Description

A kind of special headrest of dental chair

Technical field

The present invention relates to a kind of headrest more particularly to a kind of special headrests of dental chair.

Background technology

Dental chair is mainly the inspection and treatment for operation on oral cavity and mouth disease.Use electrodynamic type dentistry at present more Chair, 8 parts of primary structure point, complete machine nationality bottom plate are fixed on ground, and pass through stent and join the top of bottom plate and dental chair It connects, the action of dental chair is controlled by the control switch on the chair back, and operation principle is:Control switch starts motor operation and band Dynamic transmission mechanism work, makes dental chair corresponding component generate movement.According to treatment needs, manipulation and control switch knob, dental chair Up and down can be completed, bows, face upward the actions such as position and reset.

The shortcomings that existing product, is：The headrest diversification of forms of dental chair generally all has the function of adjusting the elevation angle； During use, since headrest is merely able to adjust the elevation angle, it is impossible to it is whole to adjust backward forward, it is reduced so as to cause patient comfort.

Invention content

In view of this, the object of the present invention is to provide a kind of special headrests of dental chair, can not only adjust the headrest elevation angle, also Headrest entirety can be adjusted backwards or forwards, improve the comfort level of patient.

The present invention solves above-mentioned technical problem by following technological means：

A kind of special headrest of dental chair, including headrest pedestal and headrest bolster, which is mounted on headrest pedestal, described Headrest pedestal is provided with mounting base, further includes adjustable plate and installing plate, described adjustable plate one end is hinged with mounting base, the other end It is hinged with installing plate, the installing plate is flexibly connected with backrest；Detent mechanism is provided in the adjustable plate, outside adjustable plate It is provided with adjusting knob.

What is reached has the technical effect that, the both ends of adjustable plate are hinged respectively with headrest and installing plate, forms two-part elevation angle tune Section can realize that entire headrest moves forwards or backwards by the way that the elevation angle at adjustable plate both ends is adjusted simultaneously, lead to simultaneously Height of headrest can be adjusted by crossing the installing plate of flexible connection.

Preferably, it is connected between the headrest bolster and headrest pedestal with thread gluing, thread gluing connection disassembling is convenient.

Specifically, the mounting base is arranged on headrest pedestal back, mounting base is connected with adjustable plate upper end by first rotating shaft It connects, first rotating shaft is fixed in mounting base.

Further, the adjustable plate lower end is connect by the second shaft with installing plate, and the second shaft is fixed on installing plate On, installing plate is inserted in the slot of backrest, and height can be adjusted in slot.

Preferably, the detent mechanism includes the first locking plate, the second locking plate and adjusting bolt, the first locking plate both ends point It is not provided with the first lock and the second lock, the second locking plate both ends are respectively arranged with third lock and the 4th lock；

First lock and third lock are symmetrically buckled in first rotating shaft, second lock and the symmetrical button of the 4th lock In the second shaft；

First locking plate and the second locking plate are provided with tapped through hole, and adjusting bolt connects first by tapped through hole Locking plate and the second locking plate, adjusting bolt one end are stretched out adjustable plate and are connect with adjusting knob.

First rotating shaft and the second shaft are separately fixed in mounting base and installing plate, as long as therefore restriction adjustable plate and first Relative motion between shaft and the second shaft can realize locating effect, be realized in this programme by a pair of of locking plate locked Function makes two locking plates cannot be with first close to locked first rotating shaft and the second shaft, adjustable plate by controlling to adjust bolt Shaft and the second shaft rotate, it is achieved thereby that positioning function.

Preferably, in order to make locked best results, the retaining ring formed after first lock and third lock fastening is less than The retaining ring formed after the diameter of first rotating shaft, second lock and the 4th lock fastening is less than the diameter of the second shaft.

Preferably, first lock, the second lock, third lock and the 4th lock are arc latches.

Preferably, first lock) and third lock is latched with the contact surface of first rotating shaft and second and the 4th lock Button and the contact surface of the second shaft are both provided with anti-skid chequer.

Preferably, the anti-skid chequer is zigzag, and the first rotating shaft and the second shaft are also equipped with corresponding zigzag Anti-skid chequer.

Beneficial effects of the present invention：It compares with traditional dental chair headrest, the headrest in this programme is cut with scissors using two-part Binding structure, it is achieved thereby that headrest is whole forward backward and the elevation angle is adjusted, solve existing product can only adjust the elevation angle cannot The problem of front and rear adjusting；While headrest can adjust height, finally cause patient's with being also to be flexibly connected between backrest Comfort level, which obtains maximizing, to be met.
