Description

Technical Field

[0001] This utility model relates to the field of bathroom door technology, and in particular to an anti-jump bathroom door pulley. Background Technology

[0002] Existing bathroom doors are generally divided into two types: sliding and hinged. Sliding bathroom doors are equipped with rollers and tracks, and the door moves by sliding the rollers on the tracks. When the bathroom door moves quickly to a braking position or is impacted, it is prone to shaking. This can cause the rollers installed on the door to bounce upwards due to external force. In severe cases (i.e., when the height of the rollers bounces exceeds the depth of the track groove), the rollers may even detach from the track, greatly affecting the stability and safety of the bathroom door. Utility Model Content

[0003] In response to the problems raised in the background technology, the purpose of this utility model is to propose an anti-jump bathroom door pulley that can limit the height of the pulley's upward bounce, preventing the pulley from jumping off the track, effectively improving the stability and safety of the bathroom door, and solving the technical problem that existing bathroom door pulleys are prone to jumping off the track when subjected to external force.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] An anti-jump bathroom door pulley includes a clamping assembly, a roller seat, a roller, and a limiting cover plate. The roller seat is connected to the clamping assembly. A roller mounting part is connected to the front end of the roller seat, and the roller is connected to the roller mounting part. A sliding groove is provided on the upper part of the roller seat. The sliding groove is recessed downwards, and the length direction of the sliding groove is parallel to the front-back direction. The front and rear ends of the sliding groove are open.

[0006] The limiting cover plate is slidably connected to the sliding groove. A slide bar is provided on the lower side of the limiting cover plate. The length direction of the slide bar is parallel to the front-back direction. The slide bar corresponds to the sliding groove. When the limiting cover plate slides completely into the sliding groove along the slide bar, the front part of the limiting cover plate is located above the roller, and the bottom surface of the front part of the limiting cover plate is higher than the top of the roller.

[0007] To further explain, the clamping assembly includes a first clamping plate and a second clamping plate. The rear of the first clamping plate has a first boss protruding rearward. The first boss has a hollow cavity with an opening at the front end. The roller seat is disposed in the cavity and fixedly connected to the first clamping plate. The second clamping plate is disposed at the rear end of the first boss and fixedly connected to the first boss.

[0008] The first clamping plate has a first snap-fit ​​groove on its upper side. The first snap-fit ​​groove is recessed downward and located near the end of the first clamping plate. The front and rear ends of the first snap-fit ​​groove are open.

[0009] The upper side of the second clamping plate is provided with a second snap-fit ​​groove. The second snap-fit ​​groove is recessed downward and located near the end of the second clamping plate. The front and rear ends of the second snap-fit ​​groove are open. The second snap-fit ​​groove corresponds to the first snap-fit ​​groove.

[0010] The upper part of the roller seat is connected to a locking block, the rear end of the locking block protrudes backward from the roller seat, and the locking block is disposed near the end of the roller seat; the locking block engages with the first locking groove and the second locking groove; the locking block is provided with the sliding groove.

[0011] To further explain, the first clamping plate has a first mounting hole through its upper side, which is located near the end of the first clamping plate; the roller seat has second mounting holes at both ends, which correspond to the first mounting holes and are both arranged in the vertical direction; the first clamping plate is fixedly connected to the roller seat by fasteners passing through the first mounting hole and the second mounting hole.

[0012] To further explain, the limiting cover plate has a receiving groove in the middle, and the front end of the receiving groove is open; a column is connected to the upper side of the first clamping plate, the column passes through the receiving groove and protrudes upward; the front end of the column has a limiting groove, the limiting groove is recessed backward, and the length direction of the limiting groove is parallel to the vertical direction.

[0013] To further explain, the first boss has a third mounting hole at both its left and right ends, and the second clamping plate has a fourth mounting hole at both its left and right ends. The fourth mounting hole corresponds to the third mounting hole and is arranged along the front-back direction.

[0014] Furthermore, the clamping assembly also includes a first rubber pad and a second rubber pad. The front and rear sides of the first rubber pad are respectively connected to the first clamping plate and the bathroom door. The rear part of the first rubber pad is provided with a second protrusion, and the shape of the second protrusion matches the shape of the first protrusion.

[0015] The front and rear sides of the second rubber pad are respectively connected to the bathroom door and the second clamping plate, and the shape of the second rubber pad matches the shape of the second clamping plate.

[0016] To further clarify, the first and second adhesive pads are made of rubber or silicone.

[0017] To further explain, the rear of the limiting cover plate is provided with a fifth mounting hole, which penetrates the limiting cover plate in the vertical direction and corresponds to the slide bar; the locking block is provided with a sixth mounting hole, which is arranged in the vertical direction and communicates with the sliding groove, and corresponds to the fifth mounting hole; the limiting cover plate is fixedly connected to the locking block by screw fasteners passing through the fifth mounting hole and the sixth mounting hole.

[0018] To further explain, the top surface of the front part of the limiting cover plate is provided with an inclined surface, which is inclined downward.

[0019] To further explain, the bottom surface of the front part of the limiting cover plate is provided with a recessed portion, which corresponds to the roller.

[0020] Compared with the prior art, the embodiments of this utility model have the following beneficial effects:

[0021] 1. By setting a limiting cover, when the roller bounces upward, it will cause the limiting cover to bounce along with it. The top surface of the front of the limiting cover will then abut against the upper end of the slide rail, thus limiting the roller's upward bounce. Furthermore, because the gap between the top surface of the limiting cover and the upper end of the slide rail is less than the depth of the slide rail roller groove, the roller's bounce height cannot exceed the depth of the slide rail roller groove, ensuring that the roller cannot jump out of the slide rail's roller groove. This effectively improves the stability and safety of the bathroom door and solves the technical problem of existing bathroom door rollers easily detaching from the slide rail when subjected to external force and bouncing upward. Moreover, by setting a sliding strip that cooperates with the sliding groove, the front and rear parts of the anti-jump bathroom door roller are more securely connected.

[0022] 2. By setting the first protrusion and the receiving cavity, the roller seat can be placed in the receiving cavity. After the first protrusion passes through the preset installation opening of the bathroom door, the first clamping plate and the second clamping plate clamp the bathroom door from the front and rear sides respectively. This allows the roller seat, the first clamping plate and the structural parts of the bathroom door to overlap, reducing the overall thickness of the three and the gap between the slide rail and the bathroom door. This makes the overall structure more compact and beautiful, and can better meet the user's needs for ultra-narrow installation.

[0023] 3. By setting the first and second rubber pads, the first and second rubber pads can be connected to the front and back sides of the bathroom door respectively. The elasticity of the first and second rubber pads can play a buffering role, effectively preventing the bathroom door from cracking when the first and second clamps are installed too tightly.

Detailed Implementation

[0042] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0043] In the description of this utility model, it should be understood that the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and 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, and therefore should not be construed as a limitation of this utility model. Furthermore, features defined with "first" and "second" may explicitly or implicitly include one or more of these features, used to distinguish descriptive features, without any order or emphasis.

[0044] like Figures 1 to 5 , Figure 17 As shown, an anti-jump bathroom door pulley includes a clamping assembly 1, a roller seat 2, a roller 3, and a limiting cover plate 4. The roller seat 2 is connected to the clamping assembly 1. A roller mounting part 21 is connected to the front end of the roller seat 2, and the roller 3 is connected to the roller mounting part 21. A sliding groove 22 is provided on the upper part of the roller seat 2. The sliding groove 22 is recessed downwards, and the length direction of the sliding groove 22 is parallel to the front-back direction. The front and rear ends of the sliding groove 22 are open.

[0045] The limiting cover plate 4 is slidably connected to the sliding groove 22. A slide bar 41 is provided on the lower side of the limiting cover plate 4. The length direction of the slide bar 41 is parallel to the front-back direction. The slide bar 41 corresponds to the sliding groove 22. When the limiting cover plate 4 slides completely into the sliding groove 22 along the slide bar 41, the front part of the limiting cover plate 4 is located above the roller 3, and the bottom surface of the front part of the limiting cover plate 4 is higher than the top of the roller 3.

[0046] In practical applications, the anti-jump bathroom door pulley is installed on the bathroom door 5, and a slide rail 6 is installed in conjunction with the bathroom door 5. The roller 3 is located in the roller groove of the slide rail 6. When installing the anti-jump bathroom door pulley, first, the roller 3 is installed on the roller mounting part 21 with screws and fasteners, and the roller seat 2 is installed on the clamping assembly 1 with fasteners; then, the clamping assembly 1 is installed on the bathroom door 5 with screws and fasteners (at this time, the roller seat 2 and the roller 3 are also installed on the bathroom door 5 together through the clamping assembly 1); then, the roller 3 is inserted into the roller groove of the slide rail 6, and the front end of the limiting cover plate 4 is inserted into the sliding groove 22 with the roller 3 facing it (at this time, it slides along the slide bar 41 and is engaged with the sliding groove 22); when the slide bar 41 is completely slid into the sliding groove 22, the front part of the limiting cover plate 4 is above the roller 3, and the bottom surface of the front part of the limiting cover plate 4 is higher than the top of the roller 3 (e.g., Figure 17 As shown), and the gap between the top surface of the front part of the limiting cover plate 4 and the upper end of the slide rail 6 is less than the depth of the roller groove of the slide rail 6.

[0047] When the roller 3 bounces upward under external force, without the limiting cover plate 4, as long as the height of the roller 3 jumps exceeds the depth of the roller groove of the slide rail 6, the roller 3 can jump out of the roller groove of the slide rail 6, which will cause the roller 3 to easily detach from the slide rail 6, seriously affecting the stability and safety of the bathroom door 5. By setting the limiting cover plate 4, when the roller 3 jumps upward, it will cause the limiting cover plate 4 to jump along with it. The top surface of the front of the limiting cover plate 4 will then abut against the upper end of the slide rail 6, thus limiting the roller 3 from jumping further upward. Furthermore, since the gap between the top surface of the front of the limiting cover plate 4 and the upper end of the slide rail 6 is less than the depth of the roller groove in the slide rail 6, the height of the roller 3's jump cannot exceed the depth of the roller groove in the slide rail 6. This ensures that the roller 3 cannot jump out of the roller groove in the slide rail 6, ultimately ensuring that the roller 3 will not detach from the slide rail 6. This effectively improves the stability and safety of the bathroom door 5 and solves the technical problem of existing bathroom door rollers easily detaching from the slide rail when subjected to external force and bouncing upward. In addition, by setting the sliding strip 41 to cooperate with the sliding groove 22, the front and rear parts of the anti-jump bathroom door roller can be more securely connected.

[0048] To further explain, there are two rollers 3 and two roller mounting parts 21, as well as two sliding grooves 22 and two slide bars 41. The sliding grooves 22 are located near the left and right ends of the roller seat 2.

[0049] like Figures 1 to 3 , Figures 6 to 8 As shown, and further explained, the clamping assembly 1 includes a first clamping plate 11 and a second clamping plate 12. The rear of the first clamping plate 11 has a first boss 111 protruding rearward. The first boss 111 has a hollow cavity 1111 inside. The front end of the cavity 1111 is open. The roller seat 2 is disposed in the cavity 1111 and fixedly connected to the first clamping plate 11. The second clamping plate 12 is disposed at the rear end of the first boss 111 and fixedly connected to the first boss 111.

[0050] The upper side of the first clamping plate 11 is provided with a first snap-fit ​​groove 112. The first snap-fit ​​groove 112 is recessed downward and located near the end of the first clamping plate 11. The front and rear ends of the first snap-fit ​​groove 112 are open.

[0051] The upper side of the second clamping plate 12 is provided with a second snap-fit ​​groove 121. The second snap-fit ​​groove 121 is recessed downward and located near the end of the second clamping plate 12. The front and rear ends of the second snap-fit ​​groove 121 are open. The second snap-fit ​​groove 121 corresponds to the first snap-fit ​​groove 112.

[0052] The upper part of the roller seat 2 is connected to a locking block 23. The rear end of the locking block 23 protrudes backward from the roller seat 2. The locking block 23 is disposed near the end of the roller seat 2. The locking block 23 is engaged with the first locking groove 112 and the second locking groove 121. The locking block 23 is provided with the sliding groove 22.

[0053] To further explain, the bathroom door 5 is a glass door, and its upper end has a pre-set mounting opening. The position of this pre-set mounting opening corresponds to the first protrusion 111, and the shape of this pre-set mounting opening matches the shape of the first protrusion 111 (e.g., Figure 14 (As shown). The thickness of the first protrusion 111 does not exceed the thickness of the bathroom door 5.

[0054] In practical applications, the bathroom door 5 is clamped and fixed between the first clamping plate 11 and the second clamping plate 12 (e.g., Figure 17 (As shown). Without the first boss 111 and the receiving cavity 1111, the roller seat 2 is connected to the front side of the first clamping plate 11, and the bathroom door 5 is clamped to the rear side of the first clamping plate 11. This results in a large overall thickness of the roller seat 2, the first clamping plate 11, and the bathroom door 5 (that is, a large distance between the roller seat 2 and the bathroom door 5), which in turn results in a large gap between the slide rail 1 and the bathroom door 5, making the overall structure bulky and unsightly. By setting the first protrusion 111 and the receiving cavity 1111, the roller seat 2 can be placed in the receiving cavity 1111, and the first protrusion 111, where the receiving cavity 1111 is located, can be placed in the preset installation opening of the bathroom door 5. Then, the first clamping plate 11 and the second clamping plate 12 clamp the bathroom door 5 from the front and rear sides respectively. This allows the roller seat 2, the first clamping plate 11 and the bathroom door 5 to overlap, reducing the overall thickness of the three. The gap between the slide rail 1 and the bathroom door 5 is also correspondingly smaller, making the overall structure more compact and aesthetically pleasing, and better meeting the user's needs for extremely narrow installation.

[0055] Meanwhile, since the roller seat 2 is placed inside the receiving cavity 1111, when the user looks up at the slide rail 1, the connection structure between the roller seat 2 and the first clamping plate 11 is also hidden inside the receiving cavity 1111, so the structure does not appear cluttered, thus making the user's visual experience better.

[0056] Specifically, when installing the clamping assembly 1 and the roller seat 2, first, the rear part of the roller seat 2 faces the front opening of the receiving cavity 1111, and then the roller seat 2 is pushed into the receiving cavity 1111 (in this operation, the locking block 23 is also inserted into the first locking groove 112); then, the roller seat 2 is installed and fixed on the first clamping plate 11 by fasteners, and the first protrusion 111 is inserted into the preset installation opening of the bathroom door 5 from the front (at this time, the first clamping plate 11 abuts against the front side of the bathroom door 5), and the second clamping plate 12 is clamped on the bathroom door 5 from the rear side, so that the locking block 23 is also inserted into the second locking groove 121; then, the second clamping plate 12 and the first clamping plate 11 are clamped and fixed by screws and fasteners, so that the bathroom door 5 is clamped and fixed between the second clamping plate 12 and the first clamping plate 11.

[0057] like Figures 2 to 3 , Figures 6 to 8 As shown, specifically, the upper side of the first clamping plate 11 is provided with a first mounting hole 113, which is located near the end of the first clamping plate 11; the left and right ends of the roller seat 2 are provided with second mounting holes 24, which correspond to the first mounting holes 113 and are both arranged in the vertical direction; the first clamping plate 11 is fixedly connected to the roller seat 2 after passing through the first mounting hole 113 and the second mounting hole 24 with fasteners.

[0058] By providing the first mounting hole 113 and the second mounting hole 24, fasteners can be used to pass through the first mounting hole 113 and the second mounting hole 24 to fix the first clamping plate 11 and the roller seat 2 together, thereby preventing the first clamping plate 11 and the roller seat 2 from shifting back and forth, and making the connection between the first clamping plate 11 and the roller seat 2 more stable.

[0059] like Figures 4 to 6 , Figure 12 As shown, preferably, the middle part of the limiting cover plate 4 is provided with a receiving groove 42, and the front end of the receiving groove 42 is open; the upper side of the first clamping plate 11 is connected to a column 114, the column 114 passes through the receiving groove 42 and protrudes upward; the front end of the column 114 is provided with a limiting groove 1141, the limiting groove 1141 is recessed backward, and the length direction of the limiting groove 1141 is parallel to the vertical direction.

[0060] To further explain, in practical applications, a buffer 61 is connected inside the slide rail 6, and the buffer 61 is located near the end of the slide rail 6.

[0061] As the bathroom door 5 moves, the anti-jump bathroom door pulley moves along with the bathroom door 5. When the bathroom door 5 moves rapidly towards the end of the slide rail 6, the limiting groove 1141 allows the column 114 to abut against the buffer 61 through the limiting groove 1141 (e.g., Figure 16 As shown in the diagram, the buffer 61 can cushion the column 114, and since the roller 3 moves synchronously with the column 114, the roller 3 is also cushioned, making it less likely to spread out and further preventing it from jumping. Furthermore, by providing the receiving groove 42 on the limiting cover plate 4, the column 114 can pass through the cover plate 4, making the installation structure of the cover plate 4 and the column 114 compatible.

[0062] like Figure 6 and Figure 9 As shown, specifically, the first boss 111 has third mounting holes 115 at both its left and right ends, and the second clamping plate 12 has fourth mounting holes 122 at both its left and right ends. The fourth mounting holes 122 correspond to the third mounting holes 115 and are both arranged in the front-back direction.

[0063] By providing the third mounting hole 115 and the fourth mounting hole 122, screws and fasteners can be passed through the third mounting hole 115 and the fourth mounting hole 122 to fix the first clamping plate 11 and the second clamping plate 12 together, thus ensuring a stable connection between the first clamping plate 11 and the second clamping plate 12. Furthermore, because the third mounting hole 115 is located at both ends of the first boss 111, and the position of the first boss 111 corresponds to the preset mounting opening of the bathroom door 5, the installation position of the third mounting hole 115 can avoid the glass of the bathroom door 5, thereby avoiding drilling holes in the glass of the bathroom door 5.

[0064] like Figures 9 to 11 , Figure 17 As shown, preferably, the clamping assembly 1 further includes a first rubber pad 13 and a second rubber pad 14. The front and rear sides of the first rubber pad 13 are respectively connected to the first clamping plate 11 and the bathroom door 5. The rear part of the first rubber pad 13 is provided with a second boss 131 protruding rearward. The shape of the second boss 131 matches the shape of the first boss 111.

[0065] The front and rear sides of the second rubber pad 14 are respectively connected to the bathroom door 5 and the second clamping plate 12, and the shape of the second rubber pad 14 matches the shape of the second clamping plate 12.

[0066] In practical applications, the bathroom door 5 is typically a glass door, and it is clamped and fixed between the first clamping plate 11 and the second clamping plate 12. Without the first rubber gasket 13 and the second rubber gasket 14, the bathroom door 5 could crack if the first clamping plate 11 and the second clamping plate 12 are installed too tightly. However, by providing the first rubber gasket 13 and the second rubber gasket 14, they can be connected to the front and rear sides of the bathroom door 5 respectively (e.g., ...). Figure 17 As shown in the figure, the elasticity of the first rubber pad 13 and the second rubber pad 14 is used to buffer the impact, effectively preventing the bathroom door 5 from being cracked when the first clamping plate 11 and the second clamping plate 12 are installed too tightly.

[0067] Preferably, the first adhesive pad 13 and the second adhesive pad 14 are made of rubber or silicone.

[0068] like Figures 2 to 5 As shown, specifically, the rear part of the limiting cover plate 4 is provided with a fifth mounting hole 43, which penetrates the limiting cover plate 4 in the vertical direction and corresponds to the slide bar 41; the locking block 23 is provided with a sixth mounting hole 25, which is arranged in the vertical direction and communicates with the sliding groove 22, and corresponds to the fifth mounting hole 43; the limiting cover plate 4 is fixedly connected to the locking block 23 after passing through the fifth mounting hole 43 and the sixth mounting hole 25 with screw fasteners.

[0069] By setting the fifth mounting hole 43 and the sixth mounting hole 25, screws and fasteners can be passed through the fifth mounting hole 43 and the sixth mounting hole 25 and tightened to install and fix the limiting cover plate 4 on the card block 23, thereby preventing the limiting cover plate 4 from sliding out and causing its anti-jumping function to fail, and effectively improving the stability of the overall structure installation.

[0070] To further explain, the slide bar 41 is provided with an avoidance opening corresponding to the fifth mounting hole 43, so that the screw fastener can pass through the fifth mounting hole 43 through the limiting cover plate 4 and be inserted into the sixth mounting hole 25, thereby fixing the limiting cover plate 4 and the locking block 23.

[0071] like Figure 4 and Figure 17 As shown, preferably, the top surface of the front part of the limiting cover plate 4 is provided with an inclined surface 44, which is inclined downward.

[0072] By setting the inclined surface 44 downward on the top surface of the front part of the limiting cover plate 4, the front part of the limiting cover plate 4 can be smoothly inserted into the slide rail 6 when the limiting cover plate 4 is installed, thus improving the convenience of installation.
