DETAILED DESCRIPTION

[0046] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0047] In the description of the present invention, it should be understood that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally located component. When a component is considered to be "disposed on" another component, it may be directly disposed on the other component or there may be a centrally located component.

[0048] In addition, the terms "long", "short", "inside", "outside", etc. that indicate orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention. They do not indicate or imply that the device or component referred to must have this specific orientation or operate in a specific orientation structure, and should not be understood as a limitation of the present invention.

[0049] The following is combined with Figure 1-6 The technical solution of the utility model is further illustrated through specific implementation methods.

[0050] Example 1:

[0051] Please refer to Figure 1 and Figure 2 The embodiment of the utility model provides an automatic opening and closing clothes hanger, which is used in a tunnel clothes dryer. It mainly unloads the clothes hung thereon automatically by automatically opening and closing, so as to reduce labor costs and improve the degree of automation of the tunnel clothes dryer.

[0052] To achieve the above functions, the hanger structure includes a base 1, a first swing arm 2, a second swing arm 3, a locking assembly 4 and a driving assembly 5 (not shown in the figure), wherein the base 1 is used to provide an installation position for the first swing arm 2, the second swing arm 3 and the locking assembly 4. In this embodiment, the first swing arm 2 and the second swing arm 3 are both rod-shaped structures, and the first swing arm 2 and the second swing arm 3 are respectively rotatably installed on the base 1. Usually, a rotating shaft can be fixedly installed on the first swing arm 2 and the second swing arm 3, and a bearing can be installed on the base 1. By assembling the rotating shaft into the bearing, the rotatable installation of the first swing arm 2 and the second swing arm 3 can be achieved.

[0053] It needs to be explained that when installing the first swing arm 2 and the second swing arm 3, they need to be set symmetrically with each other. It can be understood that a symmetry plane passing through the geometric center is selected on the base 1, and the first swing arm 2 and the second swing arm 3 are set mirror-symmetrically along the symmetry plane. In this way, the first swing arm 2 and the second swing arm 3 can be mirror-symmetrical when rotating, thereby ensuring that a balanced supporting force can be provided when supporting clothes.

[0054] Furthermore, the locking assembly 4 is slidably set on the base body 1 and is connected to the first swing arm 2 and the second swing arm 3 respectively. The locking assembly 4 pulls the first swing arm 2 and the second swing arm 3 to swing simultaneously in a sliding manner, thereby playing a force-related role; in addition, the locking assembly 4 is also used to keep the first swing arm 2 and the second swing arm 3 open to each other or closed to each other, which is equivalent to locking the first swing arm 2 and the second swing arm 3. It should be explained here that the role of locking the first swing arm 2 and the second swing arm 3 is: when the first swing arm 2 and the second swing arm 3 remain in an open state to each other, only the first swing arm 2 and the second swing arm 3 in the locked state can be used for clothes to be placed, so as to ensure the stability of clothes when hanging.

[0055] In addition, the driving component 5 is used to drive the locking component 4 to slide back and forth so that the first swing arm 2 and the second swing arm 3 switch between the open and closed states. When the first swing arm 2 and the second swing arm 3 are converted from the open state to the mutually closed state, the clothes hanging on the first swing arm 2 and the second swing arm 3 may automatically slide off, thereby replacing the manual unloading method of removing the clothes, thereby achieving the purpose of reducing labor intensity.

[0056] Reference Figure 2 and Figure 3 In order to drive the first swing arm 2 and the second swing arm 3 to swing, specifically, a slide groove 6 is provided in the internal recess of the base body 1, and the slide groove 6 is located between the first swing arm 2 and the second swing arm 3. The locking assembly 4 includes a connecting member 41, and the connecting member 41 is slidably installed in the slide groove 6. At this time, the connecting member 41 can slide between the first swing arm 2 and the second swing arm 3.

[0057] At the same time, the connecting member 41 is connected to the first swing arm 2 and the second swing arm 3. Specifically, an extension portion is provided at one end of the first swing arm 2 to extend into the chute 6, and a first strip groove 21 is formed on the extension portion of the first swing arm 2 along the length direction, extending through both sides. Correspondingly, an extension portion is also provided at one end of the second swing arm 3 to extend into the chute 6, and a second strip groove 31 is formed on the extension portion of the second swing arm 3 along the length direction, extending through both sides.

[0058] Furthermore, a first connecting portion 411 is fixedly provided on the side of the connecting member 41 close to the first swing arm 2, and the first connecting portion 411 penetrates into the first strip groove 21 and slides in the first strip groove 21; correspondingly, a second connecting portion 412 is fixedly provided on the side of the connecting member 41 close to the second swing arm 3, and the second connecting portion 412 penetrates into the second strip groove 31 and slides in the second strip groove 31.

[0059] Based on the above structural arrangement, during the sliding process of the connecting block, the first swing arm 2 can be driven to swing due to the mutual sliding cooperation between the first connecting portion 411 and the first strip groove 21. Similarly, the second swing arm 3 can be driven to swing due to the mutual cooperation between the second connecting portion 412 and the second strip groove 31. In summary, by driving the connecting member 41 to slide, the opening and closing actions between the first swing arm 2 and the second swing arm 3 can be achieved.

[0060] Optionally, in order to make the first swing arm 2 and the second swing arm 3 swing more smoothly, in this embodiment, the first connecting part 411 and the second connecting part 412 are both cylindrical structures, which can reduce structural friction and make the structure smoother.

[0061] Reference Figure 3 In order to enable the first swing arm 2 and the second swing arm 3 to maintain the open and closed states, the locking assembly 4 also includes an elastic locking member 42, wherein a locking groove 413 is recessed on at least one side of the connecting member 41, and the elastic locking member 42 is movably engaged with the locking groove 413 in an elastic manner, thereby achieving the purpose of locking.

[0062] Specifically, in this embodiment, the elastic locking component 42 includes a mounting sleeve 421, a locking bead 422 and a spring 423. The mounting sleeve 421 is a circular sleeve structure with one end open and the other end closed. The mounting sleeve 421 is fixed to the base body 1. During installation, a mounting hole can be set through one side of the base body 1, and the mounting sleeve 421 can be assembled in the mounting hole by threaded connection or interference fit to complete its installation.

[0063] On this basis, the spring 423 is placed in the mounting sleeve 421, and the locking bead 422 is placed at the opening of the mounting sleeve 421. The opening size of the mounting sleeve 421 can be larger than the size of the locking bead 422, so that the locking bead 422 can be movably set in the mounting sleeve 421, and then the locking bead 422 can be snap-fitted with the locking groove 413.

[0064] At this time, the two ends of the spring 423 are connected to the mounting sleeve 421 and the locking bead 422 respectively. The spring 423 can apply a thrust to the locking bead 422 to engage in the locking groove 413. On the one hand, when the locking bead 422 is engaged in the locking groove 413, it can apply resistance to the connecting member 41, making the connecting member 41 less likely to slide, thereby achieving a locking effect; on the other hand, if a sufficiently large thrust is applied to the connecting member 41, the locking bead 422 can be pushed to retract and loosen the locking groove 413, thereby providing freedom of movement for the opening and closing actions of the first swing arm 2 and the second swing arm 3, thereby achieving structural unlocking.

[0065] Furthermore, in order to optimize the structural stability during the locking process, the elastic locking parts 42 can be set into multiple groups, and the multiple groups of elastic locking parts 42 are arranged at intervals along the moving path of the connecting part 41. In this way, double-layer locking can be achieved, so that the first swing arm 2 and the second swing arm 3 can withstand greater pressure, the structure is not easy to loosen, and the stability is optimized and improved.

[0066] It can be understood that the specific number of elastic locking parts 42 can be two groups, four groups or six groups. The specific number can be adjusted according to actual needs and is not specifically limited here. In this embodiment, the number of elastic locking parts 42 is set to four groups, and the four groups of elastic locking parts 42 are divided into two groups. The two groups of elastic locking parts 42 are respectively arranged on the opposite sides of the connecting part 41. Correspondingly, the locking grooves 413 are also correspondingly arranged twice on the opposite sides of the connecting part 41. Through the above arrangement, the connecting part 41 can be subjected to more balanced force and the structure is not easily overloaded.

[0067] Further, refer to Figure 2 In actual application, the base body 1, the first swing arm 2, the second swing arm 3 and the locking assembly 4 are usually arranged on the feeding device 1002 of the tunnel dryer. The feeding device 1002 is responsible for driving the above components to move and transfer to achieve the purpose of transferring clothes. In order to improve the stability of the clothes hanger during transfer, a walking wheel 8 is rotatably installed on the base body 1. The walking wheel 8 can roll with the tunnel body 1001, thereby making the clothes smoother during transfer and the structure more reasonable.

[0068] It should be explained that the specific setting position of the walking wheel 8 can be adaptively adjusted according to the specific shape of the equipment. For example, the walking wheel 8 can be set on the back of the base 1, or the walking wheel 8 can be set on the top of the base 1. There is no restriction on the setting position of the walking wheel 8 here.

[0069] Reference Figure 5 and Figure 6 In the process of the first swing arm 2 and the second swing arm 3 opening and closing each other, they also need to be used in conjunction with the driving assembly 5. The driving assembly 5 is generally fixedly installed on the tunnel body 1001. At this time, under the drive of the feeding device 1002, the base body 1, the first swing arm 2, the second swing arm 3 and the locking assembly 4 and other components will move compared to the driving assembly 5. When the base body 1, the first swing arm 2, the second swing arm 3 and the locking assembly 4 and other components pass through the driving assembly 5, the driving assembly 5 drives the locking assembly 4 to slide to realize the state switching of the first swing arm 2 and the second swing arm 3.

[0070] Specifically, the driving assembly 5 includes a first driving part 51 and a second driving part 52. The first driving part 51 is used to drive the locking assembly 4 to slide toward the first direction; the second driving part 52 is used to drive the locking assembly 4 to slide toward the second direction, and the first direction and the second direction are opposite to each other; in this embodiment, the base body 1, the first swing arm 2, the second swing arm 3 and the locking assembly 4 are vertically arranged, so the first direction and the second direction both extend vertically.

[0071] Among them, reference Figure 4 In this embodiment, the first driving part 51 is provided in a block-shaped structure, and is tilted at its top surface to form an inclined guide surface 511. The extending direction of the inclined guide surface 511 is consistent with the moving path of the clothes in the feeding device 1002. Accordingly, the locking component 4 is provided with a guide wheel 7 (which can be combined with the inclined guide surface 511) that slides with the inclined guide surface 511. Figure 3 ), in this embodiment, an avoidance opening is opened on the base body 1, and an extension arm is integrally provided on the connecting member 41, the extension arm passes through the avoidance opening, and the guide wheel 7 is rotatably installed on the guide wheel 7. At this time, under the extension action of the extension arm, the guide wheel 7 can be opposite to the inclined guide surface 511, and then the guide wheel 7 can pass through the inclined guide surface 511 under the drive of the feeding device 1002. When the guide wheel 7 passes through the inclined guide surface 511, it can drive the locking assembly 4 to slide toward the first direction.

[0072] In addition, refer to Figure 5 The second driving part 52 includes a driving cylinder 521 and a push block 522. The driving cylinder 521 can be a cylinder component with a telescopic function, such as a cylinder, a hydraulic cylinder, or an electric cylinder, and is not specifically limited here. In this embodiment, a cylinder structure is used as an example. The cylinder is fixedly installed on the tunnel body 1001. The output rod of the driving cylinder 521 is parallel to the second direction and is arranged vertically downward. The push block 522 is fixedly installed on the telescopic rod.

[0073] Based on the above structural setting, when the extension arm or guide wheel 7 passes through the area opposite to the push block 522, the drive cylinder 521 is started, the telescopic rod pushes the push block 522 out, and the push block 522 abuts against the extension arm or guide wheel 7, and finally the drive cylinder 521 can push the locking assembly 4 toward the second direction through the push block 522, thereby adjusting the locking assembly 4.

[0074] It should be noted that, in one embodiment, the directions of the first drive part 51 and the second drive part 52 can be reversed, as long as the pushing directions of the two on the locking component 4 are opposite, so that the adjustment effect can also be achieved; furthermore, in another embodiment, the second drive part 52 can be discarded, and two sets of first drive parts 51 with opposite directions can be used at the same time. Correspondingly, the first drive part 51 can be discarded, and two sets of second drive parts with opposite directions can be used at the same time. No matter what combination is adopted, as long as it is guided by the inclined surface and pushed by the drive cylinder 521, it should be included in the same scope of interpretation and will not be elaborated here.

[0075] The implementation principle of this embodiment is: under the drive of the driving component 5, the locking component 4 can be adjusted, thereby controlling the first swing arm 2 and the second swing arm 3 to remain in an open or closed state. During the process of the first swing arm 2 and the second swing arm 3 being transformed from open to closed, the clothes hanging on the two can automatically slide down and be discharged, solving the problem of low efficiency, time-consuming and labor-intensive manual removal of clothes after drying.

[0076] Example 2:

[0077] Reference Figure 6 This embodiment discloses a tunnel clothes dryer, including the automatic opening and closing clothes hanger provided in the first embodiment. The tunnel clothes dryer also includes a tunnel body 1001, a drying system and a feeding device 1002, wherein the tunnel body 1001 mainly includes a frame and partitions installed on the frame, and a plurality of partitions are separated to form a plurality of different processing channels for sequentially performing the steps of pulling on clothes, atomizing, drying, cooling and taking out clothes.

[0078] The drying system mainly includes a device that can generate hot air, such as a hot air blower, which will not be described in detail here. The drying system is installed on the tunnel body 1001 and emits hot air in one of the processing channels to achieve a drying effect.

[0079] Furthermore, the feeding device 1002 is installed on the top of the tunnel body 1001. The feeding device 1002 adopts a transmission device composed of a chain, a sprocket and a motor, and its structure is not described here. The chain passes through multiple processing channels in sequence, and the base 1 of the hanger is installed on the chain. By driving the chain to rotate, the clothes are driven through different processing channels. The whole process is fast and efficient.

[0080] In addition, the driving component 5 is installed on the tunnel body 1001. When setting the driving component 5, the first driving part 51 and the second driving part 52 can be respectively arranged in the clothing area and the unloading area. Through the circulation of the chain, the circulation of clothes can be realized. In this way, a tunnel dryer that can dry clothes efficiently is obtained, which reduces the energy consumed in the unloading process and optimizes the degree of automation of the equipment.

[0081] Optionally, in order to further improve the degree of automation of the tunnel dryer, a PLC control system can be added, and humidity sensors, temperature sensors and other sensors can be installed on the tunnel body 1001. The PLC control system is electrically connected to the humidity sensor, temperature sensor, feeding device 1002, drying system and drive component 5 respectively. The humidity sensor is used to detect humidity, and the temperature sensor is used to detect temperature. The feeding device 1002, drying system and drive component 5 are controlled to operate automatically through program settings.

[0082] So far, 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.
