Description

Technical Field

[0001] The utility model relates to the technical field of wall construction, in particular to a wall punching device for preventing fly ash. Background Art

[0002] When renovating a house, it is often necessary to drill holes in the concrete wall to facilitate the installation of various pipes, lines, etc. At present, when holes need to be drilled in the wall, the construction workers use a handheld drilling machine to drill directly on the wall. When the drill bit drills holes in the wall, a large amount of dust will be generated. The dust will splash everywhere and may even splash onto the face of the construction workers, which not only affects eye health, but may also be inhaled into the human body, causing more serious dust diseases. Moreover, the dust generated by drilling is difficult to clean, which increases the difficulty of subsequent house cleaning. At the same time, the existing drilling machines cannot control the drilling depth well. The depth of the hole is controlled according to the experience of the construction workers, which will cause the accuracy of the hole in the wall to be very poor, affecting the subsequent installation of expansion bolts and other components. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a wall punching device for preventing fly ash, which can effectively prevent dust from splashing and control the punching depth to ensure the construction quality.

[0005] On the basis of the above scheme and as a preferred scheme of the above scheme: the first sleeve and the second sleeve are made of transparent material, and a plurality of colored marking lines are provided on the outer circumference of the second sleeve, and the marking lines correspond to the scale values ​​on the scale lines.

[0006] On the basis of the above scheme and as a preferred scheme of the above scheme: when the slider at the front end of the second sleeve abuts against the rear groove wall of the first sleeve slide groove, the edge of the first sleeve coincides with the O reference line of the scale line on the second sleeve.

[0007] On the basis of the above scheme and as a preferred scheme of the above scheme: the lower end of the ash guide hopper is provided with a connecting port, the connecting port is provided with an external thread structure, and the ash collecting bottle and the ash guide hopper are fixed by threaded connection.

[0008] On the basis of the above scheme and as a preferred scheme of the above scheme: the screw hole set at the rear end of the second sleeve cooperates with the fastening bolt, and the second sleeve is fixed to the front end of the drilling machine and tightly attached to the front end of the drilling machine.

[0009] On the basis of the above scheme and as a preferred scheme of the above scheme: a ring-shaped guide surface is extended outward from the front end of the first sleeve, and the guide surface is perpendicular to the axial direction of the first sleeve.

[0010] When using:

[0011] 1) Assemble the first sleeve and the second sleeve and adjust the length. At this time, the first sleeve and the second sleeve are in the longest state, that is, the rear edge of the first sleeve is aligned with the O point of the scale line on the second sleeve, and then rotate the ash collecting bottle under the ash guide hopper;

[0012] 2) Put the second sleeve on the front end of the drilling machine and fix it with a locking screw. At this time, the front end of the drill bit is flush with the front edge of the first sleeve, that is, the first sleeve is in contact with the wall surface, and the drill bit is also against the wall surface;

[0013] 3) Aim the drill bit at the part where the hole needs to be drilled, and the first sleeve fits against the wall;

[0014] 4) Start the drilling machine, the drill bit starts drilling, moves toward the wall, and also pushes the second sleeve toward the first sleeve. At this time, the position reading of the rear edge of the first sleeve on the scale line of the second sleeve is the depth of the drill bit drilling;

[0015] 5) The ash generated by drilling with the drill bit splashes in the first sleeve and eventually falls from the ash guide hopper into the ash collecting bottle;

[0016] 6) When the reading of the rear edge of the first sleeve on the scale line of the second sleeve is obtained, the drilling machine stops working;

[0017] 7) After drilling multiple times, you can unscrew the ash collecting bottle, clean out the dust in the bottle, and then continue working.

[0019] 1. A first sleeve and a second sleeve are provided at the front end of the drilling machine. The first sleeve can cover the periphery of the wall drilling area, so that all the dust generated by drilling is concentrated in the first sleeve and the second sleeve, and most of the dust falls from the dust guide hopper into the dust collection bottle, which is convenient for cleaning dust;

[0020] 2. There are scale lines on the outside of the second sleeve. During the drilling process, the rear edge of the first sleeve can move on the scale lines to show the depth of the drilling and ensure the accuracy of the drilling;

[0021] 3. The first sleeve and the second sleeve are made of transparent material, which is convenient for aligning the drill bit with the drilling position. At the same time, colored marking lines are marked on the scale lines, which is convenient for users to quickly read the scales and improve the drilling efficiency and accuracy;

[0022] 4. A guide surface is provided at the front end of the first sleeve. After the guide surface is in contact with the wall, the first sleeve and the second sleeve are perpendicular to the wall, so that the second sleeve moves vertically to the wall relative to the first sleeve, thereby ensuring the verticality of the punching.
