[0002] The double insulation structure of the shielded door base is a design for the door base to provide double insulation for enhanced safety and reduce electromagnetic interference or noise through shielding. This design usually includes two layers of insulation materials, one of which is usually an inner insulation layer and the other is an outer shielding layer to prevent external interference, which can improve the stability and reliability of the equipment, extend the service life of the equipment, and reduce maintenance costs;

[0003] The traditional double insulation structure of the screen door base is achieved by placing an insulating mat on the equipment surface and then fixing it to the platform with screws or bolts;

[0004] The traditional double insulation structure of the shielding door base has the following problems: the fixing may be loose or uneven, which may easily cause the insulation pad to move or loosen during use, thereby reducing the insulation effect. For this reason, we propose a double insulation structure of the shielding door base. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a double insulation structure of a shielding door base, including a platform, a threaded opening and a mounting opening;

[0007] Platform: The upper surface of the platform is provided with a rubber pad, the upper surface of the rubber pad is provided with a polyurethane pad, the upper surface of the polyurethane pad is installed with a base, the upper surface of the base is provided with a slide rail, and the inner wall of the slide rail is slidably connected with a shield door;

[0008] Threaded opening: It is opened at the left end of the upper surface and the left inner wall of the platform respectively;

[0009] Installation opening: The left end of the upper surface of the rubber pad and the polyurethane pad and the left inner wall, and a mounting mechanism is provided between the installation opening and the adjacent threaded opening, which can provide a more stable fixation and a more uniform fit between the insulating pad and the shielding door base, and effectively prevent the insulating pad from moving or loosening during use.

[0010] Furthermore, the installation openings are coincident with the central axes of the adjacent threaded openings, thus ensuring smooth installation.

[0011] Furthermore, the installation mechanism includes an insertion column and an external threaded groove. The insertion column is inserted between the installation port and the inner wall of the adjacent threaded port. The outer surface of the insertion column is provided with an external threaded groove. The external threaded groove is threadedly connected to the inner wall of the adjacent threaded port to ensure the stability of the insertion column.

[0012] Furthermore, the installation mechanism also includes a slide groove, an extrusion plate and an inclined groove. The slide grooves are all opened in the middle of the column. The inner walls of the slide grooves are slidably connected with the extrusion plates. The ends of the extrusion plates away from the center of the column are cooperated and installed with the inner walls of the adjacent installation ports. The ends of the extrusion plates close to the center of the column are provided with inclined grooves to ensure that the two insulating pads are firmly fixed and tightly fitted.

[0013] Furthermore, the installation mechanism also includes springs, sliding columns and sliding holes. The sliding holes are all opened on the inner walls of the slide grooves. The inner walls of the sliding holes are slidably connected with sliding columns. The ends of the sliding columns close to the centers of the plugs are fixedly connected to the outer side surfaces of the adjacent extrusion plates.

[0014] Furthermore, the installation mechanism also includes bolts and internal thread grooves, and the internal thread grooves are all opened on the inner wall of the plug column. The inner wall of the internal thread groove is threadedly connected with the bolt to drive the extrusion plate to move.

[0015] Furthermore, the installation mechanism also includes a rubber sleeve, which is sleeved on one end of the bolt close to the center of the platform to prevent electrical connection between the bolt and other metal parts.

[0016] Compared with the prior art, the utility model has the following beneficial effects: the double insulation structure of the shielding door base has the following advantages:

[0017] The bolt is threadedly connected to the internal thread groove on the inner wall of the column, so that the bolt moves along the adjacent axis of the column. When the bolt moves, the bolt gradually contacts the inclined groove on the extrusion plate, and pressure is applied to make the extrusion plate move in the slide groove along the axis of the slide column through the slide hole. When the bolt moves to the deepest part of the column, the extrusion plate is completely squeezed out of the slide groove by the bolt, and the spring is fully stretched at the same time. The stretched spring makes the extrusion plate contact and squeeze the mounting openings on the adjacent rubber pad and polyurethane pad, thereby ensuring that the two insulating pads are firmly fixed and tightly fitted between the insulating pad and the shielding door base, thereby effectively preventing them from moving or loosening during use.
