Description

Technical Field

[0001] This invention relates to the field of borosilicate glass technology, and in particular to a borosilicate glass assembly that is easy to disassemble and clean. Background Technology

[0002] High borosilicate glass, due to its extremely low coefficient of thermal expansion, high temperature resistance, high hardness, and high chemical stability, has been widely used in high-end daily drinking water containers. However, during long-term use, the rounded corners of the inner bottom of traditional one-piece molded glass cups often become cleaning dead zones, easily accumulating tea stains, grease, or bacterial residues. Furthermore, due to the limited depth of the cup, ordinary cleaning tools cannot thoroughly reach these areas and apply sufficient mechanical friction, thus posing hygiene risks. Summary of the Invention

[0003] The present invention aims to solve the above-mentioned technical problems by providing an easy-to-disassemble and clean high borosilicate glass cup assembly.

[0004] The technical solution of this invention is an easily disassembled and cleaned high borosilicate glass cup assembly, comprising a cylindrical cup body, wherein the cylindrical cup body is a cylindrical structure with open ends, and an annular mounting groove is provided on the inner circumferential wall of its lower end. A composite elastic sealing ring is tightly fitted in the annular mounting groove. The composite elastic sealing ring forms a U-shaped cross section after being compressed to form a circumferential locking channel. An annular axial sealing flange is provided on the top surface of the composite elastic sealing ring. The assembly also includes a tightening component, which is inserted through the top opening of the cylindrical cup body. The component includes a tightening bearing plate spanning the interior of the cylindrical cup body. An anti-rotation limiting member is provided between the cylindrical cup body and the tightening bearing plate to prevent relative circumferential rotation between the two. The tightening bearing plate is provided with guide slides distributed radially thereon. A radial slider is slidably connected in the guide slides. The end of the radial slider is provided with a... The system includes a locking protrusion pressed into the locking groove, a drive pin connected to the radial slider that penetrates the cylindrical cup body downwards, and a cam-shaped driven head at the end of the drive pin; it also includes a base assembly that abuts against the bottom of the cylindrical cup body, and a rotary drive disk with a paddle rotatably connected to the base assembly. The rotary drive disk has spatial spiral grooves corresponding to the number of driven heads, and the starting end of the spatial spiral grooves has locking guide holes for the driven heads to enter axially; wherein, the rotary drive disk cooperates with the driven heads through the spatial spiral grooves to drive the radial slider to expand outwards along the guide slide during rotation, thereby achieving radial positioning of the locking protrusion and the locking groove, and simultaneously pulling the expansion bearing disk downwards to axially press the axial sealing flange through the drive pin.

[0005] In one embodiment, the cylindrical cup body is made of high borosilicate glass, and the wall thickness of the cylindrical cup body remains uniform throughout the circumference.

[0006] In one embodiment, the composite elastic sealing ring is made of either silicone or fluororubber.

[0007] In one embodiment, the cross-sectional shape of the locking protrusion is trapezoidal.

[0008] In one embodiment, the number of radial sliders is four, and all the radial sliders are evenly distributed around the central axis of the expansion bearing plate.

[0009] In one embodiment, the guide slide has a T-shaped cross-section, and the radial slider is slidably embedded in the guide slide through a corresponding T-shaped protrusion.

[0010] In one embodiment, the paddle is located at the edge of the rotating drive disk and is integrally formed with the rotating drive disk.

[0011] In one embodiment, the bottom of the base assembly is further provided with an anti-slip pad layer, which is fixed to the support surface of the base assembly by adhesive backing.

[0012] In one embodiment, the outer peripheral wall of the cylindrical cup is provided with a heat-insulating protective layer.

[0013] In one embodiment, the heat-insulating protective layer is made of leather, silicone sleeve, or cork.

[0014] The advantages of this invention compared to existing technologies are that the easily disassembled and cleanable high borosilicate glass cup assembly provided by this invention adopts a cylindrical cup body structure with open ends. After the locking state is released, the cup body presents a completely transparent tubular shape, allowing users to perform unobstructed through-cleaning with cleaning tools, fundamentally eliminating hygiene hazards. Furthermore, a composite elastic sealing ring is used as an intermediate medium to convert the locking force of the radial slider into uniform pressure from surface contact, effectively buffering the damage to the glass edges caused by mechanical impacts and thermal shocks. The linkage characteristics of the spatial spiral groove are also utilized to simultaneously achieve radial forced limiting and axial vertical clamping through a single rotation. The radial slider is embedded in the U-shaped locking groove to prevent the base from detaching when the cup body is filled with high-temperature liquids and internal pressure is generated. The driving expansion bearing plate vertically presses down on the sealing flange, forming a reliable airtight seal. Attached Figure Description

[0017] The above and other embodiments and advantages of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] In one implementation, such as Figures 1 to 5 As shown.

[0019] The easily disassembled and cleanable high borosilicate glass cup assembly provided in this embodiment includes a cylindrical cup body 1, which is a cylindrical structure with open ends. An annular mounting groove 2 is provided on the inner circumferential wall of its lower end. A composite elastic sealing ring 3 is tightly fitted within the annular mounting groove 2. When compressed, the composite elastic sealing ring 3 forms a U-shaped cross-section to create a circumferential locking channel 4. An annular axial sealing flange 5 is provided on the top surface of the composite elastic sealing ring 3. The assembly also includes a tightening component 6, which is inserted through the top opening of the cylindrical cup body 1. The component includes a tightening support plate 7 spanning the interior of the cylindrical cup body 1. An anti-rotation limiting member (not shown in the figure) is provided between the cylindrical cup body 1 and the tightening support plate 7 to prevent relative circumferential rotation between them. A guide slide 8 is provided on the tightening support plate 7, distributed radially. A radial slider 9 is slidably connected within the guide slide 8. The end of the radial slider 9 is provided with a lock that can be pressed into the locking channel 4. The device includes a locking protrusion 10, a radial slider 9 connected to a drive pin 11 that penetrates the cylindrical cup body 1 downwards, and a cam-shaped driven head 12 at the end of the drive pin 11; it also includes a base assembly 13, which abuts against the bottom end of the cylindrical cup body 1, and a rotating drive disk 15 with a paddle 14 rotatably connected to the base assembly 13. The rotating drive disk 15 has spatial spiral grooves 16 corresponding to the number of driven heads 12, and the starting end of the spatial spiral grooves 16 has a locking guide hole 17 for the driven heads 12 to enter axially; wherein, the rotating drive disk 15 cooperates with the driven heads 12 through the spatial spiral grooves 16, so as to drive the radial slider 9 to expand outwards along the guide slide 8 during rotation to achieve radial positioning of the locking protrusion 10 and the locking groove 4, and simultaneously pull the expansion bearing disk 7 downwards to axially press the axial sealing flange 5 through the drive pin 11.

[0020] In this embodiment, the anti-rotation limiting component can be a vertical rib on the inner wall of the glass and a groove on the edge of the expansion bearing plate 7, which cooperate to prevent relative circumferential rotation. The spatial spiral groove 16 is a three-dimensional curved cam groove. The bottom surface of the spatial spiral groove 16 is an inclined structure, and its depth gradually increases with the spiral path, thereby generating axial tension while driving the driven head 12 to move radially. In the assembled state, the user first pre-installs the elastic sealing sleeve in the annular mounting groove 2 at the lower end of the cylindrical cup body 1. Subsequently, the locking process is divided into three stages. First, the alignment stage, the user inserts the expansion assembly 6 from the top opening of the cup body, so that the driven head 12 at the bottom passes through the lower opening of the cup body and is inserted into the locking guide hole 17 of the rotating drive plate 15 in the base assembly 13. At this time, the edge of the expansion bearing plate 7 lightly touches the top surface of the axial sealing flange 5. Second, the radial locking stage, the user manually moves the lever 14 of the rotating drive plate 15. As the drive plate rotates, the driven head 12 enters the spatial spiral groove 16. Because the spiral groove has an outward diverging helix angle in its horizontal projection, it forces the drive pin 11 and its connected radial slider 9 to slide outward in a straight line along the guide slide 8. The locking protrusion 10 at the end of the radial slider 9 is gradually pressed into the U-shaped groove of the sealing sleeve, so that the expansion assembly 6 and the cup body form an initial limit. Third, in the axial compression stage, the radial locking occurs simultaneously, mainly in the latter half of the radial locking stage. As the lever 14 continues to rotate to the locked position, the axial depth of the spatial spiral groove 16 gradually increases. This change generates a downward pulling force through the drive pin 11, pulling the entire expansion bearing plate 7 vertically downward. At this time, the bottom surface of the bearing plate deeply compresses the axial sealing flange 5, the sealing ring undergoes elastic deformation and fills the tiny gap between it and the glass, and finally achieves airtight sealing. The unlocking process is the reverse of the locking process. By turning the lever 14 in the opposite direction, the driven head 12 retracts along the spatial spiral groove 16. As the spiral groove depth becomes shallower, the axial pulling force disappears, and the sealing flange rebounds upward by its own elasticity, lifting the expansion bearing plate 7. The composite elastic sealing ring 3 has a preset inward rebound prestress to drive the radial slider 9 to return to the axial direction after the locking protrusion 10 releases pressure. When the driven head 12 retracts to the starting end of the spiral groove, i.e., the position of the locking inlet hole 17, the radial slider 9 is no longer restricted by external force. By manually lifting, the locking protrusion 10 disengages from the U-shaped groove. At this time, the tensioning assembly 6 can be removed from the top as a whole, and the base assembly 13 detaches from the bottom. Since the cylindrical cup body 1 is a tube with open ends, users can use a brush to clean it without obstruction, thoroughly solving the problem of tea stains, grease, or bacterial residue accumulating at the corners of the traditional cup bottom.

[0021] In this embodiment, the innovation of the easily disassembled and cleaned high borosilicate glass cup assembly lies not only in the synchronous radial expansion and axial compression, but also in the use of the locking groove 4 as a mechanical conversion medium to transform rigid mechanical expansion into a non-destructive encapsulation and sealing of the glass, because high borosilicate glass cannot withstand high-precision thread processing and is prone to cracking.

[0022] In one embodiment, the easily disassembled and cleaned high borosilicate glass cup assembly provided in this embodiment has a cylindrical cup body 1 made of high borosilicate glass, and the wall thickness of the cylindrical cup body 1 remains uniform throughout the circumferential direction.

[0023] In this embodiment, the high borosilicate glass has excellent thermal stability. Combined with the uniform wall thickness design, it can ensure that when subjected to radial pressure generated by the expansion component 6 and thermal stress generated by the hot water, the stress can be evenly distributed on the cup wall, avoiding glass cracking caused by local stress concentration and improving the overall structural safety of the component.

[0024] In one embodiment, the easily disassembled and cleaned high borosilicate glass cup assembly provided in this embodiment has a composite elastic sealing ring 3 made of either silicone or fluororubber.

[0025] In this embodiment, a material with high elasticity and chemical resistance is selected to ensure that the sealing ring can produce stable deformation and have good elastic recovery force under repeated pressure from the expansion slider. When the locking state is released, the sealing ring can quickly disengage from the locking protrusion 10 using its own elasticity, facilitating the rapid sliding out and disassembly of the component.

[0026] In one embodiment, the easily disassembled and cleaned high borosilicate glass cup assembly provided in this embodiment has a trapezoidal cross-sectional shape for its locking protrusion 10.

[0027] In this embodiment, the trapezoidal cross section has a certain wedge-shaped self-locking effect when pressed into the U-shaped locking groove 4, which can increase the contact area of ​​radial locking, make the locking process more stable, and provide higher radial resistance to disengagement in the fully locked state.

[0028] In one embodiment, the easily disassembled and cleaned high borosilicate glass cup assembly provided in this embodiment has four radial sliders 9, and all the radial sliders 9 are evenly distributed around the central axis of the expansion bearing plate 7.

[0029] In this embodiment, four sliders are arranged in a cross shape, which can make the tensioning force symmetrically distributed on the inner circumference of the glass cup, preventing the tensioning bearing plate 7 from tilting or getting stuck during the force process, and ensuring the uniformity of axial sealing pressure.

[0030] In one embodiment, the easily disassembled and cleaned high borosilicate glass cup assembly provided in this embodiment has a T-shaped cross-section of the guide slide 8, and the radial slider 9 is slidably embedded in the guide slide 8 through a corresponding T-shaped protrusion.

[0031] In this embodiment, the T-shaped structure provides an effective vertical constraint, limiting the radial slider 9 from wobbling up and down when subjected to complex stress transmitted by the driven head 12, ensuring that the slider can only make linear reciprocating motion in the radial direction, thereby improving the accuracy and durability of the transmission structure.

[0032] In one embodiment, the easily disassembled and cleaned high borosilicate glass cup assembly provided in this embodiment has a paddle 14 disposed at the edge of the rotating drive disk 15 and integrally formed with the rotating drive disk 15.

[0033] In this embodiment, the one-piece molding increases the mechanical strength of the lever 14, enabling it to withstand the torque required to drive the spiral groove 16. The edge design facilitates the user to apply force on the outside of the cup body, optimizing the operating lever arm and making the locking and unlocking process more effortless.

[0034] In one embodiment, the easily detachable and cleanable high borosilicate glass cup assembly provided in this embodiment also has an anti-slip pad layer 18 at the bottom of its base assembly 13, and the anti-slip pad layer 18 is fixed to the support surface of the base assembly 13 by adhesive backing.

[0035] In this embodiment, the anti-slip pad 18 increases the coefficient of friction between the base and the supporting plane, and provides auxiliary anti-torsional resistance when the rotating lever 14 is used for locking, while also protecting the base and reducing shock.

[0036] In one embodiment, the easily disassembled and cleaned high borosilicate glass cup assembly provided in this embodiment has a heat-insulating protective layer 19 on the outer peripheral wall of its cylindrical cup body 1.

[0037] In this embodiment, the heat insulation layer 19 can effectively block the heat conduction from the high-temperature liquid inside the borosilicate glass cup to the outer wall, reduce the temperature rise rate of the cup surface, and provide a safe gripping area for the user.

[0038] In one embodiment, the easily disassembled and cleaned high borosilicate glass cup assembly provided in this embodiment has a heat-insulating protective layer 19 made of leather, silicone sleeve, or cork.

[0039] In this embodiment, these materials have low thermal conductivity and provide a good non-slip feel, further enhancing the practicality of the glass assembly in high-temperature use scenarios.

[0040] The specific embodiments described above further illustrate the inventive purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the scope of protection of the present invention. In particular, it should be noted that any modifications, equivalent substitutions, or improvements made by those skilled in the art within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
