Description

Technical Field

[0001] The invention relates to the technical field of civil engineering and mechanical engineering, and more specifically to a magnetic anti-theft bolt assembly and disassembly sleeve. Background Art

[0002] At present, infrastructure is in a period of rapid development. In particular, the corrugated guardrails on the sides of highways of all levels are being built nationwide to promote "four good highways". Anti-theft bolts are generally used to connect corrugated guardrails, and there are relatively few special wrenches. Traditional installation and removal generally use a larger electric socket or an open-end wrench, which has the disadvantage that the outer surface of the anti-theft bolt is round and has no edges and corners. The conventional socket cannot achieve the torque required by the design, and the shape of the corrugated guardrail limits the operating space of the open-end wrench, resulting in low installation efficiency. Summary of the invention

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a magnetic anti-theft bolt installation and removal sleeve.

[0004] The technical solution of the present invention is as follows: A magnetic anti-theft bolt assembly and disassembly sleeve comprises a steel pipe body, a connecting sleeve and an open sleeve, wherein a connecting sleeve is fixed to the end of the steel pipe body, and a strong magnet is fixed to the other end of the connecting sleeve; an arc-shaped groove matching the connecting sleeve is provided on the open sleeve, and the connecting sleeve is detachably embedded in the arc-shaped groove and adsorbed to the inner bottom surface of the arc-shaped groove by a strong magnet; the open sleeve is provided with an opening matching the nut; the connecting sleeve is recessed inside so that the inner diameter of the connecting sleeve is larger than the inner diameter of the open sleeve; notches are provided on the side walls of the open sleeve and the connecting sleeve for the anti-theft compression nut to enter; the open sleeve includes a variety of inner diameter models.

[0005] The internal opening of the open sleeve is hexagonal, two sides are cut off, and the diameter is adapted to the small head of the anti-theft clamping nut.

[0006] The inner diameter of the connecting sleeve is larger than the diameter of the large head of the anti-theft compression nut, and a strong magnet is adhered to the end of the connecting sleeve.

[0007] The steel pipe body and the connecting sleeve For welding, the open sleeves are held together by strong magnets at the ends of the connecting sleeves.

[0008] An auxiliary wrench hole is provided at the end of the steel pipe body, and a round stick is inserted into the auxiliary wrench hole.

[0009] The end of the steel pipe body is connected to a conventional electric sleeve drilling rig.

[0010] The open sleeve includes a variety of inner diameter models, which can be adapted to various models of anti-theft compression nuts. The open sleeves with different inner diameters are connected to the connecting sleeve by strong magnets, and are easy to replace.

[0011] Technical effects and advantages of the present invention: The anti-theft bolt installation and removal sleeve can directly utilize existing tools and can be adapted at will, thereby preventing the problem of insufficient torque due to mismatched models, improving the quality of engineering construction, and avoiding the limitation of the open-end wrench on the working space. The side insertion method simplifies the construction process, and when installing and removing conventional bolts, it can also be directly inserted from the bottom, which has a wider range of applications.

[0012] The open sleeve and the connecting sleeve are connected by magnet adsorption, which is convenient for disassembly and assembly. The open sleeves with different inner diameters can be replaced, which is convenient to replace and has a wide range of applications. BRIEF DESCRIPTION OF THE DRAWINGS
