Abstract
The invention discloses a pressing device for a mobilephone shielding cabinet door. The pressing device comprises a sensor linkage rod fixed in a clamping groove in the side surface of the shielding door; locking points which are separately arranged up and down are arranged on the sensor linkage rod; locking blocks which are matched with the locking points of the sensor linkage rod are fixedly arranged on a door frame corresponding to the shielding door; a rotary shaft is accepted in an assembly hole of fan-shaped teeth of the sensor linkage rod; the other end of the rotary shaft penetrates out of a shaft hole in the shielding door and then is screwed into a threaded hole in a metal handle; and a plurality layers of metal outer sleeve pipes sleeve the outer circle of a metal shaft sleeve between the metal handle and the shielding door. According to the pressing device for the mobilephone shielding cabinet door, the multiple layers of metal outer sleeve pipes are arranged, so that an electromagnetic signal continuously attenuates during a transmission process, and an electromagnetic shielding effect is reached.
Description
Technical field
The present invention relates to electromangnetic spectrum field, particularly relate to a kind of mobile phone shielding cabinet door hold down gag。
Background technology
Mobile phone shielding cabinet can be used for blocking the communication being positioned between the internal all types of mobile phones of shielding cabinet and base station, effectively suppress the leakage of mobile telephone signal, it is adaptable to the centralized management of the mobile phone in the concerning security matters places such as Party and government offices, the office building of army, meeting room, examination place。The quality of mobile phone shielding cabinet airtight performance directly affects the shielding cabinet shield effectiveness to mobile phone signal, there is gap, it is easy to cause that signal is revealed between door metal handle and the corresponding shield door of mobile phone shielding cabinet shielding common on market。
Summary of the invention
It is an object of the invention to: in order to solve problem above, the invention provides a kind of novel mobile phone shielding cabinet door hold down gag。
The present invention solves that the technical scheme that above-mentioned technical problem provides is:
A kind of mobile phone shielding cabinet door hold down gag, including the driver gangbar in the draw-in groove being fixed on shield door side, driver gangbar is provided with the lock point split up and down, the doorframe corresponding with shield door is installed with the lock dog locking Point matching with driver gangbar, being set with rotating shaft in the installing hole of the sector of driver gangbar, after the other end of rotating shaft passes the axis hole on shield door, spinning enters in the screwed hole of metal handle。
Preferably, the axis hole of described shield door is set with metal axle sleeve, the shield door outer face seamless welding that the cylindrical of metal axle sleeve is corresponding, described rotating shaft is installed in the metal axle sleeve of correspondence, and the both ends of the surface of described metal axle sleeve extend respectively to sector and end face corresponding to metal handle。
Preferably, the metal axle sleeve cylindrical between described metal handle and shield door is set with some layers of metal jacket pipe。
Preferably, described metal jacket pipe includes the metal jacket pipe I being set in metal axle sleeve cylindrical and the metal jacket pipe II being set in metal jacket pipe I cylindrical, the end face seamless welding that the end face of metal jacket pipe I is corresponding with metal handle, the end face seamless welding that the end face of metal jacket pipe II is corresponding with shield door。
Mobile phone shielding cabinet door hold down gag of the present invention provides the benefit that:
The mobile phone shielding cabinet door hold down gag of the present invention is provided with multiple layer metal trocar sheath, constantly decays, reach the effect of electromagnetic shielding in the process that electromagnetic signal is propagated。

In figure: 1. shield door, 2. driver gangbar, 3. rotating shaft, 4. metal handle, 5. metal axle sleeve, 6. metal jacket pipe I、7.Metal jacket pipe II, 8. doorframe, 9. lock dog, 11. draw-in grooves, 21. lock point, 22. sectors。
Detailed description of the invention
The specific embodiment of the present invention is referring to Fig. 1-4, a kind of mobile phone shielding cabinet door hold down gag, structure and using method including the driver gangbar 2(driver gangbar in the draw-in groove 11 being fixed on shield door 1 side are prior art), driver gangbar 2 is provided with the lock point 21 split up and down, the doorframe 8 corresponding with shield door 1 is installed with lock point 21 lock dog 9 mated with driver gangbar 2, the installing hole of the sector 22 of driver gangbar 2 is set with rotating shaft 3, the axis hole of shield door 1 is set with metal axle sleeve 5, the shield door 1 outer face seamless welding that metal axle sleeve 5 is corresponding, the other end of rotating shaft 3 passes the screwed hole that rear spinning enters metal handle 4 from metal axle sleeve 5。The both ends of the surface of metal axle sleeve 5 extend respectively to sector 22 and the end face of metal handle 4 correspondence。Metal axle sleeve 5 cylindrical between metal handle 4 and shield door 1 is set with double layer of metal trocar sheath, including being set in the metal jacket pipe I 6 of metal axle sleeve 5 cylindrical and being set in the metal jacket pipe II 7 of metal jacket pipe I 6 cylindrical, the end face seamless welding that the end face of metal jacket pipe I 6 is corresponding with metal handle 4, the end face seamless welding that the end face of metal jacket pipe II 7 is corresponding with shield door 1。
One end of rotating shaft is fixed in sector, and the other end screws in the screwed hole of metal handle 4, easy disassembly；The end face seamless welding that the end face of metal jacket pipe I is corresponding with metal handle, the end face seamless welding that the end face of metal jacket pipe II is corresponding with shield door, outer signals is behind the gap between metal jacket pipe I and metal jacket pipe II, enter the gap between metal jacket pipe I and metal axle sleeve, last again from the gap entrance shielding cabinet between metal axle sleeve and rotating shaft, signal is constantly decayed in the process, and last signal is little to enter in shielding cabinet, reaches the effect of electromagnetic shielding。
