Subsequently, there are many influencing factors when using plumb measurement, and the inclination of the building angle cannot be read when using plumb measurement.

[0004] Therefore, the present application provides a project acceptance verticality detection device to solve the above-mentioned problem. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] Example 1

[0025] This embodiment provides a device for detecting verticality of a project acceptance, such as Figure 1-7As shown, the verticality detection device for project acceptance includes a detection plate 2 and a positioning plate 1 sleeved on the outside of the detection plate 2, the end of the positioning plate 1 is rotatably inserted with a hinged rod 3 fixedly connected to the detection plate 2 through a circular hole, the positioning plate 1 is fixedly connected with an arc ruler 4 located on the same axis as the circular hole, and the hinged rod 3 is fixedly connected with a pointer 5 used in conjunction with the arc ruler 4; through the hinge connection between the detection plate 2 and the positioning plate 1, the detection plate 2 can be rotated 0°-180° on the positioning plate 1, and in the process of the detection plate 2 driving the pointer 5 to rotate axially, through the cooperation of the pointer 5 and the arc ruler 4, the angle value between the detection plate 2 and the positioning plate 1 can be viewed in real time, and then the vertical condition between the base surface and the wall surface of the building can be more clearly seen;

[0026] When in use, first place the positioning plate 1 on the base surface so that the hinged end of the positioning plate 1 contacts the vertical wall surface, and then rotate the detection plate 2 counterclockwise. During the movement of the detection plate 2, the pointer 5 is driven to rotate until the top of the detection plate 2 contacts the wall surface and stops. At this time, it can be seen whether the base surface and the wall surface are in a vertical state by observing the value indicated by the pointer 5 corresponding to the arc scale 4.

[0027] Furthermore, in order to ensure that the detection plate 2 has a self-locking function during the axial rotation on the positioning plate 1: a locking mechanism 6 for axially rotating and locking the hinge rod 3 is provided on the positioning plate 1; the locking mechanism 6 includes a fixed seat 601 fixed on the positioning plate 1, and a locking gear 602 fixedly connected to the hinge rod 3 is rotatably provided inside the fixed seat 601, and a tooth plate 603 meshingly connected to the locking gear 602 is slidably inserted inside the fixed seat 601 through a slide groove, and an elastic member connected to the tooth plate 603 is provided in the slide groove; The elastic member is specifically a fastening spring 605, a limiting groove is provided inside the slide groove, a limiting slide plate 604 fixedly connected to the tooth plate 603 is slidably sleeved in the limiting groove, and the fastening spring 605 is located between the bottom end of the limiting slide plate 604 and the limiting groove; wherein the fastening spring 605 is initially in a state of extrusion force and force storage, and the tooth plate 603 can have a reciprocating motion function through the elastic force of the fastening spring 605, and then the detection plate 2 can have a position locking function during the axial rotation process through the cooperation between the tooth plate 603 and the locking gear 602;

[0028] When in use, as the detection plate 2 drives the articulated rod 3 to rotate, the articulated rod 3 drives the locking gear 602 to rotate. Due to the characteristics of the locking gear 602, the locking gear 602 squeezes the tooth plate 603 to move downward. At this time, the tooth plate 603 drives the limiting slide plate 604 to squeeze the fastening spring 605 to shrink and accumulate force. Under the action of the fastening spring 605, the tooth plate 603 can reciprocate, so that the tooth plate 603 always remains in mesh with the locking gear 602, thereby completing the position locking of the detection plate 2.

[0029] Furthermore, in order to facilitate the removal of the detection plate 2 from the positioning plate 1 , an auxiliary removal groove 201 is provided on one end of the detection plate 2 away from the hinge rod 3 , and a groove 101 corresponding to the auxiliary removal groove 201 is provided on the positioning plate 1 .

[0030] Example 2

[0031] Different from Example 1, (when the base surfaces are not parallel, there will be a problem of large errors in verticality detection), for this reason, the positioning plate 1 is also provided with a horizontal adjustment mechanism 8 for adjusting the water level of the positioning plate 1, and the horizontal adjustment mechanism 8 includes a fixed plate 801 fixedly connected to the bottom end of the positioning plate 1 and a cylindrical level bubble 7 and a threaded sleeve 803 fixedly connected to the side of the positioning plate 1, and an adjusting screw 8031 ​​is threadedly inserted on the threaded sleeve 803, and an adjusting gear 8032 is fixedly sleeved on the top of the adjusting screw 8031. Through the horizontal adjustment mechanism 8, when the base surface is in an inclined state, the positioning plate can be adjusted to a horizontal state to ensure the accuracy of the verticality detection of the wall.

[0032] Furthermore, in order to keep the end of the positioning plate 1 away from the hinged rod 3 stable in adjustment: the side of the positioning plate 1 away from the threaded sleeve 803 is fixedly connected with a guide sleeve 804, the interior of the guide sleeve 804 is slidably inserted with a guide rod 8041, and the bottom end of the guide rod 8041 is fixedly connected with a movable plate 802 rotatably connected to the adjusting screw 8031.

[0033] When the base surface is tilted, when the water bubble in the cylindrical level bubble 7 is close to the threaded sleeve 803, first place the positioning plate 1 on the base surface so that the fixed plate 801 at the bottom of the positioning plate 1 contacts the base surface, and then rotate the adjusting gear 8032 counterclockwise, the adjusting gear 8032 drives the adjusting screw 8031 ​​to rotate counterclockwise, and the adjusting screw 8031 ​​is rotatably connected with the movable plate 802, and then the movable plate 802 moves away from the positioning plate 1. At this time, the water bubble in the cylindrical level bubble 7 close to the threaded sleeve 803 moves toward the cylindrical water bubble. The middle part of the flat bubble 7 moves; when the water bubble in the cylindrical horizontal bubble 7 approaches the hinged rod 3, first, when the positioning plate 1 is placed on the base surface, the fixed plate 801 at the bottom end of the positioning plate 1 contacts the base surface, and then the adjusting gear 8032 is rotated clockwise, and the adjusting gear 8032 drives the adjusting screw 8031 ​​to rotate clockwise, and the adjusting screw 8031 ​​is rotatably connected with the movable plate 802, and then the movable plate 802 will move toward the direction close to the positioning plate 1. At this time, the water bubble on the hinged rod 3 in the cylindrical horizontal bubble 7 moves toward the middle part of the cylindrical horizontal bubble 7.

[0034] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes according to the technical solution and concept of the present application within the technical scope disclosed in the present application, which should be covered by the protection scope of the present application.
