Description

Technical Field

[0001] The utility model relates to the field of bolt design, in particular to an adjustable bolt. Background Art

[0002] During the use of existing bolts, the bolts need to be installed into the threaded grooves inside the objects to achieve the installation and fixation of the objects. However, the installation holes of common objects have different depths. When objects of multiple different depths need to be installed and fixed, the staff needs to frequently replace and install the bolts according to the installation holes of different depths, which makes the object installation steps more cumbersome, which reduces the work efficiency of the staff to a certain extent. Utility Model Content

[0003] The purpose of the utility model is to provide an adjustable bolt in order to solve the above-mentioned problem. By separating the main bolt from the rotating structure, the rotating structure drives the connecting bolt to rotate inside the object through the block and the groove on the connecting structure, thereby extending the length of the bolt.

[0004] The utility model achieves the above-mentioned purpose through the following technical scheme: an adjustable bolt, comprising a bolt body, a connecting bolt and a rotating structure, the bolt body and the connecting bolt are connected to each other through a telescopic structure, the bolt body and the rotating structure are connected to each other through a clamping structure, the rotating structure and the connecting bolt are connected to each other through a connecting structure, the rotating structure comprises a rotating rod and a sliding rod, an extrusion cylinder is fixedly arranged at the lower end of the rotating rod, the connecting structure comprises two sliding blocks and two sliding grooves, the sliding block is fixedly arranged on the front side of the sliding rod, the sliding groove is opened on the front side of the interior of the connecting bolt, the sliding block is slidably arranged inside the sliding groove, and a first spring is fixedly connected between the sliding block and the sliding groove.

[0005] Furthermore, the telescopic structure includes a connecting ring and an expansion sleeve, the expansion sleeve is fixedly arranged at the lower end of the bolt body, a telescopic rod is fixedly arranged at the opening of the expansion sleeve, and the connecting ring is rotatably connected to the upper end of the connecting bolt.

[0006] Furthermore, a second spring is fixedly connected inside the telescopic rod, and the connecting ring is fixedly arranged at the lower end of the telescopic rod.

[0007] Furthermore, a rubber pad is fixedly provided on the outer side of the rotating rod near the lower end.

[0008] Furthermore, the extrusion cylinder is fixedly arranged on the upper end of the sliding rod.

[0009] Furthermore, a connecting cylinder is rotatably arranged inside the bolt body.

[0010] Furthermore, the clamping structure includes a clamping block and a clamping slot, wherein the clamping block is fixedly arranged inside the bolt body near the front and rear, and the clamping slot is arranged inside the extrusion cylinder near the front.

[0011] Furthermore, the card block is arranged in a card slot.

[0012] With the above structure, when using the device, first, the bolt body is rotated to connect through the internal thread of the object. When the bolt is short, the turning rod is moved downward, and then the extrusion cylinder on the turning rod is separated from the clamping structure between the bolt body, and then the turning rod is rotated, and then the sliding rod on the extrusion cylinder is moved, so that the extrusion cylinder drives the connecting bolt to rotate according to the slider on the connecting structure. At the same time, when the connecting bolt moves along the internal thread of the object, the slider moves up and down inside the slide groove, and when the turning rod moves downward, the extrusion cylinder on the turning rod squeezes the expansion sleeve.

[0013] In summary, the beneficial effect of the utility model is that the rotating rod is moved downward, so that the block on the bolt body is separated from the groove on the extrusion cylinder, so that the connecting bolt and the bolt body are separated. When the rotating rod is rotated, the rotating rod drives the sliding rod on the extrusion cylinder to rotate, and the sliding rod drives the connecting bolt to rotate and move up and down through the connecting structure, which makes it convenient for the connecting bolt to move along the internal thread of the object, and can be adjusted according to the depth of the internal thread groove of the object, which improves the installation efficiency of the staff to a certain extent.
