To make the objectives, technical solutions, and advantages of the present invention more comprehensible, below will be by specific embodiment and relevant drawings, invention is further described in detail.
As shown in Figure 1, Figure 2 and Figure 3, Fig. 1-3 is a kind of device with door lock assembly provided in this embodiment, and Fig. 1 is the perspective view of the device, and Fig. 2 is the main view of the device, and Fig. 3 is the left view of the device.The device can be communication equipment such as optical fiber terminal box, be also possible to the different citing of containing case, stationery cabinet, safety cabinet etc..The device includes first panel 1 and second panel 2, if device is the device of side opening, first panel 1 can be doorframe or cabinet body, and second panel 2 is door-plate.If device is top surface open container, first panel 1 is also possible to container side frame, and second panel 2 is lid, and the above is only for example, not as concrete restriction.Certainly, first panel 1 and second panel 2 also can be interchanged, and first panel 1 is door-plate or lid, and second panel 2 can be doorframe or cabinet body or side frame.Only facilitate description using first panel 1 and second panel 2 in the present embodiment, emphasize that a part of door lock assembly is mounted in first panel 1, another part of door lock assembly 3 is mounted in second panel 2, it locks and separates by door lock assembly 3 between first panel 1 and second panel 2, in other embodiments, first panel 1 and second panel 2 may also be only the fixed point of the fixed door lock assembly 3.With setting, there are two door lock assemblies 3 to illustrate on device in FIG. 1 to FIG. 3, and not the limitation explanation of embodiment, particular number are arranged according to the actual situation.
Lower mask body introduces door lock assembly 3.
As shown in Fig. 3 to Fig. 7, which includes the lock core 31 on the clamping part 32 and second panel 2 being fixed in first panel 1.As shown in Figure 6 and Figure 7, wherein lock core 31 includes axis body 310 and is arranged in 310 one end of axis body
Guide head 311, guide head 311 and 310 junction of axis body are provided with the first recessed portion 312.Preferably, guide head 311 is one of prismoid, pyramid, cone in the present embodiment.It Fig. 6, in 7 is schematically illustrate with pyramid, guiding surface on pyramid is preferentially set as even number, and so symmetrically arranged purpose of even number is lock core 31 is relatively easy to mode by the guidance of guide head 311 to be inserted into clamping part 32 to realize that lock core 31 is locked with clamping part 32.
As shown in Figure 8 and Figure 9, clamping part 32 includes pedestal 321 and buckle 322, the first through hole 3210 passed through for axis body 310 and guide head 311 is provided on pedestal 321, buckle 322 with the first recessed portion 312 on lock core 31 for engaging.Guide head 311 and axis body 310 pass through the first through hole 3210 on the pedestal 321 of clamping part 32 and buckle 322 latches so that first panel 1 and second panel 2 are locked.Guide head 311 and axis body 310 and buckle 322 are detached from by external force, so that first panel 1 and second panel 2 are detached from.Buckle 322 further comprises the first elastic arm 3221 and the second elastic arm 3222 in the present embodiment, and the first elastic arm 3221 and 3222 arc of the second elastic arm are fixed on the same side of pedestal 321.Preferably, the first elastic arm 3221 and the second elastic arm 3222 are symmetrical arranged.The gap of predetermined width is formed between first elastic arm 3221 and the end of the second elasticity 3222.It is aligned in order to facilitate lock core 31 with buckle 322, lock core 31 can smoothly be inserted into lock core 322, and the gap and first through hole 3210 between the first elastic arm 3221 and the second elastic arm 3222 are in the same plane.
As shown in Figure 6 and Figure 7, the first recessed portion 312 further comprises the first inclined surface 3120 and the second inclined surface 3121, and the first inclined surface 3120 and the second inclined surface 3121 facilitate to form the first recessed portion 312 with guide head 311.Preferably, the first inclined surface 3120 and the second inclined surface 3121 are symmetrical arranged.
When the insertion of guide head 311 buckle 322 of lock core 31, guide head 311 makes the first elastic arm 3221 and outer of 3222 elasticity of the second elastic arm, when equal guide heads 311 exceed gap, the first elastic arm 3221 and the second elastic arm 3222, which restore elasticity, to be clamped the first recessed portion and clamps the first inclined surface 3120 and the second inclined surface 3121.Be combineding with each other for guide head 311 and open first elastic arm 3221 and the second elastic arm 3222, forms torque at closing time, turns without key, the automatically lock of first panel 1 and second panel 2 can be realized.When lock core 31 and buckle 322 are detached from, when lock core 31 rotates to certain angle, due to except the first inclined surface 3120 and the second inclined surface 3121 part guide head 311 and axis body 310 there is no the settings of recess, be slightly easy to by external force lock core 31 when disengaging and the first elastic arm 3221 and the second elastic arm 3222 be smoothly detached from.
As shown in figure Fig. 4, Fig. 5 and Fig. 8, it is provided with the second through-hole 11 for accommodating the second recessed portion 10 of lock core 31 and passing through for lock core 31 in second panel 2, the limiting slot 100 for limiting 31 rotational angle size of lock core is provided on the second recessed portion 10.Limiting slot 100 is corresponded on the axis body 310 of lock core 31 and is provided at least one limited block 313, and limited block 313 can be a protrusion.When lock core 31 rotates in second recessed portion 10, limited block 313 rotates in limiting slot 100, and lock core 31 and second panel 2 realize the limitation of unlocking angle by limited block 313 and limiting slot 100.Also corresponding second recessed portion 10 is provided with supporting surface 314 on the axis body 310 of lock core 31, it is preferred that the supporting surface 314 is vertical with axis body 310 fixed.It should be noted that supporting surface 314 and axis body 310 can also can be realized otherwise with integrated molding.
Further, in another embodiment, door lock assembly 3 further includes for the circlip 33 that lock core 31 and second panel 2 is fixed, and the length or diameter of circlip 33 are conducive to lock core 31 when circlip 33 blocks lock core 31 in this way and are not detached from second panel 2 more preferably greater than the diameter of the second through-hole 11.Circlip 33, which is corresponded to, on the axis body 310 of lock core 31 is provided with third recessed portion 315.When lock core 31 is placed in the second recessed portion 10, third recessed portion 315 is stuck in by circlip 33, lock core 31 is fixed in second panel 2.While the elastic characteristic of circlip 33 is in addition to playing lock core 31 and fixed second panel 2, also retain the function that lock core 31 can be freely rotated in the second recessed portion 10.
As shown in Figure 9 and Figure 10, the outer surface of supporting surface 314 is provided with the unlocking portion 316 of preset shape, is illustrated in figure with common triangle.Preferably, for design for aesthetic, the thickness in supporting surface 314 and unlocking portion 316 adds up the depth no more than the second recessed portion, so that the top in unlocking portion 316 is not above second panel 2.In the present embodiment, it can be used with phase
Key twisting unlocking portion 316 with preset shape groove is rotated with movable lock core, realizes the disengaging of first panel 1 and second panel 2.
Lock core 31 is inserted into clamping part 32 by the guidance of guide head 311 and realizes that lock core 31 is locked with clamping part 32 by door lock assembly disclosed by the embodiments of the present invention.Guide head 311 and axis body 310 and buckle 322 can be slightly detached from by external force when disengaging, so that first panel 1 and second panel 2 are detached from.The door lock assembly part is few, and assembly is simple, at low cost, practical.
Obviously, those skilled in the art can carry out various modification and variations without departing from spirit and scope to the application.If then the application is also intended to include these modifications and variations in this way, these modifications and variations of the application belong within the scope of the claim of this application and its equivalent technologies.
