Technical field
The invention belongs to mechanical manufacturing field, relate to a kind of mechanical locking device, especially relate to a kind of high-temperature sealing anchor locking-nuts with twolug.
Background technique
Nut check is mechanical connection manner commonly used in the prior art, be widely used in various machinery industries, it is commonly used to self-locking nut in the structure of the industries such as Aeronautics and Astronautics, boats and ships, high ferro connects, common self-locking nut is to produce coupling mechanism force by the screw thread mode of texturing, adopt this locking mode need to carry out test of many times and could keep coupling mechanism force, and high and low temperature resistance is relatively poor.But at some box containers required sealed type self-locking nut in connection and the fastening installation is installed, the fastening piece that needs a kind of high-low temperature resistant sealing to have auto-lock function in installation process connects, and requiring has good anti-vibration, locking, decay resistance, is convenient to quick mounting, dismounting.Can not satisfy the usage requirement that this type of box container connects for existing common self-locking nut, therefore how develop a kind of high-low temperature resistant, good seal performance, and the self-locking nut of installation, convenient disassembly belong to current problem demanding prompt solution in fact.
Summary of the invention
For addressing the above problem, the invention provides a kind of high-temperature sealing anchor locking-nuts with twolug.
The objective of the invention is to be achieved by following technical solution.
A kind of high-temperature sealing anchor locking-nuts with twolug, comprise nut body and place the seal closure of nut body outside, described nut body comprises supporting plate, closing in section and is arranged at the screw thread of nut body inside that be provided with sealing gasket in the supporting plate bottom, the section that a closes up outer cover is equipped with seal ring.
Described supporting plate bottom is provided with the groove that sealing gasket is installed.
The outside lower annular groove that seal ring is installed that is provided with of the described section that closes up.
Described seal closure is inner to be provided with the upper annular groove that is complementary with the seal ring external diameter with lower annular groove corresponding section.
Described two ends of bearing plate is provided with mounting hole.
Described seal closure is provided with the through hole that is complementary with mounting hole.
Described seal ring adopts silicone rubber to make.
Described sealing gasket adopts silicone rubber to make.
The invention has the beneficial effects as follows:
Compared with prior art, the present invention is by having increased supporting plate on common ears traveling self-locking nut basis, special silicon rubber loop and sealing gasket have been used, be used by seal closure, seal ring and sealing gasket, rational in infrastructure, formula self-locking nut intensity when being connected with casing is higher, more stable, has greatly improved installation reliability; Have simultaneously good freedom from vibration, locking, high-low temperature resistant, corrosion-resistant.The serviceability temperature scope can reach-50 ℃～+ 300 ℃, effectively provides guarantee to Aeronautics and Astronautics, boats and ships, railway territory liquid, pressure system, oil-way system, has good economic benefit and social benefit, can be in machinery industry wide popularization and application.

Embodiment
Further describe technological scheme of the present invention below in conjunction with accompanying drawing, but that claimed scope is not limited to is described.
Extremely shown in Figure 5 such as Fig. 1, a kind of high-temperature sealing anchor locking-nuts with twolug, comprise nut body 2 and place the seal closure 1 of nut body 2 outsides, described nut body 2 comprises supporting plate 7, closing in section 8 and is arranged at the screw thread 9 of nut body 2 inside, be provided with sealing gasket 4 in supporting plate 7 bottoms, the section that closes up 8 outer cover are equipped with seal ring 3.
Described supporting plate 7 bottoms are provided with the groove 12 that sealing gasket 4 is installed.
Described section 8 outsides of closing up are provided with the lower annular groove 10 that seal ring 3 is installed.
Described seal closure 1 inside is provided with the upper annular groove 11 that is complementary with seal ring 3 external diameters with lower annular groove 10 corresponding sections.
Described supporting plate 7 two ends are provided with mounting hole 5.
Described seal closure 1 is provided with the through hole 6 that is complementary with mounting hole 5.
Described seal ring 3 and sealing gasket 4 all adopt silicone rubber to make.Because silicone rubber has good high-low temperature resistant, chemical-resistance can bear the corrosion of water and number of chemical.
As shown in Figure 6, the present invention in use, first sealing gasket 4 is installed in the groove 12 of nut body 2 bottoms, and seal ring 3 is sleeved in the lower annular groove 10 on the contraction section 8, then seal closure 1 is sleeved on the small end of nut body 2, make the upper annular groove 11 and seal ring 3 no-floats of seal closure 1 inside, by screw 15 whole self-locking nut is fixed on the casing 13 again, is connected by the screw thread 9 in bolt 14 and the nut body 2 at last, so both self-locking nut can be fixed on need to the casing of installation connection on.
Working procedure of the present invention and principle are: the present invention when mounted, high-temperature seal ring, elevated-temperature seal pad are assemblied on the anchor locking-nuts with twolug body specified position, seal closure is positioned at anchor locking-nuts with twolug body small end, seal closure forms seal action to high-temperature seal ring, anchor locking-nuts with twolug body to the extruding of sealing gasket during use, and the anchor locking-nuts with twolug body itself has auto-lock function.So both can form a kind of with high-low temperature resistant and have the anchor locking-nuts with twolug of sealing function.
Self-locking nut of the present invention has used special silicone rubber O-ring and sealing gasket by having increased supporting plate on common ears traveling self-locking nut basis, and has designed the structure of seal closure.Self-locking nut in use anchor locking-nuts with twolug body, seal closure, high-temperature seal ring and the cooperation of elevated-temperature seal pad is more reasonable.Self-locking nut intensity when being connected with casing is higher, more stable, greatly improved installation reliability, the serviceability temperature scope can reach-50 ℃～+ 300 ℃, effectively provide guarantee to Aeronautics and Astronautics, boats and ships, railway territory liquid, pressure system, oil-way system, have good economic benefit and social benefit, can be in machinery industry wide popularization and application.
