As shown in Figures 2 and 3, latch components 30 include lock tongue 31, lock body 32 and locking bolt 33.As shown in Figure 4 and Figure 5, it locks
The latch hook 312 that tongue 31 main body 311 and be set in the first main body 311 including first, the first main body 311 is used for and cover board 20 connects
It connects；The first slot 322 is provided on lock body 32；Locking bolt 33 includes the second main body 331 and is set to sealed in the second main body 331
Portion 332, locking part 332 can be plugged in the first slot 322, fracture 333 are provided on locking part 332, and fracture 333 refers to
Thickness and/or material at this etc. make this be in the lower easy fracture of certain external pull effect.Latch components 30 have sealed
State and unlocked state, wherein locked state refer to that locking part 332 is plugged in 31 hook of lock tongue after the first slot 322 of lock body 32
State on 33 locking part 332 of locking bolt；Unlocked state refers to that external force extracts locking bolt 33 so that fracture 333 outward
The state that fracture and then locking bolt 33 are detached from lock tongue 31 and lock body 32；Wherein, latch components are made by the fracture of fracture 333
30 are converted to unlocked state from locked state.
Antitheft disposable lock buckle assembly 30 is arranged on packing case, increases the peace of packing case for present embodiment
Quan Xing；And need destruction locking bolt 33 that can just open the box, whether can completely prompt user's lock by locking bolt 33
Whether component 30 is opened；And lock tongue 31 and lock body 32 do not damage in releasing process, which can be recycled, more
It is economic and environment-friendly；In addition, the latch components 30 that present embodiment provides are simple in structure, the locking effect of latch hook 312 is more preferable.
Connection type between first main body 311 and cover board 20 is unlimited, as a kind of specific embodiment, as shown in figure 4,
First main body 311 includes the first plate body 3111 of two pieces of interconnections, and one of first plate body 3111 is set to cover board 20
Outside, another piece of the first plate body 3111 are set to the inside of cover board 20, can pass through clamping, spiral shell between two piece of first plate body 3111
The modes such as nail connection connect.Wherein lock tongue 31 is preferably to be connect with the first plate body 3111 positioned at 20 outside of cover board.
The connection type that connection type between lock body 32 and babinet 10 is referred between the first main body 311 and cover board 20 is set
It sets, i.e., lock body 32 includes two interconnections and spaced jam plate 321, one of jam plate 321 are set in babinet 10
Side, another jam plate 321 are set to 10 outside of babinet, can be connected by modes such as clamping, screw connections between two jam plates 321
It connects, the corresponding position of two jam plates 321 is respectively arranged with the first slot 322, and the second slot is formed between two pieces of jam plates 321
323, the second slot 323 is used to be inserted into for lock tongue 31, and the second slot 323 is connected to the first slot 322.
It should be noted that in other embodiment, the first main body 311 can also be enabled to be connect with babinet 10, lock body 32 with lid
Plate 20 connects.
The structure of locking part 332 is unlimited, can be hooked together with latch hook 312.But it is sealed in order to avoid latch hook 312 is detached from
Portion 332 includes interconnecting piece 3321 and two sides 3322, and two sides 3322 connect with interconnecting piece 3321 and the second main body 331 respectively
It connects.That is, locking part 332 and the second main body 331 form loop configuration.In order to facilitate processing, smooth fracture, interconnecting piece can be enabled
3321 and the junctions of two sides 3322 be fracture 333.
In order to enable the buckle structure locking effect is more preferable, the quantity of latch hook 312 is two, the hook portion of two latch hooks 312
Back to setting, two latch hooks 312 are respectively used to hook together with two sides 3322.
Since latch components 30 are made of plastic material, latch hook 312 have certain elasticity, can with deformation so that be caught in
And hook is set on locking part 332, in order to further increase the deformation range of latch hook 312, and then facilitates the insertion of lock tongue 31, it can be with
Make the first gap 314 for having for 312 deformation of latch hook between two latch hooks 312.And in order to avoid the excessive deformation of latch hook 312 is led
Latch hook 312 is caused to damage, as shown in figure 4, setting is located at the block 313 between two latch hooks 312, block in the first main body 311
313 form the first gap 314 between two latch hooks 312 respectively.Block 313 can limit the deformation range of latch hook 312 so that
It can conveniently be caught in and be unlikely to damage.
Please continue to refer to Fig. 4, in order to protect latch hook 312, latch hook 312 is avoided to be damaged during recycling, first
In main body 311 occlusion part 315, occlusion part 315 and latch hook 312 adjacent thereto are respectively arranged in the outside of two latch hooks 312
Between there is the second gap 316 for accommodating locking part 332.The shape of occlusion part 315 is unlimited, can block latch hook 312 i.e.
Can, the end of occlusion part 315 is preferred but is not limited to flush or stretch out in the end of latch hook 312 with the end of latch hook 312.
The application method of the packing case and latch components 30 of present embodiment offer is provided briefly below：
Pass through the process of 30 sealed packing case of latch components：
Locking bolt 33 is inserted into the first slot 322 of lock body 32, specifically, the locking part 332 of locking bolt 33 distinguishes grafting
Into the first slot 322 of two pieces of jam plates 321；Cover board 20 is rotated down so that the latch hook 312 of lock tongue 31 is inserted into two pieces of locks
In the second slot 323 formed between plate 321；It is rotated further cover board 20, two latch hooks 312 are inserted into the locking part of locking bolt 33
332 inside, at the same time, the deformation slightly of two latch hooks 312 are simultaneously close to each other；Cover board 20 is closed completely, and 312 hook of latch hook is set to
On two sides 3322 of locking part 332, latch components 30 and packing case are in locked state.
The releasing process of latch components 30 and packing case：
Locking bolt 33 is pulled out, at this point, two fractures 333 of the locking part 332 of locking bolt 33 break under external force
It splits, extracts locking bolt 33, latch components 30 are in the unlocked state, open cover board 20.
The technical principle of the present invention is described above in association with specific embodiment.These descriptions are intended merely to explain the present invention's
Principle, and it cannot be construed to limiting the scope of the invention in any way.Based on the explanation herein, the technology of this field
Personnel would not require any inventive effort the other specific implementation modes that can associate the present invention, these modes are fallen within
Within protection scope of the present invention.
