Abstract
A structure for adjusting an angle of a pedal to be folded or unfolded includes a pedal seat, a rotating block and a locking element, wherein the pedal seat includes an upright post with a through lug, and the through lug is provided with a through hole, the rotating block includes a pivot hole to provide the through lug passing through and corresponding to the through hole, the rotating block and the upright post are provided with at least one contact surface, the rotating block and the upright post are respectively provided with at least one matched clamping structure to be correspondingly clamped at the at least one contact surface, the rotating block and the upright post are clamped by the locking element, so that matched clamping structures of the rotating block and matched clamping structures of the upright post are together engaged in a pairwise manner.
Claims
1. A structure for adjusting an angle of a pedal to be folded or unfolded, comprising: a pedal seat, comprising an upright post with a through lug, wherein the through lug is provided with a through hole passing through the through lug; a rotating block, comprising a pivot hole to provide the through lug passing through and corresponding to the through hole, wherein the rotating block and the upright post are provided with at least one contact surface, and the rotating block and the upright post are respectively provided with at least one matched clamping structure to be correspondingly clamped at the at least one contact surface; and a locking element, passing through the through hole and the pivot hole, so that the rotating block is pivoted to the upright post and rotated to an upright position or a bending position, the rotating block and the upright post are clamped by the locking element so that the at least one matched clamping structure of the rotating block and the at least one matched clamping structure of the upright post are together engaged in a pairwise manner.
2. The structure according to claim 1, wherein the upright post comprises two uprights, the through lug comprises two sub-through-lugs respectively disposed on the two uprights, and the through hole comprises two sub-through-holes respectively disposed on the two sub-through-lugs.
3. The structure according to claim 2, wherein the rotating block comprises a pivot block extending between the two uprights, and the pivot hole is formed in the pivot block.
4. The structure according to claim 3, wherein the locking element comprises a bolt and a rotary knob, and the bolt passes through the through hole and the pivot hole to be screwed on the rotary knob.
5. The structure according to claim 4, wherein the bolt is threaded through a baffle adjacent to the rotary knob.
6. The structure according to claim 4, wherein a flange is provided in the pivot hole, the bolt is provided with two compression springs which are respectively located at both sides of the flange, and the two compression springs are pressed against both sides of the flange to press the two through lugs and drive the two uprights moving in a direction opposite to the flange.
7. The structure according to claim 1, wherein the rotating block comprises an locking tube disposed upwardly when in the upright position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
(6) The technical summary, features and efficacy of the present invention will be presented from the following detailed description of the preferred embodiments, taken in conjunction with the accompanying drawings.
(7) Referring to
(8) The rotating block 20 includes a pivot hole 21 to provide the through lug 12 passing through and corresponding to the through hole 13, the rotating block 20 and the upright post 11 are provided with at least one contact surface 40, the rotating block 20 and the upright post 11 are respectively provided with at least one matched clamping structure 50 to be correspondingly clamped at the at least one contact surface 40. In an embodiment, the upright post 11 may have two uprights 111, the through lug 12 includes two sub-through-lugs 121 respectively disposed on the two uprights 111, and the through hole 13 comprises two sub-through-holes 131 respectively disposed on the two sub-through-lugs 121, and the rotating block 20 includes a pivot block 22 extending between the two uprights 111, and the pivot hole 21 is formed in the pivot block 22.
(9) The locking element 30 passes through the through hole 13 and the pivot hole 21, so that the rotating block 20 is pivoted to the upright post 11 and rotated to an upright position or a bending position. When the rotating block 20 rotates to the upright position or the bending position, the rotating block 20 and the upright post 11 are clamped by the locking element 30, so that matched clamping structures 50 of the rotating block 20 and matched clamping structures 50 of the upright post 11 are together engaged in a pairwise manner. In an embodiment, the locking element 30 includes a bolt 31 and a rotary knob 32, and the bolt 31 passes through the through hole 13 and the pivot hole 21 to be screwed on the rotary knob 32.
(10) Referring to
(11) Referring to
(12) In summary, the invention has at least the following characteristics.
(13) 1. The rotating block and the upright post are clamped by the locking element. When the pedal is in a folded state or an unfolded state relative to the musical instrument stand, an angle between the rotating block and upright post is fixed through the engagement of the matched clamping structures 50 of the rotating block 20 and the matched clamping structures 50 of the upright post 11 in a pairwise manner.
(14) 2. The pedal is horizontally folded relative to the musical instrument stand, so that the problem of damage caused by falling down is avoided.
