Description

Shower door height adjustment device

technical field

The invention relates to a height adjusting device for a shower door.

Background technique

In most existing shower rooms, the shower door is hung on the upper rail. Since the shower door is generally a glass door, which is relatively heavy, after a long time, the parts hanging the shower door will be deformed, so that the shower door will fall and be clamped on the lower beam. In the guide chute, it will be more difficult to open the shower door. Some existing height adjustment devices can only be adjusted after the adjustment device or the shower room is disassembled, which is very difficult to adjust and has a complicated structure. Chinese Patent Document No. CN202559932U disclosed on December 28, 2012 a shower door height adjustment device, which includes a plurality of sliders that can slide on the upper guide rail. There is an adjustment block in the guide groove that can slide up and down in the adjustment guide groove. The end of the adjustment block protruding out of the adjustment guide groove is fixed with a shower door. Adjustment lever that slides down. It is said that the height of the shower door can be adjusted very simply and conveniently by rotating the adjustment rod to move the connecting rod upward; the height of the shower door can be adjusted, pushed and pulled through the square guide block to restrict sliding in the adjustment guide groove. It is stable and does not shake; however, this design cannot adjust the guide rail, and the shower door is inconvenient to disassemble. Therefore, it is necessary to make further improvements.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

Referring to Fig. 1-Fig. 6, a shower door height adjustment device includes an upper guide rail 1, the upper guide rail 1 is assembled on the fixed door 2 through two sets of guide rail fixing parts, and the movable door 3 is movably assembled on the upper guide rail 1 through two sets of pulley blocks , the pulley block includes large pulleys and anti-jump wheels arranged on the upper and lower sides of the upper guide rail 1, countersunk screws are eccentrically arranged on the guide rail fixing parts, large pulleys and anti-jump wheels, and the upper guide rail 1 and the movement are controlled by adjusting the position of the eccentric block The height of door 3.

The guide rail fixing part includes a fixing part eccentric block 4 and a fixing part countersunk screw 5, and the fixing part eccentric block 4 passes through a first fixing part rubber pad 6 and a fixing part rubber sleeve 7 and is rotatably assembled on one side of the fixed door 2; The eccentric block 4 of the fixing part is provided with an eccentric screw hole 4.1 of the fixing part, and the countersunk screw 5 of the fixing part passes through the upper guide rail 1 and the fixed door 2 in turn and is screwed in the eccentric screw hole 4.1 of the fixing part. The surface of the eccentric block 4 of the fixing part is also provided with a position mark and an adjustment hole, which is convenient for the user to locate and rotate the eccentric block 4 of the fixing part. The guide rail fixing part also includes a countersunk pad 10, a boss pad 9 and a second fixing part rubber pad 8 which are arranged on the other side of the fixed door 2 corresponding to the fixing part eccentric block 4, and which are sequentially passed through by the fixing part countersunk head screw 5. Wherein the upper guide rail 1 is arranged on the countersunk pad 10 and between the boss pad 9 .

The large pulley includes a large roller 11, a roller eccentric block 13 and a roller countersunk head screw 14, wherein the roller eccentric block 13 passes through a roller rubber pad 15 and a roller rubber sleeve 16 and is mounted on one side of the movable door 2, and the large roller 11 It is arranged on the other side of the dodge door 3; the roller eccentric block 13 is provided with a roller eccentric screw hole 13.1, and the roller countersunk screw 14 passes through the roller eccentric screw hole 13.1, the dodge door 3 and is screwed in the large roller 11 in turn. The surface of the roller eccentric block 13 is also provided with a position mark and an adjustment hole, which is convenient for the user to locate and rotate the roller eccentric block 13 . The rear side of the roller eccentric block 13 is matched with a decorative cover 17 corresponding to the end of the roller countersunk screw 14 . The anti-jump wheel has the same structural composition as the large pulley, and also includes a small roller 12, a roller eccentric block 13', a roller eccentric screw hole 13.1', a roller countersunk screw 14', a roller rubber pad 15' and a roller rubber sleeve 16' and The decorative cover 17'; the small roller 12 is correspondingly arranged under the big roller 11, and the size of the small roller 12 can be made smaller than the big roller 11 according to needs. The middle of the big roller 11 and the small roller 12 are respectively indented to form an upper chute 11.1 and a lower chute 12.1, wherein the upper chute 11.1 is hung on the upper side of the upper guide rail 1, and the lower side between the lower chute 12.1 and the upper guide rail 1 There is a small gap between them.

Working principle of the present invention: 1) adjust the large pulley: take out the decorative cover 17, unscrew the countersunk screw 14 of the roller, and rotate the eccentric block 13 of the roller. Since the roller eccentric screw hole 13.1 is provided on the roller eccentric block 13 (that is, not at the center position of the roller eccentric block 13), the roller eccentric block 13 changes the height position of the roller countersunk screw 14 while rotating, and the large roller 11 is affected by the roller countersunk head. Screw 14 drives to rise or fall, and dodge door 3 installation heights descends or rises thereupon. 2) Adjust the anti-jumping wheel: take out the decorative cover 17', loosen the countersunk screw 14' of the roller, and turn the eccentric block 13' of the roller. By adjusting the anti-jump wheel, the gap between the lower side of the glide groove 2.1 and the upper guide rail 1 is controlled to ensure that the anti-jump wheel is in good contact with the upper guide rail 1, which can prevent the dodge door 3 from jumping and shaking in the moving direction. 3) Adjust the guide rail fixing part: loosen the countersunk head screw 5 of the fixing part, and turn the eccentric block 4 of the fixing part. The eccentric block 4 of the fixing part changes the installation height of the countersunk head screw 5 of the fixing part while rotating, and since the upper guide rail 1 is assembled and fixed by the head screw 5 of the fixing part, the upper guide rail 1 changes with the height of the countersunk head screw 5 of the fixing part. Change, and then change the installation height of dodge door 3.
