Specific implementation mode

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

[0022] Please refer to Figures 1-5 As shown, a device for detecting internal and external corners includes a measurement patch 1. A through groove 2 is opened on the surface of the measurement patch 1. A rotating rod 3 is rotatably arranged on the surface of the through groove 2. An extension block 4 is fixed on the surface of the rotating rod 3. The other end of the surface of the extension block 4 is fixed with a handle 5. An adjustment mechanism 7 for restricting the angle of the rotating rod 3 is arranged on the surface of the measurement patch 1. A plurality of reset mechanisms 8 are arranged on the surface of the measurement patch 1. A plurality of measurement mechanisms 9 for measuring internal and external corners are arranged on the surface of the reset mechanism 8. When the present utility model is in use, the user can use the adjustment mechanism 7 according to the detection environment. Under the action of the adjustment mechanism 7, the position of the handle 5 on the surface of the measurement patch 1 can be adjusted, so that the handle 5 is in different positions, and then the measurement patch 1 shows different detection situations, which is convenient for the user to take it. And under the comparison of a plurality of measurement mechanisms 9, the flatness of the wall surface can be measured as a whole, and under the action of the reset mechanism 8, the practicability of the measurement mechanism 9 is improved.

[0023] A horizontal bubble is arranged on the top of the measurement patch 1.

[0024] The adjusting mechanism 7 includes a limiting rod 73 that slides within the inner cavity of the measuring patch 1 and a plug 74 fixed to one end of the rotating rod 3 for cooperating with the limiting rod 73. The limiting rod 73 is a prism. One end of the limiting rod 73 is fixed with a force-receiving head 71. The surface of the force-receiving head 71 is fixed with a connecting spring 72. The other end of the connecting spring 72 is fixed to the surface of the measuring patch 1. In this embodiment, through the arrangement of the force-receiving head 71, the connecting spring 72, the limiting rod 73, and the plug 74, after the limiting rod 73 and the plug 74 are connected, under the action of the limiting rod 73, the angles of the extension block 4 and the rotating rod 3 can be limited. When it is necessary to switch the usage state of the measuring patch 1, the staff pulls up the force-receiving head 71, and the limiting rod 73 and the plug 74 can be separated.

[0025] The reset mechanism 8 includes a plurality of sleeves 81 fixed to the surface of the measuring patch 1. A fixed block 82 is fixed inside the inner cavity of the sleeve 81. A sliding rod 83 is slidably arranged inside the inner cavity of the fixed block 82. On both sides of the surface of the sliding rod 83, a reset spring 84 is sleeved. One end of the two reset springs 84 is fixed to the surface of the fixed block 82. In this embodiment, through the arrangement of the sleeve 81, the fixed block 82, the sliding rod 83, and the reset spring 84, under the action of the sleeve 81, the position of the fixed block 82 is limited. Under the action of the reset spring 84, the position of the sliding rod 83 sliding inside the inner cavity of the fixed block 82 is limited.

[0026] The measuring mechanism 9 includes a connecting block 91 fixed to one end of the sliding rod 83. The other end of the reset spring 84 is fixed to the surface of the connecting block 91. A color rod 92 is fixed to the surface of the connecting block 91. One end of the surface of the color rod 92 is fixed with a connecting rod 93. The other end of the connecting rod 93 is fixed with a friction head 94. In this embodiment, through the arrangement of the connecting block 91, the color rod 92, the connecting rod 93, and the friction head 94, after the friction head 94 fits against the wall surface and drives the connecting rod 93 and the color rod 92 to move, it can, under the reminder of the color rod 92, inform the staff of the situation here.

[0027] The shape of the friction head 94 is spherical, and the material is wear-resistant steel. In this embodiment, through this arrangement, the friction between the friction head 94 and the wall surface is reduced, and under the action of the wear-resistant steel, the service life of the friction head 94 is improved.

[0028] A plurality of anti-slip ridges 6 are annularly arrayed on the surface of the handle 5. The anti-slip ridges 6 are made of rubber. In this embodiment, through the arrangement of the anti-slip ridges 6, the friction between the handle 5 and the staff's hand is increased, facilitating the staff to use the handle 5.

[0029] Working principle: When it is necessary to test the internal and external corners of the wall surface, the staff can reasonably use the adjusting mechanism 7 according to the situation of the working area. Under the action of the force-bearing head 71, the limit rod 73 and the plug 74 can be separated, so that the handle 5 drives the rotating rod 3 to rotate. When the handle 5 is inside the measuring patch 1, the measuring patch 1 is used to measure the existence of the internal corner. When the handle 5 is outside the measuring patch 1, the measuring patch 1 is used to measure the existence of the external corner. During the test, the staff can attach one side of the measuring patch 1 to the wall surface, and under the action of the horizontal bubble, it is reminded whether the angle of the measuring patch 1 meets the specifications. A number of friction heads 94 on one side of the measuring patch 1 can first be attached to the wall surface, and when the friction heads 94 contact the wall surface, the connecting rod 93 drives the color rod 92 to slide in the inner cavity of the sleeve 81, so that the other connecting rod 93 drives the friction head 94 to protrude. At this time, the staff can observe whether the wall surface at this place is flat through the color rod 92, and under the action of the measuring mechanism 9 and the reset mechanism 8 on the other side, an evaluation can be made on the overall situation at this place. Since multiple friction heads 94 are provided on one side, the situation at this place can also be measured using the principle of two points determining a straight line. For example, if the moving distances of the color rods 92 in the same row are different, the displayed colors will be different.
