Detailed Description
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
By figure 1 to 4 and give, including control box 1, axial coil spring 2 about being equipped with in the control box 1, the free end of coil spring 2 is equipped with horizontal chi 3, the left side wall of control box 1 is run through to the free end of horizontal chi 3, the free end of horizontal chi 3 articulates there is vertical chi 4 of direction from top to bottom and being located its rear, vertical chi 4 rear end is equipped with the fixed plate 5 of rectangle, the four corners department of fixed plate 5 all is equipped with stopper 6, fixed plate 5 can be dismantled with the left side wall of control box 1 and be connected, the card hole 7 that link up around having seted up on the horizontal chi 3, the free end of vertical chi 4 is equipped with the card axle 8 that can insert in the card hole 7.
In order to clarify the measured value and range, the transverse ruler 3 and the longitudinal ruler 4 are respectively provided with scale values which are uniformly distributed along the length direction of the transverse ruler and the longitudinal ruler.
In order to enable the fixing plate 5 to be detachably connected with the left side wall of the control box 1, the left side and the right side of the fixing plate 5 are respectively provided with a clamping groove 9 which is through from front to back, and the upper side and the lower side of the left end face of the control box 1 are respectively provided with a clamping block 10 which can be inserted into the clamping groove 9.
In order to limit the length of the transverse ruler 3, positioning holes 11 are uniformly distributed along the length direction of the transverse ruler 3, and a cross shaft 12 capable of being inserted into the positioning holes 11 is connected to the front side wall of the control box 1 in a sliding mode.
In order to facilitate the resetting of the cross shaft 12, the cross shaft 12 is sleeved with a spring positioned between the stepped surface and the front side wall of the control box 1.
In order to read the numerical value, the upper side of the fixing plate 5 is provided with a pointer 13 positioned above the transverse ruler 3.
When the utility model is used, the initial state is that the clamping shaft 8 is inserted into the clamping hole 7, the transverse ruler 3 is overlapped with the longitudinal ruler 4 and is contained in the control box 1, the clamping block 10 is matched with the clamping groove 9, and the fixing plate 5 is kept in contact with the left side wall of the control box 1;
firstly pressing the two clamping blocks 10 to move the clamping blocks relatively, taking the fixing plate 5 off the control box 1, pulling the cross shaft 12 forwards and compressing the spring to prevent the cross shaft 12 from being inserted into the positioning hole 11 in the process of pulling the transverse ruler 3, pulling the fixing plate 5 leftwards, driving the transverse ruler 3 to extend out of the control box 1 by the fixing plate 5 until the longitudinal ruler 4 completely extends out of the control box 1, taking the clamping shaft 8 out of the clamping hole 7, slightly misplacing the transverse ruler 3 forwards to enable the limiting blocks 6 to pass through from the rear side, clockwise rotating the fixing plate 5 by 90 degrees to enable the transverse ruler 3 to be positioned between the two vertically corresponding limiting blocks 6 on the right side, keeping the longitudinal ruler 4 vertical to the transverse ruler 3, pressing the longitudinal ruler 4 to the skin of a patient to measure the longitudinal distance of the leg of the patient, winding the transverse ruler 3 around the leg of the patient for one circle, loosening the cross shaft 12, and inserting the cross shaft 12 into the positioning hole 11 under the action of the spring, the length of the transverse ruler 3 extending out of the control box 1 is unchanged, the reading pointed by the pointer 13 is observed, the leg circumference of the leg of the patient is measured, the fixed measurement is convenient, and the data is accurate in correspondence;
