Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
Embodiment Anti-removing wrist strap snap close as shown in Figures 1 to 4, snap close body 2, the vacuum cover 3 being provided with negative pressure air-out hole 31, back-moving spring 4, lock pin 5 and the rubber diaphragm 6 coordinated with wrist strap 1 including wrist strap 1.Wrist strap 1 is provided with wrist strap groove 11, and wrist strap afterbody 12 connects the bottom of snap close body 2, and wrist strap head 13 is through the middle part of snap close body 2.Snap close body 2 and vacuum cover 3 form vacuum storehouse 7, and back-moving spring 4, lock pin 5 and rubber diaphragm 6 are located in vacuum storehouse 7, and rubber diaphragm 6 is located at the bottom surface in vacuum storehouse, and the upper end of back-moving spring 4 connects vacuum cover 3, and the lower end of back-moving spring 4 connects lock pin 5.Lock pin 5 passes rubber diaphragm 6 and snap close body 2 and inserts wrist strap groove 11, it is achieved locking wrist strap 1.
The present embodiment uses vacuum storehouse 7, negative pressure air-out hole 31, back-moving spring 4, rubber diaphragm 6 and lock pin 5 structure, utilize the feature that lock pin 5 stroke is shorter, and utilize draught head principle, the elastic deformation characteristic of rubber diaphragm 6, compression reseting spring 4 band pendulum lock pin 5 move, reach the purpose unlocking and locking, unlock the unlocker device needing to use vacuum cup and simple vacuum pump to constitute, reach anti-and privately disassemble lock construction and purpose；Modern design, simple in construction, intensity are high, it is particularly suitable for the situation needing to prevent carrier realizing self disassembling for administrative purposes, as the crowds such as special population, amentia old man, child carry, it is also very suitable for the outdoor activity of general population under room temperature, paddles and carry when moving.
The T-shaped structure in cross section of lock pin 5, the top of lock pin 5 is provided with lockpin hole 51, and the lower end of back-moving spring 4 is inserted in lockpin hole 51.The bottom of lock pin 5 is the Locked segment 52 for inserting wrist strap groove 11, and Locked segment 52 is tenon structure in inclined-plane side.Lock pin 5 uses nonmagnetic alloy microdiecast or engineering plastics ABS injection mo(u)lding.Wrist strap groove 11 is square hole structure, and during locking, Locked segment 52 inserts in wrist strap groove 11, prevents wrist strap head 13 from rotating, it is ensured that the Locked segment 52 of lock pin 5 is perpendicular to wrist strap head 13 all the time, it is simple to the present embodiment locking and unlatching.
Vacuum cover 3 is the overall structure of an evagination, the cross section of vacuum cover 3 is similar to inverted V-shaped structure, top 34 including the insertion section 32 in toroidal, connecting portion 33 and planar shape, insertion section 32 connects top 34 by connecting portion 33, top 34 is located in negative pressure air-out hole 31, the inwall at the connection top, upper end 34 of back-moving spring 4.The end face 21 of snap close body is provided with mounting groove 22, insertion section 32 and mounting groove 22 and coordinates for air-tightness tight dimensional, forms vacuum storehouse 7.In the present embodiment, vacuum cover 3 uses 304 stainless steel material punch formings or engineering plastics ABS injection mo(u)lding, antirust, coercive force absorption, the outer surface of connecting portion 33 and the smooth outer surface at top 34, opening band for vacuum, vacuum cover 3 can be locked with the V-arrangement sucker of unlocking apparatus and air tight.In the present embodiment, owing to locking and the opening travel of bracelet claps are all 3mm, the height in vacuum storehouse 7 is greater than 3mm.
In the present embodiment, snap close body 2 uses alloy precision die cast or engineering plastics ABS injection mo(u)lding, resistance to difference variation, and structural strength is high, and snap close body 2 is affixed with wrist strap afterbody 12, non-dismountable.
Rubber diaphragm 6 uses nitrile rubber to make, and is close to the bottom surface in vacuum storehouse 7, and the outer edge surface of rubber diaphragm and the inwall of vacuum cover 3 closely cooperate.Rubber diaphragm 6 is provided with lockpin hole 61, and lock pin 5 is through lockpin hole 61.Owing to locking and the opening travel of lock pin 5 are all 3mm, therefore rubber diaphragm 6 has elastic Light deformation function, and the axial resilience force of rubber diaphragm 6 and the elastic force of back-moving spring 4 ensure that the reset lockout power of lock pin 5, prevent the present embodiment lock in person even if.
A length of about the 200mm of wrist strap 1, thickness is about 2.5mm.The width of snap close body 2 is 25mm, a length of 30mm, and height is about 17mm.The middle part of snap close body 2 is provided with wrist strap and buckles groove 23, when wearing, wrist strap head 13 is inserted through wrist strap and buckles groove 23, when feeling that elasticity is moderate, can stop, the present embodiment self-locking.
Further illustrate as to the present embodiment, its operation principle is now described: when Lock-Picking Devices siphon away the gas in vacuum storehouse 7 by being located at the negative pressure air-out hole 31 of vacuum cover 3, reason due to draught head, gas outside vacuum storehouse 7 can act at the lockpin hole 61 of rubber diaphragm 6, compressing rubber diaphragm 6 deformation compression reseting spring 4, thus band pendulum lock pin 5 axially (i.e. Z-direction) moves in vacuum storehouse 7, lock pin 5 departs from wrist strap groove 11, realizing releasing the locking state of wrist strap 1, wrist strap 1 can freely be untied and realize the present embodiment and unblank.Whole releasing process is secondary and D.C. magnetic field without compound movement, the components and parts such as intelligent chip, sensitive circuit components and parts, electromagnetic induction unit in human body and the watch body being located at wrist strap 1 will not be produced damage.User can be worn voluntarily, carries out locking according to self size in wrist week, when without special unlocker device, it is impossible to unlock voluntarily, has reached Anti-dismantling purpose.
Other structure of the present embodiment sees prior art.
The invention is not limited in above-mentioned embodiment, if various changes or modification to the present invention are without departing from the spirit and scope of the present invention, if within the scope of these change claim and the equivalent technologies belonging to the present invention with modification, then the present invention is also intended to comprise these change and modification.
