Description

Technical Field

[0001] The utility model relates to the field of materials, and more specifically, to a multi-layer wall honeycomb core material. Background Art

[0002] The honeycomb structure has a large strength-to-weight ratio, can meet the requirements of large strength with a small cross-section, and can greatly reduce the self-weight of the structure itself. Therefore, the honeycomb structure has the advantages of good structural stability, good impact resistance and buffering performance. Especially, the aluminum honeycomb material itself has functions such as structural strength, heat preservation, fire prevention and sound insulation, and is widely used in various fields. For example, in the field of high-speed trains, the honeycomb core material is used in the manufacture of the carriages of high-speed trains.

[0010] The first clamping groove is snap-connected with the second protrusion, and the first protrusion is snap-connected with the second clamping groove, so that the first cross plate, the first bending plate, the second cross plate and the second bending plate are snap-connected into one body.

[0011] Further, a plurality of ventilation holes are uniformly arranged on the first horizontal plate and the second horizontal plate respectively.

[0012] Further, a plurality of threaded holes are also uniformly arranged on the first horizontal plate and the second horizontal plate respectively, and the ventilation holes and the threaded holes are arranged alternately in the same direction.

[0021] Second limiting grooves are respectively formed on the opposite side surfaces of the second horizontal plate and the first bent plate so that the limit plates are clamped in the second limiting grooves.

[0022] Further, first arc-shaped grooves are formed on the inner side walls of the first clamping groove and the second clamping groove, second arc-shaped grooves are formed on the inner side walls of the first protrusion and the second protrusion, and the first arc-shaped grooves and the second arc-shaped grooves are arranged oppositely so that a cylindrical cavity is formed between the first arc-shaped groove and the second arc-shaped groove.

[0027] By uniformly arranging a plurality of ventilation holes on the first cross plate, the second cross plate, the first bent plate and the second bent plate respectively, when the internal pressure of the core material is too high, the ventilation holes can effectively release the pressure, avoiding the fracture of the connection part caused by the impact of the internal high-pressure gas flow on the connection part of the bending plates.

[0028] By uniformly arranging a plurality of bolt holes on the first cross plate, the second cross plate, the first bent plate and the second bent plate respectively, the first bending plate and the second bending plate can be connected by bolts, greatly strengthening the connection strength. And when the ambient temperature is too high to use glue injection to strengthen the connection, bolt connection can be used instead, greatly increasing the application range of the present utility model.

[0029] By arranging the supporting part to provide a supporting force for the cavity of the present utility model, the problem of cavity collapse caused by too high external pressure is avoided.

[0030] By arranging a first arc-shaped groove on the inner side wall of the first clamping groove and the second clamping groove, and arranging a second arc-shaped groove on the inner side wall of the first protrusion and the second protrusion, the first arc-shaped groove and the second arc-shaped groove are arranged opposite to each other, so as to form a cylindrical cavity between the first arc-shaped groove and the second arc-shaped groove. When the first bending plate and the second bending plate are clamped, the internal gas can flow through the cylindrical cavity, making the clamping easier; after the first bending plate and the second bending plate are clamped, glue can be injected into the cylindrical cavity to strengthen the connection strength between the first bending plate and the second bending plate, avoiding loosening of the connection part between the first bending plate and the second bending plate.
