Abstract
The utility model relates to a kind of single track chute drive mechanism of pregnant woman childbirth medical lecture model, comprise support, motor, childbirth mechanism shell, support is provided with the drive lead screw of horizontal positioned, connected by fixed cover and surface bearing at the other end of drive lead screw, drive lead screw is set with transmission nut, transmission nut is fixedly connected with sliding panel, sliding panel is provided with childbirth mechanism shell, be provided with rolling bearing bottom sliding panel, rolling bearing is positioned on single track coulisse that support is arranged.The utility model has the advantages that by screw nut driving mechanism, the very big intensity improving single track chute.Change thus ensure that the axis hole concentricity at screw mandrel two ends, bearing sliding panel takes four rolling bearing guide-localizations, reduce the friction produced when running and resistance greatly, thus it is quite steady to make it run.Make its screw nut driving Impact direction and childbirth mechanism run stressed parallel point-blank.Make it quite steady in stability, increase the service life greatly.
Description
Technical field
The utility model relates to a kind of drive mechanism, particularly a kind of single track chute drive mechanism of pregnant woman childbirth medical lecture model.
Background technology
In current pregnant woman childbirth analogy model medical teaching industry at home, the product of domestic production is all copy external a kind of pregnant woman childbirth model mechanism to carry out childbirth teaching, what this mechanism adopted is a kind of monolateral screw nut driving mode of double track of rectangular tubular, rear extreme influence rigidity intensity processed by rectangular tubular guide rail, its stability is made after assembling, fastness extreme difference, screw rod transmission and childbirth mechanism driving center of effort both not parallel not point-blank yet, cause monolateral stressed from face, in use due to transmission discontinuity equalization, resistance is excessive, run not steady, cause mechanism run shake and noise magnitude very big, run difficulty and affect the serviceable life of product and the effect of teaching demonstration greatly.Therefore urgently the drive mechanism of existing childbirth mechanism is improved.
Summary of the invention
The purpose of this utility model is the problems referred to above existing for the monolateral screw nut driving mode of double track of the drive mechanism employing rectangular tubular solving pregnant woman childbirth model in prior art, provides a kind of single track chute drive mechanism of pregnant woman childbirth medical lecture model.The utility model designs a kind of single track chute drive mechanism of pregnant woman childbirth medical lecture model, comprise support, motor, childbirth mechanism shell, it is characterized in that: the drive lead screw being provided with horizontal positioned on support, one end of drive lead screw is by being fixed with gear, this gear engages with generator shaft gear, connected by fixed cover and surface bearing at the other end of drive lead screw, drive lead screw is set with transmission nut, transmission nut is fixedly connected with sliding panel, sliding panel is provided with childbirth mechanism shell, rolling bearing is provided with bottom sliding panel, rolling bearing is positioned on single track coulisse that support is arranged.The rolling bearing arranged bottom sliding panel has four, two groups, front and back, and often group left and right is arranged on bottom sliding panel, on two single track coulisses that four rolling bearings in two groups, front and back divide left and right to be positioned at left and right setting.The utility model has the advantages that the kind of drive be made up of screw nut driving mechanism.Single track coulisse adopts integral Al-alloy materials processing, the very big intensity improving single track chute.Change thus ensure that the axis hole concentricity at screw mandrel two ends, bearing sliding panel takes four rolling bearing guide-localizations, reduce the friction produced when running and resistance greatly, thus it is quite steady to make it run.Make its screw nut driving Impact direction and childbirth mechanism run stressed parallel point-blank.Make it quite steady in stability, increase the service life greatly.
Accompanying drawing explanation
Accompanying drawing 1 is section of structure of the present utility model, and accompanying drawing 2 is the vertical view of Fig. 1.
Embodiment
A kind of single track chute drive mechanism of pregnant woman childbirth medical lecture model in figure, comprise support 1, motor 2, childbirth mechanism shell 3, it is characterized in that: the drive lead screw 4 being provided with horizontal positioned on support, one end of drive lead screw is by being fixed with gear 5, this gear engages with generator shaft gear 6, connected by fixed cover 7 and surface bearing 8 at the other end of drive lead screw, drive lead screw is set with transmission nut 9, transmission nut is fixedly connected with sliding panel 10, sliding panel is provided with childbirth mechanism shell, rolling bearing 11 is provided with bottom sliding panel, rolling bearing is positioned on single track coulisse 12 that support is arranged.The rolling bearing arranged bottom sliding panel has four, two groups, front and back, and often group left and right is arranged on bottom sliding panel, on two single track coulisses that four rolling bearings in two groups, front and back divide left and right to be positioned at left and right setting.
In using, motor (DC24V, 35W direct current generator) is as power, make drive lead screw rotate after energising, thus drive transmission nut translation, sliding panel translation thereupon, be arranged on the whole childbirth mechanism shell moving linearly on sliding panel, thus reach the operational process of childbirth production.And four rolling bearings be arranged on bottom sliding panel operationally coordinate with single track sliding slot board, ensure its good guidance quality and stability, make operation Impact direction and childbirth mechanism runs stressed parallel point-blank, thus solve mechanism run imbalance, the problem that resistance is larger.
