The climber locking device provided by the utility model is provided with a ratchet and fits it with the guide tube. When the pawl is clamped on the ratchet, the ratchet self-locks, thereby locking the relative position of the climber relative to the guide tube; when the pawl is detached from the ratchet, the ratchet self-locks, thereby achieving the purpose of moving the climber relative to the guide tube. In this way, by locking the position of the climber relative to the guide tube, the film can be prevented from being pulled and deformed, the service life of the film can be extended, and the use and maintenance costs of the film can be reduced.

[0004] However, in the above technical solution, the ratchet is self-locked only by energizing the electromagnet to control the claw to be stuck on the ratchet, thereby locking the position of the climber on the guide tube. However, this patent relies on the mutual contact between the ratchet and the climbing rod to lock the climber. The contact area between the ratchet teeth on the ratchet and the climbing rod is limited. If there are no ratchets on the climbing rod, the self-locking effect between the climbing rod and the ratchet is limited. Utility Model Content

[0025] In an optional embodiment, the roller 4 is provided with a plurality of receiving grooves distributed around the central axis of the roller 4, and each receiving groove is connected to an anti-slip block 5; the anti-slip block 5 is made of, but not limited to, rubber material, and has anti-slip grooves.

[0026] The self-locking component is connected to the climber body 1; in the initial state of the self-locking component, the self-locking end of the self-locking component moves toward the central axis of the climbing tube 2, limiting the movement of the climber body 1 along the central axis of the climbing tube 2;

[0027] The self-locking assembly includes a support frame 6, a fixed plate 7, a guide rod 8, a movable plate 9, a limit block 10, an elastic member 12 and a telescopic member 13. Two support frames 6 are symmetrically arranged, and the support frame 6 is detachably connected to the climber body 1; the support frame 6 is connected to the gap between adjacent connecting pieces 3, and the cross-sectional shape of the support frame 6 is U-shaped; the number of fixed plates 7 corresponds to that of the support frame 6, the fixed plate 7 is connected to the support frame 6, the guide rod 8 is connected to the fixed plate 7, and one end of the guide rod 8 is connected to the movable plate 9, which fits the shape of the outer wall of the climbing tube 2, and the other end of the guide rod 8 passes through the fixed plate 7 and the support frame 6. There are multiple limit blocks 10, which are connected to the movable plate 9. The limit rod cooperates with the limit groove 11 provided on the climbing tube 2. The matching groove 11 is provided at the designated position of the climbing tube 2, such as the highest point, the lowest point and the middle position. The self-locking of the remaining positions depends on the friction between the limit block 10 itself and the climbing tube 2. The number of elastic members 12 corresponds to that of the guide rod 8. The elastic member 12 is selected from but not limited to a spring. The elastic member 12 is sleeved on the outside of the guide rod 8, and the two ends of the elastic member 12 are respectively connected to the fixed plate 7 and the movable plate 9. The telescopic member 13 is provided between the fixed plate 7 and the movable plate 9.

[0028] The telescopic part 13 is composed of an electromagnet 16 and a magnetic part 17. The electromagnet 16 is sleeved on the outside of the guide rod 8, the electromagnet 16 is connected to the fixed plate 7, and the magnetic part 17 is connected to the movable plate 9. The shape of the magnetic part 17 fits the electromagnet 16, and the magnetic part 17 is magnetically connected to the electromagnet 16.

[0029] Example 2

[0030] like Figure 2-Figure 5 As shown, the climber proposed by the present invention, compared with the first embodiment, the detailed structure of the self-locking component is recorded in this embodiment.

[0031] In an optional embodiment, the support frame 6 is connected to symmetrically arranged limit posts 14, and the limit posts 14 are slidably connected to the fixing grooves 15 provided on the connecting piece 3;

[0032] In an optional embodiment, a symmetrically arranged sealing plate 18 is detachably connected to the support frame 6; the sealing plate 18 seals the upper and lower ends of the support frame 6 to a certain extent, reducing the influence of external factors on the electromagnet;

[0034] In summary, when the present invention is used, the user controls the motor and the electric film roller through the control device to work, and the film is rolled up by rising or falling on the electric film roller. When the film is rolled up, the electric film roller will drive the climber body 1 to move along the central axis of the climbing tube 2, and the roller 4 on the climber body 1 rolls on the climbing tube 2. When the power is turned on, the circuit of the electromagnet 16 is also turned on synchronously, and the magnetic force of the electromagnet 16 attracts the magnetic element 17 to approach, and the magnetic element 17 drives the movable plate 9 and the guide rod 8 to move. The movable plate 9 cooperates with the fixed plate 7 to compress the length of the elastic element 12, and the upper limit block 10 of the movable plate 9 is moved from the current climbing The climbing tube 2 is moved out of the limit groove 11 on the climbing tube 2. When the climber body 1 moves to the predetermined position, the electric film roll device and the climber body 1 stop running and the power is cut off. At this time, the electromagnet 16 loses power and the magnetic force disappears. The magnetic attraction part 17 on the movable plate stops being magnetically attracted by the electromagnet 16. The elastic part 12 pushes the movable plate 9, the magnetic attraction part 17 and the limit column 14 away from the electromagnet 16 by its own elastic force. The movable plate 9 is close to the climbing tube 2. The limit block 10 on the movable plate 9 and the limit groove 11 opened on the climbing tube 2 are mutually engaged, which limits the position of the climber body 1 to prevent it from falling off along the climbing tube 2 and pulling the film due to its own weight.

[0035] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
