As shown in fig. 1 and 10, the embodiment of the utility model provides an anti-derailment structure 10 is applied to the conveying line body 1, and anti-derailment structure 10 can play the effect that blocks or relieve and block to conveyor 40 on the conveying line body 1 to reduce the probability that conveyor 40 derailed on the conveying line body 1, make the conveying line body 1 have more stable transport environment.

As shown in fig. 1 and 10, derailing prevention structure 10 includes a base 11, a limiting component 12 and a control component 13, wherein base 11 is used for connecting with limiting component 12, and base 11 is connected with control component 13 for providing support for limiting component 12 and control component 13.

The limiting component 12 has a limiting rod 121, the limiting rod 121 is rotatably connected with the base 11, the limiting rod 121 can rotate a certain angle relative to the base 11, and the limiting rod 121 is used for blocking or unblocking the conveying device 40 on the conveying line body 1; when the limiting rod 121 is located on the moving path of the conveying device 40 and the limiting rod 121 is not subjected to an external force and rotates relative to the base 11, the position where the limiting rod 121 is located is an initial position, which is a position where a part of the limiting rod 121 blocks the conveying device 40.

The control component 13 has a transmission component 131 and an abutting component 132, the abutting component 132 is connected with the transmission component 131, and is used for driving the transmission component 131 to displace when the abutting component 132 is acted by force to displace; the transmission member 131 is connected to the limiting rod 121, the displacement motion of the abutting part 132 drives the limiting rod 121 to rotate through the transmission member 131, and further, the limiting rod 121 rotates a certain angle relative to the base 11, and a part of the limiting rod 121 is away from the initial position to release the blocking effect on the conveying device 40.

As shown in fig. 1 to 3, the position-limiting assembly 12 has a buffer 122 for buffering when the conveying device 40 impacts the derailing prevention structure 10.

In some embodiments, the buffer 122 is made of an elastic material, such as rubber or elastic steel, and the elastic buffer 122 can perform a better buffering function. The buffer 122 absorbs impact energy by virtue of its own material properties that can achieve elastic deformation.

The limiting rod 121 has a first connecting portion 1211, and the buffer element 122 is fixedly connected to the first connecting portion 1211, such that the buffer element 122 is disposed on one side of the limiting rod 121. The limiting rod 121 further has a second connecting portion 1212 and a third connecting portion 1213, the second connecting portion 1212 is connected to the transmission member 131, so that the transmission member 131 can drive the limiting rod 121 to rotate; the third connecting portion 1213 is rotatably connected to the base 11, so that the stopper rod 121 can rotate relative to the base 11, the stopper rod 121 blocks or unblocks the conveying device 40, and the risk of derailing the conveying device 40 is reduced.

As shown in fig. 1 and 3, in some embodiments, the length direction a of the limiting rod 121 is a direction pointed by an arrow at a in the drawing, the first connecting portion 1211, the second connecting portion 1212, and the third connecting portion 1213 are sequentially arranged along the length direction a of the limiting rod 121, and the buffer 122, the transmission member 131, and the base 11 are sequentially connected to the limiting rod 121 in the length direction a of the limiting rod 121. Therefore, the limiting rod 121 is in the movement process of realizing blocking and unblocking: the movement of the transmission member 131 can drive the first connection portion 1211 and the second connection portion 1212 to rotate relative to the third connection portion 1213 by using the third connection portion 1213 as a fulcrum and the second connection portion 1212 as a power point; furthermore, the blocking and unblocking of the conveying device 40 by the limiting rod 121 can be controlled by controlling the movement of the transmission member 131; the first connection portion 1211 and the third connection portion 1213 are disposed on opposite sides of the limiting rod 121, such that the first connection portion 1211 and the third connection portion 1213 have a longer disposition length; it can be understood that the first connection portion 1211 and the second connection portion 1212 are disposed on the same side of the third connection portion 1213, so that the second connection portion 1212 can directly drive the first connection portion 1211 to rotate relative to the third connection portion 1213 under the driving of the transmission member 131, thereby making the rotation of the limiting rod 121 around the third connection portion 1213 more efficient; taking the displacement motion of the transmission member 131 as an example, since the first connection portion 1211 and the third connection portion 1213 have a longer setting length, a smaller displacement stroke of the transmission member 131 can drive a larger rotation stroke of the first connection portion 1211 relative to the third connection portion 1213, so that the rotation of the limiting rod 121 is more efficient.

In some embodiments, the first connection portion 1211, the third connection portion 1213 and the second connection portion 1212 are sequentially disposed along the length direction a of the limiting rod 121, and the first connection portion 1211 and the second connection portion 1212 are disposed on two opposite sides of the limiting rod 121. So that the buffer 122, the base 11, and the transmission member 131 are sequentially disposed along the length direction a of the stopper rod 121. That is, the third connecting portion 1213 is a fulcrum, the second connecting portion 1212 is a power point, the resistance is the self-gravity of the stopper rod 121 and the buffer 122, the direction of the gravity is vertically downward, the power point and the resistance point are on opposite sides of the fulcrum, and the direction of the power applied to the stopper rod 121 by the transmission member 131 is the same as the direction of the resistance. The first connecting portion 1211 and the second connecting portion 1212 are disposed on two opposite sides of the limiting rod 121, so that the buffer 122 and the transmission member 131 are located on two opposite sides of the limiting rod 121, when the conveying device 40 moves along the conveying line 1 to the derailing prevention structure 10 and the limiting rod 121 is located at an initial position, the conveying device 40 first impacts the buffer 122, and thus the derailing prevention structure 10 stops the conveying device 40, thereby reducing the possibility that the conveying device 40 derails and flies out of the conveying line 1, and reducing injuries and property losses to other people. The transmission member 131 is disposed at one side of the limiting rod 121 and opposite to the buffer 122, when the limiting rod 121 blocks and the buffer 122 is impacted by the conveying device 40, the transmission member 131 does not collide with the conveying device 40 in advance, meanwhile, the transmission member 131 needs to be connected with the abutting piece 132, the abutting piece 132 displaces or rotates under the action of external force, and then the transmission member 131 drives the limiting rod 121 to rotate relative to the base 11, so as to release the blocking effect.

The transmission member 131 is connected with the limiting rod 121, the displacement motion of the abutting part 132 drives the limiting rod to rotate through the transmission member 131, and then the transmission member 131 drives the limiting rod 121 to rotate by a certain angle when the abutting part 132 is displaced under the action of external force, so that the blocking of the conveying device is removed, and the normal motion of the conveying device 40 at the position is realized.

As shown in fig. 1 to 3, the position limiting assembly 12 includes a first position limiting member 123. The first limiting member 123 is disposed on the base 11 in a position-adjustable manner, and at least a portion of the first limiting member 123 is used for abutting against the limiting rod 121, and the abutting position of the first limiting member 123 and the limiting rod 121 is located between the first connecting portion 1211 and the third connecting portion 1213; that is, the abutting position of the first limiting member 123 is between the fulcrum of the limiting rod 121 and the buffering member 122, so as to provide a supporting force for the limiting rod 121; it can be understood that, since the third connection portion 1213 of the limiting rod 121 is rotatably connected to the base 11, the first connection portion 1211 as a free end rotates around the third connection portion 1213 under the action of its own gravity, and the first limiting member 123 abuts between the first connection portion 1211 and the third connection portion 1213, so as to ensure that the derailing prevention structure 10 has a stable blocking effect; when the transmission member 131 does not provide a force for rotating and supporting the limiting rod 121, the first stopper 123 prevents the limiting rod 121 from abutting against the conveyor line body 1. No matter the second connecting portion 1212 is disposed between the first connecting portion 1211 and the third connecting portion 1213, or the third connecting portion 1213 is disposed between the first connecting portion 1211 and the second connecting portion 1212, the first limiting member 123 can provide a supporting force for the limiting rod 121, so as to ensure that the derailment prevention structure 10 has a stable blocking effect.

Further, the abutting position between the first limiting member 123 and the limiting rod 121 can be changed by adjusting the position between the first limiting member 123 and the base 11, where the abutting position is the initial position of the limiting rod 121. When the limiting rod 121 is located at the initial position, the initial position of the limiting rod 121 is limited by the first limiting member 123, and when the limiting rod is not acted by an external force, in some embodiments, the first limiting member 123 is set to be a screw structure, the base 11 is provided with a thread matched with the base, the screw abuts against the limiting rod 12, and the initial position of the limiting rod 12 is changed by adjusting the locking position of the screw on the base 11. In other alternative embodiments, the connection manner of the first limiting member 123 and the base 11 may also be a snap connection, for example, two or more twist openings are arranged in the height direction of the base 11, a connection member is arranged on the first limiting member 123, the connection member can pass through the twist openings to enable the first limiting member 123 to be snap-connected to the base 11, and the abutting position of the first limiting member 123 and the limiting rod 121 is changed by adjusting the position at which the first limiting member 123 is snap-connected. The first limiting member 123 is connected to the base 11 in a clamping manner, and different clamping positions are adjusted to change the abutting positions of the first limiting member 123 and the limiting rod 121, so that the effect of adjusting the initial position of the limiting rod 121 is achieved.

The second limiting member 124 is disposed on the base 11 in a position-adjustable manner and is opposite to the first limiting member 123. The limiting device is used for limiting the rotation angle of the limiting rod 121 relative to the base 11, when the first limiting member 123 abuts against the limiting rod 121, the limiting rod 121 is located at an initial position, the limiting rod 121 achieves a blocking effect, and when the limiting rod 121 rotates under the action of external force, the limiting rod 121 is partially far away from the initial position; when the rotation amplitude of the limiting rod 121 is too large, the limiting rod 121 is difficult to automatically rotate back to the initial position, so that the blocking effect of the limiting rod 121 on the conveying device 40 is difficult to realize; in the embodiment, the second limiting member 124 is provided to limit the maximum rotation stroke of the limiting rod 121, so that the limiting rod 121 can still return to the initial position after rotating to the maximum rotation stroke, so as to block the conveying device 40.

In some embodiments, the second stopper 124 is a screw, and one end of the screw abuts against the stopper rod 121. The range in which the stopper rod 121 can rotate can be adjusted by adjusting the position of the set screw on the base 11. The first limiting member 123 and the second limiting member 124 are made of rigid materials, which are stable in structure and not easy to deform, and can reduce the loss caused by collision friction between the first limiting member 123 and the limiting rod 121, so that the limiting rod 121 has a longer service life. In other alternative embodiments, the first limiting member 123 and the second limiting member 124 may also be made of elastic materials, such as rubber, resin, and spring steel.

In some embodiments, a spring may be further disposed between the limiting rod 121 and the base 11 to reset the limiting rod 121; furthermore, the spring can be sleeved on the second limiting member 124, and two ends of the spring are respectively abutted against the limiting rod 121 and the base 11; it can be understood that the second limiting member 124 provides a guide for the compression and decompression of the spring to avoid the spring from being dislocated during the compression and decompression processes, thereby ensuring the stability of the reset of the limiting rod 121.

In some embodiments, the connection manner of the abutting element 132 and the transmission member 131 is a rotational connection, for example, the abutting element 132 is provided with a nut structure, the transmission member 131 is correspondingly provided with a thread structure, and the abutting element 132 is connected with the transmission member 131 by a rotational manner, which can be quickly detached when the abutting element 132 needs to be replaced or repaired, and meanwhile, the entire structure is not damaged, which is convenient for replacement. In other embodiments, the abutting member 132 is directly fixed to the transmission member 131, or a combination of rotation and fixing is adopted, which can prevent the connecting position between the abutting member 132 and the transmission member 131 from being loosened, thereby affecting the movement of the transmission member 131 and the limiting rod 121.

The embodiment of the application does not limit the specific transmission mode of the transmission member 131, the transmission mode of the transmission member 131 may be at least one of direct transmission, lever transmission, push-pull transmission, cam transmission and gear transmission, and the transmission member 131 may drive the limiting rod 121 to transmit in the above transmission mode, so as to realize blocking and unblocking of the limiting rod 121 on the conveying device 40. The specific transmission structure and transmission manner of the transmission member 131 will be described in detail below.

As shown in fig. 9 to 10, in some embodiments, the present application provides a conveyor line body 1, where the conveyor line body 1 includes the derailing prevention structure 10, the frame 20, the conveying guide 30, and the conveying device 40. The base 11 is detachably arranged on the rack 20, the conveying guide rail 30 is arranged on the rack 20, and the conveying device 40 is arranged on the conveying guide rail 30 and is in fit connection with the conveying guide rail 30; wherein at least part of the stopper rod 121 is located in the length direction of the conveying guide 30 to limit the movement of the conveying device 40 on the conveying guide 30. When the stop rod 121 achieves the blocking function, the conveying device 40 collides with the stop rod 121 to block the conveying device 40 from continuing to move; when the abutting part 132 is displaced by an external force, the driving member 131 drives the limiting rod 121 to rotate by a certain angle, so as to release the blocking of the conveying device 40 on the conveying guide rail 30, and the conveying line 1 has a more stable conveying environment.

Conveyor 40 moves on conveyor 30, conveyor 30's length and direction have limited conveyor 40's distance of movement and direction, and frame 20 supplies conveyor 30 to stably connect, and in some embodiments, base 11 of derailing prevention structure 10 can be pulled down from frame 20, is convenient for place derailing prevention structure 10 in the different positions that need, for example sets up near the both ends of conveyor 30 to reduce conveyor 1 because the machine that crashes or cuts off the power supply thereby leads to conveyor 40 to derail's probability. Wherein, part of the limiting rod 121 is located on the moving path of the conveying device 40 and in a blocking state, and part of the limiting rod 121 is close to the conveying guide rail 30 to limit the movement of the conveying device 40.

The conveyor line body 1 further comprises a docking module 50, the docking module 50 has a thimble 51, the thimble 51 has at least one abutting surface 511, and the abutting surface 511 is used for abutting against the abutting piece 132; as shown in fig. 9, the direction indicated by the arrow at B in the figure is a first direction B, and the direction indicated by the arrow at C is a second direction C, so that the docking module 50 can perform docking movement along the first direction B or the second direction C, and thus vertical or horizontal docking is realized. The abutting surface 511 is an inclined surface, when the docking module 50 approaches the abutting part 132, the abutting surface 511 abuts against the abutting part 132, so that the abutting part 132 moves along the abutting surface 511, thereby driving the limiting rod 121 to rotate, so as to release the limitation of the limiting rod 121 on the movement of the conveying device 40, so that the conveying guide rail 30 is not blocked, and the conveying device 40 can continue to move.

When the connection module 50 is connected with the conveying guide rail 30 of the conveying line body 1 up and down, the connection module 50 realizes connection movement along the first direction B. The docking module 50 is provided with an ejector pin 51 at one side close to the abutting piece, the ejector pin 51 is used for abutting against the abutting piece 132, the ejector pin 51 is provided with an abutting surface 511, the abutting surface 511 abuts against the abutting piece 132, and the abutting surface 511 is a smooth surface, so that the friction loss generated in the process of abutting against the abutting piece 132 can be reduced, and the service life is prolonged.

In the process that the docking module 50 moves along the first direction B, the abutting surface 511 moves along the first direction B to abut against the abutting piece 132, after the abutting surface 511 abuts against the abutting piece 132, the abutting surface 511 applies force to the abutting piece 132 along the first direction B, the force applied to the abutting piece 132 by the abutting surface 511 has component force along the first direction B and the second direction C, the abutting piece 132 is displaced under the action of the force, and the limiting rod 121 is driven to rotate by the transmission member 131; further, when the moving direction of the abutting surface 511 is close to the abutting piece 132, the abutting surface 511 abuts against the abutting piece 132 to enable a part of the limiting rod 121 to be away from the conveying guide rail 30 so as to ensure the normal passing of the conveying device 40, and when the moving direction of the abutting surface 511 is away from the abutting piece 132, the abutting surface 511 abuts against the abutting piece 132 to enable a part of the limiting rod 121 to be close to the conveying guide rail 30 so as to block the conveying device 40.

When the docking module 50 performs a horizontal docking motion, the docking module 50 performs a docking motion along the second direction C, i.e. the motion direction of the docking module 50 is perpendicular to the first direction B. The docking module 50 performs a docking movement along a second direction C, which is a direction in which the docking module 50 moves from one end far away from the conveying rail 30 to the end close to the conveying rail 30 when horizontally docked. The contact surface 511 of the thimble 51 contacts with the contact part 132, the contact surface 511 applies a force in the second direction C to the contact part 132, the contact part 132 is displaced under the force, the transmission member 131 drives the limiting rod 121 to rotate, and the limiting rod 121 is partially away from the conveying guide rail 30 to ensure the normal passing of the conveying device 40.

When the docking module 50 does not perform docking movement or the docking module 50 is far away from the conveying guide 30, the thimble 51 moves together with the docking module 50, the contact surface 511 is released from contact with the contact member 132, the thimble 51 no longer provides external force to the contact member 132, and the transmission member 131 no longer provides supporting force for the limiting rod 121 to rotate the limiting rod 121. The limiting rod 121 rotates to gradually approach and abut against the first limiting member 123, at this time, a part of the limiting rod 121 is located in the length direction of the conveying guide rail 30, and the derailing prevention structure 10 blocks the conveying device 40 to prevent the conveying device 40 from being punched out of the conveying guide rail 30.

As shown in fig. 2, 3 and 9, in some embodiments, the drive pattern of the drive member 131 is configured as a direct drive. The transmission member 131 comprises a connecting rod 1311 and a rotating shaft 1313, the rotating shaft 1313 is disposed on the base 11 and rotatably connected with the limiting rod 121, and the limiting rod 121 can rotate around the rotating shaft 1313; the two ends of the connecting rod 1311 are connected with the limiting rod 121 and the abutting part 132 respectively, so that the limiting rod 121 can rotate for a certain angle under the transmission of the connecting rod 1311, and the conveying device 40 on the conveying guide rail 30 is blocked or unblocked, so that the conveying line body 1 has a more stable conveying environment.

By arranging the connecting rod 1311 to connect with the abutting part 132 and the limiting rod 121, when the abutting part 132 is displaced by the force provided by the thimble 51, the connecting rod 1311 drives the limiting rod 121 to rotate by a certain angle around the rotating shaft 1313, and the part of the limiting rod 121 is far away from the initial position, so that the blocking of the conveying device is removed. Specifically, when the docking module 50 performs docking movement, the docking module 50 moves from one end far away from the conveying guide rail 30 to the end close to the conveying guide rail 30, the abutting surface 511 of the thimble 51 abuts against the abutting piece 132, the abutting surface 511 applies force to the abutting piece 132, and the abutting piece 132 is displaced under the action of force; the abutting member 132 drives the limiting rod 121 to rotate around the rotating shaft 1313 via the connecting rod 1311, and the limiting rod 121 is partially away from the conveying guide 30 to ensure the normal passing of the conveying device 40. When the abutting surface 511 is no longer abutted against the abutting member 132, the limiting rod 121 rotates toward the initial position under the influence of the vertical downward gravity, and returns to the blocking state of the initial position, the abutting member 132 displaces under the action of force, and the connecting rod 1311 drives the abutting member 132 to displace. The direct transmission mode structure is simpler, has saved the material, and the cost is reduced is convenient for install and dismantle.

As shown in fig. 4, 5 and 9, in some embodiments, the actuation of the actuation member 131 is a lever actuation. The limiting rod 121 can block or unblock the conveying device 40 on the conveying guide rail 30 in a lever transmission mode. Specifically, the transmission member 131 includes a driven rod 1314, a rotation shaft 1313 and a transmission rod 1312, the driven rod 1314, the rotation shaft 1313 and the transmission rod 1312 are sequentially disposed, one end of the transmission rod 1312 is connected to the limit rod 121, the rotation shaft 1313 is rotatably disposed on the base 11, one end of the driven rod 1314 is connected to the abutting part 132, and after the abutting part 132 abuts against the abutting surface 511 and is displaced, the driven rod 1314 and the transmission rod 1312 are driven to displace, so that the limit rod 121 can rotate by a certain angle to block or unblock the conveying device 40 on the conveying rail 30, and the conveying line body 1 has a more stable conveying environment.

When the docking module 50 is docked up and down along the first direction B or docked horizontally along the second direction C, the abutment surface 511 abuts against the abutment member 132, the abutment member 132 is pushed by an external force to displace, and the base 11 is provided with a slide way for displacing the transmission rod 1312 and the driven rod 1314. For example, when the docking module 50 is docked horizontally, the abutment surface 511 abuts against the abutment 132 and urges the abutment 132 so that the abutment 132 starts to displace, the driven lever 1314 also displaces in the slide in synchronism with the abutment 132, the transmission lever 1312 displaces in the other slide, and the driven lever 1314 and the transmission lever 1312 rotate about the rotation shaft 1313. When the first connecting portion 1211, the third connecting portion 1213 and the second connecting portion 1212 are sequentially arranged along the length direction a of the stopper rod 121, the third connecting portion 1213 is a fulcrum, and the second connecting portion 1212 is a power point; when the distance from the center of gravity of the stopper rod 121 to the third connecting portion 1213 is greater than the distance between the second connecting portion 1212 and the third connecting portion 1213, the transmission rod 1312 moves by a small distance, so that the stopper rod 121 rotates by a large angle, the transmission manner is short, the length of the slide rail provided on the base 11 can be reduced, and the structure of the base 11 is firmer. When the first connection portion 1211, the second connection portion 1212, and the third connection portion 1213 are sequentially disposed along the length direction a of the stopper rod 121, the rotation direction of the stopper rod 121 is the same as the rotation direction of the transmission rod about the rotation shaft 1313. Further, the distance between the transmission rod 1312 and the rotation shaft 1313 and the distance between the rotation shaft 1313 and the driven rod 1314 are changed, so that the transmission manner of the transmission member 131 is more efficient.

In some embodiments, the shaft 1313 may be replaced with a cross torsion spring compliant bearing. One bearing seat of the flexible bearing is fixedly connected with the base 11, and the other bearing seat of the flexible bearing is fixedly connected with the limiting rod 121; with the rotation of the limiting rod 121 relative to the base 11, the torsion of the torsion spring in the flexible bearing is increased, and the rotation of the limiting rod 121 relative to the base 11 is prevented; further, the torsion spring in the flexible bearing can reset the limiting rod 121, so that the limiting rod 121 is guaranteed to have a stable blocking effect.

As shown in fig. 6 to 9, in some embodiments, in derailing prevention structure 10, the transmission manner of transmission member 131 is set as cam transmission. The limiting rod 121 can block or unblock the conveying device 40 on the conveying guide rail 30 in a cam transmission mode.

Specifically, the position-limiting component 12 has a blocking tooth 125, the transmission component 131 has a cam 15, the blocking tooth 125 is fixed on one side of the position-limiting rod 121 close to the cam 15 for cooperating with the cam 15, and the cam 15 is rotatably connected with the base 11 around a central rotating shaft 1316; when the cam 15 rotates around the rotating shaft 1316, the abutting position of the cam and the blocking tooth 125 changes gradually, and the blocking tooth 125 drives the limiting rod 121 to rotate for a certain angle, so as to block or unblock the conveying device.

The cam 15 has a first contact surface 151 and a second contact surface 152 adjacent to each other; when the cam 15 rotates, the blocking tooth 125 forms a displacement curve on the first abutting surface 151 and the second abutting surface 152, the slope of the displacement curve at the abutting position of the first abutting surface 151 and the second abutting surface 152 is zero, and during the movement process of the blocking tooth 125, the blocking tooth 125 moves from the root circle position to the tip circle position of the cam 15 to drive the limiting rod 121 to rotate relative to the base 11, and the part of the limiting rod 121 is far away from the conveying guide rail 30, so that the limiting rod 121 plays a role in releasing the blocking of the conveying device 40 on the conveying guide rail 30.

When the docking module 50 performs a vertical docking movement along the first direction B, the thimble 51 gradually approaches the docking member 132 and abuts against the docking member 132, the docking surface 511 abuts against the docking member 132, the docking module 50 continues the docking movement, the thimble 51 provides a supporting force for the docking member 132, so that the docking member 132 can rotate, the docking member 132 rotates to drive the central rotating shaft 1316 connected thereto to rotate in the same direction, and the cam 15 rotates by the driving of the central rotating shaft 1316. As shown in fig. 7, the blocking tooth 125 is located between the third connecting portion 1213 and the first connecting portion 1211 of the limiting rod 121, the position of the blocking tooth 125 on the limiting rod 121 is a power point, the center of gravity of the limiting rod 121 is a resistance point, the position of the third connecting portion 1213 is a fulcrum, that is, the power point and the resistance point of the limiting rod 121 are on the same side of the fulcrum, and the power point is closer to the fulcrum than the resistance point, so that the moving distance of the blocking tooth 125 when the limiting rod 121 rotates can be reduced. The limiting rod 121 rotates counterclockwise under the action of the thimble 51, the cam 15 also rotates counterclockwise, at this time, the stop tooth 125 moves on the second abutting surface 152 to drive the limiting rod 121 connected with the stop tooth 125 to rotate until the limiting rod moves to the abutting position of the first abutting surface 151 and the second abutting surface 152, at this time, the stop tooth 125 is located at the addendum circle of the cam 15, the limiting rod 121 is partially far away from the conveying guide rail 30, the blocking effect is removed, and the conveying device 40 is ensured to move on the conveying guide rail 30. Continuously, when the blocking tooth 125 is located at the addendum circle of the cam 15 and rotates counterclockwise, the blocking tooth 125 abuts against the first abutting surface 151 until the blocking tooth 125 moves to the abutting position of the first abutting surface 151 and the second abutting surface 152, at this time, the blocking tooth 125 is located at the dedendum circle of the cam 15, and the limiting rod 121 is located at the initial position, so as to block the conveying device 40. As the cam 15 continues to rotate around the shaft, the blocking teeth 125 repeat the above movement, thereby blocking and unblocking the stopper rod 121. The same applies to the clockwise rotation of the cam 15.

In the cam transmission mode, the number of the transmission members 131 is small, the structure is simple, the blocking effect of the derailing prevention structure 10 on the conveying device 40 can be achieved by reasonably designing the profile curve of the cam 15, and meanwhile, when the connection module 50 moves to the next position after being connected, the limiting rod 121 can automatically return to the initial position.
