Abstract
The utility model discloses a matching structure of a rotation isolating switch shaft head and end beam, which comprises an end beam (5), a shaft head (6), and a retaining gear (4) and a crankarm (2) which are fastened on the shaft head 6, wherein a shaft sleeve (8) is fastened on the end beam (5), the shaft head (6) is movably matched in the shaft sleeve (8), and can freely rotate in the shaft sleeve (8). When operating forces are exerted on the crankarm (2), the shaft head (6) is driven to rotate through rotating the crankarm (2), and the radial component force of the operating force on the shaft head can not lead the shaft head (6) to swing as the shaft sleeve (8) is tightly matched on the end beam (5), and the shaft head (6) only can rotate, thereby strengthening the stability of a whole shaft.
Description
Technical field
The utility model relates to a kind of rotary isolation switch, and is special relevant with the fit structure of rotary isolation switch rotating shaft spindle nose and underframe end carriage.
Background technology
Rotary isolation switch is to isolate, connect, changing the device of getting in touch between electrified body and the electrical equipment under the non-loaded state of circuit in the electrical power distribution system.Stability when the correctness of rotary isolation switch operation and rotary isolation switch operation is the guarantee of electrical power distribution system safe handling.Rotary isolation switch rotates on the end carriage of underframe by the rotating shaft spindle nose and realizes operation, and whether stablizing of rotating shaft rotation also just determined the size of operating physical force and the stability of operation.The existing direct activity of rotary isolation switch spindle nose is matched with on the end carriage, is anchored on the spindle nose by stop block, prevents that spindle nose from doing axial motion, adjusts its gap by pad and back-up ring.As shown in Figure 1.Because the thickness of end carriage is too thin, make spindle nose and end carriage contact-making surface little, back-up ring and pad can only prevent the spindle nose axial motion, adjustable being limited in scope, can not eliminate its gap fully, when operation, because operating physical force has component in connecting lever rotation radial direction, cause spindle nose to occur swing easily, phenomenons such as operating physical force is big, on/off switch is not in place also just occurred, made the rotary isolation switch heating easily, electricity decreases big, directly influence the life-span of rotary isolation switch, can cause major accident when serious.
The utility model content
The purpose of this utility model is the rotary isolation switch spindle nose and the end carriage fit structure of a kind of rotating shaft good stability of design.
The utility model rotary isolation switch spindle nose and end carriage fit structure are that the end carriage at the rotary isolation switch underframe tightens an axle sleeve, and the spindle nose activity is matched with in the axle sleeve, can freely rotate in axle sleeve.
The rotary isolation switch spindle nose that the utility model provides has replaced spindle nose with the end carriage fit structure and has directly cooperated with end carriage, increased contact area, played guide effect, thereby strengthened the stability of whole rotating shaft, guaranteed the stability of rotating shaft spindle nose in rotary course, solved the spindle nose vibration problems that existing structure occurs in application process.Consumptive material is little, processing technology is simple.
Description of drawings
Fig. 1 is the structural representation of existing rotary isolation switch spindle nose and end carriage fit structure;
Fig. 2 is the structural representation of a utility model rotary isolation switch spindle nose and an embodiment of end carriage fit structure.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1, rise pin 2, connecting lever 3, back-up ring 4, stop block 5, end carriage 6, spindle nose 7, pad 8, axle sleeve
As shown in Figure 2, the utility model rotary isolation switch spindle nose and end carriage fit structure are to tighten intrinsic axle sleeve 8 at end carriage 5, and spindle nose 6 activities are matched with in the axle sleeve 8, can freely rotate in axle sleeve 8, stop block 4 secure fit are on spindle nose 6, and connecting lever 2 is by rising by pin 1 secure fit on spindle nose 6.
When operating physical force acts on the connecting lever 2, by rotation connecting lever 2 driven rotary spindle noses 6, because axle sleeve 8 secure fit are on end carriage 5, so the radial component of operating physical force on spindle nose 6 can not make spindle nose 6 swings, spindle nose 6 can only be done spinning movement, has strengthened the stability of whole rotating shaft.
Claims (1)
1, a kind of rotary isolation switch spindle nose and end carriage fit structure, comprise end carriage (5), spindle nose (6), be anchored on stop block (4) and connecting lever (2) on the spindle nose (6), it is characterized in that: end carriage (5) tightens intrinsic axle sleeve (8), spindle nose (6) activity is matched with in the axle sleeve (8), can freely rotate in axle sleeve (8).
