Abstract
Description
Technical Field
[0001] The utility model relates to a construction electric drill, in particular to an electric drill mechanism for drilling rebar planting holes on a roof floor slab that can accurately control the depth. Background Art
[0002] Roof-type photovoltaic power generation is a way of using the existing roof surface to arrange photovoltaic modules for power generation. These photovoltaic modules are later arranged on the floor structure layer of the old roof. Due to the uneven thickness of the concrete floor slab in the old roof, when installing the photovoltaic power generation bracket, it is necessary to drill rebar planting holes on the floor slab of the building roof. After planting the rebars, they are used to fix the photovoltaic panel bracket. During the on-site drilling operation, it is only judged by the experience of the workers, resulting in the inability to control the depth of the drilled rebar planting holes. The phenomenon of drilling through the floor slab often occurs, affecting the waterproof function of the floor slab of the building roof. How to accurately control the drilling depth of the rebar planting holes is a problem that needs to be solved on site. Summary of the Invention
[0003] The utility model provides an electric drill mechanism for drilling rebar planting holes on a roof floor slab that can accurately control the drilling depth, and solves the technical problem that the depth cannot be accurately controlled when drilling rebar planting holes in the prior art.
[0004] The utility model solves the above technical problems through the following technical solutions:
[0005] An electric drill mechanism for drilling rebar planting holes on a roof floor slab that can accurately control the drilling depth includes a hand-held electric drill. A front handle and a drill bit are respectively arranged on the hand-held electric drill. A horizontal sleeve is welded and connected to the side vertical surface of the hand-held electric drill above the front handle. The central axis of the horizontal sleeve is parallel to the central axis of the drill bit. A limiting rod is movably inserted into the horizontal sleeve. The front part of the limiting rod is arranged outside the drill bit. A jackscrew embedding groove is spacedly arranged in the middle of the limiting rod. A jackscrew threaded hole is arranged on the horizontal sleeve. A jackscrew is screwed into the jackscrew threaded hole, and the jackscrew abuts against the jackscrew embedding groove in the middle of the limiting rod.
[0006] The drill bit on the hand-held electric drill vertically abuts against the top surface of the roof floor slab; when the hole drilled by the drill bit on the roof floor slab reaches the designed depth, the front end of the limiting rod abuts against the top surface of the roof floor slab.
[0007] By installing a limiting rod on the hand-held electric drill, when drilling rebar planting holes on the roof floor slab, the drilling depth can be effectively controlled, and the phenomenon of drilling through the floor slab is avoided; the movable cooperation and adjustment between the limiting rod and the horizontal sleeve can meet the requirements of drilling holes with various depths, and the operation is simple, and the installation, adjustment and disassembly are all convenient.

[0014] The present utility model will be described in detail below with reference to the accompanying drawings:
[0015] A drilling mechanism for drilling a rebar planting hole on a roof floor slab that can accurately control the drilling depth includes a hand-held electric drill 1. A front handle 2 and a drill bit 3 are respectively arranged on the hand-held electric drill 1. A horizontal sleeve 4 is welded and connected to the side vertical surface of the hand-held electric drill 1 above the front handle 2. The central axis of the horizontal sleeve 4 and the central axis of the drill bit 3 are arranged parallel to each other. A limiting rod 5 is movably inserted into the horizontal sleeve 4. The front part of the limiting rod 5 is arranged outside the drill bit 3. A jackscrew embedding groove 8 is spacedly arranged in the middle of the limiting rod 5. A jackscrew threaded hole 6 is arranged on the horizontal sleeve 4. A jackscrew 7 is screwed into the jackscrew threaded hole 6. The jackscrew 7 abuts against the jackscrew embedding groove 8 in the middle of the limiting rod 5; the distance between the top end of the drill bit 3 and the top end of the limiting rod 5 is the drilling depth; when the drilling depth needs to be adjusted, only the position of the limiting rod 5 needs to be moved, and then the limiting rod with the adjusted position is fixed by the jackscrew 7.
[0016] The drill bit 3 on the hand-held electric drill 1 vertically abuts against the top surface of the roof floor slab 9; when the hole drilled by the drill bit 3 on the roof floor slab 9 reaches the designed depth, the front end of the limiting rod 5 abuts against the top surface of the roof floor slab 9.
