Technical Field

[0001] This utility model relates to the field of seating technology, and more specifically, to a detachable seat. Background Technology

[0002] In existing technologies, seats typically employ a one-piece design or are assembled using fasteners such as screws and bolts. This design has several drawbacks: firstly, one-piece seats occupy significant space during transportation and storage, increasing logistics costs; secondly, seats connected by fasteners require tools for assembly and disassembly, making the process cumbersome, and repairing or replacing damaged components is difficult, often requiring complete removal and resulting in resource waste. Therefore, there is an urgent need for a seat structure that facilitates assembly and disassembly, saves space, and allows for easy component repair and replacement to address these issues.

The terms "vertical," "horizontal," "left," "right," "above," "below," and similar expressions are for illustrative purposes only and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed or operated in a specific orientation, and therefore should not be construed as limiting the invention.

[0025] To make the objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein.

[0026] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] This utility model provides a detachable seat, such as Figure 1-8 As shown, it includes a support assembly 1, a seat plate 2, and a back plate 3; the seat plate 2 is detachably connected to the support assembly 1 via a snap-fit ​​structure, and the back plate 3 is detachably connected to the seat plate 2 via a snap-fit ​​structure.

[0028] As a further preferred embodiment, the support assembly 1 includes a metal tube support bracket 11 for supporting the seat plate 2 and two inverted trapezoidal metal tube side brackets 12; one side of the metal tube support bracket 11 is fixedly connected to one of the metal tube side brackets 12, and the other side is fixedly connected to the other metal tube side bracket 12; each metal tube side bracket 12 is provided with an anti-slip pad 121 at its bottom.

[0029] Specifically, the support assembly 1 is the supporting frame of the entire seat, comprising a metal tube load-bearing support 11 and two inverted trapezoidal metal tube side supports 12. The metal tube load-bearing support 11 is horizontally positioned to directly support the seat plate 2; its left side is fixedly connected to one metal tube side support 12, and its right side is fixedly connected to the other metal tube side support 12, forming a stable support structure. Each metal tube side support 12 has two anti-slip pads 121 at its bottom to enhance the seat's stability and anti-slip performance. The support assembly 1 is made of steel tubing, manufactured through bending and welding processes, and its surface is coated with an anti-rust coating to extend its service life. Figure 1 and Figure 8 The overall structure of the seat is shown, in which the inverted trapezoidal design of the support component 1 ensures even weight distribution. Figures 3 to 5 The metal tube support bracket 11 is shown to have a slight backward tilt (the front end is slightly higher than the rear end, so that...). Figure 2 The metal card 111 (shown in the direction shown, with the right side being the rear) is used to engage with the first snap-fit ​​structure 21 of the base plate 2.

[0030] As a further preferred embodiment, the seat plate 2 is an L-shaped plastic seat plate with an accommodating space, and its bottom is provided with a first snap-fit ​​connection part 21 that is adapted to the metal tube support bracket 11, and its upper end is provided with a second snap-fit ​​connection part 22 that is adapted to the back plate 3.

[0031] As a further preferred embodiment, the first snap-fit ​​connection part 21 is a slot structure with a plurality of elastic claws 211, and the slot structure is engaged with the metal card 111 of the metal tube support bracket 11.

[0032] Specifically, the seat plate 2 is an L-shaped plastic component with accommodating space, which reduces weight while ensuring strength. Its bottom has a first snap-fit ​​connection part 21 for connecting to the metal tube support bracket 11 of the bracket assembly 1; its upper end has a second snap-fit ​​connection part 22 for connecting to the back plate 3. The first snap-fit ​​connection part 21 is a slot structure with three equally spaced elastic claws 211 (see...). Figure 5 The elastic claw 211 can be elastically deformed and engage with the metal clip 111 of the metal tube support bracket 11, achieving quick fixation without tools. The top of the seat plate 2 is also provided with a handle 23, which is tilted upwards and backwards to facilitate the user to move the seat or hang items such as backpacks. Figure 3 The exploded view of the seat clearly shows the separation state of the seat plate 2 and the support assembly 1. Figure 5 The magnified view shows the engagement relationship between the elastic claw 211 of the first snap-fit ​​connection part 21 and the metal card 111, demonstrating its guiding and locking mechanism.

[0033] As a further preferred embodiment, the back plate 3 is a plastic back plate with a hollow structure, and its back is provided with a third buckle connection part 31 that is adapted to the seat plate 2.

[0034] As a further preferred embodiment, the third snap-fit ​​connection part 31 is an elastic snap-fit ​​311 with a guide bevel, and the elastic snap-fit ​​311 is engaged with the second snap-fit ​​connection part 22.

[0035] Specifically, the back panel 3 is a plastic back panel with a hollow structure, which is both aesthetically pleasing and breathable. This utility model provides, for example... Figure 1 and Figure 8 The two structures are shown. The back of the back plate 3 is provided with a third snap-fit ​​connection part 31 for connecting with the second snap-fit ​​connection part 22 of the seat plate 2. The third snap-fit ​​connection part 31 is at least one elastic snap 311 with a guide bevel (see...). Figure 6 When the elastic buckle 311 is inserted into the second buckle connecting part 22, it automatically engages via a beveled guide, and locks in place after elastic deformation, ensuring a secure connection. An anti-loosening post 32 is integrally formed at the upper end of the back plate 3, above the elastic buckle 311. When the back plate 3 is engaged in the preset position, the anti-loosening post 32 engages precisely in the corresponding slot of the base plate 2. An automatic screw passes through this slot and drills into the screw hole inside the anti-loosening post 32, further securing the back plate 3 and the base plate 2 together. The hollow design of the back plate 3 also reduces the overall weight.

[0036] The assembly process of this utility model is as follows: First, align the base plate 2 with the metal tube support bracket 11 of the bracket assembly 1 via the first snap-fit ​​connection part 21, press down, and then push back 3-5 cm to engage the elastic claw 211 with the metal clip 111. When the base plate 2 can no longer move backward, it indicates that the connection is in place. Then, align the third snap-fit ​​connection part 31 of the back plate 3 with the second snap-fit ​​connection part 22 of the base plate 2, and gently push it in. The elastic snap 311 will automatically lock. If necessary, self-tapping screws can be screwed onto the anti-loosening post 32 for further tightening. Disassembly is performed by reversing the operation.

[0037] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
