Description

Technical Field

[0001] This utility model relates to the technical field of household appliance accessories, specifically to a mobile bracket for preventing accidental touch and a household appliance. Background Technology

[0002] The movable support is installed on the bottom of large, heavy equipment such as washing machines. When it is necessary to move the appliance, turn the handle so that it extends out from under the appliance, while the rollers contact the ground and push the appliance, raising it into a suspended state. Because the rollers are in contact with the ground at this time, the appliance can be moved with relatively little effort.

[0003] Such products have been disclosed in Chinese utility model patents with publication numbers CN223059787U, CN222543511U, CN222703012U, CN223036032U, CN222577842U, CN222122789U, CN222392371U, CN217995582U, CN218001033U, and CN218001068U.

[0004] The aforementioned movable bracket has the following problems when in use: when moving the appliance, if the handle is bumped by other objects, the handle is prone to turning. When the handle turns, the inner moving part will move relative to the outer fixed part, the roller will rise, and the bottom corner of the appliance will re-contact the bottom surface, hindering the movement of the appliance. Utility Model Content

[0005] To address the problem that the handle of existing mobile stands is prone to rotation due to collisions during use, the purpose of this utility model is to provide a mobile stand and household appliance that prevents accidental contact.

[0006] The technical solution provided by this utility model is as follows: Firstly, a mobile stand designed to prevent accidental touches includes: External fasteners, which can be installed on the bottom of household appliances; An inner movable member that is movable relative to an outer fixed member; The handle is hinged to the outer fixed part and drivenly connected to the inner moving part; when the handle is turned, the handle can drive the inner moving part to move relative to the outer fixed part. It also includes abutting components and oscillating components; One of the abutting component and the swinging component is connected to the outer fixed component, and the other is connected to the inner moving component; One end of the swing component is hinged to the outer fixed component or the inner moving component via the swing component connecting shaft, and the other end is equipped with a roller via the roller connecting shaft. The swing component is provided with a support part. The handle is rotatable, switching between a first position and a second position; In the first position, the angle α between the length direction of the handle and the moving direction of the inner moving part ranges from 70° to 90°. In the second position, the angle α between the length direction of the handle and the moving direction of the inner moving part ranges from 0° to 30°. In the vertical direction: the projection of the abutment is denoted as the first projection area, and the projection between the connecting shaft of the swinging member and the connecting shaft of the roller is denoted as the second projection area; When the handle is rotated from the second position to the first position, the abutment abuts against the support, causing the swinging member to rotate and the roller to move downward, while the first projection area and the second projection area at least partially overlap. When the handle is turned from the first position to the second position, the roller can move upwards.

[0007] In this technical solution, when the roller descends and contacts the ground to lift the household appliance, the angle α between the handle's length direction and the inner moving part's movement direction ranges from 70° to 90°. At this time, the angle between the handle's length direction and the roller's movement direction is also 70° to 90°. Generally, the handle 101 is located on the side closer to the user, so the household appliance is usually dragged towards the user. If the handle is subjected to a collision, i.e., an external force perpendicular to the handle and directed away from the user, the handle will not rotate in the opposite direction, causing the roller to return to its original position. Furthermore, in actual use scenarios, the handle is unlikely to be subjected to an external force perpendicular to the movement direction due to a collision. Therefore, the movable bracket proposed in this solution can reduce the occurrence of the roller returning to its original position due to a collision during use, thus preventing the bottom corner of the household appliance from touching the ground.

[0008] As an optional technical solution in the first aspect, the external fixing member has a first folded edge on one side, and a slot is provided on the first folded edge; when the handle is rotated from the second position to the first position, the handle can be inserted into the slot, and the slot restricts the handle from rotating further. By setting the slot and allowing the handle to be inserted into the slot in the first position, the handle is limited. In addition, the slot only needs to be set on the first folded edge, without the need for additional components, reducing the use of components and helping to improve economy. Optionally, the other side of the external fixing member is provided with a second folded edge; when the handle is rotated from the first position to the second position, the handle can abut against the second folded edge, and the second folded edge restricts the handle from continuing to rotate. When the handle is rotated from the first position to the second position, due to the restricting effect of the second folded edge, the handle will not rotate further, thereby avoiding the handle from jamming due to excessive rotation.

[0009] Optionally, the inner moving member is provided with a third folded edge; the abutting member is a sloped surface provided on the third folded edge; and the supporting part is the upper end surface of the swing member.

[0010] Optionally, the abutting member is a swing arm, one end of which is hinged to an outer fixed member or an inner moving member via an abutting member connecting shaft, and the other end of which is hinged to a roller connecting shaft; the support part is a roller connecting shaft.

[0011] When the handle is in the first position, the axis of the abutment connecting shaft and the axis of the roller connecting shaft form a plane. The angle between this plane and the vertical direction is denoted as β, and the value of β ranges from 3° to 20°. At this time, a stable support can be formed to prevent the roller from returning to its original position after being compressed.

[0012] Optionally, the abutting member is a ramp block, and the supporting part is the upper end surface of the swing member.

[0013] As one possible technical solution in the first aspect, when the handle is in the first position, the length direction of the handle is approximately perpendicular to the movement direction of the inner moving member. When in the perpendicular position, the handle will only rotate when subjected to an external force parallel to the movement direction of the inner moving member and towards the user due to a collision. Since the moving bracket typically moves towards the user during use, the handle will only be subjected to an external force away from the user due to a collision. Therefore, the moving handle in this solution is less likely to cause the bottom corner of the appliance to touch the ground due to a collision. When the handle is in the second position, the length direction of the handle is approximately parallel to the movement direction of the inner moving member.

[0014] As an optional technical solution in the first aspect, the handle is hinged to a connecting rod, and the connecting rod is hinged to the inner moving part; or: the handle is provided with a guide groove, and the inner moving part is equipped with a guide shaft.

[0015] Second, a household appliance, including the anti-accidental touch movable bracket described in the first aspect or any of the technical solutions in the first aspect. Attached Figure Description

Detailed Implementation

[0018] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments.

[0019] The structures, proportions, and sizes illustrated in the accompanying drawings are merely for illustrative purposes and to aid those skilled in the art in understanding and reading the invention. They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the technical content disclosed in this utility model. Furthermore, terms such as "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity and not intended to limit the scope of implementation. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention's implementation.

[0020] In one embodiment, such as Figures 1-9 As shown, this application proposes an anti-accidental touch movable bracket, including an outer fixing member 201, an inner moving member 202, a handle 101, a stop member 301, and a swing member 302. The outer fixing member 201 is used to connect to a household appliance; specifically, the outer fixing member 201 is installed at the bottom of the household appliance.

[0021] The inner movable member 202 is located below the outer fixed member 201, and the inner movable member 202 is movable relative to the outer fixed member 201. In this embodiment, the movable bracket is generally strip-shaped, and the direction of movement of the inner movable member 202 is the same as the length extension direction of the movable bracket.

[0022] The handle 101 is hinged to the outer fixed member 201, meaning that the handle 101 can rotate relative to the outer fixed member 201. The handle 101 is also connected to the inner moving member 202 via a transmission connection. Through this transmission connection, when the handle 101 is rotated, the handle 101 can drive the inner moving member 202 to move relative to the outer fixed member 201.

[0023] Rotating handle 101 allows it to switch between a first position and a second position. In the first position, the angle α between the handle's length direction and the movement direction of the inner moving member 202 ranges from 70° to 90°; in the second position, the angle α ranges from 0° to 30°. When handle 101 is in the first position, rotating it will move it to the second position; similarly, when handle 101 is in the second position, rotating it in the opposite direction will move it to the first position.

[0024] For the abutting member 301 and the swinging member 302, one of them is connected to the outer fixed member 201, and the other is connected to the inner moving member 202. For example, the abutting member 301 can be connected to the outer fixed member 201, in which case the swinging member 302 is hinged to the inner moving member 202. Alternatively, the abutting member 301 can be connected to the inner moving member 202, in which case the swinging member 302 is hinged to the outer fixed member 201. The connection methods of the abutting member 301, the swinging member 302, the outer fixed member 201, and the inner moving member 202 are relatively mature in the existing technology, and will not be elaborated or limited here.

[0025] In this embodiment, one end of the swing member 302 is hinged to the outer fixed member or the inner moving member through the swing member connecting shaft 305, and the other end is equipped with a roller 304 through the roller connecting shaft 303.

[0026] Meanwhile, the swing member 302 is also provided with a support. It should be noted that when the handle 101 is rotated from the second position to the first position, during the rotation, the abutment 301 will abut against the support, thereby causing the swing member 302 to rotate and the roller 304 to move downward (towards the ground). After the roller 304 contacts the ground, it will lift the household appliance connected to the external fixing member 201, and the bottom corner of the household appliance will no longer touch the ground. At this time, the household appliance can be dragged, and the roller 304 rolls along the ground.

[0027] In the vertical direction: the projection of the abutment 301 is denoted as the first projection area, and the projection between the swing member connecting shaft 305 and the roller connecting shaft 303 is denoted as the second projection area. When the handle 101 is in the first position, the first projection area and the second projection area at least partially overlap, that is, in the vertical direction, the support and the abutment 301 can play a supporting role.

[0028] When the handle 101 is rotated from the first position to the second position, the roller 304 can move upward, that is, the household appliance can fall until the bottom corner of the household appliance contacts the ground.

[0029] As an optional implementation, the external fastener 201 has a first folded edge 201-1 on one side, and a slot 201-3 is provided on the first folded edge 201-1.

[0030] When handle 101 is rotated to the first position, handle 101 can be inserted into slot 201-3. Slot 201-3 restricts handle 101 from rotating further, thereby preventing handle 101 from over-rotating and jamming. In addition, slot 201-3 can also play a limiting role.

[0031] Generally, the handle 101 is located on the side closer to the user, so the household appliance is usually dragged towards the user. If the handle is hit by an impact, i.e., subjected to an external force perpendicular to the handle and directed away from the user, the handle will not rotate in the opposite direction, causing the roller to return to its original position. Furthermore, in actual use, the handle is unlikely to experience an external force perpendicular to the direction of movement due to impacts. Therefore, the movable bracket proposed in this solution can reduce the occurrence of rollers returning to their original position due to impacts during use, thus preventing the bottom corner of the household appliance from touching the ground.

[0032] Optionally, the other side of the outer fastener 201 is provided with a second folded edge 201-2. When the handle 101 is rotated from the first position to the second position, the handle 101 can abut against the second folded edge 201-2, and the second folded edge 201-2 restricts the handle 101 from continuing to rotate.

[0033] The first fold 201-1 and the second fold 201-2 can be formed by stamping from the outer fastener 201. By setting the second fold 201-2, the handle 101 can be prevented from jamming due to excessive rotation when rotating from the first position to the second position.

[0034] The following embodiment can be used as a reference for the location of the support: In one embodiment, the inner moving member 202 is provided with a third folded edge 202-1, and the abutting member 301 is a slope surface provided on the third folded edge 202-1. At this time, the supporting part is the upper end surface of the swing member 302.

[0035] In another embodiment, the abutment 301 is a swing arm, one end of which is hinged to the outer fixed member or the inner moving member via the abutment connecting shaft 306, and the other end of which is hinged to the roller connecting shaft 303. In this case, the support part is the roller connecting shaft 303.

[0036] In another embodiment, the abutment 301 is a ramp block, and the support part is the upper end face of the swing member 302.

[0037] In the above embodiments, the installation methods of the abutment 301 and the swing member 302 can all be found in the prior art, and will not be described or limited here.

[0038] It should be noted that when the abutment 301 is a swing arm, when the handle is in the first position, the axis of the abutment connecting shaft and the axis of the roller connecting shaft form a plane, and the angle between this plane and the vertical direction is denoted as β, with β ranging from 3° to 20°. Figure 6 As shown, the swing arm is tilted away from the handle 101, that is, the aforementioned plane is tilted away from the handle 101. When the weight of the household appliance is applied to the movable bracket, the swing arm tilting away from the handle can prevent the swing arm from rotating under pressure, thus preventing the roller 304 from returning to its original position.

[0039] In a preferred embodiment, when the handle 101 is in the first position, the length direction of the handle is approximately perpendicular to the movement direction of the inner moving member 202. When in the perpendicular position, the handle will only rotate when subjected to an external force parallel to the movement direction of the inner moving member and towards the user due to a collision. Since the movable bracket typically moves towards the user during use, the handle will only be subjected to an external force away from the user due to a collision. Therefore, the movable handle in this design is less likely to cause the bottom corner of the appliance to touch the ground due to a collision during use.

[0040] Optionally, when the handle 101 is in the second position, the length direction of the handle is approximately parallel to the movement direction of the inner moving part 202. At this time, the roller 304 falls back, and the bottom corner of the household appliance contacts the ground.

[0041] The transmission connection between the handle 101 and the inner moving part 202 can be implemented in the following two embodiments: In one embodiment, the handle 101 is hinged to a connecting rod 102, which is hinged to the inner moving member 202.

[0042] In another embodiment, the handle 101 is provided with a guide groove 104, and the inner moving part 202 is equipped with a guide shaft 103. The guide shaft 103 is located in the guide groove 104. When the handle 101 is rotated, the guide shaft 103 moves along the guide groove 104.

[0043] This application also proposes a household appliance that includes the anti-accidental touch movable bracket in any of the above embodiments.

[0044] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
