A drilling device for the outer wall of a building

Abstract

The present invention relates to the technical field of external wall drilling, and specifically relates to a drilling device for the external wall of a building. Aiming at the possible inclination problem during drilling, the following technical solutions are proposed: The stabilizing component includes a slider installed at the bottom of the auxiliary. A slide bar is installed through the inside of the slider. One end of the slide bar is installed with a stabilizing plate. Four groups of horizontal bars are installed on the inner wall of the stabilizing plate. Four groups of through slots are opened inside the stabilizing plate. One end of each group of through bars is installed with a locking block. When drilling in the present invention, whether the stabilizing plate tilts slightly can be sensed through the states of the four groups of horizontal bars. And if tilting occurs, the slide bar is locked on the slider, so that the drill bit will no longer penetrate deeply, effectively preventing the occurrence of drilling inclination. When the inclination is not detected in time, the movable two-link can apply force to the opening and closing button, which can effectively enable the staff to detect that the drilling is inclined, and then correct the drilling direction.

Description

Technical Field

[0001] The present invention relates to the technical field of external wall drilling, and particularly relates to a drilling device for the external wall of a building. Background Art

[0002] The Chinese Patent Network discloses a publication number of: CN215549879, which discloses a drilling device for the external wall of a building in construction engineering. It includes a support base, one end of the support base is vertically connected with a vertical plate, the end of the vertical plate far from the support base is glued with a protective pad, a chute is opened at the top of the support base, a guide rod is fixed inside the chute, a slider is slidably connected inside the chute, the guide rod penetrates through the slider, a connecting seat is fixed at the top of the slider, a motor is installed on the top of the connecting seat, the output end of the motor is connected with a worm, the end of the worm far from the motor is connected with a drill bit, and one end of the worm is meshed with a worm gear, and the bottom end of the worm gear is connected with a transmission rod. When using the drilling device for the external wall of a building, the drilling device can be held and fixed near the external wall, so that the drill bit automatically moves towards the external wall for drilling, enhancing the stability of drilling.

[0003] When holding this device to drill the external wall, the device relies on the vertical plate to fit with the external wall to ensure that the drill bit is perpendicular to the external wall. However, when holding it by hand, due to factors such as the force generated by drilling or uneven gripping force, the staff cannot ensure that the vertical plate always fits on the external wall, resulting in the possibility of the drill hole being inclined. Summary of the Invention

[0004] The purpose of this part is to outline some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Simplifications or omissions may be made in this part, as well as in the abstract and title of the present application, to avoid obscuring the purpose of this part, the abstract, and the title, and such simplifications or omissions shall not be used to limit the scope of the present invention.

[0005] Aiming at the above-mentioned drawbacks of the prior art, the present invention provides a theme of a drilling device for the external wall of a building, which can effectively solve the problem that the drill hole may be inclined in the prior art.

[0006] To achieve the above purposes, the present invention is realized through the following technical solutions:

[0009] A support spring is installed inside the sliding rod. A support block is installed at one end of the support spring. A moving spherical surface is installed on the outer wall of the support block. A swinging member is installed on the outer wall of the support block.

[0010] The support spring makes the moving spherical surface on the support block contact with the outer wall of the moving block. When the sliding rod moves on the slider, the moving spherical surface moves under the extrusion of the fixed spherical surface.

[0011] The swinging member includes a swinging rod connected to the outer wall of the support block through a pin shaft. A plug rod is connected to one end of the swinging rod through a pin shaft. The plug rod is a rectangular rod, and grooves matching the embedding blocks are provided on all four walls of the rectangular rod.

[0012] An adaptive spring is installed at one end of each locking block. An embedding block is installed at one end of the adaptive spring. When all four embedding blocks are disengaged from the grooves of the plug rod, the plug rod can return to its active state.

[0013] A restoring spring is installed at one end of the horizontal rod. A matching groove is provided on the outer wall of the horizontal rod.

When the opening and closing button is pressed, the active two-link deflects, and one end of the active two-link deflects close to the side of the sliding plate.

[0016] As a preferred solution of the building exterior wall drilling device of the present invention, one end of the plug rod extends into the stabilizing plate, and when the plug rod extends, it passes through one side of the through groove, and all four walls of the plug rod are perpendicular to the four through rods.

[0029] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention may be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

When detailing the embodiments of the present invention, for the sake of convenience in explanation, the cross-sectional views showing the device structure will be enlarged locally out of the general proportion, and the schematic diagrams are only examples and should not limit the scope of protection of the present invention herein. In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0032] Embodiment 1

[0033] Referring to Figures 1 - 4 , which is the first embodiment of the present invention. This embodiment provides a drilling device for the outer wall of a building, including a drilling machine 1, an opening and closing button 11, a clamping member 12, and an auxiliary handle 13. The opening and closing button 11 is the driving button of the drilling machine 1. The clamping member 12 can disassemble and assemble the auxiliary handle 13 according to requirements. A stabilizing component 2 is installed at the bottom of the auxiliary handle 13. The stabilizing component 2 includes a slider 21 installed at the bottom of the auxiliary part. A slide rod 22 is installed through the inside of the slider 21. One end of the slide rod 22 is installed with a stabilizing plate 23. Four horizontal rods 231 are installed on the inner wall of the stabilizing plate 23, and one ends of the horizontal rods 231 all extend out of one side outer wall of the stabilizing plate 23. During drilling, the stabilizing plate 23 is pressed against the outer wall. When all four horizontal rods 231 are completely pressed into the stabilizing plate 23, at this time, the drill bit of the drilling machine 1 is perpendicular to the outer wall.

[0034] Furthermore, one end of the horizontal rod 231 is installed with a restoring spring 2311. A matching groove 2312 is formed on the outer wall of the horizontal rod 231. The restoring spring 2311 can restore the horizontal rod 231 retracted into the stabilizing plate 23. Its matching groove 2312 can contact a matching inclined surface 235, and when the matching inclined surface 235 is completely embedded in the matching groove 2312, the embedding block 2362 can completely disengage from the inserting rod 2241.

[0035] Specifically, four groups of through grooves 232 are provided inside the stabilizing plate 23. A through rod 233 is installed on the inner wall of each group of through grooves 232. A fixing spring 234 is connected to the outer wall of each group of through rods 233. A matching inclined surface 235 is provided at one end of each group of through rods 233. A locking block 236 is installed at one end of each group of through rods 233. The fixing spring 234 applies an elastic force to the through rod 233, so that the matching inclined surface 235 on the through rod 233 presses against the outer wall of the horizontal rod 231. As the horizontal rod 231 moves, its matching inclined surface 235 gradually fits into the matching groove 2312. When it is completely inserted, the horizontal rod 231 also completely retracts into the stabilizing plate 23.

[0036] Further, a support spring 221 is installed inside the sliding rod 22. A support block 222 is installed at one end of the support spring 221. A moving spherical surface 223 is installed on the outer wall of the support block 222. A swinging member 224 is installed on the outer wall of the support block 222. The support spring 221 makes the moving spherical surface 223 on the support block 222 contact the outer wall of the moving block 212. When the sliding rod 22 moves on the slider 21, the moving spherical surface 223 moves under the extrusion of the fixed spherical surface 213.

[0037] Further, the swinging member 224 includes a swinging rod 2242 connected to the outer wall of the support block 222 through a pin shaft. A plug rod 2241 is connected to one end of the swinging rod 2242 through a pin shaft. The plug rod 2241 is a rectangular rod, and grooves matching the embedding block 2362 are provided on the four walls of the rectangular rod. When the matching inclined surface 235 is not completely inserted into the matching groove 2312, the embedding block 2362 still locks the plug rod 2241. When the four horizontal rods 231 are completely inserted into the stabilizing plate 23, that is, when the matching inclined surface 235 is completely inserted into the matching groove 2312, the connection between the plug rod 2241 and the swinging rod 2242 is no longer restricted at this time, so that the moving spherical surface 223 can move when it is extruded by the fixed spherical surface 213, and the sliding rod 22 can slide on the slider 21.

[0038] Further, one end of the plug rod 2241 extends into the inside of the stabilizing plate 23, and when the plug rod 2241 extends, it passes by one side of the through groove 232. The four walls of the plug rod 2241 are perpendicular to the four groups of through rods 233. During drilling, as the drilling depth changes, the sliding rod 22 also moves on the slider 21 accordingly. When the sliding rod 22 moves, the support block 222 moves back and forth on the sliding rod 22 because the moving spherical surface 223 is pressed by the fixed spherical surface 213. The reciprocating movement of the support block 222 drives the plug rod 2241 to reciprocate through the swinging rod 2242. When the plug rod 2241 is locked, the support block 222 cannot move either, so that the sliding rod 22 cannot move on the slider 21.

[0039] Further, one end of each set of locking blocks 236 is equipped with an adaptive spring 2361, and one end of the adaptive spring 2361 is equipped with an embedding block 2362. When the four embedding blocks 2362 are all disengaged from the grooves of the insertion rod 2241, the insertion rod 2241 can resume its movable state. During the drilling process, if the stabilizing plate 23 tilts slightly, one or more of the horizontal rods 231 will be ejected by the restoring spring 2311. At this time, the through rod 233 displaces. If the groove of the insertion rod 2241 during movement does not happen to fit with the embedding block 2362 at this time, the displacement of the through rod 233 presses the adaptive spring 2361, and the adaptive spring 2361 stores energy. When the groove of the insertion rod 2241 moves to the corresponding embedding block 2362, it can be inserted and locked, so as to quickly lock the insertion rod 2241, making the sliding rod 22 unable to move on the slider 21. Furthermore, when the stabilizing plate 23 tilts, the drill bit will no longer continue to penetrate into the outer wall surface.

[0040] Operation process: When drilling, press the stabilizing plate 23 against the outer wall surface, and press the four horizontal rods 231 into the stabilizing plate 23. At this time, the matching grooves 2312 of each horizontal rod 231 are embedded by the matching inclined surfaces 235. At this time, the displacement of the through rod 233 drives the locking block 236 to move, making the embedding block 2362 on the locking block 236 disengage from the insertion rod 2241. Furthermore, none of the four locking rods lock the insertion rod 2241. At this time, the connection between the insertion rod 2241 and the swing rod 2242 is no longer restricted. When the moving spherical surface 223 is squeezed by the fixed spherical surface 213, it can move, making the sliding rod 22 slide on the slider 21. Furthermore, the pressing drilling work can be carried out. If the stabilizing plate 23 tilts slightly, the insertion rod 2241 is quickly locked, making the sliding rod 22 unable to move on the slider 21. Furthermore, when the stabilizing plate 23 tilts, the drill bit will no longer continue to penetrate into the outer wall surface.

[0041] Embodiment 2

[0042] Refer to Figure 5, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: a compression spring 211 is installed on the inner wall of the slider 21, a moving block 212 is installed on one end of the compression spring 211, a fixed spherical surface 213 is installed on the outer wall of the moving block 212, a connecting groove 214 is opened inside the slider 21, a sliding plate 215 is installed on the top of the moving block 212, and a movable second connecting rod 216 is installed on the inner wall of the connecting groove 214 through a pin shaft. When the stabilizing plate 23 tilts slightly, the staff is unaware of it and the pressing force applied by the staff is not cancelled. At this time, the spherical surface 213 is moved. 23 cannot be moved by being touched and pressed, so that the moving spherical surface 223 touches the fixed spherical surface 213 on the moving block 212. At this time, the moving block 212 moves on the compression spring 211. The movement of the moving block 212 drives the sliding plate 215 to move, so that the sliding plate 215 touches the movable second connecting rod 216. The force applied by the compression spring 211 on the moving block 212 is greater than the force of the moving block 212 touching the support block 222, so that when the support block 222 is touched and pressed, the moving block 212 will not be offset, and then when the drilling angle is normal, the force perception of the opening and closing button 11 will not change.

[0043] Specifically, the other end of the movable second link 216 is connected to the inner bottom wall of the opening and closing button 11 through a pin shaft. When the movable second link 216 is bent, the direction of the force applied to the opening and closing button 11 is related to the connection angle of the movable second link 216. The short rod of the movable second link 216 is connected to the inner wall close to the outer side of the opening and closing button 11 through a pin shaft, so that the angle between the short rod and the long rod of the movable second link 216 is less than 90°, so that when the bent second link is rotated by the contact pressure of the sliding plate 215, the force of the bent second link on the opening and closing button 11 is a force in the closing direction. When the opening and closing button 11 is pressed, drilling begins, and the movable second link 216 is deflected, and one end of the movable second link 216 is deflected close to the side of the sliding plate 215.

[0044] The rest of the structure is the same as that of Example 1.

[0045] Operation process: When the stabilizing plate 23 tilts slightly, the staff member does not notice it and the pressing force applied by the staff member is not cancelled. At this time, the moving spherical surface 223 cannot be pressed and moved, so that the moving spherical surface 223 presses the fixed spherical surface 213 on the moving block 212. At this time, the moving block 212 moves on the compression spring 211. The movement of the moving block 212 drives the sliding plate 215 to move, so that the sliding plate 215 presses the movable second connecting rod 216, so that the other end of the movable second connecting rod 216 applies a force to the opening and closing button 11. The force is opposite to the force of the staff member pressing the opening and closing button 11, so that the staff member can sense the change in force and then promptly detect the deviation of the drilling hole, thereby effectively improving the drilling effect.

[0046] Working principle: When drilling, press the stabilizing plate 23 against the outer wall surface, and press all four horizontal rods 231 into the stabilizing plate 23. At this time, the matching grooves 2312 of each horizontal rod 231 are embedded by the matching inclined surfaces 235. At this time, the displacement of the through rod 233 drives the locking block 236 to move, so that the embedding block 2362 on the locking block 236 is disengaged from the insertion rod 2241, and then none of the four locking rods lock the insertion rod 2241. At this time, the connection between the insertion rod 2241 and the swing rod 2242 is no longer restricted. When the moving spherical surface 223 is squeezed by the fixed spherical surface 213, it can move, so that the sliding rod 22 can slide on the slider 21, and then the pressing and drilling work can be carried out. If the stabilizing plate 23 tilts slightly, the insertion rod 2241 is quickly locked, so that the sliding rod 22 cannot move on the slider 21. Then, when the stabilizing plate 23 tilts, one or more of the horizontal rods 231 will be ejected by the restoring spring 2311. At this time, the through rod 233 displaces. If the groove of the moving insertion rod 2241 does not happen to fit with the embedding block 2362 at this time, the displacement of the through rod 233 presses the adaptive spring 2361, and the adaptive spring 2361 stores energy. When the groove of the insertion rod 2241 moves to the corresponding embedding block 2362, it can be inserted and locked, so as to quickly lock the insertion rod 2241, making the sliding rod 22 unable to move on the slider 21. And at this time, when the applied pressing force has not been cancelled, the moving spherical surface 223 cannot be touched and moved, so that the moving spherical surface 223 touches the fixed spherical surface 213 on the moving block 212. At this time, the moving block 212 moves on the pressing spring 211, and the movement of the moving block 212 drives the sliding plate 215 to move, so that the sliding plate 215 touches the movable double-link 216, and the other end of the movable double-link 216 applies a force to the opening and closing button 11. This force is opposite to the force applied by the staff to press the opening and closing button 11, so that the staff can sense the change in force and then detect in time that the drilling has deviated.

[0047] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the embodiments of the present invention.
