[0013] A spring is sleeved on the outside of the driving rod, and two ends of the spring are respectively abutted against the first plate frame and the second plate frame;

[0014] The flip conveyor belt has a vertical state and a horizontal state. During the process of switching from the vertical state to the horizontal state, the driving rod drives the second plate frame to approach the first plate frame, and the spring is compressed.

[0015] Several optional methods are also provided below, but they are not intended to be additional limitations on the above-mentioned overall solution, but are merely further supplements or preferences. Under the premise that there are no technical or logical contradictions, each optional method can be combined with the above-mentioned overall solution separately, and multiple optional methods can also be combined.

[0016] Preferably, in a vertical state, the bottom side of the connecting block abuts against the mounting plate, and in a horizontal state, the side of the connecting block away from the conveyor belt abuts against the mounting plate.

[0019] A nut is screwed onto the screw rod, and the nut abuts against a side of the first plate frame away from the second plate frame.

[0020] Preferably, the extending direction of the conveyor belt is set as the length direction, and a plurality of the driving rods are arranged in a single row at intervals along the length direction.

[0021] Preferably, two adapter seats and two connecting blocks are provided, the shaft rod is fixed between the two connecting blocks, the two adapter seats are located between the two connecting blocks, and a rotating rod for the end of the driving rod to be transferred is provided between the two adapter seats.

[0022] Preferably, the distance between the shaft rod and the mounting plate is smaller than the distance between the rotating rod and the mounting plate.

[0023] Preferably, two torsion springs are installed on the shaft, and the torsion springs are located between the adapter and the connecting block.

[0024] Preferably, there are two auxiliary driving devices, and the two auxiliary driving devices are respectively installed on both sides of the conveyor belt along its extension direction, and the two auxiliary driving devices are spring driving devices.

[0028] Compared with the prior art, the utility model has the following beneficial effects:

[0029] A flip conveyor belt is installed above the stairs in the basement. When there is no need to transport goods, the flip conveyor belt is in a vertical state and against the wall, which will not affect the normal use of the stairs. When goods need to be transported, the conveyor belt can be manually flipped to a flat state. Since the connecting block is fixed between the shaft rod and the conveyor belt, one end of the driving rod is transferred to the transfer seat, and the other end is fixed to the second plate frame. In this process, when the power for flipping the conveyor belt is given, the shaft rod can rotate on the transfer seat in combination with the gravity of the conveyor belt itself, and one end of the driving rod can rotate around the transfer seat. The distance between the side of the conveyor belt and the transfer seat (specifically the transfer position of the transfer seat and the driving rod) is reduced, so that the other end of the driving rod drives the second plate frame, and one end of the mounting rod passes through the through hole, and the spring is compressed. When the conveyor belt needs to be flipped back to the vertical position, the pressure given by the spring to the adapter (the elastic energy released by the spring) will help reduce the force required for flipping, making flipping easier. When the spring recovers its deformation, the conveyor belt flips to the vertical position. The design of a flip conveyor belt can effectively replace manual handling, save time and effort, is easy to use, and is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Specific implementation plan: see Figure 1-Figure 7 The utility model is a turnover conveyor belt suitable for installation in a basement, which is installed above the stairs in the basement. The turnover conveyor belt 1 includes:

[0044] Conveyor belt 1;

[0045] At least two mounting plates 2 are spaced apart from each other along the extension direction of the stairs and are fixed to one side of the stairs through a fixing frame 7. At least one adapter seat 3 is fixed on the mounting plate 2, and a shaft rod 4 is connected to the adapter seat 3. At least one connecting block 5 is fixed between the outer frame of the conveyor belt 1 and the shaft rod 4.

[0046] At least two auxiliary driving devices are installed inside the conveyor belt 1, and at least one of the two auxiliary driving devices is a spring 65 driving device 6, and the spring 65 driving device 6 includes:

[0047] A fixed component, fixed inside the conveyor belt 1;

[0048] A first plate frame 62 is fixed on the fixing assembly, and a plurality of through holes spaced apart from each other are provided on the first plate frame 62;

[0049] A plurality of mutually spaced mounting rods 64, one end of which passes through the through hole and the other end of which is fixed on the second plate frame 63;

[0050] A driving rod 67, one end of which is fixed to the second plate frame 63, and the other end of which is connected to the connecting seat 3;

[0051] The spring 65 is sleeved on the outside of the driving rod 67, and the two ends of the spring 65 are respectively abutted on the first plate frame 62 and the second plate frame 63;

[0052] The flip conveyor belt 1 has a vertical state and a horizontal state. During the process of switching from the vertical state to the horizontal state, the driving rod 67 drives the second plate frame 63 to approach the first plate frame 62, and the spring 65 is compressed.

[0053] The following is an explanation of the working principle of how the spring 65 driving device 6 in this application specifically assists in driving and realizing the overturning of the conveyor belt 1:

[0054] See also Figure 5 and Figure 6It can be seen that in the vertical state, the spring 65 is in an uncompressed state, and the transfer position of the driving rod 67 and the transfer seat 3 is set to the transfer position, and the distance between the side of the conveyor belt 1 and the transfer position is the largest. In the vertical state, since the conveyor belt 1 is arranged on one side of the stairs, people can walk on the stairs normally. When it is necessary to transport goods, the flip conveyor belt 1 needs to be switched to a flat state. Since the connecting block 5 is fixed between the shaft rod 4 and the conveyor belt 1, one end of the driving rod 67 is transferred to the transfer seat 3, and the other end is fixed to the second plate frame 63. The conveyor belt 1 is flipped by hand, and the gravity of the conveyor belt 1 itself is cooperated to make the shaft rod 4 rotate on the transfer seat 3, and one end of the driving rod 67 rotates around the transfer seat 3. At this time, the distance between the side of the conveyor belt 1 and the transfer position gradually decreases, so that the other end of the driving rod 67 drives the second plate frame 63, and makes one end of the mounting rod 64 pass through the through hole, the spring 65 is compressed, and all the springs 65 accumulate elastic energy together.

[0055] When the flip conveyor belt 1 is in a flat state, one end of the driving rod 67 extends into the conveyor belt 1, the distance between the side of the conveyor belt 1 and the transfer position is the smallest, and the spring 65 is compressed to the maximum extent. When the flip conveyor belt 1 needs to be switched back to the vertical state, the conveyor belt 1 is manually flipped. When the conveyor belt 1 is slightly flipped, the elastic energy accumulated by the spring 65 due to compression will begin to be released, thereby assisting the conveyor belt 1 to flip. Flipping does not require very large force and is relatively easy (note that in the flat state, the pressure given by the spring 65 to the transfer seat 3 largely offsets the gravity of the conveyor belt 1. Therefore, the conveyor belt 1 can be flipped without very large force). When the flip conveyor belt 1 is switched to the vertical state, the spring 65 is in an uncompressed state and the elastic energy is completely released.

[0056] Here, the elastic energy stored in the springs 65 in the flat state can be increased by increasing the number of the springs 65, thereby making the conveyor belt 1 easier to flip.

[0057] As a preferred implementation manner of this embodiment, in the vertical state, the bottom side of the connecting block 5 abuts against the mounting plate 2, thereby maintaining the vertical position of the conveyor belt 1; in the horizontal state, the side of the connecting block 5 away from the conveyor belt 1 abuts against the mounting plate 2, thereby maintaining the horizontal position of the conveyor belt 1.

[0058] Then, see Figure 5 and Figure 6 It can be seen that in this embodiment, the fixing component includes:

[0059] At least two screw rods 61 are fixed inside the conveyor belt 1, and a first plate frame 62 is provided with slots for the screw rods 61 to pass through;

[0060] The nut 66 is screwed onto the screw rod 61 , and the nut 66 abuts against a side of the first plate frame 62 away from the second plate frame 63 .

[0061] In this embodiment, due to the elastic force of the spring 65, the first plate frame 62 is kept in contact with the nut 66. Therefore, when the position of the first plate frame 62 needs to be adjusted, it can be achieved by adjusting the position of the nut 66 on the screw rod 61. Since the spring 65 is located between the first plate frame 62 and the second plate frame 63, after the position of the first plate frame 62 is adjusted, the tension state of the spring 65 will also be adjusted accordingly.

[0062] Then, in this embodiment, the extending direction of the conveyor belt 1 is set as the length direction, and a plurality of driving rods 67 are arranged in a single row at intervals along the length direction.

[0063] In addition, in this embodiment, there are two adapter seats 3 and two connecting blocks 5, the shaft rod 4 is fixed between the two connecting blocks 5, the two adapter seats 3 are located between the two connecting blocks 5, and a rotating rod for the end of the driving rod 67 to be transferred is provided between the two adapter seats 3.

[0064] See also Figure 6 In order to make the pressure applied by the spring 65 to the adapter 3 act to offset the gravity of the conveyor belt 1, in this embodiment, the distance between the shaft rod 4 and the mounting plate 2 is smaller than the distance between the rotating rod and the mounting plate 2.

[0065] Then, in this embodiment, two torsion springs 8 are installed on the shaft rod 4 , and the torsion springs 8 are located between the adapter seat 3 and the connecting block 5 .

[0066] Here, the setting of the torsion spring 8 can be used to cooperate in realizing the flipping of the conveyor belt 1. During the process of the flip conveyor belt 1 switching from the upright state to the horizontal state, the torsion spring 8 accumulates torque. During the process of the flip conveyor belt 1 switching from the horizontal state to the upright state, the torque released by the torsion spring 8 can cooperate to reduce the force required for flipping.

[0067] See also Figure 4 When it is necessary to manually drive the conveyor belt 1 to flip, two auxiliary driving devices can be optionally set up, and the two auxiliary driving devices are respectively installed on both sides of the conveyor belt 1 along its own extension direction, and the two auxiliary driving devices are spring 65 driving devices 6.

[0068] More specifically, when it is necessary to automatically drive the conveyor belt 1 to flip, two drive auxiliary devices can be set, and one of the drive auxiliary devices is an electric push rod 92192 device, and the other drive auxiliary device is a spring 65 drive device 6, and the electric push rod 92192 device includes:

[0069] A fixed bracket 91 is fixed inside the conveyor belt 1;

[0070] The electric push rod 92192 is fixed on the fixed bracket 91. One end of the push rod 921 of the electric push rod 92192 passes through the outer frame of the conveyor belt 1 and is transferred to the transfer seat 3.

[0071] Here, when it is necessary to switch between the horizontal state and the vertical state, the electric push rod 92192 can be controlled by the remote control. When it is necessary to switch to the horizontal state, the push rod 921 of the electric push rod 92192 is controlled to retract. During this process, the gravity of the conveyor belt 1 causes the drive rod 67 on the spring 65 drive device 6 to drive the second plate frame 63 inward, and the spring 65 accumulates elastic energy (see above for the principle). When it is necessary to switch to the vertical state, the push rod 921 of the electric push rod 92192 is controlled to extend. During this process, the spring 65 on the spring 65 drive device 6 releases elastic energy, and cooperates with the thrust of the push rod 921 to complete the switching of the flip conveyor belt 1 to the vertical state.

[0072] Note that the above-mentioned electric push rod 92192 is equivalent to replacing the external force given by manpower during the manual driving process, thereby realizing the electric control of the conveyor belt 1 flipping.

[0073] The above description of a turnover conveyor belt suitable for installation in a basement of the utility model is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the inventive concept of the utility model, or direct / indirect application in other related technical fields are included in the patent protection scope of the utility model.
