this embodiment provides a special security fence is detected to engineering, as shown in fig. 1 and fig. 2, including first crossbeam 1, second crossbeam 2, bracing piece 3, telescopic link 4, horizontal pole 5 and connecting seat 6, the front of first crossbeam 1 and second crossbeam 2 all is equipped with the reflection of light subsides, can remind passing pedestrian and vehicle to notice at night like this and dodge, improves the security that detects the operation. The connecting base 6 comprises a connecting screw rod 61 and a platform plate 62, and one end of the connecting screw rod 61 is fixedly connected with the center of the end face of the platform plate 62; as shown in fig. 3, the first beam 1 includes a first hinge bar 11, a bottom plate 12 and two side plates 13 parallel to each other, the first hinge bar 11 is disposed between the two side plates 13 and fixedly connected to the side plates 13, the first hinge bar 11 is perpendicular to the side plates 13, the bottom plate 12 is disposed between the two first hinge bars 11 and fixedly connected to the side plates 13, the bottom plate 12 is shorter than the side plates 13, and an abdicating hole is formed from the end of the bottom plate 12 to the end of the side plates 13. The stiff end of bracing piece 3 is articulated with first articulated thick stick 11, the one end and the bottom plate 12 fixed connection of telescopic link 4, the other end and the 2 fixed connection of second crossbeam of telescopic link 4, many telescopic links 4 are arranged along the length direction of first crossbeam 1, the length direction of telescopic link 4 is perpendicular with 1 length direction of first crossbeam, the length direction of first articulated thick stick 11 is perpendicular with 4 length direction of telescopic link.

The tip of second crossbeam 2 is equipped with the spacing groove 21 that is used for placing bracing piece 3 free end, and the middle part of second crossbeam 2 is equipped with storage tank 22, and the opening direction of this storage tank 22 is towards the inside, is equipped with the articulated thick stick 23 of second parallel with telescopic link 4 in the storage tank 22, and the stiff end of horizontal pole 5 is articulated with the articulated thick stick 23 of second, and the free end of horizontal pole 5 is equipped with the screw hole 51 with connecting screw 61 matched with.

One end of the limiting groove 21, which is far away from the accommodating groove 22, is provided with a limiting mechanism 24, the limiting mechanism 24 is an elastic metal sheet, and the metal sheet is fixedly connected with the second beam 2. After the rail is unfolded, the free end of the supporting rod 3 is located in the limiting groove 21, the limiting mechanism 24 is arranged to prevent the supporting rod 3 from rotating around the first hinge rod at will, and the stability of the unfolded rail is improved.

Specifically, as shown in fig. 4, the bottom plate 12 is connected to the lower portion of the side plate 13, so that the upper surface of the bottom plate 12 and the inner surfaces of the two side plates 13 together define a groove, when the enclosure is retracted, the supporting rod 3 rotates upward around the first hinge bar 11 and can be completely accommodated in the groove, and at this time, one side of the supporting rod 3 close to the side plate 13 abuts against the side plate 13, so that the supporting rod 3 cannot rotate randomly, and transportation is facilitated.

In this embodiment, as shown in fig. 5 and 7, two second hinge bars 23 and two cross bars 5 are provided, the second hinge bars 23 are symmetrically disposed at two ends of the accommodating groove 22, the length of the cross bar 5 is greater than half of the length of the accommodating groove 22, a fixed end of one cross bar 5 is hinged to one of the second hinge bars 23, and a fixed end of the other cross bar 5 is hinged to the other second hinge bar 23. When the free ends of the two cross rods 5 are stacked, the central axes of the threaded holes 51 in the two cross rods 5 are overlapped, and then the connecting screw 61 of the connecting seat 6 penetrates through the two threaded holes 51 to realize connection, so that the two cross rods 5 and the second cross beam 2 form a triangle (as shown in fig. 6), the cross rods 5 cannot be randomly translated when being subjected to transverse thrust, and the reliability of the fence is improved. Article such as the instrument of placing on connecting seat 6 are simultaneously as the balancing weight of rail, simply place with traditional rail and compare, have better stability, when check out test set is few and the rail is many, can carry arbitrary heavy objects such as brick or stone temporarily in the detection place and regard as the balancing weight, equipment strong adaptability.

When the fence is unfolded, the cross bars 5 are firstly rotated out of the accommodating grooves 22, then the connecting screw rods 61 are simultaneously inserted into the threaded holes 51 on the two cross bars 5, and then the telescopic rods are stretched to enable the supporting rods 3 to rotate around the first hinged rods 11 until the free ends of the supporting rods 3 bypass the limiting mechanisms 24 and are clamped into the limiting grooves 21.

If any object counter weight is not placed on the connecting seat 6, the connecting seat 6 can be rotated, so that the bottom of the connecting screw rod 61 is slightly higher than the plane of the bottom of the second cross beam 2 when the cross rod 5 is parallel to the ground, and therefore when the connecting screw rod 61 is in contact with the ground, the supporting rod 3 can slightly incline towards one side of the connecting seat 6, and the fence is stable and firm. If equipment or a balancing weight needs to be placed, the connecting seat 6 needs to be rotated, so that the bottom of the connecting screw 61 and the bottom surface of the second cross beam 2 are in the same plane, and the platform plate 62 is in a horizontal state.
