Description
Technical field
The utility model is related to High-Voltage Electrical Appliances accessories technical fields, and in particular to it is a kind of can low-angle adjust auxiliary switch
Linkage structure.
Background technology
Auxiliary switch is configured in high-voltage breaker operation mechanism, is grasped auxiliary switch rotary shaft and breaker using connecting lever
Motivation structure connects, and by changing the on off operating mode of own node, separating brake, combined floodgate shape are indicated in high-voltage circuitbreaker secondary circuit
State plays the role of signal control and interlock protection.
Existing auxiliary switch rotary shaft is generally long cube, and connecting lever is rectangular with rotation shaft connection place section, causes it
It can only be one kind in 90 °, 180 °, 270 ° to adjust angle.In day-to-day operation, breaker mechanism is adjusted or abrasion deformation
Afterwards, since rotation distance changes, cause auxiliary switch that cannot switch in place, need to connect auxiliary switch connecting lever and rotary shaft
It connects angle to be adjusted, adjusts the angle in this case smaller, and under existing auxiliary switch linkage structure, adjusting angle can only be with
90 ° are least unit, it is difficult to achieve the purpose that fine tuning, great inconvenience is brought to overhaul of the equipments work.
In consideration of it, it is necessary to be improved existing auxiliary switch linkage structure.
Utility model content
(1) technical problems to be solved
In order to overcome the shortage of prior art, it is proposed that it is a kind of can low-angle adjust auxiliary switch linkage structure, structure
Simply, the relative position that connecting lever and rotary shaft can be adjusted with low-angle, to achieve the purpose that change rotary shaft rotational angle.
(2) technical solution
The utility model is achieved through the following technical solutions：The utility model proposes it is a kind of can low-angle adjust auxiliary
Switch gearing structure, including auxiliary switch ontology and the connecting lever that is connected in high-voltage circuit-breaker operating mechanism, the auxiliary are opened
It closes and is provided with a rotary shaft free to rotate in ontology and the outboard end of rotary shaft is provided with spline, the middle part of the connecting lever
It is provided with a splined hole, the top of connecting lever is provided with a clearance groove for extending to splined hole, and the both sides of clearance groove are respectively arranged with
One is located at threaded hole and through-hole on connecting lever, and end and the threaded hole screw thread of a bolt and the bolt are equipped in the through-hole
Connection, the rotary shaft carry out spline with the splined hole on connecting lever by spline and couple.
Further, the spline and splined hole include 36 spline tooths.
(3) advantageous effect
The utility model compared with the existing technology, has the advantages that：
The utility model mention it is a kind of can low-angle adjust auxiliary switch linkage structure, will be in prior art products
Connecting lever is changed to spline with the rotary shaft connection on auxiliary switch and couples, itself and auxiliary are realized by can arbitrarily rotate connecting lever
The connection of rotary shaft on switch, may be implemented the adjusting of low-angle, and specific angular adjustment can be according to spline and splined hole
Tooth position variation is adjusted, and can improve auxiliary switch sensitivity.

Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
It is as shown in Figure 1 it is a kind of can the auxiliary switch linkage structure that adjusts of low-angle, including auxiliary switch ontology 1 and connection
The connecting lever 2 being connected in high-voltage circuit-breaker operating mechanism is provided with a rotary shaft free to rotate in the auxiliary switch ontology 1
3 and the outboard end of rotary shaft 3 is provided with spline 4, the middle part of the connecting lever 2 is provided with a splined hole 5, and the top of connecting lever 2 is set
Be equipped with a clearance groove 6 for extending to splined hole 5, the both sides of clearance groove 6 be respectively arranged with the threaded hole 7 that one is located on connecting lever 2 with
And through-hole 8, a bolt 9 is equipped in the through-hole 8 and the end of the bolt 9 is threadedly coupled with threaded hole 7, the rotary shaft 3
Spline is carried out by spline 4 with the splined hole 5 on connecting lever 2 to couple.
Wherein, the spline 4 and splined hole 5 include 36 spline tooths.
The utility model mention it is a kind of can low-angle adjust auxiliary switch linkage structure turned when specifically used
Arm 2 is open by the fork-shaped of its end and is connect with high-voltage circuit-breaker operating mechanism, when breaker mechanism is adjusted or wears change
After shape, bolt 9 is unscrewed first, connecting lever 2 is taken out from rotary shaft 3, the angle required according to on-site actual situations is adjusted
3 angle of rotary shaft, rotary shaft 3 are inserted into auxiliary switch ontology 1 and drive internal node to carry out point, close conversion, and connecting lever 2 is passed through spline
Hole 5 is nested on the spline 4 in rotary shaft 3, is then fastened bolt 9 using tool, to reach consolidating for connecting lever 2 and rotary shaft 3
Fixed purpose is completed rotation shaft angle and is adjusted, is worth mentioning, 36 spline tooths are provided on spline 4 and splined hole 5,
A tooth position variation is often rotated, 3 rotational angle of rotary shaft is 10 ° at this time.
Embodiment described above is only that preferred embodiments of the present invention are described, not to this practicality
Novel conception and scope is defined.Without departing from the design concept of the present utility model, ordinary people in the field couple
The all variations and modifications that the technical solution of the utility model is made, should fall within the protection scope of the present utility model, this reality
With novel claimed technology contents, all record in detail in the claims.
