[0002] A telescopic ladder is a ladder that can be stretched and shortened like a fishing rod. It is divided into two types: an engineering telescopic ladder and a bamboo telescopic ladder. It is very convenient to carry and store, and can be placed in a home closet, study, under the bed or in the trunk of a car. A vehicle-mounted telescopic ladder, as the name suggests, is a telescopic ladder designed for a carriage or roof. Generally, larger station wagons will be equipped with a telescopic ladder on the top to facilitate climbing to the roof. In order to facilitate the operation of the telescopic ladder, an electric telescopic ladder drive method is adopted. The hydraulic drive makes the ladder installed on the top tilt downward, so that the ladder originally retracted at the top of the vehicle can be fully unfolded.

[0033] See also Figure 1-9, including: a telescopic ladder reinforcement frame 1, a telescopic ladder pedal 3 installed on the inner side of the telescopic ladder reinforcement frame 1, a positioning pin 2 passing through the surface of the telescopic ladder reinforcement frame 1 and connected to the side of the telescopic ladder pedal 3, a pushing link 5 connected to the upper and lower groups of telescopic ladder pedals 3, a pushing link 5 connected to the pedal connector 6, and a hydraulic push rod 4 for pushing the pushing link 5 to move; when in use, the telescopic ladder reinforcement frame 1 is assembled at a suitable position on the roof of the station wagon. In the retracted state, multiple groups of telescopic ladder pedals 3 are connected by the pedal connector 6 and folded under the telescopic ladder reinforcement frame 1. The inner wall of the telescopic ladder reinforcement frame 1 is fixed with a push rod base 8 rotatably connected to the base of the hydraulic push rod 4. When unfolding, the pushing link 5 is pushed by the hydraulic push rod 4, so that the pushing link 5 pushes the pedal connector 6, and then the multiple groups of telescopic ladder pedals 3 in the folded state are unfolded obliquely downward. The above is a prior art structure, and the relevant principles are not repeated. It also includes:

[0034] The pedal slot 7 is provided at the top of the telescopic ladder pedal 3, and a support inner plate 10 is installed in the slot of the pedal slot 7. A groove is provided in the support inner plate 10 from top to bottom, and a solar panel 9 is installed in the groove of the support inner plate 10. The assembled support inner plate 10 and the solar panel 9 are placed at the outer side of the telescopic ladder pedal 3. Therefore, when the telescopic ladder pedal 3 is unfolded, the support inner plate 10 and the solar panel 9 are exposed, and the solar panel 9 is used to absorb solar energy. The unfolded solar panel 9 has a larger area, which saves energy and reduces emissions.

[0035] The positioning extension plate 26 is fixedly arranged at the front end of the telescopic ladder pedal 3, and an angle positioning hole 27 is opened on the surface of the positioning extension plate 26. The front end of the supporting inner plate 10 is fixedly provided with an angle positioning rod 11 plugged and connected with the angle positioning hole 27, wherein two groups of positioning extension plates 26 are arranged, respectively at the two front ends of the telescopic ladder pedal 3 and extending to the center of the telescopic ladder pedal 3, and the supporting inner plate 10 can be assembled on the inner side of the telescopic ladder pedal 3 through the plugging of the angle positioning hole 27 and the angle positioning rod 11, and the supporting inner plate 10 can be in the inner side of the telescopic ladder pedal 3. The angle positioning rod 11 and the angle positioning hole 27 are in the shape of a multi-faceted hole, and the groove shape of the angle positioning rod 11 and the angle positioning hole 27 are the same. Therefore, when the angle positioning rod 11 is plugged into the angle positioning hole 27 at different angles, the entire support inner plate 10 and the telescopic ladder pedal 3 will present different angles, so that the solar panel 9 installed on the surface of the support inner plate 10 can be oriented at different angles. When necessary, the solar panel 9 can be oriented to the sun as much as possible to maximize the use of solar energy.

[0036] The upper wall of the supporting inner plate 10 is provided with an embedded side groove 12 and an embedded main groove 13, and the surfaces of the embedded side groove 12 and the embedded main groove 13 are overlapped with the supporting side plate 14 and the supporting shaft plate 15. A positioning sleeve 16 is fixedly provided at the front end of the intersection of the supporting side plate 14 and the supporting shaft plate 15, and an embedded socket 17 is provided in the positioning sleeve 16. An embedded cylinder 18 is installed in the cylinder of the positioning sleeve 16, and a zoom cylinder 19 is fixedly provided at the bottom of the embedded cylinder 18. A limit hook 21 is fixedly provided at the bottom of the zoom cylinder 19, wherein the limit hook 21 adopts an L-shaped structure, and a limit socket 23 adapted to the limit hook 21 is provided at the top of the supporting inner plate 10, so that the limit hook 2 1 can be inserted into the limiting socket 23 longitudinally, and a limiting slot 24 is provided below the limiting socket 23, wherein the limiting slot 24 is connected to the limiting socket 23, and the limiting slot 24 is in the shape of a circular slot. After the limiting hook 21 enters the limiting slot 24 from the limiting socket 23, the limiting hook 21 can be rotated at an angle by rotating the embedded cylinder 18, so that the limiting hook 21 enters the limiting slot 24, so that the limiting hook 21 cannot longitudinally escape from the limiting slot 24, thereby completing the locking of the position of the embedded cylinder 18. The upper part of the supporting inner plate 10 is provided with a limiting socket 23 and a limiting slot 24 adapted to the limiting hook 21. The inner wall of the positioning sleeve 16 is provided with a limiting ring groove 25, and the limiting ring portion 22 is rotatably connected in the groove of the limiting ring groove 25. The lower edge of the embedded cylinder 18 is fixed with multiple groups of shock-absorbing spring assemblies 20 distributed in an annular array. The bottom of the shock-absorbing spring assembly 20 is fixed to the top of the limiting ring 22. When the supporting side plate 14 and the supporting shaft plate 15 need to be assembled, the limiting hook 21 is rotated and inserted into the limiting slot 24 to complete the support side plate 14 being clamped in the embedded side slot 12. At the same time, the supporting shaft plate 15 is clamped in the slot embedded in the main slot 13.

An operating top hole 28 is opened at the top of the tube 18, and the top of the embedded tube 18 is retracted into the opening of the positioning sleeve 16. When the support side plate 14 needs to be removed to reduce shadow obstruction, a tool or a finger is inserted into the operating top hole 28 to twist the embedded tube 18, so that the zoom tube 19 and the limit hook 21 rotate synchronously, and the limit hook 21 enters the limit plug 23, and the shock-absorbing spring assembly 20 in the compressed state will lift the embedded tube 18 upward, so that the support side plate 14 and the support shaft plate 15 can be peeled off upward. The support side plates 14 are oppositely distributed to form a V-shaped structure, and the intersection of the V-shaped structure is fixedly connected to the support shaft plate 15, so that the connection between the support side plates 14 and the support shaft plate 15 is more stable.
