Abstract
The utility model provides a bolt anti-loosening clamp easy to install, and relates to the technical field of machines. A piece of spring steel is bent into a U-shaped steel sheet, the two ends of the U-shaped steel sheet are respectively provided with a set of dodecagonal petal blocking piece, the dodecagonal petal blocking pieces can be easily installed at the head of a power transmission and transformation conductor connecting clamp bolt and the six side walls of a nut to prevent relative rotation of a threaded rod and the nut, therefore, the bolt is prevented from loosening, the accident that due to the fact that power transmission equipment generates heat, lines are broken or the power transmission equipment is forced to be shut down is avoided, and meanwhile the detection and maintenance cost is lowered.
Description
Technical field
The utility model relates to field of mechanical technique, is specifically related to a kind of anti-loosening device of bolt.
Background technique
Bolt is for being fastenedly connected two parts with through hole.In existing bolt connecting mode, usually adopt screw retention packing ring to prevent bolt looseness.In the time that the vibration equipment at bolt place is frequent, be difficult to avoid part bolt to occur loosening, even come off, thereby cause even field accident of equipment failure.In electric power system power transmission and transforming equipment, the connection of the conductor of transferring high voltage electric current is usually used bolt and is connected, and in the time there is bolt looseness, can cause the gold utensil bad connections such as connecting clamp to cause heating defect, and broken string accident even occurs.The power transmission and transforming equipment causing due to bolt looseness is forced to stop power supply or accident is stopped power supply, and its loss often reaches hundreds thousand of even millions of units.Under electriferous state, lack direct approach and detect bolt looseness, generally take thermal infrared imager indirect detection temperature variation to judge whether to need maintenance, O&M cost is higher.
Utility model patent " a kind of screw retention card " (application number: 2013206026260), preferably resolved the problems referred to above being proposed by the applicant.But also deposit nut and bolt head when mounted and need to rotate to appropriate angle, be just beneficial to locking cutting ferrule and enter nut and bolt head, serve inconvenience to mounting strap.
Summary of the invention
The utility model object is to provide a kind of easily dress screw retention card, and while installation to solve above-mentioned a kind of screw retention card, nut and bolt head need to rotate to appropriate angle and be just beneficial to the problem of installation.
To achieve these goals, the utility model provides a kind of easy dress screw retention card, comprises that a U-shaped steel disc two ends trepanning entangles respectively head and the nut of bolt, and the trepanning that it is characterized in that two ends is 12 jiaos of holes of impact briquetting band petal catch.Above-mentioned petal catch, the petal catch of head one end is towards U-shaped outside, and the petal catch of nut one end is towards U-shaped inner side.The wherein dual-side petal catch length of the petal catch of above-mentioned nut one end is 6～8 millimeters, and all the other petal catch length are 2～5 millimeters.U-shaped steel disc is made up of spring steel, and U-shaped opening opens and packs into after bolt, can elastic clamping bolt and loosening.
Easy dress screw retention card of the present utility model, when mounted, the dodecagon petal catch at two ends is packed into respectively to the head of nuts and bolt, the sidewall butt of the head of petal catch and nuts and bolt, prevent the relative rotation of nuts and bolt, and then reach and prevent the object being become flexible and come off by chek bolt, avoid the equipment failure and the field accident that cause because of bolt looseness, realize the locking non-maintaining of bolt fastener.
Brief description of the drawings
Fig. 1 is easy dress screw retention card structure schematic diagram of the present utility model;
Fig. 2 is that easy dress screw retention of the present utility model is stuck in the structural representation under use state.
Embodiment
Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
As shown in Figure 1, the easy dress screw retention card of the present embodiment, comprises petal catch 1, petal catch 2, U-shaped steel disc 3.Petal catch 2 wherein dual-side petal catch length is 6～8 millimeters, and all the other petal catch length are 2～5 millimeters.
As shown in Figure 2, in use, petal catch 1 packs into the sidewall of nut 6 to the present embodiment, and petal catch 2 packs into the sidewall of the head 5 of bolt.Because the trepanning at two ends is 12 jiaos of holes of impact briquetting band petal catch, add the deformation behavior that easily fills locking card, can meet the head 5 and the nut 6 that easily fill locking card and easily pack into bolt, even if they are in various orientation.U-shaped steel disc 3 is made up of spring steel, U-shaped opening opens and packs into after bolt, can elastic clamping bolt and loosening, by U-shaped steel disc 3, bolt 4 is connected into as a whole, stop the relative rotation of nuts and bolt, prevent bolt looseness, avoid transmission facility heating to cause broken string or forced outage accident, reduce and detect and maintenance cost simultaneously.
Claims (4)
1. a screw retention card, comprises that a U-shaped steel disc two ends trepanning entangles respectively head and the nut of bolt, and the trepanning that it is characterized in that two ends is 12 jiaos of holes of impact briquetting band petal catch.
2. screw retention card according to claim 1, is characterized in that described petal catch, and the petal catch of head one end is towards U-shaped outside, and the petal catch of nut one end is towards U-shaped inner side.
3. screw retention card according to claim 1, is characterized in that the wherein dual-side petal catch length of the petal catch of described nut one end is 6～8 millimeters, and all the other petal catch length are 2～5 millimeters.
4. screw retention card according to claim 1, is characterized in that described U-shaped steel disc is made up of spring steel, and U-shaped opening opens and packs into after bolt, can elastic clamping bolt and loosening.
