[0002] Laser distance measuring device is a device that uses laser technology to measure distance. It calculates the distance between the target object and the rangefinder by emitting a laser beam and measuring the propagation time of the beam or the reflection of the beam. It is widely used in the fields of construction, surveying, engineering, geological exploration, industrial manufacturing, etc. It can accurately measure the distance of the target object and provide high-precision measurement results.

[0003] In the prior art, when a laser distance measurement test device is placed, it is difficult to place the laser distance measurement test device horizontally due to the unevenness of the ground during measurement, which causes the position to be easily offset. If the device is tilted or non-horizontal, the measurement path of the laser beam is misunderstood as the oblique distance or hypotenuse distance, resulting in deviation in the distance measurement result, thereby reducing the accuracy of the measurement and ultimately affecting the measurement result. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a laser distance measurement test device, which solves the problem that the laser distance measurement test device is difficult to be placed horizontally, resulting in easy position deviation and reduced measurement accuracy.

[0006] Preferably, a tripod is fixedly mounted on the bottom end of the fixing frame, and a plurality of holes are provided on the tripod, and the length can be adjusted through the holes.

[0007] Preferably, a connecting plate is provided in the middle of the mounting frame, and a plurality of grooves which are adapted to the laser rangefinder are formed on the connecting plate.

[0008] Preferably, one end of the conduit away from the corresponding liquid storage ball is inclined toward the arc frame.

[0009] Preferably, a guide frame is provided between every two adjacent support rods, a support frame is fixedly connected between the guide frame and the inner bottom wall of the fixed frame, the conduit passes through the middle of the guide frame, and the conduit is made of hard material.

[0010] Preferably, the hard material is made of PVC.

[0011] Preferably, limit plates are provided on both sides of the guide frame, and the limit plates and the conduit are in close contact with each other.

[0012] Preferably, a rubber tube is provided at one end of the conduit away from the corresponding liquid storage ball, and two adjacent conduits are fixed to each other via the rubber tube, and the rubber tube is made of elastic material.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

DETAILED DESCRIPTION

[0024] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-Figure 5 As shown, a laser distance measurement test device includes a fixing frame 2, a tripod 1 is fixedly installed at the bottom end of the fixing frame 2, the tripod 1 is used to contact the ground and support the fixing frame 2, and a plurality of holes are provided on the tripod 1 to facilitate adjustment of the extension length of the tripod 1, the fixing frame 2 is U-shaped, a mounting frame 4 is rotatably connected between the two ends of the fixing frame 2, a laser distance meter 3 is fixedly installed in the middle of the mounting frame 4, a connecting plate 14 is provided in the middle of the mounting frame 4, and a plurality of grooves that are mutually adapted to the laser distance meter 3 are provided on the connecting plate 14, so as to increase the stability of the installation between the laser distance meter 3 and the mounting frame 4, and the installation An arc frame 10 is fixedly connected to the bottom end of the frame 4, and a plurality of support rods 9 are fixedly connected to one end of the arc frame 10 away from the mounting frame 4. The support rods 9 and the arc frame 10 are symmetrically arranged about the central axis of the mounting frame 4. The interiors of the support rods 9 and the arc frame 10 are hollow. A liquid storage ball 11 is arranged at one end of the support rod 9 away from the arc frame 10. The liquid storage ball 11 is connected to the corresponding support rod 9. Both sides of the liquid storage ball 11 are fixedly connected with a conduit 12. The ends of two adjacent conduits 12 are fixed to each other and are connected internally. The end of the conduit 12 away from the corresponding liquid storage ball 11 is inclined toward the arc frame 10 to increase the liquid storage amount near the lowest end liquid storage ball 11.

[0026] When the fixing frame 2 is offset due to the placement of the tripod 1, the position of the laser rangefinder 3 deviates from the horizontal direction. After the deviation, since the multiple liquid storage balls 11 are interconnected through the conduit 12, the liquid in the liquid storage ball 11 moves toward the lowest liquid storage ball 11 due to gravity. At this time, the weight of the entire device is concentrated on the lowest liquid storage ball 11, and the conduits 12 on both sides of the liquid storage ball 11 evenly divide the inflowing liquid to improve the uniformity of weight. As the amount of liquid in the liquid storage ball 11 at the lowest end increases, the liquid in the liquid storage ball 11 drives the corresponding support rod 9 to be in a vertical state through its own gravity. The whole process ensures that the entire counterweight of the laser rangefinder 3 is always located at the lowest end in the vertical direction, improving the adjustment ability of the weight of the liquid storage ball 11, and the support rod 9 is perpendicular to the laser rangefinder 3, thereby ensuring that the laser rangefinder 3 is always in a horizontal state, which is convenient for the laser rangefinder 3 to measure the distance of the object, thereby improving the accuracy of the measurement.

[0027] As an implementation method in this embodiment, Figure 1 , Figure 2 and Figure 5 As shown, a guide frame 5 is arranged between every two adjacent support rods 9, and a conduit 12 runs through the middle of the guide frame 5. The conduit 12 is made of a hard material, such as PVC. A support frame 6 is fixedly connected between the guide frame 5 and the inner bottom wall of the fixed frame 2. Limiting plates 7 are arranged on both sides of the guide frame 5. The limiting plates 7 and the conduit 12 are in close contact with each other. The guide frame 5 and the limiting plates 7 are used to guide the conduit 12, increase the stability of the liquid storage ball 11 and the conduit 12 rotating back and forth, and a rubber tube 13 is arranged at one end of the conduit 12 away from the corresponding liquid storage ball 11. The two adjacent conduits 12 are fixed to each other through the rubber tube 13, and the rubber tube 13 is made of elastic material. The guide frame 5 is made of a rubber material, such as a corrugated bar 8, and the corrugated bar 8 and the rubber tube 13 are adapted to each other. When the liquid storage ball 11 rotates due to the liquid inside it, the rubber tube 13 and the corrugated bar 8 contact each other. The rubber tube 13 is elastically deformed by the contact of the corrugated bar 8, which promotes the liquid in the rubber tube 13 to flow toward the liquid storage ball 11 at the bottom, reduces the accumulation of liquid in the rubber tube 13, and helps the laser rangefinder 3 to be horizontally adjusted. The guide frame 5 prevents the entire mounting frame 4 from automatically adjusting the angle excessively, ensures that the entire laser rangefinder 3 is located in the fixing frame 2, and prevents the laser rangefinder 3 from colliding with the ground when the entire equipment collapses.

[0028] The working principle of the utility model is as follows: when in use, the staff spreads the tripod 1 and adjusts the length to contact the ground. When the tripod 1 is spread, the fixing frame 2 is tilted. When the fixing frame 2 is tilted, the liquid storage balls 11 are connected to each other through the conduit 12. The liquid in the liquid storage balls 11 moves toward the liquid storage ball 11 at the lowest end due to gravity. At this time, the weight of the entire device is concentrated on the liquid storage ball 11 at the lowest end. Due to the increase of liquid in the liquid storage ball 11 at the lowest end, the liquid in the liquid storage ball 11 drives the corresponding support rod 9 to be in a vertical state through its own gravity. The entire process The process ensures that the entire counterweight of the laser rangefinder 3 is always located at the lowest end in the vertical direction, thereby improving the adjustment ability of the weight of the liquid storage ball 11. At the same time, the rubber tube 13 is elastically deformed by the contact of the wave bar 8, which promotes the liquid in the rubber tube 13 to flow toward the liquid storage ball 11 at the bottom, reducing the accumulation of liquid at the rubber tube 13. The liquid storage ball 11 at the lowest end drives the entire mounting frame 4 to deflect. Since the liquid in the liquid storage ball 11 is always at the lowest end, and the support rod 9 and the laser rangefinder 3 are perpendicular to each other, it is ensured that the laser rangefinder 3 is always in a horizontal state, thereby improving the accuracy of measurement.

[0029] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
