Description

Technical Field

[0001] The utility model relates to the technical field of laser rangefinders, in particular to a laser rangefinder positioning device. Background Art

[0002] When working, the laser rangefinder emits a very thin laser beam to the object to be measured. The laser beam reflected by the object to be measured is received by the photoelectric element. The timer measures the time from the emission to the reception of the laser beam, thereby calculating the distance from the observer to the object to be measured. It can be often seen in engineering cost. Many existing laser rangefinders for engineering cost are mostly handheld laser rangefinders. The stability of handheld positioning of laser rangefinders is poor, which affects the accuracy of measurement. Therefore, the laser rangefinder must be fixed and positioned with the help of a positioning device. For example, a laser rangefinder positioning device with Chinese patent application number CN202221778974.9 shows a setting method that uses a movable rod, a support leg, a positioning hole and a bolt to cooperate. By moving the movable rod to slide at the bottom of the support leg, the position of the movable rod is adjusted, and then the bolt is turned to slide one end of it into the inner cavity of one of the positioning holes, the movable rod is fixed, and the height of the rangefinder is changed, which is convenient for the use of the rangefinder.

[0003] However, when the laser rangefinder is used for positioning, it is necessary to manually rotate the movable rod around the mounting base to open it, and when the laser rangefinder is positioned and fixed, this process can easily cause the three supporting legs to be not on the same horizontal plane, causing the three supporting legs to tilt or even fall, affecting the normal use of the laser rangefinder. Utility Model Content

[0008] Furthermore, the adjustment assembly includes a threaded rod arranged in a fixed column for rotation, and a bevel gear 2 for meshing with a bevel gear 1 is fixedly mounted on the rod body of the threaded rod.

[0009] Furthermore, the positioning assembly includes a fixing ring fixedly mounted on a fixing column, the ring body of the fixing ring is movably connected with a support rod for supporting the fixing column, and there are three support rods, and the bottom end of the support rod is provided with an articulated block 1 for hinged connection with the support assembly.

[0010] Furthermore, the support assembly includes a threaded sleeve plate threadedly connected to the threaded rod, and a hinge block 2 is fixedly installed on the plate body of the threaded sleeve plate, and there are three hinge blocks 2. The hinge block 2 is movably connected with a hinge rod for hinged connection with the hinge block 1.

[0011] Furthermore, a placement frame for placing the laser rangefinder body is fixedly installed on the top of the fixed column, and a column is fixedly installed on the top of the placement frame, and there are two columns.

[0012] Furthermore, a movable plate for moving up and down is arranged in the column, a spring for resetting the movable plate is arranged in the column, a pressure plate for pressing the laser rangefinder body is fixedly installed between the two movable plates, and a handle for driving the pressure plate to move up and down is fixedly installed on the top of the pressure plate.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] By arranging the positioning device, when it is necessary to perform engineering distance measurement on the laser rangefinder body on the fixing device, the rotating shaft can be driven to rotate by the hand wheel, and under the meshing connection of the bevel gear 1 and the bevel gear 2, the threaded rod can be rotated, and the threaded sleeve plate can be moved up and down along the threaded rod, so that the hinged rod can be driven to drive the support rod to rotate, and the three support rods can be synchronously unfolded and stored, and the three support rods are always in the same horizontal plane, so as to solve the problem of the three support rods being skewed or even tipped over, and thus it is beneficial to the normal use of the laser rangefinder body.
