Description
Technical Field
The invention relates to a locking device, in particular to a cabinet door locking device, and belongs to the technical field of cabinet sealing.
Background
In the existing cabinet door lock, most door locks can only realize one-point locking, which is not beneficial to electromagnetic shielding of a cabinet, and the shielding and sealing materials cannot be compressed because of one-point locking of the door locks, and the unlocking handle of the door lock cannot be locked, so that the situation of locking failure can occur.
Disclosure of Invention
In order to overcome the defects in the prior art, the invention aims to provide the locking device which can realize multi-point linkage and effectively close the cabinet door of the cabinet.
In order to achieve the above object, the present invention adopts the following technical solutions:
a locking device comprises a connecting rod, a bolt and a rack;
the lock tongue is fixed at one end of the rotating shaft, and a gear is arranged at the other end of the rotating shaft;
one side of the connecting rod is provided with a plurality of shaft sleeves,
the shaft sleeve is matched with the rotating shaft, and the gear is arranged in the shaft sleeve cavity;
any rotating shaft is rotated by a coaxial handle arranged on the other side of the connecting rod and linked with the lock tongue through a rack in tooth joint with the gear.
The locking device further comprises a pair of closing magnetic strips; are respectively arranged at the inner side of the handle and at the corresponding angle position on the connecting rod when the lock tongue is locked.
The locking device is applied to a cabinet door, and the cabinet door is provided with a sliding groove for accommodating a rack;
and the door pocket matched with the cabinet door is provided with a lock hole matched with the lock tongue.
Further, the quantity of above-mentioned spring bolt is 3, lays respectively in the top, the bottom and the middle part of rack door.
Furthermore, the handle is fixed with the rotating shaft through a hinge shaft.
Still further, when the spring bolt locks, the corresponding angular position of above-mentioned cabinet door is equipped with the draw-in groove that matches the handle, and, the closed magnetic stripe that corresponds locates in the draw-in groove.
The invention has the advantages that:
according to the locking device, a multi-point linkage locking mode is realized through the sliding rack; the handle can be flexibly rotated in a hinged mode, and meanwhile, the handle can be placed in the clamping groove by using a hinged point base point; through the adsorption of closed magnetic stripe, can further lock the handle, prevent the not hard up condition after locking. The cabinet door locking device is simple in structure, convenient to use, convenient to disassemble, assemble and maintain, capable of effectively solving the problems of sealing and shielding of the cabinet door, capable of guaranteeing the locking state of the cabinet door, and strong in practicability and wide in applicability.

Detailed Description
The invention is described in detail below with reference to the figures and the embodiments.
A locking device is composed of a connecting rod 1, 3 lock tongues 3, 1 rack and a handle 2.
The bolt 3 is fixed at one end of the rotating shaft 4, and the other end of the rotating shaft 4 is fixed with the gear 6;
one side of the connecting rod 1 is provided with 3 shaft sleeves 5 which are matched with the rotating shaft 4 at the upper end, the middle part and the lower end respectively, and the gear 6 is arranged in the cavity of the shaft sleeve 5.
Through connecting rod 1, this locking device is fixed in the door side of rack door, and in the opposite side of connecting rod 1, handle 2 is in the outside of rack door, and is coaxial fixed with pivot 4 of middle part spring bolt 3 to through articulated mode and hub connection, the luffing motion of being convenient for.
The door side of the cabinet door is provided with a sliding groove for accommodating the rack.
The handle 2 is rotated, the gear 6 is communicated with the rack to slide up and down along the sliding groove, and then the gears 6 at the upper end and the lower end are linked, namely the lock tongues 3 at the upper end and the lower end are linked to rotate, and the locking action is completed in cooperation with the lock holes in the door sleeve.
A clamping groove matched with the handle 2 is also arranged at the corner position locked by the lock tongue 3 and on the outer side of the cabinet door; a closed magnetic strip 7 is arranged in the clamping groove and corresponds to the closed magnetic strip 7 on the inner side surface of the handle.
When locking a door, the cabinet door is tightly attached to the door sleeve, the handle 2 is rotated to complete the locking action of the bolt 3, the handle 2 is turned downwards and fixed in the clamping groove, and the closed magnetic stripe 7 is further used for adsorption and fixation. The door is opened and the reverse action is performed.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by using equivalent alternatives or equivalent variations fall within the scope of the present invention.
