[0003] In order to overcome at least one of the above-mentioned defects of the prior art, the present invention provides a movable vehicle-mounted storage ladder to solve the problem that the vehicle carrier cannot be moved.

[0004] The technical solution adopted by the present invention to solve the problem is:

[0005] A movable vehicle-mounted storage ladder comprises a vehicle bucket, a U-shaped frame group is slidably connected to the vehicle bucket, a positioning mechanism for fixing the U-shaped frame group is provided on the U-shaped frame group, a slider is slidably connected to the U-shaped frame group, a first ladder is rotatably connected to the slider, a second ladder is slidably connected to the first ladder, a fixing mechanism for locking the first ladder and the second ladder is provided on the second ladder, a hook is provided on the first ladder, and a groove matching the hook is provided on the U-shaped frame group.

[0006] Through the above scheme, the U-shaped frame group can be moved by the sliding connection, and the U-shaped frame group can be fixed on the truck bed through the positioning mechanism. The first ladder is slidably connected to the U-shaped frame group through the slider, and the ladder can be easily taken out of or put into the truck bed without the need for complicated disassembly or assembly processes. The ladder can be compactly stored in the truck bed, saving storage space. The cooperation of the hook and the groove provides an additional support point for the ladder, thereby increasing stability.

[0007] Furthermore, the U-shaped frame group includes a first U-shaped frame and a second U-shaped frame, at least one first slide groove is provided on both sides of one side of the truck bed, and first slides slidably connected to the first slide groove are provided on opposite sides of the first U-shaped frame and the second U-shaped frame, the number of the first slides is the same as the number of the first slide grooves, the first slide on the first U-shaped frame is connected to the first slide on the second U-shaped frame through a slide rod, and a positioning mechanism is provided on one of the slide rods.

[0008] Through the above-mentioned further scheme, by arranging at least one first slide groove on both sides of one side of the truck bed, and providing first slides slidably connected to the first slide groove on the opposite sides of the first U-shaped frame and the second U-shaped frame, it is ensured that the U-shaped frame group can move smoothly along the slide groove, reducing shaking during transportation. Since the first slide on the first U-shaped frame is connected to the first slide on the second U-shaped frame by a slide rod, this ensures that the first U-shaped frame and the second U-shaped frame can move synchronously during operation. A positioning mechanism is provided on one of the slide rods, which can fix the first U-shaped frame and the second U-shaped frame in a specific position when needed to prevent them from accidentally sliding during vehicle driving, thereby ensuring the safety of transportation.

[0009] Furthermore, a plurality of positioning holes are provided in the first slide groove that is slidably connected to the slide rod provided with a positioning mechanism. The positioning mechanism includes a first spring, a positioning box and a positioning rod. The slide rod is provided with a sliding hole, and a positioning box is provided on the slide rod at the sliding hole. The positioning rod is slidably connected in the positioning box.

A limit plate is provided in the middle of the positioning rod. The first spring is provided in the positioning box and is sleeved on the positioning rod. One end of the first spring is against the limit plate, and the other end is against the top inside the positioning box.

[0010] Through the above-mentioned further scheme, by setting a number of positioning holes in the first slide groove, cooperating with the first spring, positioning box and positioning rod on the slide rod, the first U-shaped frame and the second U-shaped frame can be accurately fixed at different positions. A handle is provided at one end of the positioning rod, so that the user can lock or unlock the slide rod through simple manual operation. When the position needs to be adjusted, it is only necessary to pull the handle to disengage the positioning rod from the positioning hole, and the first U-shaped frame and the second U-shaped frame can be moved freely. After reaching the desired position, release the handle, and under the action of the first spring, the positioning rod will automatically embed into the corresponding positioning hole to complete the locking.

[0011] Furthermore, U-shaped slide rails are provided on both side surfaces of the first U-shaped frame and the second U-shaped frame, and a pulley is provided at one end of the slider for sliding connection with the U-shaped slide rail, and the pulley is embedded in the slide rail.

[0012] Through the above further solution, by arranging U-shaped slide rails on both sides of the first U-shaped frame and the second U-shaped frame, and installing a matching pulley at one end of the slider, it is ensured that the slider can slide up and down smoothly along the slide rails, and the pulley is embedded in the slide rails, reducing friction resistance, making the ladder deployment and folding process easier and more comfortable.

[0013] Furthermore, the slider is provided with a pulley that is rotatably connected to the lower end of the first ladder at one end, the first ladder is provided with multiple second slide grooves, and L-shaped limit plates are provided on both sides of the upper end of the second ladder.

[0014] Through the above-mentioned further scheme, the slider is provided with one end of the pulley rotatably connected to the lower end of the first ladder, so that the first ladder can rotate freely relative to the slider, which not only increases the adaptability of the ladder in different application scenarios, but also can adjust the angle of the ladder according to actual needs, thereby improving the flexibility of use. A plurality of second slide grooves are provided on the first ladder, and the corresponding L-shaped limit plate on the second ladder is provided with a second slide on both sides. This design ensures that the second ladder can slide smoothly on the first ladder, and provides additional lateral support through the L-shaped limit plate to prevent the ladder from tipping over or derailing during use, thereby enhancing the safety and stability of the overall structure. Since the second ladder is slidably connected to the second slide groove on the first ladder through the second slide, the height of the second ladder can be easily adjusted according to specific needs to adapt to different working height requirements.

[0015] Furthermore, the fixing mechanism includes a mounting platform, a second spring, a fixing hook and a fixing buckle. The bottom end of the second ladder is provided with a fixing platform, the upper end of the fixing platform is against the bottom end of the first ladder, the fixing platform is flush with the side of the first ladder facing the truck bucket, the fixing platform is fixedly installed on the side of the fixing platform facing the truck bucket, the fixing hook is fixedly installed on the lower end of the first ladder facing the truck bucket, the middle part of the fixing buckle is rotatably connected to the mounting platform, one end of the fixing buckle is connected to the fixing hook buckle, and the other end is provided with a buckle handle, one end of the second spring is fixedly connected to the mounting platform, and the other end is fixedly connected to one end of the fixing buckle provided with a buckle handle.

[0016] Through the above-mentioned further scheme, by arranging a fixed platform at the bottom end of the second ladder and making its upper end counterbalance the bottom end of the first ladder, it is ensured that the two parts of the ladder can fit tightly when connected. The design of the fixed platform facing the truck bed side and being flush with the first ladder facing the truck bed side ensures the consistency of the overall appearance of the ladder and the symmetry of the structure, thereby improving the stability and safety of the connection. The combination of the fixing hook and the fixing buckle provides a simple and effective locking method. It only needs to connect one end of the fixing buckle with the fixing hook buckle to achieve quick locking. The other end is provided with a buckle handle for convenient manual unlocking, which not only simplifies the operating steps, but also reduces the inconvenience caused by complex locks. The second spring enables the fixing buckle to have the function of automatic reset. When the buckle handle is pressed to unlock, the fixing buckle will automatically return to its initial position under the action of the second spring, ready for the next locking, which not only improves the convenience of use, but also avoids the safety hazards caused by forgetting to reset.

[0017] Furthermore, the first ladder is provided with hooks on the upper end facing the truck bed and corresponding to the first U-shaped frame and the second U-shaped frame, and the first U-shaped frame and the second U-shaped frame are provided with grooves matching the hooks on the outer side.

[0018] Through the above-mentioned further solution, by arranging a hook at the upper end of the first ladder facing the truck bed, and arranging matching grooves on the outer sides of the first U-shaped frame and the second U-shaped frame, it is ensured that the ladder can be firmly fixed to the U-shaped frame assembly when unfolded or stored. The coordinated use of the hook and the groove can quickly and easily complete the fixing or releasing operation of the ladder without the need for complicated tools or steps. The lock can be achieved by simply aligning the hook with the groove and inserting it. Conversely, it can be easily pulled out and unlocked, which greatly improves the convenience of use.

[0019] Furthermore, a trough body is provided at the upper end of the first ladder, and a plurality of bosses which are engaged with the trough body are provided on the bottom of the vehicle bucket.
