Description
Technical field
The utility model belongs to field of sanitary equipment, the angle demodulator that particularly a kind of chair is foot-operated.
Background technology
Chair, as rest furniture conventional in people's daily life, occupies critical role in the life of people.Traditional chair does not have foot-operated, or has foot-operated but be foot-operatedly fixed on certain angle, and do not possess regulatory function, such design can not make everyone reach best rest effect.Application number is 201020273669.5 patent discloses and a kind ofly have flexible foot-operated chair, achieve foot-operated angular adjustment, solve the deficiency of conventional chair to a certain extent, but it connects comparatively complicated on the one hand, it keeps the fixing of foot-operated angle by the frictional force between each function steel disc on the other hand, this fixing stable not, when being subject to larger external force, easy generation between each function steel disc is slided, thus does not reach the effect of angular adjustment.
Applicant proposes a kind of imagination, and by arranging foot-operated in cushion front end, foot-operated front end is provided with leg rest cushion, and foot-operated rear end is connected with cushion bracket front end.This is foot-operated can spin upside down, in use, foot-operated turn to forward a certain angle place time, ride and fixed; In not used time, turn over foot-operated, make foot-operated gathering in.In order to adapt to different Man's Demands, will ride operationally, multiple gear will be set.Thus a kind of foot-operated angle regulator is provided, makes the key that the foot-operated this imagination that can be fixedly applicant in multiple angle can be achieved.
Utility model content
The purpose of this utility model is the angle demodulator providing a kind of chair foot-operated, its structure, connected mode are comparatively simple, can the foot-operated angle of free adjustment, and when ride be fixed on certain angle time, even if also can stationary state be kept when being subject to larger External Force Acting.
The technical scheme in the invention for solving the above technical problem is:
The angle demodulator that chair is foot-operated, comprise two holders being fixedly installed on chair seat bracket front end He being arranged on foot-operated rear end, described holder is hollow cylinder, holder one end open, and the other end is closed; The holder inside being arranged on foot-operated rear end is provided with spring and the second face gear, and described second face gear is fixed in holder inner circumferential, moves axially; Described angle demodulator also comprises gear plate, gear plate lower end is fixedly connected with the holder being fixedly installed on seat bracket front end by screw, gear plate upper end is fixed with the first face gear, described first end face gear face is provided with blind hole, through hole is provided with in the middle of blind hole, described angle demodulator also comprises the button that has wider base and narrower head, the base of button is arranged in blind hole, the head of button, through through hole, makes the base bottom of button and the end face of the second face gear when the first face gear and the second face gear are meshed offset; Described angle demodulator also comprises bearing pin, and bearing pin one end is fixed on the bottom surface of foot-operated holder, and the other end is successively through holder spring and second face gear of foot-operated rear end; First face gear and the second face gear cooperatively interact.When foot-operated remaining static, the first face gear and the second face gear engage mutually, now foot-operated fixing unadjustable.When needs adjustment angle, only need button press, thus drive the second face gear and spring movement, make the first face gear and the second face gear depart from fastening state, now, rotate foot-operated with the object reaching adjusting angle.When being adjusted to proper angle, release button, by the effect of spring-return power, the second face gear does return motion, makes to continue engaging between two face gears, thus realizes the object of angular adjustment.
As preferably, described gear plate and be provided with packing ring between the holder of foot-operated rear end.Owing to being provided with packing ring, making to obtain buffering between holder and gear plate, reduce the possibility of wearing and tearing between parts.
As preferably, described holder side is provided with the passage with holder plane perpendicular; Described second face gear sidewall is provided with the fin matched with this passage, and the diameter of the second face gear is suitable with the internal diameter of holder; Described fin snap-fits in passage, the second face gear is fixed in holder inner circumferential, moves axially.Circumference is arranged in connection between second face gear and holder fixing, moves axially, make the second face gear can be driven to rotate together when foot-operated rotation; When foot-operated static, release button, after the first face gear and the second face gear engage, rides and also can stablize state.
As preferably, described button head is the screw terminal of hexagonal configuration.When connecting bearing pin and button, button fixed by one end spanner, other end rotating pin.Button head being set to the screw terminal of hexagonal configuration, is in order to when fastening, can facilitate the fixing of button.
As preferably, described button head end face is provided with the groove chimeric with screwdriver.In like manner, it is also in order to time fastening that button head end face arranges the groove chimeric with screwdriver, is convenient to the fixing of button.
The utility model compared with prior art, has the following advantages and effect: the utility model is when foot-operated remaining static, and the first face gear and the second face gear engage mutually, now foot-operated fixing unadjustable.When needs adjustment angle, only need button press, thus drive the second face gear and spring movement, make the first face gear and the second face gear depart from fastening state, now, rotate foot-operated with the object reaching adjusting angle.When being adjusted to proper angle, release button, by the effect of spring-return power, the second face gear does return motion, makes to continue engaging between two face gears, thus realizes the object of angular adjustment.
