Description

Technical Field

[0001] The invention relates to the technical field of auxiliary brackets, in particular to a portable laser rangefinder bracket. Background Art

[0002] A laser rangefinder is a measuring tool that uses laser technology to measure distance. This instrument measures the distance by emitting a laser beam to a target and calculating the time it takes for the laser beam to be reflected back. Laser rangefinders are widely used in engineering surveying, construction, topographic surveying, forestry, geological exploration, sports and other fields. Compared with traditional measuring tools, laser rangefinders have the advantages of fast measurement speed, high accuracy and easy operation.

[0003] When using a laser rangefinder to measure distance, ensuring the stability of the instrument is crucial to obtaining accurate measurement results. Since the laser rangefinder determines the distance by emitting laser light and calculating the time it takes for it to reflect back, any shaking in the measuring direction may cause measurement errors. Usually, the operator will use a handheld rangefinder to perform quick measurements, but this method is difficult to keep the rangefinder stable, which may affect the accuracy of the measurement results. Therefore, in order to improve the measurement accuracy, in the prior art, surveyors also use a tripod for auxiliary measurement.

[0004] However, when using a tripod, surveyors need to frequently adjust the angle between the rangefinder and the ground when measuring targets at different heights or distances. Existing laser rangefinders are usually fixed on the top of the tripod, so when adjusting the angle, surveyors need to adjust the entire tripod, which is a cumbersome and time-consuming process that reduces work efficiency. Summary of the invention

[0005] The embodiment of the present application provides a portable laser rangefinder bracket to solve the technical problem of inconvenient angle adjustment of the laser rangefinder in the prior art, thereby improving work efficiency.

[0006] In order to solve the above technical problems, the present invention adopts the following technical scheme: a portable laser rangefinder bracket comprises a tripod, a movable frame is horizontally rotatably mounted on the upper end of the tripod, the bottom of the movable frame is rotatably mounted on the upper end of the tripod, two vertical frames are arranged on the upper part of the movable frame, the top ends of the vertical frames are provided with threaded holes, a fixing groove for installing the laser rangefinder is arranged between the two vertical frames, studs A and studs B with the same rotation direction are horizontally fixed on both sides of the fixing groove, wherein stud A passes through the threaded hole at the top end of the movable frame and is tightened by adjusting nut A, and stud B passes through the threaded hole at the top end of the movable frame and is tightened by adjusting nut B.

[0007] Stud A and stud B pass through the threaded holes on the top of the movable frame and are tightened by adjusting nuts A and B respectively. When the fixing slot needs to be flipped, first loosen the adjusting nut A or adjusting nut B, then flip the fixing slot to the desired angle, and finally tighten the adjusting nut A and adjusting nut B to fix the fixing slot on the movable frame, thereby realizing the adjustment of the laser rangefinder in the vertical direction; at the same time, the movable frame is rotatably installed on the upper end of the tripod, which can realize the adjustment of the laser rangefinder in the horizontal angle, thereby solving the technical problem of inconvenient angle adjustment of the laser rangefinder in the prior art.

[0008] Furthermore, a stud C is vertically fixed to the bottom of the movable frame, and the stud C cooperates with the top thread of the tripod. The outer periphery of the stud C is also cooperated with an adjusting nut C; after the adjusting nut C is tightened, the stud C can be pressed to prevent the movable frame from continuing to rotate. The stud C and the adjusting nut C are used together to realize the horizontal rotation and fixation of the movable frame relative to the tripod.

[0009] Furthermore, the fixing groove includes a U-shaped base and two clamping plates located in the U-shaped base, and the two clamping plates are vertically arranged and respectively connected to the two inner walls of the U-shaped base through springs; thereby, the laser rangefinder can be fixed in the fixing groove through the springs.

[0010] Furthermore, a slide rail is provided at the bottom of the U-shaped base, and a slide groove is provided at the bottom of the two clamping plates, and the slide groove cooperates with the slide rail; the cooperation between the slide rail and the slide groove can prevent the clamping plate from shaking when the laser rangefinder is installed, thereby maintaining the stability of the laser rangefinder.

[0011] Furthermore, the tripod includes a central axis and legs supported on the periphery of the central axis, a sliding sleeve capable of moving up and down is embedded in the periphery of the central axis, and a connecting rod is hinged between the sliding sleeve and the legs.

[0012] Furthermore, the central axis includes a fixed rod and a telescopic rod that can be telescoped relative to the fixed rod, and a scale is provided on the outer circumference of the telescopic rod.

[0013] Furthermore, a fixing plate is fixed on the outer periphery of the fixing rod, the fixing plate is hinged to the upper end of the frame leg through a hinge support, and a level is also installed on the fixing plate.

[0014] Furthermore, the frame leg includes a sleeve and a support leg capable of extending and retracting relative to the sleeve.

[0015] It can be seen from the above technical solutions that the present invention has at least the following technical effects or advantages: Stud A and stud B pass through the threaded holes on the top of the movable frame and are tightened by adjusting nuts A and B respectively. When the fixing slot needs to be flipped, first loosen the adjusting nut A or adjusting nut B, then flip the fixing slot to the desired angle, and finally tighten the adjusting nut A and adjusting nut B to fix the fixing slot on the movable frame, thereby realizing the adjustment of the laser rangefinder in the vertical direction; at the same time, the movable frame is rotatably installed on the upper end of the tripod, which can realize the adjustment of the laser rangefinder in the horizontal angle, thereby solving the technical problem of inconvenient angle adjustment of the laser rangefinder in the prior art.

DETAILED DESCRIPTION

[0018] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0019] The invention discloses a portable laser rangefinder bracket, such as Figure 1 As shown, it comprises a tripod 1, a movable frame 2 and a fixing slot 3 installed inside the movable frame 2. The movable frame 2 is installed on the top of the tripod and can rotate relative to the tripod 1, and the fixing slot 3 is installed on the upper part of the movable frame 2 and can flip relative to the movable frame 2.

[0020] like Figure 1 , Figure 2 As shown, the tripod 1 includes a central axis 4 and legs 5 supported on the periphery of the central axis 4, wherein the central axis 4 includes a fixed rod 6 and a telescopic rod 7 embedded in the fixed rod 6, and the telescopic rod 7 can be extended and retracted relative to the fixed rod 6, and the movable frame 2 and the fixed groove 3 are installed on the upper end of the telescopic rod 7. Therefore, the height of the movable frame 2 and the fixed groove 3 can be adjusted by adjusting the length of the telescopic rod 7 extending in the fixed rod 6. In addition, the periphery of the telescopic rod 7 is provided with scales, so that the extended length of the telescopic rod 7 can be read through the scales after the telescopic rod 7 is extended, so as to facilitate the evaluation of the height of the laser rangefinder from the ground.

[0021] like Figure 2 As shown, a fixing plate 8 is also provided on the outer periphery of the fixing rod 6, and the fixing plate 8 is fixed to the upper end of the fixing rod 6 by welding. Three hinge supports are fixed on the fixing plate 8, and the hinge supports on the fixing plate 8 are hinged to the upper end of the leg 5. In addition, a sliding sleeve 9 is also embedded on the outer periphery of the fixing rod 6, and the sliding sleeve 9 can slide up and down relative to the fixing rod 6. A hinge support is provided on the outer periphery of the sliding sleeve 9, and correspondingly, a hinge support is also provided on the leg 5, and the hinge support on the sliding sleeve 9 is connected to the hinge support on the leg 5 through a connecting rod 10. Therefore, when the sliding sleeve 9 slides downward relative to the fixing rod 6, the leg 5 can be opened, and when the sliding sleeve 9 slides upward relative to the fixing rod 6, the leg 5 can be closed.

[0022] In addition, the axial direction of the fixing rod 6 is perpendicular to the upper surface of the fixing plate 8, and a level 11 is also installed on the fixing plate 8, so that the level 11 can be used to determine whether the fixing rod 6 is in a vertical position. Correspondingly, the leg 5 includes a sleeve 12 and a leg 13 that can be extended and retracted relative to the sleeve 12. Specifically, the two ends of the sleeve 12 are respectively hinged to the hinge support and the connecting rod 10 on the fixing plate 8. Therefore, by adjusting the length of the leg 13, the length of the leg 5 can be adjusted, thereby adjusting the angle of the central axis 4, so that the central axis 4 remains in a vertical position.

[0023] On the other hand, the bottom of the movable frame 2 is rotatably mounted on the upper end of the central axis 4 of the tripod 1. Figure 3As shown, the movable frame 2 includes two vertical frames, and the tops of the two vertical frames are provided with threaded holes, and the threaded holes on the two vertical frames have coaxial centers, thereby the installation of the fixing groove 3 can be achieved through the two threaded holes on the vertical frames. The fixing groove 3 includes a U-shaped base, and studs A14 and studs B15 are fixed on both sides of the U-shaped base, respectively. The rotation directions of the studs A14 and B15 are the same and are on the same horizontal axis, and the studs A14 and B15 are respectively installed in the two threaded holes of the vertical frames, thereby the flipping of the fixing groove 3 in the movable frame 2 can be achieved. More specifically, the stud A14 passes through the threaded hole at the top of the movable frame 2 and is tightened by the adjusting nut A16, and the stud B15 passes through the threaded hole at the top of the movable frame 2 and is tightened by the adjusting nut B17. Therefore, after tightening the adjusting nuts A16 and B17, the fixing groove 3 can be locked in the movable frame 2. It should be understood that in actual operation, when the fixing slot 3 is flipped relative to the movable frame 2, the fixing slot will have a horizontal displacement relative to the movable frame 2. Since the size of the horizontal displacement is not greater than the pitch of the stud A14 or the stud B15, it can be ignored.

[0024] The fixing groove 3 also includes two clamping plates 18, and the two clamping plates 18 are located inside the U-shaped bottom bracket. The laser rangefinder can be clamped by the two clamping plates 18 in the U-shaped bottom bracket, so that the laser rangefinder is relatively fixed to the fixing groove 3. Specifically, the clamping plates 18 are connected to the two inner walls of the U-shaped bottom bracket through springs. In addition, a slide rail is also provided at the bottom of the U-shaped bottom bracket, and a slide groove matching the slide rail is provided at the bottom of the two clamping plates 18. Therefore, when the laser rangefinder is installed, the clamping plates 18 can be prevented from shaking through the cooperation of the slide rail and the slide groove, which is conducive to maintaining the stability of the laser rangefinder.

[0025] Combination Figure 2 , Figure 3 As shown, a stud C19 is vertically fixed to the bottom of the movable frame 2. Correspondingly, a threaded hole is provided at the upper end of the tripod, i.e., the upper end of the central axis 4. The stud C19 can be installed in the threaded hole at the upper end of the central axis 4. Thus, the movable frame 2 can rotate relative to the tripod 1, thereby realizing the angle adjustment of the laser rangefinder in the horizontal direction. In addition, the outer periphery of the stud C19 is also equipped with an adjusting nut C20. When the adjusting nut C20 is tightened, it can press the upper end of the central axis 4, thereby preventing the movable frame 2 from continuing to rotate. It should be understood that in actual operation, when the movable frame 2 rotates relative to the tripod 1, the movable frame 2 will change in height relative to the tripod 1 in the vertical direction. Since the size of the height change is not greater than the pitch of the stud C19, it can be ignored.

[0026] When the present invention is used for distance measurement, its working principle is as follows: The laser rangefinder is installed in the fixing slot 3. When the angle of the laser rangefinder needs to be adjusted horizontally, first loosen the adjusting nut C20, rotate the movable frame 2 horizontally to the desired angle, and then tighten the nut C. When the angle of the laser rangefinder needs to be adjusted vertically, first loosen the adjusting nut A16 or the adjusting nut B17, flip the fixing slot 3 to the desired angle, and then tighten the nut A and nut B.
