Description

Technical Field

[0001] The utility model particularly relates to an office chair with stable suspension. Background Art

[0002] Office chairs are seats designed for office spaces to provide comfortable sitting and support users in maintaining correct posture while working.

[0003] Existing office chairs mostly use the elasticity of the backrest to support the user. The elasticity is mostly due to the curved surface of the backrest, which supports the user's back when leaning back through its own deformation. However, the elasticity of the backrest itself is limited. The instantaneous impact force when the user just contacts the backrest cannot be well buffered, and the comfort effect is not good. The impact force on the user's back is large. For this reason, we propose an office chair with stable suspension. Utility Model Content

[0004] The purpose of the utility model is to provide an office chair with stable suspension to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: an office chair with stable suspension, comprising:

[0006] A bracket, the bracket being detachably connected to a base, and the base being provided with a cushion;

[0007] A connecting frame, both ends of which are respectively fixed to the side walls of the base, and a backrest is connected to the upper surface of the connecting frame;

[0008] The suspension component is detachably installed between the connecting frame and the base, so as to provide elastic buffering through the suspension component when leaning against the backrest.

[0009] Preferably, the suspension assembly includes a connecting sleeve, a mounting block, a telescopic rod and a spring. The mounting block is fixed to one end of the lower surface of the base, the telescopic rod is fixed to the connecting frame through the connecting sleeve at one end thereof, and the other end of the telescopic rod is slidably matched with the mounting block, and a spring is provided on the inner side of the mounting block for elastically supporting the telescopic rod.

[0010] Preferably, the telescopic rod is cylindrical, and the other end of the telescopic rod protrudes outward to form an anti-dropping protrusion.

[0011] Preferably, the connecting frame is arc-shaped.

[0012] Preferably, lifting rods are provided on the upper surfaces of both ends of the connecting frame, handrail blocks are provided on the lifting rods, and buttons for controlling the lifting and lowering of the lifting rods are installed on the lower surfaces of the handrail blocks.

[0013] Preferably, a universal wheel is detachably connected to the lower surface of the bracket, and a plurality of the universal wheels are provided.

[0014] Preferably, a headrest is provided at the top end of the backrest.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The utility model adds suspension technology on the basis of the original leisure office chair by providing a connecting sleeve, a mounting block, a telescopic rod and a spring, so as to provide stable support for the user and avoid a large impact on the body when leaning back, so as to provide stable support and reduce the pressure on the spine, reduce fatigue, make people very comfortable in use, have a good user experience, meet safety standards, and under normal use conditions, the user will not suffer accidental injuries, thereby improving the safety of the chair.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 4 The utility model provides a technical solution: a stable hanging office chair, comprising:

[0024] A bracket 1, to which a base 2 is detachably connected, and a cushion 3 is provided on the base 2;

[0025] A connecting frame 5, both ends of which are fixed to the side walls of the base 2, and a backrest 4 is connected to the upper surface of the connecting frame 5 to support the user when leaning back;

[0026] The suspension component can be detachably installed between the connecting frame 5 and the base 2, so that elastic buffering can be performed through the suspension component when leaning against the backrest 4, so as to efficiently buffer the impact force at the moment of contact with the backrest 4 when leaning back, so as to provide stable support and reduce spinal pressure.

[0027] In this embodiment, preferably, the suspension assembly includes a connecting sleeve 12, a mounting block 9, a telescopic rod 10 and a spring 11. The mounting block 9 is fixed to one end of the lower surface of the base 2. The telescopic rod 10 is fixed to the connecting frame 5 through the connecting sleeve 12 at one end thereof for easy connection and fixation. The material of the connecting frame 5 is preferably plastic, and the other end of the telescopic rod 10 is slidably matched with the mounting block 9. A spring 11 is provided on the inner side of the mounting block 9 for elastically supporting the telescopic rod 10 for better cushioning effect.

[0028] In this embodiment, preferably, the telescopic rod 10 is cylindrical, and the other end of the telescopic rod 10 protrudes outward to form an anti-dropping protrusion.

[0029] In this embodiment, preferably, the connecting frame 5 is arc-shaped to facilitate a certain elastic deformation to provide an elastic buffering effect.

[0030] In this embodiment, preferably, lifting rods 7 are provided on the upper surfaces of both ends of the connecting frame 5, armrest blocks 8 are provided on the lifting rods 7, and buttons for controlling the lifting of the lifting rods 7 are installed on the lower surfaces of the armrest blocks 8 to better support the arms.

[0031] In this embodiment, preferably, the lower surface of the bracket 1 is detachably connected with a universal wheel 6, and a plurality of universal wheels 6 are provided for easy movement.

[0032] In this embodiment, preferably, a headrest is provided at the top of the backrest 4 to facilitate supporting the head.

[0033] The working principle and use process of the utility model: when in use, the angle between the base 2 and the backrest 4 is 110°, which meets the requirements of ergonomics. The backboard conforms to the natural curve of the human body, provides the user with good waist and back support, and helps to maintain a correct sitting posture. When the user leans back on the backrest 4, the force acts on the backrest 4. Through the arc-shaped design of the backrest 4 and the connecting frame 5, the first buffering can be performed. At the same time, when leaning back, the telescopic rod 10 will be pushed to move toward the inside of the mounting block 9, squeezing the spring 11, and then the second buffering is performed through the reverse elastic force of the spring 11, so as to absorb the forces in different directions generated by the user when leaning back for many times.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
