The invention discloses a cable hole plugging device for a power cabinet. The cable hole plugging device comprises a trough-type shell, wherein a threading hole is formed in an inner-trough bottom surface of the trough-type shell; the inner-trough bottom surface of the trough-type shell is symmetrically provided with a plurality of groups of slideways in two sides of the threading hole; a slideable adjusting slide plate is arranged in each slideway; rack-shaped clamping teeth are arranged in the middle of the upper surface of each adjusting slide plate; two rotating shafts are symmetrically arranged at two sides in the trough of the trough-type shell; and locating cams are respectively arranged on the rack-shaped clamping teeth on each adjusting slide plate and are used for achieving a location after the adjusting slide plates adjust. The cable hole plugging device for the power cabinet has the beneficial effects of being simple in structure and convenient to use; a gap after threading of the threading hole can be reduced to the minimal size by adjusting the size of the threading hole through the adjusting slide plates; the adjusting slide plates can be located by rotating the locating cams by the clamping teeth in the upper surfaces of the adjusting slide plates; a threading opening can be tightly plugged by matching with fireproofing mud; the fireproofing mud can be prevented from leaking through a support of the trough-type shell; the cable hole plugging device can be repeatedly used; and the use cost is low.
Description
Technical field
The present invention be more particularly directed to a kind of power screen cabinet plugging cable hole device.
Background technology
Power screen cabinet, in use for the ease of threading, arranges larger threading opening usually in the bottom surface of power screen cabinet, in order to the space stayed after shutoff threading, usually uses fire-proof mud shutoff threading opening after current threading.There are the following problems for this shutoff mode:
1, because threading opening is comparatively large and without supporting below fire-proof mud, long fire-proof mud easily spilt and lost plugging action the time one, made threading opening blank, easily caused the toys such as mouse to enter, thus accidents caused.
2, this shutoff mode belongs to disposable shutoff, and when the power screen cabinet after shutoff needs to increase cable, the fire-proof mud of shutoff can only be removed completely, after threading, shutoff again again, wastes time and energy.
Summary of the invention
It is simple that technical problem to be solved by this invention is to provide a kind of structure, easy to use, and shutoff is tight, and fire-proof mud can be avoided to spill, and increases the power screen cabinet plugging cable hole device that cable is time saving and energy saving.
For solving the problem, the present invention adopts following technical scheme:
A kind of power screen cabinet plugging cable hole device, it has a grooved housing, a through wires hole is provided with in the middle part of the groove inner bottom surface of grooved housing, be positioned at through wires hole bilateral symmetry at the groove inner bottom surface of grooved housing to be provided with and to organize slideway more, slidably adjusting slider is respectively equipped with in each slideway, longitudinally spline-simulating card tooth is provided with along it in adjusting slider upper surface middle part, in the groove of grooved housing, bilateral symmetry is provided with two rotating shafts, spline-simulating Ka Yachu in rotating shaft on corresponding each adjusting slider is respectively equipped with positioning cam, for realizing the location after adjusting slider adjustment.
As preferred further, described grooved housing is hinged by two housings to form.
As preferred further, be respectively equipped with rectangle gap in corresponding side, the bottom surface of two housings, described through wires hole is rectangle and is made up of the rectangle gap of two housings.
As preferred further, described rotating shaft is fixed in grooved housing by axle bed compressing tablet.
As preferred further, described slideway quantity is four groups.
As further preferably, before and after two housings both sides facade on its rectangle gap one end corresponding be respectively equipped with the arc convex and arc groove that cooperatively interact, for being hinged of two housings.
As preferred further, three facades of each housing are respectively equipped with tearable breach, and each tearable breach is formed by the three tearable lines laying respectively at both sides and bottom.
As preferred further, described grooved housing and adjusting slider are made by insulating material.
The invention has the beneficial effects as follows:
1, structure is simple, easy to use, regulate the size of through wires hole the space after through wires hole threading can be decreased to minimum by adjusting slider, then rotate positioning cam and utilize the card tooth of adjusting slider upper surface just adjusting slider can be located, coordinate fire-proof mud just can by tight for threading opening shutoff; And fire-proof mud can be avoided to spill by grooved housings support.
Reverse rotation positioning cam release regulation slide plate is only needed when 2, increasing cable, again with adjusting slider gap mutually corresponding in the tool inserting slot-in type housings such as screwdriver and the hole rotating cable size can insert cable, without the need to re-using fire-proof mud shutoff, time saving and energy saving.
3, reusable, use cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the A-A cutaway view of Fig. 2.
In figure: grooved housing 1, tearable line 2, arc groove 3, tearable breach 4, slideway 5, adjusting slider 6, spline-simulating card tooth 601, arc convex 7, through wires hole 8, rotating shaft 9, positioning cam 10, axle bed compressing tablet 11.
Embodiment
As shown in Figure 1-Figure 3, a kind of power screen cabinet plugging cable hole device that the present invention relates to, it has a grooved housing 1, a through wires hole 8 is provided with in the middle part of the groove inner bottom surface of grooved housing 1, be positioned at through wires hole 8 bilateral symmetry at the groove inner bottom surface of grooved housing 1 and be provided with many group slideways 5, in each slideway 5, be respectively equipped with slidably adjusting slider 6, adjusting slider 6 coordinates with slideway 5 glade plane space.Longitudinally be provided with spline-simulating card tooth 601 in adjusting slider 6 upper surface middle part along it, in the groove of grooved housing 1, bilateral symmetry is provided with two rotating shafts 9, and described rotating shaft 9 is fixed in grooved housing 1 by axle bed compressing tablet 11.Spline-simulating card tooth 601 place in rotating shaft 9 on corresponding each adjusting slider 6 is arranged with positioning cam 10 respectively, after positioning cam 10 rotates, its outer rim may be stuck on the spline-simulating card tooth 601 on corresponding adjusting slider 6, for realizing the location after adjusting slider 6 adjustment.
