[0018] 以下所述仅为体现本发明原理的较佳实施例,并不因此而限定本发明的保护范围。 [0018] The following merely embodying the principles of the preferred embodiment of the present invention, without thereby limiting the scope of the present invention.

[0019] 见图1至图3所示:本发明的磁性锁扣由锁紧装置10和定位装置20构成,其中: [0019] Figure 1 to Figure 3: The magnetic latch of the present invention is constituted by the locking means 10 and positioning means 20, wherein:

[0020] 锁紧装置10具有一外壳11,外壳11底部具有一上大下小的钢珠滑槽12,钢珠滑槽12中设有两个钢珠13,外壳11内于钢珠滑槽12的上端设有可与磁块配合的钢珠压块14以及锁紧弹簧15 ;钢珠压块14可在外壳11内滑动,其中部开设有弹簧定位槽141以及定位销导向孔142,钢珠压块14底部对应钢珠滑槽12的位置处成型有锥形凸出部143。 [0020] The locking device 10 has a housing 11, bottom housing 11 has an upper large ball small chute 12, chute 12 ball 13 is provided with two steel balls, steel balls provided at the upper end of the chute 12 within the housing 11 there may be fitted with a steel ball magnet 14 and a locking spring clamps 15; compact steel ball 14 is slidable within the housing 11, wherein the positioning portion defines a spring slot 141 and the positioning guide pin holes 142, 14 corresponding to the bottom of the compact ball ball the chute 12 formed at a position of the tapered projection portion 143. 锁紧弹簧15为锥形弹簧,其上端抵在外壳11的内顶面上,下端抵在弹簧定位槽141的底面上;锁紧弹簧15通过钢珠压块14将钢珠13压紧在钢珠滑槽12内。 15 locking spring is a conical spring, which abuts the upper end in the top surface of the housing 11, the lower end of the spring against the bottom surface of the positioning groove 141; 15 locking spring 14 is pressed against the ball 13 by the ball compact ball chute 12 inside.

[0021] 为了方便锁紧装置10与其它部件的连接和固定,外壳11下端设有连接板16,连接板16周缘可以开设螺纹孔或铆接孔。 [0021] In order to facilitate the member 10 is connected with the other locking device and secured, the lower end of the housing 11 is provided with web 16, web 16 may be a peripheral edge defines a threaded bore or rivet hole.

[0022] 定位装置20包括有定位销21、活动垫片22、定位弹簧23以及固定件24,其中,定位销21前端为可穿过钢珠滑槽12的锁紧段211,锁紧段211中部成型有与钢珠13配合的弧形凹槽212,活动垫片22和定位弹簧23套设在定位销21上,固定件24与定位销21的后端相连。 [0022] The positioning means 20 comprises a positioning pin 21, the movable spacer 22, the positioning spring 23 and the fixing member 24, wherein the distal end of the positioning pin 21 can pass through the ball slide 211 locking portion 12, the central locking portion 211 forming an engaging ball 13 with the arcuate grooves 212, the movable spacer 22 and the positioning spring 23 is sleeved on the positioning pin 21, the fixed member 24 and the rear end of the positioning pin 21 is connected.

[0023] 定位销21于锁紧段211后端成型有定位台阶213,定位台阶213可以对活动垫片22起到限位作用。 [0023] The positioning pin 21 to the rear end of the locking portion 211 formed with a positioning step 213, a stepped positioning stopper 213 can play the role of active pads 22. 另外,定位销21后端为螺纹段214,固定件24为与螺纹段214螺纹配合的锁紧螺母。 Further, the rear end of the positioning pin 21 is a threaded section 214, the fixing member 24 is threaded with the thread segments 214 fit locking nut. 锁紧螺母与定位销21活动连接,不仅可以方便定位弹簧23的安装,而且也可以调节定位弹簧23的松紧度。 Locking nut 21 is movably connected with the positioning pin, not only facilitate the positioning spring 23 is mounted, but also to adjust the tension spring 23 is positioned.

[0024] 本发明的工作原理如下:当定位销21前端的锁紧段211插入钢珠滑槽12中时,锁紧段211顶开两个钢珠13,迫使钢珠13在钢珠滑槽12中向左右两边分开,直到钢珠13卡住锁紧段211中部的弧形凹槽212 ;此时,在锁紧段211插入外壳11的过程中,活动垫片22遇到用于固定锁紧装置10的底板阻挡而使定位弹簧23压缩产生回弹力,回弹力产生使锁紧段211从钢珠滑槽12中退出的趋势,但由于钢珠13受到锁紧弹簧15通过钢珠压块14施加的压紧力,迫使钢珠13卡在弧形凹槽212中无法离开,锁紧段211也就无法从钢珠滑槽12中退出,使得定位销21得以实现自锁和定位。 [0024] The working principle of the present invention is as follows: when the positioning pin 21 is inserted into the distal end of the locking portion 211 when the ball chute 12, the locking portion 211 apart two steel balls 13, forcing the steel ball 13 to the left in the chute 12 ball parted, until the central arcuate groove ball stuck locking portion 13 211212; at this time, the locking portion 211 during insertion of the housing 11, the movable spacer 22 for fixing the face plate 10 of the locking means blocking the positioning spring 23 to compression repulsive force, repulsive force is generated so that the locking portion 211 from the exit chute 12 ball trend, but the steel ball 13 by the pressing force exerted by the 15 compact ball locking spring 14, forcing the steel ball 13 can not leave the card in the arcuate recess 212, the locking section 211 of the ball will not be ejected from the chute 12, so that the positioning pin 21 is self-locking and positioning. 当钢珠压块14受到强磁吸引并且磁力大于锁紧弹簧15的弹力时,钢珠压块14克服锁紧弹簧15的弹力解除对钢珠13的压紧作用,钢珠13离开弧形凹槽212,此时,锁紧段211在定位弹簧23的回弹力作用下从钢珠滑槽12中退出,从而实现锁紧装置10和定位装置20的分离。 When the steel ball 14 by magnetic compact attracted and the magnetic force is greater than the locking force of the spring 15, the ball 14 against the locking spring clamps 15 release the elastic force of the pressing effect on the ball 13, ball 13 away from the arcuate recess 212, this , the locking portion 211 from the ball exit chute 12 is positioned under the resilient action of spring 23, locking means 10 in order to achieve separation and positioning means 20.

[0025] 以上内容仅为本发明的较佳实施例,对于本领域的普通技术人员,依据本发明的思想,在具体实施方式及应用范围上均会有改变之处,本说明书内容不应理解为对本发明的限制。 [0025] The above is only preferred embodiments of the present invention, those of ordinary skill in the art, according to the ideas of the present invention, may make modifications at specific embodiments and application scope, the present specification shall not be as limiting the present invention.
