Technical Field

[0001] The utility model relates to the technical field of warning equipment, in particular to a flattening and tightening device for a warning belt. Background Art

[0002] Warning tapes are increasingly used in production and life scenarios. For example, cloth-type warning tapes are often used in engineering construction or other areas that require warning, indication, and isolation. Warning tapes must be kept horizontal during application. They are an important part of the solemnity and cleanliness of the warning area and are related to the visual effect of the entire warning area.

[0003] For the warning tape used in fixed places, because it has the characteristic of fixed length, the warning tape can be fixed and connected with pillars during installation. Some pillars have automatic tightening springs to ensure that the warning tape is flat and beautiful.

[0004] However, in some specific places, temporary cordon tapes are set up. Due to the complex on-site environment, the length of the cordon tapes varies with the different fenced areas on site. The cordon tapes are often tied to fixed objects. At this time, it is difficult to ensure that the cordon tapes are flat and tightened. Summary of the Invention

[0007] Furthermore, the outer diameter of the screw above the hexagonal rhombus is smaller than the circumscribed circle thereof.

[0008] Furthermore, a nut is screwed onto the bottom end of the screw.

[0009] Furthermore, the device also includes a sealing plate, which penetrates into the bottom end of the screw and is arranged on the bottom surface of the chassis of the I-shaped handwheel and abuts against the one-way ratchet.

[0010] Since the utility model adopts the above-mentioned technical solution for the flat tightening device of the warning tape, that is, the device includes an I-shaped handwheel, a guide rod, a one-way ratchet and a screw, the chassis of the I-shaped handwheel is provided with an inverted T-shaped cavity upward, the screw is inserted into the one-way ratchet, the screw and the one-way ratchet are arranged in the inverted T-shaped cavity, and the bottom end of the screw extends out of the inverted T-shaped cavity, the screw and the inverted T-shaped cavity are movably matched, the one-way ratchet and the inverted T-shaped cavity are interference fit, the mating surface of the screw and the one-way ratchet is provided with a hexagonal rhombus, the screw and the one-way ratchet are meshed through the hexagonal rhombus, a screw hole is provided on one side of the inner ring of the top surface of the chassis of the I-shaped handwheel, and the bottom end of the guide rod is screwed into the screw hole. The device overcomes the defects of the traditional temporary deployment of warning tapes in specific places, ensures the flatness and tightening of the deployed warning tapes, and the seriousness of the warning area, and is easy to operate, thereby improving the efficiency of the deployment of warning tapes. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0012] Figure 1 This is a schematic structural diagram of a flattening and tightening device for a warning belt according to the utility model;

[0013] Figure 2 This is a cross-sectional schematic diagram of the I-shaped handwheel in this device. DETAILED DESCRIPTION

[0014] Implementation example Figure 1 and Figure 2 As shown, the utility model is used for the smooth tightening device of the warning belt, which includes an I-shaped handwheel 1, a guide rod 2, a one-way ratchet 3 and a screw 4. The chassis 11 of the I-shaped handwheel 1 is upwardly provided with an inverted T-shaped cavity 12, and the screw 4 penetrates the one-way ratchet 3. The screw 4 and the one-way ratchet 3 are arranged in the inverted T-shaped cavity 12, and the bottom end of the screw 4 extends out of the inverted T-shaped cavity 12. The screw 4 and the inverted T-shaped cavity 12 are movably matched, and the one-way ratchet 3 and the inverted T-shaped cavity 12 are interference fit. The mating surface of the screw 4 and the one-way ratchet 3 is provided with a hexagonal rhombus, and the screw 4 and the one-way ratchet 3 are meshed through the hexagonal rhombus. A screw hole 13 is provided on one side of the inner ring of the top surface of the chassis 11 of the I-shaped handwheel 1, and the bottom end of the guide rod 2 is screwed into the screw hole 13.

[0015] Preferably, the outer diameter of the screw 4 above the hexagonal rhombus is smaller than its circumscribed circle.

[0016] Preferably, a nut 5 is screwed onto the bottom end of the screw rod 4. The screw rod and the nut cooperate to fix the device in a hole of a fixed object at the security site.

[0017] Preferably, the device further comprises a sealing plate 6 , which penetrates into the bottom end of the screw 4 and is arranged on the bottom surface of the chassis 11 of the I-shaped handwheel 1 and abuts against the one-way ratchet 3 .

[0018] This device is a manual winding mechanism. After the warning tape is guided onto the I-shaped handwheel via a guide rod, the I-shaped handwheel is manually rotated. By wrapping the warning tape around a specific area of the I-shaped handwheel, the tape is tightened and maintained flat. The screw and I-shaped handwheel can be separated by plugging and unplugging, and the screw and ratchet are engaged by hexagonal diamond surfaces.

[0019] When using this device, first reliably connect the screw rod to the on-site fixture, or fix the device in the hole of the on-site fixture through the nut at the bottom of the screw rod, straighten the external warning tape, and introduce the warning tape into the I-shaped handwheel through the guide rod. The end of the warning tape needs to be prevented from falling off when introduced. Turn the handwheel to tighten the warning tape to an appropriate degree, and then insert the I-shaped handwheel into the screw rod. The screw rod engages with the one-way ratchet through the hexagonal diamond surface. The ratchet installed at the bottom of the I-shaped handwheel can achieve one-way rotation to tighten the warning tape, making the warning tape straight. When loosening the warning tape, remove the I-shaped handwheel from the screw rod.
