Description
Technical field
The utility model belongs to the machanical fastener technical field, especially has the fastening piece of antitheft merit, locking energy.
Background technique
Fastening piece is to be fastenedly connected to use and use class mechanical parts very widely.On various machineries, equipment, vehicle, boats and ships, railway, bridge, building, structure, instrument, instrument, instrument and articles for use etc., can see fastening piece miscellaneous.For preventing that by the dismounting of non-original idea increasing people carries out the research of some anti-theft fastening pieces.It is the anti-theft nut of ZL01231049.2 that the design people discloses the patent No. at Chinese utility model patent, this model utility is made up of nut body and the shell that covers on the body, nut body has the circle groove, shell inner face and its opposite position also have the circle groove, one slotted collar 3 is arranged in the nut body groove, this nut body top is hexagonal section, the bottom is a circular cross-section, groove is positioned at the bottom, the following partial cross section of shell inner face groove is curved, body of clasp has part to protrude in nut body, and shell is cylindrical, and its upper-end surface is a ring.The anti-theft nut of this structure has advantages such as parts are few, simple in structure, the assembling cooperation is easy.But, must be suitable with the nut and the shell on the body of band slotted collar, can not use the conventional criteria nut, versatility is not strong; In addition, do not have locking functions,, have certain defective especially in occasions such as electric power facility, rail facilities.
The model utility content
The purpose of this utility model is to provide a kind of highly versatile, and has locking functions, the antitheft fastener that parts are few, simple in structure.
For achieving the above object, the utility model has adopted following technological scheme to be: the antitheft fastener of a kind of combined multifunctional, comprise nut, packing ring and shell, the shell inner face has the circle groove, it is characterized in that: jacket is on nuts and washers, the outer ring of the corresponding packing ring of groove that is provided with the shell inner face is provided with gasket recess, and a slotted collar is arranged in the gasket recess of packing ring outer ring.
During concrete enforcement, the following partial cross section of shell inner face groove is curved.
During concrete enforcement, shell is cylindrical, and its upper-end surface is a ring.
During concrete enforcement, nut is a lock nut.The lock nut type is a lot, contains locking spring sheet or nylon as head and is used for locking lock nut and uses more extensive.
During use, gasket sleeve on bolt, precession nut simultaneously, be fastened on the packing ring, under the jacket, strike downwards again with instrument, snap ring on shell and gasket recess is collided, because the following partial cross section of shell inner face groove is curved, slotted collar can be compressed into gasket recess gradually, and shell is continued down, relative up to gasket recess with the groove of shell, snap ring ejects because of elastic reaction, and the part body of clasp enters the groove of shell, and then shell is blocked.Like this, nut is covered, and can't touch nut, and the turn shell, shell is circular, only can rotate round packing ring, can not drive nut to rotate, thus can't unscrew nut, thus play antitheft effect.Owing to original technology is improved, can be used different nuts, highly versatile at different occasions; Owing to increased packing ring, nuts and washers is close to, and plays certain locking effect; In addition, nut adopts lock nut, improves locking functions widely.
The beneficial effects of the utility model are: the utility model is simple in structure, can use the combination of different nuts at different occasions, and is practical, antitheft, anti-loosing effect is good.
Description of drawings
Below in conjunction with drawings and Examples model utility is further specified.
Fig. 1 is the utility model embodiment's a structural representation.
Fig. 2 is the utility model embodiment's a cut-away view of outer cover.
Fig. 3 is the utility model embodiment's a packing ring schematic representation.
Among the figure: 1, nut 2, shell 3, packing ring 4, slotted collar 21, groove 31, gasket recess
Embodiment
Among Fig. 1, the antitheft fastener of a kind of combined multifunctional of this model utility is made up of nut 1, shell 2, packing ring 3 and slotted collar 4, and nut 1 adopts lock nut.In conjunction with as shown in Figure 2, shell 2 is rounded, and inner face is provided with groove 21, and the upper-end surface of shell 2 is ring, and Circularhole diameter is identical with the screwhole diameter of nut 1.In conjunction with as shown in Figure 3, groove 21 corresponding packing rings 3 outer rings that are provided with shell 2 inner faces are provided with gasket recess 31, and a slotted collar 4 is arranged in the gasket recess 31 of packing ring 2 outer rings.As shown in Figure 1, shell 2 covers on nut 1 and the packing ring 3, and slotted collar 4 is stuck between the groove 21 of gasket recess 31 and shell 2.During use, packing ring 3 is enclosed within on the bolt, the nut of precession simultaneously 1, be fastened on the packing ring 3, again down shell 2 covers, strike downwards with instrument, when shell 2 and the slotted collar 4 on the gasket recess 31 are collided, because shell 2 inner face grooves 21 following partial cross sections are curved, slotted collar 4 can be compressed into gasket recess 31 gradually, and shell 2 is continued down, relative up to gasket recess 31 with the groove 21 of shell 2, slotted collar 4 ejects because of elastic reaction, and part slotted collar 4 enters the groove 21 of shell 2, and then shell 2 is blocked.Like this, nut 1 is covered, and the outside can't touch nut 1, and turn shell 2, shell 2 is circular, only can rotate round packing ring 3, can not drive nut 1 to rotate, thus can't unscrew nut 1, thus play antitheft effect.Owing to increased packing ring 3, nut 1 and packing ring 3 are close to, and play locking effect; In addition, nut 1 adopts lock nut, improves locking functions widely.
