[0001] This utility model relates to the field of flexible shaft controller technology, specifically a hydraulic control controller. Background Technology

[0002] The multi-way valve of a tractor is a core control component of the hydraulic system. It is mainly used to control the flow of hydraulic oil and realize key functions such as lifting agricultural implements and hydraulic output.

[0003] The mechanical hydraulic control levers of existing tractors are usually located on both sides of the seat. Whether the hydraulic control levers are stamped and welded or molded, they do not have fixed-point limit and self-resetting functions. This means that the operator has to hold the control lever at all times, which cannot free up their hands. Prolonged operation can easily lead to fatigue and increase the labor intensity of the operator. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a hydraulic control controller that is easy and labor-saving to operate, with locking and self-resetting functions, making it convenient for operators to use and effectively solving the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic control controller, comprising a first housing and a second housing fixedly connected to each other, the interior of the first housing and the second housing being a cavity structure, a rocker arm being disposed in the cavity of the first housing and the second housing, the upper end of the rocker arm being connected to a handle rod, the upper end of the handle rod being provided with a handle ball, one end of the rocker arm being connected to a flexible shaft connector, and a rotatable locking member being disposed at the upper end of the first housing and the second housing, the locking member locking and limiting the handle rod.

[0006] As a preferred embodiment of this utility model, the locking component includes a disc, a connecting ring, and a rib plate. The disc and the connecting ring are arranged opposite to each other, and the rib plate is symmetrically fixed between the disc and the connecting ring. The disc is located on one side of the upper end of the first housing and the second housing, and the connecting ring is located on the other side of the upper end of the first housing and the second housing. The rib plate and the connecting ring are rotatably connected to the connection between the first housing and the second housing. One of the rib plates is provided with multiple slots that match the outer dimensions of the handle rod.

[0007] As a preferred embodiment of this utility model, three stop grooves are evenly distributed on the lower end of the outer side of the connecting ring, and a nylon limiting strip is provided below the connecting ring. The nylon limiting strip is disposed in the internal cavity of the first housing and the second housing. The nylon limiting strip is elastic, and the protrusion at the upper end of the nylon limiting strip is adapted to the size of the stop groove.

[0008] As a preferred embodiment of this utility model, the disc is located outside the first housing and the second housing, and a rotating handle is fixed to the outer surface of the disc.

[0009] As a preferred embodiment of this utility model, a torsion spring is provided in the internal cavity of the first housing and the second housing, and one end of the torsion spring is connected to the rocker arm.

[0010] As a preferred embodiment of this utility model, a baffle is connected to one side of the lower end of the handle rod. The baffle is made of nylon, and its width is adapted to the width of the internal cavity of the first and second housings.

[0017] 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 (for ease of description and understanding, hereinafter referred to as...). Figure 1 (The above is described above). Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Please see Figure 1-3 This utility model provides a technical solution: a hydraulic control controller, including a first housing 3 and a second housing 4 that are fixedly connected. The first housing 3 and the second housing 4 are connected by screws 8. After the first housing 3 and the second housing 4 are connected, a cavity is formed inside. A flexible shaft connector 5 and a rocker arm 10 are both disposed in the cavity. The upper end of the rocker arm 10 is connected to a handle rod 2. A handle ball 1 is provided at the upper end of the handle rod 2. One end of the rocker arm 10 is connected to the flexible shaft connector 5. The end of the flexible shaft connector 5 extends out of the housing and connects to the flexible shaft. By controlling the swing of the handle rod 2, the rocker arm 10 is driven to swing, thereby realizing the extension and retraction control of the flexible shaft connected to the flexible shaft connector 5, thereby driving the hydraulic multi-way valve of the tractor to operate.

[0019] The upper ends of the first housing 3 and the second housing 4 are provided with rotatable locking components 6. The locking components 6 include a disc 61, a connecting ring 62, and a rib 63. The disc 61 and the connecting ring 62 are arranged opposite to each other. The rib 63 is symmetrically fixed between the disc 61 and the connecting ring 62. The disc 61 is located on one side of the upper end of the first housing 3 and the second housing 4 and is located on the outside of the housing. The connecting ring 62 is located on the other side of the upper end of the first housing 3 and the second housing 4. One end of the rib 63 near the disc 61 is rotatably connected to the connection position of the first housing 3 and the second housing 4. The connecting ring 62 is rotatably connected to the connection position of the first housing 3 and the second housing 4. One of the ribs 63 is provided with multiple slots 64 that match the outer dimensions of the handle rod 2. When it is necessary to limit the handle rod 2, the disc 61 is rotated to drive the rib 63 and the connecting ring 62 to rotate together, so that the slots 64 on the rib 63 lock the handle rod 2 and prevent it from moving. This achieves fixed-point limiting of the end load, freeing up the hands and avoiding fatigue operation.

[0020] To limit the locking component 6, three stop grooves 66 are evenly distributed on the lower end of the outer side of the connecting ring 62. A nylon limiting strip 11 is provided below the connecting ring 62. The nylon limiting strip 11 is set in the internal cavity of the first housing 3 and the second housing 4. The nylon limiting strip 11 is elastic. The protrusion at the upper end of the nylon limiting strip 11 is adapted to the size of the stop groove 66. When the locking component 6 rotates and limits the handle rod 2, the stop groove 66 at the lower end of the connecting ring 62 will be locked in the protrusion at the upper end of the nylon limiting strip 11, ensuring that the locking component 6 will not rotate circumferentially.

[0021] To facilitate operator control of the rotation of the disc 61, a rotating handle 65 is fixed to the outer side of the disc 61.

[0022] In order to realize the self-resetting function of the handle lever 2, a torsion spring 9 is provided in the internal cavity of the first housing 3 and the second housing 4. One end of the torsion spring 9 is connected to the rocker arm 10. When the rocker arm 10 swings, it drives the torsion spring 9 to be stressed. When the locking member 6 is unlocked, the handle lever 2 automatically resets, thereby releasing the control of the end hydraulic system.

[0023] To achieve a dustproof effect, a baffle 7 is connected to one side of the lower end of the handle 2. The baffle 7 is made of nylon, and its width is adapted to the width of the internal cavity of the first housing 3 and the second housing 4.

[0024] In use: When it is necessary to control the operation of the tractor hydraulic multi-way valve, push the handle lever 2 to drive the rocker arm 10 to swing, thereby causing the flexible shaft connected to the flexible shaft joint 5 to extend or retract, thus controlling the operation of the hydraulic multi-way valve; when it is necessary to keep the hydraulic multi-way valve operating continuously, the handle lever 2 needs to be kept stationary. At this time, by rotating the disc 61 of the rotating locking part 6, the rib plate 63 and the connecting ring 62 will rotate together. At this time, the slot 64 on the rib plate 63 will lock the rod of the handle lever 2 so that it cannot move. At the same time, the stop groove 66 at the lower end of the connecting ring 62 will be correspondingly locked by the nylon limit strip 11, thereby ensuring the locking effect of the locking part 6.

[0025] When a reset is required, simply rotate the locking element 6 in the opposite direction. Under the restoring force of the torsion spring 9, the handle rod 2 will be reset, releasing the operation control of the end hydraulic multi-way valve.
