Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rivet structures, in particular to a back-stop rivet structure. Background Art
[0002] A rivet is a nail-shaped object with a cap at one end. During riveting, it uses its own deformation or interference fit to connect the riveted parts. There are many types of rivets, and they are not restricted by form. Commonly used ones include semi-circular head, flat head, semi-hollow rivets, solid rivets, countersunk rivets, blind rivets, and hollow rivets. These usually use their own deformation to connect the riveted parts.
[0003] Although the existing rivets can play the role of riveting, they are not provided with a locking and stopping combination. After riveting, the rivet body and the rivet sleeve are prone to loosening and separation. In addition, the existing rivet structure has complicated steps for disassembly. Most of them require damage to the rivet structure for disassembly, which is easy to damage the riveted object. Utility Model Content
[0004] The utility model aims to provide a stop rivet structure to solve the problems raised in the above background technology.

[0006] Preferably, an extension column is provided at the bottom end of the upper push plate, and a spring is provided on the outer surface of the extension column. The extension column supports the inside of the spring to ensure that the spring will not be skewed when compressed by force, so that the center column can move linearly and prevent internal parts from getting stuck.
[0007] Preferably, a column is provided at the bottom of the locking frame, and both ends of the column are movably connected to the inside of the rivet body. The locking frame is installed in a predetermined position through the column, so that the locking frame can be flipped around the center of the column, and the bottom of the locking frame extends to one side between the upper push plate and the lower pressure plate. When the lower pressure plate presses down on the lower part of the locking frame, the locking frame is flipped toward the direction of the rivet body and stored in the inside of the rivet body, so that the rivet can pass through the preset hole, and when the upper push plate pushes the bottom of the locking frame upward, the locking frame flips outward and gets stuck at the bottom of the object to achieve a stopping effect.
[0008] Preferably, the top end of the spring is fixedly connected to the bottom surface of the upper push plate, and the bottom end of the top end of the spring is fixedly connected to the inner surface of the rivet body, fixing the spring in a predetermined position. When the center column is pressed, the spring can contract when squeezed, and when the center column is released, the spring will push the upper push plate to quickly reset the center column.
[0009] Preferably, a limit block is provided at the top of the rivet body, and a force ring is provided at the top of the limit block. The limit block can limit the upward movement trajectory of the nut to prevent the nut from falling off. When installing the rivet, the force ring can be pressed down to allow the rivet to pass through the preset hole.
[0010] Preferably, a cavity is provided inside the rivet body on the outer surface of the extension column, so that the extension column can perform a linear movement downward for a distance, ensuring that the lower pressure plate can press down the lower part of the locking frame.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.
[0020] like Figures 1 to 3 As shown, the present embodiment is a kind of back-off rivet structure, including a rivet body 1, the outer surface of the rivet body 1 is provided with a thread groove 6, the outer surface of the thread groove 6 is threadedly connected with a nut 5, so that the nut 5 can perform linear motion in the vertical direction while rotating, and the outer surface of the rivet body 1 below the thread groove 6 is provided with a notch 13, and a locking frame 7 is arranged on the notch 13, and the locking frame 7 can be received in the notch 13, so that the rivet body 1 can pass through the preset hole, and the interior of the rivet body 1 is provided with a center column 2, and the rivet body 1 extends out from the top of the center column 2, and the bottom end surface of the center column 2 is provided with a lower pressure plate 9, and the lower pressure plate 9 can be driven by the center column 2 to perform linear motion in the vertical direction, and the bottom end of the lower pressure plate 9 is provided with a pad column 10, which separates the upper push plate 8 and the lower pressure plate 9 so that there is a certain space between the two, and the bottom end of the pad column 10 is provided with an upper push plate 8.
[0021] Specifically, an extension column 12 is provided at the bottom end of the upper push plate 8, and a spring 11 is provided on the outer surface of the extension column 12. The extension column 12 supports the inside of the spring 11 to ensure that the spring 11 will not be skewed when subjected to force compression, so that the center column 2 can perform linear motion and prevent internal parts from getting stuck.
[0022] Furthermore, a column 14 is provided at the bottom of the locking frame 7, and both ends of the column 14 are movably connected to the inside of the rivet body 1. The locking frame 7 is installed at a predetermined position through the column 14, so that the locking frame 7 can be flipped around the center of the column 14, and the bottom of the locking frame 7 extends to one side between the upper push plate 8 and the lower pressure plate 9. When the lower pressure plate 9 presses down on the lower part of the locking frame 7, the locking frame 7 is flipped toward the rivet body 1 and stored in the inside of the rivet body 1, so that the rivet can pass through the preset hole, and when the upper push plate 8 pushes the bottom of the locking frame 7 upward, the locking frame 7 flips outward and gets stuck at the bottom of the object to achieve a stopping effect.
[0023] Furthermore, the top end of the spring 11 is fixedly connected to the bottom surface of the upper push plate 8, and the bottom end of the top end of the spring 11 is fixedly connected to the inner surface of the rivet body 1, fixing the spring 11 in a predetermined position. When the center column 2 is pressed, the spring 11 can shrink when squeezed, and when the center column 2 is released, the spring 11 will push the upper push plate 8 to quickly reset the center column 2.
[0024] Furthermore, a limit block 4 is provided at the top of the rivet body 1, and a force ring 3 is provided at the top of the limit block 4. The limit block 4 can limit the upward movement trajectory of the nut 5 to prevent the nut 5 from falling off. When installing the rivet, the force ring 3 can be pressed down to allow the rivet to pass through the preset hole.
[0025] Furthermore, a cavity 15 is provided inside the rivet body 1 on the outer surface of the extension column 12 , so that the extension column 12 can perform a linear movement downward for a distance, ensuring that the lower pressure plate 9 can press down the lower part of the locking frame 7 .
[0026] The method of using this embodiment is as follows: when using the rivet, press down the center column 2 to make the lower pressure plate 9, and the lower pressure plate 9 presses down the lower part of the locking frame 7, and the locking frame 7 is flipped toward the rivet body 1 and stored in the rivet body 1, and then the rivet is passed through the preset hole, and then the center column 2 is loosened. At this time, the spring 11 releases the pressure and pushes the upper push plate 8 upward. The upper push plate 8 pushes the bottom of the locking frame 7. At this time, the locking frame 7 is flipped outward and opened to clamp the bottom end of the object, and then the nut 5 is twisted. The nut 5 moves linearly toward the object to be fixed, so that the nut 5 is stuck at the top of the object to play a stopping effect. If the rivet needs to be removed, twist the nut first to make the nut 5 leave the top of the object, and then press the lower center column 2, and the lower pressure plate 9 presses down the lower part of the locking frame 7, so that the locking frame 7 is stored in the slot 13 opened in the rivet body 1, and the rivet can be pulled out at the same time.
[0027] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
