Technical field
The utility model relates to a kind of micro switch box that is used to detect tubular type filming equipment memory block graphite boat.
Background technology
In the solar battery sheet manufacture process, the memory block of tubular film plating equipment all needs to install a micro switch box that is used for the graphite boat in the detection of stored district, as shown in Figure 1, described micro switch box 1 is installed the below that is arranged at described memory block support 5 by fixed structure 6 (for example Pi Pei screw bolt and nut etc.).As shown in Figure 2, existing micro switch box comprises box body 10 and is fixedly installed in the micro switch 2 of described box body 10 inside, described micro switch 2 has a switch contact 21 that projects upwards setting, be provided with a cylindricality push rod 30 that is used to push described switch contact 21 in the described box body 10, graphite boat transmits signals by pushing cylindricality push rod 30 downwards to described micro switch 2.
Thisly directly graphite box effect pressure is thereon passed to equally switch contact 21 by cylindricality push rod 30 and open the mode that triggers micro switch, security reliability is very poor, very possible situation about taking place is: graphite boat is arranged on the memory block, and cylindricality push rod 30 does not depress the switch contact 21 of micro switch 2, cause micro switch 2 not transmit correct signal and give system, system is thought not to be had graphite boat on the memory block and thinks that this memory block is idle, at this moment system just may be put into another boat on this memory block, thereby causes the generation of hitting the boat accident.
The utility model content
At above-mentioned problems of the prior art, the purpose of this utility model is to provide a kind of micro switch box that is used to detect tubular type filming equipment memory block graphite boat, this micro switch box can be beneficial to be installed in its inner micro switch accurately, reliable reception opens and closes signal, can effectively improve the accuracy that graphite boat detects.
To achieve these goals, a kind of micro switch box that is used to detect tubular type filming equipment memory block graphite boat that the utility model provides comprises box body and is fixedly installed in the interior micro switch of described box body that the top of described micro switch has switch contact, wherein,
Also be provided with a push rod that is used to push described switch contact in the described box body, described push rod is laterally by being located on the described switch contact, one end and the described box side wall of described push rod are hinged, and the other end of described push rod is bent upwards to form and passes the press section that described box body is pushed for graphite boat.
As preferably, the angle of bend of the end that described push rod is bent upwards is 90 degree.
Described tubular film plating device storage district has the memory block support, and the position of corresponding described press section offers through hole on the support of described memory block.
Described micro switch box is installed on the support of described memory block by fixed structure, and described press section protrudes upward and is higher than the memory block support along through hole.
Described fixed structure comprises the screw bolt and nut of coupling.
Compared with prior art, micro switch box of the present utility model utilizes the lever principle transmission to open and close signal and gives micro switch, increased be applied on the switch contact pressure, micro switch is transmitted signal more accurately and reliably, effectively improved the accuracy that graphite boat detects, thereby effectively avoided hitting the generation of boat accident, improved the fail safe of producing.

Embodiment
Below in conjunction with accompanying drawing the utility model structure is further specified.
As shown in Figure 3, a kind of tubular film plating device storage district graphite boat that the utility model provides detects uses the micro switch box, comprises box body 20 and the micro switch 2 that is fixedly installed in the described box body 20, and the top of described micro switch 2 has switch contact 21, wherein,
Also be provided with a push rod 3 that is used to push described switch contact 21 in the described box body 20, described push rod 3 is laterally by being located on the described switch contact 21, one end and the described box body 20 of described push rod 3 are side walls hinged, and the other end of described push rod 3 is bent upwards and forms the press section 31 that passes described box body 20 and push for graphite boat.
As shown in Figure 1 and Figure 4, described tubular film plating device storage district has memory block support 5, corresponding press section 31 offers through hole 51 on it, described micro switch box 20 is installed on the described memory block support 5 by fixed structure 6, and described press section 31 protrudes upward and is higher than memory block support 5 along through hole 51.Described fixed structure 6 can be the screw bolt and nut of coupling.
The mentality of designing of micro switch box of the present utility model is to utilize lever principle to increase the action moment of push rod, thereby guarantees accurately to detect in the tubular film plating device storage district whether have graphite boat.When curved press section 31 of establishing was subjected to pushing of graphite boat on the memory block on the push rod 3, push rod 3 rotated around pin joint 32, triggers described micro switch 2 thereby described switch contact 21 is subjected to pushing of push rod 3.Because the distance of described press section 31 and pin joint 32 is greater than the distance of described switch contact 21 with described pin joint 32, according to principle of moment balance, the pressure of the graphite boat that the pressure that described switch contact 21 is subjected to is subjected to greater than press section 31, therefore switch contact 21 can be pushed fully, make micro switch 2 correctly trigger and pass out correct signal reliably, avoid hitting the generation of boat accident.The curved angles of establishing in press section 31 can influence the size of carry-over moment, and the moment size can influence the efficient and the reliability of transmission, and as preferably, as shown in Figure 3, push rod 3 is bent upwards 90 degree and forms press sections 31.
In the prior art, when being installed in micro switch box 1 on the memory block support 5, micro switch box 1 can be arranged in the through hole 51 with mosaic mode, the cylindricality push rod 30 that is used to transmit signal accordingly from the memory block support 5 oval-shaped through hole 51 stretch out, in order to the graphite boat in detection of stored district; In addition, because that cylindricality push rod 30 takes up room is little, micro switch box 1 can be installed in the bottom of memory block support 5, cylindricality push rod 30 stretches out other through hole that is complementary (not shown) from memory block support 5 accordingly.Push rod 3 of the present utility model takes up room greatly, as shown in Figure 4, when being installed in micro switch box 2 on the memory block support 5, micro switch mounting box 20 of the present utility model is installed on the described memory block support 5 by fixed structure 6, it also is arranged in the through hole 51 with mosaic mode simultaneously, and the press section 31 on the described push rod 3 protrudes upward and is higher than memory block support 5 (as shown in Figure 3) along through hole 51.
Certainly; the above is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also are considered as protection range of the present utility model.
