Description

Technical Field

[0001] The utility model relates to the technical field of surveying and mapping instruments, in particular to an anti-collision protection device for surveying and mapping instruments. Background Art

[0002] Surveying and mapping instruments, in simple terms, are instruments and devices designed and manufactured for surveying and mapping operations for data collection, processing, and output. In the planning, design, construction, and management stages of engineering construction, various instruments for orientation, distance, angle, height, mapping, and photogrammetry are required for surveying work. In order to facilitate anti-collision protection of surveying and mapping instruments, a surveying and mapping instrument anti-collision protection device is needed.

[0003] Many existing surveying and mapping instruments are not protected from collision by protective devices after use. Stones are easily dropped from construction sites, and the uneven ground of construction sites may cause the risk of the surveying and mapping instruments tipping over, which in turn may cause the risk of the surveying and mapping instruments being hit or smashed. Some surveying and mapping instrument anti-collision protection devices generally include two protective covers, which are fixedly connected by multiple bolts, and the surveying and mapping instrument is located inside the two protective covers, thereby achieving the effect of anti-collision protection. However, this type of bolted connection often requires the removal of multiple bolts when using the surveying and mapping instrument, which is extremely inconvenient to use. Therefore, it is necessary to propose an anti-collision protection device for surveying and mapping instruments to solve the above-mentioned problems. Utility Model Content

The upper end of the left protective cover is slidably connected to two sliding blocks distributed front and back through two sliding grooves. A frame is fixedly connected between the two sliding blocks. A limiting block is arranged inside the frame to be pressed against the upper end of the left protective cover. The upper end of the limiting block is rotatably connected to a screw that passes through the top of the inner wall of the frame and is threadedly connected to the frame. A limiting plate is fixedly connected to the upper end of the right protective cover. A limiting hole is penetrated through the left side of the limiting plate. A limiting rod that passes through the limiting hole and matches with the limiting rod is fixedly connected to the right side of the frame.

[0006] In order to improve the stability of the up and down movement of the limiting block, as a preferred anti-collision protection device for surveying and mapping instruments of the utility model, the limiting block is slidably connected to the front and rear sides of the inner wall of the frame through a sliding groove.

[0007] In order to facilitate the support and fixation of the fixed plate, as a preferred anti-collision protection device for surveying and mapping instruments of the utility model, the lower end of the fixed plate is fixedly connected with a connecting column, the lower end of the connecting column is fixedly connected with a disc, and the lower end of the disc is installed with three evenly distributed support rods.

[0008] In order to facilitate the rotation of the screw and to achieve an anti-slip effect when turning the knob, as a preferred anti-collision protection device for surveying and mapping instruments of the utility model, the upper end of the screw is fixedly connected to the knob, and the outer wall of the knob is provided with anti-slip patterns.

[0009] In order to improve the anti-slip performance of the limiting block, as a preferred anti-collision protection device for surveying and mapping instruments of the utility model, the lower end of the limiting block is made of rubber material.

[0010] In order to facilitate the limiting rod to enter the interior of the limiting hole, as a preferred anti-collision protection device for surveying and mapping instruments of the utility model, the right side of the limiting rod is a hemispherical structure.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] By making the two protective covers rotate relative to each other until they abut against each other, and then making the limit rod move to the right and enter the inside of the limit hole, the limit block is squeezed with the left protective cover, so that the movement position of the two sliding blocks can be limited, and because the limit rod and the limit hole match each other, the two protective covers are fixed in a limited position. At this time, the surveying and mapping instrument body is located inside the two protective covers, further achieving the effect of facilitating the anti-collision protection of the surveying and mapping instrument body;

[0013] By moving the limiting block upward and then moving the limiting rod leftward and out of the limiting hole, the two protective covers can be moved back to back, and the surveying instrument body can be used, further achieving the purpose of facilitating the disassembly of the two protective covers and quick and convenient use.
