Description

Technical Field

[0001] The present application relates to the field of power protection, and in particular to a power construction isolation and insulation safety fence. Background Art

[0002] At present, when carrying out power construction, people often approach or enter the construction site, causing a series of safety hazards. Therefore, for safety reasons, guardrails must be erected at the construction site to surround the power facilities under construction, so as to warn people to stay away and remind people not to get close.

[0003] Regarding the above-mentioned related technologies, there are still some defects: However, the commonly used safety guardrails are mainly integrated steel guardrails. After the power construction is completed, since the safety guardrail is an integrated setting, the entire guardrail needs to be moved during transportation, which occupies a large space and is very inconvenient during transportation. Utility Model Content

[0004] In order to facilitate transportation and reduce storage space, the present application provides an isolation and insulating safety fence for power construction.

[0005] The present application provides an electric power construction isolation insulation safety fence, which adopts the following technical solutions:

[0006] An insulating safety fence for electric power construction includes a column and a fence unit, wherein the fence unit is detachably connected to the column, and the fence unit is composed of a cross bar and a baffle bar. The column is provided with a connecting hole for inserting the cross bar, and a locking piece is slidably connected in the column, and the locking piece locks the cross bar inserted in the column; the cross bar is also provided with a sliding cavity, and a movable row of plates is slidably connected in the sliding cavity, and a plurality of rectangular blocks are slidably connected in the movable row of plates.

[0007] By adopting the above technical solution, a sustainable connection between the column and the fence unit can be achieved by sliding the locking piece located in the column up and down, and between adjacent fence units, it is only necessary to slide the movable row plate onto the two cross bars at the same time, and the two cross bars can be relatively fixedly connected by snapping together with the rectangular block.

[0008] Optionally, a parallel plate is integrally formed at one end of the fence units that are close to each other, a hinge is inserted into the parallel plate, both ends of the hinge can be inserted into adjacent parallel plates respectively, and a shielding plate that can shield the hinge is slidably connected to the parallel plate.

[0009] By adopting the above technical solution, when connecting the fence units, the hinge can be inserted into the parallel plate to make a preliminary connection between the two fence units, and the two fence units can also be connected to each other in rotation through the action of the hinge and the parallel plate.

[0010] Optionally, the parallel plate can be magnetically connected to the hinge.

[0011] By adopting the above technical solution, when the hinge is not in use, the hinge can be temporarily brought into contact with the outer plate surface of the parallel plate, and the hinge can be temporarily stored through magnetic connection.

[0012] Optionally, one end of the rectangular block away from the cross bar is rotatably connected to a threaded disc, and the movable plate is provided with a threaded hole threadably connected to the threaded disc.

[0013] By adopting the above technical solution, the threaded disc is fixed to the movable row plate, so that the rectangular block is not easy to fall out of the cross bar.

[0014] Optionally, the locking member includes a displacement rod and a locking hook formed integrally with the displacement rod, and a recessed groove for the locking hook to be inserted into is provided on the cross bar; a reset spring is also connected between the displacement rod and the column.

[0015] By adopting the above technical solution, the locking hook is inserted into the recessed groove, and due to the action of the return spring, the stability of the locking hook in the recessed groove is enhanced.

[0016] Optionally, the end of the cross bar is also provided with an inclined surface, and the inclined surface can be in close contact with the hook surface of the locking hook.

[0017] By adopting the above technical solution, the inclined surface contacts the locking hook first, causing the displacement rod to move, making it easier for the subsequent locking hook to be inserted into the cross bar.

[0018] Optionally, one end of the displacement rod away from the return spring is also rotatably connected to a limit rod, and when the limit rods are parallel to each other, the locking hook is misaligned with the cross bar; when the limit rods are in the same straight line, the locking hook is inserted into the recessed groove.

[0019] By adopting the above technical solution, when the user needs to separate the column from the fence unit, the limit rod can be rotated to make the limit rods parallel to each other, and the limit rod abuts against the displacement rod. At this time, the locking hook is always misaligned with the cross bar, which makes it easy to move the cross bar out of the sliding groove.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] The fence unit and the column are locked by simply pulling the displacement rod, and the two fence units are connected by combining and splicing the movable panels, which is simple and convenient to operate;

[0022] When two fence units are connected, the hinged member can be used to achieve initial fixation of the two fence units, and the hinged member can be used to achieve hinged connection or quick separation of the two fence units. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-7 This application is described in further detail.

[0032] The present application embodiment discloses an electric power construction isolation insulation safety fence. Figure 1 , Figure 2A power construction isolation insulation safety fence includes a column 1 and a fence unit 2. There are two columns 1, and the fence unit 2 is connected between the two columns 1. The columns 1 and the fence, and the fences are all detachably connected. When the fence unit 2 and the column 1 are both separate individuals, it is convenient for users to carry or store them.

[0033] Reference Figure 2 , Figure 3 The fence unit 2 is composed of a crossbar 3 and a stop bar 4. A plurality of crossbars 3 are arranged in a linear array between two crossbars 3 and are formed integrally with the crossbars 3. A connecting hole 5 for inserting the end of the crossbar 3 is provided on the side of the column 1 facing the fence unit 2; a through hole 17 connected to the connecting hole 5 is also provided along the length direction of the column 1. A locking member 21 is slidably connected in the through hole 17. After the crossbar 3 is inserted into the connecting hole 5, the locking member 21 can lock the crossbar 3 in the column 1, thereby realizing a relatively fixed connection between the fence unit 2 and the column 1.

[0034] Reference Figure 2 , Figure 3 The locking member 21 includes a displacement rod 20 and a locking hook 6 formed integrally with the displacement rod 20. The displacement rod 20 is a straight rod and extends along the opening direction of the through hole 17. The number of the locking hooks 6 is the same as the number of the through holes 17. When the cross bar 3 is inserted into the connecting hole 5, an inclined surface 15 is also provided at the end of the cross bar 3. The inclined surface 15 will first contact the locking hook 6, and as the cross bar 3 continues to go deeper into the connecting hole 5, the locking hook 6 will move toward the opening direction of the through hole 17 under the push of the inclined surface 15 until the locking hook 6 is inserted into the concave groove 13 provided on the cross bar 3.

[0035] A return spring 14 is connected to one end of the displacement rod 20 away from the opening of the through hole 17. When the displacement rod 20 moves toward the opening of the through hole 17, the return spring 14 will be stretched and make the displacement rod 20 have a tendency to move in the direction where the return spring 14 exists.

[0036] The end of the displacement rod 20 away from the reset spring 14 is also rotatably connected to the limit rod 16. The limit rod 16 always remains outside the opening of the through hole 17. And according to the different rotation positions of the limit rod 16, the limit rod 16 has a locking position and a reset position. When the two limit rods 16 are parallel to each other, the limit rod 16 is in the reset position. At this time, one end of the limit rod 16 will abut against the column 1, and the displacement rod 20 will move toward the opening of the through hole 17 due to the action of the limit rod 16. At the same time, the reset spring 14 is in a stretched state, and the cross bar 3 can freely enter and exit the connecting hole 5; when the two limit rods 16 are on the same straight line, the limit rod 16 is in the locking position, and the rod body of the limit rod 16 will be tightly attached to the column 1, and the displacement rod 20 will move in the direction where the reset spring 14 exists under the drive of the reset spring 14, so that the locking hook 6 is inserted into the recessed groove 13 to limit the cross bar 3.

[0037] Reference Figure 4 , Figure 5 A sliding cavity 7 is also provided on the crossbar 3, and the opening direction of the sliding cavity 7 is provided along the length direction of the crossbar 3. A movable plate 8 is slidably connected in the sliding cavity 7, and the movable plate 8 cannot be deformed and can slide freely on two adjacent crossbars 3. A plurality of rectangular blocks 9 are also provided on the movable plate 8, and the rectangular blocks 9 can slide on the movable plate 8 in the vertical direction and be inserted into the crossbar 3.

[0038] When the user needs to splice adjacent fence units 2, he only needs to align the two cross bars 3 so that the movable plate 8 can slide freely on the two cross bars 3. After that, the user moves the movable plate 8 to the two cross bars 3, and moves the plurality of rectangular blocks 9 to different cross bars 3, and inserts the rectangular blocks 9 into the rectangular grooves 18 opened in the cross bars 3, so as to relatively and fixedly connect the two fence units 2.

[0039] The end of the rectangular block 9 is also rotatably connected with a threaded disc 12. The movable plate 8 is provided with a threaded hole that can be threadedly connected with the threaded disc 12. After the rectangular block 9 is inserted into the rectangular groove 18, the user rotates the threaded disc 12 to fix the rectangular block 9 in the rectangular groove 18 through the threaded disc 12.

[0040] Reference Figure 6 , Figure 7, a parallel plate 10 is integrally formed at one end of the fence unit 2 that is close to each other, and a hinge 19 is inserted into the parallel plate 10, and the hinge 19 includes a rotation axis and two rotation plates rotatably connected to the rotation axis. The two rotation plates can be inserted into the parallel plate 10 respectively, and the rotation axis is located between the two cross bars 3. When the user wants to connect the fence unit 2 through the rectangular block 9 and the threaded disc 12, the two fence units 2 can be preliminarily fixed by the cooperation of the hinge 19 and the parallel plate 10. After the user inserts the hinge 19 into the parallel plate 10, if the moving plate 8 has not yet contacted the two cross bars 3 at the same time, the two fence units 2 at this time can rotate with the rotation axis as the reference line. If the moving plate 8 contacts the cross bars 3 at the same time, the two cross bars 3 can be prevented from rotating and can only be kept in a straight line by limiting the moving plate 8.

[0041] A shielding plate 11 capable of shielding the hinge 19 is also slidably connected to the parallel plate 10. After the hinge 19 is inserted into the parallel plate 10, the shielding plate 11 can be pushed to make the shielding plate 11 contact with the hinge 19, reducing the possibility of the hinge 19 coming off the parallel plate 10.

[0042] When the user wants to separate the two fence units 2, the hinge 19 needs to be taken out from the parallel plate 10. The hinge 19 after being taken out can be tightly attached to the outer wall of the parallel plate 10. The parallel plate 10 can be magnetically connected to the hinge 19 to temporarily store the hinge 19 to prevent the hinge 19 from being lost.

[0043] The embodiment of the present application discloses an implementation principle of an isolation and insulating safety fence for power construction: when assembling the column 1 and the fence unit 2, and the fence unit 2 and the fence unit 2, the user can first insert the cross bar 3 into the connecting hole 5 of the column 1, and lock the connecting hole 5 through the locking piece 21, so as to achieve a fixed connection between the column 1 and the fence unit 2; and when it is necessary to achieve a fixed connection between the fence unit 2 and the fence unit 2, it is necessary to first use the hinge 19 to insert the parallel plate 10, and preliminarily fix the fence unit 2 and the fence unit 2, so that the fence unit 2 and the fence unit 2 can be hinged, and then move the movable plate 8 to the two cross bars 3, and insert the rectangular block 9 into the rectangular groove 18 to achieve a relative fixed connection between the two cross bars 3.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
