Description

Technical Field

[0001] The utility model relates to the technical field of engineering decoration, and specifically, to a drilling device for building decoration. Background Technique

[0002] In building decoration projects, when installing expansion bolts on walls or plates, it is often necessary to drill holes in the wall surface or plate through an electric drill. To ensure that the installed expansion bolts are perpendicular to the wall or plate, it is often necessary to ensure that the drill bit is perpendicular to the wall or plate during the drilling process.

[0003] However, directly using an electric drill to drill holes often causes the drill bit to deviate or not be perpendicular to the wall surface due to reasons such as hand shaking. The national patent CN 219076122 U discloses a drilling device for building engineering, which uses a storage box to ensure that the electric drill is perpendicular to the wall surface or plate. However, in real life, many wall surfaces are often uneven, and the plates may also be deformed due to moisture. In this way, the storage box will tilt when leaning on the wall surface or plate, and still cannot ensure that the drill bit is perpendicular to the wall surface or plate; moreover, a large amount of dust is often generated during the decoration drilling process, causing great pollution to the house environment.

[0004] To address the above problems, there is an urgent need for a drilling device for building decoration. Content of the Utility Model

[0005] The purpose of the utility model is to provide a drilling device for building decoration to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, a drilling device for building decoration is provided, including a bottom plate and a top plate. The bottom plate and the top plate are connected by a telescopic structure. The bottom of the bottom plate is threadedly connected with a threaded adjusting rod, and a suction cup is arranged at the bottom of the threaded adjusting rod. Axial holes are opened on both the bottom plate and the top plate. A vertical correction component for detecting flatness is arranged at the top of the top plate. A telescopic collecting plate is also arranged at the bottom of the bottom plate. A laser emitter is installed at the bottom of the top plate through a universal joint, and the laser emitter can adjust the laser direction through the universal joint so that it points to the direction of the drill bit of the electric drill.

[0007] Further, the telescopic structure includes several telescopic tubes. The diameters of the several telescopic tubes gradually decrease from bottom to top. A compression spring is arranged inside the telescopic tube, and the several telescopic tubes are connected by means of insertion.

[0008] Further, the vertical correction component includes a storage tube, a plumb bob with a conical structure, a wire winding disc, a scale, and a storage groove. The wire winding disc and the storage tube are fixed on the surface of the top plate. A wire hole is provided on the side wall of the storage tube. The plumb line wound on the wire winding disc passes through the wire hole and is connected to the plumb bob. The storage groove is located on the surface of the top plate and is concave. The scale is installed at one end of the storage groove through a pin shaft. The length of the scale is greater than the height of the storage tube, so as to ensure that the plumb line can always contact the scale, and the flatness of the wall surface is judged by the scale where the plumb line is located on the scale.

[0009] Further, the collecting plate is specifically made of corrugated pipe, and the collecting plate has a semi-circular structure. When the ground is used as a reference object, the opening direction of the collecting plate faces upward.

[0010] Further, the central holes opened on the bottom plate and the top plate are coaxially arranged.

[0011] Further, the inner diameter of the storage tube is greater than the diameter of the plumb bob, and a top cover is also installed on the top of the storage tube in a threaded manner. When not in use, the plumb bob can be placed into the storage tube.

[0012] Further, a second spring is also installed in the central hole of the top plate, and a clamping block is arranged at the end of the second spring. Different thicknesses of electric drills can be adapted by the second spring and the clamping block.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. When the electric drill drills a hole, its moving direction is restricted by the telescopic structure and can only move back and forth along the telescopic direction of the telescopic structure. At the same time, with the cooperation of the vertical correction device, it can be ensured that the drill bit penetrates into the wall at an angle perpendicular to the wall surface, thereby ensuring the accuracy of the hole opening;

[0015] 2. The dust generated during drilling can be collected by the collecting plate to prevent the dust from falling on the ground. BRIEF DESCRIPTION OF THE DRAWINGS

It should be further understood that the term "including" used in the specification of the present invention means the presence of the described features, integers, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or their groups.

[0024] Please refer to Figures 1 - 4 As shown, a drilling device for building decoration is provided, including a bottom plate 1 and a top plate 2. The bottom plate 1 and the top plate 2 are connected by a telescopic structure 3. A threaded adjustment rod 4 is threadedly connected to the bottom of the bottom plate 1. A suction cup 5 is provided at the bottom of the threaded adjustment rod 4. Axial holes 9 are opened on both the bottom plate 1 and the top plate 2. The axial holes 9 opened on the bottom plate 1 and the top plate 2 are coaxially arranged. A vertical calibration assembly 6 for detecting flatness is provided at the top of the top plate 2. A telescopic collection plate 7 is also provided at the bottom of the bottom plate 1. The collection plate 7 is specifically made of bellows and has a semi-circular structure. When the ground is used as a reference, the opening direction of the collection plate 7 is upward. The collection plate 7 made of bellows can adjust its length according to the distance between the bottom plate 1 and the wall, which is convenient for collecting the dust generated during drilling. The laser emitter 8 is installed at the bottom of the top plate 2 through a universal joint. The laser emitter 8 can adjust the laser direction through the universal joint so that it points to the drill bit direction, which is convenient for the user to align the place where drilling is required and prevent the drilling position from being misaligned.

[0025] As Figure 3 shown:

[0026] The telescopic structure 3 includes several telescopic tubes 301, the diameters of the several telescopic tubes 301 gradually decrease from bottom to top, a compression spring 302 is arranged inside the telescopic tube 301, and the several telescopic tubes 301 are connected by a plug-in method;

[0027] As Figure 2 shown:

[0028] The vertical correction assembly 6 includes a receiving tube 601, a plumb bob 602 with a conical structure, a winding disc 603, a scale 605 and a receiving groove 606. The winding disc 603 and the receiving tube 601 are fixed on the surface of the top plate 2. A wire hole 604 is provided on the side wall of the receiving tube 601. The plumb line wound on the winding disc 603 passes through the wire hole 604 and is connected to the plumb bob 602. The receiving groove 606 is located on the surface of the top plate 2 and is concave. The scale 605 is installed at one end of the receiving groove 606 through a pin shaft. The length of the scale 605 is greater than the height of the receiving tube 601, so as to ensure that the plumb line can always contact the scale. Whether the wall surface is flat is judged by the scale where the plumb line is located on the scale 605;

[0029] Among them, the inner diameter of the receiving tube 601 is greater than the diameter of the plumb bob 602, and a top cover is also installed on the top of the receiving tube 601 in a threaded manner. When not in use, the plumb bob 602 can be placed into the receiving tube 601;

[0030] It should be noted that, as Figure 4 shown: When the device is adsorbed on the surface of the wall or an object to be drilled through a suction cup, the position of the scale 605 is directly below the receiving groove 606. Here, wall opening is taken as an example.

[0031] To increase the adaptability of the device, a second spring 10 is also installed in the central hole 9 of the top plate 2, and a clamping block 11 is arranged at the end of the second spring 10. Different thicknesses of electric drills can be adapted through the second spring 10 and the clamping block 11.

[0032] Working process:

[0033] Place the device on the wall, move the device so that the laser emitted by the laser emitter 8 coincides with the marked drilling point, rotate the scale 605 to a position perpendicular to the top plate 2, then take out the plumb bob 602 and let it fall naturally. Whether the wall surface is flat is judged according to the scale at the position where the plumb line contacts the scale 605. Since the height of the receiving tube 601 is fixed, the position of the contact point between the plumb line and the receiving tube 601 will not change. Subtract the height of the receiving tube 601 from the scale where the plumb line is located to judge whether the wall surface is flat, and then adjust the length of the threaded adjustment rod 4 according to the corresponding difference in scale;

[0034] After leveling, use the suction cup 5 to adsorb the device on the wall surface, then pull out the collection plate 7 so that its end abuts against the wall surface, and finally insert the electric drill into the axial hole 9 to perform the drilling operation.

[0035] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
