Abstract

The invention relates to an automatic positioning marking pole, wherein the main body of the marking pole body comprises a hollow marking pole, a marking pole spring, a positioning plate and a base, wherein one end of the hollow marking pole is connected with the positioning plate; the positioning plate is connected with an end surface of the base; one end of the marking pole spring is connected with the base after penetrating through the positioning plate; and the other end of the marking pole spring extends to and is fixed in the hollow marking pole. The automatic positioning marking pole is characterized by further comprising a shock-proof spring; at least two positioning holes are arranged on the end surface of the positioning plate; the shock-proof spring is arranged in the positioning hole; and the shock-proof spring is connected with the base. The marking pole is little in swing amplitude, short in rod stopping time, and safe and reliable in use.

Description

technical field [0001] The invention relates to an automatic positioning pole. Background technique [0002] At present, in the driver's pile test, some existing suspension rod automatic reset devices use magnets or pure spring devices on the upper part of the suspension rod, and some also install springs on the lower part of the rod. Just cause car body damage once, serious case, can cause car glass to break, personnel is injured. [0003] The existing device can only be hoisted on the gantry. Therefore, a single-arm and double-arm gantry must be equipped, which increases the investment cost, and the device can only be used in pile testing. [0004] The existing device has a large swing range of the suspension rod due to a large reaction force, a long time for stopping the rod, and is unsafe to use; the connection between the rod and the base is not strong due to insufficient pulling force, so the range of use is small. Contents of the invention [0005] The object of t...
