Abstract
The invention relates to a locking device for a plug box, which belongs to the technical field of power supply facilities. The device comprises a rectangular box cover with two opposite locking edges, a lock head mounted in the geometric centre of the rectangular box cover, and four locking pins respectively hinged in the positions near the two opposite locking edges of the rectangular box cover in pairs, wherein adjacent ends of two paired locking pins of each locking edge are mutually overlapped at the middle part of each locking edge, and the overlapped sections are respectively provided with slotted holes extending in the length direction; and a rotating lock core is mounted in the lock head, the inner end of the rotating lock core extends out of a lock tongue towards two sides respectively, the outer end of the lock tongue on the two sides is respectively hinged with one ends of two connecting rods extending to the two locking edges, and the other ends of the two connecting rods form sliding pairs with the slotted holes of the overlapped sections of the two pairs of locking pins respectively. With the adoption of the locking device, linkage between the lock core and the locking pins of the plug box can be realized through very convenient control in a very simple structure, as a result, the purpose of closing and locking a box door or opening the box door is achieved, and the original cumbersome process of dismounting self-tapping screws is avoided.
Description
Technical field
The present invention relates to a kind of locking device of casing, especially a kind of jack box locking device, belongs to power supply facilities technical field.
Background technology
Jack box is the conventional facility that power supply buses groove patches, and during grafting operation, needs chamber door to take off, after grafting, needs covered by chamber door and reliably locked by simple motion.The grafting chamber door that applicant adopted in the past installs self-tapping screw locking by four corners, and lock chamber door first will install four self-tapping screws, then locks with key.Open chamber door and then will lay down four self-tapping screws, very inconvenient.
Retrieval find, application number be 89219839.7 Chinese patent disclose the door lock that a kind of security door uses, it mainly comprises detent mechanism, door lock mechanism and installing plate.Detent mechanism and door lock mechanism are installed on a mounting board, and detent mechanism is made up of lock core and lock core box, and door lock mechanism is made up of the rotating disk, alignment pin, pull bar, latch etc. forming slider-crank mechanism.Detent mechanism is in order to limit the position of rotating disk, and door lock mechanism is used for controlling the anglec of rotation of rotating disk.In addition, application number be 200620110999.6 Chinese patent disclose a kind of self-locking electric control burglar-proof door, its mechanical linkage part be adopt lever principle, the length of power arm is more greater than resistance arm, and its motor drive mechanism is more laborsaving; It mainly forms: the supporting of drive link, turning cylinder, chute, pusher arms, elongated hole push rod, roller, armature, electromagnet, armature elongated hole arm-tie, fixed leg, pedal arm, pedal, pedal arm, pedal arm extension spring, sliding sleeve, pull bar, boss, bayonet socket, return spring, convex guide peg, back-moving spring.The equal complex structure of above-mentioned door lock mechanism, is therefore difficult to improvement and design and is transplanted to jack box.
Summary of the invention
The object of the invention is to: propose one and reliably can lock sealed while and the simple as far as possible jack box locking device of structure.
In order to reach above object, jack box locking device of the present invention comprises the rectangle case lid with two relatively sealed limits, the tapered end being contained in rectangle case lid geometric center, and paired hinged four lock pin near the relatively sealed limit of rectangle case lid two respectively; Paired two, the sealed limit of every bar lock pin abutting ends are superimposed with each other in the middle part of described sealed limit, and superimposed section is shaped with the long slot bore extended along its length respectively; Described tapered end is built with rotary locking cylinder, dead bolt is extended respectively to both sides in the inner of described rotary locking cylinder, the dead bolt outer end of both sides is hinged with the one end of two connecting rods extended towards two sealed limits respectively, and the other end of two connecting rods forms moving sets with two to the long slot bore locking superimposed section of pin respectively.
After case lid buckle closure is on jack box, when twisting lock core with key, the connecting rod of both sides can be affected respectively by the dead bolt at two ends, thus drive two to the transposition between locking and lockset position of coupler of lock pin.When going to locked position, the outer end of lock pin will in the flange of wedging jack box mouth, thus by sealed to case lid and casing, and when going to lockset position of coupler, the outer end of locking pin will be left in the flange of jack box mouth, thus case lid can be separated with casing.
The present invention further improves: described in pairs two lock pin away from end, there is elbow respectively that extend to residing sealed limit, therefore sealed more reliable.Described two is symmetrical about the geometric center of case lid to lock pin.Sealed manipulation can be made so more reliable and stable.The one side that the elbow of described lock pin presses close to case lid has the wedging inclined-plane eliminating locking gap.It is hereby ensured that the jack box of locked state closes, avoid case lid to loosen.
Adopt after the present invention, the interlock between jack box lock core and lock pin can be realized with very simple and direct structure and manipulation very easily, thus reach sealed and lock chamber door or open the object of chamber door, avoid the complicated processes of original unloading self-tapping screw.

Detailed description of the invention
Embodiment one
As shown in Figure 1, Figure 2, Figure 3, Figure 4, the long limit of rectangle case lid 1e is two relatively sealed limits to the jack box locking device of the present embodiment, and the geometric center of rectangle case lid 1e diagonal point of intersection is equipped with tapered end 1a.Four lock pin 1d are hinged near two relatively sealed limits of rectangle case lid in pairs respectively by riveting pin O.Two couples of lock pin 1d are symmetrical about the geometric center of case lid.Two lock pin 1d abutting ends on the sealed limit of every bar are superimposed with each other in the middle part of sealed limit, and superimposed section is shaped with the long slot bore extended along its length respectively.Two paired lock pin 1 away from end, there is elbow respectively that extend to sealed limit.The one side that the elbow of lock pin 1d presses close to case lid has the wedging inclined-plane (not shown) eliminating locking gap.Tapered end 1a is built with rotary locking cylinder, dead bolt 1b is extended respectively to both sides in the inner of rotary locking cylinder, the dead bolt 1b outer end of both sides is hinged with the inner of the two connecting rod 1c extended towards two sealed limits respectively, and the outer end of two connecting rod 1c forms moving sets with two to the long slot bore locking superimposed section of pin respectively.
As shown in Figure 1, after case lid 1e buckle closure is on jack box, when twisting lock core 1a with key, the connecting rod 1c of both sides can be affected respectively by the dead bolt 1b at two ends, thus drive two to lock pin 1d transposition between locking and lockset position of coupler.When as shown in Figures 2 and 3, when going to lockset position of coupler, the elbow of lock pin 1d will leave in the flange of jack box mouth, thus make case lid 1e can as required with casing delamination, to carry out the grafting operation in case.When going to locked position as shown in Figure 4, the elbow of lock pin 1d in the flange of the corresponding box cover lock pilled-in selvedge of wedging jack box mouth, and under the effect on wedging inclined-plane, by closely sealed to case lid and casing, thus will guarantee that the grafting in case is not subject to external interference.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of application claims.
