[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.
[0026] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.
[0027] The following describes, with reference to the accompanying drawings, some embodiments of a water pump sealing structure provided by this utility model. Example 1
[0028] Combination Figure 1-4 As shown, the present invention provides a water pump sealing structure, including a pumping mechanism 100 and a sealing mechanism 200. The pumping mechanism 100 includes a pump 110 and a water pipe 120 disposed on one side of the pump 110.
[0029] The sealing mechanism 200 includes a connector 210 screwed to the pump 110's pumping end, multiple slots 220 formed on the inner wall of the connector 210, an annular toothed disc 230 movably sleeved on the outside of the water pipe 120, multiple T-shaped plates 240 installed on one side of the annular toothed disc 230, multiple rollers 250 movably connected to the T-shaped plates 240, and a pressure plate 260 sleeved on the outside of the connector 210.
[0030] Furthermore, the multiple slots 220 are evenly spaced and arranged in a ring. The sum of the thicknesses of the annular toothed disc 230 and the T-shaped plate 240 is equal to the depth of the slot 220. This size design allows the annular toothed disc 230 to be fully pressed into the connector 210, thereby firmly pressing the water pipe 120.
[0031] Furthermore, the annular toothed disc 230 is composed of a ring and multiple protrusions, with the multiple protrusions spaced at equal intervals and surrounding the outer side of the ring. The diameter of the ring is equal to the inner diameter of the connector 210. The shape and size design of the annular toothed disc 230 ensures that the ring can press against the water pipe 120.
[0032] Furthermore, multiple protrusions are movably engaged with multiple slots 220 respectively. The two bending positions of the protrusions are both set as arc surfaces 300. Setting the outer end of the protrusion as an arc surface 300 can ensure that the protrusion presses the water pipe 120 without damaging it. Example 2
[0033] Combination Figure 3 As shown, based on Embodiment 1, the roller 250 is set in an I-shape and its diameter is equal to the width of the slot 220. With this shape design, the roller 250 can easily squeeze the water pipe 120 to deform, so that the pipe wall of the water pipe 120 can easily be inserted into the slot 220. Example 3
[0034] Combination Figure 2 As shown, in the above embodiment, the pump 110 is provided with a sealing ring 400 at the pumping end. The sealing ring 400 is interference-fitted into the inner end of the connector 210. The sealing ring 400 can improve the sealing between the connector 210 and the pump 110.
[0035] The working principle and usage process of this utility model are as follows: When this device is put into actual use, first connect the connector 210 to the water pump end of the pump 110, then pass the water pipe 120 through the annular toothed disc 230 and put it on the outside of the connector 210, then tighten the pressure plate 260 so that the pressure plate 260 presses the outer end of the water pipe 120, then align the protrusion with the slot 220, then press the annular toothed disc 230 into the connector 210, and then the water pipe 120 is pressed twice by the connector 210 and the annular toothed disc 230, thereby ensuring the sealing performance.
[0036] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
