[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1 to 7 As shown, a thin-walled stainless steel pipe connector includes a thin-walled stainless steel pipe 1, a circular groove 11 is provided on the right side of the thin-walled stainless steel pipe 1, a thin-walled stainless steel pipe 2 is snapped into the right side of the circular groove 11, a rubber ring gasket 4 is sleeved between the thin-walled stainless steel pipe 1 and the thin-walled stainless steel pipe 2, and a first clamping arc plate 5 is fixedly provided on the lower side of the rubber ring gasket 4.

[0029] A second clamping arc plate 6 is rotatably installed inside the first clamping arc plate 5. Through the installation and use of the first clamping arc plate 5 and the second clamping arc plate 6, the two clamping arc plates can be used to squeeze and position the rubber ring gasket 4 to form a connector, so that the thin-walled stainless steel tube 1 and the thin-walled stainless steel tube 2 can be connected and reinforced, improving the stability of the thin-walled stainless steel tube. Two movable protrusions 7 for fixing the first clamping arc plate 5 are slidably connected to the inner side of the second clamping arc plate 6. A first spring 8 is fixedly connected between the two movable protrusions 7 and the second clamping arc plate 6. A first positioning rod 3 is arrayed and connected to one side of the inside of the thin-walled stainless steel tube 1. An array of positioning holes 12 are opened inside the thin-walled stainless steel tube 1. A second positioning rod 10 is snapped into the inside of the positioning holes 12. Through the installation and use of the first positioning rod 3 and the second positioning rod 10, the two can be snapped into each other to position the thin-walled stainless steel tube 1 and the thin-walled stainless steel tube 2, ensuring the connection effect of the two thin-walled stainless steel tubes.

[0030] The outer surface of the thin-walled stainless steel tube 1 is fixedly provided with an adapter plate 13 and an adapter plate 2 14. The adapter plate 2 14 is located below the adapter plate 13. An array of second springs 15 are fixedly installed between the adapter plate 13 and the adapter plate 2 14. The left side of the adapter plate 13 is slidably engaged with two L-shaped insert plates 16 for fixing the first clamping arc plate 5 and the second clamping arc plate 6. One side of the first clamping arc plate 5 and the second clamping arc plate 6 is threaded with a fastening bolt 17 for fixing the L-shaped insert plate 16. By setting the fastening bolt 17, rotating the fastening bolt 17 can compress and fix the L-shaped insert plate 16. In this way, the two L-shaped insert plates 16 can be used to firmly reinforce the installation of the two thin-walled stainless steel tubes.

[0031] Both the first adapter plate 13 and the second adapter plate 14 have two threaded rods 18 threadedly connected to their right sides. Each of the four threaded rods 18 has a pin 19 fixedly connected to one side for fixing the first clamping arc plate 5 and the second clamping arc plate 6. The left sides of the first clamping arc plate 5 and the second clamping arc plate 6 each have two circular grooves 67 that are adapted to the pins 19. The right side of the pin 19 is engaged with the left side of the first clamping arc plate 5 and the second clamping arc plate 6 through the circular grooves 67.

[0032] The left side of both the first clamping arc plate 5 and the second clamping arc plate 6 is provided with a slot 66, which is adapted to the L-shaped insert plate 16. The right side of the L-shaped insert plate 16 is respectively engaged with the first clamping arc plate 5 and the second clamping arc plate 6 through the slot 66.

[0033] The left side of the thin-walled stainless steel tube 2 is located inside the thin-walled stainless steel tube 1. One side of the movable protruding rod 7 passes through the second clamping arc plate 6 and extends to one side of the second clamping arc plate 6. A connecting plate 9 is fixedly installed on one side of each of the two movable protruding rods 7. The right side of the second positioning rod 10 is connected to the left side of the thin-walled stainless steel tube 2. By setting the connecting plate 9, moving the connecting plate 9 can drive the elastic movable protruding rod 7 away from the first clamping arc plate 5, so as to remove the two clamping arc plates and disassemble the thin-walled stainless steel tube, which is convenient to use.

[0034] The first clamping arc plate 5 has grooves 68 at both ends. The grooves 68 are adapted to the movable protrusions 7. The outer surface of the movable protrusions 7 is slidably engaged with the two ends of the first clamping arc plate 5 through the grooves 68.

[0035] The working principle of the thin-walled stainless steel pipe connector provided by this utility model is as follows:

[0036] By snapping the thin-walled stainless steel tube 2 into the interior of the thin-walled stainless steel tube 1, the first positioning rod 3 and the second positioning rod 10 can play a preliminary positioning role to connect the two thin-walled stainless steel tubes. Then, the rubber ring gasket 4 is fitted onto the connection between the thin-walled stainless steel tube 1 and the thin-walled stainless steel tube 2. Next, the first clamping arc plate 5 and the second clamping arc plate 6 are snapped onto the rubber ring gasket 4. Then, the two connecting plates 9 are pulled to cause the two movable protrusions 7, which are equipped with the first spring 8, to retract. Then, the two connecting plates 9 are released, so that the two movable protrusions 7 with elasticity can automatically extend and snap onto the first clamping arc plate 5 for fixation. At this time, the first clamping arc plate 5 and the second clamping arc plate 6 can be used to snap onto and fix at the connection. This snap-fit ​​method makes it easy to install and remove the thin-walled stainless steel tube and inspect its interior, improving the convenience of assembling the thin-walled stainless steel tube.

[0037] By elastically attaching the adapter plate 13 and adapter plate 24, both equipped with the second spring 15, to the outer surface of the thin-walled stainless steel tube 1, and then pushing the L-shaped inserts 16 on the adapter plate 13 and adapter plate 24 into the slots 66 of the first clamping arc plate 5 and the second clamping arc plate 6 respectively, the two clamping arc plates are further clamped and fixed. Then, the four threaded rods 18 are rotated in sequence, so that the four threaded rods 18 can drive the four pins 19 to be inserted into the first clamping arc plate 5 and the second clamping arc plate 6, which is conducive to the stable positioning of the first clamping arc plate 5 and the second clamping arc plate 6. At this time, the thin-walled stainless steel tube 1 and the thin-walled stainless steel tube 2 can be stably connected together, and are not easy to loosen or leak.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
