Abstract
The utility model relates to a locking washer. The locking washer comprises a washer body. The locking washer is characterized in that the locking washer is in a conical casing shape; the upper end portion of the conical surface is provided with a cylindrical extension sleeve part; a plurality of fastener teeth are arranged at the bottom of the conical surface annularly; every fastener tooth is formed by two fastener pieces with folded angles. Accordingly, the locking washer has the advantages of being convenient to install, high in structural strength and good in fastening effect.
Description
Technical field
The utility model relates to a kind of lock washer, refers in particular to a kind of fastening lock washer of being convenient to.
Background technique
Packing ring is generally the part of pad between connected piece and nut.Be generally pancake metal ring, be used for protecting the surface of connected piece not abraded by nut, disperse the pressure of nut to connected piece.In order to adapt to different working environments, part packing ring has adopted the design of repousse and buckle pawl at fitting surface, prevents that fixed block from occurring loosening.But existing packing ring is owing to adopting sheet structure, installing and during dismounting, easily stuck with screw flight structure, be not easy to installation, have that fixed effect is bad, the shortcoming of the easy deformation failure of packing ring simultaneously.
Model utility content
For the deficiency existing in background technique, the utility model provides a kind of lock washer, have advantages of be convenient to install, structural strength is high, fastening effective.
For achieving the above object, the utility model provides following technological scheme: a kind of lock washer, comprises packing ring body; It is characterized in that: described packing ring is conical shell; The upper end portion of the conical surface arranges cylindrical extension external member, and the base circle of the conical surface arranges a plurality of snapper teeth, and snapper teeth consists of the buckling sheet of two knuckle settings.
The utility model is also further set to: described buckling sheet knuckle is between the two that infolding is in conical shell.
The utility model is also further set to: described knuckle is obtuse angle.
The utility model beneficial effect is compared to existing technology:
1. packing ring is conical shell, in use, packing ring is passed to fixing bolt; The upper end portion that cylindrical extension external member arranges conical shell when mounted with the head compression fit of bolt, make the overall construction intensity of packing ring larger, be difficult for producing distortion, simultaneously after installation, can produce certain pretightening force, arranging of cylindrical extension external member can effectively prevent that packing ring is stuck on the screw thread of construction bolt simultaneously, guarantees that packing ring can work;
2. the bottom that snapper teeth is arranged on conical shell coordinates with bolt stationary plane, the buckling sheet that two knuckles of snapper teeth arrange forms, even if distortion has appearred in snapper teeth, because two buckling sheets have adopted knuckle connection, the in the situation that of folding, also can reach the effect with junction surface buckle outside distortion.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is side view of the present utility model.
Number in the figure implication: the 1-conical surface; 2-snapper teeth; 21-buckling sheet; 3-extends external member.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
As depicted in figs. 1 and 2, a kind of lock washer, comprises packing ring body; Packing ring is conical shell; The upper end portion of the conical surface 1 arranges cylindrical extension external member 3, and extends external member 3 and coordinate with the termination of fixing bolt, and the base circle of the conical surface 1 arranges a plurality of snapper teeth 2, snapper teeth 2 and stationary plane secure fit, and snapper teeth 2 consists of the buckling sheet 21 of two knuckle settings.
Described buckling sheet 21 knuckle is between the two that infolding is in conical shell.
Described knuckle is preferably obtuse angle.
Working principle of the present utility model is: packing ring is conical shell, in use, packing ring is passed to fixing bolt; The upper end portion that cylindrical extension external member 3 arranges conical shell when mounted with the head compression fit of bolt, make the overall construction intensity of packing ring larger, be difficult for producing distortion, simultaneously after installation, can produce certain pretightening force, arranging of cylindrical extension external member 3 can effectively prevent that packing ring is stuck on the screw thread of construction bolt simultaneously, causes packing ring cisco unity malfunction; The bottom that snapper teeth 2 is arranged on conical shell coordinates with bolt stationary plane, the buckling sheet 21 that 2 two knuckles of snapper teeth arrange forms, even if distortion has appearred in snapper teeth 2, because two buckling sheets 21 have adopted knuckle connection, the in the situation that of distortion, also can reach the effect with junction surface buckle.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and modification, these of above-mentioned hypothesis improve and modification also should be considered as protection domain of the present utility model.
Claims (3)
1. a lock washer, comprises packing ring body; It is characterized in that: described packing ring is conical shell; The upper end portion of the conical surface arranges cylindrical extension external member, and the base circle of the conical surface arranges a plurality of snapper teeth, and snapper teeth consists of the buckling sheet of two knuckle settings.
2. a kind of lock washer according to claim 1, is characterized in that: described buckling sheet knuckle is between the two that infolding is in conical shell.
