Description

Technical Field

[0001] This utility model relates to the field of lifting device technology, and specifically to a lifting device with a novel adjustment mechanism. Background Technology

[0002] A tile jack is used to elevate tiles attached to a wall. To use it, place the jack under the tile and press it down to raise the tile and keep it at a horizontal position, preventing it from shifting due to gravity. Remove the jack after the adhesive has cured.

[0003] For example, Chinese Utility Model Patent No. CN202420983652.0 discloses a jacking device, including a fixed part and a lifting part disposed on the fixed part. The fixed part includes a base and a guide rod disposed on the base. The lifting part is slidably disposed on the guide rod and has a lifting plate. A climbing mechanism is disposed on the guide rod. An adjusting handle is rotatably disposed on the lifting part, and the inner end of the adjusting handle abuts against the climbing mechanism. Pressing the adjusting handle can cause the climbing mechanism to tilt relative to the guide rod. Continuing to press the adjusting handle can push the lifting part to move upward along the guide rod. The lifting part is provided with a locking mechanism that engages with the guide rod, and the locking mechanism restricts the lifting motion. The lifting part moves downwards, and a fine-tuning piece is movably mounted on the guide rod. One end of the fine-tuning piece abuts against the lifting part, and the other end of the fine-tuning piece is hinged to a fine-tuning switch. The fine-tuning switch has an adjusting rod, and the bottom end of the adjusting rod abuts against the upper surface of the locking mechanism. Pressing the fine-tuning switch can drive the fine-tuning piece to tilt and engage with the guide rod. Continuing to press the fine-tuning switch will cause the adjusting rod to drive the locking mechanism to tilt slightly downwards, thereby achieving fine-tuning of the lifting part. A descent control component is provided above the locking mechanism, and the bottom end of the descent control component abuts against the upper surface of the locking mechanism. Pressing the descent control component can drive the locking mechanism to be perpendicular to the guide rod. At this time, the lifting part moves rapidly downwards along the guide rod.

[0004] The structure is quite complex and has many parts. For example, there is an adjustment rod on the fine-tuning switch to control the position of the fine-tuning plate, and an abutment plate is extended on the descent control component to effectively prevent the descent control component from detaching from the control hole. Therefore, further improvements to its structure are needed. Utility Model Content

A set of limiting plates is installed on the outer periphery of the guide column. One side of the limiting plate abuts against the side wall of the lifting seat, and the lower end face of the other side of the limiting plate abuts against the lifting seat with a spring to keep the limiting plate in an inclined state and engage with the guide column. The second limiting piece is sleeved on the outer periphery of the guide post and located on the upper end face of the first limiting piece. A second spring is abutted between the upper end face of one side of the second limiting piece and the lifting seat, so that the second limiting piece is kept in a horizontal state and is movably set on the outer periphery of the guide post. The slow-descent wrench can rotate up and down and is hinged to the other side of the limiting plate two. The lower end face of the slow-descent wrench is formed with an arc-shaped protrusion one. The arc-shaped protrusion one is used to push the limiting plate one to move so that the limiting plate one is released from the locking between the guide post, and at the same time drives the limiting plate two to tilt and lock with the guide post. The quick-descent button is located on the upper surface of the slow-descent wrench and can be moved back and forth. The upper surface of the slow-descent wrench has an arc-shaped protrusion. The inner side of the quick-descent button has a push slope. The push slope is used to push the slow-descent wrench and the limit plate to move so that the limit plate can be released from the engagement with the guide post.

[0007] Preferably, one end of the rapid descent button extends out of the side wall of the lifting seat and is provided with a pressing part, and the other end of the rapid descent button abuts against the lifting seat with a spring.

Detailed Implementation

[0022] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-6 As shown, a lifting device with a novel adjustment mechanism includes a guide column 1, a base 2 at the lower end of the guide column 1, a lifting seat 3 movably arranged on the outer periphery of the guide column 1, a top plate 4 installed on the front side of the lifting seat 3 for abutting against the lower end surface of the tile, thereby raising the height of the tile, and a limit plate 5 and a limit plate 6 are respectively arranged inside the lifting seat 3. The limiting piece 5 is fitted around the outer periphery of the guide post 1. One side of the limiting piece 5 abuts against the side wall of the lifting seat 3, and the lower end face of the other side of the limiting piece 5 abuts against the lifting seat 3 with a spring 7, so that the limiting piece 5 is kept in an inclined state and is engaged with the guide post 1. Limiting piece 2 6 is sleeved on the outer periphery of guide post 1 and located on the upper end face of limiting piece 1 5. A spring 2 8 is abutted between the upper end face of one side of limiting piece 2 6 and lifting seat 3 so that limiting piece 2 6 is kept in a horizontal state and is movably set on the outer periphery of guide post 1. The slow-descent wrench 9 can rotate up and down and is hinged to the other side of the limiting plate 6. The lower end face of the slow-descent wrench 9 is formed with an arc-shaped protrusion 10. When it is necessary to fine-tune the height of the lowering seat 3, after pressing down the slow-descent wrench 9, the limiting plate 5 can be moved through the arc-shaped protrusion 10, so that the limiting plate 5 is released from the locking between the guide post 1, and at the same time, the limiting plate 6 is driven to be slightly tilted and locked with the guide post 1. At this time, the height of the lifting seat 3 can be finely adjusted. The quick-descent button 11 is movable back and forth and is located on the upper end face of the slow-descent wrench 9. The upper end face of the slow-descent wrench 9 is formed with an arc-shaped protrusion 12. The inner side of the quick-descent button 11 is formed with a pushing inclined surface 13. When it is necessary to quickly lower the height of the lifting seat 3, after pressing the quick-descent button 11, its pushing inclined surface 13 will push the slow-descent wrench 9 and the limiting plate 5 to move, so that the limiting plate 5 is released from the engagement with the guide post 1. At this time, the height of the lifting seat 3 can be quickly adjusted.

[0024] This utility model, through the design of a slow-descent wrench 9 and a fast-descent button 11, can achieve fast-descent and slow-descent adjustment effects respectively. The structure is simple and easy to assemble and disassemble. When the slow-descent wrench 9 is pressed down, the arc-shaped protrusion 10 pushes the limiting plate 5 to move, so that the limiting plate 5 is released from the engagement with the guide post 1. At the same time, the limiting plate 6 is driven to be slightly tilted and engaged with the guide post 1. At this time, the height of the lifting seat 3 can be finely adjusted. When the fast-descent button 11 is pressed, its pushing inclined surface 13 will push the slow-descent wrench 9 and the limiting plate 5 to move, so that the limiting plate 5 is released from the engagement with the guide post 1. At this time, the height of the lifting seat 3 can be quickly adjusted.

[0025] One end of the descent button 11 extends out of the side wall of the lifting seat 3 and is provided with a pressing part 14. The other end of the descent button 11 is abutted against the lifting seat 3 by a spring 15, which provides elastic force for the automatic reset of the descent button 11. A strip-shaped hole 16 is opened in the middle of the descent button 11, and a limit shaft 17 is provided in the strip-shaped hole 16. The two ends of the limit shaft 17 are fixedly connected to the lifting seat 3 to limit the forward and backward movement of the descent button 11 and prevent the descent button 11 from falling out.

[0026] Combination Figure 5 and Figure 6 The side wall of the quick-descent button 11 is formed with a limiting guide groove 18, and the inner side wall of the lifting seat 3 is formed with a guide plate 19, which enables the quick-descent button 11 to move in a straight horizontal line. During the pressing process, the movement is stable and the control is precise.

[0027] One end of the slow-descent wrench 9 extends out of the side wall of the lifting seat 3 and is provided with a control part 20. The side wall of the lifting seat 3 is provided with a limiting opening 21 for the control part 20 to extend out. A torsion spring 22 is provided at the hinge of the slow-descent wrench 9 and the limiting plate 6 so that the control part 20 tends to rotate towards the upper side of the limiting opening 21, and the rotation angle of the control part 20 can be limited by the limiting opening 21.

[0028] The lifting seat 3 has a spring seat 23 formed inside for the spring 7 to abut against. The side wall of the lifting seat 3 has a limiting groove 24 for one side of the limiting piece 5 to abut against. When the slow-down wrench 9 applies pressure to the upper surface of one side of the limiting piece 5, the other end of the limiting piece 5 will abut against the limiting groove 24, thereby keeping the limiting piece 5 in a horizontal state and releasing the limiting piece 5 from the locking between it and the guide post 1.

[0029] The other side of the limiting piece 6 has a locking part 25, and the side of the slow-release wrench 9 is provided with a limiting block 26 for the locking part 25 to engage.

[0030] The side of the lifting seat 3 is fitted with a side cover 27 by fasteners.

[0031] The lower outer periphery of the guide post 1 is movably fitted with a limiting piece 28. One side of the limiting piece 28 abuts against the side wall of the lifting seat 3, and the lower end face of the other side of the limiting piece 28 abuts against the lifting seat 3 with a spring 29, so that the limiting piece 28 is kept in a horizontal state and movably fitted on the outer periphery of the guide post 1. The rear side of the lifting seat 3 is fixed with an upper lifting wrench 30, and the lower lifting wrench 31 is rotatably installed inside the lifting seat 3. The front end of the lower lifting wrench 31 is formed with a pushing part 32 for pushing the limiting piece 28 to move. When the user presses the lifting wrench, the limiting piece 28 and the guide post 1 will first be tilted. Then, when the user continues to press the lifting wrench, the lifting wrench will drive the lifting seat 3 to move upward along the guide post 1, thereby causing the top plate 4 on the lifting seat 3 to move upward together and lift the item.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
