Abstract

The utility model relates to a road lamp shade which comprises a lamp shell with an upper cover. The road lamp shade is characterized in that a concave cavity is arranged on the bottom of the rear side of the lamp shell, and a lamp post connection seat sleeve is connected inside the concave cavity. By using the road lamp shade, the water can be prevented from infiltrating into the lamp shell through the connection seam between the lamp shell and the lamp post in the rainy days, and the external dust can be prevented from invading into the lamp shell to affect the insulativity. In addition, the road lamp shade can be installed conveniently for the lamp shell is not required to be placed slantways as installing.

Description

The street lamp lampshade

Technical field

The utility model relates to a kind of street lamp lampshade that hangs on the open-air lamp stand.

Background technology

The existing street lamp lampshade that hangs on the open-air lamp stand, normally link in use by the through hole of its lamp housing rear lateral portion and the lamp stand that stretches in the lamp housing, invade in order to prevent rainwater, no matter be perpendicular to lamp stand and still (seeing Fig. 9 and Fig. 8) be installed along the lamp stand horizontal direction, usually all need this street lamp lampshade certain angle of upwards steeving is installed the location, even like this, because the existence of lamp housing hole, extraneous dust and humid air still can be invaded in the lamp housing, thereby cause the circuit board short circuit that is installed on lamp housing inside.

Summary of the invention

The purpose of this utility model is to provide a kind of street lamp lampshade with good insulation performance performance and water resistance.

The utility model is to constitute like this, comprises the lamp housing with loam cake, and it is characterized in that: the lamp housing bottom rear is provided with cavity, is connected with lamp stand in the cavity and connects cover for seat.

The utility model is located at lamp housing rear side periphery separately owing to will connect cover for seat in order to the lamp stand that connects with lamp stand, lamp housing inner chamber and outside air are isolated fully, thereby both can effectively prevent when rainy day, water is from being penetrated in the lamp housing lamp housing and connecting the slit of lamp stand, thereby can prevent again that extraneous dust from invading influences insulating properties.In addition, during installation, lamp housing also needn't tilt to place, thereby it is more efficient and convenient that the user is installed.

The specific embodiment

With reference to Fig. 1-shown in Figure 7, the utility model comprises the lamp housing 2 with loam cake 1, it is characterized in that: the lamp housing bottom rear is provided with cavity 3, is connected with lamp stand in the cavity and connects cover for seat 4.

Connect the location that connects between cover for seat and the lamp stand for the ease of lamp stand, above-mentioned cavity is made of the seat box 3 with rear openings and open lower side that connects with the lamp housing bottom rear, it is the tubulose cover for seat of being located in the box die cavity 4 that described lamp stand connects cover for seat, described tubulose cover for seat runs through bolt assembly 5 with seat box one side wall through one and is connected and fixed, and is respectively equipped with between this tubulose cover for seat and the joining adjacent wall of seat box in order to adjustment and the face gear dish 6,7 (referring to illustrated in figures 1 and 2) that is meshing with each other and connects.During installation, adjust the relative angle of tubulose cover for seat and seat box after, make the face gear dish tight engagement of tubulose cover for seat and seat box after, by the through bolt assembly tubulose cover for seat and the locking of seat box are got final product.

In order to help the maintenance of operating personnel to the lamp interior structure, above-mentioned lampshade is had in order to the die cavity of light fixture to be installed by the front side, the lamp housing 2 that rear side is connected with a box constitutes with the loam cake 1 that is articulated on the lamp housing rear side end, described loam cake is hinged with a upper support arm 8 below the medial surface near its rear side end, this upper support arm is connected with another lower support arm 9 that the other end is articulated on the box upper side wall, wherein the point of attachment of upper support arm offers a sealing 10, the connection part of lower support arm is to have in order to encasing the U type portion 11 of upper support arm connection part from downside, on, the pin 12 of lower support arm connection part through running through U type portion and sealing be connected (referring to Fig. 1 and shown in Figure 3).During use, open loam cake after, two support arm linear states are opened, and make lower support arm upper end move to the upside of sealing with pin, can make loam cake keep open configuration.And will close loam cake the time, upwards lift loam cake slightly earlier, and make lower support arm upper end move to the downside of sealing with pin, the tie point of pushing two support arms downwards makes their disengaging linear states close loam cake.

In order further to strengthen the watertightness performance of this lamp housing, above-mentioned loam cake be respectively equipped with on the edge part connecting of lamp housing cooperatively interact in be equipped with sealant tape on, low groove, the lateral wall of described lamp housing is provided with in order to the lap buckle assembly 14 in the snapping loam cake lateral wall edge part groove 13, described lap buckle assembly comprises and fastens rigidity C type buckle 16 in the loam cake lateral wall edge part groove and two ends by its upper end 15 to be arranged in middle part in the lamp housing lateral wall bearing hole 17 respectively recessed and be the elasticity lattice framing 18 of swallow-tail form that the aperture road 19 of C type buckle on its bottom is hinged with the middle part of elasticity lattice framing; The outside of described C type buckle is provided with so that go up the toggle 20 of buckleing or threading off.When installing and using, the user can be in advance be arranged in the two ends of elasticity lattice framing respectively in the lamp housing lateral wall bearing hole, elbow with C type buckle upper end is buckled in the loam cake lateral wall edge part groove 13 then, and downward clinching plate bottom, uphold downwards at the middle part that makes the elasticity lattice framing be dove-tail form, when put to minimum point the lower end of C type buckle, its upper end elbow imposes on the tightening force maximum in the loam cake lateral wall edge part groove; When minimum point was put when leaning against the lamp housing lateral wall in the lower end of C type buckle, the middle part that the elasticity lattice framing is dove-tail form is retraction slightly upwards, acts on buckle (referring to Fig. 6, Fig. 7) thereby recover elastic force with less distortion.

In addition, connect being fixedly connected of cover for seat with lamp stand in order to help lamp stand, the screwed hole that above-mentioned lamp stand connects the cover for seat perisporium is provided with in order to lock the joint bolt 21 of lamp stand.

The utility model is not only simple in structure, easy to use, and insulation and waterproof and dustproof performance are good, have bigger application value.
