Description

Fixed pipe fittings and their mounting bases FIXED ROD ASSEMBLY AND BRACKET THEREOF Technical Field

[0001] This work relates to a fixing device, and in particular to a fixing pipe fitting device and its fixing seat. Prior Technology

[0002] Existing pipe fixing devices, when used in bathrooms, kitchens or outdoor environments, are prone to moisture and liquid seeping into the fixing base or the gaps in contact with the wall, leading to internal corrosion, structural loosening, and even shortening of service life.

[0003] Furthermore, traditional pipe fixing brackets often suffer from insufficient structural strength when subjected to external forces or prolonged use, leading to pipe swaying or unstable fixation, which affects the user experience. Therefore, it is necessary to provide a fixed pipe fitting device and its fixing bracket to improve waterproofing and durability, and ensure stable fixing of the pipe fitting. Summary of the Invention

[0004] According to a preferred embodiment, the present invention provides a fixed pipe fitting device and a fixing base. The fixed pipe fitting device includes a fixing base and a pipe fitting, wherein the pipe fitting is connected in series on the fixing base. The fixing base includes a base and a top cover that are substantially coaxially fitted onto the base, wherein the top cover is higher than the base.

[0005] In one embodiment of this invention, the base includes a hollow small cylinder and a base plate surrounding the hollow small cylinder, and the upper cover includes a hollow large cylinder and an outwardly expanding bottom frame surrounding the hollow large cylinder and covering the base plate. The base plate has an outer diameter, and the outwardly expanding bottom frame has an inner diameter. The hollow small cylinder has a first wall thickness, and the hollow large cylinder has a second wall thickness.

[0006] In one embodiment of this invention, the extended bottom frame is higher than the base plate.

[0007] In one embodiment of this invention, the base includes an umbrella-shaped skirt that surrounds the hollow large cylinder.

[0008] In one embodiment of this invention, both the extended bottom frame and the base plate are square.

[0009] In one embodiment of this invention, the outer diameter of the base plate is smaller than the inner diameter of the outwardly expanding base frame.

[0010] In one embodiment of this invention, the second wall thickness of the large hollow cylinder is approximately 1.5 times the first wall thickness of the small hollow cylinder.

[0011] In one embodiment of this invention, the base plate includes a plurality of circular holes.

[0012] In one embodiment of this invention, the holes are three holes that are equidistant from each other.

[0013] By installing a base and a top cover that extends above the base on the mounting bracket, the top cover not only substantially covers the base but also forms an external protective barrier, effectively preventing external moisture or liquid from seeping in and improving waterproofing and weather resistance. The increased height or thickness of the top cover makes the overall structure of the mounting bracket more stable, able to withstand greater external forces without easily deforming or loosening. Furthermore, the combination of the extended base frame and the base plate provides excellent fixing strength and ease of installation, making it widely applicable in bathrooms, kitchens, or other high-humidity environments requiring long-term fixation.

[0022] The following diagrams will disclose several embodiments of this invention. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this invention. That is, these practical details are not essential in the embodiments of this invention. In addition, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the diagrams.

[0023] It will be understood that although specific terms such as "first," "second," and "third" are used in the text to describe different elements, spaces, or areas, these elements, spaces, or areas should not be limited to these terms. These terms are used to distinguish one element, space, or area from another. Thus, a first element, space, or area described below may be referred to as a second element, space, or area, or a third element, space, or area, without departing from the spirit and scope of this work.

[0024] Spatial relative terms, such as "above," "below," "inside," "outside," "between," "to the left," "to the right," and "to the left and right of," are used in the text to easily describe the relationship between one element or feature and another shown in the diagram. Therefore, it can be understood that, in addition to the orientation depicted in the diagram, spatial relative terms encompass different orientations when the device is used or operated. For example, if the device in the diagram is flipped (e.g., but not limited to, rotated 180 degrees), the element described as "to the left" of other elements or features will be oriented "to the right" of other elements or features. Similarly, if the device in the diagram is flipped (e.g., but not limited to, rotated 180 degrees), the element described as "above" of other elements or features will be oriented "below" of other elements or features. Therefore, the exemplary terms "on" (or "on") may include both above and below. The device may be otherwise oriented (e.g., rotated 180 degrees, 90 degrees, or otherwise), and the spatial relative terms used in the text should be interpreted accordingly.

[0025] Therefore, when a component is referred to as being "on," "connected," "connected in series," "joined," "set on," "connected to," or "linked" to another component, it can be directly on or linked to the other component, or there may be one or more intermediate components or intermediate layers. Furthermore, when a component is referred to as being "between" two components, it can be the only component or layer between the two components, or there may be one or more intermediate components or intermediate layers.

[0026] The use of spatial relative terms in the patent specification is for the purpose of readily describing the relationship between one element and another element or feature depicted in the figures. Therefore, it can be understood that, in addition to the orientation depicted for a particular element in the figure (e.g., the back of the base), spatial relative terms encompass different orientations during the use or operation of the device. For example, if the base in the figure is flipped (e.g., but not limited to a 90-degree rotation), the back of the base will be referred to as the "side of the base." Similarly, if the base in the figure is flipped (e.g., but not limited to a 180-degree rotation), the back of the base will be referred to as the "front of the base," and vice versa. Thus, the back or front of the base can be otherwise oriented (e.g., rotated 180 degrees, 90 degrees, or, for example, in other orientations), and the spatial relative terms used herein should be interpreted accordingly.

[0027] The relative terms of space, such as "above" as used in this text, are used to easily describe the positional relationship between one element and another in a diagram. Therefore, it can be understood that, in addition to the orientation depicted in the diagram (above), the relative terms of space encompass different orientations when the device is used or operated. For example, if the upper element in the diagram is flipped (e.g., but not limited to rotating 180 degrees), the element described as "above" will be renamed the "lower" element. Conversely, the upper element can be repositioned (e.g., rotated 180 degrees or, for example, in other orientations), and the relative terms of space used in this text should be interpreted accordingly.

[0028] In the description of this work, it should be noted that, unless otherwise explicitly stated, the terms "connected," "series," "series on," "fitted on," "surrounded by," "surrounded by," "covered," "adjacent to," "set on," "set in," "through," "locked in," "cover," "hide," "connect," "receive," "connected to," "inserted in," "at," "placed in," and "connected" should be interpreted broadly. For example, "connected to" can also refer to a detachable connection, a fixed connection, a one-piece connection, a mechanical connection, an electrical connection, a direct connection, an indirect connection through an intermediate medium, a connection within two components, or an indirect rotatable connection through an intermediate medium. Those skilled in the art will understand the specific meaning of the above terms in this work based on the specific circumstances.

[0029] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms "a" and "the" used herein also include the plural forms unless the context clearly indicates otherwise. It is thus understood that when words such as "comprising" are used in the specification, they explicitly state the presence of a specified feature, integral, step, operation, element, and / or component, but do not preclude the presence or addition of one or more features, integrals, steps, operations, elements, components, and / or groups thereof. The term "and / or" used herein includes any and all combinations of one or more related listed terms. When a list of elements is preceded by a phrase such as "at least one of...", it modifies the entire list of elements, not the individual elements listed.

[0030] Figure 1 illustrates a schematic diagram of a fixed rod assembly according to a first preferred embodiment of the present invention. Referring to Figure 1, the fixed rod assembly may include two brackets 100l and 100r and a straight rod 10. The brackets 100l and 100r may include a left bracket 100l and a right bracket 100r, wherein the straight rod 10 is connected between the left bracket 100l and the right bracket 100r.

[0031] Figure 2 illustrates a schematic diagram of another fixed pipe fitting device according to a second preferred embodiment of the present invention. Referring to Figure 2, the fixed pipe fitting device may include two fixing seats 100l and 100r, and a bent rod 20. The fixing seats 100l and 100r include a left fixing seat 100l and a right fixing seat 100r, wherein the bent rod 20 is connected in series with the left fixing seat 100l and the right fixing seat 100r.

[0032] Figure 3 illustrates an exploded view of a mounting base according to a third preferred embodiment of the present invention. Referring to Figure 3, the mounting base may include a base 200a and a cover 100a that can be substantially coaxially sleeved on the base 200a. The base 200a may be an iron base. The cover 100a may be a zinc alloy cover. The height of the cover 100a may be similar to the height of the base 200a to facilitate coaxial sleeved engagement. Preferably, the cover 100a is slightly higher than the base 200a, for example, by about 3-10%, preferably about 5.6%. The height 494a of the cover 100a is, for example, about 30-70 mm, preferably about 41.2 mm, and the height 460a of the base 200a is, for example, about 25-65 mm, preferably about 39.0 mm.

[0033] The base 200a may include a hollow small cylinder 210a and a base plate 220a surrounding the hollow small cylinder 210a. The hollow small cylinder 210a may have a first wall thickness 450a. The top cover 100a may include a hollow large cylinder 110a and an outwardly expanding bottom frame 120a surrounding the hollow large cylinder 110a and covering the base plate 220a. The hollow large cylinder 110a may have a second wall thickness 493a. The base plate 220a may have an outer diameter 410a. The outwardly expanding bottom frame 120a may have an inner diameter 482a.

[0034] The hollow small cylinder 210a is substantially slightly smaller than the hollow large cylinder 110a to form a space that facilitates coaxial fitting. More specifically, the hollow large cylinder 110a has an outer diameter 491a and an inner diameter 492a, and the hollow small cylinder 210a has an outer diameter 430a. The outer diameter 430a of the hollow small cylinder 210a is substantially smaller than the inner diameter 492a of the hollow large cylinder 110a, thus forming a space that facilitates coaxial fitting. The hollow small cylinder 210a may have an inner diameter 440a. Because the outer diameter 430a of the hollow small cylinder 210a is substantially smaller than the inner diameter 492a of the hollow large cylinder 110a, the resulting space is very small, just enough to form a "tight" fit, or just enough to accommodate an O-ring seal.

[0035] The hollow large cylinder 110a has a second wall thickness of 493a, and the hollow small cylinder 210a has a first wall thickness of 450a. The second wall thickness 493a of the hollow large cylinder 110a is approximately 1.2-3 times, preferably approximately 1.5 times, the first wall thickness 450a of the hollow small cylinder 210a.

[0036] The expanded bottom frame 120a is substantially slightly larger and slightly higher than the base plate 220a, which provides a covering effect to prevent water droplets from seeping in and creates a space for coaxial fitting. More specifically, the expanded bottom frame 120a has an outer diameter 480a and an inner diameter 482a, and the base plate 220a has an outer diameter 410a. The inner diameter 482a of the expanded bottom frame 120a is substantially larger than the outer diameter 410a of the base plate 220a to create a space for coaxial fitting.

[0037] The hollow small cylinder 210a of the base 200a may have a pin hole 282 for inserting a positioning pin to fix a straight pipe 10 (Fig. 1) or a bent pipe 20 (Fig. 2), or to prevent the straight pipe 10 or the bent pipe 20 from rotating.

[0038] Referring to Figure 3, the hollow large cylinder 110a of this invention may include a front sidewall 110f and a rear sidewall 110r connected to the front sidewall 110f. The hollow large cylinder 110a may include at least one fixing screw hole 302f with a diameter of approximately 4 mm. After coaxial fitting, this hole can be used to ensure that the fitting position of the upper cover 100a and the base 200a is fixed and does not rotate. The hollow large cylinder 110a may include two fixing screw holes 302f, one purpose of which is to allow screws to be tightened during installation to secure the upper cover 100a to the hollow small cylinder 210a inside the pipe fitting (e.g., the straight pipe fitting 10 in Figure 1 or the bent pipe fitting 20 in Figure 2), preventing rotation or loosening.

[0039] When the fitting is inserted into the hollow cylinder 110a of the top cover 100a, if it is only fixed by friction, it may loosen after long-term use. The two fixing screw holes 302f can be used to lock in stop screws or positioning screws, directly pressing against the outer wall of the fitting to form a point contact fixation, preventing the fitting from slipping or rotating due to external forces (such as hanging heavy objects or pulling). In addition, the two fixing screw holes 302f can distribute the installation force, making the connection between the fitting and the top cover 100a more secure. Even in high-humidity environments such as bathrooms, the screw locking maintains stability, preventing loosening due to thermal expansion and contraction or humidity changes. Furthermore, if the fitting is damaged, it can be replaced simply by loosening the screws, without the need for complete disassembly, resulting in low maintenance costs. Moreover, compared to welding, the locking mechanism using these two fixing screw holes 302f avoids heat-induced deformation caused by welding points, resulting in a more refined structure.

[0040] Figure 4 illustrates a bottom view of a base plate according to a third preferred embodiment of the present invention. Referring to Figure 4, the base plate may include three circular holes 300a and at least one elongated slot 310, for example, two elongated slots 310. The elongated slots 310 may be substantially parallel to each other. The circular holes 300a may be substantially equidistant from each other. The diameter 402a of the circular holes 300a may be, for example, about 4.5 mm, the length 312a of the elongated slots 310a may be, for example, about 10 mm, and the width 314a may be, for example, about 4.5 mm. The three equidistantly spaced circular holes 300a enable the fixing rivets or screws 103 (Figure 1 or Figure 2) or rivets to be evenly distributed during installation, avoiding excessive force on one side that could cause deformation or loosening of the base. The 300a layout of equidistant circular holes can also create balanced tension on the wall or other mounting surfaces, enhancing load-bearing capacity, making it particularly suitable for supporting components that require stability, such as shower curtain rods or handrails.

[0041] The design of these elongated holes 310a allows installers to make fine adjustments along the length 312a (approximately 10 mm) when fixing the screws. This fine-tuning function overcomes errors during wall drilling or when encountering internal wall structures (such as solid wood strips or steel bars), ensuring a suitable fixing point is found. Therefore, these elongated holes 310a provide a wider range of installation tolerance, improving the convenience and efficiency of on-site construction. Furthermore, the combined configuration of round holes 300a and elongated holes 310a provides both fixed positioning and flexible adjustment. When installing on tile, concrete, or wooden walls, the round holes 300a can be used for primary positioning, and then the elongated holes 310a can be used for correction, ensuring a tight fit against the wall without gaps. Moreover, when the screw 103 (Figure 1 or Figure 2) is tightened into these round holes 300a, the even and stable force distribution reduces the likelihood of water seepage due to loosening around the screw 103. These elongated holes (310a) allow for installation in locations that avoid cracks or water lines on the wall, preventing damage to the waterproofing layer. This configuration is particularly advantageous in high-humidity bathrooms or outdoor environments. Furthermore, the round holes (402a) and elongated holes (314a) all use a uniform specification of approximately 4.5 mm, making them compatible with commonly available screw sizes. This reduces the complexity of mold design for manufacturing and eliminates the need for specialized screws for installation, lowering overall installation costs.

[0042] Figure 5 illustrates a bottom schematic diagram of an expanded bottom frame according to a third preferred embodiment of the present invention. Figure 6 illustrates a cross-sectional schematic diagram of an expanded bottom frame according to a third preferred embodiment of the present invention. Referring to Figures 5, 6, and 3, the expanded bottom frame 120a may include a front sidewall 120f and a rear sidewall 120r connecting the front sidewall 120f. The expanded bottom frame 120a may further include a front flange 122f located within the front sidewall 120f, and the expanded bottom frame 120a may further include a rear flange 122r located within the rear sidewall 120r. The front flange 122f and the rear flange 122r can disperse edge stress, which helps with zinc alloy demolding and prevents chipping, and also facilitates control of pipe dimensional tolerances. The front flange 122f and the rear flange 122r are substantially slightly higher than the base plate 220a (Figure 3), and are above but not adjacent to the base plate 220a, forming a labyrinth-type water-blocking path. This allows water or water vapor to encounter a second layer of obstruction even if it enters, causing the water pressure to gradually decrease and the flow rate to slow down. In addition, the capillary action is interrupted, thus preventing it from penetrating into the interior.

[0043] Referring to Figures 6 and 3, the height 420a of the base plate 220a can be approximately 1.5 mm. The height 496 of the outwardly flared base frame 120a can be approximately 6 mm. The thickness 490a of the outwardly flared base frame 120a can be approximately 1.5 mm. The thickness 484a of the rear flange 122r (Figure 5) or the front flange 122f can be approximately 2 mm.

[0044] Figure 7 illustrates a cross-sectional view of another top cover according to a fourth preferred embodiment of the present invention. Referring to Figure 7, in a fourth embodiment of the present invention, the top cover 100a may include a conical skirt portion 120b surrounding the hollow large cylinder 110a. The conical skirt portion 120b allows the top cover 100a to cover a larger area, concealing construction errors, screw holes, or wall imperfections. The conical skirt portion 120b includes an outward convex arc 132 and an inward concave arc 134 surrounding the outward convex arc 132 and the outwardly flared bottom frame 120a. The convex arc 132 and the concave arc 134 form a continuous curved surface, guiding water droplets outwards to the outer side of the wall, resulting in higher water resistance and significantly reducing water accumulation at the interface between the base 200a and the wall. The convex arc 132 and the concave arc 134 also reduce stress concentration, preventing cracks caused by external impacts or thermal expansion and contraction.

[0045] Figure 8 illustrates a fifth preferred embodiment of the present invention, showing another top cover and base. In this fifth embodiment, the top cover 100a includes a square outwardly expanding bottom frame 120c, and the base 200a includes a square base plate 220c. Compared to a circular outwardly expanding bottom frame or a circular base plate, the square outwardly expanding bottom frame 120c and the square base plate 220c have at least the following advantages:

[0046] Orientation and anti-rotation: The sides of the square, outwardly flared base frame 120c are aligned with the horizontal and vertical directions of the wall, providing a visual and installation reference, suppressing the spontaneous rotation of the top cover 100a after installation, and improving long-term positioning stability.

[0047] Corner shielding: The side length of the square outer frame 120c is 680c, for example, about 54 mm, which is slightly larger than the side length of the square base plate 220c, 610c, for example, about 50 mm, so that the four sides form a linear shielding band, which is better than the circle for covering the straight seams and corner gaps of the tiled wall.

[0048] Installation alignment: The base plate 220c includes a plurality of elongated holes 310a distributed parallel to the square boundary, allowing the installer to make fine adjustments in the horizontal or vertical direction, making alignment intuitive and reducing working time.

[0049] Although the present disclosure has described the embodiments as above, other embodiments are also possible. Therefore, the spirit and scope of the claims are not limited to the descriptions contained herein. Anyone skilled in the art will understand that various modifications and refinements can be made without departing from the spirit and scope of the present disclosure. Therefore, the scope of protection of the present disclosure shall be determined by the appended claims.
