Description

Technical Field

[0001] This application relates to the field of corner measurement technology, and in particular to an angle measuring device. Background Technology

[0002] In many fields, including interior decoration, accurate measurement of wall corner angles is crucial. During interior decoration, accurate measurement of wall corner angles helps ensure precise cutting of furniture, decorative moldings, etc., improves installation fit, and enhances the overall decoration effect. Angle measuring instruments are widely used to measure wall corner angles. Users typically transfer the measured angle measuring instrument to a cutting machine and adjust the angle of the saw blade according to the measured angle to achieve precise cutting of decoration materials.

[0003] In related technologies, such as Chinese Patent Publication No. CN216432816U, a corner measuring device is disclosed, including a support bar and a reading unit. The support bar has a large rotating shaft installed in the mounting hole at the left end of its upper surface. The lower end of the large rotating shaft extends out of the lower surface of the support bar and is symmetrically connected to a connecting rod at the end. The upper surface of the connecting rod is provided with a sliding groove. A sliding sleeve is slidably connected to the middle of the outer surface of the support bar. Connecting bars are provided on both the front and rear sides of the sliding sleeve. A sliding column is provided at the end of the lower surface of the connecting bar away from the sliding sleeve. The sliding column is slidably connected to the sliding groove. The reading unit is located at the rear end of the upper surface of the connecting bar on the rear side. The lower end of the reading unit is slidably connected to the sliding groove on the rear side. It also includes a scale line, which is located at the lower end of the front side of the connecting rod on the front side.

[0004] Regarding the aforementioned technologies, when the aforementioned corner measuring device measures the angle of a corner, the included angle between the two connecting rods is limited by the length of the connecting strip and the sliding distance of the sliding sleeve. It can only measure the angle of an inside corner and cannot measure the angle of an outside corner, so there is still room for improvement. Utility Model Content

[0005] To address the issue that corner measuring devices can only measure the angle of inside corners and cannot measure the angle of outside corners, this application provides an angle measuring device.

[0006] The angle measuring instrument provided in this application adopts the following technical solution:

[0007] An angle measuring device includes a mounting base, a first ruler frame rotatably connected to the mounting base, a first extension ruler slidably connected to the first ruler frame along the length direction of the first ruler frame, a second ruler frame rotatably connected to the mounting base, and a second extension ruler slidably connected to the second ruler frame along the length direction of the second ruler frame. The first ruler frame and the second ruler frame are rotatably connected, and the lower surface of the first extension ruler is at a height higher than the upper surface of the second extension ruler.

[0008] By adopting the above technical solution, when it is necessary to measure the angle of an external corner, the first extension ruler is slid towards the side closer to the rotating connection between the first and second ruler frames, so that one side of the first extension ruler extends beyond the first ruler frame. At the same time, the second extension ruler is slid towards the side closer to the rotating connection between the first and second ruler frames, so that one side of the second extension ruler extends beyond the second ruler frame. The extended part of the first extension ruler abuts against the wall surface on one side of the external corner, and the extended part of the second extension ruler abuts against the wall surface on the other side of the external corner. At this time, the angle of the external corner can be measured, which improves the versatility of the angle measuring device in measuring wall corner angles. On the other hand, the lower surface of the first extension ruler is at a higher height than the upper surface of the second extension ruler, which avoids interference between the first and second extension rulers during the measurement of the external corner angle, improving the convenience for users to use the angle measuring device.

[0009] Optionally, the first ruler frame is integrally provided with a first gear, and the second ruler frame is integrally provided with a second gear that meshes with the first gear, wherein the first gear and the second gear have the same number of teeth.

[0010] By adopting the above technical solution, the first and second gears with the same number of teeth mesh to achieve synchronous rotation of the first and second rulers, ensuring that the angles at which the first and second rulers rotate toward or away from each other are consistent, and improving the stability of the mounting base always being on the centerline of the angle formed by the first and second rulers.

[0011] Optionally, a mounting post for the second gear to be fitted is fixedly connected to the mounting base, and a locking block is threadedly connected to the side of the mounting post away from the mounting base. When the locking block abuts against the second gear, the second gear is locked.

[0012] By adopting the above technical solution, when it is necessary to lock the angle between the first frame and the second frame, the locking block is rotated. As the locking block is rotated on the mounting column, the locking block will gradually press against the second gear, exert pressure on the second gear, restrict the rotation of the second gear, and improve the stability of the first frame and the second frame in a specific angle state.

[0013] Optionally, the locking block has a marking on the side away from the second gear to indicate the rotation direction for locking and unlocking.

[0014] By adopting the above technical solution and setting clear rotation direction markings, users can intuitively understand how to operate the locking block, avoiding inaccurate angle measurement or interruption of the measurement process due to misoperation, and further improving the ease of use and operating efficiency of the angle measuring device.

[0015] Optionally, the first extension ruler is provided with a first mounting groove for the first ruler frame to be fitted, and the first ruler frame integrally extends a first abutting block that abuts against the side of the first extension ruler away from the first mounting groove.

[0016] By adopting the above technical solution, the first embedding groove enables the first extension ruler and the first ruler frame to form a tight fitting structure, which restricts the shaking or displacement of the first extension ruler during the sliding process; at the same time, the first abutting block limits the first extension ruler from the side away from the first embedding groove, preventing the first extension ruler from detaching from the first ruler frame from the side away from the first embedding groove, thereby improving the smoothness and stability of the first extension ruler sliding on the first ruler frame.

[0017] Optionally, a cover plate is fixedly connected to the mounting base.

[0018] By adopting the above technical solution, the gears, mounting columns and other components on the mounting base are protected, reducing the entry of external dust and debris that may affect the normal use of the measuring instrument and improving the service life of the angle measuring instrument.

[0019] Optionally, the cover plate is provided with positioning lines to assist the user in positioning the saw blade of the cutting machine.

[0020] By adopting the above technical solution, and by setting positioning lines on the cover plate to assist users in positioning the saw blade of the cutting machine, users can quickly and accurately position the saw blade of the cutting machine to the required angle position, thereby improving the accuracy and efficiency of cutting and enhancing the practicality and ease of use of the angle measuring device.

[0021] Optionally, the mounting base is fixedly connected to a boss for positioning the angle measuring device when it is mounted on the cutting machine.

[0022] By adopting the above technical solution, the angle measuring device is snapped onto the cutting machine by the boss on the mounting base, which avoids the angle measuring device from shifting during the adjustment of the cutting angle and improves the stability of installing the angle measuring device on the cutting machine.

[0023] Optionally, the first ruler frame is integrally provided with a first gripping part for the user to hold, and the second ruler frame is integrally provided with a second gripping part for the user to hold.

[0024] By adopting the above technical solution, when the user needs to adjust the angle of the first and second rulers, holding the first and second grips allows for easier rotation of the rulers, improving the convenience of operation.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. By placing the extended portions of the first and second extension rulers against the walls on both sides of the external corner, the angle of the external corner can be measured, thus improving the versatility of the angle measuring device in measuring wall corner angles;

[0027] 2. The first and second extension rulers have a height difference, which avoids interference between the first and second extension rulers during the measurement process and improves the convenience for users to use the angle measuring instrument;

[0028] 3. Rotating the locking block to press against the second gear can restrict the rotation of the second gear, thereby improving the stability of the first and second frames in maintaining a specific angle. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0037] This application discloses an angle measuring device.

[0038] Reference Figure 1 and Figure 2 The angle measuring device includes a mounting base 1, a first measuring ruler 2, and a second measuring ruler 3. Both the first measuring ruler 2 and the second measuring ruler 3 are rotatably connected to the mounting base 1, and the two work together to measure the corner angle.

[0039] Reference Figure 3 The first measuring ruler 2 includes a first ruler frame 21 and a first extension ruler 22. The second measuring ruler 3 includes a second ruler frame 31 and a second extension ruler 32. A rotating column 11 is mounted on the mounting base 1. A first gear 211 is integrally connected to the first ruler frame 21 and is sleeved on the rotating column 11 to achieve rotatable connection of the first ruler frame 21 to the mounting base 1. A mounting column 12 is also fixedly connected to the mounting base 1. A second gear 311 is integrally connected to the second ruler frame 31 and is sleeved on the mounting column 12 to achieve rotatable connection of the second ruler frame 31 to the mounting base 1. The first gear 211 and the second gear 311 have the same number of teeth and mesh with each other to make the first ruler frame 21 and the second ruler frame 31 rotate synchronously, and the rotation angles of the first ruler frame 21 and the second ruler frame 31 are the same.

[0040] Reference Figure 3 A locking block 121 is threaded onto the side of the mounting post 12 away from the mounting base 1. When the locking block 121 is tightened towards the side of the mounting base 1 so that it presses against the second gear 311, the second gear 311 is locked, and the first frame 21 and the second frame 31 cannot rotate. The side of the locking block 121 away from the second gear 311 also has a mark 122 to indicate to the user the rotation direction corresponding to locking and unlocking the second gear 311.

[0041] Reference Figure 4 and Figure 5 To facilitate user adjustment of the angles of the first ruler frame 21 and the second ruler frame 31, a first gripping part 212 for the user to hold is integrally connected to the first ruler frame 21, and a second gripping part 312 for the user to hold is integrally connected to the second ruler frame 31. The first extension ruler 22 has a first embedding groove 221 that extends through both sides of the first extension ruler 22 along its length. The first extension ruler 22 is fitted onto the first ruler frame 21 through the first embedding groove 221, allowing it to slide along the length of the first ruler frame 21. Several first abutting blocks 213 are integrally connected to the first ruler frame 21. In this application, two first abutting blocks 213 are used as an example. Both first abutting blocks 213 abut against the side of the first extension ruler 22 away from the first embedding groove 221 to prevent the first extension ruler 22 from detaching from the first ruler frame 21 from the side away from the first embedding groove 221.

[0042] Reference Figure 4 and Figure 5 The second extension ruler 32 has a second embedding groove 321, which extends through both sides of the second extension ruler 32 along its length. The second extension ruler 32 is fitted onto the second ruler frame 31 through the second embedding groove 321, allowing the second extension ruler 32 to slide and connect to the second ruler frame 31 along its length. A plurality of second abutment blocks 313 are integrally connected to the second ruler frame 31. In this application, two second abutment blocks 313 are used as an example. Both second abutment blocks 313 abut against the side of the second extension ruler 32 away from the second embedding groove 321 to prevent the second extension ruler 32 from detaching from the second ruler frame 31 from the side away from the second embedding groove 321.

[0043] Reference Figure 5 To avoid interference between the first extension ruler 22 and the second extension ruler 32 during the measurement of the external angle, the lower surface of the first extension ruler 22 is at a higher height than the upper surface of the second extension ruler 32.

[0044] Reference Figure 1 A cover plate 13 is fixedly connected to the mounting base 1 to prevent dust, debris, etc. from entering and affecting the normal use of the angle measuring instrument. The side of the cover plate 13 away from the mounting base 1 has a positioning line 131 to facilitate the user's positioning of the saw blade of the cutting machine.

[0045] Reference Figure 6 The mounting base 1 is fixedly connected to a boss 14, so that the user can position and fix the angle measuring device on the cutting machine.

[0046] The implementation principle of an angle measuring device according to an embodiment of this application is as follows: When it is necessary to measure the angle of a concave corner, hold the first holding part 212 and / or the second holding part 312, rotate the first ruler frame 21 and the second ruler frame 31 so that the first extension ruler 22 and the second extension ruler 32 respectively abut against the two side walls of the concave corner, and then rotate the locking block 121 to lock the second gear 311, so that the included angle between the first ruler frame 21 and the second ruler frame 31 is fixed.

[0047] When it is necessary to measure the angle of the external corner, push the first extension ruler 22 to slide towards the side closer to the first gear 211, so that one side of the first extension ruler 22 extends outside the first ruler frame 21. Push the second extension ruler 32 to slide towards the side closer to the second gear 311, so that one side of the second extension ruler 32 extends outside the second ruler frame 31. Then hold the first grip part 212 and / or the second grip part 312, rotate the first ruler frame 21 and the second ruler frame 31, so that the outwardly extending sides of the first extension ruler 22 and the second extension ruler 32 respectively abut against the two side walls of the external corner. Then rotate the locking block 121 to lock the second gear 311, so that the included angle between the first ruler frame 21 and the second ruler frame 31 is fixed.

[0048] When it is necessary to cut decoration materials, the angle measuring device is fixedly installed on the cutting machine through the boss 14, and then the saw blade of the cutting machine is rotated to align with the positioning line 131 to adjust the cutting angle.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
