Description

Technical Field

[0001] This utility model relates to a shower room, particularly a double sliding door shower room. Background Technology

[0002] Shower room sliding doors typically open and close by sliding left and right. Chinese utility model patent CN203769514U discloses a shower room guide rail anti-derailment device. This device is installed at both ends of the shower room sliding door guide rail. A roller assembly, including pulleys and connecting blocks, is slidably installed within the guide rail. The sliding door panel is fixedly connected to the connecting blocks. The anti-derailment device includes an anti-derailment limiting block and a pulley buffer block. The anti-derailment limiting block is fixedly inserted at both ends of the shower room sliding door guide rail and includes a fixing block and a guide anti-derailment track. The guide anti-derailment track is fixedly connected to one end of the fixing block. The fixing block is fixedly installed within the shower room sliding door guide rail. The guide anti-derailment track has an anti-derailment track groove that communicates with the track groove of the shower room sliding door guide rail. When the pulley moves to the end of the shower room sliding door guide rail, the pulley enters the anti-derailment track groove for anti-derailment braking. However, in actual use, when the sliding door hits an object and stops moving, the glass door will jump due to inertia. Since the anti-detachment track groove is set with the opening facing upward, even if an anti-detachment track groove is added to prevent it from detaching, the glass door may cause the pulley to jump off the guide rail while jumping, which may cause an accident. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a buffer double sliding door to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The solution to the technical problem of this utility model is: a buffer double sliding door, including a crossbeam and a sliding door. The sliding door is slidably connected to the crossbeam via a roller assembly. The upper end face of the crossbeam is provided with a guide rail. The crossbeam includes a cavity and an opening. The opening extends along the direction of the guide rail and communicates with the cavity. A buffer is provided at the end of the crossbeam and is installed in the cavity. The roller assembly includes a wheel frame, a wheel body, and an end cap (330). The wheel body is installed on the wheel frame and is slidably connected to the guide rail. The end cap (330) is detachably connected to the wheel frame. A hook is provided on the lower side of the end cap (330). The hook extends from the opening into the cavity of the crossbeam and is connected to the buffer.

[0005] The beneficial effects of this utility model are: by setting a hook body below the end cover (330), the hook body can hook the crossbeam to achieve the effect of preventing jumping. At the same time, the hook body is connected to the buffer. When the hook body contacts the buffer, the buffer can slow down and buffer the movement of the sliding door.

[0006] As a further improvement to the above technical solution, the hook body is L-shaped and can abut against the upper inner wall of the cavity of the crossbeam.

[0007] As a further improvement to the above technical solution, the outer side of the hook body is covered with anti-collision rubber. By adding anti-collision rubber, the hook body can be prevented from directly contacting the crossbeam, reducing friction noise and extending service life.

[0008] As a further improvement to the above technical solution, the end cap (330) is located on the outside of the wheel body, and the corresponding opening is located on the outside of the guide rail. When the end cap (330) is fixedly installed on the roller assembly, it also allows the hook to pass through the opening and hook onto the crossbeam.

[0009] As a further improvement to the above technical solution, the wheel is a bearing wheel, the wheel includes an inner ring with a through hole, the wheel frame includes a base and an adjusting seat, the adjusting seat is vertically connected to the base, and the adjusting seat is fixedly connected to the wheel through the through hole. The adjusting seat allows for adjustment of the relative installation height of the sliding door, thereby enabling the shower room to be leveled.

[0010] As a further improvement to the above technical solution, the base includes an inner cavity in which an adjusting seat is located. An adjusting bolt is provided on the upper side of the base, and the adjusting bolt passes through the base and is threadedly connected to the adjusting seat. By rotating the adjusting bolt through the threaded connection between the adjusting bolt and the adjusting seat, the adjusting seat can be raised or lowered.

[0011] As a further improvement to the above technical solution, a pressure plate is provided on the upper side of the substrate, which covers the adjusting bolt. The pressure plate can prevent the adjusting bolt from coming out.

[0012] As a further improvement to the above technical solution, a mounting post is provided on the inner side of the substrate, and the sliding door is fixed on the mounting post. The sliding glass door is directly fixed to the roller assembly, and the roller assembly is used to cushion the glass door.

[0013] As a further improvement to the above technical solution, the end of the crossbeam is provided with a cover, and the buffer is secured to the cover. Using the cover simplifies the installation of the buffer.

[0014] As a further improvement to the above technical solution, the sliding door has two panels, the guide rails have two tracks, and the opening is located between the two guide rails. Positioning the opening between the two guide rails makes the beam structure simpler and more compact. Attached Figure Description

Preferred embodiments of this utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, enabling a person to intuitively and vividly understand each technical feature and overall technical solution of this utility model, but they should not be construed as limiting the protection scope of this utility model.

[0024] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0027] There are many types of shower enclosures, one of which is a simple design without pillars or a doorway. Because it lacks a metal door frame, it appears more minimalist and is popular with some consumers. This type of frameless shower enclosure typically uses a sliding door structure, where the glass door is suspended from a crossbeam by wheels, and the relative rolling of the wheels and the crossbeam allows the glass door to move back and forth. Due to its simple structure, when the glass door reaches the end, inertia may cause it to jump up. Furthermore, since the wheels are positioned above the crossbeam, if the glass door is adjusted upwards along with the wheels, it may detach from the crossbeam, creating an unnecessary risk.

[0028] Therefore, this utility model provides an improved shower room sliding door with a buffer. By optimizing the connection structure between the wheels and the crossbeam, the glass door will not jump off the crossbeam even after it has moved into place. Specifically, refer to... Figures 1-5 :

[0029] A buffered double sliding door includes a crossbeam 100 and a sliding door 200. The sliding door is installed on the crossbeam 100 by suspension, and the sliding door 200 is slidably connected to the crossbeam 100 via two roller sets 300. The crossbeam 100 is a profile structure, with a guide rail 110 on its upper end. The crossbeam 100 includes a cavity 120 and an upward-opening opening 130. The opening 130 and the guide rail 110 extend along the length of the crossbeam, and the opening 130 communicates with the cavity 120. Buffers 400 are provided at both the beginning and end of the crossbeam 100. The buffers 400 are installed in the cavity 120, meaning they are not visible from the outside. The buffers 400 can be gas spring structures, commonly called dampers or door closers, and include a trigger end. The roller assembly 300 includes a wheel frame 310, a wheel body 320, and an end cap (330) 330. The wheel frame 310 is the foundation of the roller assembly 300. The sliding door 200 is fixedly installed on the wheel frame 310. The wheel body 320 is rotatably connected to the wheel frame 310 and is slidably connected to the guide rail 110. The end cap (330) 330 is detachably connected to the wheel frame 310. In addition, a hook 340 is fixedly provided on the lower side of the end cap (330) 330. The hook 340 can extend from the opening 130 into the cavity 120 of the crossbeam and is connected to the trigger end of the buffer 400.

[0030] When installing the shower room of this utility model, the buffer 400 is first pre-installed at the end of the crossbeam 100, and then the crossbeam 100 is fixed together with it to the wall; then the wheel frame 310 of the roller assembly 300 is also pre-fixed to the sliding door 200, and the end cap (330) 330 is not installed on the wheel frame 310 at this time; then the sliding door 200 and the roller assembly 300 are hung from top to bottom on the crossbeam 100, so that the wheel body 320 is connected to the guide rail 110; after installation, the sliding door 200 can move back and forth on the crossbeam 100 relatively smoothly; finally, the end cap (330) 330 is installed on the wheel frame 310. When installing the end cap (330) 330, the hook body 340 is inserted from the opening 130 into the cavity 120, so that the hook body 340 can be connected to the trigger end of the buffer 400 when it moves to the end of the crossbeam 100.

[0031] After installation, when the sliding door 200 moves to the end of the crossbeam 100, the connection between the hook 340 and the buffer 400 is used to slow down the sliding door 200, effectively reducing the risk of the sliding door 200 jumping due to inertia.

[0032] As a further preferred embodiment, the hook 340 is L-shaped and can abut against the upper inner wall of the cavity 120 of the crossbeam 100. It is understood that the width of the hook 340 is greater than the width of the opening 130. When installing the end cap (330) 330, the hook 340 is first inserted into the cavity 120 at an angle. After the hook 340 enters the cavity 120, the end cap (330) 330 is straightened. Finally, the end cap (330) 330 is fixed to the wheel frame 310 with bolts. After the end cap (330) 330 is fixed, the relative position of the hook 340 is also fixed. At this time, the hook 340 hooks onto the upper side wall of the cavity 120. The hook 340 can prevent the roller assembly 300 from moving upwards. At the same time, since the wheel 320 presses on the crossbeam 100, the sliding door 200 is fixed together with the crossbeam 100 in the vertical direction. The shower room is safer and more reliable.

[0033] See Figure 4 As a further preferred embodiment, the hook body 340 is covered with an anti-collision rubber 341. The crossbeam 100 is usually made of stainless steel or aluminum alloy, while the end cap (330) 330 and the hook body 340 are usually cast iron. To avoid direct contact between the metals, the anti-collision rubber 341 is used to cover the hook body 340, which prevents the hook body from directly contacting the crossbeam, reduces friction noise, and extends service life. The anti-collision rubber 341 can be made of a hard, wear-resistant plastic material.

[0034] As a further preferred embodiment, the end cap (330) 330 is located outside the wheel body 320, and the corresponding opening 130 is located outside the guide rail 110. As mentioned above, during installation, the wheel body 320 is installed before the guide rail 110, and then the end cap (330) 330 is installed onto the wheel frame 310. Therefore, by setting the positional relationship between the opening 130 and the guide rail 110, when the end cap (330) 330 is fixedly installed on the roller assembly 300, the hook 340 can pass through the opening 130 and hook onto the crossbeam 100. This makes the structure of the crossbeam 100 simpler and more compact.

[0035] See Figures 2-4As a further preferred embodiment, the wheel 320 is a bearing wheel, comprising an inner ring and an outer ring connected by ball bearings. The inner ring includes a through hole 321. The wheel frame 310 includes a base 311 and an adjusting seat 312, which is vertically connected to the base 311 and fixedly connected to the wheel 320 through the through hole 321. In use, the outer ring is connected to the guide rail 110, while the inner ring is relatively fixed on the adjusting seat 312 of the wheel frame 310. The relative rolling between the inner and outer rings enables the sliding door to move back and forth. The adjusting seat 312 can be fixed in the inner ring of the wheel 320 by an interference fit.

[0036] After installation, the base 311 is fixed together with the sliding door 200. By adjusting the relative up and down position of the adjusting seat 312, the up and down position of the sliding door 200 relative to the crossbeam 100 can be adjusted, thereby fine-tuning the installation position of the sliding door 200 to meet the horizontal requirements.

[0037] Specifically, as a preferred embodiment, the base 311 includes an inner cavity 313, the adjusting seat 312 is located in the inner cavity 313, and an adjusting bolt 314 is provided on the upper side of the base 311. The adjusting bolt 314 passes through the base 311 and is threadedly connected to the adjusting seat 312. The adjusting bolt 314 and the adjusting seat 312 form a structure equivalent to a lead screw and nut, so that when the adjusting bolt 314 is rotated, the adjusting seat 312 can move up and down. Of course, it can be understood that the inner cavity 313 has a limiting effect on the adjusting seat 312, so that the adjusting seat 312 can only move up and down relative to the base 311.

[0038] Furthermore, as a preferred embodiment, a pressure plate 315 is provided on the upper side of the base 311, which covers the adjusting bolt 314. The adjusting bolt 314 is rotatably mounted on the base 311 in the vertical direction. To prevent the adjusting bolt 314 from detaching from the base 311 during rotation, the pressure plate 315 is fixedly provided on the upper side of the base 311 to press down the adjusting bolt 314 and prevent it from detaching. It is understood that the pressure plate 315 has a through hole corresponding to the adjusting bolt 314. When adjustment is needed, a screwdriver can be inserted through the through hole to connect with the adjusting bolt 314.

[0039] As a further preferred embodiment, the inner side of the base 311 is provided with a mounting post 316, and the sliding door 200 is fixed to the mounting post 316. The installation structure of the roller assembly 300 and the sliding door 200 is also relatively simple. A glass hole is drilled in the sliding door 200, then the mounting post 316 is fitted into the glass hole, and finally the sliding door 200 is clamped in the roller assembly 300 through the fixed connection of the wheel cover and the base 311. Usually, the wheel cover and the base 311 are made of cast iron, so rubber pads can be set on the wheel cover and the base 311, and the rubber pads contact the glass door to protect it.

[0040] Furthermore, to improve the installation efficiency of the buffer and the crossbeam, as a preferred embodiment, the end of the crossbeam is provided with a cover 140, the cover 140 is provided with a locking block, and the corresponding buffer 400 is provided with a locking groove. The buffer is secured to the cover 140 by the cooperation of the locking block and the locking groove. Additionally, to facilitate adjustment of the gap between the crossbeam 100 and the wall, a sleeve can be provided outside the crossbeam 100 to adjust the distance of the crossbeam 100.

[0041] As a further preferred embodiment, the sliding door 200 has two panels, the guide rails 110 have two tracks, and the opening 130 is located between the two guide rails 110. Placing the opening 130 between the two guide rails 110 makes the structure of the beam 100 simpler and more compact.

[0042] As a further preferred embodiment, the shower enclosure also includes a water-retaining strip fixed to the ground, and a slider is provided on the water-retaining strip, with the lower part of the sliding door connected to the slider. The water-retaining strip enables dry and wet separation of the shower enclosure, while the slider makes the sliding door more stable when moving back and forth.

[0043] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
