Car carrier binder

Abstract

The invention provides a car carrier binder and belongs to the technical field of logistics binding tools. A problem that a car carrier binder is inconvenient to operate in the prior art is solved. The car carrier binder comprises a mounting plate and a propping plate which is used for propping against a wheel; a side plate I and a side plate II which are oppositely arranged are fixedly connectedto one side surface of the propping plate; the mounting plate is correspondingly connected with the side edge of the side plate I and the side edge of the side plate II; a winding shaft used for winding a binding strap is rotationally arranged between the side plate I and the side plate II; one end of the winding shaft penetrates out of the side plate I and connected with a worm gear; a worm engaged with the worm gear is arranged on the external side surface of the side plate I; a driving piece is arranged on the external side surface of the side plate II; and a transmission structure used forenabling the driving piece to be able to drive the worm to rotate is arranged on the side surface of the mounting plate. The car carrier binder has the advantages of convenient use and compact structure.

Description

technical field [0001] The invention belongs to the technical field of logistics binding tools, and relates to a binding device for a car transport vehicle. Background technique [0002] During the transportation of the vehicle by truck, ship or train, the vehicle needs to be secured. The car binding device is a device that fixes the wheels of the vehicle to prevent the vehicle from moving arbitrarily during transportation. [0003] For example, the Chinese patent literature discloses an automatic take-up mechanism for a wheel holder (application number: 201710048105.8; publication number: CN106799986A). A fastening belt is wound on the reel, a ratchet is fixed on the reel, and a lock is hinged on the casing, and the lock has a pawl. In the process of fixing the vehicle, the wheel fixer realizes the tightening of the binding belt by the operator rotating the reel with the help of a tool. During the use of such a wheel anchor, since the wheel anchor is placed on the truck ...

Problems solved by technology

However, since the motor, worm shaft, worm gear and transmission mechanism are all arranged on the same side of the support in this device, some distance needs to be reserved between the motor and the worm shaft to realize the installation of the transmission mechanism. , including the bracket, worm gear mechanism, motor, and the reserved distance between the motor and the worm shaft, resulting in a long length of the device and a large overall footprint, which affects the convenience of use

Moreover, when the motor drives the worm shaft to rotate, in order to achieve a greater binding force, multiple sets of gears need to be set between the motor shaft and the worm for deceleration transmission, so as to achieve a greater binding force under the premise of a certain output torque of the motor. , however, the space required for setting multiple sets of gears will be large, so if the belt retracting device wants to achieve greater binding force, it is also necessary to increase the distance between the motor and the worm shaft to set more gears , which will lead to a further increase in the size of the device, therefore, the structural design of the device is difficult to achieve comprehensive optimization of binding force and space design
