Detailed description of the invention

As it is shown in figure 1, high-test chain lock includes lock body 2 and the chain body 1 being formed by connecting that interlocked by multiple beckets. Described lock body 2 includes lock core assembly 201, stop 202 and lock body shell 203, and lock core assembly 201 can select in prior art various The lock core of type, such as lock cylinder, blade lock core, described lock core assembly 201 includes the lock core shell 2011 of tubular and cylinder Lock core 2012, described lock core 2012 can be rotatably set in lock core shell 2011, have employed blade lock core in this specific embodiment Assembly.

As illustrated in figs. 2-7, described chain body 1 one end is fixedly connected on lock body 2, and described lock core assembly 201 is arranged on In lock body shell 203, described lock body shell 203 is one section of high-strength tubular hardware, and lock body shell 203 endoporus is circular hole, described chain Bar body 1 one end is fixedly connected on one end of described lock body shell 203, and described lock core assembly 201 is arranged on lock body shell 203 other end Inner chamber in, the middle part tube wall of described lock body shell 203 is provided with opening with described becket axis projection matching form and constitutes Lockhole 2031, described lockhole 2031 direction makes the becket place plane inserted parallel with described lock body shell 203 central shaft, Described stop 202 is arc tabular component, and the center of arc preferably overlaps with stop 202 center of rotation, width and becket Endoporus matched in clearance, described stop 202 is circumferentially disposed in lock body shell 203 inner chamber, and described stop 202 is in lock body shell 203 Axial location fix and corresponding with lockhole 2031 center, described stop 202 circumference be connected with lock core 2012.

In this specific embodiment, as shown in fig.7-12, described lock body shell 203 selects metal circular tube, in order to ensure have enough Mechanical strength, lock body shell 203 to have enough thickness, described lock body shell 203 one end endoporus is provided with columnar metal lock lining 3, The outboard end of lock lining 3 is provided with axial notch 301, and the becket of described chain body 1 one end is inserted in wherein, and it is same to be provided with lateral pin 4 Time through becket endoporus, lock lining 3 and lock body shell 203 both sides tube wall, one end of chain body 1 and lock lining 3 are fixed on lock body shell On 203, described lock core assembly 201 is arranged in the inner chamber of lock body shell 203 other end.

Described stop 202 is arc tabular component, and stop 202 uses arc tabular to be disposed to when stop 202 is at lock When rotating under the drive of core 2012, stop 202 will not be beated in position radially, and stop 202 works relatively reliable, because of This, stop 202 can be arranged on any revolving part being connected with lock core 2012, and is preferably wholely set.
