Specific implementation mode

Below in conjunction with the accompanying drawings, a specific implementation mode of the utility model is described in detail, it is to be understood that this The protection domain of utility model is not restricted by specific implementation.

A kind of door body locking mechanism of oven of the utility model is as depicted in figs. 1 and 2, includes the lock on babinet 3 Body 1 and it is arranged on chamber door 4 with 1 matched locking part 2 of lock body, the opening of 4 sealed container door 4 of chamber door on the chamber door 4 There is door knob 41, can easily open chamber door 4；It is sealed by lock body 1 and locking part 2, it can effectively avoid oven worked Cheng Zhong, chamber door 4 automatically turn on, the heat scald user come out in babinet 3.

As shown in Figure 1, Figure 2 and Figure 3, it reserves and has the gap between the lower surface on 3 upper port edge of the upper surface of chamber door 4 and babinet 31, lock body 1 includes lock 11, latch hook 12, axis pin 13 and torsional spring 14, and lock 11 is the plate body structure that middle part is arched upward and fixed installation On the upper surface of 3 inner cavity of babinet, latch hook 12 is that hook part 121 is provided on the left of slab construction and its plate body, and latch hook 12 is logical Axis pin 13 is crossed to be rotatably connected on the arch face 111 of lock 11；Latch hook 12 is extended to by the gap 31 between babinet 3 and chamber door 4 Outside babinet 3, the part that latch hook 12 extends to outside babinet 3 is provided with handle 123, by handle 123 can conveniently make latch hook 12 around The rotation of axis pin 13, thus easily realize the locking or unlock of the hook part 121 and locking part 2 of latch hook 12, it is preferably sealed Portion 2 is the column structure or cyclic structure for being fixedly connected on 4 upper end of chamber door, the channel-shaped knot being also opened on 4 inner surface of chamber door Either cavernous structure links column structure or cyclic structure or groove-like structure or hole to structure by hook-shaped hook part 121 Shape structure realizes the locking between chamber door 4 and babinet 3；To improve the reliability locked between chamber door 4 and babinet 3, it is preferable that turn round Spring 14 is set on axis pin 13, and the precalculated position of 12 plate body of latch hook is provided with the block 122 of protrusion, and the both ends of torsional spring 14 are in latch hook It is interfered respectively with the side wall of arch face 111 and block 122 in 12 rotation processes, in the case of by outer force effect, not turn round Spring 14 can drive latch hook 12 to reset, and in the case where chamber door 4 is closed, latch hook 12 is linked with 2 phase of locking part always.

Further, latch hook 12 is provided with drawing for the wedge shape for guiding locking part 2 to slide into hook part 121 when being closed for chamber door 4 Guide face 124, in 4 closing process of chamber door, by the effect of guide surface 124, locking part 2 collides the end face of latch hook 12 along guide surface 124 slide into during hook part 121, and latch hook 12 rotates to the right, and 14 deformation of torsional spring, locking part 2 is slid completely into hook part 121 Interior, torsional spring 14 drives latch hook 12 to move downward and is linked with locking part 2.

When opening chamber door 4, being turned right latch hook 12 by handle 123 so that hook part 121 is detached from locking part 2, to Can easily chamber door 4 be pulled down by door knob 41 to open；When closing chamber door 4, with certain power, chamber door 4 is pushed, in guide surface 124 and torsional spring 14 under the action of, can easily realize locking part 2 and latch hook 12 links locking.

Disclosed above is only the embodiments of the present invention, and still, the utility model is not limited to this, any ability What the technical staff in domain can think variation should all fall into the scope of protection of the utility model.
