Description

Technical Field

[0001] The utility model relates to the technical field of studs, in particular to a full-thread stud which is anti-loosening. Background Art

[0002] Fastening studs are commonly used fasteners in reactors, which are generally composed of studs and nuts. In a long-term vibrating working environment, simply tightening the studs and nuts is prone to fastening failure, and in severe cases, they may become loose or even fall off. In addition, long-term vibration and excessive shear force can easily cause cracks and breakage in the studs, causing the equipment to be unable to operate safely, posing a major safety hazard.

[0003] The publication (announcement) number is CN201391525Y, which discloses a stud connector fastened with a cone-end screw. In the stud connector, fastening grooves are provided on the threaded columns at both ends of the stud. An inner thread hole is provided in the wall of the nut. When the inner thread hole is spirally connected with a slotted cone-end set screw, the nut and the stud are tightly locked. The stud connector fastened with a cone-end screw of the utility model can prevent the nut from loosening and falling off due to long-term vibration caused by mechanical power when used in the connection of mechanical parts, thereby avoiding safety accidents. The connector of the utility model can be suitable for right-handed or left-handed stud connectors.

[0004] Although the above scheme can prevent the nut from loosening and falling off on the stud, it only restricts the nut by pressing the cone-end screw against the fixing groove on the outer peripheral surface of the stud. The cone-end screw and the limiting nut are easy to separate from the stud as a whole. The stability of the limiting component for preventing the equipment from falling off is general, and the limiting component is also easy to get stuck through the threaded assembly adjustment, affecting the disassembly and assembly. For this reason, we propose a full-thread stud that prevents loosening. Utility Model Content

[0005] The main purpose of the utility model is to provide a fully threaded stud that prevents loosening. By setting an adjustment and storage component and a limit component, the utility model solves the problems that the limit components used to prevent equipment from falling off are generally stable and the limit components are easily stuck through threaded assembly and adjustment, which affects disassembly and assembly.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions: a fully threaded stud that prevents loosening, comprising a stud body with a hollow interior and a nut threadedly connected to the outer peripheral surface of the stud body, and also comprising: a mobilization and storage component and a limit component arranged on the stud body;

[0007] The mobilization and storage assembly includes a bearing disc, an adjustment screw, a connecting bearing and a storage box, wherein the bearing disc is fixedly arranged on the inner wall of one end of the stud body, the adjusting screw is threadedly connected to the center of the side of the bearing disc, the connecting bearing is fixedly sleeved on one end of the adjusting screw, the storage box is fixedly arranged on the end face of the connecting bearing, and a strip-shaped through groove is opened on the outer peripheral surface of one end of the stud body away from the bearing disc;

[0008] The limiting assembly includes a partition, a positioning through hole, a support spring and a limiting sleeve. The partition is fixedly arranged on the inner wall of the middle end of the storage box. A positioning through hole is respectively opened at the center of the two opposite sides of the storage box. One end of the support spring is connected to the center of the side of the partition. The limiting sleeve is fixedly arranged at the other end of the support spring. The limiting sleeve passes through the positioning through hole and the strip groove and extends to the outside of the stud body.

[0009] Preferably, the adjusting screw and the stud body are located on the same vertical central axis.

[0010] Preferably, there are two support springs in total and they are symmetrically arranged on the vertical center horizontal plane of the storage box, and the limiting sleeves and the support springs are arranged in a one-to-one correspondence.

[0011] Preferably, the limiting sleeve and the adjusting screw are arranged perpendicular to each other.

[0012] Preferably, an annular groove is formed on one side surface of the bearing disc and is located outside the adjusting screw. An annular rubber ring is fixedly provided on the side of the adjusting screw head and extends movably into the annular groove and is located outside the adjusting screw.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. In the utility model, by arranging a mobilization and storage assembly, a limit assembly composed of components such as a supporting spring can be retracted as a whole into a storage box at the end of the adjusting screw, and a connecting bearing can prevent the storage box from rotating with the adjusting screw all the time. By operating and rotating the adjusting screw, the adjusting screw threadedly connected to the center of the side of the bearing disc and located inside the stud body can help the storage box and the limit assembly to translate and adjust as a whole but will not separate from the stud body. After the storage box is mobilized to avoid the strip through groove on the outer peripheral surface of one end of the stud body, the nut loses its obstruction and can be disassembled and assembled on the stud body. After the storage box is mobilized to enter the inner side of the strip through groove, the limit assembly can operate to limit the nut, and the limit assembly for preventing the equipment from falling off is flexible and has high stability.

[0015] 2. In the utility model, a limit assembly is provided, and by pressing the limit sleeve, the support spring is compressed and matched with the limit sleeve to be retracted into the storage box through the positioning through hole. The limit assembly can be moved with the storage box to avoid the strip through groove on the outer peripheral surface of one end of the stud body. After the storage box is moved into the inner side of the strip through groove, the support spring connected to the center of the side of the partition at one end loses its obstruction and deformation and expansion can help the limit sleeve to pass through the positioning through hole and the strip through groove and finally extend to the outside of the stud body. The limit sleeve can block the limit nut outside the stud body, and the limit assembly for preventing the equipment from falling off works stably and smoothly, which can ensure the smooth removal of the nut.
