Problems solved by technology

[0002] Since the expansion bolt invented by British engineer John Joseph Rollins in 1911, people have used it for a whole century. It is difficult to achieve proper anchoring or secure locking with the hole wall in the porous block wall. Usually, it is repeated tossing, and finally it is used helplessly, resulting in many safety hazards
Judging from the things recorded in the existing patent literature, no better solution has been found

Embodiment Construction

[0019] Below in conjunction with accompanying drawing, the present invention and concrete implementation will be further described:

[0020] Referring to the accompanying drawings, ① a kind of expansion board (1) with slopes at both ends is designed, the expansion board (1) is provided with assembly holes (2) and (3), and the two expansion boards (1) are combined and embedded in the belt On the nut support (4) of the lug and connect it through the riveting shaft (5), the cap screw (6) is screwed on the nut support (4) with the ear, and the expansion plate is pushed by the cap screw (6) The two slopes of (1) make it open in a scissor type, and then realize the purpose of anchoring or locking; The slope limits the inward rotation of the expansion plate (1); ③ the slope at one end of the expansion plate (1) leans against the slope of the joint surface (7), and the assembly hole (2) at the other end is equipped with a return spring (8 ), the expanded expansion plate (1) is folded...

Abstract

The invention relates to a shearing type expansion bolt in the field of fastening members, which is characterized in that two expansion plate (1) with inclines at two ends are designed, assembling holes (2 and 3) are arranged on the expansion plates (1), the two expansion plates (1) are combined and embedded in a nut support (4) with lugs and connected through a riveting shaft (5), a screw (6) with caps is screwed on the nut support (4) with the lugs and pushes the two inclines of the expansion plates (1) to be spread in a shearing manner, and further the purpose of anchoring or locking is realized. The shearing type expansion bolt is continuously created and perfected on the basis of the shearing type expansion bolt with the China patent application number of 201110218903.3, meets new demands of application field, use purpose and use effect of people, and can be firmly and reliably used on a porous building block wall body and dense soil especially, thereby really realizing general value of the expansion bolt.

Description

technical field [0001] The invention relates to a scissor expansion bolt in the field of fasteners. Background technique [0002] Since the expansion bolt invented by British engineer John Joseph Rollins in 1911, people have used it for a whole century. It is difficult to achieve proper and effective anchoring or secure locking with the hole wall in the porous block wall, usually after repeated tossing, and finally use it helplessly, resulting in many potential safety hazards. Judging from the things recorded in the existing patent documents, no better solution has been found. Contents of the invention [0003] The purpose of the present invention is to design a new scissor expansion bolt for the above-mentioned status quo, which is continuously innovated and perfected on the basis of the scissor expansion bolt with the Chinese patent application number: 201110218903.3, and its scheme is more abundant, reliable and practical. [0004] Technical solution of the present in...
