Description

Technical Field

[0001] The utility model belongs to the technical field of tooth making, and in particular relates to a tray support frame. Background Art

[0002] In the tooth making process, plaster material needs to be filled in the dental impression tray, and the working model is formed by the solidification of the plaster material, and then the tooth making operation is completed on the model. At present, the dental impression tray filled with plaster is mainly placed on the platform for a period of time to wait for the plaster material to completely solidify. During the static process, the free end of the dental impression tray will be stressed, which causes the oral impression material beyond the edge of the tray to be easily deformed, which ultimately affects the quality of the finished teeth. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a tray support frame.

[0004] The utility model is implemented as follows: a tray support frame comprises a frame body, a plurality of support plates are horizontally fixedly arranged in the frame body, a bottom plate is horizontally fixedly arranged at the lower end of the frame body, a pressure plate is horizontally arranged above the support plate, the tray handle is clamped between the pressure plate and the support plate, to prevent the free end of the tray from being stressed, thereby avoiding deformation of the oral impression material, a plurality of screws are vertically and evenly fixedly arranged at the lower end of the pressure plate, a plurality of through holes are evenly opened on the support plate, the positions of the screws and the through holes correspond to each other and the sizes match, the screws pass through the through holes and nuts are tightly sleeved on the screws, the pressure plate and the support plate are tightly connected together by the screws and nuts, thereby ensuring that the tray handle is stably and reliably clamped between the pressure plate and the support plate, to prevent loosening and falling accidents.

[0005] Preferably, a pull handle is fixedly provided at the middle position of the upper end of the pressing plate, so as to apply force to lift the pressing plate, thereby clamping the tray handle between the pressing plate and the supporting plate, and then releasing the pull handle to let the pressing plate fall.

[0006] Preferably, the width of the bottom plate is 1.5 to 2.5 times the width of the support plate. When a plurality of dental impression trays are placed on the support frame, the support frame is stably supported to prevent the support frame from tipping over due to the forward movement of the center of gravity of the support frame.

[0007] Preferably, the length of the pressing plate is the same as the length of the supporting plate, and the width of the pressing plate is not greater than the width of the supporting plate.

[0008] Preferably, the support plate and the pressure plate are made of stainless steel, which is strong and durable, has a long service life, and is not prone to deformation.

[0009] The beneficial effects of the utility model are as follows: the utility model has a reasonable structural design, and the pressing plate and the supporting plate are tightly connected together by the screw and the nut, thereby ensuring that the tray handle is stably and reliably clamped between the pressing plate and the supporting plate, which not only avoids the occurrence of loosening and falling accidents, but also prevents the free end of the tray from being stressed, thereby avoiding the deformation of the oral impression material and ensuring the reliable quality of the finished teeth.

[0014] In order to more clearly understand the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0015] like Figure 1-3 A tray support frame shown in the figure comprises a frame 1, wherein three layers of support plates 2 are fixedly arranged horizontally in the frame 1, and a bottom plate 3 is fixedly arranged horizontally at the lower end of the frame 1, and the width of the bottom plate 3 is twice the width of the support plate 2. When multiple dental impression trays are placed on the support frame, the support frame is stably supported to prevent the support frame from tipping over due to the forward movement of the center of gravity of the support frame. A pressing plate 4 is horizontally arranged above the support plate 2, and the tray handle is clamped between the pressing plate 4 and the support plate 2 to prevent the free end of the tray from being stressed, thereby avoiding the deformation of the oral impression material. The length of the pressing plate 4 is the same as the length of the support plate 2, and the width of the pressing plate 4 is not greater than the width of the support plate 2. A pull handle 8 is fixedly arranged at the middle position of the upper end of the pressing plate 4, which is convenient for applying force to lift the pressing plate 4, thereby clamping the tray handle between the pressing plate 4 and the support plate 2, and then releasing the pull handle 8 to make the pressing plate 4 fall. Three screws 5 are vertically and evenly fixed on the lower end of the pressure plate 4, and three through holes 6 are evenly opened on the support plate 2. The screws 5 correspond to the positions of the through holes 6 and are of the same size. The screws 5 pass through the through holes 6 and nuts 7 are tightly sleeved on the screws 5. The pressure plate 4 and the support plate 2 are tightly connected together by the screws 5 and the nuts 7, thereby ensuring that the pallet handle is stably and reliably clamped between the pressure plate 4 and the support plate 2 to prevent loosening and falling accidents.

[0016] The support plate 2 and the pressure plate 4 are made of stainless steel, which is strong and durable, has a long service life, and is not prone to deformation.

[0017] The above description is only a preferred embodiment of the present utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the scope of the present utility model patent application are included in the scope of the present utility model patent application.
