Description
Technical field
The present invention relates to a kind of protective device for plug-in strip.
Background technology
Knife switch is contactor the most common; way circuit usually used as domestic circuit controls whole circuit; knife switch is mainly divided by isolation between power supply and circuit, is closed circuit; but because plug-in strip does not have limiting and protecting device; therefore we are easy to because misoperation causes plug-in strip to be disconnected in daily use procedure; cause whole down circuitry, serious even can cause damage to electrical equipment, very dangerous.
Summary of the invention
The technical problem to be solved in the present invention is: for solving above-mentioned Problems existing, provides a kind of protective device for plug-in strip, solves common plug-in strip easily because scrape the problem of touching and causing plug-in strip to disconnect by mistake by mistake.
The technical solution adopted for the present invention to solve the technical problems is: a kind of protective device for plug-in strip, comprise base plate and the contact knife with base plate hinged, contact knife upper end is fixedly connected with seal, seal upper surface offers chute, seal is provided with the stopping means for preventing contact knife from overturning, stopping means lower surface has the bar shaped slide block matched with chute, stopping means inserts chute by slide block and is connected with seal, stopping means upper surface is provided with the electronic thermometer for displays temperature, electronic thermometer inside is provided with the battery for powering to electronic thermometer.
Further, chute inwall is provided with skid resistant course.
Further, outside face thereof is provided with skid resistant course.
The invention has the beneficial effects as follows, the protective device for plug-in strip of the present invention is provided with the stopping means for preventing contact knife from overturning, and greatly promotes the fail safe of plug-in strip, and the environment for use observing plug-in strip is also convenient in the design of electronic thermometer in addition.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
1. base plates, 2. contact knife, 3. seal, 4. stopping means, 5. electronic thermometer in figure.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
A kind of protective device for plug-in strip as shown in Figure 1, comprise base plate 1 and the contact knife 2 hinged with base plate 1, contact knife 2 upper end is fixedly connected with seal 3, seal 3 upper surface offers chute, seal 3 is provided with the stopping means 4 for preventing contact knife 2 from overturning, stopping means 4 lower surface has the bar shaped slide block matched with chute, stopping means 4 inserts chute by slide block and is connected with seal 3, stopping means 4 upper surface is provided with the electronic thermometer 5 for displays temperature, electronic thermometer 5 inside is provided with the battery for powering to electronic thermometer 5, further, chute inwall is provided with skid resistant course, further, outside face thereof is provided with skid resistant course, protective device for plug-in strip of the present invention is provided with the stopping means 4 for preventing contact knife from overturning, greatly promote the fail safe of plug-in strip.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to right.
