Abstract
The utility model relates to a mechanical interlocking latching device of a switching mechanism of a hand buggy, which comprises a transmission shaft, a switching mechanism, a couple axle, a switcher, a latching spring lamination and the like. The mechanical interlocking latching device is characterized in that the couple axle of the switching over mechanism is provided with a concave ring groove. When the couple axle is stretched and inserted into a guide rail groove of the switcher, the latching spring lamination is clamped in the concave ring groove, so that the couple axle and the switcher can not trip and are always maintained in a latching state, thereby reaching the purpose of preventing power failure as a switch can not be switched on due to trip and realizing the safe and reliable power supply running of the switch of the hand buggy. The device is simple in structure, simple and convenient to operate, reliable in performances and capable of ensuring normal power supply.
Description
Technical field
The utility model relates to the mechanical chain structure of wheelbarrow switch in a kind of power equipment, relates in particular to a kind of wheelbarrow switch mechanism mechanical chain locking device.
Background technology
In electric power system, in order to ensure the safe and reliable operation of generating, controller switching equipment and electric line, this also is one of primary and most important requirement.In defeated, power transformation operation, the wheelbarrow switch 95% or more is arranged, because of couple axle and switch disengaging, switching mechanism can't be threaded off and cause that closing coil switches on for a long time, cause closing coil to burn, and cause can not normal power supply to the user; Simultaneously if meet the circuit transient fault, can not reclosing and cause large-area power-cuts.Yet, prior art there is no the measure of the mechanical latching function of considering couple axle and switch, and this is a defective, for guaranteeing to reach safe and reliable power reguirements in the powered operation, prevent to cause the user to have a power failure, must adopt wheelbarrow switch mechanism mechanical chain locking device.
Summary of the invention
Goal of the invention of the present utility model is to overcome the defective of prior art and a kind of couple axle and switch disengaging that is in operation that prevents is provided, the wheelbarrow switch mechanism mechanical locking device that can reach and be in blocking all the time, guarantees the switch reliability service.
The foregoing invention purpose is realized by following technical proposals: a kind of wheelbarrow switch mechanism mechanical chain locking device, it comprises switch, be fixed with guide-track groove on the switch, the switching mechanism that connects power transmission shaft is inserted in the guide-track groove by the interlock shaft extension, it is characterized in that described couple axle is provided with concave ring groove, this couple axle snaps in the case spring sheet after inserting guide-track groove in concave ring groove.
Described power transmission shaft and switching mechanism are connected and fixed by connecting pin.
Compared with prior art, the beneficial effects of the utility model are: process concave ring groove on the couple axle of switching mechanism, after couple axle interts the guide-track groove of switch, snap in the couple axle concave ring groove with the case spring sheet, realize locking, it is simple in structure, and is easy and simple to handle, dependable performance, can guarantee that the power equipment wheelbarrow switch is in operation can't thread off couple axle and switch voluntarily, remain at blocking, guarantee the reliable normal operation of device security, guarantee normal power supply to the user.
Description of drawings
Fig. 1 is the utility model assembling perspective view.
Fig. 2 is the utility model exploded perspective structural representation.
Embodiment
Below more in conjunction with the accompanying drawings embodiment the utility model is described in detail.
Shown in Fig. 1～2, wheelbarrow switch mechanism mechanical chain locking device, constitute by power transmission shaft 1, switching mechanism 2, couple axle 3, switch 5 and case spring sheet 6 etc., power transmission shaft 1 inserts switching mechanism 2 one ends, do synchronous spinning movement with connecting pin 7 connections, the other end of switching mechanism 2 and couple axle 3 disjunctors also are provided with concave ring groove 4 on couple axle.In guide-track groove 8 is elongated is microscler guide rail hole, with switch 5 conjoined structures, is extruded by stainless steel.Being installed in couple axle 3 on the switching mechanism 2 stretches to be inserted in the guide-track groove 8 and utilizes its elasticity to snap in connection by case spring sheet 6.When switch 5 was done upper and lower operation, couple axle in the guide-track groove 83 is corresponding to be lifted or descends, and made switching mechanism 2 positive and negative rotations and drive power transmission shaft 1 to make positive and negative direction and rotate synchronously.During the positive direction rotation, switching mechanism closes a floodgate open, during opposite spin, and closing locking.
The utility model is in switch operation closing operation process, snapping in couple axle concave ring groove 4 with case spring sheet 6 implements to force couple axle 3 and switch 5 are carried out locking, couple axle and switch can't be broken away from, remain at blocking, guarantee the switch reliability service, reaching prevents to thread off because of machinery causes switch to close a floodgate the user being caused power failure, guarantee to reach safe and reliable power reguirements in the powered operation.
