Description

Technical Field

[0001] This utility model relates to the field of office chair technology, and in particular to an integrated sitting and standing office chair. Background Technology

[0002] Office chairs refer to chairs used by general office workers. Depending on the needs of different industries, office chairs come in a variety of styles. Currently, common office chairs typically include only a seat, a backrest at the rear of the seat, armrests on both sides of the seat, and support legs at the bottom of the seat to support it.

[0003] For example, Chinese patent CN220236446U discloses an integrated sitting and standing office chair, including an office chair chassis, a base on the top of the office chair chassis, a backrest adjustment device on the right side of the backrest, and an armrest adjustment device on the front of the base. The backrest adjustment device includes a connecting frame, a connecting column, a limiting slide, a limiting slide rod, a limiting slide groove, a first backrest plate, a second backrest plate, a side connecting seat, an insertion block, an adjusting base plate, and mounting bolts.

[0004] However, in current technology, most integrated office chairs cannot be adjusted according to the user's different height, weight, leg length, and body type, making it difficult for users to find the most comfortable sitting posture. Maintaining this uncomfortable sitting posture for a long time not only increases fatigue and may even cause physical pain, but also distracts the user, thereby reducing work efficiency. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art and to propose an integrated sitting and standing office chair.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A seat-standing office chair includes a chair body, a support leg rotatably connected to the bottom of the chair body, an armrest fixedly connected to the top of the chair body, an adjustment mechanism installed on the side wall of the chair body, and a headrest installed on the top of the chair body.

[0008] The adjustment mechanism includes a fixed plate, a first lifting frame slidably connected inside the fixed plate, the top of the first lifting frame penetrating through the fixed plate, a rotating frame rotatably connected to the top of the fixed plate, the top of the rotating frame being fixedly connected to the bottom of the headrest, a second lifting frame fixedly connected to the side wall of the first lifting frame, a guide hole provided in the side wall of the fixed plate, the second lifting frame being slidably connected to the guide hole, a lumbar pillow installed inside the chair body, and a limit hole provided in the side wall of the chair body, one end of the second lifting frame penetrating through the guide hole, and one end of the second lifting frame being fixedly connected to the lumbar pillow.

[0009] Preferably, a fixing block is fixedly connected to the side wall of the fixing plate, and a handle is installed on one side of the fixing block.

[0010] Preferably, one end of the handle is fixedly connected to a plug rod, and one end of the plug rod passes through the fixing block.

[0011] Preferably, a limiting plate is installed inside the fixing block, and the limiting plate is fixedly connected to the outer surface of the plug rod.

[0012] Preferably, the side wall of the first lifting frame is provided with multiple insertion holes, and the insertion rod can be inserted into the insertion holes.

[0013] Preferably, a spring is installed inside the fixing block, and the spring is sleeved on the surface of the plug rod.

[0014] Preferably, the diameters of the limiting plate and the handle are both larger than the diameters of the through holes on both sides of the fixing block.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. This utility model precisely adjusts the height of the headrest through the first lifting frame to ensure optimal head support, improve comfort, and reduce neck fatigue. The rotating frame allows the headrest angle to be freely adjusted, and the self-locking mechanism ensures stable support. When the first lifting frame is raised or lowered, the second lifting frame slides accordingly. The guide hole ensures stable sliding without deviation. The second lifting frame drives the lumbar pillow to move through the limiting hole, realizing adaptive adjustment of lumbar support and effectively relieving discomfort caused by prolonged sitting.

[0017] 2. When the first lifting frame of this utility model is raised or lowered, the spring releases its elastic force, pushes the limiting plate, and then drives the insertion rod to move. When the insertion rod is aligned with the hole on the fixed plate, it completely penetrates the fixed plate and connects with the insertion hole on the lifting frame to form a stable connection, ensuring the stability of the lifting frame. During adjustment, the user operates the handle to move the limiting plate towards the spring, squeezing and compressing the spring to provide space for the insertion rod to be pulled out. The spring not only pushes the limiting plate to move, ensuring the precise insertion of the insertion rod, but also provides compression space during adjustment, ensuring the reliability and durability of the positioning mechanism. The entire positioning mechanism is ingeniously designed and easy to operate, providing an important guarantee for the stability and safety of the lifting frame. Attached Figure Description

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a seat-standing integrated office chair, including a chair body 1, a support leg 2 rotatably connected to the bottom of the chair body 1, an armrest 3 fixedly connected to the top of the chair body 1, an adjustment mechanism 6 installed on the side wall of the chair body 1, and a headrest 4 installed on the top of the chair body 1.

[0027] The adjustment mechanism 6 includes a fixed plate 62, a first lifting frame 61 is slidably connected inside the fixed plate 62, the top of the first lifting frame 61 passes through the fixed plate 62, a rotating frame 65 is rotatably connected to the top of the fixed plate 62, the top of the rotating frame 65 is fixedly connected to the bottom of the headrest 4, a second lifting frame 63 is fixedly connected to the side wall of the first lifting frame 61, a guide hole 64 is provided on the side wall of the fixed plate 62, the second lifting frame 63 is slidably connected to the guide hole 64, a lumbar pillow 5 is installed inside the chair body 1, and a limit hole 51 is provided on the side wall of the chair body 1, one end of the second lifting frame 63 passes through the guide hole 64, and one end of the second lifting frame 63 is fixedly connected to the lumbar pillow 5.

[0028] The specific settings and functions of this embodiment will be described in detail below. Through the precise adjustment of the first lifting frame 61, the user can fine-tune the height of the headrest 4 according to their own needs to ensure optimal head support. This not only improves the comfort of use but also helps reduce neck fatigue and discomfort caused by prolonged sitting.

[0029] In addition to being height-adjustable, the headrest 4 can be freely adjusted within a certain range via the rotating frame 65 to better accommodate different sitting and head postures. The self-locking mechanism of the rotating frame 65 ensures that the headrest 4 remains stable after being adjusted to a suitable angle, preventing unintentional shifting and providing users with more stable and reliable support.

[0030] During the height adjustment of the headrest 4, the lifting action of the first lifting frame 61 is also linked to the second lifting frame 63. This design cleverly utilizes mechanical principles, allowing the second lifting frame 63 to slide along with the first lifting frame 61. To ensure smooth and stable sliding, the second lifting frame 63 is limited by the guide hole 64. The guide hole 64 is precisely and ingeniously designed; it not only provides the necessary guidance but also prevents the second lifting frame 63 from shifting or wobbling during sliding.

[0031] As the second lifting frame 63 slides, it is further constrained by the limiting hole 51, causing the lumbar pillow 5 to move accordingly. This design allows the lumbar pillow 5 to automatically adjust its position according to the user's height and sitting posture, ensuring optimal support for the user's lower back.

[0032] Example 2: Figure 3 - Figure 5 As shown, a fixing block 66 is fixedly connected to the side wall of the fixing plate 62, and a handle 67 is installed on one side of the fixing block 66. A plug-in rod 69 is fixedly connected to one end of the handle 67, and one end of the plug-in rod 69 passes through the fixing block 66. A limiting plate 691 is installed inside the fixing block 66, and the limiting plate 691 is fixedly connected to the outer surface of the plug-in rod 69. Multiple plug-in holes 611 are opened on the side wall of the first lifting frame 61, and the plug-in rod 69 can be inserted into the plug-in holes 611. A spring 68 is installed inside the fixing block 66, and the spring 68 is sleeved on the surface of the plug-in rod 69. The diameters of the limiting plate 691 and the handle 67 are both larger than the diameters of the through holes on both sides of the fixing block 66.

[0033] The overall effect of this embodiment is that when the first lifting frame 61 is raised or lowered, the elastic force of the spring 68 is gradually released, pushing the limiting plate 691 to move accordingly. The limiting plate 691 is closely connected to the plug-in rod 69, so it will drive the plug-in rod 69 to move together. As the first lifting frame 61 is raised or lowered, the plug-in rod 69 will gradually approach the fixed plate 62.

[0034] When the connector rod 69 aligns with the hole on the fixed plate 62, it continues to move forward until it completely penetrates the fixed plate 62. At this point, the end of the connector rod 69 accurately aligns with the connector hole 611 on the first lifting frame 61, forming a stable connection. This connection ensures the stability of the lifting frame and prevents it from moving or lifting arbitrarily.

[0035] When adjustments to the lifting frame are needed, the user can unlock the positioning mechanism by operating handle 67. Handle 67 is connected to limit plate 691; the user only needs to gently push handle 67 to move limit plate 691 toward spring 68. During this process, limit plate 691 compresses spring 68. This compression provides the necessary space for the insertion rod 69 to be pulled out of insertion hole 611.

[0036] Spring 68 plays a crucial role in the entire positioning mechanism. It not only pushes the movement of the limit plate 691 during lifting and lowering, ensuring the precise insertion of the connector rod 69, but is also compressed during adjustment, providing space for the connector rod 69 to be pulled out. Furthermore, the elasticity of spring 68 ensures the reliability and durability of the positioning mechanism. Here, the length, strength, and other specifications of spring 68, as well as its shock-absorbing structure, can be selected and set according to actual needs.

[0037] The device's usage and working principle are as follows: The height of the headrest 4 can be effectively controlled via the lifting function of the first lifting frame 61, allowing for easy adjustment to suit the user's body size and ensure proper head support. During adjustment, the rotating frame 65 has a self-locking function, enabling the headrest 4 to be freely adjusted to a suitable angle to support the user's head.

[0038] Furthermore, when the first lifting frame 61 rises or falls, it simultaneously drives the second lifting frame 63 to slide. During this process, the second lifting frame 63 is limited by the guide hole 64, ensuring that it rises and falls with the first lifting frame 61. At the same time, under the further restriction of the limiting hole 51, the second lifting frame 63 will drive the lumbar pillow 5 to move, thereby adjusting the position of the lumbar support for the user.

[0039] During the lifting and lowering process of the first lifting frame 61, the elasticity of the spring 68 can push the limiting plate 691 to move, thereby causing the limiting plate 691 to move together with the plug rod 69. In this way, the plug rod 69 can accurately pass through the fixing plate 62 and be plugged into the plug hole 611, thus facilitating the positioning of the first lifting frame 61 and preventing it from moving or lifting and lowering arbitrarily.

[0040] During adjustment, the user can operate the limit plate 691 and the insertion rod 69 by using handle 67. In this process, the limit plate 691 compresses the spring 68 to facilitate accurate positioning when needed.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
