Description

Technical Field

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

[0002] Lighting lamps are light sources that emit light and heat through electrical energy. Currently, the lighting lamps used in delivery rooms are generally shadowless lamps.

[0003] Chinese Patent Publication No. CN216408631U discloses a lighting device for assisted delivery in an obstetrics and gynecology delivery room, including a base. The top of the base is provided with a height adjustment mechanism, which includes a vertical plate, a vertical rod, a first fixed column, an inclined plate, a spring, a horizontal plate, a long rod, a second fixed column, and a lamp. The vertical plate is fixedly installed on one side of the top of the base, and the vertical rod is slidably connected to one side of the vertical plate. The first fixed column is fixedly installed on the bottom side of the vertical rod, and the second fixed column is fixedly installed on the top side of the vertical rod. The inclined plate is rotatably connected to the top of the base, and one end of the inclined plate is sleeved with the first fixed column. Two sets of horizontal plates are fixedly installed on the top of the vertical plate.

[0004] This invention allows for height adjustment of the lamp by stepping on an inclined plate. The inclined plate rotates, pushing the vertical rod upwards, which in turn slides the second fixed column in the waist-shaped groove of the long rod. This causes the long rod to rotate, lowering the lamp. Thus, the lamp height can be adjusted by stepping on the inclined plate, eliminating the need for manual operation and making it convenient to use. However, when using this device, after adjusting the lamp height by stepping on the inclined plate, medical staff need to maintain the position of stepping on the inclined plate to keep the lamp at that height. Once the medical staff removes their foot from the inclined plate, the lamp returns to its initial height. Since medical staff cannot remain stationary while monitoring the mother, it is impossible to guarantee that the lamp height will remain unchanged after adjustment, affecting the use by medical staff.

[0005] In view of this, we propose a lighting lamp. Utility Model Content

[0006] The purpose of this utility model is to provide a lighting lamp to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides a lighting lamp, including a base, a support rod fixedly connected to the top of the base via an adjustment assembly, a horizontal support rod connected to the upper end of the support rod, and a lamp panel fixedly connected to the other end of the horizontal support rod via an adjustment bracket;

[0008] The adjustment assembly includes a control box, inside which a control gear is rotatably connected. A first rack and a second rack are respectively provided at the front and rear ends of the control gear. Both the first rack and the second rack mesh with the control gear. A foot pedal is fixedly connected to the front surface of the first rack via a connecting block. The lower surface of the support rod is fixedly connected to the upper surface of the second rack. A control groove for the connecting block to move is provided on the front surface of the control box.

[0009] The upper end of the foot pedal is provided with an inverted U-shaped movable plate. A T-shaped slider is fixedly connected to the lower surface of the inverted U-shaped movable plate. A sliding groove for the movement of the T-shaped slider is opened on the upper surface of the foot pedal. A return spring is fixedly connected to the inner wall of the sliding groove. The other end of the return spring is fixedly connected to the outer wall of the T-shaped slider. A control block is fixedly connected to the rear surface of the inverted U-shaped movable plate. Positioning blocks are symmetrically fixedly connected to the outer wall of the control block. Multiple positioning grooves corresponding to the positioning blocks are symmetrically opened on the inner wall of the front end of the control box.

[0010] As a further improvement to this technical solution, sliding blocks are symmetrically fixedly connected to both sides of the first rack and the second rack, and two guide rails corresponding to the sliding blocks are symmetrically fixedly connected to the inner walls of both sides of the control box. Guide grooves adapted to the guide rails are opened on the outer walls of the multiple sliding blocks.

[0011] As a further improvement to this technical solution, the lamp panel has a heat dissipation groove inside, and a mounting groove communicating with the heat dissipation groove is opened on the rear surface of the lamp panel. A cooling fan is fixedly installed inside the mounting groove. The front surface of the lamp panel has multiple air inlets communicating with the heat dissipation groove. Two heat dissipation plates are fixedly connected inside the heat dissipation groove, and heat dissipation fins are fixedly connected between the two heat dissipation plates.

[0012] As a further improvement to this technical solution, a protective cover is fixedly connected to the rear surface of the lamp panel. The outer wall of the protective cover has multiple air venting slots. A sealing cover is movably fitted onto the outside of the protective cover.

A sealing ring for sealing multiple air inlets is fixedly connected to the front surface of the control cover. Multiple ventilation grooves corresponding to the air inlets are opened on the front surface of the sealing ring. Filter screens are fixedly connected inside the multiple ventilation grooves.

[0014] As a further improvement to this technical solution, the upper surface of the C-shaped movable plate is fixedly connected with friction ridges, and the outer wall of the control cover is fixedly connected with a control handle.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In this type of lighting, medical staff can move a control block by pushing a C-shaped movable plate with their foot, causing the positioning block to disengage from the positioning groove. Then, stepping down or lifting the C-shaped movable plate moves the foot pedal, which in turn moves the first rack downwards. Under the control of the control gear, the second rack moves the support rod upwards. This allows for manual height adjustment of the lamp panel, saving unnecessary operations and preventing cross-infection from manual adjustments. After releasing the C-shaped movable plate from the pressure of the spring, the T-shaped slider moves the C-shaped movable plate back to its original position, allowing the positioning block to enter the corresponding positioning groove under the control of the control block. This restricts the height of the C-shaped movable plate and the foot pedal, ensuring the lamp panel remains stable after height adjustment and facilitating operation by medical staff.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 - Figure 5 As shown, this embodiment provides a lighting lamp, including a base 1. A support rod 2 is fixedly connected to the top of the base 1 through an adjustment component. A horizontal support rod 3 is connected to the upper end of the support rod 2. A lamp panel 7 is fixedly connected to the other end of the horizontal support rod 3 through an adjustment bracket 4.

[0026] The adjustment assembly includes a control box 5, and a control gear 6 is rotatably connected inside the control box 5. A first rack 8 and a second rack 9 are respectively provided at the front and rear ends of the control gear 6. Both the first rack 8 and the second rack 9 mesh with the control gear 6. A foot pedal 11 is fixedly connected to the front surface of the first rack 8 through a connecting block 10. The lower surface of the support rod 2 is fixedly connected to the upper surface of the second rack 9. A control groove 12 for the connecting block 10 to move is opened on the front surface of the control box 5.

[0027] The upper end of the foot pedal 11 is provided with a C-shaped movable plate 13. A T-shaped slider 14 is fixedly connected to the lower surface of the C-shaped movable plate 13. A sliding groove 15 for the T-shaped slider 14 to move is opened on the upper surface of the foot pedal 11. A return spring 16 is fixedly connected to the inner wall of the sliding groove 15. The other end of the return spring 16 is fixedly connected to the outer wall of the T-shaped slider 14. A control block 17 is fixedly connected to the rear surface of the C-shaped movable plate 13. A positioning block 18 is symmetrically fixedly connected to the outer wall of the control block 17. A plurality of positioning grooves 19 corresponding to the positioning blocks 18 are symmetrically opened on the inner wall of the front end of the control box 5.

[0028] The working principle is as follows: In use, medical staff first move the base 1 to the vicinity of the delivery bed. Then, they adjust the angle of the lamp panel 7 by adjusting the bracket 4 to ensure illumination of the patient. When the height of the lamp panel 7 needs adjustment, the medical staff can step on the U-shaped movable plate 13, which will then push the U-shaped movable plate 13 to move the control block 17. This causes the T-shaped slider 14 to compress the return spring 16, disengaging the positioning block 18 from the positioning groove 19. At this point, the medical staff can step down on the U-shaped movable plate 13, causing the foot pedal 11 to move the first rack 8 downwards under the action of the connecting block 10. With the cooperation of the control gear 6, the second rack 9 moves the support rod 2 upwards, completing the upward height adjustment of the lamp panel 7. When the desired position is reached, the medical staff remove their foot from the U-shaped movable plate 13. 3. When removed from the top, the elastic force of the return spring 16 allows the C-shaped movable plate 13 to drive the control block 17 to reset, and the positioning block 18 to enter the positioning groove 19 of the corresponding height, thus limiting the height position of the lamp panel 7. When the lamp panel 7 needs to be moved downward, medical staff only need to push the C-shaped movable plate 13 with their feet to move it, which can release the restriction of the positioning block 18 on the position of the foot pedal 11. By pushing the C-shaped movable plate 13 upward, the support rod 2 and the lamp panel 7 can be lifted upward with the cooperation of the first rack 8, the second rack 9 and the control gear 6. When the height is adjusted, the positioning block 18 can also be locked into the positioning groove 19 of the corresponding position under the elastic force of the return spring 16, so that the lamp panel 7 does not need to be controlled after the height is adjusted, which is convenient for medical staff to use.

[0029] To ensure the stability of the first rack 8 and the second rack 9 during their movement, sliding blocks 20 are symmetrically fixedly connected to both sides of the first rack 8 and the second rack 9. Two guide rails 21 corresponding to the sliding blocks 20 are symmetrically fixedly connected to the inner walls of both sides of the control box 5. The outer walls of the multiple sliding blocks 20 are provided with guide grooves that are adapted to the guide rails 21. When the first rack 8 and the second rack 9 move, the movement of the first rack 8 and the second rack 9 can be guided by the cooperation of the sliding blocks 20 and the guide rails 21, thereby ensuring the stability of the first rack 8 and the second rack 9 during their movement.

[0030] To prevent patient discomfort and tissue dryness in the surgical area due to excessive heat during lamp panel 7 use, a heat dissipation groove 22 is provided inside the lamp panel 7. A mounting groove communicating with the heat dissipation groove 22 is provided on the rear surface of the lamp panel 7, and a cooling fan 24 is fixedly installed inside the mounting groove. Multiple air inlets 23 communicating with the heat dissipation groove 22 are provided on the front surface of the lamp panel 7. Two heat dissipation plates 25 are fixedly connected inside the heat dissipation groove 22, and heat dissipation fins 26 are fixedly connected between the two heat dissipation plates 25. When the lamp panel 7 is in use, the cooling fan 24 can be turned on, allowing air from the front of the lamp panel 7 to enter the heat dissipation groove 22 through the multiple air inlets 23 and then be discharged through the mounting groove. The heat dissipation plates 25 and heat dissipation fins 26 work together to guide the heat generated by the lamp panel 7 during operation. As the airflow passes through the heat dissipation fins 26, the heat on the heat dissipation fins 26 is carried away, ensuring that the lamp panel 7 does not cause patient discomfort or tissue dryness in the surgical area due to excessive heat during use.

[0031] To prevent dust from entering the interior of the lamp panel 7 when heat dissipation is not in progress, a protective cover 27 is fixedly connected to the rear surface of the lamp panel 7. The outer wall of the protective cover 27 has multiple air vents 28. A sealing cover 29 is movably fitted over the protective cover 27. The outer wall of the sealing cover 29 has multiple reserved slots 30 corresponding to the air vents 28. When heat dissipation is in progress, the multiple reserved slots 30 on the sealing cover 29 overlap with the multiple air vents 28, and the exhaust hot air can be discharged through the multiple air vents 28. Dust will not enter the lamp panel 7 through the air vents 28. When heat dissipation is not in progress, the sealing cover 29 can be controlled to seal the multiple air vents 28 to prevent dust from entering the interior of the lamp panel 7.

[0032] During operation, the rotation of the enclosure 29 needs to be easily controlled, so a control cover 31 is movably fitted on the outside of the lamp panel 7. The rear surface of the control cover 31 is fixedly connected to the front surface of the enclosure 29. A sealing ring 32 for sealing multiple air inlets 23 is fixedly connected to the front surface of the control cover 31. Multiple ventilation slots 33 corresponding to the air inlets 23 are opened on the front surface of the sealing ring 32. A filter screen 34 is fixedly connected inside each of the multiple ventilation slots 33. In use, rotating the control cover 31 can drive the enclosure 29 and the sealing ring 32 to rotate, thereby facilitating the sealing and exposure of the air inlets 23 and the air outlet slots 28, which is convenient for heat dissipation. The filter screen 34 can prevent dust from entering the interior of the lamp panel 7.

[0033] In addition, medical staff need to ensure the stability of the C-shaped movable plate 13 and the lamp panel 7. Therefore, friction ridges 35 are fixedly connected to the upper surface of the C-shaped movable plate 13, and control handles 36 are fixedly connected to the outer wall of the control cover 31. During use, the friction ridges 35 can ensure the stability of the C-shaped movable plate 13 when the medical staff steps on it, while the control handles 36 make it convenient for the medical staff to rotate the control cover 31 or adjust the angle of the entire lamp panel 7.
