[0060] According to a first aspect of the present invention, a dental chair assembly includes a track component 10, a slide component 20, an accessory component 40, a power supply component 70, and a guide component 50.

[0061] The specific structure of the above-described components of the dental chair accessory unit according to this embodiment will be described below.

[0062] In this embodiment, as Figures 1 to 10 As shown, the track component 10 is mounted on a fixed object located around the dental chair and is not connected to the dental chair, which includes a treatment chair and a side cabinet. The fixed object can be a wall, ceiling, roof, bracket, or cabinet, etc., as long as it is an object that can fix the track component 10 within the placement space of the dental chair (e.g., the examination room). In addition, the wall can be understood as a wall set at an angle to the ground, and the ceiling is set opposite to the ground. The track component 10 has a first slide rail 101 and a second slide rail 102 formed on it. The first slide rail 101 and the second slide rail 102 have the same extension shape as the track component 10. The track component 10 can be straight, curved, or bent.

[0063] like Figure 1 and Figure 2As shown, the slide 20 is mounted on the track 10 and slides in cooperation with the first slide rail 101. The matching component 40 is mounted on the slide 20, so that the matching component 40 and the slide 20 can move together relative to the track 10. In this way, the matching component 40 is assembled around the dental chair but not connected to the dental chair, so that people can get on and off from both sides of the treatment chair, which is convenient for patients to use. The matching component 40 can move together with the slide 20, so that the matching component 40 can be moved to the vicinity of the dental chair when in use and removed when not in use, saving the space occupied by the dental chair in the treatment area of ​​the clinic. This is beneficial to the layout of the dental chair matching units in the clinic, and more dental chairs can be set up in a limited space.

[0064] In this embodiment, the accessory component 40 may be an oral lamp or a treatment device.

[0065] The power supply component 70 is connected to the matching component 40 via a cable. The power supply component 70 can be a power supply component that provides electrical energy, or it can serve as a transfer component, such as an adapter interface connecting to a gas supply component or a negative pressure component, or an adapter interface connecting to a liquid supply component. Figure 6 and Figure 9 As shown, the slide block 20 is provided with a lead wire part 211 for the cable to pass through. The lead wire part 211 can be a through hole structure, or a groove or a claw structure, as long as it can guide the cable through.

[0066] In this embodiment, in the extending direction of the track member 10, the guide assembly 50 is disposed on the side of the slide member 20 away from the power supply assembly 70. For example... Figures 2 to 6 As shown, the guide assembly 50 is installed inside the track component 10 and slides in cooperation with the second slide rail 102; the cable led out from the matching component 40 passes through the lead wire part 211 and the guide assembly 50 in sequence, and then connects to the power supply component 70, so that the cable inside the track component 10 is divided into two parts by the guide assembly 50, that is, the guide assembly 50 is provided with cables on both sides in the direction perpendicular to the track component 10.

[0067] Specifically, the cables laid in the track component 10 include a first cable portion 71 disposed between the guide component 50 and the slide component 20, and a second cable portion 72 disposed between the guide component 50 and the power supply component 70. When the supporting component 40 is moved, the slide component 20 can be driven to slide along the first slide rail 101. Under the traction of the cables, the guide component 50 slides along the second slide rail 102. The displacement of the slide component 20 is different from the displacement of the guide component 50, which causes the length of one of the first cable portion 71 and the second cable portion 72 to increase and the length of the other to decrease, and the total length of the first cable portion 71 and the second cable portion 72 remains unchanged. In this way, the guide component 50 plays the role of adjusting the length of the first cable portion 71 and the second cable portion 72 in the track component 10, avoiding the cable from getting tangled when the supporting component 40 is moved, thereby ensuring smooth movement of the dental chair supporting unit and meeting the usage requirements of the dental chair.

[0068] In this embodiment, as Figures 2 to 6 As shown, the guide assembly 50 includes a fixing member 51, a movable pulley 52, a cable pulley 53, and a constant force reset member 54. The fixing member 51 is formed into a plate-like structure or a sheet-like structure. The movable pulley 52 is slidably engaged with the second slide rail 102 and installed on one side of the fixing member 51. The movable pulley 52 can be a bearing or a cylindrical block structure. In this embodiment, multiple movable pulleys 52 are arranged at intervals along the extension direction of the track member 10, such as two, to improve sliding stability and reliability. The movable pulley 52 is preferably made of plastic, so that there will be no metallic impact sound during sliding, reducing sliding noise. It should be noted that the function of the movable pulley 52 is to provide sliding guidance, and there is no requirement for a tight assembly relationship between it and the second slide rail 102, so high precision is not required.

[0069] Furthermore, such as Figures 2 to 6As shown, the cable pulley 53 slides with the cable, so that the cable is attached to part of the side wall of the cable pulley 53. The cable pulley 53 is installed on the side opposite to the movable pulley 52 on the fixed member 51. That is, the movable pulley 52 and the cable pulley 53 are installed opposite each other on both sides of the fixed member 51, so that the cable pulley 53 does not need to be installed in the second slide rail 102. Under the drive of the movable pulley 52, the cable pulley 53 can also slide relative to the second slide rail 102. The constant force reset member 54 has two ends in the extension direction connected to the track member 10 and the fixed member 51 respectively. When the movable pulley 52 moves, the constant force reset member 54 will be pulled, which will change the distance between the guide component 50 and the slide member 20, causing the length of the first cable part 71 and the second cable part 72 to change, so that the length variables of the first cable part 71 and the second cable part 72 compensate each other. Under the action of the constant force reset component 54, when the drive component 40 moves and the slide component 20 slides relative to the track component 10, the guide component 50 will drive the cable in the track to move relatively away from the power supply component 70, so that the displacement of the guide component 50 and the slide component 20 are different, thereby adjusting the length of the first cable section 71 and the second cable section 72, and straightening the first cable section 71 and the second cable section 72, so as to avoid the cable tangling and also avoid the large area occupied by the cable curling.

[0070] In this embodiment, as Figure 4 As shown, the constant force reset component 54 is a constant force tension spring with a structure similar to a measuring tape. No matter how long the constant force reset component 54 is pulled out, the force is always constant, unlike a coil spring where the tension increases with the length of the pull. This avoids excessive force reaction on the slide block 20, ensuring that the force on the slide block 20 is basically the same during the sliding process. This makes it easier for the operator to adjust the sliding. The constant force during the movement also avoids excessive force pulling the cable, which could affect the cable's lifespan, thereby improving the reliability and stability of the dental chair supporting unit.

[0071] In this embodiment, the constant force reset member 54 includes a winding portion and an extension portion, with the winding portion mounted on the fixing member 51.

[0072] Optionally, the movable pulley 52, cable pulley 53, and constant force reset component 54 are all rotatably connected to the fixed component 51. The fixed component 51 has mounting holes, and the movable pulley 52, cable pulley 53, and constant force reset component 54 can be installed on the fixed component 51 using bolts, pins, or other parts. The movable pulley 52 and cable pulley 53 can be fixedly connected and rotatably connected relative to the fixed component 51, so that when the movable pulley 52 rotates, it can drive the cable pulley 53 to rotate together.

[0073] In another alternative embodiment, the cable pulley 53 is fixedly mounted on the fixing member 51. In this case, sliding friction is formed between the cable pulley 53 and the cable. That is to say, even when the cable pulley 53 is not rotating, it can still guide the cable in the track member 10 and prevent the cable from getting tangled.

[0074] Furthermore, in this embodiment, Figure 1 As shown, the power supply component 70 is installed at one end of the track component 10 along its length, and one end of the constant force reset component 54 is fixed to the other end of the track component 10 along its length, that is, the extended portion is fixed to the track component 10 as described above. The guide component 50 is provided on the side of the slide component 20 away from the power supply component 70, so that when the slide component 20 slides toward the direction closer to the power supply component 70, the length of the first cable portion 71 increases and the length of the second cable portion 72 decreases; conversely, when the slide component 20 slides toward the direction away from the power supply component 70, the length of the first cable portion 71 decreases and the length of the second cable portion 72 increases.

[0075] In a preferred embodiment, such as Figures 2 to 6 As shown, the constant force reset member 54 is installed on the side of the fixed member 51 where the movable pulley 52 is provided, that is, the constant force reset member 54 and the movable pulley 52 are located on the same side of the fixed member 51. The dental chair accessory unit also includes a blocking member 60 installed on the fixed member 51. The blocking member 60 can be formed into a columnar or tubular structure. Specifically, the blocking member 60 is installed on the side of the fixed member 51 opposite to the constant force reset member 54. The blocking member 60 and the cable pulley 53 form a lead-in space 61 for the cable to pass through. The lead-in space 61 is located on the side of the cable pulley 53 away from the slide member 20. Due to the obstruction of the blocking member 60, the cable always slides around the cable pulley 53.

[0076] Furthermore, in this embodiment, as Figure 4 and Figure 6 As shown, a blocking portion protruding radially outward along the end of the cable pulley 53 away from the fixing member 51 is formed at the axial direction, to limit the axial displacement of the cable on the cable pulley 53. Preferably, the blocking member 60 contacts the blocking portion to close the lead space 61, improving the reliability of preventing the cable from slipping off the cable pulley; optionally, a gap is provided between the blocking member 60 and the blocking portion, which is smaller than the diameter of the cable, thus ensuring the effectiveness of the blocking effect of the blocking member 60.

[0077] In this embodiment, as Figures 2 to 8 As shown, the track component 10 includes a central wall portion 11 and two side wall portions 12 located on both sides of the central wall portion 11. Both the central wall portion 11 and the side wall portions 12 are formed into strip-shaped structures. The track component 10 has a U-shaped groove structure with an opening facing the matching component 40 in a cross-section perpendicular to the extension direction; as shown Figure 8As shown, a protruding first mounting plate 13 is provided on one side of the two sidewall portions 12 that are opposite to each other. A first slide rail 101 is formed on the surface of the first mounting plate 13. The first mounting plate 13 and the middle wall portion 11 are preferably arranged in parallel.

[0078] Preferably, at least one of the two first mounting plates 13 is provided with a protrusion 131 at an angle to the plane of the first mounting plate 13 at the end away from the side wall portion 12, that is, the protruding direction of the protrusion 131 is at an angle to the plane of the first mounting plate 13, so as to limit the pulley assembly as described below and prevent the pulley assembly from falling off the first slide rail 101.

[0079] like Figure 8 As shown, two spaced second mounting plates 14 are provided on the surface of the middle wall portion 11 facing the guide assembly 50. The two second mounting plates 14 and the middle wall portion 11 form a second slide rail 102. The movable pulley 52 and the constant force reset member 54, as described above, are provided within the second slide rail 102 formed by the two second mounting plates 14 and the middle wall portion 11.

[0080] Preferably, the two second mounting plates 14 are positioned in the middle of the middle wall portion 11, such that in the track member 10, the second slide rail 102 is positioned in the middle and the first slide rail 101 is positioned on both sides, thus avoiding interference between the guide assembly 50 and the slide member 20 during sliding.

[0081] Furthermore, in this embodiment, as Figure 8 As shown, a protruding support portion 141 is formed on the side of the second mounting plate 14 away from the middle wall portion 11. The support portions 141 on the two second mounting plates 14 are arranged opposite to each other, which reduces the opening size of the second slide rail 102. The movable pulley 52 and the constant force reset member 54 are arranged on the side of the support portion 141 facing the middle wall portion 11 to prevent the constant force reset member 54 and the movable pulley 52 from falling out of the second slide rail 102.

[0082] In this embodiment, the circumferential sidewall of the movable pulley 52 protrudes from the edge of the fixing member 51 in the radial direction; optionally, the fixing member 51 is disposed between the two bearing portions 141.

[0083] Furthermore, in this embodiment, such as Figure 1 , Figure 2 and Figure 8 As shown, a protective plate 15 is also provided on the open side of the track component 10. The protective plate 15 is formed as a strip structure with the opening facing the track component 10 and is fixed on the track component 10. The guide component 50, the first cable part 71 and the second cable part 72 are arranged in the area enclosed by the track component 10 and the protective plate 15 to achieve dust prevention and improve aesthetics.

[0084] Furthermore, in this embodiment, as Figure 9 As shown, the slide block 20 includes a main body 21 and two mating parts 22 located on both sides of the main body 21. The main body 21 is disposed on the side of the protective plate 15 facing outward, and the mating parts 22 are disposed between the protective plate 15 and the side wall 12. The lead wire part 211 as described above can be disposed on the main body 21. Both ends of the mating parts 22 in the extension direction of the first slide rail 101 are provided with pulley groups, and the pulley groups are installed on the opposite sides of the two mating parts 22.

[0085] Specifically, the pulley block includes a first pulley 23 and a second pulley 24. The first pulley 23 is mounted on the surface of the first mounting plate 13 facing the middle wall portion 11, and the second pulley 24 is mounted on the surface of the first mounting plate 13 facing away from the middle wall portion 11, so that both the first pulley 23 and the second pulley 24 can slide on the surface of the first mounting plate 13.

[0086] Preferably, the first pulley 23 and the second pulley 24 have different radial dimensions. The first pulley 23 is larger than the second pulley 24, so that the circumferential sidewall of the first pulley 23 around its axis of rotation protrudes from the end of the mating part 22 away from the main body. This ensures that the mating part 22 will not directly contact the middle wall part 11, thereby ensuring that the slide block 20 moves smoothly.

[0087] Furthermore, in this embodiment, as Figure 6 and Figure 9 As shown, a through groove 223 is provided on the mating part 22. The through groove 223 can be a strip structure, preferably a strip structure extending along the sliding direction of the slide member 20. The through groove 223 corresponds one-to-one with the pulley assembly. The through groove 223 is disposed between the first pulley 23 and the second pulley 24 to divide the area on the mating part 22 where the pulley assembly is installed into a first mounting part 221 and a second mounting part 222. The first pulley 23 is installed in the first mounting part 221, and the second pulley 24 is installed in the second mounting part 222.

[0088] Furthermore, such as Figure 6 and Figure 9As shown, the dental chair unit also includes an adjusting member 30. The adjusting member 30 can be a bolt or screw with a protruding head at one end and a thread on the outer wall of the other end. The adjusting member 30 passes through one of the first mounting part 221 and the second mounting part 222 and is connected to the other of the first mounting part 221 and the second mounting part 222. Preferably, it is a threaded connection, such that one of the first mounting part 221 and the second mounting part 222 has a through hole for the adjusting member 30 to pass through, and the other has a threaded hole. The head of the adjusting member 30 can abut against the end of the first mounting part 221 away from the second mounting part 222 or the end of the second mounting part 222 away from the first mounting part 221. In this way, by adjusting the assembly depth of the adjusting member 30, the distance between the first mounting part 221 and the second mounting part 222 is adjusted, thereby adjusting the distance between the rotation axes of the first pulley 23 and the second pulley 24, so that the first pulley 23 and the second pulley 24 can clamp the first mounting plate 13, so as to ensure that both pulleys can slide on the first mounting plate 13.

[0089] Furthermore, such as Figure 6 and Figure 9 As shown, the mating part 22 is also provided with a partition groove 224. The partition groove 224 is formed into a strip structure and is located on the side of the second mounting part 222 away from the first mounting part 221, so that the second mounting part 222 is formed into a cantilever structure, so as to facilitate the adjustment member 30 to adjust the distance between the first mounting part 221 and the second mounting part 222.

[0090] In this embodiment, as Figure 1 , Figure 2 , Figure 5 and Figure 10 As shown, the dental chair accessory unit also includes a support component 80 disposed between the slide 20 and the accessory component 40. The support component 80 is detachably connected to at least one of the slide 20 and the accessory component 40, which facilitates the replacement of the accessory component 40 to suit the installation requirements of different dental chairs.

[0091] Specifically, such as Figure 10 As shown, the support assembly 80 includes an adapter 81 and a support 82. The adapter 81 is formed into a ring-shaped block structure and is fixedly installed on the slide 20 and / or the matching assembly 40. The support 82 is formed into a tubular structure that is angled to the length direction of the track 10. The support 82 is sleeved on the adapter 81. The adapter 81 is fixed and the adapter 81 and the support 82 are assembled using fasteners such as screws 83. The cable passing through the lead wire 211 passes through the adapter 81 and the support 82 and is connected to the matching assembly 40.

[0092] In the dental chair accessory unit according to the present invention, a first slide and a second slide are formed on the track component; a slide member is slidably engaged with the first slide, and a guide wire portion is provided on the slide member; an accessory component is installed on the slide member, thus realizing that the accessory component is assembled around the dental chair but not connected to the dental chair, thereby allowing people to get on and off the treatment chair from both sides, which is convenient for patients to use. The accessory component can move together with the slide member, so that the accessory component can be moved to the vicinity of the dental chair when in use and removed when not in use, saving the space occupied by the dental chair in the treatment area of ​​the clinic; a power supply component is connected to the accessory component via a cable, and a guide component is slidably engaged with the second slide; a cable leading out from the accessory component passes sequentially through the guide wire portion and the guide component, so that the... The cable in the track component includes a first cable section disposed between the guide component and the slide component, and a second cable section disposed between the guide component and the power supply component. The movable accessory component can drive the slide component to slide along the first slide rail. Under the traction of the cable, the guide component slides along the second slide rail. The displacement of the slide component is different from that of the guide component, which causes the length of one of the first cable section and the second cable section to increase and the length of the other to decrease, while the total length of the first cable section and the second cable section remains unchanged. In this way, the guide component can adjust the length of the first cable section and the second cable section in the track component, avoid the cable from getting tangled when the movable accessory component is moved, and thus ensure that the dental chair accessory unit moves smoothly and meets the usage requirements of the dental chair.

[0093] The dental comprehensive treatment system provided by the present invention includes the above-mentioned dental chair unit, and thus has all the beneficial effects of the dental chair unit, which will not be repeated here.
