Description

Technical Field

[0001] The utility model relates to the technical field of instrument inspection, in particular to a verticality inspection tool for a laser rangefinder. Background Art

[0002] A laser rangefinder is an instrument that uses laser technology to measure distance. It uses a laser to generate a laser beam to measure the distance of a target. Its working principle is to emit a laser beam, receive the laser reflected by the target, and finally calculate the distance between the target and the laser rangefinder based on the time between the laser emission and the laser reflection. To ensure the accuracy of the distance measurement of the laser rangefinder, the verticality of the laser emission of the laser rangefinder needs to be tested before the laser rangefinder leaves the factory. If the laser emitted by the laser rangefinder cannot be emitted vertically to the target, the time between the laser emission and the laser reflection will be longer, and the calculated distance between the target and the laser rangefinder will be too large. Therefore, in order to ensure that the measurement result of the laser rangefinder is within the allowable error range, it is necessary to ensure that the error of the verticality of the laser emitted by the laser rangefinder is within a certain range.

[0003] The existing solution for testing the verticality of laser rangefinder laser emission is to let the laser rangefinder emit laser vertically to the target object, test the landing point of the reflected laser, and judge the verticality of the laser emission of the laser rangefinder. The ranging ranges of laser rangefinders on the market are inconsistent. For laser rangefinders with a larger ranging range, the laser rangefinder is far away from the target object. When testing the verticality of the laser emission of the laser rangefinder, it occupies a large space. It is difficult for the staff to determine whether the laser rangefinder and the target object are in a mutually perpendicular state, which affects the judgment of the test result of the verticality of the laser emitted by the laser rangefinder.

[0004] Therefore, there is an urgent need for a laser rangefinder verticality inspection tool to solve the above technical problems. Utility Model Content

[0034] like Figure 1 and Figure 2As shown in , this embodiment provides a laser rangefinder verticality inspection tool for calibrating the verticality of the laser emission of the laser rangefinder 100 to ensure the accuracy of the laser rangefinder 100. The laser rangefinder verticality inspection tool comprises a first mounting member 1, a second mounting member 2 and an inspection member 3, wherein a laser rangefinder 100 is mounted on the first mounting member 1, the second mounting member 2 is arranged opposite to and parallel to the first mounting member 1, and a target object 200 irradiated by the laser rangefinder 100 is mounted on the second mounting member 2. When performing the verticality inspection, the laser emitted by the laser rangefinder 100 is irradiated toward the target object 200, and the surface of the target object 200 that receives the laser is a flat mirror surface. According to the principle of mirror reflection, for the flat mirror surface, its imaging feature is that the two sides are equal and are divided equally by the center. At this time, the actual distance between the laser rangefinder 100 and the target object 200 is half of the required test distance to meet the test requirements of the laser rangefinder 100. For the verticality inspection of the long-distance laser rangefinder 100, the occupied space of the laser rangefinder 100 and the target object 200 can be reduced, which makes it more convenient for the staff to adjust the distance between the two, and simplifies the staff's verification work.

[0035] The inspection piece 3 is used to detect the verticality of the reflected laser, wherein the inspection piece 3 is placed in front of the laser emission port of the laser rangefinder 100. A center hole is provided on the inspection piece 3. During the calibration work, it is necessary to adjust the placement position of the inspection piece 3 so that the laser emitted by the laser rangefinder 100 and irradiated onto the target object 200 passes through the center hole. The size of the inspection piece 3 is designed according to the verticality error range of the laser emission of the laser rangefinder 100. If the verticality of the emitted laser of the laser rangefinder 100 is within the error range, the reflected light spot will irradiate the area of ​​the inspection piece 3 where no center hole is provided, so as to assist the staff in determining whether the verticality of the laser emission of the laser rangefinder 100 meets the use requirements.

[0036] Preferably, the areas other than the center hole on the inspection piece 3 are white. Compared with other colors, white can make the light spots reflected back to the inspection piece 3 more obvious, which is convenient for staff to observe and speeds up the inspection speed of the verticality of the laser emitted by the laser rangefinder 100.

[0037] In this embodiment, the laser rangefinder verticality inspection tool also includes a base plate 4 and a track 5. The track 5 is laid on the base plate 4 and is provided with a scale. One of the first mounting member 1 and the second mounting member 2 is fixed to the base plate 4, and the other is slidably provided on the track 5. This makes it convenient for the staff to adjust the position of the laser rangefinder 100 or the target object 200 and ensure the accuracy of the parking position. Alternatively, the first mounting member 1 and the second mounting member 2 can be slidably provided on the track 5 to enable the staff to adjust the distance between the two. Regarding the assembly method of the first mounting member 1 and the second mounting member 2, the staff can formulate it according to their own needs, and there is no specific restriction.

[0039] Specifically, when the first mounting member 1 slides on the track 5, the first base 11 includes a first bottom plate 111 and a first slider 112, the first slider 112 is located below the first bottom plate 111, the first slider 112 is assembled on the track 5, and a first slide groove is provided on the first slider 112, so that the first base 11 moves along the track 5, and then the first mounting member 1 can move along the track 5 to adjust the position of the laser rangefinder 100. Specifically, during assembly, the first mounting plate 12 is arranged perpendicular to the first bottom plate 111. Preferably, the first mounting member 1 also includes a handle 113, which is mounted on the first bottom plate 111. The arrangement of the handle 113 facilitates the staff to adjust the upper position of the first mounting member 1 on the track 5 with more effort. On the other hand, when the first mounting member 1 is fixedly arranged on the bottom plate 4, the first mounting member 1 includes a first base 11 and a first mounting plate 12, wherein the first base 11 is fixedly connected to the bottom plate 4, and the first mounting plate 12 is arranged perpendicular to the first base 11.

[0040] Preferably, the first mounting member 1 further includes two side panels 13, which are located on the first base 11, wherein the side panels 13 are provided with fixing grooves along their height direction, and during assembly, the fixing grooves of the two side panels 13 are arranged opposite to each other, and the first mounting plate 12 is placed between the two side panels 13, and its side is placed in the fixing grooves. The provision of the side panels 13 can strengthen the stability of the placement of the first mounting member 1, ensure the stable placement of the laser rangefinder 100, and improve the accuracy of the verticality test result of the laser emission of the laser rangefinder 100.

[0041] Exemplarily, when the second mounting member 2 is fixedly connected to the bottom plate 4, the second mounting member 2 includes a second base 21 and a second mounting plate 22, wherein the second base 21 is fixedly connected to the bottom plate 4, the second mounting plate 22 is arranged perpendicular to the second base 21, and the second base 21 faces the second mounting plate 22, and the target 200 is placed on the second mounting plate 22, so that the laser rangefinder 100 and the target 200 are perpendicular to each other and arranged relative to each other, thereby improving the accuracy of the verticality of the laser emission of the laser rangefinder 100. On the other hand, when the second mounting member 2 is slidably arranged on the track 5, the second mounting member 2 includes a second base 21 and a second mounting plate 22, wherein the second base 21 includes a second bottom plate 4 and a second slider, wherein a guide groove is arranged on the second slider, and the guide groove can slide along the track 5, so that the second slider moves along the track 5, so that the second mounting member 2 slides on the track 5, wherein the second mounting plate 22 is perpendicular to the second base 21, and the target 200 is placed on the second mounting plate 22 and faces the laser rangefinder 100.

[0042] Preferably, the track 5 is composed of two parallel slide rails, so that the first mounting member 1 and / or the second mounting member 2 can run more stably on the track 5, further improving the stability of the laser rangefinder verticality inspection tooling structure. Preferably, the bottom plate 4 is a hollow structure to reduce the overall weight of the laser rangefinder verticality inspection tooling and facilitate its transportation. At the same time, it is preferred to set a plurality of legs 6 at intervals on the bottom surface of the bottom plate 4 to ensure that the laser rangefinder verticality inspection tooling can be stably placed.

[0043] The present embodiment provides a method for using a tool for inspecting the verticality of an optical rangefinder. The first mounting member 1 is slid to fit the first mounting member 1 and the second mounting member 2. A plug gauge is then used to check the flatness of the fit between the two to ensure that the first mounting member 1 and the second mounting member 2 are opposite and parallel. A laser rangefinder 100 is mounted on the first mounting member 1, and a target object 200 is mounted on the second mounting member 2. An inspection member 3 is mounted at the front end of a laser emission port in the laser rangefinder 100 so that the laser emitted by the laser rangefinder 100 passes through a central hole of the inspection member 3 and irradiates the target object 200. The distance between the first mounting member 1 and the second mounting member 2 is adjusted according to a required test distance to adjust the distance between the laser rangefinder 100 and the target object 200. Then, whether there is a light spot on the inspection member 3 is observed to determine the verticality of the laser emitted by the laser rangefinder 100.
