuts made of carbon steel or alloy steel have relatively high surface strength. Nuts with relatively high surface strength can avoid failure due to situations such as the thread surface being cup-crushed during connection. With the above structure, the upper die presses the flange head 1 so that the top of the flange head is flush with the top of the first plate 5. Under the combined action of the flange head 1 and the lower die on the first plate 5, the flange head 1 is pressed into the first plate 5. Part of the material of the first plate 5 enters the annular groove 22 through the extrusion of the flange head 1, so that the first plate 5 is tightly connected to the main body 2. When connecting the second plate, only one bolt needs to be tightened for the sealed press rivet spacer column nut. The bolt 7 passes through the second mounting hole and is connected to the internal threaded hole 21 of the main body 2. The second plate 6 and the main body 2 are connected and locked by the seal 4, so that the second plate 6 is tightly connected to the main body 2. The sealed press rivet spacer column nut is connected and locked to the connection surface of the second plate through the installation die, and has the function of sealing and waterproofing. The airtightness and watertightness can reach IP69 (IP69 is a protection level standard used to describe the waterproof ability of electronic devices or device enclosures. IP stands for the abbreviation of "International Protection", and the following numbers represent the protection level; the meaning of the IP69 waterproof level standard is as follows: the first number 6: represents the protection level against solid objects, which is the highest level. The number 6 means complete protection and can prevent any size of solid objects from entering the device; the second number 9: represents the protection level against liquids, which is also the highest level. The number 9 means the protection ability of the device under high-pressure water spray and can withstand the impact of high-pressure water spray without infiltrating into this device or being damaged). The sealed press rivet spacer column nut can connect two plates at intervals and is used for relatively high-requirement connection environments.
