Abstract
The invention discloses a bulb fixing method of a medical universal cold light illuminating lamp and a structure thereof. After a bulb with a light condensation cup is mounted on a lamp base of an universal adjusting rod through a direct inserting mode, a compression spring is arranged on the light condensation cup; after a lamp cover is used for tightly pressing a compression spring in the bulb direction, the bulb is fixed to the universal adjusting rod; the bulb is more stable and not easy to displace by using elastic pressure of the compression spring; and the compression spring can be used for lengthening a heat conducting thread of the bulb to the lamp cover so as to prevent overheating of the lamp cover. The bulb fixing method not only can solve the bulb looseness problem of a medical cold light source, but also cannot cause overheating of the lamp cover while facilitating heat dissipation.
Description
Technical field
The present invention relates to a kind of bulb fixing means and structure thereof of medical universal cold light illuminating lamp, belong to medical illumination technical field.
Background technology
The Large-scale Medical Equipments such as the diagnosis and treat desk for specialty of auris, nose and pharyngolaryngology that hospital commonly uses, dental diagnostic platform all have the illness of cold light source illuminating lamp for helping doctor to observe inside, patient affected part, effectively improve the diagnosis and treatment degree of accuracy of doctor.In order to improve the convenience of use, existing Medical Cold Light Source illuminating lamp is all contained on a universal adjustment bar, and the direction of illumination of cold light source and position just can regulate by such doctor easily.And general Medical Cold Light Source bulb is all adopt plug-in type lamp holder (G), namely contact pin is used directly to be connected with lamp socket, and due to the power of bulb higher, lampshade generally all scalds user away from bulb to prevent lampshade overheated, carries out secondary fix so bulb is not arranged other structure.But the use of universal adjustment bar can make bulb constantly shake, result is exactly that the contact pin of bulb and the socket of lamp socket occur to loosen, the position of bulb on the one hand deflects and can cause light direction correction, affect illuminating effect, contact pin and the bad to such an extent as to contact that is lamp socket inside of jack contact can be caused on the other hand to burn out.In order to address these problems, some manufacturers can arrange buckle and be clamped by bulb on lampshade, but this mode is not only bad for bulb heat radiation, and lampshade temperature can be made too high, and buckle will be made to block bulb, and this has higher requirements to the structure precision of lampshade.
Summary of the invention
The object of the invention is to, a kind of bulb fixing means and structure thereof of medical universal cold light illuminating lamp is provided.It not only can solve the problem that Medical Cold Light Source bulb loosens, and lampshade can not be caused overheated while being conducive to heat radiation.
Technical scheme of the present invention: a kind of bulb fixing means of medical universal cold light illuminating lamp, be characterized in: after the bulb of band prefocus cup being installed to the lamp socket of universal adjustment bar by straight cutting mode, prefocus cup arranges a Compress Spring, and use lampshade to fix with universal adjustment bar after bulb orientation compresses Compress Spring, utilize the elastic pressure of Compress Spring that bulb more firmly, is not easily shifted, and Compress Spring can be utilized again to extend bulb to the heat conduction thread of lampshade, prevent lampshade overheated.
In the bulb fixing means of above-mentioned medical universal cold light illuminating lamp, described Compress Spring is volute spring, and one end that wherein diameter is little is fastened in the groove of prefocus cup end face, and one end that diameter is large is fastened in lampshade.
Realize the bulb fixed structure of the medical universal cold light illuminating lamp of preceding method, be characterized in: the lamp socket comprising universal adjustment boom end, lamp socket is provided with electrical outlet, the contact pin of cold light source bulb is to being inserted in electrical outlet, the dead ahead of cold light source bulb is provided with the lampshade be connected with universal adjustment bar, is provided with condensing glass in lampshade; Described cold light source bulb is integrated with prefocus cup, between the prefocus cup of condensing glass and cold light source bulb, is provided with Compress Spring.
In the bulb fixed structure of aforesaid medical universal cold light illuminating lamp, described Compress Spring is taper, and one end that wherein diameter is large is positioned at lampshade, and one end that diameter is little is fastened in the groove of prefocus cup end face.Can ensure that bright dipping is not blocked on the one hand, also increase the length of run of spring on the other hand.
Compared with prior art, the present invention utilizes prefocus cup on cold light source bulb as pedestal, between prefocus cup and lampshade, arrange a Compress Spring carries out resilient fixing to cold light source bulb, therefore no matter how universal adjustment bar moves, cold light source bulb can stably be fixed on lamp socket all the time, can avoid occurring that bright dipping is inaccurate, contact burns; And due to the actual length of run of Compress Spring comparatively large, even if so Compress Spring two contacts cold light source bulb and lampshade respectively, also can because heat conduction thread is oversize can not time lampshade overheated; On the other hand, Compress Spring also has larger surface area, contacts the effect in fact can playing fin with prefocus cup, and the heat that can be conducive in prefocus cup outwards distributes, can available protecting cold light source bulb.The present invention uses a simple Compress Spring, the ingenious multiple problems solving existing medical universal cold light illuminating lamp and exist, not only structure is simple, with low cost, and installation is also very convenient, without the need to doing any change to the structure of existing medical universal cold light illuminating lamp, very be conducive to, to the transformation and upgrade of existing medical universal cold light illuminating lamp, there is high benefit.
Accompanying drawing explanation
Fig. 1 is basic structure schematic diagram of the present invention.
Being labeled as in accompanying drawing: 1-lamp socket, 2-cold light source bulb, 3-lampshade, 4-condensing glass, 5-prefocus cup, 6-Compress Spring.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further illustrated, but not as the foundation limited the present invention.
Embodiment.A kind of bulb fixing means of medical universal cold light illuminating lamp: after the bulb of band prefocus cup being installed to the lamp socket of universal adjustment bar by straight cutting mode, prefocus cup arranges a Compress Spring, and use lampshade to fix with universal adjustment bar after bulb orientation compresses Compress Spring, utilize the elastic pressure of Compress Spring that bulb more firmly, is not easily shifted, and Compress Spring can be utilized again to extend bulb to the heat conduction thread of lampshade, prevent lampshade overheated.Described Compress Spring is volute spring, and one end that wherein diameter is little is fastened in the groove of prefocus cup end face, and one end that diameter is large is fastened in lampshade.
Realize the bulb fixed structure of the medical universal cold light illuminating lamp of preceding method, as shown in Figure 1: the lamp socket 1 comprising universal adjustment boom end, lamp socket 1 is provided with electrical outlet, the contact pin of cold light source bulb 2 is to being inserted in electrical outlet, the dead ahead of cold light source bulb 2 is provided with the lampshade 3 be connected with universal adjustment bar, is provided with condensing glass 4 in lampshade 3; Described cold light source bulb 2 is integrated with prefocus cup 5, between the prefocus cup 5 of condensing glass 4 and cold light source bulb 2, is provided with Compress Spring 6.Described Compress Spring 6 is taper, and one end that wherein diameter is large is positioned at lampshade, and one end that diameter is little is fastened in the groove of prefocus cup 5 end face.
