Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Specific Implementation Example 1: Please see Figure 1-9 As shown, this utility model is a quick-connect anti-detachment hook for agricultural machinery, designed to solve the problems of inconvenient and time-consuming traditional manual installation of pins when connecting tractors and trailers. The hook includes a connecting seat 1, a pin 2, a pin actuating shaft 3, a handle 4, a locking spring 5, a limiting baffle 6, a locking push slider 7, and a cover plate 8.

[0029] The pin-driven shaft 3 and the pin 2 are connected by a sliding guide drive, enabling the pin 2 to move up and down. The top of the connecting seat 1 has a device compartment 11 for installing various components; the lower front half has a horizontally positioned C-shaped quick-connect hole 12 for inserting the connector of the device to be connected. An arc-shaped slide rail 13 is provided between the device compartment 11 and the C-shaped quick-connect hole 12, which cooperates with the locking push slider 7 to ensure smooth movement of the locking push slider 7. The bottom of the device compartment 11 has a pin hole 14 that slides through the pin 2, allowing the pin 2 to slide up and down. The two side walls of the device compartment 11 have first through holes 15 for rotatably mounting the pin-driven shaft 3, allowing the pin-driven shaft 3 to rotate freely within them. A handle 4 is installed at each end of the pin-driven shaft 3 on the outer side of the device compartment 11 for easy gripping and rotation by the operator. The equipment compartment 11 has second through holes 16 on both side walls. Two limiting baffles 6 are installed inside the equipment compartment 11 through round shafts 9 installed on the second through holes 16. Torsion springs 10 are installed on the round shafts 9 to flip the two limiting baffles 6, so as to realize the automatic reset of the limiting baffles 6. Two positioning seats 17 for limiting the limiting baffles 6 are symmetrically fixed on the inner walls of both sides of the equipment compartment 11 to ensure the accurate position of the limiting baffles 6. A locking spring 5 is installed between the pin actuating shaft 3 and the rear wall of the equipment compartment 11 to provide tension so that the pin actuating shaft 3 tends to rotate. A cover plate 8 is installed on the upper end of the equipment compartment 11 to protect the internal components from external interference.

[0030] Working principle: Before use, the operator holds both handles 4 and lifts them upwards. At this time, the lever 35 on the pin actuating shaft 3 pushes the limit baffle 62 of the limiting baffle 6 forward and over the baffle 62. Subsequently, the limiting baffle 6 returns to its original position under the action of the torsion spring 10, blocking the lever 35 and preventing it from rotating in the opposite direction. At the same time, the pin 2 moves upward into place under the push of the pin actuating shaft 3, completing the lifting process of the pin 2.

[0031] During quick connection of agricultural machinery, the connector of the equipment to be connected is inserted into the C-shaped quick-connect hole 12. The connector impacts the locking push slider 7, and the arc-shaped push rod 72 at the front end of the locking push slider 7 pushes against the limit baffle 62 and flips forward, causing the lever 35 to disengage from the limit baffle 6. At this time, the pin actuating shaft 3 rotates rapidly under the tension of the locking spring 5, driving the pin 2 to be quickly pushed down and inserted into the hole of the connector, realizing the quick connection of the agricultural machinery. At the same time, under the continuous action of the locking spring 5, the pin 2 is effectively prevented from moving upward and disengaging, thus achieving the anti-disengagement function.

[0032] The rear end of the connecting seat 1 is fixed with a mounting flange plate 18, which makes it easy to fix the hook to the agricultural machinery.

[0033] The upper end of the pin 2 has a rectangular channel 21 that runs through the axis. The two walls of the rectangular channel 21 have cylindrical pin mounting holes 22. A cylindrical pin is installed between the two cylindrical pin mounting holes 22 for connection and guidance with the pin actuating shaft 3.

[0034] The main body of the pin-driven shaft 3 is a cylindrical rod 31, with a connecting rod 32 fixed in the middle and arranged radially therein. A cylindrical pin passes through the cylindrical pin through the cylindrical pin through the cylindrical pin 33 to achieve sliding guide drive.

[0035] A rectangular positioning groove 34 is opened at each end of the cylindrical rod 31 along the axial direction. Two lever plates 35 are fixed on the outer wall, which are symmetrically arranged with respect to the connecting rod body 32. A guide hook 36 is provided on the side of the lever plate 35 adjacent to the pin 2. The first single lug 37 connected to the locking spring 5 is fixed in the middle of the outer wall.

[0036] The handle 4 includes a circular sleeve 41 connected to the end of the cylindrical rod 31. A tangent handle plate 42 is fixed on the outer wall of the circular sleeve 41 for easy gripping. A rectangular protrusion 43 that mates with the rectangular positioning groove 34 is fixed on the inner wall of the circular sleeve 41 to ensure synchronous rotation of the handle 4 and the pin actuation shaft 3.

[0037] The limiting baffle 6 includes a cylinder 61 sleeved on the round shaft 9, and a baffle 62 fixed on the outer wall of the cylinder 61 along its axial direction to prevent the reverse rotation of the lever 35.

[0038] The locking push slider 7 includes an arc slider 71 that mates with the arc slide rail 13. The lower end of the arc slider 71 is set as an arc surface, and two arc push rods 72 are symmetrically fixed at the upper end to ensure accurate impact and push with the connector plug. The inner arc surface of the arc push rod 72 is fixed with a limit protrusion 73 to ensure that the locking push slider 7 will not slide out and detach from the connector seat 1.

[0039] One specific application of this embodiment is: in farmland operations, when it is necessary to quickly connect a tractor to a trailer or other equipment, the operator only needs to operate according to the above working principle to achieve a fast and safe connection of the agricultural machinery, which greatly improves the efficiency of the operation.
