Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the utility model provides an H-type finned tube that can avoid collision, including base tube 1, the connecting tube ring 2 of difference symmetric connection at base tube 1 both ends and evenly set up a plurality of fins 3 in base tube 1 periphery.

The both sides of the tip symmetry of parent tube 1 are equipped with a parent tube recess 11 respectively, and fixedly connected with first spring 12 in the parent tube recess 11, the end connection of first spring 12 has a movable block 13, and movable block 13 can follow parent tube recess 11 and remove. During the use, under the effect of pressure, the first spring 12 of movable block 13 compression can be located parent tube recess 11 completely, treats that pressure disappears the back, under the elastic force effect of first spring 12, and movable block 13 is outstanding to the surface of parent tube 1 in following parent tube recess 11.

A pipe ring groove 21 has been seted up respectively to the inner wall of the symmetry of connecting pipe ring 2, has seted up spout 22 in the pipe ring groove 21, and mating connection has a slider 23 in the spout 22, and one side of slider 23 is connected with second spring 24, and the tip fixed connection of second spring 24 is on the inner wall of pipe ring groove 21, slider 23 and the end connection of parent tube 1. During the use, when fin 3 received external force striking, base tube 1 just removed to corresponding direction, and at this moment, slider 23 removes and compresses second spring 24 along spout 22, and second spring 24 compression produces the resilience force, cushions the impact force, avoids fin 3 to receive the damage.

Specifically, the sliding grooves 22 are arranged in a pair, the sliding grooves are respectively symmetrically located on two sides of the pipe ring groove 21, two ends of the sliding block 23 are respectively connected into the sliding grooves 22, stability of the sliding block 23 when moving along the sliding grooves 22 is facilitated, and working stability of the H-shaped finned tube is guaranteed.

Specifically, the slider groove 231 has been seted up to the one end of slider 23 towards base tube 1, and slider groove 231 and the size looks adaptation of movable block 13. In use, the movable block 13 is received in the slider groove 231, thereby connecting the base pipe 1 and the connection pipe ring 2 together.

Specifically, the inner wall of the side of the base pipe 1 far away from the connecting pipe ring 2 is provided with an annular limiting block 25, and the side surface of the limiting block 25 and the inner wall of the connecting pipe ring 2 form an annular groove 26. When the base pipe is used, the end part of the base pipe 1 is accommodated in the annular groove 26, the side surface of the end part of the base pipe 1 is tightly attached to the side surface of the limiting block 25, and the movable block 13 is accommodated in the sliding block groove 231. The limiting block 25 is arranged, so that the base tube 1 and the connecting tube ring 2 can be connected together quickly and accurately. The inner diameter of the limiting block 25 is equal to that of the base pipe 1, so that the high-temperature medium can circulate in the base pipe 1 and the connecting pipe ring 2 at a relatively uniform speed.

The working principle is as follows: the parent tube 1 that will be connected with fin 3 is connected with connecting tube ring 2, and when fin 3 received external force striking, parent tube 1 just removed to corresponding direction, and at this moment, slider 23 removed and compressed second spring 24 along spout 22, and second spring 24 compression produces the resilience force, cushions the impact force, avoids fin 3 to receive the damage.
