Abstract
This Anti-rotating grommet that the utility model provides, comprise by pressure pad circle, also comprise two anti-rotation cards, become the straight angle between two anti-rotation cards and be positioned at by pressure pad circle periphery, with by pressure pad cast integrally, two anti-rotation cards can bend along respective base, and the spacing between two anti-rotation card bases is less than nut circumcircle, for preventing cap rotation.The utility model effectively can prevent cap rotation, link firmly can be connected and do not loosen, and efficiently solves prior art because of cap rotation and can not hold the firm problem connected.In addition the utility model manufacture is simple, cost is low, easy to use.
Description
Technical field
The utility model relates to fastening piece connection area.
Background technique
In the connection of power current, in order to assembling and disassembling is convenient, many employings fastening piece connects, with fastening piece connect maximum defect be connect nut or screw rod easily loosen, cause the surface of contact of joint reduce and cause connection position heating, cause burning out equipment breaking out of fire, at present, prevent the method for nut or screw bolt loosening from having several, such as use check nut, or install spring washer etc. additional.These conventional methods are used for some Placement effect of power current and bad, check nut or the spring washer nut when shaking larger equally can rotate to cause connecting and loosen, therefore how guaranteeing that the connection between nut and screw rod does not loosen, is that power current connects current problem demanding prompt solution.
Model utility content
The purpose of this utility model is to provide a kind of Anti-rotating grommet that can prevent cap rotation.
This Anti-rotating grommet that the utility model provides, comprise by pressure pad circle, also comprise and turn card, this anti-rotation card has two at least for matching use, become the straight angle and be positioned at by pressure pad circle periphery between two anti-rotation cards that pairing uses, and by pressure pad cast integrally, anti-rotation card can bend along respective base, spacing between the two anti-rotation card bases that pairing uses is less than nut circumcircle, for preventing cap rotation.
Simply be stuck in same manufacture plane by pressure pad circle and anti-rotation to manufacture, thickness is identical.
For the purpose of for subsequent use, a pair anti-rotation card damage can be right with another, and described anti-rotation card has multiple.
The utility model owing to being provided with anti-rotation card on the basis of existing packing ring, only anti-rotation card need be bent during use, two anti-rotation cards are made to be attached to two nuts or nut and screw rod spanner bit plane place respectively, nut just cannot rotate, link firmly can be connected do not loosen, efficiently solve existing link and connect unsteady problem.Especially can guarantee that check nut or screw rod do not relatively rotate in the application of power current connection, effectively can eliminate the potential safety hazard in electric current connection, there is the important meaning of producing with economically.In addition the utility model manufacture is simple, cost is low, easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is using state figure structure schematic representation of the present utility model.
Fig. 3 is the erection drawing of Fig. 2.
Embodiment
Fig. 1 reflects structure of the present utility model.As can be seen from Figure 1, the utility model still has and existing gasket function same section, is referred to as by pressure pad circle 1, two ears are being stretched out by pressure pad circle both sides, be called anti-rotation card 2, two anti-rotation card 2 with by pressure pad circle 1 at same plane, during use, anti-rotation card 2 needs bending.Crashproof card can have two to even more multipair, to use another right when a pair damage wherein.
Fig. 2 and Fig. 3 reflects using state of the present utility model, this is the embodiment that the utility model is used on a conducting connecting part, wherein A refers to Anti-rotating grommet, B is intermediate connector, C refers to check nut, this Anti-rotating grommet A is between intermediate connector B and check nut C, internal thread is had inside intermediate connector B, outer surface claims hexagonal prism structure as spanner position, a long nut can be considered as, after the relatively described intermediate connector of check nut C is tightened, one, the two anti-rotation card of Anti-rotating grommet A is bent to nut C, another spanner position to described intermediate connector B bends, anti-rotation card 2 is made to be attached to foreign side's plane of nut C and the spanner bit plane of described intermediate connector B respectively, because two anti-rotation card 2 spacing bent between base are less than the circumcircle of check nut six side, therefore check nut cannot rotate relative to anti-rotation card, anti-rotation card also cannot rotate relative to described intermediate connector B simultaneously, conducting connecting part is finally made firmly to connect.Serve the effect preventing check nut from loosening.Structure of the present utility model is simple, easy to manufacture, easy to use, prevents the effect of cap rotation very good, can be used for machinery and electrical connection.Be particularly suitable for the connection of conducting heavy current equipment or wire.
Claims (3)
1. an Anti-rotating grommet, comprise by pressure pad circle (1), characterized by further comprising and turn card (2), this anti-rotation card has two at least for matching use, become the straight angle and be positioned at by pressure pad circle periphery between two anti-rotation cards that pairing uses, and by pressure pad cast integrally, anti-rotation card can bend along respective base, spacing between the two anti-rotation card bases that pairing uses is less than nut circumcircle, for preventing cap rotation.
2. Anti-rotating grommet according to claim 1, it is characterized in that being stuck in same manufacture plane by pressure pad circle and anti-rotation, thickness is identical.
3. Anti-rotating grommet according to claim 1 and 2, is characterized in that described anti-rotation card has multiple, so that for subsequent use.
