Technical field
The utility model relates to a kind of switching device of power supply, is specifically related to a kind of duplicate supply mechanical interlock, belongs to the electrical accessorie technical field.
Background technology
At present, in the distribution technique field, on some circuit or equipment, duplicate supply is installed, for the safety that guarantees electricity consumption and equipment the useful life that increases equipment, generally can set up interlock at the switch place of duplicate supply, this interlock can realize that one of power supply opens one and close, convenient control and maintenance, but there are some faults of construction in current power interlock device.Interlock as the disclosed a kind of twin-power switch of Chinese patent ZL201120248695.7, it comprises mounting base, installing rack and two mains switches, the surrounding of described mounting base has chimb, and installing rack takes the shape of the letter U, and Open Side Down, and is fixed on the center of mounting base; Also comprise interlocking lever, described mains switch is placed on mounting base, is positioned at the both sides of installing rack, and fixes by screw and installing rack; The center line of described installing rack is provided with rotating shaft, the center line of interlocking lever has the hole coordinated with rotating shaft, and by rotary moveable be fixed on installing rack, the two ends of described interlocking lever are equipped with U-shaped interlock slot, the size of interlock slot is corresponding with the control lever size on mains switch, and control lever can rotate along hole.This scheme can realize the interlocking of mains switch, and simple in structure, but it can only realize that two mains switches one open one and close use, the plectrum of two switches need be allocated to plumbness in the time that overhaul of the equipments need to being carried out, but, because interlocking lever can rotate, plectrum can't keep plumbness for a long time, slightly there is rotation will make a mains switch close a floodgate, and can't close two mains switches simultaneously, there is larger potential safety hazard during maintenance.
The utility model content
In order to solve the above-mentioned technical problem existed in prior art, the utility model aims to provide a kind of simple in structure, simple operation, duplicate supply mechanical interlock safe, durable in use, with low cost.
The utility model is achieved by the following technical solution:
A kind of duplicate supply mechanical interlock, comprise downward opening U-shaped support; Described U-shaped cradle top surface middle part has chute, and the chute below is provided with slide plate, and slide plate and support are slidably connected, and the slide plate middle part is connected with handle, and handle is placed in chute.
Described U-shaped frame bottom is provided with flange.
Have some installing holes on described flange.
Described chute is to be opened in the waist-shaped hole that U-shaped props up top of the trellis.
The vertical component edge of described U-shaped support both sides also is provided with guide vane end stop.
Described guide vane end stop is the rectangle be rounded down.
Described handle is cylindrical.
The beneficial effects of the utility model are:
Compared with prior art, the duplicate supply mechanical interlock that the utility model provides, it adopts the slide plate that can horizontally slip to control opening or closing of duplicate supply, interlocking state is stable, not there will be trip problem, safety and stability, and close when can realize twin-power switch, staff's life safety can be guaranteed during repair apparatus; This device has simple in structure, simple operation, the characteristics such as safe, durable in use, with low cost simultaneously, is suitable for large-scale popularization and uses.
The accompanying drawing explanation
Fig. 1 is structure chart of the present utility model;
Fig. 2 is use view of the present utility model;
In figure: 1-guide vane end stop, 2-chute, 3-handle, 4-slide plate, 5-U shape support, 6-installing hole, 7-flange, 8-circuit breaker A, 9-circuit breaker B, 10-mounting panel.
Embodiment
Below in conjunction with drawings and Examples, the technical solution of the utility model is described further, but that desired protection range is not limited to is described;
As shown in Figure 1, the duplicate supply mechanical interlock that the utility model provides, comprise downward opening U-shaped support 5; Described U-shaped support 5 end face middle parts have chute 2, and chute 2 belows are provided with slide plate 4, and slide plate 4 is slidably connected with support 5, and slide plate 4 middle parts are connected with handle 3, and handle 3 is placed in chute 2.Drive horizontally slipping of slide plate 4 by handle 3, can control the switching of two circuit breakers, convenient and practical.
In order to facilitate installation of the present utility model, described U-shaped support 5 bottoms are provided with flange 7.
In order to ensure installation steadiness of the present utility model, have some installing holes 6 on described flange 7.
In order to guarantee the quick sliding of handle 3, described chute 2 is for being opened in the waist-shaped hole at U-shaped support 5 tops.
The vertical component edge of described U-shaped support 5 both sides also is provided with guide vane end stop 1, and the stability that it can guarantee after the utility model is installed, prevent distortion.
For fear of scratching circuit breaker or staff, promote security performance, the rectangle of described guide vane end stop 1 for being rounded down.
For lifting operation sense and security performance, described handle 3 is cylindrical.
Embodiment:
As shown in Figure 2, circuit breaker A8 and circuit breaker B9 all are fixed on mounting panel 10 both sides, the spacing reserved between assurance circuit breaker A8 and circuit breaker B9 can be held the utility model, the utility model is embedded between circuit breaker A8 and circuit breaker B9, promote U-shaped support 5 downwards, the flange 7 of its bottom is flushed with mounting panel 10, and with screw (in figure for illustrating), that flange 7 is fixing, guarantee after installation that guide vane end stop 1 is placed in circuit breaker A8 and circuit breaker B9 outer wall, during use, circuit breaker A8 need be closed a floodgate, when circuit breaker B9 disconnects, sliding handle 3 to the right, slide plate 4 synchronously moves to right, after handle 3 slides into chute 2 right side edge, it is the slip limit of slide plate 4, now can realize that circuit breaker A8 closes a floodgate, circuit breaker B9 disconnects.In the time of circuit breaker A8 disconnection, circuit breaker B9 need being closed a floodgate, sliding handle 3 left, and slide plate 4 synchronously moves to left, and after handle 3 slides into chute 2 left side edge, the slip limit of slide plate 4, realize that circuit breaker A8 disconnects, circuit breaker B9 closes a floodgate.In the time of need guaranteeing that circuit breaker A8 and circuit breaker B9 disconnect simultaneously, sliding handle 3, make it be placed in chute 2 middle parts, slide plate 4 also is placed in circuit breaker A8 and circuit breaker B9 middle part simultaneously, circuit breaker A8 and circuit breaker B9 all can not close a floodgate, disconnect when realizing two circuit breakers, just can carry out overhaul of the equipments, guarantee staff's life safety.
