Abstract

An improved micro switch includes a switch body, a push switch, a contact spring and other components. The utility model is mainly characterized in that: the micro switch is connected with a positioning base and is provided with a rolling ball and a push rod in a container groove for the push link contact spring to touch the push switch; the utility model can make use of the flexible pivoting of the lower part of the rolling ball to make the utility model applicable for the push linkage of the linked body in any direction (universal), thus the utility model expands the use scope relatively and can further be flexibly applied in various machine tables, equipments or machineries more widely; in addition, as the micro switch makes use of the lower part of the equipped rolling ball for the push linkage, the utility model can not be limited by the fixed direction when in use, and also owing to the flexible and smooth pivoting of the rolling ball, the utility model can reduce damage rate relatively, so as to prolong the service life.

Description

Sensitive switch

Technical field

The utility model relates to a kind of improved sensitive switch, specifically, is meant a kind of improved spring-piece type sensitive switch.

Technical background

At present, spring-piece type sensitive switch 3 comprise members such as Switch main body 31, push switch 32 and contact flat spring 33, and wherein contact flat spring 33 has two pin-jointing pieces 331 usually with the wheel body 34 that is pivoted as shown in Figure 1.And the higher position 41 (as shown in Figure 2) of the link driving element 4 in wheel body 34 is rotated is when leaning, but interlock contact flat spring 33 upwards touches push switch 32.Yet board, equipment or machinery even same board, equipment or mechanical difference that the use through looking into sensitive switch 3 tends to according to different functions of use are used the position and may be had different fixed positions and direction.Lean travel direction when inconsistent when what the position that this sensitive switch 3 is fixed made wheel body 34 pivotal orientation of its contact flat spring 33 and aforementioned link driving element 4, as shown in Figure 3, if use this moment reluctantly, then the wheel body 34 that is pivoted of the contact flat spring 33 of this sensitive switch 3 is easy to and can produces skew, be out of shape even damage because of link driving element 4 undesired leans motion, and then cause the production of whole board, equipment or board or running to pause, and then keep in repair, thus, not only influence manufacturing schedule and efficient, also waste of manpower and man-hour.

Moreover, common schematic diagrames that use of

sensitive switch

51,52,53,54 as shown in Figure 4, two

sensitive switches

51,52 that wherein are positioned at the outside can be by the higher position of same moving part 6 forward (figure does not show) motion that leans, but it is inconsistent because of the direction of rotation of the pivotal orientation of its wheel body (figure does not show) and interlock effect 6 to be positioned at 53,54 of two inboard sensitive switches, therefore can not lean interlock by the higher position of moving part 6, even use reluctantly, not to cause that to damage be exactly to touch this

sensitive switch

53,54 at all.

Summary of the invention

The purpose of this utility model is to provide a kind of sensitive switch, the scope of application that can enlarge relatively, and then can apply in a flexible way in various boards, equipment more widely or mechanically.

For achieving the above object, sensitive switch of the present utility model comprises members such as Switch main body, push switch and contact flat spring, can be by contact flat spring by interlock and the roof pressure push switch, and this Switch main body is provided with location hole in addition in addition, it is characterized in that:

The location hole of the Switch main body of this sensitive switch is borrowed lock member or other to be connected and fixed mode to link a positioning seat, one side of this positioning seat has a storage tank, can supply a ccontaining ball and a push rod, and this push rod is positioned at the outer side-lower of described contact flat spring, the lower end suitable length of storage tank is then slightly stretched out in the below of described ball, by aforementioned feature, can utilize the below of ball to be leaned interlock and drive push rod roof pressure contact flat spring, make contact flat spring can touch push switch by the link driving element of all directions.

In addition, the storage tank of this positioning seat is a vertebra shape slotted eye, one lateral aperture of this vertebra shape slotted eye dwindles gradually to opposite side greatly, makes ball receive into this storage tank just, and makes ball neither can drop out the lower end suitable length that storage tank can stretch out storage tank again downwards downwards.

The utility model is by link a positioning seat on sensitive switch, and be pivoted ball and push rod touch push switch with roof pressure interlock contact flat spring, can be applicable to the roof pressure interlock of the interlock body of either direction by means of flexible pivot the in ball below, can enlarge the scope of application relatively, and then apply in a flexible way in various boards, equipment more widely or mechanically, and sensitive switch borrows its ball that is pivoted below by the roof pressure interlock, be not subjected to the restriction of fixed-direction when therefore not only using, more pivot flexibly with smoothly because of ball, can reduce its spoilage relatively, and then improve useful life.

Embodiment

Shown in Fig. 5～6, the utility model is a kind of improved sensitive switch, it is a kind of spring-piece type sensitive switch, this sensitive switch 1 comprises members such as Switch main body 11, push switch 12 and contact flat spring 13, can be by contact flat spring 13 by interlock and roof pressure push switch 12, this Switch main body 11 is provided with location hole 111,112 in addition in addition, it is characterized in that:

Shown in Fig. 7～8, the location hole 111 of this sensitive switch 1 Switch main body 11 is borrowed lock member 10 or other to be connected and fixed mode to link a positioning seat 2, one side of this positioning seat 2 has a storage tank 21, can supply a ccontaining ball 22 and a push rod 23, and make push rod 23 be positioned at the outer side-lower of described contact flat spring 13 just, and aforesaid ball 22 belows 221 can be leaned interlock and drive push rod 23 roof pressure contact flat springs 13 by the link driving element of all directions (everything) (figure does not show), make contact flat spring 13 can touch push switch 12 (Fig. 8).

Secondly, the storage tank 21 of aforementioned positioning seat 2 is a vertebra shape slotted eye, and a lateral aperture of this vertebra shape slotted eye dwindles gradually to opposite side greatly, makes ball 22 receive into this storage tank 21 just, make ball 22 neither can drop out storage tank 21 downwards, can stretch out storage tank 21 lower ends 211 suitable lengths again downwards.

In addition, a side of this positioning seat 2 is provided with location hole 24,25 in addition, can borrow lock member (figure does not show) and suitable position locking to link in addition.

In sum, the utility model can be concluded and be had following enhancement effect:

1, links a positioning seat 2 by sensitive switch 1, and the ball 22 that is pivoted touches push switch 12 with push rod 23 for roof pressure interlock contact flat spring 13, can borrow ball 22 belows the flexible roof pressure interlock that pivots and be applicable to either direction interlock body (scheming not show), relatively enlarge the scope of application, and then can apply in a flexible way in various boards, equipment more widely or mechanically.

2, sensitive switch 1 borrows the below 221 of its ball that is pivoted 22 by the roof pressure interlock, be not subjected to the restriction of fixed-direction when therefore not only using, more pivot flexibly with smoothly because of ball 22, can reduce its spoilage relatively, and then improve useful life, and avoid influencing the generation of the situation of manufacturing schedule because of sensitive switch 1 fault causes production operation to pause.
