Embodiment Construction

[0009] The mechanism uses tap water as power, and is designed as a special hydraulic transmission mechanism, which utilizes the area difference between the cavity of the piston rod 707 and the piston cavity to achieve rapid retraction of the piston rod even if the flow rate in the cavity of the piston rod is small. To achieve the purpose of quickly opening the drop door. The process is: the hydraulic water cylinder 709 is transformed from a listed pneumatic cylinder, the diameter of the piston rod 707 is close to the inner diameter of the cylinder barrel, the bottom of the piston chamber of the hydraulic water cylinder 709 is made with a large-diameter pipe thread, connected to the tee 703, and when the piston rod chamber enters the small Flow tap water (use the modified small-diameter gas electromagnetic reversing valve for water supply, which has anti-corrosion ability.), the piston chamber is additionally connected with a large-diameter electromagnetic water valve 704 for dr...

Abstract

A hydraulic water cylinder rapid action mechanism for an automatic assistance bed urinal serves patients needing to defecate on a bed with the prone position, when patients lying in bed randomly shitor pee, a monitoring mechanism can be triggered in time to acquire signals, a signal drive mechanism opens an excrement falling door rapidly, and the patients enter the defecating manner with the prone position. In order to reduce pollution of urinating and defecating to bedding to the greatest extent, after the mechanism receives the instruction of opening the excrement falling door, the door needs to be fast opened. If conventional hydraulic design is adopted, action of the mechanism is too slow, and the rapid requirement cannot be met. A hydraulic water cylinder in the mechanism is modifiedfrom an air cylinder on the market, the diameter of a piston rod of the hydraulic water cylinder is close to the inner diameter of a cylinder barrel, and therefore when a large-diameter electromagnetic water valve is additionally connected to a water cylinder lower cavity, and the piston rod of the hydraulic water cylinder can rapidly retract through small rod cavity flow. Therefore, the excrement falling door can be opened rapidly. The air cylinder is modified into the tap water cylinder, a small-drift-diameter outlet of a piston cavity is changed into a newly-added large-drift-diameter outlet, and the large-caliber electromagnetic water valve and a water storage tank are additionally mounted.

Description

technical field [0001] The invention belongs to a hydraulic water cylinder mechanism for opening a toilet drop door for an automatic defecation-assist horizontal toilet, in particular to a hydraulic water cylinder with the function of rapidly retracting a piston rod and a mechanism for supporting parts therewith. Background technique [0002] Among the existing hospital beds with falling doors, there is one with the fastest door opening speed, about 5 seconds. The opening time of other similar beds is two to three times that. Of course, under the premise of getting the patient's cooperation, the patient can endure the defecation door after expressing his desire to defecate, and a faster speed is not necessary. If it is faster, it must be supported by a sudden increase in motor power. But if there is no need to express and pull or can not carry out the control of a little longer, then the speed of opening the toilet door must be greatly accelerated. In the existing hospita...
