Description

Technical Field

[0001] The utility model relates to an electric tool, in particular to an electric drill. Background Art

[0002] An electric drill is a drilling machine that uses electricity as power. It is a conventional product among power tools and is also the most in-demand power tool product. Its annual production and sales volume accounts for one-third of the domestic power tool production. The working principle of an electric drill is: using the motor rotor of an electromagnetic rotary or electromagnetic reciprocating small-capacity motor to perform magnetic field cutting and work operation, and driving the operating device through a transmission mechanism to drive the gears to increase the power of the drill bit, so that the drill bit can scrape the surface of the object and better penetrate the object. For example, the invention patent with announcement number CN108941692A discloses a similar electric drill.

[0003] In the actual use of the above-mentioned electric drill, in order to provide users with relevant information such as product parameters and usage matters, a nameplate is usually set on the shell. However, as the nameplate is exposed to the outside world for a longer period of time, the information on the nameplate will gradually fade, wear out or even disappear, seriously affecting the reading of the information, so there is still room for improvement. Utility Model Content

[0004] The utility model aims at the shortcomings of the prior art and provides an electric drill which can realize the reading of nameplate information through a transparent cover and isolate the nameplate from the outside world, thereby preventing the nameplate information from fading, wearing and disappearing due to long-term exposure.

[0005] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0006] An electric drill comprises a shell, a mounting groove is provided on the shell, a nameplate is fitted on the bottom of the mounting groove, a transparent cover is covered on the opening of the mounting groove, and a magnetic attraction mechanism is provided between the nameplate and the bottom of the mounting groove for magnetically adsorbing the nameplate to the bottom of the mounting groove.

[0007] With the above solution, when the nameplate is fitted at the bottom of the installation slot, by covering the opening of the installation slot with a transparent cover, it is convenient to read the nameplate information and isolate the nameplate from the outside world, avoiding the problem of fading, wear and even disappearance of the nameplate information due to long-term exposure. The magnetic attraction mechanism can achieve magnetic adsorption between the nameplate and the bottom of the installation slot to prevent the nameplate from falling off when the user installs the cover, thereby improving operational efficiency and convenience.

[0008] Preferably, the magnetic attraction mechanism includes a first magnetic component and a second magnetic component. The first magnetic component is provided with at least one and is installed on one side of the nameplate close to the bottom of the mounting groove. The second magnetic component is installed at the bottom of the mounting groove and is magnetically attracted one-to-one with the first magnetic component.

[0009] By adopting the above scheme, the magnetic attraction cooperation between the first magnetic part and the second magnetic part has a simple structure and low cost, and can stably adsorb the nameplate to the bottom of the installation groove, thereby realizing the magnetic attraction function of the magnetic attraction mechanism.

[0010] Preferably, a positioning groove for accommodating the second magnetic component and the corresponding first magnetic component is opened at the bottom of the installation groove, the depth of the positioning groove is equal to the sum of the thickness of the first magnetic component and the second magnetic component, and the second magnetic component is fixed to the bottom of the positioning groove.

[0011] By adopting the above solution, the cooperation between the first magnetic member and the positioning groove can realize the pre-positioning between the nameplate and the installation groove, so that the first magnetic member on the nameplate can be accurately connected with the second magnetic member at the bottom of the installation groove, further improving the operation efficiency and convenience. At the same time, the positioning groove can provide a space for the first magnetic member and the second magnetic member, which can not only make the nameplate fit more closely with the bottom of the installation groove, but also reduce the thickness of the entire nameplate installation structure, thereby improving the aesthetics.

[0012] Preferably, a connecting column which passes through the nameplate and the cover in sequence is arranged at the bottom of the installation groove and near the corner, and an anti-dropping piece which prevents the cover from being separated from the connecting column is arranged on the end face of the connecting column.

[0013] By adopting the above solution, the connecting column can realize the pre-positioning of the cover, thereby improving the installation efficiency and convenience of the cover. The anti-dropping piece can limit the axial position relationship between the cover and the connecting column, thereby realizing the fixed connection between the cover and the installation groove.

[0014] Preferably, the cover is provided with a through hole for the connecting column to pass through, and the anti-slip member is a screw that is threadedly screwed onto the end surface of the connecting column and presses the through hole.

[0015] By adopting the above solution, the through hole is compressed by a screw, which can effectively prevent the through hole from being separated from the connecting column, thereby achieving the fixation of the cover and the installation groove.

[0016] Preferably, the end of the connecting post is flush with the side of the cover away from the nameplate.

[0017] The above solution can not only prevent the screw from being over-extruded and perforated, thus avoiding the cover from breaking, but also make the gap between the cover and the screw head disappear after the screw is tightened, thereby further improving the stability of the cover.

[0018] Preferably, the diameter of the perforation is equal to the outer diameter of the connecting column.

[0019] By adopting the above solution, the connection column and the through hole can be more closely matched, thereby preventing dust from entering the gap between the two.

[0020] Preferably, a guide arc surface is provided at the port of the perforation close to the nameplate.

[0021] By adopting the above solution, when the through hole and the connecting column are connected, the guiding arc surface can play a guiding role, so that the installation efficiency and convenience of the two are better.

[0022] Preferably, the edge of the cover is provided with a chamfered surface on a side close to the nameplate.

[0023] With the above solution, when the cover is installed, the chamfered surface can further play a guiding role, thereby improving the installation efficiency and convenience of the cover.

[0024] The utility model has a significant technical effect due to the adoption of the above technical solution: when the nameplate is fitted at the bottom of the installation slot, by covering the opening of the installation slot with a transparent cover, it is convenient to read the nameplate information and isolate the nameplate from the outside world, avoiding the problem of fading, wear and even disappearance of the nameplate information due to long-term exposure. The magnetic attraction mechanism can achieve magnetic adsorption between the nameplate and the bottom of the installation slot to prevent the nameplate from falling off when the user installs the cover, thereby improving the operating efficiency and convenience.

[0035] like Figures 1 to 5 As shown, an electric drill disclosed in this embodiment includes a shell 1, a rectangular mounting slot 2 is provided on the shell 1, a rectangular nameplate 3 is fitted on the bottom of the mounting slot 2, and the information side of the nameplate 3 is arranged outward. A transparent cover 4 is covered at the opening of the mounting slot 2, and the cover 4 is made of transparent organic glass and is arranged in a rectangular shape to adapt to the shape of the mounting slot 2. A magnetic attraction mechanism 5 for magnetically adsorbing the nameplate 3 to the bottom of the mounting slot 2 is arranged between the nameplate 3 and the bottom of the mounting slot 2. Specifically, the magnetic attraction mechanism 5 includes a first magnetic part 6 and a second magnetic part 7, and the first magnetic part 6 and the second magnetic part 7 are preferably permanent magnets. At least one first magnetic part 6 is provided and fixed to one side of the nameplate 3 close to the bottom of the mounting slot 2 by glue, and the second magnetic part 7 is installed at the bottom of the mounting slot 2 and is magnetically attracted to the first magnetic part 6 in a one-to-one correspondence.

[0036] like Figure 6 and Figure 7 As shown, in order to make the nameplate 3 fit better with the bottom of the installation groove 2, a positioning groove 8 is opened at the bottom of the installation groove 2 for accommodating the second magnetic component 7 and the corresponding first magnetic component 6. The depth of the positioning groove 8 is equal to the sum of the thicknesses of the first magnetic component 6 and the second magnetic component 7. The second magnetic component 7 is fixed to the bottom of the positioning groove 8 by glue.

[0037] As Figure 4 and Figure 6 As shown, in order to improve the installation stability of the cover 4, a connecting column 9 is sequentially provided at the bottom of the installation groove 2 and near the corner, and an anti-slip member 11 is provided on the end face of the connecting column 9 to prevent the cover 4 from being separated from the connecting column 9. Specifically, a through hole 10 for the connecting column 9 to be passed is provided on the cover 4, and the anti-slip member 11 is a screw that is screwed to the end face of the connecting column 9 and presses the through hole 10.

[0038] like Figure 6 As shown, in order to make the screw and the cover 4 fit more tightly, the end of the connecting column 9 is flush with the side of the cover 4 away from the nameplate 3.

[0039] like Figure 6 As shown, in order to make the connection column 9 and the through hole 10 fit more closely, the hole diameter of the through hole 10 is equal to the outer diameter of the connection column 9 .

[0040] like Figure 5 and Figure 8 As shown, in order to improve the installation efficiency and convenience of the cover 4, the through hole 10 is provided with a circle of guiding arc surface 12 near the end of the nameplate 3. The edge of the cover 4 is also provided with a circle of chamfered surface 13 on one side near the nameplate 3.

[0041] The specific usage process is as follows:
