[0002] In industries such as power, communications, and construction, insulated ladders are important tools for ensuring safety when working at heights. Especially in high-voltage environments, the insulation performance of insulated ladders is directly related to the safety of operators. Traditional insulated ladders are mostly of fixed length, which makes it difficult to adapt to the working needs of different heights, and they are inconvenient to carry and store.

[0003] A Chinese patent discloses an insulated flat ladder (authorization announcement number CN203905791U). This patented technology enhances safety protection by setting an arc-shaped joint and a safety rope, effectively preventing the ladder from slipping and ensuring the safety of personnel working on live power transmission lines. It also has a simple structure, is easy to use, and has high safety performance.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: ladders of fixed length cannot adapt to working environments of different heights. For example, using an excessively long ladder in a low space will increase the difficulty of operation, while in a high space, if the ladder is not long enough, it will not be able to reach the working height. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing technology has the disadvantage of not being able to be adjusted according to actual work needs. To this end, we propose an adjustable insulated flat ladder.

[0007] Preferably, the size of the insert rod is adapted to the size of the slot, and the surface of the insert rod is inserted into the interior of the slot.

[0008] Preferably, both the main ladder and the auxiliary ladder are made of polyvinyl chloride.

[0009] Preferably, a storage spring is fixedly connected to the side of the push block near the control groove, and the side of the storage spring away from the control groove is fixedly connected to the push block.

[0010] Preferably, both ends of the control groove are provided with sliding grooves, and both ends of the push block are fixedly connected with sliders, the surface of the sliders being slidably connected to the inside of the sliding grooves.

[0011] Preferably, guide grooves are provided at both ends of the adjustment groove, and guide blocks are fixedly connected to both ends of the auxiliary ladder, with the surface of the guide block slidingly connected to the interior of the guide groove.

[0012] Preferably, a buffer spring is fixedly connected to the bottom of the adjustment groove, and a top plate is fixedly connected to the top of the buffer spring.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] In this invention, the operator pushes the push block into the control slot, causing the push block to move the insertion rod and simultaneously release the insertion rod from the slot. The operator then adjusts the length of the auxiliary ladder according to work requirements. After adjusting to the appropriate length, the insertion rod is reinserted into the slot to fix the position of the auxiliary ladder, thereby achieving the adjustment function.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] Reference Figure 1 - Figure 5As shown, this utility model provides a technical solution: an adjustable insulated flat ladder, including a main ladder 1, with adjustment grooves 2 on both sides inside the main ladder 1, a secondary ladder 3 slidably connected inside the adjustment grooves 2, adjustment boxes 4 fixedly connected to both ends of the main ladder 1, control grooves 5 on both ends of the adjustment boxes 4, push blocks 7 slidably connected inside the control grooves 5, a through groove 8 on the side of the control groove 5 near the secondary ladder 3, a plug rod 9 fixedly connected to the side of the push block 7 near the secondary ladder 3, a straight groove 10 on the side of the secondary ladder 3 near the adjustment box 4, and several slots 11 on both ends of the straight groove 10. When the operator pushes the push block 7 into the control groove 5, the push block 7 moves the plug rod 9, and simultaneously releases the plug rod 9 from the slot 11. The operator adjusts the length of the secondary ladder 3 according to the work requirements. After adjusting to the appropriate length, the plug rod 9 is reinserted into the slot 11 to fix the position of the secondary ladder 3, thereby achieving the adjustment function.

[0023] Reference Figure 2 and Figure 5 As shown in this embodiment: the size of the insertion rod 9 is adapted to the size of the slot 11, and the surface of the insertion rod 9 is inserted into the interior of the slot 11. By adapting the size of the insertion rod 9 to the size of the slot 11, the insertion rod 9 can be stably inserted into the interior of the slot 11, which effectively improves the overall connection strength and avoids safety hazards caused by unstable connection.

[0024] Reference Figure 1 As shown in this implementation scheme: both the main ladder 1 and the auxiliary ladder 3 are made of polyvinyl chloride. By making both the main ladder 1 and the auxiliary ladder 3 of polyvinyl chloride, the main ladder 1 and the auxiliary ladder 3 have insulating properties, which effectively prevents safety accidents caused by current flow during use and greatly improves the safety of use. At the same time, polyvinyl chloride material also has good corrosion resistance and weather resistance, which can resist the erosion of the ladder by various harsh environments and extend the service life of the ladder.

[0025] Reference Figure 5 As shown in this embodiment: a storage spring 12 is fixedly connected to the side of the push block 7 near the control groove 5, and the side of the storage spring 12 away from the control groove 5 is fixedly connected to the push block 7. When the operator pushes the push block 7 into the control groove 5, the push block 7 compresses the storage spring 12 to store force, and drives the insertion rod 9 to release the limit between it and the slot 11. After the operator adjusts the appropriate position of the auxiliary ladder 3, he aligns the insertion rod 9 with the slot 11 and releases the push block 7. Under the action of the rebound force of the storage spring 12, the push block 7 quickly resets, and drives the insertion rod 9 to be firmly inserted into the slot 11, thus realizing the quick and firm fixation of the position of the auxiliary ladder 3.

[0026] Reference Figure 5As shown in this embodiment: both ends of the control slot 5 are provided with sliding grooves 13, and both ends of the push block 7 are fixedly connected with sliders 14. The surface of the sliders 14 is slidably connected to the inside of the sliding grooves 13. When the operator moves the push block 7, the push block 7 drives the sliders 14 to slide inside the sliding grooves 13. Through the above settings, the movement of the push block 7 is more stable and smooth, effectively reducing the risk of equipment damage caused by improper operation. At the same time, the sliding connection design between the sliders 14 and the sliding grooves 13 enhances the flexibility and durability of the equipment, enabling the entire device to maintain a good working condition during use.

[0027] Reference Figure 3 As shown in this embodiment: guide grooves 15 are provided at both ends of the adjustment groove 2, and guide blocks 16 are fixedly connected to both ends of the auxiliary ladder 3. The surface of the guide block 16 is slidably connected to the inside of the guide groove 15. When the operator adjusts the position of the auxiliary ladder 3, the auxiliary ladder 3 drives the guide block 16 to slide inside the guide groove 15. Through the above settings, the position adjustment of the auxiliary ladder 3 is more flexible and convenient, improving the practicality of the device. At the same time, the guide block 16 can effectively reduce frictional resistance during the sliding process inside the guide groove 15, ensuring the smooth operation of the device. In addition, this design also enhances the connection stability between the auxiliary ladder 3 and the overall structure, making the device safer and more reliable during use.

[0028] Reference Figure 4 As shown in this embodiment: a buffer spring 6 is fixedly connected to the bottom of the adjusting groove 2, and a top plate 17 is fixedly connected to the top of the buffer spring 6. When the auxiliary ladder 3 moves downward under the action of external force, the top plate 17 will compress the buffer spring 6 accordingly. The elastic characteristics of the buffer spring 6 can effectively absorb and disperse the impact force, thereby slowing down the descent speed of the auxiliary ladder 3 and preventing damage to the equipment due to sudden impact.

[0029] Working principle: The operator pushes the push block 7 into the control slot 5, causing the push block 7 to move the insertion rod 9. Simultaneously, the insertion rod 9 releases its restraint from the slot 11. The operator adjusts the length of the auxiliary ladder 3 according to work requirements. After adjusting to the appropriate length, the insertion rod 9 is reinserted into the slot 11 to fix the position of the auxiliary ladder 3, thus achieving the adjustment function. The matching size of the insertion rod 9 with the slot 11 ensures that the insertion rod 9 can be securely inserted into the slot 11, effectively improving the overall connection strength and avoiding safety hazards caused by unstable connections. Both the main ladder 1 and the auxiliary ladder 3 are made of polyvinyl chloride. This design ensures insulation between the main ladder 1 and the auxiliary ladder 3, effectively preventing accidents caused by current flow during use and greatly improving safety. Furthermore, the PVC material offers excellent corrosion and weather resistance, resisting the erosion of the ladder in harsh environments and extending its lifespan. When the operator pushes the push block 7 into the control slot 5, the push block 7 compresses the storage spring 12, storing energy and causing the insertion rod 9 to release its restraint from the slot 11. After adjusting the auxiliary ladder 3 to the appropriate position, the operator aligns the insertion rod 9 with the slot 11 and releases the push block 7. Under the rebound force of the storage spring 12... Push block 7 quickly resets, causing insert rod 9 to be firmly inserted into slot 11, achieving rapid and secure fixation of the auxiliary ladder 3. When the operator moves push block 7, push block 7 drives slider 14 to slide inside slide groove 13. Through the above settings, the movement of push block 7 is more stable and smooth, effectively reducing the risk of equipment damage due to improper operation. At the same time, the sliding connection design between slider 14 and slide groove 13 enhances the flexibility and durability of the equipment, allowing the entire device to maintain a good working condition during use. When the operator adjusts the position of auxiliary ladder 3, auxiliary ladder 3 drives guide block 16 in guide groove. The sliding mechanism inside guide plate 15 allows for more flexible and convenient adjustment of the position of the auxiliary ladder 3, improving the practicality of the device. Simultaneously, the sliding of guide block 16 within guide groove 15 effectively reduces frictional resistance, ensuring smooth operation of the device. Furthermore, this design enhances the connection stability between the auxiliary ladder 3 and the overall structure, making the device safer and more reliable during use. When the auxiliary ladder 3 is subjected to external force and moves downwards, top plate 17 compresses buffer spring 6. The elastic properties of buffer spring 6 effectively absorb and disperse impact force, thereby slowing the descent speed of the auxiliary ladder 3 and preventing damage to the equipment due to sudden impact.
