Description

Technical Field

[0001] The invention relates to the technical field of measurement and fixation, in particular to a photogrammetry and fixation device with a stable lens. Background Art

[0002] Photogrammetry is an information science that studies the acquisition, processing, extraction and expression of information through images. Traditional photogrammetry is a science and technology that uses images taken by optical cameras to study and determine the shape, size, properties and relationships of the objects being photographed. It includes the following contents: obtaining images of the objects being studied, theories, methods, equipment and techniques for processing single and multiple images, and how to express the measured results in graphics, images or numbers. When measuring a target, the existing photogrammetry device needs to fix the target to prevent it from falling sideways, but after fixation, it cannot intuitively reflect the length and width of the bottom end surface of the target, and the device cannot be stored, and will take up a large space when idle. Therefore, a photogrammetry fixing device with a stable lens is designed to solve the above-mentioned problems. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a photogrammetry fixing device with a stable lens, which can clamp and fix the target to prevent it from falling sideways. After fixation, the length and width of the target can be intuitively obtained, and the device can be stored when idle to reduce space occupation, thereby effectively solving the problems mentioned in the above background technology.

[0004] In order to solve the above problems, the technical solution adopted by the present invention is:

[0005] A photogrammetric fixing device with a stable lens comprises an operating table, wherein a telescopic arm which can be extended and retracted up and down is provided at the upper end of the operating table, an extension arm is provided at the top end of the telescopic arm, and when the telescopic arm is retracted downward, a structure is formed in which the extension arm flips and slides inwardly of the telescopic arm and is folded downward synchronously with the telescopic arm; a fixed plate is provided at the upper end of the operating table, a plurality of clamping rulers are provided on the fixed plate, and a rotatable turntable is installed at the lower end of the operating table, and when the turntable is rotated, a structure is formed in which the plurality of clamping rulers move inwardly and stop automatically after moving to the top end.

[0006] The present invention has novel structure, ingenious design, simple and convenient operation, and has the following advantages compared with the prior art:

[0007] 1. By placing the object to be measured on the upper end surface of the fixed plate, starting the second motor will cause multiple clamps to move inward synchronously. Each corresponding clamp will automatically stop after contacting the outer surface of the object and clamping it. By observing the position of the measuring mark reaching the corresponding scale bar, the size of the lower end of the object can be intuitively obtained.

[0008] 2. When the device is stored, the first motor is started to shrink the telescopic arm downward, and the corresponding extension arm turns downward along the inner wall of the telescopic arm and slides toward the inner wall of the telescopic arm, so that the device shrinks and reduces the space occupied when stored.

[0009] 3. By pulling the drawer forward, the drawer can slide out and open, and the extension table can be flipped upward to a horizontal position and unfolded for use by the user.

[0010] 4. By pressing the corresponding switch button, starting the third motor will cause the sleeve to rotate in a circle while moving upward or in a spiral trajectory; allowing the camera to perform photogrammetric measurement of the outer surface or upper end face of the object in all directions.

[0032] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0033] like Figure 1-20 As shown, the present invention provides a photogrammetry fixture with a stable lens, comprising an operating table 1, wherein the upper end of the operating table 1 is provided with a telescopic arm that can be extended and retracted up and down, and the top end of the telescopic arm is provided with an extension arm 39, and when the telescopic arm is retracted downward, a structure can be formed in which the extension arm 39 flips and slides inside the telescopic arm and is folded downward synchronously with the telescopic arm; a fixed plate 10 is provided at the upper end of the operating table 1, and a plurality of clamping rulers are provided on the fixed plate 10, and a rotatable turntable 7 is installed at the lower end of the operating table 1, and when the turntable 7 is rotated, a structure can be formed in which the plurality of clamping rulers move inward and stop automatically after moving to the top end.

[0034] like Figure 1-3As shown, the operating table 1 supports and fixes the device; by placing the object to be measured on the fixed disk 10, the multiple clamps can be moved inward when the turntable 7 rotates, and the clamps will automatically stop after moving to the top. When the clamps move to the top, that is, when two corresponding clamps touch the outer surface of the object, it can prevent the clamps from being damaged by excessive clamping force, and after the clamps are fixed to the object, the length and width of the object can be measured intuitively, which saves time and effort and is convenient and quick to use; when the device is idle, the telescopic arm that can be extended up and down is used to extend the telescopic arm downward, and the corresponding extension arm 39 will turn downward along the inner wall of the telescopic arm and slide toward the inner wall of the telescopic arm, so that the device is retracted to it, and the space occupied can be reduced when stored.

A first threaded cylinder 33 is threadedly connected to the outer surface of the first threaded rod 32, and the first threaded cylinder 33 is fixedly connected to the inner wall of the second support arm 30.

[0036] The first support arm 29 and the second support arm 30 are installed and shaped as follows Fig.11 As shown, the second support arm 30 is slidably connected to the inner wall of the first support arm 29, the first threaded cylinder 33 is fixedly connected to the inner wall of the bottom end of the second support arm 30, and the lower end of the outer surface of the first threaded rod 32 is also rotatably connected to a bearing fixing seat, and the first threaded rod 32 can only rotate by being reinforced and limited by the bearing fixing seat; the function of the first motor 31 is to provide rotational force for the first threaded rod 32; the first threaded rod 32 is the prior art and will not be described in detail; by starting the first motor 31, the corresponding first threaded rod 32 will rotate, and the first threaded rod 32 will rotate through the threaded connection with the first threaded cylinder 33. Since the first threaded cylinder 33 cannot rotate, the first threaded cylinder 33 and the second support arm 30 will move downward, thereby causing the telescopic arm to telescope up and down.

[0037] The inner wall of the second support arm 30 is rotatably connected to a long rotating shaft 34, and the long rotating shaft 34 is slidably connected to the inner wall of the first threaded rod 32. The inner wall of the second support arm 30 is also rotatably connected to a second threaded rod 35 that can rotate synchronously with the long rotating shaft 34. The outer surface of the second threaded rod 35 is threadedly connected to a first slider 38 slidably connected to the second support arm 30. One end of the extension arm 39 is hinged on the first slider 38. A fixing pin 40 is fixed to the front side of the upper end of the second support arm 30, and a key groove matching the fixing pin 40 is provided in the middle of the extension arm 39.

At the same time, the rotation of the first threaded rod 32 will drive the long rotating shaft 34 to rotate, and the rotation of the long rotating shaft 34 will drive the first pulley 36, the second pulley 37, and the second threaded rod 35 to rotate synchronously. When the second threaded rod 35 rotates, the first slider 38 will move downward, and the downward movement of the first slider 38 will pull one end of the extension arm 39 to move downward, and the extension arm 39 will slide downward and flip backward under the limitation of the fixing pin 40, and will follow the second support arm 30 to move downward, so that the extension arm 39 slides to the inside of the second support arm 30 and can follow the second support arm 30 to move downward to the bottom, so that the device can be folded, which not only does not take up space but is convenient for storage and convenient for taking the mobile device.

[0041] The inner wall of the slide box 11 is slidably connected with a hollow wedge block 13, and the inner end surface of the hollow wedge block 13 is fixedly connected with a square guide rod 17, and the inner side of the square guide rod 17 passes through the corresponding inner end surface of the slide box 11, and the inner end surface of the square guide rod 17 is fixedly connected with a square gasket 18. The outer surface of the square guide rod 17 is respectively sleeved with a second spring 16, and one end of the second spring 16 is respectively fixedly connected to the inner wall of the slide box 11, and the other end of the second spring 16 is respectively fixedly connected to the corresponding hollow wedge block 13; the first sliding pin 12 passes through the inner wall of the bottom end of the corresponding slide box 11 and is slidably connected to the slide box 11, and the outer surface of the first sliding pin 12 A first spring 15 is respectively sleeved thereon, a second sliding pin 14 is respectively provided at the upper end of the first sliding pin 12, a V-shaped groove matching the corresponding second sliding pin 14 is respectively opened on the inner wall of the hollow wedge block 13, a reset guide rod 22 is respectively fixedly connected to the outer end surface of the hollow wedge block 13, and a reset gasket 20 is respectively fixedly connected to the other end of the reset guide rod 22, and four baffles 21 evenly distributed and matching with the reset gasket 20 are fixedly connected to the outer periphery of the upper end surface of the fixed disk 10; measurement marks 19 are respectively fixedly connected to the two side surfaces of the sliding box 11, and a plurality of groups of scale bars matching with the measurement marks 19 are opened on the upper end surface of the fixed disk 10.

[0042] like Figure 3 , 5 -6, the slide box 11 is installed and shaped as Figure 5-6 As shown, the inner wall of the slide box 11 is provided with a mounting groove, the first sliding pin 12, the first spring 15, etc. are respectively arranged in the mounting groove, the first sliding pin 12 is respectively connected to the inner wall of the slide box 11 for sliding up and down, and the outer surface of the first sliding pin 12 is respectively fixed with a circular gasket matched with the first spring 15, and the first spring 15 exerts a downward force on the circular gasket and the first sliding pin 12, so that the first sliding pin 12 is meshed with the volute toothed disk 9; the upper end surface of the first sliding pin 12 is respectively fixed with a support seat, and the second sliding pin 14 is fixed on the support seat, and the second sliding pin 14 is limited to move up and down; the slide box 11, the first sliding pin 12, the second sliding pin 14, the first spring 15, the second spring 16, the hollow wedge 13, the square guide rod 17, the square gasket 18, the reset guide rod 22, and the baffle 21 are installed and shaped as shown in the figure Figure 5As shown, the hollow wedge blocks 13 are respectively connected to the inner walls of the corresponding slide boxes 11 in a horizontal forward and backward or left and right sliding manner; by placing an object on the upper end surface of the fixed disk 10, when the volute gear disk 9 rotates, the engagement with the first sliding pin 12 will cause multiple slide boxes 11, square guide rods 17, square washers 18, etc. to move synchronously inward or outward. When one of the square washers 18 moves inward to contact the object, the square washers 18 move inward again, which will push the object to move inward, so that the object is pushed to the center position of the fixed disk 10. When the square washers 18 push the object to the center position, the two square washers 18 in the front and back or left and right positions will synchronously contact the object. When the front and back or left and right two square washers 18 synchronously contact the object, the washers 18 continue to move inward. The two corresponding square gaskets 18 will clamp inwardly. At this time, the two corresponding square gaskets 18 will no longer move inwardly after contacting the object, that is, the corresponding square guide rods 17 and hollow wedges 13 will no longer move inwardly. At this time, the turntable 7 continues to rotate, which will cause the corresponding first sliding pin 12 and sliding box 11 to continue to move inwardly. The inward movement of the sliding box 11 will drive the second spring 16 to lengthen. When the first sliding pin 12 moves inwardly, since the second sliding pin 14 is fixed to the first sliding pin 12, the inward movement of the first sliding pin 12 will drive the second sliding pin 14 to move inwardly. When the second sliding pin 14 moves inwardly, it will engage with the V-shaped groove to cause the second sliding pin 14 and the first sliding pin 12 to move upward. The upward movement of the first sliding pin 12 or compresses the first spring 15. When the first sliding pin 12 moves inwardly, the second sliding pin 14 and the first sliding pin 12 will move upward. When the sliding pin 12 moves upward to disengage from the spiral toothed disk 9, the spiral toothed disk 9 continues to rotate and will no longer engage with the corresponding first sliding pin 12 and move inward, that is, at this time, the first sliding pin 12 and the spiral toothed disk 9 are in a state of continuous engagement and disengagement, and the corresponding two square washers 18 have an inward clamping force under the spring force of the second spring 16 and the first spring 15. When the spiral toothed disk 9 continues to rotate, the other two corresponding square washers 18 will also be clamped inwardly synchronously under the same action as the above principle until the first sliding pin 12 is disengaged from the spiral toothed disk 9. Therefore, after the object is clamped and fixed by the clamp ruler, not only can objects of different lengths and widths be limited and clamped, but the center of the object can also be calibrated, and the clamp can The holding force is constant, and the object can be prevented from being damaged by excessive clamping. When all the square gaskets 18 contact and clamp the object, the length and width of the object can be measured intuitively by observing the measuring mark 19 reaching the corresponding position of the scale bar. When it needs to be reset, the spiral toothed disk 9 is reversed by starting the second motor 4. When the spiral toothed disk 9 rotates again, that is, reverses, the first sliding pin 12 will enter the gap teeth of the spiral toothed disk 9 again under the elastic force of the first spring 15 when it meets the gap teeth of the spiral toothed disk 9, so that the first sliding pin 12 is meshed with the spiral toothed disk 9 again, so that the slide box 11 and the like move outward synchronously. When it moves outward until all the reset gaskets 20 contact the baffle 21, the reset can be achieved at this time. The principle is the same and will not be repeated.
