The specific embodiment
The invention will be further described below in conjunction with accompanying drawing:
Extremely shown in Figure 5 by Fig. 1, the embodiment of a kind of tapered end of the present invention, include outer tube 1, in outer tube 1, be provided with the lock core 5 with the coaxial setting of outer tube 1, at outer tube 1, radially be provided with lockhole 11, in lockhole 11, be provided with spring 8 and send son 7, the front end of described lock core 5 is provided with rotating disk 3, between one end of rotating disk 3 and the rotating shaft 51 of lock core 5, be provided with and can make after the two relative rotating to an angle the syndeton of synchronous rotary again, at rotating disk 3 other ends, be provided with stop sheet 21, between rotating disk 3 and lock core 5, also be provided with and can order about the torsion spring 4 of rotating disk 3 to the locking direction rotation, the described son 7 that send has with stop sheet 21 clamping matching to stop stop sheet 21 with overcoming spring 8 active forces, move down and with stop sheet 21, separate the second place that stop sheet 21 is rotated to locking direction to the primary importance of locking direction rotation.Even the lock in the present invention is in opening, owing to sending son 7 to move (namely being in primary importance) under the resetting of spring 8, stop sheet 21 is blocked to the active force that makes rotating disk 3 overcome torsion spring 4 and can not rotate, can lock core rotating shaft 51 be rotated to lock-out state with key 6 like this, that is to say due to lock core turn 51 with the specific syndeton of rotating disk 3, while making lock core rotating shaft 51 be in the lock state, stop sheet 21 still is in lockset position of coupler, so just can take off key 6.When inserting the interior son 7 that will send of lockhole 11, locking bar 9 presses down (sending son 7 to be in the second place), send son 7 no longer to block stop sheet 21, under the active force of torsion spring 4, rotating disk 3 drives stop sheets 21 and rotates the interior realization of locked groove 91 that namely can insert locking bar 9 to latched position and automatically lock without key, thereby has improved the convenience of using.
Above said lock core rotating shaft 51 and the specific syndeton of rotating disk 3, specific to structure, be have very multimode, such as the structure adopted as shown in Fig. 1,2, namely on the end face axle center of rotating shaft 51, be provided with flat side's boss 511, on the end face of rotating disk 3, be provided with the shrinkage pool coaxial with rotating disk 31, the circumferential wall of shrinkage pool 31 is provided with axisymmetric two stopper protrusions 311, and the flat side's boss 511 in rotating shaft 51 is inserted in the described syndeton of the interior formation of shrinkage pool 31 of rotating disk 3.Can certainly in rotating shaft, establish the projection of 1/4 circle, then on rotating disk, establishing semicircle orifice or 3/4 circular hole (arranging according to the difference of the two relative rotation angle) realizes connecting, by in rotating shaft, establishing radial peg, on rotating disk, establish radially annular groove, by radial peg and annular groove radially, realized connecting; Perhaps also can stretch out at the end face of rotating shaft one or two eccentric projection, realize connecting and establish non-full circle annular groove at the end face of rotating disk; And the various ways that much no longer exemplify in addition.But adopt illustrated structure, the one, bonding strength is better, and the 2nd, structure is also relatively simple, is therefore to be preferred mode.
As shown in the figure, described stop sheet 21 one are located on stop 2, stop 2 is fixedly connected with rotating disk 3, described stop 2 and stop sheet 21 are steel (can certainly adopt the material that other relative intensity is higher), and described rotating disk 3 is zinc alloy material (can certainly adopt other can cross the produced material of die casting mode).By stop and rotating disk split are arranged, adopt stop and stop sheet steel to make like this, stop sheet intensity is high like this, wear-resistant, longer service life while being used in conjunction with locking bar, and rotating disk is adopted to zinc alloy material, rotating disk can be made by the die casting mode like this, even the structure more complicated of rotating disk like this, the mode by die casting also can conveniently create.And if rotating disk also adopts steel, obviously processing is just very difficult, is so also disadvantageous.But even the stop sheet adopts and the mode of rotating disk one, this remains and belongs within protection domain of the present invention.
