Description

Technical Field

[0001] The utility model relates to the field of transfer tooling, in particular to a mobile device for household appliances with stable support. Background Art

[0002] During the production, transportation and storage of household appliances, their relatively large weight causes certain troubles in the transfer process. There are three ways to move heavier household appliances (such as washing machines or refrigerators): using a transfer forklift, relying entirely on manpower, and using specific transfer tooling. The above transfer tooling has the advantages of being convenient to carry, having a small overall weight, and strong overall pertinence in use.

[0003] During use, the transfer tooling is inserted into the gap between the household appliance and the ground, and then operations are carried out through the transfer tooling. After lifting the household appliance, it is towed for transfer. However, in order to facilitate tilting and towing at the bottom of some household appliances, generally two standing corners (the standing corners are mostly arranged on a reinforcing rib at the bottom) and two rolling wheels, or simply to make up for the strength of a local position at the bottom, a reinforcing rib is added; the above situations have resulted in actual cases where the front and rear heights at the bottom are inconsistent. Then, the transfer tooling with a traditional structure cannot adapt to the non-planar condition of the bottom of the above household appliances. If forced to use, the household appliance will tilt during the transfer process, which is not conducive to the performance of the household appliance and at the same time poses a safety hazard.

[0044] Reference Figures 1 to 16 In one embodiment of the utility model, a household appliance mobile device with a stable support includes:

[0045] The support plate 100 has an installation space 110 on its lower surface along the length direction, and an opening 120 is provided in the thickness of one end of the support plate 100 in the length direction;

[0046] The top block portion 200 includes a top block 210 which is lifted and disposed in the opening 120 , and a first protrusion 211 is disposed on the lower surface of the top block 210 ;

[0047] A plurality of ejector wheel parts 300 are respectively arranged corresponding to the plurality of first protrusions 211, and include a mounting frame 310 hinged to the support plate 100, and a roller 320 is arranged at a free end of the mounting frame 310, wherein the ejector block 210 is located between two of the ejector wheel parts 300;

[0048] A sliding member 400 is slidably disposed in the installation space 110 along the length direction, and a plurality of second protrusions 410 are spaced apart at the bottom of the sliding member 400 in the length direction;

[0049] A fixing seat 500 is disposed at the other end of the supporting plate 100 in the length direction and extends upward;

[0050] The pull member 600 is hinged to the fixing seat 500 at the middle part in the length direction, and the lower end in the length direction is connected to one end of the sliding member 400 near the fixing seat 500 to drive the sliding member 400;

[0051] When the sliding member 400 is in a pushed-in state, the sliding member 400 avoids the ejection block 210 and the ejection wheel portion 300 ; when the sliding member 400 is in a pulled-out state, the sliding member 400 ejects the ejection block 210 and the ejection wheel portion 300 .

[0052] In the present utility model, an installation space 110 is provided along the length direction on the lower surface of the support plate 100. During the use of the household appliance moving device, the upper surface of the support plate 100 directly supports the household appliance. The installation space 110 can be formed synchronously during the processing (such as sheet metal working) of the support plate 100, and the installation space 110 provides an installation basis for the subsequent sliding member 400. An opening 120 is provided in the thickness of one end of the support plate 100 along the length direction, providing a basis for the subsequent top block portion 200. The preferred processing method of the support plate 100 is achieved through raw material plates by processes such as bending and punching.

[0053] The top block portion 200 includes a top block 210 that is vertically arranged in the opening 120. There are various ways for the top block 210 to achieve vertical movement in the thickness direction of the opening 120. For example, a guide groove is provided on the inner wall of the opening 120, and a guide shaft is provided at the corresponding position on the outer periphery of the top block 210, so that the top block 210 can form a sliding connection in the thickness direction of the opening 120. It should be noted that the movement form of the top block 210 is not limited to only the vertical direction, and there can also be a certain displacement in the horizontal direction. In another specific embodiment, the two ends of the top block 210 are respectively hinged with a first link member 220 and a second link member 230. One end of the first link member 220 away from the top block 210 is hinged to the support plate 100, and a first kidney-shaped hole 130 is provided on the support plate 100 corresponding to the second link member 230. One end of the second link member 230 away from the top block 210 is slidably hinged to the first kidney-shaped hole 130. A first protrusion 211 is provided on the lower surface of the top block 210, and the first protrusion 211 is provided corresponding to the subsequent sliding member 400.

[0054] A plurality of ejecting wheel portions 300 are respectively provided corresponding to a plurality of first protrusions 211, including a mounting frame 310 hinged to the support plate 100. A roller 320 is provided at the free end of the mounting frame 310. The top block 210 is located between two ejecting wheel portions 300. It should be noted that the structure of the ejecting wheel portions 300 is not limited to being completely the same. Since the top block 210 is subjected to a large force, the top block 210 is arranged between two ejecting wheel portions 300, thus ensuring the use stability of the household appliance moving device.

[0055] The sliding member 400 is slidably arranged in the installation space 110 along the length direction, and a plurality of second protrusions 410 are arranged at intervals at the bottom of the sliding member 400 in the length direction. The sliding member 400 is not limited to a standard plate shape, and can also have relevant bends, etc. During the sliding process of the sliding member 400, the second protrusion will also move. It should be noted that the structure of the plurality of second protrusions 410 is not limited to being completely consistent. When the sliding member 400 is in the pushed-in state, the sliding member 400 avoids the top block 210 and the ejection wheel portion 300, at which time the ejection wheel portion 300 does not turn out downward, and the top block 210 does not rise. When the sliding member 400 is in the pulled-out state, the sliding member 400 ejects the top block 210 and the ejection wheel portion 300, at which time the ejection wheel portion 300 turns out downward, and the top block 210 rises, thereby completing the lifting of the household appliance and preparing for movement. The above method of swinging out the ejection wheel portion 300 requires a small driving force, thereby reducing the difficulty of manual operation. The sliding member 400 is restricted from coming out of the support plate 100 , and there are various ways to implement this, such as forming a snap-fit ​​structure through the support plate 100 , or restricting the sliding member 400 from coming out through the ejection wheel portion 300 .

[0056] The fixed seat 500 is arranged at the other end of the support plate 100 in the length direction and extends upward. The fixed seat 500 can be an integral structure with the support plate 100, or a subsequent connection structure. The middle part of the pull member 600 in the length direction is hinged to the fixed seat 500, and the lower end in the length direction is connected to the end of the sliding member 400 near the fixed seat 500 to drive the sliding member 400. The pull member 600 does not limit the driving method of the sliding member 400. For example, when the pull member 600 is pressed down, the sliding member 400 is pulled out, and when the pull member 600 is turned up, the sliding member 400 is pushed in; or when the pull member 600 is pressed down, the sliding member 400 is pushed in, and when the pull member 600 is turned up, the sliding member 400 is pulled out.

[0057] In summary, a plurality of ejector wheel portions 300 are arranged in the support plate 100, and the ejector wheel portions 300 can perform a swinging motion. An opening 120 is arranged on the support plate 100, and a top block portion 200 is movably arranged in a thickness direction of the opening 120; the driving of the sliding member 400 can be achieved by operating the pull member 600, and the force required in this process is relatively small, and the possibility of abnormal swinging of the entire household appliance mobile device is relatively low; when the sliding member 400 is in a pushed-in state, the sliding member 400 avoids the top block 210 and the ejector wheel portion 300, and at this time, the ejector wheel portion 300 does not flip downward, and the top block 210 does not rise. When the sliding member 400 is in the pulled-out state, the sliding member 400 pushes out the ejector block 210 and the ejector wheel portion 300. At this time, the ejector wheel portion 300 flips downward and the ejector block 210 rises, thereby completing the lifting of the household appliance and preparing for movement. The rise of the ejector block 210 can adapt to the situation where the bottom height of some household appliances is inconsistent. The above design achieves the advantages of simple structure and reliable operation.

[0058] In one embodiment, the two ends of the top block 210 are respectively hinged with a first connecting rod 220 and a second connecting rod 230, the end of the first connecting rod 220 away from the top block 210 is hinged to the support plate 100, and a first waist-shaped hole 130 is provided on the support plate 100 corresponding to the second connecting rod 230, and the end of the second connecting rod 230 away from the top block 210 is slidably hinged to the first waist-shaped hole 130.

[0059] In this embodiment, the first link member 220 and the second link member 230 are hinged at both ends of the top block 210. When the top block 210 is in the upper state, the first link member 220 and the second link member 230 form a stable support for the top block 210. The end of the first link member 220 away from the top block 210 is hinged to the support plate 100. The support plate 100 is provided with a first waist-shaped hole 130 corresponding to the second link member 230, and the end of the second link member 230 away from the top block 210 is slidably hinged to the first waist-shaped hole 130, and the end of the second link member 230 away from the top block 210 can slide in the first waist-shaped hole 130 and rotate at the same time. The first link member 220 mainly limits the range of motion of the top block 210, and the activity characteristics of the second link member 230 ensure that the top block 210 can complete the rising action. The lower surface of the top block 210 is provided with a first protrusion 211, and the first protrusion 211 is provided corresponding to the subsequent sliding member 400.

[0060] In one embodiment, second waist-shaped holes 430 are provided at both ends of the sliding member 400 in the width direction corresponding to the mounting frame 310 .

[0061] In this embodiment, the mounting frame 310 is hinged on the support plate 100 , and the movement of the sliding member 400 can be restricted by providing a second waist-shaped hole 430 on the sliding member 400 .

[0062] In one embodiment, the ejector wheel portion 300 further includes an elastic member, and the elastic member is connected to the mounting bracket 310 in the direction in which the mounting bracket 310 presses against the support plate 100.

[0063] In this embodiment, the form of the elastic member can be diverse, for example, a torsion spring. In a typical structure, the mounting bracket 310 includes a frame body and a mounting shaft. The mounting shaft is fixed to the support plate 100, the frame body is hinged to the mounting shaft, and the torsion spring is disposed on the mounting shaft as the elastic member, and presses the mounting bracket 310 in the direction of the support plate 100, so that in the free state, the ejector wheel portion 300 will not sag naturally.

[0064] Refer to Figure 15 In one embodiment, a soft cushion layer 140 is provided at one end in the length direction of the support plate 100.

[0065] In this embodiment, considering that during use, one end in the length direction of the support plate 100 is the insertion direction, through the arrangement of the soft cushion layer 140, it can avoid the impact damage of the support plate 100 to the outside during use. The material of the soft cushion layer 140 can be rubber or plastic, etc., and is not specifically limited.

[0066] Refer to Figures 1 to 13 In one embodiment, an auxiliary support seat 510 is connected to the lower part of the fixed seat 500. Wherein, when the sliding member 400 is in the pushed-in state, the bottom surface of the auxiliary support seat 510 is flush with or extends beyond the bottom surface of the overall support plate 100 and the sliding member 400.

[0067] In this embodiment, considering that the weight of household appliances is relatively large, during the lifting process, the force received at the position of the fixed seat 500 is relatively large, so the support plate 100 and the sliding member 400 are prone to compressive deformation. Through the position setting and height setting of the auxiliary support seat 510, during the process of lifting the household appliances, the auxiliary support seat 510 bears most of the force, thereby protecting the support plate 100 and the sliding member 400.

[0068] Refer to Figures 14 to 16 In one embodiment, one ejector wheel portion 300 is provided at each of the two ends in the length direction of the support plate 100.

[0069] In this embodiment, it is limited that one ejector wheel portion 300 is provided at each of the two ends in the length direction of the support plate 100, and during the lifting and transfer processes, the use stability of the household appliance moving device is improved.

[0070] In one embodiment, the number of the ejector wheel portions 300 is 5 to 7.

[0071] In the foregoing embodiments, the number of the ejecting wheel parts 300 is not limited, and in the least case, there are two. In this embodiment, by limiting the number of the ejecting wheel parts 300, the use process of the household appliance moving device is made more stable, and the processing difficulty is not increased significantly. Especially when the number of the ejecting wheel parts 300 is increased, when a single ejecting wheel part 300 has a problem, removing it does not affect the overall use.

[0072] In one embodiment, a scale is arranged on the upper surface of the support plate 100 along the length direction.

[0073] In this embodiment, considering that in some fine construction conditions, it is necessary to limit the overall insertion degree of the household appliance moving device. A scale is arranged on the upper surface of the support plate 100 along the length direction, so as to give a direct guidance numerically.

[0074] In one embodiment, at least one end of the upper end of the operating member 600 in the width direction is provided with an inward shrinkage opening along the length direction.

[0075] In this embodiment, considering that the action of turning the operating member 600 upwards is generally operated by hand, and the action of pressing the operating member 600 downwards is generally operated by foot. By setting the inward shrinkage opening, while ensuring that the width of the operating member 600 is not too small, it is convenient for hand holding operation. The overall width dimension of the operating member 600 is preferably selected to be 7 to 10 cm. At least one end of the upper end of the operating member 600 in the width direction is provided with an inward shrinkage opening along the length direction, so that the width of the operating member 600 is reduced locally, which is convenient for hand holding.

[0076] Referring to Figures 14 to 16 , in one embodiment, when the sliding member 400 is in the pushed-in state, the roller 320 is exposed at the bottom end of the whole of the support plate 100 and the sliding member 400, and the roller 320 is separated from the sliding member 400.

[0077] In this embodiment, by limiting the state of the ejecting wheel part 300 when the sliding member 400 is in the pushed-in state, the use effect of the household appliance moving device is improved. Specifically, when in the pushed-in state, first, the roller 320 is separated from the sliding member 400 and can rotate normally; second, the roller 320 is exposed at the bottom end of the whole of the support plate 100 and the sliding member 400, so that the roller 320 can reduce the difficulty of dragging the household appliance moving device. Specifically, there are various ways to achieve the above structural characteristics of the ejecting wheel part 300. For example, a fold angle is formed in the length direction of the mounting frame 310 (including parallel segments and a fold angle segment with an obtuse angle between them). Thus, when the parallel segment contacts the sliding member 400, due to the support of the fold angle segment, the roller 320 is exposed at the bottom end of the whole of the support plate 100 and the sliding member 400, and is separated from the sliding member 400.

[0078] Reference Figures 14 to 16 In one embodiment, a through hole 420 is provided at a position of the sliding member 400 corresponding to the roller 320 .

[0079] In this embodiment, in order to achieve smooth rotation of the roller 320, the diameter of the roller 320 is increased, and the thickness of the household appliance moving device is generally small. At this time, a through hole 420 is set at the position corresponding to the roller 320 on the sliding member 400 and the support plate 100, and the length direction of the through hole 420 is consistent with the length direction of the roller 320. Then, when the roller 320 has a larger diameter, there is also space for storage.

[0080] In summary, the utility model provides a stable household appliance mobile device, wherein a plurality of ejector wheel portions 300 are arranged in the support plate 100, the ejector wheel portions 300 can swing, an opening 120 is arranged on the support plate 100, and a top block portion 200 is movably arranged in the thickness direction of the opening 120; the driving of the sliding member 400 can be achieved by operating the pull member 600, the force required in this process is small, and the possibility of abnormal swinging of the entire household appliance mobile device is low; when the sliding member 400 is in a pushed-in state, the sliding member 400 avoids the top block 210 and the ejector wheel portion 300, and at this time, the ejector wheel portion 300 does not flip downward, and the top block 210 does not rise. When the sliding member 400 is in the pulled-out state, the sliding member 400 pushes out the ejector block 210 and the ejector wheel portion 300. At this time, the ejector wheel portion 300 flips downward and the ejector block 210 rises, thereby completing the lifting of the household appliance and preparing for movement. The rise of the ejector block 210 can adapt to the situation where the bottom height of some household appliances is inconsistent. The above design achieves the advantages of simple structure and reliable operation.
