Description

A kind of Down lamp

Technical field

Lighting lamp is the utility model is related to, particularly a kind of Down lamp.

Background technology

Down lamp is typically mounted on the periphery ceiling of bedroom, parlor, toilet.This lamp inside ceiling Tool, prevents take up space, can increase the soft atmosphere in space, has unique decorative effect.In order to attractive in appearance, Down lamp and other match somebody with somebody The surface of part typically can all plate coast of paint or process some decorative patterns.

The mode that existing Down lamp is fixed on the ceiling is usual as shown in figure 1, lamp body 3 ' leans on the elastic force and lamp of torsion spring 1 ' Ceiling 4 ' is clamped on the side 21 ' of prolonging of body fixture, to ensure that it is correct that it is installed to position when ceiling 4 ' is gone up.After installing, lamp body The side 2 ' of prolonging of fixture is combined together with ceiling 4 '.This erecting device is simple in construction, and installation is also easier.But Before installation, due to the elastic force of torsion spring 1 ', the torque arm 11 ' of torsion spring 1 ' can be pressed in the prolonging on side 21 ' of lamp body fixture, easily cause Down lamp prolongs the abrasion on side surface；During this Down lamp is sold, some buyers can be by the torsion of torsion spring 1 ' in order to understand product The pull-up of arm 11 ' is with the elastic force for torsion spring of having a try, and torque arm 11 ' can pound heavyly when torsion spring 1 ' rebounds in this case In prolonging on side 21 ' for lamp body fixture, therefore doing the Down lamp surface of meticulous landscaping treatment will also be weighed wounded.

Utility model content

In order to solve the above problems, the purpose of this utility model is the torque arm for providing a kind of torsion spring and lamp body fixture Prolong side and do not contact the Down lamp for without wearing its surface, influenceing outward appearance.

In order to solve the above technical problems, the technical solution adopted in the utility model is：

A kind of Down lamp, including lamp body fixture, lamp body and at least one torsion spring, the lamp body fixture include an annular Prolong side and a cylindrical shape fixed mount, the torsion spring is articulated with the top of the cylindrical shape fixed mount, the top of cylindrical shape fixed mount Be additionally provided with for the torque arm of the torsion spring abut against with so that the free end of torque arm and the annular prolong side between keep The boss in one gap.The material that lamp body fixture uses is generally plastics, and some require the light fixture of service life length or good heat dissipation Metal material can also be used.

Further, the support corresponding with the torsion spring is provided with the cylindrical shape fixed mount, the torsion spring is hinged In on support, while the boss is arranged at the one or both sides of the support.

Further, being offered on described boss can allow the torque arm of torsion spring to be overlapped on groove therein, and Down lamp is not yet pacified During dress, the torque arm of the torsion spring is just taken in a groove.So, packaging, transport and the mistake of sale before Down lamp installation Cheng Zhong, the torque arm of torsion spring fall into the movement in a groove, limiting torsion spring in axial direction so that total is more stable.

The quantity of the boss and torsion spring is generally 2 to 4, it is preferable that the quantity of the boss and torsion spring is 2.

Torsion spring typically has single two kinds of torsion spring and torsion spring, it is preferable that the torsion spring is torsion spring.Torsion spring typically has one U-shaped torque arm, the contact point of torque arm and ceiling is more when ceiling mounted, and installation is more firm.

As a kind of preferred embodiment of the utility model, the torque arm of the torsion spring is in direct rod shape.

As the utility model another kind preferred embodiment, the torque arm of the torsion spring is by the first flanging and the second flanging structure Into pole, the angle between first flanging and the second flanging is 120 ° to 170 °.Torque arm is standard for the torsion spring of straight-bar Part, it is being readily available on the market, cost is relatively low；, can be in torque arm and lamp body fixture when using torque arm as the torsion spring of pole Prolong back gauge it is enough in the case of, by the height reduction of boss, can so save the material of manufacture Down lamp, mitigate Down lamp Weight.

The beneficial effects of the utility model are：Boss is set in lamp body fixture to prop up because the utility model uses The torque arm of torsion spring so that the torque arm of torsion spring and the annular of lamp body fixture have gap between prolonging side, avoid torque arm from being pressed in lamp body The annular of fixture prolongs on side and destroys its surface, influences the attractive in appearance of Down lamp.

Embodiment

Reference picture 2 is to Fig. 6, and a kind of Down lamp in the utility model is by 3 three big portion of torsion spring 1, lamp body fixture 2 and lamp body It is grouped into.Lamp body fixture 2 prolongs the cylindrical shape fixed mount 22 of side 21 and one including an annular, and torsion spring 1 is articulated with the cylindrical shape The top of fixed mount 22, the top of cylindrical shape fixed mount 22 be additionally provided with for being abutted against with the torque arm 11 of the torsion spring 1 so that Torque arm 11 free end and the annular prolong the boss 221 that a gap 40 is kept between side 21.In addition, told boss also may be used To be arranged on the top that annular prolongs side 21.

Further, the support 222 corresponding with the torsion spring 1 is provided with cylindrical shape fixed mount 22, the torsion spring 1 is cut with scissors It is connected on support 222, while the boss 221 is arranged at the one or both sides of the support 222.

Further, having been opened up on described boss can allow the torque arm of torsion spring to be overlapped on groove 223 therein, and Down lamp is not yet During installation, the torque arm 11 of the torsion spring 1 is just ridden in groove 223.So, Down lamp installation before packaging, transport and During sale, the torque arm 11 of torsion spring 1 falls into the movement in a groove, limiting torsion spring 1 in axial direction so that total is more It is stable.

The quantity of boss 221 and torsion spring 1 is generally 2 to 4, and the quantity of preferable boss 221 and torsion spring 1 is 2, so If, the needs for installing fixed Down lamp can not only be met, meanwhile, the device of fixed torsion spring also just only needs 2, such Down lamp Relatively simple for structure, cost is relatively low.

Torsion spring 1 typically has single two kinds of torsion spring and torsion spring, it is preferable that the torsion spring 1 is torsion spring.Torsion spring typically has one The U-shaped torque arm of bar, the contact point of torque arm and ceiling is more when ceiling mounted, and installation is more firm.

The torque arm 11 of torsion spring 1 can make straight-bar, can also make what is be made up of the first flanging 111 and the second flanging 112 Pole, the angle between the flanging 112 of the first flanging 111 and second is 120 ° to 170 °, and it is suitable to can be made into circular arc etc. Shape.Torque arm 11 is standardized element for the torsion spring 1 of straight-bar, is being readily available on the market, cost is relatively low；Use torque arm 11 for During the torsion spring 1 being folded upward at, can the annular of torque arm 1 and lamp body fixture 2 prolong side 21 apart from enough in the case of, will be convex The height reduction of platform 221, the material of manufacture Down lamp can be so saved, mitigate the weight of Down lamp.

Preferred embodiments of the present utility model are the foregoing is only, as long as realizing the utility model with essentially identical means The technical scheme of purpose is belonged within the scope of protection of the utility model.
