Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.
As shown in fig. 1 to 3, the utility model discloses an anti-drop round pin fastener for electric power construction, including bolt 1, nut 2 and pin rod 3. The bolt 1 passes through a mounting hole reserved on the mounting frame, the nut 2 is connected to the bolt 1 in a threaded mode to fix and assemble the mounting frame, a pin hole 9 perpendicular to the screw rod is formed in the outer side, located on the nut 2, of the bolt 1, and the pin rod 3 is inserted into the pin hole 9 in an inserting mode.
The right side of the pin rod 3 is fixedly provided with a limiting seat 10, and the limiting seat 10 is in limiting fit with the bolt 1. The left side fixed mounting of pin pole 3 has round pin head 7, is provided with recess 14 on the round pin head 7, and fixed mounting has pivot 6 in the recess 14, and the damping is linked stopper rod 5 on the pivot 6.
The pin rod 3 is sleeved with a limiting sleeve 4 between a pin head and a bolt, and the diameter of the limiting sleeve 4 is larger than that of the pin hole 9. The pin rod 3 is provided with mounting grooves 17 corresponding to the limiting sleeve 4 along the circumferential direction, and the mounting grooves 17 extend along the radial direction. In this embodiment, there are two mounting grooves 17, and a central angle between the two mounting grooves 17 is 180 °.
All sliding connection has slide 13 in two mounting grooves 17, two slides 13 are close to the equal fixed mounting in one side each other and have locking spring 18, two locking spring 18 are close to the equal fixed mounting in one side each other on mounting groove 17 bottom inner wall, two slides 13 keep away from the equal fixed mounting in one side each other and have locking lever 15, correspond two locking lever 15 departments on the stop sleeve 4 and all be provided with lockhole 16, during the fastening, two locking levers 15 keep away from one side each other and all extend outside lockhole 16.
Limiting sleeve 4 right side is provided with leather sheath 8, and leather sheath 8 cup joints on pin pole 3, increases the laminating degree between pin pole 3 and pinhole 9 through leather sheath 8, prevents that rainy day rainwater infiltration pinhole 9 is interior to become rusty and influences bolt 1's life.
Spacing seat 10 right side fixed mounting has pull ring 11, is convenient for plug pin rod 3 through pull ring 11, is favorable to using.
The bolt 1 is sleeved with the gasket 12, the contact area is increased through the gasket 12, the pressure is reduced, looseness is prevented, and parts are protected.
The diameter of stop sleeve 4 is greater than the diameter of pinhole 9, and the diameter through stop sleeve 4 is greater than the diameter of pinhole 9 and makes stop sleeve 4 can further fix spacingly to pin pole 3, prevents that pin pole 3 from taking off.
The pin head 7, the pin rod 3, the limiting sleeve 4, the pull ring 11 and the limiting seat 10 are made of stainless steel, the service life of the fastening device is further prolonged by utilizing the characteristic that the stainless steel is not easy to corrode, and meanwhile, the pin rod 3 and the bolt 1 are prevented from being corroded and are difficult to disassemble.
Specifically, the utility model discloses during the use, through in passing the mounting hole of reserving on the mounting bracket with bolt 1, fix the equipment to the mounting bracket on bolt 1 with 2 threaded connection of nut, press two locking levers 15 on pin 3 to the mounting groove 17 in, pass pin 3 pinhole 9 again, then cup joint pin 3 with stop sleeve 4 on, cup joint in-process and rotate stop sleeve 4, when lockhole 16 aims at locking lever 15, two 18 return of locking spring drive two slides 13 and slide towards keeping away from one side each other, make two locking levers 15 extend respectively outside lockhole 16, fix spacingly to stop sleeve 4, rotate stop lever 5 and pivot 6 at last, make be ninety degrees between stop lever 5 and round pin head 7, stop lever 5 offsets with stop sleeve 4, accomplish the installation.
The utility model discloses an anti-drop round pin fastener has solved traditional spacer pin simple structure, and spacing fixed mode is single, appears the pine easily after long-term the use and takes off, and the lower problem of fastening nature is generally used for main atress component department.
The anti-drop round pin fastener of this embodiment fixes spacingly through gag lever post 5, spacing sleeve 4 to pin rod 3, and pin rod 3 carries out spacing fixed to nut 2, utilizes the multiple spacing fastening mode that the ring was detained mutually to have improved anti-drop round pin fastener's fastening nature greatly, and the installation is dismantled conveniently between pin rod 3 and the bolt 1 simultaneously, has high practicality, is worth promoting.
