Door is the important device in house, and door is often in after opening don't care state, and slight air flow will change Become its opening angle, in order to prevent it is this unwillingly change people devise a kind of hardware article door knob, it be typically all by Be fixed on the door leaf back side is the circular iron block part for touching ferrum and the magnetic piece component two parts composition for being fixed on wall side, touches ferrum and door Fan is fixed together magnetic piece component together with wall side ground or wall fixation, and magnetic piece and its auxiliary member are all and rigidly fix connection, Adsorb by the magnetic attraction of magnetic piece and touch ferrum to fix the door leaf after opening, generally this adsorption is very reliable, Door leaf outside even directly facing room also will not change opening angle by wind easily, however, this articles for use is in actually used process In also expose some problems：When door leaf is opened near fixed position（Touch ferrum and touch when being attached together with magnetic piece soon）Magnetic The magnetic adsorptive power of block will the ferrum that will touch of strength be drawn to itself cause larger collision sound, and pass through to wrap up or paste one The soft damping thing of layer can largely weaken the reliability of fixed absorption to eliminate again during this sound；Meanwhile, door to be closed Fan attempt to pull open be attached together touch ferrum and be similarly no small sound to be produced because of the shake of door leaf during magnetic piece, while This operation for attempting to pull open also is very much hard.So, it is a kind of both there is strong absorption affinity or be avoided that in use produce larger sound Sound and easy-operating door knob can be more popular to people.

The content of the invention

The purpose of the present invention is to provide a kind of new technical scheme Soundless door stop of door knob, it can eliminate it is above-mentioned not Foot.

The technical scheme is that what is be achieved in that, it includes and touches ferrum, backplate, magnetic piece, touching lever, base plate, the touching lever For one section of pipe, thereon end is connected to the rectangular-shaped of a setting by the respective protrusions part on tube wall and bearing pin activity Knee, the upper end of knee installs backplate and magnetic piece and towards touching the close direction of ferrum；Fill on the bottom of from touching lever tube wall A spiral compression spring and cushion block are equipped with, the contact that the lower end of spring, cushion block and knee is all nervous offsets.

The invention has the beneficial effects as follows:Can significantly weaken magnetic piece with touch initial magnetic adsorptive power when ferrum is contacted soon from And weaken collision sound, also can be so that separating that to touch the operation that ferrum combined with magnetic piece easily many when simultaneously closing off door leaf.

Description of the drawings：

Fig. 1 is the overall front view of each component locations state of the design door knob when fixed position after door leaf is opened（I.e. Door leaf is gradually moved into larger opening angle by little opening angle and is not yet touched backplate and magnetic piece, not yet reaches maximum opening angle When）.

Fig. 2 is door leaf in overall front view when being close to maximum opening angle（Door leaf near maximum opening angle state, i.e., Touch ferrum to start mutually to attract to touch the location status that ferrum touches one jiao of backplate with magnetic piece）.

Fig. 3 be door knob be in normal work when overall front view（Door leaf fully opens the shape reached after maximum opening angle The working condition of state, i.e. door knob in absorption）.

Fig. 4 is the top view of Fig. 3 states.

In each figure, 1 is door leaf, and 2 to touch ferrum, and 3 is backplate, and 4 is magnetic piece, and 5 is knee, and 6 is bearing pin, and 7 is cushion block, and 8 is to touch Bar, 9 is spring, and 10 is base plate.

Specific embodiment：

Below in conjunction with the accompanying drawings illustrating the design.

In general, why door knob collides out sound and is primarily due to two collision knots when ferrum making contact is touched in magnetic piece absorption The combination in conjunction face is what the combination angle of 0 ° of entire surface was caused, because two faces of move toward one another are if the combination at 0 ° of angle Collide certainly big more many than the sound that the combination collision at not 0 deg angle is produced, i.e., if this contact of two faying faces is combined Then problem just can be solved for angle increase；As the design illustrates shown in Fig. 1, Fig. 2, Fig. 3, the fixed circle on the back side of door leaf 1 Ferrum 2 is touched, touching lever 8 is then fixed on the ground of wall side by base plate 10, touching lever 8 is one section of pipe, and thereon end is by tube wall A pair of respective protrusions parts and the activity of a bearing pin 6 be connected to a rectangular-shaped knee 5 for standing vertically, the upper end dress of knee Put backplate 3 and magnetic piece 4, magnetic piece is wrapped up by backplate, as shown in figure 4, the effect of backplate mainly keep off shield magnetic piece avoid touching ferrum it is straight Collision is connect, the upper end direction of knee touches the close direction of ferrum；A helical compression is installed on the bottom of from the tube wall of touching lever 8 Spring 9 and cushion block 7, all nervous contact in the lower end of spring 9, cushion block 7 and knee 5 offsets, the thickness of cushion block preferably it is bigger with Mutually do not block with touching lever inwall not when ensureing that it is moved up and down.In using operation, when opening door leaf 1 reaches larger opening angle ferrum is touched 2 not yet touch backplate 3 and when magnetic piece 4, door leaf is not yet reached at maximum opening angle, touch the left side that ferrum 2 moves closer to backplate 3, Now touch the magnetic attraction between ferrum 2 and magnetic piece 4 to start to occur and play a role, cause knee 5 to be intended to touch the direction of ferrum 2 , there is a deflection angle relative to its home position in deflection, and as shown in Figure 1 and Figure 2, wherein Fig. 2 clearly shows that out two This angle of faying face, produces when colliding relative to the combination that two faces for contacting are this not 0 deg angles of original structure that 0 ° of angle combines The sound obtained it is obvious reduce abatement, touch combine after spring 9 active force effect under can return to its original position i.e. Its stable rest position, such as Fig. 3, Fig. 4 shape, in this process, touch the impingement area of ferrum in the left end for initially touching backplate There is no the combination angle that the combination that faying face is collided in the same collision of absorption at the beginning two as usual is just 0 ° of entire surface during face But combination is contacted with the combination angle of a not 0 deg, the complete fit-state of faying face, such elder generation are returned after combination The effect for reducing collision sound can be produced to the structure that face contacts again by a contact；In addition, touching ferrum in the operation for closing door leaf With magnetic piece（Backplate）Disengaging process be exactly this opened door leaf process contrary operation, equally can through one collide faying face By 0 ° to not 0 deg with reference to angle until the process for gradually changing for completely disengaging from, i.e., by Fig. 3 to Fig. 2 again to Fig. 1, such disengaging connects Tactile feature is not similarly that entire surface carrys out detached but, closing detached with certain contact inclination angle with the angle of departure at 0 ° of angle Also can be same in the operation of door leaf it is laborsaving easily many because by the attracting faces of two magnetic with the separation of not 0 deg angle（It is exactly first Separation is started from one side）Than the separation at 0 ° of angle（Exactly separating whole plane parallel shape）Can be laborsaving a greater part of.
