Description

Technical Field

[0001] This utility model relates to the field of drilling technology for decoration, and in particular to a drilling device for walls. Background Technology

[0002] An existing wall drilling device, with publication number CN 207212284 U, involves gripping the handle and pushing the movable seat along a groove to drill into the wall. Upon contact with the wall, the drill and fan switches on the handle are activated. During operation, a fan in the dust collection box blows away dust generated during drilling. Under the combined effect of gravity and the fan, the dust accumulates at the funnel-shaped opening and falls into a collection bag, effectively collecting dust generated during drilling, thus being environmentally friendly and clean. However, this device is bulky and cumbersome to operate, making it difficult to clean up drilling debris, causing inconvenience for users. Utility Model Content

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] like Figures 1-4 As shown, a wall drilling device includes a handheld drill body 1, and a processing mechanism for collecting waste generated during the drilling process is provided on the outside of the drill bit on the handheld drill body 1.

[0024] In this embodiment: the processing mechanism includes an elastic telescopic component, and a sealing component is provided on the outside of the elastic telescopic component. The elastic telescopic component includes a fixed plate 21 fixed to one side of the drilling end of the handheld drilling machine body 1. Sliding columns 22 are evenly distributed around the circumference of the fixed plate 21. The sliding columns 22 are arranged parallel to the drilling bit. A support ring 23 is provided at the end of the sliding column 22 located above the drill bit. A spring 24 is sleeved on the sliding column 22 between the support ring 23 and the fixed plate 21. A flange is provided at the other end of the sliding column 22 passing through the fixed plate 21. A through hole is opened at the lower position of the fixed plate 21, and an exhaust fan 211 is installed in the through hole. The sliding column 22 is slidably connected to the fixed plate 21, and the sliding column 22 is threadedly connected to the support ring 23. When the drill bit of the handheld drilling machine body 1 is drilled into the wall, the support ring 23 moves closer to the handheld drilling machine body 1 under the support of the sliding column 22, compressing the spring 24, so that the sealing component seals the drilling area.

[0025] The sealing assembly includes a first hook and loop knitted surface 25 and a second hook and loop knitted surface 26, respectively fixed to the opposing surfaces of the support ring 23 and the fixing plate 21. A serpentine sleeve 27 is provided between the first hook and loop knitted surface 25 and the second hook and loop knitted surface 26. Both ends of the serpentine sleeve 27 are provided with hook and loop loop surfaces 28. The lower end of the serpentine sleeve 27 is connected to a collection bag 29. An annular groove 231 is provided on the end face of the support ring 23 away from the sliding post 22. A rubber ring 210 is installed in the annular groove 231. The rubber ring 210 is flared outwards, allowing it to adhere to the wall surface and preventing contamination during drilling. The serpentine sleeve 27 is integrally formed with the collection bag 29. The serpentine sleeve 27 is made of transparent material, making it easy to observe the drilling process. The serpentine sleeve 27 is fixed between the fixing plate 21 and the support ring 23 by the adhesion of the hook and loop fasteners 28 at both ends of the serpentine sleeve 27 to the first hook and loop fastener knitted surface 25 and the second hook and loop fastener knitted surface 26, thus collecting dust during the drilling process.

[0026] The working principle and usage process of this utility model: Hold the handheld punching machine body 1 and push the rubber ring 210 against the wall to be punched. Align the drill bit with the punching position and make the drill bit of the handheld punching machine body 1 punch a hole in the wall. During the punching process, the support ring 23 moves closer to the handheld punching machine body 1 under the support of the sliding column 22, compressing the spring 24, so that the waste generated during punching enters the serpentine sleeve 27 and falls into the collection bag 29, avoiding dust pollution to the wall surface. After punching, rotate the sliding column 22 to separate the support ring 23, so that the hook and loop fasteners 28 at both ends of the serpentine sleeve 27 separate from the first hook and loop fastener knitted surface 25 and the second hook and loop fastener knitted surface 26. Remove the serpentine sleeve 27 and the collection bag 29 and clean the dust inside.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
