Similarly, the seat 3 can be adjusted first, and then the backrest 2 can be adjusted.
The first matching structure comprises a first adjusting gear 62, the first adjusting structure comprises a first adjusting rod 61, the first adjusting gear 62 is fixedly sleeved at the end part of the chair back rotating shaft 4 penetrating out of the support structure 11, and a certain gap is required to be reserved between the first adjusting gear 62 and the support structure 11 to avoid collision and interference; one end of the first adjusting rod 61 is connected to the end of the swing rod rotating shaft 52 penetrating out of the frame plate 1, the other end can extend into the space between the adjacent gear teeth of the first adjusting gear 62, so that the first adjusting gear 62 can be prevented from rotating, the combination of the first adjusting structure and the first matching structure can be realized, small-amplitude rotation can be generated for avoiding the first adjusting gear 62, the first adjusting rod 61 radially extends into the space between the adjacent gear teeth of the first adjusting gear 62 in a deviation manner, when the swing rod rotating shaft 52 is rotated by pushing the gear lever 53, the first adjusting rod 61 can be pulled out from the first adjusting gear 62, so that the first adjusting gear 62 is not interfered with the rotation of the first adjusting gear 62 any more, and the turnover of the chair back 2 is realized.
The connection relation between the first adjusting rod 61 and the swing rod rotating shaft 52 can be rigid connection or movable connection, if rigid connection is adopted, when the gear lever 53 is pushed to enable the first adjusting rod 61 to be pulled out from the adjacent gear teeth of the first adjusting gear 62, the first adjusting rod 61 and the first adjusting gear 62 generate large friction, so that the loss is aggravated, the service life is shortened, the phenomenon that the first adjusting rod 61 is clamped is easy to occur, the stress load at the connection part of the first adjusting rod 61 and the swing rod rotating shaft 52 is also very large, the situation that a local structure is damaged or bent and deformed is easy to occur, and therefore the movable connection is preferably adopted between the first adjusting rod 61 and the swing rod rotating shaft 52.
A first positioning column 63 is arranged at the position, deviating from the center point, of the shaft end surface of the swing rod rotating shaft 52, and the first positioning column 63 is parallel to the axial direction of the swing rod rotating shaft 52. As for the relation between the first positioning column 63 and the swing link rotating shaft 52, a cover body can be fixed at the end of the swing link rotating shaft 52, and the first positioning column 63 and the cover body are integrated; the root of the first positioning column 63 can also be designed to be a threaded structure, a threaded blind hole is formed in the position where the shaft end face of the swing rod rotating shaft 52 is connected with the first positioning column 63, and the first positioning column 63 is fixed on the shaft end face of the swing rod rotating shaft 52 in a threaded matching mode. One end of the first adjusting rod 61 is provided with a lantern ring structure 61-H, and the lantern ring structure 61-H is slidably sleeved on the first positioning column 63. The frame plate 1 is provided with a first partition rail 12 formed by protruding along the outer surface between the swing rod rotating shaft 52 and the first adjusting gear 62, the first partition rail 12 is provided with an opening 12-A allowing the first adjusting rod 61 to pass through, the width of the opening 12-A is slightly larger than the outer diameter of the first adjusting rod 61, the first partition rail 12 can play a limiting role when the swing rod rotating shaft 52 drives the first adjusting rod 61 to eccentrically rotate so as to prevent the first adjusting rod 61 from naturally sliding down under the action of gravity, and can play a role of supporting the first adjusting rod 61 after extending into the adjacent gear teeth of the first adjusting gear 62.
When the stop lever 53 is located in the middle of the adjustment groove 1-a, the first adjustment structure and the first matching structure, the second adjustment structure and the second matching structure are all combined with each other, that is, the first adjustment rod 61 is located between adjacent gear teeth extending into the first adjustment gear 62, when the stop lever 53 is pushed to separate the second adjustment structure and the second matching structure, the first adjustment rod 61 will continue to extend between adjacent gear teeth of the first adjustment gear 62, so if the first adjustment rod 61 is of a rigid structure, a certain margin needs to be reserved for the full height of the gear teeth (i.e., the radial length of the gear teeth) and the pitch of the gear teeth (i.e., the distance between adjacent gear teeth) of the first adjustment gear, so that the first adjustment rod 61 can continue to extend, but the full height of the gear teeth and the increase of the pitch of the gear teeth will cause corresponding deterioration of the structural strength of the gear teeth, and the distance between two adjacent gear teeth of the first adjustment rod 61 will also increase, the first adjusting rod 61 and the first adjusting gear 62 are more likely to be broken or deformed, and the service life is also shortened. In addition, in the process of pushing the gear lever 53, the first adjusting rod 61 extends into the gear lever, and the first adjusting gear 62 moves relative to the gear lever in a friction state to generate high damping, so that the gear lever 53 is pushed harder.
