Abstract
A pre-buried iron base used for a self-locking elastic strip is composed of a base body (12) and an embedded limb (11) connected to the bottom of the base body (12), an inserting hole (5) and a supporting platform (6) are arranged on the base body (12), and the supporting platform (6) is positioned on one side of the inserting hole (5). The pre-buried iron base used for the self-locking elastic strip is characterized in that a first boss (7) is arranged on the inner wall of the inserting hole (5), a first hooking face (8) is arranged on the side portion of the first boss (7), and the first hooking face (8) enables the first boss (7) to form an overhead hook structure. A second boss (9) is arranged on the supporting platform (6), a second hooking face (10) is arranged on the side portion of the second boss (9), and the second hooking face (10) enables the second boss (7) to form an overhead hook structure. The first hooking face (8) of the first boss (7) and the second hooking face (10) of the second boss (9) both face toward the inserting direction of the inserting hole (5). The pre-buried iron base used for the self-locking elastic strip effectively solves the problem that in the prior art, steel rail elastic strips are prone to being stolen.
Description
Technical field
The utility model relates to rail on the railroad track and the connector of sleeper, is specifically related to a kind of self-locking spring preburied iron base.
Background technology
The structure of existing preburied iron base is referring to shown in the accompanying drawing 1, by imbedding limb 1 and pedestal 2 is formed, imbedding limb 1 is used for imbedding in the concrete sleeper, pedestal 2 is provided with for the patchhole 3 of pegging graft with the spring limb and is used for brace table 4 with the crimping of spring heel end, and this preburied iron base cooperates with spring and is formed on the sleeper the fixedly elastic bar fastener of rail.Do not have buckle structure or snap close effect bad in real life because between preburied iron base and the spring, the stolen situation of spring often takes place, cause traffic safety hidden danger, influence the normal operation of railway.
Summary of the invention
The utility model provides a kind of self-locking spring preburied iron base, its be to solve that spring is easy to stolen problem in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of self-locking spring preburied iron base, constituted by pedestal and the limb of imbedding that is connected pedestal bottom, described pedestal is provided with patchhole and brace table, brace table is positioned at a side of patchhole, its innovation is: the inwall of described patchhole is provided with first boss, and the sidepiece of first boss is provided with the first hook face, and the first hook face makes first boss form overhead structure; Described brace table is provided with second boss, and the sidepiece of second boss is provided with the second hook face, and the second hook face makes second boss form overhead structure; The first hook face of described first boss and the second hook face of second boss are all towards the direction of insertion of patchhole.
In the technique scheme, described direction of insertion refers to the c direction.
The utility model operating principle and beneficial effect are: be provided with first boss in the patchhole with the utility model preburied iron base, first boss is provided with the first hook face, be provided with second boss at brace table, second boss is provided with the second hook face, this preburied iron base is when corresponding self-locking spring is connected, first boss and second boss are embedded in respectively in the recess of corresponding self-locking spring, and make the prevention wall interlock of win hook face and the second hook face and self-locking spring recess, has the twin-lock buckle structure, therefore after preburied iron base and corresponding self-locking spring connection, can effectively prevent the stolen problem of spring, also have the advantage that prevents that spring from coming off simultaneously, guaranteed traffic safety.
