Technical Field
[0001] This utility model discloses an adjustable sealing press-fit stud, which relates to the field of press-fit stud technology. Background Technology
[0002] Press-fit studs (also known as press-fit nuts or press-fit bolts) are fasteners commonly used for threaded connections on sheet metal, plastic, or composite materials. They are components that secure a stud or nut to the surface of a workpiece using a press-fit process, allowing for easy installation of bolts or screws in subsequent operations. Press-fit studs are widely used in automotive manufacturing, electronics, home appliances, aerospace, and other industrial sectors, and are particularly suitable for applications requiring threaded connections on thin sheets and plastic parts.
[0003] Press-fit studs typically consist of a stud body, a threaded portion, and a riveting portion. Their working principle involves pressing the riveting portion of the stud into the hole of the workpiece using specific pressure, and then securing the stud firmly through the deformation force after riveting. In certain specific scenarios, press-fit studs are required to achieve a sealing effect, and their applications are wide-ranging. Traditional press-fit studs may not be able to achieve adjustable clamping force to control the sealing effect in such situations. Therefore, an adjustable sealing press-fit stud is needed to solve these problems. Utility Model Content
[0004] The purpose of this invention is to provide an adjustable sealing press-fit stud, so that the press-fit stud can achieve an adjustable sealing connection.

Four sets of tube plates are disposed, evenly distributed along the arc contour of the stud body. A sealing ring is disposed on each tube plate to achieve a sealing effect during connection. An internal thread is disposed on the inner side of the tube plate, and an external thread is disposed on the outer side of the tube plate. The adjustable ring is threadedly connected to the tube plate. The adjustable ring moves up and down along the external thread on the tube plate within the stud body.
[0006] Preferably, the inner diameter of the adjustable ring is provided with an internal thread.
[0007] Preferably, a limiting stage is provided on the stud body.
[0008] Preferably, the segments are provided with a certain degree of inclination.
[0009] Preferably, there is a gap for movement between the four groups of segments.
[0010] Preferably, a sealing groove is provided at the upper end of the tube segment, and a sealing ring is installed in the sealing groove.
[0011] Preferably, the adjustable ring is equipped with an anti-slip rubber ring to facilitate tightening by the operator.
[0012] Compared with the prior art, the beneficial effects of this utility model are: by setting a sealing ring on the tube segment, the sealing strength and sealing performance of other parts are increased in the subsequent connection steps. The adjustable ring connected by the external thread can move up and down with the external thread on the outside of the tube segment to adjust the inner diameter of the circular tube formed by the four tube segments, so as to achieve adjustable connection and adjustable connection tightness. At the same time, it can also achieve the function of reinforcing the connection, thereby achieving the effect of adjustable sealing connection of the press-fit stud. Attached Figure Description

[0016] 1. Stud body; 11. Limiting platform; 2. Adjustable ring; 21. Anti-slip rubber ring; 22. Internal thread of the ring; 3. Tube segment; 31. Internal thread; 32. External thread; 5. Sealing ring; 6. Movement clearance. Detailed Implementation
[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Specific implementation examples:
[0019] like Figure 1 As shown, an adjustable sealing press-fit stud includes a stud body 1, an adjustable ring 2 mounted on the stud body 1, and a tube 3 disposed on the stud body 1. The tube 3 is provided in four sets, and the four sets of tube 3 are evenly distributed along the arc contour of the stud body 1. A sealing ring 5 is provided on the tube 3 to achieve a sealing effect during connection. An internal thread 31 is provided on the inner side of the tube 3, and an external thread 32 is provided on the outer side of the tube 3. The adjustable ring 2 is threadedly connected to the tube 3.
[0020] The adjustable ring 2 moves up and down along the external thread 32 on the tube sheet 3 on the stud body 1.
[0021] During the installation of press-fit nuts, pressure is applied using a press-fit device to engage the nut's riveted portion with the workpiece, thereby fixing the nut to the workpiece surface. The specific working principle is existing technology and will not be elaborated upon here.
[0022] Compared with the traditional press-fit stud, the internal thread 31 of this press-fit stud is replaced by four sets of tube segments 3. These four sets of tube segments 3 are evenly distributed along the arc contour of the stud body 1. The internal threads 31 of these tube segments are the same set and have connectivity for subsequent connection. The sealing rings 5 on the tube segments 3 are used to increase the sealing strength and sealing performance of other parts in the subsequent connection steps. Unlike the traditional press-fit screw, the tube segments 3 have external threads 32 on their outer side. An adjustable ring 2 is threaded onto the external threads 32. The main function of the adjustable ring 2 is to move up and down with the external threads 32 on the outer side of the tube segments 3 to adjust the inner diameter of the circular tube formed by the four sets of tube segments 3, so as to achieve adjustable connection and adjustable connection tightness, and at the same time, it can also achieve the function of reinforcing the connection.
[0023] The outer diameter of the adjustable ring 2 is smaller than the riveting portion on the stud body 1 so that the stud body 1 can enter the workpiece to be riveted, and its riveting process is not affected.
[0024] like Figure 2 As shown, the adjustable ring 2 has an internal thread 22 on its inner diameter;
[0025] The pitch and major and minor diameters of the internal thread 22 are consistent with those of the external thread 32, which is used to better connect the adjustable ring 2 and the tube segment 3.
[0026] A limiting stage 11 is provided on the stud body 1;
[0027] The limiting platform 11 is designed to provide the minimum range of movement of the adjustable ring 2 on the stud body 1, that is, to provide it with a carrier for operation.
[0028] The segment 3 is provided with a certain degree of inclination.
[0029] The tube segment 3 is tilted at a certain angle outward from the center line of the stud body 1. When the adjustable ring 2 moves upward, it can squeeze the four sets of tube segments 3 toward the central axis, thereby adjusting the tightness of the connecting parts connected inside.
[0030] The four groups of segments 3 have a movable gap 6 between them;
[0031] The clearance 6 is used to provide a certain amount of space for movement when the segment 3 tilts inward, making the structure more stable and reliable.
[0032] The upper end of the tube segment 3 is provided with a sealing groove (not shown in the figure), and the sealing ring 5 is installed in the sealing groove;
[0033] The groove opening of the upper oil flow gap of the sealing groove is smaller than the diameter of the sealing ring 5, so that the sealing ring 5 is not easy to fall off after being installed in the sealing groove, thus enhancing the stability of the sealing connection.
[0034] The adjustable ring 2 is provided with an anti-slip rubber ring 21 to facilitate tightening by the operator;
[0035] In summary, by setting a sealing ring 5 on the tube segment 3, the sealing strength and sealing performance of other parts are increased in the subsequent connection steps. The adjustable ring 2, which is threadedly connected to the external thread 32, can move up and down with the external thread 32 on the outside of the tube segment 3 to adjust the inner diameter of the circular tube formed by the four tube segments 3, so as to achieve adjustable connection and adjustable connection tightness. At the same time, it can also achieve the function of reinforcing the connection, thereby achieving the effect of adjustable sealing connection of the press-fit stud.
[0036] The above description is merely a preferred embodiment of this application. The scope of protection of this application is not limited to the above embodiments. All technical solutions within this concept are within the scope of protection of this application. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of this application should also be considered within the scope of protection of this application.
