Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a human oral cavity maxillofacial muscle rehabilitation training device, includes mount pad 1 and claw arm 2, and the front end fixed mounting of claw arm 2 holds in the palm groove 3, and mount pad 1 adopts the panel beating to bend and takes shape, holds in the palm the groove 3 be the arc and the outside be equipped with recess 15, during the training, holds in the palm groove 3 from supporting the tooth of the upper and lower row in the oral cavity, the tooth joint is in recess 15.

The gear 7 of two symmetries is connected in the rotation in mount pad 1, the avris fixedly connected with first connecting rod 5 of gear 7, the other end of first connecting rod 5 is articulated with the afterbody of claw arm 2, it has second connecting rod 4 to articulate on mount pad 1, the other end of second connecting rod 4 is articulated with claw arm 2, second connecting rod 4 equals with first connecting rod 5's length, second connecting rod 4 is parallel to each other with first connecting rod 5, two claw arms 2 are at the in-process that opens and shuts, can keep parallel, the movement track of claw arm 2 is simple, and convenient use.

1 sliding connection of mount pad has the round bar 8 that transversely runs through, the tip welding of round bar 8 has rack 6, the upper and lower both sides of rack 6 all are equipped with the tooth, rack 6 and the meshing of gear 7, the removal of rack 6 can drive two gears 7 rotatory, the outer end spiro union of round bar 8 has adjusting nut 9, be connected with spring 10 between adjusting nut 9's inboard and the mount pad 1, spring 10 cup joints on round bar 8, the left end outside distribution of round bar 8 has the external screw thread, spring 10 passes through adjusting nut 9 and applys thrust rightward to round bar 8, drive claw arm 2 outwards expansion, and then hold in the palm groove 3 and apply outside tension.

Adjusting nut 9 includes cylinder 91 and barrel 92, and the right side of cylinder 91 is equipped with the circular shape draw-in groove, and the left end and the draw-in groove joint of barrel 92, and the left end of barrel 92 is equipped with flange ring 93, and the annular spacing collar 94 of right-hand member fixedly connected with of draw-in groove, and the middle part of barrel 92 is equipped with the round hole, and the round hole is with round bar 8's outer wall clearance fit, and the middle part of cylinder 91 is equipped with the screw hole, and the outer wall and the screw hole spiro union of round bar 8, and cylinder 91 can be.

The downside of mount pad 1 has handle 11 through 12 articulated round pin axles, and the upper end side welding of handle 11 has the pin, is equipped with curved spacing hole 13 on the mount pad 1, and the pin runs through spacing hole 13 and rather than sliding connection, and the outer end of pin is equipped with external screw thread and spiro union and has hand screwed nut 14, and during the use, the staff holds handle 11, and after unscrewing hand screwed nut 14, the inclination of the relative mount pad 1 of adjustable handle 11.

The working principle is as follows: when the handle is used, a hand holds the handle 11, the rack 6 is pulled outwards through the round rod 8, the rack 6 drives the two gears 7 to rotate in different directions, the included angle of the two first connecting rods 5 is reduced, and the two bracket 3 are drawn close to the middle, so that the two brackets can extend into the oral cavity of a patient. After the round bar 8 is released by hands, the rack 6 moves inwards to drive the claw arms 2 to be opened, the support grooves 3 are tightly propped against teeth, and the contraction elasticity of the spring 10 applies inwards thrust to the round bar 8 through the adjusting nut 9 to be converted into outwards tension of the two support grooves 3. The distance between the adjusting nut 9 and the mounting seat 1 can be adjusted, the farther the distance between the adjusting nut 9 and the mounting seat 1 is, the longer the spring 10 is pulled, the greater the contraction elastic force of the spring 10 is, the greater the outward tension converted into the bracket 3 is, and otherwise, the smaller the outward tension is, so that the outward tension of the bracket 3 can be adjusted, and the tension is the load of oral cavity training.
