Description

Technical Field

[0001] This application relates to the field of press-fit post technology, and in particular to a stable press-fit post. Background Technology

[0002] A press-fit pin is a fastener in which a head of a specific shape is pressed into a pre-drilled hole in a thin plate using a press machine, causing plastic deformation around the hole and fixing it to the thin plate.

[0003] According to announcement number CN207989494U, a press-fit stud is disclosed. This technology discloses a technical solution that includes "a press-fit component, a threaded component, and a connector. The press-fit component has a press-fit portion and a first sleeve portion axially disposed on the press-fit portion. The threaded component includes a threaded portion and a second sleeve portion that are interconnected and disposed at both ends axially. The first sleeve portion and the second sleeve portion are axially movably sleeved relative to each other. The connector is detachably connected to the first sleeve portion and the second sleeve portion." This solution has the technical effect that the sleeve length of the first sleeve portion and the second sleeve portion can be adjusted by the connector. When the sleeve length of the first sleeve portion and the second sleeve portion is changed, the specification of the entire press-fit stud will change accordingly. Thus, a single press-fit stud can accommodate different specifications, making it convenient to use.

Detailed Implementation

[0030] The following is in conjunction with the appendix Figure 1 -Attached Figure 3 This application will be described in further detail below.

[0031] Example

[0032] A stable type of press-fit post, reference Figure 1 and Figure 2 The device includes a rivet cap 1, a rivet mechanism 2 fixedly installed on one side of the rivet cap 1, the rivet mechanism 2 is for making the rivet more stable, an expansion mechanism 3 is installed inside the rivet mechanism 2, the expansion mechanism 3 is for secondary limiting after rivet, the rivet mechanism 2 includes a rivet cylinder 20, and one end of the rivet cylinder 20 is fixed to one side of the rivet cap 1 by welding, a plurality of tooth blocks 22 that cooperate with the rivet cap 1 are fixedly welded on the outer surface of the rivet cylinder 20, and a relief groove 21 that cooperates with the rivet cap 1 is opened on the outer surface of the rivet cylinder 20.

[0033] Reference Figure 2 The outer surface of the rivet cap 1 has multiple grooves 23, which are evenly distributed on the outer surface of the rivet cap 1. The outer surface of the rivet cylinder 20 is fixed with an anti-slip layer 24 by adhesive. Multiple toothed blocks 22 are distributed in a ring on the outer surface of the rivet cylinder 20, and one side of each toothed block 22 is fixed to one side of the rivet cap 1 by welding. The grooves 23 can prevent the rivet cap 1 from moving in the hole after riveting. The anti-slip layer 24 can prevent the rivet cylinder 20 from slipping when the worker places it for riveting. The ring distribution of the toothed blocks 22 can effectively improve the stability of the rivet post after riveting.

[0034] Reference Figure 3 The expansion mechanism 3 includes an expansion rod 30, an expansion nut 32 is welded and fixed on one side of the expansion rod 30, a threaded strip 33 is welded on the outer surface of the expansion rod 30 to cooperate with the rivet cylinder 20 and the rivet nut 1, and an expansion groove 36 is opened on the inner surface of the rivet cylinder 20 to cooperate with the expansion rod 30.

[0035] Reference Figure 3 The expansion nut 32 has an installation groove 31 on one side, and the inner surface of the rivet cylinder 20 has a rotating groove 34, and the inner surface of the rotating groove 34 slides and fits against the outer surface of the expansion rod 30. The rivet cap 1 has a threaded groove 35 on one side, and the inner surface of the threaded groove 35 threadedly fits against the outer surface of the threaded strip 33. The expansion nut 32 can be rotated quickly and easily through the installation groove 31. The expansion rod 30 can slide on the inner surface of the rotating groove 34 through the rotating groove 34, and the threaded strip 33 can rotate on the inner surface of the threaded groove 35 through the threaded groove 35.

[0036] The implementation principle of this application embodiment is as follows: the riveting cylinder 20 and the riveting cap 1 are placed in the reserved hole through the riveting mechanism 2, and then the riveting equipment squeezes the riveting cap 1 from above, so that when the metal plate is deformed by the squeeze, it will be squeezed into the relief groove 21 for limiting, and the stability after riveting can be further improved by the tooth block 22, thereby achieving the purpose of riveting the riveting column to be effectively riveted and fixed.

[0037] The rivet cap 1 can be prevented from moving in the hole after riveting through the groove 23. The rivet cylinder 20 can be prevented from slipping when the worker places it for riveting through the anti-slip layer 24. The toothed blocks 22 are distributed in a ring, which can effectively improve the stability of the rivet post after riveting.

[0038] The expansion rod 30 is inserted into the riveting cylinder 20 through the expansion mechanism 3. By rotating the expansion nut 32, the threaded strip 33 on the outer surface of the expansion rod 30 can rotate on the inner surface of the threaded groove 35. This allows the threaded strip 33 to drive the expansion rod 30 and the expansion nut 32 to move. The expansion nut 32 can then squeeze the riveting cylinder 20, causing the riveting cylinder 20 to deform and expand in conjunction with the expansion groove 36. This allows the expansion groove 36 to expand and deform on the other side of the metal plate, thus achieving the purpose of effectively limiting the riveting post after riveting.

[0039] The expansion nut 32 can be rotated quickly and easily through the mounting groove 31, the expansion rod 30 can slide on the inner surface of the rotating groove 34 through the rotating groove 34, and the threaded strip 33 can rotate on the inner surface of the threaded groove 35 through the threaded groove 35.
