Description

The gate lock that contains the tooth bar bolt

Technical field

The utility model relates to a kind of gate lock that contains the tooth bar bolt.

Background technology

In the prior art, the gate lock (Lock for two-wind door) that contains the tooth bar bolt is formed by the inside door handle 1 of the right handles 8 of cylinder lock 9 (containing lock core), outer tapered end 7, the outer tapered end 7 of dress, tooth bar bolt 5, gear 2, transmitting gear 2 and left handle outdoors 3 and as the left tooth bar box 4 and the right tooth bar box 6 of tooth bar bolt 5 passages as depicted in figs. 1 and 2.

From Fig. 1 and Fig. 2 as seen, the outer tapered end 7 of existing gate lock all is mounted on right handles 8 centre bores, and left handle 3 outward appearances that are used for transmitting gear 2 on right handles 8 and other Yishanmen are identical, as cylindrical, taper type, ball-type etc., symmetry is installed, thereby elegant in appearance, as shown in Figure 1.Wherein, the fixed part of outer tapered end 7 is that the tensioned screw 10 that lock body 71 and right handles 8 are all stretched out in door is fixed on the door-plate, as shown in Figure 3.

During use, insert and screw key in the lockhole of tapered end 7 outside, the rotation section of outer tapered end 7 is the just rotatable latch of unblanking of lock core 72, the latch of unblanking is transmitted in a tongue of interior cylinder lock 9, interior cylinder lock 9 tongue is stretched out lock the tooth bar bolt or withdraw the locking of releasing the tooth bar bolt, under the released state of tooth bar bolt, cooperate with tooth bar 5 by inside door handle 1 and left handle 3 transmitting gears 2 again to drive, thereby close the door or opening door operation in the tooth bar bolt.And if lockhole does not insert key, lock core 72 just links to each other with lock body 71, just also is connected with right handles 8.Because right handles 8 is exposed to outside the door-plate, and has only two pieces of primary screws 10 to be strained and fixed, so right handles 8 is easily turned or beat damage by tool holdings such as pipe wrench, sledgehammers.When right handles 8 is firmly clamped when turning by instruments such as pipe wrench, elongated holding screw 10 just may be twisted bending deformation, thereby right handles 8 is rotated.So just may under the situation of not inserting key, can turn right handles 8 and lock core 72, be opened until door with pipe wrench.Therefore, existing gate lock has the danger that is easily turned and open by tool holder such as pipe wrench.

The utility model content

The purpose of this utility model is to provide a kind of gate lock that contains the tooth bar bolt, effectively to avoid outer tapered end by the danger of TOs such as pipe wrench, improves safety.

In order to reach above-mentioned purpose, solution of the present utility model is:

The gate lock that contains the tooth bar bolt comprises the inside door handle of the cylinder lock that contains lock core, outer tapered end, tooth bar bolt, gear, transmitting gear and left handle outdoors and as the left tooth bar box and the right tooth bar box of tooth bar bolt passage; The lock body of outer tapered end directly is inlaid on the door-plate, and the lock core of outer tapered end rotates the latch of unblanking under the drive of key, and the latch of unblanking is transmitted in the tongue of an interior cylinder lock, and flexible the cooperation with the tongue draw-in groove of tooth bar bolt of this tongue locks or release; Inside door handle and the cooperation of left handle turning gear wheel and rack are transmitted in the tooth bar bolt and open the door or close the door.

The described tooth bar bolt gate lock that contains also comprises right handles, and right handles is installed along two fan door centres joint symmetries with left handle outdoors, and outer tapered end is inlaid on the door-plate position by right handles.

The tooth limit of described tooth bar bolt and tongue draw-in groove are respectively formed at the both sides up and down of tooth bar bolt, and simultaneously corresponding cylinder lock, outer tapered end and gear, inside door handle, left handle, right handles also are installed in the both sides up and down of tooth bar bolt respectively.

Described cylinder lock adopts two-way tongue cylinder lock, is installed on the Yishanmen limit, and the tongue of vertical direction cooperates with the tongue draw-in groove of tooth bar bolt and is used to lock the tooth bar bolt, and the tongue of horizontal direction cooperates with draw-in groove on other Yishanmen and is used for directly locking two fan doors.

After adopting such scheme, the utility model directly is embedded in outer tapered end on the door-plate, can only see the end face of outer tapered end in appearance, just as existing many door locks, make externally tapered end assistant destruction of robber like this, guaranteed the anti-theft feature of gate lock, improved safety.

The specific embodiment

As shown in Figure 4, be the preferred embodiment that the utility model provides.

This embodiment contains the gate lock of tooth bar bolt, still comprises the inside door handle 1 of the cylinder lock 9 that contains lock core, outer tapered end 7, tooth bar bolt 5, gear 2, transmitting gear 2 and left handle outdoors 8 as shown in Figure 2 and as the left tooth bar box 4 and the right tooth bar box 6 of tooth bar bolt 5 passages.

In view of outer tapered end 7 is installed in potential safety hazard on the right handles 8, improvement of the present utility model is that outer tapered end 7 is not installed on the right handles 8, but directly be embedded in door-plate on by screw 10 outer tapered end 7, can only see the end face of outer tapered end 7 in appearance, just as existing many door locks, make externally tapered end 7 assistant's destructions of robber like this.

Same as the prior art as for the annexation between other member, do not do at this and to give unnecessary details.Among this embodiment, right handles 8 is directly installed on the door-plate, installs along two fan door centre joint symmetries with

left handle

3, and 8 of right handles play decoration function.And outer tapered end 7 just is installed in around the right handles 8 according to the position needs of cylinder lock 9.At this moment, outer tapered end 7, cylinder lock 9 and gear 2 can be respectively on the both sides up and down of tooth bar bolt 5, also can be with on one side.Such as, gear 2, inside door handle 1, left handle 3, right handles 8 be in tooth bar bolt 5 tops outdoors, and cylinder lock 9 and outer tapered end 7 are below tooth bar bolt 5, therefore, tooth limit on the tooth bar bolt 5 up, and the tongue draw-in groove is down, the opening of left tooth bar box 4 and right tooth bar box 6 also each on one side, (position of partial component cooperates shown in Figure 5) as shown in Figure 4.The also corresponding difference of mounting hole site on the door-plate can only be installed in on one side and have gate lock now simultaneously.The new-type structure of right handles 8, tooth bar bolt 5, and the difference of door-plate mounting hole site, parts installation position have constituted another essential characteristic of the present utility model.

Again as shown in Figure 5 and Figure 6, be another preferred embodiment that the utility model provides.The difference of this embodiment and previous embodiment is: adopt two-way cylinder lock 9 to be installed in the crack between a door and its frame edge, the existing vertical direction of its bi-directional expansion tongue inserts the tongue of tooth bar bolt 5 draw-in grooves, also there is horizontal direction to insert the tongue of the draw-in groove at other Yishanmen edge, as for the label declaration of other member among the figure as hereinbefore, so do not repeat.Like this, when left-hand door is landed latch fixedly the time, right door can also use cylinder lock 9 as single door, and safety is higher.
