TECHNICAL FIELD
[0001] The present application relates to the technical field of office chairs, and particularly relates to an office chair with a standing function. BACKGROUND
[0002] With the development of the times, daily long-time sitting has become a common phenomenon among the working population. According to a report of the World Health Organization, only 7 countries in the world have a sitting level lower than 10%, and 1.4 billion people are at risk of illness due to lack of exercise, and "sitting" is listed as one of the top ten death-causing culprits and one of the four major non-communicable diseases. According to research, after the subjects sat for 30 minutes, some simple activities such as walking and doing housework can reduce the risk of cancer death by 31%, so it can be seen that frequent posture adjustment during work is beneficial to alleviate the harm caused by sitting.
[0003] At present, there are also some office chairs that can be used in sitting and standing on the market. Such office chairs can switch the seat plate from a horizontal (or nearly horizontal) state to a standing state (parallel or attached to the backrest) through the cooperation of a slide, a lock hook and an extension frame, so as to realize the conversion from a sitting posture to a standing posture. Although this type of seat that can be used in sitting and standing can solve the problem of long-time sitting, the switching structure of the seat plate is relatively complex, which leads to a relatively complex and bulky overall structure of the office chair, and the selling price is also relatively high compared with ordinary office chairs.
[0004] The technical problem to be solved by the present application is how to solve the problems of complex structure and high price of existing office chairs that can be used in sitting and standing. SUMMARY
[0005] In order to overcome the shortcomings of the prior art, the purpose of the present application is to provide an office chair with a standing function, which can change an ordinary office chair into an office chair that can be used in sitting and standing by adding a standing mechanism to the existing office chair, and has the characteristics of simple structure and low cost.

[0065] In other embodiments, the moving member 24 can be arranged as a structure similar to a seesaw, that is, two oppositely arranged plate structures are arranged, and then the two moving members 24 are connected by a connecting rod, and the middle part of the connecting rod is hinged to the pedal 21, so that the two moving members 24 can be linked, and left and right shaking can be realized when two feet are stepped on the two moving members 24. In other embodiments, the moving member 24 can also be arranged as a plate structure, and a shaft is arranged at the middle part of the side surface of the moving member 24, and the shaft is hinged to the pedal 21, so that the moving member 24 can be shaken forward and backward when a foot is stepped on the moving member 24.
[0066] In one embodiment, the standing mechanism 20 further includes a locking assembly 25 for restricting the movement of the moving member 24 relative to the pedal 21. When relaxation is not required, the moving member 24 can be locked by the locking assembly 25 to prevent the moving member 24 from interfering with standing.
[0067] like Figures 5 to 11 As shown, in this embodiment, the locking assembly 25 includes a trigger key 251, a transmission rod 252, and a locking hook 253. The trigger key 251 is movably connected to the pedal 21, and the locking hook 253 is pivotally connected to the pedal 21. One end of the transmission rod 252 is connected to the trigger key 251, and the other end abuts against the locking hook 253. The moving component 24 is provided with a locking groove corresponding to the locking hook 253. A second reset component 254 is provided between the locking hook 253 and the pedal 21. The second reset component 254 drives the locking hook 253 to remain abutting against the transmission rod 252. When the trigger key 251 is subjected to external force, it drives the locking hook 253 to rotate through the transmission rod 252, causing the locking hook 253 to engage or disengage from the locking groove. When pedaling is required, the trigger key 251 can be driven to disengage the locking hook 253 from the locking groove, and the moving component 24 can move according to the user's foot pedaling motion. When pedaling is not required, the trigger key 251 is driven to engage the locking hook 253 with the locking groove, restricting the movement of the moving component 24.
[0068] Furthermore, the locking hook 253 includes a locking tongue 2531, a rotating shaft 2532, and an abutment post 2533. The locking tongue 2531 corresponds to the locking groove on the moving part 24. One end of the rotating shaft 2532 is fixedly connected, and the other end is rotatably engaged with the pedal 21. The abutment post 2533 is fixedly connected to the locking tongue 2531. The trigger drives the transmission rod 252 to move back and forth in a straight line. The trigger is provided with a first abutment surface 2521 and a second abutment surface 2522 that abut against the side of the abutment post 2533. The first abutment surface 2521 is parallel to the moving direction of the transmission rod 252, and the second abutment surface 2522 is set at an angle to the moving direction of the transmission rod 252. When the abutment post 2533 abuts against the first abutment surface 2521, the locking tongue 2531 engages with the locking groove. When the abutment post 2533 abuts against the second abutment surface 2522, the locking tongue 2531 separates from the locking groove.
[0069] In the embodiment, the trigger key 251 comprises a key cap 251a, an extension column 251b, a rotating column 251c, a barrel 251d and a pressing block 251e. The key cap 251a is in sliding fit with the top cover, and the key cap 251a is connected with the top of the extension column 251b. A plurality of first protrusions 251h are arranged at the bottom of the extension column 251b in a circumferential direction. The rotating column 251c is in rotating fit with the inner hole of the extension column 251b, and a plurality of second protrusions 251i are arranged at the bottom of the rotating column 251c in a circumferential direction. The number of the second protrusions 251i is less than that of the first protrusions 251h, and the distance between adjacent two second protrusions 251i is greater than that between adjacent two first protrusions 251h. The extension column 251b and the rotating column 251c are arranged in the inner hole of the barrel 251d. The inner wall of the barrel 251d is alternately provided with first grooves 251j and second grooves 251k in a circumferential direction, wherein the depth of the first grooves 251j is greater than that of the second grooves 251k. The top of the pressing block 251e is in abutment with the rotating column 251c, and the bottom of the pressing block 251e is wedge-shaped. The end of the transmission rod 252 is provided with a slope matched with the pressing block 251e. The bottom of the pressing block 251e is further provided with a fourth reset member 251f for resetting.
[0070] Further, in order to facilitate the resetting of the transmission rod 252, a third reset member 255 is arranged between the transmission rod 252 and the bottom cover, and the third reset member 255 is used to drive the resetting of the transmission rod 252.
[0071] Preferably, in order to make the movement of the transmission rod 252 more accurate, a sliding groove 2523 is arranged on the transmission rod 252, and a limiting column matched with the sliding groove 2523 is arranged on the bottom cover.
[0072] The working principle of the trigger key 251 is as follows:
[0073] When the key cap 251a is pressed, the telescopic column 251b is driven to move downward, the bottom of the first protrusion 251h has a first slope, the top of the second protrusion 251i is provided with a second slope which is matched with the first slope, so that when the telescopic column 251b is pressed downward, the rotating column 251c is driven to move downward and rotate at the same time, the rotating column 251c drives the extrusion block 251e to move downward, so as to extrude and slide the transmission rod 252 in the horizontal direction, after the hand is released, because the second protrusion 251i is clamped in the second groove 251k, the rotating column 251c cannot be reset, so that the extrusion block 251e keeps extruding the transmission rod 252, thereby driving the lock hook 253 to rotate and be disengaged from the lock slot. When the key cap 251a is pressed again, the telescopic column 251b is lowered while driving the rotating column 251c to rotate, so that the second protrusion 251i is switched from the second groove 251k to the first groove 251j, when the hand is released, the rotating column 251c can be reset smoothly, the transmission rod 252 is also reset under the action of the third reset member 255, and the lock hook 253 is also reset, at this time, the lower pressing member 24 can make the lock hook 253 be buckled with the lock slot.
