[0023] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.
[0024] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.
[0025] See also Figure 1-3 The present application discloses a blocking mechanism, including a blocking plate 3 arranged on a mounting seat 1, one end of the blocking plate 3 is connected to a telescopic structure 5 and a reset member 4, and the other ends of the telescopic structure 5 and the reset member 4 are fixed on the mounting seat. The telescopic structure 5 drives the blocking plate 3 to release the blocking state under the action of an external force, and when the external force is removed, the reset member 4 drives the blocking plate 3 to restore the blocking state.
[0026] The blocking mechanism provided in the present application can be installed on or at the end of a conveyor line for flipping. In the present application, the blocking mechanism is described as being installed at the end of a conveyor line.
[0027] The conveyor line is used to transport items. At the end of the conveyor line, there may be a situation where the conveyor line turns or there is no need to unload goods temporarily. In order to prevent the goods from falling in this situation, a blocking plate needs to be set to block the goods. The blocking can be removed when unloading is required. The goods unloaded from the conveyor line are generally transported by an AGV (Automated Guided Vehicle) trolley. At this time, the AGV trolley needs to be close to the edge of the conveyor line. The blocking mechanism of the present application is set at the edge of the conveyor line. When the AGV trolley approaches, it will squeeze the telescopic mechanism 5. Under the squeezing of external force, the telescopic mechanism 5 will expand, drive the blocking plate 3 to move, and release the blocking state. At this time, the goods can be moved down the conveyor line under the rotation of the roller. When the AGV trolley leaves, the external force disappears, and the blocking plate 3 returns to the blocking state under the action of the reset member 4.
[0028] In the present application, the reset member 4 can be a device with elastic properties such as a spring or a leaf spring, as long as its elastic force can meet the elastic force requirements in the actual application scenario, and there is no specific limitation in the present application.
[0029] The present application provides two telescopic structures, which are described below respectively. Embodiment 1
[0030] A blocking mechanism comprises a blocking plate 3 arranged on a mounting seat 1, one end of the blocking plate 3 is connected to a telescopic structure 5 and a reset member 4, the other ends of the telescopic structure 5 and the reset member 4 are fixed to the mounting seat, the telescopic structure 5 drives the blocking plate 3 to release the blocking state under the action of an external force, and when the external force is removed, the reset member 4 drives the blocking plate 3 to restore the blocking state.
[0031] The telescopic structure 5 is a telescopic arm, which includes a first rotating shaft 51, a second rotating shaft 53 and a third rotating shaft 54. The first rotating shaft 51 is fixed on the mounting base 1, and the third rotating shaft 54 is fixedly connected to one end of the blocking plate 3. The second rotating shaft 53 is hinged to the second rotating shaft 53 and the third rotating shaft 54 respectively through a connecting plate 52.
[0032] In embodiment 1, the telescopic mechanism 5 is a telescopic arm, the first rotating shaft 51 is fixedly arranged on the mounting base 1, the third rotating shaft 54 is connected to one end of the blocking plate 3, and the other end of the blocking plate 3 is not connected to any structure. A second rotating shaft 53 is arranged between the first rotating shaft 51 and the third rotating shaft 54, and the second rotating shaft 53 is hinged through a connecting plate 52. In order to keep the second rotating shaft 53 in a protruding state, the distance between the first rotating shaft 51 and the third rotating shaft 54 is less than the length of the two connecting plates 52. Therefore, when the reset member 4 remains contracted, it will drive the third rotating shaft 54 to move upward. Since the first rotating shaft 51 is fixed differently and the connecting plate 52 has a certain rigidity, the second rotating shaft 53 protrudes outward. When the AGV trolley is squeezed, the second rotating shaft 53 first contacts the AGV trolley, and the second rotating shaft 53 approaches the mounting seat 1 under the action of external force. Since the connecting plate 52 is hinged on the second rotating shaft 53, the connecting plate 52 rotates around the second rotating shaft 53 at this time. The connecting plate 52 between the first rotating shaft 51 and the second rotating shaft 53 pushes the second rotating shaft 53 to move downward, and further pushes the connecting plate 52 between the second rotating shaft 53 and the third rotating shaft 54. Since the third rotating shaft 54 is connected to the blocking plate 3, and the blocking plate 3 is a non-fixed structure, the third rotating shaft 54 can move downward, driving the blocking plate 3 to move, thereby realizing a blocking state structure. Embodiment 2
[0033] A blocking mechanism comprises a blocking plate 3 arranged on a mounting seat 1, one end of the blocking plate 3 is connected to a telescopic structure 5 and a reset member 4, the other ends of the telescopic structure 5 and the reset member 4 are fixed to the mounting seat, the telescopic structure 5 drives the blocking plate 3 to release the blocking state under the action of an external force, and when the external force is removed, the reset member 4 drives the blocking plate 3 to restore the blocking state.
[0034] The telescopic structure 5 includes a compression plate 55 , on which a magnet 56 and an elastic member 57 are disposed. The magnet 56 is used to absorb the blocking plate 3 to release the blocking state.
[0035] In the second embodiment, the telescopic structure 5 is implemented by a compression plate 55. The compression plate 55 is arranged perpendicular to the mounting seat 1 and protrudes from the mounting seat 1. An elastic member 57 is arranged between the compression plate 55 and the mounting seat 1. After the compression plate 55 is squeezed by the AGV trolley, the compression state of the compression plate 55 can be maintained due to the existence of external force. When the AGV trolley leaves, the external force disappears, and the compression plate 55 is reset under the elastic force of the elastic member 57. In order to prevent the compression plate 55 from falling out during the resetting process, the present application can set a limiting structure on the displacement path of the compression plate 55, or fix the elastic member 57 between the compression plate 55 and the mounting seat, and control the situation of the compression plate 55 falling out by the elastic member 57.
[0036] A magnet 56 is provided on one side of the compression plate 55 close to the blocking plate 3. When the compression plate 55 is compressed, the magnet 56 approaches the blocking plate 3, and the blocking plate 3 is adsorbed and moved downward under the suction force of the magnet 56, thereby contacting the blocking state. In order to achieve the adsorption of the blocking plate 3, a metal sheet can be provided on the side of the blocking plate 3 close to the compression plate 55, or the blocking plate 3 is made of metal material, or metal powder is added to the manufacturing material of the blocking plate 3. Other technical solutions that can make the blocking plate 3 adsorbed by the magnet belong to the protection scope of this application and will not be repeated here.
[0037] In order to ensure that the compression plate 55 can automatically reset after the external force acting on the compression plate 55 disappears, the magnetic force between the magnet 56 and the blocking plate 3 needs to be smaller than the elastic force of the elastic member 57. When the compression plate 55 is squeezed, the external force is used on the compression plate 55 to keep the elastic member 58 in a compressed state. After the external force disappears, the elastic member 57 stretches to push the compression plate 55 to reset. However, at this time, there is a magnetic force between the compression plate 55 and the blocking plate 3. In order to overcome the magnetic force and realize the reset of the compression plate 55, the elastic force of the elastic member 57 must be greater than the magnetic force between the magnet 56 and the blocking plate 3.
[0038] In order to facilitate the limiting of the blocking plate 3 , the embodiment of the present application further includes a limiting member 2 fixed on the mounting seat 1 , and the blocking plate 3 is arranged on the mounting seat 1 through the limiting member 2 .
[0039] Similarly, the present application provides a variety of implementations of the limiting member 2, which are described below respectively. Embodiment 3

[0041] The limiting member 2 is provided with a cavity inside, the blocking plate 3 passes through the cavity, and one end of the blocking plate 3 extending out of the cavity is connected to the telescopic structure 5 and the reset member 4 .
[0042] In Example 3, the limiting member 3 is a cavity arranged on the mounting seat 1, and the cavity passes through the mounting seat 1. The blocking plate 3 is arranged in the cavity, and both ends extend out of the cavity. One end is used to block the goods on the conveyor line, and the other end fixes the telescopic structure 5 and the reset member 4. Embodiment 4
[0043] A blocking mechanism comprises a blocking plate 3 arranged on a mounting seat 1, one end of the blocking plate 3 is connected to a telescopic structure 5 and a reset member 4, the other ends of the telescopic structure 5 and the reset member 4 are fixed to the mounting seat, the telescopic structure 5 drives the blocking plate 3 to release the blocking state under the action of an external force, and when the external force is removed, the reset member 4 drives the blocking plate 3 to restore the blocking state.
[0044] The limiting member 2 is a groove formed on the mounting seat 1 , and the blocking plate 3 is disposed in the groove.
[0045] In embodiment 4, the limiting member 2 is a groove opened on the mounting seat 1, the groove passes through the mounting seat 1, and the blocking plate 3 is arranged in the groove. The groove can be realized by hollowing out a part of the area on the mounting seat 1, or it can be two elongated limiting blocks arranged on the mounting seat 1, and the groove is formed by the opposite sides of the limiting blocks to slide in it with the blocking plate 3. Embodiment 5

[0047] The limiting members 2 are protrusions disposed on both sides of the blocking plate 3 and fixed on the mounting seat 1 .
[0048] In the fifth embodiment, the position-limiting member 2 is a protrusion provided on the mounting seat 1, the height of the protrusion is greater than the thickness of the blocking plate 3, and is provided on both sides of the blocking plate 3. Since the blocking plate 3 is movable in the longitudinal direction, the protrusion only needs to limit the lateral movement direction of the blocking plate 3. According to the specific application scenario, the number of protrusions provided on each side of the blocking plate can be adjusted, but at least one protrusion is provided on each side of the blocking plate 3. Other technical solutions that can limit the blocking plate 3 and are not mentioned in this application also belong to the protection scope of this application and are not listed one by one here.
[0049] In the present application, in an embodiment in which a limiting member 2 is provided, one end of the telescopic structure 5 is fixedly connected to the blocking plate 3 , and the other end is fixed to the limiting member 2 .
