Description
Technical field
A kind of earthed switch field of high-tension switch gear is the utility model is related to, is grasped more particularly to a kind of earthed switch
Make box screw handle device.
Background technology
Existing earthed switch operating case screw handle is to be assembled together by cast aluminium screw rod and handle by bearing pin, so
Afterwards on earthed switch operating case with split washer card on the positioning element, prevent screw handle from moving forward and backward, the assembling of this device
Complexity, low production efficiency, labour cost and material cost are high.
The content of the invention
The purpose of this utility model is to provide the earthed switch operating case screw rod that a kind of assembling is easy, service life is longer
Handle apparatus.
To achieve the above object, technical solution of the present utility model is：
The utility model is a kind of earthed switch operating case screw handle device, including operating case shell, screw handle, fixed
Position part, screw mandrel axle sleeve, nut；Described screw handle includes screw body, boss, T-shaped thread, step-shaped top position, head thread, hand
Handle inner hexagonal hole, one end of described screw body is provided with head thread, adjacent with head thread to be sequentially provided with step-shaped top position, boss
With T-shaped thread, handle inner hexagonal hole is opened up in the other end of screw body；Described keeper is fixedly mounted in operating case shell
On wall, gap passes positioning hole on keeper from inside to outside for the head thread of screw handle, and the boss of screw handle acts against
On keeper, screw mandrel axle sleeve is socketed in the head screw tooth end of screw handle and leaned with step-shaped top position, operating case shell and screw mandrel
There is gap, nut is screwed onto the head screw tooth end of screw handle and leaned with the outer end of screw mandrel axle sleeve between axle sleeve.
Described nut has two, and two nuts are all screwed onto the head screw tooth end of screw handle and between two nuts
Provided with elastomeric pad.
After such scheme, because the utility model including screw handle is provided with boss and step-shaped top position, screw handle
Head thread activity place in positioning hole on the positioning element, the boss of screw handle leans on the positioning element, screw mandrel axle sleeve
It is socketed in the head screw tooth end of screw handle and is leaned with step-shaped top position, there is gap between operating case shell and screw mandrel axle sleeve,
Lubricating oil is applied in gap so that when rotating, screw mandrel axle sleeve will not produce serious fretting wear with shell and become screw handle
Shape, there is the advantages of assembling is easy, service life is longer, production cost is relatively low, screw handle rotation is more laborsaving.
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings.
Brief description of the drawings
Fig. 1 is axonometric drawing of the present utility model；
Fig. 2 is front view of the present utility model；
Fig. 3 is the front view of the utility model screw handle.
Embodiment
As shown in Figure 1-Figure 3, the utility model is a kind of earthed switch operating case screw handle device, including outside operating case
Shell 1, screw handle 2, keeper 3, screw mandrel axle sleeve 4, two nuts 5, elastomeric pads 6.
Described screw handle 2 includes screw body 21, boss 22, T-shaped thread 23, step-shaped top position 24, head thread 25, hand
Handle inner hexagonal hole 26.One end of described screw body 21 is provided with head thread 25, adjacent with head thread 25 to be sequentially provided with step
Position 24, boss 22 and T-shaped thread 23 are pushed up, handle inner hexagonal hole 26 is opened up in the other end of screw body 21.
Described keeper 3 adds elastomeric pad 23 to rivet together to be fixedly mounted on the inwall of operating case shell 1 by rivet
On.From inside to outside, gap passes positioning hole on keeper 3 to the head thread 25 of screw handle 2, and the boss 22 of screw handle 2 pushes up
Lean against on keeper 3, prevent screw handle 2 from being moved forward because of stress；Screw mandrel axle sleeve 4 is socketed in the head thread of screw handle 2
25 ends and leaned with step-shaped top position 24, there is 1m gap, two nuts 5 are all between operating case shell 1 and screw mandrel axle sleeve 4
It is screwed onto the end of head thread 25 of screw handle 2 and mutually to lock, elastomeric pad 6, the spiral shell of inner side is provided between two nuts 5
Mother 5 and the outer end of screw mandrel axle sleeve 4 lean.
Assembly method of the present utility model：
1. installation of the screw handle 2 on earthed switch operating case shell 1, the head thread 25 of screw handle 2, which passes through, to be determined
After position part 3 is rotatably arranged on operating case shell 1, screw mandrel axle sleeve 4 is inserted in, is then locked with two M16 nuts 5, and cover
Enter φ 16 elastomeric pad 6 and M16 nuts 5, two nuts 5 are mutually relative to be locked, after screw mandrel axle sleeve 4 is inserted in the head of screw handle 2
Held out against with the step-shaped top position 24 of screw handle 2, make to produce one 1 millimeter of gap between operating case shell 1 and screw mandrel axle sleeve 4,
Lubricating oil is applied in gap, when preventing that screw handle from rotating, screw mandrel axle sleeve 4 seriously becomes part with the fretting wear of operating case shell 1
Shape, with nut 5 plus the locking screw axle sleeve 4 of elastomeric pad 6, prevent that screw mandrel axle sleeve 4 from sliding and screw handle 2 drops out backward.
2. then branch code 10 to be inserted in the position of handle 27 of screw handle 2, it is locked in corresponding to operating case shell 1 in hole position,
Branch code 10 is to add cone pad and nut to be locked in together on operating case shell 1 with screw.
3. the handle inner hexagonal hole 26 of the afterbody of screw handle 2 is for inserting rocking handle, driving screw handle 2 to rotate.
It is described above, only the utility model preferred embodiment, therefore the utility model implementation can not be limited with this
Scope, i.e., the equivalent changes and modifications made according to present utility model application the scope of the claims and description, it all should still belong to this reality
In the range of being covered with new patent.
