Embodiment Construction
[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0021] see Figure 1-5 , an air pressure bar for an ergonomic seat, comprising an outer sleeve 1, an inner sleeve 2 is movably sleeved inside the outer sleeve 1, an inner shell core 3 is fixedly sleeved inside the inner sleeve 2, and the inner shell core The explosion-proof layer 4 is fixedly installed on the inner side of the explosion-proof layer 4, and the upper and lower ends of the inner side of the explosion-proof layer 4 are fixedly installed with press...

The invention relates to the technical field of articles of daily use, and discloses an air pressure rod for an ergonomic seat, the air pressure rod comprises an outer sleeve, an inner sleeve is movably sleeved with the outer sleeve, an inner shell core is fixedly sleeved with the inner sleeve, and an explosion-proof layer is fixedly mounted on the inner side of the inner shell core. By arranging the first buffer bag and the second buffer bag, the problem that the bottom end of the inner sleeve is damaged due to the fact that the inner sleeve collides with the fixing block when falling rapidly is effectively avoided, and by arranging the anti-explosion layer, the pressure measuring ventilation opening, the piston rod and the pressure resisting bag, the air pressure intensity in the upper air chamber is effectively relieved, and the safety of the device is improved. The gas pressure borne by the surface of the inner wall of the anti-explosion layer is relieved, the problem that the pipe wall cannot bear the gas pressure and bursts is solved, a warning hammer is arranged so that a user can be informed that the seat is overloaded, potential safety hazards can be caused, the user is reminded to reduce the weight or sit lightly, and therefore the safety of the user is guaranteed, and meanwhile the safety of the user is improved. And the usability of the seat is also protected.
Description
technical field [0001] The invention relates to the technical field of daily necessities, in particular to an air pressure rod for an ergonomic seat. Background technique [0002] Ergonomic seat is a kind of seat cushion and chair back made of elastic and environmentally friendly materials such as mesh cloth, environmental protection cloth and high-quality memory foam. The height-adjustable function of the chair is generally realized by a pneumatic rod, and the pneumatic rod is generally composed of a hollow tubular outer cylinder, a hollow tubular inner cylinder, a piston, a piston rod, and an adjustment switch. Changes in the flow of gas in the middle, and then achieve the effect of adjusting the height. [0003] When the user adjusts the height of the seat with the air rod and starts to sit down, the sleeve receives a downward force, the upper air chamber of the air rod is compressed, and the gas inside exerts a huge pressure on the piston and the tube wall. When it is ...
