Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of lamps and lanterns, especially relates to a lamp sealing structure. BACKGROUND

[0002] In the field of lighting technology, the design of lamps and lanterns not only requires good lighting performance, but also needs to consider aesthetics, durability and safety, especially for those lamps and lanterns applied to outdoor environments or humid places, waterproof sealing performance is particularly important. In the design of traditional lamps and lanterns with glass cover plates, a sealing ring is generally added on the side of the glass plate to achieve waterproof effect. This design usually involves embedding a sealing ring in the gap between the glass plate and the lamp frame, and then applying pressure to the glass plate through a pressing frame to ensure that the sealing ring is compressed tightly, thereby preventing water from penetrating into the interior of the lamp.

[0003] However, although this structure improves the waterproof performance of the lamp to some extent, it still exposes several deficiencies in actual application. First, due to aging, wear and tear of the sealing ring material or improper operation during installation, the sealing effect is likely to gradually weaken over time, increasing the risk of water penetration. Second, the contact surface between the pressing frame and the glass plate is often difficult to be completely flat, with small gaps that may expand under temperature changes or vibration conditions, further reducing the reliability of waterproof sealing. Therefore, it is necessary to improve the existing waterproof sealing structure of lamps and lanterns with glass cover plates to improve their waterproof performance. SUMMARY

[0004] To solve the above problems, the purpose of the utility model is to provide a lamp sealing structure, the cover plate is inserted into the groove on the side, so that the sealing effect is better.

[0034] The utility model will be further explained in detail in combination with the drawings and specific embodiments. The advantages and features of the utility model will be more clear according to the following description. It should be noted that the drawings are all very simplified and all use non-precise ratios, only for the purpose of facilitating and clearly assisting the explanation of the embodiment of the utility model.

[0035] It should be noted that all directionality indications (such as up, down, left, right, front, back, etc.) in the embodiments of the utility model are only used to explain the relative position relationship, movement condition, etc. between components in a certain specific posture (as shown in the drawings), if the specific posture changes, the directionality indications will also change accordingly.

[0036] Referring to Figures 1 to 6 the core of the utility model is to provide a lamp sealing structure, which is arranged on a lamp shell 1 and includes a sealing groove 4, a sealing ring 6 and a pressing frame 10. The sealing groove 4 is arranged on the lamp shell 1 and surrounds a lens 2 on the lamp shell 1. The sealing ring 6 is arranged in the sealing groove 4. The pressing frame 10 is arranged on the side of the sealing ring 6 away from the lamp shell 1 and is used to press the sealing ring 6 tightly in the sealing groove 4.

[0037] The lamp shell 1 is provided with a cover plate 3, and the cover plate 3 is arranged on the lens 2. In this embodiment, the cover plate 3 is a glass plate, but in other embodiments, the cover plate 3 can also be an acrylic plate, etc. In this embodiment, no specific limitation is made.

[0038] The pressing frame 10 is detachably connected with the lamp shell 1. In this embodiment, the pressing frame 10 is fixedly connected with the lamp shell 1 by screws. Of course, other ways can also be used in other embodiments, and no specific limitation is made in this embodiment.

[0039] The sealing ring 6 is provided with a groove 7 on the inner side end facing the cover plate 3, and the cover plate 3 is inserted into the groove 7. Since the pressing frame 10 presses the sealing ring 6 tightly in the sealing groove 4, the sealing ring 6 is pressed by the pressing frame 10 and tends to deform, thereby forcing the groove wall and the groove bottom of the groove 7 to tightly adhere to the cover plate 3 to enhance the sealing effect. Since the cover plate 3 is inserted into the groove 7, the sealing effect is undoubtedly better than that of the cover plate 3 only with the side wall adhering to the sealing ring 6.

[0040] Further, the pressing frame 10 is provided with an insertion part 11 on the side facing the sealing ring 6, and the sealing ring 6 is provided with an insertion groove 8 corresponding to the insertion part 11, the insertion part 11 is inserted into the insertion groove 8, and the insertion part 11 is in interference fit with the insertion groove 8. The insertion part 11 presses the sealing ring 6 to tightly press the groove bottom of the groove 7 against the peripheral end surface of the cover plate 3. The insertion part 11 is inserted into the insertion groove 8 and is in interference fit with the groove wall of the insertion groove 8, which gives the sealing ring 6 a pressing force to the two sides to force the sealing ring 6 to deform to the two sides of the insertion groove 8, so that the groove bottom of the groove 7 is more tightly adhered to the cover plate 3, so that the sealing effect is better. If only the lower end surface of the pressing frame 10 presses the upper end surface of the sealing ring 6, the pressing frame 10 gives the sealing ring 6 a downward force, and the deformation amount of the sealing ring 6 to the two sides is small.

[0041] The width of the insertion groove 8 gradually decreases from the groove opening to the groove bottom, and the width of the insertion part 11 gradually decreases from the root to the head away from the pressing frame 10, so that the insertion part 11 is easily inserted into the insertion groove 8.

[0042] One side of the sealing groove 4 is provided with a stepped groove 5, and the sealing ring 6 is provided with a protrusion 9 corresponding to the stepped groove 5, and the protrusion 9 is arranged in the stepped groove 5. This design forms a complex waterproof route between the sealing ring 6 and the groove wall of the sealing groove 4, which can further play a waterproof role.

[0043] The stepped groove 5 is arranged on the side of the sealing groove 4 close to the cover plate 3, and the stepped groove 5 is arranged on the inner side groove edge surface of the sealing groove 4, the protrusion 9 is arranged on the side of the cover plate 3 facing the lamp housing 1, and the end surface of the protrusion 9 facing the cover plate 3 is flush with one side wall of the groove 7 and adheres to the cover plate 3. The adhesion of the protrusion 9 to the cover plate 3 increases the contact and adhesion area of the cover plate 3 and the sealing ring 6, further enhancing the waterproof effect. At the same time, the protrusion 9 is located on one side of the insertion groove 8, and when the insertion part 11 is inserted into the insertion groove 8 to press the sealing ring 6 to deform to the two sides, the protrusion 9 can be pressed to tightly adhere to the stepped groove 5 to enhance the sealing effect.

[0044] The inner side of the pressing frame 10 is provided with a turn-up 12, which is protrudingly arranged towards the cover plate 3 and is located at the inner side of the part of the sealing ring 6 protruding from the cover plate 3, and the turn-up 12 wraps the sealing ring 6 protruding from the cover plate 3 to shield and / or limit it. The turn-up 12 cooperates with the pressing frame 10 to wrap and shield the sealing ring 6 exposed above the cover plate 3, so that it is more beautiful, and the turn-up 12 can also play a certain waterproof role. Further, the turn-up 12 cooperates with the pressing frame 10 to wrap the sealing ring 6 exposed above the cover plate 3, and when the sealing ring 6 is deformed and extruded to the two sides, it is limited by the pressing frame 10 and the turn-up 12, so that the sealing ring 6 at this position can also better adhere to the upper end surface of the cover plate 3 to seal, so that the waterproof effect is better.

[0045] The embodiments of the utility model are described in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments. Even if various changes are made to the utility model, if the changes belong to the scope of the utility model claims and equivalent technologies, they still fall within the protection scope of the utility model.
