[0027] Embodiment 1

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 as well as Figure 7 As shown, the embodiment provides an easily adjustable production line guardrail, which includes an outer shell 1, a mounting shaft 3, a cloth 4, a long rod 5, a side shell 6, an automatic dripping mechanism and a plurality of suction cups 2.

[0029] The side of the outer shell 1 has a through hole 101; the main body of the mounting shaft 3 is rotatably mounted on the inner side of the outer shell 1 and the upper end extends to the top of the outer shell 1 and is connected to a driving member, and one end of the cloth 4 is wound around the mounting shaft 3.

[0030] The outer end of the cloth 4 is connected to the long rod 5 through the through hole 101, the side shell body 6 is arranged on the side of the outer shell body 1, the inner side of the side shell body 6 is matched with the long rod 5, and the long rod 5 and the side shell body 6 have a detachable connection structure, and a movable rod 17 is vertically slidably installed on the inner side of the side shell body 6, and an elastic reset component is installed on the movable rod 17. The elastic reset component includes a slide bar 21 and a spring b22. The slide bar 21 is vertically arranged on the inner side of the side shell body 6, and the movable rod 17 is slidably installed on the slide bar 21. Two springs b22 are provided and are respectively mounted on the upper and lower ends of the slide bar 21. A plurality of L-shaped limit blocks 18 are connected side by side on the movable rod 17, and a plurality of connecting blocks 20 corresponding to the plurality of L-shaped limit blocks 18 are connected side by side on the long rod 5, and a wedge block 19 is connected to the outer end of the connecting block 20.

[0031] A plurality of suction cups 2 are installed at the bottom end of the outer shell 1; the automatic dripping mechanism is used to drip water into the inner sides of the plurality of suction cups 2, the automatic dripping mechanism comprises a water storage box 7 and a plurality of telescopic tube assemblies, the water storage box 7 is arranged at the inner bottom end of the outer shell 1, the plurality of telescopic tube assemblies correspond one to one with the plurality of suction cups 2, the telescopic tube assemblies comprise a movable tube 12, a fixed tube 13, a spring a14 and a limiting ring 15, the fixed tube 13 is vertically connected to the bottom end of the water storage box 7, the movable tube 12 movably passes through the suction cup 2 and the bottom end of the outer shell 1, the bottom end of the fixed tube 13 is arranged on the inner side of the movable tube 12, and the fixed tube 13 and the movable tube 12 are clearance-matched, a water flow hole 131 is provided at the bottom end of the fixed tube 13, an annular groove 121 is provided at the upper part of the movable tube 12, and a limiting ring 15 is arranged on the movable tube 12; a sealing ring 16 is provided at the upper end of the suction cup 2, and the movable tube 12 movably passes through the sealing ring 16.

[0032] When fencing the area within the production line, multiple outer shells 1 are equidistantly arranged in the area outside the production line, and the outer shell 1 is placed on the ground so that the suction cup 2 contacts the ground. At this time, the movable tube 12 begins to contact the ground, forcing the movable tube 12 to move upward. When the annular groove 121 moves to the position of the water flow hole 131, the water inside the water storage box 7 flows into the inner side of the movable tube 12 through the fixed tube 13, and then flows into the inside of the suction cup 2. Then the operator presses the outer shell 1 downward again, and drips water to the inner side of the suction cup 2, which can help improve the sealing between the suction cup 2 and the ground, so that the suction cup 2 is firmly adsorbed on the ground. When the annular groove 121 moves to the upper position of the water flow hole 131, the movable tube 12 blocks the water flow hole 131, and the water no longer continues to flow out. Then, the long rod 5 is pulled outward to unwind the cloth 4. When the long rod 5 moves close to the position of the adjacent outer shell 1, the long rod 5 is inserted into the inner side of the side shell 6. At this time, the inclined surface of the wedge block 19 squeezes the L-shaped limit block 18 to move upward. When the long rod 5 moves to the limited position, the end of the L-shaped limit block 18 passes over the wedge block 19, and the L-shaped limit block 18 is reset downward under the elastic force of the spring b22, thereby realizing the fixed connection between the side shell 6 and the long rod 5. In summary, the technical scheme can achieve effective fixation of the device by arranging multiple suction cups 2, and can automatically drip water into the suction cup when the suction cup is installed to ensure its sealing by arranging an automatic dripping mechanism. By arranging a retractable cloth 4, the enclosure range of the device is adjustable, and it is easy to store and occupies little space.

[0033] Embodiment 2

[0034] like Figure 5As shown, the present embodiment proposes a production line guardrail that is easy to adjust. Compared with the first embodiment, in the present embodiment, the driving member includes a sleeve 8 and a crank 10. The sleeve 8 is vertically slidably installed on the top of the mounting shaft 3. The crank 10 is connected to the sleeve 8. A gear ring 9 is installed on the sleeve 8. A circular ring 11 is provided on the top of the outer shell 1. A tooth groove 111 that matches the gear ring 9 is opened on the circular ring 11. When unwinding the cloth 4, the sleeve 8 is pulled upward to drive the gear ring 9 to move out from the inner side of the tooth groove 111, and then the mounting shaft 3 can be driven to rotate to realize the unwinding of the cloth 4. After the unwinding work is completed, due to the action of gravity, the gear ring 9 falls into the inner side of the tooth groove 111, thereby realizing the limitation of the extended length of the cloth 4.

[0035] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
