Description

Technical Field

[0001] The utility model relates to the technical field of street lamps, in particular to a waterproof street lamp which is easy to install and maintain. Background Art

[0002] Street lamps have strict requirements on waterproof performance, which must be above IP65. However, street lamps with good waterproof performance have complex structures and are difficult to disassemble and maintain at high altitudes.

[0003] Routine maintenance of street lamps focuses on the power supply of the lamps. Existing street lamps usually fix the inner cavity with screws, and corresponding tools need to be carried to carry out installation and maintenance work at high altitudes. Due to the complex structure of street lamps with good waterproof performance, the steps of removing the screws to expose the inner cavity are relatively complicated, which may lead to accidents at high altitudes. Utility Model Content

[0004] The main purpose of the utility model is to provide a waterproof street lamp which is easy to install and maintain, aiming to solve the technical problem that the street lamps with good waterproof performance in the prior art are not convenient to disassemble when maintaining the power supply of the lamps at high altitudes.

[0005] To achieve the above-mentioned purpose, the utility model proposes a waterproof street lamp which is easy to install and maintain, including a street lamp housing. A power cavity and a light source cavity are provided in the street lamp housing. The power cavity is used to place the lamp power supply, and the light source cavity is used to place the LED module. The power cavity is close to the installation end, and the light source cavity is far away from the installation end.

[0006] The street lamp housing comprises a rear cover plate located at the upper part of the power cavity, and the power cavity is snap-connected with the rear cover plate through a fixed snap-on structure to realize snap-on opening and closing.

[0007] The side of the rear cover plate close to the mounting end is the connecting side, and an elastic structure is arranged on the connecting side to be hinged to the street lamp housing. The opposite side or the side away from the mounting end is the buckling side of the rear cover plate, and the buckling side has a downwardly protruding undercut portion, which is buckled and connected to the fixed buckle structure. The elastic structure enables the rear cover plate to pop outward when the buckle constraint is lost.

[0008] The power cavity includes a power box, which includes a waterproof box, a bottom waterproof silicone ring is provided at the bottom of the waterproof box, and a top waterproof silicone ring is provided at the top of the waterproof box. The top of the waterproof box is in shape with the contact surface of the rear cover plate. When the rear cover plate is snap-connected with the fixed snap-in structure, the power box forms a sealed cavity.

[0009] With the waterproof street lamp of the utility model, when the staff is repairing the power supply, they release the buckle connection by controlling the fixed buckle structure. When the constraint is lost, the rear cover pops outward to expose the power cavity. After the repair is completed, the buckle connection is formed by pressing down the rear cover or controlling the fixed buckle structure, so that the power box forms a sealed cavity.

[0010] During high-altitude maintenance, the present invention has the following advantages. First, the rear cover is opened to mainly expose the power cavity, which is convenient for targeted maintenance of the power box; secondly, the fixed snap structure cooperates with the power box and the rear cover to achieve tool-free opening and closing, abandoning the opening and closing operation method of the prior art using screws, which greatly facilitates the installation and maintenance work of the operator and improves the safety of high-altitude operations; finally, since the fixed snap structure of the power cavity in the present application is far away from the installation end, the upward pop-up action of the rear cover is extremely convenient for high-altitude operations, and there is no need to set a handle on the rear cover, making the overall appearance more beautiful.

[0011] For the sake of convenience, street lamps in the prior art are mostly single-cavity designs, with the light source and power supply arranged in the same cavity. In the utility model, the power supply cavity is isolated from the light source cavity through the overall arrangement of the rear cover and the power box, thereby achieving a waterproof and dustproof structure, avoiding the negative impact of moisture and dust entering the power box on the lamp power supply, and the waterproof performance reaches IP66 or above; secondly, the single-cavity street lamps in the prior art generate a lot of heat due to the continuous use of the light source, which has a significant negative impact on the power supply. The lamp power supply in the utility model works in a relatively stable closed space, avoiding the direct impact of the heat of the light source, thereby increasing the service life and reducing the number of maintenance times.

[0012] Preferably, the elastic structure includes a second rotating shaft and a torsion spring, and the rear cover plate has a second rotating shaft hole for the second rotating shaft to pass through. After the second rotating shaft passes through the second rotating shaft hole and the torsion spring hole, it is installed in the second rotating shaft fixing seat on the street lamp housing. Under the rebound force of the torsion spring, the rear cover plate has a rotation tendency to pop outward around the second rotating shaft.

[0013] Specifically, the second shaft fixing seat includes a second shaft groove, a shaft pressure plate and a pressure plate fixing member. In a specific installation method, the second shaft passes through the second shaft hole and the torsion spring hole and is placed in the second shaft groove. The fixing screw locks the shaft pressure plate on the second shaft groove. The first shaft and the second shaft are preferably shaft rods.

[0014] Preferably, the fixing buckle structure comprises:

[0015] A first rotating shaft, the first rotating shaft is installed in a first rotating shaft fixing seat;

[0016] A fixing buckle, the fixing buckle comprising a first rotating shaft hole for the first rotating shaft to pass through, a clamping groove and a handle portion for clamping connection with the rear cover plate;

[0017] An elastic member, the elastic member is connected to the fixed buckle, and provides an elastic force so that the fixed buckle has a tendency to rotate along a fixed direction of the first rotating shaft, and the fixed direction is consistent with the direction when the card slot and the rear cover are buckled and connected;

[0018] The connection point between the elastic member and the fixed buckle is point A, the center of the first rotating shaft hole is point O, the center of gravity of the slot is point B, the center of gravity of the handle is point C, and point O is the fulcrum. The AO segment constitutes the first force arm, the OB segment constitutes the second force arm, and the OC segment constitutes the third force arm. Among them, the AO segment and the OB segment constitute the first lever for the buckle connection and maintaining the buckled state, and the AO segment and the OC segment constitute the second lever. After pushing the handle to overcome the resistance transmitted by the elastic member via the second lever, the slot is separated and the buckle connection state is released.

[0019] Further preferably, the fixed buckle structure is arranged in the middle part of the street lamp housing, and in the fixed buckle, the first rotating shaft hole is arranged at the bottom of the fixed buckle, the slot is arranged in the middle part of the fixed buckle, the handle is arranged at the top of the fixed buckle and protrudes from the back side of the street lamp housing, and the back side of the street lamp housing is provided with a movable groove to meet the moving space of the handle, the elastic part is a spring, which is connected to the bottom of the fixed buckle and provides an elastic force to push upward, so that the fixed buckle has a tendency to rotate counterclockwise along the first rotating shaft, and a bottom limit hole is arranged in the middle part of the street lamp housing for placing the spring.

[0020] Preferably, the waterproof street lamp further comprises a connecting cavity between the power cavity and the light source cavity, wherein the connecting cavity is provided with a waterproof circuit element connecting the lamp power supply and the LED module. According to the minimum horizontal height, the street lamp housing is set to H 电源腔 ≤H 连接腔 <H 光源腔 The street lamp housing is hollowed out at the bottom of the connecting cavity and the top of the light source cavity.

[0021] Specifically, the hollow setting at the top of the light source cavity is specifically a group of slender heat dissipation holes of different lengths distributed in a diamond array, and the hollow setting at the bottom of the connecting cavity is specifically a group of slender heat dissipation holes distributed in a barcode array with lengths regularly increasing and decreasing. It has a beautiful appearance and dust is not easy to enter.

[0022] Street lamps are used for a long time, and heat is easily accumulated in the light source cavity, which makes the temperature too high. Therefore, street lamps have high requirements for heat dissipation. The hollow setting of this solution helps the heat of the LED module to quickly dissipate from the top of the light source cavity or the bottom of the connecting cavity. Secondly, after the street lamp is horizontally installed on the street lamp pole, it will rain when it rains. Rainwater flows in through the hollow at the top of the light source cavity, and the water flows from high to low, and flows out from the hollow at the bottom of the connecting cavity. It is not easy to form water accumulation. When the street lamp is normally used after the rain, the heat generated by the power cavity quickly evaporates the residual water droplets on the inner wall of the street lamp shell into water vapor, which is dissipated from the hollow at the top of the light source cavity. Further preferably, on the bottom surface of the street lamp shell, the light source cavity is on the horizontal bottom surface at a high place, the power cavity is on the horizontal surface at a low place, and the connecting cavity is on the inclined surface connecting the two.

[0023] Preferably, the street lamp housing is provided with a circle of reinforcing ribs at the bottom of the power cavity, the bottom of the waterproof box is provided with a circle of silicone grooves corresponding to the position of the reinforcing ribs, the silicone grooves are used to accommodate the bottom waterproof silicone ring, the top waterproof silicone ring forms a wrap around the top of the waterproof box, and the side contact position of the rear cover is provided as a limiting rib. This solution has better waterproof sealing performance.

[0024] Preferably, the fixing buckle and the undercut portion are both provided with matching transition surfaces to facilitate smooth transition before buckle connection.

[0025] Preferably, a circuit groove is provided on the waterproof box for the waterproof circuit element to pass through, and the waterproof circuit element is fixed by the circuit fixing structure. Specifically, the waterproof circuit element includes a waterproof connector, a waterproof circuit, and the like.

[0026] Preferably, the LED module comprises: a heat sink, an LED light board and a lens, and the LED light board is sealed and arranged between the heat sink and the lens. BRIEF DESCRIPTION OF THE DRAWINGS
