Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-5, an electromagnetic shielding case for electrical equipment comprises a rectangular bottom plate 1, two clamping plates 3, two movable plates 5 and apron 8, the mounting groove 2 of two symmetries is seted up to the upper end of time type bottom plate 1, two cardboard 3 respectively with the inner wall sliding connection of two mounting grooves 2, the top of two cardboard 3 all is equipped with the vertical dovetail 4 of two symmetries, a pair of vertical dovetail block 6 has all been welded to the lateral wall of two movable plates 5, two vertical dovetail block 6 respectively with the inner wall sliding connection of two vertical dovetail 4, horizontal dovetail 7 has all been seted up to one side that two cardboard 3 are close to mutually, the lateral wall welding of apron 8 has a pair of horizontal dovetail block 9, two horizontal dovetail block 9 respectively with the inner wall sliding connection of two horizontal dovetail 7, the inside of two mounting grooves 2 all is equipped with the stop device that two sets of symmetries set up, the upper end of time type bottom plate 1 is equipped with the auto-eject device that two sets.

Stop device has slider spring 13 including offering the transverse groove 12 at 2 lateral walls of mounting groove, the welding of the interior bottom of transverse groove 12, and slider spring 13 keeps away from the welding of the one end of the interior bottom of transverse groove 12 and has a location slider 14, and location slider 14 and transverse groove 12 inner wall sliding connection, location slider 14 are the spring bolt structure, are the inclined plane in the inside upper end of mounting groove 2, are made by the iron material.

Constant head tank 15 has all been seted up to the lateral wall of two cardboard 3, and the welding of the interior bottom of mounting groove 2 has spacing spring 16, and spacing spring 16 keeps away from the welding of the one end of the interior bottom of mounting groove 2 and has limiting plate 17.

The lateral wall of two cardboard 3 all welds fixed pin 10, and the circumference lateral wall of two fixed pins 10 all is connected with stopper 11 through the torsional spring rotation, and stopper 11 rotates the back and shows horizontal dovetail 7, and after horizontal dovetail 9 got into completely, unclamped stopper 11 back, it can shelter from horizontal dovetail 9, reaches the effect of fixed apron 8.

Automatic pop-up device is including seting up in the sliding tray 18 of returning type bottom plate 1 upper end, the interior bottom welding of sliding tray 18 has vertical spring 19, vertical spring 19 is kept away from the one end welding of the interior bottom of sliding tray 18 and is had iron attracting block 20, iron attracting block 20 is the permanent magnet, only when pressing iron attracting block 20 to sliding tray 18 bottom completely, iron attracting block 20 just can provide sufficient appeal to location slider 14, make it move to horizontal 12 bottoms in the groove, break away from constant head tank 15, and when iron attracting block 20 did not receive the pressure, iron attracting block 20 can't provide sufficient magnetic attraction to location slider 14.

Every vertical dovetail block 6 and horizontal dovetail block 9's surface all has the blotter glued, and the blotter is made by elastic rubber material, and when receiving the impact, the blotter has certain buffer capacity, and then reaches buffering effect.

In the utility model, in the installation process, firstly, install the clip type bottom plate 1 on the electronic component that needs protection, then insert two cardboard 3 to the mounting groove 2, in the insertion process, cardboard 3 can promote the motion of positioning slider 14, because positioning slider 14 stress surface is the inclined plane, can make positioning slider 14 move inwards along transverse groove 12, slider spring 13 is compressed simultaneously, when cardboard 3 crosses transverse groove 12 and continues downwards, positioning groove 15 reaches the position that positioning slider 14 is flat, positioning slider 14 can get into positioning groove 15 under the elastic action of slider spring 13, positioning slider 14 forms spacing to cardboard 3 at this moment, make it can't move upwards directly and break away from mounting groove 2;

meanwhile, the clamping plate 3 extrudes the limiting plate 17, the limiting spring 16 is extruded at the same time, the clamping plate 3 is loosened, the limiting plate 17 pushes the clamping plate 3 under the elastic action of the limiting spring 16 to enable the clamping plate 3 to be abutted against the positioning slide block 14, the clamping plate is prevented from moving randomly in the mounting groove 2, and another clamping plate 3 is mounted in the same way;

then, aligning the vertical dovetail blocks 6 welded on two sides of the moving plate 5 with the vertical dovetail grooves 4 formed in the clamping plate, and pressing down along the vertical dovetail grooves 4 until the bottom end of the moving plate 5 abuts against the upper end of the square-bottom plate 1; another moving plate 5 is installed in the same way;

then, the limiting block 11 is rotated, the transverse dovetail blocks 9 welded on the two sides of the cover plate 8 are aligned to the transverse dovetail grooves 7 on the clamping plate 3 and pushed in until the transverse dovetail grooves are completely inserted, then the limiting block 11 is loosened, then the limiting block 11 automatically resets under the action of the elasticity of the torsion spring to block the cover plate 8, so that the cover plate 8 is limited to move, and the whole shielding cover assembly is completed;

when the components need to be simply checked, only the limiting block 11 needs to be twisted, and the cover plate 8 is pulled out; the trouble of disassembling and assembling can be saved, and the effect of saving time can be achieved.

When needs overhaul components and parts by a wide margin, only need press 20 power of magnet piece, the location slider can receive magnet attraction, move to transverse groove 12 inside, thereby break away from constant head tank 15, and then remove the spacing effect to cardboard 3, at this moment, deformation will be resumeed to spacing spring 16, thereby promote cardboard 3 through limiting plate 17 and shift up, and then make whole shield cover take out easily, this process only needs to press magnet piece 20 and can take out, need not with the help of external instrument, and is easy and simple to handle, overhaul after the completion, insert cardboard 3 along mounting groove 2 again, reach spacingly, can reuse.

The dovetail block is connected with the clamping groove of the dovetail groove to have a certain anti-seismic effect, and the surface of the dovetail block is glued with rubber materials, so that the anti-seismic buffering effect of the dovetail block can be improved.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
