Description

Pneumatic locking means is felt with thing allies oneself with cloud to accompany nursing chair

Technical Field

Relate to the technical field of accompanying chairs, in particular to a pneumatic locking device for an object connection cloud sense of an accompanying chair.

Background

In order to solve the contradiction between doctor-patient demand and medical resource shortage, the intelligent sharing medical construction is continuously promoted. The medical accompanying chair is a multifunctional chair provided for patient nursing staff by a hospital and is widely used in each ward. The accompanying chair mainly has two working states: the first is that the chair is folded in the daytime and used as a common chair, so that the ward space can be saved, and medical staff can conveniently go in and out of the chair; the second is that the bed is used as a bed for accompanying and nursing when the bed is pulled open at night, so that accompanying and nursing staff can sleep and rest at night, and the bed occupies a larger ward space. Therefore, the accompanying chair needs to change its own state continuously according to the management time of the hospital. At present, in the actual operation process, the two state conversion management is troublesome, and medical personnel are required to lock and unlock the lock specially and manually, so that part of hospitals directly give up management.

The problems that locking is inconvenient, and unified opening and locking cannot be performed at regular time exist in the current accompanying chair management, so that patients and accompanying personnel can be folded or pulled away at will, and difficulty is brought to hospital ward management. Under the direction in wisdom ward, strengthen the intelligent management of medical chair of accompanying and attending to imperatively.

In order to solve the problems in the prior art, the invention provides a pneumatic locking device for an accompanying chair with a cloud feeling, and solves the problems that the accompanying chair is inconvenient to lock and cannot be opened and locked regularly in a unified mode in the prior art. .

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

With reference to fig. 1-2, an internet of things cloud-sensing pneumatic locking device for an accompanying chair comprises a pressure movable cylinder 1, a one-way solenoid valve 2, a two-way solenoid valve 3, an internet of things control box 4 and an internal circulation pipeline 10, wherein the pressure movable cylinder 1 comprises a pressure pipe 5, a closed piston 6, a piston rod 7, a medium 9, an external port 8, a first connecting piece 11.1 and a second connecting piece 11.2, one end of the pressure pipe 5 is in a closed state, the other end of the pressure pipe is in an open space, the external port 8 is respectively arranged at two ends of the pressure movable cylinder 5, the external port 8 is connected with the internal circulation pipeline 10, the closed piston 6 is arranged in the pressure movable cylinder 5, one end of the closed piston 6 is connected with the piston rod 7, the other end of the closed piston 6 is not arranged at the open space side of the pressure movable cylinder 5 and is in a closed connection with a port, so as to prevent the, the piston rod 7 can move to drive the sealing piston 6 to slide, the medium 9 is generally oil, liquid water or gas, the first connecting piece 11.1 is arranged at the closed end of the pressure movable cylinder 5, and the second connecting piece 11.2 is arranged at the top end of the piston rod 7 and used for external fixed connection and telescopic control of the gas spring 1. The two sides of the internal circulation pipeline 10 are respectively provided with the one-way electromagnetic valve 2 and the two-way electromagnetic valve 3, the one-way electromagnetic valve controls whether the medium 9 of the one-way electromagnetic valve 2 can flow in a one-way mode from left to right, and the two-way electromagnetic valve 3 controls whether the medium 9 allows two-way flow. Thing allies oneself with control box 4 and receives cloud server control, with one-way solenoid valve 2 with two-way solenoid valve 3 links, including control chip 12, communication module 13 and power supply unit 14, control chip 12 does accompany the chair thing and allies oneself with the control center of the pneumatic locking means of cloud, is responsible for the processing and the instruction output and the control of business logic one-way solenoid valve 2 with opening and closing of two-way solenoid valve 3 switch, communication module 13 for receive the instruction that comes from outside sending, including but not limited to communication methods such as bluetooth, NB-IOT, roller, power supply unit 14 is used for thing allies oneself with control box 4 one-way solenoid valve 2 with two-way solenoid valve 3 supplies power.

The pressure movable cylinder 5 is fixed on a back plate 18 of the accompanying chair 15 through the second connecting piece 11.2, and the piston rod 7 is fixed on a backup plate 17 of the accompanying chair 15 through the first connecting piece 11.1. When the accompanying chair 15 is pulled open, the piston rod 7 is stretched outwards along with the backup plate 17 until the accompanying chair 15 is in a flat state; when the accompanying chair 15 is folded, the piston rod 7 is retracted inwards along with the backup plate 17 until the accompanying chair 15 is in a chair state.

The thing allies oneself with control box 4 and cloud ware direct link to each other, and cloud ware can be unified to the thing allies oneself with control box 4 sends accompanying chair 15 and opens or close the instruction. When the internet of things control box 4 senses an opening instruction of an accompanying chair 15 sent by a cloud server, the control chip 12 opens the switch of the two-way electromagnetic valve 3, closes the switch of the one-way electromagnetic valve 2, and at the moment, the medium 9 can freely flow in the pressure movable cylinder 5 and the internal circulation pipeline 10, so that the closed piston 6 can freely move in the pressure pipe 5, and the purpose that the accompanying chair 15 can be freely pulled open or folded is achieved; when the Internet of things control box 4 senses an accompanying chair 15 closing instruction sent by a cloud server, the switch of the two-way electromagnetic valve 3 is closed through the control chip 12, the switch of the one-way electromagnetic valve 2 is opened, at the moment, the medium 9 flows from left to right through the internal circulation pipeline 10, the closed piston 6 is promoted to be subjected to pressure difference and can only slide in one direction towards the closed end of the pressure movable cylinder 5, and cannot be pulled out, and therefore the purpose that the accompanying chair 15 is only allowed to retract in one direction and cannot be pulled out for use is achieved.

The working principle of the invention is as follows: the control chip 12 controls the folding and unfolding states of the accompanying chair 15 by controlling the opening and closing of the one-way electromagnetic valve 2 and the two-way electromagnetic valve 3.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
