Abstract

The utility model provides an office chair base plate, which relates to a connecting plate between an office chair seat plate and an air pressure rod, in particular to a connecting plate control mechanism arranged between the office chair seat plate and the air pressure rod. The office chair base plate comprises a base plate seat (1) and a fixed seat (2), wherein the fixed seat (2) is hinged onto the base plate seat (1) through a shaft (3), and an air pressure rod fixing hole (21) is arranged on the fixed seat (2). The office chair base plate is characterized in that a fixed pin device (4) is arranged on the fixed seat (2), and a pin hole (5) is arranged on the base plate seat (1) and corresponds to the fixed pin device (4). In the structure, the control for an included angle between the base plate seat and the fixed seat is realized through spring pins, the stability of the chair is enhanced, the safety performance is high, the use is safer, and the quality is assured. The spring pins are controlled through a wire pulling handle to operate and control the fixed seat, the structure is simple, and the use is very convenient.

Description

The office chair chassis

Technical field

The utility model office chair chassis relates to the terminal pad between office chair seat board and the air pressure rod, especially the terminal pad controlling organization between office chair seat board and the air pressure rod.

Background technology

Existing office chair chassis mainly comprises subbase and is articulated in holder on the subbase have the air pressure rod fixing hole to be used to install air pressure rod on the described holder, also has the reclining adjusting device; This reclining adjusting device comprises bolt knob, compression spring.Adjust the angle of subbase and holder by the turn bolt, realize the gradient of office chair seat plate.There is a defective in this structure, because subbase and holder are articulated and connected, the magnitude of inclination of its office chair seat plate is limited by the elastic force of the compression spring on the bolt, and the angle of subbase and holder changes, its steadiness is relatively poor relatively, the phenomenon that chair can occur waving.

Summary of the invention

The purpose of this utility model provides a kind of new office chair chassis, by the angle between spring catch fixed underpan seat and the holder, strengthens the steadiness of seat, and simple in structure, the user uses safer, and is more relieved.And control more convenient.

The utility model office chair chassis, comprise subbase 1 and be articulated in holder 2 on the subbase 1 by axle 3, on the described holder 2 air pressure rod fixing hole 21 is arranged, it is characterized in that on the described holder 2 fixed pin arrangement 4 being installed, relative with described fixed pin arrangement 4 on subbase 1 should have pin-and-hole 5.

Above-mentioned office chair chassis, described pin-and-hole 5 have one to four.

Above-mentioned office chair chassis, described fixed pin arrangement 4 comprises spring pin 41 and spanner 42.

Above-mentioned office chair chassis, described spanner 42 is the backguy handle.

Above-mentioned office chair chassis, described fixed pin arrangement 4 is positioned at the end of described holder 2.

There is "T"-shaped lever 6 on above-mentioned office chair chassis on the described holder 2, this "T"-shaped lever 6 is positioned at air pressure rod fixing hole 21 places, and the described "T"-shaped lever 6 of backguy handle 61 controls is arranged.

Adopt above-mentioned office chair chassis,, strengthen the steadiness of seat by the angle between spring pin realization control subbase and the holder, the security performance height, the user uses safer, and is more relieved., simple in structure by backguy handle control spring pin to control holder, use more convenient.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

See Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model office chair chassis comprises subbase 1 and is articulated in holder 2 on the subbase 1 by axle 3, on the described holder 2 air pressure rod fixing hole 21 is arranged, on this holder 2, also have reclining adjusting device 22, see shown in Figure 1.On described holder 2 fixed pin arrangement 4 is installed, relative with described fixed pin arrangement 4 on subbase 1 should have pin-and-hole 5, sees Fig. 2, shown in Figure 3; Described fixed pin arrangement 4 comprises spring pin 41 and spanner 42, and described spanner 42 is for being illustrated as the backguy handle, and so the end user controls convenient; Can certainly be other form spanners.When twisting the backguy handle as shown in Figure 3, in the spring pin 41 retraction holders 2, this moment is by adjusting turn reclining adjusting device 22, make the holder 2 and the angle of subbase 1 change, see Fig. 4, shown in Figure 5, when finding suitable reclining angle, loosening backguy handle, spring pin 41 inserts pin-and-hole 5, so the fixed angle of holder 2 and subbase 1.

Further form, described fixed pin arrangement 4 is positioned at the end of described holder 2, especially is positioned at the relative end of reclining adjusting device 22, so can adapt to the big adjustment of angle of holder 2 and subbase 1.

For further facilitating the user, "T"-shaped lever 6 is arranged on described holder 2, and this "T"-shaped lever 6 is positioned at air pressure rod fixing hole 21 places, and the bottom of described "T"-shaped lever 6 and the air tube of air pressure rod join, the described "T"-shaped lever 6 of backguy handle 61 controls is arranged, see shown in Figure 6.When twisting backguy handle 61, the bottom of "T"-shaped lever 6 presses down the air tube of air pressure rod, the height that this moment just can seat.
