Abstract
The invention discloses a portable measurement device for relative displacement of a top board and a bottom board of a mine laneway. A top plate is arranged at the upper end of a flexible pipe. A bottom plate is arranged at the lower end of a sleeve. The lower end of the flexible pipe protrudes into the upper end of the sleeve and can slide flexibly in a free manner. A spring is arranged between the inner bottom face of the sleeve and the bottom face of the flexible pipe. Scales are arranged on the surface of the flexible pipe. The upper end of the flexible pipe is provided with a press button fitting with the upper end of the flexible pipe so as to retain the flexible pipe in the sleeve or enable the flexible pipe to protrude outside the sleeve due to the elastic force of the spring. According to the invention, the flexible pipe with the scales is connected to the sleeve through the spring, due to the elasticity of the spring, the flexible pipe can move freely in the sleeve, so that the distance between the bottom board and the top board of the mine laneway can be changed in a self-adaptive manner. Besides, when not in use, the flexible pipe can retract into the sleeve through spring compression, so that the size is reduced and carrying convenience is achieved.
