Abstract

A steel cable bridging locker for fast connection of the groove and groove cover of the steel cable bridging frame, wherein, the stand side of the groove cover is pressed with a concave shoulder, and the corresponding part of the groove is struck out a long hole; the shoulder is locked into the hole after the locker is locked, thereby having retreat function and realizing the goal of locking.

Description

Steel cable testing bridge locker

Affiliated technical field

The utility model relates to the locker of a kind of steel cable testing bridge cell body and groove lid, and especially fastening structure is simple, and saving of work and time is raised the efficiency, and fastens firmly.

The steel cable testing bridge is the grooved container that forms with the sheet metal bending, is made up of cell body and groove lid, and inside is used to place electric wire, plays the protection to electric wire, protective action.

Background technique

At present, the Placement that adopts tapping screw that is connected of the cell body of known steel cable testing bridge and groove lid was both bored 4 holes respectively in the top edges of cell body and groove lid; with tapping screw the groove lid is fixed on the cell body again; make crane span structure become the container of sealing, play to electric wire the protective action of cable.But, adopt the Placement of screw to have following shortcoming, at first the tip of tapping screw is positioned at cell body, if screw is long or there are vibrations in electric wire, damage might be caused to the isolation layer of electric wire in the tip of screw so, brings potential safety hazard, and the boring of pontic bridge lid is time-consuming in secondly producing, it is time-consuming to install and keep in repair the some screws of palpus loading and unloading, and efficient is low.

Summary of the invention

Use the screw connection easily to cause potential safety hazard and the loaded down with trivial details deficiency of installation in order to overcome existing crane span structure, the utility model provides the locker of a kind of steel cable testing bridge cell body and groove lid, effectively eliminated unsafe factor, fastening structure is simply firm simultaneously, cost is low, installs and the repair demolition saving of work and time.

The technical scheme in the invention for solving the technical problem is: at the inwardly protruded sawtooth pattern half the circumference of the sleeve where it joins the shoulder of two vertical side difference one section rectangle of punching press of crane span structure lid, the top of rectangle half the circumference of the sleeve where it joins the shoulder is dissengaged positions and inwardly compresses into, all the other 3 limits connect and compress into for sawtooth pattern, at the relevant position of cell body punching out one rectangular opening, external force makes cell body two stiles overcome elasticity to internal strain when the groove lid fastens with cell body, when the groove lid is anchored to the position, the half the circumference of the sleeve where it joins the shoulder of its groove lid falls into the rectangular opening of cell body, two stiles of cell body are because elastic reaction, the reinstatement attitude, the half the circumference of the sleeve where it joins the shoulder of groove lid and the coincident in cell body hole play the retaining effect, reach the snap close purpose.When needs were opened the groove lid, the cell body stile is inwardly pushed away a slit can be opened.

The beneficial effects of the utility model are, both can cover snap close fast to cell body and groove by the simple processing to crane span structure, have eliminated unsafe factor simultaneously, and are simple in structure.

Description of drawings

Further specify this use is novel below in conjunction with drawings and Examples.

Fig. 1 is the sawtooth pattern half the circumference of the sleeve where it joins the shoulder of the utility model groove lid punching press.

Fig. 2 is a cell body punching out rectangular opening.

Fig. 3 is the retaining schematic diagram after cell body and groove lid fasten.

Embodiment

Among Fig. 1, groove lid (1), the inwardly protruded sawtooth pattern half the circumference of the sleeve where it joins the shoulder of punch process (2), among Fig. 2, cell body (3), rectangle punching (4),

Among Fig. 4, the half the circumference of the sleeve where it joins the shoulder (2) of groove lid falls into the rectangular opening (4) of cell body, reaches the effect of locking retaining.

Claims

1, the locker of a kind of steel cable testing bridge cell body and groove lid is characterized in that two stile punching presses, the one inwardly protruded sawtooth pattern half the circumference of the sleeve where it joins the shoulder at the groove lid, is covering corresponding cell body stile upper punch one rectangular opening with groove.

2, locker according to claim 1 is characterized in that: the height of the rectangular opening of its cell body and length are slightly larger than the height and length of groove lid half the circumference of the sleeve where it joins the shoulder, and half the circumference of the sleeve where it joins the shoulder falls into the hole when making fastening, and the edge of half the circumference of the sleeve where it joins the shoulder becomes same plane with bore edges, play the retaining effect.
