Problems solved by technology

Since bolts and nuts are used in pairs, during the process of tightening the nuts, the nuts often slip off from the bolts. When the nuts fall off and look for the nuts, it is troublesome to find them.
Especially in the furniture installation site, the environment is relatively messy, and the bolts and nuts are placed randomly. During the installation process, it takes many attempts to find the nuts that match the bolts, which affects the installation efficiency.

Embodiment Construction

[0013] The present invention will be described in further detail below by means of specific embodiments:

[0014] The reference signs in the accompanying drawings of the description include: bolt head 10, groove 11, rubber expansion sleeve 12, permanent magnet 13, ejection channel 14, rubber plug 15, threaded rod 20, and tool relief groove 21.

[0015] The embodiment is basically as attached figure 1 As shown: a magnetic bolt, including a bolt head 10 and a threaded rod 20 formed integrally with it, and the joint between the bolt head 10 and the bolt rod adopts a circular arc transition. A groove 11 is provided in the middle of the bolt head 10, and the cross-sectional shape of the groove 11 is a regular hexagon. A rubber expansion sleeve 12 is embedded in the groove 11, and a permanent magnet 13 is installed in the rubber expansion sleeve 12. The end surface of the permanent magnet 13 is provided with a cross-shaped groove, and the depth of the cross-shaped groove is one-fif...

Abstract

The invention belongs to the field of furniture fasteners, in particular to a magnetic bolt. The magnetic bolt comprises a bolt head and a threaded rod, wherein the bolt head and the threaded rod are integrally formed; a groove is formed in the middle of the bolt head, an expansion sleeve is embedded in the groove, and a permanent magnet is mounted in the expansion sleeve; an ejection channel communicated with the groove is formed in the bolt head, and a rubber plug is mounted on the ejection channel; the cross section of the groove takes the shape of a regular hexagon, and a cross slot is formed in the end surface of the permanent magnet. When a nut or a gasket drops out, the magnetic bolt can quickly find the nut and the gasket.

Description

technical field [0001] The invention relates to the field of furniture fasteners, in particular to a magnetic suction bolt. Background technique [0002] Nut and bolt cooperation is one of the most common connection methods. In addition to fastening and connecting mechanical parts, it is also widely used in the field of furniture, such as the connection between wooden boards on a sofa. After the nut is screwed into the bolt, in order to prevent slipping, people usually need to use two wrenches to tighten it, that is, one wrench is stuck on the head of the bolt, and the other wrench is stuck on the nut and rotated so that the bolt and the nut are opposite. sports. Because the bolt and the nut are used in pairs, the nut often slips off from the bolt during the tightening of the nut. When the nut is dropped and the nut is looked for, it is troublesome to look for. Especially in the furniture installation site, the environment is relatively messy, and the bolts and nuts are pl...
