Description
Technical field
The utility model belongs to gate technical field of hardware, specifically, the utility model is related to a kind of with magnet
Door chain.
Background technology
Door chain is a kind of locking metallic bond on the inside of gate.Door chain is as a kind of common reinforcement door lock
Safety device is widely used among all kinds of hotels and daily house.Common door chain is as shown in Figure 1 and Figure 2.Door chain is by gold
Belong to material to be made.In use, one end of door chain is fixed on doorframe or wall, other end is equipped with lock, can stick into
It is fixed in the sliding slot on door, plays the anti-theft function for strengthening door lock.
When hanging up properly door chain, door gap maximum can be only opened to 5 centimetres or so.In this case, people is can not to lead to
It crosses, hand can not also put in opening door chain from gap, this guarantees when owner does not confirm visitor's identity, will not meet with
To other side surprise attack or swarm into.In addition, there is the design pattern that metallic bond is replaced with metallic rod, it is also using upper in design
For it is identical the considerations of.
Under normal circumstances, door chain can bring certain safeguard protection to act on to user.It is but existing antitheft
There are some potential safety problemss for chain.For example, the concussion of door chain and lock is easily caused when door is by switch energetically back and forth, it can
Lock can be made to be disengaged from the access aperture of the sliding slot end, its protective action is caused to fail.In addition criminal is by using L-type steel silk
Or other tools, it stirs and latches to the sliding slot end and disengaging makes door chain fail.
Utility model content
The utility model provides a kind of door chain with magnet, improves the stability of door chain locking, avoid because
Chain protects failure caused by vibrating, and also eliminates the possibility that lawless people is opened door chain by outdoor application tool malice.
To achieve these goals, the technical solution that the utility model is taken is：A kind of door chain with magnet, including
Door and doorframe, further include chain part and locked groove part, the chain part is made of chain, fixed plate and lock, described solid
Fixed board is connect with doorframe, described chain one end and fixed plate ball-joint, other end and lock ball-joint, on the locked groove part
End and lower end are equipped with counter sink, and the locked groove part is fixedly connected by counter sink with door, the locked groove part by locked groove ontology,
Lock tongue, push rod and magnet composition, the lock tongue are hinged with locked groove body interior by axis pin, and the push rod connects with locked groove ontology
It connects, the magnet is fixedly connected with locked groove body interior.
Preferably, the lock is made of connector, sliding pin and cylinder closing piece, and the connector is connect with chain, described
Sliding pin is connect with connector, and the cylinder closing piece is connect with sliding pin.
Preferably, the locked groove ontology is equipped with outer groove and inside groove, and the outer groove upper end is equipped with access aperture.
Preferably, the diameter of section of the sliding pin is less than the width of outer groove, makes sliding pin that can smoothly be slided in outer groove, described
The diameter of section of cylinder closing piece is less than the width of inside groove, makes cylinder closing piece that can smoothly be slided in inside groove.
It is using the advantageous effect of above technical scheme：This carry magnet door chain, by the cylinder closing piece on lock from
Access aperture is inserted into locked groove ontology, because the diameter of section of the sliding pin is less than the width of outer groove, makes sliding pin suitable in outer groove
Profit is slided, and the diameter of section of the cylinder closing piece is less than the width of inside groove, makes cylinder closing piece that can smoothly be slided in inside groove, so
Sliding pin on lock slide downward in outer groove under the effect of gravity, cylinder closing piece on the lock slide downward in interior slot,
During cylinder closing piece moves downward, until the bottom for lock tongue being strutted and then being moved to inside groove, then in the effect of magnet
It is lower that lock tongue is tightly sucked, as long as indoor personnel, not downwards by lower push-rod, the cylinder closing piece of lock is constantly in by bolt lock
State only, no matter how chain vibrates or someone is stirring lock by tool outdoors, cannot all open door, improves
The stability of door chain locking avoids and protects failure caused by chain vibrates, and also eliminate lawless people is made by outdoor
The possibility of door chain is opened with tool malice；When opening door chain, first by lower push-rod, lock tongue is made to be close to the bottom end of inside groove, so
Afterwards by lock upward sliding until being taken out after access aperture.

Specific embodiment
Below against attached drawing, by the description of the embodiment, making to specific embodiment of the present utility model further detailed
Thin explanation, it is therefore an objective to help those skilled in the art have to the design of the utility model, technical solution it is more complete, accurate and
Deep understanding, and contribute to its implementation.
As shown in Figures 1 to 6, the utility model is a kind of door chain with magnet, improves the steady of door chain locking
It is qualitative, it avoids and protects failure caused by chain vibrates, it is anti-by outdoor application tool malice opening to also eliminate lawless people
Steal the possibility of chain.
Specifically, as shown in Figures 1 to 6, including door and doorframe, as shown in Figure 3, Figure 4,1 He of chain part is further included
Locked groove part 2, the chain part 1 12 are made of chain 10, fixed plate 11 and lock, as shown in fig. 6, the fixed plate 11 with
Doorframe connects, described 10 one end of chain and 11 ball-joint of fixed plate, other end and 12 ball-joints of lock, as shown in Figure 4, Figure 5,
2 top and bottom of locked groove part are equipped with counter sink 20, as shown in fig. 6, the locked groove part 2 is consolidated by counter sink 20 with door
Fixed connection, the locked groove part 2 are made of locked groove ontology 21, lock tongue 22, push rod 23 and magnet 24, the lock tongue 22 and locked groove sheet
It is hinged inside body 21 by axis pin, the push rod 23 is connect with locked groove ontology 21, and the magnet 24 and 21 inside of locked groove ontology are solid
Fixed connection.
As shown in figure 3, the lock 12 is made of connector 12-1, sliding pin 12-2 and cylinder closing piece 12-3, the connection
Body 12-1 is connect with chain 10, and the sliding pin 12-2 is connect with connector 12-1, and the cylinder closing piece 12-3 and sliding pin 12-2 connects
It connects.
As shown in Figure 4, Figure 5, the locked groove ontology 21 is equipped with outer groove 21-1 and inside groove 21-2, the outer groove 21-1 upper ends
Equipped with access aperture 21-11.
The diameter of section of the sliding pin 12-2 is less than the width of outer groove 21-1, makes sliding pin 12-2 can be in outer groove 21-1 smoothly
It slides, the diameter of section of the cylinder closing piece 12-3 is less than the width of inside groove 21-2, makes cylinder closing piece 12-3 can be in inside groove 21-2
In smoothly slide.
Specific working mode is illustrated with specific embodiment below：
