The following further describes embodiments of the present invention with reference to the drawings. It is to be noted that the description of the embodiments is provided to aid understanding of the present invention, and is not intended to limit the present invention. Furthermore, the technical features and technical means mentioned in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1, 2, 3, 4 and 9, the defecation hole sealing mechanism for the defecation type nursing bed comprises a swing arm 8 which is hinged on two cross beams, namely a cross beam 6 and a cross beam 7, below a defecation hole 26 through a swing arm hinge shaft 9 and is provided with a hole sealing defecation hole plug 55, the swing arm 8 is generally a rectangular frame, a defecation hole plug supporting plate 56 or a base plate is arranged on the swing arm 8, a defecation hole plug is arranged on the defecation hole plug supporting plate 56, and the defecation hole plug 55 is also called a defecation plug. A driving locking device installed on the frame 1 for driving the swing arm 8 to the hole sealing position and locking or driving the swing arm 8 away from the hole sealing position: one end of the swing arm 8 is hinged on the bedstead 1 through a swing arm hinge shaft 9 and fixed with one end of a push-pull block 10, the other end of the push-pull block 10 is hinged with one end of a connecting rod 11, the connecting rod 11 is driven by a driving rod 12 and a driving block 13 in a manual driving device which is described below so as to drive the swing arm 8 through the push-pull block 10 to enable a defecation hole plug 55 to seal or fill the defecation hole 26 or keep away from the defecation hole 26, and two ends of the swing arm hinge shaft 9 are respectively hinged on two cross beams, namely a cross beam 6 and a cross beam 7, on the bedstead 1. The other end of the connecting rod 11 is hinged with a connecting rod shaft hole 15 on the driving block 13 through a shaft, and a U-shaped groove 16 for accommodating the end-segment connecting rod is arranged in the transverse edge of the driving block 13 provided with the connecting rod shaft hole 15. When the driving rod 12 drives the driving block to horizontally rotate 180 degrees along the self hinge shaft to a dead point such as a left dead point, the connecting rod 11 drives the swing arm 8 and the defecation hole plug 55 to close the defecation hole 26; when the driving rod 12 drives the driving block to horizontally rotate 180 degrees along its own hinge shaft to another dead point such as a right dead point, the driving rod 12 drives the driving block 13 to make the hole plug 55 far away from the defecation hole 26. The own hinge shaft here is hinged in the uppermost hinge hole in fig. 2, but of course, when the drive rod 12 and the drive block 13 are at the left dead center in horizontal use, the hinge hole is at the innermost side.
The driving and locking device is installed on the bedstead and used for driving the swing arm to the hole sealing position and locking or driving the swing arm to be far away from the hole sealing position. The driving locking device which is arranged on the bed frame and used for driving the swing arm to the hole sealing position and locking or driving the swing arm to be far away from the hole sealing position has a plurality of other specific structures in the prior art, for example, the self-service bed with application publication No. CN102218001A adopts an electric driving shaft to rotate so that the swing arm provided with the hole plug is swung to an upper limit or falls to a lower limit, and the swing arm is positioned and lifted only by a rotating shaft at the other end far away from the hole plug. In a nursing bed with a defecation facility sold in the market, a driving locking device which is arranged on a bed frame and used for driving a swing arm to a hole sealing position and locking or driving the swing arm to be far away from the hole sealing position has other specific structures, but the driving locking device is positioned and lifted only by a rotating shaft at the other end far away from a defecation hole plug. That is, no matter what the specific structure of the driving locking device installed on the bed frame for driving the swing arm to the hole sealing position and locking or driving the swing arm to be far away from the hole sealing position, as long as the free end of the swing arm is suspended only by the locking hinge shaft, the locking and unlocking device of the invention is added to lock or unlock the free end of the swing arm far away from the other end of the swing arm hinge shaft on the bed frame, so as to overcome the defects that the free end of the swing arm and the hole plug cannot bear the weight of the patient and are sunken downwards and make the patient feel uncomfortable when the patient sleeps, especially when the patient needs to sit up for defecation or other situations, and the invention falls into the protection scope of the invention.
The free end locking and unlocking device of the swing arm of the defecation hole sealing mechanism can also be called as a locking device and an unlocking device of the free end of the swing arm when being unfolded. It will be understood that the locking and unlocking means are actually one device, but operate in the reverse direction, locking in the forward direction and unlocking in the reverse direction, as will be described in the following five embodiments.
As shown in fig. 4 and 5, a first specific structure of the locking and releasing device is as follows: a hole 22 for a movable shaft 25 to move axially is arranged on the cross beam 6 on one side corresponding to the position of the free end 18 of the swing arm at the upper limit position, a shaft sleeve 23 can be arranged between the hole 22 and the movable shaft 25, and the movable shaft 25 slides axially in the shaft sleeve 23. The movable shaft 25 can also be axially movable directly in the hole 22, but it is preferred to provide a sleeve 23, in which sleeve 23 the movable shaft 25 axially slides. The other end of the movable shaft 25 far from the free end 18 of the swing arm is connected with one end of the crank arm 19, a hole at the end of the crank arm 19 is movably sleeved at the end of the movable shaft 25, the outer end of the movable shaft 25 is provided with a limiting structure 24, and the inner end of the crank arm 19 at the end is also provided with the limiting structure 24. The middle of the crank arm 19 is hinged on the cross beam 6 through a crank arm hinge shaft 21, the other end of the crank arm 19 is provided with a clutch groove 20 which is embedded in or separated from the driving shaft 17 on the driving block 13 of the driving locking device, so that the movable shaft 25 is driven by the crank arm 19 to extend into the bottom of the free end 18 of the swing arm so as to lock the free end 18 of the swing arm or retract axially so as to be separated from the free end 18 of the swing arm.
As shown in fig. 1, 4, 5, 6, 7, 8 and 9, when the driving rod 12 drives the driving block 13 to rotate horizontally 180 ° along its hinge axis to a dead point, such as the left dead point in the figure, the connecting rod 11 drives the swing arm 8 and the hole plug 55 to close the hole 26; meanwhile, the driving shaft 17 on the driving block 13 is embedded with the clutch groove 20 at the end of the crank arm 19 to drive the crank arm 19 to swing along the crank arm hinge shaft 21, the connecting end at the other end of the crank arm 19 pushes the movable shaft 25 to gradually extend to the right, and when the free end 18 of the swing arm reaches the top dead center position, the movable shaft 25 axially extends into the bottom of the free end 18 of the swing arm to lock the free end of the swing arm; on the contrary, when the driving rod 12 drives the driving block 13 to rotate 180 ° horizontally along its own hinge shaft to another dead point such as the right dead point, the driving shaft 17 on the driving block 13 drives the crank arm 19 to rotate in the opposite direction, the movable shaft retracts to disengage from the free end 18 of the swing arm, and the driving shaft 17 disengages from the clutch slot 20, and at the same time, the driving rod 12 drives the driving block 13 to make the hole plug 55 far away from the defecation hole 26 through the connecting rod 11 and the swing arm 8.
The first specific structure can be further modified as follows: when the free end of the swing arm is positioned at the upper limit position, a hole for the movable shaft to move axially is also arranged on the beam at the other side, a shaft sleeve can also be arranged between the hole and the movable shaft, and the movable shaft axially slides in the shaft sleeve. The other end of the movable shaft far away from the free end of the swing arm is connected with one end of a crank arm, the middle of the crank arm is hinged on the cross beam through a crank arm hinge shaft, and the other end of the crank arm is provided with a separation groove which is embedded or separated with a driving shaft on a driving block, so that the movable shaft is driven by the crank arm to extend into the bottom of the free end of the swing arm to lock the free end of the swing arm or retract axially to separate from the free end of the swing arm. That is, the other symmetrical side is also provided with a locking and releasing device with basically the same structure, four points are arranged on one side, and the technical effect that the defecation hole plug at the defecation hole cannot be sunken downwards at any time is better. The working principle of the structure is the same as that of the first specific structure. The main difference is that the driving rod and the driving block are arranged independently and are not linked with a driving locking device which is used for driving the swing arm to the hole sealing position and locking or driving the swing arm to be far away from the hole sealing position, namely the driving locking device is not included.
As shown in fig. 10 and 11, a second specific structure of the locking and releasing device is as follows: a locking block hinge shaft 27 is arranged on the cross beam 6 on one side corresponding to the swing arm free end 18 when the swing arm free end 18 is located at the upper limit position, the middle of a locking block 28 for supporting the bottom of the swing arm free end 18 is hinged on the locking block hinge shaft 27, a cut-in inclined plane 29 is arranged at one end, close to the swing arm free end 18, of the locking block 28, the other end, far away from the swing arm free end 18, of the locking block 28 is hinged with one end of a locking block connecting rod 30 through the hinge shaft, the other end of the locking block connecting rod 30 is hinged with a locking block driving shaft 53 on the driving block, and the locking block 28 is driven by the locking block connecting rod 30 to rotate and extend into the bottom of the swing arm free end 18 to lock the swing arm free end 18 or rotate back to be separated from the swing arm free end 18. In the left dead centre position of the drive block shown in figure 10, the connecting rod drive shaft 54 is hinged in the outermost bore of the drive block, and the locking block drive shaft 53 is hinged in the middle bore of the drive block, the innermost bore being the hinge bore of the drive block's own hinge shaft.
As shown in fig. 10, 11 and 9, when the driving rod drives the driving block to rotate horizontally by 180 ° along its own hinge axis to a dead point, such as a left dead point, the connecting rod 11 drives the swing arm 8 and the hole plug 55 to close the defecation hole 26; at the same time, the lock driving shaft 53 drives the lock link 30 and thus the lock 28 to rotate along the hinge shaft 27, and the cut-in slope 29 gradually extends so that the top of the lock 28 abuts against the bottom of the swing arm free end 18 to lock the swing arm free end 18; on the contrary, when the driving rod drives the driving block to rotate 180 ° horizontally along its own hinge shaft to another dead point such as the right dead point, the locking block driving shaft 53 drives the locking block connecting rod 30 to further drive the locking block 28 to rotate reversely along the locking block hinge shaft 27, the cut-in inclined plane 29 gradually withdraws until the locking block 28 is separated from the swing arm free end 18, and at the same time, the driving rod drives the driving block to drive the swing arm 8 to swing through the connecting rod 11 to make the excrement hole plug 55 far away from the excrement discharge hole 26.
