Description

Technical Field

[0001] The present application relates to the technical field of LED curing lamps, and in particular to an oral LED curing lamp. Background Art

[0002] In oral restoration and endodontics, light-curing resin is a commonly used material for modern dental cosmetic restoration. It is mainly composed of two materials: prepolymer and resin monomer. It contains active functional groups. Under ultraviolet light, it can form an insoluble coating through photosensitizers. It has the characteristics of high compressive strength and beautiful appearance. LED light curing lamp uses light-emitting diodes (silicon dioxide crystals emit blue light under the action of electric current) as light sources, emitting a certain wavelength (400nm-490nm) of light that is effective for photosensitive resins, irradiating the photosensitive resins and achieving curing effect, for dental restoration of teeth.

[0003] Existing light curing lamps usually adopt a rod-shaped structure, one end of which is a grip section and the other end is a curing lamp section. When in use, the staff holds the grip section, brings the curing lamp close to the tooth restoration position, and irradiates it. Usually, the curing time lasts for 1 minute to 10 minutes. During this process, the patient's mouth needs to be kept open at all times, and the medical staff also needs to remain relatively still, which is a certain burden for both parties. Therefore, in order to solve the above problems, the present application provides an oral LED curing lamp. Utility Model Content

[0004] In order to solve the problem that existing rod-shaped curing lamps are inconvenient to use, the present application provides an oral LED curing lamp.

[0005] The present application provides an oral LED curing light, comprising a lower card slot and an upper card slot elastically rotatably connected to each other, and a curing light structure composed of a power supply segment and a light-emitting segment, wherein an adjustment rod whose position can be fixed is movably connected to the lower card slot, and the adjustment rod is made of plastic metal, and at least one slider is arranged below the power supply segment, and the slider and the adjustment rod are interference fit.

[0006] Preferably, a through slot is provided in the middle of the slider, a spring sheet having one end fixedly connected to the slider is provided inside the through slot, a paddle is integrally formed at the free end of the spring sheet, and the spring sheet has the elastic force of the inner side of the inner slider channel.

[0007] Preferably, two pressing sections are integrally formed on the spring sheet, and both pressing sections face one side of the slider channel.

[0008] Preferably, a slide groove is welded on the upper end of the lower clamping groove.

[0009] Preferably, a sliding piece is welded to the end of the adjusting rod, and a nut sleeve is threadedly connected to one end of the adjusting rod close to the sliding piece.

[0010] Preferably, the ends of the upper card slot and the lower card slot are elastically rotatably connected through a torsion spring rotating shaft.

[0011] Preferably, silica gel sheets are embedded in the inner sides of the upper card slot and the lower card slot.

[0012] In summary, the present application includes the following beneficial technical effects:

[0013] By providing the lower card slot and the upper card slot that are elastically rotatably connected, the overall fixation of the device inside the oral cavity is realized, and at the same time, the soreness caused by the long-term opening of the patient's oral cavity can be reduced. The curing lamp that matches the adjusting rod with a certain plasticity can change its position more flexibly. Combining with the change of the overall position of the adjusting rod by the upper chute, different curing position requirements can be adapted. Compared with the prior art, the workload of the user can be effectively reduced, and the discomfort degree of the patient can be alleviated at the same time. Description of the Drawings

Detailed Description of the Embodiments

[0019] The following is a further detailed description of the present application in conjunction with the attached Figure 1 - Figure 4 Make a further detailed description of the present application.

[0020] Embodiment 1:

[0021] Refer to Figure 1 - Figure 4, an oral LED curing light, comprising a lower card slot 1 and an upper card slot 2 elastically rotatably connected to each other, the ends of the upper card slot 2 and the lower card slot 1 are elastically rotatably connected through a torsion spring shaft 4, and a curing light structure composed of a power supply section 7 and a light-emitting section 8, the power supply section 7 is provided with a rechargeable lithium battery, and the light-emitting section 8 is embedded with LED lamp beads of a suitable band, when in use, the curing light as a whole can be removed from a charging seat for independent use, and when not in use, it is placed on the charging seat for charging, the lower card slot 1 is movably connected with an adjusting rod 6 whose position can be fixed, the adjusting rod 6 is made of plastic metal, at least one slider 9 is provided below the power supply section 7, and the slider 9 and the adjusting rod 6 are interference fit.

[0022] A through slot 91 is provided in the middle of the slider 9, and a spring piece 92 having one end fixedly connected to the slider 9 is provided on the inner side of the through slot 91. A paddle 921 is integrally formed at the free end of the spring piece 92. The spring piece 92 has the elastic force of the inner side of the channel of the inner slider 9. Two downward pressing sections 922 are integrally formed on the spring piece 92. Both downward pressing sections 922 face one side of the channel of the slider 9. The two downward pressing sections 922 can be a V-shaped structure, and the combination of the two constitutes an M-shaped structure. The protrusions of the two contact with the outer wall of the adjusting rod 6 on the inner side of the channel of the slider 9, thereby increasing the friction force, thereby ensuring the stable position of the curing lamp.

[0023] A slide groove 5 is welded to the upper end of the lower slot 1, a slide plate 11 is welded to the end of the adjusting rod 6, and a nut sleeve 10 is threadedly connected to the end of the adjusting rod 6 close to the slide plate 11. The slide groove 5 is a symmetrically arranged L-shaped structure, and the slide plate 11 is slidably embedded in its inner side. The distance between the nut sleeve 10 and the slide plate 11 is adjusted to achieve the adjustment of the friction force between the slide plate 11, the nut sleeve 10 and the slide groove 5, thereby realizing the overall position adjustment, so that different fixed positions can be selected according to actual needs.

[0024] The inner sides of the upper card slot 2 and the lower card slot 1 are both embedded with a silicone sheet 3, and the silicone sheet 3 is used to improve the contact comfort between the upper card slot 2 and the lower card slot 1 and the teeth, thereby reducing the discomfort of wearing;

[0025] When the device is in use, first, according to the repair position, the adjusting rod 6 is reshaped so that it cooperates with the slider 9, and the curing lamp is set at a suitable position. Then, the upper slot 2 and the lower slot 1 are squeezed relative to each other so that they can be inserted into the patient's mouth, and the lower slot 1 and the upper slot 2 are respectively clamped to the patient's lower pressure and upper tooth positions. Under the action of the torsion spring shaft 4, the patient's oral cavity is supported to a certain extent, thereby reducing the discomfort caused by the patient's oral cavity being open for a long time. When the upper slot 2 and the lower slot 1 are clamped in place, the adjusting rod 6 can also be fine-tuned to a certain extent to make it better adapt to the position that needs to be cured.

[0026] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
