[0001] The utility model relates to the technical field of rangefinders, in particular to a rangefinder for civil engineering. Background Technique
[0002] In civil engineering, a rangefinder is a commonly used measuring tool for measuring parameters such as distance, height, and angle. When using a rangefinder, it is usually necessary to install it on a bracket to ensure the accuracy and stability of the measurement.
[0003] However, when the existing rangefinders for civil engineering are installed, most of them fix the rangefinder and the bracket through bolts. During the installation process, it is necessary for personnel to always hold the bracket or the rangefinder to align the installation holes between the two before bolt fixation. Since it is necessary for personnel to always hold the bracket or the rangefinder to align the installation holes between the two before bolt fixation, the installation efficiency is low, and a large amount of time and manpower are required. During the installation process, since it is necessary for personnel to always hold the bracket or the rangefinder, accidental touch is likely to occur, resulting in the offset of the rangefinder, which in turn affects the installation efficiency and requires personnel to constantly adjust, wasting time.

A clamping groove 41 is opened on the inner wall of the stable groove 40. The connection component 4 further includes a cavity 42. A fixed cylinder 43 is fixed on the inner wall of the cavity 42. A connection groove 403 is opened at the bottom of the fixed cylinder 43. A semi-gear 45 is rotatably connected to the inner wall of the cavity 42. The teeth of the semi-gear 45 penetrate through the connection groove 403. A fixed column 47 is fixed on the inner wall of the cavity 42. A cylinder 48 is fixed on the top of the semi-gear 45. Through holes 46 are opened on the surfaces of both the semi-gear 45 and the cylinder 48. The fixed column 47 penetrates through the through holes 46. A resisting groove 49 is opened on the surface of the cylinder 48. A round rod 400 abuts against the inner wall of the resisting groove 49. A clamping plate 401 is fixed on the surface of the round rod 400. A first spring 402 is fixed on the surface of the clamping plate 401. One end of the first spring 402 away from the clamping plate 401 is fixed on the surface of the fixed column 47. One side of the clamping plate 401 away from the fixed column 47 penetrates through the fixed cylinder 43, and the clamping plate 401 is slidably connected with the fixed cylinder 43. A long rod 404 is arranged inside the cavity 42. The long rod 404 penetrates through the cavity 42 and is slidably connected with the support 3. A clamping tooth 405 is fixed on the surface of the long rod 404. The clamping tooth 405 meshes with the semi-gear 45. A pulling plate 406 is fixed on the surface of the long rod 404. Both the stable groove 40 and the fixed cylinder 43 are provided in two groups, and the two groups of stable grooves 40 and fixed cylinders 43 are symmetrically arranged with the center lines of the distance measuring instrument body 1 and the support 3 as the symmetry axes. One of the two groups of stable grooves 40 and fixed cylinders 43 is square, and the other group is cylindrical. One end surface of the clamping plate 401 away from the first spring 402 is provided with an inclined surface, and the resisting groove 49 is provided in an arc shape. When the fixed cylinder 43 is installed into the stable groove 40, through the square and cylindrical shapes provided, it is convenient for personnel to position and can be quickly installed. Through the first spring 402, the fixed column 47, the resisting groove 49, and the round rod 400, each clamping plate 401 can enter the clamping groove 41, so that the distance measuring instrument body 1 and the support 3 can be stably limited. At this time, personnel can use bolts to fix the installation frame 2 and the support 3, without the need for personnel to always hold the two, and there will be no accidental touch, resulting in the deviation of the distance measuring instrument body 1, improving the installation efficiency.
[0025] The limit assembly 5 includes a connecting hole 50, which is provided on the surface of the pull plate 406. A ring 51 is rotatably connected to the surface of the bracket 3. A rotating rod 52 is rotatably connected to the surface of the bracket 3. The rotating rod 52 passes through the ring 51 and is rotatably connected to the ring 51. A stopper 53 is fixed to the end of the rotating rod 52 away from the bracket 3. A sliding groove 54 is provided on the inner side of the ring 51. A stabilizing plate 55 is slidably connected to the inner wall of the sliding groove 54. A spring 2 is fixed to the surface of the stabilizing plate 55. 56, one end of the spring 2 56 away from the stabilizing plate 55 is fixed on the inner wall of the slide groove 54, a groove 57 is provided on the surface of the rotating rod 52, and one end of the stabilizing plate 55 away from the spring 2 56 is set in an arc shape, and the stopper 53 is rotated. The stopper 53 and the connecting hole 50 are staggered, and the surface of the stopper 53 contacts the surface of the pull plate 406, limiting the pull plate 406 to prevent the pull plate 406 from being pulled accidentally, causing the card plate 401 to be separated from the card slot 41, affecting the stability of the rangefinder body 1 and the bracket 3.
[0026] When the rangefinder body 1 needs to be used, rotate the block 53 so that the block 53 is parallel to the connection hole 50. At the same time, when the block 53 rotates, it drives the rotating rod 52 to rotate synchronously. At this time, the inner wall of the groove 57 abuts against the arc surface of the surface of the stabilizing plate 55. At this time, the stabilizing plate 55 enters the sliding groove 54, and at the same time, the second spring 56 is compressed. When the block 53 is parallel to the connection hole 50, the stabilizing plate 55 is parallel to another groove 57, and the second spring 56 is released. The stabilizing plate 55 enters the groove 57 to stabilize the rotating rod 52 and the block 53. At this time, install the fixed cylinder 43 into the stabilizing groove 40. Through the set square and cylindrical shape, it is convenient for personnel to position and can be quickly installed. The inner wall of the stabilizing groove 40 abuts against the inclined surface of the clamping plate 401. At this time, the clamping plate 401 enters the fixed cylinder 43 and drives the round rod 400 to move synchronously. The surface of the round rod 400 abuts against the abutting groove 49 to drive the cylinder 48 to rotate forward. At the same time, when the clamping plate 401 moves, the first spring 402 is compressed. When the position of the clamping plate 401 is parallel to the position of the clamping groove 41, at this time, the first spring 402 is released, and the clamping plate 401 enters the clamping groove 41. Through the round rod 400 and the abutting groove 49, the cylinder 48 rotates in reverse, so that each clamping plate 401 enters the clamping groove 41, and the rangefinder body 1 and the bracket 3 can be stably limited. At the same time, when the cylinder 48 rotates, it drives the half gear 45 to rotate, and then drives the clamping teeth 405, the long rod 404, and the pull plate 406 to move synchronously. The block 53 passes through the connection hole 50 and does not affect the normal movement of the pull plate 406 and the long rod 404. When the rangefinder body 1 and the bracket 3 are limited, continue to rotate the block 53 so that the block 53 intersects with the connection hole 50. The surface of the block 53 abuts against the surface of the pull plate 406, which can limit the pull plate 406 to prevent accidental pulling of the pull plate 406, resulting in the clamping plate 401 being disengaged from the clamping groove 41 and affecting the stability of the rangefinder body 1 and the bracket 3. At this time, the personnel can bolt-fix the mounting frame 2 and the bracket 3 through bolts, without the need for personnel to always hold the two, and there will be no accidental touch, resulting in the offset of the rangefinder body 1, improving the installation efficiency. When the rangefinder body 1 and the bracket 3 need to be removed, remove the bolts and rotate the block 53 so that the block 53 is parallel to the connection hole 50. At this time, pull the pull plate 406 outwards, and the long rod 404 and the clamping teeth 405 move, driving the half gear 45 to rotate forward, so that the cylinder 48 and the abutting groove 49 rotate synchronously. The inner wall of the abutting groove 49 abuts against the round rod 400, driving the clamping plate 401 to disengage from the clamping groove 41. At this time, the rangefinder body 1 and the bracket 3 can be normally separated.
[0027] The above generally describes the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
