A non-combustible board water and electricity installation hole opening device

Abstract

This application relates to a hole-making device for non-combustible boards used for plumbing and electrical installations, and pertains to the field of non-combustible board hole making. The device includes an electric drill with a hole saw mounted on its output end. A circular tube is fitted onto the surface of the drill, and a bolt rod is threaded onto the surface of the tube. The end of the bolt rod penetrates the circular tube and abuts against the drill. Two circular rings are integrally formed on the surface of the circular tube. This application allows the circular tube to be fixed to the surface of the electric drill via the bolt rod. When the electric drill drives the hole saw to make a hole in the non-combustible board, the abutment rings against the non-combustible board guide the drilling direction of the hole saw. During this process, the abutment rings, via a support rod, drive a sliding ring to slide on the surface of the circular tube. This achieves the purpose of adding a abutment ring to the outside of the electric drill, allowing the rings to abut against the non-combustible board and guide the hole saw during the hole-making process, thereby improving the verticality of the hole in the non-combustible board.

Description

Technical Field

[0001] This application relates to the field of opening holes in non-combustible boards, and in particular to a device for opening holes for water and electricity installation in non-combustible boards. Background Technology

[0002] As a fire-resistant decorative material, non-combustible boards require careful consideration of safety, functionality, and fire resistance when drilling holes for plumbing and electrical installations. The hole diameter and location must be determined based on the diameter of the plumbing and electrical pipes (e.g., a hole larger than 11cm is needed for a DN110 drain pipe) and the equipment installation requirements. Excessive drilling can damage the board structure. A hand drill equipped with a hole saw must be used when drilling holes in non-combustible boards.

[0003] When a hand drill drives a hole saw to drill holes in a non-combustible board, it is necessary to ensure that the hole saw is perpendicular to the non-combustible board. Otherwise, the hole will be offset. In actual operation, errors are inevitable, making it difficult to guarantee the perpendicularity of the hole in the non-combustible board. Therefore, a hole-drilling device for water and electricity installation holes in non-combustible boards is needed. A stop ring can be added to the outside of the hand drill so that the ring can abut against the non-combustible board and guide the hole saw during the drilling process, thereby improving the perpendicularity of the hole in the non-combustible board. Utility Model Content

[0004] To address the existing technical problems, this application provides a hole-opening device for water and electricity installation holes in non-combustible boards. By adding a stop ring to the outside of the electric drill, the ring can abut against the non-combustible board and guide the hole opener during the hole-opening process, thereby improving the verticality of the hole opening in the non-combustible board and solving the problems mentioned in the background art.

[0005] This application provides a hole-opening device for non-combustible board water and electricity installation holes, which adopts the following technical solution: A hole-opening device for non-combustible board water and electricity installation holes includes an electric drill: a hole opener is installed at the output end of the electric drill, a round tube is sleeved on the surface of the electric drill, a bolt rod is threaded on the surface of the round tube, the end of the bolt rod passes through the round tube and abuts against the electric drill, a first ring and a second ring are integrally formed on the surface of the round tube, a slip ring is slidably connected on the surface of the round tube, a spring is fixedly connected between the first ring and the slip ring, two symmetrically arranged support rods are welded to the surface of the slip ring, and abutment rings are welded to the ends of the support rods.

[0006] By adopting the above technical solution, the round tube is fixed to the surface of the electric drill by setting the bolt rod. When the electric drill drives the hole opener to make a hole in the non-combustible board, the drilling direction of the hole opener is guided by the abutment ring against the non-combustible board. During this process, the abutment ring will drive the sliding ring to slide on the surface of the round tube through the support rod. This achieves the purpose of adding a abutment ring on the outside of the electric drill, so that the ring can abut against the non-combustible board and guide the hole opener during the hole opening process, thereby improving the verticality of the hole in the non-combustible board.

[0007] Preferably, a washer is fitted on the surface of the bolt rod, and the washer is an elastic washer.

[0008] By adopting the above technical solution and setting the washer, the friction on the surface of the bolt rod is increased, which prevents the bolt rod from loosening and coming off due to external vibration, thereby improving the stability of the bolt rod installation.

[0009] Preferably, the surface of the round tube is integrally formed with a slider, and the inner wall of the slip ring is provided with a groove that matches the slider.

[0010] By adopting the above technical solution, the sliding of the slip ring on the surface of the circular tube is limited by the cooperation of the slider and the groove, which avoids the slip ring from deflecting when moving, thereby improving the stability of the slip ring when moving.

[0011] Preferably, a protective ring is attached to the surface of the abutment ring, and the protective ring is a rubber ring.

[0012] By adopting the above technical solution, the surface of the abutment ring is padded and protected by the setting of the protective ring, which avoids the situation where the surface of the non-combustible board is damaged when the abutment ring comes into direct contact with the non-combustible board, thereby improving the protection of the non-combustible board.

[0013] Preferably, the surface of the electric drill is integrally formed with a baffle, and the round tube abuts against the baffle.

[0014] Preferably, the surface of the electric drill is wrapped with a layer of braided tape.

[0015] By adopting the above technical solution and setting the wrapping layer, the friction on the surface of the electric drill is increased, which avoids the hand slipping when using the electric drill directly, thereby improving the reliability of holding the electric drill.

[0016] Preferably, the spring is a high-carbon steel spring.

[0017] In summary, this application includes at least one of the following beneficial technical effects: 1. This utility model uses a bolt rod to fix a round tube to the surface of an electric drill. When the electric drill drives the hole opener to drill a hole in the non-combustible board, the abutment ring guides the drilling direction of the hole opener by abutting against the non-combustible board. During this process, the abutment ring will drive the sliding ring to slide on the surface of the round tube through the support rod. This achieves the purpose of adding a abutment ring to the outside of the electric drill, so that the ring can abut against the non-combustible board and guide the hole opener during the drilling process, thereby improving the verticality of the hole in the non-combustible board.

[0018] 2. By using washers, this utility model increases the friction on the surface of the bolt rod, preventing the bolt rod from loosening and coming off due to external vibration, thereby improving the stability of the bolt rod installation.

[0019] 3. This utility model uses the combination of slider and groove to limit the sliding of the slip ring on the surface of the round tube, thereby preventing the slip ring from deflecting during movement and improving the stability of the slip ring during movement.

[0020] 4. By setting up a protective ring, this utility model pads and protects the surface of the abutment ring, avoiding damage to the surface of the non-combustible board when the abutment ring comes into direct contact with it, thus improving the protection of the non-combustible board.

[0021] 5. By adding a wrapping layer, this utility model increases the friction on the surface of the electric drill, preventing the hand from slipping when using the electric drill directly, thereby improving the reliability of holding the electric drill. Attached Figure Description

[0031] In addition, the term "multiple" should mean two or more.

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] Example 1: Combination Figures 1-4 This application discloses a hole-opening device for non-combustible board water and electricity installation holes, including an electric drill 1: a hole opener 2 is installed at the output end of the electric drill 1, a round tube 4 is sleeved on the surface of the electric drill 1, a bolt rod 5 is threaded on the surface of the round tube 4, the end of the bolt rod 5 passes through the round tube 4 and abuts against the electric drill 1, a first ring 7 and a second ring 8 are integrally formed on the surface of the round tube 4, a slip ring 9 is slidably connected on the surface of the round tube 4, a spring 10 is fixedly connected between the first ring 7 and the slip ring 9, and two symmetrically arranged support rods 13 are welded to the surface of the slip ring 9, and abutment rings 14 are welded to the ends of the support rods 13.

[0034] Example 2: Combination Figures 1-4A washer 6 is fitted onto the surface of the bolt rod 5. The washer 6 is an elastic washer. The washer 6 increases the friction on the surface of the bolt rod 5, preventing the bolt rod 5 from loosening or coming off due to external vibration, thereby improving the stability of the bolt rod 5 installation. A slider 11 is integrally formed on the surface of the round tube 4. The inner wall of the slip ring 9 has a groove 12 that matches the slider 11. Through the cooperation of the slider 11 and the groove 12, the sliding of the slip ring 9 on the surface of the round tube 4 is limited, preventing the slip ring 9 from deflecting during movement, thereby improving the stability of the slip ring 9 during movement. A protective plate ring 14 is attached to the surface of the plate ring 14. The protective ring 15 is a rubber ring. The protective ring 15 protects the surface of the abutment ring 14, preventing damage to the surface of the non-combustible board when the abutment ring 14 comes into direct contact with it, thus improving the protection of the non-combustible board. The surface of the electric drill 1 is integrally formed with a baffle 3, and the round tube 4 abuts against the baffle 3. The surface of the electric drill 1 is wrapped with a wrapping layer 16, which is a braided tape layer. The wrapping layer 16 increases the friction on the surface of the electric drill 1, preventing the hand from slipping when using the electric drill 1 directly, thus improving the reliability of holding the electric drill 1. The spring 10 is a high carbon steel spring.

[0035] Working principle: When using this utility model, the user fixes the round tube 4 to the surface of the electric drill 1 using the bolt rod 5. Then, the user holds the electric drill 1 and moves the abutment ring 14 to perpendicularly abut against the non-combustible board. The user then turns on the electric drill 1 and applies pressure to drive the hole opener 2 to make a hole in the non-combustible board. The abutment ring 14 and the non-combustible board guide the drilling direction of the hole opener 2. During this process, the abutment ring 14 will drive the sliding ring 9 to slide on the surface of the round tube 4 through the support rod 13, so that the sliding ring 9 presses against the surface of the round tube 4. When the spring 10 deforms, if the drilling is finished, the spring 10's rebound force will drive the abutment ring 14 to reset through the slip ring 9 and the support rod 13. Furthermore, the baffle 3 limits the position of the round tube 4 on the surface of the electric drill 1, preventing the round tube 4 from shifting on the surface of the electric drill 1 due to the reaction force when the electric drill moves to drill. This achieves the addition of an abutment ring on the outside of the electric drill, allowing the ring to abut against the non-combustible board and guide the hole opener during the drilling process, thereby improving the verticality of the non-combustible board drilling.

[0036] In summary, this non-combustible board electrical and plumbing installation hole drilling device, through the setting of bolt rod 5, fixes the round tube 4 to the surface of the electric drill 1. When the electric drill 1 drives the hole opener 2 to drill a hole in the non-combustible board, the abutment ring 14 abuts against the non-combustible board to guide the drilling direction of the hole opener 2. During this process, the abutment ring 14 will drive the sliding ring 9 to slide on the surface of the round tube 4 through the support rod 13. This achieves the purpose of adding abutment ring to the outside of the electric drill, so that the ring abuts against the non-combustible board and guides the hole opener during the drilling process, thereby improving the verticality of the non-combustible board hole.

[0037] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
