Abstract
Description
[Technical Field]
[0001] This utility model relates to the field of children's travel products technology, and in particular to a rotating locking mechanism for a baby basket. [Background Technology]
[0002] As a portable carrying tool, infant car seats are widely used in scenarios such as infant travel (e.g., connecting an infant car seat to a stroller base) and storing everyday items (e.g., using a shopping basket with a stroller). To ensure the stability of the connection between the car seat and the base (e.g., stroller base, car mount, etc.), a locking mechanism is usually required. The two are locked together by the cooperation of the locking element and the locking part on the base. When it is necessary to separate the car seat from the base, an unlocking operation is required to disengage the locking element from the locking part.
[0003] Currently, most existing basket locking mechanisms use a "pull-cord linkage" structure for unlocking. This involves a pull-cord attached to the basket, with one end connected to the user's control (such as a handle or pull ring) and the other end extending to the bottom of the basket and connecting to the locking mechanism. When the user pulls the cord, the traction force causes the locking mechanism to slide, disengaging it from the locking part of the base, thus unlocking the basket. However, this pull-cord linkage unlocking method has the following significant drawbacks:
[0004] Firstly, the transmission timeliness is poor. Because the pull cord itself has a certain degree of elasticity, it is prone to lag due to stretching and deformation during the pulling process. In addition, the pull cord needs to pass through the guide hole on the basket or go around the guide wheel. The contact friction with the guide component will further reduce the efficiency of the pull force transmission. As a result, after the user pulls the pull cord, the locking part cannot respond to the sliding immediately, and there is a significant delay in the unlocking action, which affects the user experience and may even cause safety hazards in emergency separation scenarios (such as when the infant basket needs to be quickly removed from the stroller).
[0005] Secondly, the linkage effect is prone to failure after long-term use. As a flexible component, the pull rope is subject to friction with guide components (such as hole walls and pulleys) during repeated pulling, leading to surface wear, fraying, and even breakage. Simultaneously, the pull rope, constantly exposed to the external environment, is susceptible to corrosion from dust, moisture, or chemicals, accelerating aging and increasing the embrittlement of the internal fibers. These problems can result in reduced effective pulling force of the pull rope, misalignment of the transmission path, and potential issues such as rope jamming, incomplete sliding of the locking component (inability to fully unlock), or unexpected automatic unlocking during unlocking. These issues severely affect the reliability of the locking mechanism and the safety of the basket.
[0006] In addition, the arrangement of the pull ropes must take into account the movement space of the basket (such as the travel distance when the basket rotates relative to the base), and sufficient length must be reserved to avoid the pull ropes being too tight. However, this further exacerbates the problem of inaccurate transmission caused by the slack of the pull ropes.
[0007] Therefore, this utility model was developed to address the aforementioned problems. [Utility Model Content]
[0008] The purpose of this invention is to overcome the shortcomings of the prior art and provide a rotating locking mechanism for a baby carrier. The unlocking component adopts a rigid structure and is directly and rigidly linked to the rotating seat through a second linkage component. When the user operates the unlocking operation part, the rotation of the unlocking component can be transmitted to the rotating seat without delay. The rotating seat then drives the locking component to slide synchronously through the first linkage component, realizing a full-link rigid transmission of "operation-rotation-sliding". This significantly improves the timeliness and accuracy of the unlocking action, and is especially suitable for emergency scenarios where the baby carrier needs to be quickly separated from the base, such as when the baby carrier is urgently detached from the stroller.
[0009] This utility model is achieved through the following technical solution:
[0010] A rotating locking mechanism for a basket includes a locking member 1, a rotating seat 3, and an unlocking member 5 with a rigid structure. The locking member 1 is slidably disposed on the bottom of the basket 100 and is used to lock and engage with the locking part of the base 200. The rotating seat 3 is rotatably disposed on the bottom of the basket 100. A first linkage component 2 is provided between the rotating seat 3 and the locking member 1 to link the locking member 1 to slide accordingly when the rotating seat 3 rotates relative to the basket 100. The unlocking member 5 is rotatably disposed on the side of the basket 100 at its middle or upper part. The upper part of the unlocking member 5 extends to the lifting position of the basket 100 to form an unlocking operation part 51 for user operation. A second linkage component 4 is provided between the lower end of the unlocking member 5 and the rotating seat 3 to link the rotating seat 3 to rotate accordingly when the unlocking member 5 rotates relative to the basket 100.
[0011] As described above, in a rotating locking mechanism for a basket, the middle or upper part of the unlocking member 5 is pivotally connected to the side of the basket 100 via a first pivot, and the rotating seat 3 is pivotally connected to the bottom of the basket 100 via a second pivot. The first pivot and the second pivot are offset and perpendicular to each other.
[0012] As described above, in a rotating locking mechanism for a basket, the first linkage component 2 includes a first linkage rod 21 and a first arc-shaped hole 22 disposed between the rotating seat 3 and the locking member 1 and interconnected therewith.
[0013] As described above, in a rotating locking mechanism for a basket, the first linkage rod 21 is provided on the locking member 1, and the first arc-shaped hole 22 is eccentrically provided on the rotating seat 3.
[0014] As described above, in a rotating locking mechanism for a basket, two first arc-shaped holes 22 are symmetrically arranged and their common ends are connected, and the first linkage rod 21 is located at the common end position of the two first arc-shaped holes 22.
[0015] As described above, in a rotating locking mechanism for a basket, the second linkage component 4 includes a first drive rod 41 and a first strip hole 42 disposed between the unlocking member 5 and the rotating seat 3. The first drive rod 41 is rotatably and slidably placed in the first strip hole 42.
[0016] As described above, in a rotating locking mechanism for a basket, the first drive rod 41 is located at the lower end of the unlocking member 5, and the first strip hole 42 is eccentrically located on the rotating seat 3.
[0017] As described above, in a rotating locking mechanism for a basket, an unlocking elastic reset member 6 is provided between the unlocking member 5 and the basket 100 for driving the unlocking member 5 to elastically reset.
[0018] As described above, in a rotating locking mechanism for a basket, an unlocking guide assembly 7 is provided between the unlocking member 5 and the side of the basket 100 to guide the rotation path of the unlocking member 5.
[0019] As described above, in a rotating locking mechanism for a basket, the unlocking guide assembly 7 includes a guide arc-shaped hole 71 and a guide rod 72 located between the lower part of the unlocking member 5 and the side of the basket 100, which can guide and cooperate with each other.
[0020] Compared with the prior art, the present invention has the following advantages:
[0021] 1. The unlocking component in this utility model adopts a rigid structure, which is directly and rigidly linked with the rotating seat through the second linkage component. When the user operates the unlocking operation part, the rotation of the unlocking component can be transmitted to the rotating seat without delay. The rotating seat then drives the locking component to slide synchronously through the first linkage component, realizing the full-link rigid transmission of "operation-rotation-sliding", which significantly improves the timeliness and accuracy of the unlocking action. It is especially suitable for emergency scenarios that require quick separation of the carrier and the base, such as the emergency separation of the infant carrier from the stroller.
[0022] 2. In this utility model, the unlocking component, rotating seat, and locking component are all rigid parts. The first linkage assembly and the second linkage assembly also use rigid contact transmission, which avoids the aging and wear problems of flexible parts. Even with long-term high-frequency use, the transmission accuracy and matching relationship of each component can remain stable, effectively reducing the risk of jamming, incomplete sliding of the locking component, or accidental automatic unlocking, and greatly improving the durability and reliability of the locking mechanism. At the same time, the rigid linkage structure reduces the number of parts (no need for pull ropes, multiple pulleys, etc.), further simplifying the assembly process and reducing production and manufacturing costs.
[0023] 3. This utility model rotatably sets the unlocking component of the rigid structure on the side of the basket. Its rotation trajectory is highly compatible with the spatial layout of the basket. Unlike the pull rope, it does not require additional guide holes, winding wheels or slack space. This helps to reduce the overall size of the locking mechanism and is more suitable for the basket's lightweight and compact design requirements.
[0024] 4. The two first arc-shaped holes are symmetrically arranged and their same ends are connected. The first linkage rod is located at the same end of the two first arc-shaped holes, which allows users or assemblers to complete the assembly directly by aligning the holes without having to identify the "left / right" markings, thus significantly reducing the difficulty and time cost of installation.

Detailed Implementation Methods
[0034] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0035] like Figure 1-8As shown, this utility model discloses a rotating locking mechanism for a basket, including a locking member 1, a rotating seat 3, and an unlocking member 5 with a rigid structure. The locking member 1 is slidably disposed on the bottom of the basket 100 and is used to lock and engage with the locking part of the base 200. The rotating seat 3 is rotatably disposed on the bottom of the basket 100. A first linkage component 2 is provided between the rotating seat 3 and the locking member 1 to link the locking member 1 to slide accordingly when the rotating seat 3 rotates relative to the basket 100. The unlocking member 5 is rotatably disposed on the side of the basket 100 in the middle or upper part. The upper part of the unlocking member 5 extends to the lifting position of the basket 100 to form an unlocking operation part 51 for user operation. A second linkage component 4 is provided between the lower end of the unlocking member 5 and the rotating seat 3 to link the rotating seat 3 to rotate accordingly when the unlocking member 5 rotates relative to the basket 100. In this invention, the unlocking component adopts a rigid structure, which is directly and rigidly linked to the rotating seat through the second linkage component. When the user operates the unlocking operation unit, the rotation of the unlocking component can be transmitted to the rotating seat without delay. The rotating seat then drives the locking component to slide synchronously through the first linkage component, realizing a full-link rigid transmission of "operation-rotation-sliding". This significantly improves the timeliness and accuracy of the unlocking action, and is especially suitable for emergency scenarios where the carrier and the base need to be separated quickly, such as when the infant carrier is urgently detached from the stroller.
[0036] In this invention, the unlocking component, rotating seat, and locking component are all rigid parts. The first and second linkage components also use rigid contact transmission, which avoids the aging and wear problems of flexible components. Even with long-term high-frequency use, the transmission accuracy and matching relationship of each component can remain stable, effectively reducing the risk of jamming, incomplete sliding of the locking component, or accidental automatic unlocking, and greatly improving the durability and reliability of the locking mechanism. At the same time, the rigid linkage structure reduces the number of components (no need for pull ropes, multiple pulleys, etc.), further simplifying the assembly process and reducing production and manufacturing costs.
[0037] like Figure 2 , 3 As shown in Figures 5 and 6, a complex array of locking components 1 are spaced apart along the circumference of the rotating base 3 on the bottom of the basket. Together with corresponding locking parts on the base, they can achieve locking of the basket relative to the base in several directions, such as forward, backward, left, and right. Figure 3 , 5 As shown in Figures 6 and 7, each of the locking members 1 is provided with a locking elastic member between itself and the bottom of the basket for driving the locking member 1 to elastically reset.
[0038] The unlocking component 5 is pivotally connected to the side of the basket 100 via a first pivot, and the rotating seat 3 is pivotally connected to the bottom of the basket 100 via a second pivot. The first pivot and the second pivot are offset and perpendicular to each other, so that their rotation paths do not intersect in space, completely avoiding motion interference of the linkage components, ensuring that the movement of each component is smooth and without jamming when unlocking, and significantly improving the smoothness of user operation.
[0039] like Figure 1 , 2 As shown in Figures 5 and 6, the first linkage component 2 includes a first linkage rod 21 and a first arc-shaped hole 22 disposed between the rotating base 3 and the locking member 1 and interconnected therewith. Preferably, the first linkage rod 21 is disposed on the locking member 1, and the first arc-shaped hole 22 is eccentrically disposed on the rotating base 3. This embodiment avoids the "cosine effect" that may occur in traditional direct-connection rods through the transmission method of "circular arc track - linear sliding", which can accurately control the sliding distance and direction of the locking member 1, ensure that the fitting depth of the locking part between the locking member 1 and the locking part of the base 200 is consistent, and significantly improve the stability of the locking state and the thoroughness of unlocking.
[0040] like Figure 1 , 2 As shown in Figures 5 and 6, the two first arc-shaped holes 22 are symmetrically arranged and their common ends are connected. The first linkage rod 21 is located at the common end position of the two first arc-shaped holes 22, which allows users or assemblers to complete the assembly directly by aligning the holes without having to identify the "left / right" markings, significantly reducing the installation difficulty and time cost.
[0041] like Figure 3 , 5 As shown in Figure 6, to achieve high efficiency in unlocking operations, low interference in component movement, and long-term reliability, the second linkage assembly 4 includes a first drive rod 41 and a first strip hole 42 disposed between the unlocking member 5 and the rotating seat 3. The first drive rod 41 is rotatably and slidably placed within the first strip hole 42. The first drive rod 41 is located at the lower end of the unlocking member 5, and the first strip hole 42 is eccentrically located on the rotating seat 3. To reduce installation difficulty, the two first strip holes 42 are symmetrically located on the rotating seat 3. During unlocking, the user operates the unlocking operation part 51, causing the lower part of the unlocking member 5 to rotate forward around the first pivot. The unlocking member 5 drives the rotating seat 3 to rotate accordingly through the corresponding inner wall of the first drive rod 41 and the first strip hole 42. The rotating seat 3 drives the locking member 1 to slide accordingly through the corresponding inner wall of the first arc-shaped hole 22 and the first linkage rod 21, until the locking member separates from the locking part of the base.
[0042] like Figure 1-6As shown, in order to improve the ease of operation and efficiency, an unlocking elastic reset member 6 is provided between the unlocking member 5 and the basket 100 to drive the unlocking member 5 to elastically reset.
[0043] like Figure 1-6 As shown, to ensure the rotation process of the unlocking component is precise, smooth, and reliable, an unlocking guide assembly 7 is provided between the unlocking component 5 and the side of the basket 100 to guide the rotation path of the unlocking component 5. The unlocking guide assembly 7 includes a guide arc-shaped hole 71 and a guide rod 72 located between the lower part of the unlocking component 5 and the side of the basket 100 and capable of guiding and cooperating with each other.
