Description

Technical Field

[0001] This utility model relates to the field of lighting fixture technology, specifically to a lighting fixture with a sensor. Background Technology

[0002] When workers are conducting surveys or construction in relatively enclosed spaces, they need lighting fixtures for auxiliary illumination. In order to detect whether there are people in these relatively enclosed work environments, or to detect the air and terrain in the area, infrared sensors can be added to the lighting fixtures to make them more effective.

[0003] According to a public notice of a lighting lamp with an infrared sensor (publication number: CN219735249U), in the above application, the infrared sensor is set outside the lamp housing through a connector, so that the infrared sensor and the lighting component are spaced apart from each other, thereby reducing the possibility that the lighting component will generate heat during the light emission process and affect the detection of the infrared sensor, thus enabling the infrared sensor and the lighting lamp to work normally after being combined.

[0004] However, in actual use, the infrared sensor's position is fixed by the protective casing, making it impossible to change. In narrow areas, the externally mounted infrared sensor increases the size of the lamp, making both the lamp and the infrared sensor susceptible to collisions and damage. Therefore, we propose a lighting fixture with a built-in sensor. Utility Model Content

[0005] The purpose of this invention is to provide a lighting fixture with a sensor to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lighting fixture with a sensor, comprising a fixed cylinder, a diffuser plate fixedly connected to the outer wall of the fixed cylinder, a lamp tube fixedly connected to the inner wall of the diffuser plate, a pull plate rotatably connected to the outer wall of the fixed cylinder, a gear fixedly connected to one end of the fixed cylinder near the pull plate, a locking block slidably connected to the inner wall of the pull plate, a spring fixedly connected to one end of the locking block away from the gear, and a protective component provided inside the fixed cylinder, the protective component comprising:

[0007] A gas spring rod is fixedly connected to the lower outer wall of the fixed cylinder. A protective sleeve is fixedly connected to the output end of the gas spring rod. A turntable is rotatably connected to the end of the protective sleeve away from the diffuser plate. A limit ring is fixedly connected to the end of the turntable close to the protective sleeve.

[0008] The protective sleeve has a limiting groove on its inner wall. A threaded rod is fixedly connected to the inner wall of the turntable. A sliding sleeve is threadedly connected to the outer wall of the threaded rod. An infrared sensor is fixedly connected to the end of the sliding sleeve away from the threaded rod.

[0009] Preferably, the protective cover has a closure assembly inside, the closure assembly includes a cover plate, the cover plate is rotatably connected to the outer wall of the protective cover, a buckle plate is fixedly connected to the outer wall of the cover plate, a lever plate is fixedly connected to the outer wall of the buckle plate, a slot is opened on the outer wall of the buckle plate, and a locking block is fixedly connected to the outer wall of the protective cover, so that rotating the cover plate can block the opening of the protective cover.

[0010] Preferably, the buckle plate is composed of a flexible plate, the slot engages with the locking block, the size of the cover plate is the same as the opening size of the protective sleeve, and the outer wall of the cover plate fits against the outer wall of the protective sleeve, so that after rotating the cover plate until the locking block is engaged in the slot, the cover plate can always remain closed.

[0011] Preferably, a limiting strip is fixedly connected to the outer wall of the infrared sensor, and a sliding groove matching the limiting strip is opened on the inner wall of the protective sleeve. The limiting strip and the inner wall of the sliding groove are slidably connected, so that when the rotating turntable causes the threaded rod to rotate, the sliding sleeve drives the infrared sensor to move smoothly within the protective sleeve through the cooperation of the limiting strip and the sliding groove, so that the infrared sensor can extend out of the protective sleeve.

[0012] Preferably, a protruding ring is fixedly connected to the end of the limiting ring away from the turntable, and a protruding groove is formed on the outer wall of the limiting groove. The protruding ring is rotatably connected to the inner wall of the protruding groove, so that the turntable will not come out of the protective sleeve when it rotates, and the threaded rod can be kept rotating on the inner wall of the protective sleeve. The inner wall of the protective sleeve is in contact with the outer wall of the infrared sensor, and the infrared sensor is slidably connected to the inner wall of the protective sleeve. The length of the protective sleeve is consistent with the sum of the length of the infrared sensor and the length of the sliding sleeve, so that when the infrared sensor is not needed, the infrared sensor can be completely retracted into the protective sleeve, so that the protective sleeve can protect the infrared sensor and make the infrared sensor less prone to damage.

[0013] Preferably, the inner wall of the protective sleeve is fitted to the outer wall of the infrared sensor, the infrared sensor is slidably connected to the inner wall of the protective sleeve, and the length of the protective sleeve is the same as the sum of the length of the infrared sensor and the length of the sliding sleeve, so that when the infrared sensor is not needed, the infrared sensor can be completely retracted into the protective sleeve, thus protecting the infrared sensor.

[0014] Preferably, the locking block engages with the gear, and the end of the locking block away from the spring is fixedly connected to the inner wall of the pull plate. When the fixed cylinder is rotated, the fixed cylinder drives the gear to rotate inside the pull plate, so that the locking block can fix the rotated gear, thereby fixing the position of the fixed cylinder.

[0015] Compared with the prior art, this utility model provides a lighting fixture with a sensor, which has the following beneficial effects:

[0016] 1. This lighting fixture with sensor rotates a turntable to rotate a threaded rod, which in turn causes a sliding sleeve to move an infrared sensor. At this time, the infrared sensor moves smoothly within the protective sleeve through the cooperation of a limit strip and a sliding groove, allowing the infrared sensor to extend out of the protective sleeve. In addition, the gas spring rod changes the position of the infrared sensor, enabling the lighting fixture to adapt to different environmental conditions and preventing the infrared sensor from being hit.

[0017] 2. This lighting fixture with sensor can completely retract the infrared sensor into the protective cover when it is not in use. When the cover is rotated, the locking block is engaged in the slot, and the cover can always remain closed, so that the infrared sensor is not easily contaminated with dust when not in use. To unlock, simply move the lever to separate the locking block from the slot, and the cover can be rotated again. Attached Figure Description

[0023] like Figures 1-4As shown, this utility model provides a technical solution: a lighting fixture with a sensor, including a fixed cylinder 1, a diffuser plate 2 fixedly connected to the outer wall of the fixed cylinder 1, a lamp tube 3 fixedly connected to the inner wall of the diffuser plate 2, a pull plate 4 rotatably connected to the outer wall of the fixed cylinder 1, a gear 5 fixedly connected to one end of the fixed cylinder 1 near the pull plate 4, a locking block 6 slidably connected to the inner wall of the pull plate 4, a spring 7 fixedly connected to one end of the locking block 6 away from the gear 5, and a protective component 8 provided inside the fixed cylinder 1, the protective component 8 including a gas spring rod 81, a protective sleeve 82, a turntable 83, a limiting ring 84, a limiting groove 85, a threaded rod 86, a sliding sleeve 87, and an infrared sensor 88.

[0024] In one embodiment of this utility model, a gas spring rod 81 is fixedly connected to the lower outer wall of the fixed cylinder 1, a protective sleeve 82 is fixedly connected to the output end of the gas spring rod 81, a turntable 83 is rotatably connected to the end of the protective sleeve 82 away from the diffuser plate 2, and a limit ring 84 is fixedly connected to the end of the turntable 83 near the protective sleeve 82.

[0025] In one embodiment of this utility model, a limiting groove 85 is formed on the inner wall of the protective sleeve 82, a threaded rod 86 is fixedly connected to the inner wall of the turntable 83, a sliding sleeve 87 is threadedly connected to the outer wall of the threaded rod 86, and an infrared sensor 88 is fixedly connected to the end of the sliding sleeve 87 away from the threaded rod 86.

[0026] In addition, the protective cover 82 is provided with a closing component 9 inside. The closing component 9 includes a cover plate 91, which is rotatably connected to the outer wall of the protective cover 82. A buckle plate 92 is fixedly connected to the outer wall of the cover plate 91, and a lever plate 94 is fixedly connected to the outer wall of the buckle plate 92. A slot 93 is opened on the outer wall of the buckle plate 92, and a locking block 95 is fixedly connected to the outer wall of the protective cover 82. This allows the rotating cover plate 91 to block the opening of the protective cover 82, making it less likely for the infrared sensor 88 to get dusty when not in use, and making the infrared sensor 88 more convenient to use.

[0027] In an embodiment of this utility model, the buckle plate 92 is composed of a flexible plate, the slot 93 is engaged with the locking block 95, the size of the cover plate 91 is the same as the opening size of the protective sleeve 82, and the outer wall of the cover plate 91 fits against the outer wall of the protective sleeve 82, so that after rotating the cover plate 91 until the locking block 95 is engaged in the slot 93, the cover plate 91 can always remain closed, so that the infrared sensor 88 is not easily contaminated with dust when it is inside the protective sleeve 82.

[0028] In an embodiment of this utility model, a limiting strip is fixedly connected to the outer wall of the infrared sensor 88, and a sliding groove matching the limiting strip is opened on the inner wall of the protective sleeve 82. The limiting strip and the inner wall of the sliding groove are slidably connected, so that when the rotating turntable 83 rotates the threaded rod 86, the sliding sleeve 87 drives the infrared sensor 88 to move smoothly within the protective sleeve 82 through the cooperation of the limiting strip and the sliding groove, so that the infrared sensor 88 can extend out of the protective sleeve 82. Then, in conjunction with the gas spring rod 81, the position of the infrared sensor 88 is changed to adapt to environments with different widths.

[0029] In an embodiment of this utility model, a protruding ring is fixedly connected to the end of the limiting ring 84 away from the turntable 83, and a protruding groove is provided on the outer wall of the limiting groove 85. The protruding ring is rotatably connected to the inner wall of the protruding groove, so that the turntable 83 will not come out of the protective sleeve 82 when it rotates, so that the threaded rod 86 can be kept rotating on the inner wall of the protective sleeve 82, and so that the rotation of the threaded rod 86 can drive the infrared sensor 88 to move through the sliding sleeve 87.

[0030] In an embodiment of this utility model, the inner wall of the protective sleeve 82 is fitted to the outer wall of the infrared sensor 88, the infrared sensor 88 is slidably connected to the inner wall of the protective sleeve 82, and the length of the protective sleeve 82 is consistent with the sum of the length of the infrared sensor 88 and the length of the sliding sleeve 87, so that when the infrared sensor 88 is not needed, the infrared sensor 88 can be completely retracted into the protective sleeve 82, so that the protective sleeve 82 can protect the infrared sensor 88 and make the infrared sensor 88 less prone to damage.

[0031] In an embodiment of this utility model, the locking block 6 engages with the gear 5, and the end of the locking block 6 away from the spring 7 is fixedly connected to the inner wall of the pull plate 4. When the fixed cylinder 1 is rotated, the fixed cylinder 1 drives the gear 5 to rotate inside the pull plate 4, so that the locking block 6 can fix the rotated gear 5, thereby fixing the position of the fixed cylinder 1, and thus enabling the lighting fixture to provide stable illumination.

[0032] In this invention, when in use, rotating the fixed cylinder 1 to a suitable angle causes the lamp tube 3 to emit light, and the diffuser plate 2 enhances the luminous efficiency of the lighting fixture. When the infrared sensor 88 is needed, rotating the turntable 83 causes the threaded rod 86 to rotate, which in turn causes the sliding sleeve 87 to move the infrared sensor 88. At this time, the infrared sensor 88 moves smoothly within the protective sleeve 82 through the cooperation of the limiting strip and the sliding groove, allowing the infrared sensor 88 to extend out of the protective sleeve 82. The gas spring rod 81 then changes the position of the infrared sensor 88 to adapt to different environments and prevent the infrared sensor 88 from being bumped. When the infrared sensor 88 is not needed, it can be completely retracted into the protective sleeve 82. When the cover plate 91 is rotated, the locking block 95 engages with the slot 93, and the cover plate 91 remains closed, preventing the infrared sensor 88 from easily accumulating dust when not in use. To unlock, simply move the lever 94 to separate the locking block 95 from the slot 93, allowing the cover plate 91 to rotate again.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
