When measuring the angle of a building, the staff can press the cross plate against one side of the building corner and rotate the rotating rod. One end of the rotating rod is slidably connected to the arc plate until the other end of the rotating rod presses against the other side of the building corner. The staff can read the scale at the sliding position of one end of the rotating rod and the arc plate, so as to determine the angle size of the building. For buildings with different angles, the position at the sliding position of the rotating rod and the arc plate is different after the rotating rod rotates. The staff only needs to read the corresponding scale to determine the angle size of the building, thus expanding the applicable range of the corner measurement instrument.

[0003] For the above-mentioned corner measurement instrument for engineering supervision patrol, although the applicable range of the corner measurement instrument is expanded, the overall structure is fixed, and it is not convenient to adjust the measurement area according to the actual size of the building corner, so the measurement accuracy of the corner is easily reduced due to measurement interference.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0022] Embodiment 1

[0023] Please refer to Figures 1-6 , a corner measurement instrument for engineering supervision inspection shown in the figure, including a first measuring plate 101 and a second measuring plate 102, and further including a rotating shaft 2 provided on the first measuring plate 101. The second measuring plate 102 is rotatably connected to the side wall of the rotating shaft 2. A pointer 3 is provided on the side wall of the rotating shaft 2 away from the first measuring plate 101. A plurality of angle scale lines 4 are opened on the side of the second measuring plate 102 close to the pointer 3;

[0024] It should be noted here that: through the angle difference between the first measuring plate 101 and the second measuring plate 102, and through the position of the pointer 3 on the angle scale line 4, the angle measurement of the building can be realized, and the rotation range of the second measuring plate 102 is relatively large, thus expanding the applicable range of corner measurement.

[0025] Please refer to Figure 3 , the first measuring plate 101 and the second measuring plate 102 shown in the figure are provided with an adjustment assembly for adapting to the corner measurement area. The adjustment assembly includes an adjustment hole 501 opened at one end of the first measuring plate 101 away from the rotating shaft 2. An adjustment plate 502 is slidably connected to the adjustment hole 501. A measuring sub-plate 503 is fixedly connected to the end of the adjustment plate 502 away from the first measuring plate 101. The adjustment plate 502 is provided with a locking assembly for locking with the first measuring plate 101;

[0026] It should be noted here that by adjusting the settings of the components, the limitations of the building measurement space are adapted, thereby reducing measurement interference, improving the flexibility of measurement, and further ensuring the accuracy of corner measurement.

[0027] Please refer to Figure 6 , in the illustrated locking assembly, a plurality of locking cavities 601 are formed in opposite two side walls of the adjusting plate 502. Each locking cavity 601 is slidably connected with a locking rod 602. One end of each locking rod 602 close to the inner wall of the adjusting hole 501 is rounded at a corner 603. Locking holes 604 are formed in opposite two inner walls of the adjusting hole 501. The two locking holes 604 are arranged to match the locking rods 602. Each locking cavity 601 is provided with an extrusion assembly for extruding the locking rod 602;

[0028] It should be noted here that by the setting of the locking assembly, when the measurement sub-plate 503 is moved, under the interaction force between the rounded corner 603 and the locking hole 604 and the guiding action of the extrusion assembly, the locking rod 602 will be pushed to contract into the locking cavity 601, so as to facilitate the movement of the measurement sub-plate 503. When the measurement sub-plate 503 is moved an appropriate length, the locking rod 602 will be pushed into the locking hole 604 and abut against the bottom wall of the locking hole 604 under the reset action of the extrusion assembly. Thus, through the abutting action of the locking rod 602, the limiting of the adjusting plate 502 is realized, and further the stability of the measurement sub-plate 503 during use is ensured.

[0029] Please refer to Figure 6 , in the illustrated extrusion assembly, an extrusion plate 701 is slidably connected to the locking cavity 601. One end of the locking rod 602 away from the locking hole 604 is connected to the extrusion plate 701. A first spring 702 is arranged on the side of the extrusion plate 701 away from the locking rod 602. The other end of the first spring 702 is connected to the bottom wall of the locking cavity 601;

[0030] It should be noted here that by the setting of the extrusion assembly, a guiding and resetting function is provided for the locking rod 602.

[0031] Working principle: When measuring the building corner, the first measuring plate 101 is abutted against one side of the building, and then the second measuring plate 102 is rotated to align with the building corner to be measured. During the rotation of the second measuring plate 102, the angle scale line 4 will be driven to rotate synchronously. Thus, the angle measurement of the building can be realized through the position of the pointer 3 on the angle scale line 4, and the rotation range of the second measuring plate 102 is relatively large, thereby expanding the applicable range of corner measurement;

[0032] During the measurement process, the telescopic movement of the measurement auxiliary plate 503 can be used to adapt to the limitations of the building measurement space, thereby reducing measurement interference, improving the flexibility of measurement, further ensuring the accuracy of corner measurement. At the same time, under the action of the limit component, it is convenient to store and limit the first measurement plate 101 and the second measurement plate 102, thereby improving the portability of the measurement device while ensuring the stability during storage and placement.

[0033] Embodiment 2

[0034] Please refer to Figure 5 , this embodiment further illustrates Embodiment 1. The measurement auxiliary plate 503 at one end of the first measurement plate 101 in the figure is provided with a limit component for storing and limiting the second measurement plate 102. The limit component includes a T-shaped rod 801 fixedly connected to the side of the measurement auxiliary plate 503 away from the first measurement plate 101. A limit plate 802 is sleeved on the T-shaped rod 801, and a limit hole 803 is opened on the limit plate 802. A limit rod 804 is fixedly connected to the side of the measurement auxiliary plate 503 at one end of the second measurement plate 102 away from the rotating shaft 2, and the limit rod 804 is arranged to match the limit hole 803;

[0035] It should be noted here that: through the setting of the limit component, when the first measurement plate 101 and the second measurement plate 102 are combined, the limit plate 802 is pulled to slide on the side wall of the T-shaped rod 801. When the pulling distance of the limit plate 802 exceeds the limit rod 804, the limit plate 802 is rotated so that the limit hole 803 coincides with the limit rod 804, and then the pulling of the limit plate 802 is released. At this time, under the action of the spring of the telescopic component, the limit hole 803 will be pushed to sleeve on the side wall of the limit rod 804, thereby limiting the first measurement plate 101 and the second measurement plate 102 after storage under the limiting action of the limit plate 802, thus ensuring the stability of the first measurement plate 101 and the second measurement plate 102 during storage and placement.

[0036] Please refer to Figure 5 , the T-shaped rod 801 in the figure is provided with a telescopic component for telescoping the limit plate 802. The telescopic component includes a second spring 901 sleeved on the side wall of the T-shaped rod 801. One end of the second spring 901 is connected to the limit plate 802, and the other end of the second spring 901 is connected to the measurement auxiliary plate 503 through a rotating ring 902;

[0037] It should be noted here that: through the setting of the telescopic component, it is convenient to drive the limit plate 802 to reset.
