Abstract
A canvas tensioning mechanism for a cot has a support component (2) which has a first support rod (21) and a second support rod (22) respectively extending toward two sides of the canvas; a fixed fastener (3) is disposed on the top of the first support rod (21) and is capable of being buckled on one of the two side rods (1); a movable fastener (4) is rotatably disposed on the top of the second support rod (22) and is capable of being buckled on the other side rod (1). A leisure bed has a piece of canvas, two side rods and at least two canvas tensioning mechanisms. The canvas tensioning mechanism can easily tension and mount the canvas by a small force, and is convenient to tension the canvas and high in tightness.
Claims7
A canvas having a tensioning mechanism for a cot, the cot comprising two side rods (1) disposed at two sides of the canvas, the tensioning mechanism comprising a support component (2), a fixed fastener (3), and a movable fastener (4);
- wherein,
- the tensioning mechanism is configured to receive the two side rods (1);
- the support component (2) has a first support rod (21) and a second support rod (22) each having a top, respectively extending toward two sides of the canvas;
- the fixed fastener (3) is disposed on the top of the first support rod (21) and is configured to be buckled on one of the two side rods (1);
- the movable fastener (4) is rotatably disposed on the top of the second support rod (22) and is configured to be buckled on the other of the two side rods (1);
- and the movable fastener (4) is configured to rotate in a direction which increases tension on the canvas and causes clamping on the second support rod (22);
- wherein
- the movable fastener (4) comprises a main body (41) rotatably connected to the second support rod (22) and a buckling portion (42) connected to the top of the main body (41);
- the buckling portion (42) has a clamping groove (421) for receiving the side rod (1);
- the main body (41) has an accommodating groove (411) for receiving the second support rod (22), and the main body (41) clamps on the second support rod (22) after the canvas is tensioned;
- first and second elastic limiting protrusions (5) respectively biased towards opposing sidewalls of the accommodating groove (411) are disposed on the second support rod (22), correspondingly, the main body (41) has first and second staggered limiting holes (412) respectively located on the opposing sidewalls of the accommodating groove (411) for respectively receiving the first and second limiting protrusions (5)
- the second support rod (22) is a hollow pipe, and a mounting block (7) for receiving the elastic limiting protrusions (5) is disposed inside the second support rod (22);
- the mounting block (7) has a plurality of mounting recesses (71) for mounting the elastic limiting protrusions (5), and an elastic piece (6) is disposed inside each mounting recess (71) pushing each limiting protrusion (5) to protrude out of the second support rod (22).
