Description

Technical Field

[0001] The utility model specifically relates to a fork slider based on an actuator. Background Art

[0002] An actuator uses liquid, gas, electricity or other energy sources and converts them into a driving action through a motor, a cylinder or other devices. The basic actuator is used to drive a valve to the fully open or fully closed position. The actuator used for a control valve can accurately move the valve to any position.

[0003] A fork slider is needed inside the actuator to drive the action switch of the actuator. However, after the currently used fork slider is used for a period of time, its interior is no longer lubricated and has no abrasion resistance, resulting in a short service life. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a fork slider based on an actuator to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A fork slider based on an actuator, including a slider body. An installation hole sleeving a moving rod inside the actuator is centrally opened in the slider body. Through holes are opened on both sides of the slider body. Graphite is connected in the through holes through a pop-up mechanism.

[0006] Wherein, as the pop-up mechanism pushes the graphite, the graphite moves from the through hole towards the installation hole and abuts against the moving rod to achieve lubrication.

[0007] Preferably, the pop-up mechanism includes a cover arranged on the outer side of the through hole. A threaded column is arranged at one end of the cover facing the inside of the through hole. Internal threads adapted to the external threads of the threaded column are opened on the inner wall of the through hole.

[0008] Preferably, a spring is connected to one end of the threaded column away from the cover, and the other end of the spring is connected to a push plate.

[0009] Preferably, moving blocks are arranged on both sides of the push plate, and a groove for placing graphite is inwardly opened on one side of the push plate away from the spring.

[0010] Preferably, chutes are opened in the slider body on both sides of the through hole. The chutes are communicated with the through hole. One end of the moving block away from the push plate extends into the chutes.

[0011] Preferably, the through hole is communicated with the installation hole.

[0012] Preferably, a plurality of through holes are opened and are respectively located on both sides of the slider body.

[0013] Technical effects and advantages of the present utility model: For the fork slider based on the actuator, the pre-prepared graphite is inserted into the push plate through the groove, and the graphite is pushed into the through hole. After rotating the cover, as the threaded column rotates, the external thread of the threaded column is adapted to the internal thread of the through hole, so that the graphite can completely enter the through hole and abut against the moving rod in the mounting hole, playing a lubricating role for the moving rod, reducing friction, and prolonging the service life of the fork slider. And as the graphite is continuously worn, the spring deforms and exerts a reaction force on the graphite, and the moving block slides along the length direction of the chute, which can drive the graphite to move towards the moving rod, so that the graphite can always maintain the lubrication function. The overall structure is simple and the practicability is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0020] In order to prolong the service life of the fork slider, refer to Figure 1 、 Figure 2 and Figure 3As shown in the figure, it includes a slider body 1. A mounting hole 2 for sleeving a moving rod inside an actuator is provided in the center of the slider body 1. Through holes 3 are provided on both sides of the slider body 1. A graphite 4 is connected in the through hole 3 through a pop-up mechanism. Among them, as the pop-up mechanism pushes the graphite 4, the graphite 4 moves from the through hole 3 towards the mounting hole 2 and abuts against the moving rod to achieve lubrication. The pre-prepared graphite 4 is inserted into the push plate 8 through a groove 10 and the graphite 4 is pushed into the through hole 3. After rotating the cover 5, as the threaded column 6 rotates, the external thread of the threaded column 6 is adapted to the internal thread inside the through hole 3, so that the graphite 4 can completely enter the through hole 3 and abut against the moving rod inside the mounting hole 2, playing a lubricating role for the moving rod, reducing friction, and prolonging the service life of the fork slider. And as the graphite 4 is continuously consumed, the spring 7 deforms and reacts on the graphite 4, and the moving block 9 slides along the length direction of the chute 11, which can drive the graphite 4 to move towards the moving rod, so that the graphite 4 can always maintain the lubrication function.

[0021] In order to make the graphite 4 contact with the moving rod to achieve lubrication, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in the figure, the pop-up mechanism includes a cover 5 provided outside the through hole 3. One end of the cover 5 facing the inside of the through hole 3 is provided with a threaded column 6. Internal threads adapted to the external threads of the threaded column 6 are provided on the inner wall of the through hole 3. As the threaded column 6 cooperates with the internal threads, after rotating the cover 5, the threaded column 6 can be inserted into the through hole 3 and the graphite 4 can be installed in the through hole 3. One end of the threaded column 6 away from the cover 5 is connected with a spring 7, and the other end of the spring 7 is connected with a push plate 8. When the graphite 4 continuously abuts against the moving rod, as time goes by, the graphite 4 will be consumed, resulting in the shortening of the length of the graphite 4. At this time, the spring 7 loses the extrusion of the graphite 4, and the elastic force will react on the push plate 8, causing the push plate 8 to push the graphite 4 so that the graphite 4 moves towards the moving rod and the two come into contact. Moving blocks 9 are provided on both sides of the push plate 8, and a groove 10 for placing the graphite 4 is inwardly opened on the side of the push plate 8 away from the spring 7. The graphite 4 can be placed through the groove 10 so that the graphite 4 can be pushed to move along with the movement of the push plate 8. Inside the slider body 1 and on both sides of the through hole 3, chutes 11 are provided. The chutes 11 are communicated with the through hole 3. One end of the moving block 9 away from the push plate 8 extends into the chute 11. When the spring 7 reacts on the push plate 8, the moving block 9 can move in the chute 11, making the movement of the push plate 8 smoother. The through hole 3 is communicated with the mounting hole 2 to facilitate the extension of the graphite 4 into the mounting hole 2 and abut against the moving rod. The through holes 3 are provided in several numbers and are respectively located on both sides of the slider body 1. A graphite 4 is provided in each through hole 3 to enhance the lubricity, reduce friction, and prolong the overall service life.

[0022] In use, first insert the pre-prepared graphite 4 onto the push plate 8 through the groove 10, and push the graphite 4 into the through hole 3. After rotating the cover 5, as the threaded column 6 rotates, the external thread of the threaded column 6 is adapted to the internal thread of the through hole 3, so that the graphite 4 can completely enter the through hole 3 and abut against the moving rod in the mounting hole 2, playing a lubricating role for the moving rod, reducing friction, and extending the service life of the fork slider. Moreover, as the graphite 4 is continuously worn, the spring 7 deforms and reacts on the graphite 4, and the moving block 9 slides along the length direction of the sliding groove 11, which can drive the graphite 4 to move towards the moving rod, so that the graphite 4 always remains in contact with the moving rod.

[0023] Finally, it should be noted that the above description is only the preferred embodiment of the present invention and is not used to limit the present invention.
