Description

Technical Field

[0001] The utility model relates to the technical field of engineering cost, in particular to a fixing device for an engineering cost laser rangefinder. Background Art

[0002] A laser rangefinder is an instrument that uses a certain parameter of a modulated laser to accurately measure the distance to a target. A pulsed laser rangefinder emits one or a series of short pulsed laser beams toward a target. The photoelectric element receives the laser beam reflected by the target. The timer measures the time from emission to reception of the laser beam and calculates the distance from the rangefinder to the target. When the power of the emitted laser beam is sufficient, the range of the rangefinder can reach about 40 kilometers or even farther. The laser rangefinder can operate day and night, so it is widely used in engineering cost.

[0003] However, in the prior art, in order to improve the accuracy of laser rangefinder measurement during distance measurement, it is generally necessary to place the laser rangefinder on a fixed bracket for measurement to prevent it from shaking and affecting data errors. Since the existing laser rangefinder fixed bracket lacks a corresponding fixing device, it is easy to collide with the laser rangefinder due to external factors such as human factors, resulting in inaccurate measurement data, and even causing the laser rangefinder to fall and break. Secondly, the fixed bracket is integrated, and when the measurement angle needs to be changed, it can only be changed by moving the entire device, which is very time-consuming and labor-intensive, and has low flexibility. Utility Model Content

[0004] The purpose of the utility model is to solve the problems existing in the prior art.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it includes: a fixed bracket, a plurality of supporting legs are hinged on the outer wall surface of the fixed bracket, a handle is fixedly installed on the outer wall surface of the fixed bracket, a base is fixedly installed on the top surface of the fixed bracket, a turntable is rotatably connected to the top surface of the base, a limiting assembly is provided on the annular side wall of the turntable, a clamping assembly is provided on the top surface of the turntable, and the clamping assembly includes four support brackets, each two of the four support brackets are symmetrically and evenly fixed on the top surface of the turntable in a group, a long plate is fixedly installed on the surface of each two of the support brackets, a threaded rod is connected between the two long plates through a bearing, a knob is fixedly installed on the surface of the threaded rod, and the threads on the surface of the threaded rod are reverse threads with the knob as the center.

[0006] As a preferred embodiment, a long rod is fixedly installed between the two long plates, and two support plates are threadedly connected to the surface of the threaded rod, and the two support plates slide with the help of the threaded rod and the long rod.

[0007] As a preferred embodiment, a clamping plate is fixedly installed on the top surface of the two support plates, an anti-slip strip is fixedly installed on one side surface of the two clamping plates, and a laser rangefinder body is movably installed between the two clamping plates.

[0008] As a preferred embodiment, the limiting assembly includes an extension block, which is fixedly mounted on the annular side wall of the turntable, a push handle is fixedly mounted on one side surface of the extension block, connecting rods are fixedly mounted between the annular side wall of the turntable and the two side surfaces of the extension block, discs are fixedly mounted on the surfaces of two connecting rods, rings are slidably connected to the surfaces of the two connecting rods, and springs are fixedly mounted between the two rings and the two discs.

[0009] As a preferred embodiment, two U-shaped rods are fixedly installed on the annular side wall of the turntable, and the surfaces of the two U-shaped rods are slidably connected with sliding plates. Both side surfaces of the sliding plates are hinged with hinged plates, and the ends of the two hinged plates away from the sliding plates are hinged to two circular rings.

[0010] As a preferred embodiment, a limiting plate is fixedly mounted on the bottom surface of the sliding plate, a plurality of limiting grooves are evenly formed on the top surface of the base, and one end of the limiting plate away from the sliding plate is located inside the limiting groove.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] 1. The utility model provides a clamping assembly. When the laser rangefinder needs to be fixed, the knob is first rotated, and the rotation of the knob drives the threaded rod to rotate. Since the threads on the surface of the threaded rod are mutually reverse threads with the knob as the center, when the knob drives the threaded rod to rotate, the two support plates connected by the threads on its surface will move in the direction away from each other on the surface of the long rod. The two support plates move in the direction away from each other on the surface of the long rod, driving the two clamping plates to move in the direction away from each other. When the distance between the two clamping plates can place the laser rangefinder body, the knob is rotated in the opposite direction, so that the two support plates move in the direction close to each other on the surface of the long rod. The two support plates move toward each other on the surface of the long rod, driving the two clamping plates to move toward each other. The two clamping plates move toward each other, so that the laser rangefinder body is firmly clamped and limited between the two clamping plates. When the laser rangefinder body is firmly clamped and limited, just stop rotating the knob. Through the cooperation of the above structure, the device can firmly clamp the laser rangefinder body on the surface of the fixed bracket to avoid shaking during distance measurement, thereby affecting the measurement error, improving the stable connection between the laser rangefinder and the fixed bracket, and at the same time improving the convenience and stability of use.

[0013] 2. The utility model provides a limit assembly. When only the distance measuring direction of the rangefinder needs to be changed, the sliding plate is first pushed. The sliding plate moves to slide on the surface of the U-shaped rod. The sliding of the sliding plate on the surface of the U-shaped rod drives the two hinged plates to move. The movement of the two hinged plates drives the two rings to move on the surfaces of the two connecting rods. The movement of the two rings on the surfaces of the connecting rods squeezes the two springs, causing the two springs to be compressed. At the same time, the sliding of the sliding plate on the surface of the U-shaped rod also drives the limit plate to move. The limit plate moves to move itself out of the inside of the limit groove. The limit plate moves out of the inside of the limit groove, causing The turntable loses its limit position on the surface of the base, and the push handle is pushed at this time. The movement of the push handle drives the extension block to move, and the movement of the extension block drives the disc to rotate on the top surface of the base. When the laser rangefinder body reaches a suitable position, the push handle is stopped and the sliding plate is released. The spring rebound force is used to reinsert the limit plate into the corresponding limit groove, thereby re-limiting the turntable on the surface of the base, that is, completing the change of the ranging direction of the rangefinder. Through the cooperation of the above structure, when the ranging direction needs to be changed, it can be completed conveniently and quickly, avoiding moving the entire device, thereby improving the practicality of the device.

[0026] In one embodiment, a clamping plate 607 is fixedly mounted on the top surface of the two support plates 606 , an anti-slip strip 608 is fixedly mounted on one side surface of the two clamping plates 607 , and a laser rangefinder body 609 is movably mounted between the two clamping plates 607 .

[0027] Specifically, the two clamping plates 607 are provided to clamp the limit-position laser rangefinder body 609 .

[0028] In one embodiment, the limiting assembly 7 includes an extension block 701, which is fixedly mounted on the annular side wall of the turntable 5, a push handle 702 is fixedly mounted on one side surface of the extension block 701, connecting rods 703 are fixedly mounted between the annular side wall of the turntable 5 and the two side surfaces of the extension block 701, discs 704 are fixedly mounted on the surfaces of the two connecting rods 703, rings 705 are slidably connected to the surfaces of the two connecting rods 703, and springs 706 are fixedly mounted between the two rings 705 and the two discs 704.

[0029] Specifically, the setting of the push handle 702 has the effect of driving the rotating disk 5 to rotate, and the setting of the spring 706 has the effect of limiting the position of the ring 705 on the surface of the connecting rod 703.

[0031] Specifically, the setting of the hinge plate 709 has the effect of driving the ring 705 to slide on the surface of the connecting rod 703 .

[0033] Specifically, the setting of the limiting plate 710 and the limiting groove 711 has the effect of limiting the rotation of the disc 704 .

[0034] Working principle: When the laser rangefinder needs to be fixed, first turn the knob 604. The rotation of the knob 604 drives the threaded rod 603 to rotate. Since the threads on the surface of the threaded rod 603 are reverse threads with the knob 604 as the center, when the knob 604 drives the threaded rod 603 to rotate, the two support plates 606 threadedly connected on the surface will move away from each other on the surface of the long rod 605. The two support plates 606 move away from each other on the surface of the long rod 605, driving the two clamping plates 607 to move away from each other. When the distance between the two clamping plates 607 is enough to place the laser rangefinder body 609, the knob 604 is rotated in the opposite direction, so that the two support plates 606 are on the long rod 605. The surfaces of the two support plates 606 move in a direction approaching each other on the surface of the long rod 605, driving the two clamping plates 607 to move in a direction approaching each other. The two clamping plates 607 move in a direction approaching each other, so that the laser rangefinder body 609 is firmly clamped and limited between the two clamping plates 607. When the laser rangefinder body 609 is firmly clamped and limited, it is sufficient to stop rotating the knob 604. Through the cooperation of the above structure, the device can firmly clamp the laser rangefinder body 609 on the surface of the fixed bracket 1 to avoid shaking during distance measurement, thereby affecting the measurement error, improving the stable connection between the laser rangefinder and the fixed bracket 1, and improving the convenience of use. Advantages and stability; when only the direction of distance measurement of the rangefinder needs to be changed, the sliding plate 708 is pushed first, and the sliding plate 708 moves to slide on the surface of the U-shaped rod 707. The sliding of the sliding plate 708 on the surface of the U-shaped rod 707 drives the two hinged plates 709 to move. The movement of the two hinged plates 709 drives the two rings 705 to move on the surfaces of the two connecting rods 703. The movement of the two rings 705 on the surfaces of the connecting rods 703 will squeeze the two springs 706, so that the two springs 706 are compressed. At the same time, the sliding of the sliding plate 708 on the surface of the U-shaped rod 707 also drives the limit plate 710 to move. The limit plate 710 moves to move itself out of the inside of the limit groove 711, and the limit plate 710 moves out from the inside of the limit groove 711. The rotating disk 5 loses its limit position on the surface of the base 4. At this time, the push handle 702 is pushed, and the push handle 702 moves to drive the extension block 701 to move, and the extension block 701 moves to drive the disc 704 to rotate on the top surface of the base 4. When the laser rangefinder body 609 reaches a suitable position, the push handle 702 is stopped and the sliding plate 708 is released. The rebound force of the spring 706 is used to reinsert the limit plate 710 into the corresponding limit groove 711, so that the rotating disk 5 is limited to the surface of the base 4 again, that is, the distance measuring direction of the rangefinder is changed. Through the cooperation of the above structure, when the distance measuring direction needs to be changed, it can be completed conveniently and quickly, avoiding moving the entire device, thereby improving the practicality of the device.
