[0014] The present invention will now be described in further detail with reference to the accompanying drawings.

[0015] like Figure 1-3As shown, a laser rangefinder of this utility model includes a base 1. A horizontal T-shaped lead screw 2 and two sets of sliding lower rails 11 extending forward and backward are installed on the top of the base 1 (a pad can be set under the sliding lower rail 11 as needed). The two sets of sliding lower rails 11 are located at the front and rear ends of the base 1, and the two sliding lower rails 11 in each set are located on the left and right sides of the T-shaped lead screw 2 respectively.

[0016] A front deflector assembly 3 is slidably mounted on a set of lower sliding rails 11 at the front end, and a rear deflector assembly 4 is mounted on a set of lower sliding rails 11 at the rear end. Both the front deflector assembly 3 and the rear deflector assembly 4 are connected to the T-shaped lead screw 2 and can slide back and forth within a certain range along the lower sliding rails 11 under the operation of the lead screw 2.

[0017] The front windshield assembly 3 includes a front slide 31, which is slidably mounted on the lower slide rail 11 and connected to the T-shaped lead screw 2. A front stop block 32 is slidably mounted on the top of the front slide 31 via an upper slide rail 35 that extends back and forth. A front support plate 33 is connected to the rear side of the front slide 31, and a front notch 34 is provided on the top of the front support plate 33.

[0018] In addition, a laser 5 is connected to the front side of the base 1. The laser 5 is directed toward the front stop 32 and can measure the sliding distance of the front stop 32.

[0019] Preferably, the laser 5 is mounted on a pad 51, and a set of sliding rails 11 located in front and the front bumper assembly 3 thereon can also be mounted on the pad 51.

[0020] The rear stop assembly 4 includes a rear slide 41, which is slidably mounted on the lower slide rail 11 and connected to the T-shaped lead screw 2. A rear stop block 42 is fixedly mounted on the top of the rear slide 41. The rear stop block 42 and the front stop block 32 are located on the same horizontal line. A rear support plate 43 is connected to the front side of the rear slide 41. A rear notch 44 is provided on the top of the rear support plate 43. The front notch 34 and the rear notch 44 are both located on the same horizontal line and can jointly support the pipe 7 to be tested.

[0021] Preferably, a lifting cylinder 6 is also installed on the rear side of the front support plate 33. A lifting block 61 is connected to the top piston rod of the lifting cylinder 6. A lifting notch 62 is provided on the top of the lifting unloading block. The lifting notch 62 can be raised to a position higher than the front notch 34 and the rear notch 44. The operation of the lifting cylinder 6 can drive the lifting unloading block to rise, and lift the pipe 7 supported on the front notch 34 and the rear notch 44 through the lifting notch 62 for unloading.

[0022] When using this laser rangefinder, the pipe 7 and other materials are installed on the front notch 34 and the rear notch 44. The front stop 32 slides backward so that the front stop 32 and the rear stop 42 can clamp the two ends of the pipe 7 together. The laser 5 measures and records the moving distance of the front stop 32. The length of the pipe 7 is obtained by subtracting the measured distance from the pre-stored data before the movement. Finally, the pipe 7 can be unloaded using the lifting cylinder 6 and the lifting block 61.

[0023] When the length of the pipe 7 varies greatly, the front guard assembly 3 and the rear guard assembly 4 can be slid back and forth as needed to adapt to the distance measurement requirements of materials of different lengths.

[0024] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
