Description

Keeper

Technical field

The utility model relates to a kind of door lock assembly, especially a kind of keeper for timber.

Background technology

Keeper is one of vitals of mechanical lock, on to the antitheft design of timber, that large enterprises or small enterprise often all concentrate in the anti theft design of mechanical lock lock body or tapered end the antitheft improvement of timber or design, often ignored the improvement of keeper or design, what but the quality of the anti-theft effect of timber was leaned on is the perfect cooperation of keeper and mechanical lock lock body and tapered end, just can reach optimum efficiency, just think lower timber under lawless person's clashing, keeper is damaged or keeper is hit and causes separating from Wooden-door frame, even if at this moment other parts of mechanical lock are excellent is also futile, no matter so be that this crucial potential safety hazard point has all been ignored by large enterprises or small enterprise on present lockset fabrication design, still continue to use the old keeper of tradition, often antitheft emphasis is focused in the research of mechanical lock lock body or tapered end, so the inventor is according to the development Experience of being absorbed in the special-purpose reinforced anti-theft lock of colleges and universities for more than 20 years, through long-felt and test, traditional locks button box is redesigned.

The keeper of wood door lock is all the box body that only has length not long conventionally, then on the projecting plate of box body, open one group of through hole, then keeper is fixed on the side of doorframe, be used for the sealed of door lock, yet install after keeper at the groove of doorframe side, the end face of this doorframe usually only remains 10mm left and right to the wooden thickness between groove surfaces, due to the projecting plate of keeper and the fastening area of groove surfaces little, and fastening through hole again and be listed on a longitudinal straight line, make the groove that this doorframe usually occurs in use procedure to be hit and to split along wood fibre lines, cause doorframe to damage, affect the service life of doorframe, and do not have good anti-theft function yet.

Utility model content

The utility model will solve the shortcoming of above-mentioned prior art, provide in a kind of situation that does not increase doorframe thickness, improve the fastening area of keeper and doorframe fluting end face, avoid the doorframe fluting place to be hit the keeper that rhegma is bad, met school with timber, domestic household for keeper security needs.

The utility model solves the technical scheme that its technical problem adopts: this keeper, the box body that comprises cuboid hollow, between the proximal surface one of lock body and proximal surface two, be provided with inclined plane, on proximal surface one, have for coordinating the rectangular dead bolt hole of dead bolt, on the end face of proximal surface one, be fixed with outward extending projecting plate, on the outer face of projecting plate, riveted joint is fixed with the rectangular plate body that length is greater than projecting plate, riveted joint nail is positioned at the middle part of rectangular plate body, the left and right end of proximal surface one outer face is provided with two and the integrated projection of box body, two projections are spacing to the triangle of rectangular plate body with the common composition of riveted joint nail, projecting plate upper and lower side has two through holes one, on rectangular plate body, have two counterbores one that mate with through hole one position size, the top and the bottom symmetry of rectangular plate body has and is three counterbores two that triangular shape distributes, interleaved setting between counterbore two and counterbore one.The setting of this keeper projecting plate outer face fixed length bar plate body, the fixed-area of keeper and doorframe groove is increased greatly, rectangular plate body on keeper is fixed on projecting plate by one or more riveted joint nails, two projections withstand rectangular plate body, thereby it is spacing that rectangular plate body is carried out to triangular shape, thereby guarantee stable being fixed on rectangular plate body of keeper, and wood screw is by through hole one, when counterbore one and counterbore two are fixed on doorframe groove, further make lock body be fixed on rectangular plate body, also make lock body firmly be fixed on the groove end face of doorframe, between the counterbore one here and counterbore two, interleaved distributes, and while making wood screw be fixed on doorframe groove location, not on a wooden fiber grain, thereby while further preventing that timber from being clashed, doorframe is hit situation about splitting.

Further perfect, the counterbore one of rectangular plate body and counterbore two are the punch forming hole with boss, and the boss of counterbore one is positioned at the hole of through hole one.The boss of this counterbore one is positioned at the setting in through hole one hole, can further make the effect to lock body rotary stopper; Because the top end face of boss is pointed, so wood screw during by counterbore two fastening rectangular plate body, boss top can be partially embedded in doorframe, thus further play to keeper rotary stopper, up and down spacing, left and right is spacing; The chamfering is here conducive to wood screw and mates with it, thereby makes the wood screw head can be outside not exposed, can not affect the keying of door, also can prevent that people from encountering wood screw head and the situation of scratch because of carelessness.

Further perfect, the inner surface of proximal surface one is fixed with two reinforcing ribs, and two reinforcing ribs are arranged near inclined plane and on two jiaos of dead bolt hole.Because timber is in the process being clashed, Door-lock bolt transmits impact and acts on dead bolt hole near the Liang Jiaochu of indoor end face, so add reinforcing rib at dead bolt hole near indoor two jiaos, can further strengthen the crashproof ability of splitting of two jiaos of dead bolt holes, thereby further play, prevent that two jiaos of dead bolt holes from being hit situation about splitting.

Further perfect, the upper and lower side of proximal surface two has the through hole two of a pair of symmetry.Wooden screw is fastened on the end face of doorframe by through hole two, thus fixing keeper further.

Further perfect, the thickness of rectangular plate body is 1.5mm.Rectangular plate body is steel plate material, this set can be conveniently with the punch forming of boss counter sink.

The effect that the utility model is useful is: the utility model structure is utilized the setting of keeper projecting plate outer face fixed length bar plate body, the fixed-area of keeper and doorframe groove is increased greatly, rectangular plate body on keeper is fixed on projecting plate by one or more riveted joint nails, two projections withstand rectangular plate body, thereby it is spacing that rectangular plate body is carried out to triangular shape, thereby guarantee stable being fixed on rectangular plate body of keeper, and wood screw is by through hole one, when counterbore one and counterbore two are fixed on doorframe groove, further make box body be fixed on rectangular plate body, also make box body firmly be fixed on the groove end face of doorframe, and the counterbore of rectangular plate body is the punch forming hole with boss, and the upper and lower side of proximal surface two has a pair of through hole two, further keeper is fixed on doorframe, this keeper has that design is ingenious, reasonable, and cost is low, can be good at the anti-feature such as clash, and is worthy of popularization.
