Abstract
The utility model relates to a kind of quick mounting screw with rotatable key, comprises screw rod, and described screw rod is divided into the thread section on top and the polished rod section of bottom, described polished rod section offers keyway, is equiped with rotating rotation key in keyway.Owing to implementing technique scheme, the application is arranged by rotation key and bending part two place, screw rod can be made to be fixed on fast in screw, difficult drop-off, thus working tool can firmly be used.The application installs fast, indirectly reduces the activity duration.
Description
Technical field
The utility model relates to a kind of quick mounting screw with rotatable key.
Background technique
Change in the work of insulator in high voltage transmission line live work equipotential, usually need the working tool using a kind of " machete card " by name, this instrument needs to twist with one piece of hand to be bolted in the gold utensil hole of circuit in use, hand twists bolt being screwed into after in gold utensil hole, not easily fastening, and easily come off by vibration in operation process, relevant operating apparatus cannot firmly be used, therefore need repeatedly to check whether put in place when installing hand and twisting bolt, also need at work repeatedly to check whether hand tighten screw gets loose, thus increase operating time.
Summary of the invention
The purpose of this utility model is to propose one can quick mounting, the not caducous quick mounting screw with rotatable key.
The purpose of this utility model is achieved in that the quick mounting screw with rotatable key, comprise screw rod, described screw rod is divided into the thread section on top and the polished rod section of bottom, described polished rod section offers keyway, is equiped with rotating rotation key in keyway.
Owing to implementing technique scheme, the application is arranged by rotation key and bending part two place, screw rod can be made to be fixed on fast in screw, difficult drop-off, thus working tool can firmly be used.The application installs fast, indirectly reduces the activity duration.
Accompanying drawing illustrates: concrete structure of the present utility model is provided by following drawings and Examples:
Fig. 1 is the quick mounting screw structural schematic diagram with rotatable key.
Legend: 1, screw rod; 2, thread section; 3, keyway; 4, polished rod section; 5, key axle; 6, hole clipping; 7, bending part; 8, rotation key.
Embodiment:
The utility model by the restriction of following embodiment, can not determine concrete mode of execution according to the technical solution of the utility model and actual conditions.
Embodiment: as shown in Figure 1, quick mounting screw with rotatable key comprises screw rod 1, and described screw rod 1 is divided into the thread section 2 on top and the polished rod section 4 of bottom, and described polished rod section 4 offers keyway 3, in keyway 3, be equiped with rotating rotation key 8, described keyway 3 rear portion is bending part 7.
The polished rod section 4 at described keyway 3 place offers axis hole, and be installed with key axle 5 in axis hole, rotation key 8 is installed on key axle 5.Described key axle 5 two ends exposure polished rod section 4, two ends becomes and forms dop greatly.
Described bending part 7 offers the hole clipping 6 corresponding with aforementioned dop.
Described keyway 3 is groove, and rotation key 8 is rectangle, and its bond length is less than keyway 3 degree of depth, and long edge lengths is greater than keyway 3 degree of depth.
During use, first rotation key 8 is rotated, make rotation key 8 be hidden in keyway 3 completely, again the application is passed gold utensil screw, thread section 2 and gold utensil screw are spun, and now polished rod section 4 is passed by gold utensil screw, rotate rotation key 8, make its long limit exposure in keyway 3.Subsequently, bent laterally by bending part 7, until bending part 7 is stacked with polished rod section 4, key axle 5 outer end dop snaps in hole clipping 6 on bending part 7, bending part 7 and polished rod section 4 is located.Now because keyway 3 is stretched out at rotation key about 8 two ends, therefore screw rod 1 cannot be deviate from by gold utensil screw.Simultaneously due to the bending of bending part 7, itself and the stacked thickness of polished rod section 4 are also greater than gold utensil screwhole diameter, and screw rod 1 cannot be deviate from by gold utensil screw equally.
Above technical characteristics constitutes most preferred embodiment of the present utility model, and it has stronger adaptability and best implementation result, can increase and decrease inessential technical characteristics according to actual needs, meet the needs of different situations.
