The return mechanism preferably comprises a return lock sleeve and an elastic element; the return lock sleeve is sleeved on the lock tongue and is fixedly connected with the lock tongue; one end of the elastic element is fixed on the cabinet door, and the other end is fixed on the return lock sleeve, and the installation position of the elastic element can lead to an elastic force on the lock tongue when the lock tongue leaves the opening position. The linkage lock is provided with the return mechanism, so when the lock tongue stays at the rotary state and the lock tongue leaves the opening position, the return mechanism can force the lock tongue to return to the opening position, and the situation that the lock tongue or a suspension arm is damaged caused by the collision between the lock tongue and the suspension arm can be avoided.
Description
Technical field
The utility model relates to mechanical field, is specifically related to a kind of lockset dead bolt automatic reset mechanism and uses the cupboard of this link lock.
Background technology
Link lock (also being positive lock or side lock) is widely used in equipment such as cupboard, drawer, casing, and this lockset is realized the sealed of cabinet door and cabinet by rotation dead bolt lifting locking bar.
Fig. 1 is a conventional linkage lock opening schematic diagram.Fig. 2 is a conventional linkage lock locking state schematic diagram.Below in conjunction with Fig. 1, Fig. 2 conventional linkage lock construction and operating principle are described.
As shown in Figure 1 and Figure 2, link lock 100 comprises tapered end 1, locking bar 2 and baffle plate 3, and tapered end 1 and baffle plate 3 are installed on the cabinet door 200, and locking bar 2 is installed on the cabinet 300.Tapered end 1 comprises dead bolt 10, lock core 11, and the key (not shown) is inserted lock core 11 and rotated, and can control dead bolt 10 rotations.When key did not insert lock core 11, this dead bolt 10 can't be rotated by locked.Locking bar 2 comprises connecting rod 20, first cantilever 21, second cantilever 22 and bumping post 23.First cantilever 21, second cantilever 22 and bumping post 23 are vertically fixed on connecting rod 20 surfaces, and space and dead bolt 10 external diameters between first cantilever 21 and second cantilever 22 are suitable, connecting rod 20 is fixed in the track 301 of an above-below direction of offering on the cabinet 300, and be limited in this track 301 by two transverse baffles 302, make it can not break away from this track 301, at that time can slippage up and down in this track 301.Under the situation that does not have the external force effect, described locking bar 2 can be owing to slide into the extreme lower position of this track 301 under the effect of gravity.
Suppose that cabinet door 200 is shown in an open position, and dead bolt 10 has been positioned under the situation of enable possition (being extreme lower position) and has closed cabinet door 200.At this moment, described locking bar 2 is not owing to there is the external force effect to be in the extreme lower position of track 301, and the installation site of tapered end 1 makes dead bolt 10 after cabinet door 200 is closed, and can insert just between first cantilever 21 and second cantilever 22.Same because locking bar 2 is positioned at the extreme lower position of track 301, baffle plate 3 the installation site on the cabinet door 200 be located at bumping post 23 above.Like this, cabinet door 200 is not subjected to any restriction, can freely open.Fig. 1 promptly illustrates this kind situation.After cabinet door 200 is closed, when needing locking cabinet door 200, need by key actuated dead bolt 10 Rotate 180 degree, dead bolt 10 moves to locked position (being the extreme higher position), simultaneously, dead bolt 10 promotes first cantilever 21 and moves up, and the described connecting rod of fixing with first cantilever 21 20 moves upward to the extreme higher position thereupon, be fixed on bumping post 23 on the connecting rod 20 along with connecting rod 20 moves to the position that articulates with baffle plate 3, promptly the position of bumping post 23 makes it can block baffle plate 3.Cabinet door 200 and can't be opened because baffle plate 3 is blocked 23 and blocks by described, realizes the locking to cabinet door 200.Extract key this moment out, and described tapered end 1 is by locked, and dead bolt 10 can't rotate, and in the extreme higher position, like this, cabinet door 200 just keeps closed condition to locking bar 2 by dead bolt 10 retainings.Open cabinet door 200 if desired, then need to insert key, and rotation dead bolt 10, make dead bolt 10 get back to the enable possition.Fig. 2 promptly illustrates this kind situation.
Suppose that cabinet door 200 is shown in an open position, and dead bolt 10 has been positioned under the situation of locked position (being the extreme higher position) and has needed to close cabinet door 200.At this moment, described locking bar 2 is not owing to there is the external force effect to be in the extreme lower position of track 301.The installation site of tapered end 1 makes dead bolt 10 after cabinet door 200 is closed, and dead bolt 10 is positioned on first cantilever 21.At this moment, this link lock can't be tight with door lock, if wish locking cabinet door 200, must open cabinet door 200, and dead bolt 10 is rotated to the enable possition, closes cabinet door 200 once more, locking cabinet door 200..
Another situation is, cabinet door 200 is shown in an open position, and dead bolt 10 is under external force between enable possition and locked position.At this moment, close cabinet door 200, then the position of dead bolt 10 is bumped against it probably with first cantilever 21 or second cantilever 22, if it is bigger to close the strength of cabinet door 200, the impaired situation of dead bolt or cantilever then may occur.
Summary of the invention
At above-mentioned defective, the technical problem that the utility model solves is, a kind of link lock is provided, this link lock can be owing to dead bolt does not rotate to the enable possition, and can't lock the cabinet door behind the door closing cabinet, and dead bolt and cantilever bump the situation that causes dead bolt to damage.The utility model provides a kind of cupboard that uses above-mentioned link lock simultaneously.
The link lock that the utility model provides comprises the tapered end and the baffle plate that are installed on the cabinet door, is fixed on the locking bar on the cabinet, it is characterized in that also having the resetting-mechanism that is connected with the dead bolt of described tapered end.
