Description
Technical field
The utility model relates to a kind of latch mechanism, particularly relates to a kind of latch mechanism for aerial conductor fault indicator.
Background technology
In distribution pole line system, line construction is complicated.For the unimpeded normal operation of maintenance line, in time find the fault that occurs on circuit, can on-call maintenance, in time eradicate fault, fault detector (or claiming fault alarm) is installed in the security of system that restores electricity operation on pole line.Fault detector can be located the trouble spot rapidly.Can accomplish in time to fix a breakdown for this reason, the normal operation of the system that restores electricity.But, be placed in fault detector between current sensor on pole line and pole line usually because when operation, be subject to extraneous acting force and produce slip.This will affect fault detector effect will be installed, and the timely and accuracy of reporting to the police is produced adverse consequences.Simultaneously, two end faces of opening current sensor also need locking, otherwise the magnetic circuit loss is large, affects measuring accuracy.
Summary of the invention
The purpose of this utility model is in order to make between current sensor in aerial conductor fault indicator and pole line and two end faces lockings of current sensor opening, a kind of latch mechanism to be provided.
The utility model provides a kind of latch mechanism of aerial conductor fault indicator to achieve the above object.It comprises lower house, upper shell,
Be positioned at the hook of the semicircle annular on upper shell,
Be positioned at the movable block of upper shell internal upper part,
Be positioned at the lower non-slipping block of hook on movable block,
Be positioned at the corresponding upper non-slipping block of hook inwall up and down non-slipping block,
Be positioned at the transmission shaft on the center below movable block, transmission shaft reaches in lower house always, and transmission shaft upper end and movable block are fixed, and the transmission shaft lower end is fixed on the base plate of lower house,
At the balancing spring of transmission shaft both sides between movable block and lower house upper surface,
Hollow rotating shaft between movable block one side is connected in upper shell and links up with, hollow rotating shaft lower end and upper shell are fixed, and the hollow rotating shaft upper end is fixing with hook,
Be connected in limited screw between upper shell and hook at the opposite side of movable block,
Lower non-slipping block on described movable block, movable block, hook on inwall upper non-slipping block and the center of transmission shaft all with lower house, upper shell and link up with on same center line.
Also comprise the top nut that transmission shaft upper end and movable block are fixing, the lower nut that transmission shaft lower end and lower house base plate are fixing.
Also comprise the fixing spindle nut of hollow rotating shaft lower end and upper shell that is connected between upper shell and hook, the rotating shaft register pin that hollow rotating shaft upper end and hook are fixed.
Locking member of the present utility model has obvious progress.
As above-mentioned structure of the present utility model, during use, aerial condutor is placed between aerial conductor fault indicator hook interior upper non-slipping block and lower non-slipping block, transmission shaft below the rotation movable block, movable block is moved up, make fastening between non-slipping block and lower non-slipping block, namely make aerial condutor and current sensor be close to, also make tight closure between two end faces of current sensor.When transmission shaft can not rotate again, pin transmission shaft, also just current sensor is locked on pole line.Balancing spring between movable block and lower house upper surface supports on the one hand movable block and moves up reposefully; The resilient support of balancing spring movable block and can not glided on the other hand, guarantees the position of having locked.Therefore, when moving, can not produce slip because of the acting force in the external world when aerial conductor fault indicator.And the magnetic circuit between two end faces of current sensor can not be affected yet, and has guaranteed measuring accuracy.Other component of aerial conductor fault indicator is placed in lower house, and wire is by drawing in hollow rotating shaft.So locking mechanism structure of the present utility model is simple, and is easy to use, safer more reliable in operation, can chargedly mount and dismount.The utility model is as using one lockset, aerial conductor fault indicator is locked on pole line, has both prevented that aerial conductor fault indicator from sliding on wire, make again it not be subjected to external force ground effect and affect the function of indicator, improve the accuracy that detects, extended serviceable life.
