Description
Technical field
The present invention relates to technical field of communication equipment, and in particular to a kind of machine disk that structure is lifted with push-key.
Background technique
In modern communications equipment, plug-in machine disk is largely widely applied, and the component must be by push-key appropriate
Device could complete the plug operation of machine disk；
In existing transverse-plug type communication equipment, due to gravity and reasonable clearance factor, in the presence of machine disk push-key is inevitable
Vertical phenomenon, and influenced by technique manufacture, such sagging amplitude is difficult to stability contorting, and push-key often exceeds the profile model of itself machine disk
It encloses, and then stops the inserting of the adjacent machine disk in lower section, scrape component in damage disk under；
Therefore, it is badly in need of a kind of machine dish structure that can lift push-key.
Summary of the invention
In view of the deficiencies in the prior art, the purpose of the present invention is to provide a kind of machines that structure is lifted with push-key
Disk lifts structure using first and raises the minimum point of push-key, avoids the minimum point of push-key from scratching lower section electronic component, protects machine
Electronic component on disk is injury-free.
To achieve the above objectives, the technical solution adopted by the present invention is that:
A kind of machine disk for lifting structure with push-key, the machine disk include:
Machine disc main body；
Erect the machine disk vertical plate in machine disc main body side:
At least one push-key socket, the push-key socket is arranged on the machine disk vertical plate, and the push-key socket bottom
Structure is lifted equipped with first, and described first when lifting structure for making the push-key latch hook head of push-key be inserted into the push-key socket, institute
The minimum point for stating push-key is higher than the lower edge of the machine disc main body.
Based on the above technical solution, quantity and the push-key socket consistent the are provided on the machine disc main body
Two lift structure, and each described second lifts structure and each push-key socket pairing；
Described second lifts on the rotation path of turning end of the structure setting in the push-key, for making the institute of the push-key
When stating the push-key latch hook head insertion push-key socket, the minimum point of the turning end of the push-key is higher than the following of the machine disc main body
Edge.
Based on the above technical solution, second structure is lifted as spherical structure.
Based on the above technical solution, described first structure is lifted as bevel structure, described first lifts structure use
When the push-key latch hook head of push-key is inserted into the push-key socket, the push-key latch hook head is lifted, so that the minimum point of push-key is higher than
The lower edge of the machine disc main body.
Based on the above technical solution, described first structure is lifted close to the side of push-key socket higher than described first
Lift side of the structure far from the push-key socket.
Based on the above technical solution, described first structure is lifted as U-shaped protrusion, described first, which lifts structure, is used for
When the push-key latch hook head of push-key is inserted into the push-key socket, the push-key latch hook head is lifted, so that the minimum point of push-key is higher than institute
State the lower edge of machine disc main body.
Based on the above technical solution, the described first top for lifting structure is planar structure.
Based on the above technical solution, described first structure is lifted as elastic head lifting part, described first lifts knot
When push-key latch hook head of the structure for push-key is inserted into the push-key socket, the push-key latch hook head is lifted, so that the minimum point of push-key
Higher than the lower edge of the machine disc main body.
Based on the above technical solution, it described first lifts structure and includes:
The elastic panel on the machine disc main body is arranged in one end；
Lifting in protrusion for the free end of the elastic panel is set；
When the push-key latch hook head that protrusion is lifted for the push-key is inserted into the push-key socket, described pull is lifted
Key-lock gib head, so that the minimum point of the push-key is higher than the lower edge of the machine disc main body.
Based on the above technical solution, the protrusion of lifting is spherical structure.
Compared with the prior art, the advantages of the present invention are as follows:
(1) present invention lifts structure using first and raises the minimum point of push-key, and the minimum point of push-key is avoided to scratch lower section
Electronic component protects the electronic component on machine disk injury-free.
