Description

Technical Field

[0001] This utility model belongs to the field of household appliance technology, specifically relating to a door hinge, a door assembly, and a garment processing device with the door assembly installed. Background Technology

[0002] The existing roller-type garment handling equipment has its garment loading and unloading port located on the front side of the equipment's housing. The door of the roller-type garment handling equipment is connected to the front panel of the equipment via a door hinge. The door can rotate relative to the housing to open and close the garment loading and unloading port.

[0003] However, due to the large weight of the door, especially since some models have additional functional modules on the door, which further increases the weight, the door is prone to sagging during use, causing it to fail to close properly and affecting the sealing effect on the clothing loading opening, seriously impacting the user experience.

[0004] Existing technologies typically address door sagging issues passively, meaning that maintenance is performed on the door when sagging occurs to ensure its continued usability. For example, Chinese invention patent application CN201910968872.X discloses an installation structure for an observation window door hinge and a clothing handling device. By setting multiple fixing parts on the front panel, each fixing part having multiple holes distributed along an arc, when multiple fasteners are fixed to different holes, the hinge base with the fasteners rotates relative to the front panel. This allows adjustment of the relative position between the door lock hook of the observation window door connected to the hinge base and the door lock hole on the front panel, enabling the adjusted observation window door to lock properly. Chinese utility model patent application number CN202121228784.5 discloses an observation door and a drum washing machine. The observation door is equipped with a correction structure, which includes a top shaft and a lifting component. The top shaft is connected to a hinge shaft connecting the inner frame and the outer frame, and the top shaft abuts against the hinge frame. The lifting component is used to drive the top shaft to move upward. The top shaft can drive the hinge frame and the door body connected to the hinge frame to move upward. The upward movement of the door body can be used to compensate for the sagging of the door body so that the door body can be closed.

[0005] However, none of the above solutions can reduce the occurrence of door sagging.

[0006] Therefore, designing a door hinge that can reduce door sagging has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0007] This utility model provides a door hinge that, by setting an elastic element between the hinge sleeve and the hinge base, can use the elastic force of the elastic element to clamp the hinge sleeve axially, thus solving the problem of door sagging that easily occurs during the use of existing clothing handling equipment.

[0008] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0009] A door hinge, comprising:

[0010] Hinge seat, with a hinge pin on it;

[0011] Hinge sleeve, fitted onto the hinge axis;

[0012] An elastic element is provided between the hinge sleeve and the hinge base, which is used to clamp the hinge sleeve axially.

[0013] In the above scheme, the elastic element is a compression spring.

[0014] Furthermore, the elastic element is positioned between one end of the hinge sleeve and the hinge base, so that the other end of the hinge sleeve abuts against the hinge base.

[0015] Furthermore, the elastic element and the hinge sleeve are coaxially arranged, with the first end of the elastic element abutting against the hinge seat and the second end of the elastic element abutting against the end face of the hinge sleeve.

[0016] Furthermore, a gasket is provided between the first end of the elastic element and the hinge seat, and / or a gasket is provided between the second end of the elastic element and the end face of the hinge sleeve.

[0017] Furthermore, the elastic element is disposed between the lower end face of the hinge sleeve and the hinge seat, so that the upper end face of the hinge sleeve abuts against the hinge seat.

[0018] The upper and lower end faces of the hinge sleeve, as well as the faces on the hinge seat that are opposite to the upper and lower end faces of the hinge sleeve, are all designed as planes extending radially along the hinge sleeve.

[0019] Furthermore, the hinge seat includes a mounting part and two hinge arms connected to the mounting part, the two hinge arms being arranged opposite to each other, and the hinge shaft being arranged between the two hinge arms.

[0020] The elastic element is positioned between one end of the hinge sleeve and a hinge cantilever, so that the other end of the hinge sleeve abuts against another hinge cantilever.

[0021] Furthermore, the hinge shaft and the hinge cantilever are fixedly connected, or the hinge shaft and the hinge cantilever are axially limited.

[0022] This utility model also provides a door assembly, including a door body, which is mounted on a support structure via the aforementioned door hinges.

[0023] Furthermore, the door is mounted on the supporting structure via a set of hinges; or,

[0024] The door is mounted on the support structure by multiple sets of door hinges arranged at intervals along the vertical direction, with the hinge axes of the multiple sets of door hinges being coaxial.

[0025] The hinge sleeve is equipped with a mounting plate for connecting to the door body.

[0026] This utility model also provides a garment processing device, including a box body, on which the above-mentioned door assembly is installed.

[0027] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art.

[0028] 1. This utility model, by setting an elastic element between one end of the hinge sleeve and the hinge seat, can utilize the elastic force of the elastic element to make the other end of the hinge sleeve abut against the hinge seat, clamping the hinge sleeve axially. The axial clamping force of the elastic element on the hinge sleeve can reduce the radial force between the hinge sleeve and the hinge shaft. Under the axial clamping force and the limiting effect of the hinge shaft, the hinge sleeve remains in a vertical state, which can keep the door body stably in a horizontal state, thereby reducing the occurrence of door sagging and improving the user experience.

[0029] 2. This utility model places the elastic element between the lower end of the hinge sleeve and the hinge seat, which can make the elastic element an intermediate structure between the lower end of the hinge sleeve and the hinge seat, thereby reducing the wear between the lower end of the hinge sleeve and the hinge seat.

[0030] 3. By setting a fixed connection between the hinge shaft and the hinge cantilever, this utility model can avoid the assembly gap between the hinge shaft and the hinge cantilever, thereby further reducing the occurrence of door sagging.

[0043] In existing technologies, the solutions to the problem of door sagging typically involve maintaining the door after sagging has occurred to allow it to continue being used, but this does not reduce the occurrence of sagging. To address this problem, this utility model provides a door hinge, such as... Figures 1 to 3 As shown.

[0044] The door hinge 3 includes a hinge base 31, a hinge shaft 33, and a hinge sleeve 32. The hinge shaft 33 is disposed on the hinge base 31, and the hinge sleeve 32 is sleeved on the hinge shaft 33. The hinge sleeve 32 can rotate relative to the hinge base 31, forming the door hinge 3. The door hinge 3 is also provided with an elastic element 34, which is disposed between the hinge base 31 and the hinge sleeve 32. Specifically, it is disposed between one end of the hinge sleeve 32 and the hinge base 31, so that the other end of the hinge sleeve 32 abuts against the hinge base 31.

[0045] In this embodiment, the door hinge 3 is used to install the door body 2. In some specific embodiments, the hinge seat 31 of the door hinge 3 is used to connect with the support structure, and the hinge sleeve 32 of the door hinge 3 is used to connect with the door body 2. Of course, it is also possible to set the hinge seat 31 to connect with the door body 2 and the hinge sleeve 32 to connect with the support structure, so that the door body 2 can be rotatably installed on the support structure.

[0046] In this embodiment, by providing an elastic element 34 between one end of the hinge sleeve 32 and the hinge seat 31, the elastic force of the elastic element 34 can be used to make the other end of the hinge sleeve 32 abut against the hinge seat 31, clamping the hinge sleeve 32 axially. The axial clamping force of the elastic element on the hinge sleeve can reduce the radial force between the hinge sleeve and the hinge shaft. Under the axial clamping force and the limiting effect of the hinge shaft, the hinge sleeve remains in a vertical state, which can keep the door body stably in a horizontal state, reduce the occurrence of door body 2 sagging, and improve the user experience.

[0047] In some specific embodiments, the hinge base 31 includes a mounting portion 311 and two hinge arms connected to the mounting portion 311. The two hinge arms are arranged opposite to each other, and a hinge shaft 33 is disposed between the two hinge arms. Specifically, the mounting portion 311 is mounted on a support structure, and the two hinge arms protrude from the same side of the mounting portion 311, spaced apart in the vertical direction. The end of each hinge arm connected to the mounting portion 311 is the fixed end of the hinge arm, and the end of the hinge arm away from the mounting portion 311 is the free end of the hinge arm. The hinge shaft 33 is connected to the free end of the hinge arm, and both ends of the hinge shaft 33 are respectively connected to the free ends of the two hinge arms.

[0048] The hinge sleeve 32 is disposed between two hinge arms and is used to connect to the door body 2. The hinge sleeve 32 is sleeved on the hinge shaft 33 between the two hinge arms, and the elastic element 34 is disposed between one end of the hinge sleeve 32 and one hinge arm, so that the other end of the hinge sleeve 32 abuts against the other hinge arm.

[0049] In this embodiment, two hinged cantilever arms are arranged vertically at intervals on the mounting part 311, and the hinge shaft 33 is connected to the free ends of the two hinged cantilever arms and extends vertically.

[0050] In this embodiment, for ease of discussion, the hinge cantilever that directly abuts against the end of the hinge sleeve 32 is defined as the first hinge cantilever 312, and the hinge cantilever that abuts against the end of the hinge sleeve 32 through the elastic member 34 is defined as the second hinge cantilever 313.

[0051] In some possible embodiments, the first hinge cantilever 312 is disposed above the second hinge cantilever 313, the elastic element 34 is disposed between the lower end of the hinge sleeve 32 and the second hinge cantilever 313, and the upper end of the hinge sleeve 32 abuts against the first hinge cantilever 312. In this embodiment, the elastic element 34 can adapt to the weight of the door 2 and provide sufficient support force. That is, the elastic force provided by the elastic element 34 is greater than the weight of the door 2.

[0052] Since the contact force between the lower end of the hinge sleeve 32 and the hinge cantilever located below is relatively large, the above arrangement allows the elastic element 34 to serve as an intermediate structure between the lower end of the hinge sleeve 32 and the hinge seat 31, thereby reducing the wear between the lower end of the hinge sleeve 32 and the hinge seat 31.

[0053] In some other possible embodiments, the second hinge cantilever 313 is disposed above the first hinge cantilever 312, the elastic element 34 is disposed between the upper end of the hinge sleeve 32 and the second hinge cantilever 313, and the lower end of the hinge sleeve 32 abuts against the first hinge cantilever 312. This arrangement helps to reduce the cost of the elastic element 34.

[0054] Preferably, in this embodiment, the first hinge cantilever 312 is disposed above the second hinge cantilever 313, and the elastic element 34 is a compression spring sleeved on the hinge shaft 33. The compression spring is disposed between the lower end of the hinge sleeve 32 and the second hinge cantilever 313, the upper end of the compression spring abuts against the lower end face of the hinge sleeve 32, and the lower end of the compression spring abuts against the top of the second hinge cantilever 313.

[0055] Preferably, the first end of the elastic element 34 abuts against the hinge seat 31, and the second end of the elastic element 34 abuts against the end face of the hinge sleeve 32. Preferably, a gasket 35 is provided between the first end of the elastic element 34 and the hinge seat 31, and / or, a gasket 35 is provided between the second end of the elastic element 34 and the end face of the hinge sleeve 32. By providing a gasket 35 at the end of the elastic element 34, the pressure on the end faces of the hinge seat 31 and / or the hinge sleeve 32 can be reduced, which is beneficial to improving the service life of the door hinge 3. At the same time, it can ensure stable abutment between the elastic element 34 and the end face of the hinge seat 31 and / or the hinge sleeve 32, thus ensuring the working stability of the door hinge 3.

[0056] In this embodiment, the gasket 35 is sleeved on the hinge shaft 33 and can slide along the hinge shaft 33.

[0057] In some preferred embodiments, washers 35 are provided at both ends of the compression spring, and the washers 35 are fixed to the ends of the elastic member 34.

[0058] More preferably, the side of the pad 35 away from the compression spring is set as a smooth plane, thereby reducing the torsional force on the compression spring during the rotation of the door body 2 and improving the service life of the door hinge 3.

[0059] Optionally, the connection between the two ends of the hinge shaft 33 and the hinge cantilever can be a fixed connection, or the hinge shaft 33 and the hinge cantilever can be axially limited.

[0060] Specifically, the free ends of the first hinge cantilever 312 and the second hinge cantilever 313 are respectively provided with pin holes, the pin holes on the first hinge cantilever 312 and the second hinge cantilever 313 are coaxially arranged, and the two ends of the hinge shaft 33 are respectively inserted into the pin holes.

[0061] In some possible embodiments, the end of the hinge shaft 33 is interference-fitted with the pin hole.

[0062] In some other possible embodiments, the hinge shaft 33 is rotatably engaged with the pin hole, and the hinge shaft 33 is provided with a radial protrusion that abuts against the upper end face of the second hinge cantilever 313. The hinge sleeve 32 is circumferentially limited to the hinge shaft 33, and the elastic element 34 is disposed between the radial protrusion and the lower end of the hinge sleeve 32. Therefore, during the rotation of the door body 2, the elastic element 34 will not be subjected to torsional force, further improving the service life of the door hinge 3.

[0063] Preferably, in this embodiment, the upper and lower end faces of the hinge sleeve 32 and the surfaces on the hinge seat 31 opposite to the upper and lower end faces of the hinge sleeve 32 are all set as planes extending radially along the hinge sleeve 32, so as to ensure the limiting effect of the hinge sleeve 32 and improve the stability and smoothness of the door body 2 during rotation.

[0064] Specifically, such as Figure 3 As shown, in this embodiment, the mounting part 311 is plate-shaped, the hinge cantilever is disposed on one side of the mounting part 311, and the other side of the mounting part 311 is used to fit against the support structure during installation.

The first segment 31-1 extends in a direction perpendicular to the mounting portion 311. One end of the first segment 31-1 is connected to the mounting portion 311 and serves as the fixed end of the hinge cantilever. The second segment 31-2 extends in a horizontal direction parallel to the mounting portion 311. One end of the second segment 31-2 is connected to the end of the first segment 31-1 away from the mounting portion 311 via the connecting segment 31-3. The end of the second segment away from the connecting segment 31-3 constitutes the free end of the hinge cantilever.

[0066] Preferably, the connecting segment 31-3 has an arc-shaped structure, connecting the first segment 31-1 and the second segment 31-2. The arc-shaped design creates a smooth transition area, avoiding stress concentration problems caused by sharp corners.

[0067] In this embodiment, both the top and bottom surfaces of the hinge cantilever are set as planes.

[0068] Preferably, in this embodiment, along the direction away from the connecting segment 31-3, the cross-sectional area of ​​the end of the first segment 31-1 connected to the mounting part 311 gradually increases to ensure the stability of the connection between the hinge cantilever and the mounting part 311.

[0069] Preferably, in this embodiment, the hinge sleeve 32 is provided with a mounting plate 36, which is used to connect to the door body 2. The mounting plate 36 is fixedly connected to the hinge sleeve 32.

A first groove profile is provided in the middle of the clearance opening, corresponding to the annular groove of the hinge sleeve 32. The assembly part is mounted on the mounting plate 36. The assembly part is provided with a second groove profile corresponding to the annular groove. The first groove profile and the second groove profile are arranged opposite to each other and spliced ​​to form an assembly groove for fixing the hinge sleeve 32, clamping the hinge sleeve 32 between the mounting plate 36 and the assembly part.
