Specific implementation mode
According to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, the present invention is under lock body upper cover 1, lock body
On the basis of lid 2, lock tongue 3, sliding block 4, spring 5, microswitch 6, feature is that the lock body upper cover 1 passes through with lock body lower cover 2
Buckle is spliced into lock body up and down, lock body front end is provided with lock tongue jack 15, the tongue piece 8 of lock tongue 3 is inserted into lock from lock tongue jack
In vivo, the arranged on left and right sides setting fluted 7 of tongue piece 8, is provided with microswitch 6 in lock body on the position opposite with lock tongue 3,
The mandril of microswitch 6 is inserted 16 and is entered into mandril sliding slot 13 to the extension of 3 direction of lock tongue, and can connect with the tongue piece 8 of lock tongue 3
It touches；8 left and right both sides of tongue piece positioned at lock tongue 3 in lock body are respectively arranged with sliding block 12, and the sliding block end face opposite with tongue piece is curved
Curved surface 11, the flexure plane 11 of sliding block are mutually adapted with the groove 7 of lock tongue, are litter in the other end of sliding block, bullet is cased on litter
Spring 5.The flexure plane end face of the sliding block 4 is fastened with the groove of lock tongue 3 under the action of the spring, has limit to make the sliding of sliding block 4
With.The sliding block 4 is mounted in lock body, and the glide direction of sliding block 4 is vertical with lock tongue 3.The lock body is lock body upper cover
1, lock body lower cover 2 is spliced to form in the mode of liner reinforcing rib, fixed card buckle and fixing screw hole.The sliding block 4 is to pass through
The installation of litter sliding slot 14 is fixed in lock body, the mandril sliding slot 13 be in lock body lock tongue installation cavity and microswitch installation cavity it
Between the bar groove that is connected.
Dish washing machine door latch mechanism provided in an embodiment of the present invention, by carrying out locking lock tongue under the cooperation of sliding block 6 and spring 7
5, it effectively simplifies the structure of lock body component 1 and reduces the overall dimensions of lock body component 1, so that lock body component 1 can
It is installed on liner reinforcing rib.In this way, lock tongue 5 by being installed in dish-washing machine door body, lock body component 1 being installed on liner by it
On reinforcing rib, and since the build of lock tongue 5 is smaller, therefore, it effectively reduces dish washing machine door latch mechanism and pacifies on dish-washing machine body
The occupied space of dress so that dish washing machine door latch mechanism provided by the invention can be applied on the relatively thin dish-washing machine of door body, fully protect
Sealing reliability of the relatively thin dish-washing machine of door body in washing process has been demonstrate,proved, and has enhanced dish washing machine door latch mechanism and washes the dishes in difference
The versatility used on machine.
The operation principle of dish washing machine door latch mechanism provided in an embodiment of the present invention is as follows：
As shown in Fig. 2, in the state that dish-washing machine door body assembly is in and opens, lock tongue 5 and lock body component 1 are in and mutually divide
From state, each component is in original state (mandril of spring 7 and microswitch 10 is uncompressed) in lock body component 1, this
When, microswitch 10 is not turned on, therefore door body assembly is in the state opened, at the control circuit to ensure dish-washing machine
In off-state, the security reliability that product uses ensure that.
As shown in figure 3, during dish-washing machine lock tongue 5 is inserted into lock body component 1, lock tongue 5 can push the head of sliding block 6,
Two sliding blocks are pushed open from left and right directions respectively in the case that spring is compressed, the head of lock tongue 5 starts top pressure fine motion at this time
The mandril of switch 10, when spring is gradually compressed lock tongue 5 during pushing the head of sliding block 6, until being pressed by spring
Contract the maximum amount of process, and then lock tongue 5 continues to press on the head of sliding block 6, and spring starts to gradually reduce decrement at this time, works as lock tongue
5 in the groove that two slider ends are formed card insertion in place when, sliding block 6 can be under the effect of the elastic force of spring 7 by the groove of lock tongue 5
It is clamped in the groove of two slider ends formation (spring 7 restores to the original state at this time).
As shown in figure 4, in the state that dish-washing machine door body assembly is in and closes, lock tongue 5 slides card insertion in two slider ends
Portion formed groove it is interior, the mandril of microswitch 10 is in confined state in lock body component 1, at this point, 10 quilt of microswitch
It connects, therefore door body assembly is to ensure that the function of product so that the control circuit of dish-washing machine can be connected in the state closed
Use normality.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
Any modification, equivalent replacement or improvement etc., should all be included in the protection scope of the present invention made by within refreshing and principle.
