Specific embodiment
Be described further below technical solution of the present invention, but claimed range be not limited to it is described.
A kind of drawing combination button switch with precompressed stroke novel locking mechanism as shown in Figures 1 to 5, including drawing
Mechanism, locking mechanism, precompressed Strok mechanism and contact mechanism；In drawing mechanism lower inside position, from top to bottom successively
Fixation locking mechanism, precompressed Strok mechanism and contact mechanism；The locking mechanism includes positioning sleeve 21 and steel ball 22, positioning sleeve 21
On have two groups of symmetrically arranged lock slots up and down, the upper locking groove position corresponded on positioning sleeve 21 in the handle 4 of drawing mechanism has
Groove, steel ball 22 are placed in the lower lock slots on positioning sleeve 21 and can be limited by the groove on handle 4 and via the shifting of handle 4
It moves and is taken in the upper locking groove on steel ball 22.
The drawing mechanism is made of handle cap 1, compression spring 2, handle 4, pull rod 5, shell 6, middle pressure spring 23, the handle cap 1
It covers on the top of handle 4,5 sets of the pull rod middle parts in handle 4, is connected and fixed compression spring 2 between handle cap 1 and pull rod 5,6 sets of shell
In pull rod 5, steel ball 22 is fixed on 5 lower end of pull rod, and there is outwardly extending step structure at the middle part of pull rod 5, and middle 23 lower end of pressure spring is solid
It is scheduled on the step structure of pull rod 5, the top edge inner bottom surface of shell 6 is fixed in middle 23 upper end of pressure spring.
The precompressed Strok mechanism is made of briquetting 31, pressing ring 32, lower pressure spring 33, push rod 34, and 34 sets of push rod in handle 4
In the inner hole of bottom end, the fixed briquetting 31 in 34 lower end of push rod, 33 sets of lower pressure spring is on push rod 34 and handle is fixed in 33 upper end of lower pressure spring
4, briquetting 31 is fixed in lower end, and pressing ring 32 is pressed on briquetting 31.
The contact mechanism is made of microswitch 41, pedestal 42, positioning pin 43, and microswitch 41 is in electrical contact with briquetting
31, it is outer that microswitch 41 is fixed that pedestal 42 is wrapped in microswitch 41, and pedestal 42 is fixed on the lower end of shell 6, positioning pin
43 are fixed on microswitch 41 in pedestal 42.
Also suit is fixed with nut 7 on the shell 6.
There is drawing shell 3 in the outside of the shell 6, and the lower end of drawing shell 3 is located at the middle part of shell 6, upper end and is located at handle
The middle part of cap 1, so that shell 6 and handle cap 1 are relatively fixed.
Pressing ring 32 is fixed in the lower end of the pull rod 5.
Pedestal 42 is fixed in the lower end of the positioning sleeve 21.
The present invention can assemble in accordance with the following steps:
1, pull rod 5 is turned over together with riveting with pressing ring 32, is reloaded into 2 steel balls 22, is assembled into component 51；
2, handle 4 and push rod 34 are detained together with riveting, is reloaded into components A, puts on positioning sleeve 21,33 sets of lower pressure spring is existed
On push rod 34, refills upper holder block 31 and turn over and rivet tightly, be assembled into precompressed Strok mechanism 3；
3,2 microswitches 41 are fitted into pedestal 42, and are coupled to together with 2 positioning pins 43, be assembled into and connect
It has a sudden inspiration structure 4；
4,23 sets of middle pressure spring are reloaded into shell 6 on the pull rod 5 in precompressed Strok mechanism 3, then load onto contact machine
Structure 4, and by shell 6 together with the button riveting of pedestal 42 in contact mechanism 4；
5, screw thread glue is coated respectively outside the screw thread of the pull rod 5 in drawing mechanism 1 and at the screw thread of handle 4, then put on
Then pressure spring 2 is inserted in 1 precession handle 4 of handle cap in drawing shell 3 together and screws；
6, finally nut 7 is screwed in shell 6, point epoxide-resin glue sealing at riveting is turned in pedestal 42 and shell 6, in room
Temperature is lower to be stood for 24 hours.
Working principle about steel ball 22 is:
Under original state, two steel balls 22 are stuck in the lower lock slots of positioning sleeve 21, and each conductive feet of switch, which is in, to be disconnected
State presses downwards handle 4, is displaced downwardly to the groove of handle 4 at 22 position of steel ball, and switch unlock pulls drawing shell at this time
3, drive pull rod 5, handle 4 and steel ball 22 to move upwardly together, a, b conductive feet of switch are connected, and c, d conductive feet are connected, and work as fortune
It moves removal pressing force, handle 4 at the upper locking groove of positioning sleeve 21 to move upwards under the rebound effect of compression spring 2, at this time
Groove and steel ball 22 on handle 4 misplace, and the non-recessed portion of handle 4 forces steel ball 22 into the upper locking groove of positioning sleeve 21
In, switch is locked again；It presses handle 4 downwards again, is displaced downwardly to the groove of handle 4 at 22 position of steel ball, switch solves again
Lock, under the rebound effect of middle pressure spring 23, switch returns to original state, removes pressing force, rebound of the handle 4 in compression spring 2
Return, switch realize that original state is self-locking again under power effect, and entire circuit is in an off state, and switch is completed one-off and followed
Ring.
The operating principle of precompressed Strok mechanism is:
When not operating, lower pressure spring 33 is in highly compressed state, and 34 upper end of push rod is in the inner hole upper surface of handle 4, with
The briquetting 31 that 34 lower end of push rod is coupled tightly touch microswitch 41 under the pressure of lower pressure spring 33, and switching circuit is constantly in
Northern state is disconnected, when pulling up to 3mm, push rod 34 has moved to the lower end of 4 inner hole of handle, and precompressed stroke is finished at this time,
Microswitch 41 commutates, and a, b foot of switch are connected, and c, d foot are connected.The setting value of pretravel be 3mm, can effectively prevent switch because
The possibility of malfunction is accidentally hit and generated, ensure that the high reliability of switch.
As it can be seen that in the present invention:
1, lock function key by handle cap 1, compression spring 2, drawing shell 3, handle 4, pull rod 5, positioning sleeve 21, steel ball 22,
The middle joint of pressure spring 23 is realized.Handle 4 is pressed when work, is displaced downwardly to the groove of handle 4 at 22 position of steel ball, switch unlock, this
Shi Ladong drawing shell 3 drives pull rod 5, handle 4 and steel ball 22 to move upwardly together, when the upper positioning for moving to positioning sleeve 21
Pressing force is removed at slot, handle 4 moves upwards under the rebound effect of pressure spring 2, and the groove on handle 4 and steel ball 22 are wrong at this time
Position, the non-recessed portion of handle 4 force steel ball 22 to enter in the upper locating slot of positioning sleeve 21, and switch is locked again.With existing skill
Art compares, which has the characteristics that terse, the highly reliable locking of design, extra long life.
2, precompressed Strok mechanism can effectively increase the precompressed stroke of switch, and the contact mechanism of switch can not only be made to realize
Self-control, moreover it is possible to effectively prevent external strength accidentally to rush open and close and switch is made to generate the possibility of malfunction, ensure that switch motion
Reliability.
