In order to realize the purpose, the following technical scheme is adopted: an auxiliary traction type toilet seat overturning driving device comprises a fixed clamping plate fixed below a rotary shaft seat of a toilet seat, wherein a shell is arranged on the side surface of the fixed clamping plate, a driving cavity is arranged in the shell, and a vertical abdicating slotted hole is formed in the front side surface of the shell; a fixed seat is arranged in the driving cavity, and the lower end of a driving plate sleeved in the abdicating slot is hinged on the fixed seat through a pin shaft; meanwhile, a front pin shaft and a rear pin shaft are sequentially arranged at the bottom of the inner end of the driving cavity and are respectively hinged with a pedal rod and a half sleeve rod, and the half sleeve rod is arc-shaped and can be sleeved on the outer side of the pedal rod in a matching manner; the rear end of the half loop bar is provided with a swing end exceeding a rear pin shaft, a main tension spring is connected between the swing end and a front and rear telescopic adjusting mechanism arranged at the rear side of the driving cavity, a rear auxiliary tension spring is connected between the swing end and the driving plate, and a front auxiliary tension spring is connected between the pedal rod and the driving plate; the front end of the driving plate is provided with a bending head which is fixed below the toilet seat cushion.

The front and back telescopic adjusting mechanism is characterized in that a through hole is formed below the rear wall of the driving cavity, a screw rod is sleeved in the through hole, an adjusting nut is installed at the outer end of the screw rod, which is located at the through hole, and the inner end of the screw rod, which is located at the through hole, is connected with the main tension spring.

Has the advantages that: when the tension adjusting device is used, the tension of the main tension spring can be directly adjusted through the front and rear telescopic adjusting mechanisms, and the rear auxiliary tension spring and the front auxiliary tension spring are indirectly adjusted. The downward stepping of the foot stepping rod can break the balance of the vertical cushion, so that the cushion is inclined and is leveled under the action of self weight. The gravity of the driving plate and the cushion can be balanced through the front and rear telescopic adjusting mechanisms, and the front and rear telescopic adjusting mechanisms are adjusted to be slightly lower than the gravity of the cushion. The foot is used for slightly poking the lower part of the pedal rod upwards, and the cushion can be lifted. Therefore, the structure of the invention also has the buffer function of making the cushion fall.

Due to the matching effect of the main tension spring and the two auxiliary tension springs, after the front and rear telescopic adjusting mechanisms are reasonably adjusted, the cushion can have larger swing amplitude through small-amplitude driving of the foot treading rod. And the pedal rod can automatically return to the middle position each time so as to be convenient for continuous operation.

The invention can control different tension of the tension spring through the front and back telescopic adjusting mechanism, thereby being suitable for overturning toilet cushions of various types. No matter the gravity of the toilet seat cushion is larger or smaller, the tension spring can be adjusted to be in the best position through the front and back telescopic adjusting mechanism.

Detailed Description

Example (b): an auxiliary traction type toilet seat overturning driving device is shown in fig. 1, and the device fixes essential parts such as a clamping plate 1, a shell 2, a driving plate 7, a foot stepping rod 8 and the like. As shown in fig. 3, the fixing clamping plate 1 is fixed below the rotary shaft seat of the toilet seat, so that the whole device is stably installed and normally operated.

Referring to fig. 2, a casing 2 is arranged on the side surface of the fixed clamping plate 1, and a driving cavity 3 is arranged in the casing 2. The front side of the shell 2 is provided with a vertical abdicating slotted hole 4. A fixed seat 5 is arranged in the driving cavity 3, and the lower end of a driving plate 7 sleeved in the abdicating slotted hole 4 is hinged on the fixed seat 5 through a middle pin shaft.

As shown in fig. 4, the front end of the driving plate 7 is provided with a bent head fixed below the toilet seat.

The bottom of the inner end of the driving cavity 3 is sequentially provided with a front pin shaft 11 and a rear pin shaft 12, the front pin shaft 11 and the rear pin shaft 12 are respectively hinged with a pedal rod 8 and a half sleeve rod 9, and the half sleeve rod 9 is arc-shaped and can be sleeved on the outer side of the pedal rod 8 in a matching mode. Therefore, when the foot pedal 8 is stepped by feet, the half loop bars 9 can be driven to move together, the rear ends of the half loop bars 9 are provided with swing ends 10 exceeding the rear pin 12, main tension springs 13 are connected between the swing ends 10 and the front and rear telescopic adjusting mechanisms arranged on the rear side of the driving cavity 3, and rear auxiliary tension springs 14 are connected between the swing ends 10 and the driving plate 7. A front auxiliary tension spring 15 is connected between the foot pedal rod 8 and the drive plate 7, the foot pedal rod 8 pulls the drive plate 7 to move forwards through the front auxiliary tension spring 15, and meanwhile, the half loop bar 9 swings to drive the swing end 10 to push forwards, so that the rear auxiliary tension spring 14 loses tension. The driving plate 7 and the cushion which are processed in the vertical state can be turned over and laid flat instantly through the motion relation of matching of the traction and the back pushing. The cushion is at the process of laying level, can last downstream under the cushion dead weight effect, no longer need the foot to step on the drive. However, at this time, the main tension spring 13 receives a larger and larger tension, so that the moving speed of the seat cushion is restricted, and the cushion has a buffering effect. Therefore, the overturning driving of the cushion can be realized only by driving the foot treading rod 8 in a small amplitude, the labor is saved, the operation is convenient, and the cushion can have a large swinging amplitude through a small swinging amplitude.

A front and rear telescopic adjusting mechanism is arranged at the rear side of the driving cavity 3, as can be seen from fig. 2, the front and rear telescopic adjusting mechanism is characterized in that a through hole is arranged below the rear wall of the driving cavity 3, a screw rod is sleeved in the through hole, an adjusting nut 18 is arranged at the outer end of the screw rod, which is positioned in the through hole, and the inner end of the screw rod, which is positioned in the through hole, is connected with the main tension spring 13. Different tension forces of the tension springs can be controlled through the front and rear telescopic adjusting mechanisms, so that the toilet seat can be suitable for overturning toilet seats of various models. No matter the gravity of the toilet seat cushion is larger or smaller, the tension spring can be adjusted to be in the best position through the front and back telescopic adjusting mechanism.

In the cushion in a flat state, the main tension spring 13 and the rear auxiliary tension spring 14 are both under the traction action, so the swinging end 10 of the half loop bar 9 is positioned at the middle position of the main tension spring 13 and the rear auxiliary tension spring 14, and as can be seen, the included angle between the position where the pedal rod 8 and the half loop bar 9 stay after swinging each time and the original position is not too large.

According to the moment relation, the cushion has the biggest pulling force to main extension spring 13 and back auxiliary extension spring 14 when being located horizontal position, and is difficult to lift the cushion this moment. The tension of the main tension spring 13 and the rear auxiliary tension spring 14 is slightly smaller than the gravity of the cushion by adjusting the front and rear telescopic adjusting mechanisms. The balance can be broken by only slightly lifting the foot pedal 8 upwards with the foot. The main tension spring 13 and the rear auxiliary tension spring 14 work together to enable the driving plate 7 to move upwards together with the cushion, and finally the cushion is in a vertical state.
