Description

Technical Field

[0001] This utility model belongs to the field of clothes drying racks, and more specifically, it relates to a pre-tightening force adjustment system for the clothes drying rack's drying component. Background Technology

[0002] Currently, clothes drying racks on the market usually require accessories such as clips and baby clips to dry small items of clothing, such as baby clothes. When there are many small items, it is necessary to repeatedly clamp or retrieve them, which makes the drying process time-consuming and the experience poor.

[0003] For example, utility model patent publication number "CN221778151U" discloses "a drying net assembly and a clothes drying machine. The drying net assembly of this utility model includes a drying net box, a first winding mechanism, a drying net, a pulling rod, and a supporting structure. The first winding mechanism is rotatably connected to the drying net box. The front end of the drying net is wound around the first winding mechanism, and the rear end of the drying net is connected to the pulling rod. The supporting structure is located below the drying net. The clothes drying machine of this utility model includes a main unit, a drying assembly, and a drying net assembly. The drying assembly is connected below the main unit and includes a drying rod and two end caps. The two end caps are respectively located at both ends of the drying rod, and the end caps have receiving cavities. The drying net assembly is placed in the receiving cavities..."

[0004] The existing technology has the following drawbacks: traditional clothes drying racks typically use a fixed tension structure for the drying net assembly, lacking an effective elastic force adjustment and compensation mechanism. This leads to common problems during long-term use, such as the drying net slackening and sagging, inconsistent tension during pull-out / retraction, and a poor user experience. Consequently, it cannot adapt to different load-bearing requirements, affecting the product's aesthetics, ease of use, and lifespan. Therefore, a clothes drying rack drying assembly pre-tension adjustment system is provided to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a pre-tightening force adjustment system for the drying rack assembly, which can make the preload of the elastic element adjustable, thereby greatly improving the service life of the drying rack assembly.

[0006] This utility model discloses a pre-tightening force adjustment system for a clothes drying rack assembly, comprising,

[0007] The main unit has two drying rods at its bottom, and rod holders are installed between the two drying rods. There are two rod holders, which are located directly below both ends of the main unit.

[0008] A drying assembly is installed with the pole base. The drying assembly includes a winding mechanism on which a mesh fabric is installed. The winding mechanism generates a control force on the mesh fabric to control the unfolding and retraction of the mesh fabric.

[0009] The drying assembly also includes a pre-tightening mechanism, which is installed and configured with the winding mechanism to directly adjust the control force of the winding mechanism on the movement of the mesh fabric.

[0010] As a further improvement of this utility model, the drying assembly includes a mesh box, the mesh box is installed with the rod base, the winding mechanism is installed at one end of the mesh box, and the pre-tightening mechanism is installed at the end position of the mesh box and the winding mechanism on the same side.

[0011] The mesh box is open at both ends and has a strip-shaped opening on one end face. One end of the mesh box is sealed by a cover and the other end is sealed by a winding mechanism. The mesh body can be unfolded and stored through the strip-shaped opening on the end face.

[0012] As a further improvement of this utility model, the winding mechanism includes a support shaft, and the mesh fabric is wound around the support shaft.

[0013] A connecting member is also installed at one end of the support shaft, and the connecting member is installed with the winding mechanism.

[0014] As a further improvement of this utility model, the docking component includes a docking post, one end of which is provided with a protruding insert, and the other end of which is provided with a through pipe.

[0015] The insert is configured to be inserted into and fitted with the support shaft.

[0016] As a further improvement of this utility model, the winding mechanism further includes a mounting box, which is installed at the end of the mesh box. The mounting box has a receiving cavity, and a sheet spring is installed in the receiving cavity. The connecting piece is installed with the axial end of the sheet spring.

[0017] As a further improvement of this utility model, the axial end of the coil spring includes an inner flat plate, which is inserted into and fitted with the through pipe.

[0021] As a further improvement of this utility model, when the mesh fabric is in the stored state, the coil spring is in a first state; when the mesh fabric is gradually unfolded, the coil spring gradually switches from the first state to the second state.

[0022] The change in the vertical position of the outer flat plate alters the tension level in the first state.

[0023] Compared with the prior art, the advantages of this utility model are as follows: This patent is equipped with an adjustable elastic pre-tightening mechanism, which realizes flexible control and adjustment of the pre-tightening force of the elastic element in the drying net, thereby solving the problem of slack and sagging and incomplete retraction of the drying net during long-term use.

[0034] 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.

[0035] Specific Implementation Example 1: Please refer to Figure 1-8 A clothes drying rack drying assembly pre-tightening force adjustment system includes a main unit 11, with two drying rods 12 arranged below it, and a rod seat 13 installed between the two drying rods 12. There are two rod seats 13, which are respectively located directly below the two ends of the main unit 11.

[0036] A drying assembly is installed on the pole base 13. The drying assembly includes a winding mechanism, on which a mesh fabric 22 is installed. The winding mechanism generates a control force on the mesh fabric 22 to control the unfolding and retraction of the mesh fabric 22.

[0037] The drying assembly also includes a pre-tightening mechanism, which is installed and configured with the winding mechanism to directly adjust the control force of the winding mechanism on the movement of the mesh fabric 22.

[0038] It is understandable that, such as Figure 1As shown, the main unit 11 is installed and fixed to the indoor ceiling. It contains an electric drive component such as a motor and controller, as well as conventional structures such as lighting components. Two drying rods 12 are suspended below the main unit 11 and are raised and lowered via steel wire ropes and scissor frames. Each of the two drying rods 12 has a telescopic rod 14, which can extend and retract along its length. A mesh box 21 is installed at each end of the two telescopic rods 14; in use, the telescopic rod 14 can extend or retract by pulling the mesh box 21. Similarly, two rod seats 13 are provided between the two drying rods 12. The rod seats 13 connect the two drying rods 12 and also support the steel wire ropes and scissor frames, thus achieving the connection between the main unit 11 and the drying rods 12.

[0039] It needs to be further explained that, such as Figure 1 As shown, the aforementioned drying assembly is installed on the pole base 13, and its internal winding mechanism is connected to the mesh fabric 22. The winding mechanism includes an elastic element, which controls the extension and retraction of the mesh fabric 22 through its elastic force. When the mesh fabric 22 extends, it can be pulled towards the mesh fabric box 21 and then fixed to the mesh fabric box 21. At this time, small items of clothing can be placed on the mesh fabric 22 for drying.

[0040] It should be further explained that a handle 23 is also fixedly provided at one end of the mesh body 22. The handle 23 is located on the outside of 21 and cannot be completely stored in the mesh box 21. The handle 23 can be fixed to the rod seat 13 to maintain the extended state of the mesh body 22.

[0041] It should be further explained that the pre-tightening mechanism is directly connected to the aforementioned elastic element, and the preload of the elastic element can be adjusted, thereby adjusting the control force of the extension and retraction movement of the mesh fabric 22.

[0042] The advantage of setting up this pre-tightening mechanism is that when the elastic element is used for a long time, the elastic force tends to gradually weaken. Therefore, when the mesh body 22 and the mesh box 21 are separated from the fixed, the elastic force of the elastic element cannot drive the mesh body 22 to roll up and store, and thus the mesh body 22 cannot be fully retracted into the winding mechanism, which greatly affects the aesthetics.

[0043] The advantage of setting up this pre-tightening mechanism is that, after prolonged use, the elasticity of the elastic element tends to gradually weaken. Therefore, when the mesh fabric 22 is unfolded, it may be in a loose state. When clothes are placed in a loose state for drying, they may fall off and get dirty, which greatly affects the user experience. Therefore, by adjusting the preload of the elastic element through the pre-tightening mechanism, the unfolded mesh fabric 22 can be tightened again, thereby improving the service life of the mesh fabric 22.

[0044] The drying assembly includes a mesh box 21, which is installed with the rod base 13. The winding mechanism is installed at one end of the mesh box 21, and the pre-tightening mechanism is installed at the end of the mesh box 21 on the same side as the winding mechanism.

[0045] The mesh box 21 is open at both ends and has a strip-shaped opening on one end face. One end of the mesh box 21 is sealed by a cover and the other end is sealed by a winding mechanism. The mesh body 22 is unfolded and stored through the strip-shaped opening on the end face.

[0046] It is understood that the aforementioned mesh box 21 is a box used to install the mesh body 22 and related winding and pre-tightening mechanisms. Therefore, it is open on both sides and has a strip-shaped opening 28 to provide space and guidance for the expansion and contraction of the mesh body 22. One end of the mesh box 21 is provided with a cap 25 to seal one end, while the other end is sealed by the mounting box 32.

[0047] The winding mechanism includes a support shaft 26, and the mesh fabric 22 is wound around the support shaft 26.

[0048] A docking component is also installed at one end of the support shaft 26, and the docking component is installed with the winding mechanism.

[0049] It is understandable that the aforementioned support shaft 26 is a support component. After one side of the mesh fabric 22 is fixed to the support shaft 26, it is then wrapped around the support shaft 26 one circle at a time. When the mesh fabric 22 extends, the support shaft 26 rotates synchronously. The elastic element drives the support shaft 26 to reverse and then the mesh fabric 22 is wrapped and stored.

[0050] The docking component includes a docking post 29, one end of which is provided with a protruding insert 46, and the other end of which is provided with a through pipe 30.

[0051] The insert 46 is inserted into and engaged with the support shaft 26.

[0052] It is understood that the aforementioned mating components include a mating post 29, with an insert 46 provided on one end face of the mating post 29. The outer circumference of the insert 46 has a protrusion, and the end of the support shaft 26 near the mating post 29 has a socket 27. Therefore, the socket 27 and the insert 46 can form a plug-in fit. A through pipe 30 is provided on the other end face of the mating post 29, and a second socket 31 is provided on the through pipe 30.

[0053] The winding mechanism further includes a mounting box 32, which is installed at the end of the mesh box 21. The mounting box 32 has a receiving cavity 34, within which a leaf spring 35 is installed. The connecting piece is installed with the axial end of the leaf spring 35. The axial end of the leaf spring 35 includes an inner flat plate 37, which is inserted into and cooperates with the through tube 30.

[0054] It is understood that the aforementioned mounting box 32 serves both as a cover for sealing the end of the mesh box 21 and as a container for housing the elastic element. The mounting box 32 has a receiving cavity 34, and the elastic element includes a leaf spring 35, which is installed within the receiving cavity 34. The axial end of the leaf spring 35 includes a straight inner flat plate 37, which can extend into the insertion port 31 to form a plug-in fit.

[0055] It should be further noted that the aforementioned leaf spring 35 is a spring steel structure, and its material properties are similar to those of the iron core in the measuring tape.

[0056] It should be further explained that the mounting box 32 is provided with screw holes 41, and the end of the mesh box 21 is also provided with corresponding holes. The mounting box 32 can be directly fixed on the mesh box 21 by passing screws 40 through screw holes 41.

[0057] The mounting box 32 is provided with a mounting platform 42, and the pre-tightening mechanism is mounted on the mounting platform 42. The pre-tightening mechanism is mounted to the outer circular end of the leaf spring 35. The pre-tightening mechanism includes a transmission column 39, which is movably connected to the mounting platform 42. The outer circular end of the leaf spring 35 includes an outer flat plate 36, on which a moving block 45 is mounted. One end of the transmission column 39 is mounted to the moving block 45.

[0058] It is understood that the mounting platform 42 is hollowed out to form a transmission cavity 43, and a transmission block 38 is installed in the transmission cavity 43. The transmission column 39 passes through the mounting platform 42 and forms a direct threaded connection with the transmission block 38. Therefore, when the transmission column 39 rotates, it can move in the vertical direction through the threaded connection with the transmission block 38.

[0059] It should be further explained that a movable block 45 is provided on the outer flat plate 36, and the transmission column 39 passes through one end of the mounting platform 42 and is directly installed and fixed to the movable block 45. This installation method can be rotatable, so when the transmission column 39 rotates, it rotates synchronously relative to the movable block 45.

[0060] It should be further noted that the aforementioned outer flat sheet 36 is also a flat sheet.

[0061] When the mesh fabric 22 is in the stored state, the coil spring 35 is in the first state; as the mesh fabric 22 is gradually unfolded, the coil spring 35 gradually switches from the first state to the second state; the change in the vertical position of the outer flat piece 36 changes the tension of the first state.

[0062] It is understandable that the first state mentioned above refers to the relaxed state of the coil spring 35 when the mesh fabric 22 is in the retracted state, at which time there is a certain gap between the layers of the coil spring 35; while when the mesh fabric 22 is gradually unfolded, the layers of the coil spring 35 are pulled to gradually tighten and adhere, so as to switch from the first state to the second state. When the mesh fabric 22 is fully unfolded, the coil spring 35 is in a fully tightened state.

[0063] It should be further explained that the advantage of setting up the preload assembly is that the preload of the coil spring 35 can be adjusted. In the initial state, the preload of the coil spring 35 is at its most relaxed state, so the position of the moving block 45 is at the end closest to the mounting platform 42 (e.g., ...). Figure 5 As shown), after prolonged use, the coil spring 35 will gradually reduce its elasticity. At this point, the user only needs to rotate the transmission column 39, which, through the threaded connection between the transmission column 39 and the transmission block 38, will push the moving block 45 to the side away from the mounting platform 42. Because the outer end of the coil spring 35 is pushed, the layers of the coil spring 35 are tightened, thereby increasing the preload of the coil spring 35, maintaining the tension of the mesh fabric 22, and extending the service life of the mesh fabric 22 (e.g., ...). Figure 7 (As shown).

[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.
