Specific embodiment
As described below is only preferred embodiments of the present invention, and protection scope is not limited merely to the embodiment, all
The protection scope of the utility model should belong in the technical solution belonged under the utility model thinking.Simultaneously it should be pointed out that for
For those skilled in the art, several improvements and modifications without departing from the principle of the utility model, this
A little improvements and modifications also should be regarded as the protection scope of the utility model.
As shown in Figure 1, a kind of welding fixture for being suitable for 8 size and shape of HVAC pipe, including bracket 1 and bracket 22,
Bracket 1 is identical with the structure of bracket 22, and three medial surfaces of two brackets are equipped with several cylindrical bodies 1, each cylinder
Body 1 is vertically connect with bracket 1, and each one 11 outer surface of cylindrical body is cased with spring 1, and one end of spring 1 is fixed to be connected
It is connected to bracket 1, the other end fixation of spring 1 is connect with a bottom surface of open tubular column 1, and open tubular column 1 is set in circle
One 11 outer surface of cylinder, open tubular column can be covered to be slided on cylindrical body 1.
As shown in Fig. 2, being equipped with fixed mechanism between bracket 1 and bracket 22, fixed mechanism includes that bolt follows closely 31, iron chains
32 and convex block 33；Convex block 33 is equipped with through-hole one and extends 22 upper end of the bracket side opposite with bracket 1；One 1 upper end of bracket
The inside of the side opposite with bracket 22 is equipped with empty slot 34, and one 1 upper end of bracket is equipped with through-hole two, and through-hole two, which is worn, to be penetrated in empty slot 34
And through the top and bottom of the upper end of bracket 1, through-hole one and through-hole two are mutually aligned, and iron chains 32 is fixedly connected on bracket 1,
One end of iron chains 32 is equipped with bolt nail 31, and bolt nail 31 passes through through-hole two, the through-hole one of bracket 1, is pierced by after empty slot 34.
Round HVAC pipe 8(is referring to Fig. 1) it is fixed therein in left and right bracket 1 and bracket 22 are connected with each other, left and right branch
Spring 1 on frame 1 and bracket 22 is subject to extruding, and deformation occurs, and spring 1 is set on cylindrical body 1,
Compared with no cylindrical body 1, spring 1 is when being pressurized in addition to deformation occurs for length, it is not easy to crook, it is ensured that only
There is elastic potential energy in the longitudinal direction.Since the deformation that the shape of HVAC pipe 8 will lead to each generation of spring 1 is different,
Flexible length is also just different, and the shape of HVAC pipe 8 is adapted to so as to cause spring 1；On bracket 1 and bracket 22
The elastic potential energy that spring 1 in relative position has is contrary, and the function and effect of the power of formation will be HVAC pipe 8
