Description

Technical Field

[0001] The utility model relates to the technical field of trolleys, in particular to a flat-plate logistics trolley. Background Art

[0002] Hand-pushed flatbed logistics vehicles are mainly used to transport goods in workshops. However, during the transportation process of the flatbed logistics vehicles, the goods carried on the flatbed logistics vehicles are prone to falling due to turning, sudden stops, etc.

[0003] In the existing patent literature, there is a patent with the publication number CN 208344276 U and the name of "Logistics Vehicle". Although the patent has multiple binding and positioning rings installed on the side of the vehicle body, binding ropes are still needed in actual application. The staff needs to find the binding ropes and fix the binding knots on the binding and positioning rings to fix the goods. The operation is relatively cumbersome and inconvenient in application. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a flatbed logistics trolley, which can launch a binding rope through a self-locking binding rope launching component when in use. The binding rope passes over the top of the goods and is introduced into a limiting binding rope receiving component. The binding rope can then be self-locked and fixed. The goods are bound and fixed through multiple binding ropes, which provides stability for the goods during transportation. Since the binding rope is rolled up in the self-locking binding rope launching component, it can be directly pulled out for use when in use, which is more convenient to use.

[0005] In order to solve the above technical problems, the technical solution of the utility model is implemented as follows:

[0006] A flatbed logistics trolley comprises a main seat, one end of which is rotatably provided with a push handle, and four corners of the bottom of the main seat are respectively fixedly provided with universal casters;

[0007] A plurality of self-locking rope transmitting assemblies distributed in a linear array are fixedly installed on any two adjacent sides of the main seat, and the remaining two adjacent sides of the main seat are fixedly installed with position-limiting rope receiving assemblies corresponding to the positions of the self-locking rope transmitting assemblies and equal in number;

[0008] The self-locking rope launching assembly comprises a rope launching positioning frame, a retractor is installed at the bottom of the rope launching positioning frame, a binding rope is elastically rolled up in the retractor, an outer end of the binding rope is fixedly connected to a limit stopper, and the limit stopper pulls the binding rope to abut against the top of the rope launching positioning frame;

[0009] The limited rope receiving assembly includes a rope receiving and positioning frame, and a vertical and downward rope guide groove is opened on the outer side surface of the rope receiving and positioning frame. The limited stopper can pull the binding rope into the rope guide groove, and then the limited stopper is stuck on the inner side surface of the rope receiving and positioning frame;

[0010] The flatbed logistics trolley is used to transport goods. The goods are placed on the upper surface of the main seat. The binding ropes should pass over the top of the goods when binding, and finally the goods are bound and fixed by multiple criss-crossing binding ropes.

[0011] By adopting the above scheme, the flatbed logistics trolley is used for the transportation of logistics goods. When the goods are placed on the main seat for transportation, the binding rope can be launched through the self-locking binding rope launching component, and the binding rope is passed around the top of the goods and introduced into the limiting binding rope receiving component. Then the binding rope can be self-locked and fixed, and the goods are bound and fixed through multiple binding ropes, which provides stability for the goods during transportation; because the binding rope is rolled up in the self-locking binding rope launching component, it can be directly pulled out for use when in use, which is more convenient to use.

[0012] As a preferred embodiment of a flatbed logistics trolley, a rope locking block 1 and a rope locking block 2 are installed inside the rope launching and positioning frame, and the binding rope is located between the rope locking block 1 and the rope locking block 2; the rope locking block 1 is fixedly connected to the inner wall of the rope launching and positioning frame, and the rope locking block 2 is slidably connected to a guide shaft fixed on the inner wall of the rope launching and positioning frame; the side of the rope launching and positioning frame close to the rope locking block 2 is threadedly matched with a top screw, and the top head of the top screw can contact the rope locking block 2;

[0013] A plurality of grooves are arranged on the side of the rope locking block 1 facing the location of the rope locking block 2, and a plurality of protrusions are arranged on the side of the rope locking block 2 facing the location of the rope locking block 1, and the protrusions and the grooves fit each other;

[0014] The binding rope is a soft rope, and the binding rope can be locked by the mutually fitting protrusions and grooves;

[0015] Among them, the protrusion is a curved surface protrusion; and the groove is a curved surface groove.

[0016] By adopting the above scheme, in order to achieve the locking of the binding rope, the binding rope is placed between the binding rope locking block one and the binding rope locking block two. By rotating the top screw, the top screw can continuously push the binding rope locking block two, and finally the binding rope is clamped between the binding rope locking block one and the binding rope locking block two through the protrusion and the groove, thereby achieving the locking of the binding rope; since the surfaces of the protrusion and the groove are both curved surfaces, the two will not cause damage to the binding rope even when they fit together, thereby extending the service life of the binding rope.

[0017] As a preferred implementation of a flatbed logistics trolley, a spring is also mounted on the guide shaft to push the rope locking block to move toward the location of the top screw.

[0018] By adopting the above scheme, in order to realize the resetting of the rope locking block 2, a spring is provided. When the top wire is retracted, the rope locking block 2 will automatically reset under the elastic action of the spring.

[0019] As a preferred embodiment of a flatbed logistics trolley, the top head of the top screw is a round head.

[0020] By adopting the above scheme, in order to reduce the friction between the top screw and the rope locking block 2, the top head of the top screw is designed to be a round head, and the contact area between the two is very small, which will save more effort when rotating the top screw.

[0021] As a preferred embodiment of a flatbed logistics trolley, a limit groove located on the rope guide groove is provided on the inner side surface of the rope receiving and positioning frame; two symmetrical anti-deflection slots are provided around the limit groove, and two symmetrical anti-deflection plugs are fixed on the side of the limit stop head; the limit stop head can abut against the limit groove, and the anti-deflection plug can be limited and matched with the anti-deflection slot.

[0022] By adopting the above scheme, in order to ensure that the limit stopper is stably stuck on the rope receiving positioning frame, the anti-deflection plugs on both sides of the limit stopper are respectively assembled in the anti-deflection slots. At this time, the limit stopper cannot move and is firmly stuck on the rope receiving positioning frame.

[0023] As a preferred implementation of a flatbed logistics trolley, a dirt storage box is also installed at the bottom of the main seat, and a plurality of hollow grooves connected to the dirt storage box are provided on the surface of the main seat.

[0024] By adopting the above scheme, in order to prevent liquid from flowing onto the ground due to the breakage of goods, a dirt storage box is provided, and the leaked liquid will flow from the hollow groove into the dirt storage box for temporary storage, thereby avoiding affecting the environment.

[0025] After adopting the above technical solution, the beneficial effects of the utility model are:

The goods are tied and fixed through multiple binding ropes, which provides stability for the goods during transportation. Since the binding rope is rolled up in the self-locking binding rope launching component, it can be directly pulled out when used, which is more convenient to use.

[0027] 2. In order to lock the binding rope, the binding rope is placed between the binding rope locking block 1 and the binding rope locking block 2. By rotating the top screw, the top screw can continuously push the binding rope locking block 2, and finally the binding rope is clamped between the binding rope locking block 1 and the binding rope locking block 2 through the protrusion and the groove, thereby locking the binding rope; since the surfaces of the protrusion and the groove are both curved surfaces, the binding rope will not be damaged even when the two are in contact, thereby extending the service life of the binding rope;

[0028] 3. In order to realize the reset of the rope lock block 2, a spring is set. When the top wire is retracted, the rope lock block 2 will automatically reset under the elastic action of the spring;

[0029] 4. In order to ensure that the limit stopper is stably stuck on the rope receiving positioning frame, the anti-deflection plugs on both sides of the limit stopper are respectively assembled in the anti-deflection slots. At this time, the limit stopper cannot move and is firmly stuck on the rope receiving positioning frame;

The limited stopper 404 can pull the binding rope 403 into the rope guiding groove 502, and then the limited stopper 404 is stuck on the inner side surface of the rope receiving positioning frame 501;

[0050] The flatbed logistics trolley is used to transport goods 6, which are placed on the upper surface of the main seat 1. The binding ropes 403 should pass over the top of the goods 6 when binding, and finally the goods 6 are bound and fixed by multiple criss-crossing binding ropes 403.

[0051] The flatbed logistics trolley is used for transporting logistics goods 6. When the goods 6 are placed on the main seat 1 for transportation, the binding rope 403 can be launched through the self-locking binding rope launching component 4. The binding rope 403 passes over the top of the goods 6 and is introduced into the limiting binding rope receiving component 5. Then the binding rope 403 can be self-locked and fixed. The goods 6 are bound and fixed through multiple binding ropes 403, which provides stability for the goods 6 during transportation. Since the binding rope 403 is rolled up in the self-locking binding rope launching component 4, it can be directly pulled out for use when in use, which is more convenient to use.
