Technical Field

The invention relates to the technical field of bolt connection, in particular to a unidirectional assembling fastening bolt for fastening and connecting thin plates.

Background

In the installation of panel beating or sheet metal, need realize two fastenings by the connector with the bolt and nut cooperation, when carrying out fastening operation, generally need fixing bolt (nut), reuse spanner screw up nut (bolt), but under the connector has one side by the confined condition, because the bolt head external diameter is greater than the threaded rod external diameter, the bolt can't be packed into, even the bolt of having packed into, also can't reach fixing bolt or nut's purpose easily, bolt and nut can rotate simultaneously when screwing up this moment, can't reach the effect of fastening, just need the bolt that can put into and screw up under the semi-closed condition at this moment to go to solve this problem.

In the installation of such semi-closed condition, generally, a nut is welded or a mounting hole is punched into a threaded hole in the closed space, the welding method needs to increase labor and cost, and the threaded hole cannot be directly punched when the connected piece is thin. Therefore, in view of the situation, the invention provides a unidirectional assembly fastening bolt for fastening and connecting thin plates, which is used for installation under the condition that nuts are not welded and the connected parts are thin plates, so as to solve the bolt connection problem under the semi-closed condition.

Disclosure of Invention

Technical problem to be solved

Aiming at the defects of the prior art, the invention provides the unidirectional assembling fastening bolt for fastening and connecting thin plates, and solves the problem of difficult bolt connection under the semi-closed condition.

(II) technical scheme

In order to achieve the purpose, the invention is realized by the following technical scheme: a unidirectional assembling fastening bolt for fastening and connecting thin plates comprises a bolt and a clamp.

Preferably, the bolt includes the nut, the top of nut is provided with the boss, the last fixed surface of boss is connected with the screw rod, first through-hole has been seted up to the surface of screw rod, the surface of screw rod just is close to the top and has seted up the second through-hole, the surface threaded connection of screw rod has the nut, be provided with the gasket between nut and the nut.

Preferably, the outer surface of anchor clamps is provided with the shrink ring, the inside fixedly connected with anticreep horizontal pole of shrink ring, the end is buckled to the one end fixedly connected with that anchor clamps are close to the bolt.

Preferably, the bolt is M5, the height of nut and boss is 2.5mm, the diameter of nut is 10mm, the height of boss is 1mm, the boss is 5mm to the marginal minimum distance of first through-hole, the diameter of first through-hole and second through-hole is 2.5mm, the marginal minimum distance of first through-hole and second through-hole is 3mm, the minimum height of screw rod is 16mm, the height of anchor clamps is 50mm, the length of buckling the end is 2mm, the width of buckling the end is 1.5mm, the thickness of buckling the end is 1.5mm, the diameter of nut is 12 mm.

The working principle is as follows: insert in first through-hole 1.4 bending end 2.2 first, promote to tighten up ring 2.1 and make anchor clamps 2 tighten up, put nut 1.1 into the mounting hole enclosure space again, keep screw rod 1.2 vertical upwards, then in proper order from screw rod 1.2 afterbody cluster into gasket 3, nut 4, screw nut 4 with the hand to second through-hole 1.5 expose, loosen anchor clamps 2, insert bending end 2.2 into second through-hole 1.5, promote to tighten up ring 2.1 and make anchor clamps 2 tighten up, tighten up nut 4 with the spanner at last, loosen anchor clamps 2, accomplish the installation, when the coupling member is thicker, can't put nut 1.1 into the mounting hole when bending end 2.2 on anchor clamps 2 inserts through-hole 1.4, can insert bending end 2.2 on anchor clamps 2 into second through-hole 1.5 and then put nut 1.1, then loosen anchor clamps 2, insert bending end 2.2 on anchor clamps 2 into first through-hole 1.4 again, cluster into gasket 3 and nut 4.

(III) advantageous effects

The invention provides a unidirectional assembling fastening bolt for fastening and connecting thin plates. The method has the following beneficial effects:

1. simple structure, convenient to use can accomplish the bolt-up under the semi-closed condition through simple operation, has solved under the semi-closed condition that the bolt can't be packed into and bolt one end can't be fixed and lead to the problem that bolt nut rotated simultaneously.

2. The tightening ring of design can make anchor clamps operate convenience more when using, and wherein the anticreep horizontal pole can prevent droing of tightening ring, uses more reliably.
