Abstract
The utility model relates to a kind of useless row and installs disconnecting prevention structure, composition comprises the bolt for fixing useless exclusive shell, useless exclusive shell is welded with fixed base, fixed base is placed with stopping shim, bolt is threaded with fixed support through stopping shim and fixed base, stopping shim has downward bending for catching on the blade of fixed base sidewall, and is suitable for the plectrum that upwards bends for propping up bolt head side.Be stuck in by the blade of stopping shim on the fixed base of useless row's welding, plectrum is stuck on clamping bolt in addition, effectively suppresses screws, realizes anti-drop function.
Description
Technical field
The utility model relates to useless row and installs disconnecting prevention structure.
Background technique
The useless row that current railcar is installed is bolted on roof, and do not have disconnecting prevention structure, installation reliability is lower.Finding through inspection, in the disconnecting prevention structure of existing bolt, some use end face ratchets or similar means destroy and realize retaining with the surface of contact of nut; Some use wedge-shaped bar embed in screw thread, realize the locking of nut.Above-mentioned disconnecting prevention structure all needs special tool to install or removes, and the cost being directly diverted to useless row is higher.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the above-mentioned shortcoming of prior art, provides a kind of useless row to install disconnecting prevention structure.
In order to solve above technical problem, the useless row that the utility model provides installs disconnecting prevention structure, composition comprises the bolt for fixing useless exclusive shell, it is characterized in that: useless exclusive shell is welded with fixed base, described fixed base is placed with stopping shim, described bolt is threaded with fixed support through stopping shim and fixed base, and described stopping shim has downward bending for catching on the blade of fixed base sidewall, and is suitable for the plectrum that upwards bends for propping up bolt head side.
The utility model also has following improvement:
1, have the plectrum described in two, the angle of two plectrums is 90 °.
2, described bolt is hexagon head bolt.
3, described fixed base has two parallel sides.
Be stuck in by the blade of stopping shim on the fixed base of useless row's welding, plectrum is stuck on clamping bolt in addition, effectively suppresses screws, realizes anti-drop function.
During installation, seat is welded and fixed at useless exclusive shell mounting points place, stopping shim placed by fixed base, the blade of stopping shim catches on a sidewall of fixed base, clamping bolt is arranged on after on fixed support through stopping shim and useless exclusive shell, digs stopping shim plectrum, makes plectrum catch on a side of hex head bolt, effective suppression screws, realizes anti-drop function.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is that the useless row of the utility model installs disconnecting prevention structure plan view.
Fig. 2 is that the useless row of the utility model installs disconnecting prevention structure sectional view.
1-bolt; 2-fixed base; 3-stopping shim, 4-fixed support, 5-blade, 6-plectrum, 7-gives up exclusive shell.
Embodiment
As Fig. 1, shown in Fig. 2, the useless row of the present embodiment installs disconnecting prevention structure, composition comprises the bolt 1 for being installed on by useless exclusive shell 7 on fixed bearing 4, useless exclusive shell 7 is welded with fixed base 2, fixed base 2 has two parallel sides, fixed base 2 is placed with stopping shim 3, bolt 1 is threaded with fixed support 4 through stopping shim 3 and fixed base 2, stopping shim 3 has downward bending for catching on the blade 5 of fixed base 2 sidewall, and be suitable for upwards bending two plectrums 6 for propping up bolt head side, the angle of two plectrums is 90 °, after can bolt tightening being guaranteed like this, adjust at most by a small margin and plectrum can be made to lean on mutually with bolt head side.In this example, bolt uses hexagon head bolt.
During installation, seat 2 is welded and fixed at useless exclusive shell 7 mounting points place, fixed base 2 is placed stopping shim 3, the blade 5 of stopping shim 3 catches on a sidewall of fixed base, clamping bolt 1 is arranged on after on fixed support 4 through stopping shim 3 and useless exclusive shell 7, digs stopping shim 3 one plectrums, makes plectrum catch on a side of hex head bolt, effective suppression screws, realizes anti-drop function.
In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
