Description
Technical field
The utility model relates to a kind of therapeutic bed height on-line measurement device.
Background technology
Therapeutic bed many times needs to know the height of therapeutic bed when in use, and must highly adjust it according to actual needs constantly.Adopting the device of the height of measuring therapeutic bed at present is to load onto a tape measure in bed, and tape measure one end is fixed on the base plate of bed, and the other end of tape measure is walked around two axles of pivot arm, also be fixed on the base plate, just form a travelling block structure, when reading height, directly see pointer.This just causes three problems: the one, and precision is not high, and tape measure is on axle, and therapeutic bed is in the process of lifting, and tape measure has axial wobble; The 2nd, not directly perceived, the reading inconvenience; Three because it is the travelling block structure, and the scale of ruler is not a standard, the manufacturing cost height.
The utility model content
The purpose of this utility model provides a kind of easy to use, and reading is directly perceived, and compact conformation is reasonable, and the precision height is made simply therapeutic bed height measuring device with low cost.
The technical solution of the utility model is: a kind of therapeutic bed height measuring device, comprise the therapeutic bed that has pivot arm between base plate and the bed surface, also comprise synchronous band and synchronous pulley, wherein, an end and the described bed surface of band are connected synchronously, the other end is walked around synchronous pulley and is connected with an end of spring, the lower end of the other end of spring and a described pivot arm is connected, synchronous pulley is fixed on the therapeutic bed base plate, from the bed surface to the synchronous pulley one section synchronously band be with vertical synchronously with from the synchronous pulley to the spring one section, and the axle of synchronous pulley is connected with the axle of potentiometer by shaft coupling, this potentiometer is connected with display screen by control module, and this potentiometer will be synchronously passes to described display screen with the resistance variations signal of height change correspondence by described control module.
Described display location is on bed surface.Be convenient to reading.
Principle of work of the present utility model is as follows: therapeutic bed is in lifting, and band drives the synchronous pulley rotation synchronously, and the variation that is about to the therapeutic bed height is converted to the variation of synchronous pulley angle; The rotation of synchronous pulley axle is by the rotation of the axle of shaft coupling drive potentiometer, and the variation that is about to the synchronous pulley angle is converted to the changes in resistance of potentiometer; The electrical signal transfer of the changes in resistance of potentiometer is to control module, and control module is converted into height change again, and the height value electric signal is outputed to display screen.
Technique effect of the present utility model: compact conformation, make simply, with low cost, reading shows with charactron, reads directly perceived; And band is strained by spring always synchronously, keeps certain pulling force, thereby guarantees that the little by little variation on the therapeutic bed height all can reflect on display screen, guarantees the precision of measuring.
