Embodiment Construction
[0039] The specific implementation manner of the present invention will be further described below in conjunction with the accompanying drawings.
[0040] like figure 1 , figure 2 and image 3As shown, the installation structure of the lamp head of the street lamp includes a sleeve 14 connected to the pole 12 of the lamp pole, and a frame 1 connected to the lamp head (the lamp head is not shown in the figure, the frame). The frame 1 is connected to the rear end of the lamp cap, the frame is a semi-enclosed structure, and the sleeve 14 is covered therein, and the frame and the shell of the lamp cap are integrally formed.
[0041] The sleeve 14 is set on the end of the light pole, and is fixed to the light pole by two screws 13 at the front end and the rear end respectively. Two short shafts 15 are arranged symmetrically on the left and right sides of the sleeve, and the axis of the short shafts 15 is perpendicular to the axis of the sleeve. An arched protrusion 8 is arrang...

The invention belongs to the technical field of street lamp mounting, and discloses a street lamp cap mounting structure with a pitch adjusting function. The mounting structure comprises a first mounting part and a second mounting part, wherein the first mounting part is connected with a lamp post supporting rod; the second mounting part is connected to the rear end of a lamp cap; two horizontal short shafts are symmetrically arranged on the two sides of the first mounting part; a cambered convex surface is arranged on the upper side of the first mounting part; the two sides of the second mounting part are connected with the two short shafts in a rotating manner respectively; a cambered concave surface which is matched with the cambered convex surface is arranged on the lower side of the top of the second mounting part; a propping screw capable of adjusting supporting height is arranged between the front end of the first mounting part and the front end of the second mounting part. Through the rotatable connection structure, adjustment of a pitch angle of the lamp cap is realized. The pitch angle adjustment of the lamp cap is guided through the cambered surface, so the stability and the adjustment accuracy are high, the accuracy requirement on the rotating shaft is low, and adjustment operation is also facilitated. The pitch angle adjustment operation is finished by adjusting the supporting height of the propping screw, so that the adjustment accuracy is reduced, and the adjustment accuracy is improved.
Description
technical field [0001] The invention belongs to the technical field of street lamp installation, and relates to an installation structure of a lamp head of a street lamp, in particular to an installation structure capable of adjusting the horizontal angle and the pitch angle of the lamp head of a street lamp. Background technique [0002] As the basic facilities of urban public lighting, street lamps are very important to the lighting performance of the road surface. The country has formulated the corresponding standard "CJJ 45-2006 Urban Road Lighting Design Standard", which regulates the height of street lamps from the road surface, the distance between light poles, and the road surface. The light shape of the lighting gives clear requirements. Since the light distribution design of the street lamp cap is based on the assumption that the lamp cap is at a certain distance from the road surface and at a certain angle, the light distribution calculation and analysis are compl...
