Abstract
The invention discloses a kind of the light bulb fixing means and its mechanism of medical universal cold light illuminating lamp, after the light bulb with prefocus cup is installed to the lamp holder of universal adjustment bar by straight cutting mode, one compressed spring is set on prefocus cup, and it is fixed with universal adjustment bar after using lampshade compressing compressed spring to bulb orientation, so that light bulb is more consolidated using the elastic pressure of compressed spring, be not easy to shift, and compressed spring can be utilized to extend heat conduction thread of the light bulb to lampshade again, prevent lampshade from overheating.The present invention can not only solve the problems, such as that Medical Cold Light Source light bulb loosens, but also lampshade will not be caused to overheat while being conducive to heat dissipation.
Description
Technical field
The present invention relates to a kind of the light bulb fixing means and its structure of medical universal cold light illuminating lamp, belong to medical illumination skill
Art field.
Background technology
The Large-scale Medical Equipments such as the common diagnosis and treat desk for specialty of auris, nose and pharyngolaryngology of hospital, dental diagnostic platform all have cold light source illuminating lamp
It is used to help doctor and observes illness inside patient affected part, effectively improve the diagnosis and treatment accuracy of doctor.It is used to improve
Convenience, existing Medical Cold Light Source headlamp is incorporated on a universal adjustment bar, such doctor can easily by
The direction of illumination of cold light source and position are adjusted.And general Medical Cold Light Source light bulb is to use plug-in type lamp cap (G), i.e.,
It is directly connect with lamp holder using contact pin, and since the power of light bulb is higher, lampshade is generally all far from light bulb to prevent lampshade mistake
Heat and scald user, so being not provided with other structures on light bulb carries out secondary fixation.But the use of universal adjustment bar can make
Light bulb constantly shakes, and is as a result exactly that the contact pin of light bulb and the socket of lamp holder loosen, and the position of the light bulb of one side occurs partially
The change of team causes light direction to make corrections, and influences illuminating effect, and contact pin and jack contact on the other hand can be caused bad so that lamp holder
Internal contact is burnt out.In order to solve these problems, some manufacturers can be arranged on lampshade buckles light bulb clamping, but this
Mode can make lampshade temperature excessively high not only bad for bulb heat radiation, and to enable buckle block light bulb this to lampshade
Structure precision has higher requirements.
Invention content
The object of the present invention is to provide a kind of the light bulb fixing means and its structure of medical universal cold light illuminating lamp.It
It can not only solve the problems, such as that Medical Cold Light Source light bulb loosens, but also lampshade will not be caused to overheat while being conducive to heat dissipation.
Technical scheme of the present invention：A kind of light bulb fixing means of medical universal cold light illuminating lamp, its main feature is that：By straight
After light bulb with prefocus cup is installed to the lamp holder of universal adjustment bar by the mode of inserting, a compressed spring is set on prefocus cup, and
It is fixed with universal adjustment bar after compressing compressed spring to bulb orientation using lampshade, makes light bulb using the elastic pressure of compressed spring
It more consolidates, be not easy to shift, and compressed spring can be utilized to extend heat conduction thread of the light bulb to lampshade again, prevent lampshade mistake
Heat.
In the light bulb fixing means of above-mentioned medical universal cold light illuminating lamp, the compressed spring is volute spring, wherein
The small one end of diameter is fastened in the groove of prefocus cup end face, and the big one end of diameter is fastened in lampshade.
Realize the light bulb fixed structure of the medical universal cold light illuminating lamp of preceding method, its main feature is that：Including universal adjustment
The lamp holder of boom end, lamp holder be equipped with electrical outlet, the contact pin of cold light source light bulb to being inserted in electrical outlet, cold light source light bulb
Front is equipped with the lampshade being connect with universal adjustment bar, and condensing glass is equipped in lampshade；It is integrated on the cold light source light bulb poly-
Light cup is equipped with compressed spring between condensing glass and the prefocus cup of cold light source light bulb.
In the light bulb fixed structure of medical universal cold light illuminating lamp above-mentioned, the compressed spring is taper, wherein diameter
Big one end is located in lampshade, and the small one end of diameter is fastened in the groove of prefocus cup end face.On the one hand light extraction can be ensured not
It is blocked, on the other hand also increases the length of run of spring.
Compared with prior art, the present invention is using the prefocus cup on cold light source light bulb as pedestal, in prefocus cup and lampshade
Between one compressed spring of setting flexible fixation is carried out to cold light source light bulb, therefore no matter how universal adjustment bar moves,
Cold light source light bulb can be firmly secured on lamp holder always, can avoid the occurrence of that light extraction is inaccurate, contact is burnt；And due to compression
The practical length of run of spring is larger, so even if compressed spring both ends contact cold light source light bulb and lampshade respectively, as
Heat conduction thread it is too long without when lampshade overheat；On the other hand, compressed spring also has larger surface area, is contacted with prefocus cup
It can essentially play the role of cooling fin, the heat that can be conducive in prefocus cup distributes outward, can effectively protect cold light source
Light bulb.The present invention uses a simple compressed spring, it is ingenious solve it is more existing for existing medical universal cold light illuminating lamp
A problem is not only simple in structure, is of low cost, and installation is also extremely convenient, without to existing medical universal cold light illuminating lamp
Structure make any change, it is extremely advantageous in the transformation and upgrade to existing medical universal cold light illuminating lamp, there is high benefit.
Description of the drawings
Fig. 1 is the basic structure schematic diagram of the present invention.
Label in attached drawing be：1- lamp holders, 2- cold light source light bulbs, 3- lampshades, 4- condensing glass, 5- prefocus cups, 6- compressions
Spring.
Specific implementation mode
The present invention is further illustrated with reference to the accompanying drawings and examples, but be not intended as to the present invention limit according to
According to.
Embodiment.A kind of light bulb fixing means of medical universal cold light illuminating lamp：It will be with prefocus cup by straight cutting mode
After light bulb is installed to the lamp holder of universal adjustment bar, a compressed spring is set on prefocus cup, and uses lampshade to bulb orientation
It is fixed with universal adjustment bar after compressing compressed spring, so that light bulb is more consolidated using the elastic pressure of compressed spring, is not easy to shift,
And compressed spring can be utilized to extend heat conduction thread of the light bulb to lampshade again, prevent lampshade from overheating.The compressed spring is cone
The small one end of shape spring, wherein diameter is fastened in the groove of prefocus cup end face, and the big one end of diameter is fastened in lampshade.
