Description

Technical Field

[0001] This utility model relates to the field of fastener technology, and more specifically, to a riveting shaft and a photovoltaic panel. Background Technology

[0002] A riveting shaft is a commonly used fastener. Riveting, or rivet connection, is a mechanical term referring to a method of connecting multiple parts by using axial force to thicken the rivet shank inside the rivet hole and form a rivet head. Current riveting methods involve directly pressing the rivet into the riveting shaft. However, this method often results in uneven pressing of the rivet, leading to an unstable connection and potential safety hazards. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a riveting shaft and a photovoltaic panel, which has the advantage of uniform rivet stamping.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a riveting shaft, comprising a riveting shaft, a threaded hole being provided at the middle end of the inner cavity of the riveting shaft, a limiting ring being provided in the inner cavity of the riveting shaft, a screw being engaged in the inner cavity of the threaded hole, a restraining ring being fixedly installed at the rear end of the inner cavity of the riveting shaft, and a rubber groove one and a rubber groove two being provided on the front side of the riveting shaft, a rubber ring two being installed inside the rubber groove one, and a rubber ring one being installed inside the rubber groove two.

[0005] As a preferred embodiment of this utility model, a support block is fixedly installed on the outer side of the riveting shaft, and the four support blocks are distributed at equal angles around the axis of the riveting shaft.

[0006] In a preferred embodiment of this invention, both rubber ring one and rubber ring two are annular, and the diameter of rubber ring two is larger than that of rubber ring one.

[0007] In a preferred embodiment of this invention, the screw passes through the limiting ring and is fixed in the inner cavity of the riveting shaft, and the limiting ring is triangular in shape.

[0008] In addition, this utility model also provides a photovoltaic panel, wherein a fixing plate is fixedly installed at the rear end of the photovoltaic panel, a support plate one is fixedly installed at the front end of the fixing plate, a support plate two is fixedly installed at the rear end of the fixing plate, and a rivet is fixedly installed at the rear end of the photovoltaic panel, the rivet being inserted into a riveting shaft.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. This utility model first places the limiting ring into the inner cavity of the riveting shaft, then inserts the screw through the limiting ring into the threaded hole and tightens the threaded hole. Then, the rivet at the rear end of the photovoltaic panel passes through the fixing plate, and then the riveting shaft passes through the rivet. After that, a punch is used to punch one end of the rivet that passes through the riveting shaft. At the same time, the rivet is punched more tightly by the shape of the limiting ring and the restraint ring inside the riveting shaft, thereby achieving a more uniform punching effect.

[0011] 2. In this utility model, rubber ring 1 and rubber ring 2 installed at the front end of the riveting shaft are stamped during the stamping process. The stamping force evenly compresses rubber ring 1 and rubber ring 2 to form a sealing ring, thereby achieving the sealing effect. Attached Figure Description

[0019] 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.

[0020] like Figures 1 to 6As shown, this utility model provides a riveting shaft, including a riveting shaft 6. A threaded hole 7 is provided at the middle end of the inner cavity of the riveting shaft 6. A limiting ring 8 is provided in the inner cavity of the riveting shaft 6. A screw 9 is engaged in the inner cavity of the threaded hole 7. A restraining ring 10 is fixedly installed at the rear end of the inner cavity of the riveting shaft 6. A rubber groove 11 and a rubber groove 2 12 are provided on the front side of the riveting shaft 6. A rubber ring 2 14 is installed inside the rubber groove 11, and a rubber ring 13 is installed inside the rubber groove 2 12.

[0021] First, the limiting ring 8 is placed into the inner cavity of the riveting shaft 6. Then, the screw 9 is inserted through the limiting ring 8 into the threaded hole 7 and tightened. Next, the rivet 5 at the rear end of the photovoltaic panel 1 is passed through the fixing plate 2. Then, the riveting shaft 6 is passed through the rivet 5. After that, a punch is used to punch one end of the rivet 5 that passes through the riveting shaft 6. At the same time, the rivet 5 will be more tightly punched by the limiting ring 8 and the restraining ring 10 inside the riveting shaft 6, thereby achieving a more uniform punching effect.

[0022] Among them, a support block 15 is fixedly installed on the outer side of the riveting shaft 6, and four support blocks 15 are distributed at equal angles around the axis of the riveting shaft 6.

[0023] The four support blocks 15 are distributed at equal angles around the axis of the riveting shaft 6 to make the force distribution at the front end of the riveting shaft 6 more uniform.

[0024] Among them, rubber ring 13 and rubber ring 2 14 are both annular, and the diameter of rubber ring 2 14 is larger than that of rubber ring 13.

[0025] The reason why both rubber ring 13 and rubber ring 2 14 are circular and rubber ring 2 14 is larger than rubber ring 13 is that the difference in size between the two results in a better seal.

[0026] The screw 9 passes through the limiting ring 8 and is fixed in the inner cavity of the riveting shaft 6. The limiting ring 8 is triangular in shape.

[0027] The triangular shape of the limiting ring 8 allows the rivets 5 to be distributed more evenly when they are stamped.

[0028] In addition, this utility model also provides a photovoltaic panel, wherein a fixing plate 2 is fixedly installed at the rear end of the photovoltaic panel 1, a support plate 3 is fixedly installed at the front end of the fixing plate 2, a support plate 4 is fixedly installed at the rear end of the fixing plate 2, and a rivet 5 is fixedly installed at the rear end of the photovoltaic panel 1, the rivet 5 being inserted into the riveting shaft 6.

[0029] The photovoltaic panel 1 can be more firmly fixed by installing a support plate 3 at the front end of the fixing plate 2 and a support plate 4 at the rear end of the fixing plate 2.

[0030] The working principle and usage process of this utility model are as follows: During connection, first install rubber ring 13 and rubber ring 2 14 into rubber groove 11 and rubber groove 2 12 at the front end of the riveting shaft 6. Then place the limiting ring 8 into the inner cavity of the riveting shaft 6. Next, insert the screw 9 through the limiting ring 8 into the threaded hole 7 and tighten the threaded hole 7 to fix the limiting ring 8 in the inner cavity of the riveting shaft 6. Then, pass the rivet 5 installed at the rear end of the photovoltaic panel 1 through the fixing plate 2. Then, pass the riveting shaft 6 through the rivet 5. Next, use a punch to punch one end of the rivet 5 that passes through the riveting shaft 6. During punching, the rivet 5 will be punched more evenly and tightly according to the shape of the limiting ring 8 and the restraint of the restraint ring 10. The rubber ring 13 and rubber ring 2 14 fixed at the front end of the riveting shaft 6 will be squeezed to form a sealing ring during punching. After punching is completed, the punch can be removed.
