An electric drill with a positioning structure

Abstract

This utility model relates to the field of electric drill technology and discloses an electric drill with a positioning structure, including: an electric drill body, the outer wall of which has a sliding groove, the sliding grooves being symmetrically arranged, and the inner wall of which has an adapter groove, the adapter grooves being symmetrically arranged. By driving the connecting rod two to slide, the connecting rod one drives the eccentric disc to rotate around the axis, thereby causing the eccentric disc to rotate around the axis and press against the sliding plate, causing the sliding plate to slide along the trajectory of the sliding groove and contact one side of the sliding block. When the locking pin and the locking groove are on the same horizontal plane, the braking torque, under the action of the spring one, drives the locking pin to slide and engage with the locking groove, thereby fixing the position of the sliding plate. Because the sliding block slides along the trajectory of the guide pin, the sliding of the sliding block is slowed down by the action of the friction pad, thus achieving the purpose of slowly advancing the electric drill body when drilling.

Description

Technical Field

[0001] This utility model relates to the field of electric drill technology, specifically an electric drill with a positioning structure. Background Technology

[0002] Electric drills are widely used in many fields such as construction, decoration, and furniture manufacturing. For example, in the process of home renovation, electric drills are often needed to penetrate walls, drill holes, and install equipment. In addition, in the medical field, electric drills are also used in delicate surgeries such as dentistry and otology.

[0003] When drilling into a wall with an electric drill, the operator may cause the drill bit to deviate from the intended direction due to slight hand tremors. This not only means that the drill bit needs to be repositioned and drilled again, but may also leave unnecessary holes in the wall due to multiple attempts. In addition, some electric drills equipped with positioning mechanisms on the market are often difficult to adjust flexibly to meet the slow and precise forward movement requirements in actual operation, and cannot perfectly match the drilling stroke of the electric drill. Utility Model Content

[0004] The purpose of this invention is to provide an electric drill with a positioning structure to achieve the above-mentioned objective.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electric drill with a positioning structure, comprising: an electric drill body, wherein a sliding groove is formed on the outer wall of the electric drill body, the sliding grooves are symmetrically arranged, an adapter groove is formed on the inner wall of the sliding groove, the adapter grooves are symmetrically arranged, a locking groove is formed on the outer wall of the electric drill body, the locking grooves are symmetrically arranged, and the locking grooves are connected to the adapter grooves; a sliding part is provided on the outer wall of the electric drill body; and a blocking part is provided on the outer wall of the electric drill body.

[0006] Preferably, the sliding part includes: a guide post, fixedly connected to the inner wall of the first slide groove; a sliding plate, slidably connected between the inner walls of the first slide groove, the sliding plates being symmetrically arranged; and an eccentric disc, rotatably connected between the inner walls of the adapter groove, the eccentric disc being symmetrically arranged. By rotating the eccentric disc around the axis and sliding the sliding plate along the trajectory of the first slide groove, precise control of the drilling body's propulsion speed can be achieved.

[0007] Preferably, a sliding block is slidably connected to the outer wall of the guide post. The sliding block is adapted to a sliding plate. An installation groove is provided on one side of the sliding plate. A friction pad is fixedly connected inside the installation groove. The friction pad is adapted to the sliding block.

[0009] Preferably, a braking torque is fixedly connected to one end of the locking pin, and a connecting groove is provided on one side of the braking torque. The connecting grooves are symmetrically arranged, and a spring is provided between the connecting groove and the connecting rod 2. One end of the spring is fixedly connected to the inner wall of the connecting groove, and the other end of the spring is fixedly connected to one side of the connecting rod 2.

[0010] Preferably, the blocking part includes: a fixing rod, which is fixedly connected to one side of the sliding block; and an arc-shaped magnetic stone, which is sleeved on the outer wall of the electric drill body, and the arc-shaped magnetic stones are symmetrically arranged.

[0013] This utility model provides an electric drill with a positioning structure. It has the following beneficial effects:

[0014] (1) This utility model drives the connecting rod 2 to slide, thereby driving the eccentric disk to rotate around the shaft under the transmission of the connecting rod 1. This causes the eccentric disk to rotate around the shaft and squeeze the sliding plate, so that the sliding plate slides along the trajectory of the sliding groove 1 and contacts one side of the sliding block. When the locking pin and the locking groove are on the same horizontal plane, the braking torque drives the locking pin to slide under the action of the spring 1 and engages with the locking groove, thereby achieving the purpose of fixing the position of the sliding plate. Since the sliding block slides along the trajectory of the guide pin, the sliding block slides slowly under the action of the friction pad, thereby achieving the purpose of slowly advancing the electric drill body when drilling.

[0015] (2) When one side of the connecting frame is pressed against the surface to be drilled, the wall surface and the drill bit of the electric drill body are sealed under the action of the arc-shaped magnetic stone and the elastic baffle. Under the action of the anti-slip plate, the connecting frame is not easy to shake or tilt. Under the action of the electric drill body, the surface to be drilled is drilled. Under the action of the diversion plate, the dust flows into the inside of the collection box, so as to achieve the purpose of timely dust collection. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example 1

[0026] A preferred embodiment of the electric drill with a positioning structure provided by this utility model is, for example... Figure 1-5 As shown: An electric drill with a positioning structure includes: an electric drill body 1, a sliding groove 1 is formed on the outer wall of the electric drill body 1, the sliding groove 1 is symmetrically arranged, an adapter groove is formed on the inner wall of the sliding groove 1, the adapter groove is symmetrically arranged, a locking groove is formed on the outer wall of the electric drill body 1, the locking groove is symmetrically arranged, and the locking groove is connected to the adapter groove; a sliding part 2 is provided on the outer wall of the electric drill body 1; and a blocking part 3 is provided on the outer wall of the electric drill body 1.

[0027] The sliding part 2 includes: a guide post 211, which is fixedly connected to the inner wall of the first slide groove; a sliding plate 213, which is slidably connected between the inner walls of the first slide groove, and the sliding plates 213 are symmetrically arranged; and an eccentric disk 215, which is rotatably connected between the inner walls of the adapter groove, and the eccentric disk 215 is symmetrically arranged.

[0028] The outer wall of the guide post 211 is slidably connected to a sliding block 212, which is adapted to a sliding plate 213. A mounting groove is provided on one side of the sliding plate 213, and a friction pad 214 is fixedly connected inside the mounting groove. The friction pad 214 is adapted to the sliding block 212.

[0029] The eccentric disk 215 is adapted to the sliding plate 213. A shaft is fixedly connected to one side of the eccentric disk 215. One end of the shaft extends outward through the adaptation groove. A connecting rod 216 is fixedly connected to one end of the shaft. A connecting rod 217 is rotatably connected to one end of the connecting rod 216. A locking pin 218 is slidably connected inside the connecting rod 217. The locking pin 218 engages with the locking groove.

[0030] One end of the locking pin 218 is fixedly connected to a braking torque 219. A connecting groove is provided on one side of the braking torque 219. The connecting grooves are symmetrically arranged. A spring 220 is provided between the connecting groove and the connecting rod 217. One end of the spring 220 is fixedly connected to the inner wall of the connecting groove, and the other end of the spring 220 is fixedly connected to one side of the connecting rod 217.

[0031] Furthermore, in this embodiment, by driving the connecting rod 217 to slide, the eccentric disk 215 is driven to rotate around the axis under the transmission of the connecting rod 216. This causes the eccentric disk 215 to rotate around the axis and press against the sliding plate 213, causing the sliding plate 213 to slide along the track of the first groove and contact one side of the sliding block 212. When the locking pin 218 and the locking groove are on the same horizontal plane, the braking torque 219 drives the locking pin 218 to slide under the action of the spring 220 and engage with the locking groove, thereby achieving the purpose of fixing the position of the sliding plate 213. Since the sliding block 212 slides along the track of the guide post 211, the sliding of the sliding block 212 is slowed down under the action of the friction pad 214, thereby achieving the purpose of slowly advancing the electric drill body 1 when drilling. Example 2

[0032] Based on Embodiment 1, a preferred embodiment of the electric drill with a positioning structure provided by this utility model is, for example... Figure 1-5 As shown: The shielding part 3 includes: a fixed rod 311, which is fixedly connected to one side of the sliding block 212; and an arc-shaped magnetic stone 313, which is sleeved on the outer wall of the electric drill body 1, and the arc-shaped magnetic stones 313 are symmetrically arranged.

[0033] One end of the fixed rod 311 is fixedly connected to the connecting frame 312. An elastic baffle 314 is provided between the connecting frame 312 and the arc-shaped magnetic stone 313. One end of the elastic baffle 314 is fixedly connected to one side of the connecting frame 312, and the other end of the elastic baffle 314 is fixedly connected to one side of the arc-shaped magnetic stone 313.

[0034] A placement slot is provided on one side of the connecting frame 312. An anti-slip plate 315 is fixedly connected to the inner wall of the placement slot. A collection box 317 is fixedly connected between the inner sides of the connecting frame 312. A diversion plate 316 is fixedly connected to the inner wall of the connecting frame 312. The diversion plates 316 are symmetrically arranged and are adapted to the collection box 317.

[0035] Furthermore, in this embodiment, when one side of the connecting frame 312 is pressed against the surface to be drilled, the arc-shaped magnetic stone 313 and the elastic baffle 314 create a closed state between the wall and the drill bit of the electric drill body 1. Under the action of the anti-slip plate 315, the connecting frame 312 is not easy to shake or tilt. Thus, the electric drill body 1 drills a hole in the surface to be drilled. Under the action of the diversion plate 316, the dust flows into the inside of the collection box 317, achieving the purpose of timely dust collection.

[0036] In use, firstly, the drive connecting rod 217 slides, thereby driving the eccentric disk 215 to rotate around the axis under the transmission of the connecting rod 216. This rotation of the eccentric disk 215 compresses the sliding plate 213, causing it to slide along the track of the first sliding groove and contact one side of the sliding block 212. When the locking pin 218 and the locking groove are on the same horizontal plane, the braking torque 219, under the action of the spring 220, drives the locking pin 218 to slide and engage with the locking groove, thus fixing the position of the sliding plate 213. Since the sliding block 212 slides along the track of the guide post 211... Thus, under the action of the friction pad 214, the sliding block 212 slides slowly, thereby achieving the purpose of slowly advancing forward when the electric drill body 1 drills; secondly, when one side of the connecting frame 312 is pressed against the surface to be drilled, under the action of the arc-shaped magnetic stone 313 and the elastic baffle 314, the wall surface and the drill bit of the electric drill body 1 are in a closed state. Under the action of the anti-slip plate 315, the connecting frame 312 is not easy to shake or tilt, thereby drilling the surface to be drilled under the action of the electric drill body 1. Under the action of the diversion plate 316, the dust flows into the inside of the collection box 317, achieving the purpose of timely dust collection.
