[0023] Embodiment 1

[0024] like Figure 1-Figure 3 As shown, the transparent visible detachable snap-on sleeve joint proposed in this embodiment includes a connecting tube, the inner circumference of the connecting tube has two coaxial positioning parts 12 that are symmetrically distributed along the axial direction, and the inner side of the connecting tube is coaxially provided with a filter part located between the two positioning parts 12. The positioning part 12 is a circular ring structure or a fan-shaped structure, and the installation position of the corrugated tube 100 is positioned by the positioning part 12.

[0025] A rubber ring 3 is coaxially mounted on the inner circumference of the connecting tube. Two rubber rings 3 are symmetrically distributed along the axial direction of the connecting tube. The two positioning portions 12 are located between the two rubber rings 3. The rubber ring 3 is clamped in the trough of the corrugated tube 100 to achieve sealing.

[0026] Two groups of socket assemblies are symmetrically distributed along the axial direction on the connecting tube, and each group of socket assemblies includes a number of socket groups distributed around the central axis of the connecting tube, and each socket group includes two sockets 101. U-shaped buckles 4 are plugged into the two sockets 101. The buckles 4 are elastic, and there are limit parts on the outer peripheral surfaces of both sides of the U-shaped buckles 4. After the bellows 100 is installed in place, the two ends of the buckle 4 are pressed, and the buckle 4 is deformed inward, and the buckle 4 is inserted into the inner side of the two sockets 101. The buckle 4 extends into the trough of the bellows 100 for limiting. The buckle 4 is released, and the elastic force of the buckle 4 itself can ensure that it is firmly stuck in the socket 101. At the same time, the limit part set can effectively prevent the buckle 4 from being directly pulled outward to separate from the socket 101. The overall connection structure will not loosen, can withstand the influence of earthquakes and internal and external pressures, has anti-bending and anti-vibration capabilities, and will not leak.

[0027] A plurality of reinforcing ribs 102 are alternately arranged on the inner circumference and the outer circumference of the connecting tube, which effectively improves the structural strength and anti-bending ability of the entire sleeve joint.

[0028] The connecting tube is a transparent structure, that is, the connecting tube is made of transparent material, which is convenient for observing the situation when connecting the corrugated pipe.

[0029] The connecting tube is a sleeve 1 with a straight cylindrical shape and open ends, and the sleeve 1 is a complete circular tube.

[0030] The inner circumference of the sleeve 1 has a coaxially distributed mounting ring portion 11, and the mounting ring portion 11 has a coaxially distributed flow channel. The mounting ring portion 11 is located between two positioning portions 12. The filter portion is a filter plate a2 mounted on the mounting ring portion 11. The diameter of the filter plate a2 is smaller than the inner diameter of the positioning portion 12. The filter plate a2 moves from one axial end of the sleeve 1 to the inner side of the sleeve 1, passes through the positioning portion 12, and is connected to the mounting ring portion 11. The connection method between the filter plate a2 and the mounting ring portion 11 adopts but is not limited to bolt fixing or clamping, and a sealing layer is provided on the end surface where the filter plate a2 is connected to the mounting ring portion 11.

[0031] Furthermore, a support seat 5 may be provided at the bottom of the sleeve 1, and the bottom surface of the support seat 5 is a plane, so that the entire sleeve joint can be stably placed through the support seat 5. The length of the support seat 5 may be shorter than the axial length of the sleeve 1 to expose the area where the insertion hole 101 is provided, so that more buckles 4 can be inserted conveniently, thereby improving the stability of the sleeve joint when connected to the corrugated pipe 100.

[0032] This embodiment can position the two bellows 100 so that there is a gap between the two bellows 100, and there will be no loss of sealing when encountering thermal expansion and contraction, and the filtering effect can be achieved through the filter. When connecting the bellows 100, the two bellows 100 are inserted from both ends of the sleeve 1, and the two bellows 100 are respectively abutted against the positioning parts 12 on both sides, and the ends of the two bellows 100 do not contact each other. The rubber ring 3 is clamped in the trough of the bellows 100 and connected to the inner wall of the sleeve 1 to ensure the sealing of the bellows connection. The buckle 4 can be clamped into the jack 101 and the trough of the bellows 100. After the bellows 100 is installed in place, it is firmly limited to prevent loosening. There will be no water leakage when using this sleeve joint to connect the two bellows 100. The filter plate a2 can filter impurities, and the transparent sleeve 1 is convenient for observing the internal situation and cleaning the impurities at the filter plate a2 in time.

The two sleeves 1 can be connected to form a complete connecting tube structure. The complete connecting tube structure is open at both ends for inserting two bellows 100. Sealing strips are installed between the upper and lower ends of the two sleeves 1 to prevent water leakage. A groove for the sealing strip to be inserted can be provided on the sleeve 1. The filter part is a filter plate b6. When installing the filter plate b6, the filter plate b6 is placed between the two sleeves 1, and then the two sleeves 1 are connected, and the filter plate b6 is connected to the sleeve 1.

[0036] The sleeve 1 has a support platform 13 at the bottom and a connecting plate 14 at the top. The bottom surface of the support platform 13 is a plane, which is convenient for stably placing the sleeve joint. The support platform 13 has a U-shaped groove with an opening facing downward. The support platform 13 is provided with a through hole a connected to the U-shaped groove, and the connecting plate 14 is provided with a through hole b. The two support platforms 13 are connected at the through hole a by bolts and nuts. The U-shaped groove facilitates the connection operation. The two connecting plate 14 are connected at the through hole b by bolts and nuts, thereby realizing the detachable connection of the two sleeves 1.
