Description

Technical Field

[0001] This application relates to the technical field of washing machines, and particularly relates to a fixing structure for transporting a washing drum and a washing machine. Background Art

[0002] The washing drum of a current washing machine includes an outer drum and an inner drum structure. The inner drum is driven by a motor and can rotate during operation to provide a driving force for washing. The outer drum is fixed, providing support for the inner drum and a closed cavity for storing water. During operation, the inner drum transmits vibrations to the outer drum. Therefore, to maintain the stability of the washing machine, the existing outer drum is generally installed in the washing machine frame through structures such as springs and elastic telescopic cylinders, and the springs and elastic telescopic cylinders are used to absorb the vibrations of the outer drum during operation. In a washing machine, the outer drum is actually a movable structure. During the transportation of the washing machine when it leaves the factory, if it encounters relatively large vibrations, the washing drum will vibrate violently, and there is a risk of damage to the internal structures of the washing drum hitting each other. Therefore, when the existing washing machine leaves the factory, transportation bolts are usually used to completely lock the washing drum in the frame, and the transportation bolts can be removed during installation for normal use.

[0003] The transportation bolts only play their functional roles during the transportation of the washing machine. Therefore, after installing and removing the transportation bolts, users generally can only discard them. Even if the transportation bolts are put away, they may be forgotten due to the passage of time. When users need to move or relocate the washing machine, they usually directly transfer the washing machine without fixing the washing drum because they cannot find the transportation bolts, and there is a risk of damage to the internal structures of the washing drum hitting each other during this process. Summary of the Utility Model

[0004] The purpose of the embodiments of the present utility model is to provide a fixing structure for transporting a washing drum and a washing machine, which can solve the above problems existing in the prior art.

[0005] To achieve the above object, the present application adopts the following technical solutions:

[0006] On the one hand, a fixing structure for transporting a washing drum is provided, including:

[0007] A frame;

[0008] A washing drum, installed in the frame, with a fixing seat provided on the outer wall of the washing drum, and a fixing hole provided on the fixing seat;

[0009] The fixing component includes a support cylinder, a locking pin and a control rod. The two ends of the support cylinder are respectively a first end and a second end. The first end is fixed to the frame, and the second end extends towards the direction where the fixed seat is located. The locking pin is telescopically installed in the support cylinder and can extend and retract from the second end. The locking pin has a receiving hole extending axially, and the side wall of the receiving hole is provided with a first sliding groove and a first clamping groove. The first sliding groove extends axially in the locking pin, and the first clamping groove communicates with one end of the first sliding groove close to the first end. The two ends of the control rod are respectively a control end and a connecting end. The control end is located outside the first end, and the connecting end extends into the receiving hole through the inner cavity of the support cylinder. A clamping post is arranged on one side of the connecting end. By rotating the control rod, the clamping post can be placed in the first sliding groove or the first clamping groove. When the clamping post is placed in the first clamping groove, the control rod can drag the locking pin to extend and retract relative to the support cylinder, so that the locking pin is inserted into or disengaged from the fixing hole. When the clamping post is placed in the first sliding groove, the control rod can slide freely relative to the locking pin.

[0010] Optionally, the control rod includes a connected first rod portion and a second rod portion. The diameter of the first rod portion matches the inner cavity size of the support cylinder, and it is slidably installed in the support cylinder. The diameter of the second rod portion matches the aperture size of the receiving hole, and it extends into the receiving hole. The clamping post is arranged on the second rod portion.

[0011] Optionally, an installation groove is provided on the inner side of the support cylinder, and a torsion spring is installed in the installation groove. An axially extending second sliding groove is provided on the side of the second rod portion. One end of the torsion spring is fixed to the support cylinder, and the other end extends into the second sliding groove. The torsion spring provides a torsion force to the control rod to automatically snap the clamping post into the first clamping groove.

[0012] Optionally, a second clamping groove is further provided on the side wall of the receiving hole. The second clamping groove communicates with one end of the first sliding groove far from the first end. The second clamping groove and the first clamping groove are located on the same side of the first sliding groove. When the clamping post is placed in the second sliding groove, the control rod locks the locking pin at the position where it retracts into the support cylinder.

[0013] Optionally, an inner retaining ring is provided at the second end of the support cylinder, and an outer retaining ring is connected to one end of the locking pin close to the first end. The inner retaining ring can limit the outer retaining ring within the support cylinder to prevent the locking pin from completely disengaging from the support cylinder.

[0014] Optionally, the side wall of the outer retaining ring is provided with a rib, and the inner wall of the support cylinder is provided with an axially extending anti-rotation groove adapted to the rib, and the rib is snapped into the anti-rotation groove to limit the rotation of the locking pin.

[0015] Optionally, the first end of the support cylinder is provided with an outwardly protruding first shoulder, and the outer wall of the support cylinder is provided with a threaded portion near the first shoulder, and a fixing nut is installed on the threaded portion, and the support cylinder is fixed to the frame by the clamping of the fixing nut and the first shoulder.

[0016] Optionally, a locking member is further included, and the locking member includes a connected nut portion and a limit ring portion; the control rod is provided with a spaced second shoulder and a third shoulder at the control end, and the limit ring portion is restricted between the second shoulder and the third shoulder; the first shoulder is provided with an external thread, and the nut portion is threadedly connected to the first shoulder to lock the control rod to the support cylinder.

[0017] Optionally, a handle is connected to the control end of the control rod.

[0018] On the other hand, a washing machine is provided, including the above-mentioned laundry tub transportation and fixing structure.

[0019] The beneficial effects of the present application are as follows: The present utility model provides a laundry tub transportation and fixing structure, including a fixing component fixed to the frame, and the fixing component includes a telescopic locking pin and a control rod. The user can control the telescopic movement of the locking pin through the control rod, so that it is inserted into the fixing seat of the laundry tub to fix the laundry tub, or it is disengaged from the fixing seat to release the laundry tub. Since the fixing component in this solution is directly fixed in the frame, it still remains stationary in the washing machine after unlocking, and the user does not need to consider the problem of separately storing it after removal. Therefore, when the washing machine still needs to be moved after use, the locking pin of the fixing component is extended again to lock the laundry tub, and the laundry tub can be protected.

[0020] Importantly, this solution provides a control rod inserted from the first end of the support cylinder to control the locking pin located inside the frame. When the user locks or unlocks the laundry tub, only the rear shell of the washing machine needs to be disassembled, and then the control rod located outside the frame can be manipulated, without having to reach the hand or tool into the inside of the frame. Therefore, it has the advantage of being convenient for the user to perform locking and unlocking operations. Moreover, after the locking pin is pulled back into the support cylinder by the control rod, a part of the control rod can be received in the receiving hole of the locking pin, avoiding the problem that the control rod protrudes too far outside the frame and affects the installation of the rear shell.

[0035] To make the technical problems solved by this application, the technical solutions adopted, and the achieved technical effects clearer, the following further details the technical solutions of the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of this application.

[0036] In the description of this application, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific situations.

[0037] In this application, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature may include direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "over", and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or simply means that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "under", and "beneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the horizontal height of the first feature is lower than that of the second feature.

[0038] The laundry drum of the current washing machine includes an outer drum and an inner drum structure. The inner drum is driven by a motor and can rotate during operation to provide the driving force for laundry. The outer drum is fixed, providing support for the inner drum and a closed cavity for water storage. During operation, the inner drum transmits vibrations to the outer drum. Therefore, to maintain the stability of the washing machine, the existing outer drum is generally installed in the washing machine frame through structures such as springs and elastic telescopic cylinders, and the springs and elastic telescopic cylinders are used to absorb the vibrations of the outer drum during operation. In a washing machine, the outer drum actually belongs to a movable structure. During the transportation of the washing machine from the factory, if it encounters relatively large vibrations, the laundry drum will vibrate violently, and there is a risk of damage to the internal structures of the laundry drum hitting each other. Therefore, when the existing washing machine leaves the factory, transportation bolts are usually used to completely lock the laundry drum in the frame, and the transportation bolts can be removed during installation for normal use.

[0039] The transportation bolts only play their functional roles during the transportation of the washing machine. Therefore, after installing and removing the transportation bolts, users generally can only discard them. Even if the transportation bolts are put away, they may be forgotten due to the passage of time. When users need to move or relocate the washing machine, they usually directly transport the washing machine without fixing the laundry drum because they cannot find the transportation bolts. There is a risk of damage to the internal structures of the laundry drum hitting each other during this process.

[0040] Referring to Figure 1-11 , to overcome the above technical problems, this embodiment provides a transportation fixing structure for the laundry drum, including a frame 2, a laundry drum 1, and a fixing component 3. A fixing seat 11 with a fixing hole 111 is provided on the outer wall of the laundry drum 1, and a reusable fixing component 3 is provided inside the frame 2. Before transporting the washing machine, the laundry drum 1 can be locked by using the fixing component 3 to provide protection. When installing the washing machine, the fixing component 3 can be directly unlocked. Since the fixing component 3 in this solution is directly fixed in the frame 2, it remains in the washing machine without moving after being unlocked, and users do not need to consider the problem of separately storing it after removal. Therefore, when the washing machine still needs to be transported after use, the fixing component 3 can be released again to lock the laundry drum 1, thereby protecting the laundry drum 1.

[0041] In the specific solution of the fixing structure of the washing tub 1 in this embodiment, the washing tub 1 is installed in the frame 2. A fixing seat 11 is provided on the outer wall of the washing tub 1, and a fixing hole 111 is provided on the fixing seat 11. The fixing component 3 includes a support cylinder 31, a locking pin 32 and a control rod 33. The two ends of the support cylinder 31 are respectively a first end and a second end. The first end is fixed to the frame 2, and the second end extends towards the direction where the fixing seat 11 is located. The locking pin 32 is telescopically installed in the support cylinder 31, and the locking pin 32 can be telescoped from the second end. The locking pin 32 has a receiving hole 321 extending axially. A first chute 322 and a first card slot 323 are provided on the side wall of the receiving hole 321. The first chute 322 extends axially in the locking pin 32, and the first card slot 323 communicates with one end of the first chute 322 close to the first end. The two ends of the control rod 33 are respectively a control end and a connection end. The control end is located outside the first end, and the connection end extends into the receiving hole 321 through the inner cavity of the support cylinder 31. A clamping post 3321 is provided on one side of the connection end. By rotating the control rod 33, the clamping post 3321 can be placed in the first chute 322 or the first card slot 323. When the clamping post 3321 is placed in the first card slot 323, the control rod 33 can drag the locking pin 32 to telescopically move relative to the support cylinder 31, so that the locking pin 32 is inserted into or disengaged from the fixing hole 111. When the clamping post 3321 is placed in the first chute 322, the control rod 33 can freely slide relative to the locking pin 32.

[0042] Based on the fixing structure of the washing tub 1 in this embodiment, at the time of leaving the factory, the locking pin 32 is inserted into the fixing hole 111 of the fixing seat 11 to fix the washing tub 1, that is Figure 2 in the state shown, to prevent the problem that the parts in the washing machine are damaged due to excessive vibration of the washing tub 1 during transportation. When the user installs, after the user opens the rear cover 42 of the washing machine shell, the control rod 33 is pulled through the control end of the control rod 33, so that the control rod 33 pulls the locking pin 32 away from the fixing seat 11. Then the control rod 33 is rotated to place the clamping post 3321 on the control rod 33 in the first chute 322 in the locking pin 32. Then the control rod 33 is pushed inwards. Since there is no axial position between the clamping post 3321 on the control rod 33 and the locking pin 32 at this time, the locking pin 32 remains stationary at this time, and the control rod 33 can be pushed back into the support cylinder 31 again, that is Figure 3The state shown. When the user needs to move the washing machine and needs to relock the washing tub 1, just pull the control rod 33 outwards again. After aligning the latch post 3321 with the side of the first card slot 323, twist the control rod 33 to place it in the first card slot 323, and then push the control rod 33 in again. At this time, the locking bolt 32 can be pushed out through the control rod 33, and the locking bolt 32 is inserted into the fixed seat 11 to fix the washing tub 1.

[0043] The advantage of the cooperation between the control rod 33 and the locking bolt 32 in this solution realized through structures such as the latch post 3321, the first chute 322, and the first card slot 323 is as follows: Refer to Figure 1 , in the structure of the washing machine, the frame 2 serves as the main internal support. The washing tub 1 is installed inside the frame 2. To protect the internal structure of the washing machine and make the washing machine beautiful, the washing machine further includes a housing 4 installed outside the frame 2. The housing 4 includes a housing main body 41 and a housing rear cover 42 installed behind the housing main body 41. The housing rear cover 42 can be disassembled separately, and the gap between the housing 4 and the frame 2 is generally relatively small. The purpose of extending the control end of the control rod 33 outside the frame 2 in this solution is to facilitate user operation, that is, the control end can be directly accessed after opening the housing rear cover 42 without having to disassemble the frame 2. However, the control end is located between the housing 4 and the frame 2. When the locking bolt 32 is pulled back and retracted using the control rod 33, the distance that the control rod 33 extends out of the frame 2 will inevitably increase. At this time, it is difficult to avoid the control rod 33 interfering with the installation of the housing rear cover 42. Therefore, the receiving hole 321 provided in the locking bolt 32 of this solution can exactly be used to receive the re-pushed control rod 33, and at the same time, the problem of the control rod 33 pushing the locking bolt 32 out again is avoided by using the avoidance of the first chute 322.

[0044] In summary, this solution provides a control rod 33 inserted from the first end of the support cylinder 31 to control the locking bolt 32 located inside the frame 2. When the user locks or unlocks the washing tub 1, just disassemble the rear shell of the washing machine, and then the control rod 33 located outside the frame 2 can be manipulated without having to put the hand or tool into the frame 2. Therefore, it has the advantage of facilitating the user to perform locking and unlocking operations. Moreover, after pulling the locking bolt 32 back into the support cylinder 31 using the control rod 33, a part of the control rod 33 can also be received by the receiving hole 321 of the locking bolt 32 to avoid the problem that the control rod 33 protrudes too long outside the frame 2 and affects the installation of the housing rear cover 42.

[0045] In one embodiment, the control rod 33 includes a first rod portion 331 and a second rod portion 332 connected to each other. The diameter of the first rod portion 331 matches the inner cavity size of the support cylinder 31, and it is slidably mounted in the support cylinder 31. The diameter of the second rod portion 332 matches the aperture size of the receiving hole 321, and it extends into the receiving hole 321. The locking post 3321 is provided on the second rod portion 332.

[0046] The diameter of the first rod portion 331 matches the inner cavity size of the support cylinder 31, which ensures that the first rod portion 331 can smoothly slide within the support cylinder 31, making the control rod 33 more stable and reliable when pulling the locking bolt 32, and improving the stability of the overall structure. The diameter of the second rod portion 332 matches the aperture size of the receiving hole 321. This design enables the second rod portion 332 to smoothly extend into the receiving hole 321 and cooperate with structures such as the locking post 3321, the first chute 322, and the first card slot 323 inside the locking bolt 32.

[0047] In one embodiment, referring to Figures 5-7 , an installation groove 314 is provided on the inner side of the support cylinder 31, and a torsion spring 37 is installed in the installation groove 314. An axially extending second chute 3311 is provided on the side of the second rod portion 332. One end of the torsion spring 37 is fixed to the support cylinder 31, and the other end extends into the second chute 3311. The torsion spring 37 provides a torsion force to the control rod 33, causing the locking post 3321 to automatically snap into the first card slot 323.

[0048] The second chute 3311 is provided on the side of the second rod portion 332, enabling one end of the torsion spring 37 to snap into the second chute 3311. At the same time, when pushing and pulling the control rod 33, the control rod 33 can axially move relative to the torsion spring 37. The design of the torsion spring 37 enhances the stability and reliability of the structure. Due to the presence of the torsion spring 37, after locking the washing tub 1 during transportation, even in the case of external vibrations or interference, the locking post 3321 can maintain a stable position in the first card slot 323, and is not prone to falling off or shifting, enabling the locking bolt 32 to stably lock the fixed seat 11.

[0049] In one embodiment, a second card slot 324 is further provided on the side wall of the receiving hole 321. The second card slot 324 communicates with one end of the first chute 322 away from the first end portion. The second card slot 324 and the first card slot 323 are located on the same side of the first chute 322. When the locking post 3321 is placed in the second chute 3311, the control rod 33 locks the locking bolt 32 and retracts it to a position within the support cylinder 31.

[0050] Under normal circumstances, when the washing machine is in a non-transport state, it is desired that the locking pin 32 can be fully retracted into the support cylinder 31 to avoid unnecessary collisions or interferences with the washing cylinder 1 or other components. By placing the latch post 3321 in the second card slot 324 and maintaining it with the torsion of the torsion spring 37, it can be ensured that the locking pin 32 will not accidentally protrude from the support cylinder 31 without being manually operated.

[0051] In one embodiment, an inner retaining ring 312 is provided at the second end of the support cylinder 31. One end of the locking pin 32 close to the first end is connected with an outer retaining ring 325. The inner retaining ring 312 can limit the outer retaining ring 325 within the support cylinder 31 to limit the locking pin 32 from completely disengaging from the support cylinder 31.

[0052] When the user pushes out the locking pin 32 through the control rod 33, due to the presence of the inner retaining ring 312 and the outer retaining ring 325, the locking pin 32 will not accidentally fall off from the support cylinder 31, thus avoiding the problem that the locking pin 32 is difficult to reinstall after falling off.

[0053] In one embodiment, a rib 326 is provided on the side wall of the outer retaining ring 325. An axially extending anti-rotation groove 313 adapted to the rib 326 is provided on the inner wall of the support cylinder 31. The rib 326 is snapped into the anti-rotation groove 313 to limit the rotation of the locking pin 32.

[0054] The design of the anti-rotation structure avoids the uncontrolled rotation of the locking pin 32, thus ensuring that the latch post 3321 can accurately cooperate with the first card slot 323 or the second card slot 324 to achieve the locking or unlocking function.

[0055] In one embodiment, an outwardly protruding first shoulder 311 is provided at the first end of the support cylinder 31. A threaded portion is provided on the outer wall of the support cylinder 31 near the first shoulder 311. A fixing nut 34 is installed on the threaded portion. The support cylinder 31 is fixed to the frame 2 by the clamping of the fixing nut 34 and the first shoulder 311.

[0056] Through the combined action of the threaded connection and the clamping force, the stability of the support cylinder 31 on the frame 2 can be ensured. Even when the washing machine encounters vibrations or impacts during operation, the support cylinder 31 is not likely to loosen or fall off.

[0057] In one embodiment, refer to Figure 6, further comprising a locking member 35, the locking member 35 including a connected nut portion 352 and a limit ring portion 351; the control lever 33 has spaced second shoulder 3312 and third shoulder 3313 at its operating end, and the limit ring portion 351 is restricted between the second shoulder 3312 and the third shoulder 3313; the first shoulder 311 has an external thread, and the nut portion 352 is threadedly connected to the first shoulder 311 to lock the control lever 33 to the support cylinder 31.

[0058] At the operating end of the control lever 33, a spaced second shoulder 3312 and third shoulder 3313 are provided, and the space between them is used to accommodate the limit ring portion 351. When the locking member 35 is installed on the control lever 33, the limit ring portion 351 will be restricted between the second shoulder 3312 and the third shoulder 3313, preventing it from moving axially along the control lever 33. The first shoulder 311 of the support cylinder 31 is provided with an external thread, and the nut portion 352 of the locking member 35 is matched with the external thread for threaded connection. By rotating the locking member 35, the nut portion 352 is tightly threadedly connected to the first shoulder 311, thereby firmly locking the control lever 33 to the support cylinder 31. This locking method is not only simple and reliable but also can effectively prevent the control lever 33 from accidentally moving or falling off during the operation of the washing machine.

[0059] In one embodiment, a handle 36 is connected to the operating end of the control lever 33.

[0060] Through the handle 36, the user can more conveniently rotate and push and pull the control lever 33 to realize the extension and retraction operations of the locking bolt 32.

[0061] On the other hand, a washing machine is provided, including the above-mentioned laundry tub transportation and fixing structure.

[0062] Similarly, based on the laundry tub transportation and fixing structure of this embodiment, before transportation, the laundry tub 1 of this embodiment of the washing machine can be locked by the fixing component 3 to provide protection. When installing the washing machine, the fixing component 3 can be directly unlocked. Since the fixing component 3 in this solution is directly fixed in the frame 2, it still remains stationary inside the washing machine after unlocking, and the user does not need to consider the problem of having to separately store it after removal. Therefore, when the washing machine still needs to be moved after use, the fixing component 3 is released again to lock the laundry tub 1, and the laundry tub 1 can be protected.
