Abstract
The utility model relates to a shielding cabinet door locking mechanism which comprises a convex sheet, the convex sheet outwards bends from one side of a door frame, and the vertical surface of the convex sheet inclines towards the door frame at an angle of 15-20 degrees. Furthermore, the side corresponding to a shielding door is provided with a locking surface which inclines at the same side of the shielding door and is parallel to the shielding door in a closed state, and the locking surface is fixedly provided with a double-ended spring piece which tightly supports against the convex sheet of the door frame in the closed state of the shielding door. By adopting a single-side inclined locking way, the stress of the spring piece is reduced during the opening and the closing of the shielding door, and the shielding cabinet door locking mechanism has convenient and free operation, simple structure and long service life.
Description
Technical field
The utility model relates to a kind of tight mechanism of cabinet door lock of shielding cabinet.
Background technology
Electronic equipments such as some computer, the webserver, each communication of switch need move within the border at shading ring, prevent from that the said equipment is in operation to be subjected to the interference of external electromagnetic ripple or the leakage of confidential information, to guarantee its operate as normal; Shielding cabinet is widely used as a kind of shielding device light, flexible, easy to use.The cabinet door of shielding cabinet must have locking function preferably, at present, the cabinet door of shielding cabinet is many at the vertical outwards lug of bending of doorframe one side, the shield door respective side is provided with clip slot, the clip slot inwall is equipped with a pair of spring leaf, and at closing time, the lug of doorframe just in time inserts between a pair of spring leaf of shield door, clamped by spring leaf, thereby make cabinet door lock tight.The shortcoming of this retaining mechanism is that open and close Men Shixu is firmly bigger, wants moment to drag too hard even, and this can cause vibration, and the electronic equipment in the cabinet is had harmful effect, and in bigger stress lower spring easy deformation, shortens its application life.
Summary of the invention
The utility model provides a kind of switch door labour-saving tight mechanism of shielding cabinet door lock.
The tight mechanism of the utility model shielding cabinet door lock, the lug that comprises the outer bending of doorframe one side direction, said lug is tilted less than the angle of 30 degree to frame side by vertical plane, the shield door respective side is provided with to homonymy, and under the state of closing the door parallel with it locking face, be fixed with the duplex round reed on this locking face, spring leaf is tight against said doorframe lug under the shield door closed condition.
Said doorframe lug angle of inclination is preferably 15～20 degree.
The tight mechanism of the utility model shielding cabinet door lock was because the locking mode that adopts single face to tilt had both had the locking function of well closing the door, when making the open and close door again, the stress that spring leaf is subjected to reduces, and operates lightly, freely, and avoids the equipment vibrations impaired, simple in structure, prolong application life.

Fig. 2 is the A-A sectional view of shielding cabinet.
Fig. 3 is the B portion amplification assumption diagram of Fig. 2.
Fig. 4 is traditional shielding cabinet locking mechanism structure schematic diagram.
Fig. 1,1 is the shielding cabinet cabinet, and 2 is shield door, and 3 is doorframe, and 4 is the doorframe lug, and 5 is the locking face of shield door, and 6 is the duplex round reed.
The specific embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
Fig. 1 is a shielding cabinet, contains cabinet 1 and the shield door 2 made by cold-rolled steel sheet, and shield door 2 is connected by the doorframe of hinge with cabinet 1.
Be provided with the tight mechanism of cabinet door lock of the present utility model as Fig. 2 and 3 expression shielding cabinets, comprise the lug 4, shield door 2 locking faces 5 that parallel with lug 4 that be provided with that stretch out and bend by doorframe 3, this lug 4 and locking face 5 all form the angle [alpha] of spending less than 30 with vertical guide, and this angle [alpha] is good at 15～20 degree; By screw duplex round reed 6 is arranged on locking face, at closing time, lug 4 is tight against and compresses spring leaf 6, with shield door 2 lockings.
Fig. 4 represents that the lug 4 of traditional shielding cabinet retaining mechanism and doorframe 3 angles are the right angle, and shield door 2 is provided with two locking faces 5, two locking faces 5 parallel with lug 4 spring leaf 6 is housed respectively.Close the door under the state, lug 4 inserts between two locking faces 5, and spring leaf 6 is clamped lug 4.The locking mechanism that single face of the present utility model tilts is compared with this two-sided right angle locking mechanism, and the stress that spring leaf is subjected to reduces, and operates light, freely.
Claims (2)
1, the tight mechanism of shielding cabinet door lock, the lug that comprises the outer bending of doorframe one side direction, said lug is tilted less than the angle of 30 degree to frame side by vertical plane, the respective side of shield door is provided with to homonymy, and under the state of closing the door parallel with it locking face, be fixed with the duplex round reed on this locking face, spring leaf is tight against said doorframe lug under the shield door closed condition.
2, the tight mechanism of shielding cabinet door lock according to claim 1 is characterized in that said lug angle of inclination is 15～20 degree.
