It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0021] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model may be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0022] Embodiment 1: As Figures 1-4As shown in the figure, the utility model provides an anti-retreat self-locking horizontal stopper, which includes: a bottom plate 1, a mounting block 2 is fixedly connected to the top of the bottom plate 1, a cylinder 3 is fixedly connected to the rear surface of the mounting block 2, and a moving block 4 is fixedly connected to the telescopic end of the cylinder 3; a blocking assembly 9, the blocking assembly 9 is arranged on the top of the bottom plate 1, the blocking assembly 9 includes a first blocking member 901 and a second blocking member 902, a first fixing block 903 is fixedly connected between the first blocking member 901 and the second blocking member 902, a hydraulic buffer 905 is fixedly connected to the rear surface of the first fixing block 903, a connecting rod 914 is fixedly connected to the telescopic end of the hydraulic buffer 905, a blocking block 906 is rotatably connected to the outer surface of the connecting rod 914, a fourth fixing shaft 910 is fixedly connected between the inner walls of the blocking block 906, the fourth fixing shaft 910 is rotatably connected to the first blocking member 901 and the second blocking member 902, a hanging tooth 909 is fixedly connected to the outer surface of the fourth fixing shaft 910 close to the blocking block 906, a fixing rod 913 is fixedly connected to the outer surface of the second blocking member 902, a hook 911 is rotatably connected to the outer surface of the fixing rod 913, a torsion spring 912 is arranged on the outer surface of the hook 911, the torsion spring 912 is fixedly connected to the outer surface of the second blocking member 902, a first fixing shaft 5 is fixedly connected between the inner walls of the moving block 4, a first moving wheel 6 is rotatably connected to the outer surface of the first fixing shaft 5, second moving wheels 7 are symmetrically and rotatably connected to the outer surface of the first fixing shaft 5 near both sides, a rotating shaft 915 is fixedly connected between the first blocking member 901 and the second blocking member 902, the outer surface of the rotating shaft 915 is rotatably connected to the inner surface of the mounting block 2, a second fixing block 904 is fixedly connected between the first blocking member 901 and the second blocking member 902, the connecting rod 914 slidably penetrates through the second fixing block 904, a spring 916 is fixedly connected between the connecting rod 914 and the first fixing block 903, and the telescopic end of the hydraulic buffer 905 slidably penetrates through the outer surface of the first fixing block 903.

[0023] The effect achieved by the entire Embodiment 1 is that when the anti-retreat self-locking horizontal stopper is in use, it is fixedly installed on the product assembly line through the mounting block 2. The air cylinder 3 is started, and its telescopic end extends forward, pushing the moving block 4 forward. When the two second moving wheels 7 rotate synchronously on the outer surface of the first fixed shaft 5, they will gradually come into contact with the surfaces of the first stopper 901 and the second stopper 902 during the movement on the top of the bottom plate 1. When the air cylinder 3 reaches its maximum extension distance, the first stopper 901 and the second stopper 902 will be lifted, causing the rotating shaft 915 to rotate synchronously in the inner wall of the mounting block 2, so that the stopper 906 will be lifted upward. A fixed rod 913 is fixedly connected to the inner side of the second stopper 902, and a hook 911 is rotatably connected to its surface. A torsion spring 912 is arranged between the hook 911 and the second stopper 902. When the stopper 906 is impacted by the goods, the stopper 906 will rotate around the fourth fixed shaft 910, and the impact surface of the stopper 906 is perpendicular to the goods. The impact force received by the stopper 906 will be transmitted to the hydraulic buffer 905 and the spring 916 through the connecting rod 914. Under the combined action of the spring 916 and the hydraulic buffer 905, a buffering effect is achieved. At the same time, the hanging teeth 909 fixed on the surface of the fourth fixed shaft 910 will rotate synchronously and slide friction with the surface of the hook 911 until the goods push the stopper 906 to the vertical stop position. At this time, the positions of the hook 911 and the hanging teeth 909 are opposite, and the hook 911 will hook the card slot on the surface of the hanging teeth 909, playing a role of self-locking. When the telescopic end of the air cylinder 3 contracts, when the moving block 4 moves backward and resets, the moving block 4 will slide friction with the surface of the hook 911 during the movement, forcing it to rotate around the fixed rod 913, deforming the torsion spring 912, and separating the position where the hook 911 and the hanging teeth 909 are hooked, facilitating the downward reset of the stopper 906 to allow the goods to pass.

[0024] Embodiment 2: As Figures 1-4 shown, the first moving wheel 6 is located inside the moving block 4. A slide rail 8 is fixedly connected to the top of the bottom plate 1, and the slide rail 8 is provided in a matching manner with the first moving wheel 6. A third fixed shaft 907 is fixedly connected to the inner surface of the stopper 906, and blocking wheels 908 are symmetrically rotatably connected to the outer surface of the third fixed shaft 907.

[0025] The effect achieved by the entire Embodiment 2 is that when the goods are released, by fixedly connecting the third fixed shaft 907 to the inner surface of the stopper 906, the blocking wheels 908 symmetrically rotatably connected to its surface will roll friction with the bottom of the goods when the goods pass, facilitating the passage of the goods. By fixedly connecting the slide rail 8 to the top of the bottom plate 1, when the moving block 4 moves forward, the first moving wheel 6 will roll synchronously along the outer surface of the slide rail 8, playing a role of limiting and preventing its position from deviating during movement, with high practicality.

[0026] Working principle: When the anti-retreat self-locking horizontal stopper is in use, it is fixedly installed on the product assembly line through the mounting block 2. The air cylinder 3 is started, and its telescopic end extends forward, pushing the moving block 4 forward. When the two second moving wheels 7 rotate synchronously on the outer surface of the first fixed shaft 5, they will gradually come into contact with the surfaces of the first stopper 901 and the second stopper 902 during the movement on the top of the bottom plate 1. When the air cylinder 3 reaches its maximum extension distance, the first stopper 901 and the second stopper 902 will be lifted, causing the rotating shaft 915 to rotate synchronously in the inner wall of the mounting block 2, and the stopper 906 will be lifted upward. A fixed rod 913 is fixedly connected to the inner side of the second stopper 902, and a hook 911 is rotatably connected to its surface. A torsion spring 912 is arranged between the hook 911 and the second stopper 902. When the stopper 906 is impacted by the goods, the stopper 906 will rotate around the fourth fixed shaft 910, and the impact surface of the stopper 906 is perpendicular to the goods. The impact force received by the stopper 906 will be transmitted to the hydraulic buffer 905 and the spring 916 through the connecting rod 914. Under the combined action of the spring 916 and the hydraulic buffer 905, a buffering effect is achieved. At the same time, the hanging teeth 909 fixed on the surface of the fourth fixed shaft 910 will rotate synchronously and slide friction with the surface of the hook 911 until the goods push the stopper 906 to the vertical stop position. At this time, the positions of the hook 911 and the hanging teeth 909 are opposite, and the hook 911 will hook the card slot on the surface of the hanging teeth 909, playing a self-locking role. When the telescopic end of the air cylinder 3 contracts, the moving block 4 will move backward and reset. During the movement, the moving block 4 will slide friction with the surface of the hook 911, forcing it to rotate around the fixed rod 913, deforming the torsion spring 912, and separating the position where the hook 911 and the hanging teeth 909 are hooked, facilitating the downward movement and reset of the stopper 906 to allow the goods to pass. When the goods are released, by fixedly connecting the third fixed shaft 907 to the inner surface of the stopper 906, the blocking wheels 908 symmetrically rotatably connected to its surface will roll friction with the bottom of the goods when the goods pass, facilitating the passage of the goods. By fixedly connecting the slide rail 8 to the top of the bottom plate 1, when the moving block 4 moves forward, the first moving wheel 6 will roll synchronously along the outer surface of the slide rail 8, playing a limiting role to prevent its position from deviating during movement, and it has high practicability.

Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
