Abstract

The utility model discloses an outer cover installing structure of a tubular lamp. An original outer cover of the tubular lamp with an anti-fog glass baffle is disassembled off by a rotating mode, the outer cover is completely separated from a fixed rack after disassembly, and thus, the outer cover has to be properly placed. The upper end surface of the outer cover of the utility model is connected with two symmetric V-shaped circlips with upward openings. The top end of each elastic arm is provided with a folding hook, the inner side of the convex edge of the fixed rack is provided with two bayonets corresponding to the positions of the V-shaped circlips, and elastic arms of the V-shaped circlips respectively passes through the bayonets. When the installing structure is applied to the tubular lamp, a user downward pulls the outer cover out from the fixed rack, an enough space for changing a lamp tube is obtained between the outer cover and the fixed rack, and also the outer cover is still suspended under the fixed rack and does not need to be disassembled off. Use is convenient. After the lamp tube is changed, the outer cover is upward pushed, and the outer cover can be positioned on the lower end surface of the fixed rack again. The outer cover installing structure of the utility model can be widely used for various anti-fog tubular lamps.

Description

A kind of outer cover attaching construction of Down lamp

Technical field

The utility model relates to a kind of lighting, particularly a kind of outer cover attaching construction that the light fixture of glass baffle plate is installed.

Background technology

At present, the end opening of general Down lamp all opens wide, but the structure of this open type in use inadequately safely, reliably, and improving constantly along with people's living standard, recognize that gradually the fluorescent tube in these Down lamps can exhale certain radius, influences the healthy of people.So, existing part Down lamp is by being equipped with the glass baffle plate to reach antifog at lower opening, radiation-resistant safe in utilization, reliable purpose, yet, these Down lamps mostly exist when changing fluorescent tube, the problem that the glass baffle plate is difficult to dismantle, and present on the market a kind of outer cover attaching construction of anti-mist barrel lamp, it comprises fixed mount and enclosing cover, fixed mount is used for such as terminal box, reflector, fluorescent tubes etc. are fixed on the ceiling, the central opening place of enclosing cover is equipped with the glass baffle plate, enclosing cover passes through the mounting means assembly of rotation screens on fixed mount, this enclosing cover can be pulled down by rotation, but owing to this enclosing cover separates with fixed mount when pulling down, so necessary placement is appropriate, otherwise can be from throwing in the air.

Summary of the invention

In order to address the above problem, the purpose of this utility model is to provide a kind of to be used reliably, the outer cover attaching construction of Down lamp easily.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of outer cover attaching construction of Down lamp, comprise enclosing cover fixed mount and enclosing cover, fixed mount is fixed on the installing hole of furred ceiling, be used for installing the connection terminal box, reflector, objects such as fluorescent tube, the convex edge is arranged on the fixed mount, the central opening place of enclosing cover is equipped with the glass baffle plate, stretch around the enclosing cover platform is arranged, it is characterized in that: the upper surface of enclosing cover is connected with the V-type jump ring that the opening of two symmetries makes progress, each V-type jump ring is made up of two elastic arms, there is the folding hook on the top of each elastic arm, and the inboard, convex edge of fixed mount is provided with two and the corresponding bayonet socket in V-type jump ring position, and the elastic arm of V-type jump ring passes bayonet socket respectively.

The beneficial effects of the utility model are: when this mounting structure specifically is applied on the Down lamp, fixed mount is fixed on the installing hole of furred ceiling, be used for installing objects such as connecting terminal box, reflector, fluorescent tube, when needing to change fluorescent tube, the user down pulls out enclosing cover from fixed mount, the elastic arm of V-type jump ring can overcome outside tension force from bayonet socket to downslide, when being hooked to, the folding of elastic arm reaches and when being stuck in bayonet socket, can there be enough spaces to change fluorescent tube, and enclosing cover still is hung in the below of fixed mount, need not to take off, extremely easy to use; When having changed fluorescent tube, enclosing cover is promoted toward the top, the V-type jump ring up moves simultaneously, deck roof around enclosing cover is below fixed mount, enclosing cover promptly reaches the top, and the elastic arm of V-type jump ring is stuck on the bayonet socket, and enclosing cover can not be to lower slider, make enclosing cover be positioned fixed mount below, simple in structure, use reliable, convenient.

The specific embodiment

With reference to Fig. 1～Fig. 3, a kind of outer cover attaching construction of Down lamp, comprise fixed mount 1 and enclosing cover 2, convex edge 3 is arranged on the fixed mount 1, the central opening place of enclosing cover 2 is equipped with glass baffle plate 4, stretch around the enclosing cover 2 platform 21 is arranged, the upper surface of enclosing cover 2 is connected with the V-type jump ring 5 that the opening of two symmetries makes progress, each V-type jump ring is made up of two elastic arms, there is folding hook 51 on the top of each elastic arm, 3 inboards, convex edge of fixed mount 1 are provided with two and the corresponding bayonet socket 6 in V-type jump ring 5 positions, and the elastic arm of V-type jump ring 5 passes bayonet socket 6 respectively.

As preferred implementation, the step 3 ' that the oriented central authorities in 3 tops, convex edge of fixed mount 1 stretch, bayonet socket 6 is located on the step 3 ', and it makes simple, reliable in structure.

For making elastic arm be easy to take out and can not get loose to the inside, the bayonet socket 6 that is located on the step 3 ' is the T type.

There is convex edge 7 on the top of enclosing cover 2, and V-type jump ring 5 is installed on the lateral wall of convex edge 7.

The outside, bottom of fixed mount 1 has shade 9, shade 9 to place in the platform 21 of enclosing cover 2.

Glass baffle plate 4 is fastened on the central opening place of enclosing cover 2.

In addition, with reference to Fig. 4, V-type jump ring 5 is converted into by an elastic metallic yarn, bottom coiled round, bending brace 8 is arranged on the enclosing cover 2, and bending brace 8 is fixed on by the riveted joint mode on the lateral wall of convex edge 7, and V-type jump ring 5 is actively socketed on the bending brace 8 by its cast bottom, after making enclosing cover down pull out can about skew, more sufficient operating space is arranged when make changing fluorescent tube.

With reference to Fig. 5, Fig. 6, when this mounting structure specifically is applied on the Down lamp, fixed mount 1 is fixed on the installing hole of furred ceiling, be used to be connected and installed objects such as frame 11, terminal box 12, reflector 13 and fluorescent tube 14, when needing to change fluorescent tube 14, the user down pulls out enclosing cover 2 from fixed mount 1, the elastic arm of V-type jump ring 5 can overcome outside tension force from bayonet socket 6 to downslide, when the folding hook 51 of elastic arm arrives and is stuck in bayonet socket 6, can there be enough spaces to change fluorescent tube 14, and enclosing cover 2 still is hung in the below of fixed mount 1, need not to take off, and is extremely easy to use; When having changed fluorescent tube 14, enclosing cover 2 is promoted toward the top, V-type jump ring 5 up moves simultaneously, withstand on the below of fixed mount 1 when the platform 21 of enclosing cover 2, enclosing cover 2 promptly reaches the top, and the elastic arm of V-type jump ring 5 is stuck on the bayonet socket 6, and enclosing cover 2 can not make enclosing cover 2 be positioned the fixed mount below to lower slider under the outside tension force effect of elastic arm.

Certainly, except the foregoing description, other equivalent technical solutions also should be within protection domain of the present utility model.
