Abstract
The utility model discloses a combined plastic cable testing bridge, consisting of an upper cover board and a groove body with side walls, wherein, the upper cover board covers the two sides of the groove body. The utility model is characterized in that the tops of the two side walls of the groove body are provided with U-shaped fastening grooves, the sides of the upper parts of which are inclined planes; the lower parts of the two sides of the upper cover board are provided with corresponding fastening hooks which contact the sections of the upper parts of the U-shaped fastening grooves. The groove body is made into a whole with two side walls through plastic extruding, which avoids consolidation and saves labor; the adopted fastening bard structure has forced fit, firm connection, and is uneasy to slip off.
Description
Technical field
The utility model relates to cable testing bridge, particularly relates to the combined plastic cable testing bridge, belongs to the electric wire laying apparatu, is particularly useful for overall cable installations such as basement.
Background technique
Electric wire is indoor laying in factories and miness, enterprise and building, be extensive use of cable testing bridge, existing cable testing bridge, it is made mostly to be metallic material greatly, for example steel crane span structure, stainless steel crane span structure, aluminum alloy crane span structure, glass fiber reinforced plastic bridge etc., the shortcoming that above-mentioned all kinds of cable testing bridge exists is the manufacturing process complexity, cost height, and some easy corrosion, poor insulativity, weight is heavy, is unfavorable for installation and maintenance.So Plastic cable bridge occurred, disclose a kind of mutual friction tight linkage structure of twin bead mounting groove of utilizing the suitable for reading and cover plate of frid as ZL 200420026759.9, this portal structure is simple, and is easy for installation, but it is relatively poor to connect fastness, mandatory cooperation dynamics deficiency; Frid and groove lid form entity lath, high material consumption through extrusion molding.Other has the disclosed frid of patent No. ZL200520200533.0 is assembled by left sideboard, right sideboard and base plate, more firm though this kind structure has mandatory annexation, makes, installs cumbersome.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming that prior art exists, to provide a kind of easy for installation, and it is firm to connect, corrosion resistant, the combined plastic cable testing bridge of material province.
The technological scheme of the utility model combined plastic cable testing bridge is: be made up of upper cover plate and the cell body that is shaped on sidewall, upper cover plate is buckled on the both sides of cell body, the top that it is characterized in that the cell body two side is shaped on U type snap groove, the upper side of U type snap groove is the inclined-plane, be shaped on corresponding snapping hook under the both sides of upper cover plate, the snapping hook contacts with U type snap groove top section.
Combined plastic cable testing bridge of the present utility model, cell body is made the one of two side through extrusion molding, need not assembly unit, the artificial province; Because being shaped on the upper side of U type snap groove at the top of two side is the inclined-plane, and the upper cover plate both sides are shaped on the snapping hook downwards, thus U type snap groove cooperate with the snapping hook have easy for installation, mechanical strength is good, adopts the snapping overhead structure, mandatory cooperation, it is firm to connect, and is difficult for slippage.
Combined plastic cable testing bridge of the present utility model, the upper side and the snapping hook fitting surface of its described U type snap groove are gapped, are easier to install.Its described cell body middle part is shaped on cavity, saves material, reduces cost, and is shaped on stiffening rib in the cavity, helps improving overall mechanical strength.Be shaped on attachment hole in the sidewall of its cell body, can carry out length to cell body during use and connect.The bottom of its cell body is provided with positioning bar, and cell body top and positioning bar corresponding section are provided with tenon, and link can insert the locating slot between positioning bar and sidewall and tenon and the sidewall, thereby connects the cell body of different direction.
Description of drawings
Fig. 1 is the structural representation of combined plastic cable testing bridge;
Fig. 2 is the partial enlarged drawing of Fig. 1;
Fig. 3 is the sidewall schematic representation of cell body.
Embodiment
The utility model discloses a kind of combined plastic cable testing bridge, as shown in Figure 1 and Figure 2, be made up of upper cover plate 1 and the cell body 2 that is shaped on sidewall, cell body 2 is one-body molded, need not assembly unit, the artificial province; Upper cover plate 1 and cell body 2 all are plastic article, and be not perishable, and insulation effect is good, and is economical and practical; Upper cover plate 1 is buckled on the both sides of cell body 2, its major technology is characterised in that the top of cell body 2 two sides 25,26 is shaped on U type snap groove 21, the upper side of U type snap groove is inclined-plane 22, be shaped on corresponding snapping hook 11 under the both sides of upper cover plate 1, snapping hook 11 contacts with U type snap groove top section 23.U type snap groove 21 cooperates with snapping hook 11 and has easy for installationly, and mechanical strength is good, adopts the snapping overhead structure, mandatory cooperation, and it is firm to connect, and is difficult for slippage.The upper side 22 of its described U type snap groove 21 is gapped with snapping hook fitting surface 12, is easier to install.Its described cell body 2 middle parts are shaped on cavity, save material, reduce cost, and are shaped on stiffening rib 24 in the cavity, help improving overall mechanical strength.Be shaped on attachment hole 27 in the sidewall 25,26 of its cell body, as shown in Figure 3, thereby available connecting sheet is connected to a fixed two cell bodies and obtains required length.The bottom of its cell body 2 is provided with positioning bar 28, and cell body 2 tops and positioning bar 28 corresponding sections are provided with tenon 29, and link can insert the locating slot between positioning bar 28 and sidewall 25,26 and tenon 29 and the sidewall 25,26, thereby connects the cell body 2 of different direction.In actual applications,, can buckle upper cover plate, constitute the slot type cable testing bridge if be used for laying computer cable, telecommunication cable, thermocouple cable etc. to the shielding interference of actuating cable and the higher occasion of requirement of shelter of heavy corrosion environment cable; Require the occasion that load is big, radiate heat and ventilate is good if be used for oil, chemical industry etc., can use cell body separately, constitute the pellet type cable testing bridge.
