Description

Technical Field

[0001] This utility model relates to the field of drying technology, and in particular to a clothes drying machine main unit and a clothes drying machine. Background Technology

[0002] Clothes drying racks are a convenient device in modern home life. They can be raised and lowered through specific mechanical devices, making it convenient for users to dry clothes at different heights. With the advancement of technology and the diversification of consumer needs, the types of clothes drying racks on the market are becoming more and more diverse.

[0003] In a clothes drying rack, a steel wire rope passes through a pulley and connects to the clothes drying rod to control the raising and lowering of the clothes drying rod. The pulley is fixedly installed on the main unit. Different models have different installation positions of the drive components, so the angle at which the steel wire rope leading from the drive components connects to the pulley is different. The pulley angle needs to be adapted and adjusted, so that each model needs to develop a new mold based on the internal layout structure of the clothes drying rack main unit, which greatly increases the development cost of the clothes drying rack.

[0004] Therefore, it is necessary to provide a clothes drying rack main unit and a clothes drying rack to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this utility model is to provide a clothes drying machine main unit and a clothes drying machine that can solve the above-mentioned problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Firstly, a clothes drying rack main unit is provided, comprising:

[0008] A pulley assembly, mounted on the mounting plate of the main unit, for the passage of a traction rope and for turning the traction rope;

[0009] The mounting plate has mounting parts at both ends, and the pulley assembly is mounted on the mounting parts with adjustable angle to turn the traction rope passing through the pulley assembly from various directions.

[0010] As an optional implementation, the mounting part is an arc-shaped mounting groove, and the bottom of the pulley assembly is mounted on the arc-shaped mounting groove. The pulley assembly can slide in the arc-shaped mounting groove to select the corresponding installation position for installation and fixation, so as to realize that the pulley assembly is installed at a corresponding angle relative to the host.

[0011] As an optional implementation, the pulley assembly includes a pulley frame, a pulley shaft, and a pulley. The pulley frame has two first through holes arranged opposite each other. The pulley shaft passes through the two first through holes and is disposed on the pulley frame. The pulley is mounted on the pulley frame via the pulley shaft.

[0012] As an optional implementation, the pulley assembly further includes an anti-drop wire frame, which is disposed between the pulley and the pulley frame and covers the pulley to prevent the traction rope from detaching from the pulley.

[0013] As an optional implementation, the anti-drop wire frame is a U-shaped structure with two opposing side plates. Each side plate has a limiting protrusion and a second through hole. The pulley frame has a limiting groove corresponding to the limiting protrusion. When the anti-drop wire frame is installed on the pulley frame, the limiting protrusion engages in the limiting groove. The second through hole corresponds to the first through hole, and the pulley shaft passes through both the second through hole and the first through hole in sequence.

[0014] As an optional implementation, the two side plates of the anti-drop wire frame are provided with folded edges at the side openings facing the anti-drop wire frame, and the folded edges abut against the pulleys.

[0015] As an optional implementation, the pulley assembly is provided with an elastic element, one end of which is connected to the pulley shaft and the other end is connected to the top of the pulley frame. The first through hole on the pulley frame is an elongated through hole, and the pulley shaft can move in the vertical direction in the first through hole. When the clothes drying machine is in an unloaded state, the pulley shaft is located at the upper part of the first through hole.

[0016] As an optional implementation, the elastic element is specifically a spring, with hook structures at both ends of the spring, and grooves that cooperate with the hook structures on both the pulley shaft and the pulley frame.

[0017] As an optional implementation, the pulley shaft is further provided with a first limiting plane, which is located at one end of the pulley shaft and passes through the first through hole. The first through hole is provided with a second limiting plane corresponding to the first limiting plane.

[0018] Secondly, a clothes drying rack is provided, comprising:

[0019] Lifting mechanism;

[0020] As described in the first aspect, the first end of the lifting mechanism is mounted on the main unit, the second end is movably mounted on the bracket, and the bracket is also connected to the drive component in the main unit via a traction rope.

[0021] Based on the above technical solution, this disclosure has at least the following beneficial effects:

[0022] By setting an installation part on the main mounting plate of the clothes drying rack, the pulley assembly can be installed at different angles. This satisfies the different guiding angles of the traction rope extending from the drive component to the pulley assembly in different clothes drying rack main units, eliminating the need for separate molds for different models and greatly saving the development cost of the clothes drying rack.

[0030] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this utility model are further described in detail below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0033] During the development of clothes drying racks, the installation positions of the drive components vary slightly between different models. However, all models ultimately require the traction rope to be led to the pulleys at the middle of both ends of the main unit, and then connected to the drying rod assembly. Due to the different positions of the drive components, the angle at which the traction rope extends from the drive component to the pulleys varies, often necessitating a redesign of the pulley installation positions based on the drive component's location, thus increasing the development cost of the clothes drying rack. To solve this problem, this utility model provides an improved clothes drying rack main unit and clothes drying rack.

[0034] Please refer to the instruction manual attached. Figures 1-5 This embodiment provides a clothes drying rack main unit, including a pulley assembly 10. The pulley assembly 10 is mounted on a mounting plate 20 of the clothes drying rack main unit and is used for the traction rope to pass through and to turn the traction rope. The mounting plate 20 has mounting parts at both ends, and the pulley assembly 10 is mounted on the mounting parts with adjustable angle to turn the traction rope passing through the pulley assembly 10 from various directions.

[0035] By setting mounting parts at both ends of the clothes drying rack main unit mounting plate 20, the pulley assembly 10 can be installed on the mounting parts at different angles, which can meet the different guiding angles of the traction rope in different clothes drying rack main units from the drive component (not shown in the figure) to the pulley assembly 10. There is no need to make separate molds for different drive positions of different models, which greatly saves the development cost of clothes drying racks.

[0036] Since the pulley assembly 10 is generally located at the middle of both ends of the mounting plate 20 of the clothes drying machine main unit, with the center line of the width direction of the clothes drying machine main unit as the axis, by setting the above-mentioned mounting part, in addition to installing the pulley assembly 10 in the conventional middle position, the pulley assembly 10 can also be installed to the left or right relative to the center line based on the middle position. When the traction rope extends from the left or right side relative to the center to the position of the pulley assembly 10 at the middle of both ends of the mounting plate 20, it is only necessary to install the pulley assembly 10 to the left or right accordingly. Technicians do not need to redetermine the installation position of the pulley assembly 10 according to the angle of the traction rope and then re-open the mold.

[0037] In some embodiments, the mounting part is an arc-shaped mounting groove 21, and the bottom of the pulley assembly 10 is mounted on the arc-shaped mounting groove 21. The pulley assembly 10 can slide in the arc-shaped mounting groove 21 to select the corresponding mounting position for installation and fixation, so as to realize the installation of the pulley assembly 10 relative to the host at a corresponding angle.

[0038] By setting the mounting part as an arc-shaped mounting groove 21, the pulley assembly 10 is installed on the arc-shaped mounting groove 21, and the pulley assembly 10 can slide along the groove in the arc-shaped mounting groove 21 to select a suitable installation angle before fixing it in place. This increases the selectable range of installation angles for the pulley assembly 10, making it suitable for guiding the traction rope of the clothes drying rack main unit of different models. It eliminates the need for separate molds for each model, saving R&D costs.

[0039] The aforementioned mounting section can be implemented in various ways. In addition to adopting the form of an arc-shaped mounting groove 21, it can also be configured with mounting holes arranged in a dot matrix at both ends of the mounting plate 20 of the clothes drying machine main unit. The bottom of the pulley assembly 10 is limited within the range of the dot matrix mounting holes. The pulley assembly 10 can be installed in any two mounting holes according to actual needs. However, it should be noted that the installation position of the pulley assembly 10 is always kept at the middle position in the width direction of both ends of the clothes drying machine main unit, and it is only installed at different angles along this middle position.

[0040] In some embodiments, the pulley assembly 10 includes a pulley frame 11, a pulley shaft 13, and a pulley 12. The pulley frame 11 has two first through holes 111 disposed opposite to each other. The pulley shaft 13 passes through the two first through holes 111 and is disposed on the pulley frame 11. The pulley 12 is mounted on the pulley frame 11 via the pulley shaft 13.

[0041] In the pulley assembly 10, the pulley 12 is rotatably mounted on the pulley shaft 13. Two opposing first through holes 111 are provided on the pulley frame 11, and the two first through holes 111 are set at the same horizontal height. The pulley shaft 13 passes through the two first through holes 111 and is placed on the pulley frame 11. At this time, the pulley 12 is located in the middle of the pulley frame 11. The traction rope extends from the drive component, passes through the top of the pulley 12, turns and connects to the clothes drying rod assembly of the clothes drying machine.

[0042] The pulley frame 11 is provided with two support feet. The two support feet can be fixed to the mounting part of the mounting plate 20 by screw structure. When the mounting part is an arc-shaped mounting groove 21, both support feet are slidably installed in the arc-shaped mounting groove 21. That is, the mounting structure of the two support feet can slide in the arc-shaped mounting groove 21. After selecting a suitable installation position, it is fixedly installed to adapt to the different angle guidance requirements of the traction rope.

[0043] In some embodiments, the pulley assembly 10 further includes an anti-drop wire frame 14, which is disposed between the pulley 12 and the pulley frame 11 and covers the pulley 12 to prevent the traction rope from detaching from the pulley 12.

[0044] By setting an anti-drop wire frame 14 between the pulley 12 and the pulley frame 11, and with the anti-drop wire frame 14 covering the pulley 12, the traction rope can be confined between the pulley 12 and the anti-drop wire frame 14, limiting the movement space of the traction rope and preventing the traction rope from detaching from the pulley during the operation of the clothes drying machine, thus avoiding a safety accident.

[0045] In some embodiments, the anti-drop wire frame 14 is a "U" shaped structure with two side plates 141 arranged opposite to each other. The two side plates 141 are provided with limiting protrusions 143 and second through holes 142 respectively. The pulley frame 11 is provided with limiting grooves 112 corresponding to the limiting protrusions 143. When the anti-drop wire frame 14 is installed on the pulley frame 11, the limiting protrusions 143 are engaged in the limiting grooves 112. The second through hole 142 corresponds to the first through hole 111, and the pulley shaft 13 passes through the second through hole 142 and the first through hole 111 in sequence.

[0046] By setting the anti-drop cable frame 14 as a "U"-shaped structure, with its open side cover mounted on the pulley 12, the movement space of the traction rope is limited. The anti-drop cable frame 14 has two opposing side plates 141, each with a limiting protrusion 143. The pulley frame 11 has a limiting groove 112 corresponding to the limiting protrusion 143, allowing the limiting protrusion 143 to engage with the limiting groove 112, thus limiting the anti-drop cable frame 14. The two side plates 141 of the anti-drop cable frame 14 also have second through holes 142, through which the pulley shaft 13 passes sequentially, connecting the second through hole 142 to the first through hole 111, thereby limiting the second through hole 142 of the anti-drop cable frame 14 to the same horizontal level as the first through hole 111. By limiting the second through hole 142 and the limiting protrusion 143, the anti-drop wire frame 14 can be limited in all circumferential directions, so that the anti-drop wire frame 14 is more stably covered on the pulley 12, preventing the traction rope from falling off the pulley 12, and the pulley 12 can always guide the traction rope.

[0047] In some embodiments, two side plates 141 disposed opposite to each other on the anti-drop wire frame 14 have folded edges 144 formed at the side openings facing the anti-drop wire frame 14, and the folded edges 144 abut against the pulleys 12.

[0048] By setting folded edges 144 on the two side plates 141 of the anti-skid frame 14, the folded edges 144 abut against the pulley 12. The folded edges 144 create clearance space on the side plates 141, which helps the side plates 141 of the anti-skid frame 14 avoid the middle protrusion of the pulley 12 and surround the pulley 12 from the outside. The anti-skid frame 14 can be more stably covered on the pulley 12 and will not easily shake. As a result, the traction rope cannot leave the space between the anti-skid frame 14 and the pulley 12, ensuring the normal operation of the clothes drying rack.

[0049] In some embodiments, the pulley assembly 10 is provided with an elastic element 15. One end of the elastic element 15 is connected to the pulley shaft 13, and the other end is connected to the top of the pulley frame 11. The first through hole 111 on the pulley frame 11 is an elongated through hole. The pulley shaft 13 can move in the up and down direction in the first through hole 111. When the clothes drying machine is in an unloaded state, the pulley shaft 13 is located at the upper part of the first through hole 111.

[0050] By using an elastic element 15 to connect the pulley frame 11 and the pulley shaft 13, and the pulley shaft 13 can be displaced vertically in the first through hole 111, when the pulley assembly 10 is in an unloaded state, the pulley shaft 13 is held in the upper part of the first through hole 111 by the elastic force of the elastic element 15. When the load is increased on the clothes drying rack, the pulley shaft 13 will slowly move to the lower part of the first through hole 111 under the influence of the elastic force of the elastic element 15 as the load gradually increases, without drastic displacement in the first through hole 111, which helps to extend the service life of the clothes drying rack parts.

[0051] In some embodiments, the elastic element 15 is specifically a spring, both ends of which are provided with hook structures, and both the pulley shaft 13 and the pulley frame 11 are provided with grooves that cooperate with the hook structures.

[0052] A first groove 131 is provided on the pulley shaft 13, and a second groove (not shown in the figure) is provided on the pulley frame. The hook structures at both ends of the spring are connected to the first groove 131 and the second groove respectively, so that the spring can be buffered by the pulley shaft 13 when the clothes drying machine is working, thereby improving the service life of the parts.

[0053] In some embodiments, the pulley shaft 13 is further provided with a first limiting plane 132, which is located at one end of the pulley shaft 13 and passes through a first through hole 111. The first through hole 111 is provided with a second limiting plane 1111 corresponding to the first limiting plane 132.

[0054] By setting a first limiting plane 132 and a second limiting plane 1111 on the pulley shaft 13 and the first through hole 111, when the pulley shaft 13 passes through the first through hole 111, the first limiting plane 132 and the second limiting plane 1111 abut against each other to restrict the rotation of the pulley shaft 13 in the first through hole 111. The pulley shaft 13 will not rotate with the rotation of the pulley 12, so that the elastic element 15 can be stably connected to the pulley shaft 13 and will not disengage due to the rotation of the pulley shaft 13, further improving the running stability of the pulley assembly 10. Since the first limiting plane 132 is only set at one end of the pulley shaft 13, and its middle part and the other end are still conventional round shafts, it does not affect the rotation of the pulley 12 on the pulley shaft 13.

[0055] In some embodiments, a clothes drying rack is provided, including the aforementioned clothes drying rack main unit, and further including a lifting mechanism. The first end of the lifting mechanism is mounted on the clothes drying rack main unit, and the second end is movably mounted on the bracket of the drying rod assembly. The bracket is also connected to the drive component in the main unit via a traction rope (i.e., a steel wire rope).

[0056] The drive unit is located in the main unit of the clothes drying rack and is used to provide power to the clothes drying rack. The traction rope extends from the drive unit, passes through the pulley assembly 10 and then turns, and then connects to the bracket. Through the drive unit, the pulling rope can be retracted and released, thereby controlling the raising and lowering of the drying rod assembly, realizing electric lifting control, and switching between the state of drying clothes and taking clothes in, improving the user experience.
