Abstract
The utility model discloses a bolt clearance compensation adjusting device, which comprises a hollow bolt (8) and a clearance compensation tongue (1), wherein one side or both sides in the front of the hollow bolt (8) is/are provided with elongated square holes (6); the front end of the clearance compensation tongue (1) is provided with a mounting hole (5); one side of the clearance compensation tongue is provided with an inclined plane part (2); the middle of the clearance compensation tongue is provided with an elongated notch (3); the clearance compensation tongue (1) is provided with a spring eye (4); a bayonet lock (11) of the clearance compensation tongue (1) is movably arranged on the elongated square holes (6) of the hollow bolt (8); the elongated notch (3) of the clearance compensation tongue (1) is provided with a reset spring (7); one end of the reset spring (7) is arranged in the spring eye (4); and the other end of the reset spring is fixed on a lug of the hollow bolt (8). After the structure is adopted, the bolt clearance compensation adjusting device has the characteristics of simple and reasonable structure, small noise, good use effect and the like; clearance is automatically adjusted and a door leaf does not sway.
Description
Technical field
The utility model relates to the lockset fixture that uses on a kind of security door, the particularly a kind of dead bolt gap compensation adjustment device that can eliminate gap between dead bolt and the dead bolt hole automatically.
Background technology
At present, the common lockset that uses on the security door, in any case its main dead bolt changes the rectangular structure that is generally hollow, adopt this structure to be not only mechanism's intensity height, and be that the pick-proof performance is good, dead bolt must leave enough big fit clearance in order to cooperate time turnover free light with the dead bolt hole of doorframe between dead bolt and the dead bolt hole.But this structure in use has the following disadvantages: the one, because excesssive gap between dead bolt and the dead bolt hole, security door in use touches and all can produce door leaf and constantly rock because of being subjected to wind-force or pedestrian, thus the generation noise; The 2nd, owing to excesssive gap between dead bolt and the dead bolt hole, will certainly reduce the pick-proof performance and the result of use of security door, for this reason, many producers and person skilled have been carried out R and D, product does not emerge but also have reasonably so far.
Summary of the invention
Be to overcome the problems referred to above that the dead bolt of existing common lockset exists, the purpose of this utility model provides a kind of simple and reasonable, automatic adjusting play, noise is little, the pick-proof performance is good dead bolt gap compensation adjustment device.
The technical scheme that its technical problem that solves the utility model adopts, it comprises hollow dead bolt, the gap compensating tongue, one-sided or the bilateral of hollow dead bolt front portion is provided with the strip square hole, the front end of described gap compensating tongue is provided with fixing hole, the one side is provided with the chamfered portion greater than strip square hole width, the thickness of chamfered portion is greater than the gap between dead bolt and the dead bolt hole, its middle part is provided with the strip breach, the gap compensating tongue of strip breach inboard is provided with spring eye, the gap compensating tongue is movably arranged on the strip square hole of hollow dead bolt by the bayonet lock that is fixed on the fixing hole, on the strip breach of gap compensating tongue, be provided with back-moving spring, back-moving spring one end is arranged in the spring eye, and the other end is fixed on the hollow dead bolt projection of strip square hole afterbody.
After adopting said structure, the utility model has following advantage and effect: the one, when closing, because the thickness of chamfered portion is greater than the gap of reserving between dead bolt and the dead bolt hole, under the effect of back-moving spring, the gap compensating tongue can slide on the strip square hole of dead bolt, till eliminating the gap, thereby avoided door leaf because of rocking that gap between dead bolt and the dead bolt hole causes; The 2nd, owing to eliminated gap between dead bolt and the dead bolt hole, make to cooperate closely between door leaf and the doorframe, not only sealing effectiveness can be improved, and the pick-proof performance can be improved.

1 gap compensating tongue wherein, 2 chamfered portions, 3 strip breach, 4 spring eyes, 5 fixing holes, 6 strip square holes, 7 back-moving springs, 8 dead bolts, 9 doorframes, 10 dead bolt holes, 11 bayonet locks.
The specific embodiment
Fig. 1 is to shown in Figure 5, specific embodiments for a kind of dead bolt of the utility model gap compensation adjustment device, it comprises hollow dead bolt 8, gap compensating tongue 1, one side of hollow dead bolt 8 front portions is provided with strip square hole 6, the front end of described gap compensating tongue 1 is provided with fixing hole 5, the one side is provided with the chamfered portion 2 greater than strip square hole 6 width, make gap compensating tongue 1 can be when strip square hole 6 easy motions adjust gap between dead bolt 8 and the dead bolt hole 10 by the inclined-plane, its middle part is provided with strip breach 3, the gap compensating tongue 1 of strip breach 3 inboards is provided with spring eye 4, gap compensating tongue 1 is movably arranged on the strip square hole 6 of hollow dead bolt 8 by the bayonet lock 11 that is fixed on the fixing hole 5, on the strip breach 3 of gap compensating tongue 1, be provided with back-moving spring 7, back-moving spring 7 one ends are arranged in the spring eye 4, and the other end is fixed on hollow dead bolt 8 projections of strip square hole 6 afterbodys.
The utility model work is as follows: enter in the process of dead bolt hole 10 at dead bolt 8, because the maximum ga(u)ge of chamfered portion 2 is greater than the gap between dead bolt 8 and the dead bolt hole 10, the chamfered portion 2 of gap compensating tongue 1 contacts with the inlet of dead bolt hole 10, dead bolt 8 is adjusted the contact site of chamfered portion 2 automatically behind the elastic force that overcomes back-moving spring 7, till eliminating the gap.
The structural representation that Fig. 6 cooperates with the dead bolt hole 10 of doorframe 9 for existing dead bolt 8, dead bolt 8 will keep certain clearance all the time with dead bolt hole 10, can guarantee that just dead bolt 8 turnover dead bolt holes 10 are free light.
