Description

Technical Field

[0001] This utility model relates to the field of shadowless lamp technology, and in particular to a medical shadowless lamp with a replaceable reflector cup. Background Technology

[0002] In existing medical shadowless lamp designs, the reflector cup is usually directly fixed to the lamp holder with screws or uses an integrated structure.

[0003] This structure has significant drawbacks: First, when the reflector cup ages, its plating peels off, or it becomes contaminated due to long-term use, the replacement process is extremely cumbersome, requiring professional personnel to use tools to remove multiple screws, resulting in lengthy maintenance time and disrupting the normal operation of the operating room. Second, repeated disassembly and reassembly can easily lead to stripped threads or damage to sealing elements, affecting the lamp's sealing performance and posing a risk of dust or liquid entering the lamp body. Furthermore, traditional fixing methods struggle to provide effective axial cushioning while ensuring tightness; when the lamp is subjected to accidental impact, the impact force can be directly transmitted to the delicate internal light-emitting elements, causing damage. Therefore, there is an urgent need for a reflector cup fixing solution that enables quick, tool-free replacement while possessing excellent sealing and reliable connection. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a medical shadowless lamp with a replaceable reflector cup.

[0023] Example 1, as Figures 1-4 As shown, this utility model proposes a medical shadowless lamp with a replaceable reflector cup, including a lamp housing 1, a reflector cup 10, a beetle-shaped reflector, a push rod 15, and an annular silicone film 16. A column head 2 coaxially mounted on the lamp housing 1 is provided. Several lamp holders 3 are arranged around the column head 2 on the lamp housing 1. The lamp holders 3 are connected to the lamp housing 1 by several screws 4. A groove 31 is provided on the lamp holder 3, and a light-emitting element is provided on the bottom surface of the groove 31. The light-emitting element includes a lamp post 5 and an LED 6. The lamp post 5 is connected to the lamp holder 3, and the LED 6 is connected to the top of the lamp post 5. A short groove A32 coaxially connected to the groove 31 and a short groove B34 coaxially connected to the short groove A32 are provided on the lamp holder 3. The short groove B34 is located near the upper opening of the lamp holder 3, and its inner diameter is larger than the outer diameter of the short groove A32. A sealing ring A7 is coaxially mounted on the short groove A32, and a sealing ring B9 is coaxially mounted on the short groove B34.

[0024] The reflector cup 10 is coaxially inserted into the groove 31 and fits against its inner wall. The reflector cup 10 is provided with an insertion hole 1001 for the light-emitting element to be inserted into its cavity. The sealing ring A7 abuts against the outer end face of the reflector cup 10. A limiting ring 12 is coaxially provided on the outer surface of the reflector cup 10, and the lower end face of the limiting ring 12 abuts against the upper end face of the sealing ring B9. The lamp holder 3 is provided with a guide groove 35 parallel to its axis on the outer arc surface of the short groove A32. A positioning block adapted to the guide groove 35 is provided on the outer wall of the reflector cup 10 to prevent the reflector cup 10 from rotating relative to the lamp holder 3 through the cooperation of the guide groove 35 and the positioning block.

[0025] The beetle bouncer includes a bouncer female buckle 8 and a bouncer male plug 14. A storage groove 33, communicating with the bottom surface of the low groove A32, is provided on the lamp holder 3. The bouncer female buckle is connected to the bottom surface of the storage groove 33. The bouncer male plug 14 is slidably connected to the reflector cup 10, and a through hole 71 is provided on the sealing ring A7 for the bouncer male plug 14 to pass through. The bouncer male plug 14 is adapted to the bouncer female buckle 8. A push rod 15 is mounted on the reflector cup 10 and slides along its height direction. The push rod 15 is connected to the bouncer male plug 14. A groove is provided on the reflector cup 10, and a slider 13 is installed in the groove. The lower end of the slider 13 is connected to the male connector 14 of the reflector, and the upper end of the slider 13 is connected to the push rod 15. The stroke of the slider 13 in the groove is set according to the matching distance between the female connector 8 and the male connector 14 of the reflector, to prevent the reflector cup 10 from sliding along the axial direction of the lamp holder 3 when the male connector 14 and the female connector 8 of the reflector are locked. This structure is used in conjunction with a sealing ring B9, which allows the reflector cup 10 to slide appropriately along the axial direction of the lamp holder 3 within a certain range and maintain good sealing. An annular silicone film 16 is connected to the annular end face of the reflector cup 10, and a bowl-shaped protrusion 161 corresponding to the push rod 15 is provided on the annular silicone film 16.

[0026] In this embodiment, the reflector cup 10, the beetle-shaped bouncer, the push rod 15, and the annular silicone film 16 work together to achieve rapid installation, sealing, and convenient replacement of the reflector cup 10. A coaxial column head 2 is provided on the lamp housing 1, and several lamp holders 3 are arranged around its perimeter. The lamp holders 3 are fixedly connected to the lamp housing 1 by screws 4. Light-emitting elements, including a lamp column 5 and an LED 6, are installed on the bottom surface of the groove 31 of the lamp holder 3 to provide a lighting source. The reflector cup 10 is coaxially inserted into the groove 31 and accommodates the light-emitting elements through the insertion hole 1001 to reflect and focus light, forming a uniform, shadowless effect.

[0027] For sealing, the lamp holder 3 has a short groove A32 and a short groove B34. A sealing ring A7 is coaxially mounted on the short groove A32, and a sealing ring B9 is coaxially mounted on the short groove B34. When the reflector cup 10 is inserted, its outer end face abuts against the sealing ring A7, while the lower end face of the limiting ring 12 on the outer surface of the reflector cup 10 abuts against the upper end face of the sealing ring B9, forming a double seal to prevent dust or liquid from entering. At the same time, the guide groove 35 of the lamp holder 3 cooperates with the positioning block on the outer wall of the reflector cup 10 to prevent the reflector cup 10 from rotating relative to the lamp holder 3, ensuring accurate positioning.

[0028] The beetle-shaped bouncer is used to lock the reflector cup 10 and includes a bouncer female buckle 8 and a bouncer male plug 14. The bouncer female buckle 8 is fixed in the receiving groove 33 of the lamp holder 3, and the bouncer male plug 14 is slidably connected to the reflector cup 10 and passes through the through hole 71 on the sealing ring A7. The push rod 15 slides along the height direction of the reflector cup 10 and is connected to the bouncer male plug 14 through the slider 13. The stroke of the slider 13 in the groove is set according to the matching distance between the bouncer female buckle 8 and the bouncer male plug 14 to ensure that the reflector cup 10 will not slide axially when locked, while the sealing ring B9 allows the reflector cup 10 to move slightly axially to maintain a seal.

[0029] The annular silicone film 16 is connected to the annular end face of the reflector cup 10, and a bowl-shaped protrusion 161 is provided on it corresponding to the push rod 15. When the reflector cup 10 needs to be replaced, the user presses the bowl-shaped protrusion 161, pushes the push rod 15 downward, causing the slider 13 and the male connector 14 of the reflector to disengage from the female connector 8 of the reflector, and the reflector cup 10 can be removed. During installation, the new reflector cup 10 is inserted into the guide groove 35, and the male connector 14 of the reflector automatically locks with the female connector 8 of the reflector, achieving quick fixation. The entire process is sealed reliably, easy to operate, and suitable for efficient maintenance of medical shadowless lamps.

[0030] Example 2, as Figure 2 and Figure 4 As shown, the present invention proposes a medical shadowless lamp with a replaceable reflector cup. Compared with the first embodiment, the lamp post 5 is provided with a circular ring 51 coaxially arranged on the lamp post 5, and the reflector cup 10 is provided with a circular groove with an outer diameter larger than the insertion hole 1001 and coaxially connected to the insertion hole 1001. A sealing ring C11 is provided on the upper wall of the circular groove, and the sealing ring C11 abuts against the upper end face of the circular ring 51.

[0031] In this embodiment, the sealing ring C11 is used to ensure that there is no gap between the lamp post 5 and the inner wall of the insertion hole 1001 on the reflector cup 10 during the connection process with the lamp holder 3, thereby preventing dust and other sources of pollution from entering.
