Description

Technical Field

[0001] This utility model relates to the field of directional valve technology, specifically to a manual directional valve handle structure. Background Technology

[0002] A manual directional valve is a control valve in a fluid power system (hydraulic or pneumatic system) that changes the direction of fluid (oil or air) flow through manual operation.

[0003] Its core function is to control the direction of movement of actuators (such as hydraulic cylinders, air cylinders, hydraulic motors, and pneumatic motors), for example, to extend or retract the hydraulic cylinder, or to make the motor rotate forward or backward.

[0004] For example, Chinese Patent Publication No. CN222864211U discloses a manual directional valve, including a valve body. A first valve core is movably connected to the upper end of the valve body, and a second valve core is movably connected to the lower end of the valve body. A connecting rod is located at the center of the top of the second valve core, and the top of the connecting rod is connected to the bottom of the first valve core. A first liquid outlet is located at the upper end of the valve body surface, with one end extending into the interior of the valve body. A second liquid outlet is located on the valve body surface below the first liquid outlet. A first fluid delivery chamber is located inside the first valve core, and a second fluid delivery chamber is located inside the second valve core. A first supply port is located on the outer wall of one side of the valve body. This invention not only realizes the dual-channel fluid delivery function of the directional valve but also enables dual-position fluid delivery control, improving the fluid delivery efficiency during use. Furthermore, it reduces leakage during fluid delivery, improving the sealing performance of the directional valve.

[0005] Existing manual directional valves, such as those in the aforementioned patent, typically have a one-piece handle on the valve body. The handle is quite long, which results in a significant space requirement during transportation or use.

[0006] Therefore, the applicant has made beneficial designs and found a way to solve the above problems. The technical solution to be introduced below is generated in this context. Utility Model Content

[0007] The present invention provides a manual directional valve handle structure to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A manual directional valve handle structure includes a valve body and a handle. The valve body has a connecting rod at its top. The handle includes a first handle and a second handle hinged to the first handle. A connecting hole is formed on one end surface of the first handle, and the connecting rod is inserted into the connecting hole. A slot is formed on one side of the first handle, and a locking block is formed on one side of the second handle to fit the slot. A fixing hole is formed on the surface of the locking block. A through hole is formed on the surface of the first handle through the slot, and a fixing pin is provided in the through hole. A magnet is formed on one side of the first handle, and a magnet is formed on one side of the second handle to fit the magnet. The locking block is inserted into the slot, and the fixing pin is inserted into the fixing hole.

[0010] Preferably, the handle is covered with a rubber sleeve, and one side of the rubber sleeve has an opening that cooperates with the magnet.

[0011] Preferably, a connecting groove is provided on the same side of the first handle and the second handle, and a hinge is provided in the connecting groove.

[0012] Preferably, the hinge is located on the same side as the first magnet and the second magnet.

[0013] Beneficial effects

[0014] The above-mentioned technical solutions in the manual reversing valve handle structure provided by this utility model embodiment have at least one of the following technical effects:

[0015] Through the above-described technical solution, this utility model allows for easy operation during transportation or after the directional valve has been operated. By pulling the fixing pin out of the fixing hole and rotating the second handle towards the first handle, the second handle and the first handle can be rotated and folded together, changing the handle shape. This effectively reduces the length of the handle, thereby reducing the volume of the manual directional valve and minimizing space occupation. When the directional valve needs to be used, the second handle is rotated back to its original position, the locking block is inserted into the locking groove, and the fixing pin is inserted into the fixing hole, thus fixing the length of the second handle and the first handle. The directional valve can then be operated, making the operation simple and convenient. Attached Figure Description

[0026] To avoid excessive and unnecessary details, well-known structures or functions will not be described in detail in the following embodiments.

[0027] like Figure 1-5 The diagram shown is a structural schematic of a manual directional valve handle structure according to a preferred embodiment of the present invention.

[0028] In this embodiment, a valve body 1 and a handle 2 are included. A connecting rod 3 is provided at the top of the valve body 1, and the connecting rod 3 connects to the valve stem inside the valve body 1. (The internal structure of the reversing valve body is existing technology and will not be described in detail.) The handle 2 includes a first handle 4 and a second handle 5 hinged to the first handle 4. A connecting hole 6 is provided on one end surface of the first handle 4, and the connecting rod 3 is inserted into the connecting hole 6. The connecting rod 3 and the connecting hole 6 cooperate to complete the connection between the handle 2 and the valve body 1. A slot 7 is provided on one side of the first handle 4, and a locking block 8 is provided on one side of the second handle 5 to cooperate with the slot 7. A fixing hole 9 is provided on the surface of the locking block 8. A through hole 10 is provided on the surface of the first handle 4 through the slot 7, and a fixing pin 11 is provided in the through hole 10. A magnet is provided on one side of the first handle 4. 12. A magnet 13 is provided on one side of the handle 2 5 in conjunction with magnet 12. The locking block 8 is inserted into the locking groove 7, and the fixing pin 11 is inserted into the fixing hole 9. During transportation or after the operation of the reversing valve is completed, the fixing pin 11 is pulled out from the fixing hole 9, and the handle 2 5 is rotated to the side of the handle 1 4, so that the handle 2 5 and the handle 1 4 are rotated and folded, changing the shape of the handle 2. This can effectively reduce the length of the handle 2, thereby effectively reducing the volume of the manual reversing valve and reducing the space occupied. When the reversing valve needs to be used, the handle 2 5 is rotated back to its original position, the locking block 8 is inserted into the locking groove 7, and the fixing pin 11 is inserted into the fixing hole 9, completing the fixation of the length direction between the handle 2 5 and the handle 1 4, and the reversing valve can be operated. The operation is simple and convenient.

[0029] In this embodiment, the handle 2 5 is covered with a rubber sleeve 14. The rubber sleeve 14 has an opening 15 on one side to cooperate with the magnet 2 13. The rubber sleeve 14 is used to protect the worker's hands and prevent injury. The opening 15 is used to allow the magnet 2 13 to be exposed through the rubber sleeve 14 and contact the magnet 1 12.

[0030] In this embodiment, a connecting groove 16 is provided on the same side of the first handle 4 and the second handle 5. A hinge 17 is provided in the connecting groove 16. The hinge 17 is fixed in the connecting groove 16 by screws, and the hinge structure between the second handle 5 and the first handle 4 is realized by the hinge 17.

[0031] In this embodiment, the hinge 17 is located on the same side as the first magnet 12 and the second magnet 13. This structure allows the second handle to rotate toward the side of the first handle with the first magnet 12, so that after the second handle 5 and the first handle 4 are folded, the first magnet 12 and the second magnet 13 can come into contact and attract each other, thereby completing the fixation between the first handle 4 and the second handle 5 after the second handle 2 is folded.

[0032] The manual directional valve handle structure of this utility model can be installed, connected or set in a common mechanical way, and can be implemented as long as it can achieve its beneficial effect.

[0033] All technologies not described in detail in this utility model are known technologies. Those skilled in the art can easily implement this utility model based on their understanding of this specification, and the contents shown in the accompanying drawings are part of this specification.

[0034] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
