Telescopic plate

A telescopic plate comprising:

• a sliding rail structure comprising at least one fixed sliding rail and at least one telescopic sliding rail sliding within the fixed sliding rail;
• a drive structure comprising at least one motor;
• a rotation structure comprising at least one double-groove wheel mounted on an end of the motor;
• a circulation structure comprising an upper connection member and a lower connection member, both the upper connection member and the lower connection member wound around the at least one double-groove wheel and extending into the fixed sliding rail to be fixedly connected with the telescopic sliding rail;
• a support frame mounted on the telescopic sliding rail;
• a positioning bolt formed on an inner wall at a tail end of the fixed sliding rail and a positioning groove formed at a front portion of the telescopic sliding rail to engage with the positioning bolt;
• and wherein
• the upper connection member and the lower connection member are provided for pulling the telescopic sliding rail to drive the support frame to slide in the fixed sliding rail;
• and the positioning bolt and the positioning groove are cooperatively engaged with each other so that the telescopic sliding rail can rotate relative to the positioning bolt so as to slide and rotate the support frame relative to the fixed sliding rail;
• and where in
• a rotation angle of the telescopic sliding rail rotating round the positioning bolt is formed 0-100°;
• and wherein
• the circulation structure further comprises a guiding wheel fixed at a distal top end of fixed sliding rail, a swing arm and a sliding wheel fixedly connected with the telescopic sliding rail via the swing arm, the upper connection member passing through the guiding wheel and the sliding wheel in turn and then fixed with the telescopic sliding rail, and the lower connection member passing through the sliding wheel and then fixed with the telescopic sliding rail.
