Detailed Description

Example 1

As shown in fig. 1 to 4, a top plate expansion bolt wrench comprises a top plate expansion bolt, a handle 1, a bottom rod 2, a plurality of connecting rods 3 and a sleeve 4.

Because the pipeline, the corner bracket and the like need to be installed on the ceiling of the building, the pipeline and the corner bracket need to be fixed by adopting a top plate expansion bolt. The top plate expansion bolt is characterized in that a screw rod 6 is provided with a nut 7, and one end of the screw rod 6 is in threaded connection with an expansion sleeve 8. Preferably, in the embodiment, the length of the screw rod 6 is 15-25cm, and the length of the expansion sleeve 8 is 4-8 cm.

The handle 1 is connected with the bottom rod 2, and the handle 1 can be fixedly connected with the bottom rod 2 by adopting a welding or thread fixing mode.

The bottom rod 2, the connecting rods 3 and the sleeve 4 are connected in sequence. Preferably, the bottom rod 2, the plurality of connecting rods 3 and the sleeve 4 are sequentially in threaded connection. Be equipped with a plurality of connecting rods 3, can increase or shorten the length of roof expansion bolts spanner through the quantity that increases or reduces the connecting rod according to job site's actual height to satisfy actual construction demand.

The inner hole of the end part of the sleeve 4 far away from one end of the connecting rod 3 is made into an inner hexagon, and the inner wall of the end part of the sleeve 4 is provided with a base 4-1. The internal hexagonal bore at the end of the sleeve 4 corresponds to the nut 7. A plurality of sleeves 4 are arranged, and the end parts of the plurality of sleeves 4 are made into internal hexagon shapes with different specifications. According to the actual requirements of different sites, the top plate expansion bolt with the appropriate specification can be selected, and the appropriate sleeve 4 can be selected.

In order to satisfy the stability of synchronous rotation that the handle drove sill bar, connecting rod and telescopic. Preferably, in one embodiment, two reinforcing rods 5 are provided, the two reinforcing rods 5 are symmetrically installed, one end of each reinforcing rod 5 is fixedly connected with the base 2 through a bolt, and the other end of each reinforcing rod 5 is fixedly connected with two ends of the handle 1 through bolts.

The utility model discloses a working process is:

according to on-the-spot actual conditions, connect a plurality of connecting rods 3 and a sleeve 4 back in proper order, connecting rod 3 is connected with bottom bar 2, constitutes roof expansion bolts spanner. As shown in fig. 5-7, after the top plate 9 is punched, the screw rod end is directly placed into the sleeve 4 after the top plate expansion bolt is assembled, the nut of the top plate expansion bolt is just arranged in the hexagonal hole in the sleeve, the top plate expansion bolt wrench is lifted, the expansion sleeve of the top plate expansion bolt is aligned to the drilled hole of the top plate, the expansion sleeve is jacked into the drilled hole by utilizing the vertical impact force through the vertical movement of the handle, then the handle is held, the connecting rod and the sleeve are driven to rotate through rotating the handle, the screw rod is screwed into the drilled hole through a rotating mode, the expansion sleeve is expanded, and the expansion bolt is firmly installed. And after the top plate expansion bolt is installed, the top plate expansion bolt wrench is separated, and the next top plate expansion bolt is installed.
