Abstract

The utility model discloses a pulling rope type tool for opening door locks, the anti skid film(4) of which is rectangle; wherein the two long rim of the anti skid film(4) are beset by a safe edge(2) which is provided with at least two fixed heads(3); the one end with a bent arm of the hook shape bracket(6) is hanged with at least two identical elastic rings(1) which are sleeved to the two fixed heads(3) on the safe edge(2) respectively; the inner side of the two safe edge(2) of the anti skid film(4) are respectively pierced by a string(5), and the two ends of the spring are respectively extended from the short rims of the anti skid film(4); and the same end of the strings(5) are bunched together first and then one string(5) is left with an extending section, so as to solve the problem that unlock without a key. The utility mode has advantages that: simple in structure, convenient to be sued, wide in application range, in particular suitable to emergent use door locks with a handle when unlock.

Description

A kind of dragline type lock tool that opens the door

Technical field the utility model relates to a kind of dragline type lock tool that opens the door, and more particularly, relates to a kind of lock tool of putting into from student slit on the appropriate knop that is hung on the door side chain in back that opens the door.

Background technology is not still found the similar dragline type lock tool that opens the door in the prior art.When people are retained in indoor and are eager to enter the room at key loss or key, often force open the door or climb the broken window in building and enter the room, not only dangerous but also inconvenient, even cause unnecessary loss.Thereby need a kind of lock tool that opens the door of alternative key to make emergent need, to separate the matter of great urgency of being eager to open the door.

The summary of the invention the purpose of this utility model is to provide a kind of key simple in structure, easy to use, alternative to make the lock tool that opens the door of emergent need.

In order to achieve the above object, the utility model provides following technical scheme: design a kind of dragline type lock tool that opens the door, this lock tool that opens the door is by rubber band circle (1), safe edge (2), fixing head (3), anti-slide plate (4), cord (5) and support (6) constitute, anti-slide plate (4) is rectangular, two long limits of anti-slide plate (4) stud with strip safe edge (2), be fixed with at least two fixing heads (3) on the safe edge (2), the having of support (6) that is hook-type hangs with at least two pairs of identical rubber band circles (1) on curved boom one end, each rubber band circle (1) is placed in respectively on the fixing head (3) on the correspondence position of two safe edges (2) again, two safe edges (2) inboard of anti-slide plate (4) is respectively worn the two ends that are sewed with a cord (5) and cord (5) and is stretched out from the minor face of anti-slide plate (4) respectively, has at least a cord (5) to have the extension after the same end of two cords (5) is clustered in together respectively.Described rubber band circle (1) preferably uses two pairs, and its intensity and tension force generally can satisfy the needs that open the door; Safe edge (2) the most handy rubber or flexible plastic sheet are made, can be crooked to guarantee it with anti-slide plate (4), with the lock handle in door on hand; Fixing head (3) can be rivet or screw, does not come off thereon as long as rubber band circle (1) is hung; Anti-slide plate (4) preferably weaves with line, and itself and safe edge (2) are sewed up or bonding getting final product; Cord (5) is with nylon rope the best, and its intensity height can not broken, and durable in use; The then the most handy thin round steel of support (6) is made, and has higher intensity, can satisfy the lock that opens the door and use.

The utility model technical scheme preferably can be: the other end that is not connected with anti-slide plate (4) of support (6) has curved boom (7), the shape of curved boom (7) should be able to make things convenient for people's operation, owing to open the door is to rely on support (6) to seek the interior lock handle hand of door, have curved boom (7) and be beneficial to adjusting direction and position, to guarantee to prevent that slide plate (4) accurately places lock handle on hand.

The utility model technical scheme preferably also can be: anti-slide plate (4) is netted film, in general, the net structure surface roughness is big, its frictional force is also big, bending when soft ground then can guarantee to use and the part encases lock handle edge on hand produces bigger frictional force and impels the rotation of lock handle hand so that open the door.

The utility model technical scheme preferably can also be: the end of two extensions of cord (5) respectively links to each other with connecting rod (9) by a connector (8), this mainly is to be convenient to operation, also is convenient to make certainly unlikely being intertwined in extension of cord (5).

Method of operating of the present utility model is: earlier rubber band circle (1) is divided on the curved boom that is placed in support (6), and with support (6) in the position of having measured door lock handle outdoors, put cord (5) and anti-slide plate (4) suitable again, utilize the curved boom of support (6) that cord (5) and anti-slide plate (4) are brought in the door certainly outdoors, utilization will prevent that to measure appropriate position slide plate (4) places circular lock handle on hand, pulling cord (5) is attached on the handle anti-slide plate (4) bag, feel during stay cord anti-slide plate (4) wrapped be attached on the handle after, decontrol support (6), with the hands operate two extensions of cord (5) again, one draws a pine that door handle is rotated and reaches the purpose of opening the door.

Compared with prior art, the utlity model has advantages such as simple in structure, easy to use and applied range.

Be drawing explanation of the present utility model below the description of drawings:

Fig. 1 is a perspective view of the present utility model;

Fig. 2 is the main TV structure schematic diagram in part of the present utility model;

Fig. 3 is a fragmentary top TV structure schematic diagram of the present utility model.

Among the figure: the 1st, rubber band circle, the 2nd, safe edge, the 3rd, fixing head, the 4th, anti-slide plate, the 5th, cord, the 6th, support, the 7th, curved boom, the 8th, connector, the 9th, connecting rod.

By specific embodiment the utility model is carried out more detailed description below the specific embodiment:

With reference to Fig. 1-Fig. 3, open the door lock tool by rubber band circle (1), safe edge (2), fixing head (3), anti-slide plate (4), cord (5) and support (6) constitute, anti-slide plate (4) is rectangular, two long limits of anti-slide plate (4) stud with strip safe edge (2), be fixed with four fixing heads (3) on the safe edge (2), the having of support (6) that is hook-type hangs with two pairs of identical rubber band circles (1) on curved boom one end, each rubber band circle (1) is placed in respectively on the fixing head (3) on the position correspondence of two safe edges (2) again, two safe edges (2) inboard of anti-slide plate (4) is respectively worn the two ends that are sewed with a cord (5) and cord (5) and is stretched out from the minor face of anti-slide plate (4) respectively, has a cord (5) to have the extension after the same end of two cords (5) is clustered in together respectively.

With reference to Fig. 1 and Fig. 3, anti-slide plate (4) is netted film.

With reference to Fig. 1, the other end that is not connected with anti-slide plate (4) of support (6) has curved boom (7), and this curved boom has flat ring; The end of two extensions of cord (5) respectively links to each other with connecting rod (9) by a cyclic adapting piece (8).
