Description

Technical Field

[0001] The utility model relates to the technical field of child seats, in particular to an ISOFIX component of a child safety seat. Background Art

[0002] In the prior art, the ISOFIX connector includes an outer frame, a plurality of gear holes are provided on the top of the outer frame, a sliding inner part is slidably arranged in the outer frame, and the sliding inner part includes a propulsion device, a hook, a gear adjustment mechanism, and a gear locking plate are arranged in the propulsion device, and a locking head is arranged on the top of the gear locking plate, such as a child safety seat ISOFIX device disclosed in Publication (Announcement) No.: CN215663076U, an ISOFIX connector disclosed in Publication (Announcement) No.: CN218448580U, an ISOFIX connector disclosed in Publication (Announcement) No.: CN111823970A, and an ISOFIX connector disclosed in Publication (Announcement) No.: CN211567744U, all of which have only one locking head.

[0003] When a locking head is set, in order to ensure the reliability and stability of the connection, the locking head needs to have a large contact area with the gear hole. In order to ensure the strength of the shell, the size and spacing of the gear holes are usually large, which makes the adjustment distance between adjacent gears large and cannot achieve high-precision adjustment. It is easy to create a gap between the locking head and the backrest of the car seat, causing shaking. Utility Model Content

[0004] The utility model aims to provide an ISOFIX assembly for a child safety seat, which can effectively solve the problems in the background technology.

[0005] The technical solution to achieve the above object is: an ISOFIX assembly for a child safety seat, comprising an outer frame, a plurality of gear holes are provided on the top of the outer frame, a sliding inner part is provided inside the outer frame, and the sliding inner part includes a gear locking plate;

[0006] The invention is characterized in that: the top of the gear locking plate is provided with at least two locking heads protruding upwards and respectively matched and locked in different gear holes on the outer frame, and the locking heads are matched and locked with the same number of continuously adjacent gear holes.

[0007] Furthermore, one side of the locking head in the locking direction is set as a vertical surface, and the other side is set as an inclined surface, so that the locking head forms a triangle with the small end facing outward.

[0008] Furthermore, the gear locking plate includes two identical plates stacked on top of each other.

[0009] Furthermore, one end of the gear locking plate away from the locking head is rotatably mounted in the sliding inner part.

[0010] Further, the sliding inner member further includes a slider. A V-shaped locking groove is provided at one end of the gear locking piece away from the rotation mounting end. The slider is slidably arranged left and right relative to the gear locking piece and cooperates with the locking groove to control the rotation of the gear locking piece around the rotation end, realizing the locking and unlocking control of the gear locking piece.

[0011] Advantages of the present utility model:

[0012] Under the condition that the mutual locking force between the outer frame and the sliding inner member (the force that can pull the locking piece of the sliding inner member out of the gear hole of the outer frame is called the locking force) remains unchanged, at least two locking heads are provided on the gear locking piece of the present utility model, so as to evenly distribute the mutual locking force, which can reduce the distance between the connected gear holes, enable the gear holes on the outer frame to be arranged more densely. For example, it can be changed from 8 gear holes to 16 gear holes, making the adjustment distance of each gear smaller, realizing finer adjustment, reducing or even avoiding the gap generated between the backrest of the car seat during use, and reducing the shaking after installation.

[0017] As Figures 1-4 shown, the present utility model discloses an ISOFIX assembly for a child safety seat, including an outer frame 1. A plurality of gear holes 2 are provided at the top of the outer frame 1. A sliding inner member 3 is slidably arranged in the outer frame 1. The sliding inner member 3 includes a gear locking piece 5 and a slider 8. One end of the gear locking piece 5 is rotatably installed in the sliding inner member 3. A V-shaped locking groove 10 is provided at one end of the gear locking piece 5 away from the rotation mounting end. The slider 8 is slidably arranged left and right relative to the gear locking piece 5 and cooperates with the locking groove 10 to control the rotation of the gear locking piece 5 around the rotation end, realizing the locking and unlocking control of the gear locking piece 5.

[0018] The above structure belongs to the prior art. Specifically, it can but is not limited to adopt the structure of a child safety seat ISOFIX device disclosed in the publication number: CN215663076U, which will not be elaborated here.

[0019] The main innovation of the present utility model lies in that: at least two locking heads 7 protruding upward are provided at the top of the gear locking piece 5, and the locking heads 7 are respectively adapted to be locked in continuously adjacent different gear holes 2. As a preference of this embodiment, two locking heads 7 are provided.

[0020] Under the condition that the mutual locking force between the outer frame 1 and the sliding inner member 3 of the present utility model remains unchanged (the force that can pull the locking piece of the sliding inner member out of the gear hole of the outer frame is called the locking force), at least two locking heads 7 are provided on the gear locking piece 5 of the present utility model, so as to evenly distribute the mutual locking force, reduce the distance between the connected gear holes 2, enable the gear holes 2 on the outer frame to be arranged more densely. For example, it can be changed from 8 gear holes to 16 gear holes, make the adjustment distance of each gear smaller, realize more precise adjustment, reduce or even avoid the gap generated between the backrest of the vehicle seat during use, and reduce the shaking after installation.

[0021] As a preference of this embodiment, the gear locking piece 5 includes two identical and mutually laminated sheets. Of course, one sheet or more than two sheets can also be provided.

[0022] One side of the locking head 7 in the locking direction (i.e., the direction of arrow A in the figure) is set as a vertical surface, and the other side is set as an inclined surface, so that the locking head 7 forms a triangle with the small end facing outwards. When the gear locking piece 5 needs to move away from the gear hole 2, the single-sided inclined surface is more likely to slide out of the gear hole 2. When the gear locking piece 5 enters the gear hole 2, the single-sided vertical surface contacts the cross-section of the gear hole 2 and is not easy to slide out of the gear hole 2, thus ensuring the strength when the ISOFIX component is connected to the vehicle fixing point.

[0023] As a preference of this embodiment, the peripheral wall of the gear hole 2 is non-arc-shaped, which is more conducive to the stability when contacting the gear locking piece 5.

[0024] During use, when the slider 8 presses the lower inclined surface of the locking groove 10 of the gear locking piece 5 to the left, the gear locking piece 5 rotates downward around the rotation point, so that the locking head 7 moves away from the gear hole 2. Similarly, when the slider 8 moves away from the lower inclined surface of the locking groove 10, the gear locking piece 5 resets under the action of the spring, so that the locking head 7 re-enters the gear hole 2.
