Description

Technical Field

[0001] This utility model relates to the field of office chair technology, and in particular to an office chair that prevents fatigue and reduces muscle strain. Background Technology

[0002] Office chairs that prevent fatigue and reduce muscle strain typically refer to ergonomic chairs. They are adjustable, with features such as seat height, depth, and tilt angle, armrest height, and backrest angle and height all adjustable to adapt to different body needs, ensuring smooth blood circulation and preventing excessive pressure on any part of the body. Simultaneously, they offer excellent support, conforming to the spinal curve and featuring lumbar support to reduce pressure on the lower back, maintain the spine's natural position, and effectively alleviate fatigue and muscle strain caused by prolonged office work.

[0003] Ergonomic chairs typically consist of a backrest, base, headrest, armrests, gas spring, and legs. Their working principle involves scientifically designing each part to conform to the natural curves of the human body. For example, the backrest conforms to the spine's curve for support, the lumbar support maintains the lumbar lordosis to reduce lower back pressure, the seat cushion adapts to the curves of the hips and legs, and the armrests support the arms. Combined with adjustable features, they can be personalized to different body characteristics, thereby reducing body pressure and relieving fatigue.

[0004] In existing technologies, some ergonomic chairs cannot store small items. Without storage space, small items are placed randomly and may be accidentally knocked to the ground or covered by documents, making them difficult to find or even lost. The loss of important small parts, memory cards, etc. can be inconvenient. Therefore, an office chair that prevents fatigue and reduces muscle strain is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an office chair that prevents fatigue and reduces muscle strain, aiming to improve the problem that existing ergonomic chairs cannot store small items.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An office chair designed to prevent fatigue and reduce muscle strain includes a base, an armrest fixedly connected to the outside of the base, a button slidably connected to the inner wall of the armrest, a slide plate fixedly connected to the outside of the button, a slider fixedly connected to the end of the slide plate away from the button, a sliding sleeve slidably connected to the end of the slider away from the slide plate, two springs fixedly connected to the outside of the sliding sleeve, a locking block fixedly connected to the end of the sliding sleeve away from the two springs, a top block slidably connected to the inner wall of the armrest, a limit plate fixedly connected to the outside of the top block, a second spring fixedly connected to the end of the limit plate away from the top block, a cover plate rotatably connected to the outside of the armrest, a locking plate fixedly connected to the outside of the cover plate, a pull plate fixedly connected to the outside of the cover plate, and a sliding assembly for sliding subsequent components fixedly connected to the outside of the base.

[0008] As a further description of the above technical solution:

[0009] The sliding assembly includes a storage plate, the outside of which is fixedly connected to the outside of the base. An extension plate is slidably connected to the inner wall of the storage plate. A slot is provided on the outside of the extension plate. A support plate is slidably connected to the inner wall of the extension plate. A sliding column is fixedly connected to the outside of the support plate. A locking column is fixedly connected to the inner wall of the support plate.

[0010] As a further description of the above technical solution:

[0011] The outer side of the skateboard is slidably connected to the inner wall of the handrail, and the outer side of the slider is slidably connected to the inner wall of the handrail.

[0012] As a further description of the above technical solution:

[0013] The outer side of the sliding sleeve is slidably connected to the inner wall of the handrail, and one end of the spring away from the sliding sleeve is fixedly connected to the inner wall of the handrail.

[0014] As a further description of the above technical solution:

[0015] The card block is externally slidably connected to the inner wall of the handrail, and the limiting plate is externally slidably connected to the inner wall of the handrail.

[0016] As a further description of the above technical solution:

[0017] The end of the second spring away from the limiting plate is fixedly connected to the inner wall of the handrail, the outer side of the locking block is movably connected to the outside of the locking plate, and the end of the top block away from the limiting plate is in contact with the outside of the locking block.

[0018] As a further description of the above technical solution:

[0019] The sliding column is externally slidably connected to the inner wall of the extension plate, and the locking column is externally movably connected to the inner wall of the locking groove.

[0020] As a further description of the above technical solution:

[0021] The outer side of the card plate is slidably connected to the inner wall of the handrail, and the outer side of the card post is in contact with the inner wall of the extension plate.

[0022] The beneficial effects of this utility model are as follows:

[0023] (1) This utility model uses a button connected to the armrest above the base to press. The button applies pressure to the slider through the slide plate, causing the slider to move inside the slide sleeve. Since the contact surface between the slider and the slide sleeve is a symmetrical slope, the lateral force will be converted into the longitudinal force. Therefore, the slide sleeve will move the locking block towards the first spring and squeeze the first spring. At this time, the first spring will compress the space to ensure that the locking block has enough space to leave the locking plate and no longer lock. The second spring connected inside the armrest releases potential energy to the top block through the limiting plate because the locking plate and the locking block are no longer locked. This causes the locking plate to move above the locking block. In this way, the entire cover can be moved away from the armrest and no longer closed by lifting the pull plate connected to the cover plate. Then, items can be put into the inside of the armrest for storage, which improves the utilization rate of the office chair and facilitates the quick storage of items.

[0024] (2) This utility model involves pulling out the handle connected to the inner tray of the storage plate under the base, and then pulling out the inner extension plate of the storage plate by pulling out the tray. After the extension plate is fully pulled out, the handle connected to the tray is pulled out again. At this time, the locking pin connected to the tray will leave the inside of the slot, allowing the sliding pin connected to the tray to slide inside the extension plate to extend the length. This completes the operation, improves work efficiency, and relaxes the leg muscles that have been under pressure for a long time, thus reducing muscle strain.

[0025] In summary, this utility model has the advantages of storing important small items while relaxing leg muscles during office work. Attached Figure Description

[0034] Example 1

[0035] Reference Figures 1 to 3This utility model provides an embodiment of an office chair for preventing fatigue and reducing muscle strain, comprising a base 1. The base 1 serves as the supporting foundation for the entire office chair, bearing the user's weight and ensuring stable use. An armrest 2 is fixedly connected to the outside of the base 1. The armrest 2 not only provides support for the user's arms but also has a storage function, convenient for storing frequently used small items. A button 3 is slidably connected to the inner wall of the armrest 2. The button 3 is the key operating component for activating the storage function of the armrest 2; pressing it triggers the storage action. A slide plate 4 is fixedly connected to the outside of the button 3. The slide plate 4 transmits the pressure applied by the button 3 to a slider 5. A slider 5 is fixedly connected to the end of the slide plate 4 away from the button 3. The slider 5 moves under the push of the slide plate 4, thereby driving the connected slide plate 4 to operate in coordination.

[0036] A sliding sleeve 6 is slidably connected to the end of slider 5 away from slide plate 4. Sliding sleeve 6 provides guidance and limit for the movement of slider 5, ensuring that slider 5 moves along a predetermined trajectory. Two springs 7 are fixedly connected to the outside of sliding sleeve 6. Springs 7 can store elastic potential energy when compressed by external force and can release the potential energy to return to their original state after the external force disappears, playing a role in buffering and resetting. A locking block 8 is fixedly connected to the end of sliding sleeve 6 away from the two springs 7. Locking block 8 cooperates with locking plate 13 to lock and unlock cover plate 12, controlling the opening and closing state of the handrail 2. A top block 9 is slidably connected to the inner wall of handrail 2. Top block 9 can move under the action of sliding sleeve 6, thereby affecting the state between locking block 8 and locking plate 13. A limiting plate 10 is fixedly connected to the outside of top block 9. Limiting plate 10 restricts the movement range of top block 9, allowing it to move accurately within a specified range.

[0037] A spring 11 is fixedly connected to the end of the limiting plate 10 away from the top block 9. Spring 11 can also store and release elastic potential energy, changing its state according to the engagement of the locking block 8 and the locking plate 13, thus affecting the operation of the entire structure. A cover plate 12 is rotatably connected to the outside of the handrail 2. The cover plate 12 rotates around the connection point, closing and opening the internal space of the handrail 2, serving to protect and store items. A locking plate 13 is fixedly connected to the outside of the cover plate 12. The locking plate 13 engages with the locking block 8, which is a key structure for keeping the cover plate 12 in the closed state. A pull plate 14 is fixedly connected to the outside of the cover plate 12. The pull plate 14 allows the user to easily grip and pull, thereby rotating and opening the cover plate 12.

[0038] Example 2

[0039] Reference Figure 1 and Figure 4The base 1 has a fixed external connection to a storage plate 15, which is used to store and support the extension plate 16, providing a space for the leg support components. The storage plate 15 is fixedly connected to the outside of the base 1, ensuring it can be stably installed on the office chair. The extension plate 16 is slidably connected to the inner wall of the storage plate 15, sliding in and out within it to adjust the length of the leg support according to the user's needs. The extension plate 16 has a slot 17 on its outer surface, which cooperates with a locking post 20 to restrict the position of the support plate 18, achieving a locking function for different length adjustments. The support plate 18 is slidably connected to the inner wall of the extension plate 16, sliding within it to further change the length of the leg support to meet the needs of different users. The support plate 18 is fixedly connected to the outside of a sliding post 19, which provides guidance and limits for the sliding of the support plate 18 within the extension plate 16, ensuring smooth and stable sliding. The inner wall of the tray 18 is fixedly connected with a locking post 20, which can engage or disengage with the locking groove 17 to control the position of the tray 18 and the overall length of the extension plate 16.

[0040] Reference Figures 2 to 3 The outer sliding plate 4 is slidably connected to the inner wall of the handrail 2. The sliding plate 4 slides along the inner wall of the handrail 2, ensuring that it stably and accurately transmits force to the slider 5 when pressure is applied by the button 3. The outer sliding plate 5 is also slidably connected to the inner wall of the handrail 2. The slider 5 slides within the constraint of the inner wall of the handrail 2, preventing deviation and other abnormalities, making the entire transmission process more reliable. The outer sliding plate 6 is also slidably connected to the inner wall of the handrail 2. The sliding plate 6 slides within the constraint of the inner wall of the handrail 2, allowing it to move the locking block 8 more precisely, ensuring accurate engagement with its locking plate 13. The end of the spring 7 furthest from the sliding plate 6 is fixedly connected to the inner wall of the handrail 2. This connection method provides a stable point of force when the spring 7 is compressed and released, better fulfilling its buffering and restoring functions. The outer sliding plate 8 is also slidably connected to the inner wall of the handrail 2. The locking block 8 slides within the inner wall of the handrail 2, facilitating engagement or disengagement with the locking plate 13, thus controlling the opening and closing state of the cover plate 12. The limiting plate 10 is externally slidably connected to the inner wall of the handrail 2. The limiting plate 10 slides on the inner wall of the handrail 2, which can ensure that it moves with the top block 9 within a reasonable range.

[0041] One end of spring 11, away from the limiting plate 10, is fixedly connected to the inner wall of the handrail 2. This allows spring 11 to stably store and release elastic potential energy, pushing the top block 9 according to the state changes of the locking block 8 and the locking plate 13. The external part of the locking block 8 is movably connected to the outside of the locking plate 13. This movable connection enables the locking and unlocking functions. When locked, it keeps the cover plate 12 closed; when unlocked, it opens the cover plate 12, facilitating operation inside the handrail 2. The end of the top block 9, away from the limiting plate 10, contacts the outside of the locking block 8. Through this contact, the top block 9, under the action of relevant elastic components, applies a pushing or pulling force to the locking block 8, affecting the locking state of the locking block 8 and the locking plate 13. The external part of the locking plate 13 is slidably connected to the inner wall of the handrail 2. The locking plate 13 slides on the inner wall of the handrail 2, ensuring smooth locking and unlocking operations with the locking block 8 and maintaining the normal switching of the opening and closing state of the cover plate 12.

[0042] Reference Figure 1 and Figure 4 The sliding column 19 is externally slidably connected to the inner wall of the extension plate 16. The sliding column 19 slides along the inner wall of the extension plate 16, making the sliding of the support plate 18 within the extension plate 16 smoother and more stable, ensuring convenient operation for adjusting the leg support length. The locking column 20 is externally movably connected to the inner wall of the locking groove 17. This movable connection between the locking column 20 and the locking groove 17 allows for effective locking and unlocking of the support plate 18, facilitating adjustment of the leg support length as needed. The outer surface of the locking column 20 contacts the inner wall of the extension plate 16. Through this contact, the engagement and disengagement of the locking column 20 within the locking groove 17 allows for more precise control of the length of the support plate 18 and the entire leg support component, improving reliability and convenience of use.

[0043] Work steps

[0044] Step 1: During use, by pressing the button 3 connected to the armrest 2 above the base 1, the button 3 applies pressure to the slider 5 through the slide plate 4, causing the slider 5 to move inside the sliding sleeve 6. Since the contact surface between the slider 5 and the sliding sleeve 6 is a symmetrical slope, the lateral force is converted into a longitudinal force. Therefore, the sliding sleeve 6 will move the locking block 8 towards the spring 7 and squeeze the spring 7. At this time, the spring 7 will compress the space, allowing the locking block 8 enough space to leave the locking plate 13 and no longer engage. The spring 11 connected inside the armrest 2 releases potential energy to the top block 9 through the limiting plate 10 because the locking plate 13 and the locking block 8 are no longer engaged. This causes the locking plate 13 to move above the locking block 8. Then, by pulling the pull plate 14 connected to the cover plate 12, the entire cover plate 12 can be moved away from the armrest 2 and no longer close. Items can then be placed inside the armrest 2 for storage, improving the utilization rate of the office chair and facilitating the quick storage of items.

[0045] Step 2: When the legs need to relax, pull out the handle connected to the inner tray 18 of the storage plate 15 under the base 1. Then pull out the inner extension plate 16 of the storage plate 15 by pulling out the tray 18. After the extension plate 16 is fully pulled out, continue to pull out by lifting the handle connected to the tray 18. At this time, the locking pin 20 connected to the tray 18 will leave the inside of the locking slot 17, allowing the sliding pin 19 connected to the tray 18 to slide inside the extension plate 16 to extend its length. This completes the operation, improving work efficiency while relaxing the leg muscles that have been under pressure for a long time and reducing muscle strain.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
