Abstract

The invention discloses an expansion bolt, an expansion bolt wrench and a dismantling method of the expansion bolt. The invention discloses the expansion bolt. According to the expansion bolt, at least one strip-shaped opening is formed in the front end of an expansion pipe, two sides of the strip-shaped opening are respectively provided with at least one bayonet groove which is communicated with the strip-shaped opening, the bayonet grooves which are communicated with the strip-shaped opening can be turned back towards the front end of the expansion pipe, and the tail end of each turn-back bayonet groove is not allowed to be communicated with the strip-shaped opening or the front end of the expansion pipe. The expansion bolt has the advantages of being capable of effectively overcoming the defects that in the process of installation of the expansion bolt or after the installation of the expansion bolt is completed, when the expansion needs dismantling, the expansion bolt is not easy to dismantle.

Description

The method for dismounting of a kind of EXPANSION ANCHOR BOLTS and its EXPANSION ANCHOR BOLTS spanner and this EXPANSION ANCHOR BOLTS thereof

Technical field

The present invention relates to a kind of EXPANSION ANCHOR BOLTS.The invention still further relates to a kind of EXPANSION ANCHOR BOLTS spanner.The present invention relates to the method for dismounting of this EXPANSION ANCHOR BOLTS again.

Background technique

Traditional expansion bolt is in installation process or after installing, and when needing to remove, difficulty is very large in the operation, just can't remove fully sometimes at all, namely loses time, and is unfavorable for work safety again.

Summary of the invention

First technical problem that the present invention will solve is the dismountable function of setting up existing EXPANSION ANCHOR BOLTS; Second technical problem that the present invention will solve provides a kind of spanner of dismountable this EXPANSION ANCHOR BOLTS; The 3rd technical problem that the present invention will solve provides a kind of method for dismounting of this EXPANSION ANCHOR BOLTS.

Technological scheme of the present invention is: establish a bar shaped gap at least at the front end of expand tube, be provided with a bayonet slot that communicates with the bar shaped gap at least in the both sides of bar shaped gap.The bayonet slot that communicates with the bar shaped gap can be turned back to the front end of expand tube, and the tail end of the bayonet slot of turning back disapproves with the front end of bar shaped gap or expand tube and communicates.

The EXPANSION ANCHOR BOLTS spanner constitutes by pulling mouth, tommy bar and handle three parts, pulls mouthful front end at tommy bar, and handle is at the tail end of tommy bar.Pulling mouth is made up of open tubular column and bayonet socket key, the inner diameter of open tubular column is slightly larger than screw diameter, outer diameter is slightly less than the expand tube inside diameter, begin the degree of depth at the bottom of the open tubular column from bayonet socket key inwall place greater than the length of screw front end to bar shaped gap bottom, the bayonet socket key is fixed on the outer wall of open tubular column, and quantity, the position of the quantity of bayonet socket key, position and bayonet slot are complementary; The bayonet socket key preferably is located at the front end of open tubular column; The collar extension of open tubular column front end slightly shrinks inwards; Pull a mouthful afterbody and be provided with handle.

The method for dismounting of this EXPANSION ANCHOR BOLTS is: at first take off the nut of EXPANSION ANCHOR BOLTS and pad etc., assemble the EXPANSION ANCHOR BOLTS spanner, make the bayonet socket key will pull mouthful between the slit of inserting between expand tube and the screw rod by the bar shaped gap, rotate tommy bar by handle then, the bayonet socket key is entered in the bayonet slot, hold handle then and outwards pull at or be pulled outwardly while rotating, so just can earlier expand tube be taken out, take out screw rod at last again.

Beneficial effect of the present invention is: utilize the present invention effectively to overcome EXPANSION ANCHOR BOLTS in installation process or after installing, be difficult for the deficiency of removing when needing to remove.

Description of drawings

Below in conjunction with the drawings and specific embodiments the present invention is described in detail.

Fig. 1 is the structural representation of the embodiment of the invention 1.

Fig. 2 is embodiment 2 structural representation.

Fig. 3 is embodiment 3 structural representation.

Number in the figure:

1, expand tube 2, bar shaped gap 3, bayonet slot 4, tommy bar

5, pull mouth 6, handle 7, bayonet socket key

Embodiment

Example 1

As shown in Figure 1, establish a bar shaped gap 2 at least at the front end of expand tube 1, be provided with a bayonet slot 3 that communicates with bar shaped gap 2 in the both sides of bar shaped gap 2 at least.The bayonet slot 3 that communicates with bar shaped gap 2 can be turned back to the front end of expand tube 1, and the tail end of the bayonet slot 3 of turning back disapproves with the front end of bar shaped gap 2 or expand tube 1 and communicates.

Example 2

As shown in Figure 2, the EXPANSION ANCHOR BOLTS spanner is by pulling mouth 5, and tommy bar 4 and handle 6 three parts constitute.Pull mouthful 5 front ends at tommy bar 4, handle 6 is at the tail end of tommy bar 4; Pulling mouthfuls 5 is made up of open tubular column and bayonet socket key 7, the inner diameter of open tubular column is slightly larger than screw diameter, outer diameter is slightly less than expand tube 1 inside diameter, begin the degree of depth at the bottom of the open tubular column from bayonet socket key 7 inwall places greater than the length of screw front end to bar shaped gap 2 bottoms, bayonet socket key 7 is fixed on the outer wall of open tubular column, and quantity, the position of the quantity of bayonet socket key 7, position and bayonet slot 3 are complementary; Bayonet socket key 7 preferably is located at the front end of open tubular column; The collar extension of open tubular column front end slightly shrinks inwards; Pull mouthful 5 afterbodys and be provided with handle 6.

Example 3

As shown in Figure 3, at first take off the nut of EXPANSION ANCHOR BOLTS and pad etc., assemble the EXPANSION ANCHOR BOLTS spanner, bayonet socket key 7 will be pulled between mouthful 5 slits of inserting between expand tube 1 and the screw rod by bar shaped gap 2, rotate tommy bar 4 by handle 6 then, bayonet socket key 7 is entered in the bayonet slot 3, hold handle 6 then and outwards pull at or be pulled outwardly while rotating, so just can earlier expand tube 1 be taken out, take out screw rod at last again.
