Description
Technical field
The utility model relates to a kind of drawing and pulling type snap close, is specifically related to a kind of quick drawing and pulling type snap close, especially a kind of quick drawing and pulling type snap close that connects multiple spot.
Background technology
The existing snap close that shirks fast mainly contains push button, insert-type and dragline type.
The push button disconnecting means is common in the use of car seat safety belt, as: CN202445256U discloses a kind of push button buckle of safety belt, it comprises bracelet body snap close, snap close is built-in with and inserts mouth, with an insertion mouthful adjacent unlock button, bracelet body snap close is fixed on the automotive seat next door by the connector of bottom, and the driver can be by button rapidly with the safety belt lock catch release.This device is main to rely on the interaction of button and snap close to realize shirking, and device is comparatively complicated, and when the driver touched button because of carelessness, safety belt will be opened, and security is lower.
The insert-type release unit is common in the knapsack connecting band, as: CN 2285978Y discloses a kind of insert-type bracelet, it comprises a pin thread and a box, the button tongue of pin thread is provided with a button hole, box is by a button casket, one buckle and a back-moving spring that is provided with tenon formed, form an opening between the button casket of box and buckle, in the button tongue of pin thread inserts the opening that forms between the button casket of box and buckle, the tenon of box buckle bottom surface is namely detained in the button hole that snaps in pin thread button tongue, pin thread and box are fastened mutually, as long as suitably pull the free end of box buckle in the other direction towards the base plate of box button casket, the tenon of this buckle bottom surface namely outwards shifts out in the button hole of pin thread button tongue, and the pin thread of fastening and box can be pulled and untie.This device is main to rely on the interaction of pin thread and box to realize shirking, and device is also comparatively complicated, and has wearing and tearing after repeatedly using, and causes the conformability of pin thread and box to reduce, and in case of emergency may occur at short notice and can't shirk.
The dragline type release unit then is common in being fastenedly connected of hood for motor car lid, as: CN201056157Y discloses a kind of stay cord and has connected, specifically disclose and be provided with stay cord in the tarpaulin, the two ends of stay cord are separately fixed at the front and back end of tarpaulin, the top of tarpaulin has the rope mouth, the part stay cord passes from the rope mouth, and the stay cord that passes part is provided with the pulling part, is convenient to receive fast whole Peng Gai.Though this device simplicity of design, because stay cord is easy to take place deformation under external force, and two ends are fixed, and are difficult at short notice shirk.
In sum, for push button and insert-type drawing and pulling type snap close, mechanism's volume is all bigger, and structure is comparatively complicated, and each device all only connects a tie point, is difficult to free simultaneously a plurality of tie points.For the dragline type jockey, can adopt a rope that a plurality of tie points are together in series, but because the rope softness is yielding under external force, all be bundled on the fixed position so shirk the two ends of rope, so in emergency circumstances still be difficult to realize fast freeing.
