[0031] The side fixing assembly includes a fixing plate 6, a sliding rod 7, a fixing rod 8, a second spring 9, a positioning block 10 and an elastic rope 12; the fixing plate 6 is arranged at a position corresponding to the side of the fixing slot 2; the flange body 1 is provided with an oblique groove at a position corresponding to the fixing plate 6; the bottom of the fixing plate 6 is fixedly connected with a sliding rod 7; the sliding rod 7 is slidably connected to the inside of the fixing rod 8; a second spring 9 is fixedly connected between the sliding rod 7 and the fixing rod 8; a positioning block 10 is fixedly connected to the end of the fixing rod 8; the positioning block 10 is slidably connected to the inside of the positioning cavity 11; the positioning cavity 11 is provided inside the flange body 1; the positioning block 10 An elastic rope 12 is fixedly connected between the flange body 1 and the positioning cavity 11; during operation, when the bolt fixes the flange body 1 through the fixed through slot 2, the fixing plate 6 can be pressed down, so that the sliding rod 7 presses the sliding rod 7 to retract into the inside of the fixing rod 8. In the process of pressing down the fixing plate 6, the inclined surface of the fixing plate 6 and the side wall of the inclined slot cooperate with each other, so that the fixing plate 6 can move toward the inside of the fixed through slot 2, and then the side wall of the bolt can be fixed by the fixing plate 6, so that the bolt is more firmly and stably inside the fixed through slot 2. At the same time, through the mutual clamping of the positioning block 10 and the positioning cavity 11, the fixing plate 6 can be less tilted during the movement.

[0032] The interior of the positioning block 10 is slidably connected with a top block 13; a third spring 14 is fixedly connected between the top block 13 and the positioning block 10; an ejection groove is provided on the side wall of the flange body 1; the ejection groove is provided at the position corresponding to the top block 13; during operation, when the fixing plate 6 moves and thereby drives the positioning block 10 to move, the positioning block 10 can push the top block 13 out of the ejection groove, thereby fixing the bottom position of the bolt, thereby making the bolt more stable inside the fixing through groove 2.

[0033] A roller 15 is installed inside the fixed plate 6; the side wall of the roller 15 contacts the side wall of the inclined groove of the flange body 1; during operation, when the fixed plate 6 is pressed down, the roller 15 can convert the sliding friction between the fixed plate 6 and the inclined groove into rolling friction, thereby making the friction force between the fixed plate 6 and the inclined groove smaller, thereby reducing the wear between the fixed plate 6 and the inclined groove.

[0034] A fixing bolt 16 is installed at the bottom of the flange body 1; a sliding block 17 is slidably connected inside the fixing bolt 16; a connecting rod 18 is fixedly connected to the side wall of the sliding block 17; a contact block 19 is fixedly connected to the end of the connecting rod 18; a fourth spring 20 is fixedly connected between the sliding block 17 and the fixing bolt 16; during operation, when the flange body 1 is installed, when the bolt is installed, the fixing block 4 can be pushed into the inside of the first sliding cavity 3, and then the fixing block 4 can be fixed by the fixing bolt 16, so that when the flange body 1 is installed, the fixing block 4 will not affect the installation process of the flange body 1, when the fixing bolt 16 is screwed into the flange body 1, the contact block 19 first contacts the side wall of the fixing block 4, and then when the fixing bolt 16 is further screwed in, the sliding block 17 can squeeze the fourth spring 20, and at the same time, the elastic force of the fourth spring 20 can push the fixing bolt 16 and the thread of the flange body 1 to be more closely contacted, so that the fixing bolt 16 has a better fixing effect on the fixing block 4.

[0035] One end of the fourth spring 20 is fixed to the side wall of the rotating disk 21; the rotating disk 21 is rotatably connected to the inside of the fixing bolt 16; a ball 22 is arranged between the rotating disk 21 and the fixing bolt 16; during operation, when the fixing bolt 16 is screwed in, the sliding block 17 can drive the rotating disk 21 to rotate together through the fourth spring 20, thereby effectively preventing the fourth spring 20 from being affected by the rotation and causing the fourth spring 20 to be damaged.

[0036] An anti-skid pad 23 is fixedly connected to the side wall of the contact block 19; the size and shape of the anti-skid pad 23 are arranged corresponding to the contact block 19; during operation, when the contact block 19 contacts the side wall of the fixed block 4, the anti-skid pad 23 can increase the contact area between the contact block 19 and the fixed block 4, thereby increasing the friction between the contact block 19 and the fixed block 4, so that the contact block 19 has a stronger fixing ability to the fixed block 4.

[0037] A frosted soft block 24 is fixedly connected to the side wall of the fixing plate 6; the frosted soft block 24 is arranged on one side of the fixing plate 6 corresponding to the inside of the fixing groove 2; during operation, when the fixing plate 6 contacts the side wall of the bolt, the frosted soft block 24 can increase the contact area between the fixing plate 6 and the bolt, thereby making the frosted soft block 24 have a stronger fixing ability on the bolt.

[0038] Embodiment 2

[0039] See also Fig. 9As shown, compared with Example 1, as another implementation of the present invention, a plurality of contact grooves 25 are provided on the side wall of the fixing block 4; during operation, when the fixing block 4 fixes the bolt, the contact grooves 25 are squeezed and can fit on the side wall of the fixing block 4, thereby making the contact area between the fixing block 4 and the bolt larger, so that the fixing effect of the fixing block 4 on the bolt is better.

[0040] Working principle: during operation, when the water cooler needs to be connected and fixed, the flange body 1 can be placed at the connection, and then the fixing groove 2 can be fixed by bolts to fix the flange body 1 at the connection. By setting the fixing groove 2 and the side fixing assembly, the flange body 1 can be adapted to bolts and connecting pipes of more models and sizes, thereby effectively solving the problem of poor adaptability of the existing flange. At the same time, after the flange body 1 is fixed by bolts, the fixing block 4 is pushed by the first spring 5, and the side fixing assembly can make the bolts and the flange body 1 more firmly fixed.

[0041] When the bolt fixes the flange body 1 through the fixed through slot 2, the fixing plate 6 can be pressed down, so that the sliding rod 7 presses the sliding rod 7 to retract into the inside of the fixing rod 8. In the process of pressing down the fixing plate 6, the inclined surface of the fixing plate 6 cooperates with the side wall of the inclined slot, so that the fixing plate 6 can move toward the inside of the fixing through slot 2, and then the side wall of the bolt can be fixed by the fixing plate 6, so that the bolt is more firmly and stably inside the fixing through slot 2. At the same time, through the mutual engagement of the positioning block 10 and the positioning cavity 11, the fixing plate 6 can be less inclined during the movement.

[0042] When the fixing plate 6 moves, thereby driving the positioning block 10 to move, the positioning block 10 can push the ejection block 13 out of the ejection groove, thereby fixing the bottom position of the bolt, so that the bolt is more stable inside the fixing through groove 2.

[0043] When the fixing plate 6 is pressed down, the roller 15 can change the sliding friction between the fixing plate 6 and the inclined groove into rolling friction, thereby making the friction between the fixing plate 6 and the inclined groove smaller, thereby reducing the wear between the fixing plate 6 and the inclined groove.

[0044] When installing the flange body 1, when installing the bolts, the fixing block 4 can be pushed into the first sliding cavity 3, and then the fixing block 4 can be fixed by the fixing bolts 16, so that when the flange body 1 is installed, the fixing block 4 will not affect the installation process of the flange body 1. When the fixing bolts 16 are screwed into the flange body 1, the contact block 19 first contacts the side wall of the fixing block 4, and then when the fixing bolts 16 continue to be screwed in, the sliding block 17 can squeeze the fourth spring 20. At the same time, the elastic force of the fourth spring 20 can push the fixing bolts 16 and the threads of the flange body 1 to be in closer contact, so that the fixing bolts 16 have a better fixing effect on the fixing block 4.

[0045] When the fixing bolt 16 is screwed in, the sliding block 17 can drive the rotating disk 21 to rotate together through the fourth spring 20, thereby effectively preventing the fourth spring 20 from being affected by the rotation and causing damage to the fourth spring 20.

[0046] When the contact block 19 contacts the side wall of the fixing block 4 , the anti-skid pad 23 can increase the contact area between the contact block 19 and the fixing block 4 , thereby increasing the friction between the contact block 19 and the fixing block 4 , thereby making the contact block 19 more capable of fixing the fixing block 4 .

[0047] When the fixing plate 6 contacts the side wall of the bolt, the frosted soft block 24 can increase the contact area between the fixing plate 6 and the bolt, so that the frosted soft block 24 has a stronger fixing ability on the bolt.
