[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] As Figures 1 to 5 shown, the present invention provides a high-strength road buffer belt with a compressive structure, including a buffer belt installation bottom shell 1, a buffer belt top shell 2 is movably installed on the top of the buffer belt installation bottom shell 1, installation nails 3 are arranged at the front and rear of both sides of the top of the buffer belt top shell 2, a fixed plate 4 is arranged in the middle of the top end of the buffer belt installation bottom shell 1, a first buffer assembly 5 is movably installed between the inner walls of the fixed plate 4, a ventilation assembly 6 is arranged outside the first buffer assembly 5 between the fixed plate 4 and the buffer belt top shell 2; a second buffer assembly 7 is arranged between both sides of the fixed plate 4 and the inner wall of the buffer belt top shell 2;

[0024] The first buffer assembly 5 includes a pneumatic buffer cavity 501, the pneumatic buffer cavity 501 is opened in the middle of the fixed plate 4, a first movable rod 502 is movably installed on the inner wall of the pneumatic buffer cavity 501, a first buffer top plate 503 is movably installed on the top of the first movable rod 502. By the downward movement of the first buffer top plate 503 and the first movable rod 502, the gas at the bottom of the inner cavity of the pneumatic buffer cavity 501 can be compressed.

[0025] By the downward movement of the first movable rod 502, the inner cavity space at the upper end of the pneumatic buffer cavity 501 will become larger and generate negative pressure. Thus, the outside gas can be introduced through the telescopic ventilation connecting pipe 601 and the one-way ventilation valve flap 602, so that the inner cavity at the top of the pneumatic buffer cavity 501 is filled with the corresponding gas, and the first movable rod 502 can be smoothly lowered.

[0026] As Figure 2 and Figure 3 shown, the number of the first movable rods 502 is four, and the sizes of the four first movable rods 502 are the same.

[0027] With the above solution, when the top of the buffer belt top shell 2 is squeezed, the first buffer top plate 503 will be squeezed to push the four first movable rods 502 to descend smoothly, and the movement of the first buffer top plate 503 is limited.

[0028] As Figure 3 shown, the ventilation assembly 6 includes a telescopic ventilation connecting pipe 601 and a one-way ventilation valve flap 602;

[0029] The telescopic ventilation connecting pipe 601 is fixedly connected to the top of the fixed plate 4 and the outside of the top of the pneumatic buffer chamber 501, and the one-way ventilation valve flap 602 is arranged on the inner wall of the top of the buffer belt top shell 2 and directly above the telescopic ventilation connecting pipe 601.

[0030] With the above solution, by setting the one-way ventilation valve flap 602, when the inner cavity space of the top of the pneumatic buffer chamber 501 slowly becomes larger, a negative pressure will be generated, and then the outside air can push the one-way ventilation valve flap 602 to flip and enter the inner cavity of the top of the pneumatic buffer chamber 501 through the telescopic ventilation connecting pipe 601 for replenishment, keeping the first movable rod 502 and the first buffer top plate 503 descending smoothly.

[0031] As Figure 3 shown, the number of the telescopic ventilation connecting pipes 601 is eight, and the eight telescopic ventilation connecting pipes 601 have the same size.

[0032] With the above solution, through the telescopic design of the telescopic ventilation connecting pipe 601 itself, when the top of the buffer belt top shell 2 moves downward under pressure, the telescopic ventilation connecting pipe 601 will be telescoped to maintain the connection effect with the pneumatic buffer chamber 501.

[0033] As Figure 4 and Figure 5 shown, the second buffer assembly 7 includes a buffer piston cylinder 701, a second movable rod 702, a second buffer top plate 703 and an auxiliary return spring 704;

[0034] The buffer piston cylinder 701 is fixedly installed on the outside of the fixed plate 4, the second movable rod 702 is movably installed in the inner cavity of the buffer piston cylinder 701, the second buffer top plate 703 is fixedly installed on the outside of the second movable rod 702, and the auxiliary return spring 704 is fixedly installed on the inner side of the second buffer top plate 703.

[0035] With the above solution, by setting the second buffer top plate 703, through the inclined surface design of the top of the second buffer top plate 703, when the inclined surface on one side of the buffer belt top shell 2 is pressed, the inclined surface of the second buffer top plate 703 will be pushed, so that it will move in the opposite direction to the second movable rod 702 smoothly.

[0036] AsFigure 4 and Figure 5 As shown, the inner end of the auxiliary reset spring 704 is fixedly connected to the outer end of the fixed plate 4.

[0037] With the above solution, by providing the auxiliary reset spring 704, when the second buffer top plate 703 and the second movable rod 702 move towards each other, the second movable rod 702 can squeeze the auxiliary reset spring 704 and the cavity at the inner end of the buffer piston air cylinder 701 for compression, thereby buffering and damping the pressure received by the inclined surface of the buffer belt top shell 2. When the pressure is released, the elastic force of the auxiliary reset spring 704 and the air pressure in the inner cavity of the buffer piston air cylinder 701 will be released, thereby pushing the two second movable rods 702 and the second buffer top plate 703 to reset stably.

[0038] As Figure 5 shown, a metal sealing ring 8 is provided between the inner side of the buffer piston air cylinder 701 and the outer side of the fixed plate 4.

[0039] With the above solution, through the design of the metal sealing ring 8, a good sealing effect can be achieved at the position where the buffer piston air cylinder 701 is installed and connected to the fixed plate 4, avoiding the reduction of gas escape from the inner side of the buffer piston air cylinder 701 and affecting the subsequent reset of the second movable rod 702 and the second buffer top plate 703.

[0040] The working principle and usage process of the present utility model:

[0041] First, when the driver drives the vehicle through the top of the buffer belt top shell 2, it will pre-squeeze and push the second buffer top plate 703 and the second movable rod 702 towards each other. Then, the pressure generated by the gas in the inner cavity of the buffer piston air cylinder 701 and the auxiliary reset spring 704 can be used for buffering. Then, it will squeeze the top of the buffer belt top shell 2 and push the first buffer top plate 503 and the first movable rod 502 to move downward. Finally, the gas at the bottom of the inner cavity of the pneumatic buffer cavity 501 can buffer the pressure generated at the top of the buffer belt top shell 2, greatly reducing the pressure when the vehicle passes through and reducing the vibration sensation at the same time.

[0042] Then, when the vehicle passes through, due to the cooperation of the gas at the inner end of the inner cavity of the buffer piston air cylinder 701 and the auxiliary reset spring 704, the second movable rod 702 and the second buffer top plate 703 can be pushed to move and reset. At the same time, the gas at the bottom of the inner cavity of the pneumatic buffer cavity 501 will recover after being compressed, thereby pushing the first movable rod 502 and the first buffer top plate 503 upward to push the gas at the bottom of the inner cavity of the pneumatic buffer cavity 501 out of the outside through the telescopic ventilation connecting pipe 601 and the one-way ventilation valve flap 602. Finally, the second buffer top plate 703 and the first buffer top plate 503 can be smoothly reset for subsequent buffer and damping treatment.
