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] Baseboards are an important part of interior design, protecting the wall areas that are frequently kicked, reducing impact damage, and preventing damage from external collisions. To ensure a better fit between the baseboard and the wall at corners, and between two baseboards themselves, the mating surfaces of the two baseboards usually need to be cut. The cutting angle is determined based on the angle of the corresponding wall corner.

[0003] An angle gauge is a tool used to measure the actual angle of a wall corner during baseboard installation, which is especially important when dealing with irregularly shaped baseboards. Related technologies include Chinese Patent Publication No. CN216432816U, which discloses a wall corner measuring device for interior decoration construction, comprising a support bar and a reading unit; a large rotating shaft is provided in the mounting hole at the left end of the upper surface of the support bar, and 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; each connecting rod has a groove on its upper surface; a sliding sleeve is slidably connected to the middle of the outer surface of the support bar; connecting strips are provided on both the front and rear sides of the sliding sleeve; a sliding post is provided at the lower surface of the connecting strip away from the sliding sleeve, and the sliding post is slidably connected to the groove; a baffle is fixedly connected to the side of the support bar away from the large rotating shaft; a spring is also sleeved on the outer surface of the support bar, the spring being located between the baffle and the sliding sleeve and in a compressed state; a hand-tightening bolt is provided on the sliding sleeve for locking the sliding sleeve.

[0004] Regarding the aforementioned technologies, when using the aforementioned corner measuring device to measure the angle of a corner, when tightening the hand-tightening bolt to lock the measuring device, it is necessary to always apply a pushing force to keep the device pressed against the wall surface, so as to avoid the sliding sleeve sliding excessively towards the side closer to the large rotating shaft under the action of the spring force, which would cause the included angle between the two connecting rods to be too large, resulting in a large error in the measurement result. There is still room for improvement. Utility Model Content

[0005] In order to improve the problem that when using the above-mentioned corner measuring device to measure the angle of a corner, it is necessary to always apply a pushing force to keep the device pressed against the wall to avoid the sliding sleeve sliding excessively towards the side closer to the large pivot under the elastic force of the spring, this application provides an angle measuring device.

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

[0007] An angle gauge includes a mounting base, a measuring component, and a locking component for locking the measuring component. The measuring component includes two angle gauges, one end of which is fixedly connected to a rotating gear. Both rotating gears are rotatably connected to the mounting base and mesh with each other.

[0008] By adopting the above technical solution, since the two rotating gears mesh with each other, when one angle gauge rotates, it will drive the other angle gauge to rotate synchronously through gear meshing, thereby expanding the included angle between the two angle gauges, so as to measure the angle of the corner of the wall. Compared with the spring force drive, the driving method of this application does not need to apply a pushing force to press against the wall during the locking process to avoid excessive slippage of the sliding sleeve due to the spring force, thus improving the convenience of locking the angle gauge for users.

[0009] Optionally, both rotating gears may have the same number of teeth and module.

[0010] By adopting the above technical solution, the two rotating gears have the same number of teeth and module, which ensures that the transmission ratio of the two rotating gears is 1:1. This makes the angles at which the two angle gauges open to both sides the same, improving the stability of the mounting base, which is always on the center line of the angle formed by the two angle gauges.

[0011] Optionally, the locking assembly includes a locking cylinder and a locking block. A rotating column for the rotating gear to be rotatably mounted is fixedly connected to the mounting base. The locking cylinder is sleeved on the rotating column and fixedly connected to the rotating gear. The locking block is threadedly connected to the rotating column and is located on the side of the locking cylinder away from the rotating gear.

[0012] By adopting the above technical solution, when it is necessary to lock the angle of the two angle gauges, the locking block is rotated. As the locking block is rotated on the rotating column, the locking block will gradually press against the locking cylinder, thereby creating pressure on the rotating gear that is fixedly connected to the locking cylinder, restricting the rotation of the rotating gear, and thus locking the angle of the measuring component, improving the stability of the two angle gauges in a specific included angle state.

[0013] Optionally, an adjusting gear is rotatably connected to the mounting base, the adjusting gear meshes with one of the rotating gears, and an adjusting wrench for locking the adjusting gear is fixedly connected to the adjusting gear.

[0014] By adopting the above technical solution, when the two angle rulers open to different angles, the adjusting gear is locked by adjusting the wrench, thereby locking the rotating gear meshing with the adjusting gear. At this time, rotating the other angle ruler forces the corresponding rotating gear to undergo tooth groove displacement, thereby adjusting the opening angles of the two angle rulers to the same state, improving the convenience for users to adjust the relative displacement of the two angle rulers.

[0015] Optionally, the angle ruler includes an angle ruler frame fixedly connected to the rotating gear and an extension angle ruler slidably connected to the angle ruler frame.

[0016] By adopting the above technical solution, when it is necessary to measure the outer angle of a wall corner, push the extension angle ruler so that it slides along the angle ruler frame towards the side closer to the rotating gear to a suitable position, and then place the extension angle ruler against the two wall surfaces of the outer corner for measurement. Since the opposite angles of two straight lines are equal, the angle of the outer corner is equal to the angle between the two angle ruler frames. When it is necessary to measure the inner angle of a wall corner, push the extension angle ruler so that it slides along the angle ruler frame away from the rotating gear to a suitable position, and then place the extension angle ruler against the two wall surfaces of the inner corner for measurement. The angle between the two angle ruler frames is the angle of the inner corner, thus improving the versatility of the angle ruler.

[0017] Optionally, the angle ruler frame is provided with a limiting groove on the side away from the rotating gear, and a limiting block is fixedly connected to the extended angle ruler. When the extended angle ruler slides towards the side closer to the rotating gear, the limiting block abuts against the groove wall of the limiting groove.

[0018] By adopting the above technical solution, the sliding distance of the extended angle ruler on the angle ruler frame towards the rotating gear is limited by the cooperation of the limiting block and the groove wall of the limiting groove. This prevents the extended angle ruler from sliding excessively towards the rotating gear and detaching from the angle ruler frame, thus improving the stability of the extended angle ruler sliding and connecting to the angle ruler frame. On the other hand, the cooperation between the limiting block and the groove wall of the limiting groove ensures that the extended angle ruler and the angle ruler frame overlap by a certain distance in their own length direction. This overlap ensures the stability that the length direction of the extended angle ruler and the length direction of the angle ruler frame are on the same straight line, thus improving the accuracy of the angle measuring device in measuring the angle of the wall corner.

[0019] Optionally, a panel is fixedly connected to the mounting base, the panel is provided with scale markings, and a pointer that cooperates with the scale markings to read the value is fixedly connected to the rotating gear.

[0020] By adopting the above technical solution, the pointer and the angle ruler rotate synchronously. The rotation angle of the pointer is the same as the rotation angle of the angle ruler. When the 0 mark of the scale is aligned with the initial position of the pointer, since the scale marks are stationary with the panel, the user can read the rotation angle by the position indicated by the pointer on the scale marks, which improves the convenience for the user to read the angle of the corner.

[0021] Optionally, the mounting base is provided with a boss for engaging the angler onto the cutting machine.

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

[0023] Optionally, the panel is provided with scale lines for adjusting and positioning the saw blade or laser beam of a cutting machine equipped with an angler, in conjunction with the boss.

[0024] By adopting the above technical solution, the scale lines assist users in adjusting the position of the saw blade or laser beam, which improves the accuracy of the adjustment position and reduces the cutting angle error compared to direct adjustment.

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

[0026] 1. By rotating the gears, the two angle gauges rotate synchronously, increasing the included angle between them and improving the convenience of measuring the angle of the wall corner for users;

[0027] 2. The fact that the two rotating gears have the same number of teeth and module ensures that the transmission ratio of the two rotating gears is 1:1, which improves the stability of the mounting base, which is always on the center line of the angle formed by the two angle gauges.

[0028] 3. By extending the angle ruler on the angle ruler frame and sliding it towards or away from the rotating gear, the angle of the outer or inner wall corner can be measured, thus improving the versatility of the angle ruler. Attached Figure Description

[0037] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0038] This application discloses an angle measuring device.

[0039] Reference Figure 1 The angle measuring device includes a mounting base 1, a measuring component 2, a locking component 3, and a reading component 4. The measuring component 2 is rotatably connected to the mounting base 1 to measure the angle at the corner of the wall. The locking component 3 is mounted on the mounting base 1 to lock the rotation angle of the measuring component 2. The reading component 4 is mounted on the mounting base 1 for the user to read the data obtained by the measuring component 2.

[0040] Reference Figure 2 and Figure 3 The measuring component 2 includes two angle gauges 21, each comprising an angle gauge frame 211 and an extension angle gauge 212. A rotating gear 2111 is fixedly connected to the angle gauge frame 211. A rotating column 11 is fixedly connected to the mounting base 1 for rotating the rotating gears 2111. The rotating gears 2111 are fitted one-to-one onto the rotating column 11 to achieve a rotatable connection between the angle gauges 21 and the mounting base 1. The two rotating gears 2111 have the same module and mesh with each other, so that when the user rotates one angle gauge 21, the other angle gauge 21 is driven by the rotating gear 2111 and rotates synchronously. The two rotating gears 2111 also have the same number of teeth, ensuring that the rotation amplitude of the two angle gauges 21 is the same. The rotating gears 2111 are made of plastic. When one rotating gear 2111 is locked, the other rotating gear 2111 can be forced to displace its tooth grooves, allowing adjustment when the rotation angles of the two angle gauges 21 are asymmetrical.

[0041] Reference Figure 4An angle ruler frame 211 has an integrally connected limiting strip 2112 for sliding installation of an extension angle ruler 212. The extension angle ruler 212 has a sliding groove 2121 arranged along its length. The extension angle ruler 212 is fitted onto the limiting strip 2112 through the sliding groove 2121, allowing it to slide along its length on the angle ruler frame 211. To prevent the extension angle ruler 212 from detaching from the angle ruler frame 211 from the side away from the limiting strip 2112, an abutment block 2113 is fixedly connected to the side of the angle ruler frame 211 closest to the limiting strip 2112. The abutment block 2113 abuts against the side of the extension angle ruler 212 away from the limiting strip 2112.

[0042] Reference Figure 4 and Figure 5 The angle ruler holder 211 has a limiting groove 2114 on the side away from the rotating gear 2111, and the limiting groove 2114 is arranged along the sliding direction of the extended angle ruler 212. A limiting block 2122 is fixedly connected to the extended angle ruler 212, and the limiting block 2122 cooperates with the groove wall of the limiting groove 2114 to limit the distance the extended angle ruler 212 slides towards the side closer to the rotating gear 2111. When the extended angle ruler 212 slides towards the side closer to the rotating gear 2111, the limiting block 2122 abuts against the groove wall of the limiting groove 2114. The lower side wall of one extended angle ruler 212 is higher than the upper side wall of the other extended angle ruler 212 to avoid interference between the two extended angle rulers 212 when rotating the angle ruler 21 after the extended angle ruler 212 has slid towards the side closer to the rotating gear 2111.

[0043] Reference Figure 6 To adjust the rotation angles of the two angle gauges 21 when they are asymmetrical, an adjustment assembly 12 is mounted on the mounting base 1. The adjustment assembly 12 includes an adjustment gear 121 and an adjustment wrench 122. The adjustment gear 121 is rotatably connected to the mounting base 1. The adjustment gear 121 has the same module as the rotating gear 2111, and meshes with one of the rotating gears 2111 so that locking the adjustment gear 121 locks the meshing rotating gear 2111. The adjustment wrench 122 is fixedly connected to the adjustment gear 121 so that the user can limit the rotation of the adjustment gear 121 by pressing or holding the adjustment wrench 122.

[0044] Reference Figure 6The locking assembly 3 includes a locking cylinder 31 and a locking block 32. The locking cylinder 31 is sleeved on one of the rotating columns 11 and is fixedly connected to a rotating gear 2111 sleeved on the rotating column 11. The locking block 32 includes a connecting portion 321 threadedly connected to the rotating column 11 and a grip portion 322 fixedly connected to the connecting portion 321 for the user to hold. The locking block 32 is located on the side of the locking cylinder 31 away from the rotating gear 2111, so that when the grip portion 322 is rotated and pressed against the locking cylinder 31, the rotating gear 2111 is locked.

[0045] Reference Figure 6 The reading assembly 4 includes a panel 41 and a pointer 42. The panel 41 is fixedly connected to the mounting base 1, and a scale mark 411 is provided on the side of the panel 41 away from the mounting base 1. The pointer 42 includes a mounting part 421 fixedly connected to a rotating gear 2111 and an indicator part 422 for pointing to the scale mark 411. The indicator part 422 is fixedly connected to the mounting part 421 so that the indicator part 422 rotates as the rotating gear 2111 rotates. The scale mark 411 and the indicator part 422 cooperate to provide the reading of the angle gauge.

[0046] Reference Figure 6 and Figure 7 To facilitate the installation of the angle gauge on the cutting machine, a boss 13 is fixedly connected to the mounting base 1, allowing the user to snap the angle gauge onto the cutting machine. The panel 41 also has a scale line 412, so that when the user snaps the angle gauge onto the cutting machine using the boss 13, the user can align the saw blade or laser beam of the cutting machine with the scale line 412 for adjustment and positioning.

[0047] The implementation principle of an angle gauge according to an embodiment of this application is as follows: Position the end of the angle gauge closest to the rotating gear 2111 towards the corner of the wall, and rotate one of the angle rulers 21 so that both angle rulers 21 abut against the wall. When measuring the angle of an outer wall corner, push the extension angle ruler 212 to slide it along the angle ruler frame 211 towards the side closest to the rotating gear 211 to a suitable position for measurement. When measuring the angle of an inner wall corner, push the extension angle ruler 212 to slide it along the angle ruler frame 211 away from the rotating gear 211 to a suitable position. After measurement, rotate the grip 322 to lock the rotating gear 2111. At this time, the angle of the corner can be read by the pointer 42 and the scale mark 411. Then, the angle gauge is attached to the cutting machine by the boss 13. Align the saw blade or laser beam of the cutting machine with the scale line 412 to adjust the cutting angle. When the rotation angles of the two angle gauges 21 are not symmetrical, press the grip 322 and lock one of the rotating gears 2111 by adjusting the gear 121. Then, force the rotation of the angle gauge 21, which is fixedly connected to the other rotating gear 2111, to adjust it.

[0048] 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.
