Detailed description of the invention
Further illustrate the utility model below in conjunction with Figure of description.
As shown in Fig. 2,3,4 and 5, backrest inclination slide mechanism comprises chair back assembly 2, chassis 5, spin locking handle 1 and slide assemblies.Chair back assembly 2 is welded to coordinate with slip lower cover 201 by backrest steel pipe and forms, and slip lower cover 201 is for fixing with slide assemblies.Chassis 5 bottom one sides are ramp structure, and the first chute 501 and the second chute 502 are set on this ramp structure.As preferred structure, the first chute 501 is two symmetrical chutes, and the second chute 502 is between two the first chutes 501.In the first chute 501, be equipped with slide assemblies, slide assemblies can slide in the first chute 501.Slide assemblies bottom is fixedly connected with by the screw a7 arranging with the slip lower cover 201 in chair back assembly 2, in the time that slide assemblies slides, just can drive chair back assembly 2 to slide like this.In order to realize the locking and unlocking of chair back assembly 2, on slip lower cover 201, be equipped with spin locking handle 1, spin locking handle 1 is threaded with slide assemblies after passing slip lower cover 201 and the second chute 502.As preferred structure, spin locking handle 1 is socketed plastic sheath 11 on the one end between chassis 5 and upper cover 4.Plastic sheath 11 mainly plays and steps up positioning action, realizes the object that slide assemblies can stop in the optional position of base 5.
The preferred structure of slide assemblies is the upper cover 4 that comprises slide block 3 and be fixedly connected with slide block 3, between slide block 3 and upper cover 4, fixes by the screw c13 arranging.Wherein slide block 3 is fixing with slip lower cover 201 after through the first chute 501, and spin locking handle 1 is through slip lower cover 201 and second chute 502 is rear is threaded with upper cover 4.Meanwhile, in order conveniently to meet the installation of slide block 3, the width of first chute 501 one end is arranged to be greater than to the width of slide block 3.
Between slide block 3 and chassis 5 lower surfaces, be equipped with the first nylon sliding sleeve 10, between upper cover 4 and chassis 5 upper surfaces, be equipped with the second nylon sliding sleeve 12.The effect of the setting of the first nylon sliding sleeve 10 and the second nylon sliding sleeve 12 is mainly: 1) reduce sliding friction and make the more smooth and easy minimizing abnormal sound that slides; 2) thus by mutually stepping up to lock the staying at random location of whole slide assemblies at chute; 3) slide assemblies is slided and plays the spacing effect in left and right on the chute on chassis 5.
In order to realize, the up-down adjustment of chair back assembly 2, is fixedly installed locating piece 8 by the screw b9 arranging on chassis 5, is fixedly installed gas bar lifting handle 6 on locating piece 8.
As shown in Figure 1, when use, when unclamping spin locking handle 1, chair back assembly 2 just can be along the chute sliding on chassis 5; In the time tightening spin locking handle 1, chair back assembly 2 just can stop in the optional position locking in 5 chutes of chassis.Thereby play adjusting back height and sit dark effect.
Shown in the above and figure is only preferred embodiment of the present utility model.It should be pointed out that for the person of ordinary skill of the art, not departing under the prerequisite of the utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
