Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] This utility model provides, for example Figure 1-5 A shielded pump with a leak-proof connection structure is shown, comprising:

[0038] The shielded pump connector 100 and pipe connector 200 are provided with threaded rings 210 on the outer side of both the shielded pump connector 100 and the pipe connector 200, which are adapted to the threaded portion 310. A receiving housing 300 is fitted onto the outer side of the shielded pump connector 100 and the pipe connector 200. Threaded portions 310 are provided on both sides of the inner surface of the receiving housing 300. The shielded pump connector 100 and the pipe connector 200 are fixed together by the engagement of the threaded rings 210 and the threaded portions 310. Both ends of the 00 are fixedly installed with directional grooves 320. These directional grooves 320, in conjunction with the positioning component 400, position the positioning component 400. Four limiting blocks 330 are provided on the outer side of the receiving shell 300, with every two limiting blocks 330 positioned on either side of the directional groove 320. A limiting groove 340 is formed on the side of the directional groove 320 closest to the center of the receiving shell 300. The limiting blocks 330 and the limiting groove 340 cooperate with the positioning component 400 to position the positioning component. To prevent the locking assembly 400 from being easily removed, a third rubber sealing gasket 350 is bonded to the inner surface of the directional groove 320, which contacts the two receiving joints 430. The locking assembly 400 is wrapped by the third rubber sealing gasket 350 to improve the sealing effect. The locking assembly 400 has two sets, which are respectively sleeved on the outside of the shielded pump joint 100 and the pipe joint 200 and cooperate with the receiving shell 300. The first rubber sealing gasket 500 is bonded to the inner surface of the receiving shell 300 and is set between the shielded pump joint 100 and the pipe joint 200. The setting of the first rubber sealing gasket 500 is squeezed under the push of the locking assembly 400 to achieve a sealing effect. At the same time, under the restriction of the locking assembly 400, the receiving shell 300 is connected and fixed to the shielded pump joint 100 and the pipe joint 200, so as to prevent the shielded pump joint 100 and the pipe joint 200 from loosening during use, affecting the seal, and causing leakage at the liquid reconnection.

[0039] In this embodiment, during installation, the shielded pump connector 100 and the pipe connector 200 are inserted into the inside of the receiving housing 300 and connected to the threaded portion 310 via the threaded ring 210 to fix the shielded pump connector 100 and the pipe connector 200. Then, the two locking components 400 are spliced ​​together and inserted into the inside of the directional groove 320, and then connected to the limiting block 330 to fix the two locking components 400 together.

[0040] In some embodiments of this utility model, the locking assembly 400 includes: an arc-shaped plate 410, which fastens to the outside of the shielded pump connector 100 or the pipe connector 200; a second rubber sealing gasket 420, which is bonded to the inner surface of the arc-shaped plate 410 and contacts the shielded pump connector 100 or the pipe connector 200, thereby clamping and fixing the shielded pump connector 100 and the pipe connector 200 through the cooperation of the arc-shaped plate 410 and the second rubber sealing gasket 420, preventing the shielded pump connector 100 and the pipe connector 200 from shaking during use; and two receiving joints 430, which are respectively fixed at both ends of the arc-shaped plate 410 and slide along the directional groove 320. The through-joint 430 connects the two arc-shaped plates 410 together and ensures the stability of the two arc-shaped plates 410 after they are connected. The through-hole 440 is opened on the through-joint 430. After the through-joint 430 slides to the designated position, the through-hole 440 corresponds to the limiting groove 340. The bolt 450 has both ends passing through the through-hole 440 and the limiting groove 340. There are two nuts 460, which are installed on both ends of the bolt 450 and contact the limiting block 330. The two arc-shaped plates 410 are connected together by the cooperation of the bolt 450 and the nuts 460, and the through-joint 430 is connected and fixed to the limiting block 330.

[0041] In this embodiment, during use, two arc-shaped plates 410 are spliced ​​together and fitted onto the outside of the shielded pump connector 100 or pipe connector 200. At the same time, the receiving joints 430 on the two arc-shaped plates 410 are spliced ​​together. Then, the arc-shaped plates 410 are pushed to slide and inserted into the interior of the directional groove 320. Then, the bolts 450 are passed through the mounting through hole 440 and the limiting groove 340, and the two nuts 460 are fixed at both ends of the bolts 450 and in contact with the limiting block 330.

[0042] The working method of this utility model:

[0043] During installation, insert the shielded pump connector 100 and the pipe connector 200 into the inside of the receiving housing 300, and connect them to the threaded part 310 through the threaded ring 210 to fix the shielded pump connector 100 and the pipe connector 200. Then, splice the two arc plates 410 and fit them on the outside of the shielded pump connector 100 or the pipe connector 200, while splicing the receiving parts 430 on the two arc plates 410 together. Then, push the arc plates 410 to slide and insert them into the inside of the directional groove 320. Then, pass the bolt 450 through the mounting through hole 440 and the limiting groove 340, and fix the two nuts 460 at both ends of the bolt 450 respectively, so that they contact the limiting block 330.

[0044] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
