Abstract
Provided is a plug type fixing method of a cable bridge groove body and a cover board. Overlap positions of the side faces of the cable bridge groove body and the cover are respectively provided with a long square hole in a stamping mode, two long square holes of the cover board, covered on the groove body, are overlapped, plastic plugs are plugged into the long square holes according to the plane direction and then are twisted 90 degrees, and the cable bridge groove body and the cover board are fixed. When the cover board needs opening, the plastic plugs are twisted 90 degrees again, and the plastic plugs are taken out.
Description
Technical field
The utility model relates to a kind of embolism formula fixation method with cable testing bridge cell body and cover plate.
Background technique
Present its cell body of known cable testing bridge mostly uses self threading pin to be connected with the fixation method of cover plate.
Cable testing bridge is comprised of cell body and the cover plate that the sheet metal bending forms, and usually every long 2 meters can connect unlimited prolongation, and cable laying covers cover plate on cell body and fixing in cable testing bridge, and cable testing bridge plays a protective role to inside cable.Usually the cable testing bridge cell body mostly adopts self threading pin to be connected with the fixation method of cover plate, at the bottom of major advantage is simple in structure, cost.But shortcoming is cover plate to be installed to tighten the labor intensity of self threading pin large, wastes time and energy, and in addition because to use self threading pin to fix its nail tip inner at cable testing bridge, has the security hidden trouble of damage cable insulation.
Summary of the invention
Use the fixing deficiency that exists of self threading pin in order to overcome existing cable crane span structure cell body and cover plate, the utility model provides the embolism formula fixation method of a kind of cable testing bridge cell body and cover plate, fixedly cell body and cover plate structure are simple with the method, do not need instrument, time saving and energy saving, without sharp object, reliable to cable security in its cable testing bridge.
The technical scheme in the invention for solving the technical problem is: rush respectively an oblong aperture at the cell body of cable testing bridge and the overlapping position of cover plate side, cover plate covers two holes coincidence on cell body, the plastics embolism filled in to turn round after the oblong aperture according to in-plane again turn 90 degrees, both cell body and the cover plate of cable testing bridge can be fixed.Every cable testing bridge is at two ends and both sides totally four immovable points.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is that cell body and the cover plate that the plastics embolism is filled in direction and cable testing bridge rushes oblong aperture position principle plan view.
Fig. 2 is the side view of Fig. 1.。
Fig. 3 is the principle plan view after the plastics embolism is filled in oblong aperture.
Fig. 4 is the side view of Fig. 3.
Fig. 5 turns round the plastics embolism to turn 90 degrees, the principle plan view that the cell body of cable testing bridge and cover plate is fixing.
Fig. 6 is the side view of Fig. 5.
Fig. 7 is plastics embolism part plan view.
Fig. 8 is the side view of Fig. 7.
Fig. 9 is the plan view of Fig. 7.
Among Fig. 1, Fig. 21, plastics embolism, the 2. cell body of cable testing bridge and the cover plate oblong aperture of rushing, 3. cover plate, 4. cell body.
Embodiment
The side of the cell body of cable testing bridge (4) and cover plate (3) overlaps the same position place and rushes respectively an oblong aperture (2) in Fig. 1, Fig. 2, make cover plate (3) cover that two oblong aperture overlap when cell body (4) is upper, the cell body of the in-plane of plastics embolism (1) and cable testing bridge and cover plate oblong aperture (2) are aligned fill in.
In Fig. 3, Fig. 4, the plastics embolism (1) of filling in turned round and turn 90 degrees.
The embolism (1) of turning round in Fig. 5, Fig. 6 after turning 90 degrees is fixed cell body and the cover plate of cable testing bridge.
Fig. 7, Fig. 8, the middle part of plastics embolism is circular among Fig. 9, in oblong aperture, rotate arbitrarily, a direction of end is flat, be convenient to fill in the cable testing bridge oblong aperture, another direction is given prominence to, be convenient to block oblong aperture, both direction is 90 degree each other, when the plastics embolism fill in the oblong aperture and turn round turn 90 degrees after, the projection of plastics embolism end blocks oblong aperture, and the plastics embolism can outwards not deviate from, when needs are opened the cover plate of cable testing bridge, the plastics embolism turned round again turn 90 degrees, make the plane of plastics embolism end align oblong aperture and just the plastics embolism can be taken out and open cover plate.
Claims (3)
1. the embolism formula fixation method of a cable testing bridge cell body and cover plate, it is characterized in that: rush respectively an oblong aperture at the cell body of cable testing bridge and the overlapping position of cover plate side, cover plate covers two oblong aperture coincidence on cell body, the plastics embolism filled in to turn round after the oblong aperture by in-plane again turn 90 degrees, cell body and the cover plate of cable testing bridge are fixed.
2. the embolism formula fixation method of cable testing bridge cell body according to claim 1 and cover plate is characterized in that: for circular, can rotate arbitrarily in oblong aperture in the middle part of the plastics embolism, a direction of end is flat, be convenient to fill in oblong aperture, other direction is given prominence to, and is convenient to block oblong aperture.
3. the embolism formula fixation method of cable testing bridge cell body according to claim 1 and cover plate is characterized in that: every cable testing bridge is at two ends and both sides totally four immovable points.
