Description
Technical Field
The invention relates to a leisure chair, in particular to a damping adjusting mechanism for the leisure chair.
Background
When people are in indoor and outdoor leisure and entertainment, leisure chairs are frequently used; the back rest of a typical leisure chair may be inclined rearward to provide an optimal relaxed posture.
At present, the matching relation between the sizes of the human and machine of the backrest and the seat surface is not studied, and in the process of tilting, the backrest, particularly the waist rest, of the seat is separated from the waist of a human body, and a suspension gap is directly formed between the backrest and the waist rest, so that the seat loses the support on the waist of the human body in a tilting state, namely the 'waist running' which is commonly called by people, the human spine cannot be effectively supported, the health problem of sedentary sitting is caused, and the rest cannot be well relaxed; meanwhile, in the tilting process, the buttocks and the seat surface are relatively fixed, and the backrest is rubbed upwards relative to the back of a human body, so that discomfort of rubbing back and pulling clothes is caused, and an elegant feeling is also caused.
The backrest is hinged with the armrest frame, meanwhile, the backrest is hinged with the seat frame, the front end of the seat frame is high and low back, the front end of the seat frame is connected with the armrest frame in a sliding way through a sliding rod, the rear end of the seat frame can be lifted when the backrest is inclined, and meanwhile, the weight of a person is applied to the inclined seat frame to divide the weight of the person into downward pressure and backward reaction force; the force exerted by the human body on the seat frame can be fed back to the backrest through component force transmission, so that the backrest provides a support; the force components exerted on the sliding rod by people with different weights are different, so that the friction force and the backward reaction force between the sliding rod and the seat frame are also different; therefore, the pushing force fed back by the backrest is different when people with different weights recline the backrest; meanwhile, the structural limitation cannot meet the requirements of overweight people, and the friction force between the sliding rod and the seat frame cannot be adjusted, so that the backrest can not be matched with the friction force of the sliding rod, the use is not comfortable enough, and the friction force of the sliding rod needs to be adjusted by designing a damping adjusting mechanism, so that people with various weights can use the device comfortably.
Disclosure of Invention
In order to solve the technical problems, the invention aims to provide a damping adjusting mechanism for a leisure chair, which is used for holding a slide bar through a first clamping block and a second clamping block, and applying different pressures through the matching of an adjusting head and the second clamping block, so that the holding force applied to the slide bar is different, the friction force of the slide bar can be adjusted, the backward-lifting force of a backrest and the backward reaction force on the slide bar are balanced relatively, the backrest can be stopped at any angle, and the backrest is supported by a proper force, so that the comfort is improved; simultaneously, this damping adjustment mechanism is through applying different clamping effort to the slide bar in order to adjust the friction force of leisure chaise longue when falling to be fit for the crowd of different weight.
In order to achieve the above purpose, the present invention adopts the following technical scheme:
a damping adjustment mechanism for leisure chaise longue, damping adjustment mechanism include adjusting transmission pole, first clamp splice, second clamp splice, slide bar and play the fixed bolster of supporting role to damping adjustment mechanism and slide bar, first clamp splice, second clamp splice cover is located on the fixed bolster, the slide bar wears to locate between first clamp splice, the second clamp splice, and be equipped with on the relative medial surface of first clamp splice, second clamp splice with slide bar complex spout, adjusting transmission pole passes fixed bolster, first clamp splice, second clamp splice back and be connected with the adjustment head, adjustment head and adjusting transmission pole synchronous rotation, adjustment head rotates and then oppresses the second clamp splice to make first, the second clamp splice presss from both sides tight slide bar towards a direction, adjustment head rotates in the opposite direction then makes first, the second clamp splice loosen.
The interval between the first clamping block sliding groove and the second clamping block sliding groove, namely the tightness degree, determines the friction force of the sliding rod, and when the friction force is large enough, the sliding rod is locked, so that the sliding rod does not slide any more.
Preferably, the outer side surface of the second clamping block is provided with a positioning block matched with the adjusting head, the surface of the positioning block opposite to the adjusting head is provided with a plurality of positioning steps which are spirally distributed from shallow to deep, the adjusting head is provided with a spiral end surface, the spiral end surface is provided with a boss matched with the positioning steps, and the adjusting head rotates to enable the boss to be clamped into the corresponding positioning step. The boss is clamped into different positioning steps when the adjusting head rotates, so that the distance between the first clamping block and the second clamping block is changed, the clamping force of the first clamping block and the second clamping block on the sliding rod is changed, the positioning steps have a positioning effect, and the boss can be kept at the corresponding positions; in addition, the cooperation of boss and location step can increase and adjust the feel for form the auto-lock when two helicoids laminating.
Preferably, the fixing support and the sliding rod are vertically arranged, the fixing support is a hollow sleeve, the sleeve is divided into a thick pipe and a thin pipe, a step is formed at the junction of the thick pipe and the thin pipe, the first clamping block and the second clamping block are sleeved on the thin pipe, and the first clamping block is propped against the step. The fixed support and the sliding rod are vertically arranged, so that the first clamping block and the second clamping block are kept fixed in the circumferential direction of the fixed support, and the adjusting head can be clamped into different gears in an arbitrary rotation mode; the fixed support is divided into two sections of thickness, so that the first clamping block and the second clamping block are clamped at the step, and are fixed in the length direction of the fixed support.
Preferably, one ends of the first clamping block and the second clamping block are connected through screws, and a pressure spring is arranged between the other ends of the first clamping block and the second clamping block. The positioning block is clamped into the deeper positioning step under the rotation action of the adjusting head to inwards extrude the second clamping block, the second clamping block further extrudes the sliding rod, and when the adjusting head is loosened, namely the boss is clamped into the shallower positioning step, the second clamping block is reset under the elastic action of the pressure spring.
Preferably, the sliding rod is sleeved with a bushing, the bushing is clamped between the first clamping block and the second clamping block, and a notch which is arranged along the length direction of the bushing and penetrates through the whole bushing is formed in the outer wall of the bushing.
