Description

Technical Field

[0001] This utility model relates to the field of home furnishing, and in particular to a clothes rack with lifting function. Background Technology

[0002] There are two main types of adjustable clothes racks: electric and manual. Electric adjustable clothes racks use a motor to raise and lower the frame, while manual adjustable clothes racks have a control box fixed to the wardrobe. A hand crank or pull rod is used to lower the vertical rod, making it easier for users to hang and retrieve clothes. However, both existing solutions have limitations: electric adjustable clothes racks require a motor, resulting in higher costs, and rely on electricity for operation, making control more complex; manual adjustable clothes racks lack control over the frame's tilting angle, leading to excessively high descent heights and inconvenience for users.

[0003] Based on the above, existing clothes racks with lifting functions need further improvement. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of existing lifting clothes racks and provide a clothes rack with lifting function. The horizontal bar structure is locked in the downward state through a linkage structure composed of a vertical rod, a connecting structure, an elastic element and a first buffer device, which limits the descent height of the horizontal bar structure and locks it at the most suitable height, thereby improving the user experience.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a clothes rack with lifting function, comprising a horizontal bar structure, a pull rod, a vertical bar, and a control box. The control box contains an elastic element, a connecting structure, and a first buffer device. The connecting structure has a first connecting end, a second connecting end, and a third connecting end. The upper end of the pull rod is sleeved on the horizontal bar structure. One end of the vertical bar is connected to the horizontal bar structure, and the other end is disposed on the first connecting end. The connecting structure is rotatably disposed within the control box. One end of the elastic element is rotatably disposed within the control box, and the other end is hinged to the second connecting end. One end of the first buffer device is rotatably disposed within the control box, and the other end is hinged to the third connecting end. When the vertical bar rotates around the rotation center of the connecting structure to a preset position, the elastic element is compressed, and the direction of its elastic force is substantially consistent with the rotation direction of the vertical bar.

[0006] This invention features three connecting ends in its connecting structure, allowing the vertical rod, elastic element, and first buffer device to rotate around the rotation center of the connecting structure. Pulling the lever lowers the horizontal rod structure downwards. When the horizontal rod structure descends to the preset position where the vertical rod has rotated around the rotation center of the connecting structure, the elastic force generated by the elastic element on the second connecting end is essentially in the same direction as the rotation of the vertical rod. This elastic force pushes the vertical rod to continue rotating, while the first buffer device is in a fully extended state, limiting the rotation of the vertical rod and locking it at the preset position. The horizontal rod structure is then fixed at a set height. Compared to existing technologies, this invention's clothes rack with lifting function limits the descent height of the horizontal rod structure, locking it at a set height, resulting in a better user experience. Furthermore, it has a simple structure and control method, and low production costs.

[0007] During the rotation of the vertical rod to the preset position, when the second connecting end is located to the left of the rotation center of the connecting structure in the vertical direction, the elastic element generates an upward elastic force on the second connecting end along the length of the elastic element, causing the second connecting end to rotate to the upper left and drive the vertical rod to rotate accordingly, thus resetting the vertical rod. When the rotation center of the second connecting end and the connecting structure are located in the same vertical direction, the elastic force generated by the elastic element on the second connecting end pushes the second connecting end to continue rotating to the right of the rotation center of the connecting structure. At this time, since the rotation requires stretching the first buffer device, and the first buffer device is already in a fully stretched state, the vertical rod cannot rotate on its own, thus forming a lock.

[0008] Preferably, the rotation center of the connecting structure is perpendicular to the line connecting the first connecting end and the second connecting end, and the third connecting end is disposed opposite to the second connecting end; since the elastic element needs to be stretched when the vertical rod is reset upward, the elastic element plays a limiting role during the reset process; since the first buffer device needs to be stretched when the vertical rod is rotated downward to the preset position, the first buffer device plays a limiting role during this process.

[0009] Preferably, the first buffer device is a pneumatic device, including a first pneumatic rod and a first piston. The first pneumatic rod is rotatably disposed in the control box, and the first piston is slidably disposed in the first pneumatic rod, with the third connecting end disposed on the first piston. When the vertical rod is flipped downwards, the third connecting end flips upwards accordingly, causing the first piston to extend out of the first pneumatic rod.

[0010] Preferably, the control box includes a housing and a base that are recessed, the housing and the base enclosing the control cavity, and the edges of the housing and the base are provided with notches, the notches enclosing the clearance groove for the vertical rod to move.

[0011] Preferably, the clearance groove allows the vertical rod to rotate at an angle of 90°.

[0012] Preferably, the control cavity is provided with a second buffer device, including a second pneumatic rod and a second piston. The second piston is slidably disposed on the second pneumatic rod and the upper end of the second piston is disposed on the rotation trajectory of the vertical rod. When the vertical rod flips down to abut against the second piston, the second buffer device begins to work.

[0013] Preferably, the control cavity is provided with a mounting groove, and the second buffer device is disposed on the mounting groove to fix the second pneumatic rod and prevent it from rotating.

[0014] Preferably, the control cavity is provided with a top block, and when the vertical rod is in its original state, the vertical rod abuts against the top block; when the vertical rod rotates around the rotation center of the connecting structure to a preset position, the first buffer device is in a fully stretched state.

[0015] Preferably, the crossbar structure includes a crossbar and a sleeve. The sleeve is slidably fitted onto the crossbar, and the width of the crossbar structure can be adjusted by the sleeve's fitting length to flexibly adapt to different numbers of clothes hanging needs. The sleeve is provided with a limiting strip, and the crossbar is provided with a groove. The limiting strip corresponds to the groove, and the sleeve is tightly fitted onto the crossbar through the limiting strip to prevent the sleeve from rotating on its own.

[0016] Preferably, the pull rod includes a rod body, a rotating component disposed at the upper end of the rod body, and a handle disposed at the lower end of the rod body. The rotating component is rotatably disposed on the crossbar. Because the crossbar structure is relatively high, the user can flip and lower the crossbar structure by pulling the handle and the transmission of the linkage structure, thereby hanging clothes on the crossbar structure, resulting in a good user experience.

[0017] Preferably, it also includes a corner piece, which has a first connecting hole and a second connecting hole, the sleeve is inserted into the first connecting hole, and the vertical rod is inserted into the second connecting hole. Attached Figure Description

Detailed Implementation

[0030] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "horizontal", "inner", and "outer" is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing this utility model and simplifying the description, and does 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, it should not be construed as a limitation of this utility model.

[0031] See Figures 1 to 8This embodiment discloses a clothes rack 1 with lifting function, including a horizontal bar structure 2, a pull rod 3, a vertical bar 4, and a control box 5. The control box 5 is provided with an elastic element 51, a connecting structure 52, and a first buffer device 53. The connecting structure 52 is provided with a first connecting end 521, a second connecting end 522, and a third connecting end 523. The upper end of the pull rod 3 is sleeved on the horizontal bar structure 2. One end of the vertical bar 4 is connected to the horizontal bar structure 2, and the other end is disposed on the first connecting end 521. The connecting structure 52 is rotatably disposed in the control box 5. One end of the elastic element 51 is rotatably disposed in the control box 5, and the other end is hinged to the second connecting end 522. One end of the first buffer device 53 is rotatably disposed in the control box 5, and the other end is hinged to the third connecting end 523. When the vertical bar 4 rotates around the rotation center of the connecting structure 52 to a preset position, the elastic element 51 is compressed, and the direction of its elastic force is basically consistent with the rotation direction of the vertical bar 4.

[0032] See Figure 2 Specifically, the connecting structure 52 is symmetrically arranged on both sides of the vertical rod 41.

[0033] See Figures 2 to 7 The rotation center of the connecting structure 52 is perpendicular to the line connecting the first connecting end 521 and the second connecting end 522, and the third connecting end 523 is arranged opposite to the second connecting end 522. Since the second connecting end 522 and the third connecting end 523 are hinged to the elastic element 51 and the first buffer device 53 respectively, their relative arrangement allows for limiting and buffering the vertical rod 4 in different rotational directions, locking the vertical rod 4 in two different preset positions.

[0034] See Figures 2 to 7 When the vertical rod 4 flips downward, the elastic element 51 rotates clockwise and gradually compresses, while the first buffer device 53 rotates counterclockwise and gradually stretches. At this time, the elastic element 51 plays a buffering role. When the vertical rod 4 flips upward, the elastic element 51 rotates counterclockwise and gradually resets, while the first buffer device 53 rotates clockwise and gradually compresses. At this time, the first buffer device 53 plays a buffering role.

[0035] See Figures 2 to 7 To achieve the buffering and limiting effect of the first buffer device 53 on the movement of the vertical rod 4, the first buffer device 53 is a pneumatic device, including a first pneumatic rod 531 and a first piston 532. The first pneumatic rod 531 is rotatably disposed in the control box 5, the first piston 532 is slidably disposed in the first pneumatic rod 531, and the third connecting end is disposed on the first piston 532.

[0036] See Figures 1 to 8The control box 5 includes a housing 54 and a base 55 that are recessed. The housing 54 and the base 55 enclose a control cavity 56. The edges of the housing 54 and the base 55 are provided with notches 57. The notches 57 enclose a clearance groove 58 for the vertical rod 4 to move.

[0037] See Figures 2 to 8 The control box 5 is provided with a decorative piece 510, which is sleeved on the vertical rod 4 and is used to cover the decorative clearance groove 58. Specifically, the clearance groove 57 allows the vertical rod 41 to rotate at an angle of 90°.

[0038] See Figures 4 to 7 In order to buffer the vertical rod 4 when it flips downward, the second buffer device 59 is provided in the control cavity, including a second pneumatic rod 591 and a second piston 592. The second piston 592 is slidably disposed on the second pneumatic rod 591 and the upper end of the second piston 592 is disposed on the rotation trajectory of the vertical rod 4.

[0039] See Figure 8 In order to fix the second pneumatic rod 591 on the control box 5, the control cavity 56 is provided with a mounting groove 561, and the second buffer device 59 is disposed on the mounting groove 561.

[0040] See Figures 4 to 7 The control cavity 56 is provided with a top block 562, and the vertical rod 4 abuts against the top block 562. When the vertical rod rotates around the rotation center of the connecting structure 52 to a preset position, the first buffer device 53 is in a fully stretched state. In this solution, the top block 552 is used to limit the rotation angle of the vertical rod 41 to flip upward, so that the horizontal rod structure 2 stops at a set height.

[0041] See Figures 4 to 8Specifically, quadrants are drawn with the rotation center of the connecting structure 52 as the origin. The side where the first buffer device 53 is located is divided into the first quadrant and the fourth quadrant from top to bottom, and the side where the second buffer device 59 is located is divided into the second quadrant and the third quadrant from top to bottom. When the second connecting end 522 is located in the second quadrant or the third quadrant, the elastic element 51 pushes the second connecting end 522 to rotate upward. When the second connecting end 522 is located at the boundary line between the third quadrant and the fourth quadrant, the vertical rod 4 is locked. The second connecting end 522 of this scheme rotates around the rotation center of the connecting structure, which can drive the elastic element 51 to compress or stretch. When the second connecting end 522 is located in the second quadrant or the third quadrant, the elastic force of the elastic element 51 on the connecting structure 52 points to the second quadrant or the third quadrant. The elastic element 51 can push the second connecting end 522 to rotate upward, so that the vertical rod 4 flips upward and resets, thereby resetting the horizontal rod structure 2. When the second connecting end 522 is located at the boundary line between the third quadrant and the fourth quadrant, the elastic force generated by the elastic element 51 on the connecting structure 52 points to the fourth quadrant. At the same time, due to inertia, the rotation direction of the connecting structure 52 also points to the fourth quadrant. At this time, the connecting structure 52 has a tendency to rotate towards the fourth quadrant, but the first buffer device 53 is already in a fully stretched state and cannot be stretched further to make the connecting structure 52 continue to rotate towards the fourth quadrant. Thus, the connecting structure 52 is locked at this rotation angle, realizing the locked state of the vertical rod 4, and the horizontal rod structure 2 is locked at the set height.

[0042] See Figure 1 , Figure 2 , Figure 9 The crossbar structure 2 includes a crossbar 21 and a sleeve 22. The sleeve 22 is slidably fitted onto the crossbar 21. The sleeve 22 is provided with a limiting strip 221, and the crossbar 21 is provided with a groove 211. The limiting strip 221 corresponds to the groove 211. In this design, the width of the crossbar structure 2 can be flexibly adjusted by adjusting the length of the sleeve 22 fitted onto the crossbar 21, adapting to different needs for hanging clothes, thus demonstrating strong practicality.

[0043] See Figure 1 , Figure 2 , Figure 9 Specifically, the outer walls of the crossbar 21 and the sleeve 22 are provided with anti-slip textures.

[0044] See Figures 1 to 3 To make it easy to pull down the clothes rack 1, the pull rod 3 includes a rod body 31, a rotating component 32 disposed at the upper end of the rod body 31, and a handle 33 disposed at the lower end of the rod body 31. The rotating component 32 is rotatably disposed on the crossbar 21.

[0045] See Figure 2Specifically, the rotating component 32 is provided with a mounting hole 321, and the rotating component 32 is mounted on the crossbar 21 through the mounting hole 321.

[0046] See Figure 1 , Figure 2 and Figure 10 To connect the horizontal bar structure 2 and the vertical bar 4, a corner piece 6 is also included. The corner piece 6 has a first connecting hole 61 and a second connecting hole 62. The sleeve 22 is inserted into the first connecting hole 61, and the vertical bar 4 is inserted into the second connecting hole 62. The corner piece 6 in this design makes the clothes rack 1 detachable, saving overall packaging volume.

[0047] This invention features three connecting ends in its connecting structure, allowing the vertical rod 4, elastic element 51, and first buffer device 53 to rotate around the rotation center of the connecting structure 52. Pulling the pull rod 3 causes the horizontal rod structure 2 to tilt downwards. When the horizontal rod structure 2 descends to the preset position where the vertical rod 4 has rotated around the rotation center of the connecting structure 52, the elastic force generated by the elastic element 51 on the second connecting end 522 is essentially in the same direction as the rotation of the vertical rod 4. This elastic force pushes the vertical rod 4 to continue rotating, while the first buffer device 53 is in a fully stretched state, limiting the rotation of the vertical rod 4 and locking it at the preset position. Thus, the horizontal rod structure 2 is fixed at the set height. Compared to existing technologies, this invention's clothes rack 1 with lifting function limits the descent height of the horizontal rod structure 2, locking it at the set height, resulting in a better user experience. Furthermore, it has a simpler structure and control method, and lower production costs.

Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
