[0001] The present invention relates to a rotary switch, and in
particular, to an operating mechanism for rotary switch.
[0002] The rotary switch is isolating switch. When at switching
off position, the insulation distance between the moving and
static contact shall meet the specified requirements, and the
switch shall have an obvious disconnection mark. When at the
switching-on position, the contact shall be capable of carrying
the current under normal circuit conditions or the current under
abnormal conditions within a specified time. When the
electrician is required operated, they need to cut off the power
and padlock when necessary to prevent accidental operation by
others and to ensure the safety of operator. However, Under the
condition that the moving and static contact are melted welding,
the power may fail to be cut off only by the rotary switch. If
the moving and static contact fail to work to cut off the
current while the twist grip shows switching-off or even show
padlocked, the operator may continue the operation for they
think the current has been successfully cut off, which makes the
electric shock extremely easily occur. The national standard on
the operating mechanism for rotary switch requires that: when
the contacts are melted and welded when at switching-on
position, the operating force for rotating the switch handle to
switching-off should be at least triple the operating force (and no less than 100N) under normal conditions. Existing operating mechanism satisfies the standard through a design with torsional spring. The operator may be aware of the abnormal situation through feeling different operating force. However, this is not entirely reliable. Failure to feel the different operating force due to unfamiliar operation or operator's being more of strength results in the potential hazards.
[0003] The present invention aims at overcoming the defects of
existing technology and providing an operating mechanism for
rotary switch.
[0004] The technical proposal adopted by the present invention
is as follows: an operating mechanism for rotary switch
comprises a mounting base; an operating rod assembly used for
manual rotation and a turntable assembly are arranged in the
claimed mounting base; an energy storage element is arranged
between the claimed operating rod assembly and turntable
assembly. The turntable assembly realizes switching-on or
switching-off of the switch through forward rotation or reverse
rotation. The operating rod assembly rotates to enable the
energy storage element to drive the turntable assembly to
rotate. A stop block is hinged into the mounting base and
comprises a promotion part and a blocking part. The turntable
assembly and the promotion part work together so that the stop
block can rotate to the first position and the second position
relative to the mounting base: when the turntable assembly is
located at the switching-on position, the turntable assembly
reaches the promotion part so that the stop block is at the first position , and thereby the blocking part is located on the rotating path of the operating rod assembly or the energy storage element to block and limit the rotation of the operating rod assembly. When the turntable assembly is located at the switching-off position, the turntable assembly is separated from the promotion part, the stop block is located at the second position, the blocking and limiting effect on the rotation of the operating rod assembly from the blocking part is removed.
[0005] A first reset elastic piece is arranged on the claimed
stop block to make the stop block locate at the second position.
[0006] A first spring limit post is affixed on the promotion
part of the claimed stop block. The claimed first reset elastic
piece is a pressure spring held by the first spring limit post.
The claimed mounting base is disposed by a spring limit slot.
[0007] A first smooth surface is designed at the side wall of
the claimed promotion part matching the turntable assembly.
[0008] The claimed operating rod assembly comprises an operating
rod and a cam arranged around the operating rod and in the
circumferential direction linked with the claimed operating rod;
the claimed turntable assembly comprises a turntable and a
sliding block set on the turntable and slides radially relative
to the claimed turntable; in the claimed mounting base two
sliding block slots are arranged corresponding to the switching
on and switching-off positions of the turntable assembly; a
second reset elastic piece which can make the sliding block
insert into the sliding block slot is arranged between the
claimed turntable and the sliding block; when the claimed sliding block inserts into the slot, the claimed turntable assembly is not rotatable and when the claimed sliding block leaves the slot, the claimed turntable assembly is rotatable; the claimed sliding block is arranged under the cam and there is a push plate arranged for the claimed cam. The claimed cam rotates so that the push plate removes the sliding block from the sliding block slot.
[0009] The claimed turntable raises up with a side plate, and a
second spring limit post is designed in the inner side of the
claimed side plate; the push plate is provided with a first
through hole through which the second spring limit post passes
and matches. The claimed second reset elastic piece is a
pressure spring and is sleeved on the second spring limit post.
The two ends of the second reset elastic piece respectively abut
against the side plate and the push plate.
[0010] The claimed mounting base is equipped with a first limit
baffle and a second limit baffle matching the claimed side
plate, the claimed side plate rotates between the first limit
baffle and the second limit baffle.
[0011] The claimed energy storage element is a disk torsional
spring with two flexible manipulators, the claimed cam upwardly
convex with a first spring roof, the claimed sliding block
upwardly convex with a second spring roof, the first spring roof
and the second spring roof are of the same width, the two
flexible manipulators rely on the first spring roof and the
second spring roof on their two sides respectively.
[0012] The claimed turntable is provided with a square bump, and the claimed sliding block is provided with a square sliding groove matching with the sliding of the square bump.
[0013] The square bump is provided with a circular through hole,
and the bottom of the operating rod inserts into a circular
through the hole.
[0014] The advantageous effect of the present invention is as
follows: under normal circumstance, the operating rod assembly
links to the handle and the switching-on or switching-off can be
realized through the rotation of the turntable assembly driven
by the energy storage element after rotating the handle. Under
the condition that a contact is melted welding, the turntable
assembly is kept at the switching-on position and cannot rotate.
The turntable assembly abuts against the promotion part. The
operating rod assembly is prevented from rotating to the
switching-off position through the blocking part. And what the
rotating handle shows is not switching-off. If applied to the
switch with switching-off padlock, the padlock fails to work.
Therefore, an operator can easily find the melted welding
condition and then further carry out the safety operation. The
potential safety hazards are reduced.

invention or the existing technical proposal, a brief
introduction of drawings demanded by the examples or the

[0017] To clearly specify the purpose, the technical proposal
and the advantages of the present invention, the present
invention shall be further particularly described as follows.
[0018] What needs illustration is that all the description
involving "first" and "second" aims at distinguish the two
different entities by the same name or two different parameters
by the same name. Such description is only for convenience and
it should not be deemed as the limitation to the invention
examples. No further explanation shall be made hereafter.
[0019] All terms used for describing the direction or the
position herein, such as "up", "down", "front", "back", "left",
"right", "internal", "external", "top", "bottom" and "side",
etc., are used comparatively to the direction or position of the
figure. Therefore, these terms are only used for illustration
and comprehension of the present invention and shall not be
deemed as the limitation on the scope of protection thereto.
[0020] As shown in Figure 1 to Figure 3, the operating mechanism
for rotary switch comprises a mounting base 1; a operating rod
assembly used for manual rotation 2 and a turntable assembly 3
are arranged in the claimed mounting base 1; an energy storage
element 4 is arranged between the claimed operating rod assembly
2 and turntable assembly 3. The turntable assembly 3 realizes
switching-on or switching-off of the switch through forward
rotation or reverse rotation. The operating rod assembly 2
rotates to enable the energy storage element 4 to drive the
turntable assembly 3 to rotate. A stop block 5 is hinged into
the mounting base 1 and comprises a promotion part 501 and a
blocking part 502. The turntable assembly 3 and the promotion
part 501 work together so that the stop block 5 can rotate to
the first position and the second position relative to the
mounting base 1: when the turntable assembly 3 is located at the
switching-on position, the turntable assembly 3 reaches the
promotion part 501 so that the stop block 5 is at the first
position and thereby the blocking part 502 is located on the
rotating path of the operating rod assembly 2 or the energy
storage element 4 to block and limit the rotation of the
operating rod assembly 2. When the turntable assembly 3 is
located at the switching-off position, the turntable assembly 3
is separated from the promotion part 501, the stop block 5 is
located at the second position, the blocking and limiting effect
on the rotation of the operating rod assembly 2 from the
blocking part 502 is removed. Under normal circumstance, the
operating rod assembly links to the handle and the switching-on
or switching-off can be realized through the rotation of the
turntable assembly driven by the energy storage element after
rotating the hand shank. Under the condition that a contact is
melted and welded, the turntable assembly is kept at the
switching-on position and cannot rotate. The turntable assembly
abuts against the promotion part. The operating rod assembly is
prevented from rotating to the switching-off position through
the blocking part. And what the rotating handle shows is not
switching-off. If applied to the switch with switching-off padlock, the padlock fails to work. Therefore, an operator can easily find the melted and welded condition and then further carry out the safety operation. The potential safety hazards are reduced.
[0021] The first reset elastic piece 503 is arranged on the
claimed stop block 5 to make the stop block 5 locate at the
second position.
[0022] The first spring limit post 504 is affixed on the
promotion part 501 of the claimed stop block 5. The claimed
first reset elastic piece 503 is a pressure spring held by the
first spring limit post 504. The claimed mounting base 1 is
equipped with a spring limit slot 101. Driving to reset can be
realized by arranging a torsional spring around the hinging
post.
[0023] The first smooth surface 501 is designed at the side wall
of the claimed promotion part 501 matching the turntable
assembly 3.
[0024] In Figure 2, the turntable assembly 3 and the operating
rod assembly 2 are both in switching-on position and stop block
locates at the first position. As shown in Figure 2, when the
turntable assembly 3 anticlockwise rotates, the stop block 5
will anticlockwise rotates around the hinging post pushed by the
first reset elastic piece 503. When the stop block 5 rotates to
the second position, the blocking and limitation on the rotation
of the operating rod assembly 2 by the claimed blocking part 502
shall be removed. When the turntable assembly 3 rotates
clockwise to original position, the promotion part 501 is driven by the turntable assembly 3 to make the stop block 5 clockwise rotate around the hinging post and thereby the stop block 5 gets back to the first position. The blocking part 502 locates on the rotating path of the energy storage element 4 and its function is to prevent the continuing rotation of the energy storage element 4 and the operating rod assembly 2. The first smooth surface 505 reduces the friction and contributes to pushing. The energy storage element 4 has two flexible manipulators 401. When the stop block 5 locates at the first position, the blocking part 502 locates at the rotating path of the flexible manipulator 401 in the right side as shown in Figure 4. A limiting bump may be arranged on the operating rod assembly 2 to match the stop block 5.
[0025] As shown in Figure 4, the claimed operating rod assembly
2 comprises an operating rod 201 and a cam 202 arranged around
the operating rod 201 and in the circumferential direction
linked with the claimed operating rod 201; the claimed turntable
assembly 3 comprises a turntable 301 and a sliding block 302 set
on the turntable 301 and slides radially relative to the claimed
turntable 301; on the claimed mounting base 1 two sliding block
slots 102 are arranged corresponding to the switching-on and
switching-off positions of the turntable assembly 3; the second
reset elastic piece 303 which can make the sliding block 302
insert into the sliding block slot 102 is arranged between the
claimed turntable 301 and the sliding block 302; when the
claimed sliding block 301 inserts into the slot 102, the claimed
turntable assembly 3 is not rotatable and when the claimed
sliding block 302 leaves the slot 102, the claimed turntable
assembly 3 is rotatable; the claimed sliding block 302 is
arranged under the cam 202 and there is an push plate 3011 arranged for the claimed cam 202. The claimed cam 202 turns the push plate 3011 to remove the sliding block from the sliding block slot 102. The arrangement of the cam and the sliding block help to limitation of the position of the turntable assembly 3 when rotating to switching-on or switching-off status and to keep such status.
[0026] The claimed turntable 301 has raised by the side plate
304, and the side plate 304 has the second spring limit post
305, the push plate 3011 is disposed by the first through hole
306 through which the second spring limit post 305 passes and
matches. The claimed second reset elastic piece 303 is a
pressure spring and is sleeved on the second spring limit post
305. The two ends of the second reset elastic piece 303
respectively abut against the side plate 304 and the push plate
3011.
[0027] The claimed mounting base 1 is equipped with a first
limit baffle 103 and a second limit baffle 104 matching the
claimed side plate 304, the claimed side plate 304 rotates
between the first limit baffle 103 and the second limit baffle
104.
[0028] The claimed energy storage element 4 is a disk torsional
spring with two flexible manipulators 401, the claimed cam 202
raising up with the first spring roof 203, the claimed sliding
block 302 raising up with the second spring roof 307, the first
spring roof 203 and the second spring roof 307 are of the same
width, the two flexible manipulators 401 rely on the first
spring roof 203 and the second spring roof 307 on their two
sides respectively.
[0029] The Figure shows a switching-on status. When needs to
switch on, the operating rod 201 and the cam 202 anticlockwise
rotates. The cam 202 pushes the flexible manipulator 401 at the
right side shown in Figure 4 to the switching-on position. The
projecting part of the cam 202 promotes the push plate 3011 and
the sliding block 302 leaves the sliding block slot 102. At this
moment, the turntable assembly 3 is rotatable in the mounting
base 1. The flexible manipulator 401 at the left side rotates
with the turntable assembly 3 to the switching-on position. When
needs to switch off, the cam 202 pushes the flexible manipulator
401 at the left side as shown in Figure 4 to the switching-off
position. At the same time, the push plate 3011 is driven and
the sliding block 302 leaves the other sliding block slot 102.
The flexible manipulator 401 at the right side rotates with the
turntable assembly 3 to the switching-off position.
[0030] When the contact is melted and welded, the turntable
assembly 3 is not rotatable. When needs to switch off, the
operating rod assembly 2 can only rotate to the position of the
blocking part 502 and no more rotation can be made. At this
time, loose the operating handle, the energy storage element 4
will rotate back to the original position together with the
operating rod assembly 2.
[0031] The claimed turntable 301 is provided with a square bump
308, and the claimed sliding block 302 is provided with a square
sliding groove 309 matching with the sliding of the square bump
308.
[0032] The claimed the square bump 308 is disposed by a circular
through hole 3010, and the operating rod 201 inserts into the circular through hole 3010 from the bottom end so that the operating rod 201 can be fixed.
[0033] As illustrated by Figure 6(b), when the sliding block
leaves the groove, it meets the external circle of the turntable
to compose a cylinder. Side plate 304 arranged on the turntable
has a fan-shaped hump. The fan-shaped hump, together with the
first limit baffle 103 and the second limit baffle 104, set a
limitation on the rotation angle. At the same time, the fan
shaped hump matches the promotion part 501.
[0034] All the disclosures above are some better examples of the
present invention, by which the scope of claims of the present
invention shall not be limited. Thus, some equivalent change
made according to the claims of the present invention shall
belong to the scope of the present invention.
