Description
The utility model relates to a kind of security door lockset, especially a kind of security door lockset with the internal control lock.
The security door lockset of common use generally includes prescription tongue lock and skew bolt lock on the market now, and the dead bolt of wherein square tongue lock is square, the pick-proof better performances, but key switch all must be used in the indoor and outdoor; And skew bolt lock outdoor use key switch, indoor can hand switch, but pushed aside by outdoor sheet instrument easily, so the pick-proof poor-performing.If the user will reach anti-theft effect indoor, when locking skew bolt lock, tongue lock in the side's of locking is used key again when opening simultaneously, and is very inconvenient.For overcoming above-mentioned inconvenience, there is the people to adorn a manual safety bolt in addition in the indoor side of security door, each lockset is not connected as a single entity like this, and anti-theft effect is undesirable, also unfavorable installation, and not attractive in appearance.
The purpose of this utility model provides and a kind ofly both can reach the pick-proof effect, makes things convenient for cubicle switch, is convenient to the security door lockset of three dead bolt one of installation and maintenance simultaneously again.
The utility model is that invention is finished the work like this, a kind of security door lockset with the internal control lock, comprise the square tongue lock and the skew bolt lock that are installed in the housing, it is characterized in that also being provided with in the housing internal control lock, described internal control lock has a manual turning handle, manually turning handle is connected with dead bolt by link gear, and the internal control that can switch has tamper-resistant function without key is locked.
Described link gear comprises fork, stator and hyoplastron, be enclosed within fork on the manual turning handle and press down removable hyoplastron behind the stator, stator is connected by latch segment and hyoplastron, back-moving spring is equipped with in its below, hyoplastron front end riveted joint dead bolt, this structure can guarantee that the internal control lockset has compact structure, and switch is flexible.
The dead bolt of internal control lock is square dead bolt, and manually turning handle is positioned at the lockset inboard, guaranteeing the pick-proof effect of internal control lock, and can't open the internal control lock outdoor.
After adopting this spline structure, an indoor side only need be rotated the manual turning handle of internal control lock can close the internal control lock, reaches the pick-proof effect.And when opening, also only need a counter rotation manual turning handle to get final product, bring convenience to the user.Because the square tongue lock in this security door lockset, skew bolt lock and internal control lock all are installed in the lock housing, thereby make its good looking appearance, the convenient manufacturing and installation.
Further specify the utility model below in conjunction with Figure of description, and provide embodiment.
Fig. 1 is the structural representation of specific embodiment.
Fig. 2 is the wainscot schematic diagram of security door lockset.
As shown in Figure 1, the utlity model has the security door lockset side of the comprising tongue lock (2) of internal control lock, skew bolt lock (3) and internal control lock (4) three parts.Square tongue lock (2) wherein and skew bolt lock (3) are consistent with the structure and the connected mode of common known security door lockset, comprise lock core and dead bolt, shift fork, fixed head, latch segment are housed in the lock core, and the rotation of shift fork drives fixed head and moves up and down, and makes dead bolt flexible to reach locking, to open effect.And the structure of internal control lock and connected mode thereof are set up internal control lock (4) in housing shown in Fig. 1 dashed region, and described internal control lock has a manual turning handle (11), and manually turning handle is connected with dead bolt (10) by link gear.Described link gear comprises fork (6), stator (5) and hyoplastron (8), the fork (6) that is enclosed within on the manual turning handle (11) presses down stator (5) back removable hyoplastron (8), stator (5) is connected by latch segment (7) and hyoplastron (8), back-moving spring (9) is equipped with in its below, hyoplastron (8) front end riveted joint dead bolt (10).Dead bolt (10) is square dead bolt, and manually turning handle (11) is positioned at the lockset inboard.One manual turning handle (11) is arranged on the wainscot of security door lockset as shown in Figure 2, shift fork (6) in the lock is enclosed within on the manual turning handle (11), rotation manual turning handle (11) like this, can drive shift fork (6) rotates, compressing fixed head (5) moves down, shift fork (6) is stirred hyoplastron (8) simultaneously, make dead bolt (10) overhanging, latch segment (7) moves in fixed head (5), when latch segment (7) is corresponding with fixed head (5) upper groove position, because of back-moving spring (9) effect, fixed head (5) sets back, latch segment (7) is stuck in the groove of fixed head (5), makes internal control lock (4) be in locking state, reaches the pick-proof effect.Only need counter rotation manual turning handle (11) during unlatching, driving shift fork (6) rotates, compressing fixed head (5) moves down, and shift fork (6) is stirred hyoplastron (8) simultaneously, makes tongue body (10) retraction, latch segment (7) moves in fixed head (5), when latch segment (7) was corresponding with fixed head (5) upper groove position, because of back-moving spring (9) effect, fixed head (5) set back, latch segment (7) is stuck in the groove of fixed head (5), and internal control lock (4) is in opening.Whole like this process only needs turning handle (11) and does not need key, realizes the unlatching and the locking of indoor anti-theft device.
Certainly, the safe-guard door lock that has internal control lock of the present utility model has also can increase by one group of world lock in the lock housing (1).
