[0018] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0019] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediary component present. Conversely, when a component is said to be "directly" connected to another component, there is no intermediary component.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] like Figure 1 and Figure 6 As shown, a movable bracket 10 includes a support mechanism 100. The bottom of the support mechanism 100 is equipped with a caster wheel assembly 200. The support mechanism 100 includes at least two relatively sliding support platforms 110, and an adjustment mechanism 300 is provided between every two adjacent support platforms 110 to drive the two support platforms 110 closer together or further apart, thereby adjusting the load-bearing width between the two support platforms 110. Specifically, in this application, four support platforms 110 are provided, located at the four corners of the movable bracket 10. During use, by pushing the support platforms 110, the two oppositely positioned support platforms 110 move relative to each other, while the adjustment mechanisms 300 extend towards the support platforms 110, thus changing the load-bearing width of the entire movable bracket 10.

[0022] Furthermore, the adjustment mechanism 300 includes a telescopic sleeve 310 and a telescopic rod 320. The telescopic sleeve 310 is slidably disposed on the support platform 110, and the telescopic rod 320 is slidably disposed within the telescopic sleeve 310 to achieve adjustment of the width between two adjacent support platforms 110. The support base 112 is provided with a groove 1125 for mounting the telescopic sleeve 310. Limiting blocks 1126 are provided along the length direction of the groove 1125. The limiting blocks 1126 are located on both sides of the groove 1125 to limit the sliding position of the telescopic sleeve 310 and prevent it from falling off.

[0023] Specifically, the telescopic sleeve 310 includes a first telescopic sleeve 311 and a second telescopic sleeve 312, and the first telescopic sleeve 311 and the second telescopic sleeve 312 are connected by a telescopic rod 320.

[0024] In Example 1, when it is necessary to increase the width of the bracket, the support platform 110 connected to the first telescopic sleeve 311 and the second telescopic sleeve 312 is pushed, so that the first telescopic sleeve 311 and the second telescopic sleeve 312 gradually slide out of the slide groove 1125 of the support platform 110. At this time, the width between adjacent support platforms 110 increases to a preset distance. When the width between the support platforms 110 is still insufficient to meet the usage requirements, the adjacent support platforms 110 are pulled further. When the first telescopic sleeve 311 and the second telescopic sleeve 312 abut against the limiting block 1126, the first telescopic sleeve 311 and the second telescopic sleeve 312 cannot slide out of the slide groove 1125. Then, under the action of external pulling force, the first telescopic sleeve 311 and the second telescopic sleeve 312 are pulled further out of the telescopic rod 320, increasing the distance between the first telescopic sleeve 311 and the second telescopic sleeve 312, thereby continuing to adjust the width between the two adjacent support platforms 110. When the first telescopic sleeve 311 and the second telescopic sleeve 312 are stretched to the preset position, the inner telescopic sleeve limiting part abuts against the telescopic rod limiting part, preventing the first telescopic sleeve 311 and the second telescopic sleeve 312 from being pulled out of the telescopic rod 320. At this time, the width between the support platforms 110 reaches its maximum value.

[0025] In Example 2, when the width of the bracket needs to be increased, the first telescopic sleeve 311 and the second telescopic sleeve 312 at both ends of the telescopic rod 320 are pulled to move the first telescopic sleeve 311 and the second telescopic sleeve 312 in opposite directions. When the first telescopic sleeve 311 and the second telescopic sleeve 312 are stretched to the preset position, the inner telescopic sleeve limiting part abuts against the telescopic rod limiting part, so that the first telescopic sleeve 311 and the second telescopic sleeve 312 can no longer be pulled out from the telescopic rod 320. If the width between the support platforms 110 cannot meet the usage requirements, the support platform 110 connected to the first telescopic sleeve 311 and the second telescopic sleeve 312 is pushed to gradually slide the first telescopic sleeve 311 and the second telescopic sleeve 312 out of the slide groove 1125 of the support platform 110 until the first telescopic sleeve 311 and the second telescopic sleeve 312 abut against the limiting block 1126. At this time, the width between the support platforms 110 reaches the maximum value.

[0026] like Figure 2 , Figure 3 and Figure 4As shown, the support platform 110 further includes a support frame 111 and a support base 112. The support frame 111 is fixedly or detachably installed on the support base 112. Specifically, the support frame 111 is provided with a plurality of first buckles 1111, first slots 1112, and first screw holes 1113. The support base 112 is provided with a plurality of second buckles 1121, second slots 1122, and second screw holes 1123. The first buckles 1111 are adapted to the second slots 1122, and the second buckles 1121 are adapted to the first slots 1112. The first screw hole 1113 coincides with the second screw hole 1123. During installation, the first buckle 1111 is placed into the second slot 1122, and the second buckle 1121 is placed into the first slot 1112, so that the support frame 111 and the support base 112 can be fastened together. When the support frame 111 and the support base 112 are fastened together, the first screw hole 1113 coincides with the second screw hole 1123. Then, it can be fixed by screw connection. In this utility model, by adding screw fixation on the basis of snap connection, the stability and firmness of the structure are greatly improved.

[0027] Furthermore, in order to improve the strength and toughness of the overall structure, a reinforcing rib 1114 is provided on the inner bottom side of the support frame 111, and the reinforcing rib 1114 is integrally formed with the support frame 111. By adopting an integral forming process, this application can effectively save materials, reduce production costs, and improve production efficiency.

[0028] In addition, a load-bearing tray 113 is provided at the top of the support frame 111. In this application, the load-bearing tray 113 is made of aluminum alloy. After production, a micro-rough surface is formed on the load-bearing tray 113 by sandblasting, followed by anodizing treatment to increase surface hardness and wear resistance, while also providing a certain anti-slip effect to prevent items from falling off during movement and improve safety during use. The load-bearing tray 113 can also be made of silicone material, which can provide a certain cushioning effect when items are placed on the tray.

[0029] like Figure 5As shown, further, the caster assembly 200 includes a caster mounting base 210 and a caster 220. The caster 220 is installed inside the caster mounting base 210, and the caster mounting base 210 is detachably installed on the bottom of the support base 112. Specifically, the caster mounting base 210 is provided with a plurality of third buckles 211, and the support base 112 is provided with a plurality of third slots 1124. The number of third buckles 211 and the number of third slots 1124 are the same and correspond one-to-one. During installation, the third buckles 211 are simply inserted into the third slots 1124 to connect and fix the device, making installation convenient, time-saving, and labor-saving. The caster 220 is installed inside the caster mounting base 210, which allows the caster 220 to rotate 360 ​​degrees on a horizontal plane. This design indicates that the bracket can easily move in any direction without needing to lift the device and adjust its direction as required when using fixed wheels.

[0030] Furthermore, the movable bracket 10 also includes adjustable support feet 400. Each support foot 400 includes a support body 410 with internal threads on its inner side and external threads on the outer layer of the caster wheel mounting base 210. The support body 410 and the caster wheel mounting base 210 are fixed together by these threads, and the caster wheel 220 is lifted off the ground when the support foot 400 is lowered. When an appliance needs to be fixed in one position for a long time (such as when a washing machine vibrates violently during the spin cycle), the support body 410 can be rotated to extend downwards until the entire movable bracket 10 is lifted, causing the caster wheel 220 to leave the ground. In this way, the movable bracket 10 directly contacts the ground through the support feet 400, eliminating the possibility of movement due to vibration and improving the stability of the support.

[0031] Furthermore, the bottom of the support body 410 is provided with an anti-slip pad 420, which is made of either rubber or silicone. The anti-slip pad 420 increases friction with the ground or tabletop and provides cushioning protection, further improving the stability and safety of the electrical appliances.

[0032] like Figure 5 , Figure 7 and Figure 8As shown, further, a limiting protrusion 411 is provided on the outer side of the support body 410, and a stop 412 cooperates with the limiting protrusion 411. A limiting member 1127 is provided on the side of the support base 112 near the support body 410. When the support foot 400 rotates to a preset position, the limiting protrusion 411 and the stop 412 abut against the preset position of the limiting member 1127, so that the support foot 400 cannot continue to rotate. Specifically, the limiting member 1127 is provided with a first abutting surface 11271, a second abutting surface 11272, a third abutting surface 11273, and a fourth abutting surface 11274. A gentle protrusion exists between the first abutting surface 11271 and the second abutting surface 11272. The first abutting surface 11271 and the second abutting surface 11272 respectively cooperate with the limiting protrusion 411. The third abutting surface 11273 and the fourth abutting surface 11274 respectively cooperate with the stop member 412. In this application, when it is necessary to fix the bracket... When the rotating support body 410 moves closer to the ground, during the rotation of the support body 410, the limiting protrusion 411 first slides on the second abutment surface 11272, then slides past the gentle protrusion and enters the first abutment surface 11271. At this time, the stop 412 and the third abutment surface 11273, and the limiting protrusion 411 and the side of the gentle protrusion close to the first abutment surface 11271 abut against each other, which plays a certain limiting role on the support foot 400 and effectively prevents the support foot 400 from continuing to rotate. At this time, the support foot 400 contacts the ground and the caster wheel 220 leaves the ground. When the bracket needs to be moved, the rotating support body 410 moves away from the ground, and the limiting protrusion 411 slides from the first abutment surface 11271 over the gentle protrusion and enters the second abutment surface 11272. The stop member 412 separates from the third abutment surface 11273 until the stop member 412 abuts against the fourth abutment surface 11274, so that the support foot 400 can no longer rotate. At this time, the caster wheel 220 contacts the ground.

[0033] like Figure 9 As shown, when using this application, the user first adjusts the distance between the support platforms 110 according to the width of the bottom of the appliance, so that its bearing width matches the width of the bottom of the appliance. Then, the appliance is lifted and placed on the load-bearing tray 113. When it needs to be moved, the support body 410 can be rotated to retract away from the ground until the entire movable bracket 10 is raised to a preset height, so that the casters 220 contact the ground, and it can be easily pushed, which is convenient, quick, and saves time and effort. When it needs to be parked for a long time, the support body 410 is rotated to extend downward until the entire movable bracket 10 is lifted up, so that the casters 220 leave the ground, and it can be supported by the support feet 400.

[0034] When storage is required, the support platform 110 is pushed or pulled inward, causing the two opposing support platforms 110 to move closer together until the telescopic rod 320 retracts into the telescopic sleeve 310. Simultaneously, the telescopic sleeve 310 slides completely into the slide groove 1125, thereby retracting the entire support mechanism 100 for easy storage. It should be noted that in the stored state, the limiting protrusion 411 is away from the limiting member 1127, and the stop member 412 is located near the side of the other support foot 400 and is positioned opposite to the stop member 412 of the other support foot 400, thus making the two adjacent support feet 400 symmetrical and reducing space occupation.

[0035] Thus, a movable bracket 10, through the coordinated arrangement of a support mechanism 100, a caster wheel assembly 200, and an adjustment mechanism 300, overcomes the limitations of existing fixed-width brackets. The support mechanism 100 includes at least two relatively sliding support platforms 110. With the help of the adjustment mechanism 300, the width of the support platforms 110 can be adjusted, allowing the movable bracket to adapt to appliances of different widths, achieving a multi-purpose effect, reducing user purchase costs, and demonstrating strong practicality. It can meet the load-bearing requirements of different appliances, providing users with a better user experience. Furthermore, the structure is stable and robust, with strong load-bearing capacity, improving the safety of appliances during movement and parking. It also saves time and effort during movement, without damaging the ground or tabletop, thus meeting user needs.

[0036] The options described in the above method embodiments are also applicable to this embodiment, and will not be detailed here. The remaining contents of this utility model embodiment can be referred to the contents of the above method embodiments, and will not be repeated in this embodiment.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
