Description

Technical Field

[0001] This utility model belongs to the field of clothes drying racks, and more specifically, relates to an electric clothes drying rack with an external adjustable limit switch. Background Technology

[0002] The power mechanism of a clothes drying rack is responsible for controlling the raising and lowering of the drying rod and its height position. This power mechanism typically includes a motor, a controller, and a winding reel. The motor drives the winding reel to rotate to wind and unwind the steel wire rope, and limit switches are used to control the raising and lowering height of the drying rod.

[0003] For example, Chinese invention patent application number "CN118992871A" discloses "a clothes drying rack power system with an integrated wire rope protection mechanism, comprising a motor and a twisted wire reel device. The twisted wire reel device includes a housing and two twisted wire reels. The motor drives the twisted wire reels through a transmission mechanism. Each twisted wire reel is equipped with a wire rope protection mechanism. The protection mechanism consists of a rotating frame assembly, a micro switch, and first and second rollers. The rotating frame assembly is composed of first and second rotating frames and is connected to the housing through a torsion spring. During normal operation, the tension of the wire rope maintains the rotating frame in a preset position. When encountering resistance, the tension of the wire rope is lost, the rotating frame triggers the micro switch, and the motor stops. This design reduces manufacturing costs, simplifies maintenance, optimizes space utilization, meets the high standards of modern home furnishings for the performance and design of clothes drying racks, and has high safety and high efficiency."

[0004] The existing technology has the following problems: when the control switch inside the clothes drying rack, that is, the limit switch or micro switch, malfunctions, or the external remote control adjustment effect is not good, it is often impossible to adjust directly. Instead, the machine needs to be disassembled and returned to the factory for disassembly and repair, which is very inconvenient. Therefore, an electric clothes drying rack with an external adjustment limit switch that can directly adjust the height of the drying rod from the outside is provided. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an electric clothes drying rack with an external adjustable limit switch, which can realize the adjustment of the height of the drying rod directly from the outside without disassembling the machine.

[0006] This utility model discloses an electric clothes drying rack with an external adjustable limit switch, comprising: a main body housing with a drive component inside; a drying rod at the bottom of the main body housing, and a lifting component connected between the main body housing and the drying rod; a rope extending from the output end of the drive component, the rope passing through the lifting component to drive the extension and retraction of the lifting component;

[0007] A bracket is installed on the outer end face of the main unit housing. A through adjustment groove is provided on the bracket, and an external switch is movably installed in the adjustment groove.

[0008] An internal electrical terminal is installed on the outer end face of the main unit housing. The internal electrical terminal is located on one side inside the main unit housing and is electrically connected to the drive assembly.

[0009] An external electrical terminal is installed on the external switch, and the external electrical terminal can be plugged into the internal electrical terminal to switch the electrical connection / disconnection state of the two.

[0010] A trigger is installed on the lifting assembly. The trigger moves as the lifting assembly extends or retracts. The opening and closing contacts of the external switch are located on the movement trajectory of the trigger.

[0011] As a further improvement of this utility model, frame plates are installed on both ends of the main housing, and the lifting assembly and the bracket are installed on both frame plates.

[0012] The lifting assembly is installed on the side close to the main housing, while the bracket is installed on the side away from the main housing.

[0013] The vertical extension and retraction of the lifting component causes the trigger element to move vertically.

[0014] As a further improvement of this utility model, the internal electrical terminal includes an internal insertion hole, which is installed on the frame plate. The electrical interface of the internal insertion hole faces the outside of the main unit housing, and the inside of the internal insertion hole is located inside the main unit housing and is electrically connected to the drive assembly through a wire.

[0015] As a further improvement of this utility model, the external electrical terminal includes an external plug, and the external plug and the internal socket switch the electrical connection / disconnection state of the two by plugging them together.

[0019] As a further improvement of this utility model, the adjustment groove includes a movable groove, which is formed on the bracket; the external switch is slidably installed in the movable groove, and the sliding direction of the external switch in the movable groove is consistent with the extension and retraction direction of the lifting assembly.

[0020] As a further improvement of this utility model, the lifting assembly is provided with a mounting hole, and the trigger includes a telescopic shaft, which is detachably connected to the mounting hole.

[0021] As a further improvement of this utility model, the greater / smaller the extension range of the lifting component, the farther / closer the distance between the drying rod and the main housing, and the greater / smaller the moving distance of the telescopic shaft.

[0022] As a further improvement of this utility model, the telescopic shaft is foldable. When the telescopic shaft is in the folded state, the movement trajectory of the telescopic shaft is separated from the opening and closing contacts of the external switch.

[0023] Compared to existing technologies, the advantages of this invention are as follows: This solution incorporates a pluggable and detachable external limit switch. Users can activate the external limit switch when the built-in limit switch malfunctions.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] Specific Implementation Example 1: Please refer to Figure 1-9 An electric clothes drying rack with an external adjustable limit switch includes: a main body housing 11, inside which a drive assembly is provided; a drying rod 13 is provided at the bottom of the main body housing 11, and a lifting assembly is connected between the main body housing 11 and the drying rod 13; a rope extends from the output end of the drive assembly, and the rope passes through the lifting assembly to drive the extension and retraction of the lifting assembly.

[0037] It is understood that the aforementioned main unit housing 11 is a conventional clothes drying rack main unit structure. The drive assembly includes a motor 21, which is equipped with an internal switch 33. The internal switch 33 is triggered by the adjustable number of rotations of the motor 21. A reel is connected to the motor 21 to pull and retract the rope. The lifting assembly includes a scissor frame 12, through which the rope passes and connects to the drying rod 13. The scissor frame 12 serves to stabilize the rope when it pulls the drying rod 13.

[0038] A bracket 23 is installed on the outer end face of the main unit housing 11. A through adjustment groove is provided on the bracket 23, and an external switch 25 is movably installed in the adjustment groove.

[0039] An internal electrical terminal is installed on the outer end face of the main housing 11. The internal electrical terminal is located on one side inside the main housing 11 and is electrically connected to the drive assembly. An external electrical terminal is installed on the external switch 25. The external electrical terminal can be plugged into the internal electrical terminal to switch the electrical connection / disconnection state of the two.

[0040] A trigger is installed on the lifting assembly. The trigger moves as the lifting assembly extends or retracts. The opening and closing contacts of the external switch 25 are located on the movement trajectory of the trigger.

[0041] Understandably, this solution features internal and external electrical terminals, allowing the use of the external switch 25 to be manually switched via plugging and unplugging. This provides flexibility in choosing the application scenario and whether the external switch 25 is needed for limit switching. Simultaneously, the trigger follows the movement of the lifting assembly. When the lifting assembly extends, the drying rod 13 moves away from the main housing 11, and the telescopic shaft 29 moves downward. When the telescopic shaft 29 contacts and presses the external switch 25, the external switch 25 transmits an electrical signal through the internal and external electrical terminals, shutting off the drive assembly. After the drive assembly is shut off, the lifting assembly stops extending and retracting, and the drying rod 13 remains suspended. The external switch 25 can also be adjusted vertically on the bracket 23 to form an external adjustable limit switch, allowing external control of the lifting assembly's travel.

[0042] The advantage of this design is that conventional drive component structures typically place the internal switch 33 inside the main unit housing 11. This means that after initial adjustment, subsequent adjustments can only be made remotely, such as via a remote control or app. However, this design has the disadvantage that if the internal switch 33 malfunctions inside the housing 11, or if remote adjustment is inaccurate, the user must return the unit for repair, requiring the entire housing 11 to be disassembled for inspection, which is extremely inconvenient. By adding an external switch 25 to the outside of the housing 11, the user can directly control the travel of the lifting component by adjusting the position of the external switch 25.

[0043] Depend on Figure 8 It can be seen that both the external switch 25 and the internal switch 33 are conventional touch switches, and both are provided with extended contact plates 34 for triggering.

[0044] The main housing 11 has a frame plate 22 installed on both ends, and the lifting component and the bracket 23 are installed on both frame plates 22.

[0045] The lifting assembly is installed on the side close to the main housing 11, while the bracket 23 is installed on the side away from the main housing 11.

[0046] The vertical extension and retraction of the lifting component causes the trigger element to move vertically.

[0047] It is understood that the aforementioned frame plate 22 is a side support plate structure of the main unit housing 11. It is mainly the main structure of the main unit housing 11 and is usually an inverted "L" shaped structure. The scissor frame 12 is installed on the vertical plate, and the extension and retraction of the scissor frame 12 can slide on the frame plate 22. The bracket 23 is installed and fixed on the horizontal plate. The scissor frame 12 is located on the side closer to the main unit housing 11, and the bracket 23 is located on the side away from the main unit housing 11.

[0048] It is worth noting that a cover 30 can be detachably installed on the shelf 22. When the cover 30 is installed on the shelf 22, it surrounds and hides both the bracket 23 and the shelf 22.

[0049] The internal electrical terminal includes an internal insertion hole 27, which is installed on the frame plate 22. The electrical interface of the internal insertion hole 27 faces the outside of the main unit housing 11, and the inside of the internal insertion hole 27 is located inside the main unit housing 11 and is electrically connected to the drive assembly through a wire.

[0050] Understandably, by Figure 3 It is known that the inner insertion hole 27 is installed and fixed on the vertical plate of the frame plate 22, and the interface faces outward to facilitate the access of external electrical terminals. The wires connecting the inner insertion hole 27 include the second line 28, which extends directly into the main body housing 11 and is electrically connected to the inner switch 33.

[0051] The external electrical terminal includes an external plug 31, and the external plug 31 and the internal socket 27 are connected to switch their electrical connection / disconnection states. An electrical connector is connected between the external plug 31 and the external switch 25.

[0052] An internal switch 33 is installed on the drive assembly. The internal switch 33 is a switch element used to control the opening and closing of the drive assembly. When the internal socket 27 and the external plug 31 are in a connected state, whether the external switch 25 is triggered or not controls the opening and closing of the internal switch 33.

[0053] Understandably, by Figure 8 It is known that the external plug 31 is also connected to a first line 26, which is electrically connected to the external switch 25. The external plug 31 can be directly plugged into the internal socket 27 for power supply. When the external plug 31 and the internal socket 27 are plugged in, the external switch 25 and the internal switch 33 are powered. When the external switch 25 is triggered, the internal switch 33 is also triggered to control the motor 21 to shut down.

[0054] The adjustment groove includes a movable groove 24, which is formed on the bracket 23; the external switch 25 is slidably installed in the movable groove 24, and the sliding direction of the external switch 25 in the movable groove 24 is consistent with the extension and retraction direction of the lifting assembly.

[0055] The greater / smaller the extension range of the lifting component, the farther / closer the distance between the drying rod 13 and the main housing 11, and the greater / smaller the moving distance of the telescopic shaft 29.

[0056] It is understandable that the aforementioned movable slot 24 is a vertical through slot opened on the bracket 23. When the telescopic shaft 29 moves with the telescopic movement of the scissor frame 12, the direction is basically up and down (there is actually a slight tilt curvature). Therefore, the movable slot 24 is also a through slot opened in the vertical direction so that the external switch 25 can move in the movable slot 24.

[0057] The purpose of moving the external switch 25 is to control the maximum stroke of the scissor rack 12. Since each user's height and clothes drying habits are different, when the initial extension stroke of the scissor rack 12 causes the drying rod 13 to hang at an inconvenient height for the user, the external switch 25 can be adjusted to move up or down to control the hanging height of the drying rod 13 to a suitable height for the user.

[0058] The lifting assembly has a mounting hole 32, and the trigger includes a telescopic shaft 29, which is detachably connected to the mounting hole 32.

[0059] It is understandable that the mounting hole 32 is a threaded opening on the scissor bracket 12, and the telescopic shaft 29 can be directly threaded to the mounting hole 32 for installation. When the telescopic shaft 29 is not needed, it can also be removed by directly unscrewing the telescopic shaft 29.

[0060] The telescopic shaft 29 is foldable. When the telescopic shaft 29 is in the folded state, the movement trajectory of the telescopic shaft 29 is separated from the opening and closing contacts of the external switch 25.

[0061] It is understood that, as an alternative, when the external switch 25 or the telescopic shaft 29 is not needed, the telescopic shaft 29 can be folded so that it will not come into contact with the external switch 25 regardless of its movement. In this embodiment, as... Figure 3 As shown, the telescopic shaft 29 can be folded 90 degrees at the middle position to avoid the external switch 25. Of course, the way the telescopic shaft 29 avoids this switch includes, but is not limited to, folding, telescopic, etc.

[0062] In summary, the application scenario of this external limit switch is as follows: when the internal switch 33 malfunctions inside the main unit housing 11, or when the remote control adjustment is inaccurate, the user can only repair it by returning it to the factory and disassembling the entire main unit housing 11, which is very inconvenient. Furthermore, since each user has a different height and different habits when using the clothes drying rack, when the initial extension stroke of the scissor bracket 12 causes the drying rod 13 to hover at an inconvenient height for the user, the external switch 25 can be adjusted to move up or down to control the hanging height of the drying rod 13 to a suitable height for the user.

[0063] The method of use is as follows: The user controls the motor 21 via remote control to loosen the rope, and the drying rod 13 connected to the bottom of the rope naturally moves down by its own weight. At this time, the scissor bracket 12 slowly unfolds to provide support for the downward movement of the drying rod 13. When the drying rod 13 moves down to the predetermined position, under normal conditions, the motor 21 will trigger the internal switch 33 to control the motor 21 to turn off. If the internal switch 33 malfunctions or the remote control is inaccurate, the user can plug the internal socket 27 and the external plug 31 to energize the external switch 25 and the internal switch 33. At this time, when the drying rod 13 moves down to the predetermined position, the unfolded telescopic shaft 29 will directly contact the external switch 25 to trigger it, thereby turning off the motor 21 through the connection of the first line 26, the external plug 31, the internal socket 27, the second line 28 and the internal switch 33. The height of the trigger point can be controlled by adjusting the up and down position of the external switch 25, so that the downward movement height of the drying rod 13 is adjustable, making it convenient for the user to adapt to their own usage height.

[0064] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application.
