Description

Technical Field

[0001] This utility model relates to the field of total station technology, specifically to a total station reflector for monitoring building deformation that is easy to disassemble. Background Technology

[0002] A total station is a surveying instrument that integrates angle and distance measurement. A total station reflector is a reflective element used in conjunction with the total station for distance measurement and deformation monitoring. It typically consists of numerous microprisms with total internal reflection arranged according to a specific pattern, controlling the path of light entering and exiting.

[0003] A Chinese patent (publication number CN202322578909.2) discloses a movable total station reflector bracket, including a support plate, a movable device, a pole, and a limiting device. The movable device can easily adjust the angle of the reflector to adapt to different measurement needs, and the limiting device can limit the angle range of the reflector to ensure the flexibility of the reflector during use. It is easy to use and can adjust the horizontal and vertical directions of the reflector according to the observation needs, and also protects the reflector.

[0004] However, when using the aforementioned movable total station reflector bracket, the operator needs to repeatedly turn the limiting device to adjust the reflector. After the reflector moves to the appropriate angle, the limiting device needs to be tightened again to fix the reflector. The operation steps of turning the limiting device are cumbersome, which reduces the adjustment efficiency of the reflector.

[0005] To address these issues, we designed a removable reflector for a total station used for monitoring building deformation. Utility Model Content

[0006] The purpose of this invention is to provide a total station reflector for building deformation monitoring that is easy to disassemble, so as to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides a removable reflector for a total station used for monitoring building deformation. The reflector includes a pole, an adjusting block movably mounted on the outer side of the pole, a reflector mounting plate fixedly mounted on one side of the adjusting block, a first mounting groove formed on the inner side of the adjusting block, a telescopic spring fixedly connected to one side of the inner wall of the first mounting groove, a movable plate fixedly connected to the other end of the telescopic spring, the movable plate movably disposed inside the first mounting groove, a rod fixedly connected to the side of the movable plate away from the telescopic spring, and an insertion hole formed on one side of the pole, into which the rod is inserted.

[0008] Furthermore, a protective shell is snapped onto the side of the reflector mounting plate away from the adjusting block, a snap-fit ​​box is fixedly connected to one side of the protective shell, a mounting box is fixedly connected to one side of the reflector mounting plate, a moving block is slidably connected inside the mounting box, a compression spring is fixedly connected to one side of the moving block, the other end of the compression spring is fixedly connected to one side of the inner wall of the mounting box, and a snap-fit ​​block is fixedly connected to the end of the moving block away from the compression spring, and the snap-fit ​​block snaps into the snap-fit ​​box.

[0009] Furthermore, a lever is fixedly connected to one side of the movable plate, and a guide groove is provided on one side of the adjusting block, with the lever slidably inserted into the inside of the guide groove.

[0010] Furthermore, there are two insertion rods, which are symmetrically arranged on both sides of the adjusting block with the vertical axis of the upright as the center.

[0011] Furthermore, a through groove is provided at the center of the adjustment block, and the upright is inserted into the inside of the through groove.

[0012] Furthermore, the protective shell is an acrylic sheet protective shell.

[0013] Furthermore, the shape of the snap-fit ​​block is set to trapezoidal.

[0014] Furthermore, the inside of the snap-fit ​​box is provided with a snap-fit ​​slot, and the snap-fit ​​block is inserted into the inside of the snap-fit ​​slot.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. Hold the two ends of the adjusting block with both hands and move the blocks apart with your fingers. The blocks will move away from each other and the moving plate will move the insert rod away from the insertion hole. At this time, the adjusting block and the reflector mounting plate can move vertically along the pole. After the adjusting block is moved to the appropriate position, release the blocks. The telescopic spring will return to its original position and the moving plate will move closer to the pole. The insert rod will be inserted into the appropriate insertion hole, and the reflector mounting plate will be fixed. 2. Align the four edges of the protective shell with the reflector mounting plate. As the protective shell moves closer to the reflector mounting plate, the snap-fit ​​box on one side of the protective shell moves synchronously with the protective shell. The snap-fit ​​box contacts the snap-fit ​​block, and the snap-fit ​​block is squeezed back into the mounting box by the snap-fit ​​box. The compression spring is squeezed synchronously by the moving block. The snap-fit ​​box moves until it is aligned with the mounting box, the compression spring returns to its original position, and the snap-fit ​​block is inserted into the snap-fit ​​groove, so that the reflector mounting plate and the protective shell are snapped and fixed.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5 This utility model provides a technical solution: it includes a pole 1, an adjusting block 2 movably installed on the outer side of the pole 1, a reflective sheet mounting plate 3 fixedly installed on one side of the adjusting block 2, a first mounting groove 6 opened on one side of the inner side of the adjusting block 2, a telescopic spring 7 fixedly connected to one side of the inner wall of the first mounting groove 6, a movable plate 8 fixedly connected to the other end of the telescopic spring 7, the movable plate 8 movably disposed inside the first mounting groove 6, a plug rod 10 fixedly connected to the side of the movable plate 8 away from the telescopic spring 7, an insertion hole 17 opened on one side of the pole 1, the plug rod 10 inserted into the insertion hole 17, a lever 9 fixedly connected to one side of the movable plate 8, a guide groove opened on one side of the adjusting block 2, the lever 9 slidably inserted into the guide groove, a through groove 5 opened at the center of the inner side of the adjusting block 2, and the pole 1 inserted into the through groove 5.

[0020] It should be noted that a fixed base plate is also fitted to the tail of the upright 1. When the bottom of the upright 1 is inserted into the ground until the fixed base plate contacts the ground, the upright 1 can be fixed. The fixed base plate helps to improve the stability of the upright 1 fixed on the ground.

[0021] In practice, the user can install the reflector on the side of the reflector mounting plate 3 away from the adjusting block 2, then fasten the protective shell 4, insert the tail of the pole 1 into the ground, and then monitor the deformation of the building using a total station. When it is necessary to adjust the height of the reflector, the user can hold both ends of the adjusting block 2 with both hands and move the lever 9 with their fingers to move the two levers 9 away from each other. When the lever 9 moves, the lever 9 drives the insertion rod 10 to move through the moving plate 8. The insertion rod 10 inserted into the insertion hole 17 moves away from the insertion hole 17. At this time, the adjusting block 2 and the reflector mounting plate 3 can move vertically along the pole 1. After the adjusting block 2 is moved to the appropriate position, the user releases the hands that moved the lever 9. Under the push of the return of the telescopic spring 7, the moving plate 8 moves towards the pole 1, and the insertion rod 10 is inserted into the appropriate insertion hole 17, thus fixing the reflector mounting plate 3.

[0022] See Figure 2 A protective shell 4 is snapped onto the side of the reflector mounting plate 3 away from the adjusting block 2. A snap-fit ​​box 12 is fixedly connected to one side of the protective shell 4. A mounting box 11 is fixedly connected to one side of the reflector mounting plate 3. A moving block 15 is slidably connected inside the mounting box 11. A compression spring 14 is fixedly connected to one side of the moving block 15. The other end of the compression spring 14 is fixedly connected to one side of the inner wall of the mounting box 11. A snap-fit ​​block 16 is fixedly connected to the end of the moving block 15 away from the compression spring 14. The snap-fit ​​block 16 snaps into the snap-fit ​​box 12. The protective shell 4 is an acrylic sheet protective shell.

[0023] In practice, when the reflector is in use, the protective shell 4 can be snapped onto one side of the reflector mounting plate 3 to protect the reflector on the reflector mounting plate 3. The four edges of the protective shell 4 are aligned with the reflector mounting plate 3. When the protective shell 4 moves closer to the reflector mounting plate 3, the snap-fit ​​box 12 on one side of the protective shell 4 moves synchronously with the protective shell 4. The snap-fit ​​box 12 abuts against the snap-fit ​​block 16. The snap-fit ​​block 16 is squeezed back into the mounting box 11 by the snap-fit ​​box 12. The compression spring 14 is simultaneously squeezed by the moving block 15. When the snap-fit ​​box 12 moves to be aligned with the mounting box 11, the squeezing force on the snap-fit ​​block 16 disappears, the compression spring 14 returns to its original position, and the snap-fit ​​block 16 is inserted into the snap-fit ​​groove 13, so that the reflector mounting plate 3 and the protective shell 4 are snapped and fixed.

[0024] See Figure 3 There are two insertion rods 10, which are symmetrically arranged on both sides of the adjusting block 2 with the vertical axis of the upright rod 1 as the center.

[0025] By providing multiple insertion holes 17 at equal intervals on the outer side of the upright 1, two symmetrically arranged insertion rods 10 can be inserted into the interior of the upright 1 from both sides of the upright 1, i.e., the two ends of the insertion holes 17, which facilitates the improvement of the stability of the adjusting block 2 fixed on the outer side of the upright 1.

[0026] See Figure 5 The snap-fit ​​block 16 is trapezoidal in shape, and the snap-fit ​​box 12 has a snap-fit ​​groove 13 inside, into which the snap-fit ​​block 16 is inserted.

[0027] By setting the cross-sectional shape of the snap-fit ​​block 16 to a trapezoidal shape, when the protective shell 4 approaches the reflector mounting plate 3, the bottom of the snap-fit ​​box 12 first abuts against the inclined surface of the snap-fit ​​block 16, which makes it easier for the snap-fit ​​block 16 to be retracted into the interior of the mounting box 11 under force.

[0028] Working principle: When using the device, the user can install the reflector on the side of the reflector mounting plate 3 away from the adjusting block 2, then put on the protective shell 4, insert the tail of the pole 1 into the ground, and then monitor the deformation of the building through the total station. When it is necessary to adjust the height of the reflector, the user can hold the two ends of the adjusting block 2 with both hands and move the lever 9 with their fingers to make the two levers 9 move away from each other. When the lever 9 moves, the lever 9 drives the insertion rod 10 to move through the moving plate 8. The insertion rod 10 inserted into the insertion hole 17 moves away from the insertion hole 17. At this time, the adjusting block 2 and the reflector mounting plate 3 can move vertically along the pole 1. After the adjusting block 2 is moved to the appropriate position, the user releases the hands that moved the lever 9. Under the push of the return of the telescopic spring 7, the moving plate 8 moves towards the pole 1, and the insertion rod 10 is inserted into the appropriate insertion hole 17, which can fix the reflector mounting plate 3. When the reflector is in use, the reflector can be protected by snapping the protective shell 4 onto one side of the reflector mounting plate 3. The four edges of the protective shell 4 are aligned with the reflector mounting plate 3. When the protective shell 4 moves closer to the reflector mounting plate 3, the snap-fit ​​box 12 on one side of the protective shell 4 moves synchronously with the protective shell 4. The snap-fit ​​box 12 abuts against the snap-fit ​​block 16. The snap-fit ​​block 16 is squeezed back into the mounting box 11 by the snap-fit ​​box 12. The compression spring 14 is simultaneously squeezed by the moving block 15. When the snap-fit ​​box 12 moves to be aligned with the mounting box 11, the squeezing force on the snap-fit ​​block 16 disappears, the compression spring 14 returns to its original position, and the snap-fit ​​block 16 is inserted into the snap-fit ​​groove 13, so that the reflector mounting plate 3 and the protective shell 4 are snapped and fixed.

[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
