The locking device 100 includes the button portion 11 pivotally connected with the first assembly 10 and positioned at described second group Dead bolt portion 21 on part 20.

With reference to Fig. 2, a fore shaft 211 in the dead bolt portion 21, is formed.

Dead bolt holding part 112, the dead bolt holding part 112 is formed between the button portion 11 and the first assembly 10 For accommodating dead bolt portion 21.

The button portion 11 is connected with the first assembly 10 by rotating shaft 113, and one end of the button portion 11 is provided with lock Buckle 111, the button portion 11 are provided with press section 114 away from one end of latch part 111, and the rotating shaft 113 is located at the lock Between portion 111 and the press section 114.When the first assembly 10 and second component 20 are completed, the lock Portion 111 is limited in the fore shaft 211.

Specifically, with reference to Fig. 3, button portion 11 is a hat shape lid, and in arcuation, button portion 11 includes a button to its outline Portion's body（Do not indicate）And by button portion body towards two rotating shafts 113 protruded out on the outside of two, and the rotating shaft 113 and described the One component 10 is flexibly connected, the button portion 11 can by the relative first assembly 10 of rotating shaft 113 rotate clockwise or counterclockwise with Realize dismounting and assemble.

Here, locking direction, i.e. direction of the latch part 111 towards fore shaft 211 is defined as counterclockwise, is defined as solution clockwise Lock direction, i.e. direction of the latch part 111 away from fore shaft 211.

Certainly, the structure of rotating shaft 113 is not limited with described above, and in other embodiments, rotating shaft can run through for one presses The rod-like structure of key portion body.

In the dead bolt portion 21 inserts the dead bolt holding part 112 and the latch part 111 is not inserted into the fore shaft 211 When, the latch part 111, the press section 114 and the rotating shaft 113 essence is positioned at the same side in the dead bolt portion 21, such as Shown in Fig. 6, the latch part 111, the press section 114 and the rotating shaft 113 are respectively positioned on the top in the dead bolt portion 21.

In addition, the press section 114 is located at the side that the button portion 11 extracts direction X along second component 20, i.e., As shown in fig. 6, the press section 114 is located at the right side of the latch part 111.

It is appreciated that when the latch part 111 is inserted in the fore shaft 211, if now user outwards pulls second group Part 20, then dead bolt portion 21 can be by extracting the directed force F of direction X along the second component 20, and certainly, the second component 20 extracts direction The directed force F of X is not limited to the power that user outwards pulls generation.

As now rotating shaft 113 is located at the top in dead bolt portion 21, directed force F provide all the time button portion 11 1 order about it is described by Torque of the key portion 11 along rotate counterclockwise（Do not indicate）, and directed force F is bigger, the anticlockwise moment which produces is bigger.

And, as press section 114 is located at the side that the latch part 111 extracts direction X along second component 20, button Portion 11 can drive latch part 111 to be continued towards the rotation of 211 direction of fore shaft along rotate counterclockwise.

That is, in the presence of directed force F, button portion 11 is all the time with causing towards the trend for rotating counterclockwise First assembly 10 and the second component 20 realize self-locking, latch part 111 and fore shaft that the applying of directed force F can only allow in button portion 11 Cooperation between 211 is even closer, causes self-locking releasing without causing latch part 111 to depart from fore shaft 211.

In the present embodiment, the first assembly 10 has a through hole 101, and at least partly the button portion 11 passes through institute State through hole 101 and cooperate with the dead bolt portion 21.

That is, forming a through hole 101 on the housing of first assembly 10, and protruded out with 114 part of press section here As a example by housing.

The periphery of the through hole 101（That is housing parts）Including near the latch part 111 the first auxiliary section 102 and lean on Second auxiliary section 103 of the nearly press section 114, the press section 114 is limited at second auxiliary section 103.

The press section 114 has limiting section 1142, and the limiting section 1142 is abutted with second auxiliary section 103 With the spacing press section 114.

The limiting section 1142 is directed away from the convex portion that 11 direction of button portion protrudes out, convex portion limit for the end of press section 114 Make in the lower section of the second auxiliary section 103, thus, when button portion 11 is rotated clockwise or counterclockwise, press section 114 relative second Auxiliary section 103 is rotated without deviating from the second auxiliary section 103.

In the present embodiment, the locking device 100 also includes the first elastic component being connected with the press section 114 12, when first elastic component 12 compresses, first elastic component 12 forces in the press section 114 and causes the button Portion 11 retains towards the trend for rotating counterclockwise.

One end of first elastic component 12 supports the projection 1141 of first assembly 10, the other end and 114 lower section projection of press section It is mutually matched.

Here, when dead bolt portion 21 is inserted in dead bolt holding part 112, the end in the dead bolt portion 21 is substantially first to contradict to arrive Latch part 111, dead bolt portion 21 move on and so that button portion 11 turns clockwise, and the first elastic component 12 is squeezed and is pressed Contracting, then when the gradually convergence fore shaft 211 of latch part 111, the first elastic component 12 for being compressed drives button portion 11 to turn counterclockwise Move and latch part 111 is entered in fore shaft 211.

In a specific example, first elastic component 12 is uncompressed state in original state.

In another specific example, first elastic component 12 is compressive state in original state, thus, when described the One elastic component 12 drive button portion 11 to rotate counterclockwise and after latch part 111 is entered in fore shaft 211, first elastic component 12 still give button portion 11 1 orders about button portion 11 towards the power for rotating counterclockwise, so as to further avoid latch part 111 from taking off From fore shaft 211.

In the present embodiment, continue ginseng Fig. 5 and Fig. 6, the locking device 100 also includes being arranged at the first assembly The push and block part 13 for cooperating and the second elastic component 14 on 10, second elastic component 14 extract direction X along the second component 20 Extend.

When the dead bolt portion 21 is inserted in the dead bolt holding part 112, the dead bolt portion 21 is away from the second component 20 End extrudes the push and block part 13 and compresses second elastic component 14, and realizes as latch part 111 enters fore shaft 211 During self-locking, the second elastic component 14 remains compressive state.

Thus, when the first assembly 10 and second component 20 are in self-locking state, second elastic component 14 All the time thrust F1 that direction X is extracted in the dead bolt portion 21 1 towards the second component 20 is given by the push and block part 13.

Thrust F1 is identical with the effect of above-mentioned directed force F, and thrust F1 can further avoid latch part 111 from departing from lock Mouth 211.

In sum, after being completed second component 20 by extracting the power of direction X along the second component 20（Including Directed force F, thrust F1 etc.）When, the dead bolt portion 21 forces in the latch part 111 all the time and so that the latch part 111 is protected The trend for rotating is held towards locking direction.

Here, when the latch part 111 is limited in the fore shaft 211, first assembly 10 and second group are just realized The self-locking of part 20.

In addition, user only needs directly to insert the second component 20 be just capable of achieving in first assembly 10 both assemblings, while Just both dismountings are capable of achieving by depresses button portion 11, and the assembling/unloading process of first assembly 10 and the second component 20 is convenient Fast.

Importantly, when first assembly 10 and the second component 20 are completed, the dead bolt portion 21 forces in all the time The latch part 111 and cause the latch part 111 to retain towards the trend that the locking direction rotates, even if thus, second Component 20 is subject to external force effect also not disengage it from first assembly 10, and first assembly 10 is steady with the self-locking state of the second component 20 It is fixed reliable.

In the present embodiment, there is relative motion between fore shaft 211 and latch part 111, friction can be produced between the two, In order to improve the service life in dead bolt portion 21, dead bolt portion 21 is made up of high-abrasive material, preferably, dead bolt portion 21 is made up of iron plate.

In addition, for being detachably connected between the dead bolt portion 21 and second component 20, it is in a specific example, described Dead bolt portion 21 is bolted on the second component 20, can so improve the convenience of manufacture and assembling process, but not with this It is limited.

Further, in the present embodiment, after being completed（Under self-locking state）Second component 20 is subject to edge Second component 20 extracts the power of direction X（Directed force F of generation etc. is pullled including thrust F1 and user）When, the fore shaft 211 First contact site 2111 is interacted with the second contact site 1111 of the latch part 111, second contact site 1111 or institute The tangent plane and second component 20 for stating the second contact site 1111 is extracted and forms the first angle α between the X of direction, first angle α is acute angle or right angle.

Here, if the first angle α is too small, then equivalent to latch part 111 1111 convergence of the second contact site parallel to lock 21 upper surface of tongue, normal pressure F2 formed at latch part 111 by force analysis, thrust F1 and/or directed force F are too small, Cause the maximum static friction force between the first contact site 2111 and the second contact site 1111 too small, now, if first assembly 10 and When producing vibration in 20 course of work of the second component or applying less pressing force at the press section 114, latch part 111 will Depart from fore shaft 211 and unlocked condition occur, i.e., now the self-locking state of locker 100 is unstable.

If the first angle α is excessive, accordingly, the maximum between the first contact site 2111 and the second contact site 1111 can be caused Stiction is excessive, and user needs the larger pressing force of applying at press section 114 that latch part 111 could be caused to depart from fore shaft 211, thus, unblock inconvenience can be caused.

Therefore, the angle of the first angle α is unsuitable excessive, also unsuitable too small.

In the present embodiment, the range set of first angle α is 30 °≤α≤60 °, preferably, first folder Angle α=45 °.

In the present embodiment, first contact site 2111 is inclined-plane 2111, and the essence of the first contact site 2111 can be by locking The subregion of tongue 21 is bent to form.

The angle that the inclined-plane 2111 and second component 20 are extracted between the X of direction is the second angle（Do not indicate）, institute State the second angle equal with first angle α.

That is, first contact site 2111 is mutually matched with second contact site 1111.

In the present embodiment, second contact site 1111 is cambered surface 1111.

Here, second contact site 1111 is set to into cambered surface 1111, on the one hand, can be smooth in order to latch part 111 Into in fore shaft 211, on the other hand, the second contact site 1111 is always cambered surface with the first contact site 2111 and contacts so that lock The left and right side-play amount that portion 111 slips into whole dead bolt portion 21 during fore shaft 211 is less, improves the stability of 21 insertion of dead bolt portion.

Further, since the second contact site 1111 is the cambered surface protruded out towards 21 direction of insertion of dead bolt portion, when latch part 111 by When gradually slipping in fore shaft 211, dead bolt portion 21 is increasingly towards its direction of insertion and moves so that between first assembly 10 and second group 20 it Between gap be gradually reduced so that first assembly 10 is fitted close with the second component 20.
