Description

Has the panel of lock that protects lock function

[technical field]

The utility model relates to a kind of panel of lock that is used on the security door, and specifically a kind of have a panel of lock that protects lock function.

[background technology]

Lockset on the security door plays very important effect on anti-theft feature, the good ring of lockset directly has influence on the use of security door.The theftproof lock that now is installed on the security door is of a great variety, but all has a common shortcoming: can see lockhole from being positioned in the tapered end hole (key passes this hole and inserts lockhole, to open lockset) on the panel of lock.Some people understands mischief ground and fill in foreign material (as chewing gum, glue, toothpick etc.) in lockhole; children also can do similar action unintentionally sometimes; and existing panel of lock does not have the lock function of protecting, and can't protect lockhole, has caused very burden to daily life.

[utility model content]

Technical problem to be solved in the utility model is the defective that overcomes above-mentioned prior art, a kind of panel of lock that protects lock function that has is provided, it effectively the back side in tapered end hole is covered and locking covers this state, to prevent to be filled in the lockhole generation of foreign material phenomenon, further improve the security performance of lockset.

The technical solution of the utility model is such: have the panel of lock that protects lock function, comprise panel and the tapered end hole that is located on the panel, it is characterized in that top, described tapered end hole is provided with a push button, have one on the panel and be used for the slotted eye that push button moves, panel inner wall is provided with a shutter that is connected with push button, this shutter is provided with a through hole that can communicate with the tapered end hole, and the below in tapered end hole is provided with one can be with the coded lock of shutter lower end locking.When push button was in the upper end of slotted eye, the through hole on the shutter communicated with the tapered end hole, did not influence the normal use of lock, and the lower end of shutter and coded lock break away from; When push button is in the lower end of slotted eye, through hole on the shutter and the dislocation of tapered end hole, shutter covers the back side in tapered end hole, the lower end of shutter is pinned by coded lock, can't see lockhole from the tapered end hole, lock also can't use, thereby has prevented in the lockhole by the generation of plug foreign material phenomenon.

Described have a panel of lock that protects lock function, coded lock is a mechanical type, it comprises the top rotary table seat that is installed on the panel inner wall, be enclosed within the top rotary table on the top rotary table seat, by top rotary table lower rotary table that covers and the knob that is located on the panel outer wall, be provided with ball and stage clip between this knob and panel, knob, lower rotary table and one is positioned at, double-action plate three between lower rotary table is fixed together, the lower end of shutter is provided with, the lower rotary table latch, on, the outer rim of lower rotary table all is provided with the perpendicular chimb of a circle, on, have the top rotary table breach that is used for top rotary table latch turnover and the lower rotary table breach of lower rotary table latch turnover on the chimb of lower rotary table, have on the top rotary table and be used for " C " shape groove that double-action plate rotates.This rotating disc type coded lock is provided with two road passwords.The process of unblanking of shutter is as follows: the Rotary puzzle lock knob, knob drives double-action plate and lower rotary table rotates together, double-action plate rotates in " C " of top rotary table shape groove, will drive top rotary table when forwarding the groove end to rotates, when the top rotary table breach is in the top rotary table latch place of shutter lower end, one password opened, and there is corresponding numeral this position on the dial of knob; The opposite spin knob, knob drives double-action plate and lower rotary table rotates together, double-action plate rotates in " C " of top rotary table shape groove, double-action plate idle running, can not drive top rotary table rotates, when lower rotary table indentation, there during in the lower rotary table latch place of shutter lower end, another road password is also opened, and also there is corresponding numeral this position on the dial of knob.It is very simple that shutter is locked, and only needs positive and negative several lower knobs that revolve, and the chimb that makes the Rolling disc lock stops be positioned at rotating disk gets final product.

Described have a panel of lock that protects lock function, the push button lower end is provided with lamp holder display lamp down, be evenly equipped with tooth on the chimb of lower rotary table, lower rotary table is provided with the microswitch of control display lamp outward, fine motion sheet middle part on the microswitch outwards convexes into an arc protuberance, and the arc groove that forms between this arc protuberance and the adjacent teeth coincide.As long as lower rotary table one rotates, the microswitch action, display lamp is bright, and the lamp holder of display lamp both can illuminate the outside in tapered end hole down, also can illuminate the dial of knob, makes things convenient for and opens theftproof lock and coded lock evening.

Described have a panel of lock that protects lock function, panel inner wall is provided with reference column, folding shape limiting plate is arranged on this reference column, be provided with spring between limiting plate and the shutter, utilize the elastic force of spring to make the upper and lower end position location of shutter in slotted eye, limiting plate is provided with the tapered end location-plate outward, and the tapered end locating hole is arranged on the tapered end location-plate, in order to the fixing tapered end of lockset.

Described have a panel of lock that protects lock function, and panel is provided with handle, the unlatching of convenient and theftproof door.

The utility model covers the back side in tapered end hole with shutter and will cover this state locking with coded lock, has prevented in the lockhole by the generation of plug foreign material phenomenon; The setting of display lamp makes and opens theftproof lock and coded lock convenience evening; Two road passwords are set on the coded lock makes the locking of shutter safer; During unlocking tool, need earlier coded lock to be removed, prolonged uncaging time, further improved the security performance of lockset.

The utility model is described in further detail below in conjunction with drawings and Examples.
