[0063] See also Figures 3 to 9 As shown, this embodiment provides a lifting type rotating shaft shower door, including a first slide rail profile 10, a second slide rail profile 20, a lifting cylinder 30 and a rotating shaft sliding door 40, wherein:

[0064] The first slide rail profile 10 is arranged vertically, and a first cavity 11 is provided inside the first slide rail profile 10. The upper end, the lower end and one side of the first cavity 11 are all provided with openings, and a cylinder fixing member 50 is provided at the lower end port of the first cavity 11;

[0065] The second slide rail profile 20 is provided with a convex portion 21 embedded in the first cavity 11, the interior of the convex portion 21 is hollow and forms a second cavity 22, a cylinder stopper 60 is provided in the second cavity 22, and a shaft stopper 70 is provided at the upper end and the lower end of the second slide rail profile 20 respectively;

[0066] The lifting cylinder 30 is disposed in the second cavity 22, and the output rod of the lifting cylinder 30 is connected to the cylinder fixing member 50, and the cylinder body of the lifting cylinder 30 abuts against the cylinder stopper 60. The lifting cylinder 30 is used to drive the second slide rail profile 20 to rise and fall relative to the first slide rail profile 10;

[0067] A sliding door pivot profile 41 is provided on one side of the pivot sliding door 40 , and both ends of the sliding door pivot profile 41 are rotatably connected to two pivot stoppers 70 , so that the pivot sliding door 40 can rotate relative to the second slide rail profile 20 .

[0068] As a result, the pivot sliding door 40 has a lifting function, so that it can effectively avoid the shower water valve, etc., and realize that the pivot sliding door 40 can be opened 180° without obstacles. It can not only meet the function of preventing shower splashes during showering, but also can be perfectly opened close to the wall when not in use, thereby maximizing space utilization, and the overall structure is compact and beautiful in appearance.

[0069] Among them, the cylinder limiter 60 is fixed to the second slide rail profile 20 by bolts, and the position in the second cavity 22 is calculated according to the movement stroke of the lifting cylinder 30; the cylinder fixing member 50 is fixed to the bottom of the first slide rail profile 10 by bolts, and the cylinder fixing member 50 is provided with a socket for inserting the output rod of the lifting cylinder 30.

[0070] Optionally, see Figures 3 to 5 A limiting protrusion 12 is provided on the opening side of the first slide rail profile 10, and a plurality of first limiting plastic parts 80 and an anti-movement sleeve 90 abutting against the first limiting plastic part 80 are vertically provided on the limiting protrusion 12. A first groove 23 is provided on the second slide rail profile 20 at the installation position corresponding to the first limiting plastic part 80, and the first limiting plastic part 80 is interference fit with the first groove 23.

[0071] The outer surface of the first limiting plastic part 80 here is provided with a protrusion that increases friction, and only the protrusion is in close contact with the first groove 23 to prevent the rotating shaft sliding door 40 from sagging and affecting the lifting function; the anti-movement sleeve 90 is used to limit the up and down movement of the first limiting plastic part 80, and the anti-movement sleeve 90 is slightly smaller than the first limiting plastic part 80. The anti-movement sleeve 90 forms a gap with the first groove 23 to reduce friction resistance and improve the smoothness of lifting and lowering.

[0072] Optionally, see Figure 3 and Figure 6A plurality of second limiting plastic parts 100 are vertically arranged on the outer surface of the protrusion 21 , and a second groove 13 is arranged on the inner wall of the first cavity 11 corresponding to the installation position of the second limiting plastic part 100 , and the second limiting plastic part 100 is interference fit with the second groove 13 .

[0073] The second position-limiting plastic component 100 here has a similar structure to the first position-limiting plastic component 80 and is also used to prevent the pivot sliding door 40 from sagging. The second position-limiting plastic component 100 is fixed to the second slide rail profile 20 by bolt connection.

[0074] Optionally, the shaft stopper 70 is provided with a boss 71 plugged into the end of the second cavity 22 and a shaft cavity 72 rotatably connected to the end of the sliding door shaft profile 41 to ensure that the shaft sliding door 40 and the second slide rail profile 20 are reliably installed.

[0075] Further, see Figure 7 A boss 71 of the shaft stopper 70 at the lower end of the second slide rail profile 20 is provided with an avoidance hole for the output rod of the lifting cylinder 30 to pass through, and a avoidance step 73 for avoiding the cylinder fixing member 50 is provided on the boss 71.

[0076] Optionally, see Figure 3 , Figure 6 and Figure 7 The second slide rail profile 20 is provided with waterproof strips 110 extending to both sides of the sliding door shaft profile 41, and a water guide groove 74 is provided on the shaft stopper 70 located at the lower end of the second slide rail profile 20 corresponding to the installation position of the waterproof strip 110.

[0077] Among them, the waterproof strip 110 is close to the sliding door hinge profile 41, which can effectively prevent shower water from splashing out from the sliding door hinge profile 41; the water guide groove 74 is installed in conjunction with the waterproof strip 110 on the one hand, and on the other hand, it can prevent water from flowing through the plane of the hinge limiter 70 to the outside of the hinge sliding door 40 during showering.

[0078] Optionally, a soundproof pad 120 is provided on the lower surface of the shaft stopper 70 located at the lower end of the second slide rail profile 20 .

[0081] When the limit plate 140 is installed on the dust shield cover 130, the limit plate 140 forms an upper limit position for the shaft limit member 70 located at the upper end of the second slide rail profile 20, and the shaft sliding door 40 cannot be raised; when the limit plate 140 is removed, the limiting function of the limit plate 140 on the shaft limit member 70 fails, and the shaft sliding door 40 can be raised freely.

[0082] In addition, after the lifting cylinder 30 is assembled, when it is packaged and transported, the second slide rail profile 20 will automatically rise and fall relative to the first slide rail profile 10 due to the lack of the self-weight of the pivot sliding door 40. The function of the limit plate 140 is to prevent the second slide rail profile 20 from automatically rising and falling. After the pivot sliding door 40 is assembled in the shower room, the limit plate 140 can be removed and the lifting function can be restored.

[0083] Optionally, a water-blocking and sound-isolating strip 150 is provided at the lower edge of the pivot sliding door 40 to effectively isolate water and sound during showering.

[0084] Optionally, see Figure 3 and Fig. 9 The lifting hinge shower door also includes a wall profile 160, which is fixed to the wall, and the first slide rail profile 10 is embedded in the wall profile 160. Screws fixed to the first slide rail profile 10 are screwed into the side of the wall profile 160, and a cover profile 170 for hiding the screws is buckled on the wall profile 160.
