[0012] This utility model also provides a mobile phone holder, which includes: The retaining structure for the replaceable suction cup as described above includes: The suction cup is made of soft plastic and has a recessed receiving chamber at the bottom. The suction cup hard plastic part is aligned with the center of the suction cup soft plastic part and connected to it as one piece.

[0034] The terms "first" and "second" in this utility model are used for descriptive purposes only and should not be construed as indicating or implying relative importance, nor as a restriction on the order of events.

[0035] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in Figure 1This is a schematic diagram of the overall structure of a mobile phone holder according to a preferred embodiment of the present invention. Figure 2 This is a cross-sectional view of the overall structure of the rear phone holder according to a preferred embodiment of the present invention. Figure 3 The fixed three-dimensional structure of the preferred embodiment of this utility model Figure 1 . Figure 4 This is an exploded view of the fixing structure of a preferred embodiment of the present invention.

[0036] The following is a preferred embodiment of a replaceable suction cup fixing structure and a corresponding mobile phone holder provided by this utility model, which can solve the above technical problems.

[0037] The preferred embodiment of the replaceable suction cup fixing structure and corresponding mobile phone holder provided by this utility model is as follows: A replaceable suction cup fixing structure includes a soft suction cup 1, a hard suction cup 2, a support 3, and a screw 4. The soft suction cup 1 is made of elastic rubber material, and its bottom end has a recessed receiving chamber 11, which is used to form a negative pressure adsorption with the adsorption surface. The hard suction cup 2 is aligned with the center of the soft suction cup 1 and connected as a whole. The hard suction cup 2 has a first connecting hole 21 penetrating through the upper and lower surfaces in the middle. The support 3 is disposed above the hard suction cup 2. The bottom end of the support 3 has a first threaded groove 31, and the top end is used to connect an external bracket. In this embodiment, the external bracket is used to support the mobile phone. The screw 4 penetrates the first connecting hole 21 of the hard suction cup 2 and is threadedly connected to the first threaded groove 31 of the support 3.

[0038] By combining "suction cup soft plastic part 1, suction cup hard plastic part 2, support part 3, and screw 4", a detachable connection between the suction cup assembly (suction cup soft plastic part 1 and suction cup hard plastic part 2) and the support part 3 is achieved. Compared with traditional integrated suction cups, when the suction cup soft plastic part 1 ages or wears, only screw 4 needs to be unscrewed to replace the suction cup assembly, without the need to replace the entire fixing device, which greatly reduces the cost of use and reduces resource waste. At the same time, the elastic rubber material of the suction cup soft plastic part 1 can ensure a tight fit with the suction surface, while the hard plastic part provides structural support. The two work together to balance suction and stability.

[0039] The following is a detailed description of the fixing structure of the replaceable suction cup in this embodiment: Combination Figure 2 and Figure 4 The fixing structure in this embodiment also includes a sealing ring 5, which seals the support member 3 and the suction cup hard plastic part 2. The sealing ring 5 fills the gap between the support member 3 and the suction cup hard plastic part 2, which can effectively prevent external air from entering the receiving chamber 11 of the suction cup soft plastic part 1, ensuring that the receiving chamber 11 can stably maintain a negative pressure state and avoid the decrease in adsorption force due to air leakage.

[0040] The structure of the suction cup hard plastic part 2 in this embodiment is described as follows: Combination Figure 2 , Figure 4 and Figure 5 The suction cup hard plastic part 2 has a first receiving groove 22 at its top, which is adapted to the bottom end of the support part 3. The bottom end of the support part 3 is connected to the first receiving groove 22. In this embodiment, it is preferred that the bottom end of the support part 3 is inserted into the first receiving groove 22. Other connection methods such as butt joint and adhesive bonding can also be used, which will not be described in detail here. The first receiving groove 22 provides a precise positioning reference for the support part 3, ensuring that the connection position between the support part 3 and the suction cup hard plastic part 2 is fixed, avoiding relative shaking or displacement between the two during use, and improving structural stability. At the same time, the insertion fit simplifies the assembly process and can be quickly installed without additional positioning tools.

[0041] Furthermore, a second receiving groove 23 is provided at the top of the suction cup hard plastic part 2. The second receiving groove 23 is located at the bottom of the first receiving groove 22 and is interconnected with it. The cross-sectional width of the second receiving groove 23 is smaller than that of the first receiving groove 22, and the sealing ring 5 is disposed in the second receiving groove 23. The bottom of the first receiving groove 22 is provided with a second receiving groove 23 that is connected to it. The cross-sectional width of the second receiving groove 23 is smaller than that of the first receiving groove 22, and it is used to install the sealing ring 5. The "stepped" design of the second receiving groove 23 (the cross-section is smaller than that of the first receiving groove 22) provides a dedicated installation space for the sealing ring 5, which can effectively limit the displacement of the sealing ring 5 and prevent it from falling off during assembly or use. At the same time, the stepped structure makes the bottom of the support 3 contact more tightly with the suction cup hard plastic part 2, and the sealing ring 5 is tightly squeezed, further enhancing the sealing effect and ensuring negative pressure stability.

[0042] The bottom end of the suction cup hard plastic part 2 extends to the bottom surface of the suction cup soft plastic part 1, preventing deformation at the center of the suction cup soft plastic part 1. The bottom end of the suction cup hard plastic part 2 is provided with a third receiving groove 24, which is used to receive the nut 41 of the screw 4. The third receiving groove 24 hides the nut 41 inside the suction cup hard plastic part 2, preventing the nut 41 from protruding from the bottom surface of the suction cup soft plastic part 1, ensuring the flatness of the suction cup soft plastic part 1 against the suction surface, and preventing sealing failure caused by the nut 41 protruding; at the same time, the hidden design protects the nut 41 from external impacts, friction, and other damage, extending the service life of the screw 4.

[0043] like Figure 4As shown, in this embodiment, a connecting plate 25 is provided on the outer side of the suction cup hard plastic part 2, and a fixing groove 15 is provided on the suction cup soft plastic part 1. The connecting plate 25 is fitted into the fixing groove 15. In this embodiment, the connecting plate 25 can be a triangular, rectangular, or other polygonal structure to further prevent relative wobbling between the suction cup hard plastic part 2 and the suction cup soft plastic part 1. The fitting of the connecting plate 25 and the fixing groove 15 significantly increases the contact area between the suction cup hard plastic part 2 and the suction cup soft plastic part 1, improves the connection strength between the two, and effectively prevents separation due to excessive pulling force during use. The polygonal connecting plate 25 can use its shape characteristics to restrict relative rotation, prevent relative sliding between the suction cup hard plastic part 2 and the suction cup soft plastic part 1, and further enhance structural stability.

[0044] Furthermore, the connecting plate 25 is provided with a second connecting hole 251, and the suction cup soft plastic part 1 is provided with a positioning post 16. The positioning post 16 is located in the fixing groove 15 and is inserted into the second connecting hole 251. In this embodiment, the connecting plate 25 is preferably circular. The insertion of the positioning post 16 into the second connecting hole 251 prevents the connecting plate 25 from rotating relative to the suction cup soft plastic part 1, thereby improving the connection stability between the suction cup hard plastic part 2 and the suction cup soft plastic part 1. The precise insertion of the positioning post 16 into the second connecting hole 251 achieves "dual positioning," further restricting the relative rotation of the two on the basis of fitting, ensuring that the central axis of the suction cup hard plastic part 2 and the suction cup soft plastic part 1 coincides, and avoiding uneven adsorption force caused by eccentricity; at the same time, this structure simplifies the alignment process during assembly and improves the efficiency during production or replacement.

[0045] In the fixing structure of this embodiment, the suction cup soft plastic part 1 is made of elastic rubber material, the suction cup hard plastic part 2 is made of hard plastic, and the suction cup hard plastic part 2 and the suction cup shaft 14 of the suction cup soft plastic part 1 are fixedly connected by injection molding.

[0046] The structure of the suction cup soft plastic part 1 in this embodiment is described below: Combination Figure 1 and Figure 2 The suction cup soft plastic component 1 includes a disc body 12, an annular abutment surface 13, and a suction cup shaft 14. The disc body 12 has a circular structure with a concave receiving chamber 11 on its bottom surface. The annular abutment surface 13 is located on the bottom surface of the disc body 12 and is situated around the receiving chamber 11, forming a seal with the adsorption surface. The suction cup shaft 14 is located at the center of the disc body 12 and is used to connect with the suction cup hard plastic component 2. Its outer side forms the receiving chamber 11 between the annular abutment surface 13 and the bottom surface of the disc body 12. As the core component for force transmission, the suction cup shaft 14 is directly connected to the suction cup hard plastic component 2. When the support component 3 is pulled, it can precisely drive the receiving chamber 11 to contract, ensuring stable negative pressure. The overall structure balances elastic deformation (facilitating adsorption) and rigid transmission (facilitating operation), improving the reliability of adsorption.

[0047] Combination Figure 1 and Figure 2 This embodiment also provides a mobile phone holder, which includes a fixing structure for the replaceable suction cup described in the above embodiment, a support base 6, a connecting rod component 7, and a panel 8. The support base 6 is connected to the top end of the support member 3; the connecting rod component 7 is disposed on the support base 6; the panel 8 is connected to the top end of the connecting rod component 7, and the panel 8 is used to support the mobile phone. The support base 6 is connected to the support member 3, and the support base 6 includes a fixed plate 61, a first rotating plate 62, a support plate 63, a second rotating plate 65, and a rotating shaft 64. The support member 3 is provided with a shaft hole 32; the fixed plate 61 is fixedly connected to the support member 3; the first rotating plate 62 is rotatably connected to the top end of the fixed plate 61, and the axes of the first rotating plate 62 and the fixed plate 61 are on the same straight line. The support plate 63 is disposed above the first rotating plate 62, and the support plate 63 is used to close the top end of the connecting cylinder 621. The second rotating plate 65 is rotatably positioned above the support plate 63. The second rotating plate 65 is connected to the bottom end of the connecting rod component 7. After the suction cup is lifted and fixed by the support component 3, the second rotating plate 65 can further adjust the orientation of the panel 8 without having to disassemble the suction cup again, thus improving the flexibility of use.

[0048] A connecting cylinder 621 is vertically mounted at the center of the first rotating plate 62. The connecting cylinder 621 is sleeved on the outside of the support member 3, and its inner wall is provided with a first guide groove 6211. Taking the plane where the bottom end of the connecting cylinder 621 is located as a reference, the distance from one end of the first guide groove 6211 in the extension direction to the plane gradually increases. A positioning groove 6212 is provided at one end of the first guide groove 6211 in the extension direction. The rotating shaft 64 is fixedly mounted in the shaft hole 32, and its end extends into the first guide groove 6211, which can slide along the first guide groove 6211 and engage with the positioning groove 6212.

[0049] In this embodiment, the rotating shaft 64 has an initial position and a fixed position along the movement direction of the first guide groove 6211. The fixed position is above the initial position, and the positioning groove 6212 is located in the fixed position. When the rotating shaft 64 is in the initial position, the suction cup soft plastic part 1 is equal to the external air pressure, and the fixed structure does not have an adsorption effect. When the rotating shaft 64 is in the fixed position, the rotating shaft 64 pulls the support 3 upward, and the support 3 drives the suction cup hard plastic part 2 and the suction cup shaft 14 part of the suction cup soft plastic part 1 to move upward, thereby creating a negative pressure in the receiving chamber 11 of the fixed structure, which adsorbs onto the adsorption surface.

[0050] The following describes the other structural features of the phone holder: Combination Figure 6 and Figure 7The top surface of the fixed plate 61 is provided with two symmetrically distributed guide posts 611, and the first rotating plate 62 is provided with a second guide groove 622 at the corresponding position. The guide posts 611 and the second guide groove 622 are slidably connected to improve the rotational stability of the first rotating plate 62. The cooperation between the guide posts 611 and the second guide groove 622 restricts the radial displacement of the first rotating plate 62, ensuring that it can only rotate around the center of the fixed plate 61, avoiding eccentric friction between the connecting cylinder 621 and the support member 3 during rotation, and reducing component wear; at the same time, the sliding cooperation can disperse the stress during rotation, preventing the connection between the fixed plate 61 and the first rotating plate 62 from breaking due to uneven stress, and extending the service life of the bracket.

[0051] Combination Figure 1 and Figure 8 In this embodiment, the connecting rod component 7 adopts a foldable storage structure, with its top end hinged to the panel 8 and its bottom end hinged to the support base 6. The folding design can significantly reduce the storage volume of the bracket, making it easy to carry; the hinged structure allows the connecting rod component 7 to finely adjust the height of the panel 8 after it is attached and fixed, making the structure highly adaptable.

[0052] Combination Figure 2 In this embodiment, the panel 8 has a magnetic suction piece 81 inside, which is used to magnetically attach and fix the mobile phone. The magnetic fixation method does not require buckles or claws, and the mobile phone can be quickly picked up and put on without causing squeezing damage to the mobile phone shell. In addition, this structural design can easily realize the switching between landscape and portrait screens of the mobile phone, and the operation efficiency is higher.

[0053] The structure of support member 3 in this embodiment is described below: like Figure 7 As shown, the support member 3 in this embodiment includes a base 33 and a square rod 34. The base 33 is inserted into the first receiving groove 22, and the bottom end of the base 33 is connected to the sealing ring 5. The connecting rod is vertically arranged on the base 33, and the fixing plate 61 is sleeved on the square rod 34. In this embodiment, the cross-section of the square rod 34 is rectangular, but it can also be a polygonal structure to prevent the fixing plate 61 from rotating relative to the square rod 34. The structure is ingeniously designed, which improves the compactness and stability of the connection between the support member 3 and the base 33.

[0054] Furthermore, in this embodiment, a square hole 612 is provided at the center of the fixing plate 61. The cross-sectional structure of the square hole 612 matches the cross-sectional structure of the square rod 34. The fixing plate 61 is sleeved on the square rod 34 to prevent the fixing plate 61 from rotating relative to the support member 3 and to ensure the stability of the connection between the support base 6 and the support rod.

[0055] The assembly process of the fixed structure in this embodiment: First, install the sealing ring 5 into the second receiving groove 23 of the suction cup hard plastic part 2; insert the bottom end of the support 3 into the first receiving groove 22 of the suction cup hard plastic part 2; finally, pass the screw 4 through the first connecting hole 21 from the bottom end of the suction cup hard plastic part 2 and thread it into the first threaded groove 31 of the support 3 to complete the assembly of the entire fixed structure.

[0056] When the suction cup needs to be replaced, simply unscrew screw 4 to remove the entire suction cup assembly consisting of the soft plastic part 1 and the hard plastic part 2. After replacing the new suction cup assembly, tighten screw 4 again.

[0057] The working principle of this mobile phone holder: When the first rotating plate 62 is rotated, the connecting cylinder 621 rotates synchronously with it. The inclined structure of the first guide groove 6211 gradually raises the position of the rotating shaft 64 (because one end of the first guide groove 6211 gradually increases in height). Since the rotating shaft 64 is fixedly connected to the support member 3, the rise of the rotating shaft 64 will drive the support member 3 to move upward as a whole, thereby pulling the suction cup shaft 14 of the suction cup hard plastic part 2 and the suction cup soft plastic part 1 upward. This causes the volume of the receiving chamber 11 at the bottom of the suction cup soft plastic part 1 to shrink, forming a negative pressure, and finally achieving tight adhesion between the suction cup and the adsorption surface. Conversely, when the first rotating plate 62 is rotated in the opposite direction, the first guide groove 6211 lowers the position of the rotating shaft 64, the support member 3 descends, the receiving chamber 11 returns to normal pressure, and the suction cup releases its adsorption.

[0058] In this embodiment, the phone holder angle adjustment process is as follows: When the first rotating plate 62 is rotated, the rotating shaft 64 slides within the first guide groove 6211 of the connecting cylinder 621. Because the first guide groove 6211 is inclined, it can drive the support plate 63 to rise and fall, thereby adjusting the angle of the panel 8. After adjusting to a suitable angle, the rotating shaft 64 engages with the positioning groove 6212 for fixation. The positioning groove 6212 can stably lock the negative pressure state, preventing the first rotating plate 62 from reversing due to vibration, collision, or accidental contact, ensuring the suction cup maintains its suction force and improving safety. Simultaneously, in the locked state, no continuous external force is required, reducing component fatigue. Meanwhile, the guide post 611 slides along the second guide groove 622, ensuring stability during rotation.

[0059] In this embodiment, the mobile phone holder transforms the "rotation action" into the "lifting and lowering of the support 3" through a mechanical structure, realizing convenient control of suction cup adsorption and release. There is no need to manually press the suction cup, making operation more labor-saving. The tilt angle design of the first guide groove 6211 can accurately control the shrinkage of the receiving chamber 11, ensuring that the negative pressure is moderate (it can firmly adsorb without damaging the suction cup due to excessive pulling force).

[0060] This completes the process of fixing the replaceable suction cup and the corresponding mobile phone holder in this preferred embodiment.

[0061] Combination Figure 9The second embodiment of the replaceable suction cup fixing structure and the corresponding mobile phone holder provided by this utility model is as follows: like Figure 9-12 As shown, a fixing structure for a replaceable suction cup includes a soft plastic suction cup 1a, a hard plastic suction cup 2a, a support member 3a, and a screw 4a. The soft plastic suction cup 1a is made of elastic rubber material, and its bottom end has a recessed receiving chamber 11a, which is used to form a negative pressure suction with the suction surface. The hard plastic suction cup 2a is aligned with the center of the soft plastic suction cup 1a and connected as a whole. The hard plastic suction cup 2a has a first connecting hole 21 penetrating through the upper and lower surfaces in the middle. The support member 3a is disposed above the hard plastic suction cup 2a. The bottom end of the support member 3a has a first threaded groove 31, and the top end is used to connect an external bracket. In this embodiment, the external bracket is used to support the mobile phone. The screw 4a penetrates the first connecting hole 21a of the hard plastic suction cup 2a and is threadedly connected to the first threaded groove 31a of the support member 3a.

[0062] The suction cup hard plastic part 2a and the screw 4a are integrally molded structures. Compared with the assembly method of the parts in the first embodiment, this integral molding design greatly reduces the assembly steps.

[0063] Combination Figure 12 and 13 As shown, the operation process is simple and convenient in actual use. First, align the receiving chamber 11a of the suction cup soft plastic part 1a with the target suction surface, press firmly to expel the air in the receiving chamber 11a, creating a negative pressure to adhere to the surface. At this time, the one-piece molded suction cup hard plastic part 2a and screw 4a provide solid support for the entire suction structure. Next, align the first threaded groove 31a at the bottom of the support part 3a with the screw 4a, and rotate the suction cup part (including the suction cup soft plastic part 1a, the suction cup hard plastic part 2a, and the one-piece molded screw 4a) to make the support part 3a and the screw 4a tightly connected, completing the installation with the support part 3a. Finally, connect the external mobile phone holder to the top of the support part 3a, and you can place your mobile phone for use. When the suction cup soft plastic part 1a needs to be replaced due to aging or damage, the replacement process is very simple. Since the suction cup hard plastic part 2a and the support part 3a are connected by screws 4a, simply rotate the suction cup part (including the suction cup soft plastic part 1a, the suction cup hard plastic part 2a, and the one-piece screw 4a) in the opposite direction. The screw 4a will separate from the support part 3a, and the suction cup part can be removed as a whole. After replacing the new suction cup part, simply reconnect it according to the installation steps. The whole process does not require complicated tools and can be done by the user, greatly improving the convenience of use.
