Problems solved by technology

[0011] The above process only directly or indirectly improves the thread fit, but in practical applications, if the weight of the load-bearing plate is large, or when fastening a large-width steel plate or concrete structure, the thread fit will not work when the plate is in a suspended state or is stretched by external force. In this state, slippage and other phenomena are prone to occur, resulting in cracking or even splitting of the connection area

Embodiment 1

[0053] like Figure 1-3 As shown, this embodiment discloses a reinforced connecting bolt assembly, which includes a bolt body 1 and a nut threaded with the bolt body 1 . Also includes a fastening ring assembly, the fastening ring assembly includes a first annular ring 31, a second annular ring 32, the second annular ring 32 is concentric with the first annular ring 31 and the inner diameter of the second annular ring 32 is larger than the first annular ring 31 the outer diameter. The bolt body 1 sequentially includes a rotating rod part 11 , a first threaded rod part 12 , a clamping rod part 13 , a second threaded rod part 14 and a bottom rod part 15 along its axial direction from the front to the rear part. The nuts include a first nut 21 and a second nut 22 with the same specification, the first threaded rod part 12 cooperates with the first nut 21 , and the second threaded rod part 14 cooperates with the second nut 22 .

[0054] like figure 2 , 4 As shown, the clamping...

Embodiment 2

[0066] like Figure 1-3 As shown, the difference between the present embodiment and the above-mentioned embodiments is that each of the clamping rods 13 includes a plurality of receiving grooves 131 , and the plurality of receiving grooves 131 in the clamping rod 13 are arranged in a ring shape.

[0067] In the present invention, a plurality of receiving grooves 131 are provided, so that after all the clamping parts 132 are rotated out from the corresponding receiving grooves 131, an umbrella shape is formed, and a plurality of angular openings can cooperate with a plurality of barbs to be connected with the first annular ring 31, The second annular ring 32 is fastened to achieve the technical effects of multi-point stress and increased clamping and fastening area.

Embodiment 3

[0069] like Figure 4 As shown, the difference between this embodiment and the above-mentioned embodiments is that the hook part 1323 is hinged to the movable part 1322 through the second shaft, and the second torsion spring (not shown in the figure) is assembled so that the hook part 1323 is connected to the first movable part 1322 Acute angle openings are formed between them.

[0070] The present invention uses a torsion spring as a reset member. Of course, the elastic material in the prior art can also be directly connected to the movable part 1322 as the hook part 1323. When receiving an external force, the variable capacity of the elastic material is used to expand the opening. However, compared with elastic materials, the hook portion 1323 of the present invention can be made of a material with high modulus, high strength, and little deformation, such as a steel block, by using a torsion spring as a reset member. It is not easy to be deformed, and can further ensure the...

Abstract

The invention discloses a reinforced connecting bolt assembly, which comprises a bolt body, a nut and a fastening ring assembly, wherein the fastening ring assembly comprises a first annular ring anda second annular ring; the bolt body sequentially comprises a rotating rod part, a first threaded rod part, a clamping rod part, a second threaded rod part and a bottom rod part in the axial directionof the bolt body; the clamping rod part is provided with a storage groove, and a clamping piece is hinged in the storage groove; the connecting end of the clamping piece is hinged to the storage groove through a shaft, the free end of the clamping piece is provided with an angular opening, and the clamping piece is divided into a movable part hinged to a first shaft and a hook part elastically connected or hinged to a movable part through the angular opening; the angular opening in the free end of the clamping piece can be inserted into the first annular ring, and the hook part of the clamping piece can be hooked on the second annular ring. The invention further discloses a method for fastening a plate body by using the bolt assembly. The reinforced connecting bolt assembly has the advantages that the fastening degree between the plate bodies to be assembled can be improved, the operation is convenient, and high efficiency and rapidness can be achieved.

Description

technical field [0001] The invention relates to the technical field of fasteners, in particular to a reinforced connecting bolt assembly and a method for fastening a plate body by the bolt assembly. Background technique [0002] A bolt is a mechanical part, a cylindrical threaded fastener with a nut. At the same time, the bolt is composed of a head and a screw rod, and is used to fasten two parts with through holes. [0003] Bolts are divided according to the way they are connected: ordinary ones and those with hinged holes. According to the shape of the head: there are hexagonal head, round head, square head, countersunk head and so on. [0004] The fastening effect of the bolts in the prior art is mainly reflected in the thread fit, and the improvement of the bolts is mostly focused on strengthening the thread fit area, or improving the overall stress strength of the bolt, or improving the thread to improve the fastening stability and possible disassembly etc. [0005]...
