Description

Technical Field

[0001] This utility model relates to a waterproof and dustproof LED flat ceiling light. Background Technology

[0002] With the continuous development of LED lighting technology, LED flat ceiling lights are widely used in indoor and outdoor lighting scenarios due to their advantages such as high efficiency and energy saving, long life and high brightness.

[0003] Existing LED flat ceiling lights typically rely on simple seals or housing structures, which can easily lead to damage or performance degradation due to moisture or dust intrusion in harsh environments (such as high humidity and dusty places).

[0004] Therefore, a waterproof and dustproof LED flat ceiling light is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a waterproof and dustproof LED flat ceiling light to solve the problem mentioned in the background art that existing LED flat ceiling lights usually rely on simple sealing parts or housing structures, which are easily damaged or have their performance degraded due to the intrusion of water vapor or dust in some harsh environments.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a waterproof and dustproof LED flat top light, including an LED flat top light body, a base provided on the upper part of the LED flat top light body, a sealing bushing connecting the LED flat top light body and the base, and an outer liner assembly provided on the upper part of the base.

[0007] The outer liner assembly is used to seal the sealing bushing to the outside of the LED flat-top lamp body and the base.

[0008] Preferably, the outer liner assembly includes an outer bushing that fits against the outer wall of the base, and a guide plate is provided around the inner wall of the outer bushing, with a threaded hole in the center of the guide plate.

[0009] Bolts are provided around the top of the base, and the lower part of the bolts has a thread-missing area. The bolts are connected to the LED flat-top light body in sequence through the base and threaded holes.

[0010] Preferably, the outer bushing is frustum-shaped, and the inner diameter of the outer bushing gradually decreases from top to bottom.

[0011] Preferably, an inner liner is provided on the upper outer wall side of the outer bushing, and a rubber protrusion is provided on the outer wall side of the inner liner.

[0012] Preferably, the outer wall of the base is provided with guide grooves around its perimeter for the movement of the guide plate.

[0013] Preferably, the upper periphery of the LED flat-top light body is provided with bolt holes for bolt connection.

[0014] Preferably, the sealing bushing has sealing grooves on both the upper and lower sides, and the sealing grooves cooperate with the base and the LED flat-top light body respectively, so that the sealing bushing connects the base and the LED flat-top light body.

[0015] Preferably, the sealing bushing has channels around its perimeter for bolts to pass through.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] The sealing bushing of this utility model, through the sealing grooves on the upper and lower sides, fits tightly with the base and the LED flat top light body to form an effective seal, preventing moisture and dust from entering.

[0018] The outer bushing is frustoconical in shape, with its inner diameter gradually decreasing from top to bottom. The outer bushing abuts against the interior of the sealing bushing, increasing the deformation of the sealing bushing and further enhancing the sealing effect. The inner liner and rubber protrusions on the outer bushing provide an additional sealing layer, ensuring that moisture and dust cannot enter the lamp's interior.

[0019] The outer liner assembly seals the sealing bushing to the outside of the LED flat-top light body and base, forming multiple layers of protection and significantly improving waterproof and dustproof performance.

[0020] Meanwhile, it is easy to operate. During installation, you only need to adjust the position of the outer bushing and turn the bolts to complete the waterproof and dustproof setting, which realizes quick fastening connection and simplifies the installation process.

[0029] To address the problem that existing LED flat-top lights, which typically rely on simple sealing components or housing structures, are prone to damage or performance degradation due to moisture or dust intrusion in harsh environments, this invention provides a waterproof and dustproof LED flat-top light. The technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0030] Please see Figure 1-7 This utility model provides a waterproof and dustproof LED flat top light, including an LED flat top light body 1, wherein bolt holes 101 for bolt 403 connection are provided around the upper part of the LED flat top light body 1.

[0031] The upper part of the LED flat top light body 1 is provided with a base 2, and the outer wall of the base 2 is provided with guide grooves 201 for the movement of the guide plate 402.

[0032] A sealing bushing 3 connects the LED flat-top lamp body 1 and the base 2. Sealing grooves 301 are provided on both the upper and lower sides of the sealing bushing 3, and these grooves 301 respectively cooperate with the base 2 and the LED flat-top lamp body 1 to connect them. Channels 302 for bolts 403 to pass through are provided around the perimeter of the sealing bushing 3.

[0033] An outer liner assembly 4 is provided on the upper part of the base 2. The outer liner assembly 4 includes an outer sleeve 401 that fits against the outer wall of the base 2. A guide plate 402 is provided around the inner wall of the outer sleeve 401. A threaded hole 4021 is opened in the middle of the guide plate 402. Bolts 403 are provided around the top of the base 2. The lower part of the bolts 403 has a thread-missing area. The bolts 403 are connected to the LED flat-top light body 1 through the base 2 and the threaded hole 4021 in sequence. The outer sleeve 401 is truncated pyramidal in shape, and the inner diameter of the outer sleeve 401 gradually decreases from top to bottom. An inner liner ring 404 is provided on the upper outer wall of the outer sleeve 401, and a rubber protrusion 4041 is provided on the outer wall of the inner liner ring 404.

[0034] The outer liner assembly 4 is used to seal the sealing bushing 3 on the outside of the LED flat top light body 1 and the base 2.

[0035] The working principle of the waterproof and dustproof LED flat top light provided by this utility model is as follows: During installation, the LED flat top light body 1, the sealing bushing 3 and the base 2 are connected in sequence, and then the bolt 403 is inserted through the base 2 and the sealing bushing 3 into the bolt hole 101 position of the LED flat top light body 1.

[0036] When the guide plate 402 passes through the bolt 403, the threaded area at the bottom of the bolt 403 is missing. The guide plate 402 moves upward so that the threaded hole 4021 of the guide plate 402 fits into the second thread of the bolt 403. Then the bolt 403 is rotated to control the guide plate 402 to fit against the lower side of the base 2.

[0037] Then rotate bolt 403 so that bolt 403 connects base 2 and seals bushing 3 against the side of LED flat top light body 1. Through the squeezing and bonding effect of bolt 403, LED flat top light body 1, seal bushing 3 and base 2 are tightly connected.

[0038] During the rotation of bolt 403, the second thread of bolt 403 engages with the threaded hole 4021 of guide plate 402, causing outer bushing 401 to gradually move downward. The inclined side of outer bushing 401 is inserted into the gap between base 2 and sealing bushing 3. Sealing bushing 3 is squeezed by outer bushing 401 and undergoes elastic deformation until sealing bushing 3 is squeezed and fitted onto the outer periphery of outer bushing 401, sealing the gap between base 2 and sealing bushing 3, thereby preventing external moisture and dust from entering the LED flat top light body 1 through the gap between base 2 and sealing bushing 3.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
