Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-7 In this embodiment of the invention, a steel ladder structure for a camping shelter includes a camping shelter body 1 and a steel ladder 2. The steel ladder 2 is a telescopic structure, rotatably connected to one side of the camping shelter body 1 via a rotating connecting mechanism 3. Locking mechanisms 4 are provided on both sides of the steel ladder 2, which can lock the retracted steel ladder 2. When in use, the steel ladder 2 is lowered; when not in use, the steel ladder 2 is rotated to an upright position and fixed to one side of the camping shelter body 1 via the locking mechanisms 4.

[0023] The steel ladder 2 consists of a fixed ladder section 21 and a movable ladder section 22. The movable ladder section 22 is slidably connected to the fixed ladder section 21. The length of the steel ladder 2 can be adjusted by adjusting the length of the movable ladder section 22 extending out of the fixed ladder section 21. The movable ladder section 22 can be retracted for storage, further reducing the space occupied.

[0024] The fixed stair section 21 includes two oppositely arranged fixed side plates 211 and a plurality of first step pedals 212 fixedly connected between the two fixed side plates 211. The plurality of first step pedals 212 are equidistantly arranged. Dovetail-shaped guide grooves 213 are opened oppositely on the two side walls of the fixed side plates 211. A plurality of connecting holes 214 are opened equidistantly along the length direction on the top surface of the fixed side plates 211. A baffle 215 is fixedly connected to the end of the top surface of the fixed side plates 211.

[0025] The movable ladder section 22 includes two U-shaped plates 221 arranged opposite each other and multiple second foot pedals 222 fixedly connected between the two U-shaped plates 221 at equal intervals. The inner sides of the two side walls of the U-shaped plates 221 are fixedly connected to guide rails 223. The guide rails 223 are adapted to the shape of the guide grooves 213 and are slidably connected to the guide grooves 213. Limiting plates 224 are fixedly connected to the front and rear sides of the top wall of the U-shaped plates 221 respectively. The limiting plates 224 are used in conjunction with the baffles 215 to prevent the movable ladder section 22 from sliding out of the fixed ladder section 21. The top wall of the U-shaped plates 221 has mounting holes 225, and bolts 226 are installed in the mounting holes 225. After the movable ladder section 22 is adjusted to the correct length in the fixed ladder section 21, the rotating bolts 226 can be threaded into the corresponding connecting holes 214 to keep the movable ladder section 22 and the fixed ladder section 21 stable.

[0026] The rotating connection mechanism 3 includes a fixed seat 31 and a rotating shaft 32. There are two fixed seats 31, which are fixedly connected to the side of the camping house body 1. The rotating shaft 32 is rotatably connected to the opposite side of the two fixed seats 31 through bearings. The other end of the rotating shaft 32 is fixedly connected to the fixed ladder section 21 of the steel ladder 2, so that the steel ladder 2 can rotate around the rotating shaft 32.

[0027] The locking mechanism 4 includes a locking component and a locking hole 41. The locking hole 41 is located on the outside of the two fixed side plates 211. The locking component includes a mounting box 42, which is fixedly connected to the fixed base 31. The mounting box 42 has a horizontally penetrating mounting groove 43. A connecting rod 44 is movably connected to the outer side of the mounting groove 43. A pull plate 45 is fixedly connected to the outer side of the connecting rod 44. A limit block 46 is fixedly connected to the other end of the connecting rod 44. A spring 47 is sleeved on the connecting rod 44. A locking rod 48 is fixedly connected to the other side of the limit block 46. The locking rod 48 can be inserted into the locking hole 41. When the steel ladder 2 needs to be retracted, the movable ladder section 22 is retracted and fixed with bolts 226. Then, the steel ladder 2 is rotated to a vertical position, and the locking rod 48 is inserted into the locking hole 41 to fix the steel ladder 2. If the steel ladder 2 needs to be lowered for use, the pull plate 45 is pulled outward. The pull plate 45 drives the connecting rod 44 and the locking rod 48 to move, so that the locking rod 48 releases the steel ladder 2 from the fixation.

[0028] To enhance the stability of the steel ladder 2, a support mechanism 5 is installed on the fixed ladder section 21, providing additional support for the steel ladder 2. The support mechanism 5 includes a hinge seat 51, an adjusting screw 52, ​​a support leg 53, a locking nut 54, and a rubber pad 55. The hinge seat 51 is fixedly connected to the end of the fixed ladder section 21. The adjusting screw 52 is rotatably connected to the hinge seat 51. The upper end of the adjusting screw 52 is a smooth annular connecting part, and the lower end has an external thread. The lower end of the adjusting screw 52 is threadedly connected to the support leg 53. The bottom of the support leg 53 is fixedly connected to the rubber pad 55, and the locking nut 54 is located on the adjusting screw 52 at the top of the support leg 53. When using the support mechanism 5, the operator rotates the support leg 53. Since the adjusting screw 52 is fixed, the rotation of the support leg 53 is converted into linear motion along the adjusting screw 52, ​​thereby adjusting the height of the support mechanism 5. After adjusting the height, the locking nut 54 is tightened to prevent loosening during use.

[0029] The working principle of this utility model is as follows: When the steel ladder needs to be unfolded, first pull the pull plate 45 of the locking mechanism 4 outward, which drives the connecting rod 44 and the locking rod 48 to move towards the mounting box 42. The spring 47 is compressed, causing the locking rod 48 to disengage from the locking hole 41, releasing the upright locking state of the steel ladder 2. Then it can rotate downward around the rotating shaft 32. If it is necessary to adjust the length of the steel ladder 2, pull the movable ladder section 22 outward, so that the guide rail 223 of the U-shaped plate 221 slides along the dovetail guide groove 213 of the fixed side plate 211 until the extension length of the movable ladder section 22 meets the usage requirements. Then use the bolt 226 to lock the movable ladder section 22 with the fixed ladder section 21. Then lower the support mechanism 5 and adjust the height by rotating the support leg 53 so that the rubber pad 55 contacts the ground and provides support force. Tighten the locking nut 54 to prevent loosening during use.

[0030] When the steel ladder 2 needs to be retracted, first retract the movable ladder section 22, loosen the bolt 226, and push the movable ladder section 22 inward so that it slides into the fixed ladder section 21 along the guide groove 213 until the limit plate 224 abuts against the baffle 215. Then tighten the bolt 226 again to fix the retracted state of the movable ladder section 22. Then lift the end of the steel ladder 2 and rotate it upward around the rotating shaft 32 until the steel ladder 2 is upright. During the process of the steel ladder 2 rotating to the upright state, pull the pull plate 45 outward to drive the locking rod 48 to move to both sides to avoid interfering with the rotation of the steel ladder 2. After the steel ladder 2 moves into place, release the pull plate 45, the spring 47 returns to its original position and pushes the locking rod 48 to move the steel ladder 2 so that it inserts into the locking hole 41 on the outside of the fixed side plate 211, fixing the steel ladder 2 to the camping house body 1, completing the storage and locking.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
