Embodiment
[first embodiment]
Figure 1A is the constitutional diagram according to the locking structure of first embodiment of the invention, and Figure 1B is the exploded view according to the locking structure of first embodiment of the invention.Fig. 1 C is the enlarged diagram of screw among Figure 1B.Please refer to Figure 1A to Fig. 1 C, the locking structure 100 of present embodiment comprises first assembly 110, second assembly 120 and screw 130, and wherein first assembly 110 and second assembly 120 can be casing, component, electronic component or other workpiece that need mutually combine.In addition, second assembly 120 is disposed on first assembly 110, and wherein first assembly 110 has the first screw 110a.Second assembly 120 comprises the body 122 and first clamping part 124, and wherein body 122 has the second screw 122a, and first clamping part 124 can be to be positioned at by the second screw 122a.In addition, screw 130 is in order to first assembly 110 and second assembly 120 of locking, and screw 130 comprises head 132 and the screw spindle part 134 that is connected to head 132.Head 132 has at least one second clamping part 132a.When screw 130 screwed in first assemblies 110 and second assembly 120, screw spindle part 134 was locked in the second screw 122a and the first screw 110a, and the second clamping part 132a and first clamping part 124 are interlocked.
For example, first clamping part 124 can be a perforation, and the second clamping part 132a can be a lug boss.When screw 130 screwed in first assembly 110 and second assembly 120 gradually, the second clamping part 132a can contact with second assembly 120 earlier.At this moment, if continue rotary screw 130, then will embed in the perforation as first clamping part 124 as the lug boss of the second clamping part 132a.Owing to be interlocked as the lug boss of the second clamping part 132a and perforation as first clamping part 124, therefore when this locking structure 100 be given a shock or the situation of impacting under, screw 130 more difficult disengaging first assembly 110 and second assemblies 120.In addition, whether the user can by being interlocked between the second clamping part 132a and first clamping part 124, to avoid screw 130 excessive screwing are damaged the screw thread in first assembly 110 and second assembly 120.
It should be noted that the first screw 110a can be perforation or blind hole.In addition, though the head 132 of screw 130 has cross recess, present embodiment does not limit the kenel of head 132.For example, head 132 also can be to have a word groove.Similarly, the screw spindle part 134 of present embodiment is cylindric, but screw spindle part 134 also can be coniform.In addition, present embodiment does not limit the shape and the pitch of the screw thread on the screw spindle part 134.
In the present embodiment, first clamping part 124 also can have different designs with the second clamping part 132a, so that reach the structure of phase embedding.For example, will become groove as the perforation of first clamping part 124.Perhaps, will become lug boss as the perforation of first clamping part 124, and become groove as the lug boss of the second clamping part 132a.In addition, present embodiment does not also limit allocation position, shape and the quantity of first clamping part 124 and the second clamping part 132a.In addition, the material of first assembly 110 and second assembly 120 can be metal or plastics, and the material of screw 130 can be metal, plastics or plastics.
[second embodiment]
Fig. 2 A is the exploded view according to the locking structure of second embodiment of the invention, and Fig. 2 B is the enlarged diagram of screw among Fig. 2 A.Please refer to Fig. 2 A and Fig. 2 B, present embodiment is similar to the aforementioned embodiment, both are difference: in the locking structure 200 of present embodiment, first clamping part 212 of second assembly 210 is a lug boss, and the second clamping part 222a of head 222 can be groove 222b and the guide slot 222c that is connected to groove 222b, so when DRIVE SCREWS 220, can be in guide slot 222c slip and embedding groove 222b as the lug boss of first clamping part 212.
In another embodiment, first clamping part 212 also can become the combination of perforation and guide slot, and the second clamping part 222a becomes lug boss.Perhaps, first clamping part 212 also can become the combination of groove and guide slot, and the second clamping part 222a becomes lug boss.
[the 3rd embodiment]
Fig. 3 A is the exploded view according to the locking structure of third embodiment of the invention.Fig. 3 B is the enlarged diagram of screw among Fig. 3 A, and Fig. 3 C is the enlarged diagram of second assembly among Fig. 3 A.Please refer to Fig. 3 A to 3C, present embodiment is similar to the aforementioned embodiment, both are difference: in the locking structure 300 of present embodiment, first clamping part 312 of second assembly 310 is a cantilever, and first clamping part 312 has perforation 312a, therefore when DRIVE SCREWS 130, understand cantilever first and as the lug boss of the second clamping part 132a and contact, and make the axis direction skew of clamping part 312 of winning along screw spindle part 134 as first clamping part 312.At this moment, if continue rotary screw 130, then the lug boss of the second clamping part 132a will embed among the perforation 312a.
It should be noted that since cantilever have elasticity, so this locking structure 300 be given a shock or the situation of impacting under, screw 130 more difficult disengaging first assembly 110 and second assemblies 310.In addition, can be thickness as the thickness of the cantilever of first clamping part 312 less than body 122.Similarly, in the present embodiment, perforation 312a also can become groove.In another embodiment, also can become groove as the lug boss of the second clamping part 132a, and perforation 312a also becomes lug boss.
In sum, the present invention's locking structure has following advantage:
One, compare with known technology, the present invention be given a shock or the situation of impacting under, more difficult disengaging first assembly of screw and second assembly.
Two, by learning that whether second clamping part and first clamping part are interlocked, the user can avoid the screw excessive screwing.
Though the present invention discloses as above with preferred embodiment; right its is not in order to limit the present invention; any person of ordinary skill in the field; without departing from the spirit and scope of the invention; when can doing a little change and improvement, so the present invention's protection domain attached claim person of defining after looking is as the criterion.
