Description
Technical field
The utility model relates to a kind of stepless chair back adjusting device that is applied to comfortable chair.
Background technology
In the beauty parlour, the comfortable chair of use mostly is the structure at the stepless adjustable chair back of the body elevation angle at present, and the device of the adjusting chair back adopts vapour-pressure type or fluid pressure type more in this structure, and is especially in the majority with vapour-pressure type.
But no matter be air pressure or hydraulic pressure, it is when regulating the chair back, in the pneumatic cylinder (hydraulic cylinder) in this device is to be in all the time pressure condition is arranged, and seal adopts the rubber material more, then long-time pressurized, seal occurs aging easily and makes device gas leakage or leakage of oil, thereby loses the function that it regulates the chair back, has then reduced the service life of this hair dressers chair virtually.
The utility model content
The purpose of this utility model is to provide a kind of stepless chair back adjusting device that can effectively improve the hair dressers chair function of use.
For reaching above-mentioned purpose, solution of the present utility model is: stepless chair back adjusting device, mainly comprise control stick, chair back connecting plate, seat support connecting plate and adjusting rod, chair back connecting plate and seat support connecting plate are hinged, wherein also include pushing top spring, brake pad and cushion block; Be provided with below the seat support connecting plate between a disposal area; The front end of adjusting rod passes the rear wall between this disposal area, and passes the antetheca between the disposal area behind sliding sleeve pushing top spring, the brake pad more successively, and the below of the rear end of adjusting rod and chair back connecting plate is hinged; One end of control stick is set on the two side between the disposal area, is provided with a pulling block and places the front side of brake pad on this end of control stick; In the sidewall of corresponding pulling block, be provided with the cushion block of ejection brake pad one side between the disposal area.
The pulling block below of described control stick is connected with a back-moving spring, and the other end of back-moving spring is connected the rear of seat support connecting plate.
The front end of described adjusting rod is horizontally set with a spigot, is connected by buffer spring between spigot and the seat support.
Form " U " type groove that supplies adjusting rod to pass on the rear wall between described disposal area.
Rear wall between described disposal area is provided with a limited bolt.
After adopting said structure, because brake pad is under the effect of pushing top spring and cushion block, under its normal condition, brake pad and adjusting rod are an angle all the time, can't be in plumbness, so formation of angle of friction between brake pad and adjusting rod, adjusting rod just is in " self-locking " state; When desire is regulated chair back angle, pull control stick, make pulling block stir brake pad, when brake pad and adjusting rod were in plumbness, to the chair back application of force, then chair back connecting plate just can promote the relative seat support connecting plate motion of adjusting rod, with the elevation angle of the adjusting chair back.Mechanical chair back adjusting device like this, its abrasion is few, long service life then, and easy to maintenance, easily change.

The specific embodiment
As shown in Figure 1, stepless chair back adjusting device of the present utility model, it mainly comprises control stick 1, chair back connecting plate 2, seat support connecting plate 3 and adjusting rod 4, also includes pushing top spring 5, brake pad 6 and cushion block 7;
The top and the chair back of chair back connecting plate 2 are fixed together, and its below forms two articulated sections 21,22 respectively, and articulated section 21 is hinged with seat support connecting plate 3; Another articulated section 22 is hinged with adjusting rod 4;
The below of seat support connecting plate 3 relative seat supports is provided with between the disposal area that one or four retaining walls surround 31, its antetheca 311 is provided with the hole 3111 of ccontaining adjusting rod 4, its rear wall 312 is provided with ccontaining adjusting rod 4 " U " type groove 3121, also be provided with an adjustable limiting bolt 9, on its left and right sidewall 313,314, also be respectively arranged with the hole 3131,3141 of ccontaining control stick 1; Form at the rear of seat support connecting plate 3 and the hinged hinged seat 32 in chair back connecting plate 2 articulated sections 21, the left side of hinged seat 32 also is provided with the lug 33 that connects back-moving spring 8;
Adjusting rod 4 is the body of rod always, and its rear end forms and the hinged hinged seat 41 in chair back connecting plate 2 articulated sections 22;
The middle part of brake pad 6 is provided with the hole 61 of ccontaining adjusting rod 4.
As shown in Figure 2, when the utility model makes up, chair back connecting plate 2 is hinged with seat support connecting plate 3, adjusting rod 4 respectively, the front end of adjusting rod 4 passes " U " type groove 3121 on the rear wall 312, the hole 61 of sliding sleeve pushing top spring 5, brake pad 6 successively, pass again and be horizontally set with a spigot 42 behind the hole 3111 of antetheca 311 and fix, be connected by buffer spring 43 between spigot 42 and the seat support; Cushion block 7 places between brake pad 6 and the antetheca 311 and is fixed on the right side wall 314; One end of control stick 1 is also fixed by a spigot after stretching the hole 3131,3141 that places left and right sides sidewall 313,314, and the pulling block 12 on the control stick 1 places the place ahead of brake pad 6 simultaneously; Back-moving spring 8 connects two lugs 13,33 of control stick 1 and seat support connecting plate 3.Under this state, because the ejection effect of pushing top spring 5 and 7 pairs of brake pads 6 of cushion block makes brake pad 6 form an angle of friction with adjusting rod 4 all the time, and is in " self-locking " state (cooperating shown in Fig. 3,5).
As shown in Figure 4, when regulating chair back angle, pulling control stick 1 relative seat support clockwise rotates, then pulling block 12 just can be stirred brake pad 6 relative adjustment bars 4 and rotates counterclockwise, compress pushing top spring 5 simultaneously, when brake pad 6 is resisted against adjustable limiting bolt 9, it is with respect to adjusting rod 4 in vertical state the time, and then adjusting rod 4 just can overcome brake pad 6 to its " self-locking " function, because under the draw of buffer spring 43, to the chair back application of force, just can drive adjusting rod 4 and move relative to the seat support generation, when arriving the elevation angle of the required chair back, pine oil control stick 1, then under the effect of back-moving spring 8 and pushing top spring 5,6 pairs of adjusting rods 4 of brake pad are in one " self-locking " state again; When desire is recovered original chair back elevation angle, only need because the effect of pushing top spring 5 need not pulled control stick 1, the chair back to be recalled to original elevation angle state to the chair back top application of force, so, just realized the stepless regulatory function of the chair back.
