Description

Technical Field

[0001] This utility model relates to the field of floodlight technology, specifically to a waterproof floodlight. Background Technology

[0002] Floodlights, as a type of high-brightness, long-distance lighting fixture, are widely used in outdoor buildings, stadiums, squares, parking lots, and other places. Because their working environment is mostly exposed outdoors and subject to harsh weather conditions such as rain and humid air, the waterproof performance of these fixtures is required to be high.

[0003] Existing waterproof floodlights typically achieve sealing by using an integral sealing ring between the housing and the protective glass plate. However, when disassembling, maintaining, or replacing the LED light panel, the entire protective plate and sealing structure must be removed. Repeated disassembly and reassembly can easily cause wear or even damage to the sealing ring, thereby reducing the overall waterproof rating of the light fixture. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a waterproof floodlight. It solves the problem that existing waterproof floodlights typically use an integral sealing ring between the housing and the protective glass plate to achieve sealing. However, when disassembling, maintaining, or replacing the LED light board, the entire protective plate and sealing structure need to be removed. Repeated disassembly and reassembly can easily cause wear or even damage to the sealing ring, thereby reducing the overall waterproof rating of the light fixture.

[0005] To achieve the above objectives, this utility model provides a waterproof floodlight, including a housing with a bracket rotatably connected to it. The housing has an internal cavity containing an LED light panel. One end of the housing has a detachable protective plate. A U-shaped frame is fixedly connected to the protective plate facing inwards, extending into the cavity and having a U-shaped groove on its outer circumference. An annular connecting groove is formed on the inner wall of the cavity corresponding to the position of the U-shaped frame. Four strip-shaped pressure plates are slidably disposed in the connecting groove: a first strip plate symmetrically arranged on the left and right sides, and a second strip plate symmetrically arranged on the front and rear sides. Each first strip plate is fixedly connected to a first sealing strip, and each second strip plate is fixedly connected to a second sealing strip. Both the first and second sealing strips can be inserted into the U-shaped groove and tightly contact its inner wall to achieve circumferential sealing.

[0006] Preferably, the system also includes four symmetrically arranged drive components. Each drive component includes a rotating plate. The housing has four symmetrically arranged circular openings, which are connected to the connecting groove through a connecting groove in the housing. Each rotating plate is rotatably disposed in a circular opening. Each rotating plate is fixedly connected to a threaded rod, and each threaded rod is threadedly connected to a threaded cylinder. The ends of the two threaded cylinders on the left and right sides that are away from the rotating plate are fixedly connected to a first strip plate, and the ends of the two threaded cylinders on the front and rear sides that are away from the rotating plate are fixedly connected to a second strip plate.

[0007] Preferably, each of the threaded cylinders is symmetrically fixedly connected with a sliding rod, and the opposite ends of the two corresponding sliding rods are slidably connected to the inner wall of the communicating groove to restrict the rotation of the threaded cylinder. Each rotating plate has a cross groove on its end face for cooperating with an external driving tool to rotate the threaded rod.

[0008] Preferably, each of the first strip plates is symmetrically fixedly connected with two sealing blocks, and each of the second strip plates is symmetrically provided with two insertion slots. Each sealing block is disposed in the insertion slot. The adjacent end faces of the first strip plate and the second strip plate are provided with mutually cooperating inclined guide surfaces so as to guide them to fit together during the pressing process.

[0009] Preferably, four ear plates are symmetrically fixedly connected to the protective plate, and the ear plates are installed on the housing by provided mounting bolts.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. By setting a spiral frame with a spiral groove on the protective plate, and configuring a sliding first strip plate and a second strip plate in the housing connection groove, and with the first sealing strip plate and the second sealing strip plate inserted into the spiral groove, a complete circumferential sealing structure is formed, which effectively prevents moisture from entering the internal cavity from the gap between the housing and the protective plate, and significantly improves the overall waterproof rating of the floodlight.

[0012] 2. With the set rotating plate, threaded rod and threaded cylinder, the first sealing strip plate and the second sealing strip plate can be precisely controlled to insert into the U-shaped groove. When it is necessary to maintain the internal light panel, the seal can be loosened and the protective plate can be removed simply by reversing the operation of the drive component. The whole process does not require the replacement of the seal, which is convenient and low cost. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-7This embodiment provides a waterproof floodlight, including a housing 1, with a bracket 101 rotatably connected to the housing 1. A cavity is formed inside the housing 1, and an LED light panel 102 is installed in the cavity. A detachable protective plate 2 is provided at one end of the housing 1. A U-shaped frame 201 is fixedly connected to the side of the protective plate 2 facing inwards from the housing. The U-shaped frame 201 extends into the cavity, and a U-shaped groove is formed on its outer circumference. An annular connecting groove is formed on the inner wall of the cavity of the housing 1 corresponding to the position of the U-shaped frame. Four strip-shaped pressure plates are slidably arranged in the connecting groove, namely, a first strip-shaped plate 301 symmetrically arranged on the left and right sides and a second strip-shaped plate 302 symmetrically arranged on the front and rear sides. Each first strip plate 301 is fixedly connected to a first sealing strip plate 303, and each second strip plate 302 is fixedly connected to a second sealing strip plate 304. Both the first sealing strip plate 303 and the second sealing strip plate 304 can be inserted into the U-shaped groove and make tight contact with its inner wall to achieve circumferential sealing. Each first strip plate 301 is symmetrically fixedly connected to two sealing blocks 305, and each second strip plate 302 is symmetrically provided with two insertion slots. Each sealing block 305 is set in the insertion slot. The adjacent end faces of the first strip plate 301 and the second strip plate 302 are provided with mutually cooperating inclined guide surfaces to guide them to fit together during the pressing process.

[0024] In summary, the improvement of this embodiment lies in:

[0025] By setting a spiral frame 201 with a spiral groove on the protective plate 2, and arranging a sliding first strip plate 301 and a second strip plate 302 in the connecting groove of the housing 1, and cooperating with the first sealing strip plate 303 and the second sealing strip plate 304 inserted into the spiral groove, a complete circumferential sealing structure is formed, which effectively prevents moisture from entering the internal cavity from the gap between the housing 1 and the protective plate 2, and significantly improves the overall waterproof level of the floodlight.

[0026] Based on the above, other structures also need to be disclosed in detail, such as:

[0027] Please see Figure 2 and Figure 4To drive the first strip plate 301 and the second strip plate 302 to move, four symmetrically arranged drive components are also included. Each drive component includes a rotating plate 401. Four circular openings are symmetrically provided on the housing 1, and these openings are connected to a connecting groove through a communicating groove in the housing 1. Each rotating plate 401 is rotatably disposed within a circular opening, and each rotating plate 401 is fixedly connected to a threaded rod 402. Each threaded rod 402 is threadedly connected to a threaded cylinder 403. The ends of the two threaded cylinders 403 on the left and right sides opposite to the rotating plate 401 are fixedly connected to the first strip plate 301, and the ends of the two threaded cylinders 403 on the front and rear sides opposite to the rotating plate 401 are fixedly connected to the second strip plate 302. Each threaded cylinder 403 is symmetrically fixedly connected to... The sliding rods 404, with their opposite ends slidably connected to the inner wall of the connecting groove, are used to restrict the rotation of the threaded cylinder 403. Each rotating plate 401 has a cross groove on its end face, which is used to cooperate with an external driving tool to rotate the threaded rod 402. When the tool is inserted into the cross groove of the rotating plate 401 and the rotating plate 401 is rotated, the threaded rod 402 is rotated. The threaded cylinder 403 is restricted from rotating by the sliding rods 404. The rotation of the threaded rod 402 causes the threaded cylinder 403 to move axially, thereby pushing the first strip plate 301 and the second strip plate 302 to slide in the connecting groove, so that the first sealing strip plate 303 and the second sealing strip plate 304 are inserted into the U-shaped groove of the U-shaped frame 201 and in close contact with the inner wall of the groove to form a circumferential seal.

[0028] Please see Figure 1 Four ear plates 202 are symmetrically fixedly connected to the protective plate 2. The ear plates 202 are installed on the housing 1 by the provided mounting bolts 2021, so as to realize the detachable fixing of the protective plate 2.

[0029] In summary, the working principle of this solution is as follows:

[0030] When the protective plate 2 is fixed to the housing 1 by the ear plate 202 and the mounting bolt 2021, the U-shaped frame 201 extends into the cavity of the housing 1. By operating the drive assembly, a tool is inserted into the cross groove of the rotating plate 401. Rotating the rotating plate 401 drives the threaded rod 402 to rotate. The threaded cylinder 403 is restricted from rotating by the sliding rod 404. The rotation of the threaded rod 402 causes the threaded cylinder 403 to move axially, thereby pushing the first strip plate 301 and the second strip plate 302 to slide in the connecting groove, so that the first sealing strip plate 303 and the second sealing strip plate 304 are inserted into the U-shaped groove of the U-shaped frame 201 and come into close contact with the inner wall of the groove to form a circumferential seal. The first strip plate 301 and the second strip plate 302 are pressed together by the inclined guide surface. The sealing block 305 is inserted into the insertion groove, which further enhances the sealing effect at the connection between the first sealing strip plate 303 and the second sealing strip plate 304. The whole process ensures the waterproof performance at the connection between the protective plate 2 and the housing 1 and prevents water from entering the internal LED light panel 102.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
