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 present invention provides a technical solution: a baffle with an expansion joint structure comprises a baffle body 1, wherein mounting bolt holes 2 are respectively formed in two sides inside the baffle body 1, expansion joints 3 are respectively formed in two sides of the top of the baffle body 1, the expansion joints 3 are arranged at two ends or the middle position of the baffle body 1, the expansion joint 3 structure is a material with a certain shape removed from the baffle body 1, so that the expansion joint 3 is weaker than the other parts of the baffle body 1 in strength and is easier to deform, the expansion joint 3 is formed by combining two V-shaped notches which are in central symmetry, a triangular notch is formed in the top of a V-shaped sharp point of the expansion joint 3, so that the expansion joint 3 is easier to deform during brazing of a core assembly, the heat and cold of the baffle body 1 are effectively absorbed, movable grooves 4 are respectively formed in two sides inside the baffle body 1, and movable plates 5 are respectively connected inside the two movable grooves 4 in a sliding manner, adopt transition fit between the surface of fly leaf 5 and the inner wall of activity groove 4, and the bottom of fly leaf 5 contacts with the top of construction bolt hole 2, one side fixedly connected with movable rod 6 of fly leaf 5, movable rod 6 extends to the outside one end fixedly connected with movable block 8 of activity groove 4, and the through-hole 9 with movable rod 6 looks adaptation is seted up to the inside of baffle body 1, and the one end of movable rod 6 runs through activity groove 4 and extends to the outside of activity groove 4, one side fixedly connected with spring 7 of activity groove 4 inner wall, the internal surface of spring 7 and the surface sliding connection of movable rod 6, and the one end of spring 7 and one side fixed connection of fly leaf 5, the content that does not make detailed description in this specification all belongs to the prior art that skilled person publicly knows simultaneously.
