Description

Technical Field

[0001] This utility model relates to a lifting device suitable for ceramic tiles. Background Technology

[0002] In many fields such as home furnishing, construction, and decoration, lifters are frequently used to raise or adjust the height of objects, playing a vital role in practical applications. Taking tile lifters as an example, they are widely used in the tile laying process. The main function of tile lifters is to adjust the height of the tiles, thereby ensuring the flatness of the tile installation, effectively improving construction efficiency, and guaranteeing the quality of the decoration.

[0003] However, existing tile lifters on the market have some shortcomings. Their complex structural design not only increases manufacturing difficulty and cost, but also leads to operational inconvenience and delays in construction. More importantly, this complex structure affects the stability of the tile lifter. If the lifter is not stable enough during tile laying, uneven tiles can easily occur, affecting the overall finish and potentially requiring rework, resulting in unnecessary waste. Therefore, the problems of complex structure and insufficient stability in existing tile lifters urgently need to be addressed. Summary of the Invention

[0005] The present invention solves the above-mentioned technical problems through the following technical solution: A tile lifter, comprising: The guide support rod includes a first end and a second end; The base is installed at the first end; A base is movably fitted onto the guide support rod, and a receiving cavity is provided inside the base; The lifting support is connected to the base and extends to one side of the base; A driving component is installed inside the accommodating cavity and sleeved on the guide support rod; A first elastic element is installed in the accommodating cavity and connected to the driving element. The first elastic element applies an elastic force to the driving element to keep it separated from the guide support rod. A rotating handle is rotatably connected to the base. A portion of the rotating handle extends into the accommodating cavity and is connected to the driving member.

[0008] Preferably, the adjusting member has a rectangular hole through which the guide support rod passes, and the third elastic member causes the adjusting member and the guide support rod to tilt relative to each other. The end of the adjusting member closer to the rotating handle is close to the first end, and the other end of the adjusting member is close to the second end.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use.

[0021] It should be noted that in the claims and specification of this patent, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one" does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0022] like Figures 1-3 As shown, the ceramic tile lifter of this application includes a guide support rod 1, a base 2, a base 3, a lifting support part 4, a drive component 5, a first elastic component, a rotating handle 6, a snap-fit ​​component 7, a second elastic component, an adjusting component 8, a third elastic component, a micro-descent switch 9, and a fast-descent switch 10.

[0023] The guide support rod 1 has a base 2 and a movable base 3 at both ends. The base 3 has a cavity 31 inside, which houses a drive component 5, a locking component 7, and an adjusting component 8. These three components are engaged or disengaged from the guide support rod 1 via first, second, and third elastic elements, respectively. Rotating the handle 6 connects to the drive component 5 to actively lift the rod. A micro-lowering switch 9, via a linkage mechanism 12, releases the locking component 7 and causes the adjusting component 8 to contact the guide support rod 1 for fine-tuning. A fast-lowering switch 10, linked to the micro-lowering switch 9, enables rapid descent. The lifting support part 4 supports the ceramic tile and is connected to the base 3, extending to one side of the base 3.

[0024] The guide support rod 1 is a vertically mounted rigid rod, which can be implemented using a metal rod with a rectangular cross-section, serving as the main support for the entire device and the guide reference for lifting and lowering movements. The base 2 is a load-bearing component fixed to the bottom of the support rod, which can be implemented using welded metal plates, providing stable foundation support. The base 3 is a movable component sleeved around the guide support rod 1, which can be implemented using a metal shell with a sliding sleeve structure, with the drive control components centrally arranged in the internal cavity 31. The drive component 5 is a rotatable friction contact component, which can be implemented using a metal sheet with a rectangular through hole, allowing adjustment of the contact pressure with the guide support rod 1 by changing the rotation angle. The rotating handle 6 is a rotatable operating component, which can be implemented using a lever structure with a rotating shaft, used to drive the drive component 5 through rotational movement. The locking component 7 is a friction component with a one-way self-locking function, which can be implemented using an inclined metal sheet, relying on a second elastic element to maintain a one-way locking state with the support rod. In this state, the locking component 7 only allows the base 3 to rise along the guide support rod 1 (from the first end to the second end) and does not allow the base 3 to descend. Adjusting element 8 refers to the contact component used for fine-tuning control, which is kept in a normally separated state by a third elastic element. Micro-drop switch 9 refers to the operating component for linkage control, which synchronously controls the action of locking element 7 disengaging from and contacting adjusting element 8 via a linkage.

[0025] Specifically, operating the handle 6 rotates the drive component 5, causing it to make frictional contact with the guide support rod 1. At this time, the base 3 moves the lifting support part 4 upward. When the drive component 5 resets, the first elastic element separates the drive component 5 from the support rod. The locking component 7 forms a one-way self-locking mechanism under the action of the second elastic element to prevent downward sliding. When fine adjustment is needed, pressing the micro-descent switch 9 pushes the locking component 7 away from the support rod through the connecting arm. At this time, the locking component 7 allows the base 3 to rise along the guide support rod 1 and also allows the base 3 to descend. At the same time, the linkage mechanism 12 drives the adjusting component 8 to contact the support rod and generate reverse friction. Since the linkage mechanism 12 is located between the micro-descent switch 9 and the guide support rod 1, its movement space is limited. Therefore, the micro-descent switch 9 can be used to slowly control the descent of the base 3. The fast-descent switch 10 triggers double unlocking by directly linking with the micro-descent switch 9, allowing the base 3 to slide down quickly.

[0026] Through the above technical solution, this application effectively solves the stability and operability problems caused by the complex structure of existing lifting devices. It significantly reduces the number of parts, achieves precise control through a mechanical linkage mechanism, ensures automatic reset after operation through elastic elements, guarantees safety during the lifting process through a one-way locking mechanism, and features a compact overall structure that is easy to maintain. It is particularly suitable for tile construction scenarios requiring frequent height adjustments.

[0027] This application further proposes that the guide support rod 1 is a rectangular rod, the driving member 5 is a rectangular piece, and the driving member 5 has a rectangular hole for the guide support rod 1 to pass through. In the default state, the first elastic member makes the driving member 5 perpendicular to the guide support rod 1.

[0028] The guide support rod 1 is a rectangular rod, meaning it has at least two mutually perpendicular planes, providing stable guidance and support through planar contact. The driving component 5 is a rectangular plate, meaning it has a thin plate-like structure with a rectangular outer contour. Specifically, it can be a stamped metal plate, forming a surface contact fit with the guide support rod 1 through a rectangular hole. The inner wall of the rectangular hole forms a sliding fit clearance with the surface of the guide support rod 1. In the default state, the first elastic element makes the driving component 5 perpendicular to the guide support rod 1.

[0029] Through the above technical solution, the matching form of the rectangular rod and the rectangular hole in this application avoids the circumferential sliding degree of freedom generated by the matching of the traditional cylindrical rod and the circular hole. Through the interaction of the four planar contact surfaces, the radial offset of the driving component 5 relative to the guide support rod 1 is restricted.

[0030] This application further proposes that the snap-fit ​​7 adopts a rectangular plate structure, and a rectangular hole is opened on the snap-fit ​​7 for the guide support rod 1 to pass through. The second elastic member applies an elastic force to make the drive member 5 and the guide support rod 1 form an inclined relationship. One end of the snap-fit ​​7 near the rotating handle 6 is close to the second end of the guide support rod 1, and the other end is close to the first end.

[0031] The second elastic element applies an inclined force, which means that an asymmetrical load is generated by the elastic element. For example, a compression spring is used to apply an eccentric force on one side of the snap-fit ​​7 so that the axis of the snap-fit ​​7 forms an angle with the guide support rod 1.

[0032] Specifically, the snap-fit ​​component 7 forms a clearance fit with the guide support rod 1 through a rectangular hole. The biasing force of the second elastic element keeps the snap-fit ​​component 7 in an inclined state. When the guide support rod 1 is subjected to axial load, the inclined end face of the snap-fit ​​component 7 forms a wedge-shaped contact with the side wall of the guide support rod 1. Under unidirectional load, the frictional force of the contact surface between the snap-fit ​​component 7 and the guide support rod 1 increases with the increase of load, preventing reverse movement.

[0033] Through the above technical solution, this application solves the problem of unstable engagement between the snap-fit ​​component 7 and the guide support rod 1. The precise fit between the rectangular hole and the guide support rod 1 eliminates radial clearance, and the self-locking effect formed by the inclined elastic layout can resist external loads and prevent accidental disengagement.

[0034] This application further proposes that the adjusting member 8 has a rectangular hole through which the guide support rod 1 passes, and the third elastic member makes the adjusting member 8 and the guide support rod 1 tilt relative to each other, with one end of the adjusting member 8 near the rotating handle 6 close to the first end, and the other end of the adjusting member 8 close to the second end.

[0035] Specifically, the third elastic element can be a helical spring sleeved on the outside of the guide support rod 1. The two ends of the spring abut against the adjusting element 8 and the wall of the accommodating cavity 31 of the base 3, respectively, forcing the adjusting element 8 to form an inclined contact state with the guide support rod 1. The positional difference between the two ends of the adjusting element 8 means that the end closer to the rotating handle 6 is closer to the base 2, while the other end is farther away from the base 2. Specifically, the asymmetrical force state can be achieved by distributing the preload of the elastic element, forming a stable tilt angle.

[0036] Specifically, the elastic force of the third elastic element forces the adjusting member 8 to tilt, at which point the adjusting member 8 remains in a stable state separated from the guide support rod 1. When fine-tuning of the height is required, the micro-switching switch drives the driving member 5 to contact the guide support rod 1, generating a reverse frictional force. Since the linkage mechanism 12 is located between the micro-descent switch 9 and the guide support rod 1, its movement space is limited, thus the micro-descent switch 9 can achieve slow descent control.

[0037] This application further proposes a fixed handle 11, which is installed on the base 3 on one side where a rotating handle 6 is provided, and the rotating handle 6 rotates closer to the fixed handle 11.

[0038] Among them, the fixed handle 11 refers to the structural component fixed to one side of the base 3, which is used to provide a stable grip support.

[0039] With the above technical solution, when the operator rotates the handle 6, its rotation trajectory is close to the installation position of the fixed handle 11. At this time, the operator can form a double support by holding the fixed handle 11 and the handle 6, thereby stabilizing the movement direction of the base 3 during the adjustment process and preventing the base 3 from shaking due to uneven force.

[0040] This application further proposes that the first elastic element is a spring sleeved on the guide support rod 1, the second elastic element is a spring sleeved on the guide support rod 1, and the third elastic element is a spring sleeved on the guide support rod 1.

[0041] The spring fitted onto the guide support rod 1 refers to a spiral elastic component that is wound around the guide support rod 1 along its axial direction, with both ends of the spring fixedly connected to corresponding components. Specifically, a compression spring or a tension spring can be used, with the inner diameter of the spring slightly larger than the diameter of the guide support rod 1 to create a clearance fit.

[0042] Through the above technical solution, in this application, when the rotating handle 6 drives the driving component 5 to rotate, the spring of the first elastic element is compressed axially along the guide support rod 1, generating a linear restoring force opposite to the direction of rotation, ensuring that the driving component 5 automatically resets after operation. The spring of the second elastic element maintains a constant preload during the one-way engagement of the latching component 7. The spring of the third elastic element can also efficiently and automatically reset to achieve instant switching of the contact state. Furthermore, in this application, the axial sleeve layout of the springs integrates the motion control of the driving component 5, the latching component 7, and the adjusting component 8 onto a single guide support rod 1, reducing the thickness of the mechanism. The coaxial arrangement of the three elastic elements avoids the stacking of multiple support layers, improving space utilization. The linear elastic characteristics of the springs reduce the probability of engagement failure during operation, significantly improving equipment stability.

[0043] This application further proposes a micro-drop switch 9 including a V-shaped connecting arm 91, a connecting part 93, and a pressing part 92. The bottom of the V-shaped connecting arm 91 contacts the snap-fit ​​member 7. The pressing part 92 is connected to one end of the V-shaped connecting arm 91 and is located outside the receiving cavity 31. One end of the connecting part 93 is connected to the other end of the V-shaped connecting arm 91 and is located inside the receiving cavity 31. The linkage mechanism 12 is connected to the other end of the connecting part 93.

[0044] The V-shaped connecting arm 91 is a rigid connecting member with two branches, whose bottom fulcrum contacts the snap-fit ​​member 7 to form a bidirectional force transmission structure. The pressing part 92 is an operating interface located on the outside of the V-shaped connecting arm 91, facilitating finger pressing operation. The connecting part 93 is a transmission member extending into the receiving cavity 31.

[0045] With the above technical solution, when the pressing part 92 is subjected to external force, the V-shaped connecting arm 91 deflects at an angle with the bottom contact point as the fulcrum. One branch drives the linkage mechanism 12 to rotate through the connecting part 93, while the other branch directly pushes the locking piece 7 to disengage from the guide support rod 1. The specific included angle design of the V-shaped connecting arm 91 ensures that the displacement of the two branches is in a predetermined ratio, thus ensuring the synchronization of the disengagement action of the locking piece 7 and the contact action of the adjusting piece 8.

[0046] This application further proposes a linkage mechanism 12 including a rotating member 121, a first rotating shaft 122, and a second rotating shaft 123. The rotating member 121 is located between the connecting part 93 and the guide support rod 1; the first rotating shaft 122 is rotatably connected to the connecting part 93 and one end of the rotating member 121; the second rotating shaft 123 is rotatably connected to the rotating member 121 and one end of the adjusting member 8.

[0047] The rotating component 121 is a rigid connecting member disposed between the connecting part 93 and the guide support rod 1, and its function is to transmit the mechanical movement between the micro-drop switch 9 and the adjusting component 8. The first rotating shaft 122 is the movable fulcrum connecting the connecting part 93 and the rotating component 121, and its function is to convert the rotation of the micro-drop switch 9 into the oscillation of the rotating component 121. The second rotating shaft 123 is the movable fulcrum connecting the rotating component 121 and the adjusting component 8, and its function is to convert the oscillation of the rotating component 121 into the movement of the adjusting component 8.

[0048] Through the above technical solution, when the micro-descent switch 9 is pressed, its connecting part 93 drives the rotating member 121 to shift angularly around the first rotating shaft 122. The swing of the rotating member 121 is transmitted to the adjusting member 8 through the second rotating shaft 123, forcing the adjusting member 8 to overcome the elastic force of the third elastic member and contact the guide support rod 1. The double-pivot structure formed by the first rotating shaft 122 and the second rotating shaft 123 allows a single operation of the micro-descent switch 9 to simultaneously trigger the disengagement of the latching member 7 and the contact of the adjusting member 8. The rotating member 121 is positioned within a limited space, thereby enabling micro-descent control.

[0049] This application further proposes to provide a through hole in the V-shaped connecting arm 91, and to pass the guide support rod 1 through the through hole.

[0050] With the above technical solution, when the micro-lowering switch 9 needs to perform height adjustment, the operator rotates the micro-lowering switch 9 to drive the V-shaped connecting arm 91 to rotate. The rotation trajectory of the V-shaped connecting arm 91 is restricted to a plane parallel to the extension direction of the guide support rod 1. This constraint effectively prevents the V-shaped connecting arm 91 from axially shifting during rotation. Compared with the traditional hinge structure, it can reduce the swing amplitude caused by the fit clearance and improve stability.

[0051] This application further proposes that the adjusting member 8 is provided with a hook portion 13 extending to the second end at one end near the fast-descent switch 10, and the fast-descent switch 10 is provided with a latching hook portion 14, which can be rotated at any angle to engage with the hook portion 13.

[0052] The hook portion 13 refers to the protruding structure extending from the end of the adjusting member 8, which forms an effective supporting contact surface when the quick-descent switch 10 is activated. The latch portion 14 refers to the bent portion provided at the end of the quick-descent switch 10, whose inclined angle complements that of the hook portion 13, thereby realizing the self-aligning function during rotation.

[0053] With the above technical solution, when the fast-closing switch 10 is rotated in the direction of the rotating handle 6 by an external force, the inclined surface of the hook part 14 contacts the hook part 13, forcing the adjusting member 8 to move.
