Detailed description of the invention

Fig. 1 is the structural schematic diagram from the foot pad and chair frame main body connecting portion for looking up the dental chair that angle is seen；

Fig. 2 is the longitudinal cross-section structural schematic diagram of foot pad and cushion；

Fig. 3 is that foot pad slides into schematic diagram when leaving cushion highest distance position.

Specific embodiment

The utility model is described more fully with reference to the accompanying drawings for the ease of understanding the utility model,.Attached drawing In give the better embodiment of the utility model.But the utility model can be realized in many different forms, and It is not limited to embodiments described herein.The purpose of providing these embodiments is that making the disclosure reason to the utility model What is solved is more thorough and comprehensive.

Referring also to Fig. 1, Fig. 2, the foot pad telescoping mechanism of dental chair include cushion 1 and foot pad 2, and cushion 1 is fixed on chair frame In main body 3 (to keep view clear, Fig. 1 does not draw cushion).Chair frame main body 3 is connected with towards the support frame stretched out below foot pad 2.Branch Support is a U-tube 4.Two of U-tube 4 are connected to chair frame main body 3 by screw 6 in the parallel tube segments 5 of arc line shaped The left and right sides.Foot pad 2 is located at the upper surface of U-tube 4.Pipe clamp 7 has been ridden respectively in two parallel tube segments 5 of U-tube 4, has been managed Card 7 is fixed on the bottom of foot pad 2 by screw and can be slided along the pipeline section 5 ridden, thus constitutes the cunning of foot pad 2 Yu U-tube 4 Dynamic connection, foot pad 2 can be slided along two parallel tube segments 5 of U-tube.

Referring to fig. 2, the edge of foot pad 2 being connected with cushion 1 is equipped with the flange 8 stretched out towards cushion 1, and the pad of flange 8 is being sat Below pad 1.As shown in figure 3, flange 8 makes to leave the most amphi position of cushion 1 when foot pad 2 slides into towards the length that cushion 1 stretches out When setting, still there is the pad of ribbed portion 8 below cushion 1, so that without up and down between the foot pad 2 and cushion 1 after elongation The gap of perforation.

As preferred forms, referring also to Fig. 1, Fig. 2, Fig. 3, the bottom of foot pad 2 sets that there are three determining of being recessed upwards Position slot 9 (locating slot is blocked in Fig. 1 and can not see), three locating slots 9 are arranged side by side along the direction that foot pad 2 slides. When foot pad 2 is slided along U-tube, the horizontal segment 10 of U-tube 4 being located between two parallel tube segments 5 falls into and skids off one by one Each locating slot 9.As shown in Fig. 2, horizontal segment 10 is trapped in distance and sits when foot pad 2 slides into the position apart from 1 most proximal end of cushion In the nearest locating slot 9 of pad 1.As shown in figure 3, horizontal segment 10 is trapped in when foot pad 2 slides into the position farthest apart from cushion 1 In the locating slot 9 farthest apart from cushion 1.Locating slot 9 enables foot pad 2 to be located in scheduled several positions, enables use more square Just.Since the horizontal segment 10 of U-tube 4 has certain dipping and heaving when falling into and skidding off each locating slot 9 one by one, because This, entire U-tube 4 preferably swings up and down activity around what screw 6 had a certain angle.

As preferred forms, referring to fig. 2, aluminium sheet 11 is equipped with inside foot pad 2.Aluminium sheet 11 plays reinforcement effect, installing pipe The screw of card 7 may be connected on aluminium sheet 11.

As preferred forms, the bottom of foot pad 2 is polyurethane sheet, referred to as PU plate.

Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed, But it cannot be understood as the limitations to utility model patent range.For those of ordinary skill in the art, exist Under the premise of not departing from the utility model design, various modifications and improvements can be made, these belong to the utility model Protection scope.
