For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
[0027] The utility model discloses a seat anti -toppling mechanism for the production flow line of car seat 90. In the circulation process between different production procedures of car seat 90, car seat 90 needs to be circulated from one station to another or more stations, and at present, car seat 90 is mainly transported through the mode of conveying belt 80, when the conveying direction is switched, that is, at the corner position of conveying belt 80, car seat 90 is easy to overturn due to unstable gravity center.
[0028] Referring to Figures 1-4The utility model includes: a main frame 10, a synchronous belt moving mechanism 20, a driving device 30 (preferably a driving motor in this embodiment) and an anti-fall bar 40. Among them, the main frame 10 provides support and installation for the various components of the anti-fall machine; the synchronous belt moving mechanism 20 includes a transmission wheel 21 and a horizontally arranged synchronous belt 22, and the synchronous belt 22 and the transmission wheel 21 are engaged with each other for transmission. The driving device 30 is transmission-connected to the transmission wheel 21, and is used to drive the synchronous belt 22 to perform linear reciprocating motion. The anti-fall bar 40 specifically includes a connecting rod body 41 and a limiting rod body 42, one end of the connecting rod body 41 is fixedly connected to the synchronous belt 22, and the other end is fixedly connected to the limiting rod body 42; the limiting rod body 42 is horizontally arranged, and is used to support the rear of the backrest of the car seat 90. The car seat 90 is first moved along a first horizontal direction ( Figure 1 The anti-fall bar 40 is located behind the backrest of the car seat 90; the synchronous belt 22 is rotated along the second horizontal direction (the direction of the arrow D1 shown in FIG. Figure 1 The second horizontal direction (D2) and the first horizontal direction (D1) are arranged and produce linear movement, and the second horizontal direction (D2) and the first horizontal direction (D1) are perpendicular to each other.
[0029] The working principle of this utility model is as follows: Figure 1 When switching the workstation, the car seat 90 is conveyed along the first horizontal direction (i.e. Figure 1 The direction of the arrow D1 is shown) and is transported to the bottom of the main frame 10. At this time, it is necessary to switch to the second horizontal direction ( Figure 1 During the switching of the conveying direction, the anti-fall bar 40 is located behind the backrest of the car seat 90. The driving device 30 drives the transmission wheel 21 to rotate, and the synchronous belt 22 moves linearly along the second conveying direction, driving the anti-fall bar 40 to move forward along the second conveying direction. The limiting rod body 42 of the anti-fall bar 40 pushes the car seat 90 forward. During the conveying process, if the center of gravity of the car seat 90 is unstable and there is a tendency for it to fall backward, it will be limited by the anti-fall bar 40, so that the car seat 90 always maintains an upright posture during the conveying process, preventing the car seat 90 from being damaged in quality due to tipping over and the subsequent accumulation of workpieces, thereby ensuring the quality of the car seat 90 and the flow efficiency on the production line.

When the synchronous belt 22 drives the anti-falling rod 40 to move straightly, the guiding slide block 52 slides along the guiding slide rail 51, thereby enhancing the guiding stability.
