If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0021] In the description of the present invention, unless otherwise clearly defined, the terms such as setting, installing, connecting, etc. should be understood in a broad sense, and the technical personnel in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution. At the same time, the various technical features in the invention can be combined interchangeably without conflicting with each other.

[0022] In the existing shower room sliding door, the traditional structure is that the sliding glass door and the fixed glass door are staggered in the front-to-back direction. Generally, the sliding glass door is arranged at the rear side of the fixed glass door (closer to the inner side of the shower room), and then the sliding glass door moves back and forth along the left and right direction under the guidance of the guide rail to realize the opening and closing of the shower room door. However, since the moving track of the sliding glass door is a straight line, when the sliding glass door is closed, a water retaining structure needs to be arranged at the front side of the sliding glass door. The water retaining effect of this water retaining structure is not ideal, and the sliding glass door and the fixed glass door that are staggered from each other are not beautiful in terms of product appearance.

[0023] To this end, the present invention provides a shower room sliding door structure, which changes the moving track of the sliding glass door so that after the sliding glass door moves into place, the sliding glass door can be displaced in the front-to-back direction, so that the fixed glass door and the sliding glass door can be coplanar, so that the side of the sliding glass door and the side of the fixed glass door can be used for sealing, so that the water blocking effect is better. At the same time, because the sliding glass door and the fixed glass door are coplanar in the closed state, the product is more beautiful. Specifically, refer to Figure 1 to Figure 6 : A lower rail type shower room sliding door comprises a column, a fixed glass door, and a lower rail 100 located at the lower part of the fixed glass door, wherein the left and right ends of the lower rail 100 are fixedly connected to the column. A sliding glass door 200 is slidably arranged on the lower rail 100, and the sliding glass door can slide left and right relative to the fixed glass door. A lower frame 210 is fixedly arranged on the lower side of the sliding glass door 200, and the lower frame 210 comprises a cavity 220, and a pulley block 300 is arranged in the cavity 220, and the pulley block 300 comprises a wheel frame 310 and a roller 320, and the roller 320 is mounted on the wheel frame 310, and the roller 320 is slidably connected to the lower rail 100; the wheel frame 310 is movably connected to the lower frame 210, and the lower frame 210 can move forward and backward relative to the wheel frame 310.

[0024] When the sliding glass door 200 is in the starting position (the shower room is in the open state), the sliding glass door 200 is located behind the fixed glass door, and the sliding glass door 200 and the fixed glass door are in an overlapping state; then the sliding glass door 200 is pulled hard to move in the left and right directions, and when the sliding glass door 200 moves in the left and right directions, the wheel frame 310 keeps moving in a straight line; when the sliding glass door 200 is about to move to the end position (the shower room is in the closed state), the lower frame 210 moves forward and backward relative to the wheel frame 310, so that the sliding glass door 200 can move forward synchronously, so that the sliding glass door 200 originally located behind the fixed glass door can move forward, and finally when the sliding glass door 200 reaches the position completely, the sliding glass door 200 is just flush with the fixed glass door.

[0025] After adopting the above technical solution, since the sliding glass door 200 can move forward and backward relative to the lower guide rail 100, the sliding glass door 200 can be coplanar with the fixed glass door in the closed state, thereby improving the waterproof performance and the simplicity of the appearance of the shower room. At the same time, the pulley block 300 is integrally built into the lower frame 210 of the sliding glass door 200, and the relative movement of the lower frame 210 and the wheel frame 310 is used to realize the movement of the sliding glass door 200, further improving the simplicity and aesthetics of the shower room.

[0026] See also Figure 2 As a further preferred embodiment, a swing arm 400 is provided on the pulley block 300, one end of the swing arm 400 is hinged to the lower frame 210, and the other end is hinged to the wheel frame 310. In this embodiment, when the sliding glass door 200 moves into position, the swing arm 400 triggers the lower frame 210 to swing, so that the sliding glass door 200 can move forward and backward, simplifying the structure of the shower room. Furthermore, there are two swing arms 400, and the two swing arms 400, the lower frame 210 and the wheel frame 310 form a parallel four-bar linkage mechanism, so that the lower frame 210 is more stable when moving forward and backward, and the structure is simple.

[0027] As a further preferred embodiment, the middle of the wheel frame 310 is provided with an installation cavity 311, and the end of the swing arm 400 is sleeved in the installation cavity 311. By using the installation cavity 311, the end of the swing arm 400 can be set in the wheel frame 310, so that when the wheel frame 310 and the lower frame 210 are close to each other, the two can fit together in the front-to-back direction, thereby making the sliding glass door 200 closer to the fixed glass door when the shower room is opened, reducing the overall thickness of the shower room in the front-to-back direction, and making the product more beautiful. In addition, during use, the gravity of the sliding glass door will press on the lower frame 210, and the force of the lower frame 210 is transmitted to the wheel frame 310 through the swing arm 400. Therefore, the end of the swing arm 400 is sleeved in the installation cavity 311, so that the upper and lower end faces of the swing arm 400 can abut against the wheel frame 310, thereby enhancing the mechanical structure and improving the life of the product.

[0028] In order to trigger the swing arm 400 to drive the sliding glass door 200 to move forward after the shower room is in place, further as a preferred embodiment, the lower guide rail 100 includes a guide section 110, and the swing arm 400 also includes a guide rod 410, and the guide rod 410 abuts against the guide section 110. It can be understood that the guide section 110 includes a straight track and an arc track, and the arc track is a curved shape in the front-to-back direction. The shape of the guide section 110 determines the moving track of the sliding glass door 200. When the shower room is open, the sliding glass door 200 moves horizontally in the left and right directions basically along a straight line trajectory; when the sliding glass door 200 reaches the closed state, the guide rod 410 cooperates with the guide section 110 to make the swing arm 400 swing forward and backward. Since one end of the swing arm 400 is hinged to the lower frame 210, the lower frame 210 is also displaced in the front and back directions under the drive of the swing arm 400, thereby enabling the sliding glass door 200 to move forward when the shower room is closed, and finally form a coplanar shape with the fixed glass door.

[0029] As a further preferred embodiment, the guide rod 410 is provided with a clamping wheel 420, and the clamping wheel 420 is connected to the guide section 110. By clamping the guide section 110 with the clamping wheel 420, the swing arm 400 is made more stable and smooth when swinging, and the force is more balanced.

[0030] As a further preferred embodiment, an elastic member 430 is further provided between the swing arm 400 and the lower frame 210. When the sliding glass door 200 is in a closed state, the elastic member 430 is in a stretched state. The elastic force is used to provide a certain damping for the sliding glass door 200 when closing the door, so that the sliding glass door is more gentle when closing the door, and the collision between the sliding glass door and the column when moving forward is reduced. At the same time, when the sliding glass door 200 is opened, the elastic member 430 provides an assist in opening the door, so that the opening of the sliding glass door 200 is easier and the user experience is improved. Moreover, the elastic member 430 can provide a pulling force for the sliding glass door 200 when it moves horizontally in the left and right directions, so that the sliding glass door 200 has a tendency to be closely attached to the fixed glass door, thereby improving the sliding reliability of the sliding glass door.

[0031] See also Figure 3 As a further preferred embodiment, the upper surface of the lower frame 210 includes a glass groove 211 and an installation opening 212, the installation opening 212 is communicated with the cavity 220, and a cover plate is further provided on the lower frame 210, the cover plate is buckled with the lower frame 210, and the cover plate covers the installation opening 212. The sliding glass door 200 is fixed in the glass groove 211, and the pulley block 300 is conveniently installed in the cavity 220 through the installation opening 212. Since the installation opening is arranged upward, water will flow along the glass door to the lower frame 210 during use, so the cover plate can block the water outside the lower frame to prevent water from penetrating into the cavity 220. In order to further improve the waterproof effect, the cover plate is relatively inclined, and when water flows downward from the glass door, it can gradually flow downward along the inclined cover plate, thereby improving the drainage performance.

[0032] See also Figure 4 , Figure 6 As a further preferred embodiment, the shower room further comprises an upper guide rail 500, wherein the upper guide rail 500 is fixed above the column, and the sliding glass door 200 comprises an upper frame 230, wherein the upper frame 230 is slidably connected to the upper guide rail 500. In this embodiment, the gravity of the sliding glass door 200 is mainly borne by the lower guide rail 100, and the moving track of the sliding glass door 200 is also mainly guided by the lower swing arm. Therefore, by adding the upper guide rail 500 to the shower room, the upper guide rail 500 is used to assist in guiding and limiting the movement of the sliding glass door 200, thereby improving the smoothness and reliability of the movement of the sliding glass door 200.

[0033] As a further preferred embodiment, the bottom surface of the upper guide rail 500 is provided with a guide groove 510, and the guide groove 510 includes a curved section 511, and the curved section 511 is bent along the front-back direction; the upper frame 230 is provided with a positioning pin 231, and the positioning pin 231 is inserted into the guide groove 510. The curved section 511 corresponds to the guiding section 110, and when the sliding glass door 200 moves, the upper end is guided by the limiting position of the guide groove 510, and the lower end is guided by the lower guide rail, so that the movement of the sliding glass door 200 is more stable and reliable.

[0034] See also Figure 5 , Figure 6 As a further preferred embodiment, a guide seat 600 is provided at the end of the upper guide rail 500, a stopper 610 is provided on the guide seat 600, a stopper groove 232 is provided on the upper frame 230, and the stopper block 610 is inserted into the stopper groove 232. As mentioned above, in this embodiment, the gravity of the sliding glass door 200 is mainly pressed on the lower pulley block 300, and the sliding glass door 200 has a tendency to tip over forward after installation. If the sliding glass door is guided and limited by the positioning pin 231 in the upper frame 230 alone, the safety is relatively low. To this end, the present solution adds a guide seat 600 at the end of the upper guide rail 500, the guide seat 600 can be fixedly set on the fixed glass door, and the guide seat 600 is located at the end away from the column, and the guide seat 600 is provided with a limit block 610 extending downward, and a limit groove 232 substantially equal to the length of the sliding glass door is correspondingly provided in the upper frame 230. When the sliding glass door 200 moves linearly along the left and right directions, the limit block 610 can be inserted into the limit groove 232, and the limit block 610 and the positioning pin 231 are used to provide a limit and guide function for the sliding glass door 200, so that the sliding glass door 200 is more stable and smooth when moving horizontally. When the sliding glass door 200 moves to close, the limit block 610 is separated from the limit groove 232, and the limit block 610 will not affect the forward and backward movement of the sliding glass door 200. The preferred embodiments of the present invention are specifically described above, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
