Description

A kind of handle has the door lock of pooling feature

Technical field

The utility model is related to a kind of door locks, are specifically the door lock that a kind of handle has pooling feature.

Background technology

The occasions such as front yard and office buildings, hospital of being in of panel lockset currently on the market are widely used.It is but existing The lockset used on the market be do not buffer, vibration damping, noise abatement sound function, these locksets can generate noise in use, No small influence is brought to the household to rest, the personnel to work, the patient to recuperate.To find out its cause, it is most main The noise source wanted is when shift fork and handle reset, the mutual shock between limiting component.In the prior art, due to handle volume Greatly, quality weight in order to make it that can automatically reset after being unlocked, is provided with resetting apparatus between handle and panel, when user rotates After handle is unlocked.With the disappearance for the torsion that user applies, quickly rebound resets handle under the action of resetting apparatus, handle band Limiting device fast ram on dynamic shift fork, so as to send operating noise, it is therefore necessary to make existing lock body structure into one Step improves, to reduce its operating noise.

Utility model content

The purpose of this utility model is to overcome prior art there are the shortcomings that, a kind of simple in structure, user is provided Just, shutdown noise can be reduced, reduces mechanical wear, a kind of handle to prolong the service life has the door lock of pooling feature.

The utility model aim is realized with the following methods：A kind of handle has the door lock of pooling feature, including lock Body and the handle being hingedly mounted on lock body are provided with square bar hole in handle, and square bar hole is sleeved on lock core drive rod surface, user Rotate handle drives lock core to move by square bar, realizes and unlocks and shut, it is characterised in that：Shift fork is provided in the lock body Piece, shifting fork piece are sleeved on square bar hole surface, and shifting fork piece is rotated with handle rotating, and drive is also hingedly equipped in the lock body Movable plate, driving piece middle part are hinged with lock body, and its one end is hinged by connecting plate and shifting fork piece, the piston of the other end and cushion dashpot Bar is hinged, and tail end and the lock body of cushion dashpot are hinged, and during handle rotating, cushion dashpot generates damping and slows down handle rebound velocity.

Hinge hole is provided in the middle part of the driving piece, hinged seat is provided in lock body and is connected with the hinge hole.

The hinged seat includes the fixing axle being fixed on lock body and the rotation for being sleeved on the fixing axle surface Set, turning set are fixed with hinge hole.

Driving piece, connecting plate and the cushion dashpot is distributed in square bar hole periphery in semi-surrounding structure.

The cushion dashpot is stretching buffer-type hydraulic buffer cylinder.

The beneficial effects of the utility model are：1st, simple and reliable for structure, production cost is low, and the market competitiveness is strong.2nd, locking Cushion dashpot is provided in vivo, cushion dashpot is by driving piece and connecting plate to be connected with handle, and when handle resets, cushion dashpot generates damping The rebound velocity of handle is reduced, so as to avoid the too fast generation noise of handle rebound velocity.3rd, the setting of piece and connecting plate is driven, is had Effect reduces the length of the arm of force, so as to make this structure more compact.

Fig. 3 is that structure diagram after partition plate is hidden in the utility model.

Fig. 4 is the utility model Standard figure.

Fig. 5 is that piece and connecting plate and cushion dashpot installation diagram are driven in the utility model.

Specific embodiment

Make specific further instruction to the utility model below in conjunction with the accompanying drawings.A kind of handle has the door of pooling feature Lock, including lock body 1 and the handle being hingedly mounted on lock body 12, is provided with square bar hole 3, square bar hole is sleeved on lock core in handle Drive rod surface, user rotate handle 2 and by square bar lock core are driven to move, realize and unlock and shut, it is characterised in that：Described Shifting fork piece 4 is provided in lock body 1, shifting fork piece 4 is sleeved on square bar hole surface, and shifting fork piece 4 is described as handle 2 rotates and rotates Lock body 1 in driving piece 5 is also hingedly installed, driving piece 5 middle part is hinged with lock body 1, and its one end passes through connecting plate 6 and shifting fork piece 4 is hinged, and the piston rod 71 of the other end and cushion dashpot 7 is hinged, and the tail end and lock body 1 of cushion dashpot 7 are hinged, when handle 2 rotates, delay It rushes cylinder 7 and generates to damp and slow down 2 rebound velocity of handle.

5 middle part of driving piece is provided with hinge hole 51, and hinged seat 8 is provided in lock body 1 and is connected with the hinge hole 51.

The hinged seat 8 includes the fixing axle 81 being fixed on lock body and is sleeved on turning for the fixing axle surface Dynamic set 82, turning set 82 is fixed with hinge hole.

Driving piece 5, connecting plate 6 and the cushion dashpot 7 is distributed in 3 periphery of square bar hole in semi-surrounding structure.

The cushion dashpot 7 is stretching buffer-type hydraulic buffer cylinder.

Operation principle：In switching process, the movement of shift fork piece is wherein set limited handle in this case on shifting fork piece Position notch, and is provided with limiting stand and is placed in the spacing breach, the setting of spacing breach so that this handle can only rotate it is certain Angle, so as to avoid the excessive influence feel of handle folding angle.

Further：As shown in figure 3, under normality, cushion dashpot is in compressive state.It opens the door when user pulls downwards handle When, handle drive shift fork rotate counterclockwise so that shift fork by connecting plate drive driving piece deflect, driving plate deflect when its The other end inwardly promotes cushion dashpot so that cushion dashpot inwardly bounces back.Wherein since the cushion dashpot in this case is stretches buffer-type, because When this cushion dashpot is inwardly compressed, damping will not be generated.

After user looses one's grip, handle inverts reset under the action of resetting spring so that lockset is closed.Handle In reseting procedure, shifting fork piece pulls driving plate to turn round by connecting plate, and the piston rod of cushion dashpot at this time is slowly pulled out, held Hand slowly resets closing, so as to avoid door lock reset speed in traditional technology it is too fast caused by sound and abrasion, make in promotion While with texture, avoid lockset inter deterioration is too fast from influencing its service life.

Further：It may be such that buffer utilizes smaller stroke using the structure of driving piece and connecting plate transfer in this case The buffering to shift fork can be realized, so as to reduce the volume of buffer and movement travel so that lockset internal structure is more compact It is compact, work efficiency also higher, therefore can be widely used to promote.

The basic principle of the utility model and main feature and the advantages of the utility model has been shown and described above.One's own profession The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description Simply illustrate the principle of the utility model, on the premise of not departing from the spirit and scope of the utility model, the utility model is also Various changes and modifications are had, these various changes and improvements fall within the scope of the claimed invention.
