Detailed Description

Referring to fig. 1 to 5, the tightening structure for connecting the carriage frame and the vehicle body according to the present invention is used for connecting a carriage frame and a tail towing pipe 20 to tightly and fixedly connect the carriage frame and the tail towing pipe, and the detailed structure of the present invention is described as follows:

as shown in fig. 1 to 2, 4, 5, 6, 7, 8, 9, 10, and 11, a fixing rod frame 10 is connected to a carriage body (not shown), and if the fixing rod frame 10 is a tube with a square cross section, two slots 11 are formed at a predetermined position of a corner edge, and a through hole 12 is formed between the two slots 11.

As shown in fig. 1 to 2, 4, 5, 6 and 7, a tail pipe 20 has one end connected to a vehicle body (not shown), the other end for being sleeved on the fixing rod frame 10, the tail pipe 20 having a braking hole 21, the braking hole 21 corresponding to the through hole 12, and a fine tuning screw 30 passing through the braking hole 21 and the through hole 12 to fix the fixing rod frame 10 and the tail pipe 20.

As shown in fig. 1 to 7, a packing structure 40, the packing structure 40 is provided with a body 41, two slots 411 are provided at predetermined positions of one side of the body 41, and a fine adjustment cam 42 is provided on each slot 411; the body 41 is provided with an arc groove 43 opposite to the other end provided with the slots 411, a fine adjustment member 44 capable of moving along the arc groove 43 is arranged on the arc groove 43, the body 41 is provided with a fine adjustment hole 45, and the fine adjustment member 44 is used for driving the body 41 to perform fine adjustment turning.

In the use state of the present invention, referring to fig. 4 to 11, the aforementioned tightening structure 40 is installed inside the fixing rod frame 10, and the two fine adjustment cams 42 are protruded slightly from the two slots 11; when in use, the tail pipe 20 is sleeved on the fixed rod frame 10, and the fine adjustment screw 30 is used for locking and positioning after the fine adjustment screw 30 penetrates through the braking hole 21, the through hole 12 and the fine adjustment hole 45; in addition, when locking and positioning, the fine adjustment screw 30 drives the fine adjustment member 44 to perform fine adjustment displacement, and the relative position between the fine adjustment member 44 and the fine adjustment screw 30 can drive the body 41 to perform fine adjustment to enable the two fine adjustment cams 42 to protrude out of the two slot holes 411, in this state, the body 41 contacts the inner wall surface of the fixed rod frame 10, the two fine adjustment cams 42 contact the inner wall surface of the trailer pipe 20, and the fine adjustment cams 42 contact the inside of the trailer pipe 20, so that the purpose of restraining and braking is achieved, and the occurrence of shaking of the vehicle carrying frame in the transportation process is prevented.

To further illustrate the structural details of the tightening structure 40, as shown in fig. 3 to 11, the cross section of the body 41 is an irregular quadrilateral, for convenience of description, the body 41 has at least two first faces 4A and a second face 4B for tightening the inner wall surface of the fixing rod frame 10, the boundary between the first face 4A and the second face 4B is a borderline, the aforementioned fine adjustment cam 42 is disposed on the borderline, and a pivot 46 penetrates through the two fine adjustment cams 42, so that the fine adjustment cams 42 can rotate.

Referring to fig. 4 and 5, as shown in fig. 4, when the assembly is started, the fastening structure 40 is installed on the fixed rod frame 10, and then the trailer 20 is sleeved on the outer side of the fixed rod frame 10; then, the fine adjustment screw 30 is inserted into the rear towing pipe 20, the fixing rod frame 10, the body 41 and the fine adjustment member 44, the fine adjustment screw 30 penetrates out of the rear towing pipe 20, and the fine adjustment screw 30 is restrained and limited by a nut; in this state as shown in fig. 5, the first surface 4A and the second surface 4B are not yet in close contact with the inner wall surface of the fixing rod frame 10, and therefore, the first surface 4A and the second surface 4B are slightly spaced from the inner wall surface.

As shown in fig. 6, a tool is used to screw the fine adjustment screw 30, as shown in fig. 6, when the fine adjustment screw 30 is screwed, the packing member 44 generates a packing action on the body 41, and the first surface 4A and the second surface 4B are pushed and sealed towards the inner wall surface of the fixing rod frame 10 by the cooperation of the arc-shaped groove 43 and the packing member 44; as shown in fig. 7, the two trimming cams 42 driven by the body 41 are driven by the body 41 to contact with the inner wall surface side of the trunk pipe 20.

Referring to fig. 8, by continuously rotating the fine adjustment screw 30, the first surface 4A and the second surface 4B of the body 41 are already sealed on the inner wall surface of the fixing rod frame 10, but the lower end has a slight gap, as shown in fig. 9, when the fine adjustment screw 30 is continuously rotated to seal the body 41 towards the inner wall surface of the fixing rod frame 10, the two further fine adjustment cams 42 are shifted from only the contact side of fig. 7 to the state of fig. 9, and the two fine adjustment cams are supported against the two sides of the upper end of the trailer tube 20.

As shown in fig. 10 and 11, when the fine adjustment screw 30 is rotated until it cannot be rotated, as shown in fig. 10, since the body 41 is already tightly adhered to the inner wall surface of the fixing rod frame 10, in this state, as shown in fig. 11, the fine adjustment cam 42 is abutted against the upper end of the rear towing pipe 20, so that the body 41 slightly fills up the gap downward, and thus three surfaces of the body 41 are attached to the inner wall surface of the fixing rod frame 10, and the two fine adjustment cams 42 are abutted against the upper end of the rear towing pipe 20, so that the fixing rod frame 10 and the rear towing pipe 20 can be constrained at multiple points, and therefore, the carriage frame assembled on the fixing rod frame 10 can move left and right but is not in a stable state of shaking.

From the above description, the present invention utilizes the fine adjustment screw 30 to drive the tightening structure 40 to restrain and brake the fixed rod frame 10 and the trailer 20, so as to prevent the occurrence of shaking and abnormal sound during transportation of the vehicle-carrying frame, and improve the safety of the whole structure.

It should be understood that the above-described technical principles which are immediately applicable to the implementation of the present invention are all within the scope of the present invention, and the functions thereof should be understood to be within the scope of the present invention if the technical principles are changed according to the idea of the present invention and the functions thereof are not beyond the spirit of the present invention covered by the description and the attached drawings.
