[0039] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings. The same parts are represented by the same figure numbers. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0040] like Figure 1-4 and Figure 12-14 As shown, an upper beam assembly of a shower door device provided by an embodiment of the utility model includes an upper beam 1 with a guide groove 115 , an upper roller 2 installed in the guide groove 115 , and a connecting shaft 3 for connecting with a shower door 7 .

[0041] The notch of the guide groove 115 is located at the bottom surface of the upper cross beam 1 , the upper end of the connecting shaft 3 is located in the guide groove 115 , the upper roller 2 is mounted on the upper end of the connecting shaft 3 , and the lower end of the connecting shaft 3 extends out from below the guide groove 115 .

[0042] At least one side of the notch of the guide groove 115 is provided with an anti-drop buckle 116 for preventing the upper roller 2 from falling.

[0043] The upper crossbeam assembly provided by the utility model is used in a shower door device, and is used as an upper crossbeam assembly of a door frame, and is used for assembling with the top of a shower door 7 .

[0044] like Figure 12-13 As shown, the door frame includes a threshold beam 5, two side frames 6 and an upper crossbeam 1. The threshold beam 5 is used to be installed on the floor of the bathroom. The threshold beam 5 has a guide rail for cooperating with the lower roller at the bottom of the shower door 7. The two side frames 6 are connected to the left and right ends of the threshold beam 5 and fixed to the wall. The upper crossbeam 1 is connected to the top of the two side frames 6.

[0045] Of course, in some special scenarios, the upper cross beam 1 can be used alone without cooperating with the side frame 6. That is, in some scenarios, the shower door device is no longer specially configured with the side frame 6, and only the threshold beam 5 and the upper cross beam 1 are required.

[0046] The upper beam assembly provided by the utility model comprises an upper beam 1, an upper roller 2 and a connecting shaft 3. The upper beam 1 is in an elongated strip shape and has a guide groove 115 opening downward, the guide groove 115 extends along the length direction of the upper beam 1 and is used to assemble the upper roller 2.

[0047] The upper roller 2 is assembled in the guide groove 115 . When the shower door 7 moves linearly, the upper roller 2 rolls in the guide groove 115 to reduce friction and also reduce or prevent the shower door 7 from shaking in a direction perpendicular to the upper beam 1 .

[0048] The connecting shaft 3 is used to connect the upper roller 2 and the shower door 7. The upper end of the connecting shaft 3 extends into the guide groove 115. The upper roller 2 is installed on the upper end of the connecting shaft 3 and can rotate. The lower end of the connecting shaft 3 extends below the guide groove 115 to be connected to the top edge 71 of the shower door 7.

[0049] When the lower roller of the shower door 7 is separated from the upper guide rail of the threshold beam 5 and descends, the shower door 7 will descend as a whole, and the upper roller 2 will slide down in the guide groove 115. In order to prevent the upper roller 2 from sliding down and separating from the guide groove 115, an anti-drop buckle 116 is provided at the notch of the guide groove 115, which plays a role in preventing the upper roller 2 from falling down and separating from the guide groove 115, thereby improving the stability of the structure and the safety of use.

[0050] The anti-drop buckle 116 is arranged on the inner surface of the lower end of the groove wall of the guide groove 115, which can be a retaining edge, a retaining bar, a convex rib or a flange, etc. The anti-drop buckle 116 extends toward the middle of the guide groove 115, reduces the notch width of the guide groove 115, and plays a role in preventing the upper roller 2 from falling.

[0051] The anti-drop buckle 116 may be integrally arranged on the inner side of the groove wall of the guide groove 115 , or may be connected to the groove wall of the guide groove 115 by using a fastener.

[0052] An anti-dropout buckle 116 may be provided at the lower end of a groove wall on one side of the guide groove 115 , or anti-dropout buckles 116 may be provided at the lower ends of groove walls on both sides of the guide groove 115 .

[0053] As required, an opening or a detachable cover plate may be provided at the top of the upper cross beam 1 so as to assemble the upper roller 2 from the top of the upper cross beam 1 .

[0054] During installation, the connecting shaft 3 is pre-installed on the top edge of the shower door 7. After the threshold beam 5, the side frame 6 and the upper crossbeam 1 are installed in place, the upper end of the shower door 7 is inserted into the guide groove 115, and then the lower roller of the shower door 7 is matched to the guide rail of the threshold beam 5, and the shower door 7 is allowed to fall naturally to complete the preliminary installation. At this time, the upper end of the connecting shaft 3 is in the guide groove 115, and then the upper roller 2 is installed on the corresponding connecting shaft 3 from above to complete the installation of the upper roller 2.

[0055] The number of upper rollers 2 and connecting shafts 3 can be set as needed. Generally, a set of upper rollers 2 and connecting shafts 3 are respectively configured at both ends of a shower door 7.

[0056] Generally, the number of the guide grooves 115 corresponds to the number of the shower doors 7 .

[0057] In one embodiment, anti-drop buckles 116 are respectively provided on both sides of the notch of the guide groove 115 to further enhance the effect of preventing the upper roller 2 from falling.

[0058] The two anti-tripping buckles 116 do not contact each other, and a passage for the connecting shaft 3 to pass through is formed between the two.

[0060] In this embodiment, a limit buckle 117 is provided in the guide groove 115, and the limit buckle 117 is located above the upper roller 2 to stop the upper roller 2 from moving upward. When the shower door 7 is moved upward, when the upper roller 2 is stopped by the limit buckle 117, it indicates that the upper roller 2 has moved upward to the limit position.

[0061] The limiting buckle 117 can be a baffle, a baffle bar, a convex rib, etc. arranged on the groove wall of the guide groove 115.

[0062] The distance between the limit buckle 117 and the anti-drop buckle 116 is greater than the thickness of the upper roller 2 along the axial direction, and the upper roller 2 has a certain vertical movable space between the limit buckle 117 and the anti-drop buckle 116 to meet the needs of adjusting the shower door 7.

[0071] In one embodiment, if Figure 2 and Figure 4 As shown, two guide grooves 115 are provided in the upper cross beam body 11 at intervals along the width direction.

[0072] The upper cross beam body 11 includes a cross beam top plate 111 and a first groove wall 112 , a second groove wall 113 and a third groove wall 114 which are connected to the bottom of the cross beam top plate 111 and are arranged in sequence.

[0073] Anti-drop buckles 116 are respectively provided at the lower ends of the first groove wall 112 and the third groove wall 114 .

[0074] A baffle plate 13 is detachably connected to the bottom of the second groove wall 113 , and both ends of the baffle plate 13 extend to below the two guide grooves 115 .
