Description

Technical Field

[0001] This utility model relates to the field of baby rocker technology, specifically to a rocker support leg structure and a baby rocker containing the same. Background Technology

[0002] A rocking chair is a type of seating that uses a curved base or elastic mechanism to rock back and forth, serving both recreational and decorative purposes. It is widely used in homes, medical settings, and childcare facilities. Common types of rocking chairs include traditional wooden rocking chairs, modern casual rocking chairs, rattan rocking chairs, and electric rocking chairs. Traditional rocking chairs (such as wooden rocker-style or spring-suspended types) primarily achieve their rocking function through physical mechanics. Modern casual rocking chairs feature cushions and can rotate or rock, commonly found in Scandinavian-style homes. Rattan rocking chairs are breathable and lightweight, suitable for patios or balconies. Electric rocking chairs, with massage and heating functions, are suitable for the elderly or pregnant women.

[0003] The rocker arm is the core component of a rocking chair. It is a double-arc structure made of wood, metal, or plastic, and achieves its rocking function through physical and mechanical principles. Although rocking chair technology is relatively mature, the following problems still exist: the rocker arm structure of existing rocking chairs begins to sway under external force, failing to maintain stability when needed, thus limiting its application scenarios. For example, a Chinese utility model patent with publication number CN205947532U discloses a children's rocking chair, including a rocker arm supported on the ground and a backrest arm. The rocker arm extends in the front-to-back direction and has a downward-convex arc structure. The backrest arm is inclined upwards from front to back, and its lower end is rotatably connected to the front end of the rocker arm. The rocking chair also includes a support rod for supporting the backrest arm and defining its position. One end of the support rod is rotatably connected to one of the backrest arm and rocker arm, and the other end of the support rod is detachably mounted on the other of the backrest arm and rocker arm, and its position can be adjusted. This children's rocking chair has a simple structure and can be stabilized in the unfolded state without the need for a locking mechanism. However, the rocker arm structure cannot be locked relative to the ground, meaning it cannot remain stable when needed by the user. Utility Model Content

[0004] The technical problem solved by this utility model is that the rocker arm structure of the existing rocking chair will start to sway when subjected to external force, and cannot remain stable when needed.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A rocking chair support leg structure, comprising:

[0007] The connecting part is fixedly connected to the rocker arm of the rocking chair and is located at the end of the rocker arm structure;

[0008] A support portion, which is rotatably connected to the connecting portion, wherein at least one end of the support portion can contact the ground;

[0009] A locking structure is provided to lock the relative rotation between the support and the connecting part.

[0010] In one embodiment of this utility model, the connecting part is fixedly connected to the rocker arm by a pin.

[0011] In one embodiment of this utility model, the connecting part is a plate-like structure.

[0012] In one embodiment of this utility model: the connecting part includes a side plate and an end plate, the two end plates are arranged in parallel and fixedly disposed at both ends of the side plate, and the dimension between the two end plates is consistent with the dimension of the rocker arm.

[0013] In one embodiment of this utility model, the support portion has a C-shaped structure.

[0014] In one embodiment of this utility model: the end of the support portion is provided with an anti-slip protrusion.

[0015] In one embodiment of this utility model: a first adapter is fixedly provided on the connecting part, and a second adapter is fixedly provided on the supporting part. The first adapter and the second adapter are rotatably connected by a rotating shaft.

[0016] In one embodiment of this utility model: a transition notch is formed between two first adapters, and the second adapter is located within the transition notch.

[0017] In one embodiment of this utility model: the locking structure includes a locking protrusion and a locking piece. The locking protrusion is hemispherical and is fixedly disposed on the first adapter. The locking piece is fixedly connected to the support portion and has a locking notch.

[0018] An infant rocker includes the aforementioned rocker support leg structure.

[0019] The rocking chair support leg structure and the baby rocking chair containing the present invention have at least one of the following technical effects:

[0020] This application includes a connecting part and a supporting part, with the supporting part rotatably connected to the connecting part. The connecting part is fixedly connected to the rocker arm structure of the rocker. The supporting part has at least two states: a retracted state and a lowered state. A locking structure ensures that the supporting part remains stable in both the retracted and lowered states. In the retracted state, the orientation and height of the supporting part are approximately similar to those of the connecting part connected to the rocker arm (connecting rod). At this time, the rocker arm can perform its normal swinging function, and the rocker will swing when subjected to external force. When the supporting part is in the lowered state, the free end of the supporting part faces downward and can contact the ground. At this time, the supporting part lifts one end of the rocker arm, allowing the entire rocker to maintain a stable state, thus meeting the needs of users in special situations. For example, when it is necessary to place an infant on the rocker for feeding, it is obviously better for the rocker to remain stable. Compared with existing rocker products, this device has a simple structure, is easy to adjust, can meet customer usage needs, and can adapt to more usage scenarios. The end of the support part used to support the ground can be inclined relative to the main body of the support part. In this way, when the contact surface is in contact with the ground, the support part can be in an inclined state, forming a triangular shape with the rocker arm and the ground, which is more stable.

[0029] 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, and 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.

[0030] Please see Figure 1 This utility model relates to an infant rocker, including but not limited to a rocker structure 1 supported on the ground. The rocker structure 1 extends in the front-to-back direction and has a downward-convex arc shape (double arc structure) in the middle to enable rocking. The rocker structure 1 includes two parallel arc-shaped rods and a connecting rod for connecting the two arc-shaped rods. The connecting rod can be located at the end of the arc-shaped rods and can be configured as a single unit.

[0031] Please see Figure 1 In one embodiment of this utility model, the baby rocker may further include a support structure, which is inclined upwards from front to back. The support structure may be fixedly connected to one end of the rocker arm structure 1, or it may be rotatably connected to the end of the rocker arm, i.e., the lower end of the support structure is rotatably connected to the front end of the rocker arm, allowing for adjustment according to usage. When rotatably connected, a corresponding locking structure, such as a pin or buckle, may be provided at the rotatable connection position. A toy rod may be connected to the support structure, and a toy block may be fitted onto the toy rod for the baby to play with. A swing head may also be provided on the support structure, which is fixedly installed on the support structure via a swing rod and located above the baby's lying position. This provides a certain degree of fun for the baby to play with. The rocker may also include a reclining structure (not shown in the figure) for the baby to lie down. The reclining structure may be a plate-like structure connected to the support structure, or a layered structure made of fabric.

[0032] Please see Figure 1-5In one embodiment of this utility model, a rocking chair support leg structure is also provided. This rocking chair support leg structure is used on the rocker arm structure 1 of a rocking chair, particularly on the rocker arm structure 1 of an infant rocking chair. Specifically, the rocking chair support leg structure includes a connecting part 2, a supporting part 3, and a locking structure. The connecting part 2 is fixedly connected to the rocker arm of the rocking chair and is located at the end of the rocker arm structure 1. When a connecting rod is provided between two rocker arms, the connecting part 2 can be installed on the connecting rod. The connecting part 2 is used to fix the support leg structure to the rocker arm of the rocking chair. The connection method can be a detachable installation connection, such as a connection using a bolt structure. It can also be a fixed connection, such as the connecting part 2 being fixedly connected to the rocker arm by a pin. Specifically, as an example, the connecting part 2 is a plate-shaped structure, the shape of which matches the contour of the rocker arm at the installation position. Then, the two are fixedly connected by a connector. Preferably, the connecting part 2 may include a side plate and an end plate. The two end plates are arranged in parallel and fixedly disposed at both ends of the side plate, and the dimension between the two end plates is the same as the dimension of the rocker arm. The two end plates and the side plate can be an integral structure, forming a U-shaped structure, which can partially cover the rocker arm and then be fixedly connected by fasteners, thus ensuring the stability of the connection between the connecting part 2 and the rocker arm.

[0033] Please see Figure 2-5 In one embodiment of this utility model, the support part 3 is rotatably connected to the connecting part 2, and at least one end of the support part 3 can contact the ground. The support part 3 can be configured as a rod-shaped structure, with one end rotatably connected to the connecting part 2 and the other end being a free end that can contact the ground when rotated downwards. As another example of the support part 3, the support part 3 can be C-shaped. Its central position is rotatably connected to the connecting part 2, and its two ends can contact the ground when facing downwards. The support part 3 can be a plate-shaped structure with a U-shaped cross-section, and several reinforcing ribs are fixedly arranged inside to ensure the strength of the support part 3. The end of the support part 3 that contacts the ground can be provided with anti-slip protrusions. The anti-slip protrusions can be strip-shaped or dot-shaped anti-slip protrusions to ensure stability when the end of the support part 3 contacts the ground.

[0034] Please see Figure 2-5In one embodiment of this utility model, the connection method between the support part 3 and the connecting part 2 can be designed according to actual conditions. As an example, a first adapter is fixedly provided on the connecting part 2, and a second adapter is fixedly provided on the support part 3. The first adapter and the second adapter are rotatably connected via a rotating shaft. Further, there can be two first adapters, positioned inside the rocker arm. A connection notch is formed between the two first adapters, and the second adapter is located within the connection notch. The first adapter and the second adapter are then rotatably connected via a rotating shaft to ensure connection stability.

[0035] Please see Figure 2-5 In one embodiment of this utility model, the locking structure is used to lock the relative rotation between the support part 3 and the connecting part 2, so that the support part 3 can remain stable after being adjusted to the target position. The locking structure can be a plug-in locking component such as a pin or dowel. It can also be set as a nut lock sleeved on the rotating shaft, which is loosened during adjustment and tightened after adjustment. As a preferred example, the locking structure includes a locking protrusion and a locking plate 4. The locking protrusion is hemispherical and fixedly disposed on the side of the first adapter. The spherical surface of the locking protrusion faces the locking plate 4 for cooperating with the locking plate 4. The locking plate 4 is fixedly connected to the support part 3. The locking plate 4 has a locking notch. The locking plate 4 can be circular, and the locking notch is disposed on the edge contour of the locking plate 4. The number of locking notches is at least two. When the locking protrusion is located in one locking notch, the support part 3 can be stabilized in the retracted state. When the locking protrusion is located in another locking notch, the support part 3 can be stabilized in the lowered state. The free end of the support part 3 is in contact with the ground at this time, providing support for the rocking chair and ensuring its stability.

[0036] The working principle of this utility model:

[0037] This application includes a connecting part 2 and a supporting part 3, with the supporting part 3 rotatably connected to the connecting part 2. The connecting part 2 is fixedly connected to the rocker arm structure 1 of the rocker chair. The supporting part 3 has at least two states: a retracted state and a lowered state. A locking structure ensures that the supporting part 3 remains stable regardless of whether it is in the retracted or lowered state. In the retracted state, the orientation of the supporting part 3 is approximately the same as the orientation and height of the connecting part 2 connected to the rocker arm (connecting rod). Figure 5 At this time, the rocker arm of the rocking chair can perform its normal swinging function, and the rocking chair will swing when it receives an external force. When the support part 3 is in the lowered state, the free end of the support part 3 faces downward and can contact the ground (e.g., Figure 1 , 2(3) At this point, the rocker arm is lifted by the support part 3, allowing the entire rocker to remain stable and meet the needs of users in special situations. For example, when feeding an infant, it is obviously better for the rocker to remain stable. Compared with existing rocker products, this device has a simple structure, is easy to adjust, and can meet customer needs and adapt to more usage scenarios. The end of the support part 3 that supports the ground can be tilted relative to the main body of the support part 3. Thus, when the contact surface is in contact with the ground, the support part 3 can be in a tilted state, forming a triangular shape with the rocker arm and the ground, resulting in greater stability.
