Description
Technical field
The present invention relates to the technical field of lock, relate to a kind of novel cabinet door lock structure being applied in door in middle-placed switch cabinet specifically.
Background technology
In tradition middle-placed switch cabinet, door lock is all screw fastening substantially, and it is opened and need use private key, and the screw thread of screw fastening is longer and door-plate has 3 screw fastenings, opens a time that needs are longer, brings unnecessary trouble to user operation and maintenance.Because door operation in middle-placed switch cabinet is comparatively frequent, if door opens inconvenience, be just not easy to the operation operating and need emergent management normally, bring certain hidden danger also can to the use of equipment.
Summary of the invention
The invention provides a kind of novel structure attractive in appearance, open close convenient and swift, lock firm middle-placed switch cabinet cabinet door lock structure.
To achieve these goals, the technical scheme that the present invention takes is this cabinet door lock structure that provides, comprise the handle be arranged on door-plate, be provided with the upper drive rod and lower drive rod that are hinged in described handle, described upper drive rod and lower drive rod move with handle and synchronously move round about; Described upper drive rod connects the upper connecting rod rack upwards extended, and described lower drive rod connects the lower link support to downward-extension; The upper end of described upper connecting rod rack and the lower end of lower link support are all connected with door bolt, are that the doorcheek that described door bolt is corresponding is provided with the fixing guide that door bolt is fixed in grafting.
For making technique scheme more detailed and concrete, the present invention also provides following further optimal technical scheme, to obtain satisfied practical function:
The limiting bracket of the two relative position restricted is overlapped between described upper connecting rod rack and lower link support.
Be matched in clearance between described limiting bracket and described upper connecting rod rack and lower link support.
Connection spaced apart two door bolts on described lower link support, one of them is located at lower link support bottom.
On described door bolt, all cover has the fairlead be fixed on door-plate.
The below of described handle is provided with the lockhole controlling the activity of described handle or locking.
The present invention compared with prior art, a kind of novel cabinet door lock structure is provided, this cabinet door lock structure, upper and lower strut support is connected to door bolt, moved the motion controlling upper and lower strut support by pull handle, drive door bolt is fixed in the fixing guide on grafting and doorframe and is opened cabinet door to reach locking effect or to shift out guide.Cabinet door lock structure of the present invention is simple, open close convenient and swift, be applied in can be firm on middle-placed switch cabinet locking cabinet door, open cabinet door fast, there is stronger practicality.

Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail.
Cabinet door lock structure of the present invention, as shown in Figure 1, 2, comprises the handle 1 be arranged on door-plate 10, is provided with the upper drive rod 3 and lower drive rod 4 that are hinged in handle 1, and upper drive rod 3 and lower drive rod 4 move with handle 1 and synchronously move round about; Upper drive rod 3 connects the upper connecting rod rack 5 upwards extended, and lower drive rod 4 connects the lower link support 6 to downward-extension; The upper end of upper connecting rod rack 5 and the lower end of lower link support 6 all connect door bolt 7, and the doorcheek in door bolt 7 correspondence is provided with the fixing guide 11 that door bolt 7 is fixed in grafting.Fig. 4 is the schematic diagram that this cabinet door lock structure is applied on door-plate 10, the upper and lower drive rod similar of this novel cabinet door lock is in the articulated structure of scissors, by the bolt connecting rod impetus be connected, realization is when upwardly handle 1, the bolt inside established drives upper drive rod 3 and lower drive rod 4 respectively to upper and move down, and is plugged on respectively and is positioned at the upper and lower fixing guide 11 of doorcheek, realize the locking of door-plate 10, wherein fix guide 11 structure as shown in Figure 3, be provided with fixed pin holes.
In the present invention, overlap the limiting bracket 9 of the two relative position restricted between upper connecting rod rack 5 and lower link support 6, both guarantees position is accurate, promotes certain distance and synchronously can realize locking or open.Be matched in clearance between limiting bracket 9 and upper connecting rod rack 5 and lower link support 6.This matched in clearance should select appropriate size, can not be excessive or too small.The phenomenon blocked because being subject to force unbalance when upper connecting rod rack 5 and lower link support 6 appear in motion when excesssive gap; Easily occur because of activity space problem when gap is too small that motion is not smooth, thus cause door-plate 10 be difficult to locking or open.
Cabinet door lock of the present invention, preferably, early spaced apartly on lower link support 6 be provided with two door bolts 7, one of them is located at lower link support 6 bottom, another is connected to the top of lower end door bolt 7 by connection bracket, is also provided with fixing guide 11 on the doorframe of correspondence position simultaneously.The door bolt 7 of this two door bolts 6 and upper connecting rod rack 5 upper end with the use of, realize upper, middle and lower three-point fix, structural stability when ensureing locking, more solid and reliable.Wherein on each door bolt 7, all cover has fairlead 8, and fairlead 8 is fixed on door-plate 10, and upper and lower strut support drives each door bolt 7 to move up and down in fairlead 8, avoids moving off-line, ensures that door bolt 7 moves grafting accurately with in corresponding fixing guide 11.
The present invention is provided with the lockhole 2 of control handle 1 activity or locking in the below of handle 1, have general lock core junction structure, by using matched key rotational lock core, realizing blocking locking handle 1, namely cannot promote handle 1 and move up and down; Or release handle 1, make it can move up and down opening or locking with switch board door.
Cabinet door lock structure of the present invention, upper and lower strut support is connected to door bolt 7, moved the motion controlling upper and lower strut support by pull handle 1, drive door bolt 7 is fixed in the fixing guide 11 on grafting and doorframe and is opened cabinet door to reach locking effect or to shift out guide 11.Cabinet door lock structure of the present invention is simple, open close convenient and swift, be applied in can be firm on middle-placed switch cabinet locking cabinet door, open cabinet door fast, there is stronger practicality.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of various unsubstantialities that method of the present invention design and technical scheme carry out or directly apply to other occasion, all drop within protection scope of the present invention.
