Description

Technical Field

[0001] This utility model relates to the field of drilling technology, and in particular to a dust and chip collection cover for drilling holes in walls. Background Technology

[0002] A dust and debris hood is a device used to collect dust and debris when drilling into walls or concrete structures, designed to reduce environmental pollution and protect the health of operators.

[0003] Because drilling machines come in various sizes, existing dust and chip collection covers are typically placed directly on the drill bit to fit most machines. This makes it impossible to adjust the dust and chip collection cover to fit the size of the drilling machine, resulting in some machines being incompatible with the purchased dust and chip collection cover. Furthermore, the dust generated by the existing dust and chip collection cover falls directly into the cover after use, which may lead to dust spilling onto the ground due to operator error, increasing unnecessary workload. Therefore, a new dust and chip collection cover for wall drilling is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a dust and chip collection cover for drilling holes in walls, which aims to improve the problems of existing technology that it is not easy to adapt to any machine size and that dust is easy to scatter after collection.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a dustproof and chip collection cover for drilling holes in walls, comprising an outer shell, a sliding sleeve slidably connected to the inner wall of the outer shell, the outer wall of the sliding sleeve being elastically connected to the inner wall of the outer shell by a first spring, a locking device being provided on the outer wall of the sliding sleeve, and a collection device being provided on the inner wall of the outer shell.

[0006] The locking device includes a threaded sleeve, which is fixedly connected to the outer wall of the sliding sleeve. A rotating sleeve is threadedly connected to the outer wall of the threaded sleeve. A connecting rod is slidably connected to the inner wall of the threaded sleeve. An inclined clamping block is fixedly connected to the outer wall of the connecting rod. The inclined clamping block is elastically connected to the inner wall of the threaded sleeve by a second spring.

[0007] As a further description of the above technical solution: the collecting device includes a semi-circular funnel, which is fixedly connected to the inner wall of the outer shell, and a collecting bottle is threadedly connected to the inner wall of the bottom end of the outer shell.

[0008] As a further description of the above technical solution: one end of the first spring is fixedly connected to the inner wall of the outer casing, and the other end of the first spring is fixedly connected to the outer wall of the sliding sleeve.

[0009] As a further description of the above technical solution: the inclined clamping blocks are provided in four sets, and the four sets of inclined clamping blocks are slidably connected to the inner wall of the threaded sleeve.

[0010] As a further description of the above technical solution: the outer wall of the sliding sleeve is provided with a guide block.

[0011] As a further description of the above technical solution: one end of the second spring is fixedly connected to the inner wall of the threaded sleeve, and the other end of the second spring is fixedly connected to the inner wall of the inclined clamping block.

[0012] As a further description of the above technical solution: a groove is provided at the bottom of the outer shell.

[0013] As a further description of the above technical solution: the mouth of the collection bottle is threaded.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by twisting the rotating sleeve, the rotating sleeve moves along the thread of the outer wall of the threaded sleeve. By squeezing the inclined surface of the inclined clamping block by the rotating sleeve, the inclined clamping block approaches the drill housing, so that it can be adapted to drills of any size, thereby improving the problem of the prior art that it is not convenient to adapt to any machine size.

[0016] 2. In this utility model, the dust generated during drilling falls into the semi-circular funnel and is collected in the collection bottle through the semi-circular funnel, making it less likely to spill, thereby improving the problem of dust easily scattering after collection in the prior art.

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] Reference Figures 1-2 As shown, one embodiment of this utility model provides a dustproof and chip-collecting cover for wall drilling, including an outer shell 1. The outer shell 1 can cover the drilling position to prevent dust from scattering during machine drilling. A sliding sleeve 2 is slidably connected to the inner wall of the outer shell 1. The sliding sleeve 2 can push the machine inside the outer shell 1 during drilling. A guide block is provided on the outer wall of the sliding sleeve 2 to ensure the stability of the sliding sleeve 2 when moving back and forth. The outer wall of the sliding sleeve 2 is elastically connected to the inner wall of the outer shell 1 by a first spring 3. One end of the first spring 3 is fixedly connected to the inner wall of the outer shell 1, and the other end of the first spring 3 is fixedly connected to the outer wall of the sliding sleeve 2. The first spring 3 can reset the pushed sliding sleeve 2 after drilling is finished. A locking device 4 is provided on the outer wall of the sliding sleeve 2 to fix the dustproof and chip-collecting cover to a drilling machine of any size. A collection device 5 is provided on the inner wall of the outer shell 1 to collect the dust scattered during drilling.

[0026] Reference Figure 3As shown, the locking device 4 includes a threaded sleeve 41. The threads on the outer wall of the threaded sleeve 41 can self-lock the rotating sleeve 42 to ensure that the rotating sleeve 42 is fixed when it stops rotating. The threaded sleeve 41 is fixedly connected to the outer wall of the sliding sleeve 2. The rotating sleeve 42 is threadedly connected to the outer wall of the threaded sleeve 41. The rotating sleeve 42 rotates along the threaded sleeve 41 to press the inclined surface of the inclined clamping block 44 to clamp and fix it to the machine. A connecting rod 43 is slidably connected to the inner wall of the threaded sleeve 41. The connecting rod 43 ensures the stability of the inclined clamping block 44 when it moves up and down. The inclined clamping block 44 is fixedly connected to the outer wall of the connecting rod 43. There are four sets of inclined clamping blocks 44, and the four sets of inclined... The face clamp 44 is slidably connected to the inner wall of the threaded sleeve 41. The bottom of the inclined face clamp 44 has a rubber gasket to ensure that the inclined face clamp 44 is locked stably to the machine. The outer inclined surface of the inclined face clamp 44 can press the inclined face clamp 44 down to fix the machine when the rotating sleeve 42 rotates. The inclined face clamp 44 is elastically connected to the inner wall of the threaded sleeve 41 by the second spring 45. One end of the second spring 45 is fixedly connected to the inner wall of the threaded sleeve 41, and the other end of the second spring 45 is fixedly connected to the inner wall of the inclined face clamp 44. The second spring 45 ensures that it can automatically return to the upper position after the rotating sleeve 42 releases the fixation of the inclined face clamp 44.

[0027] Reference Figures 4-5 As shown, the collection device 5 includes a semi-circular funnel 51, which can collect dust scattered during drilling. The semi-circular funnel 51 is fixedly connected to the inner wall of the outer shell 1. A groove is provided at the bottom of the outer shell 1. A collection bottle 52 is threadedly connected to the inner wall at the bottom of the outer shell 1. The mouth of the collection bottle 52 is threaded. The collection bottle 52 can contain the dust collected by the semi-circular funnel 51 and can be disassembled and cleaned after a certain weight of dust has been contained.

[0028] When using this utility model, the drill is first placed in the threaded sleeve 41. By twisting the rotating sleeve 42, the rotating sleeve 42 moves along the thread on the outer wall of the threaded sleeve 41. The rotating sleeve 42 presses the inclined surface of the inclined clamping block 44, so that the inclined clamping block 44 approaches the drill housing until it is clamped and fixed, thus completing the installation of the dustproof chip collection cover for the drill. When dust needs to be collected, the outer housing 1 is pressed against the wall when drilling, and the dust generated falls into the semi-circular funnel 51, which is then collected in the collection bottle 52.
