Description

Technical Field

[0001] The utility model relates to the technical field of logistics equipment, specifically an elastic bolting device for a van Background Art

[0002] In order to prevent the door panels of vans from automatically closing or shifting due to external forces such as wind and self-weight displacement when loading and unloading goods, causing damage to personnel and goods, they must be bolted after the door is opened. Currently, metal wind hooks and wind hook seats are commonly used. The wind hooks are fixed to the door panels with rivets, and the wind hook seats are fixed to the side walls with rivets. This method requires drilling holes and installing rivets on the door panels and side wall panels. The perforated parts are prone to water leakage and rust, and the tail of the rivets is prone to scratching the goods. In order to simplify the bolting process, some users use metal chains and hooks in combination. The chain is fixed to the back of the car floor, and the hook is welded to the inside of the door panel. When bolting, after opening the door panel, the chain ring bolt is hung in the hook. This method is a soft connection. Due to the limitation of the chain pitch, the door panel cannot be stably bolted to the side wall, and the chain swings freely during driving, which increases driving noise.

[0003] In order to solve the above problems, the Chinese patent document "A punch-free installation vehicle door panel bolting device" (patent application number: 201821147247.6) discloses a punch-free installation vehicle door panel bolting device, which directly uses the bolt rod as the bolting point, and does not require drilling holes on the side panels and door panels to install additional bolting devices, which completely solves the hidden dangers of perforation and water leakage in the vehicle body, and the appearance quality and sealing effect are stably guaranteed.

[0004] However, in the above solution, since the bolting device is designed on the outside of the door panel, it not only affects the appearance and occupies space, but also has problems of sun aging and loss. Utility Model Content

[0005] In view of the defects existing in the prior art, the purpose of the utility model is to provide an elastic bolting device for a van, which does not require drilling holes in door panels or side walls for installation, thus eliminating the risks of water leakage and rust. At the same time, whether it is storing itself or bolting the door panel, the elastic rope is in a taut state under the action of elastic force, and will not produce shaking or abnormal noise. Moreover, the bolting device is inside the car, so there is no need to worry about sun aging and loss, and the service life is greatly extended.
