[0001] The invention relates to building construction technology, and in particular to a building exterior wall punching device for construction engineering. Background Art

[0002] During the construction process, it is often necessary to drill holes in the exterior walls of buildings to facilitate the installation of exterior wall frames or other brackets, curtain walls and other components.

[0003] The electric drill is a commonly used instrument in the process of drilling holes in exterior walls. During the drilling process, due to the large weight of the electric drill itself, the burden on the operator is small when drilling holes at a position relatively low relative to the height of the operator. However, when drilling holes at a relatively high position, the operator not only needs to raise his arms to lift the drill, but also needs to apply pressure to the electric drill on the side close to the wall. Therefore, the burden on the operator is large, and it is not only difficult to ensure the accuracy of the drilling position, but also easy to cause the drilling to be skewed, which makes the drilling efficiency of the exterior wall not only low, but also its accuracy cannot meet the actual construction needs.

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Embodiment 1: See also Figure 1-Figure 9 , a device for punching holes on the outer wall of a building for construction engineering, comprising an electric drill body 1, a drill bit 101 is arranged at one end of the electric drill body 1, a fixed sleeve 2 is arranged at the end of the electric drill body 1 close to the drill bit 101, a movable sleeve 21 is slidably connected to the inner side of the fixed sleeve 2, a supporting spring 22 is arranged between the movable sleeve 21 and the fixed sleeve 2, a square support plate 23 is fixedly connected to the end of the movable sleeve 21, a receiving groove 24 is opened on the bottom side of the surface of the square support plate 23, an extension block 25 is slidably connected to the inner side of the receiving groove 24, and the extension block 25 is flush with the surface of the square support plate 23 away from the electric drill body 1. Through the setting of the extension block 25, the square support plate 23 can effectively increase the support range of the square support plate 23 during the process of supporting the drill bit 101 by the square support plate 23, so that when the operator controls the drill bit 101 to move for deep hole drilling, it is not easy to tilt, thereby effectively ensuring the accuracy of drilling.

[0022] It should be added that a non-through straight groove is provided on the inner wall of the accommodating groove 24, and a connecting block that can slide along the inner wall of the non-through straight groove is provided on the side of the extension block 25, so that the extension block 25 can slide smoothly along the inner wall of the accommodating groove 24 without withdrawing from the inside of the accommodating groove 24. In addition, the surface of the connecting block is roughened, so that there is a certain sliding friction resistance when the connecting block slides along the inner wall of the non-through straight groove, so that the support stability of the extension block 25 is better during the support process.

[0023] In this embodiment, the inner side surface of the fixed sleeve 2 is annular and has multiple groups of guide grooves 26 equidistantly provided thereon. The inner side surface of the guide groove 26 is slidably connected with a guide block 27, which is connected to the movable sleeve 21. The support spring 22 is fixedly connected between the inner wall of the guide groove 26, close to the electric drill body 1, and the guide block 27.

[0024] In this embodiment, a transparent portion 28 is provided on the movable sleeve 21 near the square support plate 23. The transparent portion 28 can facilitate accurate positioning of the drill bit 101 during drilling, thereby ensuring the accuracy of drilling holes on the exterior wall.

[0025] In this embodiment, the surface of the extension block 25 and the surface of the square support plate 23 are both provided with an embedding groove 29, and an anti-slip rubber pad 210 is embedded inside the embedding groove 29. The surface of the anti-slip rubber pad 210 is flush with the surface of the extension block 25. Through the provision of the anti-slip rubber pad 210, the contact friction resistance between the square support plate 23 and the extension block 25 and the outer wall surface can be effectively increased, so that during the drilling process, the drill bit 101 is not easy to be displaced.

[0026] When drilling holes in the exterior wall, the operator pulls the extension block 25 outward to move it outward to the extreme position, and then aligns the drill bit 101 with the position of the exterior wall where the hole needs to be drilled, and then starts the electric drill body 1 to drill. During the drilling process, the operator applies a force perpendicular to the exterior wall to the electric drill body 1, so that the electric drill body 1 moves closer to the exterior wall for drilling. During this process, with the support of the square support plate 23 and the extension block 25, the drill bit 101 is not easily deflected, thereby ensuring the accuracy of the exterior wall drilling.

[0027] An embedding slot 3 is provided on the top of the electric drill body 1 away from the drill bit 101, and a connecting plate 31 is embedded in the inner side of the embedding slot 3. The outer surface of the connecting plate 31 is roughened, and an extension plate 32 is slidably connected to the surface of the connecting plate 31. The surface of the extension plate 32 is slidably connected to a support plate 33, and a top plate 310 is fixedly installed on the bottom of the support plate 33.

[0028] In this embodiment, a ⊥-shaped slider 34 is installed on the bottom surface of the connecting plate 31 and the bottom surface of the extending plate 32 near one end of the supporting plate 33, a sliding groove 35 corresponding to the ⊥-shaped slider 34 is provided on the surface of the extending plate 32 and the surface of the supporting plate 33, a buffer groove 36 is provided on the surface of the extending plate 32 and the surface of the supporting plate 33, a buffer spring 37 is fixedly connected to the inner side of the buffer groove 36, and a limiting block 38 is fixedly connected to the end of the buffer spring 37, and a slot 39 corresponding to the two limiting blocks 38 is provided on the surface of the connecting plate 31 and the extending plate 32 respectively, and when the limiting block 38 moves to the inside of the sliding groove 35 near one end of the limiting block 38, the position of the slot 39 corresponds to the buffer groove 36.

[0029] When drilling holes at low places without requiring the operator to raise his arm to drill holes on the outer wall, the connection plate 31 does not need to be installed. When the operator needs to raise his arm to drill holes, the operator inserts the connection plate 31 into the embedding slot 3 on the electric drill body 1, and then pulls the extension plate 32 and the support plate 33 to the side away from the connection plate 31, so that the limiting block 38 on the support plate 33 can fall into the slot 39 on the extension plate 32, and the limiting block 38 on the extension plate 32 can fall into the slot 39 on the connection plate 31, so that the connection between the connection plate 31, the extension plate 32 and the support plate 33 can be more stable under the cooperation between the slot 39 and the limiting block 38, and relative movement is not easy to occur; During the drilling process, the operator supports the support plate 33 on his shoulders so that the top plate 310 is located on the chest side, which not only provides a stable support for the electric drill body 1, but also effectively reduces the burden on the operator when raising his arms to drill, making the drilling efficiency of the exterior wall higher; When it is necessary to fold up the connecting plate 31, the extension plate 32 and the support plate 33, the operator presses the limiting block 38 through the slot 39 to move it out of the slot 39 and into the buffer slot 36, so that it no longer restricts the relative movement between the connecting plate 31 and the extension plate 32 and the relative movement between the extension plate 32 and the support plate 33, so that they can be folded.

[0030] Embodiment 2: See also Figure 4 This embodiment provides a technical solution based on the above embodiment: an external threaded joint 211 is installed at one end of the electric drill body 1 close to the drill bit 101, and the fixed sleeve 2 is threadedly connected to the external threaded joint 211. A supporting ring groove 212 corresponding to the fixed sleeve 2 is opened on the end surface of the electric drill body 1. When the fixed sleeve 2 is threadedly connected to the external threaded joint 211, the end of the fixed sleeve 2 is embedded in the supporting ring groove 212.

[0031] During use, when the drill bit 101 needs to be replaced, the operator can rotate the fixed sleeve 2 to separate it from the external threaded joint 211, thereby facilitating the replacement of the drill bit 101. In addition, with the cooperation of the support ring groove 212, the force burden of the external threaded joint 211 can be reduced during the drilling process, thereby effectively ensuring the support stability of the fixed sleeve 2.

[0032] Embodiment 3: See also Figure 8-Figure 9 The present embodiment provides a technical solution based on the above-mentioned embodiment: a dust outlet groove 4 is provided on the side of the transparent portion 28, an external threaded connecting pipe 41 is provided on the outside of the dust outlet groove 4, a sleeve 42 is connected to the external thread of the external threaded connecting pipe 41, the bottom of the sleeve 42 is through-set, and a dust suction fan 43 is installed at the bottom of the sleeve 42, a support ring 44 is provided on the inner wall of the sleeve 42, a dust collecting box 45 is placed inside the sleeve 42, a positioning tube 46 connected to the bottom of the sleeve 42 is fixedly installed at the bottom of the inner wall of the dust collecting box 45, a dust filter element 47 is sleeved on the positioning tube 46, an air groove 410 is provided in the middle of the dust collecting filter element 47, a pressing frame 48 is provided between the dust collecting box 45 and the external threaded connecting pipe 41, and a closed pressing plug 49 corresponding to the air groove 410 is provided at the bottom of the pressing frame 48.

[0033] It should be noted that the shapes and dimensions of the positioning tube 46 and the closing plug 49 are compatible with the air outlet groove 410 . When the sleeve 42 is threadedly connected to the external threaded connecting tube 41 , the clamping frame 48 abuts between the dust collecting box 45 and the external threaded connecting tube 41 .

[0034] In addition, the inner side surface of the fixed sleeve 2 is slidably connected with the connecting ring 5, the guide block 27 is fixedly connected to the outer side surface of the connecting ring 5, the end of the movable sleeve 21 is rotatably connected to the connecting ring 5, and the movable sleeve 21 and the connecting ring 5 are coaxially arranged, so that the movable sleeve 21 and the fixed sleeve 2 can rotate relative to each other, so that the sleeve 42 can always be at the bottom end of the transparent part 28 during the drilling process, which can effectively ensure the smooth progress of the dust cleaning work.

[0035] During the drilling process, the dust suction fan 43 is started to generate suction at the dust outlet slot 4, and the generated dust is pulled so that it passes through the dust outlet slot 4 and enters the dust collecting box 45, and the incoming air flow passes through the outside of the dust filter element 47 and enters the internal air flow slot 410 thereof, and finally flows downward from the positioning tube 46 to the bottom of the sleeve 42 and is discharged from the bottom thereof, and the incoming dust is filtered and collected in the dust collecting box 45; During subsequent cleaning, the operator rotates the sleeve 42 to separate the sleeve 42 from the external threaded connecting tube 41. At this time, the operator removes the clamping frame 48, and then removes the dust box 45 from the sleeve 42, and then removes the filter element from the dust box 45 for replacement, and pours out the dust in the dust box 45 to complete the dust cleaning.

[0036] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
