Abstract
The utility model discloses a connecting rod gate lock for a novel plate-type electric-energy metering control box. The connecting rod gate lock overcomes the problem that a gate is not locked completely or cannot be opened due to the fact that a metal material in a connecting rod lock is rusted easily and poor connection occurs between moving parts in the prior art. The connecting rod gate lock comprises a lock cylinder, an elliptical cam cover, a bolt, an upper connecting rod and a lower connecting rod, wherein a concentric gasket is arranged at a central point of the cam cover; a key and a key groove that are matched with each other are arranged on and formed in the gasket and a lock shaft of the lock cylinder respectively; two elliptical arc cam grooves distributed antisymmetrically are formed in the cam cover in a circumferential direction; columnar bosses at one end of the upper connecting rod and one end of the lower connecting rod can slide in the elliptical arc cam grooves; the upper connecting rod is symmetrical to the lower connecting rod by taking the lock cylinder as a middle point; a first fixing mechanism and a second fixing mechanism are arranged at the other ends of the upper connecting rod and the lower connecting rod; and the upper connecting rod and the lower connecting rod are provided with at least one guide groove and one guide cover plate. The connecting rod gate lock is simple in structure, and easy to fabricate, and as the connecting rod gate lock is made of a non-metal material, the connecting rod gate lock can be fabricated in a large scale by molds.
Description
Technical field
The utility model relates to a kind of locking device, particularly relates to a kind of connecting rod door lock for New-type plate electric energy metrical control cabinet.
Background technology
Chinese patent application numbers 201120374891.9, open day on 07 04th, 2012, the utility model name is called rotary connecting rod lock, and this application discloses and a kind ofly can make straight up and down vertical motion of connecting rod, and can stop descending link lock after the gag lever post that arranges to the lock core under connecting rod.Its weak point is: outdoor permanent use, corrosion easily occurs in the swing type connecting rod of metal material, can cause that kinematic accuracy is poor, frictional resistance is large, connectivity problem occurs between lock core, drive link and lock frame, the phenomenon of not exclusively locking a door and opening the door might occur.The utility model adopts nonmetals such as strengthening nylon or SMC, provides transformable radius of gyration with the oval cam lid, realizes moving both vertically of upper and lower strut.
Summary of the invention
The utility model has overcome in prior art, because corrosion easily occurs in metal material in link lock, between lock core, drive link and lock frame, connectivity problem appears, cause occurring not exclusively locking a door and the do not open shortcoming of door, provide a kind of simple in structure, be easy to make and the connecting rod door lock of New-type plate electric energy metrical control cabinet easy to use.
Technical solution of the present utility model is, a kind of connecting rod door lock for New-type plate electric energy metrical control cabinet is provided, contain lock core, transmission mechanism, dead bolt and upper connecting rod, lower link, its transmission mechanism is an oval cam lid, the oval arc-shaped cam path that two antisymmetry distribute is contained along circumferential direction in camb cap inside, the structure that one section approximate " Z " font is respectively arranged on upper connecting rod, lower link, one end has the ellipse arc cam path coupling on cylindrical boss and camb cap, and cylindrical boss can be slided in the oval arc-shaped cam path.The central spot of camb cap has a concentric pad, is respectively equipped with key and the keyway of mutual coupling on the lock shaft of pad and lock core, and an end of lock shaft is provided with screw thread, can camb cap be fixed on lock shaft attaching nut.Upper connecting rod, lower link are symmetrical structure take lock core as mid point, and the other end has the first fixed mechanism, the second fixed mechanism.Have separately a gathering sill and defelctor apron on it at least.
Compared with prior art, the door using lever as hinge axle lock of the board-like electric energy metrical control cabinet of the utility model has the following advantages: adopt the nonmetals such as fiber reinforced nylon or SMC, provide transformable radius of gyration with the oval cam lid, realize moving both vertically of connecting rod, lower link, can outdoor permanent use, kinematic accuracy is high, frictional resistance is little, can not occur connectivity problem occurring between lock core, camb cap and upper connecting rod, lower link, and cause the phenomenon of not exclusively locking a door and opening the door.
Description of drawings
Fig. 1 is a kind of structural representation of the connecting rod door lock for the New-type plate measurement control box;
Fig. 2 is a kind of partial enlarged drawing of the door using lever as hinge axle lock construction schematic diagram for the New-type plate measurement control box;
Fig. 3 is a kind of rear elevation of structural representation convexity wheel cap of the connecting rod door lock for the New-type plate measurement control box.
The specific embodiment
One of structural representation: in description of drawings, label 1 ˊ is that the first fixed mechanism, 1 is the second fixed mechanism, the 2nd, and defelctor apron, 3 ˊ are upper connecting rods, the 3rd, lower link, the 4th, gathering sill, the 5th, cylindrical boss, the 6th, oval cam lid, the 7th, lock core.
Three of structural representation: in description of drawings, label 8 is dead bolts, the 9th, and ellipse arc cam path, pad 10.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail: when opening, key is inserted core 7, the clockwise direction rotation, transmission mechanism oval cam lid 6 with its concentric pad 10 on the effect of key under, synchronously turn clockwise with the core 7 that has keyway, in dead bolt 8 on oval cam lid 6 will be retracted door-plate at this moment, first lock untied.
Because upper connecting rod 3 ˊ, lower link 3 are symmetrical structure take lock core as mid point, the other end has the first fixed mechanism, the second fixed mechanism.It has a restriction in vertical direction separately at least, and it does straight-line gathering sill and defelctor apron.The oval arc-shaped cam path 9 that two antisymmetry distribute is contained along circumferential direction in oval cam lid 6 inside, particularity due to the camb cap structure, in rotation, in vertical direction radius is gradually from large to small, when the ellipse arc cam path 9 of the cylindrical boss 5 that causes connecting rod 3 ˊ, lower link 3 one ends on camb cap 6 slides, upper connecting rod 3 ˊ, lower link 3 in vertical direction total length from large to small, thereby realize that second and third some lock unties.
During door close, counterclockwise rotation, a whole course of action and opposite when opening, camb cap 6 synchronously is being rotated counterclockwise with core 7, and the dead bolt 8 on this moment oval cam lid 6 will stretch out outside door-plate, first lock locking.Particularity due to the camb cap structure, when rotated, radius on vertical direction changes from small to big gradually, when the ellipse arc cam path 9 when cylindrical boss 5 on camb cap 6 slides, can cause connecting rod 3 ˊ, lower link 3 in vertical direction total length change from small to big, thereby realize second and third some lock locking.
