DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0018] like Figures 1 to 5As shown, the embodiment of the utility model provides a bathing hanging basket device based on a pneumatic motor, including a hanging basket rotating shaft 1, a hanging basket 2, and a hanging basket bracket 3, wherein the hanging basket rotating shaft 1 is arranged on the hanging basket bracket 3, and the hanging basket 2 is arranged on the hanging basket rotating shaft 1 through a pull rope, and further includes: a fixed arm 4, a supporting arm 5, a two-way valve 6, a first valve 7, a second valve 8, and a pneumatic motor 9; the two-way valve 6 is provided with an air inlet 61, a forward rotation port 62 and a reverse rotation port 63, the air inlet 61 is connected to the underground pressure air pipeline, and the forward rotation port 62 and the reverse rotation port 63 are respectively The two air inlets of the pneumatic motor 9 are connected through the first valve 7 and the second valve 8; the pneumatic motor 9 is used to drive the hanging basket shaft 1 to rotate and drive the hanging basket 2 to move up and down; the fixed arm 4 is horizontally arranged and fixedly connected to the hanging basket bracket 3, and the first valve 7 and the second valve 8 are respectively arranged at the lower end and the upper end of the fixed arm 4; one end of the support arm 5 is rotatably arranged on the hanging basket shaft 1, and the support arm 5 is provided with a first limiting portion 51 and a second limiting portion 52 which cooperate with the first valve 7 and the second valve 8 respectively.

[0019] Specifically, in this embodiment, Figure 2 As shown, the two-way valve 6 includes a valve body 64 and a valve core 65. The air inlet 61, the forward rotation port 62 and the reverse rotation port 63 are arranged on the valve body 64, and the valve core 65 is provided with a hole 66. One end of the hole 66 is always connected with the air inlet 61, and the other end is connected with the forward rotation port 62 or the reverse rotation port 63. By rotating the valve core 65, the hole 66 can be rotated to realize the connection between the air inlet 61 and the forward rotation port 62, or the connection between the air inlet 61 and the forward rotation port 62, or the connection between the forward rotation port and the reverse rotation port. Specifically, when the valve core 65 is rotated to 0°, the two-way valve 6 is closed, when it is rotated to 90°, the hole 66 connects the reverse rotation port 63 with the air inlet 61, and when it is rotated to -90°, the hole 66 connects the forward rotation port 62 with the air inlet 61.

[0020] Furthermore, if Figure 2 As shown, in this embodiment, a lock body 67 is also provided on the valve body 64, and the lock core of the lock body 67 is fixedly connected to the valve core 65, so that the valve core 65 can be driven to rotate by turning the key, thereby connecting the channel 66 with the forward rotation port 62 or the reverse rotation port 63.

[0021] Furthermore, if Figure 1 As shown, a bathing basket device based on a pneumatic motor in this embodiment further includes a return spring 41 arranged between the fixed arm 4 and the supporting arm 5 .

[0022] Furthermore, if Figure 3As shown, in this embodiment, the housing of the pneumatic motor 9 is fixed on the support arm 5, and the rotating shaft is in driving connection with the hanging basket rotating shaft 1. In addition, four through holes are provided on the support arm 5, one of which is sleeved on the hanging basket rotating shaft 1 or the pneumatic motor 9 rotating shaft, and the other three through holes are sleeved on the fixing bolts of the pneumatic motor 9, so that the support arm 5 and the pneumatic motor 9 can rotate around the hanging basket rotating shaft 1 to a certain extent, because the first limiting portion 51 and the second limiting portion 52 limit the rotation range of the support arm 5.

[0023] Specifically, in this embodiment, the pneumatic motor 9 may be a pneumatic motor of model 5VD60, and the first valve 7 and the second valve 8 may be valves of model MOV-02.

[0024] The working process and working principle of the utility model are as follows: the first valve 7 is a valve that rises to the position, and the second valve 8 is a valve that descends to the position. When the position of the hanging basket 2 is between the ground and the support arm 5, the support arm 5 maintains a horizontal state, and the first limit part 51 and the second limit part 52 thereon do not contact the corresponding valve. When the key is in the middle zero position, the two-way valve 6 is closed, and the pneumatic motor 9 does not work. When the key is transferred to the left to the -90° position, the air inlet 61 and the forward rotation port 62 are connected, and the first valve 7 is not pressed by the first limit part 51, then the first valve 7 is opened, and the compressed air enters the forward rotation air inlet of the pneumatic motor, and the pneumatic motor 9 is connected in the forward direction, driving the hanging basket 2 to move upward. After reaching the designated rising position, the hanging basket pushes the support arm 5 upward to make it rotate upward away from the end of the hanging basket rotating shaft 1, then the first limit part 51 presses the first valve 7, so that the first valve 7 is closed, the pneumatic motor 9 stops working, and the hanging basket stops moving. When the key is turned right to the 90° position, the air inlet 61 and the reversing port 63 are connected. At this time, the second valve 8 is not pressed by the second limiting portion 52, so the second valve 8 is opened, and the compressed air enters the reversing air inlet of the pneumatic motor. The pneumatic motor 9 is reversely connected to drive the hanging basket 2 to move downward, and the support arm 5 rotates to the horizontal under the action of the reset spring 41, but the second valve 8 remains open; when the hanging basket 2 reaches the ground, the force on the hanging basket shaft 1 suddenly decreases and rotates in the opposite direction at a small angle. Since the shaft of the pneumatic motor 9 is fixedly connected to it, the housing and shaft of the pneumatic motor 9 also rotate slightly downward by a certain amplitude at this time, so that the support arm 5 fixed to the pneumatic motor 9 rotates slightly, and the end thereof away from the hanging basket shaft 1 drops, and the second limiting portion 52 presses the second valve 8 to close the second valve 8, the pneumatic motor 9 stops working, and the hanging basket 2 stops moving.

[0025] In summary, the utility model provides a bathing basket device based on a pneumatic motor, which can realize the lifting and lowering of the basket through the pneumatic motor and two valves, and can avoid fire accidents caused by circuit aging of the electric basket.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
