Abstract
The invention relates to a cable sealing frame with four closed sides, which is applied to the field of cable module sealing. The previously adopted frame applies small pressing force to a module or the deformation of a pressing block is not large enough, only about 2mm frequently, so that the pressing force is small; and the four sides of the frame are closed, so that a cable sealing module is installed strenuously and even cannot be installed to cause failure of product application. By a mode of matching two wedge blocks which do up-and-down motion with a trapezoid wedge block, the trapezoid wedge block can do transverse motion, so that larger deformation is provided, and the installation space and sealing pressure are relatively increased; therefore, the frame with the four closed sides can provide larger pressing force and higher deformation capacity.
Description
Affiliated technical field
The present invention relates to a kind of circumferential closed cable seal frame, be applied to the cable crossing seal field, the seal modules in the framework is seen other module sealing patents, does not do description here.
Technical background
The present invention is applied to module sealing; The framework that adopts of past is big inadequately to the distortion of compact heap in other words of the impacting force deficiency of module; Often has only the distortion of 2 millimeter; Thereby the deficiency that causes impacting force; And because framework is circumferential closed; Thereby require great effort very much when causing cable sealing module is installed, or even can't install, thereby the failure that causes product to be used; A kind of two voussoirs and mode that trapezoidal voussoir matches that moves up and down of this novel employing; Trapezoidal voussoir can transverse movement; Thereby bigger distortion is provided; Installing space is relative with sealing load to be increased, thereby makes circumferential closed framework that bigger impacting force and deformability also can be provided.
Summary of the invention
In order to overcome traditional framework very inconvenience is installed, the problem that sealing load is little has proposed this novel frame structure, can effectively address these problems.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is a kind of circumferential closed cable seal frame explosive view.
Fig. 2 is a kind of circumferential closed cable seal frame plane view.
As shown in Figure 1; A kind of circumferential closed cable seal frame; It is characterized in that: a circumferential closed block structure 1 that has flange edge 9 (flange edge can be removed when being welded to casing), the centre hollows out places seal modules, keeps a part as antetheca at front surface; Side footpath round head screw 2 passes the square tube hole on the antetheca of housing 1, perhaps directly self-clinching standoff on antetheca; Screw passes the last wedge-shaped blocks 3 and following wedge-shaped blocks 4 that moves up and down, and is added in the trapezoidal wedge-shaped blocks 5 between wedge-shaped blocks 3 and the following wedge-shaped blocks 4, and then passes press table 6, uses nut screwing clamping again; At this moment trapezoidal wedge-shaped blocks 5 transverse movements, thereby the cable seal in the compact heap body structure, thereby hermetically-sealed cable.
Inside, block structure 1 corner has gets stuck 10, when putting into cable sealing module, can hold module.If need the blasting resistance structure of two-sided anti-pulling; Then need the flange edge bottom surface to flush (being the waist of flange edge among the figure) with the framework bottom surface at framework; Flange edge bottom surface and rack surface are adjacent to; Rear of cabinet increases by one and has identical opening with framework; But increase some the protruding cover plate of certain intervals is arranged, allow half to put into framework (with reference to CN200920157061.3) between the adjacent protrusion.
Wedge-shaped blocks 5 has a waist hole, and permission screw when the wedge-shaped blocks transverse movement passes.
Antetheca can be cancelled under another situation, increases a pressing plate and substitutes antetheca, goes up press table like this, and wedge-shaped blocks and trapezoidal wedge-shaped blocks constitute (nut can use tapping on press table, to substitute) hold down gag jointly up and down, directly place block structure.
As shown in Figure 2, a kind of plane view of circumferential closed cable seal frame is in order better to understand this novel structure.
Adopt the present invention both to satisfy the good requirement of outward appearance, bigger rock deformation pressure is provided again, it is also easy much to install.
Claims (5)
1. circumferential closed cable seal frame, it is characterized in that: a circumferential closed block structure, centre hollow out places seal modules, keeps a part as antetheca at front surface; Side footpath round head screw passes the square tube hole on the antetheca of housing, perhaps directly presses screw on antetheca; Screw passes the last wedge-shaped blocks and following wedge-shaped blocks that moves up and down, and is clipped in the trapezoidal wedge-shaped blocks between wedge-shaped blocks and the following wedge-shaped blocks, and then passes press table, uses nut screwing clamping again; At this moment trapezoidal wedge-shaped blocks transverse movement.
2. the circumferential closed cable seal frame of telling according to claim 1, it is characterized in that: inside, shell construction corner has gets stuck; If need the blasting resistance structure of two-sided anti-pulling; Then need the flange edge bottom surface to flush with the framework bottom surface; Flange edge bottom surface and rack surface are adjacent to; Rear of cabinet increases by one and has identical opening with framework; But increase some the protruding cover plate of certain intervals is arranged, allow half to put into framework between the adjacent protrusion.
3. the circumferential closed cable seal frame of telling according to claim 1, it is characterized in that: the trapezoidal wedge-shaped blocks of being told has a waist hole, allows that screw passes when the wedge-shaped blocks transverse movement.
4. the circumferential closed cable seal frame of telling according to claim 1 is characterized in that: the same wedge-shaped blocks of being told of trapezoidal wedge-shaped blocks is the inclined-plane with the surface of contact of following wedge-shaped blocks.
5. the circumferential closed cable seal frame of telling according to claim 1; It is characterized in that: antetheca can be cancelled, and increases a pressing plate and substitutes antetheca, goes up press table like this; Wedge-shaped blocks and trapezoidal wedge-shaped blocks constitute hold down gag jointly up and down, directly place block structure.
