Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: a combined screw for a railway comprises a screw head 1 and a screw column 8, a cross knife edge 5 is arranged above the screw head 1, a magnetic film 9 covers one layer of the upper end surface of the screw head 1, a gasket 2 is arranged below the screw head 1, a nut 3 is fixedly connected below the gasket 2, a thread 4 is arranged below the screw head 1, the screw column 8 is arranged inside the thread 4, a support plate 6 is arranged inside the screw column 8, and antirust sticking films 7 are arranged on one layer of the upper end surface and one layer of the lower end surface of the support plate 6.

The utility model discloses in: the cross knife edge 5 and the screw head 1 are of an integrated structure, and the upper surface of the screw head 1 is tightly attached to the lower surface of the magnetic film 9; through the screwhead 1 and the cross edge of a knife 5 that set up, it is that the user can use multiple instrument to be used for the installation of screw fixed no longer to confine to single screwdriver or adjustable spanner, through the magnetic film 9 with the tight laminating in screwhead 1 top one deck surface, makes the user screwhead 1 can adsorb on screwhead of a knife or adjustable spanner better when using screwdriver or adjustable spanner installation set screw, can not drop when the installation, very big improvement the installation effectiveness of screw.

The utility model discloses in: the gasket 2 and the nut 3 are of an integrated structure, and the nut 3 and the screw column 8 are of a detachable structure; through the structure between nut 3 and the screw post 8 that sets up, make the screw at the fixed in-process, delete the method of single screw fixation in the past, use nut 3 to carry out the secondary and fix, very big reinforcing the fixed intensity of screw, and with the nut 3 between the gasket 2 of formula structure as an organic whole make nut 3 separate with the sleeper that needs to fix, greatly reduced nut 3's wear rate has improved the holistic life of screw.

The utility model discloses in: the support plate 6 is fixedly connected with the screw column 8, the support plate 6 is bent, and the support plate 6 is tightly attached to the antirust film 7; through the backup pad 6 that the form of buckling is set up in screw post 8 inside, let screw post 8 closely link to each other with backup pad 6, make the vibrations that receive at fixed in-process screw can be through backup pad 6 even every position of dispersion to the screw, strengthened the shock resistance of screw itself, reduce the probability that the screw drops when the train passes through.

The utility model discloses in: the screw head 1 and the screw column 8 are connected in a welding manner, and the thread 4 and the screw column 8 are in an integrated structure; through setting up the connected mode between screwhead 1 and the screw post 8, the fixed strength of screw itself has been improved greatly, screw post 8 is connected more easily at fixed in-process screwhead 1, the cracked risk of screw itself has been reduced, it is more convenient to make reciprocating of nut 3 through the screw thread 4 that sets up, it is relatively convenient to make the fixed process of installation, and screw thread 4 and screw post 8 formula structure as an organic whole, be fixed in screw post 8 top that nut 3 can be better, strengthen the fixed strength of screw at the in-process of fixed rail and sleeper.

The utility model discloses in: the internal dimension of nut 3 is identical with the external dimension of screw post 8, and the diameter ratio between gasket 2 and nut 3 is 1: 1; through setting up nut 3 and the size of screw post 8, make nut 3 can be better through 4 blocks of screw thread on screw post 8, set up the diameter length of gasket 2 and nut 3, make gasket 2 and nut 3's area of contact equal, reduced nut 3's wear rate, increased the life of screw.

The working principle of the screw for the combinable railway is as follows: firstly, the nut 3 can be detached from the screw column 8 through the thread 4, then a user fixes the thread 4 below a sleeper, and the screw column 8 penetrates through the sleeper through a rail and is rotatably connected to the nut 3 through a screwdriver or a monkey wrench, so that the fixing strength of the screw can be effectively improved through the double-layer fixing;

secondly, when a user starts to use a screwdriver or a monkey wrench to rotate the screw, the magnetic film 9 which is tightly attached to the surface of the screw head 1 can enable the screw to be well adsorbed on the screwdriver or the monkey wrench, so that the installation time of the user is greatly reduced; secondly, when the train passes through the rail, the vibration generated when the train wheel impacts the rail can be gradually transmitted to the supporting plate 6 inside the screw, and the shape of the supporting plate 6 is set, so that the vibration generated when the train wheel impacts the rail can be uniformly transmitted to each part of the screw, and the service life of the screw is prolonged; then when a user rotates the nut 3 to the screw column 8, the gasket 2 arranged on the nut 3 can effectively isolate the contact between the nut 3 and a sleeper, so that the friction between the nut 3 and the sleeper is reduced, and the wear rate of the nut 3 is reduced;

last backup pad 6 is gone up rust-resistant pad pasting 7 of inseparable laminating, can effectively completely cut off backup pad 6 and external contact, prevents because the soaking screw of rainwater leads to the corrosion of backup pad 6, increases the life of backup pad 6, also is increasing the life of screw.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
