Abstract
The present invention discloses an indoor wire layout clamp which comprises a bottom plate and a plurality of pressing plates. A center rod is fixed at the middle of the bottom plate. The plurality of pressing plates are rotatingly arranged on the center rod. The side wall of each of the pressing plates is provided with a U-shaped groove. The two sides of the inner wall of the U-shaped groove are equipped with elastic projections. A clamping rod corresponding to the U-shaped groove is fixed to the bottom plate. When an optical cable circuit layout is changed, only the removal of the center rod and the fastener at the upper end of the clamp rod is needed, at the same time the pressing plates are rotated reversely, the separation of the pressing plates and a plurality of stacked optical cables can be realized, the flow of taking a pressing plate from two screws one by one in optical cable circuit change is avoided, and the possibility of cable damage in the pressing plate removal process is reduced.
Description
Technical field
The present invention relates to a kind of optical cable, specifically refer to a kind of house wiring cable clamp.
Background technology
Inside cable is the optical cable be laid in buildings, is mainly used in the communication facilities in buildings, computing machine, the equipment etc. of switch and terminal user, so that transmission of information.Inside cable is the cable formed through certain technique by optical fiber (optical transmission carrier), inside cable is formed primarily of light transmitting fiber and plastic protective sleeve pipe and plastic peel, without gold in optical cable, silver, the metals such as copper aluminium, therefore when indoor optical cable wiring, the fibre core beam tube of optical cable can not twisting, namely in the process of fixing multiple bundle cable, fixture is generally multiple pressing plate be arranged side by side, and the layer structure of rear formation closed at both ends is fixed by vertically disposed screw rod in the two ends of pressing plate, multiple bundle cable is placed in layer structure side by side successively, but in use, pressing plate is on fibre core beam tube all the time, fibre core beam tube stress deformation then in layer structure can cause loss excessive, the fibre core beam tube being particularly positioned at lowermost layer is stressed the most serious, make that the optical fiber in fibre core beam tube is long-term stressedly to rupture, affect normal indoor communications.
Summary of the invention
The object of the present invention is to provide a kind of house wiring cable clamp, while facilitating optical cable to fix fast, reduce the stressed loss of optical cable, improve stability during optical cable work.
Object of the present invention is achieved through the following technical solutions:
A kind of house wiring cable clamp, comprise base plate and multiple stacked up and down and be the pressing plate of rectangle, center-pole is fixed with in the middle part of described base plate, multiple described pressing plate is rotated by the through hole of its one end end opens and is arranged on center-pole, the other end sidewall of described pressing plate has U-type groove, and be provided with in described U-type groove inwall both sides opposed and be the elastic protrusion of arc, base plate is also fixed with the supporting rod corresponding with U-type groove, when optical cable is fixed, describedly to be configured to the position of pressing plate, described press plate rotary is to contacting with supporting rod, and supporting rod sidewall produces extruding until supporting rod enters in U-type groove completely to two elastic protrusions.When the present invention uses, single pressing plate is set on center-pole successively, be about to the gap location between the optical harness centering bar put in order side by side and supporting rod, then pressing plate is set on center-pole, rotary pressure plate makes it rotate until contact with supporting rod around center-pole, now U-type groove is just to supporting rod, and due to the diameter of the gap ratio supporting rod between two elastic protrusion arc tops smaller, make the outer wall of supporting rod produce extruding to the elastic protrusion of two arcs to make it deformation occurs, until supporting rod enters after in U-type groove completely, elastic protrusion is replied deformation and again carries out semiclosed restriction to the openend of U-type groove, and then achieve fixing supporting rod, optical harness is then fixed in the coffin between pressing plate and base plate, by parity of reasoning, the optical harness that many groups are put in order is fixed successively, finally it is reinforced by securing members such as nuts at center-pole and supporting rod upper end, final realization is fixed installation to multiple optical harness be arranged side by side.
And two elastic protrusions remain certain acting force to supporting rod outer wall, namely each pressing plate be in the region, middle and lower part of layer structure is made can to bear part gravity, this gravity be layer structure upper zone in the gravity sum of optical harness and pressing plate, and then reduce the bearing capacity of the optical harness outer wall near base plate side, avoid the optical harness in this region stressedly to rupture because of long-term, affect normal indoor communications; Wherein when changing cable runs configuration, only the securing member of center-pole and supporting rod upper end need be removed, simultaneously by pressing plate reverse rotation, being separated between pressing plate with multiple stacked optical harness can be realized, avoid the flow process of taking out pressing plate when lightguide cable link is changed one by one from two screw rods, be reduced in the possibility that in pressing plate taking-up process, optical cable is impaired.
Be fixed with the column, the limiting plate that are parallel to each other respectively at described base plate two ends, and just to described supporting rod in the middle part of described column, described limiting plate is just to described center-pole.The U-shaped region of a hollow is formed between the column be arranged in parallel and limiting plate, this U-shaped region can produce guiding and position-limiting action to multiple optical harness stacked up and down, avoid optical cable directly and between center-pole and supporting rod, hard contact occur and make the optical fiber of optical cable inside impaired, reduce the probability of optical cable external insulation wearing and tearing simultaneously.
The cross section of described supporting rod is oval, and the straight line at the major axis place of described ellipse is parallel with the minor face of described pressing plate.As preferably, the cross section of supporting rod is set to ellipse, and supporting rod is when the contact with two elastic protrusions, there is twice deformation in elastic protrusion, i.e. compression set and reply deformation, and remain at reply deformation process latter two elastic protrusion certain acting force is produced to supporting rod outer wall, and then there is downward displacement after avoiding its top of pressing plate stressed.
The present invention compared with prior art, has following advantage and beneficial effect:
1, the present invention is when changing cable runs configuration, only the securing member of center-pole and supporting rod upper end need be removed, simultaneously by pressing plate reverse rotation, being separated between pressing plate with multiple stacked optical harness can be realized, avoid the flow process of taking out pressing plate when lightguide cable link is changed one by one from two screw rods, be reduced in the possibility that in pressing plate taking-up process, optical cable is impaired;
2, the U-shaped region of a hollow is formed between the column be arranged in parallel in the present invention and limiting plate, this U-shaped region can produce guiding and position-limiting action to multiple optical harness stacked up and down, avoid optical cable directly and between center-pole and supporting rod, hard contact occur and make the optical fiber of optical cable inside impaired, reduce the probability of optical cable external insulation wearing and tearing simultaneously;
3, supporting rod of the present invention is when the contact with two elastic protrusions, there is twice deformation in elastic protrusion, i.e. compression set and reply deformation, and remain at reply deformation process latter two elastic protrusion certain acting force is produced to supporting rod outer wall, and then there is downward displacement after avoiding its top of pressing plate stressed.
