[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] Example 1, reference Figure 1-Figure 5 This embodiment provides a dust-proof device for drilling holes in a building wall, including a dust-proof shell 1 and a drilling machine 2.

[0037] Furthermore, a guide frame 16 is fixedly installed on the inner wall of the dustproof shell 1, a fixing ring 39 is arranged at the center of the guide frame 16, a rotating rod 38 is rotatably installed inside the guide frame 16, the fixing ring 39 is fixedly installed on the surface of the rotating rod 38, one end of the rotating rod 38 passes through the surface of the dustproof shell 1 and extends outward, one end of the rotating rod 38 is fixedly connected to a gear 381, one side of the bar block 34 is fixedly connected to a rack 37, the rack 37 is meshed with the gear 381, the trigger block 33 and the bar block 34 are both trapezoidal block structures, the trigger block 33 is provided with a first inclined surface 33a on the side of the bar block 34, the bar block 34 is provided with a second inclined surface 34a on the side of the trigger block 33, the first inclined surface 33a and the second inclined surface 34a constitute a sliding guide cooperation, the surface of the bar block 34 An extension strip 341 is fixedly connected, a support plate 35 is fixedly connected to the surface of the dustproof shell 1, a sliding rod 36 is fixedly connected to the support plate 35, a plurality of sliding rods 36 are provided, one end of the sliding rod 36 away from the support plate 35 is fixedly connected to the limiting strip 362, the extension strip 341 is sleeved on the surface of the sliding rod 36, the extension strip 341 and the sliding rod 36 form a sliding guide cooperation along the axial direction of the sliding rod 36, a compression spring 361 is sleeved on the surface of the sliding rod 36, one end of the compression spring 361 is fixedly connected to the side of the support plate 35 toward the extension strip 341, and the other end of the compression spring 361 is fixedly connected to the side of the extension strip 341 away from the limiting strip 362, and the elastic force of the compression spring 361 can drive the extension strip 341 to move in the direction close to the limiting strip 362.

[0038] When in use, the drill bit 21 of the drilling machine 2 rotates around its own axis, the staff fits the dust cover 1 against the wall, and pushes the drilling machine 2 to move inside the dust cover 1, the drilling machine 2 moves and drives the moving plate 11 to move synchronously along the guide rod 14 toward the direction close to the positioning step 13, the reset spring 141 contracts under the squeezing of the moving plate 11, the elastic force of the reset spring 141 increases, the moving plate 11 moves and drives the trigger block 33 to move synchronously toward the direction close to the rotating rod 38 through the connecting rod 31 and the connecting frame 32, and under the cooperation of the first inclined surface 33a and the second inclined surface 34a, the extension strip 341 on the strip block 34 moves along the sliding rod 3 6 moves in the direction away from the limit strip 362, the compression spring 361 contracts under the pressure of the extension strip 341, the elastic force of the compression spring 361 increases, the strip block 34 moves and drives the rotating rod 38 to rotate around its own axis through the rack 37 and the gear 381, the rotating rod 38 rotates and drives the fixing ring 39 to rotate synchronously around the axis of the rotating rod 38, and the fixing ring 39 rotates while adjusting the position of the dust removal mechanism 4, the dust removal mechanism 4 releases the obstruction to the drill bit 21, and the staff continues to push the drilling machine 2. At this time, the first inclined surface 33a is separated from the second inclined surface 34a, and the bottom of the trigger block 33 slides along the top of the strip block 34. During the drilling process, the movement of the trigger block 33 no longer pushes the bar block 34 to move. The bar block 34 remains in a fixed position under the squeezing of the trigger block 33, and the overall position of the rotating rod 38 and the fixing ring 39 also remains fixed. After that, the drill bit 21 gradually drills into the wall, and the dust and impurities generated during the drilling process enter the dustproof shell 1, and the dust removal mechanism 4 just absorbs these dust and impurities. After the drilling is completed, the staff releases the push on the drilling machine 2, and the elastic force of the reset spring 141 drives the moving plate 11 to move along the guide rod 14 in the direction away from the positioning step 13, and the drilling machine 2 also returns to the initial position. In this process, the moving plate 11 moves and drives the trigger The trigger block 33 moves synchronously, and the bottom of the trigger block 33 first slides along the top of the strip block 34, and then the first inclined surface 33a contacts the second inclined surface 34a again. During the sliding of the first inclined surface 33a along the second inclined surface 34a, the elastic force of the compression spring 361 drives the extension bar 341 to move along the sliding rod 36 toward the direction close to the limit bar 362, and the strip block 34 moves and drives the fixing ring 39 to rotate synchronously around the axis of the rotating rod 38 through the rack 37 and the gear 381. The fixing ring 39 adjusts the position of the dust removal mechanism 4 again, so that the dust removal mechanism 4 is aligned with the hole just punched in the wall, and the impurities in the hole are sucked out by the dust removal mechanism 4.

[0039] In summary, before the drill bit 21 enters the wall, the trigger block 33 and the strip block 34 cooperate to convert the thrust of the drilling machine 2 into the rotational force of the rotating rod 38. Under the traction of the rotating rod 38, the dust removal mechanism 4 can automatically release the obstruction to the drill bit 21. In the process of the drill bit 21 entering the wall, the sputtered dust and impurities all enter the dustproof shell 1, and the dust removal mechanism 4 can just absorb the dust and impurities. When the drill bit 21 moves back to the initial position from the wall, under the traction of the rotating rod 38, the dust removal mechanism 4 can automatically move and align with the hole in the wall, so as to accurately absorb the impurities remaining in the hole, and the entire dust removal process can be ended together with the drilling.

[0040] Example 2, reference Figure 1-Figure 9 This embodiment provides a dust removal mechanism 4 for filtering and removing dust and impurities. The dust removal mechanism 4 includes an air pump 41, a dust removal box 42 and a dust suction nozzle 43. The input end of the dust removal box 42 is fixedly connected to the dust suction nozzle 43 through a hose 44, and the output end of the dust removal box 42 is fixedly connected to the input end of the air pump 41. A filter assembly 45 is installed inside the dust removal box 42.

[0041] Furthermore, the dust nozzle 43 is fixedly installed inside the fixing ring 39, the vacuum pump 41 and the dust removal box 42 are both fixedly installed on the surface of the dustproof shell 1, the hose 44 runs through the dustproof shell 1, and an opening and closing opening is provided on the surface of the dust removal box 42, and a closed door 46 is installed at the opening and closing opening. The closed door 46 is fixed to the opening and closing opening by magnet adsorption. The staff can remove the closed door 46 from the opening and closing opening, and then take out the filter assembly 45 as a whole from the opening and closing opening.

[0042] Furthermore, the filter assembly 45 includes an air collecting hopper 451, one side of which is fixedly connected to an inner ring 452, the other side of which is fixedly connected to a filter rod 453, a plurality of filter rods 453 are evenly arranged, and connecting holes 454 are densely opened on the surface of the filter rods 453, the inner wall of the dust removal box 42 is fixedly connected to an outer ring 421, the outer ring 421 is connected to the input end of the dust removal box 42, and one side of the outer ring 421 is fixedly connected to a magnetic plate 422, which is used to adsorb and fix the air collecting hopper 451.

[0043] During use, under the action of the vacuum pump 41, dust and impurities can be sucked into the hose 44 by the dust nozzle 43, and then the dust and impurities pass through the hose 44 into the filter assembly 45 inside the dust removal box 42. The dust and impurities cannot pass through the connecting hole 454 on the surface of the filter rod 453, and the air can continue to pass through the connecting hole 454.

[0044] In summary, dust and impurities can be effectively intercepted in the filter rod 453, and the filter assembly 45 is an overall detachable design. When installing the filter assembly 45, the staff can insert the inner ring 452 into the outer ring 421. At this time, under the magnetic attraction of the magnetic plate 422, the air collecting hopper 451 fits tightly with the magnetic plate 422 and the position is fixed. The filter assembly 45 is simple and quick to install and disassemble, which is convenient for the staff to clean and maintain the filter rod 453.

[0045] Example 3, reference Figure 1-Figure 9 This embodiment provides an injection mechanism 5 for cleaning and cooling the drill bit 21, and the injection mechanism 5 includes a water tank 51, an extrusion cylinder 52 and an annular tube 53. The water tank 51 is used to supply water to the extrusion cylinder 52, the extrusion cylinder 52 is used to push water into the annular tube 53, and the annular tube 53 is used to spray water toward the drill bit 21.

[0046] Furthermore, a fixing plate 15 is fixedly installed inside the dustproof shell 1, a fixing cylinder 151 is fixedly connected at the center of the fixing plate 15, an annular tube 53 is fixedly installed on the surface of the fixing cylinder 151, a nozzle 54 is fixedly installed on the inner side of the annular tube 53, a plurality of nozzles 54 are evenly arranged, water in the annular tube 53 can be sprayed toward the nozzle of the drilling machine 2 through the nozzle 54, a water tank 51 is fixedly installed on the fixing plate 15, a loading nozzle 511 is fixedly installed on the surface of the water tank 51, the loading nozzle 511 passes through the inner wall of the dustproof shell 1 and extends outward, and the staff can fill water into the water tank 51 through the loading nozzle 511.

[0047] Furthermore, the extrusion cylinder 52 is fixedly connected to the annular tube 53 via a first water delivery nozzle 58, and the first water delivery nozzle 58 is fixedly connected to the water storage tank 51 via a second water delivery nozzle 59. Both the first water delivery nozzle 58 and the second water delivery nozzle 59 are provided with a one-way valve. The one-way valve inside the first water delivery nozzle 58 is used to prevent the water in the annular tube 53 from flowing back into the extrusion cylinder 52, and the one-way valve inside the second water delivery nozzle 59 is used to prevent the water in the extrusion cylinder 52 from flowing back into the water storage tank 51. The one-way valve is an existing valve technology and will not be described in detail here. The extrusion cylinder 52 is provided with a one-way valve inside. Plug 56, the extrusion cylinder 52 and the piston 56 form a sealed sliding guide fit, and a guide rod 55 is fixedly connected to the center of one side of the piston 56. One end of the guide rod 55 passes through the extrusion cylinder 52 and the inner wall of the dustproof shell 1 and extends outward, and one end of the guide rod 55 is fixedly connected to a pressing handle 57. An auxiliary spring 551 is sleeved on the surface of the guide rod 55, and one end of the auxiliary spring 551 is fixedly connected to the pressing handle 57, and the other end of the auxiliary spring 551 is fixedly connected to the surface of the dustproof shell 1. The elastic force of the auxiliary spring 551 can drive the pressing handle 57 to move in the direction away from the extrusion cylinder 52.

[0048] When in use, if the drill bit 21 needs to be cleaned, the staff pushes the pressing handle 57 by hand, and the pressing handle 57 moves and drives the piston 56 to squeeze the water in the extrusion cylinder 52 through the guide rod 55. The auxiliary spring 551 contracts under the squeezing of the pressing handle 57, and the elastic force of the auxiliary spring 551 increases. Under the action of water pressure, the water passes through the one-way valve in the first water delivery nozzle 58 and enters the annular tube 53. The water in the annular tube 53 is then sprayed toward the drill bit 21 by the nozzle 54. At the same time, the staff pushes the drilling machine 2 to make the moving plate 11 move closer to the positioning step 1. 3, the drill bit 21 also moves synchronously, and all parts of the drill bit 21 are cleaned by water. When the piston 56 pushes out all the water in the extrusion cylinder 52, the staff releases the pressing handle 57, and the elastic force of the auxiliary spring 551 drives the pressing handle 57 to move away from the extrusion cylinder 52 and return to the initial position. The piston 56 also moves synchronously along the inside of the extrusion cylinder 52. At this time, the inside of the extrusion cylinder 52 is in a negative pressure state. Under the action of atmospheric pressure, the water in the water storage tank 51 passes through the one-way valve in the second water delivery nozzle 59 and enters the extrusion cylinder 52.

[0049] In summary, the staff can squeeze the pressing handle 57 by hand to make the water in the extrusion cylinder 52 spray from the nozzle 54 to the drill bit 21. In this process, by pushing the drilling machine 2, any part of the drill bit 21 can be exposed to water, making the cleaning of the drill bit 21 simple and quick. In addition, the water can also dissipate the heat of the drill bit 21, thereby increasing the durability of the drill bit 21. When the water in the extrusion cylinder 52 is exhausted, the water in the water tank 51 can automatically enter the extrusion cylinder 52, thereby realizing a continuous supply of water.

[0050] refer to Figure 1-Figure 9 The working principle of the present invention is as follows: during actual operation, the drilling machine 2 is turned on, the drill bit 21 rotates around its own axis, the staff fits the dust cover 1 between the wall and pushes the drilling machine 2 to move inside the dust cover 1, the drilling machine 2 moves and drives the moving plate 11 to move synchronously along the guide rod 14 toward the direction close to the positioning step 13, the return spring 141 contracts under the pressure of the moving plate 11, the elastic force of the return spring 141 increases, the moving plate 11 moves and drives the trigger block 33 to move synchronously toward the direction close to the rotating rod 38 through the connecting rod 31 and the connecting frame 32, and the first inclined surface 33 Under the cooperation of a and the second inclined surface 34a, the extension bar 341 on the strip block 34 moves along the sliding rod 36 in the direction away from the limit bar 362, and the compression spring 361 contracts under the squeezing of the extension bar 341. The elastic force of the compression spring 361 increases, and the strip block 34 moves and drives the rotating rod 38 to rotate around its own axis through the rack 37 and the gear 381. The rotating rod 38 rotates and drives the fixing ring 39 and the dust nozzle 43 to rotate synchronously around the axis of the rotating rod 38 as a whole. The dust nozzle 43 rotates to the inside of the dustproof shell 1. At this time, the dust nozzle 43 releases the obstruction to the drill bit 21.

[0051] The staff continues to push the drilling machine 2. At this time, the first inclined surface 33a and the second inclined surface 34a are separated, and the bottom of the trigger block 33 slides along the top of the strip block 34. During this process, the movement of the trigger block 33 no longer drives the strip block 34 to move. The strip block 34 remains fixed under the squeezing of the trigger block 33, and the overall position of the rotating rod 38, the fixing ring 39 and the dust suction nozzle 43 also remains fixed. After that, the drill bit 21 gradually drills into the wall. The dust and impurities generated during the drilling process enter the dustproof shell 1. Under the action of the vacuum pump 41, the dust and impurities are sucked into the hose 44 by the dust suction nozzle 43. Then, the dust and impurities pass through the hose 44 and enter the filter assembly 45 inside the dust removal box 42. The surface of the filter rod 453 of the filter assembly 45 is densely provided with connecting holes 454. These dust and impurities cannot pass through the connecting holes 454 and are intercepted in the filter rod 453.

[0052] After the drilling is completed, the staff releases the push on the drilling machine 2, and the elastic force of the reset spring 141 drives the moving plate 11 to move along the guide rod 14 in the direction away from the positioning step 13, and the drilling machine 2 also returns to the initial position. During this process, the moving plate 11 moves and drives the trigger block 33 to move synchronously. The bottom of the trigger block 33 first slides along the top of the strip block 34, and then the first inclined surface 33a and the second inclined surface 34a contact each other again. During the sliding of the first inclined surface 33a along the second inclined surface 34a, the elastic force of the compression spring 361 drives the extension bar 341 to move along the sliding rod 36 in the direction close to the limit bar 362, and the strip block 34 moves and drives the rotating rod 38 to rotate around its own axis through the rack 37 and the gear 381, and the dust nozzle 43 also rotates synchronously and returns to the initial position. At this time, the dust nozzle 43 is aimed at the hole just drilled in the wall, and the impurities in the hole are accurately sucked out by the dust nozzle 43.
