Abstract

The utility model relates to a timing mechanism of a timer, which comprises a main body, a buckle disc, a timing end and a panel. The circumference of the main body is uniformly provided with 24 windows, and both sides of the windows are vertically provided with two guide posts. The insides of the windows are provided with 24 cylinder ends, and the main body of the timing end is provided with a slot. Each of both ends of the middle part of the slot is provided with a bulge, and the two bulges are used for positioning and self locking the timing end accurately. A moving knob of the timing end is inserted into the window of the main body and is exposed out of the main body so as to be moved, and the touch block of the inclined plane of the timing end is used for touching a power switch to start electric appliances within setting time.

Description

The timer timing mechanism

The utility model relates to a kind of timer, is meant that specifically making constant speed with parts rotates the timer mechanism regularly that makes the contact action.

Existing timing mechanism can be done the constant speed rotation by driven by power, 96 flute profiles are arranged on the collar plate shape timing mechanism, the periphery of flute profile from axially plug time pin, regularly the tip touches mains switch with the timing mechanism rotation, to reach the effect that can start electrical appliance in the time of setting.Regularly the tip be used for can be freely axial taking-up or insertion from the timing mechanism, thereby it has brought following two obvious defects: regularly the tip is lost easily, in case lose, timer just can't use; Two, regularly the tip is crossed mountains out by the child easily, in the posting port or eat, does not meet safety standard.

In order to overcome the defective of above-mentioned timer, the utility model proposes the timing mechanism that a kind of timing tip is difficult for losing and crossed mountains out.

The technical solution of the utility model is a kind of timing tip that can't isolate from the outside of design.This timing mechanism contains body, button dish, the timing tip and panel to be formed, evenly have 24 windows on the body circumference, two of window edge-only has two guide pillars, 24 cylinder tips are arranged in the inboard of window, regularly tip body has groove, respectively there is a projection both sides, middle part of groove, and the spacing of these two projectioies is less than the cylinder tip of body.After the groove of the timing tip places the cylinder tip of body, move regularly the button of removing of the tip, regularly the groove of the tip and the body cylinder tip relatively move in generation radially, these two projectioies promptly are used for making regularly, and the tip is positioned exactly, and self-locking, regularly another guiding mechanism of tip radial motion be by regularly two sidewalls of the tip and body window both sides and on the slide relative of guide pillar two side lead.Regularly the window that button inserts body removed of the tip exposes partly to remove and turns round in body exterior so that move, and regularly the inclined-plane collision block of the tip starts electrical appliance in order to touch mains switch to reach at setting-up time.In order to prevent that regularly the tip comes off from timing mechanism inside or produces axial endplay, designed a button dish and incited somebody to action regularly the tip from being axially fixed on the body, make regularly the tip can only do radial displacement, and do not produce axial displacement, with tapping screw button dish and body are fixed, be stained with the panel of the time of being carved with in the outside of body, this timing mechanism just can be installed and used to timer.

The utility model adopted regularly the tip to rotate with body and can do radially on do not move, and regularly the tip is limited in the button dish, not only realizes regularly, and regularly the tip does not leave body.

The utility model is described in further detail below in conjunction with accompanying drawing embodiment:

Fig. 1 is the timing disc structure chart;

Fig. 2 is regularly the pin structure schematic diagram;

Fig. 3 is that regularly the tip inserts the timing disc state diagram.

The timing disc structure is as shown in Figure 1: timing disc (1) can insert in the time shaft of timer, time shaft imports power into by body central channel (1.4), driving timing disc rotates in time, be uniform-distribution with 24 on the circumference of timing disc and insert the regularly window (1.1) of the tip, window two sides have regularly tip positioning guide column (1.2), be provided with the post tip (1.3) at each lower window edge, guide pillar (1.2), the post tip (1.3) all are to be used for the regularly location of the tip.

Regularly pin structure is as shown in Figure 2: removing on the window (1.1) that button (2.1) can insert timing disc of the tip (2) regularly, and regularly tip body has groove (2.2), and there are two projectioies (2.3) in groove central authorities, and regularly tip sidewall has inclined-plane collision block (2.4).

Install as shown in Figure 3: the timing tip is removed button (2.1) and is passed by the inboard window of timing disc (1.1), regularly the tip (2) is by guide pillar (1.2), the post tip (1.3) location of window, regularly tip groove (2.2) inserts in the post tip (1.3), regularly its parts of the tip all have the space that moves radially at window (1.1), groove in (2.2), and regularly the button (2.1) of removing on the tip is used for external force and promotes regularly that the tip (2) moves diametrically; Before this timing device places timer body time shaft,, also be provided with a button dish rear side of the timing tip from timing disc is fixed on the timing disc in the axial direction for preventing that regularly the tip comes off or play from timing mechanism inside.

Move button (2.1) displacement during use, the timing disc body rotates in time, when time during in position regularly, and the tip collision block mains switch power-on of touching the timer body regularly.

Claims

1, a kind of timer timing mechanism contains body, button dish, the timing tip and panel composition, it is characterized in that evenly having on the body circumference 24 windows, two of window edge-only has two guide pillars, 24 cylinder tips are arranged in the inboard of window, regularly tip body has groove, respectively there is a projection both sides, middle part of groove, and the spacing of these two projectioies is less than the cylinder tip of body; Regularly another guiding mechanism of tip radial motion be by regularly two sidewalls of the tip and body window both sides and on the slide relative of guide pillar two side lead, the window of removing button insertion body of the timing tip exposes removes button in body exterior, and regularly the inclined-plane of the tip is provided with in order to touch the collision block of mains switch.
