[0028] This example provides a side ladder, based on Figures 1 to 4 as shown, including support body 1 and side ladder body 2. Among them, the support body 1 is the part for fixed installation, such as wall, support or chassis frame of vehicle, etc. The top of the side ladder body 2 is hinged with the support body 1. The side ladder body 2 can be changed into inclined state or vertical state by rotating. On the basis of the above structure, it also includes support frame 3, the support body 1 is provided with fixed assembly 4 and storage slot 101 opposite to the bottom end of the side ladder body 2, the opening bottom of the storage slot 101 has support rail 102, one end of the support frame 3 is hinged with the bottom end of the side ladder body 2, the other end of the support frame 3 is provided with notch 301 clamped on the support rail 102, the support frame 3 can be rotated and stored into the storage slot 101 and make the side ladder body 2 vertically arranged, when the side ladder body 2 is vertically arranged, the side ladder body 2 is detachably connected with the support body 1 through the fixed assembly 4.

[0029] The side ladder can be installed on a vehicle to facilitate climbing. During driving of the vehicle, the side ladder body 2 is in a storage state. At this time, the support frame 3 is placed in the storage groove 101, the side ladder body 2 is vertically placed and connected with the support body 1 through the fixing assembly 4 to avoid shaking and to avoid occupying lateral space by the side ladder body 2. When climbing is needed, the fixing assembly 4 and the side ladder body 2 are disassembled, the side ladder body 2 is manually pulled, the side ladder body 2 is rotated along the support body 1 to an inclined state, and the support frame 3 is moved out of the storage groove 101. The side ladder body 2 is fixed by rotating the support frame 3 to make the notch 301 clamped at the support rail 102. When the side ladder is used up, the side ladder body 2 is manually pulled, the notch 301 of the support frame 3 is disengaged from the support rail 102. At this time, the support frame 3 is rotated and inserted into the storage groove 101 by pushing the side ladder body 2, the side ladder body 2 is pushed to a vertical state, and the side ladder body 2 is fixedly connected with the support body 1 through the fixing assembly 4. Since the side ladder body 2 is inclined outward during climbing, the feet of the operator can fully step on the footboard of the side ladder body 2 and are not blocked by the chassis battery 5 in the vehicle chassis, so that the climbing is more stable and the safety is high. Moreover, the whole side ladder adopts a pure mechanical structure, and there is no part deeply inserted into the vehicle chassis and connected with the vehicle chassis, so that the structure is simple and convenient to install.

[0030] Of course, the side ladder of the embodiment can also be used in fixed places, such as climbing of a support and climbing of a wall surface. At this time, the support and the wall surface are used as the support body 1.

[0031] Further, based on Figures 1 to 4 As shown, the top of the support frame 3 is provided with a pedal 302, and the pedal 302 and the notch 301 are located on both sides of the rotating shaft of the support frame 3. By stepping on the pedal 302, the end of the support frame 3 with the notch 301 can be rotated upward. When the side ladder body 2 is used up, the side ladder body 2 is pulled out, the pedal 302 is stepped on to rotate the support frame 3, and the support frame 3 is inserted into the storage groove 101 by pushing the side ladder body 2, so that the support frame 3 does not need to be manually rotated, and the operation is convenient.

[0032] Preferably, the bottom end of the side ladder body 2 is provided with an extension frame 201 facing the storage groove 101, the support frame 3 is hinged with the extension frame 201, and the pedal 302 is located on the side of the side ladder body 2. At this time, the position of the pedal 302 does not exceed the side wall of the side ladder body 2 away from the support body 1, and the pedal 302 does not increase the width of the vehicle when the side ladder is installed on the vehicle.

[0033] Further, the bottom of the support frame 3 is provided with a protruding part 303, the bottom end of the protruding part 303 is provided with a limiting protrusion 304 extending away from the direction of the side ladder body 2, the support frame 3, the protruding part 303 and the limiting protrusion 304 form a gap 301. First, since the protruding part 303 extends downward from the bottom side of the support frame 3, the gap 301 is not opened to the inside of the support frame 3, and the strength of the support frame 3 is not weakened. At the same time, after the support frame 3 is clamped with the support rail 102, the protruding part 303 abuts against the bottom of the support rail 102, avoiding the upward rotation of the support frame 3 due to vibration and other factors when climbing the ladder, the gap 301 and the support rail 102 will not be separated during use, ensuring safety.

[0034] Further, based on Figure 1 , Figure 2 and Figure 5 , the side ladder body 2 is provided with a limiting hole 202, which can be provided on the L-shaped plate connected to the side of the side ladder body 2, or directly provided on the tread surface of the side ladder body 2.

The support table 401 is vertically provided with a through hole 405, and the fixing sleeve 402 is fixedly connected to the top of the support table 401 and is arranged in alignment with the through hole 405. The outer side wall of the limiting pin 403 is provided with a boss 406, the limiting pin 403 is arranged from the top through the fixing sleeve 402 and the through hole 405, the boss 406 abuts against the support table 401, the top of the fixing sleeve 402 is provided with an inner edge 407, the spring 404 is sleeved on the outer side of the limiting pin 403 and clamped between the inner edge 407 and the boss 406, and the top end of the limiting pin 403 is provided with a lifting part 408 extending out of the fixing sleeve 402. The lifting part 408 can be pulled upward to drive the limiting pin 403 to slide along the fixing sleeve 402. When the side ladder body 2 is stored, the lifting part 408 is pulled upward to make the limiting pin 403 move upward and retract into the through hole 405, the side ladder body 2 is pushed to make the limiting hole 202 rotate with the side ladder body 2 and align to the bottom side of the through hole 405, then the lifting part 408 is released, the limiting pin 403 extends out of the bottom end of the through hole 405 under the action of the spring 404 and gravity and is inserted into the limiting hole 202 to fix the side ladder body 2. The spring 404 can always press the limiting pin 403 in the limiting hole 202 to avoid disengagement due to vibration. When the side ladder body 2 needs to be used, the lifting part 408 is pulled upward to make the limiting pin 403 move upward and retract into the through hole 405, and the side ladder body 2 is pulled to unfold the side ladder body 2.

[0035] The top of the fixed sleeve 402 is screw-connected with a top cover 409, the top cover 409 is provided with a mounting hole 410, the top edge of the top cover 409 is used as the inner edge 407, the limiting pin 403 is arranged from the top through the mounting hole 410, and the pulling part 408 is screw-connected at the top end of the limiting pin 403. The structure is convenient for installation of the whole fixed assembly 4. The specific steps are as follows: the spring 404 is sleeved on the outer side of the limiting pin 403 from the top, the limiting pin 403 with the spring 404 is inserted into the inside of the fixed sleeve 402 from the top, then the top cover 409 is sleeved on the outer side of the limiting pin 403 from the top and screw-connected at the top end of the fixed sleeve 402, and finally the pulling part 408 is screw-connected at the top of the limiting pin 403. The reverse operation can be performed when disassembling.

[0036] Preferably, the pulling part 408 is spherical, which is convenient for hand holding and avoids scratching the hands.

[0037] Further, based on Figure 1 and Figure 2 It is shown that the foot pedal of the side ladder body 2 is provided with a handrail 203 extending downward, so as to climb and push the side ladder body 2. Since the handrail 203 extends downward, it will not exceed the surface position of the side ladder body 2, and when installed on the vehicle, it will not increase the width of the vehicle, and the position of the handrail 203 will not affect normal climbing.
