Description

Technical Field

[0001] This utility model relates to the field of support frame technology, and more specifically to a folding support frame. Background Technology

[0002] In recent years, flexible pool structures (such as bathtubs made of waterproof fabric, air conditioner cleaning covers, and portable water tanks) have been widely used in home, industrial, and outdoor settings due to their lightweight, portability, and rapid deployment. These flexible pools typically require rigid or semi-rigid support structures (i.e., keel support frames) to maintain their shape and prevent collapse or deformation caused by uneven internal pressure or external forces.

[0003] However, in existing technologies, the support frames for flexible pools mostly adopt an integrated fixed frame structure, using metal or plastic support frames to constrain the side walls of the pool. While this design provides stable mechanical support, it has significant drawbacks: the integral support frame prevents the flexible pool from folding, occupies a large space when not in use, and results in high transportation and storage costs; some support frames use a detachable connection to the flexible pool, but this requires additional disassembly and assembly steps, making operation cumbersome. Utility Model Content

[0004] To solve the above problems, this utility model provides the following technical solution:

[0005] A folding support frame includes several keel plates connected sequentially by hinges. The hinges are either damping hinges or positioning components are provided at the hinge points of the keel plates. The several keel plates include a main keel plate, and secondary keel plates are respectively hinged to the left and right ends of the main keel plate. The height of the secondary keel plate facing the main keel plate is lower than the height of the main keel plate.

[0006] The present invention is further configured such that: the damping hinge is a damping hinge, and the two sides of the damping hinge are respectively fixed to two adjacent keel plates; the damping hinge restricts the rotation angle through the frictional force of interference fit or a damper.

[0007] The present invention is further configured such that: the positioning component includes an L-shaped pin movably disposed on the main keel plate, and a slot opened on the secondary keel plate, wherein the L-shaped pin passes into the slot to limit the rotation angle of the secondary keel plate.

[0008] The present invention is further configured such that: a connector is provided on the support frame, the connector being used to hang the support frame.

[0009] The present invention is further configured such that: the keel plate is rectangular, the length of the main keel plate is greater than or equal to the length of the secondary keel plate, and several keel plates are connected to form a semi-closed structure.

[0010] The present invention is further configured such that: the top of both the left and right ends of the main keel plate is provided with a first rounded corner, and the top of the end of the secondary keel plate away from the main keel plate is provided with a second rounded corner.

[0011] The present invention is further configured such that: a reinforcing rib is provided on the main keel plate, and the reinforcing rib is formed by bending the main keel plate itself.

[0012] The present invention is further configured such that: the top of the secondary keel plate has a bent portion, the bent portion is horizontally arranged and perpendicular to the secondary keel plate, and the bent portion is bent inward.

[0013] The present invention is further configured such that: the connecting member is a hanging rope, and the two ends of the hanging rope are respectively fixed to the side walls of the two keel plates.

[0014] The present invention is further configured such that at least one of the secondary keel plates is hinged to a third keel plate at one end away from the main keel plate.

[0015] Compared with the prior art, the present invention has at least the following advantages:

[0016] 1. It includes several keel plates that can be fixed to the side wall of the flexible pool using fasteners. The keel plates are connected by damping hinges, which prevents the keel plates from rotating easily. This provides a stable polygonal support structure for the flexible pool. When storage is required, external force can be applied to make the keel plates drive the flexible pool to fold and store, which significantly reduces storage and transportation costs and is very convenient and quick to operate.

[0017] 2. Set the height of the secondary keel plate facing the main keel plate to be lower than the height of the main keel plate. This makes the support frame more suitable for air conditioner cleaning covers. The main keel plate can be inserted into the back of the air conditioner to act as a wall covering, preventing the wastewater generated during air conditioner cleaning from flowing down the wall. At this time, the secondary keel plate will not interfere with the copper pipes on the air conditioner, making it more suitable for air conditioner cleaning scenarios. By setting connectors, when the support frame is used for air conditioner cleaning covers, the support frame can be directly hung on the air conditioner through the connectors.

[0018] 3. By creating rounded corners at both ends of the main keel plate and the end of the secondary keel plate, the product not only looks more aesthetically pleasing, but also makes it less likely for users to be injured during use, thus improving safety. Attached Figure Description

[0025] 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. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0026] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] A folding support frame, such as Figures 1 to 3 As shown, the system includes several keel plates, which are connected sequentially by hinges. These hinges can be damping hinges or have positioning components at their hinge points. The rotation angle of the keel plates can be fixed directly through the damping hinges, or fixed by additional positioning components. The keel plates include a main keel plate 1, with secondary keel plates 2 hinged to its left and right ends. In this embodiment, three keel plates are specifically provided: one main keel plate 1 and two secondary keel plates 2. The main keel plate 1 and the secondary keel plates 2 form a semi-enclosed structure. The keel plates are not connected end-to-end to form a fully enclosed structure, allowing the support frame to be folded and retracted.

[0028] The support frame can be used to connect with the flexible pool body 9 formed by the waterproof fabric. The keel plates are fixed to the side walls of the flexible pool body 9, providing a stable support structure for the flexible pool body 9. Since the keel plates are hinged with damping hinges 3, they will not easily rotate during use, meeting the support strength requirements. The user can also fold the keel plates by applying external force.

[0029] The keel plate can be fixed to the flexible pool body 9 using fasteners. For example, bolts can be threaded onto the keel plate and passed through the side wall of the flexible pool body 9, with nuts attached to the bolts for fixation. Alternatively, rivets can be used, or glue can be applied directly for fixation. The support frame only needs to be fixed to the flexible pool body 9 once and will not be removed afterward.

[0030] The keel plate is rectangular. The length of the main keel plate 1 is greater than or equal to the length of the secondary keel plate 2. In this embodiment, both the main keel plate 1 and the secondary keel plate 2 are rectangular, and the length of the main keel plate 1 is greater than the length of the secondary keel plate 2.

[0031] In this embodiment, the hinge is a damping hinge, specifically a damping hinge 3. One side of the damping hinge 3 is fixed to the main keel plate 1 with screws, and the other side is fixed to the secondary keel plate 2 with screws, allowing one end of the secondary keel plate 2 to rotate around the main keel plate 1. Both secondary keel plates 2 rotate on the same side of the main keel plate 1. The damping hinge 3 limits the rotation angle through interference fit friction or a damper, so that the keel plates can be positioned at the current angle when no force is applied by the user, and can rotate directly when the user applies a larger force. Rotating the two secondary keel plates 2 towards the middle allows the support frame to be folded into a straight line for storage. Rotating the two keel plates outwards until they are perpendicular to the main keel plate 1 forms a U-shaped structure for the support frame, providing support for the square flexible pool body 9.

[0032] In other embodiments, a positioning component (not shown in the figure) can be additionally provided at the hinge of the keel plate to fix the rotation angle of the keel plate. The positioning component includes L-shaped pins movably disposed at the left and right ends of the main keel plate 1, and slots formed in the secondary keel plate. When the secondary keel plate 2 rotates to be perpendicular to the main keel plate 1, the L-shaped pins pass into the slots, thereby limiting the rotation angle of the secondary keel plate. The L-shaped pins are connected to the main keel plate 1 by two rings, allowing the L-shaped pins to move in both the horizontal and vertical directions. This positioning component can refer to the positioning method of existing windows.

[0033] The secondary keel plate 2 is lower in height than the main keel plate 1 at the end facing it. Specifically, the secondary keel plate 2 can be configured to have an overall height lower than the main keel plate 1, or it can be configured to have a downwardly recessed notch at the end facing the main keel plate 1. In this embodiment, the secondary keel plate 2 is lower in overall height than the main keel plate 1. When the support frame is used to fix it on the air conditioner cleaning cover, the main keel plate 1 can be inserted into the back of the air conditioner to act as a wall cover, preventing the wastewater generated during air conditioner cleaning from flowing down the wall. At this time, because the secondary keel plate 2 is lower in height, the secondary keel plates 2 on both sides will not interfere with the copper pipes on the air conditioner, making it more suitable for air conditioner cleaning scenarios.

[0034] In other embodiments, at least one of the secondary keel plates 2 is hinged to a third keel plate (not shown in the figure) at the end away from the main keel plate 1, so that the support frame can be adapted to the pentagonal flexible pool body 9. Similarly, when used for the hexagonal flexible pool body 9, an additional third keel plate is added, and so on.

[0035] In this embodiment, the top of both ends of the main keel plate 1 is provided with a first rounded corner 4, and the top of the end of the secondary keel plate 2 away from the main keel plate 1 is provided with a second rounded corner 5. The rounded corners not only make the product more rounded and beautiful, but also prevent users from puncturing the ends during use, thus improving safety performance.

[0036] The main keel plate 1 is provided with reinforcing ribs 6, which in this embodiment are formed by bending the main keel plate 1 itself. The top of the secondary keel plate 2 has a bent portion 7, which is formed by bending the top of the secondary keel plate 2 itself. The bent portion 7 is horizontally arranged and perpendicular to the secondary keel plate 2, and bends inward. The bent portion 7 can improve the supporting strength of the secondary keel plate 2, and at the same time, it can increase the top surface area of ​​the secondary keel plate 2. Since it bends inward, it further improves the safety of the support frame.

[0037] The support frame is equipped with a connector for hanging the support frame. In this embodiment, the connector is a hanging rope 8, with both ends of the hanging rope 8 fixed to the side walls of the two keel plates 2, which can be secured by bolts or rivets. By setting the hanging rope 8, when the support frame is used on an air conditioner cleaning cover, the support frame and the air conditioner cleaning cover can be hung together on the air conditioner via the hanging rope 8.

[0038] The fixing points at both ends of the hanging rope 8 are symmetrical, and the fixing points of the hanging rope 8 are close to the hinge end of the secondary keel plate 2, making it easier for the hanging rope 8 to be connected to the air conditioner, and the force is more balanced when water accumulates in the flexible pool body 9.

[0039] like Figure 4As shown, in other embodiments, the hanging rope 8 may include a first connecting rope 801 and a second connecting rope 802. One end of the first connecting rope 801 is fixed to one of the keel plates 2, and the other end is provided with a snap-locking self-locking tensioner 803 (or snap-locking tensioner, binding strap tensioner, rope tightener). One end of the second connecting rope 802 is fixed to another keel plate 2, and the other end is connected to the snap-locking self-locking tensioner 803, so that the length of the connector can be adjusted to match different models of air conditioners and enhance applicability. The second connecting rope 802 passes through the snap-locking self-locking tensioner 803. When the snap-locking is pressed down, the spikes on the snap-locking are locked onto the second connecting rope, fixing the second connecting rope 802. The more the second connecting rope 802 passes through, the shorter the connector becomes, and vice versa. The snap-locking self-locking tensioner 803 is prior art, and its use for rope length adjustment is common knowledge; its structure will not be described in detail. In other embodiments, the connector can also be a hook fixed on the two side secondary keel plates 2 respectively, so that the two hooks can be used to hang the two ends of the air conditioner to achieve fixation.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
