Description

Technical Field

[0001] This utility model belongs to the field of umbrellas, specifically relating to a support and fixing structure and umbrella that is easy to remove. Background Technology

[0002] Umbrellas are tools used to shield from the sun or wind and snow. They are generally made of oiled paper, oilcloth, or plastic sheeting, and their use is gradually increasing.

[0003] Currently, most common support structures are fixed or have only limited adjustment functions, failing to meet users' flexible adjustment needs for support angle and height in different environments and usage scenarios. For example, traditional sun umbrella support structures typically only provide vertical support and lack tilt adjustment, making them inconvenient to use in strong sunlight or strong winds, resulting in poor sunshade performance and instability. In other words, existing umbrella pole support and fixing devices cannot be adjusted according to the actual usage environment, severely affecting the flexibility and safety of the structure. Furthermore, in situations with strong suction or tightly fixed structures, users cannot easily disassemble the entire support and fixing structure, increasing operational difficulty and impacting user convenience and comfort. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned problems in the existing technology by proposing a simple, stable, and easily removable support and fixing structure and umbrella that can adapt to different usage scenarios, has an adjustable angle, and is easy to disassemble and reassemble.

[0005] The objective of this utility model can be achieved by addressing the following technical problem: providing a support and fixing structure that is easy to remove, including a support base, a support placement cylinder, a rotating mechanism, and an auxiliary removal mechanism, wherein:

[0006] The support base can be adsorbed onto the surface of use;

[0007] The support placement cylinder is movably sleeved on the support base, and the support placement cylinder is used to adjust the height difference between the rotating mechanism and the support base;

[0008] The rotating mechanism is connected to the support placement cylinder. The rotating mechanism includes a rotating cylinder and an elastic element. The rotating cylinder is used to connect and fix the umbrella pole to be used. The bottom end of the rotating cylinder is movably connected to the support placement cylinder and can rotate relative to the support placement cylinder along the axial direction of the support placement cylinder. The elastic element is movably pressed against the rotating cylinder.

[0009] The auxiliary extraction mechanism is disposed on the side of the support base. The auxiliary extraction mechanism includes a bearing seat and an extraction block. The bearing seat is fixed to the side wall of the support base. The extraction block is movably inserted through the bearing seat and can abut against the use surface so that when force is applied, it drives the support base to flip and tilt around the end away from the extraction block, thereby assisting the support base to detach from the adsorption state.

[0010] In the aforementioned easy-to-remove support and fixing structure, the bearing seat includes a main body and a connecting part. The main body has an internal threaded hole, and the pull-out block has an external threaded pull-out rod. The pull-out rod is movably connected to the main body through the engagement of the external thread and the internal threaded hole. The connecting parts are symmetrically distributed on both sides of the main body and are arranged in a convex shape. Each connecting part has a connecting hole. The side wall of the support base has a locking hole, and the connecting hole is aligned with the locking hole to allow fasteners to pass through.

[0011] In the aforementioned easy-to-remove support and fixing structure, the bottom of the support base is provided with an installation groove, and a magnet is provided in the installation groove. The magnet is used to attract the support base to the surface of use.

[0012] In the aforementioned support and fixing structure for easy removal, the auxiliary removal mechanism further includes an extension handle, a connector is formed at the top of the pull-out rod, an installation hole is provided in the connector, and the extension handle is connected to the installation hole along the radial direction of the pull-out rod.

[0013] In the aforementioned easily removable support and fixing structure, the rotating mechanism further includes:

[0014] A fixed shaft has a limiting block at one end and passes through the rotating cylinder and is fixed to the support placement cylinder at the other end;

[0015] A rotating handle is threadedly connected to the end of the fixed shaft away from the limiting block. An extension plate is also provided on the rotating handle. A guide hole is provided inside the rotating cylinder. The elastic element is sleeved on the fixed shaft, and one end of the elastic element is connected to the extension plate, while the other end extends into the guide hole and is movably pressed against the rotating cylinder.

[0016] In the aforementioned easy-to-remove support and fixing structure, a rotating part is also formed on the rotating cylinder, the guide hole and the fixing shaft are both located on the rotating part, and a first annular tooth is provided on the side wall of the rotating part, and a second annular tooth is formed on the outer wall of the support placement cylinder. The first annular tooth and the second annular tooth mesh with each other to realize the rotational transmission of the rotating part relative to the support placement cylinder.

[0017] In the aforementioned easy-to-remove support and fixing structure, a first clearance arc surface is formed on the support placement cylinder, and a second clearance arc surface is formed on both the rotating part and the rotating cylinder. The curvatures of the first clearance arc surface and the second clearance arc surface are not equal.

[0018] In the aforementioned easy-to-remove support and fixing structure, the side wall of the rotating cylinder is also threadedly connected with a locking member, which is used to extend into the support placement cylinder and move against the umbrella rod.

[0019] In the aforementioned easy-to-remove support and fixing structure, the support placement cylinder is provided with an installation part along its radial direction, a locking rod is provided in the installation part, a connecting column is installed on the support base, the support placement cylinder is sleeved on the connecting column, and is movably pressed against the connecting column by the locking rod.

[0020] The technical solution adopted by this utility model to solve its technical problem is to also propose an umbrella, including one of the above-mentioned easy-to-remove support and fixing structures.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) The present invention provides an easy-to-remove support and fixing structure and umbrella. The rotating cylinder is connected to the support placement cylinder. The rotation of the rotating mechanism compresses the elastic element and presses it against the rotating cylinder, ensuring the stability of the umbrella rod when it rotates to the required tilt position with the rotating cylinder. This avoids angle deviation caused by external force or wind, and improves the safety and stability of use. At the same time, the downward force is applied by the pull-out block, which makes the support base overcome the magnetic attraction force and easily release the adsorption state. This solves the technical problem of "easy to adsorb and difficult to remove" of the traditional vacuum adsorption support structure. No additional tools or complicated operations are required, which significantly improves the user experience.

[0023] (2) By adding an extension handle, a larger lever arm can be provided during the assisted pulling operation, making it easier for users to apply external force and further reducing the force required for pulling. It is especially suitable for scenarios with strong suction or limited space. The radial connection structure of the extension handle is simple and reliable, does not affect the axial adjustment function of the assisted pulling rod, and the foldable or detachable design is easy to store without affecting the overall structural compactness, thus enhancing the humanized design of the operation.

[0024] (3) The design of the magnet allows the support base to be fixed to the metal material by magnetic attraction, avoiding the cumbersome operation of traditional screw or clamp installation, improving installation efficiency, and enhancing the versatility and portability of the structure, especially suitable for use scenarios that require frequent disassembly or temporary fixation.

[0025] (4) Through the meshing transmission of the first ring tooth and the second ring tooth, the synchronous rotation linkage between the rotating cylinder and the support placement cylinder is realized, ensuring the precise control of the umbrella rotation angle; the ring tooth structure has strong load-bearing capacity, smooth transmission, and is not easy to slip, and can achieve stable rotation under large load, extending service life; at the same time, this structure does not require an additional motor or drive device, is purely mechanical transmission, has a simple structure, low cost, and is easy to maintain, and is suitable for outdoor portable umbrella support scenarios.

[0034] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0035] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0036] like Figure 1 As shown, this solution mainly describes a removable support and fixing structure for use on umbrellas. However, this removable support and fixing structure is not limited to use on umbrellas, but can also be applied to other equipment that requires removable fixing structures.

[0037] like Figures 1 to 4 As shown, a support and fixing structure that is easy to remove includes a support base 1, a support placement cylinder 2, a rotating mechanism 3, and an auxiliary removal mechanism 4.

[0038] The support base 1 can be adsorbed onto the surface of use; the support placement cylinder 2 is movably sleeved on the support base 1, and the support placement cylinder 2 is used to adjust the height difference between the rotating mechanism 3 and the support base 1; the rotating mechanism 3 is connected to the support placement cylinder 2, and the rotating mechanism 3 includes a rotating cylinder 30 and an elastic element 31. The rotating cylinder 30 is used to connect and fix the umbrella pole to be used, and the bottom end of the rotating cylinder 30 is movably connected to the support placement cylinder 2 and can rotate relative to it along the axial direction of the support placement cylinder 2; the elastic element 31 is movably pressed against the rotating cylinder 30; the auxiliary extraction mechanism 4 is disposed on the side of the support base 1, and the auxiliary extraction mechanism 4 includes a bearing seat 40 and an extraction block 41. The bearing seat 40 is fixed to the side wall of the support base 1; the extraction block 41 is movably inserted through the bearing seat 40 and can abut against the surface of use, so that when force is applied, it drives the support base 1 to flip and tilt around the end away from the extraction block 41, thereby assisting the support base 1 to detach from the adsorption state.

[0039] This embodiment primarily aims to achieve adjustments to the umbrella's height and tilt angle, as well as convenient removal after use. Specifically, the user can attach the support base 1 to the desired surface (i.e., the usage location), such as the ground or a mounting platform, ensuring overall stability. As the support placement cylinder 2 is movably fitted onto the support base 1, the user can slide the support placement cylinder 2 up and down according to actual needs, adjusting its height relative to the support base 1 to accommodate umbrella poles or other support members of different heights. This allows the user to adjust the position of the support placement cylinder 2 according to usage requirements (such as the height of a sun umbrella). With the user connecting the umbrella pole to the rotating cylinder 30, the user can rotate the rotating cylinder 30 according to the actual usage environment (i.e., based on the angle of light and windy / snowy weather). Figure 2 As shown, when the user manually rotates the rotating drum along... Figure 2When the rotating cylinder 30 rotates relative to the support cylinder 2 in the direction of the arrow (or the opposite direction of the arrow), the rotating cylinder 30, along with the umbrella rod, can be adjusted to the desired tilt angle (e.g., the tilt angle of a parasol to block the oblique direction of sunlight). As the user applies a certain twisting force to the rotating mechanism 3, the elastic element 31 is compressed and contracted, converting into a continuous clamping force on the rotating cylinder 30, keeping it at the set angle. This clamping force effectively prevents the rotating cylinder 30 from shifting due to wind, external forces, or other vibrations. If the user wishes to adjust the angle, they only need to apply external force again to overcome the resistance of the elastic element 31 to rotate the rotating cylinder 30 again. When it is necessary to dismantle this structure, the user can use it to twist the pull-out block 41. It is worth noting that before dismantling, the bottom wall of the support base 1 is tightly fitted to the surface being used. Therefore, as the lower end of the pull-out block 41 presses against the surface being used and continuously applies pressure, it can act as a movable fulcrum, causing the bearing seat 40 and the support base 1 to move along... Figure 1 The arrow indicates that the support base 1 tilts upwards, meaning that at this point, the support base 1 is subjected to a reaction force away from the ground by the pull-up block 41, ultimately causing the force to rise around the end of the support base 1 away from the pull-up block 41 (i.e., Figure 1 The left side of the support base 1 is tilted upwards, creating an upward tilt angle. This means that the adsorption force between the support base 1 and the surface being used is completely released. After the adsorption fails, the user can easily pull the entire support structure out of the surface, completing the disassembly. Thus, this invention achieves stable fixation of the overall structure by setting an adsorbent support base 1. Combined with the movable support placement cylinder 2, the height of the rotating mechanism 3 can be flexibly adjusted to meet the height requirements of different usage scenarios. By setting an auxiliary extraction mechanism 4 on the side of the support base 1, when disassembly is required, pushing the extraction block 41 to abut against the surface creates a fulcrum, causing the support base 1 to rotate around this point, significantly reducing the force required to pull it out of the adsorbent surface. This solves the technical problem of traditional fixed structures being difficult to manually detach due to strong adsorption, improving disassembly convenience and user experience.

[0040] The support base 40 includes a main body 400 and a connecting part 401. The main body 400 has an internal threaded hole 400a. The pull-out block 41 has a pull-out rod 410 with an external thread 410a. The pull-out rod 410 is movably connected to the main body 400 through the engagement of the external thread 410a and the internal threaded hole 400a. The connecting parts 401 are symmetrically distributed on both sides of the main body 400 and are arranged in a convex shape. Each connecting part 401 has a connecting hole 401a. The side wall of the support base 1 has a locking hole 13. The connecting hole 401a is aligned with the locking hole 13 so that the fastener 42 can pass through.

[0041] like Figure 1 and Figure 3As shown, during the assembly process, the bearing seat 40 is first placed at a predetermined position on the side wall of the support base 1, so that the connecting parts 401 on both sides fit against the outer wall of the support base 1. At this time, the connecting holes 401a on the connecting parts 401 are precisely aligned with the locking holes 13 preset on the side wall of the support base 1. By inserting the fasteners 42 (screws or screws and other components) and locking them, the bearing seat 40 is firmly fixed. This convex structure design allows the connecting parts 401 to clamp the side wall of the support base 1 from both sides, which significantly improves the connection strength and torsional resistance. Then, the pull-out rod 410 (with external thread 410a) on the pull-out block 41 is screwed into the internal threaded hole 400a of the main body 400 of the bearing base 40. During rotation, the pull-out rod 410 can be fed along the thread axis to achieve reciprocating motion. In the normal state, the lower end of the pull-out rod 410 is retracted into the main body 400 to ensure that the support base 1 can be stably attached to the use surface, ensuring the stability of the umbrella body during use. In the pull-out state, the pull-out rod 410 relies on the thread to descend smoothly along the axis of the internal threaded hole 400a under axial pressure. The thread engagement has a self-locking characteristic, preventing the pull-out rod 410 from falling automatically when there is no external force, ensuring structural stability. When the lower end of the pull-out rod 410 abuts against the use surface and a thrust is continuously applied, the support base 1 can be driven to rotate. Figure 1 The left edge is flipped in the direction indicated by the arrow, causing the support base 1 to detach from the surface of use. Therefore, this structure uses internal and external threads 410a to achieve helical extension and retraction adjustment of the pull-out lever 410 on the support base 40. Users can adjust the extension length of the pull-out block 41 according to the actual ground conditions, ensuring reliable contact with the ground and forming an effective fulcrum, thus improving the stability and applicability of the lever pull-out process. Simultaneously, the U-shaped connecting part 401, in conjunction with the locking hole 13, connects with the fastener 42, enhancing the connection strength and torsional resistance between the support base 40 and the support base 1, preventing loosening or breakage during the assisted pull-out process, and improving the overall safety and durability of the structure.

[0042] Preferably, in this embodiment, an anti-loosening pad 44 (also threaded, similar to a nut structure) located on the inner wall of the support base 1 may be connected to the end of the fastener 42. (See reference...) Figure 3 As shown in the structure, with the connection hole 401a and the threaded hole aligned, the fastener 42 passes through both and connects to the anti-loosening pad 44, pressing it against the inner wall of the support base 1. This structure, while ensuring overall aesthetics, further enhances the connection stability and ease of assembly and disassembly between the carrier 40 and the support base 1. More preferably, in this embodiment, the carrier 40 and the support base 1 can be integrally injection molded, eliminating the need for assembly and disassembly operations and preventing the carrier 40 from wobbling relative to the support base 1 due to loosening of the fastener 42 during prolonged use. This ensures the structural stability and durability of the auxiliary extraction mechanism 4 for long-term use.

[0043] The bottom of the support base 1 is provided with an installation groove 10, and a magnet 11 is provided in the installation groove 10. The magnet 11 is used to attach the support base 1 to the surface of use.

[0044] like Figure 2 and Figure 3 As shown, before use, the user places the support base 1 on the target location, which is typically a metal surface such as a metal tabletop, iron railing, or metal bracket. The magnet 11, with its magnetic attraction to the metal, firmly holds the support base 1 to the surface, effectively preventing displacement or tipping even under slight external vibrations or wind. Therefore, this design avoids the cumbersome operation of traditional screw or clamp installation, improving installation efficiency while enhancing the versatility and portability of the structure, making it particularly suitable for applications requiring frequent disassembly or temporary fixation.

[0045] Preferably, in this embodiment, while ensuring the overall sealing of the mounting groove 10 structure (by adding a sealing ring), a negative pressure cavity can be formed inside the support base 1 by an auxiliary air extraction device, thereby firmly adsorbing onto the surface of use. As the pull-out block 41 drives the support base 1 to rotate, external air quickly enters the adsorption cavity (i.e., the mounting groove 10), the negative pressure disappears, and the adsorption force is completely released.

[0046] The auxiliary extraction mechanism 4 also includes an extension handle 43. The top end of the extraction rod 410 has a connector 410b, and the connector 410b has a mounting hole 410c. The extension handle 43 is connected to the mounting hole 410c along the radial direction of the extraction rod 410.

[0047] like Figure 1 and Figure 3 As shown, in this embodiment, the extension handle 43 is radially inserted into the mounting hole 410c of the connector 410b at the top of the pull-out rod 410. The connection can be ensured by means of interference fit, pin fixing or screw locking. It is worth noting that the two ends of the extension handle 43 extend laterally to form a "T"-shaped operating handle / trigger arm structure, which constitutes an operating unit that is easy to apply force. In other words, by adding the extension handle 43, a larger lever arm can be provided during the pull-out operation. As a lateral operating arm, the extension handle 43 makes it easy for the user to apply external force, further reducing the force required for pull-out, which is especially suitable for scenarios with strong suction or limited space. The radial connection structure of the extension handle 43 is simple and reliable, does not affect the axial adjustment function of the pull-out rod 410, and the detachable design is easy to store without affecting the overall structural compactness, enhancing the humanized design of the operation.

[0048] The rotating mechanism 3 also includes: a fixed shaft 32, one end of which is provided with a limiting block 320, and the other end passes through the rotating cylinder 30 and is fixed to the support placement cylinder 2; a rotating handle 33, which is threadedly connected to the end of the fixed shaft 32 away from the limiting block 320, and the rotating handle 33 is also provided with an extension plate 330; a guide hole 300 is opened in the rotating cylinder 30; an elastic element 31 is sleeved on the fixed shaft 32, and one end of the elastic element 31 is connected to the extension plate 330, and the other end extends into the guide hole 300 and moves against the rotating cylinder 30.

[0049] like Figure 1 and Figure 2 As shown, the fixed shaft 32 in this embodiment is also provided with an external thread 410a, which connects to the internal thread inside the support placement cylinder 2. Simultaneously, combined with the constraint effect of the limiting block 320 on the axial position of the fixed shaft 32, the installation and disassembly of the fixed shaft 32 and the support placement cylinder 2 can be quickly completed, significantly improving the maintainability of the structure and facilitating subsequent maintenance or component replacement. Similarly, the rotating handle 33 in this embodiment is also threadedly connected to the end of the fixed shaft 32. Therefore, when the rotating cylinder 30 drives the umbrella rod to adjust to the required tilt angle, the user can rotate the handle 33 along the... Figure 2 The fixed shaft 32 is rotated to the right, and the extension plate 330 moves synchronously along the same direction. Figure 2 Moving to the right, the right end of the elastic element 31 presses against the rotating cylinder 30 and gradually compresses and contracts. Finally, during the process of the elastic element 31 being compressed and deformed, a pressing force is applied to the rotating cylinder 30. This design not only enhances the connection strength of the rotating mechanism 3, but also realizes the convenience of angle adjustment and self-locking function through the rotating handle 33, thereby improving the practicality and operating experience of the overall device.

[0050] In this embodiment, the elastic element 31 preferably adopts a compression spring structure to ensure a stable locking function for the rotating cylinder 30 under the compression and contraction action of the elastic element 31, avoiding swaying caused by vibration or wind, and improving the stability of the structure. In addition, the guide hole 300 in this embodiment provides guidance and limiting functions for the compression, contraction and reset expansion of the elastic element 31, ensuring that absolute accuracy is maintained during frequent unlocking and locking processes.

[0051] It should be noted that the rotation locking of the rotating handle 33 relative to the fixed shaft 32 can be achieved by using a left-hand or right-hand threaded connection between the rotating handle 33 and the fixed shaft 32, thereby satisfying the requirement that the rotating cylinder 30 is positioned relative to the supporting placement cylinder 2 along... Figure 2 The locking function is shown in the direction of the arrow and in the opposite direction.

[0052] A rotating part 301 is also formed on the rotating cylinder 30. The guide hole 300 and the fixed shaft 32 are both located on the rotating part 301. A first annular tooth 301a is provided on the side wall of the rotating part 301. A second annular tooth 20 is formed on the outer wall of the supporting placement cylinder 2. The first annular tooth 301a and the second annular tooth 20 mesh with each other to realize the rotational transmission of the rotating part 301 relative to the supporting placement cylinder 2.

[0053] like Figure 2 and Figure 4 As shown, when the elastic element 31 is in its natural state (i.e., not compressed or contracted), the rotating cylinder 30 can rotate freely within a certain range. However, due to the toothed meshing design between the rotating cylinder 30 and the supporting placement cylinder 2, this design introduces a certain degree of frictional resistance. This allows the user to feel a distinct "angle positioning sense" when the rotating cylinder 30 rotates relative to the supporting placement cylinder 2. This characteristic not only allows the user to intuitively perceive angle changes but also provides a more precise tactile feedback, enhancing the operating experience. Furthermore, the rotating cylinder 30 achieves precise angle adjustment control through gear meshing with the supporting placement cylinder 2 during rotation. This gear meshing not only improves stability during rotation but also effectively prevents slippage or offset that may occur during adjustment, greatly improving the accuracy and reliability of angle adjustment. This ensures that each adjustment accurately reaches the expected position and remains stable.

[0054] A first clearance arc surface 21 is formed on the support placement cylinder 2, and a second clearance arc surface 302 is formed on both the rotating part 301 and the rotating cylinder 30. The curvatures of the first clearance arc surface 21 and the second clearance arc surface 302 are not equal.

[0055] like Figure 2 and Figure 3 As shown, in this embodiment, the rotating cylinder 30 is mounted on the support placement cylinder 2 via a fixed shaft 32. It is worth noting that there is a certain gap between the first clearance arc surface 21 and the second clearance arc surface 302. Since the curvatures of the two are different (i.e., they are not completely symmetrical or matched, but are designed with different curvatures according to the actual motion trajectory and force direction to achieve a more reasonable spatial layout and motion path optimization), clearance space is formed between the components during rotation, avoiding the impact of structural interference on the rotation operation of the rotating cylinder 30. This design optimizes the motion trajectory of the rotating mechanism 3 and improves the assembly accuracy and operational smoothness of the overall structure.

[0056] The side wall of the rotating cylinder 30 is also threaded with a locking member 34, which is used to extend into the support placement cylinder 2 and move against the umbrella rod.

[0057] like Figure 2As shown, this embodiment also includes a locking element 34 threaded into the rotating cylinder 30. When the umbrella shaft to be fixed extends into the rotating cylinder 30, the locking element 34 can be inserted into the rotating cylinder 30 and press against the umbrella shaft, thereby further enhancing the fixing effect on the umbrella shaft and preventing it from sliding or loosening during use. This locking structure is simple to operate and also ensures the stability and safety of the overall support structure. Preferably, the locking element 34 can be a locking screw or similar structure, which has low manufacturing cost, is easy to maintain and replace, and extends the service life of the support and fixing structure.

[0058] Preferably, the support cylinder 2 is provided with a through hole 22 and a handle screw 23 along its radial direction. The through hole 22 allows a copper rod (not shown in the figure) to pass through, and the handle screw 23 is used to movably tighten it. Specifically, for example... Figure 2 As shown, in this embodiment, the axis of the through hole 22 is placed horizontally. A copper rod, serving as an auxiliary tool, can be inserted into the through hole 22 to adjust the support cylinder 2 or provide support for other items. Specifically, when the user inserts the copper rod into the through hole 22, both ends of the copper rod extend to the sides of the support cylinder 2. As the manual screw is gradually tightened into the through hole 22, the copper rod is confined within the support cylinder 2. This design enhances the ease of operation when adjusting the height of the support cylinder 2, allowing the user to perform a more effortless rotation using the copper rod, thus improving comfort and efficiency.

[0059] In a further preferred embodiment, an anti-detachment groove 220 is provided on the inner wall of the through hole 22. The opening direction of the anti-detachment groove 220 is exactly aligned with the handle screw 23. As the handle screw 23 is tightened, the copper rod can be embedded and pressed against the anti-detachment groove 220, ensuring the firmness of the connection between the copper rod and the support placement cylinder 2, improving the safety and stability of the structure, effectively preventing the copper rod from being loosened or falling off, thus avoiding normal use and eliminating potential safety hazards during use.

[0060] The support placement cylinder 2 is provided with a mounting part 24 along its radial direction. A locking rod 240 is provided inside the mounting part 24. A connecting column 12 is installed on the support base 1. The support placement cylinder 2 is sleeved on the connecting column 12 and is movably pressed against the connecting column 12 by the locking rod 240.

[0061] like Figure 2 As shown, similarly, when the support placement cylinder 2 is sleeved on the connecting column 12, it can be secured by the locking rod 240. This structure enables quick assembly and disassembly of the support placement cylinder 2 and the support base 1, as well as height adjustment, enhancing the adaptability and flexibility of the device and making it suitable for various height requirements. Preferably, in this embodiment, an extension rod 240a (see reference) can also be connected to the end of the locking rod 240 along its radial direction. Figure 1As shown in the diagram, the extension rod 240a provides a better fulcrum for the user when turning the locking rod 240, thereby reducing the difficulty of operation, improving the efficiency of adjustment and locking, and avoiding inconvenience caused by limited operating space.

[0062] The working principle of this utility model's easily removable support and fixing structure and umbrella is as follows:

[0063] like Figures 1 to 4 As shown, this solution is mainly used to fix umbrellas or other similar rod-shaped supports, especially suitable for the installation and disassembly of outdoor umbrellas such as beach umbrellas and parasols. In use, the support base 1 is first attached to a metal surface (such as a metal deck or platform) using the magnet 11 at its bottom, or initially fixed using other adsorption methods (such as vacuum adsorption). After the support base 1 is fixed, the support placement cylinder 2 is movably fitted onto the support base 1. It can be adjusted up and down to adapt to different height requirements, thereby changing the height difference between the rotating mechanism 3 and the support base 1, achieving flexible adjustment of the umbrella pole support height; after the umbrella pole is inserted into the rotating cylinder 30... The locking element 34 (such as a screw) is screwed into the side wall of the rotating cylinder 30 and extends into the support placement cylinder 2, pressing against the outer wall of the umbrella rod to achieve radial limiting and fixing of the umbrella rod. At the same time, the rotating cylinder 30 in the rotating mechanism 3 is connected to the support placement cylinder 2 through the fixed shaft 32. One end of the fixed shaft 32 is provided with a limiting block 320, and the other end passes through the rotating cylinder 30 and is fixed in the support placement cylinder 2. As the elastic element 31 (such as a compression spring) is sleeved on the fixed shaft 32, one end is connected to the extension plate 330 of the rotating handle 33, and the other end extends into the guide hole 300 in the rotating cylinder 30 and moves against its inner wall, thereby providing pre-tightening force and buffer rebound function for the rotating cylinder 30.

[0064] When the umbrella orientation needs to be adjusted, the user rotates the rotating handle 33, which drives the fixed shaft 32 and the rotating cylinder 30 connected to it to rotate synchronously. Relying on the mutual meshing of the two ring teeth, the rotating cylinder 30 can rotate smoothly relative to the support placement cylinder 2, thereby driving the umbrella pole to achieve angle and direction adjustment. The cooperation between the guide hole 300 and the elastic element 31 can provide damping during rotation, prevent excessive rotation, and improve operational stability.

[0065] When the entire support structure needs to be pulled out of the surface, traditional methods often make it difficult to manually pull it out directly due to strong adsorption. This solution, however, can easily achieve this by relying on the pull-out block 41. The specific operation is as follows: when the pull-out block 41 is rotated downwards to gradually extend and press against the ground, the pull-out block 41 acts as a fulcrum, pushing the support base 1 to flip and tilt upwards around the end away from the pull-out block 41. This breaks the adsorption seal between the support base 1 and the surface or reduces the adsorption contact area, significantly reducing the pulling resistance. In this way, even under strong suction, the support base 1 (with magnet 11) can be easily detached from the surface. In addition, the horizontally set extension handle 43 makes it easy for the user to apply leverage force, improving the pulling efficiency. The entire pulling process is labor-saving and convenient, avoiding the risk of equipment damage or personal injury caused by traditional forced prying. In summary, this invention achieves the integrated functions of stable fixing, height adjustment, direction rotation, and convenient pulling of the support structure through the synergistic action of multiple components. It is particularly suitable for outdoor scenarios where frequent installation and disassembly are required.
