[0027] Embodiment 1

[0028] like Figure 1 and Figure 2As shown, an assembled sleeve joint proposed in this embodiment includes two half sleeves 1 that are symmetrically distributed and hot-melt connected to form a complete sleeve structure.

[0029] The outer side of the half sleeve 1 has reinforcing ribs 13, which effectively improves the overall structural strength. The inner wall of the half sleeve 1 is coaxially provided with a rubber ring 3, which is stuck in the trough of the corrugated pipe and can effectively seal the corrugated pipe and the sleeve joint.

[0030] The half sleeve 1 is a transparent structure. After being connected to the bellows, the transparent structure can facilitate visual observation of the internal situation to see if there is any leakage.

[0031] like Figure 2 As shown, the half sleeve 1 is a semicircular sleeve structure, and both ends are flared, which is convenient for inserting the corrugated pipe. The two half sleeves 1 of the semicircular sleeve structure are hot-melt connected, and the obtained complete sleeve structure has complete circular flared ends at both ends.

[0032] Two rows of positioning platforms 12 are symmetrically arranged along the axial direction on the inner side of the half sleeve 1. After the two half sleeves 1 are hot-melt connected into a complete sleeve structure, the two rows of positioning platforms 12 are used to position the corrugated pipes inserted from both sides.

[0033] The half sleeve 1 has an opening 101 and an anti-slipping piece is arranged at the opening 101. The anti-slipping piece is a buckle portion 11 bent toward the inside of the half sleeve 1. The buckle portion 11 is integrally formed with the half sleeve 1 or connected with the half sleeve 1 by hot melt adhesive.

[0034] ① If the buckle portion 11 is integrally formed with the half sleeve 1, when installing the bellows, the bellows is inserted from one end of the complete sleeve structure and the buckle portion 11 is pushed open. The buckle portion 11 is deformed and the bellows continues to move until the end of the bellows abuts against the positioning platform 12. At this time, the buckle portion 11 rebounds and is stuck in the trough of the bellows, achieving effective anti-slip limit.

[0035] ② If the buckle part 11 is connected to the half sleeve 1 by hot melt, the corrugated tube is first inserted into the inner side of the complete sleeve structure before hot melt connection, and then the buckle part 11 is connected to the half sleeve 1 by hot melt, and the buckle part 11 is stuck in the trough of the corrugated tube to prevent it from falling off.

[0036] The trough where the rubber ring 3 is clamped is located between the trough where the buckle portion 11 is clamped and the end of the bellows, thereby ensuring a sealing effect.

[0037] In this embodiment, the size of the half sleeve 1 is smaller than that of the complete sleeve structure, the size of the mold for producing the half sleeve 1 is small, and the production cost is low. The two semicircular half sleeves 1 can be closed and butted together and the two half sleeves 1 can be hot-melt connected at the butt joint by hot-melt equipment to obtain a complete sleeve structure.

[0038] Embodiment 2

[0039] The present embodiment provides an assembled sleeve joint. Compared with the first embodiment, in the present embodiment, Figure 3 As shown, the half sleeve 1 is a circular half sleeve structure, and a plurality of positioning platforms 12 distributed around the central axis are arranged inside the half sleeve 1. The length of the half sleeve 1 is half of the complete sleeve structure, and the ends of the two half sleeves 1 are butted, and the ends of the half sleeves 1 are hot-melted and connected using a hot-melt device to obtain a complete sleeve structure. During production, only the half sleeve 1 needs to be produced. The size of the half sleeve 1 is smaller than the complete sleeve structure, and the size of the mold used for producing the half sleeve 1 is small, and the production cost is low.

[0040] Embodiment 3

[0041] like Figure 4 and Figure 5 As shown, the present embodiment proposes an assembled sleeve joint. Compared with the first and second embodiments, in the present embodiment, the half sleeve 1 is a semicircular sleeve structure, and the anti-dropping member is a claw 2 plugged into the opening 101. The claw 2 is a U-shaped elastic structure and is clamped at the opening 101. Each claw 2 corresponds to two openings 101 and can be clamped at the two openings 101. When inserting the corrugated tube, the corrugated tube is directly inserted into the position abutting the positioning platform 12, and then the claw 2 is pinched and inserted into the opening 101. The claw 2 is clamped into the trough of the corrugated tube, and the rebound force of the claw 2 can ensure that it is firmly clamped at the opening 101.

[0042] In addition, instead of using the elastically inserted buckle claw 2, the buckle claw 2 can be directly inserted into the opening 101, and then the buckle claw 2 and the half sleeve 1 are connected by hot melt adhesive.

[0043] In this embodiment, the size of the half sleeve 1 is smaller than that of the complete sleeve structure, the size of the mold for producing the half sleeve 1 is small, and the production cost is low.

[0044] Embodiment 4

[0045] The assembled sleeve joint proposed in this embodiment is compared with the third embodiment. Figure 6 As shown, the half sleeve 1 is a circular half sleeve structure, the length of which is half of the complete sleeve structure, the two half sleeves 1 are butted at the ends and connected by hot melt equipment. The size of the half sleeve 1 is smaller than that of the complete sleeve structure, the mold size for producing the half sleeve 1 is small, and the production cost is low.

[0046] Embodiment 5

[0047] like Figure 7 and Figure 8As shown, the present embodiment proposes an assembled sleeve joint. Compared with the first to fourth embodiments, in the present embodiment, the half sleeve 1 is a semicircular sleeve structure, and the anti-slip part is a hot melt structure. After the bellows is inserted into the inner side of the complete sleeve structure and the end is abutted against the positioning platform 12, a hot melt gun is used to melt the hot melt strip on the bellows from the opening 101 until it extends out of the opening 101. After the material cools, the solidified hot melt structure can limit the half sleeve 1 to prevent the bellows from being detached from the present sleeve joint. The size of the half sleeve 1 is smaller than that of the complete sleeve structure, and the mold size for producing the half sleeve 1 is small, and the production cost is low.

[0048] Embodiment 6

[0049] The assembled sleeve joint proposed in this embodiment is compared with the fifth embodiment. Fig. 9 As shown, the half sleeve 1 is a circular half sleeve structure, the length of which is half of the complete sleeve structure, the two half sleeves 1 are butted at the ends and connected by hot melt equipment. The size of the half sleeve 1 is smaller than that of the complete sleeve structure, the mold size for producing the half sleeve 1 is small, and the production cost is low.

[0050] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
