Description

Technical Field

[0001] The utility model relates to the technical field of clothes drying racks, in particular to an improved linkage structure for a mother-and-baby rod of a clothes drying rack. Background Art

[0002] Modern urban residents face limited balcony space, making it difficult to dry items like clothes and quilts, especially bedding. With the growing popularity of the smart home industry and people's pursuit of comfort and convenience in modern home life, clothes drying racks are becoming increasingly popular and a popular choice for drying clothes at home. To dry clothes on a balcony, simply lower the rack to the appropriate position using a hand crank and cable. Once the clothes are finished drying, the rack can be raised to the top of the balcony using the hand crank and cable again, allowing the clothes to be hung higher for optimal drying.

[0003] However, with the changes in consumer demand, in order to allow maternal and child clothes to be hung separately and meet higher hygiene requirements, an additional telescopic rack is now added to one side of the clothes drying rack, mainly used to install multiple maternal and child rods to specifically dry maternal and child clothes. The structure of a traditional clothes drying rod is as follows: when the mother and baby rod is not needed, the telescopic frame is folded and retracted to one side of the clothes drying rack column; when the mother and baby rod is needed, the telescopic frame is stretched out from one side of the clothes drying rack body, and then the mother and baby rods are installed one by one on the stretched telescopic frame. At this time, clothes can be hung on the mother and baby rod; when the mother and baby rod is used, each mother and baby rod needs to be removed from the telescopic frame one by one, and finally the telescopic frame can be folded and retracted to the clothes drying rack body again, so that the installation and removal process of the mother and baby rod on the clothes drying rack is relatively cumbersome. In order to solve this problem, some clothes drying racks currently directly install each mother and baby rod on the telescopic frame, so that the two ends of the mother and baby rod are slidably set on the telescopic tube of the telescopic frame. When in use, after the telescopic frame is stretched out from one side of the clothes drying rack body, each mother and baby rod is pulled out one by one and adjusted in position. Figure 1 As shown, during the position adjustment process, not only does the mother-and-baby pole closest to the inner edge of the telescopic rack need to be separated by a certain distance from the inner edge of the telescopic rack, but each mother-and-baby pole also needs to be separated by a certain distance to create a hanging spacing within the telescopic rack so that clothes can be hung smoothly. This is equivalent to still needing to adjust the working position of each mother-and-baby pole one by one after being pulled out, which is obviously inconvenient during the installation operation. Utility Model Content

[0005] The utility model discloses an improved linkage structure for a clothes drying rack and a mother-and-baby rod, comprising a telescopic frame for being telescopically arranged on the clothes drying rack and at least two mother-and-baby rods slidably mounted in the telescopic frame, wherein the telescopic frame comprises a telescopic tube for being telescopically arranged on the clothes drying rack; an active pull head is provided at the outer end of the telescopic tube to drive the telescopic tube to move through the active pull head, and the characteristic is that a guide rail groove is provided on one side of the telescopic tube for extending along the telescopic direction of the telescopic tube;

[0006] A plurality of driven pull heads are slidably arranged in the guide rail groove, each driven pull head passes through a notch of the guide rail groove and is respectively connected to the end of each of the mother-and-baby bars;

[0007] A plurality of pull rods are sleeved in the guide rail groove, each of the pull rods is fixedly connected to the active pull head and each of the driven pull heads, and each pull rod is provided with a barb;

[0008] A limit block is also slidably provided in the guide rail groove, and each of the pull rods extends along the length direction of the telescopic tube and passes over the limit block and is limited between the limit block and the inner wall of the guide rail groove;

[0009] It also includes a blocking structure for fixing at the end of the clothes drying rack; in the process of the active pull head pulling the telescopic tube outward and causing the various driven pull heads, various pull rods and the limit block in the guide rail groove to move outward, the blocking structure intercepts and stops the limit block that has moved a certain distance; the stopped limit block stops a pull rod by intercepting a hook that has moved a certain distance so that a driven pull head closer to the limit block stops moving; after the driven pull head closer to the limit block stops moving, it continues to intercept a pull rod by intercepting a hook that has moved a certain distance so that a driven pull head farther away from the limit block stops moving.

[0010] According to the improved linkage structure for a clothes drying rack and a baby rod of the utility model, the blocking structure includes a limiting sleeve for fixing to the end of the clothes drying rack so that the limiting sleeve is located at the starting end of the telescopic tube extending outward; the telescopic tube is slidably sleeved in the limiting sleeve;

[0011] The end of the limiting sleeve is integrally formed with a limiting buckle;

[0012] A third protrusion is integrally formed on the limiting block;

[0013] Wherein, after the telescopic tube extends outward from the end of the clothes drying rack and moves a certain distance with the third protrusion, the limit buckle intercepts and blocks the third protrusion from continuing to move outward along with the telescopic tube.

[0014] According to the improved linkage structure for a clothes drying rack and a baby rack of the utility model, the limiting sleeve is integrally formed with a storage groove extending in the length direction of the telescopic tube; the opposite ends of the storage groove are respectively provided with an opening and a baffle;

[0015] When the telescopic tube is retracted toward the clothes drying rack, each of the driven pull heads enters the receiving groove one by one through the opening, and is restricted from further movement by the baffle.

[0016] According to the improved linkage structure for a clothes drying rack and a baby bar of the utility model, a first protrusion and a second protrusion are integrally formed on opposite sides of the limit block;

[0017] The first protrusion and the second protrusion are respectively slidably engaged with the inner walls on opposite sides of the guide rail groove.

[0018] According to an improved linkage structure for a clothes drying rack mother and baby rod of the utility model, each pull rod is limited by the space between the first protrusion and the inner wall of the guide rail groove, and the space between the second protrusion and the inner wall of the guide rail groove.

[0019] According to the improved linkage structure for the mother-and-baby rod of a clothes drying rack of the utility model, the barb is integrally formed on the pull rod and protrudes in the radial direction of the pull rod.

[0020] According to the improved linkage structure for the mother-and-baby rod of a clothes drying rack of the utility model, the barb is a triangular protrusion.

[0021] According to the improved linkage structure for the mother-and-baby rod of a clothes drying rack of the utility model, each of the pull rods is a steel wire.

[0022] According to the improved linkage structure for a clothes drying rack and a baby rod of the utility model, a stop sleeve is connected to the outer surface of the telescopic tube at one end away from the active pull head;

[0023] After the telescopic tube extends outward from the clothes drying rack and moves the stop sleeve along with it for a certain distance, the limit sleeve and the stop sleeve block each other.

[0024] The utility model discloses an improved linkage structure for a clothes drying rack mother and baby pole, in addition to providing an active pull head at the outer end of the telescopic tube of the mother and baby pole, a guide rail groove is opened on one side of the telescopic tube of the mother and baby pole and a plurality of driven pull heads respectively connected to the ends of the mother and baby poles are slidably arranged in the guide rail groove, and a plurality of pull rods are provided in the guide rail groove. Specifically, each pull rod is a steel wire, the end of one pull rod is fixedly connected to the active pull head so that the pull rod can move together with the active pull head, and the ends of the other pull rods are respectively fixedly connected to the driven pull heads so that each pull rod can move together with a driven pull head. In addition, a barb is provided on each pull rod. When it is necessary to pull out the telescopic rack on the clothes drying rack, the telescopic tube is pulled outward by the active pull head. During this process, the active pull head pulls the telescopic tube outward and causes the driven pull heads, pull rods and limit blocks in the guide rail groove to move outward. When the limit block moves to the blocking structure at the end of the clothes drying rack, the blocking structure intercepts and stops the limit block that has been displaced a certain distance, and the other driven pull heads continue to move outward with the active pull head. Subsequently, the blocked limit block stops a pull rod by intercepting a barb that has been displaced a certain distance, so that a driven pull head closer to the limit block stops moving, while the other driven pull heads that have not been intercepted continue to move outward with the active pull head. At this time, the first driven pull head on the right will gradually distance itself from the second driven pull head on the right. Then, after the driven pull head closer to the limit block stops moving, it continues to stop a pull rod by intercepting a barb that has moved a certain distance, so that the adjacent driven pull head stops moving, while the other driven pull heads that have not been intercepted continue to move outward with the active pull head. At this time, the second driven pull head on the right will gradually distance itself from the third driven pull head on the right. Similarly, the originally close driven pull heads can eventually be distanced from each other, and the mother and baby rods that are pulled out can be separated by a certain distance, which makes it easier to build the hanging spacing of the mother and baby rods in the telescopic frame, and realize the quick and easy installation of the mother and baby rods on the clothes drying rack. In other words, during operation, as long as the telescopic frame and telescopic tube on the side of the clothes drying rack are pulled outward, the mother and baby rods can be pulled out one by one quickly and easily, so that the mother and baby rods that are pulled out can be separated by a certain distance, which makes it easier to build the hanging spacing of the mother and baby rods in the telescopic frame, and realize the quick and easy installation of the mother and baby rods on the clothes drying rack. In addition, since a limit block is slidably provided in the guide rail groove, each pull rod extends along the length direction of the telescopic tube and passes over the limit block and is limited between the limit block and the inner wall of the guide rail groove. Therefore, it can be ensured that each pull rod extending along the telescopic tube can be restricted in the guide rail groove, preventing the pull rod from falling out of the telescopic tube during assembly and use.

[0053] like Figures 2 to 14As shown, the present embodiment is an improved linkage structure for a clothes drying rack and a mother-and-baby pole, the structure of which includes a telescopic frame 1 that is telescopically mounted on the clothes drying rack, a plurality of mother-and-baby poles 2 being slidably mounted within the telescopic frame 1, and a telescopic tube 3 that is telescopically sleeved within the clothes drying rack rod 10. Specifically, the clothes drying rack includes a fixed clothes drying rack rod 10, and the telescopic tube 3 is slidably sleeved within the inner cavity of the clothes drying rack rod 10, so that the telescopic tube 3 can be telescopically moved within the inner cavity of the clothes drying rack rod 10. An active pull head 4 is fixed to the outer end of the telescopic tube 3, and during operation, the active pull head 4 can drive the telescopic tube 3 to telescopically move left and right. In addition, a guide rail groove 5 is opened on the inner side of the telescopic tube 3, and the guide rail groove 5 extends along the telescopic direction of the telescopic tube 3. A plurality of driven pull heads 6 are slidably arranged within the guide rail groove 5, and each driven pull head 6 passes through the notch of the guide rail groove 5 and is respectively connected to the end of each mother-and-baby pole 2. A plurality of pull rods 7 are also sleeved within the guide rail groove 5. Each pull rod 7 is a steel wire. Each pull rod 7 extends along the length of the telescopic tube 3 and is fixedly connected to the active pull head 4 and each driven pull head 6. Specifically, in this embodiment, the end of one of the pull rods 7 is fixedly connected to the active pull head 4 so that it can move together with the active pull head 4, while the ends of the other pull rods 7 are fixedly connected to each driven pull head 6 so that each pull rod 7 can move together with each driven pull head 6. Each pull rod 7 is provided with a barb 8. Specifically, the barb 8 is integrally formed on the pull rod 7 and protrudes in the radial direction of the pull rod 7. The barb 8 is a triangular protrusion. In addition, a limit block 11 is slidably assembled within the guide rail groove 5. Each pull rod 7 extends along the length of the telescopic tube 3 and passes over the limit block 11 and is limited between the limit block 11 and the inner wall of the guide rail groove 5. In addition, it also includes a blocking structure for fixing to the end of the clothes drying rack. When in operation, the active pull head 4 is used to pull the telescopic tube 3 outward (ie, Figure 3 In the process of the telescopic tube 3 shown in the coordinates extending to the left) and the driven pull heads 6, the pull rods 7 and the limit blocks 11 in the guide rail groove 5 moving outward, the blocking structure intercepts and stops the limit block 11 that has moved a certain distance. Subsequently, the stopped limit block 11 intercepts a barb 8 that has moved a certain distance to stop a pull rod 7 so that a driven pull head 6 closer to the limit block 11 (i.e., as shown in the attached figure) is moved outward. Figure 9 The first driven pull head 6 from the right side of the middle stops displacement, and then the driven pull head 6 closer to the limit block 11 (i.e., as shown in the attached Figure 9 After the first driven pull head 6 from the right side stops moving, it continues to stop a pull rod 7 by intercepting a barb 8 that has moved a certain distance so that an adjacent driven pull head 6 (i.e., as shown in the attached Figure 9 The second driven pull head 6 from the right in the middle stops moving, and so on, the other adjacent barbs 8 will also be intercepted by the other driven pull heads 6 after moving a certain stroke.

[0054] It can be understood that in addition to providing an active pull head 4 at the outer end of the telescopic tube 3 of the mother and baby rod, a mother and baby rod linkage structure of this embodiment also opens a guide rail groove 5 on one side of the telescopic tube 3 of the mother and baby rod and slides a plurality of driven pull heads 6 respectively connected to the ends of each mother and baby rod 2 in the guide rail groove 5, and a plurality of pull rods 7 are provided in the guide rail groove 5. Specifically, each pull rod 7 is a steel wire, and the end of one pull rod 7 is fixedly connected to the active pull head 4 so that the pull rod 7 can move together with the active pull head 4, while the ends of the other pull rods 7 are respectively fixedly connected to the driven pull heads 6 so that each pull rod 7 can move together with a driven pull head 6. In addition, a barb 8 is provided on each pull rod 7. When it is necessary to pull out the telescopic rack 1 on the clothes drying rack, the telescopic tube 3 is extended outward by the active pull head 4. During this process, the active pull head 4 pulls the telescopic tube 3 outward and causes the various driven pull heads 6, the pull rods 7 and the limit blocks 11 in the guide rail groove 5 to move outward. When the limit block 11 moves to the blocking structure at the end of the clothes drying rack, the blocking structure intercepts and stops the limit block 11 that has been displaced a certain stroke, and the other driven pull heads 6 continue to move outward with the active pull head 4. Subsequently, the blocked limit block 11 intercepts a barb 8 that has been displaced a certain stroke to stop a pull rod 7 so that a driven pull head 6 that is closer to the limit block 11 (i.e., as shown in the attached figure) is moved outward. Figure 9 The first driven pull head 6 on the right side of the middle part stops moving, while the other driven pull heads 6 that are not blocked continue to move outward with the active pull head 4. At this time, the first driven pull head 6 on the right side gradually distances itself from the second driven pull head 6 on the right side. Figure 9 After the first driven pull head 6 from the right side stops moving, it continues to stop a pull rod 7 by intercepting a barb 8 that has moved a certain distance so that an adjacent driven pull head 6 (i.e., as shown in the attached Figure 9The second driven pull head 6 from the right side stops moving, while the other driven pull heads 6 that are not blocked continue to move outward with the active pull head 4. At this time, the second driven pull head 6 on the right side will gradually distance itself from the third driven pull head 6 on the right side. Similarly, the originally close driven pull heads 6 can eventually be distanced from each other, and then the mother-and-baby rods 2 that are pulled out can be spaced a certain distance apart, which makes it easier to build the hanging spacing of the mother-and-baby rods in the telescopic frame, and realize the quick and easy installation of the mother-and-baby rods on the clothes drying rack. In other words, during operation, as long as the telescopic frame 1 and the telescopic tube 3 on the side of the clothes drying rack are pulled outward, the mother-and-baby rods 2 can be pulled out one by one quickly and easily, so that the mother-and-baby rods 2 that are pulled out can be spaced a certain distance apart, which makes it easier to build the hanging spacing of the mother-and-baby rods in the telescopic frame, and realize the quick and easy installation of the mother-and-baby rods on the clothes drying rack. In addition, since a limit block 11 is slidably provided in the guide rail groove 5, each pull rod 7 extends along the length direction of the telescopic tube 3 and passes over the limit block 11 and is limited between the limit block 11 and the inner wall of the guide rail groove 5. Therefore, it can be ensured that each pull rod 7 extending along the telescopic tube 3 can be restricted in the guide rail groove 5, preventing the pull rod 7 from falling out of the telescopic tube 3 during assembly and use.

[0055] In one embodiment, combined Figure 11 、 Figure 12 、 Figure 13 、 Figure 14 As shown in the accompanying drawings, the blocking structure includes a stopper sleeve 9, which is fixed to the end of the clothes drying rack so that the stopper sleeve 9 is located at the starting end of the extension of the telescopic tube 3. The telescopic tube 3 is slidably connected within the stopper sleeve 9. The end of the stopper sleeve 9 is integrally formed with a stopper buckle 91, and the stopper block 11 is integrally formed with a third protrusion 113. After the telescopic tube 3 extends outward from the end of the clothes drying rack and moves a certain distance with the third protrusion 113, the stopper buckle 91 intercepts and prevents the third protrusion 113 from continuing to move outward with the telescopic tube 3. Therefore, when the active puller 4 pulls the telescopic tube 3 outward, the stopper block 11 stops moving outward with the telescopic tube 3 after a certain distance. The stopper buckle 91 of the stopper sleeve 9 intercepts the third protrusion 113 and stops it from continuing to move outward with the telescopic tube 3. Subsequently, the first driven puller 6 on the right and the mother-and-baby bar 2 can be smoothly opened.

[0056] Further, combined with Figure 11 、 Figure 12 and Figure 13As shown in other corresponding figures, the limiting sleeve 9 is integrally formed with a receiving groove 92, which extends in the length direction of the telescopic tube 3. The left and right ends of the receiving groove 92 are respectively provided with an opening 93 and a baffle 94. Each driven pull head 6 can enter the receiving groove 92 to the right through the opening 93. The baffle 94 is located at the rightmost end of the receiving groove 92, so the baffle 94 can limit the continued movement of each driven pull head 6. When the telescopic tube 3 is retracted in the direction of the clothes drying rack, each driven pull head 6 enters the receiving groove 92 one by one through the opening 93. After that, the baffle 94 limits the continued movement of each driven pull head 6. At this time, each driven pull head 6 entering the receiving groove 92 can be relocated in the receiving groove 92, and finally the mother and baby bars 2 are also relocated to each other and arranged side by side, completing the retracted state of the mother and baby bar telescopic rack simply and conveniently.

[0057] In one embodiment, the upper and lower sides of the limit block 11 are respectively integrally formed with a first protrusion 111 and a second protrusion 112. When the limit block 11 is assembled inside the guide rail groove 5, the first protrusion 111 and the second protrusion 112 are respectively slidably engaged with the upper and lower inner walls of the guide rail groove 5, thereby ensuring that the limit block 11 will not fall out of the notch of the guide rail groove 5. In addition, the space between the first protrusion 111 and the inner wall of the guide rail groove 5 and the space between the second protrusion 112 and the inner wall of the guide rail groove 5 respectively limit the position of each pull rod 7, thereby ensuring that each pull rod 7 can be confined within the guide rail groove 5, preventing the pull rod 7 from falling out of the telescopic tube 3 during assembly and use.

[0058] In one embodiment, a stop sleeve (not shown) is connected to the outer portion of the telescopic tube 3 at one end away from the active pull head 4. After the telescopic tube 3 extends outward from the clothes drying rack and moves a certain distance with the stop sleeve, the limit sleeve 9 and the stop sleeve block each other. Therefore, under the restriction of the stop sleeve, the telescopic tube 3 can be prevented from completely separating from the clothes drying rack rod 10, ensuring that the telescopic tube 3 will not completely separate from the clothes drying rack.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
