[0018] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0019] A preferred embodiment of a trolley suspension device for a truck of the utility model is as follows: Figures 1 to 3 As shown, the trolley suspension device for a truck includes a hook 100, and there are at least two hooks 100, and the hooks 100 are arranged at intervals in the horizontal direction. Increasing the number of hooks 100 can increase the stability of the trolley 200 when it is suspended. In this embodiment, there are two hooks 100, and the farthest distance between the hooks 100 in the horizontal direction is equal to the width of the handrail 202 of the trolley 200, so that when the trolley 200 is suspended on the hook 100, the hook 100 contacts the handrail 202 of the trolley 200, limits the horizontal position of the trolley 200, prevents the trolley 200 from moving in the horizontal position on the hook 100, and reduces the collision between the trolley 200 and the carriage and the goods.
[0020] The hook 100 includes a base 1 and a pressure plate 2, wherein the base 1 is used to be fixedly mounted on the inner wall of the tailgate of a truck. The inner wall of the tailgate of a van is usually a concave structure, and the hook 100 is fixedly mounted on the inner wall of the tailgate, so that the space between the tailgate and the cargo can be reasonably utilized, thereby avoiding occupying the cargo space and causing space waste. At the same time, it is also convenient to take and place the trolley 200 when the tailgate is opened for loading cargo.
[0021] The pressing plate 2 is rotatably mounted on the base 1. The pressing plate 2 can rotate in a vertical plane, that is, the rotation axis of the pressing plate 2 is a horizontal line. There is also a receiving space between the pressing plate 2 and the base 1 for receiving the connecting shaft 203 of the trolley 200. The receiving space is provided with a support member 3. The support member 3 is fixedly assembled with the base 1. The support member 3 is used to support the connecting shaft 203 of the trolley 200. When the trolley 200 is hung, the connecting shaft 203 can be hung in the receiving space after the trolley 200 is folded, and the weight of the trolley 200 is borne by the support member 3, and the weight is transmitted to the base 1 and the tailgate via the support member 3.
[0022] A return spring 4 is also connected between the pressure plate 2 and the base 1. The return spring 4 is used to apply an elastic force to the pressure plate 2 toward the base 1. The elastic force enables the pressure plate 2 to press the connecting shaft 203 of the trolley 200, squeeze the connecting shaft 203 onto the base 1, limit the position of the trolley 200, avoid the trolley 200 from swinging sharply after being hung, and reduce the damage and deformation of the items caused by collision with the goods.
[0023] The trolley hanging device for a truck is provided with at least two hooks 100 on the inner wall of the tailgate of the truck to form a hanging device. When the trolley 200 is not hung, the return spring 4 drives the pressing plate 2 to rotate and fit the base 1 through elastic force, so that the loading space occupied by the hook 100 can be reduced. When the trolley 200 is hung, the trolley 200 is folded and the connecting shaft 203 is assembled in the accommodating space between the pressing plate 2 and the base 1. The connecting shaft 203 is supported by the support member 3 to bear the weight of the trolley 200. The return spring 4 applies elastic force to the pressing plate 2, and the pressing plate 2 presses the connecting shaft 203 toward the base 1 to position the trolley 200, thereby reducing the shaking of the trolley 200 and damaging of the articles, and at the same time, the space on the tailgate of the vehicle is reasonably utilized to reduce space waste.
[0024] Preferably, the support member 3 includes a support rod 31 , one end of which is fixedly assembled on the base 1 , and there are two support rods 31 , which are respectively located on both sides of the pressing plate 2 in the width direction.
[0025] The support member 3 includes two support rods 31 located on both sides of the pressure plate 2 in the width direction. The support rods 31 are located on both sides of the pressure plate 2 to avoid interference with the pressure plate 2. At the same time, the two support rods 31 can also form multi-point support for the connecting shaft 203, increase stability, and reduce the shaking of the trolley 200.
[0026] Preferably, the support member 3 also includes a baffle rod 32, which is connected to one end of the two support rods 31 away from the base 1. The baffle rod 32 and the two support rods 31 form a U-shaped structure. The baffle rod 32 is located on the side of the pressure plate 2 away from the base 1, and there is a gap between the baffle rod 32 and the pressure plate 2 for the pressure plate 2 to swing in a direction away from the base 1.
[0027] The stopper bar 32 of the support member 3 is connected to the support bar 31 to form a U-shaped structure. The stopper bar 32 can limit the rotation angle of the pressing plate 2. When the trolley 200 overcomes the elastic force of the reset spring 4 and pushes the pressing plate 2 to swing, the stopper bar 32 can lock the pressing plate 2 to prevent the trolley 200 from completely flattening the pressing plate 2 and then falling off. There is a gap between the stopper bar 32 and the pressing plate 2, and the gap allows the pressing plate 2 to swing to a certain angle. When the trolley 200 is hung on the hook 100, the operator can push the pressing plate 2 by hand to increase the size of the top of the accommodation space, which is convenient for hanging.
[0028] Preferably, the angle between the pressing plate 2 and the base 1 during the swing stroke is in the range of 90-120 degrees.
[0029] The angle between the pressing plate 2 and the base 1 is maintained at 90-120 degrees during the swing stroke. If the angle is too small, the size of the accommodating space will be small, affecting the suspension of the trolley 200; if the angle is too large, the pressing plate 2 will tilt too much, and the trolley 200 will be at risk of falling off.
[0030] Preferably, the base 1 includes a bottom plate 11, a hinge seat 12 and a hinge shaft 13, the bottom plate 11 is used to be welded and fixed to the inner wall of the tailgate of the truck, the hinge seat 12 is fixedly assembled at the bottom of the bottom plate 11, the hinge shaft 13 is rotatably assembled on the hinge seat 12, the pressure plate 2 is fixedly assembled with the hinge shaft 13, the support member 3 is fixedly assembled with the bottom plate 11, and the return spring 4 is connected between the bottom plate 11 and the pressure plate 2.
[0031] The base 1 is formed by a bottom plate 11, an articulated seat 12 and a hinge shaft 13. The hinge shaft 13 has a small friction area, which can reduce friction and ensure smooth rotation of the pressing plate 2. In this embodiment, the articulated seat 12 is a U-shaped structure, and the articulated seat 12 is separately arranged on the bottom plate 11. The articulated seat 12 allows a certain distance between the hinge shaft 13 and the bottom plate 11, and the distance can provide an accommodation space between the pressing plate 2 and the bottom plate 11 for accommodating the connecting shaft 203.
[0032] Preferably, the support member 3 is located on the upper side of the return spring 4 , and the return spring 4 is located between the support member 3 and the hinge shaft 13 .
[0033] The return spring 4 is located between the support member 3 and the hinge shaft 13 . The support member 3 bears the weight of the trolley 200 , thereby protecting the return spring 4 and preventing the return spring 4 from being squeezed and damaged by the trolley 200 .
[0034] Preferably, a protective cover 21 is further provided on the surface of the pressing plate 2 .
[0035] The protective cover 21 can protect the pressing plate 2 and the trolley 200 from being scratched, and also has the functions of increasing the friction between the connecting shaft 203 and the pressing plate 2, preventing shock and reducing noise. In this embodiment, the pressing plate 2 is made of stainless steel, and the protective cover 21 is made of PVC.
[0036] In summary, the embodiment of the utility model provides a trolley hanging device for a truck, which has at least two hooks installed on the inner wall of the tailgate of the truck to form a hanging device. When the trolley is not hung, the return spring drives the pressure plate to rotate and fit the base through elastic force, so that the loading space occupied by the hooks can be reduced; when the trolley is hung, the connecting shaft is assembled in the accommodating space between the pressure plate and the base after the trolley is folded, and the connecting shaft is supported by the support member to bear the weight of the trolley. The return spring applies elastic force to the pressure plate, and the pressure plate presses the connecting shaft toward the base to position the trolley, thereby reducing the shaking of the trolley and damage to the items, while also making rational use of the space on the tailgate of the vehicle to reduce space waste.
