Heating radiator buckle cap and buckle

Abstract

Disclosed are a buckle cap and a buckle of a heating heat radiator. The heating heat radiator comprises the buckle caps and the buckles, and at least two buckles are matched with each buckle cap. The buckle cap is of columnar thin wall structure, wherein one side of the buckle cap, which is parallel to the axis of the buckle cap, is open, an installation groove parallel to the axis of the buckle cap is formed in the inner wall of the buckle cap, which directly faces the open side of the buckle cap, two L-shaped structures are formed on the cross section of the installation groove, openings of the two L-shaped structures are opposite, and structures protruded inward are formed on two side walls of the open side of the buckle cap. The buckle comprises a T-shaped connection portion, a curved surface containing portion protruded outward and collapsing support portions. When the buckle cap and the buckle are assembled, the T-shaped connection portion of the buckle is inserted into the installation groove of the buckle cap, and then a cavity communication pipe passes through the buckle. The cavity communication pipe is fixed in the buckle in clamping mode due to the fact that the clearance distance between two adjacent collapsing support portions is smaller than the diameter of the cavity communication pipe, and simultaneously the lower edges of the collapsing support portions are pressed against a bulge of the buckle cap, and therefore the curved surface containing portion can not be unfolded even when the buckle bears a certain load.

Description

[0001] Technical field: [0002] The invention relates to the technical field of heating radiators, in particular to a heating radiator cap and buckle. [0003] Background technique: [0004] Such as figure 1 , figure 2 As shown, there is currently a class of heating radiators whose structure includes: external cooling fins 11, buckle caps 12, internal cavity tubes 13, and cooling tubes; the internal space of cooling fins 11 is provided with a row of parallel cooling tubes. The two ends of the cooling pipe are in communication with the tube wall of the joint cavity tube 13, and the joint cavity tube 13 is covered with a buckle cap 12, and the lower edge of the buckle cap 12 is in contact with the cooling fins 11. [0005] In the current technology, the buckle cap 12 is mainly kept fixed with the multi-lumen tube 13 through its inner structure, and must have a certain degree of firmness. In the existing design, either the structure is too complicated, which increases the dif...

AI Technical Summary

Problems solved by technology

In the existing design, either the structure is too complicated, which increases the difficulty of the process, or the connection between the buckle cap 12 and the multi-cavity tube 13 is loose, and it is easy to fall off
