Description

Technical Field

[0001] The utility model relates to the technical field of furniture, in particular to a detachable chair. Background Art

[0002] Chairs are indispensable in daily life and work. At present, the chairs commonly used in people's daily life are basically composed of a seat, a chair back and legs supporting the seat.

[0003] In the prior art, when transporting a seat, merchants usually divide the seat into small parts in order to save transportation space, and then put them into a cardboard box; after receiving the cardboard box, the user installs the seat. Merchants usually provide a connecting plate, the lower part of which is connected to the seat plate by bolts, and the upper part of which is connected to the backrest by bolts, so that the backrest and the seat plate are assembled.

[0004] However, there are some difficulties in the above installation steps: when the connecting plate and the seat plate are connected by bolts, the threaded holes on the connecting plate need to be aligned with the threaded holes on the seat plate, and then the bolts are screwed in. However, when the bolts are screwed in, the connecting plate will tilt, which requires the user to hold the connecting plate straight with one hand and screw in the bolts with the other hand; similarly, when the connecting plate and the backrest are connected by bolts, the backrest will tilt, so the user needs to hold the backrest straight with one hand and screw in the bolts with the other hand. The above two difficulties make installation very difficult for users who are weak and install the chair alone. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a detachable chair for solving the technical problem that some detachable chairs mentioned in the background art are very difficult to install for users who have little strength and install the chair alone.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] A detachable chair comprises a seat plate and a support leg arranged at the bottom of the seat plate, wherein a support plate is fixedly provided at the bottom of the seat plate, a mounting seat is fixedly provided at a side of the support plate away from the seat plate, the mounting seat is a hollow structure and is penetrated from top to bottom; a connecting plate is detachably provided inside the mounting seat, a first supporting assembly is provided inside the mounting seat, and the first supporting assembly is used to limit the connecting plate; a backrest is detachably provided above the connecting plate, a second supporting assembly is connected between the backrest and the connecting plate, and the second supporting assembly is used to limit the backrest; a lifting seat is provided on the side of the seat plate close to the backrest, a cushion is detachably provided inside the lifting seat, and the cushion can slide vertically inside the lifting seat and can also slide horizontally.

[0008] Working principle:

[0009] During installation, the connecting plate is placed inside the mounting seat, and at the same time, the first supporting assembly limits the connecting plate, and then the user manually locks the connecting plate and the mounting seat;

[0010] After the connecting plate is fixed, the backrest is connected to the connecting plate. At the same time, the second supporting component limits the backrest, and then the user manually locks the backrest and the connecting plate;

[0011] After the backrest is fixed, the cushion is arranged inside the lifting seat and fixed, and the vertical position of the cushion is adjusted by moving the cushion vertically; and the position of the cushion is adjusted by moving the cushion horizontally.

[0012] Beneficial effects:

[0013] In this solution, a connecting plate is provided, the lower part of which is connected to the seat plate by bolts, and the upper part of which is connected to the backrest by bolts, so that the backrest and the seat plate are assembled. This design of dividing the seat into small parts can save transportation space.

[0014] By providing the first support assembly and the second support assembly, the connection plate and the backrest are limited respectively, so that when the user screws in the bolts to fix the connection plate and the backrest, the connection plate and the backrest are prevented from falling, thereby increasing the user's operating strength;

[0015] By setting a lifting seat, it is easy to install and disassemble the cushion, and the vertical and horizontal positions of the cushion can also be adjusted to adapt to different users, which is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS
