Description

Technical Field

[0001] The invention relates to the technical field of bar chairs, in particular to a bar chair which can be automatically adjusted according to human body posture. Background Art

[0002] Existing bar chairs can only adjust the height of the seating area. Generally, in order to adapt to the height of the bar counter, the bar chair is relatively slender and high. In order to better support the feet and avoid the feet leaving the ground and causing discomfort without a support point, the bar chair is generally equipped with a footrest. However, the height of the footrest is generally not adjustable, so people with different leg lengths cannot make adaptive adjustments when sitting.

[0003] This case is proposed in order to improve and optimize the above-mentioned problems or shortcomings. Summary of the invention

[0004] A bar chair capable of automatically adjusting according to human body posture, comprising a bar chair base, a bar chair support rod fixed on the bar chair base, and a bar chair stool fixed on the bar chair support rod;

[0005] A pedal is provided on the outside of the bar chair support rod for sliding up and down installation, and an adjusting structure is provided at the bottom of the bar chair seat to adjust the height position of the pedal.

[0006] Preferably, the adjustment structure includes a motor fixed to the bottom of the bar chair seat and an adjustment screw driven by the motor, wherein the adjustment screw is parallel to the axis of the bar chair support rod, and also includes a controller, which controls the forward and reverse rotation of the motor.

[0007] Preferably, a support plate is fixed on the pedal, a dustproof self-lubricating adjustment nut is fixed on the support plate, the adjusting screw and the dustproof self-lubricating adjustment nut form a spiral pair, and after the adjusting screw rotates, the pedal is driven to move up and down along the axis of the bar chair support rod through the spiral pair.

[0008] Preferably, a travel limit nut is threadedly connected to the lower end of the adjusting screw, and the upper end of the travel limit nut abuts against the lower end of the dustproof self-lubricating adjusting nut to limit the further downward movement of the dustproof self-lubricating adjusting nut.

[0009] Preferably, the dustproof self-lubricating adjusting nut is provided with threads inside and dustproof rubber rings are provided at the upper and lower ends of the inner hole of the dustproof self-lubricating adjusting nut.

[0010] Preferably, a sponge ring is embedded in the dustproof self-lubricating adjusting nut, and the sponge ring is soaked with silicone-based grease. The inner wall of the sponge ring is against the outer wall of the adjusting screw, and then the sponge ring is squeezed during the movement and coordination of the spiral pair to cause it to partially deform and allow the silicone-based grease to overflow for lubrication.

[0011] The advantages and positive effects of the present invention are:

[0012] 1. The pedal in the present application can be adjusted in height through the drive of the spiral pair to facilitate appropriate stepping and be more comfortable.

[0013] 2. The adjustment structure is sealed and dustproof and the built-in lubrication part can maintain long-term good and smooth sliding adjustment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0019] If there are terms involving directional indications or positional relationships in the embodiments of the present application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings); if the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, the terms "first", "second", etc. involved in the embodiments of the present application are only used for the purpose of convenience of description and cannot be understood as indicating or implying relative importance.

[0020] The embodiments of the present invention are further described in detail below with reference to the accompanying drawings:

[0021] like Figure 1-2 As shown, the bar chair capable of automatically adjusting according to the human body posture described in the present invention comprises a bar chair base 18, a bar chair support rod 12 fixed on the bar chair base 18, and a bar chair stool 10 fixed on the bar chair support rod 12;

[0022] A pedal 13 is provided on the outside of the bar chair support rod 12 for sliding up and down, and an adjustment structure is provided at the bottom of the bar chair seat 10 to adjust the height position of the pedal 13 .

[0023] Preferably, the adjustment structure includes a motor fixed at the bottom of the bar chair seat 10 and an adjustment screw 14 driven by the motor, wherein the adjustment screw 14 is parallel to the axis of the bar chair support rod 12, and also includes a controller 11, wherein the controller 11 controls the forward and reverse rotation of the motor.

[0024] Preferably, a support plate 15 is fixedly provided on the pedal 13, and a dustproof self-lubricating adjustment nut 16 is fixedly provided on the support plate 15. The adjusting screw 14 and the dustproof self-lubricating adjustment nut 16 form a spiral pair. After the adjusting screw 14 rotates, the pedal 13 is driven to move up and down along the axis of the bar chair support rod 12 through the spiral pair.

[0025] Preferably, a travel limit nut 17 is threadedly connected to the lower end of the adjusting screw 14, and the upper end of the travel limit nut 17 abuts against the lower end of the dustproof self-lubricating adjusting nut 16 to limit the further downward movement of the dustproof self-lubricating adjusting nut 16.

[0026] Preferably, the dustproof self-lubricating adjusting nut 16 is provided with threads inside and dustproof rubber rings 20 are provided at the upper and lower ends of the inner hole of the dustproof self-lubricating adjusting nut 16 .

[0027] Preferably, a sponge ring 19 is embedded in the dustproof self-lubricating adjusting nut 16, and the sponge ring 19 is soaked with silicone-based grease. The inner wall of the sponge ring 19 abuts against the outer wall of the adjusting screw 14, and then the sponge ring 19 is squeezed during the movement and coordination of the spiral pair to partially deform it, thereby allowing the silicone-based grease to overflow for lubrication.

[0028] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive, and therefore the present invention is not limited to the embodiments described in the specific implementation manners. Any other implementation manners derived by those skilled in the art based on the technical solutions of the present invention also fall within the scope of protection of the present invention.
