Description

一种防盗拉头 An anti-theft slider

技术领域 FIELD

本实用新型涉及一种拉链,尤其涉及一种防盗拉头。 The present invention relates to a slide fastener and more particularly to an anti-theft slider.

背景技术 Background technique

现有的拉链,当其应用于公文包、笔记本、箱包之类时,为了防止拉链被打开,有的是把拉链的拉片通过挂锁固定于拉链的一端,这样只有钥匙持有者才能打开挂锁进而拉动拉链;有的箱包为了方便,在拉链上设置两个可以相向运动的拉头,当两个拉头相向运动至某一位置时,两个拉头的拉片共同固定于一密码锁上,这样不知道密码的人就没办法打开箱包。 Conventional slide fastener which, when applied to a briefcase, a laptop, when the luggage and the like, in order to prevent the slide fastener is opened, some of the fastener tab by pad fixed to one end of the fastener, so that only the holder of the key to open the padlock in turn pulls zipper; some bags for convenience, can be disposed on two opposite movement fastener slider, the slider when the two opposite movement to a certain position, two slider pull tab secured to a common cipher lock, and people do not know the password there is no way to open bags. 后者由于设置两个拉头,不仅使生产工艺复杂,成本增加,特别对于小型拉头,把拉片固定于密码锁上特定的位置是很困难的一件事情。 The latter two since the slider, not only the production process is complicated, increasing the cost, especially for small slider, the pull-tab is fixed to a specific position cipher lock is very difficult thing.

发明内容 SUMMARY

本实用新型的目的是提供一种使用方便、成本低廉的防盗拉头。 The object of the present invention is to provide a convenient, inexpensive anti-theft slider.

本实用新型的技术方案是这样的:一种防盗拉头,包括用于使链齿相互啮合或脱开的本体及设于本体上用于锁定或释放本体的密码锁。 Aspect of the present invention is such that: an anti-theft slider, comprising a sprocket for meshing with each other or disengaged from the body and disposed on the body for locking or releasing the lock body.

上述防盗拉头,所述本体内设有用于防止本体自由滑动的自锁簧片,所述密码锁设有一销轴,所述销轴穿越自锁簧片上侧与下侧之间的中空部分。 The above-described anti-theft slider, the body is provided for preventing the locking body slidable spring, the lock is provided with a pin, the pin through the hollow portion of the self-locking spring between the upper and lower sides.

本实用新型通过把密码锁直接设于拉头上并省去拉片等零部件,这样在生产工艺上节省工序和成本,操作时只要转动密码圈至正确位置,即可方便地移动拉链,使用十分方便。 The present invention is provided by the lock directly on the pull tab head and other parts omitted, so that cost savings in the production process and the process, as long as the ring is rotated to the correct password position, the fastener can be easily moved during operation, very convenient.

附图说明 BRIEF DESCRIPTION

图1为实施例应用于笔记本的示意图;图2为实施例的立体图;图3为实施例的立体分解图;具体实施方式本实用新型的设计思想是:把密码锁直接设于拉链的拉头上从而通过密码控制拉头的移动,一方面减少拉头的工艺步骤及零部件,降低成本,同时简化拉头的操作与使用。 FIG 1 is a schematic diagram used in notebook embodiment; FIG. 2 is a perspective view of an embodiment; FIG. 3 is a perspective exploded view of an embodiment; embodiment of the present invention idea is: the lock provided directly on the slide fastener slider so that by controlling the movement of the slider password, while reducing processing steps and parts of the slider, to reduce costs, and simplifies the operation and use of the slider.

参考图1,笔记本1的封面和封底通过拉链2锁闭在一起,拉链2上设有防盗拉头3。 Referring to FIG 1, a notebook cover and back cover 2 together by locking fastener, the slider 3 is provided on the security fastener 2.

参考图2,所述防盗拉头3包括用于使链齿相互啮合或脱开的本体4及设于本体4上用于锁定或释放本体4的密码锁5。 Referring to FIG 2, the slider 3 comprises a body immobilizer for sprockets engaged or disengaged from each other and disposed on the main body 4 of 4 for locking or releasing the lock body 4 5.

参考图3,所述本体4内设有自锁簧片41,所述自锁簧片41包括一体成形的上肋板411与下肋板412,在使用过程中,下肋板412卡设于链条相邻链齿之间防止拉头3自行移动。 Referring to Figure 3, the body 4 is provided with a self-locking spring 41, the spring 41 on the locking plate comprises a rib 411 formed integrally with the lower ribs 412, in use, the ribs provided on the card 412 3 adjacent to the chain to prevent the slider from moving by itself between the fastener. 所述密码锁5包括支架51、设于支架51上的两个密码圈52、弹簧53、锁芯54、销轴55、分别与密码圈52适配并套设于密码圈52与锁芯54之间的密码环56。 The lock 5 includes a support 51, 52 provided on the two rings on the password holder 51, spring 53, cylinder 54, pin 55, ring 52 respectively adapted password and the password provided in the sleeve ring 52 and cylinder 54 password between the ring 56. 整个密码锁5本身作为公知技术,在此只作简单介绍:所述支架51上设有定位槽511,所述本体4上设有与所述定位槽511适配的定位凸台42,所述销轴55穿设于所述定位槽511上,并且所述销轴55中间部分穿设于自锁簧片41上肋板411与下肋板412之间,所述锁芯54下表面抵设于上肋板411上部,这样,当支架51移动时,销轴55跟着移动,从而使得自锁簧片41受到一个向上的推力。 Entire lock 5 itself is a known technique, herein only for brief: a positioning groove 511 on the holder 51, the upper main body 4 is provided with the positioning groove 511 adapted to the positioning boss 42, the pin 55 disposed through the positioning slot 511 and the pin 55 through the intermediate portion 412 disposed between the locking ribs 41 on the spring plate 411 and a lower rib, the lower surface of the cylinder 54 is provided in contact to an upper rib 411, so that, when the carriage 51 moves, the pin 55 moves along, so that the self-locking spring 41 by an upward thrust.

在使用过程中,通过支架51顶部中空部分向下顶动锁芯54下移,转动两个密码圈52设定密码,然后释放锁芯54使其复位。 During use, the top of the hollow portion of the stent 51 by downwardly moving the top down cylinder 54, ring 52 is rotated to set two passwords password, and then release the lock cylinder 54 to reset it. 当拉动拉头至笔记本1两封面处于闭合位置时,转动密码圈52打乱设定的密码,,此时锁芯54抵住自锁簧片41上部,自锁簧片41不能向上移动,拉头3不能在拉链上移动。 When the slider is pulled to a notebook two covers in the closed position, rotation of the ring 52 is disrupted password password setting cylinder 54 at this time ,, the self-locking spring 41 against upper, self-locking spring 41 can not move upward pull head 3 can not move in the fastener. 反之,当转动两密码圈52至设定的密码位置时,锁芯54可以克服弹簧53的弹力推动密码环56向上移动,这样销轴55横向移动能给自锁簧片41一个向上的推力,从而带动下肋板412上移离开链齿,进而拉头3可以自由移动。 On the contrary, when the password positions 52 rotates two turns to set a password, the key cylinder 54 against the force of the spring 53 can push password ring 56 is moved upward, the pin 55 so that lateral movement of the locking spring 41 to give a thrust upwardly, so as to drive the shift plate away from the rib 412 on the sprocket, and thus the slider 3 can move freely.
