Detailed Description
The invention will be further described with reference to the following drawings and specific embodiments:
example (b):
referring to fig. 1, the present embodiment provides a fixing device for an air-entrapping connection of an outdoor switch yard circuit breaker, which includes a first flange 1 and a second flange 2; the middle parts of the first flange plate 1 and the second flange plate 2 are provided with air guide through holes along the axial direction; the two plane ends of the first flange plate 1 and the second flange plate 2 are oppositely arranged, and the two air guide through holes are communicated; the other ends of the first flange plate 1 and the second flange plate 2 are respectively provided with an air duct 3; the outer side walls of the first flange plate 1 and the second flange plate 2 are also detachably provided with a circular ring fixing sleeve 4; an annular mounting groove 5 matched with the first flange plate 1 and the second flange plate 2 in structural size is formed in the inner side wall of the annular fixing sleeve 4. In this embodiment, the depth of the annular mounting groove 5 is the difference between the outer diameter of the flange and the inner diameter of the annular fixing sleeve 4.
The outer diameters of the flanges on the first flange plate 1 and the second flange plate 2 are the same. The ring flange of the same external diameter size is in order to reduce the processing degree of difficulty of annular mounting groove in the fixed cover 4 of ring, and need not to set up in advance its positive and negative when the fixed cover 4 of installation ring, and it is more convenient to assemble.
The ring fixing sleeve 4 is made of a hard structure made of copper or stainless steel materials. The ring fixing sleeve 4 with the hard structure is formed by enclosing two arc plates 41 with semicircular structures, a connecting plate 42 is arranged at the end sides of the two arc plates 41, and the two arc plates 41 are movably connected at the connecting plate 42 through a hinge rod 43. The arc-shaped plate 41 with the two-section structure can rotate to separate or close through the hinge rod 43 at the position of the connecting plate 42 during disassembly and assembly, so that the operation is more convenient.
The two arc plates 41 are provided with tenon-and-mortise structures 44 which are matched with each other on the sides where the connecting plates 42 are not arranged. The mortise and tenon structure 44 is used for ensuring that the connection side is effectively fixed and preventing the connection side from being separated.
A torsion spring is further arranged on the hinge rod 43, and two ends of the torsion spring are respectively fixed on the two connecting plates 42. In this embodiment, the torsion spring is not shown, but the other side of the arc plate 41 is closed when the torsion spring is in a natural state. The device can be kept closed in the rest state by means of a torsion spring.
