Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the following description, together with the accompanying drawings and the embodiments of the present invention, will be made to clearly describe the technical solutions in the embodiments of the present invention, and obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1 and 3, a nursing chair with an elevation memory function comprises a base 2, and a cover 1 is installed on the upper side of the base 2. The lower side of the base 2 is provided with a rotating disk 3 which is suitable for the base 2 to rotate horizontally. Articulated piece 7 has been inlayed in the middle part of base 2, and articulated on the articulated piece 7 have nursing chair support frame 6, and nursing chair body 18 is installed at the top of nursing chair support frame 6. The nursing chair support 6 can rotate in this plane along the hinge point. The top of the outer cover 1 is provided with an opening, and the top end of the nursing chair support frame 6 passes through the opening and protrudes out of the outer cover 1. A spring sliding groove 15 is embedded in the left side of the base 2. A second spring 16 is arranged inside the spring sliding groove 15, the left end of the second spring 16 is connected with a sliding block 17, the middle of the nursing chair supporting frame 6 is hinged with a connecting rod 5, and the other end of the connecting rod 5 is hinged with the sliding block 17. When nursing chair support frame 6 receives pressure leftward, transmit pressure for slider 17 through connecting rod 5, slider 17 gives the effort left of second spring 16, and second spring 16 gives slider 17 reaction force rightwards, makes nursing chair support frame 6 have certain resistance when rotating, avoids appearing rotation by a wide margin, gives the comfortable experience sense of patient on the nursing chair.

As shown in fig. 1 and 2, the middle part of the nursing chair support frame 6 is also hinged with a rack 4, an iron core 13 is embedded in the right side of the base 2, a coil 14 is wound outside the iron core 13, the coil 14 is connected with an external power supply and a switch, and the current on-off condition of the coil 14 can be controlled by the external switch. The upside welding of nursing chair support frame 6 has curb plate 8, installs two gears 9 on the curb plate 8, and rack 4 inserts between two gears 9, and rack 4 and two gears 9 mesh. The gear 9 that is located the downside is provided with screens piece 10, and screens piece 10 embedding is in the inside of base 2, and iron core 13 is located the downside of screens piece 10, and the both sides of iron core 13 all are provided with first spring 12, and the upper end and the screens piece 10 of first spring 12 are connected. The clamping block 10 is provided with slide rails 11 on two sides, and the clamping block 10 is connected with the slide rails 11 in a sliding manner through slide blocks. The upper side of the clamping block 10 is arc concave, and the upper side of the clamping block 10 is provided with meshing teeth. The clamping block 10 is made of iron and is suitable for being adsorbed by the iron core 13.

The working principle is as follows: the initial state of the coil 14 is a power-on state, and at this time, the iron core 13 generates a magnetic force, which is greater than the elastic force of the first spring 12, and the iron core 13 pulls down the upper clamping block 10. When the nursing chair support frame 6 is pressed leftwards, the pressure is transmitted to the sliding block 17 through the connecting rod 5, the sliding block 17 gives a leftwards acting force to the second spring 16, and the second spring 16 gives a rightwards reacting force to the sliding block 17, so that the nursing chair support frame 6 has certain resistance when rotating, and the phenomenon of large-amplitude rotation is avoided. When the nursing chair support frame 6 rotates, the rack 4 drives the gear 9 to rotate together, when the nursing chair support frame rotates to a proper position, a patient using the nursing chair can cut off the current of the coil 14 through an external switch, the magnetic force of the iron core 13 disappears at the moment, the clamping block 10 is jacked up by the first spring 12, the upper side of the clamping block 10 is provided with meshing teeth, the gear 9 is locked through the meshing teeth, and the rack 4 and the nursing chair support frame 6 are locked at the moment. The function of locking the tilt angle is achieved. The horizontal rotation function of the base 2 is realized by the rotating disk 3 arranged at the bottom. The whole nursing chair with the elevation memory function can rotate and lock the memory inclination angle, so that a patient feels more comfortable experience.
