Abstract
Description
Technical Field
[0001] This utility model relates to the field of cleaning tool technology, specifically to a drain rack. Background Technology
[0002] Drain racks are common tools in kitchens and bathrooms, providing drying and drainage for cleaning tools or tableware, and are gradually becoming an essential tool in people's daily lives.
[0003] Currently, existing rotating drain racks are typically used in two fixed states: horizontal and vertical. However, when there are obstacles in the placement of the rack in one state, such as other items on the wall where it is installed, preventing the drain rack from rotating to the vertical state, it needs to be moved to a different location. Since drain racks are usually part of other larger cleaning devices, the obstacles themselves and the narrow kitchen and bathroom spaces may also pose inconvenience for relocation. Utility Model Content
[0004] In view of this, the present invention provides a drain rack to solve the problem that the existing drain racks are difficult to avoid obstacles and cannot be fixedly installed to achieve their functions.
[0005] In a first aspect, this utility model provides a drain rack for support on a support platform. The support platform has a water tank and includes a base, a frame, and a locking assembly. The base is mounted on the support platform. The frame is rotatably connected to the base so that the frame has a first support position and a flipped-up position. When the frame is in the first support position, the free end of the frame is close to the water tank. When the frame is in the flipped-up position, the free end of the frame is away from the water tank and located above the base. The frame also has at least one second support position located between the first support position and the flipped-up position. When the frame is in the second support position, at least a portion of the frame is located above the water tank. The locking assembly is disposed between the base and the frame and is used to limit the frame in the second support position.
[0006] Beneficial effects
[0007] By setting the frame and base to be rotatably connected, and having a first support position, a flip-up position, and at least one second support position between the two positions, and by setting a locking component to limit the frame to the second support position, this configuration, through the change of rotation angle and the limitation of the locking component, can add more positions between the two limited positions of the frame to stabilize the load on other structures. This allows the frame to move away from obstacles that may exist at the first support position or the flip-up position, expanding the applicability of the frame and effectively overcoming the problem in the prior art that the drain rack is difficult to avoid obstacles and cannot be fixedly installed to achieve its own function.
[0008] Furthermore, while existing drain racks can be used to dry rags and other items when vertical, water from the rags drips onto the base. If the drain rack is used horizontally, it covers the sink, rendering it unusable. In contrast, the drain rack in the second support position has part of its frame above the sink, allowing water from the rags on the rack to drip directly into the sink; and it doesn't completely cover the sink, leaving part of the sink still usable.
[0009] In one optional embodiment, the rotation direction of the free end of the frame from the flipped-up position to the first support position is a first direction; the rotation direction of the free end of the frame from the first support position to the flipped-up position is a second direction.
[0010] In one alternative implementation, when the frame is in the second supported position, the locking component restricts the frame from rotating relative to the base in the first direction, but does not restrict the frame from rotating relative to the base in the second direction.
[0011] Beneficial effects
[0012] When the support platform is in a conventional horizontal position, rotation in the first direction is a flip from vertical to horizontal, and rotation in the second direction is a flip from horizontal to vertical. Therefore, when the frame is in the second support position, it is subjected to downward gravity and load in the connection direction. The locking component only needs to restrict its rotation relative to the first direction to stabilize and limit the movement of the frame, meet the load requirements, and reduce the structural complexity and cost of the locking component.
[0013] In one optional embodiment, the locking assembly includes a first locking member, a second locking member, and a switch member: one of the first locking member and the second locking member is disposed on the frame, and the other is disposed on the base; the first locking member and the second locking member have a limited state and an unlocked state; when in the limited state, the first locking member and the second locking member cooperate to restrict the frame located at the second support position from rotating relative to the base in the first direction; when in the unlocked state, the first locking member and the second locking member separate, releasing the limitation on the frame; the switch member is connected to the first locking member and is used to drive the first locking member to move, so as to drive the first locking member and the second locking member to switch from the limited state to the unlocked state.
[0014] In one optional embodiment, the second locking member includes a one-way limiting body, on which a limiting portion is provided corresponding to the second support position; the first locking member includes a snap-fit component, which protrudes toward the one-way limiting body, engages with the limiting portion along the first direction, and is adapted to move away from the one-way limiting body under the action of the switching member, and disengage from the snap-fit connection with the limiting portion.
[0015] Beneficial effects
[0016] Compared to other reusable limiting methods such as screwing, bonding, and magnetic attraction, the snap-fit limiting method has a more stable structure that can withstand a larger load during limiting. At the same time, under the action of switching components and external forces, the speed of disengaging from the limiting position is relatively fast, effectively meeting the load and angle adjustment needs of the drain rack.
[0017] In one optional implementation, the unidirectional limiting body is a ratchet.
[0018] Beneficial effects
[0019] The unidirectional limiting body is set as a ratchet, and the limiting part on it corresponds to the ratchet teeth. It not only has a preset bias to meet the limiting requirement for a fixed rotation direction, but also the teeth can be distributed along the circumferential part of the wheel body or at a corresponding angle as needed to meet the user's structural needs for multiple second support positions.
[0020] In one alternative embodiment, the unidirectional limiting body is disposed on the base, and the snap-fit assembly is disposed on the frame.
[0021] Beneficial effects
[0022] With this configuration, the unidirectional limiting body remains stationary during the movement of the frame relative to the base. On the one hand, this facilitates the design and calculation of the number and specific position of the upper limit part of the unidirectional limiting body according to load and angle requirements. On the other hand, when the unidirectional limiting body is a ratchet, there is no need for the ratchet to move, reducing the possibility of jamming with foreign objects or scratching other structures.
[0023] In one optional embodiment, the snap-fit assembly includes: an elastic member, one end of which is connected to the base and the other end of which extends toward the unidirectional limiting body; and a snap-fit member, which is connected to the elastic member, or connected to both the elastic member and the base, wherein the snap-fit member is adapted to engage with the limiting portion under the action of the elastic member, or to move away from the limiting portion and disengage under the drive of the switching member.
[0024] Beneficial effects
[0025] The elastic element allows the snap-fit component to remain in a contacting and engaging state with the limiting part, while also providing a certain buffering effect to prevent hard contact between the snap-fit component and the limiting part, thereby reducing structural damage to the internal parts of the snap-fit assembly when the drain rack is subjected to external forces.
[0026] In one alternative embodiment, one end of the switch is connected to the snap-fit element, and the other end is provided with a handle.
[0027] In one alternative embodiment, the frame includes a hollow frame, one end of which is rotatably connected to the base.
[0028] In one optional embodiment, the frame further includes a plurality of support rods located inside the frame; and / or, the frame further includes a plurality of legs protruding from the frame and adapted to contact the support platform at the first support position to support the frame.
[0029] In one optional embodiment, the frame further includes: a connector, one end of which is limitedly connected to the frame and the other end of which is hinged to the base; at least one of the connectors is provided with a receiving groove, adapted to correspondingly connect and receive a snap-fit assembly, and one end of the switch passes through the connector and is connected to the snap-fit assembly.
[0030] Beneficial effects
[0031] By adding additional connectors, there is no need to set up receiving slots for the snap-fit components on the frame, avoiding structural modifications to the standard frame and reducing structural costs.
[0032] In one optional embodiment, the connector and the base are arranged in pairs, with the connector correspondingly connected to adjacent corner positions of the frame; the support leg is correspondingly arranged on the corner position of the frame away from the base.
[0033] Beneficial effects
[0034] By setting up a combination structure of connectors and bases, with the legs placed on opposite corners of the frame, and the connectors and bases being set in pairs, the load-bearing structure of the frame is at least triangularly distributed. Depending on the number of legs, it can also be distributed in other polygonal ways, effectively stabilizing the frame and ensuring the normal operation of the drain rack.
[0035] In one optional embodiment, the base includes: a main seat with a built-in seat cavity, the seat cavity being hinged to the frame and accommodating a one-way limiting body.
[0036] Beneficial effects
[0037] The seat cavity serves two purposes: firstly, it can accommodate the unidirectional limiting body, protect and isolate it, and prevent damage to its own structure and external scratches; secondly, it can be configured with its own inner wall to limit the travel of the frame, meeting the limiting requirements of the frame in the first support position and the flipped-up position.
[0038] In one optional embodiment, the base further includes: a guide plate disposed within the seat cavity, including a first limiting part; a second limiting part disposed on the guide plate and movablely limiting the first limiting part; a first limiting mating part disposed on the side of the unidirectional limiting body and engaging with the first limiting part for limiting; and a second limiting mating part disposed on the seat cavity and cooperating with the second limiting part for limiting.
[0039] Beneficial effects
[0040] The cooperation and limiting of the second limiting part with the second limiting mating part, and the engagement and limiting of the first limiting part with the first limiting mating part, ensure that the guide plate is limited within the seat cavity. Simultaneously, the guide plate helps to limit and fix the unidirectional limiting main body within the seat cavity, fulfilling the positioning requirements of the unidirectional limiting main body and preventing angular deviations during installation. Furthermore, the movable limiting of the second limiting part and the first limiting part allows the second limiting part to be non-integrated with the guide plate, facilitating the design and manufacturing of the guide plate and reducing structural costs.
[0041] In one optional embodiment, the first limiting part is a card hole, and the first limiting mating part is a protrusion; and / or, the second limiting part is a stepped card block, and the second limiting mating part is a card groove.
[0042] In one optional embodiment, the drain rack further includes: a guide arc hole disposed on the guide plate, with the hinge axis between the seat cavity and the frame body as the central axis; and a guide post disposed on the connector and passing through the guide arc hole, the distance between the guide post and the hinge axis being equal to the radius of the guide arc hole.
[0043] Beneficial effects
[0044] Guide arc holes are set on the guide plate to cooperate with the guide columns. The guide arc holes serve as the movement trajectory of the guide columns, which can correct small deviations in the rotational movement of the frame. At the same time, the two ends of the guide arc holes are the travel limits of the guide columns, corresponding to the first support position and the flipping position of the frame, to prevent the frame movement from exceeding the preset position.
[0045] In one alternative embodiment, the frame has a plurality of second support positions, which are spaced apart along the rotation direction of the frame.
[0046] Beneficial effects
[0047] The frame has multiple secondary support positions, which can meet the drainage needs at different angles and the need to avoid obstacles of different sizes and positions.
[0048] In one alternative embodiment, the drain rack further includes a suction cup structure connected to the bottom of the base and adapted to adhere to the support platform.
[0049] Beneficial effects
[0050] By setting up a suction cup structure, the base can be attached to the support platform, which increases the overall structural stability of the drain rack, improves its load-bearing capacity, and prevents the drain rack from tipping over under external forces. Attached Figure Description

[0060] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0061] The following is combined Figures 1 to 6 The following describes embodiments of the present invention.
[0062] In the first aspect, this utility model provides a drain rack for support on a support platform, the support platform having a water tank, and the drain rack including a base 2, a frame 1, and a locking component 3.
[0063] The base 2 is mounted on a support platform, which is usually horizontal, but can also be tilted as needed. In this embodiment, a horizontal setting is used as an example.
[0064] The frame 1 is rotatably connected to the base 2, preferably by a hinged connection, so that the frame 1 has a first support position and a flip-up position. Preferably, the first support position and the flip-up position are horizontal and vertical positions, respectively, in this embodiment. They can also be adjusted to other positions and angles that meet the drainage requirements as needed.
[0065] The frame 1 has a hinged end connected to the base 2 and a free end away from the base 2. When the frame 1 is in the first supported position, the free end of the frame 1 is close to the water tank on the support platform. When the frame 1 is in the flipped-up position, the free end of the frame 1 is away from the water tank and is located above the base 2, while its hinged end remains hinged to the base 2.
[0066] The frame 1 also has a second support position located between the first support position and the flipped-up position. When the frame 1 is in the second support position, at least part of the frame 1 is above the water tank. The locking component 3 is located between the base 2 and the frame 1 to limit the frame 1 to the second support position. The second support position can be set as one, two, or more, and the number and spacing angle of its distribution can be adjusted as needed.
[0067] By setting the frame 1 to be rotatably connected to the base 2, and having a first support position, a flip-up position, and at least one second support position between the two positions, and setting a locking component 3 to limit the frame 1 to the second support position, this setting allows for the addition of more positions between the two limited positions of the frame 1 to stabilize the load on other structures. This enables the frame 1 to move away from obstacles that may exist at the first support position or the flip-up position, expanding the applicability of the frame 1 and effectively overcoming the problem in the prior art that the drain rack is difficult to avoid obstacles and cannot be fixedly installed to achieve its function.
[0068] Furthermore, in the existing technology, the drain rack can be used to dry rags and other items when vertical. However, water from the rags will drip onto the base 2. If the rags are dried horizontally, the drain rack will cover the sink, rendering it unusable. In contrast, with the drain rack at the second support position, part of the frame 1 is positioned above the sink, allowing water from the rags on the rack to drip directly into the sink; and it does not completely cover the sink, leaving part of the sink still usable.
[0069] Since the installation position and orientation of the drain rack may vary, it is necessary to avoid defining its rotation direction using clockwise or counterclockwise. In this embodiment, the rotation direction of the free end of the rack 1 when switching from the flipped-up position to the first support position is defined as the first direction; the rotation direction of the free end of the rack 1 when switching from the first support position to the flipped-up position is defined as the second direction. Understandably, the first and second directions can also be set in opposite directions.
[0070] In this embodiment, when the frame 1 is in the second support position, the locking component 3 restricts the frame 1 from rotating relative to the base 2 in the first direction, but does not restrict the frame 1 from rotating relative to the base 2 in the second direction. That is, the frame 1 is unidirectionally limited.
[0071] When the support platform is in a conventional horizontal position, rotation in the first direction is a flip from vertical to horizontal, and rotation in the second direction is a flip from horizontal to vertical. Therefore, when the frame 1 is in the second support position, it is subjected to downward gravity and load in the connecting direction. The locking component 3 only needs to restrict its rotation relative to the first direction to stably limit the movement of the frame 1, meet the load requirements, and reduce the structural complexity and cost of the locking component 3. Moreover, it does not restrict the rotation of the frame 1 in the second direction. Based on this, when it is necessary to rotate the frame 1 to the flipped position, it can be directly rotated without unlocking. Therefore, the drain rack provided by this utility model is more convenient and faster to use.
[0072] As an alternative implementation, when the frame 1 is in the second support position, a locking component 3 can be set to limit the bidirectional movement of the frame 1 along the first and second directions. Specifically, when bidirectionally limited, the frame 1 and the base 2 can be limited by a locking block and a locking groove in the second support position. Alternatively, limiting holes and limiting components, such as bolts, can be set at the locations of the frame 1 and the base 2 corresponding to the second support positions to limit the frame 1 and the base 2.
[0073] Meanwhile, the frame 1 has a first support position, a second support position, and a tilted position, and different positions can be selected according to different objects to be drained. The first support position can be horizontal, and the second support position can be tilted upwards. In this case, spherical objects that are easy to roll can be drained at the first support position, and rags and the like can be drained at the second support position.
[0074] In addition, the first support position can be limited by the locking component, or it can be limited after contacting the surface of the support platform. The flipped position can be limited by the locking component, or it can be limited by the structure such as the wall. Furthermore, it can also be limited by its own angle and gravity after the transition flip.
[0075] In this embodiment, the locking component 3 includes a first locking element, a second locking element, and a switch element 34.
[0076] One of the first locking member and the second locking member is located on the frame 1, and the other is located on the base 2. In this embodiment, the first locking member is located on the frame 1, and the second locking member is located on the base 2.
[0077] The first locking member and the second locking member have a limited state and an unlocked state. When in the limited state, the first locking member and the second locking member cooperate to restrict the frame 1 located at the second support position from rotating relative to the base 2 in the first direction; when in the unlocked state, the first locking member and the second locking member separate, releasing the limitation on the frame 1; the switch member 34 is connected to the first locking member and is used to drive the first locking member to move, so as to drive the first locking member and the second locking member to switch from the limited state to the unlocked state.
[0078] The user can drive the first locking element through the switch element 34, thereby conveniently controlling the locking or unlocking of the first and second locking elements.
[0079] In this embodiment, the first locking member and the second locking member are set relatively independently. As an alternative implementation, the first locking member and the second locking member can also be part of the frame 1 or the base 2.
[0080] Specifically, the second locking element includes a one-way limiting body 31, and a limiting part is provided on the one-way limiting body 31 corresponding to the second support position. The number of limiting parts can be one, two or more, corresponding to the number of the second support positions.
[0081] The first locking element includes a snap-fit assembly that protrudes towards the unidirectional limiting body 31, engages with the limiting portion along a first direction, and is adapted to move away from the unidirectional limiting body 31 and disengage from the limiting portion under the action of the switching element 34. As a variable implementation, the limiting method between the snap-fit assembly and the limiting portion can also be other reusable limiting methods such as screwing, bonding, or magnetic attraction.
[0082] Compared to other reusable limiting methods such as screwing, bonding, and magnetic attraction, the snap-fit limiting method has a more stable structure and can withstand a larger load during limiting. At the same time, under the action of the switch 34 and external force, the speed of disengaging from the limiting is relatively fast, effectively meeting the load and angle adjustment needs of the drain rack.
[0083] Preferably, the one-way limiting body 31 is a ratchet. The one-way limiting body 31 is a ratchet, with the limiting portion corresponding to the ratchet teeth. It not only has a preset bias to meet the limiting requirement for a fixed rotation direction, but also the teeth can be distributed along the circumferentially close portion of the wheel body or at a corresponding angle as needed, meeting the user's structural requirements for multiple second support positions.
[0084] As a possible implementation method, the unidirectional limiting body 31 can also be a ring magnet, a ring hook and loop fastener, a ring-shaped part with multiple threaded holes or studs, etc.
[0085] In this embodiment, the one-way limiting body 31 is disposed on the base 2, and the snap-fit assembly is disposed on the frame 1. This arrangement ensures that the one-way limiting body 31 remains stationary during the movement of the frame 1 relative to the base 2. On the one hand, this facilitates the design and calculation of the number and specific position of the upper limiting parts of the one-way limiting body 31 according to load and angle requirements. On the other hand, when the one-way limiting body 31 is a ratchet, there is no need for ratchet movement, reducing the possibility of jamming with foreign objects or scratching other structures.
[0086] Understandably, when the first locking element is moved to the base 2 and the second locking element is moved to the frame 1, the installation positions of the one-way limiting body 31 and the snap-fit assembly are also changed accordingly.
[0087] The snap-fit assembly includes: an elastic element 32 and a snap-fit element 33.
[0088] The elastic element 32 is specifically a spring, or it can be an elastic structure such as a rubber body or a silicone body. One end of it is connected to the base 2, and the other end extends toward the one-way limiting body 31. The base 2 is provided with a column structure that limits the connection of the elastic element 32.
[0089] In this embodiment, the snap-fit member 33 is connected to both the elastic member 32 and the base 2, and is hinged to the base 2. Specifically, the hinge point can be the guide post 141. The snap-fit member 33 and the elastic member 32 are snap-fitted or bonded together. This connection configuration improves the movement stability of the snap-fit member 33. The snap-fit member 33 is suitable for engaging with the limiting part under the action of the elastic member 32, or for moving away from the limiting part and disengaging under the drive of the switch member 34. As an alternative implementation, the snap-fit member 33 may be connected only to the elastic member 32.
[0090] The elastic element 32 allows the snap-fit element 33 to remain in abutting and engaged position with the limiting part, while also providing a certain buffering effect to prevent hard contact between the snap-fit element 33 and the limiting part, thereby reducing structural damage to the internal parts of the snap-fit assembly when the drain rack is subjected to external force.
[0091] Preferably, one end of the switch 34 is hook-shaped and connected to the snap-fit member 33. Preferably, the snap-fit member 33 is located near the end of the elastic member 32. The other end of the switch 34 is provided with a handle 35, which is exposed to facilitate the user's pulling and releasing operation.
[0092] The frame 1 includes a hollow frame 11. The frame 11 can be triangular, rectangular, circular, or polygonal. In this embodiment, it is a rectangular frame. One end of the frame 11 is rotatably connected to the base 2. The frame 1 can be configured into other shapes as needed, such as a perforated plate.
[0093] The frame 1 also includes a plurality of support rods 12 located inside the frame 11, which can be arranged in parallel or intersecting positions. The frame 1 also includes a plurality of legs 13 protruding from the frame 11 and adapted to contact the support platform at a first support position to support the frame 1. The number of legs 13 can be single, two, or multiple. As an alternative implementation, only one of the support rods 12 and legs 13 may be provided.
[0094] The frame 1 also includes connector 14.
[0095] One end of the connector 14 is limited and connected to the frame 11, which can be a snap-fit or threaded connection, preferably a detachable connection. The other end of the connector 14 is hinged to the base 2. The number of connectors 14 is less than or equal to the number of bases 2. In this embodiment, two connectors are provided. One of the connectors 14 is provided with a receiving slot 15, which is suitable for corresponding connection and accommodating the snap-fit component. One end of the switch 34 passes through the connector 14 and is connected to the snap-fit component 33. By providing additional connectors 14, it is not necessary to provide receiving slots 15 for snap-fit components on the frame 11, avoiding structural modifications to the standard frame and reducing structural costs. As an alternative implementation, one or more connectors 14 can be provided.
[0096] In this embodiment, the connector 14 and the base 2 are arranged in pairs, with the connector 14 connected to the adjacent corner of the frame 11; the support leg 13 is arranged on the corner of the frame 11 away from the base 2. In this embodiment, there are two support legs 13, corresponding to the rectangular frame 11. When the frame 11 is a triangular frame, only one support leg 13 may be provided.
[0097] By setting up a combined structure of connector 14 and base 2, which are placed on opposite corners of frame 11 along with support legs 13, and when connector 14 and base 2 are set in pairs, the load-bearing structure of frame 1 is at least triangularly distributed. Depending on the number of support legs 13, it can also be distributed in other polygonal ways, which effectively stabilizes and supports frame 1 and ensures the normal operation of the drain rack.
[0098] Specifically, the base 2 includes a main seat 21, which has a built-in seat cavity 22. The seat cavity 22 is hinged to the frame 1 and accommodates a one-way limiting body 31. The seat cavity 22 serves two purposes: firstly, it can accommodate the one-way limiting body 31, protecting and isolating it from structural damage and external scratches; secondly, its inner wall can be configured as needed to limit the travel of the frame 1, satisfying the limiting requirements of the frame 1 in the first support position and the flipped-up position.
[0099] As an alternative implementation, the seat cavity 22 may be omitted, and the one-way limiting body 31 may be placed outside the main seat 21, with a protective shell covering its outer side.
[0100] The base 2 also includes a guide plate 23, which is disposed within the seat cavity 22 and includes a first limiting part 231. A second limiting part 24 is disposed on the guide plate 23 and is movablely limited with the first limiting part 231. A first limiting mating part 311 is disposed on the side of the unidirectional limiting body 31 and engages with the first limiting part 231 for limitation. A second limiting mating part 221 is disposed on the seat cavity 22 and cooperates with the second limiting part 24 for limitation.
[0101] The engagement of the second limiting part 24 with the second limiting mating part 221, and the locking of the first limiting part 231 with the first limiting mating part 311, limit the guide plate 23 within the seat cavity 22. Simultaneously, the guide plate 23 helps to fix the unidirectional limiting body 31 within the seat cavity 22, fulfilling the positioning requirements of the unidirectional limiting body 31 and preventing angular deviations during installation. Furthermore, the movable limiting of the second limiting part 24 and the first limiting part 231 allows the second limiting part 24 to be non-integrated with the guide plate 23, facilitating the design and fabrication of the guide plate 23 and reducing structural costs.
[0102] As an alternative implementation, the second limiting part 24 and the guide plate 23 can be integrally provided. As another alternative implementation, the guide plate 23 can be omitted, and the one-way limiting body 31 can be directly limited and connected to the seat cavity 22.
[0103] Specifically, the first limiting part 231 is a locking hole, and the first limiting mating part 311 is a protrusion; the second limiting part 24 is a stepped locking block, and the second limiting mating part 221 is a locking groove. Understandably, only one of the two sets of limiting parts can be provided.
[0104] The drain rack also includes a guide arc hole 232 and a guide post 141. The guide arc hole 232 is disposed on the guide plate 23, with the hinge axis between the seat cavity 22 and the frame 1 as the central axis. In this embodiment, the corresponding angle is 90 degrees. The guide post 141 is disposed on the connector 14 and passes through the guide arc hole 232. The distance between the guide post 141 and the hinge axis is equal to the radius of the guide arc hole 232.
[0105] A guide arc hole 232 is provided on the guide plate 23 to cooperate with the guide column 141. The guide arc hole 232 serves as the movement trajectory of the guide column 141, which can correct the slight deviation of the rotational movement of the frame 1. At the same time, the two ends of the guide arc hole 232 are the travel limits of the guide column 141, corresponding to the first support position and the flipping position of the frame 1, to prevent the frame 1 from moving beyond the preset position.
[0106] The frame 1 has multiple second support positions, which are spaced apart along the rotation direction of the frame 1. In this embodiment, they correspond to multiple teeth of a ratchet. Having multiple second support positions on the frame 1 can meet the drainage needs at different angles and the need to avoid obstacles of different sizes and positions. As a variable implementation, only one or two second support positions may be provided.
[0107] In this embodiment, the drain rack also includes a suction cup structure 25, which is connected to the bottom of the base 2 and is suitable for adhering to the support platform. By setting the suction cup structure 25, the base 2 can be adhering to the support platform, increasing the support stability of the overall structure of the drain rack, improving the load-bearing capacity, and preventing the drain rack from tipping over under external forces.
[0108] Work process:
[0109] The base 2 of the drain rack is attached to the support platform by the suction cup structure 25, so that when the rack 1 is in the first support position, its lower side is a water tank.
[0110] The frame 1 is pushed to rotate relative to the base 2 to the second support position corresponding to the required angle. During the process, the first locking member moves with the frame 1, and the locking member 33 rotates relative to the one-way limiting body 31. When it stops at the second support position, the locking member 33 is locked onto the limiting part, and the frame 1 cannot rotate to the first support position and stays at the second support position. The frame 1 avoids the obstacle.
[0111] When it is necessary for frame 1 to move toward the flipped-up position, simply push frame 1 to continue rotating in the second direction;
[0112] When the frame 1 needs to fall back to the first support position or another second support position close to the first support position, pull the handle 35, pull the locking member 33 to compress the elastic member 32, so that the locking member 33 is disengaged from the limiting part of the one-way limiting body 31, push the frame 1 to rotate relative to the base 2 to the first support position or another second support position close to the first support position, and release the handle 35.
[0113] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
