[0048] The specific implementation methods of the present application are further described in detail below with reference to the accompanying drawings.

[0049] See also Figure 1 and Figure 5 The present application provides a self-locking structure 10 for connecting or separating a first target part 20 and a second target part 30, comprising:

[0050] The fixing part 11 includes a slide rail 111 disposed on the first target part 20 and a guide member 112 disposed on the slide rail 111 and capable of sliding up and down relative to the slide rail 111. The guide member 112 is provided with a clamping part 113 for clamping the second target part 30.

[0051] The handle 12 includes a supporting portion 121 and a handle portion 122. The supporting portion 121 is pivotally connected to the first target member 20 and one end thereof abuts against the guide member 112. The handle portion 122 is operated to rotate the supporting portion 121 relative to the first target member 20 and drive the guide member 112 to slide up and down along the slide rail 111, so that the clamping portion 113 is separated from the second target member 30 or is self-lockingly fixedly connected.

[0052] The limiting portion 13 is used to limit the handle portion 122 .

[0053] When in use, the self-locking structure 10 is controlled by the handle 12 to switch between the self-locking state and the unlocking state. Figure 1 and Figure 3When the self-locking structure 10 is in the self-locking state, the handle portion 122 of the handle 12 abuts against the second limiting portion 13, and the abutting portion 121 abuts against the inner upper portion of the guide member 112. At this time, although the movable portion applies a downward force to the abutting portion 121 through the guide member 112, the vertical upward force applied by the limiting portion 13 to the handle portion 122 and the force of the first target member 20 on the handle 12 together make the handle 12 and the guide member 112 in a self-locking state with balanced forces, thereby achieving stable fit between the second target member 30 and the first target member 20. When unlocking is required, the handle portion 122 is pulled upward, the handle 12 rotates, and the abutting portion 121 drives the guide member 112 to move downward. At this time, the guide member 112 and the handle 12 are no longer in the self-locking state, and the second target member 30 is separated from the first target member 20 under the action of gravity, and the self-locking structure 10 enters the unlocking state. Figure 2 and Figure 4 In this embodiment, the limiting portion 13 is disposed on the side of the slide rail 111 , and the limiting portion 13 can also be disposed on the fixing portion 11 or other positions to limit the handle 12 .

[0054] In one embodiment, the abutting portion 121 abuts against the guide member 112 via a pulley 123. One end of the abutting portion 121 is pivotally connected to the pulley 123, and the pulley 123 penetrates into the guide member 112 and abuts against the inner edge of the guide member 112 from the side. The use of the pulley 123 can reduce the friction between the edge of the guide member 112 and the abutting portion 121, which helps to reduce the force applied by the operator during use and improves ease of use. A slider can also be used to achieve the abutment between the abutting portion 121 and the guide member 112.

[0055] In one embodiment, the guide member 112 is a hollow frame, and the abutting portion 121 abuts the guide member 112 through the inner side of the frame, and drives the guide member 112 to move in the vertical direction through its own rotation. The abutting portion 121 abuts against the guide member 112 in the hollow interior of the frame, making the force of the entire guide member 112 more uniform and balanced, while also reducing the space occupied by the self-locking structure 10, making the structure of the entire mechanism more concise.

[0056] In one embodiment, the slide rail 111 is a strip-shaped component with a slide groove on one side, and the slide groove is used to accommodate and guide the guide member 112. In this embodiment, the slide rails 111 are arranged in pairs on the first target member 20, and the slide grooves of the two slide rails 111 are arranged in opposite directions, and the guide member 112 is clamped therein. Each slide rail 111 is arranged on opposite sides of the guide member 112, and the guide member 112 is respectively accommodated in the slide groove, so that the guide member 112 is clamped between the two slide rails 111, so that the force on the guide member 112 is more uniform, and it is not easy to be dislocated or derailed, so that the state of the self-locking structure 10 is more stable during the movement.

[0057] See also Figure 6and Figure 7 The present application provides a box 100 for collecting materials leaked from the device, including an upper box, a lower box and the self-locking structure 10 as described above, the upper box is the first target part 20, and the lower box is the second target part 30. The box 100 in this embodiment is a dust collecting box used in seedling pot production equipment, which is used to store materials leaked by the suction device during the process of sucking the matrix, such as the matrix, to avoid clogging the suction air duct. During use, the upper box and the lower box are sealed by the self-locking structure 10. When the lower box is full, the self-locking device can be switched to the unlocked state by pushing the handle 12 upwards to separate the upper and lower boxes. At this time, the lower box is removed to facilitate cleaning of the materials stored in the lower box, such as Figure 8 When it is necessary to reinstall, the lower box body is reinstalled to the original position, and then the handle 12 is pressed down to switch the self-locking device to the self-locking state. At this time, the upper and lower boxes are stably fitted under the action of the self-locking device.

[0058] In one embodiment, the lower box body is provided with a protrusion 31 that is hooked with the clamping portion 113. The guide member 112 is hooked with the protrusion 31 of the second target member 30 through the clamping portion 113, thereby applying a vertical force to the second target member 30. In this embodiment, the clamping portion 113 and the protrusion 31 can be flat keys that protrude and hook with each other.

[0059] In one embodiment, a notch 114 is provided at one end of the slide rail 111 close to the second target part 30, and the protrusion 31 passes through the notch 114 when the second target part 30 is disassembled. In this embodiment, a notch 114 is provided below the slide rail 111 close to the handle 12, and the shape and size of the notch 114 are larger than the protrusion 31. The second target part 30 and the first target part 20 achieve relative up and down displacement under the guidance of the guide member 112 and the slide rail 111, so it is beneficial to save space to remove the second target part 30 from the front and back direction. Therefore, a notch 114 is provided on the slide rail 111 for the protrusion 31 to pass through it and the second target part 30 is pulled out, so that the second target part 30 can be removed from the front and back direction, thereby reducing the space occupied by the self-locking mechanism in the unlocked state.

[0060] In one embodiment, the lower box body is provided with a gripper 32 for dragging the lower box body. Since the seedling pot production equipment is usually compact in layout, the dust collecting box is generally arranged at the bottom with a relatively narrow space, and the gripper 32 can effectively improve the convenience during the disassembly and assembly process.

[0061] Please continue reading Figure 8In one embodiment, the lower box body is provided with a positioning plate 33, which is against the side of the upper box body and is used for positioning when installing the lower box body. Since the dust collecting box is usually arranged at the bottom of the seedling pot production equipment, the space is small and inconvenient to operate, and it is also inconvenient to observe whether it is reinstalled in place, so the positioning plate 33 is provided to simplify the positioning method. When reinstalling the lower box body, it can be judged whether the lower box body is reinstalled in place by whether the positioning plate 33 contacts the upper box body, which improves the convenience during use. The positioning plate 33 can be arranged at one end of the lower box body and is a plate-shaped protruding upward.

[0062] In one embodiment, a sealing strip is provided at the contact point between the lower box and the upper box to improve the sealing performance of the box 100 when it is self-locking. The sealing strip can improve the sealing performance of the box 100 when it is installed and prevent the internal material from leaking out. An elastic sealing strip can be used to improve the convenience during use, reduce wear and tear, and reduce the pressure of equipment maintenance. A sealing strip of universal specifications can be used to reduce spare parts requirements and maintenance pressure.
