Description

Technical Field

[0001] This utility model relates to the field of dental chair technology, and in particular to a dental chair for comprehensive oral treatment. Background Technology

[0002] The dental chair, also known as a dental treatment chair or simply a dental chair, is a core piece of equipment in modern dental care. Its importance is self-evident. It integrates multiple functions, providing dentists with a comprehensive and efficient treatment platform. Its working principle is ingenious and efficient: by operating the control switch, the motor is started and runs smoothly, which in turn drives the transmission mechanism to work precisely. Under this series of coordinated actions, the various components of the dental chair move flexibly. The dentist only needs to easily operate the control switch buttons according to the treatment needs, and the dental chair can quickly and accurately complete various positional adjustments and repositioning actions such as rising, falling, and tilting, providing great convenience and support for the treatment process.

[0003] A headrest is installed at the top of the dental chair. This design, with its sponge padding, provides soft and comfortable support for the patient's head, greatly improving the patient's comfort during treatment. However, given that each dental chair needs to receive many patients every day, the headrest inevitably comes into frequent contact with the heads of different patients. During this process, the oil and sweat from the patients' heads can easily remain on the surface of the headrest, which not only affects the cleanliness of the headrest but may also bring a bad experience to subsequent patients. Although disassembling and cleaning the headrest after each use can solve this problem to some extent, the frequent disassembly and cleaning work undoubtedly increases the burden on medical staff and seems quite cumbersome. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution: a dental chair for comprehensive oral treatment, comprising a dental chair and a headrest. The headrest is installed at one end of the dental chair, and a mounting bracket is installed at the rear end of the headrest through a limiting groove and a threaded hole. Both ends of the mounting bracket are fixedly connected to roller brackets. The two roller brackets are rotatably connected to an active roller and a driven roller, respectively. A thin film tube is sleeved on the surface of the driven roller, and one end of the thin film portion of the thin film tube is attached to the shaft surface of the active roller.

[0005] As an improvement to the above technical solution, the mounting bracket includes a snap-fit ​​plate and a hand-tightening screw. The snap-fit ​​plate is located inside the limiting groove at the rear end of the headrest, and the snap-fit ​​plate is threadedly connected to the headrest via the hand-tightening screw.

[0006] As an improvement to the above technical solution, the roller frame includes a fixed rod, a movable block, a rotating disk, a force transmission keyway, a sliding block, a second hand screw, and a third hand screw. Fixed rods are fixedly connected to both ends of the locking plate. A sliding block is engaged with one end of the fixed rod through a slot. The sliding block is threadedly connected to the fixed rod via the second hand screw. A movable block is fixedly connected to the upper end of the sliding block. A rotating disk is rotatably connected to the surface of the movable block. A force transmission keyway is provided at the center of the rotating disk. A third hand screw is threadedly connected to the surface of the movable block. The two rotating disks are slidably engaged with the shaft portions of the driving roller and the driven roller respectively through the force transmission keyways on their surfaces.

[0007] As an improvement to the above technical solution, the active roller includes an active shaft, a limiting disk, and a knob. The active shaft is rotatably connected to the surface of the roller frame. A knob is fixedly connected to one end of the active shaft. The other end of the active shaft is slidably engaged with a force transmission keyway via a transmission key. A limiting disk is fixedly connected to the surface of the active shaft.

[0008] As an improvement to the above technical solution, the driven roller includes a driven shaft, a rubber sleeve, and a second limiting disk. The driven shaft is rotatably connected to the surface of the roller frame, and the rubber sleeve is fixedly connected to the surface of the driven shaft. One end of the driven shaft is slidably engaged with the force transmission keyway through a transmission key. The first limiting disk is fixedly connected to the surface of the driven shaft, and the diaphragm sleeve is disposed on the surface of the rubber sleeve.

[0009] The beneficial effects of this utility model are:

[0010] Because the film covering the surface of the headrest can be rolled up and replaced using an active roller, the used film is rolled up and the unused film replaces the used film to cover the surface of the headrest. Therefore, not only can the cleanliness of the headrest be guaranteed, but it also brings a good experience to patients who use it later. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0021] Please see Figure 1-8 This utility model provides a technical solution: a dental chair for comprehensive oral treatment, including a dental chair 1 and a headrest 2. The headrest 2 is installed at one end of the dental chair 1. The rear end of the headrest 2 is installed with a mounting frame 3 through a limiting groove and a threaded hole. Both ends of the mounting frame 3 are fixedly connected to roller frames 4. The two roller frames 4 are respectively rotatably connected to an active roller 5 and a driven roller 6. A thin film tube 7 is sleeved on the surface of the driven roller 6. One end of the thin film portion of the thin film tube 7 is pasted to the shaft surface of the active roller 5.

[0022] In this implementation scheme, the user first disassembles the roller frame 4, installs the film tube 7 on the surface of the driven roller 6, then reassembles the roller frame 4, and then attaches one end of the film tube 7 to the surface of the active roller 5. At this time, the film tube 7 covers the surface of the headrest 2. When the patient's head rests on the surface of the headrest 2, the film tube 7 supports the user's head. When the next patient uses it, the user rotates the active roller 5 to roll up the film tube 7. At the same time, the film tube 7 and the driven roller 6 rotate, so that the clean film part of the film tube 7 continues to cover the surface of the headrest 2. Since the film covering the surface of the headrest 2 can be rolled up and replaced by the active roller 5, the used film is rolled up and the unused film replaces the used film to cover the surface of the headrest 2. Therefore, not only can the cleanliness of the headrest 2 be guaranteed, but it also brings a good experience to the patients using it later.

[0023] like Figure 3 As shown, the mounting bracket 3 includes a snap-fit ​​plate 31 and a hand screw 32. The snap-fit ​​plate 31 is located inside the limiting groove at the rear end of the headrest 2. The snap-fit ​​plate 31 is threadedly connected to the headrest 2 by the hand screw 32.

[0024] In this embodiment, the user slides the snap-fit ​​plate 31 into the limiting groove opened at the rear end of the headrest 2, and then uses the hand screw 32 to install the snap-fit ​​plate 31 at the rear end of the headrest 2, thereby realizing the quick installation of the mounting bracket 3.

[0025] like Figures 6 to 8 As shown, the roller frame 4 includes a fixed rod 41, a movable block 42, a rotating disk 43, a force transmission keyway 44, a sliding block 45, a second hand screw 46, and a third hand screw 47. Both ends of the locking plate 31 are fixedly connected to the fixed rod 41. One end of the fixed rod 41 is engaged with the sliding block 45 through a slot. The sliding block 45 is threadedly connected to the fixed rod 41 through the second hand screw 46. The upper end of the sliding block 45 is fixedly connected to the movable block 42. The rotating disk 43 is rotatably connected to the surface of the movable block 42. A force transmission keyway 44 is provided at the center of the rotating disk 43. The surface of the movable block 42 is threadedly connected with the third hand screw 47. The two rotating disks 43 are slidably engaged with the shaft parts of the driving roller 5 and the driven roller 6 respectively through the force transmission keyway 44 on their surfaces.

[0026] In this embodiment, the user unscrews the second hand screw 46 to disassemble the moving block 42 and the rotating disk 43. Then, the user installs the membrane cylinder 7 on the surface of the driven roller 6. After installing the membrane cylinder 7, the user slides the sliding block 45 into the slot opened at one end of the fixing rod 41. Then, the user screws on the second hand screw 46 to fix the position of the moving block 42 and the rotating disk 43. At the same time, the transmission key at one end of the shaft of the driven roller 6 slides into the force transmission keyway 44. Finally, the user removes the membrane from the membrane cylinder 7. One end is attached to the surface of the shaft of the drive roller 5. When the film needs to be wound up and replaced, the user rotates the drive roller 5, which drives the driven roller 6 and the film tube 7 to rotate. At the same time, the rotating disk 43 rotates on the surface of the moving block 42, thereby winding up the film in the film tube 7 and replacing the used film. After the winding work is completed, the user tightens the two hand screws 47 to limit the two rotating disks 43, thereby limiting the rotation of the driven roller 6 and the drive roller 5 to ensure the stability after the film is replaced.

[0027] like Figure 4 As shown, the active roller 5 includes an active shaft 51, a limiting disk 52, and a knob 53. The active shaft 51 is rotatably connected to the surface of the roller frame 4. One end of the active shaft 51 is fixedly connected to the knob 53. The other end of the active shaft 51 is slidably engaged with the force transmission keyway 44 through a transmission key. The limiting disk 52 is fixedly connected to the surface of the active shaft 51.

[0028] In this embodiment, the user rotates the knob 53, which causes the drive shaft 51, the limiting disk 52, and the rotating disk 43 to rotate simultaneously. This, in turn, causes the driven roller 6 and the film cylinder 7 to rotate through the film, thereby allowing the film used on the surface of the headrest 2 to be replaced.

[0029] like Figure 6 and Figure 8 As shown, the driven roller 6 includes a driven shaft 61, a rubber sleeve 62, and a limiting disk 63. The driven shaft 61 is rotatably connected to the surface of the roller frame 4, and the rubber sleeve 62 is fixedly connected to the surface of the driven shaft 61. One end of the driven shaft 61 is slidably engaged with the force transmission keyway 44 through a transmission key. The limiting disk 52 is fixedly connected to the surface of the driven shaft 61, and the diaphragm cylinder 7 is sleeved on the surface of the rubber sleeve 62.

[0030] In this embodiment, after the user disassembles the moving block 42 and the rotating disk 43, the user installs the film tube 7 on the surface of the rubber sleeve 62. The driven shaft 61 stabilizes the film tube 7 through the rubber sleeve 62. When the user rotates the active roller 5, the active shaft 51 drives the driven shaft 61, the limiting disk 63, the film tube 7, and the rotating disk 43 to rotate through the film, thereby allowing the film used on the surface of the headrest 2 to be replaced.

[0031] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
