Description

Technical Field

[0001] This utility model relates to the field of dental chair technology, and more specifically, to an integrated dental chair frame and dental chair. Background Technology

[0002] A dental chair is an essential tool for dentists. Unlike regular chairs, dental chairs require a flexible, adjustable mechanism between the seat and backrest. Furthermore, when adjusting from a sitting to a sleeping position, the seat must be tilted upwards at approximately 10 degrees to allow the dentist to treat patients lying flat on the chair.

[0003] The structural and external designs of dental chairs on the market today are becoming increasingly homogenized. Current dental chair frames are complex, use a lot of plastic coverings, resulting in low material costs and high installation and maintenance costs.

[0004] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Utility Model Content

[0005] The purpose of this utility model is to provide an integrated dental treatment chair frame and dental treatment chair. This integrated dental treatment chair frame uses the fewest components to achieve seat rotation and backrest tilting movement, saving plastic covering parts and greatly reducing material costs and installation and maintenance costs.

[0006] This utility model provides an integrated dental treatment chair frame, including a cast frame, arc-shaped guide rails, a backrest rotation mechanism, pulleys, a seat cushion linkage push rod, and a two-way hydraulic cylinder. Arc-shaped guide rails are provided on both the left and right sides inside the cast frame. The pulleys are rotatably connected to the left and right sides of the bottom of the backrest rotation mechanism, with two pulleys correspondingly connected to the arc-shaped guide rails. The two-way hydraulic cylinder is rotatably connected to one end of the cast frame away from the backrest rotation mechanism, and the output end of the two-way hydraulic cylinder is hinged to the bottom of the backrest rotation mechanism. The seat cushion linkage push rod is n-shaped, and its two ends are connected to the two sides of the bottom of the backrest rotation mechanism.

[0007] Using the above technical solution, the backrest rotation mechanism rotates around the pulley under the push of the bidirectional hydraulic cylinder, and moves along the arc-shaped guide rail at the same time, thereby realizing the backrest tilting motion, and realizing the seat frame rotation motion in combination with the connecting shaft between the seat frame and the base; at the same time, the seat cushion linkage push rod connected to the bottom of the backrest rotation mechanism drives the seat cushion linkage push rod to rotate and move while the backrest rotation mechanism rotates and moves, thereby realizing the linkage between the seat cushion and the backrest.

[0008] Furthermore, the casting support frame is a one-piece molded structure.

[0009] Furthermore, lower arc-shaped plates are provided on the left and right sides inside the casting base, and upper arc-shaped plates are connected at intervals above the lower arc-shaped plates, with the arc-shaped guide rail formed between the lower arc-shaped plates and the upper arc-shaped plates.

[0010] Furthermore, the integrated dental treatment chair frame also includes a collar and a rotating shaft. The collar is fitted onto the tail of the bidirectional hydraulic cylinder, and the rotating shaft is connected to both sides of the collar. Connecting holes are provided on both sides of the end of the cast frame away from the backrest rotation mechanism, and the two rotating shafts are rotatably connected in the connecting holes.

[0011] Furthermore, a support wheel is fitted onto the rotating shaft, and the support wheel is located directly below both sides of the seat cushion linkage push rod.

[0012] This utility model also provides a dental treatment chair, which includes the aforementioned integrated dental treatment chair frame.

[0013] This utility model provides an integrated dental treatment chair frame. Driven by a bidirectional hydraulic cylinder, the backrest rotation mechanism rotates around a pulley while simultaneously moving along an arc-shaped guide rail, thus achieving backrest tilting motion. This, combined with the connecting shaft between the seat frame and the base, enables seat frame rotation. Simultaneously, a seat cushion linkage push rod connected to the bottom of the backrest rotation mechanism drives the seat cushion linkage push rod to rotate and move along with the backrest rotation mechanism, thus achieving linkage between the seat cushion and backrest. This utility model uses a minimal number of components to achieve seat rotation and backrest tilting motion; it saves on plastic covering parts; significantly reduces material costs and installation and maintenance costs; and has a simple and clean appearance.
