Embodiment Construction

[0031] The following is attached Figure 2 to 6 To further illustrate the specific implementation of a detachable expansion bolt sleeve of the present invention. The detachable expansion bolt sleeve of the present invention is not limited to the description of the following embodiments.

[0032] Such as figure 2 As shown, a detachable expansion bolt sleeve includes a sleeve section 23 and an expansion section 25. The outer end of the sleeve 2 is provided with an extension section 21 extending outward along the direction of the busbar of the sleeve 2, and the end of the extension section 21 extending outward is provided with a clamping point 22. The clamping point 22 and the extension section 21, the sleeve section 23 and the expansion section 25 of the sleeve 2 are integrally stamped and formed, or integrally cut and formed. Such as image 3 As shown, it is a schematic diagram of the overall structure of an expansion bolt formed by assembling the sleeve 2 of the present invent...

Abstract

The invention provides a detachable expansion bolt sleeve. The detachable expansion bolt sleeve comprises a sleeve section and an expansion section, wherein an extending section which extends outwardsin the direction of the sleeve bus is arranged at the outer end of the sleeve. During mounting, the expansion bolt sleeve is inserted into a mounting hole until the required depth is reached, and theextending section of the sleeve is bent outwards by 90 degrees by hand or by means of a tool, so that a second bending section is attached to a mounting wall body or the ground, the depth and the rotation of the sleeve can be controlled and limited in the follow-up screwing process of a nut of the expansion bolt. During dismounting, the nut is screwed down and the bolt is knocked, and then the second bending section is raised up or pried, so that a clamping point at the tail end of the extending section is conveniently and stably clamped through a vice or sharp-nose pliers, and the sleeve ispulled out from the mounting hole. According to the detachable expansion bolt sleeve, the existing sleeve production process is not changed, the production process is not increased, and the detachableexpansion bolt sleeve can be produced only by changing the cutting size or a stamping die of the sleeve in the existing production process, so that the cost can not be additionally increased comparedwith an existing product.

Description

Technical field [0001] The invention belongs to the technical field of mechanical engineering, and relates to an expansion bolt used for anchoring or fixing, in particular to a detachable expansion bolt sleeve. Background technique [0002] The casing is an important part of the expansion bolt. The expansion bolt composed of the casing and bolts is suitable for anchoring on concrete or brick walls and foundations. It has the characteristics of easy use, reliable connection and low price. . Such as figure 1 As shown, it is the most widely used and cheapest metal expansion bolt, including bolt 1, sleeve 2, flat washer 3, spring washer 4 and nut 5. The sleeve 2 is an integrated cylindrical structure, The inner end of the wall is provided with more than two expansion joints 24, which divide the casing 2 into a sleeve section 23 and an expansion section 25. For the expansion bolts that have been installed, the key to removing them is to remove the casing first. However, since the c...
