Detailed Embodiment

[0022] The present utility model will be further described below with reference to the accompanying drawings.

[0023] All the directions mentioned in this specification are based on the directions when a vehicle chassis frame with a binding device according to the present utility model is working properly, without limiting its directions during storage and transportation, only representing the relative positional relationship, not the absolute positional relationship.

[0024] As Figure 1 shown, a vehicle chassis frame with a binding device includes a frame body 1 extending forward and backward and a binding device 2 fixed on the frame body 1. A plurality of binding devices 2 are provided, and the plurality of binding devices 2 are symmetrically arranged on the left and right sides of the frame body 1.

[0025] A carriage (not shown in the figure) is fixedly installed on the vehicle chassis frame, and through holes can be selectively opened on the bottom plate of the carriage corresponding to the tying device 2. When purchasing a truck, through holes are not opened on the bottom plate of the carriage. The vehicle owner can selectively open through holes according to the types of goods to be transported (through holes are not required for bulk goods; while for packaged goods such as containers or transport vehicles, through holes are required).

[0026] By fixing the tying device 2 on the frame body 1, the fixing strength of the tying device 2 is improved, and its detachment is avoided; at the same time, the tying device 2 is not fixed or not separately fixed on the carriage bottom plate, thereby reducing the acting force between the tying device 2 and the carriage bottom plate, avoiding tearing of the carriage bottom plate, and improving the service life of the carriage bottom plate.

[0027] The frame body 1 includes a main beam 11 extending forward and backward, side beams 12 located on both sides of the main beam 11 and arranged parallel to the main beam 11, and cross beams 13 extending left and right and connecting the main beam 11 and the side beams 12. A plurality of cross beams 13 are evenly arranged along the extending direction of the main beam 11; the tying device 2 is fixed at the included angle position between the side beam 12 and the cross beam 13. By fixing the tying device 2 at the included angle position between the side beam 12 and the cross beam 13, the tying device 2 is clamped by the included angle, thereby improving the position accuracy and firmness of the tying device 2.

[0028] As Figure 1 、 Figure 2 and Figure 3 collectively shown, the tying device 2 includes a floor hook 21 that does not protrude from the upper surface of the frame body 1 and a support column 22 fixed to the bottom of the floor hook 21. The support column 22 is fixed to the frame body 1 through a fixing plate 3. By providing the support column 22 at the bottom of the floor hook 21, the periphery of the support column 22 is fixed to the frame body 1 through the fixing plate 3. The support column 22 increases the contact area between the tying device 2 and the frame body 1, making the fixation more firm. At the same time, the fixing point is moved downward. Using the lever principle, when the floor hook 21 is stressed, the stress at the welding position will be reduced, thereby avoiding the situation of detachment caused by the welding of the tying device 2 coming loose.

[0029] As Figure 2 shown, the fixing plate 3 includes a cross beam fixing plate 31 connecting the support column 22 and the cross beam 13 and a side beam fixing plate 32 connecting the support column 22 and the side beam 12. By fixing the support column 22 to the cross beam 13 and the side beam 12 respectively, the position accuracy and firmness of the support column 22 are improved, and detachment is avoided.

[0030] As Figure 3 and Figure 4As commonly shown, the floor hook 21 includes a fixed plate 211, a receiving groove 212 provided on the fixed plate 211, and a rotating hook 213 located within the receiving groove 212. On opposite side walls of the receiving groove 212, rotating shafts 214 are fixed, and the rotating hook 213 is rotatably mounted on the rotating shafts 214. By rotatably mounting the rotating hook 213 on the rotating shafts 214, when not in use, the rotating hook 213 can be rotated into the receiving groove 212, thus facilitating storage and avoiding interference with the goods in the carriage.

[0031] The size of the through-hole is smaller than that of the fixed plate 211 but not smaller than that of the receiving groove 212, so that the through-hole neither affects the rotation of the floor hook 21 out of the receiving groove 212, and at the same time, the periphery of the through-hole blocks the fixed plate 211. When the floor hook 21 is stressed, the entire disk surface of the fixed plate 211 forms a squeezing force with the periphery of the through-hole, changing the stress on the original weld seam to the current disk surface squeezing stress, increasing the stress area, reducing the local stress, and avoiding the deformation of the carriage floor due to stress.

[0032] To increase the positional accuracy and firmness of the floor hook 21 and the floor, and avoid rain leakage or dust entering through the middle gap, the periphery of the fixed plate 211 is welded to the floor.

[0033] Further, a slot 221 is provided inside the support column 22, and the receiving groove 212 is inserted into the slot 221. The top of the slot 221 abuts against the bottom of the fixed plate 211 and is welded to the fixed plate 211.

[0034] The inner wall of the slot 221 has the same size as the outer wall of the receiving groove 212. When the receiving groove 212 is inserted into the slot 221, the outer wall of the receiving groove 212 is arranged in close contact with the inner wall of the slot 221. With this structure, the contact area between the support column 22 and the floor hook 21 can be increased, the stress area can be enlarged, the local stress can be reduced, and the detachment between the two can be avoided.

[0035] On opposite side walls of the slot 221 relative to the rotating shafts 214, rotating holes 222 are provided, and the rotating shafts 214 are fixed within the rotating holes 222. The rotating shafts 214 are fixed not only on the floor hook 21 but also on the support column 22, so that part of the stress on the rotating shafts 214 is directly transmitted to the support column 22, reducing the stress between the receiving groove 212 and the slot 221. At the same time, the support column 22 and the floor hook 21 are connected as a whole through the rotating shafts 214, avoiding the detachment between the two.

[0036] To ensure that when not in use, the rotating hook 213 is always located within the receiving groove 212 and avoid the collision between the rotating hook 213 and the receiving groove 212 due to vehicle vibration, thus generating noise, a torsion spring (not shown in the figure) is provided between the rotating hook 213 and the rotating shafts 214.

[0037] In another embodiment, in order to avoid the difficulty in assembling the torsion spring and to provide an assembly space for the torsion spring, which causes the problem of the large size of the floor hook 21, a magnet is provided at the bottom of the receiving groove 212, and the rotary hook 213 is adsorbed on the magnet. The rotary hook 213 is adsorbed in the receiving groove 212 by magnetic attraction.

[0038] The vehicle chassis frame with a binding device of the present utility model solves the technical problems in the prior art that all the tensile forces borne by the floor hook are concentrated on the floor of the carriage. Over time, it is easy to cause tearing and damage to the floor of the carriage and the detachment of the floor hook. By fixing the binding device on the frame body, the present utility model improves the fixing strength of the binding device and avoids its detachment; at the same time, the binding device is not fixed or not separately fixed on the floor of the carriage, thereby reducing the acting force between the binding device and the floor of the carriage, avoiding the tearing of the floor of the carriage, and improving the service life of the floor of the carriage.

[0039] Of course, the above description is not a limitation of the present utility model, and the present utility model is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the substantial scope of the present utility model should also fall within the protection scope of the present utility model.
