Abstract
The utility model relates to a fast connecting buckle for a pressure-bearing heat collector, which is composed of two half circular arc-shaped connecting buckles and a bolt, wherein, the inner wall of each of the connecting buckles is concave and U-shaped. Both ends of the outer wall of each of the connecting buckles are respectively provided with one connecting lug. The connecting lug is provided with a screw hole for connection. The axial cord of the screw hole for connection is mutually vertical with the axial cord of a pipeline. A gap S is arranged between the two half circular arc-shaped connecting buckles which are assembled into one connecting buckle. The concave shape of the inner wall of each of the connecting buckles is a U-shaped shape. The cross-section of the U-shaped part comprises a isosceles trapezoid or a circular arc. With the connecting buckle, the pipeline can be connected fast. The utility model has the advantages of beautiful appearance, good tightness, firm connection and convenient operation.
Description
Technical field: the utility model relates to the quick connection fastener of a kind of pressure-bearing type heat collector.
Background technique: the prior solar water heater heat collector connects the clip connecteds of adopting more, and its poor sealing, profile are not attractive in appearance, and be not very long working life.China utility model patent CN2449152Y, name is called " solar energy water heater pipe linkage structure ", a kind of linkage structure of solar energy water heater pipe is disclosed, it is made up of flange, seal ring and fastening piece, and both sides cover upper flange, therebetween seal ring are fixed by fastening piece during connection, but this Placement needs to put in advance adpting flange in pipeline, its profile is not too attractive in appearance, connects poor sealing, and it is also not too convenient to use.
Summary of the invention: the utility model purpose provides the quick connection fastener of a kind of pressure-bearing type heat collector, uses this connection fastener, can fast, directly block pipeline, connecting tube, its beautiful shape, good airproof performance, be connected firmly, easy to use.
The purpose of this utility model is achieved in that the quick connection fastener of a kind of pressure-bearing type heat collector, it is characterized in that connection fastener is made of two semi-circle junction buttons and bolt, the inwall of junction button is concavity " U " shape, respectively there is an engaging lug at the outer wall two ends of junction button, have on the engaging lug to connect and use screw, connect with the axis of screw vertical mutually with conduit axis; Be combined as between two semi-circle junction buttons of a connection fastener and have gap S; Junction button inwall concavity is " U " shape shape, and the cross section of " U " shape shape comprises isosceles trapezoid or circular arc.
During use, the quick connection fastener of the utility model pressure-bearing type heat collector directly is buckled in two sections mouth of pipe places, with bolt () fastening.Owing to having gap S between two semi-circle junction buttons that are combined as a connection fastener; Make its inwall produce a compaction forces, press pad (6), press the flanging that pad (6) is pressed to the pipeline opening place again, flanging compresses O-ring seal (4) again, quick connecting pipe road the most at last, the utility model fastener thereby have only good airproof performance connects advantage reliable, easy to use.
Description of drawings: below in conjunction with the accompanying drawing illustrated embodiment, be described further with regard to the utility model.But protection domain is not limited to embodiment.
Fig. 1 is the structural representation of the quick connection fastener connecting tube of the utility model pressure-bearing type heat collector.
Fig. 2 is that the quick connection fastener of the utility model pressure-bearing type heat collector connects plug structural representation view.
Fig. 3 is the right elevation of the quick connection fastener of pressure-bearing type heat collector shown in Figure 1.
Embodiment: according to the Figure 1 and Figure 2 structure, make the quick connection fastener of pressure-bearing type heat collector, the inwall of semi-circle junction button (1) is that " U " shape shape is selected isosceles trapezoid.
During use, between the mouth of pipe of the two aluminium pipe pipelines (3) that needs connect, put into cushion rubber sealing together (4), respectively put one at place, tube road junction, connection fastener (1) inwall " U " type cross section and press pad (6), and place two mouth of pipe sidepieces, with two 2 screw 5 that " U " matrix 1 links to each other in bolt on and 7 get final product.
1-semi arch junction button; The 2-engaging lug; The 3-pipeline; The 4-O-ring seal; The 5-screw; 6-presses pad; The 7-bolt; S-is combined as between two semi arch junction buttons (1) of a connection fastener has the gap.
Claims (3)
1, the quick connection fastener of a kind of pressure-bearing type heat collector, it is characterized in that connection fastener is made of two semi-circle junction buttons (1) and bolt (7), the inwall of junction button (1) is concavity " U " shape, respectively there is an engaging lug (2) at the outer wall two ends of junction button (1), have on the engaging lug (2) to connect and use screw (5), connect with the axis of screw (5) vertical mutually with pipeline (3) axis.
