Abstract

The invention discloses a kind of locking system by setting locking oven door on casing, closed baking box makes oven door and casing more tight closure by locking knob behind the door, reduce the space between oven door and casing, the loss of heat is reduced, improves the efficiency of heating surface, simultaneously, when unlocking oven door, need to press the button for making lock depart from latch hook after unlocking locking knob, oven door could be allowed to open, improve security.

Description

A kind of baking box with novel locking device

[technical field]

The present invention relates to a kind of baking box with novel locking device.

[background technology]

During existing oven door closure, simply by the lock that the latch hook being arranged in oven door is simply fastened on to casing Cover, by the random folding of handle can in oven door, therefore have the following disadvantages, when one side baking box works, baking box Space between door and casing is larger, it is impossible to functions well as sealing function so that heat is from space during baking box works Leakage so that non-uniform temperature in casing；In another aspect heating process or after the completion of heating, oven door can be opened arbitrarily Close, easily cause danger.

[content of the invention]

Instant invention overcomes the deficiency of above-mentioned technology, there is provided a kind of baking box with novel locking device, by case The locking system of locking oven door is set on body, improves the sealing and its security of baking box.

To achieve the above object, present invention employs following technical proposal：

The beneficial effects of the invention are as follows：

Locking system of the invention by setting locking oven door on casing, closed baking box are made by locking knob behind the door Oven door and casing more tight closure, reduce the space between oven door and casing, reduce the loss of heat, improve heating effect Rate, meanwhile, unlock oven door when, it is necessary to unlock locking knob after press make lock depart from latch hook button, can just say oven door Open, improve security.

Fig. 2 is schematic diagram before locking of the present invention；

Fig. 3 is schematic diagram after locking of the present invention；

Fig. 4 is locking system schematic diagram of the present invention.

[embodiment]

It is described in further detail below in conjunction with the accompanying drawings with embodiments of the present invention：

As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of baking box with novel locking device, includes casing 1 and oven door 2, the casing 1 is provided with locking knob 3, and the locking knob 3 is connected with to be rotated and mobile connector 4 with locking knob 3, Lock 5 is hinged with the connector 4, the oven door 2 is provided with the latch hook 6 that lock 5 is fastened when oven door 2 closes, institute State lock 5 to move with connector 4 and tense latch hook 6 and carry out locking oven door 2, connecting rod 7, the case are connected with the lock 5 Body 1 is provided with the button 8 for making connecting rod 7 be rotated around connector 4 with 5 pin joints of lock, and the connecting rod 7 is provided with after making rotation The first spring that connecting rod 7 resets, the lock 5 rotate with connecting rod 7 and depart from latch hook 6 to unlock oven door 2.

Such as Fig. 2, Fig. 3 and Fig. 4, the locking knob 3 has the cam 9 rotated with locking knob 3, the connector 4 The catch 10 being connected with cam 9 is provided with, the connector 4 rotates with cam 9 and promotes catch 10 to make connector 4 to casing 1 Interior movement, the connector 4 are provided with the second spring for resetting connector 4.

Operation principle：As shown in Figure 4, it is necessary to during locking oven door 2, closed baking box door 2, the latch hook 6 in oven door 2 is with setting The lock 5 being placed on casing 1 fastens, and user's turn locking knob 3 carries out locking, make the cam 9 that is arranged on locking knob 3 with It is rotated, and cam 9 promotes the catch 10 being arranged on connector 4 to be moved into casing 1 so that lock 5 also moves with connector 4 And move, so as to tense latch hook 6, make oven door 2 and casing 1 closer, improve air-tightness, reduce thermal loss, improve heating Efficiency；When needing to unlock oven door 2 after the completion of heating work, user's turn locking knob 3 is unlocked, and makes to be arranged at locking Cam on knob 3, which rotates with it, to be unlocked, the turn of cam 9 to original state, is arranged at connector 4 with being arranged on For first spring reset to original state, lock 5 no longer tenses latch hook 6, and then user needs button press 8, the connecting rod 7 with The contact surface of button 8 is inclined-plane, during button 8 is pressed, connecting rod 7 drives lock 5 around the hinge of connector 4 and lock 5 Contact rotates, and lock 5 is departed from latch hook 6, so as to open oven door 2, substantially increases the security of baking box.

The latch hook 6 is two, and the lock 5 is two, when lock 5 pull locking oven door 2 with latch hook 6, by Power evenly, preferably carries out locking.
