The present application is described in further detail below with reference to figures 1-10.

The embodiment of the application discloses high-efficient heat preservation connection return bend, as shown in fig. 1 and 2, including first connection return bend 1, equal fixedly connected with annular protrusion 11 of 1 outer wall both ends position department of first connection return bend. The two ends of the first connecting bent pipe 1 are respectively clamped with a second connecting bent pipe 12 corresponding to the positions of the annular protrusions 11, the inner wall of each second connecting bent pipe 12 is provided with a clamping groove 13 close to the positions of the annular protrusions 11, and the second connecting bent pipes 12 are clamped in the first connecting bent pipes 1 through the clamping grooves 13.

As shown in fig. 1 and 3, rectangular sliding blocks 2 are disposed at two ends of the first connecting elbow 1 corresponding to the positions of the annular protrusions 11. First through-hole 21 has been seted up to sliding block 2, and first through-hole 21 sets up along the direction of height of sliding block 2. The sliding block 2 is connected with two racks 22 in the first through hole 21, and the racks 22 slide along the height direction of the sliding block 2. A gear 23 is engaged between the two racks 22 at the center of the slide block 2. Each rack 22 is away from each other, one end of each rack is fixedly connected with a semicircular top connection plate 24, one side of each top connection plate 24, which is away from the rack 22, is fixedly connected with an elastic rubber belt 241 (refer to fig. 4), and the rubber belt 241 can abut against the position of the annular protrusion 11 corresponding to the inner wall of the first connection elbow 1. Each rack 22 is far away from one side and is provided with a plurality of rolling grooves 221, the rolling grooves 221 are formed in the positions, close to the gear 23, of the racks 22, and the rolling grooves 221 are arranged in an array mode along the length direction of the racks 22. Each rack 22 is rotatably connected with a ball 222 in each rolling groove 221, and the ball 222 can abut against the sliding block 2 (refer to fig. 5). The two racks 22 are provided with positioning grooves 25 at positions corresponding to positions between every two rolling grooves 221 at sides far away from each other. The central positions of the two ends of the sliding block 2 are both provided with positioning through holes 26, and the longitudinal sectional area of each positioning through hole 26 is equal to that of the positioning groove 25. Slide block 2 corresponds and has all pegged graft in every positioning hole 26 and has had locating lever 261, and locating lever 261 can stretch into in the constant head tank 25 that rack 22 corresponds.
