Abstract

The invention discloses an automatic fixing seat. The automatic fixing seat comprises a seat body, seat legs connected to the lower portion of the seat body, seat rolling wheels and locking devices connected to be lower portions of the seat legs and used for fixing the seat rolling wheels. Each locking device comprises a connecting block, a locking block fixed under the connecting block and guide rods fixedly connected with the two sides of the lower portion of the connecting block, and the guide rods are sleeved with reset springs. According to the automatic fixing seat, the seat rolling wheels are fixedly locked according to the weight of a human, only the empty seat can be slid, sliding is smooth and noiseless, it is avoided that when an existing rotary movable seat is used, people will often move the seat in a sitting mode for convenience, the seat is pressed accordingly, and noise is generated during friction movement on the ground and influences working and studying of other people; the locking devices of the whole seat legs are simple in structure, suitable in cost and quite suitable for occasions, such as libraries, where a large number of seats and the quiet environment are required at the same time.

Description

Automatically fixing seat

Technical field

The present invention relates to seat, particularly one fixes seat automatically.

Background technology

People often need a relatively quiet environment (as classroom in work or study, library, office and laboratory) just can concentrate one's energy to improve working and learning efficiency, and the existing seat not with roller can send the very large ear-piercing sound with ground friction when mobile, the normal study having had a strong impact on other staff is had a rest, existing office revolving chair special is designed to still can move when people is sitting on chair, and because people's own body weight is to the pressure of chair, when being seated mobile, chair roller and earth surface still can send the larger sound, add that it can realize, the several functions such as rotation and lifting, therefore complex structure, price is also high, if existing rotational slide seat is bought in the place of a large amount of seat of this needs in library, cost is too high and can not fundamentally solve the problem sending the sound when chair moves.

Summary of the invention

Task of the present invention is to provide one and can only slides by empty chair, and mobile smooth and easy noiseless and automatically fix, structure is simple, and moderate cost is highly suitable for the automatically fixing seat in library to solve the deficiencies in the prior art.

The present invention is achieved through the following technical solutions goal of the invention:

A kind of fixing seat automatically, comprise seat body, be connected to seat body under seat leg, seat roller and the locking system that is connected to for fixing seat roller below seat leg, the guide post that described locking system comprises contiguous block, is fixed on the latch immediately below described contiguous block and is fixedly connected with both sides below contiguous block.

Further, back-moving spring is arranged with outside described guide post, guide post is made up of fixed bar and the piston rod be fixed on described fixed bar and cylinder barrel, the top of described cylinder barrel is fixed on contiguous block, the bottom of described fixed bar is fixedly connected with a transverse axis, described transverse axis is by the center of circle of described seat roller, thus, when people sits on the seat, the while that cylinder barrel moving down along piston rod, latch moves down and blocks seat roller, transverse axis blocks seat roller and realizes the automatically fixing of seat thus from left and right, when people stands up to leave seat, latch and contiguous block top are returned original position along the reseting elasticity of guide rod by back-moving spring, seat roller unlocks.

Further, described latch is be positioned at one piece of cork block directly over seat roller or two pieces of vertical baffles for being positioned at both sides before and after below contiguous block, thus, when people sits down, cork block can from blocking seat roller up and down, and use vertical baffle can block seat roller from front and back.

Further, described latch is two arc-shaped slots being positioned at both sides before and after below contiguous block, inner surface and the seat roller of draw-in groove are suitable, thus, people's two draw-in grooves of sitting down simultaneously can block seat roller from upper and lower and front and back, add transverse axis from left and right restriction seat roller, more stable when people is sat on the seat.

Further, the top of described cylinder barrel is fixed on contiguous block by an adjustment block, and adjustment block and described contiguous block are rotationally connected.Thus, the relative position of cylinder barrel and fixed bar can be regulated by rotating adjustment soon, thus meet different load-bearing requirements.

Further, described cylinder barrel bottom is not less than described latch to the distance on fixed bar top and moves down the distance blocking described seat roller, thus, can block seat roller from top to bottom to greatest extent when people is sitting on chair.

Further, described contiguous block is connected with described seat leg by a rotating shaft, and thus, described seat roller can move along any direction.

Further, outside described back-moving spring, be arranged with rubber cover, thus, the service life of back-moving spring can be extended.

Automatically fixing seat provided by the invention has the following advantages:

1, the body weight of people self is relied on to be fixed locking to seat roller, therefore can only slide by empty chair, mobile smooth and easy have no the sound, avoid occurring using existing seat in rotary moving, move in ground friction because being stressed because people can scheme the convenient moved seat that often can be seated and send the sound and affect other people work and study;

2, after user sits down, locking system can to seat roller simultaneously from up and down, and left and right and front and back are fixed, and makes that seat is highly stable not easily arbitrarily to slide;

3, the locking system structure of whole seat leg is simple, cost-effective, but is highly suitable for the occasion that a large amount of seats of needs such as library require environment quiet.

Detailed description of the invention

Below in conjunction with accompanying drawing, embodiments of the present invention are described in further detail.

Embodiment 1

As shown in Figure 1 to Figure 2, a kind of fixing seat automatically, comprise seat body (not shown), be connected to seat body under seat leg 1, seat roller 2 and the locking system 3 that is connected to for fixing seat roller 2 below seat leg, the guide post that locking system 3 comprises contiguous block 31, is fixed on the latch immediately below contiguous block 31 and is fixedly connected with both sides below contiguous block 31.

Wherein, back-moving spring 32 is arranged with outside guide post; rubber cover is arranged with outside back-moving spring 32; guide post is made up of fixed bar 35 and the piston rod 33 be fixed on fixed bar 35 and cylinder barrel 34; the top of cylinder barrel 33 is fixed on contiguous block 31; the bottom of fixed bar 35 is fixedly connected with a transverse axis 4, and transverse axis 4 is by the center of circle of seat roller 2, and contiguous block 31 connects to make seat roller 2 can any movement as universal wheel by rotating shaft 8 and seat leg 1.

Latch is the one piece of cork block 5 be positioned at directly over seat roller, and latch also can be two pieces of both sides before and after being positioned at below contiguous block vertically hard baffle plate (not shown).

The top of cylinder barrel is fixed on contiguous block by an adjustment block 7, cylinder barrel 34 bottom equals cork block 5 to the distance on fixed bar 35 top and moves down the distance blocking seat roller 2, in order to from top to bottom block seat roller 2 to greatest extent, cylinder barrel 34 bottom also can be greater than cork block 5 to the distance on fixed bar 45 top and move down the distance blocking seat roller 2.
