Detailed description of the invention
Referring to accompanying drawing, provide the specific embodiment of the present invention, be used for being further described formation of the present invention.
Embodiment 1
The double drag anti-theft locking mechanism of the present embodiment is with reference to figure 1-7, and it is made up of following: main bolt component (Fig. 1), locking plate assembly (Fig. 2), latch assembly (Fig. 3), riveting axle, torsion spring (or extension spring), lock bottom plate 9, locking plate back shaft, locking packing ring.
Main bolt component (Fig. 1) comprises master lock tongue 11, main hyoplastron 12, main hyoplastron pulling axis 13, main tongue shifting axle 14.Main hyoplastron 12 is fixed on master lock tongue 11, main hyoplastron pulling axis 13 is fixed on main hyoplastron 12, can drive lock point motion up and down, main tongue shifting axle 14 is fixed on main hyoplastron 12 and also can moves left and right in the elongated hole of lock bottom plate 9, can promote master lock tongue 11 and move under the effect of mechanism driving power.
Locking plate assembly (Fig. 2) is made up of locking plate body 21 and locking plate riveting axle 22.On locking plate body 21, two elongated groove shaft borehole jacks also can move up and down along it on 2 locking plate back shafts 7, scallop 23 on locking plate body 21 is enclosed within main tongue shifting axle 14, location and latch functions is played when master lock tongue 11 moves, individual earhole 24 is had above locking plate body 21, pulling axis 33 in latch assembly is entangled, drives when locking plate assembly moves up and down latch assembly to move (as Fig. 5, Fig. 6) together.
Latch assembly (Fig. 3) is made up of latch 31, junction plate 32, pulling axis 33, bearing pin 34, and pulling axis 33 is riveting on junction plate 32, and junction plate 32 is assemblied on latch 31 by bearing pin 34, and junction plate 32 can rotate around bearing pin 34.Latch assembly is arranged on base plate can be rotated around riveting axle by latch riveting axle 35, and structure is as illustrated 4.When master lock tongue 11 locking puts that namely main tongue shifting axle 14 moves to the position of left end scallop 22 of locking plate body 21 in place, latch assembly with locking plate assembly in torsion spring 5(or extension spring 6) to move down under effect, main tongue shifting axle 14 locking is completed the locking (as Fig. 5, Fig. 6, Fig. 7) of master lock tongue 11.
Locking plate back shaft 7(2 is only) be riveted on base plate, locking plate body 21 is supported on certain altitude (top of main hyoplastron 11), the motion of locking plate body 21 is play the guiding role simultaneously; Under locking state, when master lock tongue 11 is subject to axial compression, locking plate body 21 also will be subject to equidirectional pressure and this power will be delivered on locking plate back shaft 7, thus stop master lock tongue 11 to bounce back (as Fig. 4, Fig. 5).
Locking plate packing ring 8 is above locking plate body 21 and be enclosed within locking plate back shaft 7, plays control action (as Fig. 5) to locking plate body 21 and the gap of main hyoplastron 11.
The feature one of this anti-theft locking mechanism is in main hyoplastron both sides, by locking plate and latch, locking is carried out to main tongue shifting axle, when master lock tongue bears axial compression, pressure passes on main hyoplastron by master lock tongue, by main hyoplastron, pressure is passed on main tongue shifting axle again, the shearing force that now main tongue shifting axle is subject to is distributed in main hyoplastron and locking plate, on two surface of shear between main hyoplastron and latch, namely main tongue shifting axle shares the shearing effect of axial compression generation by 2 times of sectional areas, and at main hyoplastron both sides stress equalization, the not easily flexural deformation of main hyoplastron, main tongue shifting axle not easy fracture, therefore this anti-theft locking mechanism compressive resistance ability strengthens greatly, it is more than 2 times of common unilateral locking.In sheet metal thickness 3mm stainless steel (or equivalent material), main tongue shifting axle diameter 5mm stainless steel (or equivalent material) situation, master lock tongue axial compressive resistance meets or exceeds 9800N completely.Feature two is that structure is simple, and space hold is few, does not change lock body appearance and size, and reliability is high, making and installation is convenient.
