By rotating the third screw 602 and the T-shaped slider 603 threadedly in the opposite direction, the T-shaped slider 603 can be driven to drive the guide block 601 and the holding rod 60 to move in the opposite direction. It is convenient to drive the holding rod 60 to move, and stopping the rotation of the third screw 602 and the T-shaped slider 603 threadedly can form a self-locking, thereby fixing the holding rod 60, which is convenient.

[0060] See also Figure 1 , Figure 3 , Figure 8 and Fig. 9 In one embodiment, the support mechanism also includes an anti-tilt mechanism, which includes a blocking rod 70 and a locking assembly. The bottom ends of the two groups of support plates 50 away from the ends of the guide seat 20 are vertically provided with connecting shafts 504. The blocking rods 70 are rotatably provided on the two groups of connecting shafts 504. The locking assemblies are connected between the blocking rods 70 and the connecting shafts 504. The locking assemblies are used to fix the blocking rods 70 when the blocking rods 70 are under pressure.

[0061] In the above embodiment, horizontal force is applied to the two sets of baffle rods 70 to rotate the two sets of baffle rods 70 to the front of the elderly person's body and be located between the two sets of support plates 50. When the elderly person leans forward and applies pressure to the two sets of baffle rods 70, the locking assembly can fix the two sets of baffle rods 70, so that the two sets of baffle rods 70 block the body, thereby preventing the elderly person from accidentally leaning forward and falling, further improving the safety of the elderly person's use of the toilet. When not in use, the two sets of baffle rods 70 can be stored by applying horizontal force to the two sets of baffle rods 70 to rotate the two sets of support plates 50, which is convenient for storing the two sets of baffle rods 70.

[0062] Specifically in the above embodiment, the locking assembly includes a limit plate 701 and a spring 702; a connecting hole 705 is opened at one end of the baffle rod 70, and the connecting hole 705 is sleeved on the connecting shaft 504. The limit plate 701 is coaxially arranged at the bottom end of the connecting shaft 504. The spring 702 is sleeved on the connecting shaft 504, and the two ends are respectively against the limit plate 701 and the baffle rod 70. A plurality of groups of fixed plug blocks 703 are evenly arranged around the circumference of the connecting shaft 504 at the bottom end of the baffle rod 70. A plurality of groups of fixed slots 704 are evenly arranged along the circumference of the limit plate 701, and the plurality of groups of fixed plug blocks 703 can be inserted into the plurality of groups of fixed slots 704.

[0063] When the baffle rod 70 is under pressure, the baffle rod 70 moves downward to squeeze the spring 702 and allow the multiple groups of fixed blocks 703 to pass through the multiple groups of fixed slots 704. At this time, the baffle rod 70 can be fixed. When the pressure on the baffle rod 70 is released, the reaction force of the spring 702 causes the baffle rod 70 to move upward and separate the multiple groups of fixed blocks 703 from the multiple groups of fixed slots 704. At this time, the baffle rod 70 can be rotated, and it is convenient to fix and rotate the baffle rod 70.

[0064] The specific implementation of the above-mentioned multifunctional squat toilet for the elderly is as follows:

[0065] When in use, the buttocks and back are placed against the seat cushion 201 and the backrest 103 respectively, and the first screw 30 is driven to rotate by controlling the motor 301. The first screw 30 rotates and matches with the thread of the guide seat 20 to drive the guide seat 20 to move downward. The guide seat 20 moves downward to drive the seat cushion 201, the worm 40 and the worm wheel 401 to move downward. The worm 40 moves downward to make the guide hemisphere 405 slide along the spiral guide groove 403. The guide hemisphere 405 slides along the spiral guide groove 403 to drive the worm 40 to rotate. The worm 40 rotates and meshes with the worm wheel 401 to drive the worm wheel 401 to rotate clockwise. The worm wheel 401 rotates clockwise to drive the seat cushion 201 to rotate clockwise. When the guide seat 20 moves downward to the sitting height, the guide hemisphere 405 is located at the connecting point of the spiral guide groove 403 and the limit guide groove 404, and the seat cushion 201 is horizontal, so that the seat cushion 201 supports the elderly to switch from a standing position to a sitting position. When the guide seat 20 continues to move downward, the guide seat 20 drives the seat cushion 201 to move downward, and causes the guide hemisphere 405 to slide downward along the limit guide groove 404. At this time, the worm 40 stops rotating. The worm 40 stops rotating and cooperates with the worm wheel 401 to form a self-locking function to fix the rotation of the seat cushion 201, so that the seat cushion 201 maintains a horizontal state and moves downward. The horizontal downward movement of the seat cushion 201 can support the elderly to switch from a sitting position to a squatting position.

[0066] When the guide seat 20 moves upward to the height of the seat, the seat cushion 201 supports the elderly person to change from a squatting position to a sitting position. When the guide seat 20 continues to move upward to a height higher than the seat height, the guide hemisphere 405 slides in the opposite direction along the spiral guide groove 403, thereby causing the worm 40 to rotate in the opposite direction. The worm 40 rotates in the opposite direction and engages with the worm wheel 401 to drive the worm wheel 401 to rotate counterclockwise. The counterclockwise rotation of the worm wheel 401 can drive the seat cushion 201 to rotate counterclockwise. The seat cushion 201 moves upward and rotates counterclockwise to support the elderly person to change from a sitting position to a standing position, thereby facilitating the elderly person to squat and stand when using the toilet, thereby improving the comfort and safety of the elderly person when using the toilet. Moreover, by controlling the motor 301 to drive the first screw 30 to rotate and drive the guide seat 20 to move downward or upward, the seat cushion 201 can support the elderly to change from standing to sitting and then to squatting or from squatting to sitting and then to standing. The operation is simple and convenient, and the comfort of squatting and standing of the elderly is further improved. At the same time, when the guide seat 20 is lower than the height of the seat, the height of the seat cushion 201 in the horizontal state can be adjusted by controlling the motor 301 to drive the first screw 30 to rotate and drive the guide seat 20 to move downward or upward, so that the height of the squatting toilet can be adjusted according to the needs, which is convenient for different elderly people to use and improves the practicality of the device.
