Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dust-proof tools, and particularly relates to a dust-proof cover for an electric drill. Background Art
[0002] As a tool widely used in the fields of construction, decoration, manufacturing, etc., an electric drill can complete drilling operations on materials such as wood, metal, plastic, ceramic tile, and concrete. However, when directly using an electric drill for operation, the dust generated during drilling is likely to scatter, thus polluting the working environment and even posing a health risk to the operator. Therefore, a dust-proof cover can be added to the electric drill to simply collect the dust generated during the drilling process of the electric drill.
[0003] However, most of the existing designs of electric drill dust-proof covers adopt a single dust-receiving cover structure, and the dust generated during drilling is likely to enter the interior of the electric drill. Especially during the drilling process, the high-speed rotating drill bit will drive the surrounding air to form a vortex, making it easier for the dust to spread towards the electric drill body, which in turn leads to accelerated wear of mechanical components and an increase in the failure rate of electronic components, affecting the service life and working efficiency of the electric drill.
[0004] In addition, during the use of the existing electric drill dust-proof cover, the operator usually needs to use one hand to stabilize or hold the dust-proof cover to ensure its correct positioning at the drilling position and prevent the dust from spreading. Therefore, when drilling at a high place such as the roof through a ladder, the operator needs to hold the electric drill with one hand and hold the dust-proof cover with the other hand, thus unable to grasp the ladder while drilling, increasing the difficulty of the operation and potential safety risks. Content of the Utility Model
[0005] The purpose of the utility model is to provide a dust-proof cover for an electric drill to solve the above problems.
[0006] To solve the above technical problems, the utility model provides the following technical solution: A dust-proof cover for an electric drill, comprising a fixing part connected to the electric drill body, the fixing part is connected with a dust-receiving cover capable of accommodating dust, a partition cover capable of restricting dust from approaching the electric drill body is connected to the fixing part or the dust-receiving cover, a first through hole for the electric drill to extend out is opened on the partition cover, an elastic dust-proof pad capable of covering the first through hole is arranged on the partition cover, and a second through hole is opened on the elastic dust-proof pad.
[0007] As a further optimized solution of the utility model, the upper part of the elastic dust-proof pad has a convex part with a height gradually decreasing from the center to the periphery, and the second through hole is arranged at the center of the convex part.

[0019] 3. By connecting the cover body to the electric drill body through the fixing part, when the operator drills at high places such as the roof through a ladder, it is no longer necessary to hold the dust-proof cover by hand, ensuring the stability of the dust-proof cover during the drilling process and improving the safety of the drilling work.

[0023] The following will describe in detail the implementation mode of the present utility model with reference to the accompanying drawings.
[0024] As Figures 1 to 3 shown, the present utility model discloses a dust-proof cover for an electric drill, which includes a fixing part connected to the electric drill body, the fixing part is connected with an ash receiving cover capable of accommodating dust, and a partition cover capable of restricting dust from approaching the electric drill body is connected to the fixing part or the ash receiving cover. A first through hole for the electric drill to extend out is opened on the partition cover, and an elastic dust-proof pad capable of covering the first through hole is arranged on the partition cover, and a second through hole is opened on the elastic dust-proof pad.
[0025] The fixing part 1 can fix the entire dust-proof cover on the electric drill body. When the operator drills a hole, there is no need to hold the dust-proof cover by hand additionally, and it is ensured that the dust-proof cover will not move or fall off due to external force or vibration during the drilling process. The ash receiving cover 2 can collect and accommodate the dust generated during the drilling process through physical isolation, prevent the dust from flying around, and reduce the pollution of the working area. The shape of the ash receiving cover 2 can have various choices, such as a bucket shape or a box shape design. Preferably, the ash receiving cover 2 is a conical shape made of a transparent material, and the conical shape can facilitate the collection of dust, and the setting of the transparent material can facilitate the operator to observe the drilling situation. The partition cover 3 can limit the dust from approaching the gap between the electric drill body and the drill bit, and reduce the risk of dust entering the electric drill. The elastic dust-proof pad 4 covers the first through hole 31 of the partition cover 3, and it can be made of materials such as silica gel and rubber. Preferably, the elastic dust-proof pad 4 is detachably connected to the partition cover 3, which is convenient for maintaining the elastic dust-proof pad 4. The second through hole 41 has good elasticity, can closely fit drill bits of different diameters, and restricts the dust from escaping from the gap between the second through hole 41 and the electric drill.
[0026] Through the setting of the partition cover 3, the path of dust spreading to the electric drill body is restricted, the risk of dust entering the electric drill is reduced, thereby protecting the mechanical components and electronic components of the electric drill and prolonging the service life of the electric drill; through the elastic dust-proof pad 4 covering the first through hole and the setting of the second through hole 41 capable of elastic deformation, while allowing drill bits of different diameters to pass through, the second through hole tightly sleeves the outer periphery of the electric drill bit to restrict the dust from escaping from the gap, improving the service life and working efficiency of the electric drill; by connecting the cover body to the electric drill body through the fixing part 1, when the operator drills holes at high places such as the roof through a ladder, there is no need to hold the dust-proof cover by hand, ensuring the stability of the dust-proof cover during the drilling process and improving the safety of the drilling work.
[0027] The upper part of the elastic dust-proof pad 4 has a convex part 42 with a gradually decreasing height from the center to the periphery, and the second protruding hole 41 is arranged at the center of the convex part 42. Through the convex part 42 with a gradually decreasing height from the center to the periphery and the arrangement that the second protruding hole 41 is arranged at the center of the convex part 42, compared with the upper part of the elastic dust-proof pad 4 set as a plane, the accumulation of dust on the elastic dust-proof pad 4 can be reduced, and further, the situation that dust enters the electric drill body through the second protruding hole 41 can be avoided.
[0028] The convex part 42 is spherical-crowned. Through the arrangement that the convex part 42 is spherical-crowned, compared with shapes such as a pyramid, the accumulation of dust on the elastic dust-proof pad 4 can be further reduced, and the service life of the electric drill can be improved.
[0029] The lower part of the elastic dust-proof pad 4 abuts against the partition cover 3. Through the arrangement that the lower part of the elastic dust-proof pad 4 abuts against the partition cover 3, the situation that dust enters the elastic dust-proof pad 4 through the gap between the lower part of the elastic dust-proof pad 4 and the partition cover 3 can be reduced, and the sealing performance of the elastic dust-proof pad 4 can be further improved.
[0030] The partition cover 3 includes a partition cover main body 32 and a socket part 33 arranged on the upper part of the partition cover main body 32. Through the arrangement of the socket part 33, the elastic dust-proof pad 4 can be connected to the partition cover 3 through the socket part 33, and the connection stability between the two can be improved.
[0031] The socket part 33 is frustum-shaped with a narrower upper part and a wider lower part. Through the arrangement of the frustum-shaped socket part 33 with a narrower upper part and a wider lower part, its narrower upper part can play a guiding role when the elastic dust-proof pad 4 is inserted, enabling the operator to easily align the elastic dust-proof pad 4 with the socket part 33 and smoothly slide it in under slight pressure without excessive alignment or adjustment. As the lower part of the elastic dust-proof pad 4 is further inserted, the width of the socket part 33 gradually increases, which forces the edge of the elastic dust-proof pad 4 to expand outwards, thus generating sufficient frictional force to restrict the elastic dust-proof pad 4 from detaching, ensuring a firm connection between the elastic dust-proof pad 4 and the partition cover 3 and preventing loosening or detachment during use.
[0032] There are other implementation methods for the connection between the elastic dust-proof pad 4 and the partition cover 3. For example, by providing a clamping part on the partition cover 3 and a corresponding block on the elastic dust-proof pad 4, the fixed connection between the two can be achieved through the cooperation of the clamping part and the block; or the fixation between the two can also be completed through plugging, magnetic attraction connection and other methods.
[0033] The height of the partition cover body 32 gradually decreases from the center to the periphery, and the first protruding hole 31 is provided at the center of the partition cover body 32. By arranging the inclined surface of the partition cover body 32, the dust can be gathered in the inclined direction of the partition cover body 32. Through the arrangement that the height of the partition cover body 32 gradually decreases from the center to the periphery and the first protruding hole 31 is provided at the center of the partition cover body 32, the dust can be gathered in the direction away from the first protruding hole 31, thereby further improving the service life of the electric drill.
[0034] The fixing part 1 includes a connecting pipe 11. The upper part of the connecting pipe 11 is connected to the dust receiving cover 2, and a fixing flange 12 is provided on the inner wall of the lower part of the connecting pipe 11. The fixing flange 12 is arranged on the inner wall of the lower part of the connecting pipe 11 so as to cooperate with the electric drill body. When the operator drills a hole, there is no need to hold the dust-proof cover by hand additionally, and it is ensured that the dust-proof cover will not move or fall off due to external force or vibration during the drilling process.
[0035] There are other implementation manners of the fixing part 1. For example, a plurality of connecting rods connected to the dust receiving cover 2 are provided, and a clamping block capable of being clamped with the electric drill body is provided at one end of the connecting rod far away from the dust receiving cover 2; alternatively, a plug-in part can be arranged at one end of the connecting rod far away from the dust receiving cover 2 to realize plug-in connection with the electric drill body, or a magnetic attracting block can be arranged at one end of the connecting rod far away from the dust receiving cover 2 to realize magnetic attracting connection with the electric drill body, which is not limited herein.
[0036] After optimization, the number of the fixing flanges 12 is at least two, and the fixing flanges 12 are arranged circumferentially on the inner wall of the lower part of the connecting pipe 11. The plurality of fixing flanges 12 can provide more balanced supporting force and fixing points, avoid the skew or instability phenomenon that may be caused by single-point fixing, and ensure the stability of the dust-proof cover during the operation of the electric drill.
[0037] The fixing part 1, the dust receiving cover 2 and the partition cover 3 are integrally formed. Through the arrangement that the fixing part 1, the dust receiving cover 2 and the partition cover 3 are integrally formed, there are no additional connection points or seams between the components, reducing the risk of structural loosening or failure caused by component separation or unreliable connection, and improving the structural stability of the dust-proof cover.
[0038] The lower end of the elastic dust-proof pad 4 is tightly sleeved on the peripheral wall of the partition cover 3, and the second protruding hole 41 of the elastic dust-proof pad 4 is tightly sleeved on the outer periphery of the electric drill bit. The elastic dust-proof pad can closely fit the shape of the partition cover 3, thereby ensuring a tight seal between the two; the tight contact between the drill bit and the second protruding hole 41 can maintain a good sealing state even during vibration in the drilling process, preventing dust from escaping from the gap.
