Description
Technical field
This utility model relates to the dental chair equipment technical field, the doublejointed headrest that particularly a kind of dental chair is used.
Background technology
At present, the headrest of dental chair generally adopts the simple joint structure, promptly headrest flexibly connects by a linkage and a retaining mechanism with the portion of extending upward of dental chair backrest, the swing angle of this articulation structure headrest adjustable, and then the angle of lying on the back of adjustment dental patient head, cooperate the treatment of doctor to the tooth of patient's mouth diverse location.But the size of dental chair is fixed at present, make according to general adult figure, but the patient of dentistry various figure from child to old man, from Ms to the disabled has, and the handicapped personage of of short and small stature or body uses the dental chair of present band simple joint headrest when receiving treatment; Head can't be gone up and can only lean against on the backrest by the pillow of decaptitating, and the angle of lying on the back of its head then can't be regulated, and makes troubles for the treatment of odontologist.In addition, the headrest of simple joint structure can only be around a hinge axis when regulating, and the mode of adjustment is more limited all the time.
Summary of the invention
The purpose of this utility model is to provide a kind of to be made of short and small stature or the handicapped personage of body can both use headrest effectively, cosily adjust the head angle of lying on the back, and the range of accommodation doublejointed headrest used of dental chair widely.
The technical solution that this utility model proposed is such: the doublejointed headrest that a kind of dental chair is used, comprise the backrest plate 9 and the head rest body that flexibly connect with the chair body, this head rest body is made up of medicated pillow shell 8 and medicated pillow PU spare 7, the stiff end of hypozygal support 2 is fixedlyed connected with backrest plate 9 one ends, also be provided with a fork 6, one end articulated section is hinged with the articulated section of hypozygal support 2 by hypozygal rotating shaft 3, the other end articulated section of this fork 6 is hinged with the articulated section of upper joint support 4 by upper joint rotating shaft 1, between upper joint articulated section and the hypozygal articulated section homonymy locking mechanism is housed, the stiff end of upper joint support 4 connects with described medicated pillow shell 8 and is connected.Fork articulated section, 6 two ends and body of rod inner chamber thereof are equipped with spring 10 and double end rack 11 respectively, and place in middle part, the articulated section dead slot of upper joint support 4 and hypozygal support 2, penetrate the upper joint rotating shaft 1 and the hypozygal rotating shaft 3 of band edge plate respectively, be separately fixed at by screw 5 on the side end face of upper joint support 4 articulated sections and hypozygal support 2 articulated sections, the end side of upper joint support 4 articulated sections and hypozygal support 2 articulated sections is fixed with upper joint gear member 13 and hypozygal gear member 12 respectively.
Compared with prior art, the utlity model has following beneficial effect:
Owing between dental chair and its headrest, adopted the doublejointed structure, can adjust the linkage of fixing two joints by pushing the double end rack, thereby make headrest can be fitted in the top of dental chair backrest downwards, under this state, can also adjust the pendulum angle of headrest, thereby also can cosily adjust the angle of lying on the back of head for of short and small stature or the handicapped personage of body can use headrest effectively.And the linkage in two joints can be more flexible, more various, and the amplitude of headrest being regulated adjustment is wider, makes patient's sitting posture more comfortable, and is more convenient when the dentist is treated.
Description of drawings
Fig. 1 is the STRUCTURE DECOMPOSITION figure of the doublejointed structure of a kind of dental chair headrest of this utility model.
Fig. 2 is the structural representation of the doublejointed structure of a kind of dental chair headrest of this utility model.
Fig. 3 is the working state schematic representation of the doublejointed structure of a kind of dental chair headrest of this utility model.
The specific embodiment
The doublejointed headrest features of with reference to the accompanying drawings a kind of dental chair of this utility model being used is described further below.
The doublejointed headrest features that a kind of dental chair of embodiment of this utility model is used is referring to Fig. 1-shown in Figure 3.The doublejointed structure of the dental chair headrest of present embodiment, under normal condition, spring 10 compresses double end rack 11, make double end rack 11 and upper joint gear member 13 and hypozygal gear member 12 remain engagement, the position of headrest has just fixed, if want to change the position of headrest, just press the middle part of double end rack 11, make double end rack 11 overcome spring 10 active force and in fork 6 bodies of rod intracavity move, make double end rack 11 with last, hypozygal gear member 13,12 break away from engagement, headrest just can turn to any adjustable angle, after finishing, adjustment unclamps the power that applies to double end rack 11 middle parts, under the elastic force effect of spring 10, double end rack 11 outwards resets with last, hypozygal gear member 13,12 are in engagement again.
In the process of adjusting, fork 6 can rotate around hypozygal rotating shaft 3, and upper joint support 4 also can rotate around upper joint rotating shaft 1.When the patient of normal stature uses, can be with the angle adjustment between upper joint support 4 and the fork 6 to approaching reduced state, with the extremely approaching state of spreading out of the angle adjustment between fork 6 and the hypozygal support 2, then be similar to the dental chair of the band simple joint structure headrest of present use simultaneously; When of short and small stature or suffer from disabled patient when using, can be with the angle adjustment between upper joint support 4 and the fork 6 to the approaching state of spreading out, simultaneously with the extremely approaching reduced state of the angle adjustment between fork 6 and the hypozygal support 2, then can make headrest place the top of dental chair backrest, order headrest can the support patient head, and the anglec of rotation that can adjust two joints plays and regulates headrest swing angle and then regulate the lie on the back function of angle of patient head.
And, this utility model is owing to adopt the doublejointed structure, headrest can be regulated by two rotating shafts 1,3 with respect to position, the angle of dental chair backrest, can only regulate by a rotating shaft compared with present simple joint structure, it is wider to have the amplitude of accommodation, and the assembled scheme of adjusting is more various, more flexible, more comfortable, treat advantage more easily.
