Description

Technical Field

[0001] The utility model relates to the technical field of lighting moisture-proof, and more specifically, to a grille lamp body structure with a high-precision opening. Background Art

[0002] Grille lights are a type of lighting fixture, suitable for installation in offices with suspended ceilings. The reflective back panel of grille lights is made of mirrored aluminum and is designed with a deep arc shape to achieve a better reflective effect. Grille lights are energy-saving, environmentally friendly and have a long service life. Grille lights are an indoor fixture and therefore do not have moisture-proof functions. A humid environment will not only reduce the service life of the grille lights, but will also corrode the internal parts of the fixture and cause a short circuit.

[0003] The existing technology places a desiccant in the grille lamp to protect the grille lamp, but people cannot promptly detect whether the desiccant in the grille lamp still has a water absorption effect. When the desiccant has lost its water absorption effect and is not replaced in time, the moisture in the air that cannot be absorbed may reduce the life of the grille lamp or corrode parts to cause a short circuit. Therefore, a grille lamp with a high-precision opening is designed to solve the problem that the grille lamp cannot be continuously moisture-proof. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a grille lamp body structure with a high-precision opening, and to reduce the time during which the grille lamp cannot be dehumidified by providing a spare dehumidifier, thereby extending the service life of the grille lamp.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: the high-precision open grille lamp body structure includes a reflective back plate and a plurality of frames, the plurality of frames are detachably connected to the reflective back plate, the frames are detachably connected with a desiccant, a placement groove is provided on one side of the frame close to the reflective back plate, a placement sheet and a storage sheet are rotatably connected on the inner side wall of the placement groove, the horizontal height of the storage sheet is higher than the horizontal height of the placement sheet, the desiccant is slidably connected to the placement sheet, the storage sheet is slidably connected with a spare dehumidifier, and when the weight of the desiccant increases, the spare dehumidifier slides from the storage sheet through the temporary storage groove to the placement sheet.

[0006] By adopting the above technical scheme, the placement groove opened in the frame contains desiccant, which can absorb moisture in the air around the grille lamp to prevent moisture from damaging parts and causing short circuit. A placement sheet for placing the desiccant and a storage sheet for placing the spare dehumidifier are rotatably connected on the inner wall of the placement groove. When the desiccant absorbs moisture in the air, its weight increases, which allows the storage sheet and the placement sheet to rotate, so that the spare dehumidifier on the storage sheet slides to the placement sheet through the temporary storage groove to replace the desiccant that can no longer absorb moisture. Automatic replacement can prevent the moisture in the air from corroding parts and causing short circuit or affecting the service life of the grille lamp due to the inability to replace it in time after the desiccant loses its water absorption effect.

[0007] The utility model is further configured as follows: the temporary storage groove is arranged on a side of the frame body close to the reflective back plate, the temporary storage groove is arranged at an end away from the rotation axis of the placement piece, the temporary storage groove is connected with the placement groove, the lowermost end of the temporary storage groove is at the same horizontal height as the placement piece, the height of the temporary storage groove is the same as the distance between the placement piece and the storage piece, and the distance between the bottom surface of the temporary storage groove away from one end of the placement groove and the bottom surface of the frame body is greater than the distance between the other end of the temporary storage groove and the bottom surface of the frame body.

[0008] By adopting the above technical solution, when the storage sheet rotates, the distance between one end of the storage sheet close to the temporary storage slot and the bottom of the frame is smaller than the distance between the upper top of the temporary storage slot opening and the bottom of the frame, and the inclination angle of the storage sheet allows the standby dehumidifier to slide from the storage sheet into the temporary storage slot. When the placement sheet and the storage sheet return to their initial positions, the standby dehumidifier in the temporary storage slot will slide onto the placement sheet due to the inclined setting of the bottom surface of the temporary storage slot.

[0009] The utility model is further configured as follows: one end of the placement sheet close to the temporary storage slot is rotatably connected to a linkage rod, and one end of the linkage rod away from the placement sheet is rotatably connected to the storage sheet.

[0010] By adopting the above technical solution, when the placement plate rotates, the placement plate generates a downward pulling force on the storage plate through the connecting rod, so that the storage plate rotates. Since the height of the connecting rod and the distance between the placement plate and the storage plate are the same, the connecting rod, the storage plate and the placement plate form a movable parallelogram so that the storage plate and the placement plate can always remain parallel.

[0011] The utility model is further configured as follows: an elastic member 1 is fixedly connected to one side of the placement sheet close to the temporary storage slot and away from the storage sheet, and an end of the elastic member 1 away from the placement sheet is fixedly connected to the bottom surface of the placement slot.

[0012] By adopting the above technical solution, the supporting force of the elastic member on the placement sheet is the same as the sum of the weight of the placement sheet and the desiccant. When the weight of the desiccant increases, pressure is generated on the placement sheet to cause the placement sheet to rotate downward. The downward rotation of the placement sheet generates pressure on the elastic member 1 to compress the elastic member 1. When the pressure of the desiccant on the placement sheet disappears, the pressure applied to the elastic member 1 disappears. The elastic member will return to its initial state due to its own elastic deformation performance, thereby generating an upward thrust on the placement sheet to cause the placement sheet to rotate upward.

[0013] The utility model is further configured as follows: a sliding groove is provided on one side of the frame body close to the temporary storage groove, the sliding groove is connected to the placement groove, the horizontal height of the top surface of the sliding groove is lower than the lowest end of the temporary storage groove, and when the weight of the desiccant increases, the desiccant slides on the placement sheet into the sliding groove.

[0014] By adopting the above technical solution, when the weight of the desiccant increases, downward pressure is generated on the placement sheet, causing the placement sheet to rotate. After the placement sheet rotates, the distance between one end of the placement sheet close to the sliding groove and the bottom surface of the frame is smaller than the distance between the other end of the placement sheet and the bottom surface of the frame, causing the placement sheet to tilt at an angle. The distance between one end of the placement sheet close to the sliding groove and the bottom surface of the frame is smaller than the distance between the top surface of the sliding groove and the bottom surface of the frame, and the desiccant slides on the tilted placement sheet and enters the sliding groove.

[0015] The utility model is further configured as follows: a shielding sheet is detachably connected to one end of the inner wall of the placement groove close to the reflective back plate, and the distance between the shielding sheet and the linkage rod is offset.

[0016] By adopting the above technical solution, the shielding sheet seals the desiccant and the standby dehumidifier in the placement groove, preventing the desiccant and the standby dehumidifier from falling and avoiding the standby dehumidifier from contacting with the outside air.

[0017] The utility model is further configured as follows: a plurality of ventilation holes are provided on the shielding sheet, and the ventilation holes are communicated with the placement groove.

[0018] By adopting the above technical solution, the vent hole connects the space between the placement sheet and the storage sheet in the placement groove with the external air, and the vent hole enables the desiccant to absorb external moisture.

[0019] In summary, the grille lamp with a high-precision opening is provided with a spare dehumidifier, which can automatically replace the desiccant that has fully absorbed water. When the desiccant on the placement sheet fully absorbs water and its own weight increases, it generates downward pressure on the placement sheet to cause the placement sheet to rotate. The rotation of the placement sheet will cause the storage sheet to rotate through the connecting rod. After the storage sheet rotates, it tilts to cause the spare dehumidifier on the storage sheet to slide into the temporary storage groove. When the desiccant on the placement sheet slides into the sliding groove, the placement sheet returns to its initial position due to the elastic force of the elastic part 1, and the spare dehumidifier in the temporary storage groove slides onto the placement sheet to continue to absorb moisture in the air, thereby preventing the desiccant from absorbing too much moisture and failing, and causing the circuit to short-circuit due to the inability to be discovered and replaced in time.

DETAILED DESCRIPTION

[0026] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the high-precision open grille lamp body structure includes a reflective backboard 1 and two frames 2. The frames 2 are detachably connected to the two sides of the reflective backboard 1. The frames 2 are recessed inward to form a placement groove 5. A placement sheet 6 and a storage sheet 7 are rotatably connected to the inner side wall of the placement groove 5. The horizontal height of the storage sheet 7 is higher than that of the placement sheet 6. A desiccant 3 is placed on the placement sheet 6. The desiccant 3 can absorb moisture around the grille lamp to prevent moisture from damaging parts and causing a short circuit or affecting the service life of the grille lamp. A spare dehumidifier 4 is placed on the storage sheet 7. When the desiccant 3 fully absorbs moisture and its own weight increases, the spare dehumidifier 4 on the storage sheet 7 will slide to the placement sheet 6 through the temporary storage groove 8 to replace the desiccant 3 that has fully absorbed moisture. After sliding to the placement sheet 6, the spare dehumidifier 4 continues to absorb moisture around the grille lamp.

[0028] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the temporary storage groove 8 is provided on one side of the frame 2 close to the reflective back plate 1 and is connected with the placement groove 5. The temporary storage groove 8 is away from one end of the rotation axis of the placement sheet 6. The lower end of the temporary storage groove 8 is at the same horizontal height as the placement sheet 6. The height of the temporary storage groove 8 is the same as the distance between the placement sheet 6 and the storage sheet 7. When the weight of the desiccant 3 increases due to water absorption, the pressure exerted by the desiccant 3 on the placement sheet 6 causes the placement sheet 6 to rotate, thereby driving the storage sheet 7 to rotate. Since the distance between the end of the storage sheet 7 close to the temporary storage groove 8 and the bottom of the frame 2 is less than the distance between the top of the notch of the temporary storage groove 8 and the bottom of the frame 2 after the storage sheet 7 rotates, the storage sheet 7 generates an inclined angle so that the standby dehumidifier 4 slides on the storage sheet 7 into the temporary storage groove 8. When the placement sheet 6 and the storage sheet 7 return to the initial position, since the height of the bottom surface of the temporary storage groove 8 away from one end of the placement groove 5 is greater than the height of the other end of the temporary storage groove 8, the standby dehumidifier 4 in the temporary storage groove 8 slides from the temporary storage groove 8 to the placement sheet 6.

[0029] like Figure 3-Figure 5 As shown, the placement sheet 6 and the storage sheet 7 are connected at one end close to the temporary storage slot 8 through a connecting rod 9, and the two ends of the connecting rod 9 are respectively rotatably connected to the placement sheet 6 and the storage sheet 7, and the height of the connecting rod 9 is the same as the distance between the placement sheet 6 and the storage sheet 7. The connecting rod 9, the storage sheet 7 and the placement sheet 6 form a movable parallelogram structure so that the storage sheet 7 and the placement sheet 6 can always remain parallel. When the placement sheet 6 rotates, the placement sheet 6 generates a pulling force on the connecting rod 9 to make the connecting rod 9 move downward, and the downward movement of the connecting rod 9 generates a downward pulling force on the storage sheet 7 to rotate the storage sheet 7.

[0030] like Figure 3-Figure 5As shown, an elastic member 10 is bonded to one end of the placement sheet 6 close to the temporary storage groove 8 and away from the storage sheet 7. The elastic member 10 is set as a spring, and the other end of the spring is bonded to the bottom surface of the placement groove 5. The supporting force of the elastic member 10 on the placement sheet 6 is the same as the combined weight of the placement sheet 6 and the desiccant 3. When the weight of the desiccant 3 increases, the combined weight of the placement sheet 6 and the desiccant 3 increases, thereby increasing the downward pressure on the elastic member 10 and the elastic member 10 is compressed. When the desiccant 3 slides into the sliding groove 11 after fully absorbing water, the pressure on the elastic member 10 decreases, and the elastic member 10 returns to the initial state due to its own elastic deformation performance, thereby generating an upward thrust on the placement sheet 6 to rotate the placement sheet 6 upward.

[0031] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, a sliding groove 11 is provided on one side of the frame 2 near the temporary storage groove 8, and the sliding groove 11 is connected to the placement groove 5. The horizontal height of the top surface of the sliding groove 11 is lower than the lowest end of the temporary storage groove 8. When the weight of the desiccant 3 increases, a downward pressure is generated on the placement sheet 6 to rotate the placement sheet 6. After the placement sheet 6 rotates, the height of one end near the sliding groove 11 is lower than the height of the other end, resulting in an inclined angle and the distance from one end near the sliding groove 11 to the bottom surface of the frame 2 is less than the distance from the top surface of the sliding groove 11 to the bottom surface of the frame 2. The desiccant 3 slides on the inclined placement sheet 6 into the placement groove 5, so that the pressure on the placement sheet 6 disappears.

[0032] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, four elastic members 12 are bonded to the top surface of the sliding groove 11, and the elastic members 12 are configured as springs 2. One end of the elastic members 12 away from the temporary storage groove 8 is bonded to the box body 15. In the initial state, the supporting force of the elastic members 12 on the box body 15 is equal to the gravity of the box body 15 itself. After the desiccant 3 fully absorbs moisture, it slides into the sliding groove 11 and enters the box body 15. The gravity of the desiccant 3 after fully absorbing moisture and the box body 15 generates a pulling force on the elastic member 12, so that the elastic member 12 is stretched. The stretching of the elastic member 12 causes the box body 15 to slide downward on the sliding groove 11, thereby protruding from the frame 2 so that people can find that when the desiccant 3 in the box body 15 is taken out, the pulling force applied to the elastic member 12 is reduced, and the elastic member 12 can return to the initial state due to its own elastic deformation performance, thereby generating an upward pulling force on the box body 15, so that the box body 15 slides upward and returns to the initial state.

[0033] like Figure 1-Figure 5As shown, a shielding piece 13 is detachably connected to one end of the inner wall of the placement groove 5 close to the reflective back plate 1. The shielding piece 13 has the same cross-sectional area as the placement groove 5. The shielding piece 13 prevents the standby dehumidifier 4 from contacting with the external air and also prevents the desiccant 3 and the standby dehumidifier 4 from falling. The distance between the shielding piece 13 and the connecting rod 9 is greater than or equal to zero, so that the connecting rod 9 will not generate friction with the shielding piece 13 when moving and the shielding piece 13 will not be lifted up by the connecting rod 9. The shielding piece 13 is provided with air vents 14 distributed in a linear array. The air vents 14 connect the air in the placement groove 5 with the external air. The air vents 14 are distributed between the placement piece 6 and the storage piece 7, so that the desiccant 3 on the placement piece 6 can absorb moisture in the air around the external grille lamp.

[0034] Working principle: When the high-precision open grille lamp body structure is in use, the desiccant 3 on the placement sheet 6 in the frame 2 can absorb moisture in the air around the grille lamp through the vents 14 on the shielding sheet 13 to prevent moisture from corroding the parts of the grille lamp and causing a short circuit. When the desiccant 3 absorbs a large amount of moisture and cannot continue to absorb, its own weight exerts a downward pressure on the placement sheet 6, causing the placement sheet 6 to rotate downward. The rotation of the placement sheet 6 exerts a downward pulling force on the storage sheet 7 through the linkage rod 9, causing the storage sheet 7 and the placement sheet 6 to rotate downward at the same time. During the downward rotation process, the desiccant 3 in the placement sheet 6 will slide and enter the box 15 in the sliding groove 11. At the same time, the spare dehumidifier 4 on the storage sheet 7 is due to the storage sheet 7 generates an inclined angle and slides into the temporary storage groove 8. When the force on the placement sheet 6 disappears, the elastic member 10 will restore the initial state due to its own elastic deformation performance, thereby generating an upward thrust on the placement sheet 6, so that the placement sheet 6 and the storage sheet 7 rotate upward and return to their original positions. The spare dehumidifier 4 that slides into the temporary storage groove 8 will slide onto the placement sheet 6 and continue to absorb moisture in the air around the grille lamp through the vent 14. The desiccant 3 that slides into the box body 15 generates a downward pressure on the box body 15, causing the elastic member 2 12 connected to the box body 15 to deform. The elastic member 2 12 is stretched to cause the box body 15 to slide downward and protrude from the surface of the frame body 2, making it easy for people to find it, remove and open the shielding sheet 13, and put new spare dehumidifier 4 on the storage sheet 7.

[0035] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
