DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-Figure 6 A hydraulic component connector for engineering machinery includes a main body tube 1, a connecting ring 2 is provided at the top and the bottom of the main body tube 1, two connecting components 3 are provided on the outer surface of the main body tube 1, and the connecting component 3 includes a connecting block 301, and the connecting block 301 is fixed to the outer surface of the main body tube 1 by bolts, and the two sides of the connecting block 301 are rotatably connected with rotating plates 302, and the inner surfaces of the two rotating plates 302 are respectively welded with two clamping blocks 303, and two connecting screws 304 are inserted between the two rotating plates 302, and one end of the connecting screw 304 is The threaded sleeve is provided with a connecting nut 305, and two grooves 4 are provided on the outer surface of the main body tube 1, and the corresponding block 303 is rotatably engaged in the groove 4. Through the design of the connecting component 3, the block 303 in the connecting component 3 is engaged with the connecting ring 2 and the groove 4, so as to connect and fix the main body tube 1 with the hydraulic element and the connecting pipe respectively. Not only is the connection and fixing effect good, but it is also not easy to loosen. The connection by the connecting screw 304 and the connecting nut 305 is convenient for the operator to operate, and it is convenient for the operator to disassemble, replace or maintain the connecting head.

[0025] Among them, the rotating plate 302 and the clamping block 303 are both arc-shaped structures. The rotating plate 302 and the clamping block 303 with arc-shaped structures can be matched with the clamping groove 4, the connecting ring 2 and the main tube 1 when installed and used, so as to improve the connection and fixing effect of the installation and use of the connector. The outer surfaces of the two connecting rings 2 are respectively threaded with multiple fastening screws 5 inserted therein. The use of the fastening screws 5 can reinforce the connecting rings 2 when they are respectively connected to the hydraulic components and the connecting pipes. The inner surface of the main tube 1 is clamped with a sealing cylinder 6, and the inner surface of the sealing cylinder 6 is integrally formed with a sealing ring 7. The design of the sealing cylinder 6 can seal the hydraulic components and the connecting pipes connected in the main tube 1, and the sealing ring 7 can seal the connection between the hydraulic components and the connecting pipes. Such a double sealing structure can avoid the leakage of the conveying medium between the hydraulic components and the connecting pipes, thereby ensuring the practicality of the connector.

[0026] The outer surface of the connecting screw 304 is threaded with an anti-loosening screw 8, and the anti-loosening screw 8 is in contact with the connecting nut 305. The design of the anti-loosening screw 8 can limit and fix the connection between the connecting screw 304 and the connecting nut 305 to avoid loosening of the connection, thereby ensuring the fixation of the connection between the connecting component 3 and the main tube 1 and the connecting ring 2.

[0027] Working principle of this embodiment: When in use, the operator first fixes the two connecting rings 2 on the outer surfaces of the hydraulic element and the connecting pipe, and tightens the fastening screws 5 in the connecting rings 2 until the fastening screws 5 are respectively connected to the corresponding hydraulic element and the connecting pipe. Then, the operator inserts one end of the hydraulic element and the connecting pipe from the two ends of the main tube 1, until one end of the hydraulic element and the connecting pipe contacts the top and bottom of the sealing ring 7 in the sealing tube 6, respectively. Then, the operator rotates the rotating plates 302 of the two connecting components 3 to close them, so that the two clamping blocks 303 on the rotating plates 302 are respectively located in the clamping groove 4 and the connecting ring 2. The top or bottom of the connector 3 is then connected by the connecting screw 304 and the connecting nut 305, and finally, the anti-loosening screw 8 is installed on the connecting screw 304. In this way, the connection, installation and use between the connector and the hydraulic element and the connecting pipe are completed; at this time, if the connector needs to be disassembled, replaced or maintained, the operator unscrews the anti-loosening screw 8, the connecting nut 305 and the connecting screw 304 in turn, and then rotates and opens the rotating plate 302, so that the main tube 1 can be pulled out from the hydraulic element and the connecting pipe for replacement or maintenance. In this way, the operator completes the use of the connector.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
