[0030] The following will be combined with the drawings in the embodiments of the utility model to 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 the embodiments. Based on the embodiments in 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.

[0031] Reference Figure 1 - Figure 3The utility model provides an embodiment: a connection sealing structure for a mixing pump, including a pump body 1. The pump body 1 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The pump body 1 is a mixing pump. The pump body 1 can be installed on a pipeline through a flange and can pump water in the pipeline. The front surface of the pump body 1 is provided with a mounting assembly. The mounting assembly can enhance the sealing between the flange 22 and the flange 1 21. The mounting assembly is provided with two groups, one group is installed at the water outlet of the pump body 1, and the other group is installed at the water inlet of the pump body 1. The component includes a flange 22, and a mounting groove 201 is provided on the front surface of the flange 22. The inner ring of the inner wall of the mounting groove 201 is fixedly connected to a rubber pad 26. A rubber ring 23 is inserted into the inner wall of the mounting groove 201. The rubber ring 23 is located on the outer ring of the rubber pad 26. When the rubber ring 23 and the rubber pad 26 are in contact, they can maintain a seal. The front surface of the rubber ring 23 is fixedly connected to a flange 21. An anti-loosening component is arranged inside the flange 21. The anti-loosening component can prevent the bolt 31 from reversing and loosening due to the vibration generated by the pump body 1, thereby ensuring the stability of the device. The amplitude of the reversal of the bolt 31 caused by a single vibration is limited.

[0032] Reference Figure 1 , Figure 2 , Figure 4 The installation assembly also includes a positioning block 24, a clamping plate 25 is fixedly connected to the lower surface of the positioning block 24, the positioning block 24 and the clamping plate 25 will move synchronously, the inner wall of the flange 21 is elastically connected to a slider 27 through a compression spring 28, and the slider 27 moves longitudinally.

[0033] Reference Figure 1 , Figure 4 , Figure 5 The anti-loosening assembly includes a bolt 31, a nut 32 is threadedly connected to the rear end of the outer wall of the bolt 31, the nut 32 is fixed to the bolt 31, a limiting groove 301 is provided on the rear surface of the bolt 31, and a positioning ring 33 is elastically connected to the inner wall of the flange 21 through a limiting spring 35, and a limiting block 34 is fixedly connected to the front surface of the positioning ring 33. There are multiple groups of limiting grooves 301 and limiting blocks 34, which are evenly distributed on the rear surface of the bolt 31.

[0034] Reference Figure 1 , Figure 4 , Figure 5The bolt 31 passes through and is threadedly connected to the front surface of the flange 1 21. The bolt 31 passes through and is threadedly connected to the front surface of the flange 22, so that the flange 1 21 and the flange 2 22 can be installed together. The limiting groove 301 is set in an arc shape. The positioning ring 33 is slidably connected to the inner wall of the flange 1 21 and slides horizontally. One end of the limiting spring 35 is fixedly connected to the inner wall of the rear side of the flange 1 21, and the other end of the limiting spring 35 is fixedly connected to the rear surface of the positioning ring 33. When the positioning ring 33 moves backward, it will squeeze the limiting spring 35 to generate a reaction force. The limiting block 34 is inserted into the inner wall of the limiting groove 301, which can limit the bolt 31 and prevent the bolt 31 from reversing. The front surface of the limiting block 34 is set in an arc shape. The arc surface of the limiting block 34 is squeezed, and the limiting block 34 will move backward.

[0035] Reference Figure 1 - Figure 3 The rear surface of the flange 22 is welded to the front surface of the pump body 1.

[0036] Reference Figure 1 , Figure 2 , Figure 4 The upper surface of the positioning block 24 is set as an inclined surface, and the lower surface of the clamping plate 25 is set as an arc surface. The lower surface of the clamping plate 25 contacts the outer ring of the rubber ring 23. The top of the front surface of the positioning block 24 is aligned with the top of the mounting groove 201. When the rubber ring 23 is inserted into the mounting groove 201, the inclined surface of the positioning block 24 will be squeezed by the flange 21, and the positioning block 24 will move toward the center of the flange 21, and will drive the clamping plate 25 to move synchronously, so that the rubber ring 23 and the rubber pad 26 fit together to form a seal.

[0037] Reference Figure 1 , Figure 2 , Figure 4 One end of the compression spring 28 is fixedly connected to the lower surface of the slider 27, and the other end of the compression spring 28 is fixedly connected to the inner wall of the bottom end of the flange 21. When the slider 27 moves downward, it will squeeze the compression spring 28 to generate a reaction force. The slider 27 penetrates and is slidably connected to the rear surface of the flange 21. The rear surface of the slider 27 is fixedly connected to the front surface of the positioning block 24. When the positioning block 24 moves, it will drive the slider 27 to move synchronously.

[0038] Reference Figure 1 , Figure 2 , Figure 4 There are multiple groups of positioning blocks 24, clamping plates 25, sliders 27, and compression springs 28. The multiple groups of positioning blocks 24, clamping plates 25, sliders 27, and compression springs 28 are arranged in a circular array with the center of the flange 21 as the origin. The multiple groups of clamping plates 25 can clamp the rubber ring 23 from multiple directions.

[0039] Working principle: When installing the device, first align flange 1 21 with flange 2 22 and move flange 1 21 backward. The backward moving flange 1 21 will drive the positioning block 24, the clamping plate 25 and the rubber ring 23 to move backward. The backward moving positioning block 24, the clamping plate 25 and the rubber ring 23 will be plugged into the installation groove 201, and the inclined surface of the positioning block 24 will be squeezed by flange 22 during the plugging process, so that multiple groups of positioning blocks 24 and clamping plates 25 will synchronously move toward the center of flange 22 to squeeze the rubber ring 23 so that the inner wall of the rubber ring 23 and the outer wall of the rubber pad 26 are tightly attached to maintain the seal, and when the positioning block 24 moves, it will drive the slider 27 to synchronously move to squeeze the compression spring 28 to generate a reaction force.

[0040] Then screw the bolt 31 onto the flange 1 21 and the flange 2 22 , and screw the nut 32 onto the bolt 31 . When the bolt 31 is tightened, the installation of the flange 1 21 and the flange 2 22 is completed, and the limiting block 34 is plugged into the limiting groove 301 .

[0041] When the pump body 1 is pumping water, it will vibrate, and the vibration will drive the bolt 31 to reverse. The reversed bolt 31 will squeeze the arc surface of the limit block 34. The arc surface of the limit block 34 will move backward after being squeezed. The limit block 34 moving backward will drive the positioning ring 33 to move backward to squeeze the limit spring 35 to generate a reaction force. The reaction force of the limit spring 35 will push the positioning ring 33 and the limit block 34 to move forward. The limit block 34 moving forward will squeeze the limit groove 301 to drive the bolt 31 to rotate forward and tighten, thereby ensuring the stability of the device.

[0042] When the device needs to be disassembled, first close the pump body 1, unscrew the bolts 31 and the nuts 32, and then separate the flange 1 21 and the flange 2 22. After separation, the positioning block 24 will not be squeezed, and the reaction force of the compression spring 28 will push the multiple groups of positioning blocks 24, the slider 27, and the clamping plate 25 to restore, and the clamping plate 25 will release the squeezing of the rubber ring 23.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
