Abstract

The utility model relates to an anti-locking mechanism of a toaster, which comprises a toaster body and a sliding panel which is provided with a bread bracket and a switch starter. The sliding panel is in sliding connection with a connecting rod of the bread bracket. The connecting rod is provided with a stop block. The bread bracket takes an L shape. The connecting rod is arranged vertically and is put through an upper panel and a lower panel of the sliding panel, and the end part is provided with the stop block. The section of the sliding panel is C-shaped. The lower part of a front board is fixedly connected with a magnetic piece component and the switch starter. The upper panel or the lower panel is connected with a tension spring, and the other end of the tension spring is fixedly connected with the inner top surface of the toaster body. The sliding panel of the anti-locking mechanism can move up and down freely within the range limited by the stop block of the connecting rod of the bread bracket; even when the bread bracket is locked due to an external factor, the sliding panel can still be replaced normally under the action of the tension spring, which ensures that the switch starter does not act on a switch spring plate and ensures that a power supply is under the state of disconnection completely after the time set for toasting finishes. The anti-locking mechanism has simple and reasonable structure, low manufacturing cost, simple operation and high safety performance.

The anti-jamming mechanism of toaster

Technical field

The utility model relates to the anti-jamming mechanism of a kind of toaster, particularly a kind of toaster.

Background technology

Existing toaster is for satisfying anti-jamming function (or claiming automatic circuit break function), generally need two to three sliding panel to realize, because of parts many, the assembling difficulty, quality also is difficult to control, examine goods and client's complaint in, often have because of interfering caused anti-jamming inefficacy between the sliding panel mutually, cost is also higher relatively.The anti-jamming protection mechanism of a kind of toaster is disclosed among the China Patent No. ZL200520056792.0; the technical problem that solves is rusk to occur to be stuck; or balladeur train and other parts are cut off the electricity supply when being stuck automatically; toaster second balladeur train and vertical shaft form and are slidingly connected; be fixed with electric switch seat and rocking arm supporting base on the base plate; an end of hinged rocking arm on the rocking arm supporting base; rocking arm middle part is connected with first adjutage of the guide hole that passes on second balladeur train; the rocking arm middle part is connected with extension spring with second balladeur train upper end; the free end of rocking arm contact with the movable contact of electric switch seat when extreme lower position; and the fixed contact of electric switch seat is contacted with movable contact; when balladeur train occurring and be stuck; in the middle part of rocking arm with second balladeur train under the effect of the extension spring that is connected; the free end of rocking arm moves up; no longer oppress the movable contact of electric switch seat, makes the fixed contact of electric switch seat contact disengagement with movable contact, cuts off the electricity supply.This complex structure, cost cost height is prone to part and interferes with each other, and causes disabler.

The utility model content

The purpose of this utility model is to provide a kind of anti-jamming mechanism of simple and reasonable, part is little, security performance is high toaster, to overcome weak point of the prior art.

Press the anti-jamming mechanism of a kind of toaster of this purpose design, the sliding panel that includes body of heater and be provided with bread carriage and switching starter, its architectural feature is that sliding panel is slidingly connected on the connecting rod of bread carriage, connecting rod is provided with limited block, and sliding panel can move up and down in the limited block limited range.

Described bread carriage is L-shaped, and connecting rod vertically is provided with, and runs through the upper and lower plates of sliding panel, and the end is provided with limited block, and limited block is wing or Φ shape.

Described sliding panel cross section is c-shaped, the connecting rod of the corresponding bread carriage of upper and lower plates is provided with strip or Φ shape jack, header board top is fixedly connected with handle, the bottom is fixedly connected with magnetic chip module and switching starter, upper plate or lower plate are connected with extension spring, and the extension spring other end is fixedly connected on the body of heater inner top surface.Sliding panel is provided with the jack of assembling bread carriage, and the connecting rod of bread carriage inserts jack, its end is carried out bending or reverses, and prevents that the bread carriage from deviating from sliding panel and separates to form limited block.

Be connected with slide rail in the described body of heater up and down, slide rail runs through the upper and lower plates of sliding panel, and corresponding magnetic chip module of inner bottom surface and switching starter are respectively arranged with electromagnet and switch module.The movable contact that switch module includes fixed contact and is electrically connected with switch shrapnel.

Sliding panel of the present utility model can freely move up and down in the limited block limited range of bread carriage connecting rod, even the bread carriage is stuck by extraneous factor, sliding panel can both normally reset under the extension spring effect, make switching starter ineffective to switch shrapnel, after the toast bread time that guarantee to be provided with finished, power supply was in the state that disconnects fully.It is simple and reasonable, cost of manufacture is low, easy and simple to handle and security performance height.
