Description

The dual spring buffer displacement bolt apparatus of tubular lock

The utility model relates to a kind of bolt apparatus.

In the classification form of lockset, the kind of drive according to the keeper keying, and can generally be divided into cylinder-type lock and tubular lock construction, as application case number the 7621210 No. four " structure-improved of cylindrical disability lock lock body ", and application case number the 76212104 chases after " structure-improved of cylindrical disability lock lock body appends one " No. 01, is the masterpiece of traditional cylindrical lock.

And as application case number the 8020 three nine-day periods after the winter solstice four No. seven " structure-improved of tubular disability lock lock body ", and application case number the 8020 three nine-day periods after the winter solstice four No. eight " structure-improved of tubular disability slip bolt ", it then is present common tubular lockset, wherein, " structure-improved of tubular disability slip bolt ", main between housing, be equipped with two mutually prominent switch block, drive plate, the serial connection of fit plate body and rotating plate, arm-tie and open the bolt head, again accessory plate is placed in outside the housing, and cooperates panel to be riveted and be fixed in the end of door-plate.

Again, the bolt structure development of tubular lock so far, various in order to reduce the composition member, and time-consuming problem such as bothersome is gone up in assembling, and as shown in Figure 7 the available assembling of keeper 8 structure designs is arranged, its shell block 80 is to be formed by two relative side body institute involutions, wherein, shell block 80 top bottoms are provided with chute 85, movably interlock frame 90 is set in the shell block 80, these interlock frame 90 top bottoms are provided with slotted hole 91, slotted hole 91 rear ends are bent into lug 92, interlock frame 90 front ends are provided with dead bolt 97, and a spring 86 is set in dead bolt 97 rear ends, spring 86 rear ends are resisted against baffle plate 83 front ends set on the base plate 81 of shell block 80, again, the hole 82 that is pivoted is set on the base plate 81 of shell block 80, axle sleeve 93 both sides can be arranged in the hole 82 that is pivoted, in this axle sleeve 93 square opening 94 is set, can wear wherein for the drive link of tubular lock, axle sleeve 93 front ends are provided with cam 95, cam 95 two side ends form curved arc face 96, the terminal hook portions 961 that form of curved arc face 96, being pivoted of axle sleeve 93, the hook portion 961 that can make cam 95 is passed by the slotted hole 91 of interlock frame 90, and insert in the chute 85 of shell block 80, therefore, when the handle of tubular lock rotated, drive link that promptly can tubular lock came rotary sleeve 93 to be rotated, and can drive cam 95 rotations, and utilize the hook portion 961 of both sides to promote interlock frame 90 backward, make dead bolt 97 compressible spring, 86 displacements and enter in the panel 87, reach the effect of opening door-plate.

Keeper 8 structures of this tubular lock, though have the characteristic that structure is simplified and is easy to assemble, yet, the setting of single spring 86, in order to consider the steadiness of locking, the rigidity of this spring 86 need increase and could satisfy, and the rigidity of spring 86 is in case increase, make that then the cushion effect quantitative change of closing the door is big and more firm, and must bestow bigger strength pushing door-plate, just can make dead bolt 97 compress spring 86 with the relative pushing and pressing of doorframe slide plate via cambered surface 971, thus, promptly be easy to generate and send bigger collision sound at closing time, again, the rotation of axle sleeve 93, make the hook portion 961 of cam 95 can spur 90 displacements of interlock frame, and pull back dead bolt 97 and the compression spring 86 strength, all be to act on the single spring 86, therefore, spring 86 is easy to generate the shortcoming of elastic fatigue, cause spring 86 to be subjected to the elastic force of force compresses and answer thereby weaken and loose, neck-in deficiency when causing dead bolt 97 to give up the throne, and outer panel 87 outsides that are exposed at a little, so, to open door-plate again, promptly cause the endoporus clip of dead bolt 97 front ends and doorframe slide plate easily, in the course of time then easily thereby cause the damage of lock body, for this reason, its single spring 86 form is set, practicality is not good enough and do not have industrial utilization.

The purpose of this utility model provides a kind of dual spring buffer displacement bolt apparatus of tubular lock, it is the spring design that forms two road different rigidities in keeper, make its active force of closing the door and opening the door, the spring by different rigidity is born respectively, and can reach gentle suitable property at closing time.

The purpose of this utility model is achieved in that a kind of dual spring buffer displacement bolt apparatus of tubular lock, movable interlock frame is set in shell block, and rotatable cam, this cam is to be convexly set in the axle sleeve surface, square opening interlock frame front end is set in the axle sleeve dead bolt is set, shell block is involuted by relative side body, the hole that is pivoted is set on the base plate of side body, the tool axle sleeve that is pivoted in it, the both sides, hole that are pivoted are provided with baffle plate, on the wing plate of side body chute is set, the interlock frame is arranged in the shell block, and both sides are positioned between the wing plate of baffle plate and side body, and the shell block front end is provided with panel and inner panel, the dead bolt front end is passed by the hole of panel and inner panel, it is characterized in that:

The dead bolt rear end is provided with axostylus axostyle, and shaft rod upper sleeve is established the little spring of rigidity, and the axostylus axostyle rear end is arranged in interlock frame front end, and spring rear end is resisted against interlock frame front end face; Interlock frame inboard is provided with the big spring of rigidity, and the spring front end is resisted against interlock frame front end medial surface, and spring rear end is resisted against the baffle plate front end face.

Described dead bolt rear end is provided with the inside groove and the water jacket of hierarchy type, and the dead bolt side is provided with and penetrates inside groove, and the axostylus axostyle front end is provided with locating hole, and the axostylus axostyle front end inserts inside groove, and can insert the perforation of dead bolt and the locating hole of insertion axostylus axostyle by latch.

Described interlock frame front end is provided with the hole clipping of rectangle, and the axostylus axostyle rear end is provided with the clamping block of rectangle, and the clamping block of axostylus axostyle inserts in the hole clipping.

Relative perforation is set on described panel and the inner panel.

Because adopt such scheme: door-plate is easy to cut out and can alleviate the sound of impact, and, the spring setting that another rigidity is big, the firm effect in the time of can having locking concurrently.

Below in conjunction with drawings and Examples the utility model is further specified.
