Detailed Description

Examples

The sitting and lying dual-purpose office chair provided by the embodiment comprises a bottom plate 1, two armrest frames 2 arranged on the bottom plate 1, a back support plate 3 arranged on the side end of the bottom plate 1 and hinged to the bottom plate 1, two adjusting units 4 respectively arranged on the two armrest frames 2 and connected to the side end of the back support plate 3, and a horizontal support frame unit 5 arranged on the side end of the back support plate 3, as shown in the attached drawing 1.

In this embodiment, the base plate 1, the two armrest frames 2 and the back support plate 3 form a basic office chair structure, and the support legs on the lower surface of the base plate 1 can be selected from a hydraulic device or other height-adjustable structures in the prior art, so that the detailed description is omitted; the dual-purpose function of sitting and lying of the device is realized by connecting the back support plate 3 and the side end of the bottom plate 1 in a hinged manner, and the specific hinged structure is not limited; on the basis, the device is also provided with adjusting units 4 on the handrail frames 2 at two ends to be connected with two ends of the back support plate 3, and the structure at least comprises the following advantages: firstly, the adjusting unit 4 is obliquely arranged and used for dragging and fixing two ends of the back support plate 3 in a sitting state, so that stress at the hinged position of the back support plate 3 and the bottom plate 1 is dispersedly reduced, and the service life is prolonged; secondly, the adjusting unit 4 can be detached, and the back support plate 3 and the bottom plate 1 can be completely folded when detached, so that the occupied space is reduced, and the carrying and the transportation are convenient; thirdly, the structure of the office chair is enriched by the structure of the adjusting unit 4, and the aesthetic property is enhanced. In this embodiment, the bottom plate 1, two handrail frames 2 and the outside protective sheath of all can overlapping the different materials of back backup pad 3 to adapt to different official working scene demands.

In this embodiment, as shown in fig. 2 and 3, the adjusting unit 4 includes an installation hole 401 disposed on one side of the armrest frame 2 close to the back support plate 3 and disposed obliquely, a fixing snap ring 402 disposed on the side end of the back support plate 3, a connecting rod 403 having two ends inserted into the installation hole 401 and the fixing snap ring 402, respectively, a first limit nut 404 disposed on the end of the connecting rod 403 close to the installation hole 401, and a second limit nut 405 disposed on the end of the connecting rod 403 close to the fixing snap ring 402. In this embodiment, in order to ensure the traction effect of the adjusting unit 4, the included angle between the connecting rod 403 and the horizontal plane is generally 40 ° to 80 °, which is determined by the opening angle of the mounting hole 401, so that the angle between the back support plate 3 and the bottom plate 1 is not adjustable when the device is in a sitting state, and the stability is good. The fixing snap ring 402 is an open ring in this embodiment, and is preferably made of a material with certain elasticity, so that the connecting rod 403 can be directly snapped into the opening; the second limiting nut 405 is used for avoiding the connecting rod 403 from sliding downwards, so that the stability is improved.

In this embodiment, connecting rod 403 one end directly passes mounting hole 401, and through first stop nut 404 carries out spacing fixed to the tip of connecting rod 403, because connecting rod 403 has certain inclination, consequently with there is the contained angle between the support body of handrail frame 2, the influence the spacing fixed action of first stop nut 404, consequently, adjusting unit 4 is still including setting up on the connecting rod 403 and being located on the inboard end of handrail frame 2 and through the inclined plane protective sheath 406 that the mode of jack-up is connected with first stop nut 404. As shown in fig. 4, one end of the inclined protective sleeve 406 is an inclined surface for being attached to the surface of the armrest frame 2, and the other end of the inclined protective sleeve is attached to the first limit nut 404, so that the included angle space between the first limit nut 404 and the frame body of the armrest frame 2 is filled, and the stability is improved. The beveled protective sleeve 406 is preferably made of a material having some elasticity to reduce wear.

In this embodiment, as shown in fig. 1 and 3, the adjusting unit 4 further includes a fixing hole 407 disposed on the base plate 1 and used for inserting the connecting rod 403. The advantage that sets up like this lies down, only need follow the one end of connecting rod 403 the stationary clasp 402 shifts out, then will connecting rod 403 slides down along original inclination all the time, until most connecting rod 403 is located bottom plate 1 lower extreme, whole connecting rod 403 just can be hidden, avoids influencing the user. In a preferred hidden state of this embodiment, the connecting rod 403 slides down until the second limiting nut 405 is fastened to the surface of the mounting hole 401, and the connecting rod 403 and the first limiting nut 404 all pass through the fixing hole 407 and are located at the lower end of the bottom plate 1; further, an arc-shaped structure or a protective sleeve (not shown) may be disposed at an end of the connecting rod 403 where the second limiting nut 405 is disposed, so as to avoid collision.

In this embodiment, as shown in fig. 5 and 6, the horizontal supporting frame unit 5 includes an installation groove 501 disposed at a side end of the back supporting plate 3, a fixing post 502 disposed on an inner wall of the installation groove 501, a rotating supporting frame 503 having one end sleeved on the fixing post 502 and using the fixing post 502 as an axis, an elastic pad 504 disposed on an end of the rotating supporting frame 503 away from the fixing post 502, an engaging groove 506 disposed on the inner wall of the installation groove 501 and configured to be engaged with the elastic pad 504, and a reinforcing cross bar 505 disposed on the rotating supporting frame 503. In this embodiment, the elastic pad 504 can reduce the abrasion and noise generated between the rotating support frame 503 and the ground, and can enter the engaging groove 506 through force application and force application, so as to ensure that the whole rotating support frame 503 rocks or even falls off in the mounting groove 501 in the sitting state; the reinforcing cross bar 505 can reinforce the supporting effect of the rotating support frame 503, and can also be used as a handle for rotating the rotating support frame 503 out of the mounting groove 501, so that the comfort of a user is improved.

The working principle of the embodiment is as follows: in a sitting state, one end of the connecting rod 403 is inserted into the mounting hole 401 and is respectively sleeved into the protective sleeve 406 and the first limiting nut 404 at the end part for fixation, and the other end of the connecting rod 403 is clamped into the fixing snap ring 402 and is fixed through the second limiting nut 405. When needs switch over to the state of lying, shift out from fixed snap ring 402 with connecting rod 403 one end earlier to in following the incline direction gliding and inserting the fixed orifices 407 with the connecting rod 403 other end, until second stop nut 405 and mounting hole 401 surface block, then the supporting leg height of adjusting bottom plate 1 lower extreme holds reinforcing horizontal pole 505 at last, follows rotation support frame 503 the play is until perpendicular to ground in the mounting groove 501, can lie.
