[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] Example 1

[0024] An office chair for a comfortable lunch break, such as Figure 1 As shown, it includes a mobile office chair, a flip positioning structure, a reclining chair frame and a foldable leg rest board 17.

[0025] The flip positioning structure includes a fixed slot 9, a rotation positioning slot 10 and a positioning pin 8; the backrest 2 of the mobile office chair is movably connected to the chassis 1 through the flip positioning structure. The backrest 2 is a curved design and is provided with a waist guard to better fit the human waist curve. A neck support 5 is fixedly provided on the top. A pair of backrest support rods 6 are formed on the left and right sides of the bottom of the backrest 2. A pair of chassis rear support rods 7 are correspondingly formed on the rear side of the bottom surface of the chassis 1. A fixed slot 9 is formed on the chassis rear support rod 7, and a rotation positioning slot 10 is provided on the backrest support rod 6. The two are connected by the flip positioning structure.

[0026] The positioning pin 8 is composed of a circular shaft section and a positioning section. The positioning section is a circular shaft with a pair of positioning protrusions 11 symmetrically formed on the side, and a circular shaft section is formed at one end, and an umbrella-shaped pull-out handle 12 is fixed at the other end. The fixed slot 9 is movably connected with the positioning section of the positioning pin 8. The rotation positioning slot 10 is composed of a circular hole section and a slot section, and both parts of the rotation positioning slot 10 are movably matched with the circular shaft section of the positioning pin 8. There are also three pairs of positioning notches (when the angle between the backrest 2 and the base 1 is 0°, 45° and 90°, respectively) arranged around the side wall of the slot section for plugging and matching with the positioning protrusion 11. Pull the pull-out handle 12 to pull out part of the positioning pin 8. At this time, the positioning section of the positioning pin 8 is matched with the fixed slot 9, and the rotation positioning slot 10 is movably matched with the circular shaft section, so that the backrest can be rotated; after rotating to the corresponding position, press the pull-out handle 12, and the positioning section is matched with the fixed slot 9 and the rotation positioning slot 10 at the same time, and the backrest is fixed. By inserting the positioning protrusion 11 into different positioning slots, the chair back is fixed in a back-leaning state, a reclining state or a lying state.

[0027] The reclining chair frame includes supporting legs 13, connecting rods 15, reinforcing rods 4 and rockers 14; a pair of connecting supports 16 for connecting the reclining chair frame are formed on both sides of the bottom surface of the chassis 1, the upper ends of the pair of supporting legs 13 are respectively connected to the connecting supports through the set flip positioning structure (fixing slots 9 are formed on the supporting legs 13, and rotating positioning slots 10 are provided on the connecting supports 16), and the lower ends are fixed with rockers 14, which are S-shaped (the curvature is similar to the curve of the chair back 2), and the two ends of a connecting rod 15 are respectively connected and fixed to the rockers 14 on both sides, and at the same time, the two ends of the reinforcing rod 4 are respectively connected and fixed to the middle of the supporting legs 13 and the rockers 14, and two reinforcing rods 4 are provided. When the reclining chair frame is fixed in the supporting state by the flip positioning structure, the rockers are placed flat on the ground and stably support the mobile office chair; when the reclining chair frame is lifted and fixed in the storage state, the rockers 14 are placed behind the chair back 2.

[0028] The foldable leg rest plate 17 is a U-shaped plate structure with a cushion layer on the surface. A pair of parallel connecting ear plates 19 are formed at the bottom of the U-shaped plate, and a fixed slot 9 is formed on the left connecting ear plate 19. A circular hole that is movably sleeved with the circular shaft segment of the positioning pin 8 is formed on the other side. The foldable leg rest plate 17 is installed on the front support 18 of the chassis formed on the front side of the chassis 1 through the positioning pin 8 (a rotating positioning slot 10 is provided at the front end of the chassis front support 18). The foldable leg rest plate 17 can be flattened or flipped back to the bottom of the chassis 1 under the action of the flipping positioning structure (after being retracted, the U-shaped opening of the foldable leg rest plate 17 avoids the gas rod).

[0029] The flip positioning structure and its carrier (such as the backrest support rod 6 and the connecting support 16) are all made of metal and have excellent hardness. The reclining chair frame is made of metal as a whole, and the rocker 14 is made of high-strength plastic-coated steel, and the ground surface is provided with a rubber anti-skid layer.

[0030] In the specific implementation of this embodiment:

[0031] When using it for office, Figure 2 As shown, the chair back 2 is fixed in the seat state, the foldable leg rest 17 is stored at the bottom of the chassis 1, and the reclining chair frame is flipped to the back of the chair back 2, and the user sits on the office chair and leans on the chair back 2.

[0032] During lunch break, Figure 1 or Figure 3 As shown, pull the pull handle 12 and flip the chair back 2 to a reclining state or a lying state, then return the pull handle 12 to fix the state of the chair back 2, unfold the foldable leg rest board 17 in the same way, and make the reclining chair frame support the mobile office chair, so as to obtain a reclining chair for taking a lunch break.

[0033] Example 2

[0034] An office chair for a comfortable lunch break, based on Example 1, for positions where flip positioning structures are set on both sides, only the flip positioning structure on one side can be set, and the other side can be replaced by a hinge connection method (for example, a hinge connection between a backrest support rod 6 on one side and a rear support rod 7 on the chassis). This makes it more convenient for users to adjust the flip parts of the office chair, but it will reduce the load-bearing capacity and is suitable for people with small weight.

[0035] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
