Description

Technical Field

[0001] This utility model relates to the field of measuring device technology, and in particular to an easy-to-store angle measuring device. Background Technology

[0002] A mechanical angle measuring instrument is a tool used to measure and determine angles. It is widely used in mechanical engineering, construction, woodworking, metal processing and other fields. These tools usually measure and display angles through mechanical structures. Common types include angle rulers, angle gauges and angle meters.

[0003] By comparing a corner angle measuring device with patent publication number CN220288505U, it can be seen that although this device can quickly measure the corner angle of a building, and is simple and quick to operate, saving time and effort, it may be inconvenient to carry and store the measuring device due to its excessive length after use, and may be damaged by collision.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figures 1-5 As shown, a retractable angle measuring device includes a measuring chassis 100 and a measuring mechanism for measuring mechanical angles, the measuring mechanism being located above the measuring chassis 100.

[0026] In this embodiment: the measuring mechanism includes a turntable 201 rotatably disposed at the center of the measuring chassis 100, a base plate 211 fixed at the bottom of the turntable 201, a torsion spring 209 connected between the base plate 211 and the measuring chassis 100, a first measuring frame 202 fixed at the horizontal position of the turntable 201, a first scale 203 provided at the upper end of the first measuring frame 202, a second measuring frame 213 provided at the front side of the first measuring frame 202, the second measuring frame 213 fixedly connected to the measuring chassis 100, a second scale 214 provided at the upper end of the second measuring frame 213, an index 207 fixed at the rear end of the turntable 201, a circumferential scale 208 provided around the measuring chassis 100, and a storage component provided inside the first measuring frame 202 and the second measuring frame 213.

[0027] The storage assembly includes a first measuring plate 204 that is slidably disposed inside the first measuring frame 202, a first locking bolt 205 provided between the first measuring plate 204 and the first measuring frame 202, and a second measuring plate 217 that is slidably installed inside the second measuring frame 213, a second locking bolt 218 provided between the second measuring plate 217 and the second measuring frame 213.

[0028] A first counterweight 220 is fixed at the lower end of the first measuring frame 202, and a second counterweight 219 is fixed at the lower end of the second measuring frame 213. A first buffer post 212 is provided on both sides of the first counterweight 220, and a first buffer spring is provided on the outside of the first buffer post 212. A second buffer post 216 is provided on both sides of the second counterweight 219, and a second buffer spring is provided on the outside of the second buffer post 216.

[0029] A sponge pad 210 is provided at the bottom of the base plate 211, and a hand sleeve 221 is fixed at the lower end of the turntable 201. The hand sleeve 221 is made of rubber. A first light 206 is installed on the side wall of the first measuring frame 202, and a second light 215 is installed on the side wall of the second measuring frame 213. A measuring workpiece 222 is provided between the first measuring frame 202 and the second measuring frame 213. The length and angle of the measuring part are measured from all directions through the measuring mechanism. The measuring mechanism can be stored through the storage component. This enables the measurement of the angle of the measuring part with a large width, increases the measuring range of the measuring device, and solves the problem that the measuring device is too long and inconvenient to carry. It also reduces the possibility of the measuring device being damaged by collision.

[0030] Working principle: First, the measuring workpiece 222 is inserted between the first measuring frame 202 and the second measuring frame 213, causing the first measuring frame 202 to rotate along the measuring base 100, which in turn drives the index 207 to rotate. The angle of the measuring workpiece 222 can be determined by the rotation angle of the index 207 on the measuring base 100. At the same time, the length of the hypotenuse of the measuring workpiece 222 can also be measured by the first measuring frame 202 and the second measuring frame 213.

[0031] When measuring a relatively long workpiece 222, the first locking bolt 205 and the second locking bolt 218 are rotated in opposite directions to pull out the first measuring plate 204 and the second measuring plate 217, increasing the measuring length of the first measuring frame 202 and the second measuring frame 213, thus allowing for the measurement of the longer workpiece 222. After the measurement is completed, the first measuring plate 204 and the second measuring plate 217 are retracted into the first measuring frame 202 and the second measuring frame 213 for storage. This solves the problem of the measuring device being too long and inconvenient to carry, and reduces the possibility of the measuring device being damaged by collision. At the same time, the first lighting lamp 206 and the second lighting lamp 215 can provide lighting for the measuring device to perform measurements at night.

[0032] When the device is accidentally dropped during the measurement process, the first buffer post 212 and the second buffer post 216 at the lower end of the first measuring frame 202 and the second measuring frame 213 will cushion the device, reduce the impact force between the device and the ground, and provide better protection for the device.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
