Abstract
The utility model discloses a three-point lock device which comprises a middle lock mechanism, an upper lock mechanism and a lower lock mechanism, wherein the lower lock mechanism and the upper lock mechanism are symmetric. The middle lock mechanism comprises a middle lock piece, a lock cylinder and a rotating wheel, the upper lock mechanism comprises a lock piece, a connecting rod, a spring limiter and a spring, the lock cylinder and the spring limiter are fixed on an inner door board of a cabinet door, one end of the connecting rod penetrates through the spring limiter to be connected onto the rotating wheel while the other end of the connecting rod is connected with the lock piece, the head of the lock piece has a slope structure, one end of the spring is connected to the spring limiter while the other end of the spring is connected onto the connecting rod, the lock cylinder drives the rotating wheel to rotate, the rotating wheel drives the middle lock piece to move bilaterally and further drives the connecting rod to move vertically, and the connecting rod is provided with a plurality holes. The three-point lock device has the advantages that an operator can close the door by pushing the cabinet door readily when leaving, and thereby operation is convenient and safe; and assembly requirements during production are also simple.
Description
Technical field
The utility model relates to a kind of 3 locking devices of cupboard, directly pushes away 3 locking devices of pass when particularly the cabinet door is higher or low.
Background technology
The equipment cupboard that uses in the daily production can relate to 3 locks, promptly is distributed with locking plate in the middle part and the top and the bottom of cabinet door.Normally close the cabinet door in the use through the handle on the trip lock.
But when running into cupboard when higher, the operator just need just can take handle with ladder and accomplish and close the door; When cupboard was low, the operator need bend over just can take the handle completion and close the door.When existing 3 locking devices were applied in the higher or lower cupboard of these cabinet doors, matching requirements were high when not only troublesome poeration, and existing 3 locking devices was produced.
The utility model content
The purpose of the utility model provides a kind of 3 locking devices, closes the door once pushing away to accomplish conveniently when guaranteeing that the operator leaves, to overcome the deficiency of prior art.
For realizing above-mentioned purpose, the utility model is realized through following technical scheme:
A kind of 3 locking devices comprise middle part latch mechanism, upper lock mechanism and bottom latch mechanism, and bottom latch mechanism and upper lock mechanism are symmetrical structure; The middle part latch mechanism comprises middle part locking plate, lock core and swiveling wheel, and upper lock mechanism comprises locking plate, connecting rod, spring locating part and spring, and wherein lock core and spring locating part are fixed on the cabinet door inner door panel; Connecting rod one end passes the spring locating part and is connected on the swiveling wheel; The other end connects locking plate, and the locking plate head has ramp structure, and spring one end is connected to the spring locating part; The other end is connected on the connecting rod; The rotation of lock core driven rotary wheel, swiveling wheel drives the middle part locking plate and does side-to-side movement, and swiveling wheel also drives connecting rod and moves up and down.
On the said connecting rod a plurality of holes can also be set, spring one end is realized the adjusting of elastic force through cooperating with different holes.
At closing time; Promote door-plate, make the ramp structure of locking plate head run into doorframe, make it produce downwards, upward pressure through ramp structure; Because locking plate is fixedly connected with connecting rod; Downward pressure is through the transmission driven rotary wheel rotation of connecting rod, and swiveling wheel drives the middle part locking plate and inwardly moves, and spring is in the pretensioned state under tension simultaneously; When door had closed, the casing doorframe was provided with lockhole, and connecting rod makes progress, moves downward through the pulling force of spring; Make locking plate get in the lockhole of casing doorframe; Driven rotary wheel reverse rotation simultaneously, swiveling wheel drives the middle part locking plate and outwards moves, and gets in the lockhole of corresponding casing doorframe; Just utilize the strength of spring to reset, reach the purpose of closing the door.
The beneficial effect of described a kind of 3 locking devices of the utility model is: when being applied in the higher or lower cupboard of cabinet door, conveniently can accomplishing and close the door operation facility, safety once pushing away the cabinet door when operator leaves; And matching requirements are also simple in the manufacturing process.

The specific embodiment
Like Fig. 1, Fig. 2, shown in Figure 3, be respectively overall structure sketch map, the closed condition of 3 locking devices of the utility model and locking plate structural representation when closing critical point.
A kind of 3 locking devices comprise middle part latch mechanism, upper lock mechanism and bottom latch mechanism, and bottom latch mechanism and upper lock mechanism are symmetrical structure; The middle part latch mechanism comprises middle part locking plate 5, lock core and swiveling wheel 6, and upper lock mechanism comprises locking plate 1, connecting rod 2, spring locating part 3 and spring 4, and wherein lock core and spring locating part 3 are fixed on the cabinet door inner door panel 7; Connecting rod 2 one ends pass spring locating part 3 and are connected on the swiveling wheel 6; The other end connects locking plate 1, and locking plate 1 head has ramp structure 11, and spring 4 one ends are connected to spring locating part 3; The other end is connected on the connecting rod 2; 6 rotations of lock core driven rotary wheel, swiveling wheel 6 drives middle part locking plate 5 and does side-to-side movement, and swiveling wheel 6 also drives connecting rod 2 and moves up and down.
On the said connecting rod 2 a plurality of holes are set also, spring 4 one ends are realized the adjusting of elastic force through cooperating with different holes.
At closing time; Promote door-plate 7, make the ramp structure 11 of locking plate 1 head run into doorframe 8, make locking plate 1 produce respectively downwards, upward pressure through ramp structure 11; Because locking plate 1 is fixedly connected with connecting rod 2; Transmission driven rotary wheel 6 rotations of pressure through connecting rod 2 have cam gear to change the rotation of swiveling wheel 6 into middle part locking plate 5 and inwardly moves on the swiveling wheel 6, while spring 4 is in the pretensioned state under tension; When door-plate moves to Fig. 3 position, the inside again mistake of door-plate 7 a bit because casing doorframe 8 is provided with lockhole; The pressure that 8 pairs of locking plates of doorframe 1 produce disappears, and upper and lower connecting rod 2 made progress respectively, moved downward through the pulling force of spring 4 this moment, makes locking plate 1 get in the lockhole of casing doorframe 8; Driven rotary is taken turns 6 reverse rotations simultaneously; Swiveling wheel 6 drives middle part locking plate 5 and outwards moves, and gets in the lockhole of corresponding casing doorframe 8, just utilizes the strength of spring 4 to reset; Make and reach the purpose of closing the door by three locking plate total deadlocks.
