Description

The improvement timing mechanism of timer

The utility model relates to timing mechanism, refers to a kind of timing mechanism of electrical equipment timer especially.

The general timer of institute's employing electrical equipment on the market, the timing mechanism system that it had is by a timing rotating disk that is meshed with the travelling gear of timer, and a plurality of latches that insert on the timing rotating disk are formed, wherein this timing rotating disk on its circumference with one group of two pin-and-hole and radially equidistantly arrange 48 groups mode and design, aforesaid latch then has two different colonnettes of length by one and is constituted, by the long column of aforementioned latch or the short column position difference of one group of pin-and-hole wherein on the timing rotating disk, and the touch switch that comes control timer is path or off state, so forms a kind of timing mechanism of timer; The shortcoming that this timing mechanism had is described below:

(1) appended latch has only 6 on the timer, and 48 groups of pin-and-holes are arranged on the timing rotating disk, so this timer is under the situation of latch number deficiency, path that can't round-the-clock control apparatus or open circuit, and the user then causes timer to use if accidentally latch is lost.

(2) aforesaid latch and timing rotating disk are separate design, the user is setting start during the period, might be because the wrong plug of latch order, and cause the misoperation of electrical equipment, increase user's puzzlement on foot, again, latch causes the abrasion or even the damage of latch under the situation that often insertion pin-and-hole or pin-and-hole are extracted.

The purpose of this utility model provides a kind of timing mechanism of timer, and it is easy to manufacture, and the bulk strength height can arbitrary period or multi-period setting in a day 24 hours, and has timer inside and can utilize the space big, the characteristics that the timing setting sense of touch is good.

For achieving the above object, the timing mechanism of the timer that the utility model provides, system is by a timing rotating disk, at least more than one setting pin, and one the panel that is fixedly arranged on timing rotating disk top form, wherein this timing rotating disk is one circular, its center is provided with an internal gear that can be meshed with the timer travelling gear, its architectural feature is, one end of this timing rotating disk, by excircle with axially to lower recess one annular recess, its outside cell wall is the inclined-plane of the suitable angle of an inclination, and around the groove radially to be provided with at least more than one slotted eye, aforesaid setting pin then is installed in this slotted eye, a fastening part is respectively extended in these setting pin both sides, make and set pin by being blocked in aforesaid inclined-plane, and can be radially to pull rotation in annular recess, the other end of this timing rotating disk then extends downwards corresponding to aforementioned slotted eye place and the flexible buckle element of at least more than one tool of transferring, and different positions is arranged to distinguish the path or the off state of timing mechanism when making aforementioned setting pin pull rotation in annular recess by this buckle element.

The utlity model has following advantage:

1, becomes a bending arc shape owing to set pin, increase the bulk strength of this setting pin by the level and smooth cambered surface that it had, and this setting pin respectively extends a fastening part to both sides and uses the annular recess that is had with the timing rotating disk and match, owing to only require that the setting pin can be movable on the timing rotating disk, therefore aforementioned the two quality of fit does not need too high, thereby reduces the degree of difficulty on the processing procedure.

2, on the utility model timing rotating disk,, change internal gear into, increase the inner available space of timer by this by external gear with travelling gear meshed gears pattern.

3, the utility model is if on the slotted eye that the timing rotating disk is had, stick with and set pin, then the user is in one day 24 hours, do arbitrary period or multi-period setting, and utilize above-mentioned panel, to set the pin retaining and be held on the timing rotating disk, so the user needn't worry whether the setting pin can be lost deficient.

4, pull because set to sell to tie up on the timing rotating disk, and utilizing panel to make retaining holds, therefore needn't be setting pin by inserting on the timing rotating disk or extracting, and avoided because the error on artificial the setting, cause the misoperation of electrical equipment, again, do not need to separate, therefore can avoid setting the abrasion of pin or even damaging by the slotted eye of timing rotating disk because set pin.

5, the utility model utilizes the elasticity that buckle element had of above-mentioned timing rotating disk, make and set pin when the appropriate location of pulling to buckle element, can make by aforesaid elasticity and set the set condition that pin slides to path voluntarily or opens circuit, allow the user that better sense of touch is arranged when setting timer.
