Abstract
The utility model relates to a self-locking device for a cabinet door. The self-locking device comprises a lock seat, wherein the front end of the lock seat is fixed on a door frame; the tail end of the lock seat penetrates through a lock hole in a door leaf; a lock sheet with the width which is less than the diameter of the lock hole is mounted at the tail end of the lock seat; the lock sheet rotates and slides around the tail end of the lock seat by rotating a sliding mechanism to be clamped at the outer end of the lock hole. The self-locking device for the cabinet door can be used for doors of electric locomotive equipment cabinets and the like, and other tools such as keys are not needed; the door leaf is locked by the structure of the self-locking device; the self-locking device for the cabinet door is simple to operate, reliable in structure and low in cost.
Description
Technical field
The utility model relates to a kind of cabinet door self-locking device.
Background technology
Existing cabinet door self-locking device is of a great variety, mostly adopts the structure of similar keeper, complex structure, and use cost is higher.
Summary of the invention
The purpose of this utility model is, for the deficiencies in the prior art, provides a kind of cabinet door self-locking device, and simple in structure, easy to operate, cost is low.
The technical solution of the utility model is, a kind of cabinet door self-locking device, comprise that front end is fixed on the lock on doorframe, the end of described lock is through the lockhole on door leaf, described lock end is installed the locking plate that width is less than lockhole diameter, and this locking plate is clamped on lockhole outer end by rotational slide mechanism around the rotation of lock end, slip.
The width of locking plate is less than lockhole diameter, can guarantee that locking plate passes lockhole, door leaf smooth opening.The rotational slide mechanism after image keeper that locking plate can be rotated to an angle equally slides, and then is clamped on lockhole outer end, without aids such as any keys, and can be by door leaf self-locking.
Described rotational slide mechanism comprise along the length direction of lock be located at lock end mounting groove, along locking plate length direction, be located at the guide groove of the inclination on the plate face of locking plate, and be provided with connecting pin through guide groove and locking plate being hinged in the mounting groove of lock, locking plate can around connecting pin rotate and in lockhole axially parallel or plumbness.
Guide groove can rotate and also can slide along pin around lock connecting pin, and the guide groove that locking plate tilts makes locking plate rotate into after vertical state the spacing of locking plate and lock in moving process downward or upward to diminish gradually, thereby door leaf is pressed on lock.
When released state, in line, the lockhole on door leaf can be thrown off from lock for locking plate and lock, and door leaf can be opened.
When locking state, locking plate becomes plumbness with lock, locking plate is stuck in outside door leaf lockhole, door leaf cannot be opened, in addition the inclined guide groove of locking plate make locking plate upper move or folding process in door leaf is locked, the gradient of inclined guide groove determines according to the friction factor of material and the downward gravity of locking plate self, and locking plate cannot unclamp automatically, makes door leaf locking reliable and stable.
The width of described locking plate is consistent with the diameter of lock or width.
The gradient of described guide groove refers to guide groove length direction and locking plate length direction angle, according to material friction coefficient and the downward gravity of locking plate self, determines, and be 3 ° ~ 30 °.
The utility model, as a kind of cabinet door self-locking device, can be used for, in the cabinet doors such as electric locomotive equipment cabinet, without other instruments such as keys, by self structure, door leaf to be locked, and simple to operate, reliable in structure, and cost is lower.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of cabinet door self-locking device described in the utility model;
Fig. 2 is the structural representation of self-locking device released state in Fig. 1 embodiment;
Fig. 3 is the schematic diagram of self-locking device locking state in Fig. 1 embodiment.
The specific embodiment
As shown in Figure 1, a kind of cabinet door self-locking device, comprise that front end is fixed on the lock 3 on doorframe 5, the end of lock 3 is through the lockhole 6 on door leaf 4, lock 3 ends are installed the locking plate 1 that width is less than lockhole 6 diameters, the width of locking plate 1 is consistent with the diameter of lock 3, this locking plate 1 by rotational slide mechanism around lock 3 ends rotations and in lockhole 6 axially parallels or plumbness.
Rotational slide mechanism comprise along the length direction of lock be located at lock 3 ends mounting groove 7, along locking plate 1 length direction, be located at the guide groove 8 that the plate face of locking plate 1 tilts, the gradient of guide groove 8 is 10 °, and be provided with connecting pin 2 through guide groove 8 and locking plate 1 be hinged in the mounting groove 7 of lock 3, locking plate 1 can slide at guide groove 8 around connecting pin 2 rotations and described connecting pin 2.
This self-locking device released state as shown in Figure 2, by locking plate 1 rotation, makes itself and lock 3 in alignment, and the lockhole 6 on door leaf 4 can be from lock 3 disengagements, and door leaf 4 can be opened.
This self-locking device locking state as shown in Figure 3,3 one-tenth plumbness of locking plate 1 and lock, locking plate 1 is stuck in outside lockhole 6, and door leaf 4 cannot be opened, in addition the inclined guide groove 8 of locking plate 1 make locking plate 1 upper move or folding process in door leaf is locked.
If guide groove 8, as the incline direction in the present embodiment, rotates up locking plate 1 when locking, and down sliding locking plate 1; If the mounting groove 7 on lock 3 is around lock 3 central axis half-twists, the inclined guide groove 8 of locking plate 1 is locked door leaf locking plate 1 in moving left and right process.
