[0023] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0024] As Figure 1 shown, the valve core control assembly according to the embodiment of the present invention includes a bracket 1, a handle 2, and an adjusting rod 3.

[0025] Specifically, the handle 2 is rotatably connected to the bracket 1, and one end of the handle 2 is movably connected to the valve core connecting pin 5. The rotation of the handle 2 can drive the valve core connecting pin 5 to move.

[0026] It should be noted that the valve core connecting pin 5 is used to connect the valve core of the valve body. That is, the valve core control component of the present application can realize the opening or disconnection of the valve body by manipulating the movement of the valve core, thereby controlling the on-off of the hydraulic oil circuit in the mechanical equipment. Thus, the mechanical equipment can generate corresponding actions.

[0027] It can be understood that the handle 2 can be rotatably connected to the bracket 1 through a retaining pin. Swinging the upper end of the handle 2 (such as Figure 1 the up and down direction shown) can drive the valve core connecting pin 5 at the lower end of the handle 2 to move, thereby pushing and pulling the valve core. This valve core control method can quickly and conveniently realize the commutation of the valve body.

[0028] In addition, in some working conditions, more precise control of the valve body opening degree is required. The handle control of the valve core movement is slightly insufficient in terms of control accuracy. The present application adds a threaded rod adjustment structure to the valve core control component for precise regulation of the valve core. Specifically, as Figure 1 shown, the adjusting rod 3 is threadedly connected to the bracket 1 and can be screwed into and out of the bracket 1. A connecting component 4 is provided between the adjusting rod 3 and the valve core connecting pin 5. The connecting component 4 has a locked position and a released position. In the locked position, the adjusting rod 3 is connected to the valve core connecting pin 5. In the released position, the adjusting rod 3 is separated from the valve core connecting pin 5.

[0029] In other words, the adjusting rod 3 and the valve core 5 can be connected and disconnected. When precise regulation of the valve body opening degree is required, the connecting component 4 can be in the locked position to connect the adjusting rod 3 to the valve core connecting pin 5, and then the adjusting rod 3 is screwed to drive the valve core connecting pin 5 to move. When rapid commutation control of the valve core is required, the connecting component 4 can be in the released position, that is, disconnect the adjusting rod 3 and the valve core connecting pin 5, and use the rotation of the handle 2 to drive the valve core to move quickly, and the adjusting rod 3 will not interfere with the rapid regulation of the handle 2.

[0030] In addition, the adjusting rod 3 of the present application and the bracket 1 adopt a threaded fit, which is convenient for assembly, has high regulation accuracy, simple operation, and can control the opening degree of the valve body by controlling the number of threads of the adjusting rod 3 screwed into or out of the bracket 1, thereby adjusting the flow or pressure of the hydraulic system in the mechanical equipment and realizing fine adjustment of the operating actions of the mechanical equipment to meet the requirements of higher-precision working scenarios.

[0031] Furthermore, in actual working conditions, there is a phenomenon that the handle 2 needs to be continuously held by hand to maintain the opening degree of the valve body. To solve this problem, the present application can use the adjusting rod 3 to limit the position of the valve core connecting pin 5, thereby replacing the manual holding to reduce the working intensity of personnel, and this method has higher stability compared to manual holding. Specifically, when the handle 2 drives the valve core connecting pin 5 to a preset position, the adjusting rod 3 can be screwed to the preset position and connected to the valve core connecting pin 5 using the connecting component 4. At this time, the adjusting rod 3 can restrict the movement of the valve core connecting pin 5, and there is no need to continuously hold the handle 2 by hand.

[0032] It should be noted that when the adjusting rod 3 participates in precise regulation, the connecting component 4 is in the locked position. At this time, the adjusting rod 3 and the valve core connecting pin 5 cannot be easily separated to prevent the adjusting rod 3 from detaching during operation, which may cause a malfunction. When the handle 2 participates in rapid regulation, the connecting component 4 is in the released position. At this time, the operator needs to screw the adjusting rod 3 back to the initial position to avoid the adjusting rod 3 hindering the rapid operation of the handle 2. Thus, the connecting component 4 can be switched between the locked position and the released position, realizing the detachable connection between the adjusting rod 3 and the valve core connecting pin 5, so that the present application can be arbitrarily switched between two operation modes of controlling the movement of the valve core by the handle 2 and the adjusting rod 3, meeting the requirements of more working scenarios.

[0033] According to the valve core control component of the embodiment of the present invention, the handle is rotatably connected to the bracket, and one end of the handle is movably connected to the valve core connecting pin. The rotation of the handle can drive the valve core connecting pin to move. The adjusting rod is threadedly connected to the bracket and can be screwed into and out of the bracket relative to the bracket. A connecting component is provided between the adjusting rod and the valve core connecting pin. The connecting component has a locked position and a released position. In the locked position, the adjusting rod is connected to the valve core connecting pin. In the released position, the adjusting rod is separated from the valve core connecting pin. That is, the present application can control the movement of the valve core in two ways. It can drive the movement of the valve core by swinging the handle to achieve rapid redirection of the valve body, and can also precisely control the opening degree of the valve body by the number of turns of screwing the adjusting rod in or out, realizing fine adjustment of the operating actions of mechanical equipment to meet the requirements of higher-precision working scenarios. At the same time, the threaded connection method between the adjusting rod and the bracket has a locking function, which can control the valve core positioning, so that the mechanical equipment can maintain the same working state for a long time, avoiding the operator continuously holding the handle. In addition, the connecting component can be switched between the locked position and the released position, realizing the detachable connection between the adjusting rod and the valve core connecting pin, so that the present application can be arbitrarily switched between two operation modes of controlling the movement of the valve core by the handle and the adjusting rod, meeting the requirements of more working scenarios.

[0034] Furthermore, as Figure 1As shown, one end of the valve core connecting pin 5 facing the adjusting rod 3 is provided with a mating hole 51. One end of the adjusting rod 3 facing the valve core connecting pin 5 can extend into and disengage from the mating hole 51. The connecting assembly 4 includes a limiting protrusion 41 and a limiting groove 42. One of the inner wall of the mating hole 51 and the outer wall of the adjusting rod 3 is provided with the limiting protrusion 41, and the other is provided with the limiting groove 42. The limiting protrusion 41 is movable between a locked position and a released position along the radial direction of the valve core connecting pin 5. In the locked position, the limiting protrusion 41 is at least partially engaged in the limiting groove 42. In the released position, the limiting protrusion 41 disengages from the limiting groove 42.

[0035] It can be understood that the valve core connecting pin 5 and the adjusting rod 3 achieve an insertion and mating relationship through the mating hole 51. That is, when the adjusting rod 3 is connected to the valve core connecting pin 5, the end of the adjusting rod 3 can be inserted into the mating hole 51. After the mating is in place, the limiting protrusion 41 extends into the limiting groove 42. Then, further screwing the adjusting rod 3 can drive the valve core connecting pin 5 to move synchronously, thereby achieving precise control of the valve body opening. When the adjusting rod 3 is separated from the valve core connecting pin 5, the limiting protrusion 41 disengages from the limiting groove 42, and screwing the adjusting rod 3 can disengage from the mating hole 51. Then, the adjusting rod 3 is no longer connected to the valve core connecting pin 5. At this time, the handle 2 can control the valve core connecting pin 5 to quickly reverse.

[0036] Preferably, the mating hole 51 is provided at the central position of the valve core connecting pin 5, thereby ensuring that when the adjusting rod 3 pushes the valve core connecting pin 5, all parts of the valve core connecting pin 5 are evenly stressed, avoiding wear and improving the durability of the valve core connecting pin 5.

[0037] It can be understood that the mating form of the limiting protrusion 41 and the limiting groove 42 is simple and the anti-disconnection reliability is high. In addition, the limiting protrusion 41 can move along the radial direction of the valve core connecting pin 5, that is, the up and down direction, which facilitates the switching of the working states of the connecting assembly 4 between the locked position and the released position, realizes the quick connection and disconnection between the adjusting rod 3 and the valve core connecting pin 5, and thus the valve core control assembly can be arbitrarily switched between the control modes of the handle 2 and the adjusting rod 3.

[0038] It should be noted that the limiting groove 42 is arranged circumferentially along the outer wall of the adjusting rod 3 or the inner wall of the mating hole 51. Thus, when the adjusting rod 3 and the valve core connecting pin 5 are connected to each other, the limiting protrusion 41 can rotate circumferentially in the limiting groove 42, avoiding affecting the screwing-in or screwing-out process of the adjusting rod 3.

[0039] Preferably, as Figure 1As shown in the figure, the limit projection 41 is connected to the inner wall of the mating hole 51 through an elastic member 43, and the elastic member 43 has a force to drive the limit projection 41 to move from the release position to the locking position. Thus, after the adjusting rod 3 is assembled in place, the elastic member 43 can automatically push the limit projection 41 into the limit groove 42. When it is necessary to disconnect the cooperation between the adjusting rod 3 and the valve core connecting pin 5, the elastic member 43 can be compressed by screwing out the adjusting rod 3 and squeezing the inner wall, so that the limit projection 41 disengages from the limit groove 42, and the disassembly and assembly are simple and efficient.

[0040] Further, as Figure 1 shown, a first groove 52 extending radially along the inner wall of the mating hole 51 is provided, the elastic member 43 is arranged in the first groove 52. In the locking position, the limit projection 42 extends out of the first groove 52, and in the release position, the limit projection 42 is located in the first groove 52, that is, the first groove 52 provides a moving space for the up-and-down movement of the limit projection 41.

[0041] Further, as Figure 1 shown, the limit projection 41 is spherical.

[0042] It can be understood that the spherical limit projection 41 is convenient to extend into or out of the limit groove 42, and the surface of the spherical limit projection 41 is smooth, which can reduce the friction force when the limit projection 41 moves in the groove or the limit groove 42, facilitating the up-and-down movement of the limit projection 41 in the groove or the circumferential sliding in the limit groove 42 quickly, and increasing the smoothness of the operation of the valve core control assembly.

[0043] Further, as Figure 1 shown, a limit plate 31 is further provided on the outer peripheral surface of the adjusting rod 3. In the locking position, the limit plate 31 can abut against one end of the valve core connecting pin 5 facing the adjusting rod 3.

[0044] It can be understood that the limit plate 31 of the adjusting rod 3 is arranged at one end facing the valve core connecting pin 5. Thus, when the adjusting rod 3 is connected to the valve core connecting pin 5, the limit plate 31 can be in positioning cooperation with the valve core connection 5 to accurately position the insertion depth of the adjusting rod 3. In addition, the limit plate 31 can prevent the adjusting rod 3 from being screwed out of the bracket 1, preventing dust, water vapor, etc. from entering the bracket 1 and being corroded.

[0045] Further, as Figure 1 shown, the bracket 1 has a cavity, the handle 2 is sleeved on the outer wall of the cavity and one end of the handle 2 extends into the cavity and is connected to the valve core connecting pin 5. One side of the cavity has a through hole, and the valve core connecting pin 5 can pass through the through hole and be connected to the valve core.

[0046] Specifically, the upper wall of the bracket 1 has a through-hole through which the handle 2 can be inserted and swing reciprocally, and the lower end of the handle 2 is connected to the valve core connecting pin 5. The front wall of the bracket 1 has a through-hole through which the valve core connecting pin 5 can be inserted and move reciprocally, and the front end of the valve core connecting pin 5 is connected to the valve core. Thus, the reciprocal swing of the handle 2 can drive the front and back movement of the valve core connecting pin 5, thereby realizing the rapid change of the position of the valve core.

[0047] It can be understood that the cavity of the bracket 1 provides space for the activities of the handle 2 and the valve core connecting pin 5. And to ensure the cleanliness of the inner cavity of the bracket 1 and avoid corrosion, rubber products and the like need to be added to the through-holes through which the handle 2 and the valve core connecting pin 5 are inserted for anti-pollution sealing treatment. For example, a rubber dust cap is added at the insertion part of the handle 2, and a rubber pad is added at the through-hole through which the valve core connecting pin 5 is inserted.

[0048] Furthermore, as Figure 1 shown, the adjusting rod 3 is inserted through the side wall opposite to the through-hole in the cavity along the moving direction of the valve core connecting pin 5, that is, the rear wall of the bracket 1 has a threaded through-hole through which the adjusting rod 3 can be screwed in or out, and this through-hole is concentric with the through-hole of the valve core connecting pin 5 on the front wall of the bracket 1. Thus, it can be ensured that the adjusting rod 3 and the valve core connecting pin 5 are axially opposite. When the adjusting rod 3 is connected to the valve core connecting pin 5, the adjusting rod 3 can control the position change of the valve core connecting pin 5.

[0049] Furthermore, as Figure 1 shown, the inner wall surface opposite to the through-hole in the cavity has a second groove 11. In the release position, the adjusting rod 3 can be screwed out until the end of the adjusting rod 3 facing the valve core connecting pin 5 is located in the second groove 11, that is, the second groove 11 can hide the matching structure of the adjusting rod 3 facing the valve core connecting pin 5 in the rear wall of the bracket 1 when the adjusting rod 3 is not required to control the valve core. Thus, the setting of the adjusting rod 3 will not affect the maximum stroke of the axial movement of the valve core and avoid affecting the operating space of the handle 2.
