[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings, wherein the same components are indicated by the same reference numerals.

[0022] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0023] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0024] Embodiment 1

[0025] Combined with Figure 1 and Figure 2 As shown, an inclined ladder structure convenient for use in a carriage comprises a base 1, on which fixed seats 2 are symmetrically arranged, a ladder frame 3 is rotatably arranged between the two fixed seats 2, a plurality of support tubes 4 are fixedly arranged on the ladder frame 3, and a fixing assembly is hingedly arranged at one end of the ladder frame 3 away from the base 1, the fixing assembly comprises a fixing piece 5 rotatably arranged on one side of the ladder frame 3, a screw hole 6 is arranged on the upper surface of the fixing piece 5, a screw rod 7 is threadedly inserted in the inner thread of the screw hole 6, a fixing plate 8 is arranged at one end of the screw rod 7, and the fixing plate 8 is rotatably connected to the screw rod 7.

[0026] Through the above structure, the fixing member 5 is clamped on the edge of the carriage, and the screw rod 7 is rotated so that the fixing member 5 fixes and clamps the carriage, thereby fixing the ladder frame 3. At the same time, the base 1 increases the ground contact area of ​​the device and improves the stability of the device.

[0027] Combined with Figure 1 and Figure 5 As shown, the support tube 4 is provided with a plurality of anti-skid sleeves 9, the anti-skid sleeves 9 are made of rubber, and the surface of the anti-skid sleeves 9 is a wavy structure, a slide groove 13 is provided on one side of the fixing member 5, a slider 14 adapted to the slide groove 13 is provided on one side of the fixing plate 8, the slider 14 slides in the slide groove 13, an anti-skid pad 16 is provided on the contact surface between the fixing plate 8 and the carriage, and a handrail 15 is provided on the ladder frame 3.

[0028] Through the above structure, the wavy surface and the anti-slip sleeve 9 made of rubber material improve the protection performance of the support tube 4, avoiding slipping when people step on it. The cooperation between the slider 14 and the slide groove 13 limits the movement trajectory of the fixed plate 8, avoiding the fixed plate 8 from rotating with the screw rod 7. The setting of the handrail 15 plays a certain protective role, and people can climb with the help of it.

[0029] Embodiment 2

[0030] Based on the first embodiment, combined with the attached Figure 3 and Figure 4As shown, a fixing frame 10 is provided on the fixing seat 2, and a plurality of positioning holes 11 are provided on the fixing frame 10. A positioning hole 2 12 is provided on the ladder frame 3. An insertion rod 17 is inserted into the positioning hole 11, and the insertion rod 17 passes through the positioning hole 2 12.

[0032] The specific usage is as follows:

[0033] According to the specific situation of the carriage, the fixing assembly is selectively used. If the carriage has a pedal for the fixing assembly to clamp, the ladder frame 3 is rotated to a suitable angle, and the fixing frame 10 is clamped at the exit pedal of the carriage. The screw rod 7 is rotated to drive the fixing plate 8 to descend, so that the fixing plate 8 is close to the carriage to achieve a fixed connection between the ladder frame 3 and the carriage. The anti-slip pad 16 increases the friction force, making the fixing clamping more stable. Then, the insertion rod 17 is inserted into the positioning hole 11 at the corresponding position. The insertion rod 17 passes through the positioning hole 11 on one side and penetrates the positioning hole 12, and then passes out from the positioning hole 11 on the other side to fix the angle of the ladder frame 3;

[0034] The user can climb with the help of the handrails 15 on both sides, and the anti-slip sleeves 9 can increase the friction force and reduce the probability of the user falling due to slipping.

[0035] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
