Problems solved by technology

[0002] Seats can be divided into venue seats, car seats, family seats, etc. according to the place of use; according to the material, they can be divided into wooden seats, plastic seats, aluminum alloy seats, etc.; The back or other parts are usually equipped with small table boards for carrying various items. When the small table boards are in use, due to the lack of fixing devices for the small table boards, the small table boards are easy to find and rotate, which makes the actual application effect unsatisfactory.

Embodiment 1

[0054] Weigh 13.1g of dibromoneopentyl glycol, 10.1g of triethylamine and 100mL of acetone into a three-necked flask, add 9.2g of phenylphosphonic dichloride dropwise under ice bath, nitrogen protection and magnetic stirring, and dropwise add Then continue to react for 4 hours; after the reaction, remove the triethylamine salt by filtration, dichloromethane is added after the filtrate is distilled off under reduced pressure, and washed three times with saturated saline and deionized water successively, and the organic phase is washed with anhydrous magnesium sulfate After drying for 4 hours, the solvent was distilled off under reduced pressure to obtain a light yellow viscous liquid bromine-containing halogenated polyorganophosphoric ester polyol. After experimental detection, Mn: 2500g / mol (GPC), PDI = 1.7; hydroxyl value = 51.4mgKOH / g.

Embodiment 2

[0056] Weigh 8.65g of dichloroneopentyl glycol, 10.1g of triethylamine and 100mL of acetone into a three-necked flask, add 9g of phenylphosphonic dichloride dropwise under ice bath, nitrogen protection and magnetic stirring, after the dropwise addition Continue the reaction for 4 hours; after the reaction, remove the triethylamine salt by filtration, distill the filtrate under reduced pressure to remove the solvent, add dichloromethane, and wash with saturated saline and deionized water three times in turn, and dry the organic phase with anhydrous magnesium sulfate After 4 hours, the solvent was distilled off under reduced pressure to obtain light yellow chlorine-containing halogenated polyorganophosphoric ester polyol. After experimental detection, Mn: 2100g / mol (GPC), PDI = 1.6; hydroxyl value = 57.2mgKOH / g.

Embodiment 3

[0058] Weigh 7.75g of 3-bromo-1,2-propanediol, 10.1g of triethylamine and 100mL of acetone into a three-necked flask, add 9.0g of phenylphosphonic dichloride dropwise under ice bath, nitrogen protection and magnetic stirring, dropwise After the addition, the reaction was continued for 4 hours; after the reaction, the triethylamine salt was removed by filtration, the filtrate was evaporated under reduced pressure to remove the solvent, and dichloromethane was added, and washed three times with saturated saline and deionized water successively, and the organic phase was washed with anhydrous After drying over magnesium sulfate for 4 hours, the solvent was distilled off under reduced pressure to obtain light yellow bromine-containing halogenated polyorganophosphorous ester polyol. After experimental detection, Mn: 2300g / mol (GPC), PDI = 1.8; hydroxyl value = 55.3mgKOH / g.

Abstract

The invention discloses a four-in-one seat, which comprises a base, a seat plate arranged on the base, a back plate arranged on the side of the seat plate facing away from the base, and two armrest plates respectively arranged on both sides of the seat plate A cavity for people to sit is formed between the seat board, the back board, and the two armrest boards. The side of the armrest board facing away from the seat board is provided with a receiving groove, and a desktop assembly is slidingly arranged in the receiving groove. The desktop assembly includes mutually hinged Skateboard and table board. The table board is located on the side of the slide board facing away from the seat board. A first spring for keeping the table board moving to the storage tank is arranged in the storage tank. The first spring is connected to the inner wall of the storage tank, and the other end is connected to the slide board. Above, the armrest board is also provided with a fixing component, when the table board moves back to the receiving groove, the first spring stretches, the table board breaks away from the receiving groove and rotates toward the cavity, and the fixing member locks the table board to keep the table board and the armrest board in a vertical position In this state, the present invention is provided with a fixing assembly for locking the table top, which improves the stability of the table top.

Description

technical field [0001] The invention relates to the technical field of seats, and more specifically relates to a four-in-one seat. Background technique [0002] Seats can be divided into venue seats, car seats, family seats, etc. according to the place of use; according to the material, they can be divided into wooden seats, plastic seats, aluminum alloy seats, etc.; The back or other parts are usually provided with a small table for carrying various items. When the small table is in use, due to the lack of a fixing device for the small table, the small table is easy to find and rotate, making the actual application effect unsatisfactory. Contents of the invention [0003] In view of the deficiencies in the prior art, the object of the present invention is to provide a four-in-one seat, which is provided with a fixing assembly for locking the table, which improves the stability of the table. [0004] In order to achieve the above object, the present invention provides the...
