[0003] Currently, some hydraulic rotary joints lack a filter component during use. When the input oil is used for a long time, sediment will accumulate, and the lack of an anti-clogging device will affect the stability of the high-pressure hydraulic rotary joint. Utility Model Content

[0004] The purpose of this invention is to provide a high-pressure hydraulic rotary joint that can solve the problem of instability in the operation of the high-pressure hydraulic rotary joint caused by sediment buildup and the lack of an anti-clogging device when using input oil for a long time.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-pressure hydraulic rotary joint, comprising a joint body, a top cover, and a conical plug;

[0006] The top cover is equipped with a ring-shaped filter screen;

[0007] The top cover is equipped with a movable spring, and the movable spring is equipped with a conical plug.

[0008] Preferably, a liquid inlet threaded tube is rotatably mounted on the bottom of the adapter body, and a rotating nut is fixedly mounted on the outer wall of the liquid inlet threaded tube, and the liquid inlet threaded tube communicates with the interior of the adapter body.

[0009] Preferably, a sealing groove is provided on the top of the adapter body, and a sealing ring is fixedly installed on the bottom of the top cover, with the sealing ring located in the sealing groove on the adapter body.

[0010] Preferably, a side plate is fixedly installed on the outer wall of the top cover, a movable block is fixedly installed on the bottom of the side plate, and a threaded connection hole is provided on one side of the adapter body.

[0011] Preferably, a limiting block is fixedly installed on the outer wall of the adapter body. An opening is provided inside the limiting block for a movable block to move. The movable block is located inside the opening on the limiting block. A movable groove is provided inside the limiting block. A limiting spring is fixedly installed on one inner wall of the movable groove. A connecting movable plate is fixedly installed on one side of the limiting spring. A limiting round rod is fixedly installed on one side of the connecting movable plate. A sliding rod is fixedly installed on the other side of the connecting movable plate. One end of the sliding rod extends to one side of the limiting block, and the sliding rod and the limiting block are slidably installed.

[0012] Preferably, the movable block has a groove inside for the movement of the limiting rod, and the limiting rod is located inside the groove.

[0013] Preferably, a movable spring is fixedly installed at the bottom of the top cover, a conical plug is fixedly installed at the bottom of the movable spring, and a telescopic rod is fixedly installed at the bottom of the top cover, with the free end of the telescopic rod fixedly installed to the top of the conical plug.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This high-pressure hydraulic rotary joint, through the setting of the annular filter screen, can filter the oil during the oil transportation process. This avoids the situation where sediment will accumulate during long-term use of input oil, and the lack of an anti-clogging device will affect the stability of the high-pressure hydraulic rotary joint's operation. This ensures the normal practicality of the hydraulic press. Furthermore, the setting of the limiting rod can limit the side plate and the limiting block, which facilitates the separation of the adapter body from the top cover. This makes it easier for subsequent users to clean the annular filter screen, remove impurities inside the adapter body, and ensure the effectiveness of the adapter body. Attached Figure Description

[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] Please see Figure 1-3 This utility model provides a technical solution: a high-pressure hydraulic rotary joint, including a joint body 1, a top cover 3 and a conical plug 5; the top cover 3 is provided with an annular filter screen 7; the top cover 3 is provided with a movable spring 4, and the movable spring 4 is provided with a conical plug 5.

[0022] Furthermore, an inlet threaded pipe 2 is rotatably mounted on the bottom of the adapter body 1, and a rotating nut is fixedly mounted on the outer wall of the inlet threaded pipe 2. The inlet threaded pipe 2 communicates with the interior of the adapter body 1. A sealing groove is opened on the top of the adapter body 1, and a sealing ring 15 is fixedly mounted on the bottom of the top cover 3. The sealing ring 15 is located in the sealing groove on the adapter body 1. A side plate 8 is fixedly mounted on the outer wall of the top cover 3, and a movable moving block 10 is fixedly mounted on the bottom of the side plate 8. A threaded connection hole is opened on one side of the adapter body 1, and a limit block 9 is fixedly mounted on the outer wall of the adapter body 1. An opening for the movable moving block 10 to move is opened inside the limit block 9, and the movable moving block 10 is located inside the opening on the limit block 9. A movable groove is opened inside the limit block 9, and a limit spring 11 is fixedly mounted on the inner wall of one side of the movable groove. A connecting movable plate 12 is fixedly mounted on one side of the limit spring 11, and a limit round rod 13 is fixedly mounted on one side of the connecting movable plate 12. A sliding rod 1 is fixedly mounted on the other side of the connecting movable plate 12. 4. One end of the sliding rod 14 extends to one side of the limiting block 9, and the sliding rod 14 and the limiting block 9 are slidably installed. The movable block 10 has a groove inside for the limiting rod 13 to move. The limiting rod 13 is located inside the groove. A movable spring 4 is fixedly installed at the bottom of the top cover 3. A conical plug 5 is fixedly installed at the bottom of the movable spring 4. A telescopic rod 6 is fixedly installed at the bottom of the top cover 3. The free end of the telescopic rod 6 is fixedly installed at the top of the conical plug 5. This setting can filter the oil, which can avoid the situation where sediment will form when the oil is input for a long time. Without an anti-clogging device, the stability of the high-pressure hydraulic rotary joint will be affected, thus ensuring the normal operation of the hydraulic press. Furthermore, the setting of the limiting rod 13 can limit the side plate 8 and the limiting block 9, which makes it easy to separate the adapter body 1 from the top cover 3. This makes it easier for the user to clean the annular filter screen 7 and remove impurities inside the adapter body 1, ensuring the effectiveness of the adapter body 1.

[0023] Working principle: During use, the oil is delivered to the interior of the adapter body 1 through the inlet threaded pipe 2, and then discharged through the threaded connection hole on the adapter body 1. The oil is filtered through the annular filter screen 7. When there are many impurities inside the adapter body 1, the sliding rod 14 is pulled. The sliding rod 14 moves and drives the connecting movable plate 12 and the limiting round rod 13 to move. After the limiting round rod 13 moves, the limitation on the movable block 10 can be released. Then, the adapter body 1 and the top cover 3 can be separated to clean the impurities inside the adapter body 1.
