[0034] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0035] See also Figures 1 to 5 According to one embodiment of the present invention, there is provided a barrier-free floor drain for a shower room, comprising a floor drain trough body 1 provided with a drain port 10, a floor drain cover 11 provided on the floor drain trough body, a water baffle 2 provided in the floor drain trough body 1, and a lifting mechanism for lifting the water baffle 2, wherein a movable space for the water baffle 2 to extend is provided between the side wall of the floor drain trough body 1 and the side wall of the floor drain cover 11;

[0036] Among them, the lifting plate mechanism includes a mounting seat 6 arranged on both sides of the floor drain trough, a rotating shaft 3 installed in the mounting seat, a lifting arm 4 for lifting the water baffle 2, a pushing arm 5 for side pressure contact with the door body and a pry bar 7 hinged in the mounting seat 6, the lifting arm 4 and the pushing arm 5 are arranged on the rotating shaft 3, and the water baffle 2 is located above the lifting arm 4, so that when the pushing arm 5 is pushed, the lifting arm 4 follows the rotation of the rotating shaft 3 to lift the water baffle 2.

[0037] See also Figure 3 The surface of the mounting seat 6 is provided with a through hole 61 for pressing down one end of the pry bar 7, one end of the pry bar 7 is arranged corresponding to the through hole 61, and the other end of the pry bar 7 is located below the floor drain cover 11. The middle part of the pry bar 7 is provided with a pry bar shaft 71 for connecting with the mounting seat 6, and the inner top surface of the mounting seat 6 is provided with a pry bar shaft hole for installing the pry bar shaft.

[0038] Specifically, see Figure 2In order to improve the support strength of the floor drain cover 11 to withstand the pressure of human body or wheelchair, a support block 12 for supporting the floor drain cover 11 is provided in the floor drain trough 1. Moreover, the support block 12 is provided with a drainage through hole 121 to improve the smoothness of water flow in the floor drain trough 1.

[0039] Further, see Figure 7 In order to make the floor drain trough 1 have good drainage performance even in the case of low water flow, the bottom surface of the support block 12 is provided with a hydrophobic strip 122 for water repelling, so that a water passage is formed between adjacent hydrophobic strips 122. On the other hand, when the support block 12 and the floor drain cover 11 are too close, a great adsorption force will be generated under water wetting, thereby affecting the opening of the floor drain cover 11, so the top surface of the support block 12 can also be provided with the hydrophobic strip 122 to solve the adsorption problem.

[0040] See also Figure 8 Since the existing sliding door generally includes at least two movable door bodies, at least two pushing arms 5 are provided on the rotating shaft 3 to ensure that at least one pushing arm 5 can be driven by the side pressure of the movable door body, so that the lifting arm 4 can lift the water baffle 2. The top surface of the floor drain trough 1 is provided with a movable opening 14 for the extended pushing arm, and the accumulated water in the shower room can also flow into the floor drain trough 1 from the push arm movable opening 14. Correspondingly, in order to enable each movable door body to stably press against the corresponding pushing arm 5, the top surface of the floor drain trough 1 is provided with a track block 13 for guiding the movement of the door body, and the track block 13 is provided with a directional channel 131 for the door body to pass through, and the directional channel 131 corresponds to the pushing arm 5.

[0041] Moreover, in order to reduce the impact damage of the movable door body to the pushing arm 5, the barrier-free guide rail also includes a pressing arm protection shell 16 corresponding to the pushing arm 5, one end of the pushing arm 5 is located in the pressing arm protection shell 16, and the pressing arm protection shell 16 is installed on the pry bar shaft 71 so that the pressing arm protection shell 16 swings with the pushing arm 5. Compared with the pushing arm 5, the pressing arm protection shell 16 is easier to replace and disassemble. And a relatively soft material can be selected to improve durability and cushioning.

[0042] See also Figure 6 In order to alleviate the noise caused by the rapid descent of the water baffle 2 after the door body is opened, the mounting seat 6 is provided with a buffer device 8 for buffering the downward swing of the lifting arm. The buffer device 8 is located in the floor drain trough 1, and the lifting arm 4 is provided with a contact portion 41 corresponding to the buffer device 8, so that after the pushing arm 5 loses the side pressure of the door body, the contact portion 41 will contact the buffer device 8 to slow down the downward swing speed of the lifting arm 4.

[0043] In detail, the lifting arm 4 includes a connecting section 42 connected to the rotating shaft 3 and a top contact section 43 for lifting the water retaining plate 2. The connecting section 42 and the top contact section 43 are arranged at a preset angle, so that the buffer device 8 can be arranged to contact the contact portion 41 of the connecting section 42 laterally. The buffer device 8 includes a damper and a damping rod installed on the damper, and the damping rod is arranged corresponding to the contact portion 41. The mounting seat 6 is provided with a buffer mounting hole 63 for mounting the damper, and the damper is arranged at the buffer mounting hole 63.

[0044] The bottom of the water baffle plate 2 is provided with a top contact groove 21 for inserting the top contact segment to limit the top contact segment from being separated from the bottom of the water baffle plate 2 , thereby ensuring that the top contact segment 43 and the water baffle plate 2 remain in contact.

[0045] The damper is a prior art and can be a hydraulic damper, and its structural principle is not described in detail here. The buffer device 8 can also be an elastic member, such as a spring, a rubber strip, etc., so that when the lifting arm 4 swings downward, the contact portion 41 can contact the elastic member, thereby slowing down the descending speed of the water baffle 2 and avoiding the generation of noise.

[0046] See also Figure 5 In order to improve the applicability and assembly of this embodiment, the pushing arm 5 includes a pressure arm 51 for side pressure contact with the door body and a pressure arm driving part 52 for driving the rotating shaft 3 to rotate. The pressure arm 51 and the pressure arm driving part are preferably an integrated structure.

[0047] The pressing arm driving part 52 is sleeved on the rotating shaft 3 to facilitate the disassembly, replacement and maintenance of the pushing arm 5 . In particular, the pushing arm 5 is often hit by the door body during daily use.

[0048] The rotating shaft 3 is provided with a boss 31 for the pressure arm driving part 52 to contact, and the pressure arm driving part 52 is provided with a driving block 521 corresponding to the boss 31. When the pushing arm 5 is pressed and swings, the pressure arm driving part 52 will conflict with the boss 31, thereby limiting the relative rotation between the pushing arm 5 and the rotating shaft 3, and then the pressed arm 51 drives the rotating shaft 3 to rotate through the conflict between the pressure arm driving part 52 and the boss 31.

[0049] Furthermore, in order to prevent the boss 31 and the pressure arm driving part 52 from being completely offset and unable to drive the rotating shaft 3 to rotate, the rotating shaft 3 is provided with an elastic reset member 32 for pressing the pushing arm 5 toward the boss 31 to prevent the driving block 521 from moving away from the boss 31, and the pushing arm 5 is provided on both sides of the boss 31. Preferably, the elastic reset member 32 is a torsion spring, one end of which is in contact with the mounting seat 6, and the other end is connected to or in contact with the pressure arm, so that the pushing arm is in a rotational tendency to lower the water retaining plate.

[0050] Preferably, the elastic reset member 32 is preferably a compression spring, and the mounting seat 6 is provided with a tension spring 64 for pulling down the water baffle 2, one end of the tension spring 64 is connected to the water baffle 2, and the other end is connected to the mounting seat 6, so as to maintain the downward trend of the water baffle 2. The mounting seat 6 and the water baffle 2 are both provided with a hook for installing the tension spring 64. Accordingly, the tension spring 64 can also be replaced by a connector with elastic expansion and contraction, such as a rubber band.

[0051] Furthermore, the lifting plate mechanism is provided on both sides of the floor drain trough 1 to facilitate users to switch the door body for daily sliding use according to their usage habits. Since the existing sliding door generally includes at least two movable door bodies, after opening one of the door bodies after the shower, the two sides of the water retaining plate 2 can automatically drop as a whole.

[0052] See also Fig. 9 This embodiment also includes a disengagement hook 15 for disengaging the driving block 521 from the boss 31. The mounting seat 6 is provided with a disengagement movable groove 62 for installing the disengagement hook. The disengagement hook 15 is provided with a plug-in end 150. The plug-in end 150 is inserted into the disengagement movable groove 62 to move in the disengagement movable groove 62 along the axial direction of the rotating shaft 3.

[0053] The two sides of the decoupling hook 15 are provided with decoupling surfaces 151 for propping up the two pushing arms 5, and the driving blocks 521 of the two pushing arms 5 are in conflict with the decoupling surfaces 151. The distance between the two decoupling surfaces 151 gradually increases along the rotation direction of the rotating shaft 3, which is the rotation direction of the pushing arm 5 when it is pressed by the side of the door body. In order to ensure that the boss 31 and the pressure arm driving part 52 can be decoupled, the maximum distance between the two decoupling surfaces 151 is greater than the width of the boss 31.

[0054] Therefore, when the door is in a closed state, the lifting plate mechanisms on both sides have a pushing arm 5 pressed by the side of the door, and a pressing arm driving part 52 will move away from the boss 31 when rotating along the unhooking surface 151. Based on the movable offset of the unhooking 15 at the unhooking movable opening, a certain contact interval will be retained between the pressing arm driving part 52 and the boss 31.

[0055] When one of the door bodies is opened, the pushing arm 5 on the side of the opened door body will cause the water baffle 2 on that side to drop due to the loss of lateral pressure, and then the door body is pushed to the other lifting plate mechanism and presses the pushing arm 5 on that side, so that the pushing arms 5 on both sides of the boss 31 on the rotating shaft 3 on that side are subjected to the lateral pressure, so that the pressure arm driving parts 52 on both sides of the boss 31 move along the unhooking surface 151, and finally unhooking occurs, that is, the pressure arm driving parts 52 on both sides lose the driving contact with the boss 31, and the lifting arm 4 on this side loses the driving effect of the boss 31, so that the water baffle 2 completely loses the support of the lifting arm 4, and finally the water baffle 2 is automatically lowered as a whole.

[0056] Preferably, the surface 52a of the pressure arm driving part 52 in contact with the dehooking surface 151 and the dehooking surface are spiral surfaces that fit each other.

[0057] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
