DETAILED DESCRIPTION

[0026] The following will be combined with the attached embodiment of the utility model Figure 1-4, clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0027] A reducer that can quickly complete refueling, includes a reducer body 1, a flange part 2 is detachably installed on one side of the top of the reducer body 1, a shaft rod 3 is fixedly installed on one side of the top of the reducer body 1, a movable arm 4 is rotatably installed on the surface of the shaft rod 3, a bolt sleeve 5 is penetrated through one side of the top of the movable arm 4, a sealing bolt 16 is installed on the internal thread of the bolt sleeve 5, four sliding holes 9 evenly distributed and located on the outside of the bolt sleeve 5 are opened on one side of the top of the movable arm 4, a sliding rod 7 is slidably installed inside the sliding hole 9, the bottom ends of the four sliding rods 7 are fixedly connected with a retaining ring 6 compatible with the flange part 2, the surface of the sliding rod 7 is sleeved with a spring 8, the two ends of the spring 8 are respectively fixedly connected to the retaining ring 6 and the movable arm 4, and a positioning component is movably provided on the top of the shaft rod 3.

[0028] The specific usage process is as follows: when filling the reducer with oil, the user first pulls the top plate 14 upwards, and the top plate 14 will also pull the latch 15 upwards, and then the latch 15 will move out of the slot 10, releasing the restriction on the movable arm 4, and at the same time, the top plate 14 will also drive the limit slider 12 to move upward in the limit slide slot 11. The shape of the limit slider 12 and the limit slide slot 11 are both hexagonal, so they can play a limiting role when the limit slider 12 slides, thereby ensuring the stability of the limit slider 12, the top plate 14 and the latch 15 when they are active, and the size of the top plate 14 is larger than the size of the shaft rod 3, and there will be a protruding part on the edge, which can play an anti-slip role when the user moves the top plate 14, thereby providing a good working environment for the user. The invention provides convenience, wherein the spring 2 13 is stretched upward by the limit slider 12 when the user is in use, and the spring 2 13 will retract and pull the limit slider 12, the top plate 14 and the bayonet 15 back to their original position when the user releases the limit slider 12, so that the bayonet 15 will be stuck in the slot 10 again to prepare for the next use, and then the user can rotate the movable arm 4, and the movable arm 4 will also drive the bolt sleeve 5 and the clamping ring 6, the slide rod 7 and the spring 1 8 arranged on the movable arm 4 to move when it is rotated and moved away. It should be noted that when moving the movable arm 4, the user must first loosen the sealing bolt 16, and when the sealing bolt 16 is loosened, it will also move upward out of the inner cavity of the reducer body 1 and the flange 2, and the bolt sleeve 5 can also be sealed. The sealing bolt 16 plays a guiding and limiting role. It should be noted that the sealing bolt 16 is not removed from the bolt sleeve 5 after being loosened. It is only necessary to move the end of the sealing bolt 16 out of the flange 2. When the user moves the movable arm 4, the clamping ring 6 originally on the inner side of the flange 2 is squeezed by the flange 2 and is forced to move upward. At the same time, the clamping ring 6 will also push the slide bar 7 upward, and the slide bar 7 will slide in the corresponding slide hole 9. At the same time, the clamping ring 6 will also compress the spring 1 8 when moving. When the clamping ring 6 moves out of the inner side of the flange 2, the clamping ring 6 will rebound to its original position under the action of the spring 1 8. At this time, the oil filling hole on the flange 2 will leak, and then the user can align the oil filling hole for oil filling, or put a funnel on it for oiling, so as to To provide convenience for refueling, after the refueling work is completed, the user turns the movable arm 4 back. At this time, the clamping ring 6 is squeezed upward again by the flange 2 until the clamping ring 6 is aligned with the oil filling hole on the flange 2. The clamping ring 6 will be pushed back and inserted into the oil filling hole on the flange 2 under the action of the spring 1 8. At the same time, the sealing bolt 16 is also aligned with the oil filling hole. Then the user tightens the sealing bolt 16 and installs the sealing bolt 16 into the oil filling hole on the flange 2. In this way, the refueling work of the reducer can be completed quickly, with less time and high efficiency. Among them, after the movable arm 4 is reset, the pin 15 will be inserted into the slot 10 again to position the movable arm 4 and complete the refueling work, which provides convenience for the user's work.

[0029] Therefore, a structural design is adopted on the reducer to provide guidance for the installation of the sealing bolt. After the user finishes refueling, the sealing bolt can be quickly and accurately aligned in the refueling hole on the reducer body 1 under the guidance of the structure. Then the user can quickly tighten and fix the sealing bolt, thereby quickly completing the refueling work, saving refueling time, improving refueling efficiency, and providing convenience for the user's work.

The mounting bolts 17 are used to fasten the flange 2 to the reducer body 1.

[0039] Specifically, the setting of spring 2 13 is that when the user is in use, spring 2 13 will be stretched upward by the limit slider 12. When the user releases the limit slider 12, spring 2 13 will retract and pull the limit slider 12, the top plate 14 and the latch 15 back to their original position, so that the latch 15 will be inserted into the slot 10 again to prepare for the next use.

[0040] A transmission shaft 19 is fixedly mounted on the output end of the reducer body 1 , and an adaption groove 20 is formed on the top of the transmission shaft 19 .

[0041] Specifically, the transmission shaft 19 and the adapter groove 20 are arranged such that the transmission shaft 19 is installed inside the reducer body 1 and is used for outputting power to the reducer body 1, while the adapter groove 20 is used for facilitating docking and installation with the transmission components, and also plays a role in ensuring the stability of the reducer body 1 and the docking equipment after docking and installation, providing convenience for the user's work.
