Abstract
The utility model discloses a kind of fall insurance, including insulating bar, upper end is provided with the upper metal contact being connected with wire, and lower end is provided with the lower metal contact being connected with wire；Upper mounting bracket and lower mounting bracket, outer layer are insulator, and internal layer is the conductor turned on the upper metal contact and lower metal contact；Fusion tube, fuse is inside provided with, eutectic dotted line is additionally provided with fusion tube, eutectic dotted line one end is connected with winder, the lower end connection of the other end and fusion tube, and the pulling force of eutectic dotted line carrying is bigger than fuse.Fall insurance security of the present utility model is greatly improved, and has saved cost.
Description
Technical field
It the utility model is related to power supply locking device field, more particularly to fall insurance.
Background technology
There are the following problems for current fall insurance：Fall insurance fails to accomplish to form physical isolation with power supply after taking
(without obvious cut-off point), so inherently cause human casualty accident if fall insurance itself is breakdown.In order to ensure peace
Entirely, the generation of the above situation is prevented, currently used means are mostly following two：First, when carrying out fault detect every time
The power supply of whole piece circuit is all cut off, it is obvious that being to cause huge loss of outage the shortcomings that this mode, is brought not to user
Just；It is costly the shortcomings that this scheme, time-consuming second, starting with from transformation transformer device structure to solve, while also results in and stop
Electric loss.
In addition, when high-altitude installation drop type fusing insurance, tensioned state is in fusion tube, once install
The fusing insurance of inaccurate or drop type is come off from the air, and the fuse in fusion tube will be broken, and is sometimes installed a fusing and is protected
Danger may expend several fuses, substantially increase cost.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of security performance height, cost-effective fall insurance.
In order to solve the above-mentioned technical problem, scheme of the present utility model is：
Fall insurance, including insulating bar, upper end are provided with the upper metal contact being connected with wire, and lower end is provided with and wire
The lower metal contact of connection；Upper mounting bracket and lower mounting bracket, are vertically arranged with the insulating bar, the upper installation branch
Frame and the outer layer of lower mounting bracket are insulator, and internal layer is to be led with what the upper metal contact and lower metal contact turned on
Body；Fusion tube, it is arranged between the upper mounting bracket and the lower mounting bracket, fuse, institute is provided with the fusion tube
Conductor of the fuse both ends respectively with the upper mounting bracket and lower mounting bracket internal layer is stated to be connected；Also set up in the fusion tube
There are eutectic dotted line, described eutectic dotted line one end to connect after passing through the upper mounting bracket with the winder being placed in the insulating bar
Connect, the other end is connected with the lower end of the fusion tube, and the pulling force of the eutectic dotted line carrying is bigger than the fuse.
Preferably, the eutectic dotted line is the plastic cord of flat.
Preferably, operation ring is set on the fusion tube.
Preferably, the fusion tube upper end and the upper mounting bracket contact portion, lower end is hinged with the lower mounting bracket.
Compared with prior art, the beneficial effects of the utility model are：
Due to setting an eutectic dotted line in fusion tube, and the pulling force of eutectic dotted line carrying is bigger than fuse, so
When fall insurance works, eutectic dotted line is in tight state, and fuse does not have stress, even guarantor is fallen in installation
In the process of danger, there are problems that, fuse will not also disconnect easily, and when system jam, fault current makes guarantor
Dangerous silk fuses rapidly, forms electric arc, and produce heat so that eutectic dotted line fuses, and causes fusion tube to fall, and formation significantly cut-offs position
Put.The personal safety of staff, security greatly improve when ensuring that trouble hunting.
Brief description of the drawings
Fig. 1 is the structural representation of the fall insurance of the utility model embodiment.
Embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.Herein it should be noted that
It is used to help understand the utility model for the explanation of these embodiments, but does not form to restriction of the present utility model.This
Outside, as long as technical characteristic involved in each embodiment of the utility model disclosed below does not form conflict each other
Can is mutually combined.
Fig. 1, fall insurance of the present utility model, including insulating bar 1 are refer to, the upper end of insulating bar 1 is provided with to be connected with wire
The upper metal contact 2 connect, lower end are provided with the lower metal contact 3 being connected with wire.
Upper mounting bracket 4 and lower mounting bracket 5, are vertically arranged with the insulating bar 1, the upper mounting bracket 4 with
And the outer layer of lower mounting bracket 5 is insulator, internal layer is the conductor turned on the upper metal contact 2 and lower metal contact 3.
Fusion tube 6, it is arranged between the upper mounting bracket 4 and the lower mounting bracket 5, is provided with the fusion tube 6
Fuse 7, conductor of the both ends of fuse 7 respectively with the upper mounting bracket 4 and the internal layer of lower mounting bracket 5 are connected；Institute
State and eutectic dotted line 8 be additionally provided with fusion tube 6, described one end of eutectic dotted line 8 pass through the upper mounting bracket 4 after be placed in it is described absolutely
Winder 10 in edge rod 1 is connected, and the other end is fixedly connected with the lower end of the fusion tube 6, when the fusion tube 6 closes,
The pulling force of the line of low melting point 8 carrying is bigger than the fuse 7.Winder 10 is used to collapse the eutectic dotted line 8.
The eutectic dotted line 8 is the plastic cord of flat.
Operation ring 9 is set on the fusion tube 6.
The upper end of fusion tube 6 and the upper contact portion of mounting bracket 4, lower end are be hinged with the lower mounting bracket 5.
Due to setting an eutectic dotted line 8 in fusion tube 6, and the pulling force that eutectic dotted line 8 carries is bigger than fuse 7,
So when fall insurance works, eutectic dotted line 8 is in tight state, and fuse 7 does not have stress, even installation
During fall insurance, there are problems that, fuse 7 will not also disconnect easily, and when system jam, failure electricity
Stream makes fuse fuse rapidly, forms electric arc, and produce heat so that eutectic dotted line fuses, and causes fusion tube to fall, and is formed obvious
Cut-off position.The personal safety of staff, security greatly improve when ensuring that trouble hunting.
Embodiment of the present utility model is explained in detail above in association with accompanying drawing, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, it is right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall within the scope of protection of the utility model.
