Description

Technical Field

[0001] This utility model relates to the field of fastener technology, specifically to an adjustable rivet assembly. Background Technology

[0002] In industrial production and daily life, rivets are a common type of fastener and are widely used for connecting various structures. Traditional rivets usually consist of a rivet head and a rivet shank. By inserting the rivet shank into the hole of the parts to be connected, the rivet shank is deformed using tools such as a rivet gun, thereby achieving a fastening connection.

[0003] However, traditional rivets have many limitations: on the one hand, their tightness and position are fixed after installation, making it difficult to adjust according to changes during actual use. For example, in mechanical assembly, due to machining errors of parts or deformation after long-term use, the tightening effect of traditional rivets may be unsatisfactory, but it is impossible to adjust on-site, and new rivets must be installed, increasing costs and workload. On the other hand, when it is necessary to make local adjustments to the connected structure or disassemble some parts, the fixed nature of traditional rivets makes the operation difficult and may even damage the connected parts. To address these issues, we propose an adjustable rivet assembly. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an adjustable rivet assembly, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: an adjustable rivet assembly for fastening connections between connectors, comprising: a rod body, a main rivet head, and a secondary rivet head that are inserted into the connectors together; a main nut is embedded in the inner wall of the main rivet head; an external thread for threaded connection with the main nut is provided on the outer surface of the rod body; the secondary rivet head can be sleeved with the rod body; a sealing block is provided at the lower end of the rod body passing through the secondary rivet head; a secondary nut and a positioning block are fixedly installed on the inner wall of the sealing block; a bolt is threadedly connected to the sealing block through the secondary nut; the bolt can also be threadedly connected to the rod body.

[0006] Preferably, an inner ring is fixedly installed on the outer surface of the main nut, and the inner ring is also embedded in the main nail head.

[0007] Preferably, both the main nail head and the auxiliary nail head are designed with a T-shaped structure, and in use, the main nail head and the auxiliary nail head are symmetrically arranged on both sides of the connector.

[0008] Preferably, a shrinkable cylinder is fixedly installed on the inner wall of the secondary nail head, and a gap is provided between the shrinkable cylinder and the rod body.

[0009] Preferably, the lower end of the rod is provided with a positioning groove, which can cooperate with the positioning block.

[0010] Preferably, after the sealing block is spliced ​​onto the lower end of the rod, the lower end face of the rod contacts the secondary nut.

[0011] Preferably, the size of the sealing block is larger than the size of the inner hole of the shrinkage cylinder.

[0012] Preferably, the lower end face of the rod is provided with a threaded hole, the axis of which coincides with the axis of the bolt.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This adjustable rivet assembly features a main rivet head and a secondary rivet head sequentially mounted on the rod. These two heads work together, and the threads on the rod surface engage with the main nut inside the main rivet head to reduce the distance between them. Because of the threaded connection, fine-tuning during installation or adjustments due to structural changes during use are easily achieved. On-site adjustment is possible, avoiding the need to reinstall the rivet due to installation errors or structural changes, thus reducing material waste and labor costs.

[0015] 2. This adjustable rivet assembly uses a sealing block at the end of the rod to attach the secondary rivet head to the rod. The user can also change the connection between the sealing block and the rod using bolts, thereby removing the secondary rivet head to facilitate the fastening of multiple connectors together.

[0022] 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.

[0023] Please see Figure 1-5 An adjustable rivet assembly for fastening connections between connectors 6 includes: a rod 1, a main rivet head 2, and a secondary rivet head 3, all inserted into the connectors 6. A main nut 4 is embedded in the inner wall of the main rivet head 2. An inner ring 41 is fixedly installed on the outer surface of the main nut 4, also embedded in the main rivet head 2. This ensures the stability between the main nut 4 and the main rivet head 2 after engagement, thus meeting practical usage requirements. The outer surface of the rod 1 is provided with external threads for threaded connection with the main nut 4. The nail head 3 can be sleeved with the rod body 1; both the main nail head 2 and the auxiliary nail head 3 are T-shaped structures. In use, the main nail head 2 and the auxiliary nail head 3 are symmetrically arranged on both sides of the connector 6. The inner wall of the auxiliary nail head 3 is fixedly installed with a shrink cylinder 31. A gap is provided between the shrink cylinder 31 and the rod body 1, so that the auxiliary nail head 3 can slide flexibly on the rod body 1. At the same time, the design of the shrink cylinder 31 can reduce the size of the gap and prevent the auxiliary nail head 3 from tilting during the sliding process, so as to ensure that the auxiliary nail head 3 can be inserted into the mounting hole on the connector 6.

[0024] A sealing block 5 is provided at the lower end of the rod body 1, which passes through the secondary nail head 3. A secondary nut 51 and a positioning block 53 are fixedly installed on the inner wall of the sealing block 5. The sealing block 5 is threadedly connected to a bolt 52 through the secondary nut 51. The bolt 52 can also be threadedly connected to the rod body 1. A positioning groove 54 is provided at the lower end of the rod body 1. The positioning groove 54 can cooperate with the positioning block 53. After the sealing block 5 is spliced ​​at the lower end of the rod body 1, the lower end face of the rod body 1 contacts the secondary nut 51. The size of the sealing block 5 is larger than the size of the inner hole of the shrink cylinder 31. This design can ensure that the sealing block 5 can restrict the secondary nail head 3 on the rod body 1, thereby cooperating with the main nail head 2 to connect multiple connectors 6. A threaded hole is provided at the lower end face of the rod body 1. The axis of the threaded hole coincides with the axis of the bolt 52 to ensure the fit of the bolt 52.

[0025] Working principle: The rod 1 is inserted into the mounting hole of the connector 6 to ensure that the main nail head 2 is in close contact with the surface of the connected part 6. Then, the auxiliary nail head 3 is inserted from the lower end of the rod 1. The positioning block 53 in the inner cavity of the sealing block 5 cooperates with the positioning groove 54 on the rod 1 to fit the sealing block 5 onto the lower end of the rod 1. Then, the bolt 52 cooperates with the auxiliary nut 51 inside the sealing block 5 and the threaded hole on the lower end face of the rod 1 to lock the sealing block 5 at the lower end of the rod 1. Then, the rod 1, which is threaded to the main nut 4 inside the main nail head 2, is rotated. The sealing block 5 drives the auxiliary nail head 3 to move upward, reducing the distance between the auxiliary nail head 3 and the main nail head 2, thereby completing the fastening connection between the connectors 6.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
