[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Refer to Figure 1 - Figure 3 As an embodiment provided by the present invention: A crimping type external thread stainless steel conversion tee includes a connecting pipe 1 for connecting a drainage pipe. An outer wall of the connecting pipe 1 is provided with a connecting component 2 for connecting a water inlet pipe. The connecting component 2 includes a sliding sleeve 21 for driving a threaded head 22 to move. The sliding sleeve 21 slides on the outer wall of the connecting pipe 1. The sliding sleeve 21 can slide left and right on the outer wall of the connecting pipe 1. A front end of the sliding sleeve 21 is fixedly connected with a threaded head 22 for directly connecting a water inlet pipe. An outer thread is provided on an outer wall of the threaded head 22, and the outer thread can be used to connect with a water inlet pipe. An inner wall of the connecting pipe 1 is fixedly connected with a support ring 4 for supporting a drainage pipe. By using the support ring 4 to block the drainage pipe, the drainage pipe can be prevented from being inserted too deeply. A rear end of the sliding sleeve 21 is provided with a fixing component 3 for fixing the sliding sleeve 21. The fixing component 3 includes a storage box 32 for supporting a slide plate 33 to move. The storage box 32 is fixedly connected to a rear end of the sliding sleeve 21.

[0031] Refer to Figure 1 - Figure 3, the connecting component 2 further includes a rubber sleeve 25 for sealing the left and right ends of the sliding sleeve 21. The left end of the rubber sleeve 25 is fixedly connected to the right end of the sliding sleeve 21. When the sliding sleeve 21 moves left and right, the rubber sleeve 25 will also move synchronously. The rubber sleeve 25 slides on the outer wall of the communicating pipe 1. A chute 23 for communicating the sliding sleeve 21 and the communicating pipe 1 is provided at the front end of the communicating pipe 1. A limiting ring 24 for restricting the movement track of the sliding sleeve 21 is fixedly connected to the rear end of the sliding sleeve 21. The limiting ring 24 slides on the inner wall of the chute 23. The limiting ring 24 can only slide on the inner wall of the chute 23. The fixing component 3 further includes a pressing ring 31 for pressing the rubber sleeve 25. The pressing ring 31 is made of plastic material and has the ability of elastic deformation. It can undergo elastic deformation when being pressed. The pressing ring 31 is fixedly connected to the outer wall of the rubber sleeve 25. The rear end of the pressing ring 31 is inserted into the inner wall of the storage box 32.

[0032] Refer to Figure 2 - Figure 4 , a sloping block 35 for driving the pressing ring 31 to merge is fixedly connected to the rear end of the pressing ring 31. The rear end of the sloping block 35 is provided with an inclined surface. When the inclined surface is pressed, the sloping block 35 will be forced to move inward. A sliding plate 33 for driving a trapezoidal block 36 to move is slidably connected to the rear end of the storage box 32. A trapezoidal block 36 for pressing the sloping block 35 is fixedly connected to the front end of the sliding plate 33. The trapezoidal block 36 and the sloping block 35 are adapted to each other. By using the trapezoidal block 36 to press the inclined surface of the sloping block 35, it can be forced to move inward. A threaded sleeve 37 for accommodating a bolt 34 is fixedly connected to the inner wall of the storage box 32. A bolt 34 for driving the sliding plate 33 to move is penetrated and rotatably connected to the rear end of the sliding plate 33. The bolt 34 is threadedly connected to the rear end of the threaded sleeve 37. By rotating the bolt 34, the sliding plate 33 can be driven to move back and forth. Multiple groups of rubber sleeves 25 and pressing rings 31 are provided. The multiple groups of rubber sleeves 25 and pressing rings 31 are symmetrically arranged with the center line of the sliding sleeve 21 as the axis of symmetry.

[0033] Working principle: When installing the whole device, the left and right ends of the communicating pipe 1 can be connected to the drainage pipeline by using a hydraulic press first. Then, the sliding sleeve 21 can be moved left and right to align the threaded head 22 with the water inlet pipeline. Then, the bolt 34 can be rotated to drive the sliding plate 33 to move forward. The forward movement of the sliding plate 33 will drive the trapezoidal block 36 to move synchronously. The movement of the trapezoidal block 36 will press the sloping block 35 to force the pressing ring 31 to bend and merge. The pressing ring 31 will press the rubber sleeve 25 to make it closely fit the outer wall of the communicating pipe 1. In this way, the sliding sleeve 21 will be fixed and unable to move. Then, the water inlet pipe and the threaded head 22 can be connected to each other.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
