Abstract
The invention discloses an automatic lock catch mechanism which is used between an upper cover and an outer shell of an intelligent rice cooking device. The automatic lock catch mechanism comprises a lock base, a moving shaft, a lock face cover, two magnets, a spring and a connecting sheet. According to the specific scheme, one magnet is fixed in a counter bore of the moving shaft, the moving shaft is installed into the lock base in the regulated direction, the spring is arranged on the moving shaft in a sleeved mode, the lock face cover is buckled on the lock base, the other magnet is installed into a counter bore of the lock face cover, and then the mechanism is assembled. Six assembled lock catch mechanisms are fixed at the corresponding positions of the outer shell of the whole device respectively, and the six connecting sheets are installed into the corresponding grooves in the upper cover of the whole device respectively. The upper cover of the whole device is buckled on the outer shell of the whole device in the regulated direction, and then the upper cover can be tightly buckled with the outer shell. The principle that like poles repel and unlike poles attract of the magnets and the difference between the attraction force (or repelling force) of the large magnet and the attraction force (or repelling force) of the small magnet are utilized, and the locking and unlocking of a lock catch are achieved through the compression resilience force of the spring.
Description
Technical field
The present invention relates to a kind of automatic locking mechanism of upper cover and shell of intelligent rice cooking utensil, especially a kind of interactional latching device that utilizes attraction and the spring thrust of magnet.
Background technology
The enclosing cover of present all kinds of household electronic products and the connection of shell are all that screw connects or plastic cement button bit connects, such bind mode can arbitrarily be opened, for some special household electronic products, if user can independently arbitrarily open enclosing cover, can there is potential safety hazard.Therefore, design a kind of automatic locking mechanism that had not only facilitated installation but also only had specialized maintenance personnel easily to open just necessary.
Summary of the invention
In order to meet the needs of some special electric equipment products, be particularly used on a kind of intelligent rice cooking utensil, the invention provides a kind of low cost, automatic locking mechanism simple for structure, this mechanism only has specialized maintenance personnel easily to open, and mechanism fastens convenient.
This mechanism comprises: lock base, shifting axle, locking face lid, magnet (two), spring and connection sheet.
The technical scheme adopting is: a magnet is fixed in the counterbore of shifting axle, shifting axle direction is in accordance with regulations packed in lock base, on shifting axle, be inserted in spring, locking face cover buckle is combined on lock base, then in the counterbore of locking face lid, pack another piece magnet into, this mechanism just assembles.Six latching devices that assembled are separately fixed to the correspondence position of machine shell, six connection sheets are respectively charged in the corresponding groove of complete machine upper cover.By complete machine upper cover in accordance with regulations direction be fastened on machine shell (six connection sheets in upper cover insert respectively in the axle of six snap closes of shell), upper cover and shell are just tight sealed like this.With large magnet, the sealed place at complete machine circles respectively professional, and six snap closes are just opened automatically, and upper cover and shell are just separable.
Beneficial effect:
This mechanism has utilized the principle that the homopolarity of magnet repels mutually, heteropole attracts mutually, has utilized the attraction (or repulsive force) of large magnet and small magnet variant, in conjunction with the compression and back elastic force of spring, realizes the sealed of snap close and opens.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments Dui Ben mechanism, be described further.
Accompanying drawing 1 Shi Ben mechanism plane structure chart (locked state);
Accompanying drawing 2 Shi Ben mechanism plane structure charts (open mode);
Accompanying drawing 3 Shi Ben mechanism exploded views;
Accompanying drawing 4 Shi Ben mechanism axonometric drawings.
The specific embodiment
See in accompanying drawing 3 magnet (3) is fixed in the counterbore of shifting axle (2), shifting axle (2) direction is in accordance with regulations packed in lock base (1), on shifting axle (2), be inserted in spring (4), locking face lid (5) is fastened on lock base (1), then in the counterbore of locking face lid (5), pack another piece magnet (6) into, this mechanism just assembles.Six latching devices that assembled are separately fixed to the correspondence position of machine shell, six connection sheets (7) are respectively charged in the corresponding groove of complete machine upper cover.By complete machine upper cover in accordance with regulations direction be fastened on machine shell (six connection sheets in upper cover insert respectively in the axle of six snap closes of shell), upper cover and shell are just closely sealed like this.With large magnet, the sealed place at complete machine circles respectively professional, and six snap closes are just opened automatically, and upper cover and shell are just separable.
Claims (1)
1. the automatic locking mechanism of the upper cover of an intelligent rice cooking utensil and shell, it is characterized in that: two blocks of magnet and spring are housed in this latching device, the principle that utilize the homopolarity of magnet to repel mutually, heteropole attracts mutually, utilize the attraction (or repulsive force) of large magnet and small magnet variant, in conjunction with the compression and back elastic force of spring, realize the sealed of snap close and open.
