[0024] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] Embodiment 1

[0026] like Figures 1 to 4 As shown, this embodiment provides a safety pressure rod structure, including: a seat back plate 1; a transmission mechanism 2; the transmission mechanism 2 can be rotatably set on the seat back plate 1; a pressure rod 3; the pressure rod 3 is set on the transmission mechanism 2; a locking mechanism 4; one end of the locking mechanism 4 is rotatably set on the seat back plate 1, and the other end of the locking mechanism 4 is connected to the transmission mechanism 2; an unlocking mechanism 5; one end of the unlocking mechanism 5 is rotatably set on the seat back plate 1, and the other end of the unlocking mechanism 5 is connected to the locking mechanism 4; a reset member 6; one end of the reset member 6 is connected to the seat back plate 1, and the other end of the reset member 6 is connected to the transmission mechanism 2.

[0027] In this embodiment, the pressure rod 3 is used to limit the range of human movement on the seat back plate 1, which plays a role in safety protection for the human body; the pressure rod 3 is installed on the transmission mechanism 2, and the transmission mechanism 2 can drive the pressure rod 3 to rotate upward or downward. The safety pressure rod structure has two use states, wherein:

[0028] ① In the no-load (no-one) state, the unlocking mechanism 5 is manually controlled to lift the locking mechanism 4, and the locking mechanism 4 is separated from the transmission mechanism 2. The transmission mechanism 2 rotates upward under the driving action of the reset member 6, thereby driving the pressure rod 3 to rotate upward and open;

[0029] ② In the state of carrying people, release the unlocking mechanism 5 and manually control the pressure rod 3 to rotate downward, the pressure rod 3 drives the transmission mechanism 2 to rotate downward, at this time the locking mechanism 4 and the transmission mechanism 2 abut against each other, after releasing the pressure rod 3, the transmission mechanism 2 cannot rotate upward under the locking action of the locking mechanism 4, so that the pressure rod 3 is kept in a fixed position, achieving the safety protection effect of the human body on the seat back plate 1;

[0030] The safety pressure rod structure can realize the locked state of the pressure rod 3 in the manned state, or the open state of the pressure rod 3 in the unmanned state by manually controlling the unlocking mechanism 5 and the pressure rod 3. Compared with the pneumatic locking, hydraulic locking or electric locking methods in the prior art, the structure of the present application is simpler, more convenient to use and has lower production cost.

[0031] Furthermore, the transmission mechanism 2 includes: a rotating shaft 21, a ratchet 22 and a transmission member 23; the rotating shaft 21 is rotatably set on the seat back plate 1; the pressure rod 3 is installed on the rotating shaft 21; one end of the ratchet 22 is set on the rotating shaft 21, and the other end of the ratchet 22 is connected to the locking mechanism 4; one end of the transmission member 23 is set on the rotating shaft 21, and the other end of the transmission member 23 is connected to the reset member 6.

[0032] In this embodiment, the rotating shaft 21 is rotatably arranged on the seat back plate 1, the ratchet 22 and the transmission member 23 are respectively installed at the two sides of the rotating shaft 21, the ratchet 22 and the locking mechanism 4 abut against each other, and the transmission member 23 is connected to the reset member 6;

[0033] ① In the no-load (no-one) state, the locking mechanism 4 is separated from the ratchet 22, and the transmission member 23 is reset under the rebound action of the reset member 6, so that the transmission mechanism 2 rotates upward and opens the pressure rod 3;

[0034] ② In the manned state, release the unlocking mechanism 5 and manually control the pressure rod 3 to rotate downward, the locking mechanism 4 abuts against the ratchet 22, so that the transmission mechanism 2 can only rotate downward but not upward, and the pressure rod 3 remains in a fixed position to achieve a safe locking effect.

[0035] Furthermore, a square sleeve is provided on the outer side of the rotating shaft 21; the pressure rod 3, the ratchet 22 and the transmission member 23 are all mounted on the square sleeve.

[0036] In this embodiment, the square sleeve is arranged on the outside of the rotating shaft 21, and the pressure rod 3, ratchet 22 and transmission member 23 are all installed on the square sleeve. The square sleeve can make the movement synchronization rate between the rotating shaft 21 and the pressure rod 3, ratchet 22 and transmission member 23 higher to prevent slipping.

[0037] Furthermore, the locking mechanism 4 includes: a locking rod 41 and a return spring 42; one end of the locking rod 41 is rotatably set on the seat back 1 and abuts the ratchet 22, and the other end of the locking rod 41 abuts the unlocking mechanism 5; one end of the return spring 42 is connected to the locking rod 41, and the other end of the return spring 42 is connected to the seat back 1.

[0038] In this embodiment, the middle part of the locking rod 41 is rotatably arranged on the seat back plate 1. In the locked state, the inner side of the locking rod 41 abuts against the ratchet 22, the upper end of the locking rod 41 abuts against the unlocking mechanism 5, and the lower end of the locking rod 41 is connected to the seat back plate 1 through the return spring 42, and the return spring 42 is in a stretched state; in the unlocked state, a force is manually applied to the unlocking mechanism 5, the unlocking mechanism 5 rotates and lifts up the upper end of the locking rod 41, the inner side of the locking rod 41 is separated from the ratchet 22, and the return spring 42 is in a compressed state. When the force is no longer applied to the unlocking mechanism 5, the return spring 42 lifts up the lower end of the locking rod 41, and the inner side of the locking rod 41 abuts against the ratchet 22 again (see Figure 2 and Figure 3 ).

[0039] Furthermore, ratchet teeth corresponding to and matching the ratchet wheel 22 are provided on the locking rod 41 .

[0040] In this embodiment, a ratchet is provided on the inner side of the locking rod 41, and the locking rod 41 is meshed with the ratchet 22 through the ratchet. When the locking rod 41 abuts against the ratchet 22, the ratchet 22 can only rotate in one direction, so that the transmission mechanism 2 connected to the ratchet 22 can only rotate in one direction, thereby achieving a locking effect; when the locking rod 41 is separated from the ratchet 22, the transmission mechanism 2 rotates in the opposite direction and resets under the action of the reset member 6, and the pressure rod 3 opens upward.

[0041] Furthermore, the unlocking mechanism 5 includes: a rotating rod 51 and a push rod 52 ; the rotating rod 51 is rotatably arranged on the seat back plate 1 ; one end of the push rod 52 is arranged on the rotating rod 51 , and the other end of the push rod 52 abuts against the locking rod 41 .

[0042] In this embodiment, the rotating rod 51 is rotatably set at the upper end of the seat back plate 1, and the push rod 52 is installed on the rotating rod 51 and abuts against the locking rod 41. When the rotating rod 51 is manually rotated, the locking rod 41 can be pushed away by the push rod 52, so that the locking rod 41 no longer abuts against the ratchet 22. At this time, the transmission mechanism 2 rotates and resets under the action of the reset member 6, driving the pressure rod 3 to open upward.

[0043] Furthermore, push-pull handles 53 are provided at both ends of the rotating rod 51 for driving the rotating rod 51 to move.

[0044] In this embodiment, two push-pull handles 53 are respectively arranged at both ends of the rotating rod 51 for manual operation by the staff. The push-pull handles 53 can increase the torsion arm of the rotating rod 51, thereby making it more convenient for the staff to drive the rotating rod 51.

[0045] Furthermore, an arc-shaped protrusion is provided at the top end of the locking rod 41 ; and an arc-shaped groove is provided at the top end of the push rod 52 .

[0046] In this embodiment, an arc-shaped protrusion is provided at the top end of the locking rod 41, and an arc-shaped groove is provided at the top end of the push rod 52. The locking rod 41 and the push rod 52 are abutted against each other through the arc-shaped protrusion and the arc-shaped groove, so that the push rod 52 can push the locking rod 41 open more smoothly.

[0047] Furthermore, the reset member 6 is a nitrogen spring.

[0048] In this embodiment, the reset member 6 is a nitrogen spring, which is normally in an extended state. Therefore, after the device is unlocked, the nitrogen spring is reset to the extended state, thereby pushing the transmission mechanism 2 to rotate upward through the transmission member 23.
