Internal rotation type rivet

Abstract

This utility model discloses an internally rotating rivet, relating to the field of rivets. It includes a rivet disc, with a rivet sleeve fixedly connected to the bottom of the disc, and a fixed disc fixedly connected inside the disc. A rivet shank is threadedly connected to the inside of the fixed disc. This utility model, by setting a reinforcing sleeve and a slot, allows the rivet sleeve to be inserted into the rivet hole. A tool then rotates the rivet shank, causing it to rotate and move the threaded sleeve upwards, deforming it. As the threaded sleeve moves upwards, it moves the reinforcing sleeve upwards, allowing it to enter the slot. The rivet shank is then rotated again, causing it to move downwards. The rotating disc compresses the reinforcing sleeve inserted into the slot, deforming it and connecting the threaded sleeve and the fixed disc into a single unit. This improves the overall strength of the internally rotating rivet and enhances its practicality.

Description

Technical Field

[0001] This utility model relates to the field of rivets, and in particular to an internally rotating pull rivet. Background Technology

[0002] Rivets include open-type blind rivets, closed-type rivets, ring groove rivets, and internal screw rivets. Due to their simplicity and practicality, rivets are usually used to fix some sheet metal or small parts.

[0003] Most existing internal screw rivets rely on the rotation of the threaded sleeve during use, causing it to move inside the rivet sleeve and deform, thus securing the sheet metal. However, relying solely on the deformed rivet sleeve and rivet disc for securing the sheet metal results in poor fixing performance and easy loosening over time, thereby reducing the practicality of the rivet.

[0004] Therefore, it is necessary to propose an internally rotating rivet to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an internally rotating rivet to solve the problem mentioned in the background art that the fixation of plates relies solely on deformed rivet sleeves and rivet discs, resulting in poor fixing effect and easy loosening over time, thereby reducing the practicality of the rivet.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an internally rotating rivet, comprising a rivet disc, a rivet sleeve fixedly connected to the bottom of the rivet disc, a fixed disc fixedly connected inside the rivet disc, a rivet rod threadedly connected inside the fixed disc, a rotating disc fixedly connected to the top of the rivet rod, and a threaded sleeve threadedly connected inside the rivet sleeve.

[0007] A reinforcing sleeve is fixedly connected to the top of the threaded sleeve, and a slot is provided inside the fixed plate, the diameter of which is larger than the diameter of the reinforcing sleeve.

[0008] Preferably, there are two reinforcing sleeves, and the two reinforcing sleeves are located on one side and the other side of the rivet rod, respectively.

[0009] Preferably, the reinforcing sleeve has a deformation groove inside.

[0010] Preferably, the outside of the rivet rod is threadedly connected to the inside of the threaded sleeve.

[0011] Preferably, a cross groove is formed inside the top of the rotating disk.

[0012] Preferably, the top of the rivet disc has a placement groove.

[0013] The technical effects and advantages of this internally rotating rivet:

[0014] 1. By setting up a reinforcing sleeve and a slot, after the rivet sleeve is inserted into the rivet hole, the tool drives the rivet rod to rotate. The rotation force of the rivet rod will drive the threaded sleeve to move upward, causing the rivet sleeve to deform. The rivet disc and the deformed rivet sleeve are used to fix the plate. When the threaded sleeve moves upward, it will drive the reinforcing sleeve to move upward, so that the reinforcing sleeve enters the interior of the slot. Then, the rivet rod is rotated again, causing the rivet rod to move downward. The rotating disc is used to squeeze the reinforcing sleeve inserted into the slot, causing the reinforcing sleeve to deform. This connects the threaded sleeve and the fixed disc into a whole, improving the overall strength of the internal spiral rivet and thus improving the practicality of the internal spiral rivet.

[0015] 2. By setting deformation grooves, when the rotating disk moves downwards to squeeze the reinforcing sleeve, the top of the reinforcing sleeve will first deform to both sides of the reinforcing sleeve through the deformation grooves, forming a stop block larger than the diameter of the slot, which facilitates the deformation of the reinforcing sleeve and brings convenience to the operation of the internal rotating rivet.

[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] This utility model provides, for example Figure 1 - Figure 4 The internally rotating rivet shown includes a rivet disc 1, a rivet sleeve 2 fixedly connected to the bottom of the rivet disc 1, and a fixed disc 3 fixedly connected inside the rivet disc 1. A rivet rod 5 is threadedly connected inside the fixed disc 3, and a rotating disc 6 is fixedly connected to the top of the rivet rod 5. A threaded sleeve 4 is threadedly connected inside the rivet sleeve 2, and a reinforcing sleeve 7 is fixedly connected to the top of the threaded sleeve 4. A slot 9 is provided inside the fixed disc 3, and the diameter of the slot 9 is larger than the diameter of the reinforcing sleeve 7. There are two reinforcing sleeves 7, and the two reinforcing sleeves 7 are located on one side and the other side of the rivet rod 5, respectively. A deformation groove 8 is provided inside the reinforcing sleeve 7. The outside of the rivet rod 5 is threadedly connected to the inside of the threaded sleeve 4. After the rivet sleeve 2 is inserted into the rivet hole, the tool drives the rivet rod 5 to rotate. The rotation force of the rivet rod 5 causes the threaded sleeve 4 to move upward, causing the rivet sleeve 2 to deform. The rivet disc 1 and the deformed rivet sleeve 2 are used to fix the plate. When the threaded sleeve 4 moves upward, it will drive the reinforcing sleeve 7 to move upward, so that the reinforcing sleeve 7 enters the interior of the slot 9. Then, the rivet rod 5 is rotated again, causing the rivet rod 5 to move downward. The rotating disc 6 is used to squeeze the reinforcing sleeve 7 inserted into the slot 9, causing the reinforcing sleeve 7 to deform. This connects the threaded sleeve 4 and the fixing disc 3 into a whole, improving the overall strength of the internal spiral rivet and thus improving the practicality of the internal spiral rivet.

[0024] When the rotating disk 6 moves downwards and presses against the reinforcing sleeve 7, the top of the reinforcing sleeve 7 first deforms towards both sides through the deformation groove 8, forming a stop larger than the diameter of the slot 9. This facilitates the deformation of the reinforcing sleeve 7 and makes the operation of the internally rotating rivet more convenient.

[0025] Finally, a cross groove is formed inside the top of the rotating disk 6, and a placement groove is formed on the top of the rivet disk 1. The cross groove facilitates the rotation of the rivet rod 5, and the placement groove facilitates the placement of the rotating disk 6, ensuring that the rotating disk 6 does not protrude from the surface of the rivet disk 1, thus facilitating the use of internally rotating pull rivets.

[0026] Working principle: When the rivet sleeve 2 is inserted into the rivet hole, the tool drives the rivet rod 5 to rotate. The rotation force of the rivet rod 5 drives the threaded sleeve 4 to move upward, causing the rivet sleeve 2 to deform. The rivet disc 1 and the deformed rivet sleeve 2 are used to fix the plate. When the threaded sleeve 4 moves upward, it drives the reinforcing sleeve 7 to move upward, so that the reinforcing sleeve 7 enters the interior of the slot 9. Then, the rivet rod 5 is rotated again, causing the rivet rod 5 to move downward. The rotating disc 6 compresses the reinforcing sleeve 7 inserted into the slot 9, causing the reinforcing sleeve 7 to deform. This connects the threaded sleeve 4 and the fixing disc 3 into a whole, improving the overall strength of the internal spiral rivet and thus improving the practicality of the internal spiral rivet. When the rotating disk 6 moves downward and squeezes the reinforcing sleeve 7, the top of the reinforcing sleeve 7 will first deform to both sides of the reinforcing sleeve 7 through the deformation groove 8, forming a block larger than the diameter of the slot 9, which facilitates the deformation of the reinforcing sleeve 7 and brings convenience to the operation of the internal rotating rivet.
