Description

Technical Field

[0001] This utility model relates to the field of daily necessities technology, and in particular to a height adjustment device and a floor-to-ceiling drying rack using the same. Background Technology

[0002] A floor-to-ceiling clothes drying rack is a drying device whose top is against a mounting surface such as a ceiling and whose bottom is against a supporting surface such as the ground.

[0003] As shown in the existing patent document with announcement number CN212925500U, the length of the existing top-to-bottom main pole is generally not adjustable, requires customization, and has poor applicability. Utility Model Content

[0004] The purpose of this invention is to provide a height adjustment device and a floor-to-ceiling drying rack using the same, which can at least solve one of the above-mentioned problems.

[0005] According to one aspect of the present invention, a height adjustment device is provided, comprising a mounting frame, a lifting member, a first spring, a lever mechanism, and a movable member. The lifting member is movably mounted on the mounting frame, and the movable member is movably fitted around the outer periphery of the lifting member. The first spring is fitted around the outer periphery of the lifting member and its two ends respectively abut against the mounting frame and the movable member. The lever mechanism is mounted on the mounting frame and its resistance end cooperates with the movable member.

[0006] Therefore, by applying external force to the power end of the lever mechanism, the resistance end of the lever mechanism can be tilted upward, causing the moving parts to rise, which in turn causes the lifting parts to rise, thus completing the height adjustment of the lifting parts.

[0007] In some embodiments, the lever mechanism includes a frame, a first pin, and a second pin. The middle part of the frame is movably mounted to the mounting frame via the second pin. The first pin is located at the first end of the frame and at the bottom of the movable part. The first end of the frame is the resistance end of the lever mechanism, and the second end of the frame is the power end of the lever mechanism.

[0008] In some embodiments, the height adjustment device further includes a shim, which is mounted on the mounting bracket, with a first end of the movable member engaging with a first pin and a second end of the movable member engaging with the shim.

[0009] When an external force is applied to the second end of the frame and causes the second end of the frame to move downward, the first pin will first lift the first end of the movable part so that the movable part is in a limited engagement with the lifting part, and then drive the second end of the movable part away from the pad. The movement of the movable part will simultaneously drive the lifting part to rise.

[0010] After the external force acting on it disappears, the movable part returns to its original position under the action of the first spring and is in a horizontal state, with the bottom of the movable part in contact with the first pin and the washer respectively.

[0011] In some implementations, the thickness of the gasket is equal to the outer diameter of the first pin.

[0012] In some embodiments, the movable component has a first limiting hole that mates with the lifting component. Thus, after the first pin lifts the first end of the movable component, the first limiting hole is in an inclined state. At this time, the movable component will limit the lifting component, and the rise of the movable component will simultaneously pull the lifting component to rise together.

[0013] In some embodiments, the lever mechanism further includes a third pin and a control handle. The third pin is located at the second end of the frame, and the first end of the control handle is movably fitted around the outer periphery of the third pin, while the second end extends away from the third pin. Thus, the control handle effectively increases the length of the power arm, resulting in a labor-saving effect and facilitating user operation.

[0014] In some embodiments, the height adjustment device further includes a limiting mechanism, which includes a limiting member and a second spring. The limiting member is fitted around the outer periphery of the lifting member, and the second spring is fitted around the outer periphery of the lifting member with its two ends abutting against the mounting frame and the limiting member, respectively. The first end of the limiting member is limited and engaged with the mounting frame. Under the action of the second spring, the limiting member is in an inclined state when there is no external force. Therefore, the limiting mechanism acts as a limiter, ensuring that the lifting member is limited when the lever mechanism is working. When an external force is applied to the second end of the limiting member, the limiting member is made to be in a horizontal state, thus achieving the unlocking function. At this time, the lifting member is not limited by the limiting member and can move freely under the action of external force. The extension and retraction of the lifting member can be manually controlled. When no external force is applied to the limiting member, the limiting member always remains in an inclined state under the action of the second spring, thus limiting the lifting member and ensuring that the lifting member will not fall. However, if an external force is applied to the lever mechanism, the force that drives the lifting member to rise will be significantly greater than the limiting force of the limiting member. Therefore, the lifting member can rise. After the external force acting on the lever mechanism disappears, the moving part can be reset under the action of the first spring, and the lifting member remains stationary under the action of the limiting member.

[0015] In some embodiments, the limiting member has a second limiting hole that cooperates with the lifting member. Thus, when the limiting member is in an inclined state, the second limiting hole will abut against the lifting member to limit its movement; when the limiting member is in a horizontal state, the second limiting hole will not restrict the lifting member, allowing the lifting member to move freely and facilitating manual adjustment.

[0016] According to another aspect of the present invention, a floor-to-ceiling drying rack is also provided, comprising a column, a first mounting part installed at the upper end of the column and cooperating with a first mounting surface, and a second mounting part installed at the lower end of the column and cooperating with a second mounting surface. It also includes a lifting part installed at the second mounting part and cooperating with the column. The lifting part is the height adjustment device mentioned above. The mounting frame is fixedly installed at the second mounting part. The lifting part cooperates with the bottom of the column. Under the action of the lever mechanism, the lifting part can lift the column.

[0017] In some embodiments, the second mounting part includes a second mounting base and a sleeve. The second mounting base mates with the second mounting surface. The bottom of the mounting bracket is fixedly connected to the second mounting base. The sleeve is fitted around the outer periphery of the mounting bracket and is located between the column and the second mounting base. The bottom of the column is movably fitted inside the sleeve and abuts against the top of the lifting member. An clearance groove is provided on the sleeve.

[0018] The beneficial effects of this utility model are:

[0019] 1. This utility model provides a novel height adjustment device with a new structure. This device can lift the lifting component through a lever mechanism to meet the usage requirements of height adjustment.

[0020] 2. The height adjustment device of this utility model uses a lever mechanism to transmit force, which is not only simple in structure and low in cost, but also convenient to adjust and use;

[0021] 3. The height adjustment device of this utility model adopts a pure mechanical structure to realize many functions such as height adjustment, limit and manual extension control, which is low in cost and durable.

[0022] 4. The floor-to-ceiling drying rack uses this height adjustment device, which can adjust the height of the uprights, making it suitable for installation scenarios of different heights. It is highly adaptable and easy to operate.

[0023] 5. The uprights of the floor-to-ceiling drying rack can adopt a telescopic sleeve structure, which can be quickly adapted and installed in spaces of various heights, making it convenient to use. Attached Figure Description

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0037] Example 1

[0038] Figure 1-3 The diagram schematically illustrates a floor-to-ceiling drying rack according to one embodiment of the present invention.

[0039] like Figure 1-3 As shown, the height adjustment device includes a mounting frame 61, a lifting member 62, a first spring 63, a lever mechanism 64, and a movable member 65. The lifting member 62 is movably mounted on the mounting frame 61, and the movable member 65 is movably fitted onto the outer periphery of the lifting member 62. The first spring 63 is fitted onto the outer periphery of the lifting member 62, and its two ends abut against the mounting frame 61 and the movable member 65, respectively. The lever mechanism 64 is mounted on the mounting frame 61, and its resistance end cooperates with the movable member 65.

[0040] Preferably, the lever mechanism 64 includes a frame 641, a first pin 642, and a second pin 643. The middle part of the frame 641 is movably mounted to the mounting frame 61 via the second pin 643. The first pin 642 is located at the first end of the frame 641 and at the bottom of the movable part 65. The first end of the frame 641 is the resistance end of the lever mechanism 64, and the second end of the frame 641 is the power end of the lever mechanism 64.

[0041] Preferably, the height adjustment device further includes a shim 66, which is mounted on the mounting bracket 61. The first end of the movable member 65 engages with the first pin 642, and the second end of the movable member 65 engages with the shim 66.

[0042] When an external force is applied to the second end of the frame 641 and causes the second end of the frame 641 to move downward, the first pin 642 will first lift the first end of the movable part 65 so that the movable part 65 is in a limited engagement with the lifting part 62, and then drive the second end of the movable part 65 away from the pad 66. The rise of the movable part 65 will simultaneously drive the lifting part 62 to rise as well.

[0043] After the external force acting on it disappears, the movable part 65 returns to its original position under the action of the first spring 63 and is in a horizontal state, with the bottom of the movable part 65 in contact with the first pin 642 and the washer 66 respectively.

[0044] Preferably, the thickness of the gasket 66 is equal to the outer diameter of the first pin 642.

[0045] Preferably, the lifting member 62 includes a rod-shaped portion and a supporting portion disposed at the upper end of the rod-shaped portion.

[0046] As a further preferred embodiment, the rod-shaped portion is a cylindrical rod, and the supporting portion is a disc-shaped or block-shaped portion.

[0047] Preferably, the movable part 65 is provided with a first limiting hole 651 that cooperates with the lifting part 62.

[0048] As a further preferred embodiment, the diameter of the first limiting hole 651 is slightly larger than the outer diameter of the rod-shaped portion of the lifting member 62.

[0049] Therefore, when an external force is applied to the second end of the frame 641 and causes the second end of the frame 641 to move downward, the first pin 642 lifts the first end of the movable member 65, and the movable member 65 is in an inclined state. At this time, the movable member 65 can limit the lifting member 62 through the first limiting hole 651. If the movable member 65 continues to rise, it will pull the lifting member 62 to rise together. After the external force disappears, the movable member 65 returns to a horizontal state under the action of the first spring 63. At this time, the first limiting hole 651 will not limit the lifting member 62.

[0050] Preferably, the lever mechanism 64 further includes a third pin 644 and a control handle 645. The third pin 644 is disposed at the second end of the frame 641, and the first end of the control handle 645 is movably fitted onto the outer periphery of the third pin 644, while the second end extends away from the third pin 644.

[0051] The control handle 645 is engaged with the frame 641 and can rotate around the third pin 644 under the action of external force. When not in use, it can be rotated to a position parallel to the lifting member 62 to save space; when in use, it can be rotated to a horizontal position so that the bottom abuts against the frame 641, applying downward pressure, and the frame 641 can be rotated by the control handle 645.

[0052] Therefore, the setting of control handle 645 is equivalent to increasing the length of the power arm, which saves effort and makes it easier for users to operate.

[0053] Preferably, the height adjustment device further includes a limiting mechanism 67, which includes a limiting member 671 and a second spring 672. The limiting member 671 is fitted around the outer periphery of the lifting member 62, and the second spring 672 is fitted around the outer periphery of the lifting member 62 with its two ends abutting against the mounting frame 61 and the limiting member 671 respectively. The first end of the limiting member 671 is limited and engaged with the mounting frame 61. Under the action of the second spring 672, the limiting member 671 is in an inclined state when no external force is applied.

[0054] As a further preferred embodiment, the limiting member 671 is plate-shaped, and its first end has a limiting opening 671b that cooperates with the mounting bracket 61 for limiting. Under the action of no external force, the limiting member 671 is in an inclined state with the first end higher and the second end lower under the action of the second spring 672 (not shown in the figure).

[0055] Therefore, the limiting mechanism 67 acts as a limiting mechanism, ensuring that the lifting member 62 is limited when the lever mechanism 64 is working. When an external force is applied to the second end of the limiting member 671, the limiting member 671 is in a horizontal state, which unlocks the lifting member 62. At this time, the lifting member 62 is not limited by the limiting member 671 and can move freely under the action of external force. The lifting member 62 can be extended and retracted manually. When no external force is applied to the limiting member 671, the limiting member 671 always remains in an inclined state under the action of the second spring 672, which limits the lifting member 62 and ensures that the lifting member 62 will not fall. However, if an external force is applied to the lever mechanism 64, the force that drives the lifting member 62 to rise will be significantly greater than the limiting force of the limiting member 671. Therefore, the lifting member 62 can rise. After the external force on the lever mechanism 64 disappears, the moving member 65 can be reset under the action of the first spring 63, and the lifting member 62 remains stationary under the action of the limiting member 671.

[0056] Preferably, the limiting member 671 has a second limiting hole 671a that cooperates with the lifting member 62. Thus, when the limiting member 671 is in an inclined state, the second limiting hole 671a will abut against the lifting member 62 to limit it. When the limiting member 671 is in a horizontal state, the second limiting hole 671a will not restrict the lifting member 62, and the lifting member 62 can move freely, which facilitates manual adjustment.

[0057] As a further preferred embodiment, the diameter of the second limiting hole 671a is slightly larger than the outer diameter of the rod-shaped portion of the lifting member 62.

[0058] In addition, when an external force is applied to the second end of the limiting member 671, in order to keep the limiting member 671 accurately in a horizontal state, the mounting bracket 61 of this embodiment is also provided with a limiting bolt for limiting the second end of the limiting member 671. When an external force is applied to the second end of the limiting member 671, the limiting member 671 can deform and contact the limiting bolt. At this time, the second limiting hole 671a on the limiting member 671 will not limit the lifting member 62.

[0059] The working principle of the height adjustment device of this utility model is as follows:

[0060] When no external force is applied, the movable part 65 is in a horizontal state under the action of the first spring 63, the limiting part 671 is in an inclined state under the action of the second spring 672, and the lifting part 62 remains in a fixed position under the action of the limiting part 671.

[0061] like Figure 3 As shown, when downward pressure is applied to the control handle 645, the control handle 645 and the second end of the frame 641 move downward together around the second pin 643, while the first pin 642 moves upward around the second pin 643, lifting the first end of the movable member 65. When the first end of the movable member 65 is lifted higher than the second end, the movable member 65 is in an inclined state. At this time, the movable member 65 can limit the lifting member 62 through the first limiting hole 651. If external force is applied again, the movable member 65 will continue to rise and disengage from the pad 66, while simultaneously pulling the lifting member 62 upward together. After the external force disappears, the movable member 65 returns to a horizontal state under the action of the first spring 63. At this time, the first limiting hole 651 will not limit the lifting member 62. However, since the limiting member 671 always remains in an inclined state under the action of the second spring 672, it can limit the lifting member 62. That is, the lifting member 62 will not move downward after being lifted. By repeating the above actions, the required height can be achieved.

[0062] When it is necessary to shorten the height of the lifting component 62 or retract the lifting component 62, an external force needs to be applied to the limiting component 671 to unlock it before the height of the lifting component 62 can be manually adjusted.

[0063] Specifically, when an upward pressure is applied to the second end of the limiting member 671, the limiting member 671 changes from an inclined state to a horizontal state with the same height at both ends. At this time, the second limiting hole 671a of the limiting member 671 will not limit the lifting member 62, and the first limiting hole 651 of the movable member 65 will also not limit the lifting member 62. Therefore, the lifting member 62 can be raised or lowered relative to the mounting bracket 61 by manual adjustment.

[0064] The advantages of this height adjustment device compared to traditional structures are:

[0065] 1. This utility model provides a novel height adjustment device, which can lift the lifting member 62 through the lever mechanism 64 to meet the height adjustment requirements;

[0066] 2. The height adjustment device of this utility model uses a lever mechanism 64 to transmit force, which is not only simple in structure and low in cost, but also convenient to adjust and use;

[0067] 3. The height adjustment device of this utility model adopts a pure mechanical structure to realize many functions such as height adjustment, limit and manual extension control, which is low in cost and durable.

[0068] Example 2

[0069] Figure 4-7 The diagram schematically illustrates a floor-to-ceiling drying rack according to one embodiment of the present invention.

[0070] like Figure 4-7 As shown, the floor-to-ceiling drying rack includes a column 1, a first mounting part 2 installed on the upper end of the column 1 and cooperating with a first mounting surface, and a second mounting part 3 installed on the lower end of the column 1 and cooperating with a second mounting surface. It also includes a lifting part 6, which is installed on the second mounting part 3 and cooperates with the bottom of the column 1. The lifting part 6 adopts the height adjustment device shown in Embodiment 1.

[0071] The mounting bracket 61 of the lifting part 6 is fixedly installed on the second mounting part 3. The lifting member 62 of the lifting part 6 cooperates with the bottom of the column 1. Under the action of the lever mechanism 64, the lifting member 62 can lift the column 1.

[0072] Preferably, the second mounting part 3 includes a second mounting base 31 and a sleeve 33. The second mounting base 31 mates with the second mounting surface. The bottom of the mounting bracket 61 is fixedly connected to the second mounting base 31 by fasteners such as screws. The sleeve 33 is fitted around the outer periphery of the mounting bracket 61 and is located between the column 1 and the second mounting base 31.

[0073] The bottom of the column 1 is movably fitted into the sleeve 33 and abuts against the top of the lifting member 62.

[0074] The bottom of the column 1 is fitted with an end cap 14, the upper end of the sleeve 33 is fitted with a limiting kit 34, the lower end of the column 1 is movably fitted into the sleeve 33 and is limited and engaged with the limiting kit 34, and the bottom of the column 1 abuts against the top of the lifting member 62 through the end cap 14.

[0075] The sleeve 33 is provided with a clearance groove 331. The mounting bracket 61, frame 641, control handle 645, and limit member 671 of the lifting part 6 all extend out of the clearance groove 331 for easy operation.

[0076] Preferably, the column 1 is a telescopic sleeve structure, the column 1 includes an outer tube 11 and an inner tube 12, the first end of the inner tube 12 is movably fitted into the outer tube 11, the second end is connected to the second mounting base 31, the end of the outer tube 11 away from the inner tube 12 is fitted into the sleeve 33, and the end cap 14 is fitted into the bottom end of the outer tube 11.

[0077] Preferably, the column 1 also includes a locking device 13, which includes a locking kit 131 and a spring pin 132. The outer tube 11 has a positioning hole 111 that engages with the end of the spring pin 132. The locking kit 131 is fitted onto the upper end of the outer tube 11 and the spring pin 132 passes through the positioning hole 111. The inner tube 12 has multiple stop holes 121 that are spaced apart along the height of the inner tube 12 and engage with the spring pin 132. Thus, by manually adjusting the extension and retraction of the inner tube 12, and with the spring pin 132 locking in place with the stop holes 121, the overall length of the column 1 can be adjusted.

[0078] Preferably, the column 1 also includes a limiting spring 15, which is disposed at the bottom end of the inner tube 12 and cooperates with the outer tube 11 for limiting. When there is no external force, the limiting spring 15 opens and abuts against the inner wall of the outer tube 11, while when there is external force, the limiting spring 15 closes, so as not to affect the movement of the inner tube 12.

[0079] Preferably, the first mounting part 2 further includes a first anti-slip structure 22 provided on one end face that contacts the first mounting surface, and the first anti-slip structure 22 is mounted on the upper end face of the first mounting base 21. The second mounting part 3 further includes a second anti-slip structure 33 provided on one end face that contacts the second mounting surface, and the second anti-slip structure 33 is mounted on the lower end face of the second mounting base 32.

[0080] As a further preferred embodiment, both the first anti-slip structure 22 and the second anti-slip structure 33 can be anti-slip protrusions or anti-slip pads, etc. The anti-slip protrusions can specifically be dot-shaped anti-slip protrusions or block-shaped anti-slip protrusions.

[0081] To increase drying space and functionality, the floor-to-ceiling drying rack of this embodiment also includes a first extension part 4 and a second extension part 5. The first extension part 4 can be a drying tray, and the second extension part 5 can be a drying rod, both of which can be installed on the outer periphery of the inner tube 12 of the column 1 in a set manner.

[0082] The working principle of this utility model's floor-to-ceiling drying rack is as follows:

[0083] Step 1, Coarse Adjustment: During installation, first quickly adjust the length of the column 1 according to the height of the installation space. Adjust the length by extending or retracting the inner tube 12 relative to the outer tube 11. Then, lock the position after adjustment by using the locking device 13. The specific method is as follows: First, put the locking device 13 in the unlocked state. By stretching or shortening the inner tube 12, the inner tube 12 is extended or retracted relative to the outer tube 11. After it is roughly in place, operate the locking device 13 so that the spring pin 132 passes through the positioning hole 111 and is inserted into the corresponding stop hole 121 to complete the locking.

[0084] The second step is fine-tuning: fine-tuning and position locking are performed by lifting part 6. Since the first step is coarse adjustment, there is no actual contact or tight contact between the top and bottom mounting surfaces of the floor-to-ceiling drying rack. At this time, by operating lifting part 6, lifting part 61 lifts column 1, so that the top and bottom ends of the floor-to-ceiling drying rack are respectively pressed against the first and second mounting surfaces, achieving a stable effect.

[0085] The advantages of this floor-to-ceiling drying rack compared to traditional structures are:

[0086] 1. The floor-to-ceiling drying rack uses this height adjustment device, which can adjust the height of the upright 1, making it suitable for installation scenarios of different heights. It is highly adaptable and easy to operate.

[0087] 2. The upright column 1 of the floor-to-ceiling drying rack can adopt a telescopic sleeve structure, which can be quickly adapted and installed in spaces of various heights, making it convenient to use;

[0088] 3. This utility model provides a novel floor-to-ceiling drying rack with a completely new structure.
