Description

A kind of punching type stapler head of abrupt release

Technical field

The utility model relates to a kind of office appliance, specifically a kind of stapler of bound book or order folding machine.

Background technology

Nowadays stapler has become the essential product of office, for we provide a kind of desirable means that plurality of sheets of paper bookbinding is integrated and is preserved.Conventional stapler comprises stapler head and the base that anamorphoser is housed, and the pressing action of armrest portion completes forwarding; But because human strength is comparatively limited, (different users's application of force size is also divided power, and there is no impact velocity while ordering into paper), current binder can only be bound the sealing that thickness is not more than paper (weight is 70 grams of left and right), paper bag or the packing plastics bag of 15 pages, therefore cannot tackle the bookbinding demand (staple cannot effectively penetrate all paper and cause binding effect and bookbinding aesthetics is all had a greatly reduced quality) with larger thickness paper, be further improved.

Utility model content

The purpose of this utility model is the deficiency overcoming in above-mentioned background technology, a kind of abrupt release punching type stapler head is provided, this stapler head should be able to be bound the paper of larger thickness, and have simple in structure, easy to use, bind laborsaving and bind effective feature.

The technical solution of the utility model is: a kind of abrupt release punching type stapler head, is characterized in that: this stapler head comprises frame, be vertically fixed on slideway bar in frame, can vertically be positioned at slidably lower platen on slideway bar, be sleeved on slideway bar and stage clip that upwards pressing plate is depressed on top, be positioned on lower platen for clashing into the Chong Ding mechanism of staple and the hub lock releasing that Yu Chongding mechanism is used in conjunction with;

Described Chong Ding mechanism comprises that rushing of can vertically sliding along the sliding tray of lower platen order plate, be fixed on punching and order that sheet is ordered for clashing into rushing of staple in plate lower end, two ends are separately fixed at punching and order the extension spring that is used to knockout process accumulation of energy between plate upper end and lower platen;

Described hub lock releasing comprises the baffle plate that can rotate around horizontal axis, baffle plate is applied the torsion spring of clockwise moment of torsion and is horizontally fixed on punching and order plate left side and lock with the lock hole on baffle plate right side the securing rod that release coordinates.

Described baffle plate upper end is manufactured with the solution locking face of constant slope, is manufactured with and the thrust face of separating locking face and matching on described lower platen.

Described frame comprises base plate and support.

The beneficial effects of the utility model are:

Punching of the present utility model is ordered plate in lock release and is rushed under the cooperatively interacting of binding device and can obtain the speed that moves down being exceedingly fast, making punching order sheet can clash into staple with larger momentum, staple moment is squeezed in paper the paper of 80 grams (can easily hammer into number of pages and be 40 and weight be); Structure of the present utility model is comparatively simple simultaneously, and (using method is identical with common stapler) very easy to use, forwarding is comparatively laborsaving, and the paper after bookbinding has clean and tidy beautiful outward appearance, can obtain gratifying bookbinding effect.

The specific embodiment

Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.

As shown in Figure 1, a kind of abrupt release punching type stapler head, comprises frame, slideway bar 2, lower platen 3, stage clip 3-1, Chong Ding mechanism and hub lock releasing; Frame comprises base plate 1-1 and is fixed on the support 1-2 on base plate; Slideway bar is vertically fixed on support, is also set with stage clip on slideway bar; Lower platen can vertically be positioned on slideway bar slidably, and the upper end of stage clip upwards suppresses the lower surface of lower platen; For the Chong Ding mechanism of clashing into staple, be positioned on lower platen and hub lock releasing and rush binding device and be used in conjunction with.

In Chong Ding mechanism: punching is ordered plate 4-1 and vertically passed through from top to bottom lower platen and punching and order plate and can vertically slide along the sliding tray 3-2 of lower platen, the top and bottom that plate is ordered in punching lay respectively at the above and below of lower platen; For clash into rushing of staple order sheet 4-2 be fixed on punching order plate lower end; The two ends of extension spring 4-3 are separately fixed at punching and order between plate upper end and lower platen, and extension spring can be used for for rushing the knockout process accumulation of energy of binding device.

In hub lock releasing: baffle plate 5-1 can be rotatably fixed to (5-6 is hinged by rotating shaft) on support around horizontal axis; Torsion spring 5-2 is sleeved in rotating shaft and the baffle plate of exerting pressure forces baffle plate to rotate along clockwise direction (clockwise direction in figure); Lock hole 5-3 is formed on baffle plate its right end face (right direction in figure); Horizontally extending securing rod 5-4 is fixed on punching and orders plate left side, thereby the left end of securing rod is inserted in to stop baffle plate to rotate along clockwise direction and stop punching to order plate in lock hole and vertically moves.

Further, baffle plate upper end also makes a solution locking face 5-5, and this release mask has certain gradient (and the angle of horizontal direction is between 30 ° to 70 °); On lower platen, be manufactured with and the thrust face 3-3 that separates locking face and match, on thrust face, have and separate the matched gradient of locking face (and the angle of horizontal direction is between 30 ° to 70 °); Thrust face can promote baffle plate with solution locking face formation sliding friction and rotate counterclockwise, thereby plays the effect of rushing binding device that discharges.

Operation principle of the present utility model is as follows:

The first step, lock-out state, as shown in Figure 1: first install staple 9 and put into paper 10; Now lower lock block is positioned at baffle plate top (thrust face keeps at a certain distance away with solution locking face), thereby securing rod is positioned at cooperation in lock hole, stops baffle plate to clockwise rotate, and hub lock releasing locks Chong Ding mechanism;

Second step, user promote lower platen and move down, as shown in Figure 2: because securing rod is positioned at, make in the folding process of lower platen punching order plate cannot to move down in lock hole, so extension spring is elongated gradually;

When lower platen is moved downward to certain distance, thrust face will be suppressed to the solution locking face of baffle plate, because release mask has certain gradient, according to the known lower platen of force resolution, be applied to pressure on baffle plate and can be converted into and promote the thrust that baffle plate rotates around the shaft in the counterclockwise direction, thereby so between thrust face and solution locking face, will form sliding friction promotion baffle plate and rotate in the counterclockwise direction;

The 3rd step, release conditions, as shown in Figure 3: when baffle plate turns to certain angle, securing rod is by the restriction in the hole that goes out of lock, now hub lock releasing liquidates releasing to order the locking (now thrust face still keeps in touch state with solution locking face) of mechanism, therefore the plate of rushing to summit moves down at a terrific speed under the effect of tension spring tension, and (staple is separately carried by book pin conveying mechanism with larger momentum, to clash into staple; Book pin conveying mechanism is conventional mechanism, in figure, omits) and staple is squeezed in paper, then by anamorphoser, the tip of staple is bent, thus stapled one piece of staple;

The 4th step, recoil state, as shown in Figure 1: user discharges lower platen, under the thrust of stage clip, lower platen He Chongding mechanism moves up simultaneously; Now baffle plate rotates along clockwise direction under the promotion of torsion spring, and the securing rod moving upward is repositioned in lock hole; The utility model is got back to the state of the first step.
