Description

Technical Field

[0001] This utility model relates to the field of buoys, and more particularly to a device for preventing objects from being pressed down and removed. Background Technology

[0002] With the rapid popularization of electronic products, smartphones, tablets, and e-readers have become increasingly important parts of daily life due to their diverse functions. However, this also leads to user dependence, with users spending long periods immersed in device operation, affecting learning efficiency, work performance, and physical and mental health. Although users are conscious of controlling their usage time, relying solely on personal self-control is often insufficient for sustained and effective management. Current mainstream solutions rely on software-based focus apps, which programmatically disable device functions or lock the screen during specific periods to limit usage. However, software locking mechanisms have significant limitations: their protection only applies to the operating system level. Users can easily bypass the restrictions through conventional or unconventional means such as entering a backup password, forcibly restarting the device, switching to safe mode, or exploiting system vulnerabilities. Teenage users, in particular, often quickly circumvent these restrictions due to their technological knowledge, significantly diminishing the effectiveness of software solutions. Therefore, there is an urgent need for a physical locking device that can directly act on the electronic device itself, mechanically securing it to prevent unauthorized removal or operation, thus providing a more stable and harder-to-avoid usage control method.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0022] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] In the control of electronic product use, existing technologies rely on software-implemented locking mechanisms to limit usage time. However, because these mechanisms allow unlocking and necessary operations, users can bypass the restrictions by testing passwords or using unconventional methods, making it impossible to prevent the electronic product from being removed and thus hindering the achievement of the goal of controlling usage time. The core problem lies in the lack of physical isolation in the locking mechanism, making the locked state easily bypassed and consequently affecting the reliability of the control mechanism.

[0025] For example, in a home-based guardianship scenario, a guardian might activate attention-control software to limit a teenager's smartphone usage time. Even after the software locks the device, the electronic product may retain emergency call functionality or a system recovery option. The teenager could then repeatedly enter the password or utilize the recovery mode to successfully unlock the phone and continue using it, rendering the control intent ineffective. Furthermore, this breach allows the electronic product to be removed by the user even while locked, directly causing the usage time control process to fail as intended.

[0026] If the above problems are not solved, the mechanism for controlling usage time will not operate stably, users' dependence on electronic products will persist, and the effectiveness of time management will be affected. Therefore, there is an urgent need for a device that can physically lock electronic products.

[0027] like Figure 1As shown, an object clamping and anti-removal device includes a housing 100; the housing 100 has an insertion groove 110 for allowing the object to be clamped 500 to be inserted and removed; the housing 100 also has a receiving groove 120 communicating with the insertion groove 110; a support frame 200 is provided in the receiving groove 120; a connecting rod 300 is movably connected to the support frame 200; a clamping assembly 400 is rotatably connected to the end of the connecting rod 300 away from the support frame 200; the clamping assembly 400 is configured to move in and out of the insertion groove 110; the support frame 200 has a motor 210 for driving the connecting rod 300 to move so that the clamping assembly 400 moves closer to or further away from the insertion groove 110, thereby clamping and releasing the object to be clamped 500.

[0028] This application relates to a device for preventing removal by pressing down on an object. Its design aims to solve the problem in the prior art of effectively locking electronic products using physical means to prevent them from being removed by the user. In practical applications, the insertion slot 110 refers to a channel structure formed within the housing 100 for accommodating the object to be clamped 500. It can be implemented using a rectangular cross-section slot or a U-shaped opening slot. For example, a groove adapted to the size of the electronic device can be directly constructed inside the housing 100 through injection molding, or an adjustable-width sliding sidewall structure can be used to accommodate electronic products of different thicknesses / widths. Its main purpose is to achieve orderly insertion and initial positioning of the object to be clamped 500. The receiving slot 120 refers to an auxiliary space within the housing 100 that communicates with the insertion slot 110. It can be implemented using a laterally extending cavity or an annular enclosed chamber. For example, a chamber perpendicularly intersecting the insertion slot 110 can be opened on the side / top of the housing 100. Its main purpose is to provide a movement path for the clamping assembly 400 and ensure reliable communication with the insertion slot 110. Furthermore, the clamping component 400 refers to the terminal component that performs the clamping action, primarily for achieving stable clamping and controllable release of the object 500. Specifically, the motor 210 is the power source that drives the connecting rod 300. It can be implemented using a stepper motor 210 in conjunction with a crank-connecting rod mechanism. For example, the rotational motion of the motor 210 can be converted into the reciprocating swing of the connecting rod 300 via a crank, primarily to achieve automatic forward and backward control of the clamping component 400 without manual intervention. Thus, this embodiment, by integrating an automatic clamping mechanism driven by the motor 210, enables the clamping component 400 to accurately enter and exit the insertion slot 110 according to preset instructions, thereby forming a physical locking barrier. This design avoids the shortcomings of existing attention-focusing software that relies on password verification and is easily bypassed by teenagers. The irreversible locking characteristics of the mechanical structure ensure that the electronic product cannot be removed through conventional operations. Therefore, when the user attempts to remove the object 500, the clamping component 400 automatically resets to the clamping state under the drive of the motor 210, effectively blocking unconventional unlocking methods. As a preferred embodiment, the connecting rod 300 movably connected to the support frame 200 can adopt a hinged structure, so that the connecting rod 300 can swing at multiple angles under the constraint of the support frame 200, thereby adapting to the clamping requirements of objects 500 of different sizes, while ensuring the stability of the movement trajectory.

[0029] The object-clamping and anti-removal device includes a housing 100. The housing 100 has an insertion slot 110 for inserting and removing the object 500. The housing 100 also has a receiving slot 120 communicating with the insertion slot 110. A support frame 200 is provided within the receiving slot 120. A connecting rod 300 is movably connected to the support frame 200. A clamping assembly 400 is rotatably connected to the end of the connecting rod 300 away from the support frame 200. The clamping assembly 400 is configured to move in and out of the insertion slot 110. The support frame 200 has a motor 210 that drives the connecting rod 300 to move, causing the clamping assembly 400 to move closer to or further away from the insertion slot 110, thereby clamping and releasing the object 500. For example, in practical applications, when a mobile phone 500 is inserted into the insertion slot 110, the motor 210 starts and drives the connecting rod 300 to move. The connecting rod 300 drives the clamping assembly 400 into the insertion slot 110 to press against the surface of the mobile phone and achieve clamping. When release is required, the motor 210 rotates in the opposite direction, causing the connecting rod 300 to drive the clamping assembly 400 out of the insertion slot 110, allowing it to be removed. The motor 210 can specifically be a small DC motor to achieve smooth and reliable drive, ensuring that the clamping assembly 400 is accurately displaced within the insertion slot 110.

[0030] In one embodiment of this utility model, a mounting cavity 201 is formed inside the support frame 200; an output screw 220 is connected to the output shaft of the motor 210 to prevent rotation; the output screw 220 is at least partially located inside the mounting cavity 201; a nut seat 230 is threadedly connected to the output screw 220; the nut seat 230 is rotatably connected to the connecting rod 300; the clamping assembly 400 is slidably connected to the support frame 200; the rotation of the motor 210 drives the nut seat 230 to reciprocate along the output screw 220, thereby driving the clamping assembly 400 to reciprocate up and down inside the support frame 200.

[0031] Specifically, the mounting cavity 201 refers to the accommodating space formed inside the support frame 200, which aims to provide an installation environment for the drive mechanism; the anti-rotation connection refers to the mechanical connection between the output shaft of the motor 210 and the output screw 220 to prevent relative rotation, which can be achieved by keyway fit, spline connection or interference fit, to ensure that the rotational power is transmitted without slippage and to avoid phase deviation; the output screw 220 refers to a rod-shaped transmission component with continuous threads, which aims to efficiently convert rotational motion into a precise linear displacement reference; the nut seat 230 refers to a moving component that forms a threaded pair with the output screw 220, which aims to support the connecting rod 300 and achieve linear output of reciprocating motion; the rotational connection refers to a movable connection that allows relative rotation between components, reducing mechanical stress; the sliding connection refers to a guiding method that constrains the movement of components in a fixed direction, which can be achieved by linear guide rail or sliding groove structure, to strictly limit the movement trajectory of the clamping assembly 400 and eliminate lateral offset.

[0032] Specifically, after the motor 210 starts, its output shaft synchronously drives the output screw 220 to rotate through the anti-rotation connection. The nut seat 230 moves axially along the output screw 220 under the meshing action of the thread pair. Since the nut seat 230 is rotatably connected to the connecting rod 300, the connecting rod 300 converts the linear motion into a push-pull action, thereby driving the clamping assembly 400 to move up and down along the sliding connection structure of the support frame 200. This achieves the control process of the clamping assembly 400 accurately entering and exiting the insertion slot 110. This process ensures the continuity and stability of the motion trajectory through the screw-nut transmission mechanism.

[0033] In one embodiment of the present invention, the support frame 200 is provided with at least one guide rod 240; the guide rod 240 is slidably connected to the nut seat 230; the support frame 200 is also provided with a battery 260 for supplying power to the motor 210 and a circuit board for controlling the operation of the motor 210.

[0034] Among them, the guide rod 240 refers to a rigid guide element used to constrain the movement trajectory of the nut seat 230. It can be implemented using a cylindrical rod, a square rod, or a linear guide structure to provide a stable linear motion path. Its purpose is to prevent the nut seat 230 from shifting laterally during reciprocating motion. The sliding connection between the guide rod 240 and the nut seat 230 means that the nut seat 230 forms a movable connection with the guide rod 240 through a low-friction engagement. It can be implemented using a linear bearing, a sliding bushing, or an oil-impregnated bearing to reduce motion resistance and ensure smooth reciprocating motion. Its purpose is to improve motion response speed and reduce mechanical wear. The battery 260 refers to an independently powered electrochemical energy storage device. It can be implemented using a lithium-ion battery 260, a nickel-metal hydride battery, or a polymer lithium battery to provide continuous power support. Its purpose is to eliminate dependence on external power sources. The circuit board refers to a printed circuit board that integrates electronic control functions. It can be implemented using a PCB that includes a microcontroller and a motor 210 drive circuit to precisely manage the operation of the motor 210. Its purpose is to achieve automated control and reduce operational complexity. The circuit board controls the start / stop and operating parameters of the motor 210 according to preset logic, ensuring automatic triggering of the clamping action, thereby forming a complete independent technical system for motion stability and power supply. Specific operating logic settings can be selected according to requirements, which is a common practice in this field. Those skilled in the art can choose according to their needs, and will not be elaborated upon here. This application mainly provides a specific clamping and releasing device to meet the needs of some users for such mechanical devices.

[0035] In one embodiment of the present invention, the support frame 200 includes two side plates arranged opposite to each other; the two side plates are arranged opposite to each other along the axial direction of the output screw 220; the clamping assembly 400 is located between the two side plates and can slide in the up and down direction.

[0036] The support frame 200 includes two opposing side plates, which are designed to create a rigid constraint frame to limit the lateral movement of the clamping assembly 400. The two side plates are positioned opposite each other along the axial direction of the output screw 220, meaning that the extension direction of the side plates is parallel to the axis of the output screw 220. This is to ensure that the movement direction of the clamping assembly 400 is substantially perpendicular to the reciprocating movement direction of the nut seat 230, thereby optimizing space utilization. The clamping assembly 400 is located between the two side plates and can slide in the vertical direction, meaning that the clamping assembly 400 is constrained within the channel formed by the side plates to perform linear movement. Using two side plates to limit the movement direction of the clamping assembly 400 can reduce the contact area with the clamping assembly 400, thereby reducing frictional resistance. It can be understood that, under normal circumstances, the structure in which the support frame 200 and the clamping assembly 400 cooperate is an enclosed quadrilateral structure. When the clamping assembly 400 is in contact with all four side plates, there is increased frictional resistance, which is not conducive to the up-and-down reciprocating movement of the clamping assembly 400. Since the nut seat 230 reciprocates in the horizontal direction, it is relatively easy to cause the clamping assembly 400 to move in the same direction. The two side plates are mainly used to limit the movement of the clamping assembly 400 in the horizontal direction. The possible offset of the clamping assembly 400 in other directions is small, and the connecting rod 300 can be used to achieve auxiliary limiting. Therefore, at least two side plates are provided on the support frame 200 to limit the movement of the clamping assembly 400.

[0037] In one embodiment of this utility model, the outer surface of the clamping assembly 400 is provided with guide ribs 414 that cooperate with the side plate; the extending direction of the guide ribs 414 is parallel to the moving direction of the clamping assembly 400; at least two guide ribs 414 are provided on the side plate; the provision of guide ribs 414 can further reduce the contact area between the clamping assembly 400 and the side plate, thereby reducing friction; the guide ribs 414 preferably make line contact with the side plate, for example, the outward protrusion of the guide ribs 414 is set as an arc shape; in one embodiment, the outer surface of the clamping assembly 400 is provided with a plurality of protrusions (not shown in the figure) that cooperate with the side plate. Compared to the previous embodiment, the protrusions in this embodiment achieve point contact between the clamping assembly 400 and the side plate, resulting in a smaller contact area and lower frictional resistance. However, this structure is relatively difficult to manufacture. The guide rib 414, on the other hand, is easier to manufacture, and the frictional resistance of the line contact between the guide rib 414 and the side plate can meet the movement requirements of the clamping assembly 400, making it more suitable for production. The direction in which the guide rib 414 or the protrusions are used has lower frictional resistance; therefore, the support frame 200 can be constructed with four side plates surrounding the outside of the clamping assembly 400, more effectively limiting the movement direction of the clamping assembly 400. It is understood that, as... Figure 1As shown, the support frame 200 includes a rectangular frame structure consisting of four side plates connected in sequence. The frame contains a clamping assembly 400, specifically a connecting block 410 that cooperates with the side plates. The connecting block 410 is also a rectangular structure. The four sides of the connecting block 410 protrude outward to form guide ribs 414. The guide ribs 414 abut against the inner wall of the side plates to form a limiting and guiding structure.

[0038] In one embodiment of this utility model, the support frame 200 is provided with a limit switch 250 for detecting the displacement of the nut seat 230. In one embodiment, two limit switches 250 are arranged opposite each other along the axial direction of the output screw 220.

[0039] In practical applications, the limit switch 250 refers to an electromechanical sensing device used to detect the displacement state of an object. It can be implemented by mechanical microswitches, photoelectric position sensors or Hall effect sensors. Its purpose is to sense the movement position change of the nut seat 230 in real time, provide accurate displacement feedback signals for the control system, and thus establish the basis for closed-loop control of position monitoring.

[0040] Specifically, the solution of this application integrates the limit switch 250 into a predetermined position of the support frame 200. When the nut seat 230 moves along the output screw 220 to the clamping end point or the release start point, the triggering mechanism of the limit switch 250 makes physical contact or non-contact sensing with the nut seat 230, thereby generating an electrical signal and transmitting it to the circuit board. Based on this signal, the circuit board immediately cuts off the power supply to the motor 210 or adjusts the direction of the motor 210, thereby precisely limiting the range of motion of the nut seat 230, ensuring that the clamping assembly 400 completes the clamping and releasing actions within a safe range, and effectively avoiding the risk of mechanical overload caused by the continuous operation of the motor 210.

[0041] In one embodiment of this utility model, the connecting rod 300 is rotatably connected to the nut seat 230 via a first rotating shaft 310; the connecting rod 300 is rotatably connected to the clamping assembly 400 via a second rotating shaft 320; two connecting rods 300 are arranged opposite each other; at least one first rotating shaft 310 is provided; at least one second rotating shaft 320 is provided.

[0042] Specifically, the first rotating shaft 310 refers to the connecting component that enables relative rotational movement between the connecting rod 300 and the nut seat 230. It can be implemented using a pin to provide a low-friction rotational fulcrum and reduce stress concentration during movement. The second rotating shaft 320 refers to the connecting component that enables relative rotational movement between the connecting rod 300 and the clamping assembly 400. It can also be implemented using a pin structure to allow the clamping assembly 400 to adapt to angle changes during movement and maintain the vertical stability of the clamping surface. In practical applications, the connecting rods 300 can be arranged in parallel or cross configurations to form a symmetrical force distribution and counteract lateral forces and torsional effects. Specifically, having at least one first rotating shaft 310 means providing at least one rotational fulcrum in the configuration, which can be implemented using a single or multiple shafts. Having at least one second rotating shaft 320 means providing at least one rotational fulcrum at the connection point of the clamping assembly 400. It can be implemented in the same way as the first rotating shaft 310 to ensure the flexibility and durability of the connection.

[0043] In one embodiment of the present invention, the clamping assembly 400 includes a connecting block 410 and a slidingly connected pressing block 420 inside the connecting block 410; the connecting block 410 is rotatably connected to the connecting rod 300; the connecting block 410 is provided with a pressing block 420 for cooperating with the object to be clamped 500 on the side near the object to be clamped 500.

[0044] The sliding connection of the pressure block 420 within the connecting block 410 means that the pressure block 420 can move relative to the object 500 in the vertical direction within the connecting block 410. This can be achieved using a slide rail combined with a slider or guide post, etc. The purpose is to allow the pressure block 420 to dynamically adapt to the slight undulations on the surface of the object 500 to provide a buffering effect and avoid local high pressure points. The rotatable connection between the connecting block 410 and the connecting rod 300 can be understood as the connecting block 410 being able to adjust its angle around the axis of rotation of the connecting rod 300. This can be achieved using a hinge structure, which allows the clamping assembly 400 to calibrate the perpendicularity between the pressure block 420 and the surface of the object 500 in real time during movement, ensuring a uniform distribution of clamping force. The pressure block 420 is the component that directly contacts the surface of the object 500. It can be made of elastic material or hard material with a specific contour, and its purpose is to form a matching contact interface, disperse clamping pressure, and enhance frictional resistance.

[0045] In one embodiment of this utility model, a first inner cavity 413 is formed inside the connecting block 410 on the side near the object to be clamped 500; the pressing block 420 is slidably connected to the first inner cavity 413; a slot 412 is provided on the top plate 411 of the first inner cavity 413 relative to the pressing block 420; a snap-fit ​​plate 421 is provided on the side of the pressing block 420 near the top plate 411, extending toward the top plate 411 and inserted into the slot 412 and slidably connected to the slot 412; a limiting block 422 is provided on the side of the snap-fit ​​plate 421 away from the pressing block 420, which cooperates with the slot 412 to prevent the snap-fit ​​plate 421 from disengaging from the slot 412; and a plurality of springs 423 are provided between the top plate 411 and the pressing block 420.

[0046] The first inner cavity 413 refers to the accommodating space formed inside the connecting block 410. It can be implemented using a rectangular cavity, a circular cavity, or an irregularly shaped cavity. Its purpose is to provide a controlled sliding path for the pressing block 420, ensuring that the pressing block 420 moves in a predetermined direction during clamping. The slot 412 can be understood as a guide structure provided on the top plate 411. Specifically, it can be a straight slot. Its purpose is to appropriately constrain the movement trajectory of the clamping plate 421. The limiting block 422 is specifically a mechanical limiting structure provided at the end of the clamping plate 421. Its purpose is to form a physical block with the slot 412, preventing the clamping plate 421 from completely disengaging from the slot 412 under force. The spring 423 refers to an elastic buffer element. It can be implemented using a helical spring, a leaf spring, or a rubber elastomer. Its purpose is to provide dynamic buffering, absorb the impact energy during clamping, and ensure that the pressing block 420 returns to its original position smoothly.

[0047] It should be noted that, because the top plate 411 is a plate-like structure, the depth of the slot 412 cannot be too deep. This also means that the limiting structure between the slot 412 and the clamping plate 421 can only limit the displacement of the clamping plate 421 to a limited extent. However, this also allows the clamping plate 421 to have a relatively large range of free movement, which facilitates the pressure block 420 to adaptively match the uneven surface of the object to be clamped 500 under the action of the spring 423, thereby providing uniform pressure and ensuring the safety of the object to be clamped 500. At the same time, the spring 423 can effectively control the pressure applied by the pressure block 420 to the object to be clamped 500. To mitigate the problem of excessive pressure, it's understandable that when the nut seat 230 moves a significant distance, it will cause the connecting block 410 to press down a considerable distance. Using a rigid structure would significantly increase the downward pressure due to the increased movement distance. However, by indirectly transmitting the downward pressure through the spring 423, uniform pressure can be achieved, and the spring 423 can automatically absorb and store excess pressure, preventing all the downward pressure from being released onto the object 500, thus ensuring the safety of the object 500. By selecting a spring 423 with an appropriate elastic coefficient, the limit of the downward pressure can be controlled. Furthermore, the spring can adapt to the thickness of the object being clamped, thus meeting the clamping requirements for objects of varying thicknesses.

[0048] In one embodiment of this utility model, four springs 423 are evenly arranged, and the inner side of the top plate 411 and the top of the pressing block 420 are provided with protrusions that cooperate with the springs 423, thereby limiting the position of the springs 423 by means of the protrusions.

[0049] In one embodiment of the present invention, a second inner cavity 424 is formed inside the side of the pressing block 420 away from the top plate 411; an elastic rubber block 425 is fixedly provided inside the second inner cavity 424.

[0050] In practical applications, the second inner cavity 424 refers to the closed cavity structure formed inside the pressing block 420. It can be achieved by reserving space inside the pressing block 420 material or by forming a groove through mechanical processing. The purpose is to provide deformation space for the elastic material without increasing the external size. The elastic rubber block 425 can be understood as a polymer material component with reversible deformation characteristics. It can be made of elastic materials such as silicone, rubber or polyurethane. The purpose is to provide dynamic buffering capability to adapt to different surface contours.

[0051] In one embodiment of the present invention, when the limiting block 422 and the slot 412 are engaged in a limiting cooperation, the elastic rubber block 425 protrudes from the first inner cavity 413 and the second inner cavity 424.

[0052] Specifically, the protrusion of the elastic block 425 into the inner cavity can be understood as the elastic block 425 partially extending beyond the boundary of the inner cavity in the initial state. It can be made of silicone or rubber material to form a block structure with deformable characteristics, with the aim of dynamically adapting to the surface morphology of the object to be clamped 500 and increasing the effective contact area.

[0053] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
