[0002] In the fine operations of building construction and interior decoration, the verticality and flatness of the door frame are key elements to measure the fineness and durability of the project. As a transitional structure connecting the interior and the exterior, the verticality of the door frame not only affects the smoothness and sealing performance of the door leaf, but also directly impacts the aesthetics and use safety of the overall decoration. Therefore, accurately and efficiently detecting the verticality of the door frame is crucial for ensuring the project quality.

[0003] However, the traditional detection methods commonly used in the current industry, such as manual measurement using tools like spirit levels and plumb lines, have many limitations. These methods not only require the measurer to have high professional skills and experience, but also the measurement process is easily interfered by the external environment (such as environmental brightness), resulting in inaccurate and unstable measurement results. In addition, the traditional methods can often only measure a specific position of the door frame and cannot comprehensively evaluate the overall verticality and flatness of the door frame, making it difficult to meet the requirements of modern building construction for efficient and comprehensive quality monitoring.

[0020] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where like or similar reference numerals denote like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation of the present utility model. On the contrary, the embodiments of the present utility model include all changes, modifications and equivalents falling within the spirit and scope of the appended claims.

[0021] The doorframe perpendicularity detection device of the embodiments of the present utility model will be described below in conjunction with the accompanying drawings.

[0022] As Figures 1 to 4 shown, the doorframe perpendicularity detection device of the embodiments of the present utility model may include an upper positioning block 10, an upper hinge assembly 20, a telescopic rod 30, a lower positioning block 40, a lower hinge assembly 50, and a plumb bob 60.

[0023] Among them, the upper positioning block 10 is hinged to the top end of the telescopic rod 30 through the upper hinge assembly 20, and the lower positioning block 40 is hinged to the bottom end of the telescopic rod 30 through the lower hinge assembly 50.

[0024] It should be noted that the telescopic rod 30 can be a manually telescopic structure, and the telescopic rod 30 is a straight rod. The shortest length and the longest length after the telescopic rod 30 is telescoped are selected according to actual needs and will not be elaborated here.

[0025] The upper hinge assembly 20 includes a hinge shaft 22 and two side plates 21. The two side plates 21 in the upper hinge assembly 20 are symmetrically installed on the upper positioning block 10, and the hinge shaft 22 in the upper hinge assembly 20 is installed between the corresponding two side plates 21.

[0026] It should be noted that the upper hinge assembly 20 and the lower hinge assembly 50 have the same structure. The two side plates 21 in the lower hinge assembly 50 are symmetrically installed on the lower positioning block 40, and the hinge shaft 22 in the lower hinge assembly 50 is installed between the corresponding two side plates 21.

[0027] The hinge shaft 22 slidably penetrates through the telescopic rod 30, so that the telescopic rod 30 can rotate around the hinge shaft 22.

[0028] It should be noted that the hinge shaft 22 in the upper hinge assembly 20 and the hinge shaft 22 in the lower hinge assembly 50 are arranged in parallel.

[0029] The plumb bob 60 is pivotally connected to any one of the side plates 21 in the upper hinge assembly 20, and the plumb bob 60 can rotate around the hinge shaft 22 in the upper hinge assembly 20.

[0030] It should be noted that the plumb bob 60 has a certain mass, so that when the upper hinge assembly 20 as a whole tilts, the plumb bob 60 can maintain a vertical state under the action of gravity. The specific mass of the plumb bob 60 is selected according to actual usage requirements and will not be elaborated here.

[0031] It should be noted that the side surface of the upper positioning block 10 is perpendicular to the lower surface; the side edge of the lower positioning block 40 is perpendicular to the upper surface.

[0032] Specifically, during the actual operation, the relevant personnel fix the upper positioning block 10 on the door frame without moving it as a measurement reference point, adjust the length of the telescopic rod 30 to adapt to the height of the door frame to be measured; place the lower positioning block 40 at the bottom of the door frame or the part to be measured, and measure the angle between the plumb bob 60 and the telescopic rod 30 (using tools such as a protractor) to determine whether the door frame is vertical; at the same time, the position of the lower positioning block 40 can be changed to measure the perpendicularity between different positions on the door frame and the measurement reference point. When monitoring the perpendicularity of different positions, the position of the plumb bob 60 remains fixed and the plumb bob 60 does not swing. There is no need to wait for the plumb bob 60 to stabilize every time the detection position is changed.

[0033] It can be understood that by measuring the perpendicularity between different positions on the door frame and the measurement reference point, it is possible to detect whether the surface of the door frame is flat. When the difference in the inclination angles (a range of inclination angle differences can be set as the qualified range) between different positions on the door frame and the measurement reference point is small, it indicates that the surface of the door frame is relatively flat; when the difference in the inclination angles between different positions on the door frame and the measurement reference point is large, it indicates that the surface of the door frame is not flat enough.

[0034] Furthermore, in an embodiment of the present utility model, as Figure 2 shown, two screws 11 are installed on both sides of the upper positioning block 10. A clamping plate 12 is slidably arranged on the two screws 11 on the same side. The clamping plate 12 extends out of the upper positioning block 10. The clamping plates 12 on both sides of the upper positioning block 10 are arranged oppositely, and the clamping plate 12 is used to clamp the door frame.

[0035] A nut 13 is threadedly connected to the screw 11. The nut 13 is located on the side of the clamping plate 12 away from the upper positioning block 10, and the nut 13 is used to limit the clamping plate 12.

[0036] It should be noted that anti-slip layers can be provided on the opposite surfaces of the two clamping plates 12.

[0037] It should be noted that the screw 11 and the hinge shaft 22 are arranged in parallel.

[0038] It can be understood that when placing the upper positioning block 10 at the position on the door frame that needs to be measured, rotate the nut 13 to make the clamping plate 12 clamp the door frame, and adjust the clamping force as needed to ensure that the device is firmly fixed on the door frame.

[0039] By setting the clamping plate 12, the upper positioning block 10 can be clamped more firmly on the door frame, improving the stability of measurement, being able to adapt to door frames of different widths and shapes, and enhancing the adaptability of the device.

[0040] In an embodiment of the present utility model, as Figure 4 shown, scale lines may be provided on the side wall at the top end of the telescopic rod 30, and the scale lines correspond to the position of the plumb bob 60.

[0041] In an embodiment of the present utility model, as Figure 1 and Figure 4 shown, a laser 61 is installed at the bottom end of the plumb bob 60, and the laser emission port of the laser 61 faces vertically downward.

[0042] Furthermore, in an embodiment of the present utility model, as Figure 1 shown, a reflector 70 is provided on the lower hinge assembly 50, and the reflector 70 is located directly below the plumb bob 60.

[0043] The reflector 70 and the laser 61 are located on the same side of the telescopic rod 30, and the mirror surface of the reflector 70 faces the laser 61.

[0044] It should be noted that the reflector 70 is installed on the top surface of the side plate 21 in the lower hinge assembly 50, and the reflector 70 is a plane mirror, and the laser beam emitted by the laser 61 can irradiate on the reflector 70.

[0045] It should be noted that the reflector 70 and the telescopic rod 30 are arranged staggeredly.

[0046] It can be understood that the laser 61 installed at the bottom end of the plumb bob 60 can emit a vertically downward laser beam, enabling relevant personnel to more clearly see the vertical state of the plumb bob 60, and being able to judge the perpendicularity of the door frame even in low light or when the line of sight is blocked; by setting the reflector 70 on the lower hinge assembly 50 and using the principle of light reflection, when the door frame is tilted, there will be a reflection angle when the laser emitted by the laser 61 irradiates on the reflector 70, and the larger the reflection angle, the greater the tilt angle of the door frame, further enhancing the visibility and accuracy of measurement.

[0047] In summary, the door frame perpendicularity detection device in the embodiment of the present utility model can accurately detect multiple positions of the door frame, and thus comprehensively evaluate the perpendicularity and flatness of the overall door frame.
