DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the following further describes how the present invention is implemented in conjunction with the accompanying drawings and specific implementation methods.

[0025] See also Figures 1 to 9 The utility model provides a multi-purpose hinge structure for a flatbed truck, comprising a first flip hinge 1, a second flip hinge 2, a flip latch 3 and a fixed hook seat 4; wherein the first flip hinge 1 is fixed to the compartment flatbed 6 of the flatbed truck, and can be separated from the fixed hook seat 4 or locked together with the fixed hook seat 4 through the second flip hinge 2 and the flip latch 3; the fixed hook seat 4 is fixed to the compartment floor 7 of the flatbed truck, and can be separated from or locked together with the first flip hinge 1, the second flip hinge 2 and the flip latch 3; the second flip hinge 2 is rotatably connected to the side of the first flip hinge 1 away from the compartment flatbed 6, and can be locked together with the first flip hinge 1 and the fixed hook seat 4 through the flip latch 3; the flip latch 3 is fixed to the lower end of the second flip hinge 2, and can be rotatably matched with the first flip hinge 1 and the fixed hook seat 4.

[0026] In practical applications, the multi-purpose hinge structure provided by the utility model is specifically used in conjunction with the upper door latch structure (composed of the upper door latch 8 and the upper door latch lock 9), that is, the multi-purpose hinge structure is installed at the lower part of the compartment railing 6 of the railing type truck, and the upper door latch structure is installed at the upper part of the compartment railing 6 of the railing type truck; when the upper door latch structure is opened, the compartment railing 6 of the railing type truck will be flipped open from top to bottom with the multi-purpose hinge structure as the flip axis, see Figure 7 When the multi-purpose hinge structure is opened, the railing of the vehicle compartment of the railing type truck 6 will be turned over from bottom to top with the door latch structure as the turning axis, see Fig. 9 shown.

[0027] Specifically, as a specific embodiment of the utility model: one end of the second flip hinge 2 is rotatably connected to the first flip hinge 1 through the pin 5, and the other end can be rotated with the flip latch 3 with the pin 5 as the rotation axis downward toward or upward away from the fixed hook seat 4, see Figure 3 shown.

[0028] When the second flip hinge 2 rotates downward with the pin 5 as the rotation axis (rotates in the direction close to the fixed hook seat 4), the flip latch 3 will fall into the slots of the first flip hinge 1 and the fixed hook seat 4, so that the second flip hinge 2 and the first flip hinge 1 are bolted to the fixed hook seat 4. Figure 1 As shown; if used with the compartment fence 6 in this state, when the upper door latch structure at the upper end of the compartment fence 6 is opened, the compartment fence 6 can be tilted toward the fixed hook seat 4 together with the first flip hinge 1 and the second flip hinge 2 until they collide with the fixed hook seat 4, thereby completing the top-down flipping and opening of the compartment fence 6 of the compartment truck, see Figure 2 and Figure 7 As shown;

[0029] When the second flip hinge 2 rotates upward with the pin 5 as the rotation axis (rotates in the direction away from the fixed hook seat 4), the flip latch 3 will leave the slots of the first flip hinge 1 and the fixed hook seat 4, so that the second flip hinge 2 and the first flip hinge 1 are disconnected from the fixed hook seat 4. Figure 3 If in this state and the carriage fence 6 is used, the carriage fence 6 can pass through the fixed hook seat 4 with the first flip hinge 1 and the second flip hinge 2, so that the carriage fence 6 of the fence-type truck can be flipped open from bottom to top, see Figure 4 and Figure 8 shown.

[0030] Specifically, as a specific embodiment of the present invention: Figure 5 The first flip hinge 1 includes a flip hinge body 101, a first U-shaped opening 102 for allowing the fixed hook seat 4 to pass through is opened in the middle of the flip hinge body 101, two semi-circular arc hook blocks 103 are arranged at the lower part of the flip hinge body 101, and the two semi-circular arc hook blocks 103 are symmetrically arranged on both sides of the first U-shaped opening 102, for supporting the flip pin 3 and allowing the fixed hook seat 4 to pass through, and an ear plate 104 is arranged on one side of the flip hinge body 101 for fixing the pin 5.

[0031] Specifically, as a specific embodiment of the utility model: a second U-shaped opening 201 is opened in the middle of the second flip hinge 2, and a flip latch 3 is fixed at the open end of the second U-shaped opening 201; wherein, when the second flip hinge 2 is locked with the fixed hook seat 4, the first flip hinge 1 is straddled at both ends of the fixed hook seat 4 through the first U-shaped opening 102, and the second flip hinge 2 can be flipped and supported on the fixed hook seat 4 through the flip latch 3, and the second U-shaped opening 201 of the second flip hinge 2 is aligned with the first U-shaped opening 102 of the first flip hinge 1, and the upper end of the fixed hook seat 4 can pass through, see Figure 1 and Figure 2 When the second flip hinge 2 is separated from the fixed hook seat 4, the first flip hinge 1 can pass through the entire fixed hook seat 4 with the second flip hinge 2 and the flip latch 3 through the first U-shaped opening 102 opened thereon and separate from the fixed hook seat 4, see Figure 4 .

[0032] Specifically, as a specific embodiment of the present utility model: a locking slot 301 is provided on the flip latch 3 , and the flip latch 3 is fixed together with the second flip hinge 2 through the locking slot 301 .

[0033] The utility model provides a multi-purpose hinge structure for a flatbed truck, which includes the following four usage states:

[0034] The first use state is the locked state, such as Figure 1 As shown, in this state, the carriage guardrail 6 used in conjunction with it will be in a locked state, see Figure 6 As shown;

[0035] The second usage state is the flip-down state, such as Figure 2 As shown, in this state, the carriage guardrail 6 used in conjunction with it will be in a downward flipped state, see Figure 7 As shown;

[0036] The third usage state is unlocked state, such as Figure 3 As shown, in this state, the carriage guardrail 6 used in conjunction with it will be in an unlocked state, see Figure 8 As shown;

[0037] The fourth use state is the flip-up state, such as Figure 4 As shown, in this state, the carriage guardrail 6 used in conjunction with it will be in an upward flip state, see Fig. 9 shown.

[0038] Finally, it should be noted that the above description is only an embodiment of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made using the contents of the present utility model specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present utility model.
