Problems solved by technology

[0003] In view of the above problems, the patent document (application number: 00219256.X) discloses a vehicle transport fastener, one end of the fastening belt has an end hook, and the end hook is arranged at the cover of the flexible wedge, and is composed of two side plates and The tape shell composed of circular arc plates, the flexible pad mounted on the circular arc plates, the rotating shafts, pawls, tape guide shafts installed and connected to the two side plates, and the telescopic hooks at the bottom constitute the tape tape fixing device, and the ratchets are fixed on the On the rotating shaft, the first connecting rod hinged on both sides of the telescopic hook and the second connecting rod hinged with the hook are hinged through the belt passing shaft, and the fastening belt on the belt guiding shaft is closely attached to the belt passing shaft. One end is fixed on the rotating shaft, but after the fastener is used, the pulled out fastening belt needs to be retracted, that is, the belt shaft needs to be manually rotated to take up the fastening belt, which is not only complicated to operate, but also very slow

Embodiment 1

[0031] like figure 1 , figure 2 As shown, an automatic take-up mechanism of a wheel holder, the wheel holder includes a housing 1, a reel 2 is rotatably connected to the housing 1, and a fastening belt 21 is wound on the reel 2, and the fastening belt 21 is located in the housing 1, a ratchet 3 is fixedly connected to the reel 2, and each ratchet of the ratchet 3 has a positioning surface 31 and a guiding surface 32. The housing 1 is hinged with a locking piece 4, the locking piece 4 has a pawl 42, a locking lever 43 and a counterweight 44, the three are firmly connected, an angle is formed between the locking lever 43 and the pawl 42, and the matching The weight 44 and the locking rod 43 are located on both sides of the ratchet 42. The locking rod 43 has a pushing arc surface 431 and an abutting surface 432 respectively. The resting surface 432 is located at the end of the locking rod 43 . like image 3 As shown, it is the state of the housing 1 when the fastening belt 2...

Embodiment 2

[0034] The automatic take-up mechanism of this wheel holder is basically the same as Embodiment 1, the difference is that Figure 8 As shown, the locking member 4 also includes a counterweight rod 45, the two ends of the counterweight rod 45 are rotatably connected to the inner wall of the housing 1, and the locking rod 43 and the pawl 42 are all fixedly connected to the counterweight rod 45. At the end, the middle part of the counterweight rod 45 is bent to form a protruding counterweight part 46 , without additional counterweight 44 .

Abstract

In the present automatic strap retracting mechanism for wheel restraint devices, the wheel restraint device comprises a shell (1), and a reel (2) is rotatably connected inside the shell. A ratchet (3) is fixed to the reel, and the tooth surface of the ratchet consists of a locating surface (31) and a guiding surface (32). A locking piece(4) is also hinged to the shell, and the locking piece has a pawl (42). The automatic strap retracting mechanism comprises a coil spring which is connected to the reel and can drive the reel to rotate in the direction of strap retracting and wind in and retract the fastening strap. The locking piece also comprises a locking rod (43). When the pawl detaches from the locating surface and the fastening strap is pulled out, the locking piece can swing to allow the locking rod to abut on the guiding surface.

Description

technical field [0001] The invention belongs to the technical field of vehicle auxiliary equipment, and relates to an automatic tape-rewinding mechanism of a wheel holder. Background technique [0002] During the process of transporting the vehicle by land or sea, the vehicle needs to be fixed. The wheel fixer is a device that fixes the tires of the vehicle to prevent the vehicle from moving freely during transportation. It usually includes a shell and a fastening belt. The shell is connected with a hook body for hooking on the carrier. The fastening belt is connected to the reel of the housing and is connected with a hook body. After the fastening belt is pulled out, the fastening belt goes around the wheel and is hooked on the carrier, so that the wheel is held and fixed by the fastening belt. [0003] In view of the above problems, the patent document (application number: 00219256.X) discloses a vehicle transport fastener, one end of the fastening belt has an end hook, a...
