Technical Field

The utility model relates to a display device, it relates to one kind specifically to relate to one kind and raise or reduce the display device that the angle shows to the lift bed.

Background

In medical institutions such as hospitals and clinics, a manual medical bed is often used, that is, the bed is manually lifted to a semi-reclining position. The angle of bed head elevation is required to be different for different disease patients in the field, for example, a shock patient needs 20-30 degrees, a brain trauma patient needs 15-30 degrees, and too low or too high can cause discomfort to the patient or achieve the ideal auxiliary treatment effect. Visual inspection has been used for a long time, and in recent years, a chart or ruler type instrument has been developed for indication, although the instrument is more accurate than visual inspection and plays a positive and effective role in clinic. However, the apparatus is arranged on the side surface of the bed body, and the manual rocker arm is arranged at the bed tail, so that the problems of inconvenient observation, operation and use still exist.

The technical scheme of the utility model as follows: the magnetic sheet type switch comprises magnetic sheets, a direct current power supply and indicator lamps, wherein a chuck provided with a fixed support arm is buckled on a back bedstead at the side of a shaft end connected with the fixed bedstead, a switch consisting of a pull rod, a slide block with the end part of the pull rod moving along double rails in a terminal board shell and a terminal on the terminal board is driven by the support arm on the chuck, and the switch is connected with a group of displays connected in parallel on the direct current power supply and formed by a plurality of indicator lamps.

The chuck is a connecting piece integrally formed by a rectangle and a semicircle, a clamping sleeve formed by a bayonet formed by sheet bodies which are distributed at an inward 90-degree angle and have the same width as the back bedstead is arranged at the corresponding side of the rectangular part of the connecting piece, a through hole corresponding to a bolt at the end side of the connecting shaft is arranged on the clamping sleeve, the through hole is larger than the bolt, and a connecting component formed by a support arm is further fixed at the outer side of the clamping sleeve.

The pull rod is a metal rod bent into a right angle, one end of the pull rod is arranged in the micropore on the support arm, and the other end of the pull rod is fixed with the sliding block.

The slider is a metal body with the length larger than the distance between two rows of terminals arranged at the bottom of the insulator, and through holes which are transversely symmetrical are arranged on the insulator part.

The position of each terminal in the terminals on the terminal board corresponds to the angle of the back bedstead rotating along the connecting shaft.

The diameter of the upper semicircle of the cutting sleeve of the chuck is matched with the width of the back bedstead.

The utility model discloses owing to taken the structure, especially set up the pull rod that is driven by the support arm on the chuck, become the linear motion of the terminal slider of pull rod with the pitch arc motion of chuck, come the control switch-on again by the slider and correspond the power of being connected with each pilot lamp of display, show angle of rise. The purpose of the invention is reliably realized. The novel water-saving water dispenser has the advantages of novel conception, reasonable structural design, convenience and flexibility in use, suitability for popularization and the like.

Detailed Description

The medical lifting bed lifting angle display device shown in fig. 1-3 is a back bedstead 1 connected with the fixed bedstead and provided with a chuck 2, wherein the chuck 2 is a connecting member consisting of a cutting sleeve and a support arm 3 fixed on the outer side of the cutting sleeve. The clamping sleeve is formed by integrating a rectangle and a semicircle to form a connecting piece, symmetrical right-angle bayonets which are formed by sheet bodies which are distributed inwards by 90 degrees and have the same width with the thickness of the back bedstead 1 are arranged on the corresponding side of the rectangular part of the connecting piece, through holes which correspond to bolts on the end side of the connecting shaft are arranged on the connecting piece provided with the bayonets, and the through holes are larger than the bolts and are covered outside the connecting piece. The support arm 3 is a strip-shaped fixed connecting sheet, and micropores are uniformly distributed on the connecting sheet; the pull rod 4 is a metal rod bent at a right angle, and one end of the pull rod 4 passes through the micropore on the support arm 3 and is suspended in the micropore, generally, the micropore close to the ferrule on the support arm 3, such as the first micropore and the second micropore. And when mounted, the pull rod 4 is vertically arranged with the support arm 3 on the chuck 2 (the position in the figure is only schematically expressed and is not accurate enough). The other end of the pull rod 4 is arranged in the outer shell of the terminal board 6 and fixed with the slide block 5. Said slider 5 can slide inside the outer casing of the terminal plate 6 along a double track 7 fixed to the corresponding side of the casing. The slider 5 is formed by arranging a metal body with the length larger than the distance between two rows of terminals at the bottom of the insulator and arranging transversely symmetrical through holes on the insulator. The double tracks 7 pass through symmetrical through holes of the sliding block 5 to support the sliding block 5 to slide on the fixed tracks. The slide block 5, the terminal on the terminal board 6 and the pull rod 4 form a switch, and a group of displays 8 which are connected in parallel on a direct current power supply 9 and are composed of a plurality of indicator lamps are connected through the switch. The positions of the terminals on the terminal board 6 correspond to the rotation angles of the back bedstead 1 along the connecting shaft one by one. The distance between each terminal of the circuit board is measured through the protractor, the angle distance is calculated, and the accuracy is guaranteed.

When the device is installed, the terminal board 6, the double rails 7 and the sliders 5 on the double rails 7 in the terminal board shell and the outer shell are integrally fixed on the fixed bed frame part through the magnetic sheet arranged outside, and the display 8 is fixed on a bed body (such as a bed tail) which is easy to observe through another magnetic sheet. And simultaneously, the direct current power supply is switched on. When the device works, the back bed frame 1 starts to rotate and move by taking the connecting shaft as the shaft along with the swinging of the crank, and the back bed frame 1 is lifted or lowered along with the rotation. In the process, the support arm 3 on the chuck 2 tends to push the pull rod 4 placed in the micropore, the rotation, namely arc motion, of the chuck 2 is changed into the linear motion of the slide block 5 at the tail end of the pull rod 4, and therefore the slide block 5 fixed at the end part of the pull rod 4 slides on the double track 7. The slider 5 contacts with one of the terminals, and the indicator corresponding to the display 8 is turned on, and the positions of the terminals in the terminal board are opposite to the rotation angles of the back bed frame 1 along the connecting shaft, so that the indicator on the display 8 respectively shows different angles of 10 degrees, 20 degrees, 30 degrees and 40 degrees if the angle difference of each terminal is 10 degrees. Fig. 1 shows the back frame 1 in a position raised by 40. Because the utility model discloses can take the magnetic sheet to fix respectively with switch and display 8, in addition the convenience that chuck 2 and back bedstead 1's lock and pull rod 4 put into, very easy dismouting is fixed for a device can satisfy the use of a plurality of medical lift beds, saves the resource.
