Description
Technical field
The utility model relates to door latch structure field more particularly to a kind of link locks.
Background technique
Gate lock for cabinet is frequently with the mode of intermediate locking, and both the fastening point between cabinet and cabinet door was located in the middle part of cabinet door, this
The design of sample cause cabinet door upper and lower ends can not locking, cabinet door is easily opened under external force.There is use in the prior art
World bolt carrys out the upper and lower side of locking cabinet door, and for the world bolt that links, a linkage mechanism usually is arranged at the middle part of lock,
But there is following defects for such door lock: linkage mechanism internal structure is complicated, and installation, maintenance, replacement are required to spend more
Time, while this kind of door lock price is higher, has virtually drawn high the price of cabinet.
Utility model content
The purpose of this utility model is to provide a kind of structure is simple, the convenient link lock of installation, maintenance.
To achieve the goals above, the technical solution of the utility model is as follows:
A kind of link lock, including two connecting rods, are equipped with multiple connectors between two connecting rods, the both ends of connector respectively with
Two connecting rods are hinged, and the middle part of connector is equipped with fixation hole, are equipped with rotation axis in the fixation hole, and the two of one of rotation axis
End is respectively equipped with handle and limited block, the rotation of handle energy band follower link, and connector is equipped with lock tongue.
Further, there are two the connectors, two connectors are respectively arranged at the upper and lower ends of the connecting rod.
Further, the fixation hole is quadrangle.
Further, the fixation hole is hexagon.
Further, the fixation hole is triangle.
Further, the angle of the acute angle between the connector and lock tongue is between 30 ° ~ 45 °.
It is simple that the utility model has the advantage of structures, convenient to install and maintain, passes through handle rotating connector, that is, linkage
Other connector rotations, while because structure is simple, which can reduce the use cost of user.
Detailed description of the invention
Fig. 1 is the utility model structural map；
Fig. 2 is the internal structural map that link lock is connect with cabinet door in embodiment；
Fig. 3 is the external structure figure that link lock is connect with cabinet door in embodiment；
Label declaration
Connecting rod 1, connector 2, fixation hole 3, handle 4, cabinet door 5, lock tongue 6.
Specific embodiment
Present invention is further described in detail with reference to embodiments.
As shown in Figure 1, link lock in the present embodiment includes two connecting rods 1, set that there are two connectors between two connecting rods 1
2, two connectors 2 are respectively arranged at the upper and lower side of connecting rod 1, and the both ends of connector 2 are hinged with two connecting rods 1 respectively, pass through company
The rotation of fitting 2 is able to drive two connecting rods 1 and moves up and down.The middle part of connector 2 is equipped with fixation hole 3, the present embodiment fixation hole
3 be quadrangle, is equipped with rotation axis (not shown) in fixation hole 3, is all provided with positioned at the both ends of the rotation axis on 1 top of connecting rod limited
Position block (not shown), is respectively equipped with handle 4 and limited block positioned at the both ends of the rotation axis of 1 lower part of connecting rod, handle 4 can drive
Connector 2 rotates.Integrally formed lock tongue 6 is additionally provided on connector 2, the angle of acute angle is at 30 ° between lock tongue 6 and connector 2
To between 45 °, while to guarantee locking cabinet door, the moving distance of connecting rod 1 is minimum, keeps use process more convenient comfortable,
Preferably, the angle of the acute angle in the present embodiment between lock tongue 6 and connector 2 is 45 °.
The link lock is installed in cabinet door 5 in the present embodiment, as shown in Figures 2 and 3, the connection positioned at 1 upper end of connecting rod
Part 2 is connect with cabinet door 5 by the limited block at rotation axis both ends, and the connector 2 and cabinet door 5 positioned at 1 lower end of connecting rod are by turning
Limited block and handle 4 on moving axis connect, and rotation axis can be rotated relative to door body.
The present embodiment is as follows using principle: user's swing handle 4, and the rotation band follower link 2 of handle 4 rotates, connection
The rotation of part 2 is so that lock tongue 6 goes to setting position, thus locking cabinet door 5.The rotation of lower attachment 2 also drives simultaneously
Connecting rod 1 moves up and down, and the connector 2 that the movement synchronous belt of connecting rod 1 moves top rotates.
The utility model proposes connecting rod lock construction it is simple, it is easy for installation, while the upper and lower side of cabinet door 5 can be carried out again
Locking greatly facilitates the use and later period maintenance of client.
