Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of lamps and lanterns more specifically, relate to a lamp house and LED street lamp. BACKGROUND

[0002] A waterproof heat dissipation street lamp holder is disclosed in CN217763188U, wherein one side of the groove cover of the power supply mounting groove is connected to the back of the lamp house through a hinged manner, and the other side is fixed to the lamp house through a clamping hook. This structure design aims to facilitate the installation and maintenance of the power supply, while having certain waterproof and heat dissipation functions.

[0003] However, in the above-mentioned patent solution, especially after long-term use of the lamp holder, the hinge between the groove cover and the lamp house is prone to looseness.

[0043] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model. Example 1

[0044] like Figures 2-12 As shown, this embodiment discloses a lamp housing, comprising:

[0045] Base plate 1;

[0046] The flip cover 2 has a fixing ear 24 on one side, the fixing ear 24 has a rotating shaft 24a, and the axial cross section of the rotating shaft 24a is elliptical.

[0047] The pressure block 3 is fixedly connected to the base plate 1, and the rotating shaft 24a is rotatably embedded between the pressure block 3 and the base plate 1.

[0048] Furthermore, combined Figure 1 As shown in the figure, the front of the base plate 1 is the illumination surface, and the LED beads are located on the front of the base plate 1. A groove is provided on the back of the base plate 1, which includes a mounting groove 11 in the center and a guide groove 12 located around the outer periphery of the mounting groove 11. The mounting groove 11 and the guide groove 12 are separated by a first sealing surface 13, which protrudes from the bottom of the groove and is arranged in a ring around the outer periphery of the mounting groove 11. The bottom of the guide groove 12 has several guide holes 12a, with the guide holes 12a located at the lowest point of the guide groove 12, through which concentrated rainwater flows outward.

[0049] Furthermore, combined Figure 11As shown, in this embodiment, the flip cover 2 has a second sealing surface 21 and a second support column 22 on the side facing the base plate 1. When the flip cover 2 is in the closed position, the upper end of the first sealing surface 13 and the lower end of the second sealing surface 21 abut against each other to form a closed space, which is used to install electrical components such as batteries. A handle groove 23 is provided on one side of the flip cover 2 to facilitate the lifting of the flip cover 2 with fingers.

[0050] Furthermore, multiple first support columns 14 are provided in the mounting groove 11, with each first support column 14 corresponding to a second support column 22. When the flip cover 2 is in the closed position, the upper end of the first support column 14 and the lower end of the second support column 22 are pressed together, providing support for the flip cover 2.

[0051] Furthermore, a pair of fixing ears 24 are provided on one side of the flip cover 2, and a first semi-groove 15 is provided on the base plate 1 corresponding to the position of the rotating shaft 24a. A second semi-groove 31 is provided on the pressure block 3 corresponding to the position of the rotating shaft 24a. Combined Figure 12 As shown, in this embodiment, the pressure block 3 is provided with a connecting hole 32, and the pressure block 3 is fixedly installed on the base plate 1 by fasteners 4, wherein the fasteners 4 are selected from screws.

[0052] Furthermore, when installing the flip cover 2, it is necessary to first stand the flip cover 2 upright, that is, move the flip cover 2 to the open position, and place the pivot 24a on the fixing ear 24 against the first half-groove 15. Then close the pressure block 3, so that the second half-groove 31 on the pressure block 3 unfolds the upper part of the pivot 24a. Finally, the pressure block 3 is connected to the base plate 1 by the fastener 4.

[0053] Furthermore, combined Figures 6-11 As shown, in this embodiment, the fixing ear 24 is provided with a shielding part 25. When the flip cover 2 is in the closed position, the shielding part 25 covers the connecting hole 32 of the pressure block 3. When the flip cover 2 is in the open position, the connecting hole 32 is exposed to facilitate the installation or removal of the fastener 4.

[0054] Specifically, in combination Figures 5-8 As shown, in this embodiment, when the flip cover 2 is in the open position, the vertex of the short axis of the axial section of the rotating shaft 24a is in close contact with the pressure block 3. When the flip cover 2 is in the closed position, the vertex of the long axis of the axial section of the rotating shaft 24a is in close contact with the pressure block 3. That is, when the flip cover 2 is closed, the pressure block 3 and the larger semi-circular surface of the rotating shaft 24a are pressed together, increasing the downward pressure of the pressure block 3 on the rotating shaft 24a, so that the flip cover 2 remains in the closed position for a long time.

[0055] Furthermore, in this embodiment, when the flip cover 2 is in the closed state, the pressure block 3 is tightly abutted against the long axis of the rotating shaft 24a. The locking force of the fastener 4 on the pressure block 3 is transmitted through the long axis of the rotating shaft 24a, causing the rotating shaft 24a to fit tightly within the first semi-groove 15, reducing the vertical shaking of the flip cover 2. Similarly, when the flip cover 2 switches from the closed position to the open position, the downward pressure of the pressure block 3 on the rotating shaft 24a gradually decreases, and the opening of the flip cover 2 becomes increasingly smooth.

[0056] Furthermore, in some other embodiments, when the flip cover 2 is in the open position, the apex of the long axis of the axial section of the rotating shaft 24a is in close contact with the pressure block 3. When the flip cover 2 is in the closed position, the apex of the short axis of the axial section of the rotating shaft 24a is in close contact with the pressure block 3. That is, when the flip cover 2 is open, the pressure block 3 and the larger semi-circular surface of the rotating shaft 24a are tightly pressed together, increasing the downward pressure of the pressure block 3 on the rotating shaft 24a, allowing the flip cover 2 to remain in the open position for a longer period of time. When the flip cover 2 is in the open state, the pressure block 3 is tightly pressed against the long axis of the rotating shaft 24a. The locking force of the fastener 4 on the pressure block 3 is transmitted through the long axis of the rotating shaft 24a, causing the rotating shaft 24a to be tightly attached to the first semi-groove 15, reducing the vertical shaking of the flip cover 2. Similarly, when the flip cover 2 is switched from the open position to the closed position, the downward pressure of the pressure block 3 on the rotating shaft 24a gradually decreases, and the flip cover 2 closes more smoothly.
