[0001] The utility model relates to the technical field of protective structures, in particular to a protective structure for an electric drill. Background Art

[0002] The electric drill is an electric tool used to drill or expand holes in various objects. When drilling holes in different objects, the electric drill will produce various debris. In order to prevent the debris from splashing randomly, a protective structure is set on the electric drill to prevent the debris from splashing randomly when the electric drill is in use.

[0003] For example, the utility model patent with Chinese patent number CN219852254U discloses a protective device for an electric drill, which includes a clamping piece with mounting seats on both sides, the clamping piece is used to clamp one end of the electric drill to install the drill bit; there are two telescopic pieces, the two telescopic pieces are respectively passed through the corresponding mounting seats, and the two telescopic pieces are parallel to the axis of the drill bit; a protective cover is provided with a channel for the drill bit of the electric drill to pass through, and the protective cover is arranged at one end of the two telescopic pieces away from the mounting seats; by setting the protective cover, the protective cover covers the drilling part of the object to be drilled during drilling, and can completely block all kinds of flying sparks and waste chips generated during the drilling process in the protective cover, so as to avoid the sparks and waste chips from polluting the construction environment and splashing onto the face or eyes of the operator, causing certain injuries to the operator, and the telescopic piece ensures the stability of the protective cover during the working process, and avoids the problem that the protective cover affects the use of the electric drill when protecting the drilling part.

[0004] Although the above device can effectively prevent debris from splashing randomly, it cannot effectively collect the debris after each drilling is completed, causing the debris to be scattered on the ground or on the surface of objects, requiring subsequent cleaning by staff, and the debris is likely to enter the drill hole, increasing the labor burden of the staff. Utility Model Content

[0005] The utility model discloses a protective structure for an electric drill, which solves the problem that after the electric drill drills a hole in an object, the debris cannot be collected, resulting in the debris being scattered on the surface of the object on the ground, and workers need to clean it up.

[0006] In order to solve the above technical problems, the utility model specifically adopts the following technical solutions:

[0007] A protective structure for an electric drill comprises a protective cover, one side of the protective cover is connected to a funnel-shaped connecting cover, a connecting plate is fixed inside the protective cover, a connecting rod for sliding connection passes through the connecting plate, a connecting ring is fixed to the end of the connecting rod away from the connecting cover; the outer ring surface of the connecting ring contacts the inner wall of the protective cover, a side of the connecting ring away from the connecting rod is flush with a side of the protective cover away from the connecting cover, a limiting block is fixed on the connecting rod and contacts with a side of the connecting plate close to the connecting ring; a rotatable disc is provided on the protective cover, and an adhesive layer is pasted on the disc and is flush with the side of the connecting ring away from the connecting cover.

[0008] Compared with the prior art, the utility model has the following beneficial effects:

[0009] After the protective cover is installed on the electric drill, the drill bit of the electric drill passes through the connecting cover and enters the protective cover. When the electric drill is used to drill a hole in an object, the protective cover and the connecting ring fit against the object to cover the part of the object that needs to be drilled. When the protective cover is used in a horizontal state, the drill bit passes through the inner side of the connecting ring to drill a hole in the object. During the process, the debris generated when the object is drilled enters the protective cover through the inner side of the connecting ring. The connecting ring can block the debris in the protective cover. When the object is drilled, the staff can pull the connecting ring outside the protective cover and pour the debris in the protective cover into the external collection device. When the protective cover is used in an upward state away from the connecting cover, the debris generated by the object when the drill bit is drilling a hole can also enter the protective cover and be collected. The above operation is used to pour the debris out of the protective cover; when the protective cover is used in a downward state with one side away from the connecting cover, the disc is first rotated 180 degrees to avoid the adhesive layer from contacting the object; when the object is drilled, the protective cover is moved away from the object, and then the disc is rotated to reset the disc, and then the adhesive layer is used to stick the debris on the surface of the object, and the adhesive layer can be replaced later; regardless of whether the electric drill is used in a horizontal state or an upward state, the utility model can effectively collect the debris generated by drilling the object to avoid the debris from being scattered on the ground or the surface of the object; when the electric drill is used in a downward state, after the object is drilled, the staff can also quickly collect the debris, and the debris will not enter the drill hole, thereby reducing the labor burden of the staff.

[0012] The specific contents of the utility model are described in detail below with reference to the accompanying drawings and embodiments.

[0013] like Figure 1 As shown, the utility model provides a protective structure for an electric drill, comprising a protective cover 1, one side of the protective cover 1 is connected to a funnel-shaped connecting cover 2, a connecting plate 3 is fixed inside the protective cover 1, a connecting rod 31 slidably connected is passed through the connecting plate 3, a connecting ring 32 is fixed to the end of the connecting rod 31 away from the connecting cover 2; the outer ring surface of the connecting ring 32 contacts the inner wall of the protective cover 1, a side of the connecting ring 32 away from the connecting rod 31 is flush with the side of the protective cover 1 away from the connecting cover 2, a limit block 33 is fixed on the connecting rod 31 and contacts with a side of the connecting plate 3 close to the connecting ring 32; a rotatable disk 41 is provided on the protective cover 1, and an adhesive layer 42 is pasted on the disk 41 and is flush with the side of the connecting ring 32 away from the connecting cover 2.

[0014] like Figure 1 As shown, a funnel-shaped fixed cover 7 is fixed in the connecting cover 2, and the end of the fixed cover 7 with a smaller diameter extends into the protective cover 1; the end of the connecting cover 2 with a larger diameter is connected to the protective cover 1, and the inner diameter of the side of the connecting cover 2 away from the protective cover 1 is the same as the inner diameter of the side of the fixed cover 7 located in the protective cover 1. When the drill bit used is of a smaller diameter, there is a larger gap between the drill bit and the inner wall of the connecting cover 2, and the protective cover 1 is used in an upward state, the debris entering the protective cover 1 after drilling the object can be blocked by the outer wall of the fixed cover 7, so that the debris is prevented from all gathering toward the side of the connecting cover 2 away from the protective cover 1, and the debris is prevented from falling downward from the gap between the drill bit and the inner wall of the connecting cover 2.

[0015] like Figure 1 As shown, a connecting tube 6 is fixed on the outer wall of the protective cover 1, and a plug rod 4 is inserted into the connecting tube 6. A screw rod 61 connected by a thread runs through the connecting tube 6, and a screw hole adapted to the screw rod 61 is provided on the plug rod 4; the top of the plug rod 4 is rotatably connected with the bottom of the disc 41. After the plug rod 4 is inserted into the connecting tube 6, the plug rod 4 and the connecting tube 6 are fixed by the screw rod 61, and the disc 41 can be rotated as needed later; and the connection between the disc 41 and the plug rod 4 has a certain friction force, and a force needs to be applied to assist the rotation to prevent the disc 41 from rotating at will.

[0016] like Figure 1As shown, there are two adhesive layers 42, which are respectively located on both sides of the disc 41, and a turning handle 5 is fixed on the top of the disc 41. The adhesive layers 42 are made of dot double-sided adhesive tape. After the adhesive layers 42 are respectively attached to both sides of the disc 41, the paper on one side of the adhesive layer 42 facing away from the disc 41 can be torn off. When the drill bit processes the object, the other adhesive layer 42 on the disc 41 that has not been torn off the remaining paper is made to fit the object; when the object is processed, the protective cover 1 can be moved away from the object, and the disc 41 can be rotated by the turning handle 5, and then the adhesive surface of the adhesive layer 42 after the paper is previously torn off can be made to contact with the debris on the surface of the object to stick the debris. The two adhesive layers 42 can be used alternately; the above-mentioned operation of sticking the debris is generally used when the drill bit is facing downward, that is, when the protective cover 1 is facing downward, and when drilling downward from the top surface of the object.

[0017] like Figure 1 As shown, a fixing block 34 is fixed to one end of the connecting rod 31 away from the connecting ring 32. The setting of the fixing block 34 can prevent the connecting rod 31 from being separated from the connecting plate 3.

[0018] like Figure 1 As shown, the limit block 33 is made of magnet, and the connecting plate 3 is made of steel. The limit block 33 can be adsorbed on the connecting plate 3 to prevent the connecting ring 32 from moving at will.

[0019] When in use, the protective cover 1 in the present application is installed on the electric drill in the same way as the protective cover in the patent document proposed in the background technology, and is also made of transparent rubber, which will not be described in detail here; after the protective cover 1 is installed on the electric drill, the drill bit passes through the connecting cover 2 and enters the protective cover 1. When the drill bit drills a hole on the vertical surface of an object, the protective cover 1 is in a horizontal state, covering the drilling part of the object, and the connecting ring 32 fits against the surface of the object. When the drill bit drills the object and the drill bit continues to penetrate into the object, the debris generated when the object is drilled enters the protective cover 1 through the inner side of the connecting ring 32. When the object is drilled, the drill bit and the protective cover 1 are separated from the object, and the connecting ring 32 can block the debris in the protective cover 1 to prevent the debris from scattering from the protective cover 1 to the ground. Subsequent staff pulls the connecting ring 32 to make the connecting rod 31 slide, so that the connecting ring 32 After moving outside the protective cover 1, the debris can be poured into an external collection device; when the drill bit drills a hole upward on the bottom surface of the object, the side of the protective cover 1 away from the connecting cover 2 is in an upward state, and the debris generated after the object is drilled enters the protective cover 1. When the drilling is completed, the staff moves the connecting ring 32 according to the above operation to pour the debris into the external collection device; when the drill bit drills a hole downward on the top surface of the object, the side of the protective cover 1 away from the connecting cover 2 is in a downward state. At this time, the disc 41 is rotated so that the adhesive layer 42 on the disc 41 does not contact the surface of the object. When the drilling of the object is completed, the protective cover 1 is separated from the object, and the disc 41 is rotated to make the adhesive surface of the adhesive layer 42 contact with the debris on the surface of the object, so as to stick the debris and clean the debris on the surface of the object. Later, when there is a lot of debris on the adhesive surface of the adhesive layer 42, the adhesive layer 42 can be replaced.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
