Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below, by specific embodiment and referring to accompanying drawing, this utility model is elaborated.
In order to solve the problem that in prior art, wrist strap often can artificially be dismantled, this utility model embodiment provides a kind of wrist strap, as shown in Figure 1, comprising: wrist strap body 1, is connected to the first hand strap 2 and second hand strap 3 of described wrist strap body 1 both sides;
The end of described the first hand strap 2 is provided with card pin 4, and described the second hand strap 3 is provided with the hole clipping 7 that card pin 4 is inserted,
In described the first hand strap 2, be connected with engage with described hole clipping 7 at described card pin 4 after, again by buckle 5 fixing described card pin 4; And described buckle 5 is connected with described the first hand strap 2, and non-ly cannot dismantle under damage state based, that is, only have and destroy being under external force connected of buckle 5 and the first hand strap 2, just can make both depart from.
Visible, the wrist strap of this utility model embodiment is by after blocking pin 4 and engaging with hole clipping 7, then fixes card pin 4 by buckle 5, thereby prevents that card pin 4 and hole clipping 7 from throwing off.And, by being set, buckle 5 is connected with being connected to of the first hand strap 2 is non-dismountable, artificially buckle 5 is pulled down avoiding.
Wherein, spacing for card pin 4 is carried out, buckle 5 is provided with groove 53, and described groove 53 is corresponding one by one with described card pin 4.Preferably, in view of the limited space of the first hand strap 2 ends, referring to Fig. 3, it is two that the present embodiment arranges card pin 4, and fixing hole 6 is one, and fixing hole 6 is between two card pins 4.
In addition, buckle 5 has much with the non-dismountable mode being connected of the first hand strap 2, as riveted joint, bonding, welding etc., just the present embodiment will not enumerate.Below the syndeton of the buckle 5 in the present embodiment and the first hand strap 2 is described.
In the present embodiment, referring to Fig. 2 and Fig. 3, buckle 5 comprises buckle body 51 and is located at the fixed part 52 on described buckle body 51, and described the first hand strap 2 is provided with fixing hole 6; Fixed part 52 is mutually non-dismountable connection with fixing hole 6.
Wherein, fixed part 52 comprises and is multiplely the sub-fixed part 520 being circumferentially arranged, and the plurality of sub-fixed part 520 is along central shaft (not shown) symmetric arrays.A side away from described buckle body 51 of each described sub-fixed part 520 is provided with boss 54, and described boss 54 is towards deviating from the direction projection of described central shaft.
The gap of each described sub-fixed part 520 and described central shaft is greater than the bump sizes of described boss 54, to ensure that sub-fixed part 520 can have enough amounts of contraction when through fixing hole 6; And the outer peripheral face of described boss 54 and the ultimate range of described central shaft are greater than the radius of described fixing hole 6, to ensure that boss 54 can engage with the first hand strap 2 through after fixing hole 6.Wherein, the outer peripheral face of boss 54 refers to the side face that boss 54 deviates from a side of central shaft.
When connection, multiple described sub-fixed parts 520 are simultaneously through described fixing hole 6, each described boss 54 moves towards described central shaft under the effect of external force, and rely on after through described fixing hole 6 elastic return of described sub-fixed part 520 self to original position, to engage with described the first hand strap 2.
In the present embodiment, sub-fixed part 520 is for being greater than two.
And, can be through the rear automatic recovery of fixing hole 6 for what realize above-mentioned sub-fixed part 520, the material of sub-fixed part 520 can be chosen as has elastic plastics, metal etc., is preferably plastics, to save cost in the present embodiment.
Preferably, this boss 54 can be various structures, but in order to make it more easily through fixing hole 6, in the present embodiment, multiple described sub-fixed parts 520 surround and form the central through hole 55 with opening 56, and the outline of multiple described boss 54 forms the truncated conical shape with opening 56; Described round platform is along the direction convergent away from described buckle body 51 (being that the cross-sectional diameter of round platform is along reducing gradually away from the direction of buckle body 51), and the maximum gauge of the outline of described round platform is greater than the diameter of described fixing hole 6, the poor diameter that is less than or equal to described central through hole 55 of the diameter of described round platform and described fixing hole 6.
Wherein, the taper surface of round platform is more conducive to its stressed contraction.And, shrinking for the ease of round platform, the sub-fixed part 520 in the present embodiment is set to four, correspondingly forms four openings 56, and four openings 56 are axial array distribution along central shaft, to form the cross open of a centre as through hole on fixed part 52.This round platform 54, through after fixing hole 6, relies on the tension force of himself to restore to the original state, cannot be by it from the interior dismounting of fixing hole 6 by manpower, and become disposable locking device.
Preferably, fixed part 52 is after engaging, buckle body 51 fits with described the first hand strap 2, and the length that ensures the fixed part 52 between boss 54 and buckle body 51 equals the distance respectively and between boss 54 and buckle body 51 two end faces of fitting of the first hand strap 2.And for this partial fixing portion 52 is fitted better with fixing hole 6, the part between boss 54 and buckle body 51 that fixed part 52 is set is cylindrical structure.
Further, for round platform is more stably sticked on fixing hole 6, fixing hole 6 is set for shoulder hole, referring to Fig. 3.The aperture of the major part of shoulder hole 6 is greater than the maximum gauge of described round platform periphery, i.e. the diameter of the maximum cross section of round platform, thus round platform is sticked on shoulder hole 6.
If want to be taken off, need specific instrument that fixed part 52 is destroyed, buckle 5 could be taken off.For example, for the fixed part with four sub-fixed parts 520 52 in the present embodiment, only Phillips screwdriver need to be inserted to fixed part 52 and rotation turns, utilize this revolving force to destroy being connected of fixed part 52 and buckle body 51, then take off buckle body 51.
In order to be convenient to destroy in the time turning with screwdriver, the wall thickness of fixed part 52 and buckle body 51 junctions is set for being less than 2mm, the strength that rotation turns is like this easy to be twisted into two parts.Based on this, the central through hole diameter d 1 that fixed part 52 is set is 1.8-2.2mm, is 2mm in the present embodiment, and connecting boss 54 is 5mm with fixed part 52 outside diameter d 4 of buckle body 51, like this, the wall thickness of the fixed part 52 between boss 54 and buckle body 51 is 1.5mm.
In addition, for ensureing that round platform can be smoothly through fixing hole 6 when, can not deviate from from fixing hole 6 easily, in the present embodiment, the diameter d 2 of fixing hole 6 is 4.9-5.1mm, is 5mm in the present embodiment, the maximum cross section diameter d 3 of round platform is 6.5-6.7mm, and the present embodiment is 6.6mm.
Certainly, the above-mentioned size numerical value of enumerating is only a concrete example, when actual use, can adjust voluntarily as required, and the present embodiment is just no longer enumerated.
From above-mentioned, the wrist strap of this utility model embodiment is buckled in use, first by hole clipping 7 clampings in the card pin 4 in the first hand strap 2 and the second hand strap 3, again buckle 5 is connected with the first hand strap 2, to fix card pin 4, thereby wearer can only could be taken off with being connected of the first hand strap 2 by destroying buckle 5, thereby prevented random artificial dismounting.And this wrist strap is simple in structure, with low cost, fitting operation is very convenient.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any amendment of making, be equal to replacement, improvement etc., within all should being included in the scope of this utility model protection.
