The equipment is small in size and flexible to use, so its application range is very wide.

[0003] When drilling holes with existing water drills, the existing water drills have no positioning function, so when drilling holes in walls, the drilling holes are easily deviated, and inertia is generated at the moment the holes are drilled through. The generated inertia will cause the user to push the water drill further toward the wall, which may easily cause the diameter of a portion of the drilled hole to be larger or the drilled hole to deviate, causing inconvenience to subsequent installation. When drilling holes with existing water drills, mud will flow out of the drilled hole and fall along the wall, causing mud and sand to adhere to the wall, making it difficult to clean and causing inconvenience to subsequent decoration.

DETAILED DESCRIPTION

[0026] 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Specific embodiments

[0028] A drilling device with anti-deviation function for construction engineering, such as Figure 1 and Figure 2 As shown, it includes a water drill punch 1, a connecting pipe 2, a drill bit 3, a limiting mechanism 4 and a positioning mechanism 5. The water drill punch 1 is provided with a connecting pipe 2, and the lower part of the connecting pipe 2 is threadedly connected with the drill bit 3. The lower part of the water drill punch 1 is provided with a limiting mechanism 4, and the limiting mechanism 4 is used to prevent the inertia generated when drilling a hole from causing the drill bit to approach the wall and cause deviation. The limiting mechanism 4 is slidably matched with the drill bit 3, and a positioning mechanism 5 is provided in the drill bit 3. The positioning mechanism 5 is used to locate the center point of the drill hole to avoid deviation of the drill hole.

[0029] When it is needed, the user uses the handheld water drill punch 1 to move the drill bit 3 to the position where a hole needs to be drilled. At this time, the user connects the external water inlet pipe and the external water outlet pipe to the limiting mechanism 4 respectively, and then the user holds the water drill punch 1 to work. The water drill punch 1 works to make the drill bit 3 rotate. While the drill bit 3 rotates, the user makes the water drill punch 1 approach the wall surface to be drilled, so that the drill bit 3 rotates and penetrates into the wall surface to perform a hole drilling operation. At the same time, water is sent into the limiting mechanism 4 through the external water inlet pipe, and the water in the limiting mechanism 4 flows out through the drill bit 3, so as to avoid a large amount of dust when the drill bit 3 drills a hole in the wall. At the same time, the drill bit 3 is cooled by water. As the drill bit 3 continues to penetrate into the wall surface, the positioning mechanism 5 is used to prevent the drilling hole from deviating, and the drill bit 3 3 rotates while driving the limiting mechanism 4 to work. The limiting mechanism 4 collects and separates the mud generated during drilling, separates the water and sediment in the mud, and discharges the separated water through the external water outlet pipe, so as to prevent the sediment from falling on the wall and causing inconvenience to the subsequent wall decoration. After the drilling is completed, it will approach the wall under the action of inertia. At this time, the limiting mechanism 4 is used to avoid the phenomenon of approaching the wall at the moment of drilling. Then the user uses the water drill punch 1 to make the drill bit 3 rotate in the opposite direction. When the drill bit 3 moves out of the drill hole, the user turns off the water drill punch 1. When drilling is needed again, the user repeats the above operation. When drilling is not needed, the user removes the external water inlet pipe and the external water outlet pipe from the limiting mechanism 4 respectively.

[0030] like Figure 2-4As shown, the limiting mechanism 4 includes a mounting plate 401, a sleeve 402, a slide rod 403, a fastening bolt 404, a limiting plate 405, a first spring 406, an annular hollow plate 407, a water outlet 408, an annular receiving plate 409, a handle 410, a water inlet 411 and a water supply pipe 412. The mounting plate 401 is connected to the lower part of the water drill 1, and the mounting plate 401 is located on the upper side of the drill bit 3. The left and right parts of the lower surface of the mounting plate 401 are both installed with sleeves 402, and the left and right parts of the mounting plate 401 are respectively slidably provided with slide rods 403. The slide rods 403 on the left and right sides are connected to the mounting plate 401. 3 slides in the sliding sleeves 402 on the left and right sides respectively, and the rear side wall of the sliding sleeve 402 is threadedly connected with a fastening bolt 404, and the fastening bolt 404 is used to fix the sliding rod 403, so that holes of different depths can be drilled, and the fastening bolt 404 contacts and cooperates with the sliding rod 403. The lower ends of the sliding rods 403 on the left and right sides are installed with limit plates 405, and the limit plates 405 are used for positioning to prevent the inertia generated when drilling holes from causing the drill to approach the wall, resulting in deviation of the drill bit. The left and right parts of the lower surface of the limit plate 405 are both installed with first springs 406, and the first springs 406 on the left and right sides are installed with first springs 406 on the left and right sides. 06 is provided with an annular hollow plate 407 at the lower end, and the outer side of the annular hollow plate 407 is connected with a water outlet 408, and the annular hollow plate 407 cooperates with the water outlet 408 to facilitate the discharge of the separated water through the external water outlet pipe, and an annular holding plate 409 is slidably provided on the inner side of the annular hollow plate 407, and a plurality of groups of water outlet holes are opened in the circumferential direction of the outer side of the annular holding plate 409, and a group of water outlet holes is three arranged vertically, and the annular holding plate 409 is used to collect the outflowing mud, and the centrifugal force generated by the rotation of the annular holding plate 409 separates the mud into water and sediment, and separates the separated mud into water and sediment. The water is thrown into the annular hollow plate 407 through the water outlet of the annular holding plate 409 by centrifugal force, which facilitates the discharge of the separated water and prevents the mud from sliding through the wall, causing part of the mud and sand to adhere to the wall and hinder the subsequent cleaning. The annular holding plate 409 is slidably matched with the outer side surface of the drill bit 3, and a handle 410 is provided on the left side of the mounting plate 401. The front side of the mounting plate 401 is connected to a water inlet 411, and the water inlet 411 is connected to the connecting pipe 2. Water supply pipes 412 are embedded on the left and right sides of the drill bit 3, and the water supply pipes 412 on the left and right sides are respectively connected to the connecting pipe 2.

[0031] like Figure 5-8As shown, the positioning mechanism 5 includes a telescopic tube 501, a positioning plate 502, a positioning block 503, a second spring 504, a positioning rod 508, a toggle rod 509 and a third spring 510. The top of the drill bit 3 is provided with a telescopic tube 501, and the telescopic tube 501 is located inside the water supply pipe 412 on the left and right sides. The inner lower part of the telescopic tube 501 is slidably provided with a positioning plate 502, and the positioning plate 502 is located in the drill bit 3. The outer annular surface of the positioning plate 502 is slidably sealed with the inner surface of the drill bit 3 to prevent the mud generated during drilling from entering the telescopic tube 501. The center position of the lower surface of the positioning plate 502 is connected with a positioning block 503, and the positioning block 503 is a circular frustum. The positioning block 503 is used to locate the center point of the drill hole to avoid deviation during drilling, which makes the subsequent installation work of the drill hole inconvenient. The second spring 504 is fixedly connected between the positioning plate 502 and the drill bit 3, and the second spring 504 is located in the telescopic tube 501. The left and right parts of the inner surface are provided with a plurality of slots 505, and the slots 505 on the same side are arranged vertically. The left and right parts of the lower surface of the positioning plate 502 are provided with upwardly extending slide grooves 506, and the left and right parts of the positioning plate 502 are provided with inwardly extending slide holes 507. The adjacent slide grooves 506 and slide holes 507 are connected, and a positioning rod 508 is slidably provided in the slide hole 507. The positioning rods 508 on the left and right sides are both embedded with spherical blocks. The spherical block 508 cooperates with the card slot 505 to prevent the positioning block 503 from deviating from the center point of the drill hole. The positioning rod 508 is fixedly connected with a toggle rod 509. The toggle rods 509 on the left and right sides slide in the slide grooves 506 on the left and right sides respectively. A third spring 510 is fixedly connected between the positioning rod 508 and the positioning plate 502. The third springs 510 on the left and right sides are respectively located in the slide holes 507 on the left and right sides.

[0032] When using the device for drilling, the user connects the external water inlet pipe and the external water outlet pipe to the water inlet 411 and the water outlet 408 respectively, and then the user rotates the fastening bolt 404 to release the fixation of the sliding rod 403, the user moves the sliding rod 403 up and down to a suitable position, and then the user rotates the fastening bolt 404 to fix the sliding rod 403, and the user then holds the water drill punch 1 and holds the handle 410 to make the drill bit 3 located at the position where the hole needs to be drilled on the wall, and makes the positioning block 503 located at the center point of the hole to be drilled. At this time, the annular hollow plate 407 and the annular holding plate 409 are tightly attached to the wall through the first spring 406, and then the user supplies water through the external water inlet pipe, and then the user operates the water drill punch 1 to work, and the water drill punch 1 works to provide the power for the drill bit 3 to rotate, and at the same time the user makes the water drill punch 1 approach the wall surface to be drilled, so that the drill bit 3 rotates and penetrates into the wall surface to be drilled, and the wall is drilled in this way. The water inlet 411 and the connecting pipe 2 supply water to the water supply pipe 412, and the water in the water supply pipe 412 flows onto the drill bit 3. When the drill bit 3 drills a hole in the wall, mud will be generated. The generated mud flows out along the hole drilled by the drill bit 3. At this time, since the annular hollow plate 407 is in close contact with the wall, the mud that flows out falls into the annular receiving plate 409. The rotation of the drill bit 3 drives the annular receiving plate 409 to rotate. The centrifugal force generated by the rotation of the annular receiving plate 409 The mud in the annular holding plate 409 is separated into water and silt. The centrifugal force generated by the rotation of the annular holding plate 409 throws the separated water out through the water outlet hole on the annular holding plate 409 into the annular hollow plate 407. The water in the annular hollow plate 407 then flows out through the water outlet 408 and the external water outlet pipe. Since the outer annular surface of the positioning plate 502 and the inner surface of the drill bit 3 are slidingly sealed, the mud generated during drilling is prevented from entering the telescopic tube 501.

[0033] As the drill bit 3 continues to penetrate into the wall, the stone produced by drilling in the drill bit 3 will squeeze the positioning block 503, the positioning block 503 squeezes the positioning disk 502, the telescopic tube 501 shrinks accordingly and the second spring 504 is compressed, the drill bit 3 penetrates into the wall and causes the positioning rod 508 to move out of the slot 505. When the positioning rod 508 moves out of the slot 505, the third spring 510 is compressed accordingly. When the positioning rod 508 is again inserted into the slot 505, the third spring 510 is reset accordingly, and this is repeated continuously. Through the cooperation of the positioning rod 508 and the slot 505, it is convenient to position the positioning disk 502. At the same time, the center point is positioned by the positioning block 503 to prevent the center point of the drilling hole from deviating. When the drilling hole is opened, there will be inertia approaching the wall. At this time, the limit plate 405, the first spring 406 and the annular hollow plate 407 cooperate to block the generated inertia to prevent the user from approaching the wall, causing the drill bit 3 to deviate. After the drilling is completed, the user The water drill 1 is operated to make the drill bit 3 rotate in the opposite direction and move out of the drill hole. When the drill bit 3 moves out of the drill hole, the user turns off the water drill 1 and stops supplying water to the water supply pipe 412. Then the user cleans the stones in the drill bit 3 and brings the toggle rods 509 on both sides closer together. The toggle rods 509 on both sides bring the positioning rods 508 on both sides closer together. The positioning rods 508 on both sides move closer together and then move into the sliding holes 507 on both sides respectively. The third spring 510 is compressed accordingly. The positioning rods 508 on both sides move out of the slots 505. At this time, the positioning plate 502 moves and resets under the action of the second spring 504. Then the user releases the toggle rods 509 on both sides. In this way, the positioning rods 508 are reset and snapped into the corresponding slots 505 under the action of the third spring 510. When drilling is needed again, the user repeats the above operation. When drilling is not needed, the user removes the external water inlet pipe and the external water outlet pipe from the water inlet 411 and the water outlet 408 respectively.

[0034] like Figure 2 As shown, a buffer mechanism 6 is also included, and the buffer mechanism 6 includes a fixed plate 601, a support rod 602 and a spring plate 603. The upper part of the water drill punch 1 is provided with a fixed plate 601, the upper surface of the fixed plate 601 is connected to the support rod 602, and the upper end of the support rod 602 is provided with a spring plate 603. When drilling with this device, the user makes the spring plate 603 contact with the user's shoulder, so that the vibration generated during drilling is buffered by the spring plate 603. At the same time, the user uses the shoulder to force the water drill punch 1 to move closer to the wall that needs to be drilled, so that it is convenient to drill holes on the wall.

[0035] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
