[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example

[0026] Please see Figure 1-3 An adjustable prenatal examination chair includes a base plate 1 and a prenatal examination chair 3. The bottom end of the base plate 1 is provided with a moving mechanism, which includes four moving wheels 2. The four moving wheels 2 are symmetrically arranged at the bottom end of the base plate 1, and the arrangement of the four moving wheels 2 facilitates the movement of the base plate 1.

[0027] Please see Figure 1-3 The prenatal examination chair 3 is height-adjustable via a height adjustment mechanism, which includes two electric cylinders 4. The two electric cylinders 4 are fixedly installed at the bottom of the prenatal examination chair 3, with the ends of each cylinder 4 away from the chair 3 fixedly connected to the base plate 1. Activating the two electric cylinders 4 adjusts the height of the prenatal examination chair 3. Two first telescopic rods 5 are symmetrically fixedly installed at the bottom of the prenatal examination chair 3, with the ends of each first telescopic rod 5 away from the chair 3 fixedly connected to the base plate 1. A leg support 6 is fixedly installed on the prenatal examination chair 3, with two second telescopic rods 7 symmetrically fixedly installed at the bottom of the leg support 6. The other ends of each second telescopic rod 7 are fixedly connected to the base plate 1. As the prenatal examination chair 3 moves, it simultaneously moves the leg support 6. The cooperation of the two first telescopic rods 5 and the two second telescopic rods 7 makes the prenatal examination chair 3 more stable during movement. A backrest 8 is rotatably installed on the prenatal examination chair 3.

[0028] Please see Figure 1-4The chair back 8 is adjusted via a power mechanism, which includes a motor 11. The motor 11 is fixedly installed on the outer side wall of the prenatal examination chair 3. A rotating shaft 12 is fixedly installed at the output end of the motor 11. A rotating groove is provided on the prenatal examination chair 3. The rotating shaft 12 is rotatably connected to the rotating groove. By starting the motor 11, the motor 11 provides power to drive the rotating shaft 12 to rotate. The rotating shaft 12 is fixedly connected to the chair back 8, thereby driving the chair back 8 to rotate. A first connecting rod 9 and a second connecting rod 10 are rotatably connected to the prenatal examination chair 3 and the chair back 8, respectively. One end of the first connecting rod 9 and the second connecting rod 10 are rotatably connected. An emergency bell 17 is provided on one of the second connecting rods 10.

[0029] Please see Figure 1-4 The chair back 8 is supported and stabilized by a support mechanism, which includes two fixed plates 13. The two fixed plates 13 are symmetrically fixed on the prenatal chair 3. Slide plates 14 are slidably installed inside the two fixed plates 13. The two slide plates 14 are connected by a connecting shaft. A support plate 15 is rotatably installed on the connecting shaft. A hinge seat 16 is fixedly installed on the chair back 8. The hinge seat 16 and the support plate 15 are rotatably connected. When the chair back 8 moves, the two slide plates 14 slide on the two fixed plates 13 respectively through the cooperation of the support plate 15, so that the chair back 8 is more stable when it moves.

[0030] Please see Figure 1 A protective cover 20 is fixedly installed on the outer wall of the prenatal examination chair 3. The motor 11 is located inside the protective cover 20. The installation of the protective cover 20 protects the motor 11.

[0031] Please see Figure 1 The base plate 1 is equipped with an anti-slip mat 21, which increases the friction and prevents pregnant women from slipping.

[0032] In summary, when using this adjustable prenatal examination chair, the height of the chair 3 is adjusted by activating two electric cylinders 4. Simultaneously, the leg support 6 moves with the chair 3. The coordination of the two first telescopic rods 5 and the two second telescopic rods 7 ensures greater stability during movement. The motor 11, a commercially available device known to those skilled in the art, is activated. We are simply using it without making any structural or functional improvements, which will not be detailed here. The motor is equipped with a matching control switch, the installation position of which depends on… The chair is designed to be adjusted according to actual usage needs, making it easy for operators to control. The motor 11 provides power to drive the rotating shaft 12 to rotate, which in turn drives the chair back 8 to rotate. As the chair back 8 moves, the support plate 15 drives the two sliding plates 14 to slide on the two fixed plates 13, making the movement of the chair back 8 more stable. This allows the chair to be adjusted according to the needs of the mother, making her more comfortable. In case of special circumstances requiring assistance, the emergency bell 17 can be pressed to call for help. The emergency bell 17 is connected to external equipment for timely emergency treatment.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
