Claims

[Scope of Claim for Utility Model Registration] (a) A metal plate is bent into a mountain shape to form a front plate and a back plate that stand upright, and the back plate has an appropriate width and height. (b) A tire barrier body having an inclined wall surface, (b) made of a rectangular pipe material of an appropriate diameter and length with both ends open, and provided with a ball fitting hole into which a ball fits in an appropriate part of the lower surface; a guide fitting tube located near the top of the inner surface and fixed horizontally; (c) one end fixed to the bottom surface of the guide fitting tube so as to elastically open and close the fitting hole; Opening/closing plate made of spring plate, (
d) A lock whose key hole is exposed on the surface of the top plate of the barrier body and is fixed to the top plate, and the key stick is rotated forward and backward with a key; (e) The tip of the key stick of the lock. (f) an operating rod of an appropriate length, which is attached to the key rod, and whose tip is configured to come into contact with and separate from the opening/closing plate at the ball fitting hole by rotating the key rod in the forward and reverse directions; A holding arm rod is formed by bending its tip inward at an appropriate angle to form an engaging piece, and is positioned near the top of the barrier body and fixed to one side surface of the back plate. ,(to)
It is formed to slidably fit into the guide fitting tube, and has an arbitrary number of spherical fitting recesses formed at appropriate intervals on the lower surface into which a part of the ball is rotatably fitted. At the tip of the sliding rod, a holding arm is formed symmetrically with the holding arm and extending in a perpendicular direction, and the sliding rod is fitted into the guide fitting tube. A sliding lock body is provided, and the rubber part of the tire is held from both sides by the holding arms, and the rubber part of the tire is held from both sides of the holding arm, and is inserted into the spherical fitting recess of the sliding stick through the ball fitting hole of the guide fitting tube. A tire locking device characterized in that the tire is locked by blocking the sliding of a sliding rod by an engaged ball.
