Description

Lamp shade positioning structure of signal lamp

Technical Field

The utility model relates to a technical field of signal lamp specifically is a lamp shade location structure of signal lamp.

Background

The signal lamp is different from a general lamp, and has particularity in installation and structure. First, structurally, the signal lamp includes a fixing cover, a lamp cover, and a lamp holder, the fixing cover being fixedly connected to the lamp holder and fixing the lamp cover between the fixing cover and the lamp holder. In terms of installation, the lampshade must ensure the installation precision, so that the orthogonality of the light distribution can be ensured.

The orthogonality of the light distribution is an important performance index for signal function lamps. Most of the existing signal lamps are installed by visual inspection during assembly, and a fine adjustment mode is adopted after assembly, so that the mode is long in time consumption, high in dependence degree on operation experience and large in assembly quality fluctuation; or adopt and be connected lamp shade and fixed lid, then with fixed lid again with the mode of lamp stand connection, this kind of mode is though simpler swift than last mode, but in fact, be the installation of lamp shade and fixed lid just has the error on the one hand, on the other hand is the installation of fixed lid and lamp stand has the error, the not up to standard condition of lamp shade installation just appears easily in the accumulation of two errors.

Generally speaking, with regard to the installation and positioning of the existing lampshade, the lampshade has the characteristics of low assembly efficiency and easy reworking, and during machining, the fixed cover and the lamp holder have deviation, so that the position of the lampshade is not accurate enough.

SUMMERY OF THE UTILITY MODEL

The utility model provides a lamp shade location structure of signal lamp, including fixed lid, lamp shade and lamp stand, the lamp shade with the relative surface of lamp stand on be provided with the locating pin respectively and with the draw-in groove of locating pin looks adaptation.

The utility model discloses a further set up to: the locating pin is rectangle, the length direction of locating pin with the radial unanimity of lamp shade.

The utility model discloses a further set up to: the length of the positioning pin is consistent with the annular width of the annular edge of the lampshade.

The utility model discloses a further set up to: the effective depth of the locating pin is greater than 1.5 mm.

The utility model discloses a further set up to: the effective depth of the locating pin is 2 mm.

The utility model discloses a further set up to: the locating pin is provided with at least two.

The utility model has the advantages of:

because the lamp shade is directly fixed a position through the locating pin with the lamp stand, guaranteed the accuracy of lamp shade position, then when fixed lid was installed, fixed lid had only played the effect of fixed lamp shade, did not exert an influence to the position of lamp shade.

Detailed Description

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.

Referring to fig. 1-3, the utility model discloses a 2 location structures of lamp shade of signal lamp, it is including fixed lid 1, lamp shade 2 and lamp stand, and fixed lid 1 passes through bolt fixed connection with the lamp stand, and lamp shade 2 is located between fixed lid 1 and the lamp stand, and fixed lid 1 presss from both sides lamp shade 2 with the lamp stand and presss from both sides the fastening.

And a positioning pin and a clamping groove matched with the positioning pin are respectively arranged on the opposite surfaces of the lampshade 2 and the lamp holder. The locating pin specifically is provided with two, locating pin and lamp shade 2 integrated into one piece. Through locating pin and draw-in groove, directly fix a position lamp shade 2 on the lamp stand, guaranteed the accuracy of 2 positions of lamp shade, fixed lid 1 has only played the effect of fixed lamp shade 2, does not exert an influence to the position of lamp shade 2.

The locating pin is rectangle, and the length direction of locating pin is unanimous with the radial of lamp shade 2 to the length of locating pin is unanimous with the annular width at the annular edge of lamp shade 2. The design is to increase the contact area of the positioning pin and the clamping groove, the positioning is firmer, and the stress condition of the root of the positioning pin is improved. The design of locating pin all adopts cylindrically usually, but the diameter of columniform locating pin must be restricted in the annular edge of lamp shade 2 to because lamp shade 2 is glass cast, so the locating pin also can not be too thin, just need thick that do under the condition of enough intensity is guaranteed to the locating pin, but under this condition, the stress condition of locating pin root will receive the influence of the annular edge of lamp shade 2, and the stress condition becomes more complicated, and stress can concentrate more in part. Therefore, the rectangular positioning pins are used, and the length of the positioning pins is substantially equal to the annular width of the annular edge of the lamp housing 2.

Additionally, the utility model discloses well locating pin's effective degree of depth is greater than 1.5mm, and the preferred is 2 mm. Just so can guarantee the abundant contact of locating pin and draw-in groove, and then just can guarantee the accuracy of lamp shade 2 and lamp stand location.
