Description

Technical Field

[0001] The invention relates to the field of dentistry, and in particular to a multifunctional dental binding bed. Background Art

[0002] The pediatric dental treatment table is a specially designed dental treatment equipment specifically for children's dental treatment. Because children's oral structure and development are different from adults, they may need special attention and care.

[0003] When children are undergoing dental treatment, they often twist on the dental bed because they are afraid of pain and resist treatment. Therefore, children's willful twisting on the dental bed will affect the normal treatment operations of the dentist, and in severe cases, it will cause secondary injuries to the children. Therefore, when children are undergoing dental treatment, a dental binding bed is used to restrict the children to the surface of the dental bed, which is conducive to the dentist to perform quick treatment.

[0004] However, the existing dental binding bed can only bind the child's body but cannot restrict the child's head due to its single function during use. This requires a special person to support and limit the child's head. Therefore, adding auxiliary personnel will occupy the dentist's treatment space and it is not convenient to divert the child's attention. Therefore, the child focuses on the pain caused by the treatment, which is not conducive to the dentist's treatment. Summary of the invention

[0050] The working principle of the present invention is as follows: when treating children's teeth, first let the child lie on the upper surface of the dental binding bed, then start the driving motor 28 to drive the transmission shaft 22 at one end to rotate, and at the same time, one end of the driving motor 28 will drive the other group of transmission shafts 22 in meshing connection to rotate synchronously through the transmission shaft 22, so the two groups of transmission shafts 22 respectively and synchronously drive the transmission chains 26 on their respective outer surfaces to rotate, and the rotation of the transmission chain 26 will drive the two groups of limiting frames 21 to synchronously flip 180 degrees in the opposite direction through the transmission sprocket 27, so that the limiting frames 21 slowly and uniformly flip to the upper surface of the back pad 210 and clamp on the outer surface of the child's shoulders and arms, so that the upper body of the child is restricted to the upper surface of the back pad 210, wherein the limiting frames While flipping, the connecting rope 12 connected at one end will drive and pull the two sets of head limiting side plates 113 to slide toward the center of the upper surface of the head pad 11 until the side of the head limiting side plates 113 contacts the child's head, and in the process of the head limiting side plates 113 driving the limiting block 13 at the bottom to slide, the inclined surface of one end of the transmission gear plate 19 will be squeezed, so that one end of the transmission gear plate 19 is pressed and slides, driving the transmission gear 17 and the limiting rod 18 engaged at one end to rotate synchronously, and the limiting rod 18 will drive the lighting lamp 110 at one end to flip 180 degrees synchronously, so that the lighting lamp 110 illuminates the child's teeth above the child's head, which is convenient for the dentist to treat the child's teeth, and then press the forehead limiting plate 113. The top of 11 descends and contacts the forehead of the child, thereby limiting the sides and top of the child's head to prevent the child's head from shaking up and down and left and right and affecting the treatment efficiency. Then the leg binding belt 34 is pulled to tie the child's legs, and then the display 44 is turned on for the child to watch the video to divert his attention. The first hydraulic cylinder 42 and the second hydraulic cylinder 43 can also be controlled to rise and fall, and the height and inclination of the trunk limiting component 2 and the leg limiting component 3 can be controlled. The height of the head limiting component 1 can also be adjusted according to the height and fatness of the child. When adjusting the height of the head limiting component 1, the threaded rod 15 can be rotated to be threadedly connected with the threaded hole 24, so as to drive the head limiting component 1 to rise and fall at one end of the trunk limiting component 2. However, when the treatment is completed, the forehead limit plate 111 is pulled up, and then the driving motor 28 is controlled to rotate in the opposite direction, driving the limit frames 21 on both sides to reset and flip over, and at the same time, the second reset spring located inside the limit slide 112 will push the two sets of limit blocks 13 to slide away from each other and reset, and the limit rod 18 will push the transmission gear plate 19 to reset and slide, and at the same time drive the lighting lamp 110 to reset and flip downward, and then remove the leg binding straps 34, so that the child can leave the dental binding bed, and through the coordinated operation of the head limit component 1, the torso limit component 2, the leg limit component 3 and the bottom support component 4, it can provide a variety of auxiliary functions during the dental treatment process, thereby improving the dentist's treatment efficiency.
