Abstract
The utility model discloses a turnbuckle for a joint between grab rails of railway vehicles. The turnbuckle for the joint between the grab rails of the railway vehicles comprises a hollow body with an opening at one end of the hollow body, threads are arranged on the inner wall of the body and an end packaging mechanism with smooth surface is fixed on the closed end of the body. The turnbuckle for the joint between the grab rails of the railway vehicles has the advantages of being capable of solving problem of scratching passengers when bolts or screws get out of nuts and enabling the surface of the joint to be more attractive.
Description
Technical field
The utility model relates to a kind of metal fastenings, particularly a kind of threaded bush for joint between the rail traffic vehicles grab bar.
Background technique
At present, generally adopt T connector or cross-over joint to connect between the urban rail transit vehicles grab bar, be used fastening with bolt or screw and conventional nut.For so that the connection effect of grab bar is attractive in appearance, that usually joint is done is very little, attractive in appearance with regard to affecting so that bolt or screw expose the nut surface usually like this, and the part of exposing simultaneously the nut surface is the scratch passenger very easily.
Summary of the invention
Technical problem to be solved in the utility model is, and is not enough for prior art, and a kind of threaded bush for joint between the rail traffic vehicles grab bar is provided, and solves the problem that bolt or screw expose nut surface scratch passenger, makes joint surface more attractive in appearance.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of threaded bush for joint between the rail traffic vehicles grab bar,, comprising the hollow body of an end opening, described inner body wall is provided with screw thread; Described body not opening one end is fixed with ganoid end portion encloses mechanism.
As preferred version, described end portion encloses mechanism comprises the flange plate that is fixedly connected with body, and described flange plate is provided with equally distributed tooth near a side of described body.
The profile of body can be cylindrical body or cuboid, establishes internal thread at threaded bush's body, and the specification of internal thread can design according to the bolt or the screw model that adopt.
Compared with prior art, the beneficial effect that the utility model has is: the utility model has solved bolt or screw exposes nut surface scratch passenger's problem, makes joint surface more attractive in appearance.
Description of drawings
Fig. 1 is the utility model one example structure schematic representation.
Embodiment
As shown in Figure 1, the utility model one embodiment comprises the hollow body 1 of an end opening, and described body 1 inwall is provided with screw thread 2; Described body 1 not opening one end is fixed with flange plate 3, and described flange plate 3 is provided with equally distributed tooth 4 near a side of described body 1.
The profile of body 1 can be made cylindrical body or cuboid.
The material of flange plate 3 is stainless steel.
This threaded bush usually and socket head screw be used, when fastening, the threaded bush can be penetrated in the perforate of joint, socket head screw is penetrated from the other end of joint tighten again.When the threaded bush is fitted on the joint, continue rotary screw, the contacted tooth of threaded bush and joint surface embeds joint surface, and therefore the frictional force between threaded bush and the joint can increase.Like this, when the threaded bush is subject to than strong vibration, still can have comparatively ideal anti-loosening property.
Claims (3)
1. a threaded bush who is used for joint between the rail traffic vehicles grab bar is characterized in that comprise the hollow body (1) of an end opening, described body (1) inwall is provided with screw thread (2); Described body (1) not opening one end is fixed with ganoid end portion encloses mechanism.
2. the threaded bush for joint between the rail traffic vehicles grab bar according to claim 1, it is characterized in that, described end portion encloses mechanism comprises the flange plate (3) that is fixedly connected with body (1), and described flange plate (3) is provided with equally distributed tooth (4) near a side of described body (1).
