Abstract
The utility model discloses a combined functional sub-frame metal guide rail, relates to parts of functional sub-frame in optical transmission and optical communication devices. The construction of the utility model is: two ends of the guide rail body are connected to a first guide rail head and a second guide rail head which are in symmetrical construction to each other; the first guide rail is a metal die casting comprising a front head and a rear head; the front head is equipped with an omega-shaped inserting hole, the rear head is equipped with a U-shaped guide rail groove, a horizontal positioning plane, a position hinge, and a circular amounting hole; the guide rail body is a long strip thin-wall metal die casting matching a section with sections of the first and second guide rail head. The utility model is simple in construction, easy to use, making the disc reliably pulled and pushed in the functional sub-frame, and making the disc reach predetermined position precisely, suitable for functional sub-frames of various kinds of communication devices.
Description
Technical field
The utility model relates to the parts of the sub-frame of function in light transmission and the optical communication equipment, relates in particular to the sub-frame metal guide rail of a kind of combined type function.
Background technology
Light transmission and optical communication fast development to the manufacturing and the installation of light transmission and optical communication equipment, are had higher requirement at present.Guide rail is a large amount of key components and partss that use in light transmission and the sub-frame of optical communication equipment function, and the quality of its performance will directly have influence on the reliability of machine dish installation and the accuracy of position, thereby more or less can have influence on the serviceability of the sub-frame of whole functional.At present, the existing in the industry sub-frame of function that is used for is inserted the guide rail of dish and mostly is plastics, exists multiple shortcoming and defect, and is yielding as intensity difference, the poor reliability of installation, and extremely repeatability is also poor the accuracy of machine dish location.
The utility model should far be given birth under this background.
Summary of the invention
The purpose of this utility model just is to overcome the shortcoming and defect that prior art exists, and provides a kind of combined type function sub-frame metal guide rail.
The utility model technical issues that need to address are that the sub-frame of assurance function is inserted the reliability of dish and the accuracy of position.
The purpose of this utility model is achieved in that
In order to guarantee that the machine dish can install reliably in the sub-frame of function, and reach the accuracy in precalculated position, the machine dish plays crucial effects with guide rail especially guide rail head.
Specifically:
The first, guide rail has been taked array mode, so just can come the length of adaline dish, thereby increase its dirigibility by the length of conversion guide rail;
The second, with the important composition parts in the composite guideway---the guide rail head is taked the technology mode of die cast metal moulding, not only have outside self structure intensity and the three-dimensional size precision height, the quality of fit of guide rail head and guide rail is also high.
The utlity model has following advantage and close good effect:
1, simple in structure, easy to use;
2, the machine dish is advanced reliably in the sub-frame of function and pull out, can also make it in the sub-frame of function, reach desired location, and accurate;
3, the utility model is applicable to the sub-frame of function of various communication facilitiess.

Embodiment
Describe in detail below in conjunction with drawings and Examples:
One, overall
As Fig. 1, the utility model comprises 10,20 and guide rails 30 of the 1st, 2 guide rail heads, is connected with the 1st guide rail head 10 and the 2nd guide rail head 20 respectively at guide rail 30 two ends.
Two, parts
1, the 1st guide rail head 10
As Fig. 1,2, the 1 guide rail heads 10 are a kind of bulk metal die castings, comprise front and back;
The front is provided with Ω shape jack 14, and the back is provided with U-shaped guide-track groove 13 and horizontal location face 11, register pin 12 and circular mounting hole 15.
2, the 2nd guide rail head 20
The 2nd guide rail head 20 and the 1st guide rail head 10 be symmetrical structure each other.
3, guide rail 30
As Fig. 1, guide rail 30 is a kind of xsect and the 1st, the adaptive strip metal crimp foundry goods of 2 guide rail heads, 10,20 xsects, comprises Ω shape projection 31 and U-shaped chute 32;
Principle of work of the present utility model is:
Locating surface 11 and register pin 12 are used for the location of the utility model on the sub-frame of function, and its bearing accuracy only is decided by the manufacturing accuracy of compression mod;
Guide-track groove 13 links to each other with U-shaped chute 32, is extended common the composition and specializes in the machine dish advance the guide rail of pulling out in the sub-frame of function, and its guiding accuracy also is that the manufacturing accuracy by compression mod decides;
Jack 14 is joined with Ω shape projection 31 profile cunnings, and its quality of fit still can be decided by the manufacturing accuracy of compression mod;
By screw and mounting hole 15 the utility model is fixedly mounted in the sub-frame of function reliably.Because the geometric accuracy and the position dimension precision of metal crimp foundry goods can reach higher rank, so the utility model is enough to satisfy above requirement, are products that has much practical value.
