Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a positioning device for drilling holes in building walls. Background Art

[0002] During the renovation process, it is usually necessary to install central air conditioning or carry out water and electricity pipe routing indoors. When performing these operations, it is usually necessary to use an electric drill in conjunction with a drilling and positioning mechanism to drill holes in the indoor walls in advance, thereby facilitating the installation of central air conditioning and other equipment.

[0003] Some existing drilling positioning mechanisms are mainly composed of a fixing part, an inner cylinder, an outer cylinder and a suction cup. When in use, the inner cylinder is aligned with the position to be drilled, and then the fixing part is pressed to make the suction cup adsorb on the wall. Then, the drill bit of the electric drill is inserted into the inner cylinder and starts to drill holes in the wall. In this process, due to unstable manual grip or the reaction force received by the drill bit when drilling is offset by the suction cup, the hole drilled in the wall is parallel to the ground. Through the above actions, the drilling operation is completed.

[0004] However, in the above process, most of the indoor walls that need to install central air conditioning or carry out water and electricity pipe routing operations are rough surfaces, which makes it easy for the suction cup to be unstable during adsorption, and the force generated during drilling can easily drive the suction cup away from the wall, thereby affecting the quality of the drilling. Summary of the invention

[0007] Furthermore, a slot is provided in the wall of the outer cylinder, the opening of the slot faces the inner cylinder, an insertion rod is sealingly and slidably installed inside the slot, the insertion rod extends out of the slot at one end facing the inner cylinder and is fixedly connected to the inner cylinder, and an air outlet is provided inside the outer cylinder and at the end of the slot facing away from the opening, and the air outlet connects the external environment and the slot.

[0008] Furthermore, a collecting box is fixedly mounted on a side of the outer cylinder facing away from the fixing member, and the cavity of the collecting box is communicated with the inner cavity of the outer cylinder.

[0009] Furthermore, a swivel is slidably installed in the inner cavity of the outer cylinder and at a position on the side of the inner cylinder facing the collection box. The swivel forms a sealed sliding connection with the inner cylinder. A contact mechanism and a control mechanism are arranged inside the swivel. The contact mechanism is controlled by the control mechanism to be pressed against the drill bit surface of the electric drill.

[0010] Furthermore, the contact mechanism includes an annular groove, an airbag, a telescopic groove, a telescopic member and a contact wheel. An annular groove is opened on the outer side of the rotating ring, an airbag is arranged in the annular groove, the outer side of the airbag is fixedly connected to the outer inner wall of the annular groove, telescopic grooves are opened equidistantly in the circumference of the rotating ring and located on the inner side of the annular groove, the outer side of the telescopic groove is communicated with the annular groove, the inner side of the telescopic groove is opened on the inner side surface of the rotating ring, a telescopic member is slidably installed inside the telescopic groove, a contact wheel is rotatably installed on the inner side of the telescopic member, the upper side of the telescopic member extends into the annular groove and is fixedly connected to the inner side surface of the airbag.

[0011] Further, the control mechanism includes a No. 1 air guide hole, a No. 2 air guide hole, a pressure groove, and an air pressure piece. The No. 1 air guide hole is opened inside the rotating ring and located at the outer side of the ring groove. The No. 2 air guide hole is fixedly installed in the wall of the inner cylinder. The pressure groove is opened inside the inner cylinder and at a position away from the side of the rotating ring. One side of the No. 1 air guide hole is connected with the air bag, the other side of the No. 1 air guide hole is connected with one side of the No. 2 air guide hole, and the other side of the No. 2 air guide hole is connected with the pressure groove.

[0012] Furthermore, scrapers are fixedly installed at equal intervals in the circumferential direction on the side of the swivel facing away from the inner tube.

[0014] Through the setting of the inner cylinder, outer cylinder and collection box, when the drill bit passes through the inner cylinder and penetrates into the wall, the dust generated by the drill bit will be blocked by the outer cylinder and the inner cylinder, and then under its own weight, accumulate downward into the collection box. Through this action, the probability of dust escaping to the external environment is reduced, thereby improving the safety of the drilling environment.

[0015] By setting the contact wheel, the rotating ring and the inner cylinder, the contact wheel is pressed against the outside of the drill bit's rod body. Afterwards, when the drill bit penetrates into the wall, the inner cylinder and the rotating ring are driven close to the wall, and the rotating ring rotates. At the same time, the rotating ring scrapes the dust on the inner wall of the outer cylinder and pushes the dust into the collection box. Through this action, the probability of dust escaping to the external environment is further reduced. In addition, since the contact wheel contacts the drill bit's rod body and is driven to rotate by the drill bit, the probability of dust escaping to the external environment through the gap between the rotating ring and the drill bit is further reduced.

[0016] Through the setting of the rotating ring and the scraper, during the rotation of the above-mentioned rotating ring, the scraper will be driven to rotate synchronously, thereby forming a rotating airflow in the inner cavity of the outer cylinder, causing the dust particles moved to the airflow position to be thrown outward and then moved to the collection box. Through this action, the probability of dust escaping to the external environment is reduced, thereby improving the safety of the drilling environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] Example 1: Please refer to Figure 1-Figure 7 , a building wall punching positioning device comprises a mounting seat 1, a slide groove 2 is opened inside the mounting seat 1, a screw rod 3 is arranged inside the slide groove 2, two ends of the screw rod 3 are rotatably connected with the inner wall of the corresponding direction of the slide groove 2, a slider 4 is slidably installed in the slide groove 2, the slider 4 and the screw rod 3 form a threaded transmission connection, a turntable 5 is fixedly installed at one end of the screw 3, a support rod 6 is arranged inside the mounting seat 1 and at a position on one side of the slide groove 2 (the support rod 6 and the mounting seat 1 together constitute a combination of an electric control telescopic cylinder and an output rod in the prior art), the number of the support rods 6 is two, and the two support rods 6 extend from the two ends of the mounting seat 1 respectively, a fixing piece 7 is fixedly installed on the side of the slider 4 facing away from the support rod 6, an outer cylinder 8 is fixedly installed on the side of the fixing piece 7 facing away from the slider 4, an inner cylinder 9 is slidably installed inside the outer cylinder 8, the drill bit of the electric drill passes through the inner cylinder 9 to contact the wall, and there is a distance in millimeters between the drill bit of the electric drill and the inner wall of the inner cylinder 9.

[0022] When in use, firstly, the mounting base 1 is made to fit in contact with the wall to be punched, then the support rod 6 is extended and abuts against the wall in the corresponding direction of the support rod 6 (or abuts against the ceiling and the ground), and then the fixing member 7, the outer cylinder 8 and the inner cylinder 9 are fixed at corresponding positions by pressure. At this time, the outer cylinder 8 and the fixing member 7 fit in contact with the wall to be punched. Through this action, the stability between the positioning mechanism and the wall is increased, and the influence of the loose fixation of the positioning mechanism on the drilling quality is reduced. Then, the turntable 5 is rotated so that the screw rod 3 drives the fixing member 7, the outer cylinder 8 and the inner cylinder 9 to move to the position to be punched, and then the drill bit of the electric drill is extended out of the inner cylinder 9 and contacts the wall, so that the drill bit gradually drills into the wall. In this process, the grip body of the electric drill contacts the inner cylinder 9 and pushes the inner cylinder 9 to gradually extend into the outer cylinder 8. When the reaction force of the drill bit when drilling is transmitted to the inner cylinder 9 due to unstable manual grip or the reaction force of the drill bit when drilling, the inner cylinder 9 will block the above force, thereby preventing the drill bit from drilling deflection.

[0023] See also Figure 1-Figure 7 A slot 10 is provided in the wall of the outer tube 8, and the opening of the slot 10 faces the inner tube 9. An insertion rod 11 is installed in the slot 10 in a sealing and sliding manner. The insertion rod 11 extends out of the slot 10 at one end facing the inner tube 9 and is fixedly connected to the inner tube 9. An air outlet 12 is provided inside the outer tube 8 and at the end of the slot 10 facing away from the opening. The air outlet 12 connects the external environment with the slot 10.

[0024] When the holding body of the electric drill pushes the inner cylinder 9 to gradually extend into the outer cylinder 8, the inner cylinder 9 will drive the insertion rod 11 to gradually extend into the slot 10 and squeeze the air in the slot 10 out of the air outlet 12. Through this action, when the inner cylinder 9 gradually extends into the outer cylinder 8, it will not be subjected to further increased restoring force, thereby saving effort for the staff.

[0025] Example 2: Please refer to Figure 1-Figure 7 This embodiment is a further improvement of the first embodiment, and the improvement lies in that a collecting box 13 is fixedly mounted on the side of the outer tube 8 facing away from the fixing member 7 , and the cavity of the collecting box 13 is connected to the inner cavity of the outer tube 8 .

[0026] In the process of the drill bit passing through the inner cylinder 9 and drilling into the wall, the dust generated by the drill bit will be blocked by the outer cylinder 8 and the inner cylinder 9, and then it will be under its own weight and accumulate downward into the collection box 13. Through this action, the probability of dust escaping to the external environment is reduced, thereby improving the safety of the drilling environment.

[0027] See also Figure 1-Figure 7A swivel 14 is slidably installed in the inner cavity of the outer cylinder 8 and located at the position of the inner cylinder 9 facing the collecting box 13. The swivel 14 forms a sealed sliding connection with the inner cylinder 9. An annular groove 15 is provided at the outer side of the swivel 14. An airbag 16 is arranged in the annular groove 15. The outer side of the airbag 16 is fixedly connected to the outer inner wall of the annular groove 15. Telescopic grooves 17 are equidistantly provided in the circumferential direction at the inner side of the swivel 14 and located at the inner side of the annular groove 15. The outer side of the telescopic groove 17 is communicated with the annular groove 15. The inner side of the telescopic groove 17 is provided on the inner side surface of the swivel 14. A telescopic member 18 is slidably installed in the telescopic groove 17. A contact wheel 19 is rotatably installed on the inner side of the telescopic member 18. The upper side of the telescopic member 18 extends into the annular groove 15 and forms a fixed connection with the inner side surface of the airbag 16. The inner side of the swivel 14 and located at the annular groove A No. 1 air guide hole 20 is provided at the outer position of 15, a No. 2 air guide hole 21 is fixedly installed in the wall of the inner tube 9, a pressure groove 22 is provided inside the inner tube 9 and at a position facing away from the side of the swivel 14, one side of the No. 1 air guide hole 20 is communicated with the air bag 16, the other side of the No. 1 air guide hole 20 is communicated with one side of the No. 2 air guide hole 21, the other side of the No. 2 air guide hole 21 is communicated with the pressure groove 22, and the pressure groove 22 is provided with a gas pressure piece 23, which is divided into a rough section, a threaded section and a sealing section from top to bottom, the rough section extends out of the pressure groove 22, the threaded section is threadedly connected to the inner wall corresponding to the pressure groove 22, the sealing section is sealed and slidably connected to the inner wall of the pressure groove 22, and the cavity in the pressure groove 22 at the lower side of the sealing section, the No. 2 air guide hole 21 and the No. 1 air guide hole 20 are all filled with air.

[0028] In the process of the drill bit passing through the inner cylinder 9, the drill bit will synchronously pass through the swivel 14. Later, when the drill bit contacts the wall, the staff twists the rough section of the air compressor 23 to make the air compressor 23 further extend into the pressure groove 22, so that the sealing section of the air compressor 23 presses the air in the pressure groove 22 into the No. 2 air guide hole 21, so that the air in the No. 2 air guide hole 21 is transmitted to the air bag 16 through the No. 1 air guide hole 20, so that the air bag 16 expands and drives the telescopic member 18 and the contact wheel 19 to move inward, so that the contact wheel 19 is pressed tightly against the outside of the rod body of the drill bit. Through this action, the synchronous inward movement of the inner cylinder 9 can be achieved without the need to use the grip body of the electric drill to contact, so that the length of the drill bit limited by the inner cylinder 9 is shortened, so that the drill bit can be extended into the wall for a longer distance, thereby improving the scope of application of the device. Later, when drilling, In the process of the drill bit penetrating into the wall, the inner cylinder 9 and the swivel ring 14 will be driven close to the wall, and the swivel ring 14 will rotate. At the same time, the swivel ring 14 will rotate to scrape the dust on the inner wall of the outer cylinder 8 and push the dust into the collection box 13. Through this action, the probability of dust escaping to the external environment is further reduced. In addition, since the contact wheel 19 contacts the rod body of the drill bit and is driven to rotate by the drill bit, the dust will be blocked to a certain extent when passing through the gap between the swivel ring 14 and the drill bit, so that the probability of dust escaping to the external environment is further reduced. In addition, since the contact wheel 19 is a wheel-shaped structure, when the drill bit drives the swivel ring 14 and the inner cylinder 9 to extend into the outer cylinder 8 to the limit, the drill bit can continue to penetrate into the wall, prompting the drill bit that penetrates into the wall to rotate through the friction and pressure between the contact wheel 19 and the drill bit.

[0029] See also Figure 1-Figure 7 The side of the swivel 14 facing away from the inner tube 9 is equidistantly fixed with scrapers 24 circumferentially. When the swivel 14 is extended into the outer tube 8 to the limit, the length of the scrapers 24 is less than the distance between the swivel 14 and the wall.

[0030] During the rotation of the above-mentioned rotating ring 14, the scraper 24 will be driven to rotate synchronously, thereby forming a rotating airflow in the inner cavity of the outer cylinder 8, causing the dust particles moved to the airflow position to be thrown outward and then move into the collection box 13 (the inner cavity of the collection box 13 can be set longer, so that the dust falling into the collection box 13 is not easily attracted by the rotating scraper 24). Through this action, the probability of dust escaping to the external environment is reduced, thereby improving the safety of the drilling environment.
