Abstract
A ranging rod for accident scene investigation includes a ranging rod body 1, pulleys 2, and a push rod 3, the pulleys 2 are arranged under the ranging rod body 1 at the left end and the right end, and the push rod 3 is connected with the middle part of the ranging rod body 1 through a telescoping structure. When the ranging rod is used, the length of the ranging rod body 1 and the push rod 3 can be adjusted, and the ranging rod body 1 can be directly pushed to move on the track formed by accident scene trace, so that the aim of fast measurement is achieved and the measurement accuracy can be effectively improved.
Description
Technical field
The present invention relates to a kind of for investigating the range finding instrument that the scene of a traffic accident uses on the spot.
Background technology
When the scene of a traffic accident is investigated on the spot, usually need to measure the multiple range data such as braking mark, spacing, collision distance, effectively to analyze accident, common chi tool is used to measure, not convenient during operation, and multiple range observation needs to measure along vestige track, standard rule tool cannot ensure degree of accuracy.
Summary of the invention
The present invention, in order to solve above technical deficiency, proposes a kind of chi tool directly can carrying out carrying out measuring with pulley and push rod, easy to use, ensures the degree of accuracy measured, increases work efficiency.
The present invention's adopted technical scheme of dealing with problems is: the telemeter rod that the scene of the accident investigates use on the spot is made up of telemeter rod, pulley, push rod.
Pulley is arranged at two ends, left and right below telemeter rod, is pulled out by pulley pull bar, telemeter rod can be made directly to carry out on the ground during use.
Push rod adopts Collapsible structure to be connected with in the middle part of telemeter rod, regulating pushing rod length as required during use.
Adopt said structure, during use, telemeter rod and push rod length are regulated, directly promote track that telemeter rod causes at scene of the accident vestige moves, reach the object of Quick Measurement, simultaneously effectively improve the precision measured.
accompanying drawing illustrates:
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is the telemeter rod structural representation that the scene of the accident investigates use on the spot.
embodiment:
1 telemeter rod in the drawings, 2 pulleys, 3 push rods.
As shown in Figure 1, the telemeter rod that this scene of the accident investigates use on the spot is made up of telemeter rod 1, pulley 2, push rod 3.
Pulley 2 is arranged at two ends, left and right below telemeter rod 1, and pulled out by pulley pull bar during use, telemeter rod 1 can be made directly to carry out on the ground, and push rod 3 adopts Collapsible structure to be connected with in the middle part of telemeter rod 1, as required regulating pushing rod 3 length.
During use, telemeter rod 1 and push rod 3 length are regulated, directly promote track that range finding 1 causes at scene of the accident vestige moves, effectively improve the precision measured, reach the object of Quick Measurement.
