The above situation causes great difficulty in electrical overhaul and maintenance, and the personal safety of the overhaul personnel is more difficult to ensure.
Disclosure of Invention
The application aims at providing a structure for positioning and locking a turning cover of an electric coupler, and the existing cover opening fixing and retaining state is solved by designing a positioning structure.
In order to achieve the purpose, the following technical scheme is adopted in the application:
the utility model provides a structure for electric coupler flip location locking, includes coupler flip and casing, coupler flip's side is provided with the locating hole, be provided with the constant head tank on the casing, be provided with the graduation locating pin in coupler flip's the locating hole, the graduation locating pin does not carry out the motion with the casing and interferes.
In the above technical solution, two symmetrical side surfaces of the coupler flip cover are respectively provided with a positioning hole.
In the technical scheme, the shell corresponding to the position of each positioning hole on the coupler flip cover is respectively provided with a positioning groove.
In the technical scheme, the positioning hole on the coupler flip cover is tangent to one side surface of the corresponding positioning groove.
In the above technical solution, at the maximum position of the rotation of the coupler flip, the area of the housing excluding the positioning slot is not included in the positioning hole.
In the technical scheme, the indexing positioning pin is locked by nuts on two sides of the positioning hole.
In the technical scheme, a gap is formed between the tail end of the indexing positioning pin and the side face of the shell, and the tail end of the indexing positioning pin and the side face of the shell are not in contact with each other.
In the technical scheme, at the maximum rotating position of the coupler flip cover, the pin shaft of the indexing positioning pin is inserted into the positioning groove on the shell.
In summary, due to the adoption of the technical scheme, the invention has the beneficial effects that:
the electric coupler flip of partial kind can be solved and can't be fixed behind this application, overhauls the problem of difficulty, has reduced to overhaul and has maintained required manpower, has improved the efficiency of overhauing and maintaining, overhauls the convenience of maintaining and overhauls the security of maintaining.
Drawings
The invention will now be described, by way of example, with reference to the accompanying drawings, in which:
FIG. 1 is a schematic view of the indexing pin installation of the present application;
FIG. 2 is a schematic illustration of a coupler flip cover opening of the present application;
FIG. 3 is a schematic view of the present application of the housing slot
FIG. 4 is a schematic structural diagram of the present application;
wherein: 1 is a coupler flip cover, 2 is a shell, 3 is an index pin, 4 is a positioning hole, and 5 is a positioning groove.
Detailed Description
All of the features disclosed in this specification, or all of the steps in any method or process so disclosed, may be combined in any combination, except combinations of features and/or steps that are mutually exclusive.
Any feature disclosed in this specification (including any accompanying claims, abstract and drawings), may be replaced by alternative features serving equivalent or similar purposes, unless expressly stated otherwise. That is, unless expressly stated otherwise, each feature is only an example of a generic series of equivalent or similar features.
As shown in fig. 4, the schematic view of the overall installation structure of the present embodiment is shown, wherein the coupler flip-cover 1 is directly covered on the housing 2 in the closed state, the coupler flip-cover 1 and the housing 2 are locked and connected by a strong spring member, if the coupler flip-cover 1 needs to be opened, the coupler flip-cover 1 needs to be pulled by a strong pulling force, and then the electrical connection member in the housing 2 can be repaired. Because the structure has certain particularity, in the traditional method, an external device is used for applying acting force to draw the coupler flip cover 1 consistently, and an operator overhauls the inside of the shell 2. This is very cumbersome and carries a certain risk, which is disadvantageous both for the operator and for the operating procedure.
In order to change the problem, the present embodiment utilizes the positioning holes in combination with the positioning pins to solve the problem, and firstly, as shown in fig. 1 and fig. 2, because the coupler flip 1 is a main acted element and is a movable element in the whole process, and because the coupler flip 1 and the housing 2 are connected into a whole, the coupler flip 1 rotates relative to the housing 2, so when considering the positioning holes, the positioning pins must be removed so as not to affect the rotation between the coupler flip 1 and the housing 2.
In the embodiment, a positioning hole 4 is formed in one side of the coupler flip cover 1, and a positioning groove 5 is formed in a position corresponding to the housing 2 when the positioning hole is flipped to the maximum position. Viewed from the side surface of the shell, the positioning hole is tangent to one side surface of the positioning groove, and the part of the shell 2 which is not grooved is not contained in the positioning hole; when the cover is opened to the maximum position, the ungrooved portion of the housing 2 is not contained in the positioning hole.
The two sides of the car coupler flip cover 1 are provided with additional openings respectively, the indexing positioning pins are positioned and fixed in a two-side nut locking mode, so that the handle does not interfere with the electric car coupler in the moving process, and the tail ends of the indexing positioning pins keep a certain gap with the two sides of the electric car coupler shell 2, so that the indexing positioning pins do not interfere with the two sides of the shell 2 in the moving process.
During the use, only need uncap coupling flip 1 to maximum position department when, open index pin 3 according to the user mode, make its round pin axle part fall into 2 both sides constant head tanks of casing, slowly stop applying external force to coupling flip 1 this moment after, coupling flip 1 can keep examining and repairing the position at coupling flip 1 owing to index pin 3's positioning action to be convenient for maintainer overhauls and maintains it.
The invention is not limited to the foregoing embodiments. The invention extends to any novel feature or any novel combination of features disclosed in this specification and any novel method or process steps or any novel combination of features disclosed.
