Abstract
The utility model discloses a kind of frictional door knobs, it is made of idler wheel, holder, brake block, brake frame, spring, spring shim, mounting plate, stop nut, control hand handle, adjusting nut and pull rod etc., the frictional door knob of the utility model is all using mechanical structure, it is simple in structure, reliability is high, and cost is relatively low when mass production.
Description
Technical field
The utility model is related to a kind of building facilities technical field, especially a kind of frictional door knob.
Background technology
Door knob is the device that door leaf is fixed after door leaf opens or closes, and existing door knob is mainly magnetic-type and clamping type two
Kind, can only fix door leaf a fixed position as the door knob for fixing door leaf after enabling, can not meet simultaneously door leaf standard-sized sheet,
Half-open and a variety of positions such as shut the door fixed demands, at the same the installation of these door knobs all occupy certain space and influence it is beautiful with
Cleaning works.To meet the fixed demand of a variety of positions such as the half-open, standard-sized sheet of door leaf, people have to install door knob in selection
While, door leaf also is auxiliarily fixed with door plug, use is very inconvenient.
Utility model content
The technical problems to be solved in the utility model is：A kind of frictional door knob is provided, idler wheel is installed on door leaf, is being rolled
Brake gear is set on wheel, using the door leaf that frictionally secures between idler wheel and floor, realizes the fixed function after door leaf is opened.
The specific technical solution that the utility model is taken is：
A kind of frictional door knob, by idler wheel, holder, brake block, brake frame, spring, spring shim, mounting plate, locking spiral shell
The compositions such as female, control hand handle, adjusting nut and pull rod, wherein the pedestal lower end is equipped with rotatable idler wheel, and interlude is
Plain shaft structure, upper end are helicitic textures, are equipped with brake frame moving up and down from bottom to top, spring, spring shim, adjust spiral shell
Female, mounting plate and stop nut；Brake block is installed on the brake frame, be close to idler wheel outer rim under the effect of spring force and
Its rotation is hindered, door leaf is made to be in stationary state, the size of spring force and brake weight is can adjust by turning adjusting nut；It is described
Mounting plate is connected by the screw hole of itself and the upper end of holder, and is connect with control hand handle by pin shaft structure, the both ends of pull rod
It is connect respectively with control hand handle and brake frame by pin shaft structure, control hand handle is up pulled, brake frame is driven by pull rod
It is moved up together with brake block, so that brake block is detached with the outer rim of idler wheel and idler wheel is made to be freely rotated can free moving type with door leaf
State.
Further, the effect of the stop nut is to keep mounting plate and being fixedly connected for holder relatively reliable.
Further, the frictional door knob is fixedly connected by mounting plate with door leaf.
The utility model additionally provides the application of above-mentioned frictional door knob, and main application can carry out axis in door leaf around hinge
On the door of line rotation.
The frictional door knob of the utility model compared with prior art, has the advantages that：
1. occupying little space and beautiful：
Compared with existing magnetic-type door knob, frictional door knob is small, and installation occupies little space and more beautiful, also more
Cleaning is facilitated to work.If with door leaf, Aided design manufactures simultaneously, and frictional door knob is embedded in door-plate, and this advantage will
It is more prominent.
2. can fix door leaf at an arbitrary position, door knob function is extended：
Door leaf can only be fixed door leaf by existing magnetic-type, clamping type door knob in the position of setting, using frictional door knob
Door leaf can be fixed at an arbitrary position, realizes that door leaf is half-open and ventilation, be left unlocked or unlatched and facilitate the functional requirements such as disengaging.
3. mitigation door leaf couples stress with doorframe：
Door leaf is usually coupled with 2 pairs or more of hinge with doorframe, generally all in the stress of cantilever beam, using rubbing
Erasing door knob can increase upward support force at the inferior horn of door leaf hinge opposite side, so as to improve door leaf arm beam stress state simultaneously
Improve the reliability of entire door.
4. simple in structure, low cost：
Frictional door knob is simple in structure all using mechanical structure, reliability height, and cost is relatively low when mass production.
Description of the drawings
Fig. 1 is the frictional door knob structural schematic diagram of the utility model；
Fig. 2 is the frictional door knob use state diagram of the utility model；
In figure, 1. idler wheels；2. holder；3. brake block；4. brake frame；5. spring；6. spring shim；7. mounting plate；8. anti-
Loose nut；9. controlling hand handle；10. adjusting nut；11. pull rod；12. door leaf；13. hinge.
Specific implementation mode
The utility model is described further below in conjunction with the accompanying drawings.
Embodiment
A kind of frictional door knob, structure is as shown in Figure 1, by idler wheel 1, holder 2, brake block 3, brake frame 4, spring 5, bullet
The compositions such as spring gasket 6, mounting plate 7, stop nut 8, control hand handle 9, adjusting nut 10 and pull rod 11, wherein, under the holder 2
End rotatable idler wheel 1 is installed, interlude is plain shaft structure, and upper end is helicitic texture, be equipped with from bottom to top can on move down
Dynamic brake frame 4, spring 5, spring shim 6, adjusting nut 10, mounting plate 7 and stop nut 8；It is equipped on the brake frame 4
Brake block 3 is close to 1 outer rim of wheel under the action of 5 elastic force of spring and hinders its rotation, so that door leaf is in stationary state, pass through
Turn the size that adjusting nut 10 can adjust spring force and brake weight；The mounting plate 7 is upper by the screw hole of itself and holder 2
End connection, and connect with control hand handle 9 by pin shaft structure, the both ends of pull rod 11 pass through pin shaft structure and control hand handle 9 respectively
It is connected with brake frame 4, control hand handle 9 is up pulled, driven brake frame 4 to be moved up together with brake block 3 by pull rod 11, make
Brake block 3 detaches with the outer rim of idler wheel 1 and idler wheel is made to be freely rotated can free movement state with door leaf.
The effect of the stop nut 8 is to keep mounting plate 7 and being fixedly connected for holder 2 relatively reliable.
As shown in Fig. 2, the frictional door knob is fixedly connected by mounting plate 7 with door leaf 12, the door leaf 12 can be around
The axis of hinge 13 rotates.
