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. The four-in-one seat comprises a base, a seating plate, a leaning plate and two handrail plates; the seating plate is arranged on the base; the leaning plate is arranged on one surface of the seating plate back onto the base; the two handrail plates are respectively arranged at two sides of the seating plate; a cavity for a person to sit is formed amongthe seating plate, the leaning plate and the two handrail plates; a containing groove is arranged one surface of the handrail plate back onto the seating plate; a table top assembly is glidingly arranged in the containing groove; the table top assembly comprises a sliding plate and a table plate, which are mutually hinged; the table plate is positioned at one side of the sliding plate back onto the seating plate; a first spring used for keeping moving of the table plate to the containing groove is arranged in the containing groove; the first spring is connected onto the inner wall of the containing groove; the other end of the first spring is connected onto the sliding plate; the handrail plate is also provided with a fixing assembly; when the table plate moves back onto the containing groove, the first spring is elongated; the table plate is separated from the containing groove, and rotates towards the cavity; the fixing assembly locks the table plate; and thus, the table plate and the handrail plate are kept in a vertical state. According to the four-in-one seat in the invention, the fixing assembly used for locking the table plate is arranged; and thus, the stability of the table plate is improved.

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...
