Description
Technical field
The utility model relates to a kind of stool footmuff, is specifically related to a kind of presser sensor pulley stool footmuff.
Background technology
In Learning in School, or during office work, chair when people moves, can be driven to move.There is larger frictional force on common chair and ground, and therefore the mobile of chair always sends ear-piercing sound, extremely affects the mood of people.
And the chair on the market with pulley, although it has moveable function, people's instability when sitting down, the people of seat tilts a little, and chair just can move, and can not keep transfixion always, affects the use of people.
Utility model content
The technical problems to be solved in the utility model is: in order to solve the prior art Problems existing in above-mentioned background technology, provides one pulley regracting under a certain pressure, and pulley lockable, and the responsive pulley stool footmuff of adjustable chair height.
The utility model solves the technical scheme that its technical problem adopts:
A kind of presser sensor pulley stool footmuff, comprise housing, described housing is provided with stool pin groove, spring cavity and pulley chamber, stool pin groove is provided with locking device, be provided with spring and cylindrical piece in spring cavity, and spring cavity chamber wall is provided with by-pass cock, in pulley chamber, be provided with vibration-damping sheet and pulley, described spring is fixedly connected with cylindrical piece, and cylindrical piece is fixedly linked with vibration-damping sheet and pulley respectively by connecting rod.
Further, described locking device is the rotary type bolt structure with rubber layer.Locking device has the rotating part protruding housing, staff can prop up this projection and is inserted in stool pin by stool footmuff like a cork.After stool pin inserts stool pin groove, by rotating locking apparatus, rubber layer is firmly stuck on stool pin, effectively stool pin and this stool footmuff is fixed together.
Further, described cylindrical piece is provided with circular hole.
Further, the rotary type bolt structure of described by-pass cock to be end be truncated cone-shaped.Generally, by-pass cock end does not stretch into spring cavity: when needing the height locking pulley or regulate chair, by rotating by-pass cock, its truncated cone-shaped end being stretched into spring cavity, and is inserted into the circular hole on cylindrical piece.By-pass cock inserts the object that circular hole reaches locking pulley; Select the circular hole of diverse location, the object of adjusting seat height can be reached.
The beneficial effects of the utility model:
A kind of presser sensor pulley stool footmuff that this use is carried out, utilizes spring to control the flexible of pulley, controls pulley by the pressure that chair is responded to, and the movement of pulley can reduce and the friction on ground and send less sound.There is larger frictional force on common chair and ground, in mobile, send larger sound, and our principle just avoids such thing and occurs.When chair affords pressure time, pulley shrinks the stool footmuff entering chair, can not be moved because of pulley, different with the chair on the market with pulley, it can move when sitting down, but our design is that when having certain pressure, chair keeps transfixion.When pressure is little, pulley just appears at outside stool footmuff, can random mobile chair.And be designed with locking device, can help staff that this stool footmuff is inserted in stool pin, and rotatable locking device fix stool pin and stool footmuff.And be designed with by-pass cock, by rotating by-pass cock, reaching the object of locking or adjustment chair height, also can use the pulley on stool footmuff is not retracted.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of a kind of presser sensor pulley of the utility model stool footmuff;
Fig. 2 is the structural representation of cylindrical piece of the present utility model.
In figure: 1. housing, 2. stool pin groove, 21. locking devices, 211. rubber layers, 3. spring cavity, 31. springs, 32. cylindrical pieces, 321. circular holes, 33. by-pass cockes, 4. pulley chamber, 41 vibration-damping sheets, 42. pulleys, 43. connecting rods.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of presser sensor pulley stool footmuff, comprise housing 1, described housing 1 is provided with stool pin groove 2, spring cavity 3 and pulley chamber 4, stool pin groove 2 is provided with locking device 21, be provided with spring 31 and cylindrical piece 32 in spring cavity 3, and spring cavity 3 chamber wall is provided with by-pass cock 33, in pulley chamber 4, be provided with vibration-damping sheet 41 and pulley 42, described spring 31 is fixedly connected with cylindrical piece 32, and cylindrical piece 32 is fixedly linked with vibration-damping sheet 41 and pulley 42 respectively by connecting rod 43.
Further, described locking device 21 is the rotary type bolt structure with rubber layer 211.Locking device 21 has the rotating part protruding housing 1, staff can prop up this projection and is inserted in stool pin by stool footmuff like a cork.After stool pin inserts stool pin groove 2, by rotating locking apparatus 21, rubber layer 211 is firmly stuck on stool pin, effectively stool pin and this stool footmuff is fixed together.
Further, described cylindrical piece 32 is provided with circular hole 321.
Further, described by-pass cock 33 for end be the rotary type bolt structure of truncated cone-shaped.Generally, by-pass cock 33 end does not stretch into spring cavity 3; When needing the height locking pulley 42 or regulate chair, by rotating by-pass cock 33, its truncated cone-shaped end being stretched into spring cavity 3, and is inserted into the circular hole 321 on cylindrical piece 32.By-pass cock 33 inserts the object that circular hole 321 reaches locking pulley 42; Select the circular hole 321 of diverse location, the object of adjusting seat height can be reached.
The beneficial effects of the utility model:
A kind of presser sensor pulley stool footmuff that this use is carried out, utilizes spring 31 to control the flexible of pulley 42, controls pulley 42 by the pressure that chair is responded to, and the movement of pulley 42 can reduce and the friction on ground and send less sound.There is larger frictional force on common chair and ground, in mobile, send larger sound, and our principle just avoids such thing and occurs.When chair affords pressure time, pulley 42 shrinks the stool footmuff entering chair, can not be moved because of pulley 42, different with the chair on the market with pulley 42, it can move when sitting down, but our design is that when having certain pressure, chair keeps transfixion.When pressure is little, pulley 42 just appears at outside stool footmuff, can random mobile chair.And be designed with locking device 21, can help staff that this stool footmuff is inserted in stool pin, and rotatable locking device 21 fix stool pin and stool footmuff.And be designed with by-pass cock 33, by rotating by-pass cock 33, reaching the object of locking or adjustment chair height, also can use the pulley 42 on stool footmuff is not retracted.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to right.
