For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6 and Fig. 7, be respectively labeled as in figure: 1 is cover board body, and 2 is arm-tie, and 3 is elastic strip, and 11 is stator, and 21 is pull bar.
As depicted in figs. 1 and 2, adjustable cable channel cover plate in the Part I of the present embodiment, specifically includes: cover board body 1, arm-tie 2 and stator 11.
The concrete syndeton of the present embodiment is:
Cover board body 1 has case structure, and the one end open of cover board body 1, so that arm-tie 2 can be inserted by this opening and skid off cover board body 1.
Also be provided with slide rail in the inside of cover board body 1, connect arm-tie 2 by this slide rail, make arm-tie 2 can carry out under the effect of slide rail convenient, move smoothly.
Concrete, in the present embodiment, slide rail specifically can select the cooperation into sliding-rail groove and slide bar, namely on the contact-making surface of the inside of cover board body 1 connection arm-tie 2, sliding-rail groove is provided with, and be provided with on the long limit of arm-tie 2 with this sliding-rail groove with the use of slide bar, to ensure that the relative motion of cover board body 1 and arm-tie 2 is convenient by slide bar with coordinating of sliding-rail groove.
Further, in slide rail, be also provided with multiple holddown groove, so that in the process pulling arm-tie 2, can be fixed arm-tie 2 by holddown groove, the adjustable cable channel cover plate of the present embodiment can effectively can be adapted to for different situations.
Further, in the present embodiment, slide rail can adopt 7603T type three to save heavy type and entirely extract slide rail out, and this slide rail, with positioning function, effectively can realize slip and the location of arm-tie 2.
Stator 11 is articulated and connected on the surface of cover board body 1 for covering cable ditch, the lower surface of such as cover board body 1 geared cable ditch inside in the present embodiment, stator 11 is connected with arm-tie 2 simultaneously, when pulling arm-tie 2, when pulling out cover board body 1 by arm-tie 2, drive stator 11 rotates by arm-tie 2, stator 11 will stretch out the lower surface of cover board body 1 simultaneously, to be contacted with cable trough by the stator 11 stretched out, cover board body 1 can be connected with cable trough more closely, ensure the effective shutoff of cable trough.
Further, one end of the non-cylinder lever connecting rod of stator 11 21 is greater than stator 11 and the length of cover board body 1 pin joint to the cover board body 1 long limit nearest with this pin joint, so that stator 11 partly can expose the lower surface of cover board body 1 after rotation to stator 11 and the length of the position of cover board body 1 pin joint.
Further, by elastic strip 3 being connected on the edge of cover board body 1 and arm-tie 2, such as cover board body 1 does not connect on three sides of arm-tie 2, and arm-tie 2 free end, further can be ensured the compactness of cable trough shutoff by elastic strip 3, ensure that the shutoff of cable trough is more effective.
Further, arm-tie 2 is plate construction, and all connects elastic strip 3 in the edge of arm-tie 2, makes arm-tie 2 can be tightr with the contact of cover board body 1, can shake after preventing arm-tie 2 to be connected with cover board body 1, affect the performance of cable trough shutoff.Described elastic strip 3 is flexibel polyurethane foaming elastomer; The elastic strip of cover board body 1 periphery is pasted on all sidewalls of cover board body 1 except opening, has the width of 30-50 millimeter and the thickness of 10-30 millimeter; The elastic strip of arm-tie 2 periphery pastes upper surface at arm-tie 2 except reserving in arm-tie 2 both sides the part contacted with slide rail towards all edges except cover board body 1 opening, there is the width of 40-60 millimeter and the thickness of 5-20 millimeter, and may be folded on arm-tie 2 to take in together with arm-tie 2 in cover board body 1; After arm-tie 2 pulls out cover board body 1, the elastic strip of cover board body 1 and arm-tie 2 periphery forms the continuous strip around cover board body 1 and arm-tie 2.
As shown in Figure 3, be the rearview of the present embodiment, in the present embodiment, stator 11 can be multiple, and the mode of stator 11 according to two one group is connected on the lower surface of cover board body 1 respectively by articulated manner.
Further, arm-tie 2 is also connected with pull bar 21, pull bar 21 is also connected and fixed sheet 11 simultaneously, together to drive pull bar 21 in the process of arm-tie 2 motion, stator 11 also can be driven together to rotate when pull bar 21 moves simultaneously.
When arm-tie 2 inserts the inside of cover board body 1, the free end face of stator 11 is to arm-tie 2, when arm-tie 2 is pulled out cover board body 1, arm-tie 2 drives the outside of pull bar 21 1 cover board body 1 in the same way to move, simultaneously pull bar 21 can drive and be attached thereto the stator 11 connect and rotate with the pin joint of stator 11 in the process of movement, to make stator 11 will stretch out in the scope of cover board body 1 after rotation, further fix to contact cable trough by stator 11.
Separately, the mounting means of stator 11 also can adopt other forms, such as contrary with the present embodiment direction, or is connected by slide rail, and drives stator 11 to slide when pull bar 21 is moved, and makes stator 11 skid off cover board body 1.
Further, multiple stator 11 is by rope cylinder lever connecting rod 21, wherein, being arranged at two stators 11 corresponding on the long limit of cover board body 1 lower surface two is connected in the same point on pull bar 21, so that while control pull bar 21 moves, pull bar 21 can drive two mutually corresponding stators 11 together to carry out the rotation of equal angular, and two mutually corresponding stators 11 respectively with the tie point of cover board body 1 for initial point carries out clockwise or counterclockwise rotation.
Further, lower surface two long limits of cover board body 1 also can be respectively arranged with boss, and this boss is positioned at the inside with stator 11 tie point on cover board body 1, so that after stator 11 rotates back cover board body 1 lower surface, carry out spacing by boss to stator 11, the scope preventing stator 11 from rotating is excessive, affects the fixed effect of stator 11.
Further, the free end of arm-tie 2 also can be provided with the lug boss that thickness is greater than arm-tie 2 body thickness, such as, the thickness of this lug boss is 2cm, makes the more convenient to operate of arm-tie 2 by this lug boss.
Further, cover board body 1 and arm-tie 2 can adopt polymer composite insulating material to make, make cover board body 1 and arm-tie 2 in the process of application, there is better operating characteristic, prevent operational environment from causing damage to it, its insulation property can also effectively prevent staff from getting an electric shock simultaneously, ensure construction safety.
Further, the upper surface of cover board body 1 also can connect warning indicate, what this warning mark was upright is connected on the upper surface of cover board body 1, the two sides, front and back of this warning mark simultaneously has face respectively, so that after the good cable trough of shutoff, effectively can point out through personnel, prevent contingency.
