[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0022] like Figure 1As shown, a grease rotary joint that is easy to operate includes a joint body 1 and a reinforcement component 3. The left end of the joint body 1 is connected to a fixed joint 2, the right end of the joint body 1 is provided with a flange 4, and the interior of the flange 4 is provided with a movable joint 5. A cooling box 6 is provided on the outside of the middle part of the joint body 1. The hollow cooling box 6 is filled with coolant, which can play a role in preliminary cooling of the grease passing through the interior of the rotary joint, thereby preventing the grease from overheating and affecting the service life of the rotary joint. The cooling box 6 is shaped like a hollow rectangular body, and an inlet and outlet pipe 7 is provided on the top of the cooling box 6.

[0023] like Figure 2 As shown, a reinforcing assembly 3 for increasing the stability of the joint and facilitating operation is arranged on the outside of the fixed joint 2, and the reinforcing assembly 3 includes a fixing plate 301, a card end plate 302, a fastening plate 303, a spring 304 and a fastening bolt 305. The card end plate 302 is installed on the inner side of the end of the fixing plate 301. The fixing plate 301 and the card end plate 302 are symmetrically arranged in two groups about the fixed joint 2, and the shape of the fixing plate 301 is arc-shaped. The fixing plate 301 and the card end plate 302 are aligned with the connection position after the fixed joint 2 is connected. The arrangement acts as an outer cover to prevent the connection position of the fixed joint 2 from loosening and to protect against external force collision, and a fastening plate 303 is installed on the side of the fixing plate 301, and a spring 304 is arranged on the inner side of the fastening plate 303. The fastening plate 303 and the spring 304 are distributed vertically, and there are four springs 304. The spring 304 is used to pull the fixing plates 301 on both sides together through its own resilience, which is convenient for the fixation of the fastening bolts 305, and a fastening bolt 305 is arranged in the middle of the fastening plate 303.

[0024] like Figure 3 As shown, the lower end of the cooling box 6 is provided with an auxiliary component 8 for assisting cooling, and the auxiliary component 8 includes a cooling tube 801 and a circulation tube 802, and the end of the cooling tube 801 is connected to the circulation tube 802, the cooling tube 801 and the circulation tube 802 are internally communicated, the cooling tube 801 is installed in the cooling box 6, and the cooling tube 801 and the circulation tube 802 are an integrated structure, the cooling tube 801 can flow ice water in the cooling box 6 through the circulation tube 802, the cooling effect on the high-temperature grease is increased, and the cooling effect of the cooling box 6 is avoided.

[0025] In summary, the easy-to-operate grease rotary joint is first based on Figure 1-Figure 3In the structure shown in the figure, the fixed joint 2 and the movable joint 5 of the joint body 1 are connected to the grease container and the conveying end respectively. After the fixed joint 2 is installed, the fixing plate 301 and the card end plate 302 are wrapped on the outside of the fixed joint 2, so that the card end plate 302 is limited on the bolt of the joint position, and the loosening of the connection position of the fixed joint 2 and the protection of external force collision are prevented. During installation, the spring 304 is used to pull the fixing plates 301 on both sides together through its own resilience, and then the fastening bolts 305 are passed through the fastening plates 303 to fix the fixing plates 301. When the grease is conveyed, the cooling box 6 is filled with coolant through the inlet and outlet pipes 7, which plays a preliminary cooling role for the grease passing through the inside of the rotary joint, avoiding the overheating of the grease and affecting the service life of the rotary joint. When conveying high-temperature grease, ice water can flow in the cooling box 6 through the cooling pipe 801 and the circulation pipe 802, thereby increasing the cooling effect of the high-temperature grease and increasing the cooling effect of the cooling box 6.
