The utility model belongs to the technical field of VR (virtual reality) interactive chairs, in particular to a chassis structure of a VR interactive chair, which aims at solving the problem of stability and comprises a base, a first sliding groove is formed in the outer surface of the base. A third sliding groove is formed in the outer surface of the base. A second sliding groove is formed in the inner surface of the first sliding groove. The inner surface of the first sliding groove is fixedly connected with an electric push rod. The upper surface of the base is fixedly connected with a connecting column; a first guide rod is arranged on the upper side of the inner surface of the third sliding groove. A second guide rod is arranged on the lower side of the inner surface of the third sliding groove. A first sliding block is fixedly connected to the inner surface of the first sliding groove. Second sliding blocks are fixedly connected to the outer surfaces of the two sides of the first sliding block. An inner groove is formed in the rear surface of the first sliding block. The front surface of the first sliding block is fixedly connected with a supporting plate. A third sliding block is fixedly connected to the outer surface of one side of the supporting plate. And through the arrangement of the supporting plate, the occupied area of the base can be changed, and the stability is improved.

This utility model discloses an integrated welding and marking device for automotive door sill beam welding assemblies, including a fixture base, a laser marking device, a servo welding gun, multiple L-shaped clamps, and a control box. The laser marking device and servo welding gun are fixed to the fixture base, and the L-shaped clamps are bolted to the top of the base, holding the door sill beam welding assembly. The servo welding gun is fixed to the upper part of the base via a bracket, performing welding above the part; the laser marking device is mounted on the bottom of the base via a fixed frame, performing back marking below the part. The control box is bolted to the side of the base, and cables connect the marking device and the welding gun via wiring channels. This device, through its integrated structure, simplifies the process flow, reduces part transfer, lowers the rate of missing, damaged, and misplaced QR codes, saves logistics time and equipment space, improves production efficiency and traceability reliability, and is suitable for the automated production of various door sill beam welding assemblies.

The invention belongs to the field of flue gas purification, and particularly discloses an activated carbon flue gas purification system and process based on cooperative operation of double desorption towers. The system comprises an adsorption unit, an analysis unit and an activated carbon conveyor. The adsorption unit comprises a gas inlet channel, an adsorption device, a gas outlet channel and a chimney, and smoke enters the adsorption device through the gas inlet channel to be purified, then enters the chimney through the gas outlet channel and is exhausted. And the adsorption device at least comprises an adsorption tower. And the analysis unit comprises a first analysis tower and a second analysis tower. The activated carbon conveyor can drive activated carbon saturated in the adsorption tower to enter the first desorption tower and the second desorption tower respectively for desorption and regeneration, and the regenerated activated carbon is conveyed back to the adsorption tower again, so that continuous purification of flue gas and efficient regeneration of the activated carbon are guaranteed. Through the cooperative layout of the adsorption units and the double desorption towers, the conveying efficiency of activated carbon can be improved, the flue gas purification efficiency is further improved, and the occupied area of equipment can be remarkably reduced.
