Description

Technical Field

[0001] The utility model relates to the technical field of inner core tubes, in particular to an inner core tube structure of a gearbox which is easy to disassemble and replace. Background Art

[0002] Transmission core pipes generally refer to the pipes or channels within the transmission. These pipes may carry lubricating oil, coolant, or other working fluids to ensure proper functioning and heat dissipation of the transmission's internal components. For example, in some transmission designs, core pipes may be used to transport lubricating oil from the oil pan to the various gears and bearings to prevent excessive wear and overheating.

[0003] Because the inner core tube of the gearbox transports liquid for a long time, there will be residue on the inner wall of the inner core tube. After the residual liquid dries up, it will accumulate on the inner wall of the pipe. After repeated accumulation, the inner core tube will be blocked. At this time, the inner core tube needs to be disassembled and replaced. Utility Model Content

[0032] The disassembly and assembly mechanism 4 includes a fixing ring 402, which is fixedly connected to the surface of the external pipe 1. The fixing ring 402 is fixedly connected to the surface of the fixing ring 402 on all sides. The left and right surfaces of the inner core pipe 2 are fixedly connected to the connecting ring 41. The connecting ring 41 is provided with slots 401 on all sides. The inserting plate 42 is provided with a square groove 403. The inserting plate 42 is provided with a rectangular groove 49 on the side away from the external pipe 1. The connecting ring 41 is provided with an annular chute 45 on the side away from the external pipe 1. The annular slide 44 is slidably connected to the inside of the annular chute 45. The side of the annular slide 44 close to the inserting plate 42 is fixedly connected to the fixing plate 43. The other side of the fixing plate 43 is fixedly connected to the trapezoidal block 46. The rectangular groove 49 is plugged with a mounting plate 48. The mounting plate 48 is fixedly connected to the trapezoidal seat 47 on the side away from the inner core pipe 2.

[0033] There are eight slots 401 and eight plug-in boards 42 in number, and four are in a group. The left and right sides of the slot 401 are set to openings, the surface of the plug-in board 42 is plugged into the inside of the slot 401, both sides of the square slot 403 are set to openings, and the left and right sides of the rectangular slot 49 are set to openings. The square slot 403 and the rectangular slot 49 are connected, and the trapezoidal block 46 and the trapezoidal seat 47 are both plugged into the inside of the square slot 403. The trapezoidal block 46 and the trapezoidal seat 47 are symmetrically arranged, and the surfaces of the mounting plate 48 and the trapezoidal seat 47 are both plugged into the inside of the rectangular slot 49. The outer diameter of the mounting plate 48 is smaller than the opening size of the rectangular slot 49.

[0034] Furthermore, the fixed plate 43 is moved to drive the annular slide 44 to slide in the annular slide groove 45 until the fixed plate 43 drives the trapezoidal block 46 to move out of the square groove 403. At this time, the inner core tube 2 can be pulled to take the inserting plate 42 out of the slot 401, and the inner core tube 2 can be replaced. The operation is simple, saving time and effort.

[0035] Example 2

[0036] See Figure 1-8 On the basis of the first embodiment, the fixing mechanism 3 is further obtained to include a connecting plate 31, the connecting plate 31 is fixedly connected to the center of the side of the mounting plate 48 away from the external pipe 1, the connecting plate 31 is fixedly connected to the side away from the inner core tube 2 with a connecting seat 32, the outer side of the connecting seat 32 is fixedly connected to a connecting block 33, the connecting block 33 and the inside of the plug plate 42 are both threadedly connected with bolts 34, the surface of the connecting plate 31 is plugged into the inside of the rectangular groove 49, and the connecting seat 32 is arranged on the side of the plug plate 42 close to the inner core tube 2.

[0037] Furthermore, the bolt 34 is threadedly removed and the connecting seat 32 is pulled, so that the connecting seat 32 drives the connecting plate 31 to move, and the connecting plate 31 drives the mounting plate 48. The mounting plate 48 drives the trapezoidal seat 47 to move out of the square groove 403, so that the trapezoidal block 46 loses the restriction of the trapezoidal seat 47.

[0038] The inner core tube 2 improves the durability and fatigue resistance of the gearbox inner core tube by selecting high-quality materials and optimizing the structural design, ensuring that it maintains stable performance during long-term use.

[0039] When the device is in use, the inner core tube 2 needs to be disassembled and replaced. At this time, the bolt 34 is first threadedly removed and the connecting seat 32 is pulled so that the connecting seat 32 drives the connecting plate 31 to move, and the connecting plate 31 drives the mounting plate 48. The mounting plate 48 drives the trapezoidal seat 47 to move out of the square groove 403. At the same time, the trapezoidal block 46 loses the restriction of the trapezoidal seat 47, making it convenient to directly move the fixing plate 43 to drive the annular slide plate 44 to slide in the annular slide groove 45 until the fixing plate 43 drives the trapezoidal block 46 to move out of the square groove 403. At this time, the inner core tube 2 can be pulled to take the inserting plate 42 out of the slot 401, and the inner core tube 2 can be replaced. The operation is simple, saving time and effort.
