[0015] Figure 1 It is a three-dimensional diagram of the utility model;
[0016] Figure 2 It is a front view of the utility model;
[0017] Figure 3 It is a side view of the utility model. DETAILED DESCRIPTION
[0018] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.
[0019] like Figure 1-Figure 3As shown, an armrest zero-pressure chair comprises two front support rods 1 hinged to each other and two rear support rods 2 hinged to each other, an adjustment structure is arranged between the front support rods 1 and the rear support rods 2, the adjustment structure comprises two adjustment components, the two adjustment components are respectively connected to the front support rods 1 and the rear support rods 2, the adjustment components comprise a first adjustment rod 3, a second adjustment rod 4, a third adjustment rod 12, a front support seat 6, a front base 5, a rear support seat 8 and a rear base 7, the front support seat 6 is hinged to the upper end of the front support rod 1, the front base 5 is hinged to the bottom end of the front support rod 1, the rear support seat 8 is hinged to the rear end of the rear support rod 2 The upper end is hinged, the rear base 7 is hinged to the bottom end of the rear support rod 2, the two ends of the first adjusting rod 3 are hinged to the front base 5 and the rear support seat 8 respectively, the two ends of the second adjusting rod 4 are hinged to the front support seat 6 and the rear base 7 respectively, the first adjusting rod 3 and the second adjusting rod 4 are cross-hinged, the two ends of the third adjusting rod 12 are hinged to the first adjusting rod 3 and the second adjusting rod 4 respectively, and the hinges of the third adjusting rod 12 and the first adjusting rod 3 and the hinges of the third adjusting rod 12 and the second adjusting rod 4 are close to the front support rod 1, and the third adjusting rod 12 and the first adjusting rod 3 are hinged through a connecting piece.
[0020] The armrest zero-pressure chair has two states, an open state and a folded state.
[0021] In the open state, the front support rod 1 and the rear support rod 2 are opened, and the distance between the front support rod 1 and the rear support rod 2 is pulled apart, that is, the first adjustment rod 3, the second adjustment rod 4 and the third adjustment rod 12 are opened, and then the open state of the chair is formed, and at the same time, the seat cushion can ensure that the user can sit.
[0022] Among them, after the user sits on the chair, the back leans against the cushion cloth, and the spring rod 10 will be stretched. Due to the limiting effect of the rear support seat 8, the stretching distance of the spring rod 10 can be controlled to control the reclining angle of the backrest. After the user stands up, the spring rod 10 automatically resets.
[0023] In the folded state, the front support rod 1 and the rear support rod 2 are folded, and the distance between the front support rod 1 and the rear support rod 2 is folded at the same time, that is, the first adjustment rod 3, the second adjustment rod 4 and the third adjustment rod 12 are folded, and then the chair is formed in the folded state.
[0024] A slot is provided on the rear support seat 8, in which a spring rod 10 is provided. The bottom end of the spring rod 10 is hinged to the second adjusting rod 4 through a connecting piece, and a connecting rod 11 is provided between the upper end of the spring rod 10 and the hinge between the first adjusting rod 3 and the second adjusting rod 4.
[0025] Specifically, the front base 5 and the rear base 7 are in an arc shape, and the angle corresponding to the arc is 90 degrees, so that when the entire chair is folded up, an enclosure is formed between the front base 5 and the rear base 7 for easy storage.
[0026] Specifically, the direction of the slot is consistent with the swinging direction of the spring rod 10, ensuring that the spring rod 10 can be effectively limited by the slot when swinging.
[0027] Specifically, a sliding groove is provided at the hinge between the front support seat 6 and the front support rod 1 to ensure that the front support rod 1 can be opened and closed in the sliding groove on the front support seat 6 when opening and closing, thereby ensuring the reliability of the opening and closing of the front support rod 1.
[0028] Specifically, it also includes a seat cushion cloth, which passes through the spring rod 10 and the front support rod 1 in sequence, and the seat cushion cloth is located above the front support seat 6 and the rear support seat 8. In this way, after the user sits on the seat cushion cloth, the seat cushion cloth at the spring rod 10 can support the user's back, and the space formed between the front support seat 6 and the rear support seat 8 is used for the user to sit, and the front support rod 1 of the seat cushion cloth is limited.
[0029] Specifically, a handrail 9 is provided at the top end of the front support rod 1 .
[0030] The above is based on the enlightenment of this utility model. Through the above description, relevant staff can make various changes and modifications without deviating from the technical idea of this utility model. The technical scope of this utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
