[0020] See also Figure 1-Figure 3A vehicle-mounted simple pull-out ladder comprises a first support frame 1, a slide groove is provided on the left side of the first support frame 1, a second support frame 11 is slidably arranged in the slide groove, a group of support feet 13 are rotatably arranged on the front and rear sides of the inner wall of the second support frame 11 through a rotating shaft, two groups of footrests 14 are evenly fixedly arranged between the two groups of support feet 13, a foot pedal 12 is fixedly arranged on the top of the second support frame 11, and anti-skid drainage holes 15 are evenly stamped on the top of the foot pedal 12 and the footrest 14, and anti-skid teeth 16 are provided on the left side of the top of the foot pedal 12 and the footrest 14. The first support frame 1 is fixed to the bottom of the vehicle by welding or bolting, and the ratchet 31 is clamped in the slot at the bottom of the slide groove of the first support frame 1, so as to complete the fixing of the second support frame 11. When a worker passes the footrest 14 and the foot pedal When the board 12 gets on and off the car, the anti-skid property can be effectively improved by the foot pedal 14 and the anti-skid drainage hole 15, thereby improving the safety of the device. A locking assembly is placed on the outer wall of the second support frame 11, and the locking assembly includes a pawl 31. Two groups of pawls 31 are respectively arranged on the front and rear sides of the second support frame 11 through a rotating shaft. A group of pulleys 32 are arranged on the front and rear sides of the second support frame 11 through a rotating shaft. The pulley 32 can assist the second support frame 11 to move conveniently in the slide groove of the first support frame 1. A group of support plates 3 are fixedly arranged on the front and rear sides of the second support frame 11. The bottom left side of the pawl 31 is located at the top of the support plate 3. Two groups of card slots are evenly opened at the bottom of the slide groove of the first support frame 1. The card head of the pawl 31 is clamped in the card slot, and the pulley 32 is rollingly arranged in the slide groove.

[0021] A support plate 2 is fixedly provided at the bottom of the first support frame 1. A guide hole is provided through the right side of the support plate 2. A guide rod 22 is slidably provided in the guide hole. A guide hole is provided through the left side of the guide rod 22 and a hook 21 is connected thereto. The hook 21 corresponds to the foot column 14. An external thread is provided on the right side of the outer wall of the guide rod 22. A nut 24 is screwed on the portion of the guide rod 22 with the external thread. A spring 23 is placed on the outer ring of the guide rod 22. The spring 23 is located between the support plate 2 and the nut 24. A lock hole is provided through the right side of the outer wall of the guide rod 22. A cotter pin 25 is inserted in the lock hole. The cotter pin 25 is located on the right side of the nut 24. When the device is idle, the support foot 13 is moved to the left side of the support leg 13. Flip it up and be flush with the second support frame 11, and then the second support frame 11 and the supporting foot 13 can be slid to the right and stored in the sliding groove of the first support frame 1. When the second support frame 11 moves to the right, it will drive the pawl 31 to move to the right. At this time, the pawl 31 is blocked by the slot and rotates counterclockwise to stagger with the slot, thereby completing the unlocking of the second support frame 11. When the second support frame 11 and the supporting foot 13 are stored in the first support frame 1, pull the hook 21 to the left and rotate it so that the hook 21 hooks the foot column 14, and then the rebound force of the guide rod 22 makes the hook 21 hook it tightly, so that the supporting foot 13 and the second support frame 11 can be fixedly stored in the first support frame 1.

[0022] Working principle: The first support frame 1 is fixed to the bottom of the vehicle by welding or bolting, and the ratchet 31 is clamped in the slot at the bottom of the slide slot of the first support frame 1 to complete the fixing of the second support frame 11. When workers get on and off the car through the foot column 14 and the foot pedal 12, the foot column 14 and the anti-skid drainage hole 15 can effectively improve the anti-skid property, thereby improving the safety of the device. When the device is idle, the support foot 13 is flipped upward to be flush with the second support frame 11, and then the second support frame 11 and the support foot 13 can be slid to the right for storage When the second support frame 11 moves to the right, the pawl 31 will move to the right. At this time, the pawl 31 is blocked by the slot and rotates counterclockwise to be offset from the slot, thereby completing the unlocking of the second support frame 11. When the second support frame 11 and the supporting foot 13 are stored in the first support frame 1, pull the hook 21 to the left and rotate it so that the hook 21 hooks the foot column 14, and then the rebound force of the guide rod 22 makes the hook 21 hook it tightly, so that the supporting foot 13 and the second support frame 11 can be fixedly stored in the first support frame 1.
