[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example

[0024] See also Figures 1 to 4 , is an embodiment of the utility model, which provides a technical solution: a metal telescopic tube, comprising

[0025] A stainless steel pipe 1 installed on the reflux pump 4 and a stainless steel pipe 2 installed on the reflux box 5, wherein the left end of the stainless steel pipe 2 is movably located inside the stainless steel pipe 1;

[0026] and a snap-fit ​​adjustment mechanism 3 disposed between the stainless steel tube 1 and the stainless steel tube 2, comprising a U-shaped base 31 fixed on the top surface of the stainless steel tube 1, a movable notch 32 provided on the surface of the U-shaped base 31, an movable clamping plate 33 movably installed in the movable clamping plate 33 and with the right end extending to the top of the stainless steel tube 2, a limit clamping block 34 welded and fixed to the bottom surface of the movable clamping plate 33, and a plurality of limit clamping grooves 35 provided on the top surface of the stainless steel tube 2;

[0027] and a guide structure disposed between the stainless steel pipe 1 and the stainless steel pipe 2;

[0028] And a sealing structure is arranged at the inner end of the stainless steel pipe 2.

[0029] The snap-fit ​​adjustment mechanism 3 further includes two guide rods 37 welded and fixed on the top surface of the movable clamping plate 33. The top ends of the two guide rods 37 extend through the top of the U-shaped base 31. The bottom end surface of the guide rods 37 is sleeved with a spring 36 relative to the inner side of the movable notch 32. Under the push of the spring 36, the limit block 34 at the bottom of the movable clamping plate 33 can be stably clamped in the limit slot 35 to ensure the limit stability of the stainless steel pipe 2. When it is necessary to adjust the length of the entire metal telescopic tube in the later stage, it is only necessary to lift the movable clamping plate 33 with force, so that the guide rods 37 move up with the top plate 38, and make The spring 36 is gradually compressed, so that the limit block 34 can be moved out of the limit slot 35, thereby releasing the limit between the stainless steel pipe 1 and the stainless steel pipe 2. At this time, the stainless steel pipe 1 and the stainless steel pipe 2 can be telescopically adjusted. When the whole is adjusted to a suitable length, the movable clamping plate 33 is released. Under the push of the spring 36, the movable clamping plate 33 rebounds with the limit block 34 and resets, and the limit block 34 is stuck in the limit slot 35 at another position, so that the stainless steel pipe 2 can be limited again, thereby completing the overall length adjustment step. The overall adjustment step is simple and fast, saving time and effort.

[0030] The top surface of the U-shaped base 31 is provided with two rod holes communicating with the movable notch 32 , and the rod holes correspond to the guide rod 37 so that the guide rod 37 can pass through smoothly.

[0031] The top end of the spring 36 abuts against the top inner wall of the movable notch 32 , and the bottom end of the spring 36 abuts against the top surface of the movable clamping plate 33 .

[0032] A top plate 38 is further disposed on the top surface of the U-shaped base 31 , and top ends of the two guide rods 37 are fixed to the top plate 38 , so that the top plate 38 can be lifted and lowered together with the two guide rods 37 .

[0033] Among them, the guiding structure includes a strip guide block 11 fixed on the inner wall of the stainless steel tube 1 and a strip guide groove 21 opened on the bottom surface of the stainless steel tube 2. The strip guide block 11 is slidably located in the strip guide groove 21, so that the stainless steel tube 1 and the stainless steel tube 2 will not rotate during the telescopic adjustment process, ensuring that the limit slot 35 can always be aligned with the limit block 34.

[0034] Among them, the sealing structure includes a sealing ring 6 installed on the left end of the stainless steel pipe 2, and the surface of the sealing ring 6 is provided with a plurality of integrated annular sealing protrusions 61, both of which are made of fluororubber material and will undergo elastic deformation when squeezed. The plurality of annular sealing protrusions 61 are all in close contact with the inner wall of the stainless steel pipe 1, and can form a plurality of annular sealing measures to ensure the sealing of the connection between the stainless steel pipe 1 and the stainless steel pipe 2. The right end of the sealing ring 6 extends into the inner side of the stainless steel pipe 2, and the right end surface of the sealing ring 6 is provided with a plurality of integrated T-shaped clamps 62, which are also made of fluororubber material and will undergo elastic deformation when squeezed. The inner wall of the left end of the stainless steel pipe 2 is provided with a plurality of T-shaped clamping grooves 22 for the T-shaped clamping heads 62 to be clamped, so that the sealing ring 6 can be stably clamped at the left end of the stainless steel pipe 2 and move laterally with the stainless steel pipe 2.
