[0026] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0027] like Figure 1-3 As shown, a high-efficiency water and electricity pipeline sealing connection device includes a first pipeline 1 and a second pipeline 4. The first pipeline 1 is provided with an inserting mechanism and a progressive clamp mechanism, and the second pipeline 4 is provided with a flipping and pushing mechanism for clamping and pushing the progressive clamp mechanism.

[0028] The insertion mechanism includes an inner shrinkage tube 3 welded to the first pipe 1, the inner shrinkage tube 3 is plugged into and matched with the second pipe 4, and a first fixing ring 2 is fixed on the outer circumference of the first pipe 1;

[0029] The progressive clamp mechanism includes two slot plates 9 and a tightening buckle 14. The two slot plates 9 are symmetrically arranged on the first fixing ring 2 through a hinge seat. The opposite sides of the two slot plates 9 are each provided with a plurality of inner slots 91, each of which is triangular in shape. The opposite sides of the two slot plates 9 are each provided with a plurality of outer slots 92.

[0030] The outer circumference of the second pipe 4 is fixed with a tapered ring 17 adapted to the inner groove 91 . The outer circumference of the second pipe 4 is fixed with a second fixing ring 5 . The second fixing ring 5 is symmetrically formed with grooves that match the groove plate 9 .

[0031] As an optional embodiment, three O-rings 10 and a sealing ring 12 are sleeved on the inner shrinkage tube 3, and three positioning rings 11 and a retaining ring 13 are fixed on the inner shrinkage tube 3. The three O-rings 10 are located on the left side of the three positioning rings 11, and the sealing ring 12 is fitted on the right side of the retaining ring 13. The sealing ring 12 is adapted to the left side of the second pipe 4. The outer diameters of the three O-rings 10 are successively increased from right to left. With such an arrangement, after the three O-rings 10 are inserted into the second pipe 4, the O-rings 10 form an extrusion seal between the inner shrinkage tube 3 and the second pipe 4, and then rely on the sealing ring 12 to form a secondary seal between the second pipe 4 and the retaining ring 13, thereby improving the connection sealing effect between the first pipe 1 and the second pipe 4.

[0032] Refer to the attached Figure 2 The right sides of the two slot plates 9 are respectively fixed with a fixed shaft 15 and a blocking shaft 16. One side of the tightening buckle 14 is movably sleeved on the fixed shaft 15. The tightening buckle 14 is set to a semicircular shape and the inner side surface of the other side is formed with a plurality of squeezing grooves 141 that are adapted to the blocking shaft 16. With such a setting, when the tightening buckle 14 is flipped over by relying on the fixed shaft 15, the squeezing grooves 141 on the tightening buckle 14 can slide over the blocking shaft 16 in an offset manner, thereby improving the ability to merge the two slot plates 9 one by one and improving the clamping effect of the inner slot 91 on the slot plate 9 and the clamping cone ring 17.

[0033] Refer to the attached Figure 3 The flipping and pushing mechanism includes two card push plates 8 and two movable shafts 18. A telescopic rod 21 is fixed between the upper sides of the two card push plates 8. The two card push plates 8 are adapted to the outer card slots 92. With this arrangement, the telescopic adjustment of the telescopic rod 21 can be used to adjust the two card push plates 8 to expand and contract, and it is also convenient to pull the card push plates 8 by hand to flip them.

[0034] Furthermore, a stabilizing block 6 is fixed to the lower side of the second fixing ring 5, and a sleeve plate 7 is fixed on the stabilizing block 6. The opposite sides of the two movable shafts 18 are sleeved in the sleeve holes on the sleeve plate 7. The two movable shafts 18 are respectively fixedly connected to the lower sides of the two push plates 8. Such an arrangement allows the withdrawing plate to rely on the sleeve connection between the movable shaft 18 and the sleeve plate 7, which facilitates the flipping and movable adjustment of the push plate 8.

[0035] Furthermore, the two movable shafts 18 are respectively provided with springs 19, and the two movable shafts 18 are respectively fixed with limiting rings 20. One side of the spring 19 is fixedly connected to the limiting ring 20, and the other side of the spring 19 is fixedly connected to the side of the sleeve plate 7. With such a configuration, the elasticity of the spring 19 can be relied upon. On the one hand, when the push plate 8 is flipped and expanded outward, there is elastic expansion space. On the other hand, the elastic contraction of the spring 19 can be utilized to pull the push plate 8 to always keep it close to each other and merge, so that the push plate 8 is stuck in the outer slot 92 to form a trip on the slot plate 9, and can drive the slot plate 9 to move.

[0036] With the above structure, the inserting mechanism on the first pipe 1 is plugged and positioned with the second pipe 4, so that the inner shrinkage tube 3 is plugged with the second pipe 4, and then the two slot plates 9 are clamped between the two push plates 8 on the flip and push mechanism. At the same time, the slot plate 9 is also clamped in the groove on the second fixing ring 5, and the inner slot 91 on the slot plate 9 is clamped with the cone ring 17. Then, the push plate 8 is driven to slide through multiple outer slots 92 by pushing the telescopic rod 21, and the push plate 8 is pulled to be clamped on the outer slot 92 by the spring 19. Then, the telescopic rod 21 can be pulled with The movable card push plate 8 is turned over by the movable shaft 18, thereby driving the card slot plate 9 to move synchronously, so that the inner card slot 91 on the card slot plate 9 can be offset and slide over the card cone ring 17, and by relying on the squeeze of the two card push plates 8, the card slot plate 9 can be stuck on the card cone ring 17 by relying on the inner card slot 91 when it stops moving, so that the inner shrinkage tube 3 and the three O-rings 10 can be squeezed and inserted into the second pipe 4 in sequence to form a seal. Then, as the card push plate 8 is cyclically turned and pushed, the sealing ring 12 on the inner shrinkage tube 3 is driven to contact the right side of the second pipe 4 to form a seal again;

[0037] Then the tightening buckle 14 is flipped over by relying on the fixed shaft 15, so that the squeezing groove 141 on the tightening buckle 14 is flipped and stuck on the blocking shaft 16, and then the tightening buckle 14 is squeezed and pressed close to the second pipe 4, so that the squeezing groove 141 on the tightening buckle 14 slides over the blocking shaft 16, and drives the two slot plates 9 to merge and tighten and stick to the second pipe 4, so that the slot plate 9 can be constrained, so that the inner slot 91 remains blocked by the cone ring 17.

[0038] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
