Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0027] At present, in the process of pig breeding, accurate measurement of body weight and feed has important significance for optimizing feeding management and improving production efficiency. In the process of measuring pigs, it is often necessary to measure the body weight and / or feed of pigs one by one.

[0028] In the prior art, when pigs enter and exit the fence during the measurement process, manual operation or electronic equipment is usually needed to control the opening and closing of the fence door. If the fence is opened or closed by manual operation, not only is the efficiency low, but also because the pigs are close to the people, it is easy to cause danger. If electronic equipment is used to control the opening and closing of the fence, there are problems such as high equipment cost, complex maintenance and possible failure.

[0029] Therefore, the pig measurement in the prior art has the problems of low control efficiency of the fence door or high equipment cost.

[0030] Therefore, the pig measurement in the prior art has the problems of low control efficiency of the fence door or high equipment cost.

[0031] Please refer to Figure 1 and Figure 2The pig individual weighing device comprises a fence 1, a mechanical linkage 2, a trough 3 and a weighing mechanism 4. The fence 1 is used to restrict the pig in a specific area, and a space for the pig to enter is formed between the front end and the tail end of the fence 1. The tail end of the fence 1 is provided with a first opening 11, and is equipped with a tail door 6 to control the opening and closing of the opening; and a second opening 12 is further provided inside the fence 1, and is equipped with a front door 5 to realize the opening and closing function. The mechanical linkage 2 is installed between the tail door 6 and the front door 5, so that when one of the doors is opened, the other door will be automatically closed. The trough 3 is arranged close to the front end of the fence 1 and is in communication with the inside of the fence 1, and is used to hold the feed. The weighing mechanism 4 is connected to the trough 3, and can measure the change of the weight of the feed in the trough 3, so as to realize the accurate determination of the feeding amount of the pig.

[0032] Please refer to Figure 1 and Figure 2 The mechanical linkage 2 can be a linkage structure in which a plurality of pull rods are sequentially hinged, or can be a combined structure of a pull rod and other components, or can be other forms of transmission structure, such as a gear and rack combination or a pulley and rope device. These different mechanical linkage modes can all realize the interlocking function between the front door 5 and the tail door 6, so as to ensure that only one door is in an open state when the pig enters or leaves the fence 1, thereby avoiding the entry of other pigs.

[0033] Please refer to Figure 1 and Figure 2 The linkage process of the front door 5 and the tail door 6 is as follows: initially, the tail door 6 is closed, and the front door 5 remains open. When the pig hits the tail door 6 to make it open, the front door 5 will be automatically closed due to the action of the mechanical linkage 2; as the pig continues to enter the inside of the fence 1 and releases the tail door 6 from hitting the front door 5, the front door 5 is gradually opened under the pushing of the pig, and the tail door 6 is again closed due to the action of the mechanical linkage 2. At this time, the pig has reached the front end of the fence 1 and can start eating. During the eating process of the pig, the pig pushes against the front door 5 to keep the front door 5 open, and the tail door 6 remains closed due to the action of the mechanical linkage 2. Since the tail door 6 is closed, other pigs cannot enter the inside of the fence 1. When the pig finishes eating, the pig releases the front door 5 and reaches the tail door 6 to push it open, and then leaves the fence 1.

[0034] Please refer to Figure 1 and Figure 2The specific measurement process can be that before the pig enters the fence 1, the weighing mechanism 4 will first measure the feed in the trough 3; and after the pig finishes eating and leaves the fence 1, the weighing mechanism 4 will be measured again to determine the consumption of feed. It should be noted that the measurement requirement can be determined according to the actual situation, and the specific order and number of measurements of the embodiment of the present application are not limited. For example, in some embodiments, the body weight of the pig can be measured first, and then the feed consumption is recorded; or both can be measured at the same time. In addition, the device can also be equipped with a data recording device for storing the results of each measurement, which is convenient for subsequent analysis and management. The data recording device can be connected with the weighing mechanism 4, and the data can be transmitted to external equipment such as a computer or a cloud server through wireless or wired mode, so as to realize centralized management and long-term preservation of data.

[0035] The embodiment of the present application realizes the automatic control of the front door 5 and the tail door 6 by adopting the mechanical linkage mechanism 2, which not only avoids manual intervention, but also significantly reduces the cost of the equipment. Compared with the electronic control device, this mechanical structure is more stable and reliable, reducing the risk of measurement interruption caused by equipment failure. At the same time, the operation process of the device is simple and intuitive, and it can be put into use without complex training, which is suitable for various scales of farms. Therefore, the pig individual weighing device provided by the embodiment of the present application can realize the opening and closing of the fence 1 without manual intervention, while reducing the cost of the pig individual weighing device.

[0036] In some embodiments, please refer to Figure 1 and Figure 2 In order to make the pig keep the tail door 6 closed during eating, it is ensured that the pig can support or resist the front door 5 when eating, and the space layout in the fence 1 is reasonably set.

[0037] Specifically, please refer to Figure 1 and Figure 2, a space is formed between the front end and the tail end of the fence 1, which is sufficient for the pig to enter completely. When the front door 5 is closed, the space is divided into two parts by the front door 5: a first space 101 away from the trough 3 and a second space 102 close to the trough 3. After the pig enters the fence 1 through the first opening 11, it will first enter the first space 101, and then enter the second space 102. Obviously, the length of the second space 102 should be greater than or equal to the width of the front door 5, so as to ensure that the front door 5 can rotate freely in the second space 102 and open the second opening 12. However, the sum of the width of the front door 5 and the length of the pig should be greater than the length of the second space 102, so that after the pig enters the second space 102, due to the limitation of the length of the second space 102, the pig will occupy the rotation area of the front door 5, so that the front door 5 cannot be closed due to the obstruction of the pig. That is, the pig will keep the front door 5 open by its body, and the tail door 6 will be kept closed due to the action of the mechanical linkage mechanism 2, so as to ensure that other pigs cannot enter the inside of the fence 1 from the tail end during the pig feeding.

[0038] The embodiment of the present application effectively avoids the measurement error caused by multiple pigs entering the fence 1 at the same time by reasonably arranging the inside space of the fence 1.

[0039] In some embodiments, referring to Figure 1 and Figure 2 , in order to make the front door 5 and the tail door 6 achieve a more ideal opening and closing state, the mechanical linkage mechanism 2 is reasonably arranged.

[0040] Referring to Figure 1 and Figure 2 , the mechanical linkage mechanism 2 includes a pull rod 21, a rotating piece 22 and a tension spring 23 (it should be noted that the tension spring 23 in the figure is only a schematic structure, and the spring shape of the tension spring 23 is not fully shown). The rotating piece 22 has a rotating center 221 and a first end portion 222 and a second end portion 223 around the rotating center 221, and the rotating piece 22 is arranged between the pull rod 21 and the tension spring 23. One end of the pull rod 21 is rotatably connected to the front door 5, and the other end is rotatably connected to the first end portion 222 of the rotating piece 22. One end of the tension spring 23 is connected to the tail door 6, and the other end is connected to the second end portion 223 of the rotating piece 22, so as to provide a pushing force or a pulling force to the tail door 6. The rotating piece 22 is arranged on the frame of the fence 1 and can rotate around its rotating center 221. Among them, in the process of opening the front door 5, the pull rod 21 moves towards the front end of the fence 1 and drives the rotating piece 22 to rotate, and the tension spring 23 is stretched under the drive of the rotating piece 22 to close the tail door 6; in the process of opening the tail door 6, the tension spring 23 is stretched and drives the rotating piece 22 to rotate, and the pull rod 21 closes the front door 5 with the rotation of the rotating piece 22.

[0041] Referring to Figure 1 andFigure 2 The specific implementation principle of the mechanical linkage mechanism 2 is as follows:

[0042] When the pig hits the tail door 6, the tail door 6 is subjected to an external force and begins to open, at which time the tension spring 23 is stretched, and simultaneously pulls the first end portion 222 of the rotating member 22, so that the rotating member 22 rotates around its rotating center 221. The rotation of the rotating member 22 drives the pull rod 21 to move backward, thereby pushing the front door 5 to close. During this process, the connection between the pull rod 21 and the rotating member 22 ensures that the front door 5 and the tail door 6 move synchronously and mutually exclude each other, avoiding the possibility of both doors being opened at the same time.

[0043] In the state that the tail door 6 is opened, the tail door 6 always maintains a certain tension due to the elastic restoring force of the tension spring 23, preventing the tail door 6 from uncontrollably closing due to the sudden disappearance of the external force. When the pig enters the fence 1 and releases the tail door 6, the tension spring 23 gradually returns to its original state, driving the rotating member 22 to rotate in the opposite direction. At this time, the pull rod 21 moves forward, pushing the front door 5 to open or slightly open, while the tail door 6 automatically closes under the action of the tension spring 23.

[0044] As the pig enters the inside of the fence 1 and pushes the front door 5 open, the front door 5 is further opened under the push of the pig, while the tail door 6 is closed more tightly due to the action of the mechanical linkage mechanism 2. At this time, the pig has reached the front end of the fence 1 and can start eating. During the pig's eating process, the pig pushes against the front door 5, keeping the front door 5 open, while the tail door 6 remains closed due to the action of the mechanical linkage mechanism 2. Because the tail door 6 is closed, other pigs cannot enter the inside of the fence 1. When the pig finishes eating, the pig will release the front door 5 and reach the tail door 6 to push it open, and then leave the fence 1. In this way, the mechanical linkage mechanism 2 completes a complete linkage cycle.

[0045] The main roles of the pull rod 21, the rotating member 22, and the tension spring 23 are as follows: the pull rod 21 plays a key role in connection and transmission in the mechanical linkage mechanism 2. One end of the pull rod 21 is connected to the front door 5, and the other end is connected to the first end portion 222 of the rotating member 22. Through its own movement, the pull rod 21 transmits the action of the front door 5 to the rotating member 22, thereby triggering the operation of the entire linkage mechanism. When the pig pushes the front door 5, the pull rod 21 moves forward, pushing the rotating member 22 to rotate, which ensures that the tail door 6 can be closed in time to prevent other pigs from entering the fence 1.

[0046] Please refer to Figure 1 and Figure 2, the rotating piece 22 as the core component of the mechanical linkage mechanism 2 plays a role of force conversion and distribution, so that the force between the pull rod 21 and the tension spring 23 can be effectively transmitted through the rotating center 221. When the tail door 6 is opened by external force, the second end 223 of the rotating piece 22 is pulled, thereby driving the first end 222 to exert force on the pull rod 21. This force transmission mode not only realizes the interlocking function of the front door 5 and the tail door 6, but also improves the smoothness and reliability of the whole mechanism operation.

[0047] Please refer to Figure 1 and Figure 2 , the tension spring 23 provides the necessary elastic restoring force for the mechanical linkage mechanism 2. One end of the tension spring 23 is connected to the tail door 6, and the other end is connected to the second end 223 of the rotating piece 22, which is stretched and stores elastic potential energy during the opening of the tail door 6. When the pig releases the tail door 6, the tension spring 23 quickly returns to its original state, driving the rotating piece 22 to rotate in the opposite direction, thereby realizing the automatic closing of the tail door 6 and the opening of the front door 5. In addition, since the tension spring 23 can also be twisted, the activity range of the mechanical linkage mechanism 2 can be expanded, that is, the mechanical linkage mechanism 2 can sway within a certain range, thereby reducing the phenomenon of the mechanical linkage mechanism 2 being stuck.

[0048] Through the synergistic effect of the pull rod 21, the rotating piece 22 and the tension spring 23, the opening and closing effect of the front door 5 and the tail door 6 is improved, and the stability and reliability of the device are further enhanced.

[0049] In some embodiments, please refer to Figure 1 and Figure 2 It can be understood that in order to prevent the pig from entering the pig single scale measuring device in the idle state, the tail door 6 needs to be automatically kept closed, so the tension spring 23 must be stretched. However, due to the stretching effect of the tension spring 23, the tail door 6 is closed too tightly, making it difficult for the pig to knock it open. Therefore, in order to facilitate the pig to easily knock the tail door 6 open, a torsional spring 7 is installed at the rotating shaft of the tail door 6.

[0050] Specifically, please refer to Figure 1 and Figure 2 , one end of the torsional spring 7 is fixed on the frame of the fence 1, and the other end is connected with the tail door 6 to drive the tail door 6 to rotate outward. The specific implementation principle of the torsional spring 7 is: when the pig hits the tail door 6, the torsional spring 7 is compressed and stores elastic potential energy. At this time, the tail door 6 starts to open under the action of external force, and the reverse elastic force of the torsional spring 7 will help the tail door 6 to maintain a certain opening trend. In this way, on the one hand, the tail door 6 can sway when it is opened, and on the other hand, the force required by the pig to push the tail door 6 open is reduced. This design not only enables the tail door 6 to automatically close in the idle state, but also avoids the problem that the tail door 6 is difficult to open due to excessive tension of the tension spring 23.

[0051] The tail door 6 can automatically return to the closed state under the elastic property of the torsional spring 7 without external force, and the force required by the pig to push open the tail door 6 is reduced.

[0052] In some embodiments, in order to ensure that the pig can travel along the predetermined path after entering the entrance space 10 of the fence 1 and prevent other pigs from entering the fence 1, the pig single scale measuring device is additionally provided with a width adjusting plate 81 to adjust the width of the entrance space 10 of the fence 1.

[0053] Specifically, please refer to Figure 1 and Figure 2 The width adjusting plate 81 is arranged inside the fence 1 and extends along the front-rear direction of the fence 1 (the front-rear direction of the fence 1 is also the length direction of the fence 1, which is indicated by a dashed line a in the figure) to divide the internal space of the fence 1 into the entrance space 10 and the remaining space; wherein the width adjusting plate 81 can move in the width direction of the fence 1 (the width direction is indicated by a dashed line b in the figure) to change the width of the entrance space 10 and the remaining space.

[0054] In specific operation, the position of the width adjusting plate 81 can be adjusted according to the size of the pig and actual needs. When it is necessary to limit the width of the entrance space 10, the width adjusting plate 81 can be moved to the center of the fence 1, thereby reducing the width of the entrance space 10 and ensuring that only one pig can pass through smoothly each time.

[0055] Through the arrangement of the width adjusting plate 81, on the one hand, the fence 1 can adapt to pigs of different sizes and ensure that only one pig enters the measurement area each time; on the other hand, it can effectively prevent multiple pigs from entering the fence 1 at the same time, thereby avoiding confusion of the measurement data. In addition, the width adjusting plate 81 can also guide the pig to travel along the predetermined path, reduce the random movement of the pig in the fence 1, and further improve the accuracy of the measurement.

[0056] In some embodiments, please refer to Figure 2 In order to facilitate the adjustment of the position of the width adjusting plate 81, a width adjusting assembly 82 is also arranged. Specifically, the width adjusting assembly 82 is connected between the width adjusting plate 81 and the fence 1 to drive the width adjusting plate 81 to move in the width direction of the fence 1; the width adjusting assembly 82 includes a push rod 821, a sliding groove body 822 and a sliding block 823: one end of the push rod 821 is connected to the fence 1; the sliding groove body 822 is arranged on the width adjusting plate 81, and the sliding groove body 822 has a sliding groove along the front-rear direction of the fence 1; the sliding block 823 is connected to the other end of the push rod 821, and the sliding block 823 can slide in the sliding groove.

[0057] Please refer toFigure 2 In specific implementation, the push rod 821 is pushed, the sliding block 823 slides in the sliding groove, and the width adjusting plate 81 is driven to move along the width direction of the fence 1.

[0058] The embodiment of the present application can flexibly adjust the position of the width adjusting plate 81, so as to accurately control the width of the fence 1 entering the space 10, by arranging the width adjusting assembly 82. The coordinated action of the push rod 821, the sliding groove body 822 and the sliding block 823 ensures the stability and accuracy of the width adjusting plate 81 during movement. When it is necessary to adjust the width of entering the space 10, the operator only needs to push the push rod 821, and the sliding block 823 will slide in the sliding groove, driving the width adjusting plate 81 to move along the width direction of the fence 1.

[0059] In some embodiments, referring to Figure 2 In order to ensure that the position of the width adjusting plate 81 can be fixed after being adjusted, the sliding block 823 is designed as a special-shaped nut.

[0060] In specific implementation, referring to Figure 2 By rotating the special-shaped nut, it can be fixed at a specific position in the sliding groove, so as to lock the current position of the width adjusting plate 81.

[0061] The embodiment of the present application can effectively prevent the width adjusting plate 81 from being displaced due to external force during use by adopting the special-shaped nut as the fixing device of the sliding block 823, so as to ensure that the width of entering the space 10 remains stable after being adjusted.

[0062] In some embodiments, referring to Figure 3 and Figure 4 In order to weigh the food intake of the pigs, the weighing mechanism 4 is arranged to include a connecting structure 41 and a sensor 42, the sensor 42 includes a fixed end 421 and a sensitive end 422 arranged below the fixed end 421, the sensitive end 422 is connected to the connecting structure, the trough 3 is arranged outside the front end of the fence 1, and the trough 3 is connected to the connecting structure 41. Correspondingly, the bottom end of the trough 3 should be arranged in suspension. In this way, the gravity of the trough 3 is transmitted to the connecting structure 41, and then to the sensitive end 422 of the sensor 42, so that the food intake of the pigs can be weighed.

[0063] Referring to Figure 3 and Figure 4It can be understood that the sensitive end 422 of the sensor 42 will be displaced relative to the fixed end 421 when subjected to external force; the force suffered by the trough 3 when the pig hits will be transmitted to the sensitive end 422 of the sensor 42. Moreover, the force with which the pig hits the trough 3 cannot be predicted, and such unpredictable force will be transmitted to the sensor 42, causing the measurement range to exceed the limit and thus causing damage. Therefore, in order to reduce the risk of damage to the sensor 42, the pig individual weight measuring device is further provided with a limit protection mechanism 9.

[0064] Specifically, please refer to Figure 3 and Figure 4 The limit protection mechanism 9 is arranged on the movement track of the connecting structure 41; in the process of driving the connecting structure 41 and the sensitive end 422 of the sensor 42 to move by the trough 3, the limit protection mechanism 9 abuts against the connecting structure 41 to limit the movement of the connecting structure 41 and the sensitive end 422 of the sensor 42. In other words, when the trough 3 is hit by external force, the connecting structure 41 will move with the displacement of the sensitive end 422 of the sensor 42; however, the limit protection mechanism 9 is arranged on the movement track of the connecting structure 41, and when the connecting structure 41 approaches the limit position, it will contact the limit protection mechanism 9, so that the limit protection mechanism 9 prevents the connecting structure 41 from further movement.

[0065] The embodiment of the present application effectively avoids the damage of the sensor 42 due to excessive external force by arranging the limit protection mechanism 9.

[0066] In some embodiments, please refer to Figure 3 and Figure 4 In order to prevent the movement of the sensitive end 422 of the sensor 42 from exceeding the predetermined range, the first abutting member 412 and the first limiting member 91 are arranged. When the two components contact, they will jointly act to prevent excessive movement of the sensitive end 422 of the sensor 42.

[0067] Specifically, please refer to Figure 3 and Figure 4 The connecting structure 41 comprises the connecting body 411 and the first abutting member 412 connected to the connecting body 411, and the connecting body 411 is connected between the sensitive end 422 of the sensor 42 and the trough 3. The limit protection mechanism 9 comprises the first limiting member 91 fixedly arranged on the movement track of the connecting structure 41. The first limiting member 91 is sleeved outside the connecting body 411 to limit the movement of the connecting body 411 in the horizontal direction (any direction in the plane formed by the length direction a and the width direction b of the fence 1). In the process of driving the connecting body 411, the first limiting member 91 and the sensitive end 422 of the sensor 42 to move by the trough 3, the first abutting member 412 will contact the first limiting member 91, thereby preventing the further downward movement of the sensitive end 422 of the sensor 42.

[0068] Please refer to Figure 3 and Figure 4 When the trough 3 is impacted by a large external force, the connecting body 411 drives the first abutting piece 412 to move downward, and the first limiting piece 91 is fixed at a preset position and does not move. Once the first abutting piece 412 contacts the first limiting piece 91, a physical block is formed to prevent the sensitive end 422 of the sensor 42 from continuing to displace, thereby avoiding damage due to exceeding the movement range.

[0069] The first abutting piece 412 and the first limiting piece 91 cooperate to enhance the durability of the sensor 42.

[0070] In some embodiments, please refer to Figure 3 and Figure 4 In order to enhance the stability of the connecting structure 41, the first abutting piece 412 is arranged as a component for enhancing the stability of the connecting structure 41.

[0071] Specifically, please refer to Figure 3 and Figure 4 The connecting body 411 includes at least two vertical rods 4111 and a cross beam 4112. The vertical rods 4111 are arranged in at least two in the horizontal direction (the horizontal direction includes the front-rear direction of the fence 1 and the width direction of the fence 1), the bottom ends of the vertical rods 4111 are connected to the trough 3, the cross beam 4112 is arranged in extension along the horizontal direction and is connected to the two vertical rods 4111; the cross beam 4112 is connected to the sensitive end 422 of the sensor 42; wherein the first abutting piece 412 is arranged in extension along the horizontal direction and is connected to the two vertical rods 4111; the first limiting piece 91 is sleeved on the vertical rod 4111, and the trough 3, the first limiting piece 91, the first abutting piece 412 and the cross beam 4112 are arranged in sequence along the vertical direction (the vertical direction is indicated by a dashed line c in the figure).

[0072] Therefore, the first abutting piece 412 enhances the connection rigidity between the vertical rods 4111 through its transverse extension structure feature, thereby reducing the shaking and deformation of the connecting structure 41 when subjected to force. Therefore, the first abutting piece 412 not only serves to abut against the first limiting piece 91, but also acts as a structure similar to the cross beam 4112 to increase the stability of the connecting structure 41.

[0073] The first abutting piece 412 is arranged as a component having the dual functions of abutting and enhancing stability, which not only limits the movement range of the sensitive end 422 of the sensor 42, but also enhances the rigidity of the connecting structure 41.

[0074] In some embodiments, please refer to Figure 3 and Figure 4In order to avoid the pig colliding with the trough 3 at high speed, the first abutting part 412 collides with the second limiting part 94, and in the case of the pig suddenly releasing the trough 3, the sensitive end 422 of the sensor 42 rebounds quickly and is damaged, the limiting protection mechanism 9 is particularly provided with a buffer device.

[0075] Specifically, please refer to Figure 3 and Figure 4 The top end of the vertical rod 4111 penetrates the cross beam 4112 and extends upward relative to the cross beam 4112. The limiting protection mechanism 9 further comprises a second abutting part 92 and a second limiting part 94. The second abutting part 92 is arranged on the outer wall of the top end of the vertical rod 4111 and is located above the cross beam 4112; the elastic part 93 is sleeved on the top end of the vertical rod 4111; one end of the elastic part 93 abuts against the second abutting part 92, and the other end abuts against the cross beam 4112; the second limiting part 94 is arranged on the outer wall of the vertical rod 4111, and the second limiting part 94 abuts against the side of the cross beam 4112 away from the second abutting part 92; the cross beam 4112 is movable up and down along the vertical rod 4111. The elastic part 93 can be a spring.

[0076] Please refer to Figure 3 and Figure 4 The buffer principle of the elastic part 93 is as follows:

[0077] When the pig collides with the trough 3 at high speed, the vertical rod 4111 is subjected to a downward impact force, driving the second abutting part 92 to move downward, at this time the elastic part 93 is compressed, absorbing part of the impact energy, thereby reducing the collision force between the first abutting part 412 and the first limiting part 91. The buffering effect of the elastic part 93 effectively reduces the risk of deformation of the connecting structure 41 due to excessive instantaneous force, and also avoids damage to the sensitive end 422 of the sensor 42 due to violent movement.

[0078] In the case of the pig suddenly releasing the trough 3, the sensitive end 422 of the sensor 42 will rebound quickly due to the elastic restoring force, at this time the elastic part 93 plays a role again. Since one end of the elastic part 93 abuts against the second abutting part 92 and the other end abuts against the cross beam 4112, it can provide a certain resistance during the rebounding of the sensitive end 422, slow down the rebounding speed, thereby avoiding the sensitive end 422 from exceeding its safe movement range due to excessive rebounding.

[0079] In addition, due to the combined action of the second limiting part 94, the safety of the device is further enhanced. When the vertical rod 4111 moves upward to the limit position, the second limiting part 94 contacts the cross beam 4112, forming a physical barrier to prevent the vertical rod 4111 from continuing to move upward. This double protection mechanism not only improves the reliability of the entire mechanism, but also prolongs the service life of the sensor 42 and the connecting structure 41.

[0080] The elastic piece 93, the second abutting piece 92 and the second limiting piece 94 are arranged, so that the buffering performance and safety of the limiting protection mechanism 9 are improved.

[0081] In some embodiments, referring to Figure 3 and Figure 4 , in order to make the elastic piece 93 move smoothly when the second abutting piece 92 and the second limiting piece 94 contact each other during buffering, a guide groove and a guide block 95 are arranged.

[0082] Specifically, referring to Figure 3 and Figure 4 , the cross beam 4112 is formed with a guide groove which is downwardly open and penetrates through both ends of the cross beam 4112, and the limiting protection mechanism 9 further comprises the guide block 95 which is connected to the two vertical rods 4111 and can enter and exit the guide groove along the opening direction of the guide groove; wherein, during compression of the elastic piece 93 by the cross beam 4112, the guide block 95 gradually exits the guide groove; during relaxation of the elastic piece 93 by the cross beam 4112, the guide block 95 gradually enters the guide groove.

[0083] Referring to Figure 3 and Figure 4 Figure 3 Figure 4 Figure 3 Figure 4 Figure 3 Figure 4 Figure 3 Figure 4 Figure 3 Figure 4 Figure 3 Figure 4 Figure 3 Figure 4 Figure 3 Figure 4 Figure 3 Figure 4 Figure 3 Figure 4 Figure 3 Figure 4 Figure 3 Figure 4 Figure 3 Figure 4 Figure 3 Figure 4 Figure 3 Figure 4 Figure 3 Figure 4 Figure 3 , the specific working principle of the guide block 95 and the guide groove is that, through cooperation of the guide block 95 and the guide groove, the movement track of the cross beam 4112 during up-down movement is kept smooth and stable. When the second abutting piece 92 and the cross beam 4112 compress the elastic piece 93, the guide block 95 gradually moves out along the opening direction of the guide groove, so as to avoid jamming or deviation caused by uneven force. During gradual relaxation of the elastic piece 93 by the second abutting piece 92 and the cross beam 4112, the elastic piece 93 gradually returns to the original state, and the guide block 95 re-enters the guide groove, further guiding the cross beam 4112 to return to the initial position. This design not only improves the overall stability of the connecting structure 41, but also effectively reduces mechanical vibration and noise caused by excessive impact force.

[0084] In addition, since the guide block 95 is connected to the two vertical rods 4111, the guide block 95 not only has a guiding effect, but also has an effect of enhancing the stability of the connecting structure 41.

[0085] The embodiment of the present application realizes control of the movement track of the cross beam 4112 and enhances the stability and impact resistance of the connecting structure 41 through the cooperative design of the guide groove and the guide block 95.

[0086] The above merely illustrates the embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation made according to the technical concept of the present application, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
