Detailed Embodiments

[0018] The following further elaborates the device of the present utility model in conjunction with specific embodiments. These embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the device of the present utility model, those skilled in the art can make various changes or modifications to the present utility model, and these equivalent forms also fall within the scope defined by the appended claims of the application.

[0019] Embodiment 1: Refer to Figure 1 is a structural view of the present utility model. A multifunctional plug structure includes an element plug structure 1 and a hose plug structure 3. A bent section 2 is connected to the lower end of the element plug structure 1. An internal thread structure 5 is formed in the inner side of the end of the element plug structure 1. When it is necessary to cut off the oil circuit, operate the present utility model to thread-connect the element plug structure 1 with the interface of the hydraulic element for plugging.

[0020] The bent section 2 is used to deal with hoses or component interfaces with bending angle requirements.

[0021] An external thread structure 6 is provided at the lower end of the hose plug structure 3. When it is necessary to cut off the oil circuit, the utility model is operated to thread-connect the hose plug structure 3 with the interface of the hose for plugging.

[0022] A first plug 10 is provided at the lower end of the bent section 2. A second slot is opened inside the first plug 10. An installation groove 11 is opened inside the second slot. An elastic pad 9 is provided inside the installation groove 11. A through first jack 7 is opened on the circumferential surface of the first plug 10. A first slot 13 is provided at the upper end of the hose plug structure 3. A second plug 12 is provided inside the first slot 13. A through second jack 8 is opened on the side wall of the first slot 13. A positioning pin 4 is inserted through the inside of the first jack 7 and the second jack 8. The first jack 7 and the second jack 8 have the same diameter. When the positioning pin 4 is inserted into the inside of the first jack 7 and the second jack 8 at the same time, the elastic pad 9 is in a state of being squeezed and deformed by the second plug 12. The second plug 12 is inserted and arranged inside the second slot. The first plug 10 is inserted and arranged inside the first slot 13. A round head structure is provided at the tail of the positioning pin 4 and a card slot is provided at the head. When the component plug structure 1 and the hose plug structure 3 are combined, the second plug 12 is inserted into the inside of the second slot and squeezes the elastic pad 9. The elastic pad 9 is squeezed and deformed by the force, and the second plug 12 can continue to penetrate deeper into the second slot along the axis until the outer wall of the end of the first slot 13 contacts the step at the tail of the first plug 10, and it is inserted to the deepest position and cannot move any more. At this time, the first jack 7 and the second jack 8 are aligned, and the positioning pin 4 can be inserted through. After inserting the positioning pin 4, release the external force applied to the hose plug structure 3 and the component plug structure 1. Because of the force generated by the elastic pad 9 to restore deformation, the second plug 12 will be pushed outwards. And because the positioning pin 4 restricts the movement of the first slot 13, the movement of the second plug 12 is restricted. At the same time, the first slot 13 will have a tendency of axial movement due to the force and squeeze the positioning pin 4 to prevent it from falling.

[0023] When the second plug 12 just contacts the elastic pad 9 and the elastic pad 9 is not squeezed and deformed, the first jack 7 and the second jacking hole are not coaxial, and the positioning pin 4 cannot be inserted. Only by squeezing the elastic pad 9 can the condition that the first jack 7 and the second jack 8 are coaxial be satisfied.

[0024] Embodiment 2: In order to further enhance the sealing effect of the plugging, the component plug structure and the hose plug structure 3 can be designed to be elastic structures. A cylindrical hollow groove is provided on the inner side of the end of the component plug structure 1, and a stepped groove is provided on the inner side of the end of the hose plug structure 3. When the internal thread structure 5 or the external thread structure 6 is connected to the component interface and the hose interface for sealing, the sealing performance can be further enhanced by the elastic structure. At the same time, the cylindrical hollow groove and the stepped groove can disperse the pressure to the side wall when subjected to liquid pressure, thereby assisting in sealing.

[0025] The utility model adopts a structural design in which a component plug and a hose plug are in the same body, and the component interface and the hose interface are blocked at the same time. The hose that cuts off the oil circuit can be fixed on the hose plug structure 3 and will not move at will, so that a single plug can block the two oil ports of the oil circuit at the same time, and the fixed blocked hose can reduce the operation intensity and improve the efficiency. The utility model adopts a combinable and disassembled structure, which can cope with different blocking operation requirements at any time, and realizes the function that the split structure can switch between single and double blocking use states.
