Support structure and display device

The invention relates to the technical field of display, in particular to a support structure and a display device. The support structure is arranged at one side of a flexible display panel, and at least comprises a first bendable region; a bending axial line corresponding to the first bendable region extends in the first direction; the first bendable region is provided with a plurality of first main bending regions and a plurality of first deformation compensation regions; the first main bending regions and the first deformation compensation regions are alternately distributed in the first direction; each first main bending region comprises a plurality of first main strip-shaped holes in array distribution; the first main strip-shaped holes extend in the first direction; each first deformation compensation region comprises a plurality of groups of first hollow patterns in array distribution; each group of first hollow patterns are formed by combining a plurality of hollow holes; and at least two hollow holes in the plurality of hollow holes have different shapes or different extending directions. Through such a design, the structure stability of the support structure is ensured; and the anti-impact and bending-resistant performance of the flexible display panel is enhanced.

Direct thermal treatment process technology after rolling steel plate

The invention belongs to the technical field of metallurgy, in particular to a direct thermal treatment process technology after rolling a steel plate. The invention provides the direct thermal treatment process technology after rolling the steel plate, which can overcome the deficiencies of the prior art. The process technology comprises the steps of heating the steel plate on an outlet roller way of a rolling machine for quenching mainly, using a steel plate electromagnetic induction heating device arranged on the outlet roller way between a medium and heavy plate finish rolling machine and a post-rolling controlled cooling device which is a direct quenching and accelerated cooling device for heating and soaking the steel plate passing through the steel plate electromagnetic induction heating device according to the process requirements, and improving the flatness and the plate shape of the steel plate through a straightening roller matched with the electromagnetic induction heating device. The steel plate electromagnetic induction heating device with the straightening roller is arranged on the roller way between the medium and heavy plate finish rolling machine and the cooling device. The process technology can realize the one-line quenching thermal treatment process of the steel plates with various specifications. The process technology is applicable to new construction and transformation projects of medium and heavy plate plants. The process way and the devices have important popularization value.

Preparation process of double-surface flat glass steel plate for laboratory test

The invention relates to a preparation process of a double-surface flat glass steel plate for laboratory test. The preparation process is characterized in that glass-fiber cloth is laid on the upper surface of a glass working platform surface; a holed pressing plate is placed on the glass-fiber cloth; a flow guiding net is put on the area with small holes; a glue filling base is put on the flow guiding net, a breathable felt is laid and covers on the glass-fiber cloth; a winding pipe is put on the glass working platform surface and is covered by the breathable felt; one end of the winding pipe is connected with an exhaust pipe, and a vacuum film is laid and covers the winding pipe, the breathable felt, the glass-fiber cloth, the holed pressing plate, the flow guiding net and the glue filling base; the edge of the vacuum film is sealed by using a sealing rubber strip and is fixed on the glass working platform surface; one end of the exhaust pipe is connected with the winding pipe, the other end of the exhaust pipe is connected with a resin collector which is connected with a vacuum pump by the exhaust pipe. Compared with the prior art, the preparation process has the advantages that the flatness of a reinforced plastic plate product is improved and the influence of the demolding cloth on the reinforced plastic plate is avoided.

Curtain wall dry hanging multidirection adjusting pendant and construction method thereof

The invention relates to a curtain wall dry hanging multidirection adjusting pendant and a construction method of the curtain wall dry hanging multidirection adjusting pendant. The curtain wall dry hanging multidirection adjusting pendant is characterized in that in the process of construction, a machine threaded hole (1) is formed in the vertical face of an L-shaped corner connecting part (A) and is connected with an installation hole site (2) arranged on a curtain wall panel (C) through a machine screw spike (3), and a groove (4) which can be adjusted in a left-right mode is formed in the transverse plane of the L-shaped corner connecting part (A). After the transverse plane of the L-shaped corner connecting part (A) is flush with and attached to the transverse plane of an L-shaped corner connecting piece (B), a cross shape is formed by the groove (4) which can be adjusted in the left-right mode in the transverse plane of the L-shaped corner connecting part (A) and a groove (5) which can be adjusted in a front-back mode in the transverse plane of the L-shaped corner connecting part (B), and the groove (4) and the groove (5) are connected tightly through a screw spike (6). Installation and adjustment are easy, and a large amount of labor cost is reduced. Due to the fact that the pedant has the function of multidirection adjustment, the tolerance level for precision demands when a curtain wall is installed is improved, the flatness of the curtain wall is greatly improved, the structure is simple, firm and practical, and therefore a large amount of dragon frame rolled steel is saved; the safety performance indicators of installation nodes of each structure can be detected, calculated and controlled in advance.
