Specific implementation manners

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-3 , the embodiments of the present utility model provide a technical solution: a quick connection structure for stainless steel pipes, including a device body 1. The device body 1 includes a first stainless steel pipe 2, a second stainless steel pipe 3 and a locking device 4. The first stainless steel pipe 2 is installed at the rear end of the second stainless steel pipe 3. There are two groups of the locking devices 4, and the two groups of the locking devices 4 are symmetrically installed on the first stainless steel pipe 2 and the second stainless steel pipe 3 respectively;

[0020] It is solved that embedding sleeves 5 are provided at the rear ends of the first stainless steel pipe 2 and the second stainless steel pipe 3. The first stainless steel pipe 2, the second stainless steel pipe 3 and the embedding sleeve 5 have a smooth transition and are integrally formed. Two sets of sliding grooves 6 are arranged in a ring-shaped and equally spaced manner inside the embedding sleeve 5, and two sets of limiting notches 7 are arranged in a ring-shaped and equally spaced manner at the front end of the embedding sleeve 5.

[0021] Furthermore, connection cylinders 8 are provided at the front ends of the first stainless steel pipe 2 and the second stainless steel pipe 3. Two sets of sliding limiting blocks 9 are arranged on the front surface of the connection cylinder 8 in a ring-shaped and equally spaced manner. When installing the first stainless steel pipe 2 behind the second stainless steel pipe 3, the staff inserts the connection cylinder 8 of the first stainless steel pipe 2 into the embedding sleeve 5 of the second stainless steel pipe 3. Then, the sliding limiting blocks 9 of the connection cylinder 8 will align with the sliding grooves 6 of the embedding sleeve 5 and slide in, and then slide into the front end of the embedding sleeve 5. The staff rotates the first stainless steel pipe 2 (at this time, it is also necessary to ensure that the locking device 4 on the first stainless steel pipe 2 and the second stainless steel pipe 3 is aligned after rotation), so that the sliding limiting blocks 9 of the connection cylinder 8 are embedded into the limiting notches 7 of the embedding sleeve 5 to achieve the purpose of limiting and locking.

[0022] Differently, the locking device 4 includes a support column 10 and a threaded ring 11. The support column 10 and the threaded ring 11 have a smooth transition and are integrally formed. The support column 10 is located at the bottom of the threaded ring 11. An adjusting locking bolt 12 is installed inside the threaded ring 11. When locking the first stainless steel pipe 2 and the second stainless steel pipe 3 again, the staff inserts the adjusting locking bolt 12 into the threaded ring 11 of the first stainless steel pipe 2, and then rotates the adjusting locking bolt 12 to connect it with the threaded ring 11 of the second stainless steel pipe 3. In this way, the first stainless steel pipe 2 and the second stainless steel pipe 3 can be fixed.

[0023] Working principle: During operation, when installing the first stainless steel pipe 2 behind the second stainless steel pipe 3, the staff inserts the connecting cylinder 8 of the first stainless steel pipe 2 into the embedding sleeve 5 of the second stainless steel pipe 3. Then, the sliding limit block 9 of the connecting cylinder 8 will align with the sliding groove 6 of the embedding sleeve 5 and slide in, and then slide into the front end of the embedding sleeve 5. The staff rotates the first stainless steel pipe 2 (at this time, it is also necessary to ensure that the locking device 4 on the first stainless steel pipe 2 and the second stainless steel pipe 3 is aligned after rotation), so that the sliding limit block 9 of the connecting cylinder 8 is embedded in the limit notch 7 of the embedding sleeve 5 to achieve the purpose of limiting and locking. When locking again between the first stainless steel pipe 2 and the second stainless steel pipe 3, the staff inserts the adjusting locking bolt 12 into the threaded ring 11 of the first stainless steel pipe 2, and then rotates the adjusting locking bolt 12 to connect the adjusting locking bolt 12 with the threaded ring 11 of the second stainless steel pipe 3. In this way, the first stainless steel pipe 2 and the second stainless steel pipe 3 can be fixed.
