Description

A kind of steel casement door lock of multidirectional many tongues

The utility model relates to a kind of steel casement door lock of multidirectional many tongues.Be relatively poor to unstability, the flexibility ratio of existing two flappers lock, can only the locking folk prescription to and the high improvement of manufacturing cost, be applicable to various pairs of tongues, multi-bolt door lock structure.

Existing pair of flapper is locked in when locking a door, and by the rotation of the monodentate on the handle, backs down the lockmaking piece for spring in advance, and then stirs dead bolt and tooth bar moving slow-witted tongue of generation stretches out lock housing, reaches the effect of lock; Particularly unblank right, structure is just quite complicated, at this moment must be the monodentate on the handle by opposing that pin rotates 360 °, back down earlier lockmaking piece again for spring, just can stir indentation lock housing behind dead bolt and the tooth bar moving slow-witted tongue of generation, also must continue change certain angle then, stir again that another shift fork part drives in the oblique tongue indentation lock housing, door just is opened; Practice has proved that many users' lock do not open, do not lock, and all belongs to parts such as gear, rack structure and shift fork and cooperates unreasonablely, or certain part deformation blocked, the fault that causes, give user Dai Lai certain person property lose; If it is more complicated to increase its structure of above-below direction dead bolt structure on two flapper lock constructions, problem is more, can occur having locked not opening, and has opened the corresponding increase greatly of the accident probability of not locking, and therefore the defective of lock is many.

The purpose of this utility model just provides a kind ofly locks the improvement locking device at existing two flappers, reduce spare and accessory parts, make the stable performance of lock, flexibility ratio reaches with low cost well, but the steel casement door of the multiple dead bolt of a plurality of directions of locking lock has the advantages that to improve two flapper amounts and function again.

The utility model purpose can realize by following measure: a kind of steel casement door locking device of multidirectional many tongues, by what set up with horizontal center line angle at 45 on the common bolt plate (15)〉two oblique chutes of guiding of shape, matched in clearance downslide untie-sell (14), slow-witted tongue junction plate (13) and go up sliding pin (23), last slow-witted tongue junction plate (22) down; During, left movement right when bolt plate (15), two guiding bevel frictions that oblique chute is done of shape change directions move, up and down two sides' slow-witted tongue just stretch out, indentation, reach locking, the purpose of unblanking.In addition, on same of bolt plate (15), fix again two slow-witted dead bolts (7), (9) and tiltedly tongue (8) but, also set up the correlated parts device that the inclined-plane promotes upper and lower slow-witted tongue; Therefore locking, can lock five dead bolts of three different directions when opening the door, and can reach the oblique tongue function of two flappers locks.

The utility model has improved the device of lock on the basis of existing pair of flapper lock, but its structure design simple, reduced part, low cost of manufacture and three different directions of locking, overcome the defective of existing lock.So it is stable that the utility model has been realized lockset, flexibility is good, the life-span is long, save raw material and increased the firm function of locking, and has preferable performance.

Concrete structure of the present utility model is drawn by the following drawings:

Fig. 1: be the lock body portion dress broken section front view of utility model.

Fig. 2: be the bolt plate front view of utility model.

Fig. 3: be the bolt plate vertical view of utility model.

Fig. 4: be the oblique tongue front view of utility model.

Fig. 5: be the oblique tongue broken section vertical view of utility model.

Fig. 6: be the slow-witted tongue front view of utility model.

The utility model describes in detail below in conjunction with accompanying drawing and implements: for example shown in Figure 1: a kind of steel casement door locking device of multidirectional many tongues is by lock housing (1), interior handle cam (24); Being located at bolt plate (15) goes up and horizontal center line angle at 45〉two oblique chute devices of guiding of shape and upper and lower slide lock (23), (14), upper and lower slow-witted tongue junction plate (22), (13) three parts composition.First is partly coordinated by lock housing (1), interior handle cam (24), guide pad (16), spring (18), spring shim (19), middle spacer pin (20) and other relevant lock accessory; At first interior handle cam (24) is connected on the lock housing (1) with the associated part matched in clearance, can in 115 ° of scopes of regulation, rotate, a left side, right spring (18), be that matched in clearance is enclosed within outside the guide pad (16), can freely stretch, four spring shims (19) can be prevented the beginning and end end of two ends spring, offside ejection effect, it is outer also to be enclosed within guide runner (16), middle spacer pin (20) riveting is in the middle of guide pad (16), guide pad (16) is embedded in two grooves in lock housing top, can limit bolt plate (15) and be in two ends and be subjected to Spring balanced, reaches meta half lock effect.Fig. 2, shown in Figure 3: second partly is made of bolt plate (15) slide down untie-sell (23), (14) and upper and lower slow-witted tongue junction plate (22), (13); At first on bolt plate (15), process and horizontal center line angle at 45 two oblique chutes of guiding of shape, can play a driving role as bevel friction; Last sliding pin (23) is that to be fixed on the slow-witted upper and lower sliding pin of tongue junction plate (22) (14) be to be fixed on down on the slow-witted tongue junction plate (13), they are motion in two skewed slots of bolt plate (15) and lock housing vertical guide slot respectively, changes its direction of motion and reaches the effect of locking the Xiamen.As Fig. 4, Fig. 5, shown in Figure 6: the 3rd partly by formations such as oblique tongue (8), slow-witted tongue (7), (9) and upper and lower slow-witted tongues; At first mill out whole tiltedly slow-witted tongues with the straight trough of bolt plate (15) material thickness and be embedded on the bolt plate (15), use six dead bolt rivets (10) that right-hand member and the slow-witted tongue that oblique tongue (8), slow-witted tongue (7), (8) firmly are riveted on bolt plate (15) is riveted on again on upper and lower slow-witted tongue junction plate (22), (13) again, has the function that increases door lock, save raw material, improve the effect of flexibility ratio.

Operating principle of the present utility model and operation instruction:

When locking a door, with interior handle cam (24) by being rotated down clockwise, two chutes stirring the right-hand member guiding of bolt plate (15) move right, the spring of left end chute compression at this moment enlarging sheet (19), and left end bullet Huang (18) moves right (position as shown in Figure 1) along guide pad (16); Insert in the doorframe button box the oblique tongue (8) of right-hand member, slow-witted tongue (7), (8) simultaneously, pins the right-hand of door; Untie-sell (14) and slow-witted tongue junction plate (13) and upward sliding pin (23) and last slow-witted tongue junction plate (22) down simultaneously glide, following in bolt plate (15) respectively, do the break-in campaign as bevel friction in the oblique chute of last guiding, and then promote the upper and lower side that upper and lower slow-witted tongue pins door.When opening the door, interior handle cam (24) is rotated up 90 ° by inhour, the top right-hand member chute compression right-hand member spring shim, right-hand member spring of stirring bolt plate (15) along guide pad (16) to left movement, at this moment in the oblique tongue (8) of right-hand member, slow-witted tongue (7), (8) retraction lock housing (1); Meanwhile, downslide untie-sell (14) and slow-witted tongue junction plate (13) and upward sliding pin (23) and last slow-witted tongue junction plate (22) down, do the break-in campaign as bevel friction in the oblique chute of upper and lower guiding in bolt plate (15) respectively again, and then promote in the upper and lower slow-witted tongue retraction door, and then continue inhour and rotate interior handle cam (24), oblique tongue (8) is just understood in the retraction lock housing in the time of 115 °, and door is opened.Continue to open at closing time, motion goes round and begins again.
