Description

Technical Field

[0001] The present invention relates to the technical field of electric clothes drying racks, and in particular to a modular electric winding drum for clothes drying racks. Background Art

[0002] Traditional clothes drying racks are suspended from the ceiling, requiring a clothesline to be placed on the rack. This is extremely inconvenient. Therefore, there is a need for electric clothes drying racks that automatically move up and down for easier use. To address these issues, electric lift clothes drying racks installed on balconies have gained widespread acceptance in recent years for their convenience and practicality. These electric clothes drying racks operate by using a motor to drive a rotating shaft, which retracts and extends the rope. However, if the rope is pushed or collided by external forces, the motor often needs to be stopped to ensure safety.

[0003] Existing electric clothes drying machines, such as the one disclosed in Chinese Patent (Granted Publication No. CN209226252U), include a reel for an electric clothes drying rack, comprising a motor, a dual reducer, a housing, a rope, and a junction box. The motor is connected to the dual reducer through a transmission connection, and the rope passes through the dual reducer. A control device is provided in the junction box, and the housing is provided with a resistance rebound mechanism. The resistance rebound mechanism includes a movable seat, an elastic reset element, and a micro switch. The housing is provided with a sliding channel. The rope passes through one end of the movable seat, and the other end of the movable seat extends into the sliding channel. The elastic reset element is located in the sliding channel and abuts against the movable seat. The micro switch is mounted on the housing, and the movable seat has a tendency to move toward the micro switch under the action of the elastic reset element. The micro switch is connected to the control device in the junction box. At the same time, in order to control the up and down travel of the clothes drying rack (i.e., controlling the highest and lowest positions of the clothes drying rack), its two worm gears are connected to two adjustment gears through respective gear sets. The two adjustment gears are respectively connected to a first adjustment block and a second adjustment block. The housing is provided with a first travel switch that cooperates with the first adjustment block and a second travel switch that cooperates with the second adjustment block.

[0004] However, the above-mentioned clothes drying rack has the following disadvantages:

[0005] 1. The micro switches corresponding to the resistance rebound mechanism and the micro switches corresponding to the travel mechanism are both exposed and installed on the outside of the main body shell. On the one hand, the micro switches are easily damaged by collisions. On the other hand, the micro switches are installed on the outside of the main body, which makes the overall appearance of the product unsightly.

[0006] 2. Because the micro switch is exposed on the housing of the main unit, the connecting wires to the micro switch need to be led out of the electric control box, making the assembly of the connecting wires more complicated. Moreover, since the electric cable reel needs to be packaged and transported after the connecting wires are connected, the electric cable reel can only be packaged and transported as a whole, and the main unit and the electric control box cannot be packaged and transported separately, resulting in high packaging and transportation costs.

[0007] 3. The main unit and the electric control box are connected by screws, which makes the assembly and disassembly of the main unit and the electric control box more complicated, which leads to troublesome early assembly and later maintenance and disassembly. Summary of the Invention

[0008] The purpose of the present invention is to provide a modular electric reel for clothes drying rack, in which the first microswitch and the second microswitch are integrated into the electric control box, which can effectively protect the first microswitch and the second microswitch. The connecting wire is set in the electric control box, which can facilitate the disassembly and assembly of the main unit and the electric control box. At the same time, the main unit and the electric control box are independently set, and the main unit and the electric control box can be independently packaged and transported, which greatly reduces the packaging box transportation cost.

[0013] Furthermore, the elastic latch includes an elastic rib connected to the second turntable and a tooth portion connected to the elastic rib and meshing with the tooth groove. A slot passing through the second turntable is provided between the elastic rib and the second turntable, so that the elastic latch can be extended and retracted relative to the second turntable to clamp the tooth groove or disengage from the tooth groove.

[0014] Furthermore, the travel mechanism includes an upper travel mechanism corresponding to one of the second micro switches and a lower travel mechanism corresponding to the other second micro switch, the upper travel mechanism is used to limit the highest upward position of the clothes drying rack, and the lower travel mechanism is used to limit the lowest downward position of the clothes drying rack.

[0015] Furthermore, the frame is provided with a first slot, and the electrical control box is provided with a first plug-in block, which limits the electrical control box from moving relative to the frame along a direction perpendicular to the insertion direction of the first plug-in block through the plug-in cooperation between the first slot and the first plug-in block.

DETAILED DESCRIPTION

[0037] The present invention will be further described below with reference to the accompanying drawings.

[0038] like Figure 1-8 As shown, a modular electric reel 12 for clothes drying rack includes a main unit 1 and an electric control box 2 detachably connected to the main unit 1, the main unit 1 includes a frame 11, two reels 12 rotatably arranged on the frame 11, and a power assembly 13 for driving the two reels 12 to rotate synchronously. Specifically, the power assembly 13 includes a motor 131 and a gear set 132 symmetrically arranged on both sides of the output shaft of the motor 131, a transmission gear 122 is provided on the rotating shaft 121 of the reel 12, which is transmission-connected to the gear set 132, a rope is wound around the reel 12, and an obstruction rebounder 14 corresponding to the reel 12 is provided on the frame 11, the rope passes through the obstruction rebounder 14 and is connected to the clothes drying rack, and the above constitutes the basic structure of the electric reel 12.

[0039] The resistance rebounder 14 can slide vertically in the frame 11, and the electric control box 2 is provided with a first micro switch 21 corresponding to the resistance rebounder 14. The frame 11 is provided with a push rod 15 which slides vertically synchronously with the resistance rebounder 14. The electric control box 2 is provided with a channel 23 for the push rod 15 to extend into. Under the action of the resistance rebounder 14, the push rod 15 can extend into the electric control box 2 and trigger the first micro switch 21. The frame 11 is provided with an elastic member that drives the resistance rebounder 14 to move toward the electric control box 2, that is, the resistance rebounder 14 has a tendency to move toward the first micro switch 21 under the action of the elastic member. In the present invention, the elastic member can be a spring that pushes the resistance rebounder 14 upward or a tension spring that pulls the resistance rebounder 14 upward.

[0040] The frame 11 is also provided with a stroke mechanism 16 corresponding to the winding drum 12 one by one, and the electric control box 2 is provided with a second micro switch 22 corresponding to the stroke mechanism 16. The center of the winding drum 12 is provided with a rotating shaft 121. The stroke mechanism 16 includes a first turntable 161 rotatably connected to the frame 11 and transmission-connected to the rotating shaft 121. The peripheral wall of the first turntable 161 is provided with a protrusion 1611. The electric control box 2 is provided with an opening facing the first turntable 161 on the side for the protrusion 1611 to enter the electric control box 2. The protrusion 1611 can enter the electric control box 2 driven by the first turntable 161 and trigger and cooperate with the second micro switch 22.

[0041] The first microswitch 21 and the second microswitch 22 are integrated into the electric control box 2, and the connecting wires of the first microswitch 21 and the second microswitch 22 are set in the electric control box 2, so that the electric reel 12 is divided into only two modules, the main unit 1 and the electric control box 2. On the one hand, it can protect the first microswitch 21 and the second microswitch 22 hiddenly installed in the electric control box 2. On the other hand, the main unit 1 and the electric control box 2 can be independently manufactured and produced, and then the main unit 1 and the electric control box 2 can be independently packaged and transported, which greatly reduces the packaging and transportation costs.

[0042] The stroke mechanism 16 includes an upper stroke mechanism 16 corresponding to one of the second micro switches 22 and a lower stroke mechanism 16 corresponding to the other second micro switch 22. The upper stroke mechanism 16 is used to limit the highest upward position of the clothes drying rack, and the lower stroke mechanism 16 is used to limit the lowest downward position of the clothes drying rack. Specifically, the upper stroke switch and the lower stroke switch have the same structure, only the initial position of the protrusion 1611 is different. When the clothes drying rod moves down to the set lowest point, the protrusion 1611 of the lower stroke mechanism 16 rotates to abut against the corresponding second micro switch 22, thereby triggering the corresponding second micro switch 22, causing the motor 131 to stop running. When the clothes drying rod moves up to the set highest point, the protrusion 1611 of the upper stroke mechanism 16 rotates to abut against the corresponding second micro switch 22, thereby triggering the corresponding second micro switch 22, causing the motor 131 to stop running.

[0043] The frame 11 is provided with an adjustment structure for adjusting the rotation stroke of the first turntable 161, and the adjustment structure includes a second turntable 162 arranged in the first turntable 161, and the second turntable 162 is connected to the rotating shaft 121 in a transmission manner. Specifically, the inner ring of the second turntable 162 is provided with an inner gear ring, and the rotating shaft 121 is provided with a gear meshing with the inner gear ring. The second turntable 162 is provided with an elastic latch 1621, and the inner ring of the first turntable 161 is circumferentially provided with a tooth groove 1612. The second turntable 162 is connected to the tooth groove 1612 through the elastic latch 1621. The 12-bit snap fit drives the first turntable 161 to rotate synchronously, and the elastic latch teeth 1621 can be extended and retracted relative to the second turntable 162 so that the first turntable 161 can rotate relative to the second turntable 162. The rotation stroke of the first turntable 161 is adjusted by rotating the first turntable 161 relative to the second turntable 162, that is, the angle of rotation of the first turntable 161 from the initial position to the trigger position (the position when the protrusion 1611 triggers the second micro switch 22) is adjusted, thereby adjusting the highest position of the upper travel switch or the lowest position of the lower travel switch.

[0044] In the present invention, the elastic latch 1621 includes an elastic rib 1622 connected to the second turntable 162 and a tooth portion 1623 connected to the elastic rib 1622 and meshing with the tooth groove 1612. A slot 1624 is provided between the elastic rib 1622 and the second turntable 162, which passes through the second turntable 162, so that the elastic latch 1621 can be extended and retracted relative to the second turntable 162 to clamp the tooth groove 1612 or disengage from the tooth groove 1612. There are multiple elastic latches 1621 and they are circumferentially distributed on the outer circumference of the second turntable 162. This structural arrangement makes the clamping effect of the first turntable 161 and the second turntable 162 better, and the stability of the first turntable 161 and the second turntable 162 when rotating synchronously is higher.

[0045] When the electric cord reel is in normal operation, the power assembly 13 drives the second turntable 162 to rotate, and the second turntable 162 drives the first turntable 161 to rotate synchronously, so that the protrusion 1611 rotates from the initial position to the trigger position (the position when the protrusion 1611 triggers the second microswitch 22). When the protrusion 1611 triggers the second microswitch 22, the driving assembly stops working, so that the clothes dryer stops moving up or down. When the electric cord reel is in the non-working state, the power assembly 13 is in a stopped state, and the second turntable 162 is also in a stopped state. By rotating the first turntable 161, the elastic latch 1621 of the second turntable 162 is squeezed inward by the tooth groove 1612 to disengage the tooth portion from the tooth groove 1612. At this time, the first turntable 161 can rotate relative to the second turntable 162, and then the protrusion 1611 on the first turntable 161 can be rotated to the desired position to adjust the highest position of the upper travel switch and the lowest position of the lower travel switch.

[0046] The second turntable 162 is provided with a scale 165 at one end adjacent to the first turntable 161, and a through slot 1613 is provided on the end face of the first turntable 161. The scale 165 on the second turntable 162 can be observed through the through slot 1613. Through this arrangement, adjusting the relative position of the first turntable 161 and the second turntable 162 is more intuitive, making adjustment more convenient.

[0047] The electric control box 2 is buckled with the frame 11. Specifically, the frame 11 is provided with a first slot 111, and the electric control box 2 is provided with a first plug-in block 24. The first slot 111 is engaged with the first plug-in block 24 to limit the movement of the electric control box 2 relative to the frame 11 along the insertion direction perpendicular to the first plug-in block 24. In the present invention, there are two first plug-in blocks 24 and they are symmetrically arranged on the electric control box 2. The first slot 111 is corresponding to the first plug-in block 24. The first plug-in block 24 has a block structure with a small upper part and a large lower part. The shape of the groove 111 is adapted to the first plug-in block 24. A fixing plate 3 is provided on the side of the electric control box 2 corresponding to the first plug-in block 24. The electric control box 2 is provided with a receiving groove 25 for accommodating the fixing plate 3. The lower part of the fixing plate 3 is provided with an elastic support foot 31 that abuts against the frame 11. The fixing plate 3 abuts against the inner end of the receiving groove 25 through the elastic support foot 31. Under the elastic force of the elastic support foot 31, the electric control box 2 is tightly abutted against the inner end of the first slot 111 to limit the movement of the electric control box 2 relative to the frame 11 along the insertion direction of the first plug-in block 24.

[0048] An upwardly extending limit strip 33 is provided at the upper inner end of the fixing plate 3. The limit strip 33 extends into the electric control box 2 and cooperates with the inner wall of the electric control box 2 to fix the fixing plate 33 on the electric control box 2. There are two limit strips 33 and they are arranged at intervals.

[0049] A second plug-in block 32 is provided at the lower portion of the fixing plate 3 and / or the elastic support leg 31, and the electric control box 2 is provided with a second slot 117 for inserting the second plug-in block 32. The second plug-in block 32 is engaged with the second slot 117 to limit the fixing plate 3 on the frame 11. At the same time, the elastic force exerted by the elastic support leg 31 on the frame 11 firmly confines the second plug-in block 32 in the second slot 117, thereby preventing the fixing plate 3 from falling off the frame 11.

[0050] The lower end surface of the electric control box 2 is provided with a hook portion 26, and the upper end surface of the frame 11 is provided with a socket 112 for inserting the hook portion 26. The vertical movement of the electric control box 2 relative to the frame 11 is limited by the plug-in cooperation of the hook portion 26 and the socket 112. The hook portion 26 extends into the socket 112 and the upper end surface of the hook portion 26 is limited by the upper end surface of the frame 11 to vertically limit the electric control box 2 and the frame 11. In the present invention, there are two barb portions 26 and they are arranged at an interval at the lower end of the electric control box 2. The socket 112 and the barb portions 26 are arranged corresponding to the barb portions 26. The card-mounted connection structure of the host 1 and the electric control box 2 is more convenient in early assembly and later maintenance and disassembly than the screw connection structure.

[0051] The frame 11 is provided with a first slide 113 that slides with the push rod 15. The position of the electric control box 2 corresponding to the first slide 113 is provided with a channel 23 for the push rod 15 to extend into the electric control box 2. When encountering resistance, the push rod 15 is vertically raised and lowered under the action of the rebounder 14 to trigger or disconnect the first micro switch 21.

[0052] The frame 11 is provided with an upper limit portion 114 for limiting the uppermost position of the resistance rebounder 14 and a lower limit portion 115 for limiting the lowermost position of the resistance rebounder 14. This structure is used to mechanically limit the upper and lower strokes of the resistance rebounder 14, and can ensure that the stroke of the resistance rebounder 14 is limited when the second micro switch 22 fails to work normally.

[0053] The host 1 is provided with a mounting column, on which a fastener 163 is provided. The first turntable 161 and the second turntable 162 are rotatably set on the mounting column through the fastener 163. The inner end of the fastener 163 is provided with an elastic foot 1631, and the frame 11 is provided with a step hole 116 that is engaged with the elastic foot 1631. The outer end of the fastener 163 is provided with a limiting ring 1632 that prevents the first turntable 161 from sliding out of the fastener 163. The structural design of the fastener 163 and the step hole 116 can facilitate the assembly of the first turntable 161 and the second turntable on the frame 11.

[0054] The above description is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
