Description
Technical field
The utility model relates to a kind of locking device, and the locking device that is connected between particularly a kind of cabinet door that is used for the power transmission and distribution a complete set of equipment and the cabinet belongs to the technical field of switchboard accessory.
Background technology
Switchboard is an equipment for power transmission and distribution, and therefore, its safety is very important.In order to guarantee the security performance of switchboard, can between the cabinet door of switchboard and cabinet, a locking device be set usually.This locking device is the key connection locking device of " resistance short circuit arcing fault " usefulness in the complete switch equipment, power transmission and distribution a complete set of equipment particularly rated voltage surpasses the high-voltage web system of 3KV, the transient energy of its device interior short trouble electric arc is very big, if the design of locking device is unreasonable, when short circuit arcing fault takes place, can cause equipment explosion, door lock comes off, parts fly, damage equipment, even threat personal safety, therefore, the quality of locking device, the quality of mechanical performance, structure rationally, be directly connected to complete switch equipment reliability of operation and safety.
At present, the locking device in the complete switch equipment, mainly adopt three kinds of modes: the one, the locking device of screw thread fastening type is generally used screw thread fastening type in the high-voltage board.The quality of screw thread fastening type is put to death in the final precision of screw thread, and it comprises that selection, the crudy of material and heat treatment mode, the cooperation of screw thread etc. are all multifactor, very easily sliding tooth or dropout; Simultaneously, it is that point type is stressed, yielding the coming off in cabinet riveting nut place; Therefore screw thread fastening type locking is extremely unreliable.The 2nd, dead bolt is taken the locking device of lobe formula, and it is a kind of semi girder force structure that dead bolt is taken the lobe formula, relies on the anti-bending strength of sheet dead bolt fully, ability, and the locking that should not be used for the product high-tension cell connects; Three is locking devices of four connecting rod coordinated types, but connecting rod coordinated type design principle more complicated, and the reliability of locking is relatively poor.
The content of utility model
The cabinet door lock that technical problem to be solved in the utility model provides a kind of switchboard tightly installs, the locking device good rigidly of this switchboard, strong, the reliable lock, easy and simple to handle and simple and reasonable for structure of shear resistance, and the safety that has improved switchboard greatly.
In order to solve the problems of the technologies described above, the cabinet door lock of a kind of switchboard of the utility model tightly installs, comprise the locking plate that the pull bar that is fixedly installed on described cabinet door inboard, some locking bars, an interlock part, guide-localization prop up part, adapt with locking bar, the outer edge that described guide-localization props up part and cabinet door is provided with respectively and described locking bar respective connecting and lockhole, described locking plate is fixedly installed on the cabinet inboard of described switchboard, described some locking bars are horizontally through described interlock respectively and prop up part, and prop up part with described interlock and fixedly connected and be integral; Every described locking bar one end is mobilizable to be inserted in described guide-localization and to prop up in the connecting hole of part, and is positioned at an end of corresponding lockhole; In the mobilizable fairlead that is inserted on the described door of switch cabinet of the other end, described guide-localization props up vertical being fixedly installed on the described door of switch cabinet of part, described pull bar is horizontally installed on described interlock and props up between the door lock of part and described switchboard, and described pull bar two ends are propped up part with the door lock of described switchboard and described interlock respectively and fixedlyed connected; During connection, every described locking bar one end all passes corresponding described connecting hole, corresponding described locking plate and cabinet corresponding lockhole on the edge outdoors.
The cabinet door lock of above-mentioned a kind of switchboard tightly installs, and wherein, described locking bar props up part with described interlock fixedlys connected by corresponding positioning sleeve respectively.
The utility model can be realized following beneficial effect:
When 1, working, the door lock of rotating switch cabinet, the pulling pull bar drives an interlock part by pull bar, an interlock part pulling locking bar motion, make locking bar pass connecting hole, locking plate and the cabinet lockhole on the edge outdoors, realize the latch between cabinet door and cabinet, making the stress model of switchboard is the simply supported beam mode, thus improved locking device shear resistance, make the connection of locking device more reliable, and it is easy and simple to handle, simple and reasonable for structure; In addition, when short trouble takes place,, thereby improved the ability that switchboard is resisted arc energy, guaranteed that door lock assembly is indeformable, improved the safety of switchboard greatly because locking bar is the latch between cabinet door and cabinet.
2, described locking bar props up part with described interlock and fixedlys connected by positioning sleeve, and therefore, the utility model loading and unloading are more convenient.
