Description

Technical Field

[0001] This utility model belongs to the field of guide rail technology, specifically relating to a shower room guide rail anti-derailment device. Background Technology

[0002] A shower room mainly refers to a separate shower enclosure that can separate the shower area through a partition structure, thereby preventing water from splashing into various parts of the room during showering and significantly saving interior space in the bathroom. It also reduces heat loss during showering in winter. In current technology, people often use sliding doors installed on sliding rails to separate the shower room from the bathroom, thus forming an independent shower area.

[0003] Existing shower enclosure slide rails typically work in conjunction with silent rollers installed on the sliding door to open and close the door. After prolonged use, the silent rollers wear down due to friction with the slide rail, making them prone to detaching from the slide rail when subjected to lateral forces, which is inconvenient for users. Utility Model Content

[0004] The purpose of this utility model is to provide a shower room guide rail anti-derailment device with a simple structure and reasonable design in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A shower room guide rail anti-derailment device includes a rail with an opening at the top, the top of the side walls of the rail are bent inward to form a retaining plate, the bottom wall of the retaining plate is provided with an upper limit groove, a movable plate that can slide along the height direction of the rail is provided in the rail, the lower surface of the movable plate is fixed to the bottom wall of the rail by an elastic connector, and the upper surfaces of both sides of the movable plate are provided with lower limit grooves that are aligned with the upper limit groove;

[0007] It also includes a support plate for connecting the sliding door. Multiple sets of equidistant ear plates are installed on the lower surface of the support plate along the length of the support plate. A sleeve is fixedly connected between two ear plates in each set. An adjusting shaft is slidably connected to both ends of the sleeve. A second spring is fixedly connected between the ends of the two adjusting shafts located in the inner cavity of the sleeve. A silent wheel is rotatably connected to the end of the adjusting shaft located outside the sleeve. The size of the circumference of the silent wheel is adapted to the inner cavity of the upper limit groove and the lower limit groove.

[0008] As a further optimization of this utility model, mounting plates are fixedly connected to both sides of the bottom end of the track, and multiple fixing holes are equidistantly distributed along the length direction of the mounting plate on the mounting plate.

[0009] As a further optimization of this utility model, the elastic connector includes a slide tube whose bottom end is fixedly connected to the bottom wall of the inner cavity of the track, a slide rod whose top end is slidably connected to the top end of the slide tube, the top end of the slide rod being fixed to the lower surface of the movable plate, and a first spring provided at one end of the slide rod located in the inner cavity of the slide tube, the two ends of the first spring being fixedly connected to the slide rod and the inner wall of the slide tube respectively.

[0010] As a further optimization of this utility model, the upper surface of the movable plate between the two lower limiting grooves protrudes upward to form a guide protrusion, and the middle section of the sleeve is recessed inward to form a guide groove with an annular structure.

[0011] As a further optimization of this utility model, the support plate has a rectangular plate structure, the width of the support plate is adapted to the width of the track, and water-blocking strips for fitting against the outer walls of the track are fixedly connected to both sides of the support plate.

[0012] As a further optimization of this utility model, a connecting hole is provided at the center of the silent wheel, and a connecting shaft that is rotatably connected to the silent wheel passes through the connecting hole. After the connecting shaft passes through the silent wheel through the connecting hole, it is fixed to the end of the adjusting shaft away from the second spring.

[0013] The beneficial effects of this utility model are as follows: After installation, the silent wheel is engaged between the upper limit groove on the bottom wall of the card plate and the lower limit groove on the upper surface of the movable plate. Since the bottom wall of the movable plate is connected to the bottom wall of the track through the slide tube, the first spring and the slide rod, when the silent wheel wears out due to long-term use, the first spring can push the movable plate up through the slide rod, so that the upper and lower sides of the silent wheel are always in contact with the inner walls of the upper limit groove and the lower limit groove, so as to prevent the silent wheel from easily slipping out of the track when subjected to lateral force after wear, which is convenient for users.

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example

[0023] like Figure 1 - Figure 6 As shown, a shower room guide rail anti-derailment device includes a rail 1 with an opening at the top, and mounting plates 2 are fixedly connected to both sides of the bottom end of the rail 1. The mounting plates 2 have multiple fixing holes 3 evenly distributed along the length of the mounting plates 2, so that the rail 1 can be fixedly installed on the shower room wall after the external fixing bolts pass through the fixing holes 3.

[0024] The top of the side walls on both sides of the track 1 are bent inward to form a retaining plate 4. An upper limit groove 5 is provided on the bottom wall of the retaining plate 4. A movable plate 6 that can slide along the height direction of the track 1 is provided inside the track 1. The lower surface of the movable plate 6 is fixed to the bottom wall of the track 1 by an elastic connector. The elastic connector includes a slide tube 7 whose bottom end is fixedly connected to the bottom wall of the inner cavity of the track 1. A slide rod 9 is slidably connected to the top end of the slide tube 7. The top end of the slide rod 9 is fixed to the lower surface of the movable plate 6. A first spring 8 is provided at one end of the slide rod 9 located in the inner cavity of the slide tube 7. The two ends of the first spring 8 are fixedly connected to the slide rod 9 and the inner wall of the slide tube 7, respectively. When the movable plate 6 is subjected to downward pressure, the slide rod 9 will slide into the inner cavity of the slide tube 7, thereby squeezing the first spring 8 installed inside the slide tube 7 to contract, so that the movable plate 6 slides down along the inner cavity of the track 1.

[0025] The upper surfaces of both sides of the movable plate 6 are provided with lower limit grooves 11 that are aligned with the upper limit grooves 5. The upper surface of the movable plate 6 between the two lower limit grooves 11 protrudes upward to form a guide protrusion 10.

[0026] It also includes a support plate 12 for connecting the sliding door. The support plate 12 has a rectangular plate structure and the width of the support plate 12 is adapted to the width of the track 1. Water-blocking strips 13 for fitting against the outer walls of the track 1 are fixedly connected to both sides of the support plate 12. When the sliding door is closed, the water-blocking strips 13 can work with the support plate 12 to seal the top opening of the track 1, so as to avoid water splashing into the track 1 during showering.

[0027] Multiple sets of equidistant ear plates 14 are installed on the lower surface of the support plate 12 along the length of the support plate 12. A sleeve 15 is fixedly connected between two ear plates 14 in each set. The middle section of the sleeve 15 is recessed inward to form a guide groove with an annular structure, which is used to cooperate with the guide protrusion 10 to guide the shower room sliding door.

[0028] Both ends of the sleeve 15 are slidably connected to adjusting shafts 16. A second spring 17 is fixedly connected between the two ends of the adjusting shafts 16 located in the inner cavity of the sleeve 15. A mute wheel 18 is provided at the end of the adjusting shaft 16 located outside the sleeve 15. A connecting hole is opened in the center of the mute wheel 18. A connecting shaft 19 rotatably connects to the mute wheel 18 through the connecting hole. After the connecting shaft 19 passes through the mute wheel 18 through the connecting hole, it is fixed to the end of the adjusting shaft 16 away from the second spring 17, so that the mute wheel 18 can be rotatably connected to the adjusting shaft 16 through the connecting shaft 19. The size of the circumference of the mute wheel 18 is adapted to the inner cavity of the upper limit groove 5 and the lower limit groove 11, so that the circumference of the mute wheel 18 can be installed in the upper limit groove 5 and the lower limit groove 11.

[0029] It should be noted that, in use, this shower room guide rail anti-derailment device involves first installing the rail 1 onto the shower room floor and wall through the fixing holes 3 on the mounting plate 2. Then, the support plate 12 is installed at both ends of the shower room sliding door. The adjusting shaft 16 is then pressed into the sleeve 15, compressing the second spring 17 to adjust the distance between the two silent wheels 18 until the distance between the two silent wheels 18 on the opposite side is less than the width of the inner cavity of the top opening of the rail 1. At this point, the silent wheels 18 are inserted into the rail 1, and the movable plate is pressed... 6. Move down. When the top of the silent wheel 18 moves below the plate 4, release the silent wheel 18 so that the silent wheel 18 is reset under the elastic force of the second spring 17 and is locked between the upper limit groove 5 and the lower limit groove 11. The installation of the sliding door is then completed. When the silent wheel 18 wears down due to long-term friction, the first spring 8 can push the movable plate 6 up through the slide rod 9 so that the upper and lower sides of the silent wheel 18 are always in contact with the inner walls of the upper limit groove 5 and the lower limit groove 11. This is to prevent the silent wheel 18 from slipping out of the track 1 after wear.

[0030] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
