[0041] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0042] Combine Figure 8 and Figure 9 The trash can 200 needs to be cleaned regularly during use to improve urban environmental hygiene. When cleaning the trash can 200, it is necessary to connect the trash can 200 to the trash can turning mechanism 300. The trash can turning mechanism 300 can turn the trash can 200 to facilitate cleaning of the inner wall of the trash can 200. The trash can turning mechanism can be provided with a limit lock 100. In this way, when the trash can turning mechanism 300 turns the trash can 200, the limit lock 100 can lock the trailer handle 21 of the trash can 200, thereby preventing the trash can 200 from falling during the turning process. Therefore, by providing the limit lock 100 on the trash can turning mechanism 300, the stability of the trash can 200 during the turning process can be improved, and the size of the clamping portion 32 of the trash can turning mechanism 200 can be reduced and simplified, thereby simplifying the structure and reducing the obstruction of the trash can 200 by the clamping structure during cleaning, thereby improving the cleaning effect.

[0043] Combine Figures 1 to 7According to the limit lock 100 for the trash can turning mechanism 300 of the embodiment of the present invention, the lock hook 10 can be used to connect the trailer handle 21 of the trash can 200. The limit lock 100 includes: a lock hook 10 and a locking member 13. The lock hook 10 is configured to be rotatable between a first position and a second position and has a positioning groove 110. In the first position, the opening of the positioning groove 110 is upward and can be used to hang the trailer handle 21 of the trash can 200; the locking member 13 rotates to connect the lock hook 10. The locking member 13 is configured to move with the lock hook 10 and rotate relative to the locking member 13 under the action of its own weight to lock and unlock the positioning groove 110.

[0044] In one embodiment of the present invention, in the initial state, that is, when the lock hook 10 is in the first position, the opening of the positioning slot 110 is upward, and the trailer handle 21 of the trash can 200 can be hooked in the positioning slot 110 on the lock hook 10. When the trash can turning mechanism 300 turns over, the lock hook 10 rotates along with the trash can turning mechanism 300. When the lock hook 10 rotates from the first position to the second position, the opening direction of the positioning slot 110 gradually changes, for example, from upward to downward. The locking member 13 rotates relative to the lock hook 10 under the action of its own weight. When the positioning slot 110 opens upward, the locking member 13 rotates downward under the action of its own weight, thereby unlocking the positioning slot 110, so that the positioning slot 110 is in an upwardly open state. At this time, the trailer handle 21 can be installed in the positioning slot 110. When the positioning slot opens downward, the locking member 13 rotates downward under the action of its own weight, and the locking member 13 can be opposite to the opening of the positioning slot 110, thereby limiting the trailer handle 21 in the positioning slot 110 and locking the trailer handle 21.

[0045] According to the limit lock 100 of the embodiment of the present invention, the trailer handle 21 of the trash can 200 can be locked during and after the trash can 200 is turned over, thereby improving the stability of the trash can 200 when turning over.

[0046] Combine Figure 3 In some embodiments of the present invention, when the lock hook 10 rotates around the predetermined axis, the locking member 13 rotates under the action of its own weight. During the rotation of the lock hook 10, the locking member 13 can automatically rotate to the direction of gravity based on its own gravity. As a result, the locking member 13 can be automatically unlocked when the positioning slot 110 opens upward, and automatically locked when the positioning slot 110 opens downward. Specifically, Figures 4 to 6 The figure shows the position change of the locking member 13 when the lock hook 10 rotates counterclockwise. Figure 3 , the gravity direction of the locking member 13 is always vertically downward.

[0047] Furthermore, the locking member 13 has a locked state and an unlocked state (see Figure 4 and Figure 6), in the locked state, the locking member 13 is arranged opposite to the positioning groove 110 to lock the positioning groove 110, that is, at least a portion of the locking member 13 can be opposite to the opening of the positioning groove 110, thereby locking the trailer handle 21 in the positioning groove 110. In the unlocked state, the locking member 13 is arranged offset from the positioning groove 110 to unlock the positioning groove 110, so that the opening of the positioning groove 110 can be opened, and the trailer handle 21 can be disengaged from the opening of the positioning groove 110, thereby unlocking the positioning groove 110.

[0048] In some embodiments of the present invention, the locking member 13 is in an unlocked state when the hook 10 is in the first position, and in a locked state when the hook 10 is in the second position. Specifically, when the hook 10 is in the first position, the opening of the positioning slot 110 faces upward, allowing the trailer handle 21 to be received. When the hook 10 is in the second position or rotates from the first position to the second position, the opening direction of the positioning slot 110 changes, and the trailer handle 21 may fall out of the positioning slot 110. Therefore, the locking member 13 is required to lock the positioning slot 110, thereby locking the trailer handle 21. This allows the locking member 13 to effectively lock the trailer handle 21 during the rotation of the hook 10.

[0049] In some embodiments of the present invention, one of the lock hook 10 and the locking member 13 is provided with a limit member, and the other is provided with a matching member. The lock hook 10 also has a third position, and the third position is located between the first position and the second position. In other words, the third position can be the position of the lock hook 10 during the rotation process from the first position to the second position or the position during the rotation process from the second position to the first position. When the lock hook 10 is in the first position, the locking member 13 is in an unlocked state. When the lock hook 10 is in the third position, the locking member 13 is in a locked state. The limit member cooperates with the matching member to limit the rotation of the locking member 13 relative to the lock hook 10, so that the locking member 13 can be maintained in the locked state.

[0050] Specifically, when the hook 10 is in the first position, the opening of the positioning slot 110 is open and facing upward, facilitating the hooking of the trailer handle 21. However, as the hook 10 rotates from the first position to the second position, the opening of the positioning slot 110 changes from the upward position to facing the other direction, potentially causing the trailer handle 21 to slip out of the positioning slot 110. Therefore, to enhance the locking effect, a stopper is provided at the third position. The stopper can limit the locking member 13 to a locked position when the hook 10 rotates to the third position, thereby locking the positioning slot 110 and improving the locking of the trailer handle 21. As the hook 10 continues to rotate from the third position to the second position, the stopper can prevent the locking member 13 from rotating further, maintaining the locked position.

[0051] Combine Figure 1 When the lock hook 10 is in the first position, the opening of the positioning groove 110 is upward, or the initial position of the lock hook 10, at this time, the locking member 13 is in the unlocked state. Figure 7 The second position may be the position where the lock hook 10 has completed flipping, and the locking member 13 is in a locked state. Figure 6 and Figure 14 The third position can be the state during the flipping process of the lock hook 10. This position is between the first position, i.e., the position when the lock hook 10 has not flipped, and the position after the flipping is completed. In the third position, the locking member 13 can be moved to the locked state, which can achieve locking during the flipping process and remain in the locked state.

[0052] Specifically, the locking member 13 can automatically rotate based on the action of gravity when the lock hook 10 rotates. When the locking member 13 follows the lock hook 10 to rotate to the locked state, if the locking member 13 continues to rotate based on the action of gravity, it may not be able to better stop the trailer handle 21. Therefore, the limiter can limit the locking member 13 from continuing to move in the direction of gravity and stably stay in the locked state to improve the locking effect. In this way, when the lock hook 10 continues to rotate, the locking member 13 will no longer follow the lock hook 10 to rotate, and the locking member 13 can be fixedly connected to the lock hook 10.

[0053] For example, combining Figures 5 to 7 In some embodiments of the present invention, the limiting member includes a limiting pin 12 provided on the lock hook 10, and the matching member includes a sliding groove 103 provided on the locking member 13. The limiting pin 12 extends into the sliding groove 103. When the locking member 13 is in the locked state, the limiting pin 12 is located at one end of the sliding groove 103. When the locking member 13 is in the unlocked state, the limiting pin 12 is located at the other end of the sliding groove 103. Specifically, by providing the limiting pin 12 on the lock hook 10 and providing the sliding groove 103 on the locking member 13, the limiting pin 12 can slide within the limiting groove, thereby limiting the range of motion of the locking member 13.

[0054] Combine Figure 4 and Figure 6 The opposite ends of the sliding groove 103 correspond to the locking position 101 and the unlocking position 102 respectively. When the limit pin 12 slides to one end of the sliding groove 103, that is, when the limit pin 12 reaches the locking position 101, the limit pin 12 can limit the rotation of the locking member 13, which is the locking state of the locking member 13. When the limit pin 12 slides to the other end of the sliding groove 103, that is, when the limit pin 12 reaches the unlocking position 102, it is the unlocking state of the locking member 13.

[0055] Alternatively, the limiting member may be a slider provided on the lock hook 10, and the mating member may be a guide rail provided on the locking member 13. When in use, the slider slides within the guide rail, and the opposite ends of the guide rail limit the slider, thereby limiting the position of the locking member 13. Alternatively, the limiting member may be a stopper provided on the lock hook 10, and the mating member may be a convex portion provided on the locking member 13. When the lock hook 10 is in the third position, the stopper stops the convex portion, thereby limiting the position of the locking member 13.

[0056] Furthermore, in some embodiments of the present invention, the sliding groove 103 is configured to be arc-shaped and extend in a direction around the central axis of rotation of the locking member 13. Thus, when the locking member 13 rotates relative to the lock hook 10, the limiting pin 12 on the lock hook 10 can move synchronously within the sliding groove 103, and the locking member 13 can promptly change position according to the rotation of the lock hook 10. Furthermore, the arc-shaped sliding groove 103 provides a smooth sliding path for the limiting pin 12 and relatively uniform force distribution, facilitating rapid response to locking and unlocking of the locking member 13 and improving the reliability of the limit lock 100.

[0057] Specifically, the lock hook 10 is rotatably connected to the locking member 13, and through the cooperation between the sliding groove 103 and the limit pin 12, when the lock hook 10 rotates to a certain extent, when the limit pin 12 reaches one end of the sliding groove 103, that is, the locking position 101, the locking member 13 can be fixed at this position, thereby maintaining the locked state. Therefore, when the lock hook 10 continues to rotate, that is, when the trash can flipping mechanism 300 continues to flip the trash can 200, the locking member 13 can be maintained in the locked state, thereby limiting the trailer handle 21 of the trash can 200 in the positioning groove 110 until the trash can 200 is completely flipped. The locking member 13 can remain in the locked state, and the stability of the trash can 200 during the cleaning process can also be improved.

[0058] After the trash can 200 is cleaned, it needs to be flipped over to a position with the trash can 200 opening facing upwards. The trash can 200 flipping device 33 rotates in the opposite direction, and the lock hook 10 also rotates in the opposite direction. When it rotates to a certain extent, the limit pin 12 begins to slide toward the other end of the sliding groove 103. When the limit pin 12 slides to the other end of the sliding groove 103, that is, the unlocked position 102, the locking member 13 is in the unlocked state, and the lock hook 10 can release the trailer handle 21 to facilitate the removal of the trailer handle 21 and separate the trash can 200 from the limit lock 100. As can be seen, by providing the limit pin 12 and the sliding groove 103 on the limit lock 100 in a coordinated manner, the locking member 13 can be automatically locked and unlocked according to the state of the lock hook 10, without the need for manual control, which helps to reduce manpower, reduce costs, and improve work efficiency.

[0059] Combine Figure 5 and Figure 6In some embodiments of the present invention, the locking member 13 includes a first side portion 131 disposed opposite the positioning slot 110 to lock the positioning slot 110. A second side portion 132 protrudes from the first side portion 131. The second side portion 132 is configured to abut against the trailer handle in the locked state. Thus, when the first side portion 131 fails to lock the positioning slot 110, the second side portion 132 protruding from the first side portion 131 can stop the trailer handle 21, thereby achieving a locking effect and improving the reliability of the position-limiting lock 100. For example, if the sliding slot 103 and the limiting pin 12 fail, the first side portion 132 cannot be positioned in the predetermined locking position. The locking member 13 can continue to rotate, bringing the second side portion 132 closer to the trailer handle 21. The second side portion 132 protruding from the first side portion 131 can cooperate with the trailer handle 21 to achieve the limiting and locking functions, ensuring that the hook 10 and the locking member 13 remain relatively fixed as the hook 10 continues to rotate.

[0060] For example, in the unlocked state, the first side portion 131 is closer to the positioning slot 110 than the second side portion 132. In the locked state, the first side portion 131 is opposite to the positioning slot 110, and can lock the trailer handle 21. The distance L1 between the first side portion 131 and the rotation center axis of the locking member 13 is smaller than the distance L2 between the second side portion 132 and the rotation center axis of the locking member 13. When the first side portion 131 is in the locked state, the first side portion 131 is closer to the positioning groove 110 when the trailer handle 21 is released from the unlocked state. In this way, when the locking member moves from the unlocked state to the locked state, the first side portion 131 can pass through the opening of the positioning groove 110, thereby closing the positioning groove 110 and locking the trailer handle 21 in the positioning groove 110. After the first side portion 131 reaches the locked state, the position of the second side portion 132 also changes accordingly. Since the distance between the second side portion 132 and the rotation center axis is greater than the distance between the first side portion 131 and the rotation center axis, the second side portion 132 can protrude from the first side portion 131. Therefore, the second side portion 132 can limit the trailer handle 21 from other directions, thereby achieving a double locking effect. For example, when the first side portion 131 cannot be stably positioned in the locked state, the trailer handle 21 can also be locked by the second side portion 132, thereby improving the reliability of the limit lock 100.

[0061] Specifically, combined Figure 5In some embodiments of the present invention, the maximum distance L3 between the inner edge of the positioning groove 110 and the central axis of rotation and the maximum width W of the fitting point between the trailer handle 21 and the lock hook 10 satisfy the following conditions: L3 - L1 ≥ W, and L3 - L2 ≤ W. Thus, after the trailer handle 21 is mounted in the mounting groove, the difference between the maximum distance L3 between the inner edge of the positioning groove 110 and the central axis of rotation and the distance L1 between the first side portion 131 and the central axis of rotation of the locking member 13 is greater than or equal to the maximum width W of the fitting point between the lock hook 10. This ensures that the first side portion 131 does not interfere with the trailer handle 21 when moving between the locked and unlocked states. Consequently, the first side portion 131 can lock the trailer handle 21 in the positioning groove 110 in the locked state. The difference between the maximum distance L3 between the inner edge of the positioning groove 110 and the rotation center axis and the distance L2 between the second side portion 132 and the rotation center axis of the locking member 13 is less than or equal to the maximum width W of the lock hook 10 at the fitting position, so that when the second side portion 132 passes through the positioning groove 110, it will interfere with the trailer lock in the positioning groove 110. The second side portion 132 can lock the trailer handle 21 between the positioning groove 110 and the second side portion 132, forming a locking structure.

[0062] Specifically, since the first side portion 131 is closer to the positioning slot 110 than the second side portion 132 in the locked state, when the sliding slot 103 and the limit pin 12 fail, that is, the limit pin 12 cannot position the locking member 13 in the locked state, the first side portion 131 cannot lock the trailer handle 21, and the locking member 13 will continue to rotate. When the second side portion 132 moves to a position close to the opening of the positioning slot 110, the second side portion 132 can directly abut against the trailer handle 21, thereby locking the trailer handle 21, that is, the first side portion 131 and the second side portion 132 of the limit lock 100 can form a double locking structure, which is beneficial to improving the reliability of the limit lock 100.

[0063] Combine Figure 1 In some embodiments of the present invention, the lock hook 10 includes a first connecting portion 111 and a second connecting portion 112. One end of the first connecting portion 111 is connected to one end of the second connecting portion 112 and is configured in a U-shape, which can facilitate the hooking of the trailer handle 21. The U-shaped structure is suitable for cooperating with the cylindrical trailer handle 21. During the rotation of the lock hook 10, the U-shaped structure can cause rolling friction between the trailer handle 21 and the inner wall of the lock hook 10, which is beneficial to protecting the trailer handle 21 and the lock hook 10. The positioning groove 110 is provided between the first connecting portion 111 and the second connecting portion 112, and the locking member 13 is rotatably connected to the other end of the second connecting portion 112. Specifically, the first connecting portion 111 can be used to connect to the trash can flipping mechanism 300, and the second connecting portion 112 can be used to connect to the locking member 13, thereby, the trailer handle 21 can be connected to the trash can flipping mechanism 300 and locked by the locking member 13. More specifically, in combination Figure 1In the first position, the first connecting portion 111 and the second connecting portion 112 are arranged at an angle relative to the vertical direction. In this way, the positioning groove 110 can extend along an angle away from the trash can tilting structure 300, providing space for the installation of the trailer handle 21. In addition, in the initial state, when the limit lock 100 is in the horizontal position, the first connecting portion 111 extends at an angle. This ensures that in the initial position, the locking member 13 and the positioning groove 110 of the lock hook 10 can be misaligned, thereby opening the positioning groove 110 to facilitate the placement and removal of the trailer handle 21.

[0064] Furthermore, the stop pin 12 and the positioning pin 14 extend in the same direction and are spaced apart along the length of the second connecting portion 112. Thus, both the stop pin 12 and the positioning pin 14 can be used to position or limit the locking member 13, facilitating manufacturing and assembly. The spacing between the stop pin 12 and the positioning pin 14 increases the range of the stop pin 12's position on the locking member 13, thereby improving the coordination between the stop pin 12 and the locking member 13.

[0065] In some embodiments of the present invention, the locking member 13 is generally triangular. On the one hand, the triangular locking member 13 can improve the stability of the structure. On the other hand, the triangular locking member 13 has a high space utilization rate and can flexibly adapt to various space layouts. The triangular locking member 13 can reduce the use of materials while providing the same strength, which is conducive to reducing costs. Figure 7 One side of the locking member 13 (ie, the first side portion 131 ) can close the opening of the positioning slot 110 and stop the trailer handle 21 to achieve a locking effect.

[0066] Optionally, the locking member 13 may also be a quadrilateral or polygonal structure.

[0067] The following combination Figures 4 to 7 The rotation of the locking member 13 is described. When the lock hook 10 rotates around the predetermined axis, the locking member 13 moves. Figure 4 When the lock hook 10 rotates, the locking member 13 rotates and automatically moves to a vertical state. Due to the restriction of the sliding groove 103, the locking member 13 is positioned to the unlocked state; as the lock hook 10 continues to rotate in the current direction, the locking member 13 also rotates and automatically rotates toward the direction of gravity. Figure 5 When the locking member 13 rotates in the direction of gravity, the locking member 13 also seals the opening of the positioning slot 110, thereby blocking the trailer handle 21 and locking the trash can 200 during the turning process of the trash can turning mechanism 300. In other words, when the locking member 13 is in a state between the locked state and the unlocked state, it can also play a certain locking and limiting role on the trailer handle 21. Figure 6When the degree of the turning of the trash can turning mechanism 300 gradually increases and the rotation angle of the lock hook 10 gradually increases, the locking member 13 moves toward the direction of gravity and automatically reaches the locked state. The locking member 13 is limited by the position limiting member and can remain in the locked state until the trash can 200 is completely turned over. Figure 7 That is to say, when the flipping angle of the trash can flipping mechanism 300 becomes larger, the locking member 13 will automatically move to the locked state. The locking member 13 can lock the trash can 200 during the flipping process to improve the reliability of the flipping, and can also continue to lock the trash can 200 after the trash can 200 is flipped, thereby keeping the trash can 200 stable during the cleaning process.

[0068] It should be noted that, combined with Figure 8 and Figure 9 The trash can 200 extends in the vertical direction, wherein the trash can 200 includes a barrel body 20 and a barrel cover 22. The barrel body 20 is provided with a trailer handle 21 on both sides of the upper portion. The top of the barrel body 20 has an opening, and the barrel cover 22 can be opened and closed. The trash can 200 opens upward in the normal state, and opens downward after being turned over, so that a cleaning device can be inserted into the barrel body 20 to clean the inner wall of the barrel body 20. Figure 13 Shows the normal state of the trash can 200, such as Figure 14 The state of the trash can 200 during the flipping process is shown in FIG. Figure 15 FIG2 shows the state after the trash can 200 is turned over. Figure 14 You can read that during the reversal of the trash can 200, the locking member 13 can be rotated to the locked state to lock the trash can 200, thereby preventing the trash can 200 from falling during the reversal. Similarly, when the trash can 200 is rotated from the reversal state to the normal state, that is, after cleaning, when the trash can 200 is restored to the state with the trash can 200 opening facing upward, the locking member 13 can also move in the direction of gravity due to its own gravity during the rotation process, thereby automatically rotating the locking member 13 from the locked state to the unlocked state, thereby unlocking the trash can 200 and facilitating the removal of the trash can 200.

[0069] Combine Figure 5In some embodiments of the present invention, the locking member 13 has a second side portion 132, which is adapted to position the locking member 13 in a locked state. In the locked state, the locking member 13 closes the positioning slot 110. In combination with the foregoing, the second side portion 132 protrudes from the main body of the locking member 13, and the first side portion 131 and the second side portion 132 form an "L"-shaped stop structure at the bottom of the locking member 13. When the sliding slot 103 and the limit pin 12 fail, that is, when the limit pin 12 cannot limit the locking member 13 in the locked state, the locking member 13 can continue to rotate to the locked state, so that the second side portion 132 abuts the trailer handle 21. In this way, the first side portion 131 can cover the opening of the positioning slot 110, and the second side portion 132 can abut the trailer handle 21. In other words, the first side portion 131 and the second side portion 132 can jointly lock the trailer handle 21 in the positioning slot 110.

[0070] Combine Figure 2 In some embodiments of the present invention, the lock hook 10 is provided with a positioning pin 14, and the locking member 13 has a positioning hole 104. The positioning pin 14 passes through the positioning hole 104 and is fixed by a locking nut 15, thereby realizing the rotational connection between the lock hook 10 and the locking member 13.

[0071] The lock hook 10 or the second connecting portion 112 of the lock hook 10 also has a positioning seat 141. The positioning pin 14 is located on the positioning seat 141 and extends away from the lock hook 10. The positioning seat 141 supports the positioning pin 14 and also separates the locking member 13 from the lock hook 10, providing space for the locking member 13 to move. The cross-sectional area of ​​the positioning seat 141 is larger than that of the positioning pin 14. During assembly, the positioning hole 104 of the locking member 13 passes through the positioning pin 14 and abuts against the positioning seat 141, thereby improving structural stability.

[0072] In some embodiments of the present invention, the locking member 13 is fixed by a locking nut 15, and a pressure plate 16 is provided between the locking member 13 and the locking nut 15. The cross-sectional area of ​​the pressure plate 16 is larger than the cross-sectional area of ​​the locking nut 15 and the cross-sectional area of ​​the positioning hole 104, which can increase the contact area between the locking nut 15 and the locking member 13 and improve the structural stability after locking.

[0073] In some embodiments of the present invention, a locking washer 17 is provided between the locking member 13 and the locking nut 15. The cross-sectional area of ​​the locking washer 17 is larger than the cross-sectional area of ​​the locking nut 15 and the cross-sectional area of ​​the positioning hole 104, which can increase the contact area between the locking nut 15 and the locking member 13, facilitate pressure dispersion, protect the surface of the locking member 13, increase friction, and improve the structural stability after locking.

[0074] In some embodiments of the present invention, the cross-sectional area of ​​the pressure plate 16 is larger than the cross-sectional area of ​​the locking washer 17, so that the locking washer 17 can be completely pressed against the pressure plate 16, which is beneficial to improving the assembly stability, and the pressure block 324 and the locking washer 17 are provided at the connection position to form a multi-layer structure, which is beneficial to improving the structural stability of the locking position.

[0075] Combine Figures 1 to 15 The trash can flipping mechanism 300 according to an embodiment of the present invention includes: a mounting base 31, a clamping portion 32, and the aforementioned limit lock 100. The clamping portion 32 is rotatably connected to the mounting base 31, and the lock hook 10 is connected to the clamping portion 32. Specifically, the clamping portion 32 can clamp the body 20 of the trash can 200. The limit lock 100 can then attach the trash trailer handle 21 after the clamping portion 32 clamps the trash can 200. The flipping device 33 of the trash can flipping mechanism 300 can drive the clamping portion 32 to rotate relative to the mounting base 31, thereby flipping the trash can 200.

[0076] According to the trash can turning mechanism 300 of the embodiment of the present invention, by providing the aforementioned limit lock 100, the trash can 200 can be locked during and after the turning of the trash can 200, so as to improve the turning stability of the trash can 200.

[0077] In some embodiments of the present invention, Figure 13 and Figure 14 The clamping portion 32 has a barrel hanging position and a dumping position. The locking member 13 is in an unlocked state in the barrel hanging position and in a locked state in the dumping position. Figure 11 and Figure 12 The hanging position of the trash can is shown, that is, the locking member 13 of the limit lock 100 is misaligned with the positioning groove 110, so that the limit groove is open and the locking member 13 is in the unlocked state, and the trailer handle 21 of the trash can 200 can be hung in the positioning groove 110. Figure 14 and Figure 15 The tipping position is shown, that is, the locking member 13 of the limit lock 100 is in a locked state, and the locking member 13 covers the opening of the positioning groove 110, so that the trailer handle 21 can be locked between the positioning groove 110 and the locking member 13.

[0078] In some embodiments of the present invention, the lock hook 10 includes a first connecting portion 111 and a second connecting portion 112. The first connecting portion 111 and the second connecting portion 112 are connected and configured in a U shape to facilitate the hooking of a circular trailer handle 21, and the trailer handle 21 can rotate during the flipping process of the trash can 200. The positioning groove 110 is provided between the first connecting portion 111 and the second connecting portion 112. The first connecting portion 111 is closer to the clamping portion 32 than the second connecting portion 112. The first connecting portion 111 is connected to the clamping portion 32, and the locking member 13 is rotatably connected to the second connecting portion 112, so that the limit lock 100 can be connected to the clamping portion 32.

[0079] In some embodiments of the present invention, the positioning groove 110 is configured to open upward at the barrel hanging position, and the second connecting portion 112 is configured to extend in the up-down direction and tilt upward in the direction away from the first connecting portion 111 in the extending direction from bottom to top.

[0080] Specifically, combined Figure 4 In some embodiments of the present invention, the clamping portion 32 has a clamping state and an open state. The clamping portion 32 includes a first clamp 321, a second clamp 322, and a driving member 323. The first clamp 321 and the second clamp 322 are at least partially opposed to each other in the vertical direction. The driving member 323 is connected to the first clamp 321 and / or the second clamp 322 and drives the first clamp 321 and / or the second clamp 322 to move in the vertical direction. Thus, the driving member 323 can drive the first clamp 321 to move toward the second clamp 322 to clamp the trash can 200 between the first clamp 321 and the second clamp 322, or the driving member 323 drives the second clamp 322 to move toward the first clamp 321 to achieve clamping. Alternatively, the driving member 323 can drive the first clamp 321 and the second clamp 322 to move simultaneously to achieve clamping.

[0081] Furthermore, the first clamp 321 extends in the front-to-back direction, one end of the first clamp 321 is provided with a hook 325, and the other end is provided with a limit lock 100, the hook 325 can be used to hang the periphery of the trash can 200, combined with Figure 13 Through the cooperation of the hook 325 and the limit lock 100, the front and rear ends of the trash can 200 are fixedly connected to the clamping part 32 in the front-to-back direction, which is conducive to improving the stability during flipping.

[0082] Furthermore, the second clamp 322 is provided with a pressing block 324, and the pressing block 324 and the first clamp 321 clamp the trash can 200, and the Figure 13 and Figure 14 The pressing block 324 can abut against the trash can 200, which is beneficial to improving the stability after clamping. Among them, the pressing block 324 can be made of a material with flexibility or high friction, which can improve the clamping effect and prevent the trash can 200 from sliding or falling off.

[0083] According to an embodiment of the present invention, the trash can 200 cleaning vehicle includes: a vehicle body 400 and the aforementioned trash can flipping mechanism 300, wherein the vehicle body 400 has a cleaning chamber 500; the trash can flipping mechanism 300 is rotatably connected to the vehicle body 400; the flipping mechanism is suitable for flipping the trash can 200 from the outside of the vehicle body 400 to the cleaning chamber 500.

[0084] According to the garbage can 200 cleaning vehicle of the embodiment of the present invention, by setting the aforementioned garbage can flipping mechanism 300, the garbage can 200 can be flipped from the outside of the garbage can 200 cleaning vehicle to the inside of the garbage can 200 cleaning vehicle, and the opening of the garbage can 200 after flipping is downward, which is convenient for cleaning. The limit lock 100 of the garbage can flipping mechanism 300 can improve the stability of the garbage can 200 during flipping, and during cleaning, the structure of the garbage can flipping mechanism 300 is simple, and the obstruction to the garbage can 200 is small, which is conducive to improving the cleaning effect.

[0085] The following describes a trash can 200 cleaning vehicle, a trash can turning mechanism 300 and a limit lock 100 according to a specific embodiment of the present invention with reference to the accompanying drawings.

[0086] With the advancement of society and the increasing demands placed on the urban environment, a trash can cleaning vehicle for cleaning municipal and kitchen waste bins has emerged. To this end, the present invention provides a limit lock 100 for a trash can tilting mechanism 300. This limit lock 100 utilizes the principle that gravity always forces the force vertically downward. During operation, the lock plate rotates, locking the trash can 200. This stabilizes the trash can 200 in the desired position, facilitating 360° cleaning of the trash can 200 by the cleaning equipment.

[0087] Combine Figures 1 to 15 The garbage bin 200 cleaning vehicle includes a power cabin 800, a clean water tank 600, a sewage tank 700, a cleaning chamber and a garbage bin turning mechanism 300. When used, combined with Figures 11 to 15 , manually push the trash can 200 into place, lift the driving member 323 to lift the first clamp 321 upward, the hook 325 hooks the edge of the trash can 200, the trash can 200 trailer handle 21 is hooked to the lock hook 10 of the limit lock 100, and the entire trash can 200 is lifted upward until the bucket mouth reaches the pressing block 324. At this time, the pressing block 324 and the hook 325 or the first clamp 321 and the second clamp 322 clamp the trash can 200. Figure 13 Next, under the vehicle control command, the turning device 33 of the trash can turning mechanism 300 is about to turn over, and the trash can 200 is about to enter the cleaning room, as shown in FIG. Figure 14 .

[0088] The working principle of the limit lock 100 is described in detail below.

[0089] The locking member 13 is loosely fitted with the positioning pin 14. The pressure plate 16 is pressed on the step formed by the positioning pin 14 and the positioning seat 141 and is locked with the lock nut 15. The locking member 13 can rotate around the positioning pin 14. The limit pin 12 extends into the sliding groove 103 of the locking member 13 and slides in the sliding groove 103 to limit the rotation range of the locking member 13. When the trash can turning mechanism 300 together with the clamping part 32 turns the trash can 200 into the cleaning chamber, as shown in FIG. Figure 4 , the lock hook 10 rotates counterclockwise.

[0090] According to the calculation formula of gravity in physics:

[0091] G=mg

[0092] In this formula,

[0093] G represents the gravity acting on the object

[0094] m represents the mass of the object

[0095] g is the acceleration due to gravity, approximately equal to 9.8N / kg

[0096] The direction of gravity is always vertically downward (see gravity force analysis Figure 3 ).

[0097] Then: Combine Figure 3 and Figure 4 When the trash can turning mechanism 300 starts to rotate counterclockwise, the locking member 13 moves in translation with the positioning pin 14 as the fulcrum under the action of gravity in the vertical downward direction; then, the clamping portion 32 continues to rotate counterclockwise (as shown in FIG. Figure 5 ), until the limit pin 12 rests against the limit position of the lock plate (such as Figure 6 ), from this moment on, the locking member 13 rotates counterclockwise along with the clamping portion 32, and synchronously, the trash can 200 falls slightly under the force of gravity and is locked by the locking member 13 (such as Figure 7 ), the process of the trash can 200 being locked by the lock plate does not require manual operation, nor does it require additional complex mechanical mechanisms. The structure is simple, can be automatically adjusted and has strong reliability. The trash can 200 is turned upside down in a predetermined position in the cleaning room, waiting for cleaning (such as Figure 15 ). When the trash can 200 is cleaned, it can be flipped back to its initial state, that is, rotated clockwise.

[0098] Specifically, in actual use, under the control of the intelligent control system, after the trash can 200 is cleaned, the system mechanism performs a reciprocating motion, and the locking member 13 is opened by gravity, without the need for additional manual operation. The system then returns the trash can 200 to its initial position, and a human operator moves the trash can 200 to a designated location. The entire process takes approximately two minutes, and the total cost is half of the labor cost.
