Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 The utility model provides a technical solution: a health care chair that swings forward and backward, comprising: a base frame 1; a spring 2 is fixedly connected to the top of the base frame 1, a seat 3 is fixed to one end of the spring 2, two slide rails 4 are respectively fixed to the bottom of the seat 3, the two slide rails 4 are vertically downwardly provided with slideways, a slider 5 is slidably connected in the slideway of the slide rail 4, two electric cylinders 6 are fixed to the top of the base frame 1, and a connection mechanism is respectively provided between the telescopic shafts of the two electric cylinders 6 and the two sliders 5, which can be disassembled to allow the seat 3 to swing without electricity;

[0025] The spring 2 is used to assist the seat 3 to swing. The two slide rails 4 and the two electric cylinders 6 are respectively located in front of and behind the seat 3. The telescopic shaft of the electric cylinder 6 is connected to the slider 5 of the corresponding slide rail 4 through a connecting mechanism. The electric cylinder 6 pushes and pulls the connecting mechanism and the slider 5 of the slide rail 4 to allow the seat 3 to swing back and forth. In an environment without electricity, the connecting mechanism can be removed so that the seat 3 can swing only through the spring 2.

[0026] Preferably, the connection mechanism includes a first threaded joint 7, a second threaded joint 8 and a connecting rod 9, the mounting end of the first threaded joint 7 is fixed to one end of the telescopic shaft of the electric cylinder 6, and the mounting end of the second threaded joint 8 is hinged to one end of the slider 5;

[0027] The telescopic shaft of the electric cylinder 6 is fixedly connected to the first threaded joint 7 of the connecting mechanism to control the up and down movement of the first threaded joint 7, and one end of the second threaded joint 8 is hinged to the slider 5 for rotation, and cooperates with the slider 5 to move and push the seat 3 to swing.

[0028] Preferably, the thread directions of the threaded connection ends of the first threaded joint 7 and the second threaded joint 8 are consistent, and a connecting rod 9 is threadedly connected between the threaded connection ends of the first threaded joint 7 and the second threaded joint 8;

[0029] The thread directions of the connecting ends of the first threaded joint 7 and the second threaded joint 8 are consistent, so that the first threaded joint 7 and the second threaded joint 8 can be connected simultaneously when the connecting rod 9 rotates.

[0030] Preferably, the thread groove of the connecting rod 9 connected to the first threaded joint 7 is twice as long as the thread groove of the connecting rod 9 connected to the second threaded joint 8;

[0031] The thread groove of the connecting rod 9 connected to the first threaded joint 7 can be completely swallowed by the connecting end of the first threaded joint 7, which facilitates the separation of the other end of the connecting rod 9 from the second threaded joint 8 and is used to assist the disassembly and assembly of the connecting rod 9.

[0032] Preferably, two symmetrical limiting plates 12 are fixed on the top of the base frame 1, and the two limiting plates 12 are respectively located on both sides of the spring 2;

[0033] The limiting plates 12 on both sides of the spring 2 are used to help limit the left and right swinging of the spring 2 and the seat 3.

[0034] Preferably, two symmetrical auxiliary plates 10 are fixed to the bottom of the seat 3, and the two auxiliary plates 10 are respectively attached to the outer wall of the limiting plate 12 and are provided with path holes 11;

[0035] The two auxiliary plates 10 of the seat 3 are respectively located on the outer walls of the two limiting plates 12, and cooperate with each other to prevent the seat 3 from being easily deviated and swinging forward and backward.

[0036] Preferably, the outer walls of the two limiting plates 12 are fixed with a stopper 13, and the two stoppers 13 are respectively arranged in the two path holes 11;

[0037] The stopper 13 of the limiting plate 12 is placed in the curved path hole 11 of the auxiliary plate 10. When the stopper 13 contacts one end of the curved path hole 11, it means that the swing amplitude is large, and it is a reminder to adjust the amplitude in time to avoid tipping over.

[0038] A specific application of this embodiment is: the health care personnel sit on the seat 3, and then can push and pull alternately through the telescopic shafts of the two electric cylinders 6, and through the connecting mechanism to cooperate with the slider 5 of the two slide rails 4, the seat 3 can be swung back and forth, and the accompanying personnel do not need to manually push and pull the seat 3. When there is no electricity in the environment, the connecting rod 9 can be rotated first, and the threaded groove used to connect the first threaded joint 7 is completely swallowed into the first threaded joint 7, and the threaded groove at one end of the second threaded joint 8 will be disengaged from the second threaded joint 8. At this time, the slider 5 and the second threaded joint 8 can be removed, and the connecting rod 9 can be rotated to disengage it from the first threaded joint 7. At this time, when there is no electricity in the environment, the seat 3 can also be pushed and pulled by manpower to swing.
