[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution: an external oil kettle master cylinder that is convenient for loading and unloading. It includes an oil kettle assembly 1, and a master cylinder assembly 2 is arranged on the side of the oil kettle assembly 1. The master cylinder assembly 2 includes a master cylinder 21. One end of the master cylinder 21 is connected to a pedal. The oil pipe 210 arranged below the master cylinder 21 is connected to a booster. When the clutch is depressed, the oil is strongly pressed into the booster pump arranged inside the booster, so that the valve inside the booster is opened. When the clutch is completely released, the oil flows back into the interior of the external oil kettle 11. The amount of oil pumped out by the master cylinder 21 determines the distance of the push rod stroke inside the booster pump. A connecting piece 22 protrudes from the side of the master cylinder 21. A connecting ring 23 is fixedly connected inside the connecting piece 22. A clamping block 26 is fixedly connected to the surface of the connecting ring 23. The connecting ring 23 is used to fix the clamping block 26 inside the connecting piece 22. A clamping groove 260 is opened on the inner wall of the top of the clamping block 26. The clamping groove 260 is used to clamp the convex block 12 inside. When a screwing member 24 arranged at one end of the clamping block 26 is screwed into the interior of the connecting piece 22, the clamping block 26 is squeezed inward through the sliding groove 240 opened inside the screwing member 24, so that the external oil kettle 11 is fixed inside the connecting piece 22 through the convex block 12. The connecting piece 22 is internally rotatably connected with a screwing member 24. The inner wall of the screwing member 24 is recessed toward both sides with sliding grooves 240. One end of the sliding groove 240 can first fit the gradually decreasing part of one end of the clamping block 26 into the interior of the screwing member 24. When the sliding groove 240 gradually decreases, it forms a squeezing effect on the outer wall of the clamping block 26, reducing the gap between the clamping blocks 26, so that the clamping groove 260 opened at one end of the clamping block 26 plays a role of fixedly clamping the convex block 12 clamped inside.
[0023] Please refer to Figures 1-4, the oil pot assembly 1 includes an externally mounted oil pot 11. A convex block 12 protrudes from one side of the side surface of the externally mounted oil pot 11. A fuel pipe 210 extends outwardly downward from the master cylinder 210. The fuel pipe 210 is used to connect to an external booster. The inner wall of the connecting member 22 is provided with a threaded structure, and the surface of the screwing member 24 is provided with a threaded structure. The connecting member 22 and the screwing member 24 are threadedly connected. A sealing gasket is provided inside one end of the screwing member 24 that contacts the externally mounted oil pot 11 to prevent oil inside the externally mounted oil pot 11 from leaking out during use after the screwing member 24 is connected to the connecting member 22. There is a gap between the clamping blocks 26. When the gap is large, the convex block 12 can be allowed to be clamped into the inside of the clamping groove 260. When the gap decreases, the convex block 12 is clamped inside the clamping groove 260 for fixation. One end of the clamping block 26 where the clamping groove 260 is opened gradually decreases, facilitating the screwing member 24 to be sleeved outside the clamping block 26. The greater the length of the screwing member 24 screwed into the connecting member 22, the greater the width of the clamping block 26 sleeved inside the sliding groove 240, the greater the squeezing effect on the convex block 12 clamped inside the clamping groove 260, and the stronger the fixing effect. Handles 25 extend from both ends of the screwing member 24, and the screwing member 24 is sleeved outside the clamping block 26.
[0024] During use, first, the convex block 12 protruding from the extended part on the side of the externally mounted oil pot 11 is used to clamp the convex block 12 into the inside of the clamping groove 260 opened at one end of the clamping block 26. The screwing member 24 is rotated so that the screwing member 24 gradually rotates into the inside of the connecting member 22. After the sliding groove 240 opened on the inner wall of the screwing member 24 contacts one end of the clamping block 26, it exerts a squeezing force on one end of the clamping block 26. Since there is a gap between the clamping blocks 26, the clamping blocks 26 contract toward the middle after being squeezed, fixing the convex block 12 clamped inside the clamping groove 260, thereby fixing the externally mounted oil pot 11 on the side of the master cylinder 21. Since the handles 25 protruding from both ends of the screwing member 24 are rotated, there is no need to use screws for fixation. After the screwing member 24 is screwed into the inside of the connecting member 22, the externally mounted oil pot 11 can be connected to the master cylinder 21 through the connecting member 22. A sealing washer is provided at the connection between the connecting member 22 and the externally mounted oil pot 11, which can avoid leakage problems during the use of the device, and maintenance and replacement are very convenient.
[0025] In this embodiment, for the externally mounted oil pot master cylinder that is convenient for loading and unloading, among the above components, its own structural features and working principles all adopt existing technologies, which will not be elaborated here.
