Description

Technical Field

[0001] This utility model belongs to the field of seat back cushion technology, specifically relating to a reliably installed seat back cushion. Background Technology

[0002] Currently, existing seat back cushions can be used to attach the chair back and seat together using clips. Existing technology generally uses independent clips, meaning the clips are fixed to the chair back or seat using screws or other methods. However, the installation of the seat cushion and backrest using existing technology is not convenient or reliable enough. Utility Model Content

[0003] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a reliably installed seat back cushion.

[0004] A reliably installed seat back cushion includes a seat, a mounting plate, and a seat back, and further includes: a first snap-fit ​​portion disposed on the seat, wherein the first snap-fit ​​portion includes a snap-fit ​​block assembly, the snap-fit ​​block assembly includes snap-fit ​​blocks, and the mounting plate is provided with a snap-fit ​​groove that matches the snap-fit ​​blocks; it also includes a clamping member, wherein the first snap-fit ​​portion further includes a one-way snap-fit ​​groove, and the clamping member passes through the seat back and the one-way snap-fit ​​groove and is fixedly connected to the mounting plate.

[0005] As a further improved technical solution, the snap-fit ​​block is provided in multiple ways; the unidirectional snap-fit ​​slot is provided on both sides of the snap-fit ​​block group.

[0006] As a further improved technical solution, the cross-section of the snap-fit ​​block is a right-angled triangle, and the right-angled side of the snap-fit ​​block abuts against the snap-fit ​​groove.

[0007] As a further improved technical solution, the unidirectional card slot includes a card slot body, and elastic baffles are provided on both sides of the card slot body.

[0008] As a further improved technical solution, a support plate is also included, the support plate including a backrest connection part and a seat connection part, wherein the backrest connection part is connected to the backrest by screws, and the seat connection part is fixed to the seat by the clamping member.

[0009] As a further improved technical solution, the chair seat is provided with a second connecting groove that is adapted to the chair seat connecting part, and the chair seat connecting part is fixed in the second connecting groove by the clamping member.

[0010] The beneficial effects are as follows: During installation, the mounting plate and the chair back are connected by a clamping component, leaving a certain gap between the mounting plate and the chair back. The chair seat is then partially inserted into this gap, and the locking block engages with the locking slot. The one-way locking slot also engages with the clamping component, and then the clamping component is tightened. Installation is convenient, quick, and the connection is reliable.

[0011] At the same time, setting up a slot also has the benefits of reducing the material and weight of the mounting plate and lowering costs. Attached Figure Description

Detailed Implementation

[0015] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0016] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0017] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0018] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0019] Reference Figures 1-6 A reliably installed seat back cushion includes a seat 100, a mounting plate 200, a seat back 300, and a first snap-fit ​​portion disposed on the seat 100. The first snap-fit ​​portion includes a snap-fit ​​block assembly 140, which includes snap-fit ​​blocks 110. The mounting plate 200 is provided with a snap-fit ​​groove 210 that matches the snap-fit ​​blocks 110. The cushion also includes a clamping member 400. The first snap-fit ​​portion further includes a one-way snap-fit ​​groove 120. When the seat back cushion is installed, the clamping member 400 passes through the seat back 300 and the one-way snap-fit ​​groove 120 and is fixedly connected to the mounting plate 200.

[0020] The clamping component 400 can be made of commonly used screws or other connecting parts.

[0021] During installation, the mounting plate 200 and the backrest 300 are connected by the clamping member 400, leaving a certain gap between them. The seat 100 is then partially inserted into this gap, and the locking block 110 engages with the locking groove 210, while the one-way locking groove 120 engages with the clamping member 400. Finally, the clamping member 400 is tightened. Installation is convenient, quick, and the connection is reliable.

[0022] At the same time, the design of the card slot 210 also has the benefits of reducing the material and weight of the mounting plate 200 and lowering costs.

[0023] In this embodiment, multiple snap-fit ​​blocks 110 are provided; the one-way snap-fit ​​grooves 120 are provided on both sides of the snap-fit ​​block group 140, which improves the strength of the reliably installed backrest cushion.

[0024] In this embodiment, the cross-section of the snap-fit ​​block 110 is a right-angled triangle, and the right-angled side of the snap-fit ​​block 110 abuts against the snap-fit ​​groove 210. This design facilitates the installation of the chair seat 100 and the support member 200, but makes it difficult to detach the connection after installation.

[0025] In this embodiment, the unidirectional card slot 120 includes a card slot body 121, and elastic baffles 122 are respectively provided on both sides of the card slot body 121.

[0026] In a preferred embodiment, a support plate 500 is further included, which includes a backrest connecting portion 510 and a seat connecting portion 520. The backrest connecting portion 510 is connected to the backrest by screws, and the seat connecting portion 520 is fixed to the seat 100 by the clamping member 400. The support plate 500 is used to support the backrest 300.

[0027] In a preferred embodiment, the chair seat 100 is provided with a second connecting groove 130 that is adapted to the chair seat connecting part 520, and the chair seat connecting part 520 is fixed in the second connecting groove 130 by the clamping member 400.

[0028] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
