[0025] This embodiment uses a pull-out boarding ladder for the bulletproof shielded container, such as... Figure 1 As shown, the boarding ladder assembly is installed at the stern of the container, including a guide rail 1 and a step 2 that slides along the guide rail 1. The two side walls of the step 2 in the width direction slide on the guide rail 1 by sliders, thereby adjusting the relative position of the step 2 on the guide rail 1. The bottom of the guide rail 1 is provided with a groove 3 that is recessed into the bottom of the container. The groove 3 is used to accommodate the step 2. After the step 2 is flipped on the guide rail 1, it is folded into the groove 3 to reduce the longitudinal space occupied by the step 2.

[0026] Specifically, in combination Figure 2The guide rail component 1 includes a folding section 101 and a translation section 102 that is connected to the folding section 101 by an arc transition. The folding section 101 is located in the groove 3, that is, the translation section 102 is embedded in the bottom plate inside the container. The folding section 101 extends from the bottom plate inside the container along the inner side wall of the groove 3 into the groove 3.

[0027] The end of the folding section 101 away from the translation section 102 is connected to a bracket 5 that corresponds to the movement of the folding section 101. The bracket 5 is located at the end of the folding section 101 in the width direction. The bracket 5 is adapted to the folding section 101 and its two ends are correspondingly hinged to the two ends of the end of the folding section 101. The end of the bracket 5 away from the folding section 101 is connected to a pull bracket 6. The two sides of the pull bracket 6 away from the bracket 5 are hinged to the two side walls of the step 2 in the width direction. The pull bracket 6 can pull the step 2 to slide along the guide rail 1. Push rods 7 are connected to the two side walls of the folding section 101 facing the bracket 5. The output ends of the two push rods 7 are correspondingly connected to the two side walls of the bracket 5.

[0028] The push rod 7 adopts an electric push rod or hydraulic rod structure. When it is necessary to pull and retract the ladder 2, the output end of the push rod 7 extends and drives the bracket 5 to rotate around the end of the folding section 101. The bracket 5 drives the pull frame 6 to slide the ladder 2 along the translation section 102 onto the folding section 101. As the output end of the push rod 7 continues to extend, the connection end of the bracket 5 and the pull frame 6 is in a state that is almost perpendicular to the end of the folding section 102 in the groove 3. At this time, the ladder 2 is pulled and slid onto the folding section 102. The ladder 2 is gradually stored and fixed in the groove 3 without affecting the shape of the container. When it is necessary to extend and open the ladder 2, the output end of the push rod 7 retracts and lowers the bracket 5 to a position close to the folding section 102. The pull frame 6 and the ladder 2 unfold and are located in a straight line. The guide rail 1 ensures the lifting trajectory of the ladder 2. It occupies little space. When the boarding ladder 2 is in use, it is directly hidden inside the groove 3 without the need for additional loading. Example 2

[0029] This embodiment uses a pull-out boarding ladder for the bulletproof shielded container, such as... Figure 1 As shown, the device includes a guide rail 1 and a step 2 that slides along the guide rail 1. The two side walls of the step 2 in the width direction slide on the guide rail 1 via sliders, thereby adjusting the relative position of the step 2 on the guide rail 1. The bottom of the guide rail 1 is provided with a groove 3 that is recessed into the bottom of the cabin. The groove 3 is used to accommodate the step 2. After the step 2 is flipped on the guide rail 1, it is folded into the groove 3 to reduce the longitudinal space occupied by the step 2.

[0030] Combination Figure 3 and Figure 4The outer walls on both sides of the tread 2 are also connected to handrails 4 that are movable relative to the tread 2. The handrails 4 are parallel to the length direction of the tread 2. The handrails 4 are connected to the tread 2 through several evenly arranged support rods 8. The two ends of the support rods 8 are respectively hinged to the opposing surfaces of the tread 2 and the handrails 4.

[0031] The stair treads 2 and handrail 4 are provided with positioning components at their ends to determine the distance between the handrail 4 and the stair treads 2. The positioning components include a stop sleeve 12 sleeved on the support rod 8 and a guide groove 9 at the bottom of the handrail 4. The guide groove 9 has an L-shaped structure and a stop 10 adapted to the stop sleeve 12 is provided in the guide groove 9. The guide groove 9 has space for the stop 10 to move. The stop 10 is connected to the handrail 4 via a spring post 13 towards the top of the handrail 4. One end of the stop 10 is engaged in the guide groove 9 and slides in the guide groove 9, while the other end of the stop 10 is outside the guide groove 9.

[0032] The bottom of the baffle 10 located inside the guide groove 9 is connected to the limiting post 11. The stop sleeve 12 is provided with a relief hole 81 corresponding to and adapted to the limiting post 11. The end of the stop sleeve 12 is rounded to facilitate the limiting post 11 to slide smoothly into or out of the relief hole 81.

[0033] After the ladder 2 is pulled out of the cabin, the handrail 4 can be pulled up to be parallel to the ladder 2, so that people can hold the handrail when going up and down, thus reducing the possibility of falling. During the process of the handrail 4 being pulled up, the limiting post 11 gradually slides into the clearance hole 81. At this time, the stop 10 falls in the guide groove 9. The limiting post 11 and the clearance hole 81 form a blocking and locking structure, so that the relative position of the handrail 4 and the ladder 2 remains stable. When it is necessary to lower the handrail 4, the stop 10 is slid towards the handrail 4 until the limiting post 11 is disengaged from the clearance hole 81, thus releasing the restriction of the positioning component, thereby forming a simple and effective positioning lock structure.

[0034] The handrail 4 and the step 2 are fixed together by positioning components, which increases the stability of the handrail 4 and enhances the safety of the staff. At the same time, it is easy to adjust the relative position between the handrail 4 and the step 2, reduce space occupation, and improve the safety of the step 2. Example 3

[0035] This embodiment uses a pull-out boarding ladder for the bulletproof shielded container, such as... Figure 1 As shown, the device includes a guide rail 1 and a step 2 that slides along the guide rail 1. The two side walls of the step 2 in the width direction slide on the guide rail 1 via sliders, thereby adjusting the relative position of the step 2 on the guide rail 1. The bottom of the guide rail 1 is provided with a groove 3 that is recessed into the bottom of the cabin. The groove 3 is used to accommodate the step 2. After the step 2 is flipped on the guide rail 1, it is folded into the groove 3 to reduce the longitudinal space occupied by the step 2.

[0036] Combination Figure 5 and Figure 6 The step 2 has a support leg 17 that moves relative to the step 2 on the end side wall. The inner side wall of the step 2 has a sliding groove 16. The support leg 17 is connected to the sliding groove 16 through a sliding plate 14. The support leg 17 has an L-shaped structure. The middle part of the support leg 17 is hinged to one end of the sliding plate 14. A connecting rod 15 is hinged to the short side of the support leg 17. The end of the connecting rod 15 away from the support leg 17 is hinged to the other end of the sliding plate 14 through a short rod 21.

[0037] The top of the inner side of the slide plate 14 is connected to a guide rod 18 via an ear seat 22. A guide rod 29 is connected to the connecting end of the connecting rod 15 and the short rod 21. The guide rod 18 and the guide rod 29 are connected by a spring sleeve 20.

[0038] Under the action of external force, the slide plate 14 is pulled out along the slide groove 16 on the inner side wall of the step 2 until the free end of the support leg 17 is separated from the slide groove 16. As the support leg 17 falls, the change in its rotation angle causes the connecting rod 15 to rotate around the connection between the support leg 17 and the slide plate 14. After the support leg 17 has completely fallen, the connecting rod 15 causes the short rod 21 to rotate and separate from the slide groove 16. At this time, the first guide rod 18 and the second guide rod 19 are in the farthest state. When it is necessary to retract the support leg 17, the slide plate 14 is pushed into the slide groove 16 by external force. Under the action of external force, the support leg 17 moves towards the back of the slide plate 14 until the short rod 21 is lifted to the bottom of the slide groove 16. At this time, the first guide rod 18 and the second guide rod 19 are in the closest state, completing the retraction and fixation of the support leg 17.

[0039] Both sides of the step ladder 2 are equipped with support legs 17 in the width direction. The support legs 17 can adopt a telescopic rod structure, and their length can be designed to be adjustable. This allows the left and right steps of the step ladder 2 to support the ground simultaneously when the ground height is inconsistent. This solves the problem of step ladder angle changes caused by changes in the height of the cabin. The operation is simple, and it is easy to disassemble, assemble, and fold, increasing the support stability of the step ladder 2.

[0040] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
