Abstract

The utility model is a chair leg tube height regulator, comprising a housing, a pressing spring eccentric button, an eccentric gear, a pressing spring and an elastic pin. The housing is installed on the leg tube, the eccentric gear is embedded on the pressing spring eccentric button which is connected with the housing by an axial pin. When in use, the pressing spring eccentric button is pressed or released, making the eccentric gear and a telescopic tube to release and press, so the goal of regulating the height is reached. The utility model has the advantages of convenient operation and beautiful appearance. The utility model can be used for regulating the height for the leg tube of the chair or other furniture.

Description

Foot of chair pipe height adjuster

Technical field

The utility model relates to a kind of chair, the chair that especially a kind of Foot of chair pipe height can be regulated.

Background technology

The structure that at present common Foot of chair pipe height is regulated as shown in Figure 1, it by pin pipe 11, bullet pin 12, play pin-and-hole 13 and telescoping tube 14 is formed.With finger the bullet pin 12 on the Foot of chair pipe 11 is pressed in the bullet pin-and-hole 13 of pin pipe 11 during use, pulls moving telescoping tube 14 with another then, bullet pin 12 is sprung into to the hole of the telescoping tube 14 of desired height.The shortcoming of this adjusting device is: at first owing in the chair pin pipe outside a plurality of bullet pin-and-holes are arranged, influence the attractive in appearance of chair integral body; Secondly, must firmly the bullet pin be pressed in the bullet pin-and-hole, finger be had discomfort, even pain is arranged with finger; Have, the gap of 1 millimeter is arranged between telescoping tube and the pin pipe, this just makes chair that slight shaking and sound arranged in use.

Summary of the invention

The purpose of this utility model provides a kind of Foot of chair pipe height adjuster and solves chair height adjusting device numerous and diverse property, the unstability of structure and the problems such as aesthetic property of use in operation in the prior art.

Above-mentioned technical problem of the present utility model is to solve by following technical scheme.

The utility model is mounted on the pin pipe that is conditioned height, its locking state as shown in Figure 2, its relaxation state as shown in Figure 3, it is made up of shell 1, the eccentric button 2 of stage clip, eccentric gear 3, stage clip 4 and pivot pin 5, it is characterized in that eccentric gear 3 is embedded on the eccentric button 2 of stage clip, then eccentric button 2 usefulness the pivot pins 5 of stage clip are connected on shell 1, the protruding axle in location that stage clip 4 is placed on shell 1 go up and the compression spring hole of stage clip off-centre button 2 in.During use shell 1 of the present utility model is contained on the pin pipe 6 that is conditioned, when needs are regulated pin pipe height, press the eccentric button 2 of stage clip, eccentric gear 3 lifts and telescoping tube 7 disengages, can spur telescoping tube 7 to desired height, loosen the eccentric button 2 of stage clip then, under the elastic force of stage clip 4, eccentric gear 3 compresses telescoping tube 7, make it the location, reach the adjusting purpose.When chair was subjected to human body gravity, because the frictional force effect between telescoping tube 7 and the eccentric gear 3, eccentric gear 3 will upwards rotate, but because the employing eccentric structure, instead made it press tighter and tighter, thereby reached the locking purpose.When wanting to unclamp or readjust height, as long as press the eccentric button 2 of stage clip, at this moment, eccentric gear 3 leaves the gap that telescoping tube 7 has 1 millimeter, makes telescoping tube 7 capable of expansion and contraction.

The utlity model has easy to operate, handsome in appearance advantage, and because telescoping tube is pressed very tightly by eccentric gear, therefore sitting man-hour, pin Guan Buhui shakes, and also can not produce sound.The utility model can be used for the pin pipe of chair or the pin pipe height of other furniture is regulated.

The specific embodiment

Also in conjunction with the accompanying drawings the utility model is further specified below by embodiment.

Embodiment: pin pipe 6 adopts pipe aluminium alloy φ 25 * 1.2 among Fig. 2, and telescoping tube 7 adopts aluminium alloy φ 20 * 1.2.Shell 1 is made with mold injection as shown in Figure 4, is contained on the pin pipe 6 with the tight fit mode, and eccentric button 2 of stage clip and eccentric gear 3 are as shown in Figure 5.Eccentric gear 3 usefulness steel are cut into eccentric sector gear by line, its mould with the eccentric button 2 of stage clip is injected into a whole together, then stage clip 4 is put into that the protruding axle in the location of shell 1 is gone up and the compression spring hole of stage clip off-centre button 2 in, and the eccentric button 2 usefulness pivot pins 5 of stage clip are connected on the shell 1, as shown in Figure 2.

Claims
