Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a dust collector for wall construction and a use method thereof. Background Art

[0002] During wall construction, it is often necessary to drill holes on the wall, and the drilling is usually done with an electric drill.

[0003] When drilling, a large amount of dust will diffuse into the air. When the operator is working, he is very close to the working point. The dust diffusion will cause the operator to inhale the dust, which will cause discomfort to the operator. People who work for a long time are more likely to have adverse effects on their health. Therefore, some current electric drills are equipped with dust covers to prevent dust diffusion.

[0004] For example, a Chinese patent with authorization announcement number CN217775652U discloses a dust collection device for drilling holes on a wall or ceiling, in which a dust cover is installed on an electric drill, and the dust cover is detachably connected to the electric drill. However, since a certain vibration is generated when drilling holes in the wall, the vibration of the electric drill will transmit the vibration to the dust cover, causing the dust cover to be easily affected by the vibration and become unstable, and may even fall from between the electric drill and the wall, affecting the operator's work.

[0005] Therefore we propose a ash collector for wall construction and a method of use thereof, so as to solve the above-mentioned problems.

[0066] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. It should be pointed out that the drawings are schematic and not drawn to scale. For the sake of clarity and convenience in the figures, the relative sizes and proportions of the parts shown in the figures are exaggerated or reduced in size, and any size is only exemplary and not restrictive.

[0067] Embodiment 1:

[0068] See also Figure 1-Figure 6A dust collector for wall construction and a method of using the same include: a dust collecting hood 1, a movable sleeve 2, a fixing assembly 3, a collecting assembly 4 and an air suction pipe 5; the dust collecting hood 1 includes a hood body 11 and a fixing ring 12, the fixing ring 12 is fixedly mounted on the periphery of one end of the hood body 11, and a leakage channel 13 is also provided at the bottom end of the hood body 11; the movable sleeve 2 includes a telescopic sleeve 21, the telescopic sleeve 21 is movably sleeved in the gap between the hood body 11 and the fixing ring 12, a limiting sleeve 22 is fixedly mounted on one end of the telescopic sleeve 21 away from the hood body 11, the limiting sleeve 22 is located outside the fixing ring 12, and a first spring 23 is further provided on the outer surface of the telescopic sleeve 21, and two ends of the first spring 23 are provided The ends are respectively fixed to the telescopic ring 21 and the fixed ring 12; the fixed component 3 includes a movable ring 31, which is movably sleeved on the limit ring 22, and the movable ring 31 is rotatably connected to two rotating rods 32, and an upper limit rod 33 is fixedly installed between the two rotating rods 32, and the end of the rotating rod 32 away from the movable ring 31 is also rotatably connected to a connecting rod 34, and the connecting rod 34 is also elastically connected to a movable rod 35 through a second spring 36, and the movable rod 35 is fixedly installed with a lower limit rod 37; the collecting component 4 is fixedly installed at the bottom end of the dust collecting hood 1 and is connected to the leakage channel 13; the hood body 11 is also provided with an air inlet hole 7; one end of the suction pipe 5 is fixedly installed on the collecting component 4 and is connected to the collecting component 4.

[0069] In the above technical solution, the bottom end of the suction pipe 5 is connected to the external air purification equipment, and the connection method is a fixed connection or a detachable connection. The existing air purification equipment often has suction devices such as air pumps and fans. Through the operation of these devices, the purification of dusty air can be achieved.

[0070] like Figure 3 As shown, the end of the cover body 11 away from the fixing ring 12 is a curved structure, and the diameter of the cross section gradually increases. When in use, the end away from the fixing ring 12 contacts the wall surface to achieve drilling.

[0071] By adopting the above technical solution, the dust collector for wall construction is more stable after installation. Since the upper limit rod 33 and the lower limit rod 37 clamp the electric drill, even if the vibration of the electric drill is transmitted to the device, it will not cause the cover body 11 to detach from the electric drill, so it has better stability.

[0072] During installation: insert the drill rod of the electric drill into the cover body 11, rotate the rotating rod 32 to make the upper limit rod 33 contact the upper surface of the electric drill, then pull the lower limit rod 37, and rotate the connecting rod 34 to make the lower limit rod 37 bypass the tail end of the electric drill. After loosening the lower limit rod 37, the lower limit rod 37 fits the lower surface of the tail end of the electric drill. When disassembling, pull the lower limit rod 37 to separate it from the electric drill.

[0073] Another advantage is that when in use, the operator only needs to hold the electric drill, control the cover 11 to contact the wall, start the electric drill, and push it toward the wall. The telescopic ring 21 shrinks into the fixed ring 12, and the dust generated during drilling is sucked out from the suction pipe 5, and the debris enters the collection component 4, which can prevent dust from spreading into the air.

[0074] Among them, a handle 6 is also fixedly installed on the fixing ring 12. The operator can hold the handle 6 with one hand and the electric drill with the other hand to work. Holding the handle 6 can keep the position of the device fixed when in use to avoid displacement or rotation caused by vibration generated during drilling.

[0075] like Figure 2 As shown, a shock-absorbing pad 10 is fixedly mounted on a side of the cover body 11 away from the fixing ring 12 to reduce the vibration during drilling and improve the comfort of the operator.

[0076] like Figure 3 As shown, the upper limit rod 33 is a semicircular arc structure, and the middle part of the lower limit rod 37 is a circular arc structure, so as to facilitate installation with an electric drill.

[0077] Please continue reading Figure 3 The collecting assembly 4 includes a material receiving box 41 and a box cover 42 rotatably connected to the bottom surface of the material receiving box 41 ; the material receiving box 41 and the box cover 42 are fastened by an elastic buckle 43 .

[0078] By adopting the above technical solution, when in use, the broken materials enter the material receiving box 41 through the material leakage channel 13, and after the work is completed, the box cover 42 is opened to take out the broken materials. The material receiving box 41 and the box cover 42 are sealed with a sealing gasket to prevent the air with dust from leaking out, and the air with dust enters the suction pipe 5 from the material receiving box 41, and the connection point between the suction pipe 5 and the material receiving box 41 is located above the box cover 42 to avoid the inhalation of larger particles.

[0079] See also Figure 6 In addition, a filter screen is installed in the material receiving box 41 at the interface of the suction pipe 5 to prevent the broken materials from being sucked in.

[0080] Embodiment 2:

[0081] See also Figure 3, which is different from Example 1 in that: in this embodiment, the air suction pipe 5 adopts a metal bellows or other type of pipe in the prior art, has good sealing performance, is bendable, and can still maintain a connected state in a bent state, and, on the basis of Example 1, also includes a pipe storage component 9 for adjusting the length of the air suction pipe 5; the handle 6 includes a hand-held end 61, the hand-held end 61 is provided with an inner cavity, and a side surface of the hand-held end 61 is also provided with a long hole 62; the pipe storage component 9 is arranged in the inner cavity of the hand-held end 61, the air suction pipe 5 penetrates into the inner cavity of the hand-held end 61, and is rolled up in the pipe storage component 9, and penetrates to the outside of the hand-held end 61 through the long hole 62.

[0082] See also Figure 4 , Figure 7-Figure 9 The pipeline storage assembly 9 includes a hollow column 91 and a fixed shaft 94; the fixed shaft 94 is fixedly installed in the inner cavity of the handheld end 61; the hollow column 91 is arranged in the inner cavity of the handheld end 61 and is rotatably connected to the fixed shaft 94; a gear 92 is fixedly installed at one end of the hollow column 91, and a reel 93 is fixedly installed at the gear 92; the pipeline storage assembly 9 also includes a pull rod 95 and a trapezoidal block 96; the pull rod 95 is passed through the handheld end 61, and one end located in the inner cavity of the handheld end 61 is fixed to the trapezoidal block 96, and the pull rod 95 is also sleeved with a first Three springs 97 are provided and located inside the hand-held end 61, with the two ends of the third spring 97 being fixed to the trapezoidal block 96 and the hand-held end 61 respectively; the end face of the trapezoidal block 96 is in contact with one of the teeth of the gear 92; a spring spring 98 is also provided in the inner cavity of the hollow column 91, with the two ends of the spring spring 98 being fixed to the hollow column 91 and the fixed shaft 94 respectively; the air suction pipe 5 is wound around the winding wheel 93, and the teeth of the gear 92 include an arcuate surface 921 and a plane surface 922, and the inclined surface of the trapezoidal block 96 faces the arcuate surface of the teeth of the gear 92.

[0083] Since some holes are located at higher points on the wall when an electric drill is used to drill holes in the wall, the suction pipe 5 needs to have a certain length. The suction pipe 5 can be rolled up in the inner cavity of the handle 6 using the winding wheel 93. When in use, the length of the suction pipe 5 extending out of the handle 6 can be adjusted according to the length of the drilling position to adapt to different drilling positions.

[0084] During adjustment, the operator pulls the pull rod 95 to disengage the teeth of the gear 92 from the trapezoidal block 96, and then pulls the suction tube 5 outward. During the pulling process, the elastic potential energy of the clockwork spring 98 increases. When the length of the pulled suction tube 5 is sufficient, the pull rod 95 is released, and the trapezoidal block 96 contacts the gear 92 again.

[0085] Another advantage of the above technical solution is that it is also convenient to store the suction tube 5. After use, the pull rod 95 is pulled, and under the action of the spring spring 98, the hollow column 91 rotates, driving the winding wheel 93 to rotate, and the suction tube 5 is stored on the winding wheel 93.

[0086] Embodiment 3:

[0087] See also Figure 1 On the basis of embodiment 1, a transparent observation window 8 is further provided, which is fixedly mounted on the cover body 11, so that the operator can observe whether the drill rod is aligned with the position to be drilled when in use.

[0088] A method for using a dust collector for wall construction is applied to a dust collector for wall construction, comprising the following steps:

[0089] Step 1: Insert the end of the electric drill and the drill rod into the limiting collar 22, and rotate the rotating rod 32 to make the upper limit rod 33 contact the electric drill;

[0090] Step 2: Stretch the movable rod 35 and rotate the connecting rod 34 until the lower limit rod 37 contacts the bottom surface of the electric drill;

[0091] Step 3: Attach the cover 11 to the wall to be drilled;

[0092] Step 4: Start the electric drill and push it towards the wall;

[0093] Step 5: Collect dust through the air suction pipe 5 and let air in through the air inlet 7.

[0094] Working principle: first, put one end of the electric drill with the drill rod on the limit collar 22, then rotate the rotating rod 32 until the upper limit rod 33 contacts the electric drill, then pull the lower limit rod 37, and rotate the connecting rod 34. After the lower limit rod 37 passes the end of the electric drill and reaches the bottom of the electric drill, release the lower limit rod 37. The operator pulls the pull rod 95 and adjusts the length of the suction pipe 5. The suction pipe 5 is connected to the external air filtration device, and the device is turned on to start suction. The end where the drill bit is located is aligned with the drilling point until the cover 11 contacts the wall, the electric drill is started, and the electric drill is pushed to drill. The generated dust is absorbed by the suction pipe 5, and the block-shaped debris enters the receiving box 41. After completion, the device is removed from the electric drill, the box cover 42 is opened, and the debris therein can be cleaned.
