Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a drilling bit for punching holes in a building wall. Background Art

[0002] Building drilling refers to the detailed plan and program for drilling holes in building walls. Punching is a common operation in construction. It is mainly used to install pipes, wires, ventilation ducts, etc., to achieve functions while ensuring the safety of the building structure.

[0003] In the prior art, the ring body is mainly attached to the surface of the wall side wall so that the drill bit can be perpendicular to the wall side wall. However, in the actual drilling operation, the wall side wall is not necessarily vertical and there may be some deviations, which results in the hole being not a vertical hole. Therefore, it is necessary to design a building wall drilling drill bit to solve this problem. Utility Model Content

[0004] The utility model aims to provide a drilling bit for drilling holes in building walls, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A drilling bit for punching holes in a building wall comprises an annular plate, one side of the annular plate is fixedly connected to two symmetrical fixing rods, the two fixing rods are fixedly connected together to an annular frame located on the same central axis as the annular plate on the side away from the annular plate, two symmetrical rotating shafts are rotatably plugged into the annular frame via bearings, an annular block located in the annular frame is fixedly connected between the two rotating shafts, a drill rod is inserted into the annular block, and a limiting piece for fixing the position of the rotating shaft is arranged on the annular frame.

[0007] Preferably, the limiting member includes a columnar block fixedly connected to one side of one of the rotating shafts, a row of limiting grooves are provided on the top of the columnar block along its circumference, a connecting block in contact with the top of the columnar block is provided on the annular frame, and a limiting block inserted into one of the limiting grooves is formed at the bottom of the connecting block, and a spring for pushing the connecting block to always move in the direction of the columnar block is also provided on the annular frame, so that the columnar block can be limited and fixed, thereby achieving the purpose of fixing the rotating shaft to prevent it from rotating.

[0008] Preferably, a fixed block in an inverted L-shaped structure is fixedly connected to one side of the top of the annular frame, a connecting rod is inserted through the top of the fixed block, the bottom of the connecting rod is fixed to the top of the connecting block, and a spring is sleeved on the connecting rod and located between the connecting block and the fixed block, so that the spring can always push the connecting block to contact the surface of the columnar block through its own elastic action.

[0009] Preferably, two symmetrical cones are fixedly connected to one side of the annular plate away from the fixing rod, so that when the annular plate contacts the side wall inside the wall, the two cones can be inserted into the inner wall.

[0010] Preferably, a thread is provided on one side of the drill rod away from the annular plate along its length direction, and a limiting sleeve is sleeved on the drill rod through threaded engagement, and the limiting sleeve can be moved forward and backward on the drill rod through threaded engagement by rotating the limiting sleeve.

[0011] Preferably, the inner diameter of the annular plate is at least 3 / 1 of the diameter of the drill rod, so that there is enough space for the drill rod to adjust the angle.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model can place the annular plate on the side wall in the wall, and then use a level ruler or other measuring tools to measure whether the drill rod is in a vertical state with the side wall at this time. If there is a deviation, the annular block can be rotated up and down in the annular frame to fine-tune the drilling angle of the drill rod. After the annular block is rotated to a suitable position, the rotating shaft can be fixed by a limiter to fix the position of the annular block, thereby ensuring the verticality of the drill rod drilling process.

[0014] 2. The utility model can rotate the limit sleeve to make it move forward and backward on the drill rod through threaded cooperation to change its position. When drilling, the drill rod will also drive the limit sleeve to move and abut against the surface of the annular block, so that the travel of the drill rod can be limited to enable hole processing of different depths.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] Obviously, many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] See also Figure 1-4 The utility model provides a drilling bit for drilling holes in a building wall: it comprises an annular plate 1, one side of the annular plate 1 is fixedly connected with two symmetrical fixing rods 2, and the two fixing rods 2 are fixedly connected with an annular frame 3 located on the same central axis as the annular plate 1 on one side away from the annular plate 1, and two symmetrical rotating shafts 4 are rotatably inserted and plugged on the annular frame 3 through bearings, and an annular block 5 located in the annular frame 3 is fixedly connected between the two rotating shafts 4, and a drill rod 6 is inserted and connected in the annular block 5, and a limiting piece for fixing the position of the rotating shaft 4 is arranged on the annular frame 3. Through such a design, the annular plate 1 can be placed on the side wall in the wall, and then a measuring tool such as a level ruler can be used to measure whether the drill rod 6 is in a vertical state with the side wall at this time. If there is a deviation, the annular block 5 can be rotated up and down in the annular frame 3 to fine-tune the drilling angle of the drill rod 6. After the annular block 5 is rotated to a suitable position, the rotating shaft 4 is fixed by the limiting piece, so that the position of the annular block 5 can be fixed, and the verticality of the drilling processing of the drill rod 6 can be ensured.

[0023] Specifically, in order to fix the position of the rotating shaft 4, in some embodiments, it is proposed that the limiting member includes a columnar block 7 fixedly connected to one side of the rotating shaft 4, and a row of limiting grooves 8 are provided on the top of the columnar block 7 along its circumference. A connecting block 9 in contact with the top of the columnar block 7 is provided on the annular frame 3, and a limiting block 10 inserted into one of the limiting grooves 8 is formed at the bottom of the connecting block 9. The annular frame 3 is also provided with a spring 11 for pushing the connecting block 9 to always move in the direction of the columnar block 7, so that the columnar block 7 can be limited and fixed, thereby achieving the purpose of fixing the rotating shaft 4 to prevent it from rotating. When the annular block 5 needs to be rotated, the connecting block 9 can be pushed upward to pull the limiting block 10 out of the limiting groove 8. At this time, the rotating shaft 4 can be rotated and the drilling angle of the drill rod 6 can be changed.

[0024] Furthermore, a fixed block 12 in an inverted L-shaped structure is fixedly connected to one side of the top of the annular frame 3, a connecting rod 13 is inserted through the top of the fixed block 12, the bottom of the connecting rod 13 is fixed to the top of the connecting block 9, and the spring 11 is sleeved on the connecting rod 13 and is located between the connecting block 9 and the fixed block 12, so that the spring 11 can always push the connecting block 9 to contact the surface of the columnar block 7 through its own elastic action.

[0025] In addition, two symmetrical cones 14 are fixedly connected to the side of the annular plate 1 away from the fixing rod 2, so that when the annular plate 1 contacts the side wall inside the wall, the two cones 14 can be inserted into the inner wall to fix the annular plate 1 in the wall, thereby facilitating subsequent drilling operations.

[0026] It should be noted that a thread is provided along the length direction of the drill rod 6 on the side away from the annular plate 1, and a limiting sleeve 15 is sleeved on the drill rod 6 through a threaded fit. By rotating the limiting sleeve 15, it can be moved back and forth on the drill rod 6 through a threaded fit to change its position. When drilling, the drill rod 6 will also drive the limiting sleeve 15 to move and abut against the surface of the annular block 5. In this way, the travel of the drill rod 6 can be limited so that holes of different depths can be processed.

[0027] At the same time, the inner diameter of the annular plate 1 is at least 3 / 1 of the diameter of the drill rod 6, so that the drill rod 6 has enough space to adjust the angle. Such a design will be more reasonable.
