The purpose of this utility model is to avoid the deficiencies in the prior art part and provides a kind of cost cost low, the reclining good springiness of the chair back of the body, the Chair underpan that the reclining of the chair back of the body directly realizes by spring.

The purpose of this utility model reaches by following measure, it is by bottom, mid-game, last dish is formed, bottom is connected by steady pin with mid-game, mid-game can be rotated around steady pin, last dish is connected by steady pin with mid-game, mid-game drives to go up to coil and moves, in mid-game, be provided with fixed pin shaft, one end of spring is connected on the fixed pin shaft, the other end of spring is connected on the bottom by release handle, when central coiling steady pin rotates, spring pulling mid-game on the fixed pin shaft in the mid-game, last dish is connected by steady pin with mid-game, mid-game drives to go up to coil and moves, and mid-game is connected with the chair back of the body, and last dish is connected with the chair seat board, bottom is connected with Foot of chair, the reclining of the chair back of the body is directly by spring pulling mid-game, and the reclining size of the chair back of the body is relevant with the length that spring stretches, in order to control the reclining size of the chair back of the body, on the fixed pin shaft that is provided with in the mid-game, connect a tooth bar, one angle bar is set on bottom, and the tooth on the tooth bar cooperates with angle bar, when angle bar is stuck in tooth on the tooth bar, just fix the tensile elongation of spring, fixed the reclining size of the chair back of the body.

Easy to adjust for guaranteeing, on tooth bar top one shell fragment is set, in the tooth bar bottom one securing rod is set, one end of securing rod is connected on the bottom, and the other end passes the fixed bit on tooth bar bottom and the bottom, when upwards lifting securing rod, securing rod promotes tooth bar upwards, tooth on the tooth bar cooperates with angle bar, and securing rod is located at fixed bit, pushes away securing rod when downwards, securing rod is located at fixed bit, under the shell fragment effect of tooth bar top setting, it is downward to promote tooth bar, and the tooth on the tooth bar is cooperated with the angle bar disengaging.

The utility model reasonable in design reduces cost, the reclining good springiness of the chair back of the body, and the reclining of the chair back of the body realizes by spring that directly the reclining size of the chair back of the body is the location directly, is a kind of novel Chair underpan.
