[0026] Reference Figures 1 to 5 The pitch angle adjustable suspension assembly mainly comprises a suspension seat 1, a connecting seat 2 and a horizontal axis 3; the suspension seat 1 can be rotatably positioned on the connecting seat 2 through the horizontal axis 3, and a damping structure 4 and a locking device 5 are arranged between the suspension seat 1 and the connecting seat 2. The damping structure 4 comprises a friction wheel 41 arranged on one side of the suspension seat 1 and a damping plate 42 arranged on one side of the connecting seat 2, and the damping plate 42 is used to form a supporting force and adjust the damping force by friction with the end surface of the friction wheel 41.

[0027] The locking device 5 comprises a first friction block 51 and a second friction block 52 with inclined surfaces, and an adjusting bolt 53; more specifically, the contact surfaces of the first friction block 51 and the second friction block 52 are inclined surfaces, and an anti-dropping mortise and tenon structure 54 is arranged between the two inclined surfaces, and the two friction blocks are connected into one body by the mortise and tenon structure 54, and the inclined surface can be used to drive the first friction block 51 to move. The first friction block 51 is arranged in the slide groove 21 of the connecting seat, and the friction surface 511 is in contact with the circumferential surface of the friction wheel 41 on one side of the suspension seat, and has a larger resistance arm; in addition, the friction surface 511 is processed into an arc surface that matches the friction wheel 41, so as to increase the friction area and improve the friction force.

[0028] The second friction block 52 is threadedly matched with the adjusting bolt 53. The adjusting bolt 53 can be rotatably positioned on the connecting seat 2, and a knob 531 is fixed on the end passing through the connecting seat 2. Rotating the adjusting bolt 53 can drive the second friction block 52 to slide, and the first friction block 51 is driven by the matching inclined surface to press against the circumferential surface of the friction wheel 41 to generate locking. The adjusting bolt 53 can be rotatably positioned, specifically, the adjusting bolt 53 passes through the axial hole 22 of the connecting seat, and a shaft sleeve 23 is sleeved on the axial hole. The inner end of the adjusting bolt is positioned on the connecting seat 2 through the shaft pressure cover 24, and the outer end is screwed to lock the knob 531, which is convenient for locking and adjustment.

[0029] Furthermore, one end of the connecting seat 2 has an axle seat 25 and a central slot 26 separated on both side edges, and a damping plate 42 is arranged on both sides of the slot 26, and the damping plate 42 is constrained by the horizontal axis 3; the suspension seat 1 has two axle ears 11, and the two axle ears 11 are clamped on the outer sides of the two axle seats 25. The friction wheel 41 locked between the two axle ears 11 falls into the central slot 26 and is clamped by the two damping plates 42. The horizontal axis 3 also passes through the friction wheel 41 and both ends can be rotatably positioned in the axle ears 11.

[0030] A damping force adjustment block 43 is also provided between the damping plate 42 and the shaft seat 25. One side of the adjustment block 43 contacts the damping plate 42, and the other side away from the damping plate 42 is an inclined surface. The connection seat 2 is formed with a notch 27 capable of accommodating the adjustment block, and the notch 27 has an inclined side wall 271 that matches the inclined surface of the adjustment block. The adjustment block 43 is locked in the notch 27 by a screw 44, and during the tightening process of the screw 44, the adjustment block 43 can be pushed to squeeze one side of the damping plate 42 to increase the friction force between the damping plate 42 and the friction wheel 41. Only one adjustment block 43 is required to squeeze the damping plate 42 on one side, so that the friction wheel 41 produces an axial micro-shift, and also increases the squeezing force with the other damping plate.

[0031] Furthermore, two torsion springs 6 are arranged between the connecting seat 2 and the suspension seat 1 , and are distributed between the contacting parts of the two axle seats 25 and the axle ears 11 , so as to provide a supporting force of a predetermined angle.
