Description

Technical Field

[0001] The utility model relates to the technical field of bolt assemblies, and more specifically, to an adjustable bolt assembly. Background Art

[0002] An adjustable bolt assembly refers to a design that allows the user to adjust its length or other specific parameters so that it can flexibly adapt to different needs and conditions during installation and use.

[0003] The existing patent (publication (announcement) number: CN220706200U) discloses an adjustable bolt assembly, which can extend outward or retract inward inside the first stud by twisting the second stud, thereby completing the adjustment of the bolt length.

[0004] However, after the length adjustment is completed, the above-mentioned device needs to use the screw holes arranged at intervals on the second stud, and use the fixing screws to screw into the screw holes to limit and fix the second stud. Since the screw holes are arranged at intervals on the second stud, and the fixing screws and the screw holes must be aligned before they can be fixed, the length cannot be adjusted arbitrarily, and the length can only be limited after the fixing screws and the screw holes are aligned, thus reducing the applicability of the device.

[0005] To this end, we propose an adjustable bolt assembly to solve the above problems. Utility Model Content

[0008] Preferably, a rotation groove is provided at the top of the interior of the connecting column, and the knob is arranged inside the rotation groove.

[0009] Preferably, an adjusting groove is provided at the bottom of the connecting column, and the adjusting screw and the lifting screw are both arranged inside the adjusting groove.

[0010] Preferably, two ends of the top of the lifting screw are provided with limiting grooves, and the limiting columns are arranged inside the limiting grooves.

[0011] Preferably, a threaded hole is opened at the center of the top of the lifting screw, and the adjusting screw is arranged inside the threaded hole and adapted thereto.

[0012] Preferably, an elastic gasket is fixedly connected to the bottom of the connecting column, and a plurality of anti-slip grooves are formed at both ends of the bottom of the elastic gasket.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model drives the rotating shaft and the adjusting screw to rotate by rotating the knob inside the rotating groove. The adjusting screw drives the lifting screw to lift and lower along the limiting column inside the limiting groove with the help of the threaded hole. Utilizing the above structure, the length of the lifting screw is adjusted without position restriction, thereby achieving the effect of improving the applicability of the device.
