[0002] Currently in the engineering cost industry, when workers are conducting measurement work on drawings, they need to frequently use various measuring devices such as measuring rulers, compasses, and protractors to complete operations such as drawing lines, measuring line lengths, drawing circles, and measuring angles on the drawings. The process is tedious and complicated.

[0003] In practice, there are still many inconveniences. When measuring drawings, there is the problem of the drawings not being able to be laid flat, especially when measuring some large or complex drawings. This problem is more prominent, which not only affects the accuracy of the measurement, but also increases the difficulty and time cost of the measurement. In addition, some existing measuring devices often do not have the functions of height adjustment, angle adjustment and effective limit of the drawings, which cannot meet the needs of the staff of different heights, and are not conducive to comprehensive observation and accurate measurement of the drawings from different perspectives, resulting in low measurement efficiency and poor observation comfort for the staff.

[0004] Based on this, an engineering drawing measurement device is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation

[0020] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0021] Reference Figures 1-3 A drawing measurement device for engineering applications includes a support frame 101. The lower end of the support frame 101 is symmetrically provided with support feet 103. A worktable 102 is mounted on the upper end of the support frame 101 via a lifting mechanism 200. An adjustment platform 105 is provided above the worktable 102. The adjustment platform 105 is rotatably mounted on the worktable 102 via a rotating mechanism 300. A lifting block 106 is provided at the middle position of the upper end of the adjustment platform 105. A flat surface 104 for placing drawings is provided on the lifting block 106. A positioning mechanism 400 for limiting the position of the drawings is provided on the lifting block 106.

[0022] The lifting mechanism 200 is used to adjust the height of the drawing to facilitate measurement by people of different heights. The positioning mechanism 400 is used to press and limit the edges and corners of the drawing to prevent the edges from warping and making it difficult to observe. The rotating mechanism 300 is used to allow staff to adjust the angle of the drawing for easier viewing. After the angle is adjusted, it is convenient to observe from different perspectives, which improves the efficiency of measurement and the comfort of observation.

[0023] Reference Figures 1-3The lifting mechanism 200 includes a motor 201, a screw rod 202, a guide rod 203, an adjusting support base 204, and an adjusting column 205. The adjusting column 205 is slidably mounted on the support frame 101. The adjusting support base 204 is fixedly installed between the support frames 101. The motor 201 is fixedly installed on the side wall of the adjusting column 205 through a mounting plate. The output end of the motor 201 is connected to the screw rod 202. The other end of the screw rod 202 is rotatably engaged with the adjusting support base 204. The adjusting support base 204 has a thread that engages with the screw rod 202. The other end of the adjusting support base 204 is provided with a guide rod 203 that is symmetrically arranged with the screw rod 202. The other end of the guide rod 203 is connected to the worktable 102.

[0024] The starting motor 201 drives the screw rod 202 to rotate. The rotation of the screw rod 202 can cooperate with the adjusting support seat 204 to make the adjusting column 205 slide up and down on the support frame 101, thereby adjusting the height of the drawing and making it convenient for people of different heights to take measurements.

[0025] Reference Figures 1-2 The rotating mechanism 300 includes a mounting base 301, a slot 302, and a rotating rod 303. The mounting base 301 is symmetrically arranged on the worktable 102. The mounting base 301 is provided with a plurality of slots 302. The rotating rod 303 is rotatably arranged on the side wall of the adjusting table 105 and engages with the slots 302. One end of the adjusting table 105 and one end of the mounting base 301 are rotatably engaged through a rotating shaft.

[0026] The angle of the rotating adjustment table 105 can be rotated and fixed by the rotating rod 303 being locked in different slots 302, which enables the adjustment of the angle for drawing observation and measurement, thus improving work efficiency.

[0027] Reference Figures 2-3 The positioning mechanism 400 includes a slide rail 401, a sliding frame 402, a rotary knob 403, a lead screw 404, and a positioning foot 405. The lifting block 106 is symmetrically provided with slide rails 401, and the slide frames 402 are symmetrically slidably provided on the slide rails 401. A gap is provided between the slide frames 402 for the flat table 104 to pass through. The positioning foot 405 is slidably provided in the gap. One end of the lead screw 404 passes through the side wall of the slide frame 402 and rotates with the positioning foot 405. The other end of the lead screw 404 is connected to the rotary knob 403. The slide frame 402 is provided with a thread that mates with the lead screw 404. The positioning foot 405 slides with the inner wall of the slide frame 402.

[0028] Slide the sliding frame 402 to the appropriate position and rotate the rotary knob 403 to drive the lead screw 404 to rotate, so that the positioning presser foot 405 can move up and down and limit and clamp the corners of the drawing.

[0029] Reference Figure 2 The length of the rotating rod 303 is greater than the length of the end of the adjusting table 105 away from the rotating shaft.

[0030] This allows the rotating rod 303 to rotate to a position horizontal with the adjusting table 105.

[0031] Reference Figure 3 The flat platform 104 has a circular pad at the lower center that is connected to the lifting block 106. The height of the pad is greater than the height of a single side wall of the sliding frame 402 and less than the width of the gap.

[0032] This facilitates the sliding frame 402 to slide through the tiling table 104 and wrap around the drawing.

[0033] Working principle: Place the drawing on the flat table 104, slide the sliding frame 402 to the appropriate position, and rotate the rotary knob 403 to drive the lead screw 404 to rotate, so that the positioning pressure foot 405 can move up and down and limit the corners of the drawing. Rotate the adjustment table 105 and lock it into different slots 302 through the rotating rod 303 to rotate and fix the angle of the adjustment table 105. This enables the observation and measurement of the drawing angle to be adjusted, improving work efficiency. Start the motor 201 to drive the screw rod 202 to rotate. The rotation of the screw rod 202 can cooperate with the adjustment support 204 to make the adjustment column 205 slide up and down on the support frame 101, so as to adjust the height of the drawing and facilitate measurement for people of different heights.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
