Abstract

The utility model discloses a lock hole barrier structure mounted on an anti-theft lock. The existing lockset panel with lock-protecting function is equipped with a coded lock and a lock hole barrier plate which is engaged and used with the coded lock, the locking-hole barrier plate can avoid the lock hole being blocked by sundries, but because the structure of the lock hole barrier plate is complex in structure and inconvenient in assembly, and can not automatically return after being used, the lockset panel with lock protecting function is inconvenient in use. The lock hole barrier structure comprises a lining bottom plate, and is characterized in that the lining bottom plate is equipped with an upper barrier sheet and a lower barrier sheet which slide on the lining bottom plate, the upper barrier sheet and the lower barrier sheet are arranged symmetrically, springs are arranged between the upper portion of the upper barrier sheet and the lining bottom plate and between the lower portion of the lower barrier sheet and the lining bottom plate, the lining bottom plate is equipped with a key locating hole, and when the upper barrier sheet and the lower barrier sheet are closed, a key inserting groove which is located outside the key locating hole is formed. The utility model utilizes double barrier sheets which can barrier the lock hole under a normal state, thereby avoiding the lock hole being blocked by the sundries, and further, the utility model can automatically return after being used and is convenient in use.

Description

The lockhole barrier structure

Technical field

The utility model relates to the accessory of theftproof lock, specifically a kind of lockhole barrier structure that is installed on the theftproof lock.

Background technology

Theftproof lock plays very important effect on anti-theft feature, the good ring of lockset directly has influence on the quality of security door.The existing theftproof lock that is installed on the security door is of a great variety, but all have a common defective mostly: (key inserts lockhole to the lockhole of theftproof lock, to open lockset) be exposed, some people understands mischief ground and fill in foreign material (as chewing gum, glue, toothpick etc.) in lockhole, children also can have no desire to do similar action sometimes, have caused very burden to daily life.The panel of lock that a kind of band protects lock function appears at present, which is provided with coded lock and the lockhole shutter that is mated use, come being used to block the shutter realization lock and unlock of lockhole by coded lock, thereby can avoid in the lockhole by the generation of plug foreign material phenomenon, improved the security performance of lockset, but its complex structure can not automatically reset after assembling inconvenience and the use, uses inconvenient.

The utility model content

Technical problem to be solved in the utility model is to overcome the defective that above-mentioned prior art exists, provide a kind of simple in structure and use after can automatically reset lockhole barrier structure, with convenient for assembly and use.

For this reason, the utility model adopts following technical scheme: the lockhole barrier structure, comprise interior underboarding, it is characterized in that described interior underboarding is provided with upper stop piece and the lower stop piece that slides thereon, described upper and lower catch is and is symmetrical arranged, and the top of upper stop piece, the bottom of lower stop piece are provided with spring respectively and between the interior underboarding; Interior underboarding is provided with the key positioner hole, and formation one was positioned at the key slot in the outside, key positioner hole when upper and lower catch was closed.Under the normality, two catch are in the auto-closing state under the effect of spring, and catch blocks the key positioner hole, and the key positioner hole is corresponding with the position of lockhole, thereby have avoided in the lockhole by the generation of plug foreign material phenomenon.During use, key slot place inserts key, and spring is compressed, and upper and lower catch is opened automatically, and upper stop piece moves upward, and lower stop piece moves downward, and key passes in the key positioner hole insertion lockhole then, thereby lockset is opened.When key when lockhole takes out, two catch are auto-closing under the effect of spring.

As the further of technique scheme improved and replenish, the utility model is taked following technical measures:

Above-mentioned lockhole barrier structure has chute on the interior underboarding, and the back side of catch is provided with the slide block that slides in chute, utilizes slide block and cooperating of chute to realize sliding up and down of catch, and slide block and chute can be for one or more.

Above-mentioned lockhole barrier structure, the back side of catch are provided with at least one pair of and are symmetrically arranged buckle, and buckle is connected on the interior underboarding, buckle is used for catch is positioned at interior underboarding, do not influence sliding up and down of catch, during the catch running, buckle also operates with catch.

Above-mentioned lockhole barrier structure, catch are metal washer or plastics catch, and the center of the key slot of plastics catch is embedded with a sheet metal, and sheet metal is used to strengthen abrasion resistance.

Above-mentioned lockhole barrier structure, the shape of key slot is consistent with the shape in key positioner hole; The shape of cross section of key slot is V-shaped, the insertion of Key.

Above-mentioned lockhole barrier structure, the key slot is made of upper and lower two parts of symmetry, is located at respectively on the upper and lower catch.During the catch auto-closing, the key slot is complete; When catch was opened, the key slot was divided into upper and lower two parts.

The utility model utilizes two catch of energy auto-closing under the normality to block lockhole, has avoided lockhole to be filled in the generation of foreign material phenomenon; Can automatically reset after the use, easy to use; Simple in structure, easy to assembly, improved production efficiency, also reduced cost of production.

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
