[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] See also Figure 1-3 A hollow flame-retardant heat-insulating structure for wires and cables comprises a flame-retardant heat-insulating shell 1 and an adjusting mechanism 2. The internal material of the flame-retardant heat-insulating shell 1 comprises a flame-retardant layer 9 and a heat-insulating layer 10 in sequence. One end of the heat-insulating layer 10 is connected to one end of the flame-retardant layer 9. The adjusting mechanism 2 comprises a connecting block 3, a groove 4, a bearing 5, a bolt 6, a clamping block 7 and an arc plate 8. The connecting block 3 is arranged on the inner wall of the flame-retardant heat-insulating shell 1. The groove 4 is opened on the connecting block 3. One end of the bolt 6 passes through the flame-retardant heat-insulating shell 1 and extends into the groove 4 to be connected with the bearing 5. One end of the clamping block 7 extends into the groove 4 and is connected to the bolt 6 through the bearing 5. The adjusting mechanism 2 is provided with multiple ones.
[0020] When in use, first extend the wires and cables into the flame retardant and heat-insulating shell 1 so that the wires and cables are in contact with the arc plate 8. The interior of the flame retardant and heat-insulating shell 1 adopts a hollow setting, which can improve the insulation effect and prevent the external temperature from being directly transmitted to the wires and cables. The flame retardant layer 9 in the flame retardant and heat-insulating layer 10 can achieve the flame retardant effect, and the heat insulation layer 10 in the flame retardant and heat-insulating layer 10 can achieve the heat insulation effect. When large-sized wires and cables need to be placed in the flame retardant and heat-insulating shell 1, (the wires and cables placed in this structure at the beginning are the smallest size on the market), first tighten the bolt 6 to make the bolt 6 rise in the flame retardant and heat-insulating shell 1, so that the block 7 connected to the bolt 6 through the bearing 5 rises in the initial groove 4 on the connecting block 3, thereby driving the arc plate 8 to rise, so that the direct spacing between multiple arc plates 8 becomes larger, and it can be adjusted to a position matching the wires and cables, and then wires and cables of different sizes can be placed.
[0021] The stability of the above-mentioned adjustment mechanism 2 is relatively poor. In order to solve this problem, in this embodiment, a plurality of the adjustment mechanisms 2 are symmetrically arranged.
[0022] The flame retardant layer 9 may be made of any material. In order to improve the flame retardant effect, in this embodiment, the flame retardant layer 9 is made of flame retardant rubber material.
[0023] The thermal insulation layer 10 may be made of any material. In order to improve the thermal insulation effect, in this embodiment, the thermal insulation layer 10 is made of ceramic fiber.
[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
