As shown in Figures 2 and 3, the outside of frame 40 has snap groove 41; Heat collector cases connects the snapping head 22 that has protrusion on the cover plate 20; Have snapping head 31 and snap groove 33 on the elasticity connecting plate 30.Snap groove 41 snappings of snapping head 31 on the elasticity connecting plate 30 and frame 40, heat collector cases connect on the cover plate 20 snapping head 22 again with elasticity connecting plate 30 on snap groove 33 snappings, thereby make heat collector cases connect cover plate 20 adjacent frame 40 is coupled together, the while is pressed on external seal bar (as among Fig. 1 2) on the euphotic cover plate on the frame 40 (as among Fig. 1 1).
In the present embodiment, elasticity connecting plate 30 is made by spring steel, the middle buffer strip 34 that falls " Ω " tee section that also has elastically deformable.Under the nature elongation state, the spacing of the openend of buffer strip 34 is D.
When exerted pressure in the two ends of elasticity connecting plate 30, buffer strip 34 can produce elastic shrinkage, and the space D of its openend diminishes gradually, even is zero; The distance that the snapping head at elasticity connecting plate 30 two ends is 31 is also done corresponding variation; This moment, elasticity connecting plate 30 was that [D, 0] is with interior snapping applicable to two adjacent edge frame range deviations.
When the two ends to elasticity connecting plate 30 applied pulling force, buffer strip 34 can produce elastic stretch, and the space D of its openend increases gradually; The distance that the snapping head at elasticity connecting plate 30 two ends is 31 is also done corresponding variation; This moment, elasticity connecting plate 30 was the snapping of timing applicable to two adjacent edge frame range deviations.Certainly, the maximum of above-mentioned overgauge should be in the elastic deformation limit of buffer strip 34.
Therefore, when the processing of heat collector cell cube, adjacent frame, when the certain deviation of appearance is installed, elasticity connecting plate 30 with buffer strip 34 still can connect adjacent frame, thereby reduced heat collector cell cube, the processing of adjacent frame, installation requirement, saved processing, the installation cost of solar thermal collector then.
In the present embodiment, the snapping head 31 of elasticity connecting plate 30 has the square-section; The cross section of the snap groove 41 of frame 40 is outwards-upwards-the inside circular arc that stretches, promptly snap groove 41 is the setting limit formation 3/4 above enclosed areas of circular arc and frame 40.Side direction promotes elasticity connecting plate 30, pack into the snap groove 41 of frame 40 of its snapping head 31.The snap groove 41 of frame 40 stops that by the restriction of its edge make-up joint 31 snapping head 31 is come off by the periphery of snap groove 41, promptly forms locking.
In the present embodiment, snapping head 31 tops of elasticity connecting plate 30 also have snap groove 32.When the snapping head 31 of elasticity connecting plate 30 was packed the snap groove 41 of frame 40 into, the circular arc on the cross section of the snap groove 41 of frame 40 also snapped in the snap groove 32 of snapping head 31 tops of elasticity connecting plate 30 simultaneously.The edge of the snap groove 41 of 32 pairs of frames 40 of snap groove of elasticity connecting plate 30 also forms locking.
Therefore, when elasticity connecting plate 30 was connected with adjacent frame, elasticity connecting plate 30 and frame 40 formed two-way locking.That is to say, elasticity connecting plate 30 is difficult to from frame 40 taking-ups, can only be elasticity connecting plate 30 to be applied the thrust of side direction, and can not be vertically to extract.This design has increased the difficulty of the random dismounting heat collector of non-heat collector installation personnel, thus the unnecessary trouble of having avoided any dismounting heat collector to cause.
Among the embodiment as shown in Figure 4 and Figure 5, the buffer strip of elastically deformable is to be positioned at the snapping head 31 that the snap groove 41 of the two ends of elasticity connecting plate 30 and frame 40 is interlockingly connected.The snapping head 31 of elasticity connecting plate 30 and snap groove 33 are with a part, the internal cavities of this part is that elasticity connecting plate 30 is connected the snap groove 33 that the snapping head 22 of cover plate is interlockingly connected with heat collector cases, and the outside frame of this part is the snapping head 31 that the snap groove 41 of elasticity connecting plate 30 and frame 40 is interlockingly connected; When elasticity connecting plate 30 was in the nature elongation state, the outside of the inner edge of the snapping head 31 of elasticity connecting plate 30 and the snap groove 41 of frame 40 had clearance D 1.
The snapping head 31 of elasticity connecting plate 30 has the square-section; The cross section of the snap groove 41 of frame 40 is outwards-upwards-the inside circular arc that stretches, promptly snap groove 41 is the setting limit formation 3/4 above enclosed areas of circular arc and frame 40.Side direction promotes elasticity connecting plate 30, pack into the snap groove 41 of frame 40 of its snapping head 31.The snap groove 41 of frame 40 stops that by the restriction of its edge make-up joint 31 snapping head 31 is come off by the periphery of snap groove 41, promptly forms locking.
When exerted pressure in the two ends of elasticity connecting plate 30, the snapping head 31 at two ends all moves in snap groove 41 inwards, clearance D 1 between the outside of the inner edge of snapping head 31 and snap groove 41 diminishes gradually, even is zero, causes that directly the distance of 31 on the snapping head at elasticity connecting plate 30 two ends shortens; This moment, elasticity connecting plate 30 was that [2D1,0] is with interior snapping applicable to two adjacent edge frame range deviations.Obviously, if embodiment is identical with adjustable frame range deviation in the present embodiment before making, the clearance D value among the preceding embodiment can be about 2 times of present embodiment intermediate gap D1.
When the processing of heat collector cell cube, adjacent frame, when the certain deviation of appearance is installed, elasticity connecting plate 30 with two ends buffer strip still can connect adjacent frame, thereby reduced heat collector cell cube, the processing of adjacent frame, installation requirement, saved processing, the installation cost of solar thermal collector then.
Among the embodiment as shown in Figure 6 and Figure 7, described elasticity connecting plate 30 had both had the buffer strip of the elastically deformable that is positioned at its two ends, had the buffer strip that is positioned at its middle elastically deformable again.
When exerted pressure in the two ends of elasticity connecting plate 30, middle buffer strip 34 can produce elastic shrinkage, and the space D of its openend diminishes gradually, even is zero; The buffer strip at while elasticity connecting plate 30 two ends, promptly snapping head 31 all moves in snap groove 41 inwards, and the clearance D 1 between the outside of the inner edge of snapping head 31 and snap groove 41 diminishes gradually, even is zero.Above-mentioned two ends and intermediate buffering band cause the variable in distance of 31 on the snapping head at elasticity connecting plate 30 two ends jointly; This moment, elasticity connecting plate 30 was that [(D+D1), 0] is with interior snapping applicable to two adjacent edge frame range deviations.
When the two ends to elasticity connecting plate 30 applied pulling force, middle buffer strip 34 can produce elastic stretch, and the space D of its openend increases gradually; The distance that the snapping head at elasticity connecting plate 30 two ends is 31 is also done corresponding variation; This moment, elasticity connecting plate 30 was the snapping of timing applicable to two adjacent edge frame range deviations.Certainly, the maximum of above-mentioned overgauge should be in the elastic deformation limit of buffer strip 34.
