Description

The multisection type switch

The utility model relates to push switch.

Existing machinery formula push switch is limited to its structure, mostly can only do two sections of open and close or three sections kinds switchings, selects if desire cooperates multisection type to switch, and then can't use at this point; And another kind of electronic switch, though can make the multisection type diverter switch, it is high that its precision part requires, not anti-collision and cost costliness, and the switch that especially applies to waterproof or guide and support portable product uses, and easilier causes malfunctioning fault, brings inconvenience to the user.

The purpose of this utility model provides a kind of anti-collision, not easy to failure and have a multisection type switch that multistage switches.

The purpose of this utility model is achieved in that the multisection type switch, it comprises pedestal, barrel button, turn cylinder, compression spring, cylindricality ring guide card, returning spring, conducting strip group and holder, it is characterized in that: both sides are provided with barb wall and the adjacent awl post of spacing on the pedestal pedestal wall edge, each adjacent awl intercolumniation is laid the pin rod for conducting strip group difference intercalation location, the pedestal internal ring wall is arranged with vertical fin, and each fin upper limb is a bevelling; Barrel button upper limb wall forms serration, and sidewall is prominent establishes the arrangement fin, and acies is identical with the serration shape on this fin; The turn cylinder is a large and small class body, and little class body lower edge ring wall forms the serration that is meshed with the serration of barrel button, and the turn column side wall is provided with vertical fin, and this fin lower edge has a bevelling, the positioning pin column that prolongs on top end wall has; In the ccontaining turn cylinder of compression spring; Cylindricality ring guide card cylinder is placed in the turn cylinder, and guide card is provided with relative breach and lug, and the breach cover is due to positioning pin column; Returning spring is placed in the cylindricality ring guide card and with a holder basing; The conducting strip group is Y type guide card by one and the rectangle guide card is formed; Holder adapts to base shape and is combined as a whole.

Above-mentioned design, combination back test is used, and has reached anti-collision, effect not easy to failure.

Below by drawings and Examples the utility model is described further again.

Shown in Fig. 1-2: the utility model comprises pedestal 1, barrel button 2, turn cylinder 3, compression spring 4, cylindricality ring guide card 5, returning spring 6, conducting strip group 7 and holder 8, it is characterized in that: both sides are provided with barb wall 12 and the adjacent awl post 13 of spacing on the pedestal 1 pedestal wall edge, 13 layings of each adjacent awl post are for the pin rod 14 of conducting strip group 7 difference intercalation location, pedestal 1 internal ring wall is arranged with vertical fin 15, and each fin 15 upper limb is a bevelling 151; Barrel button 2 upper limb walls form serration 21, and prominent the establishing of sidewall arranged fin 22, and acies is identical with serration 21 shapes on this fin 22; Turn cylinder 3 is a large and small class body, little class body lower edge ring wall forms the serration 31 that is meshed with the serration 21 of barrel button 2, the turn column side wall is provided with vertical fin 32, and these fin 32 lower edges have a bevelling 321, the positioning pin column 33 that prolongs on top end wall has; In the compression spring 4 ccontaining turn cylinders 3; Cylindricality ring guide card 5 cylinders 51 are placed in turn cylinder 3, and guide card 52 is provided with relative breach 521 and lug 522, and breach 522 covers are due to positioning pin column 33; Returning spring 6 is placed in the cylindricality ring guide card 5 and with a holder 8 basings 1; Conducting strip group 7 is Y type guide card 71 by one and rectangle guide card 72 is formed; Holder 8 adapts to pedestal 1 shape and is combined as a whole.

As shown in Figure 3: it is just staggered that the vertical fin 22 of barrel button 2 external annulus is formed the space along the adjacent fin 15 of pedestal 1 internal ring wall; The serration 31 of turn cylinder 3 lower edge ring walls and serration 21 engagements, fin 32 is conflicted with compression spring 4 with fin 22 dislocation, cylindricality ring guide card 5, again embedding one returning spring 6 and with holder 8 fastenings.

Shown in Fig. 4-7: when pushing barrel button 2, the fin 32 that promptly promotes turn cylinder 3 is thrown off fin 15, bevelling 33 and bevelling 151 parallel contacts, when barrel button 2 mat returning springs 6 rebound, turn cylindricality 3 mats compression spring 4 discharges elastic force, make bevelling 151 slippages of fin 32,, promptly finish and push stroke until forming the space with pedestal 1 along fin 15.

Shown in Fig. 8-11, when constantly pushing barrel button 2, when making turn cylinder 3 one sound of laughing rotation displacements, Y shape guide card 71,72 of rectangle guide cards have a cylindricality ring guide card 5, its arbitrary lug 522 connects Y shape guide card 71, rectangle guide card 72 respectively, can make cylindricality ring guide card 5 connect into the switching of various different-effect functions respectively in regular turn.
