Description
Technical Field
The utility model relates to a safe cat ladder technical field, especially a safe cat ladder net piece inner supporting structure.
Background
In the building construction process, often can use safe cat ladder, safe cat ladder's construction must be first, and the periphery will be enclosed with the net piece of rectangle. The existing net sheet is basically a rectangular frame formed by a plurality of section steels, two section steels are crossed in the frame to form an X shape, the X shape plays a role of internal support, and finally a filter screen is covered on the X shape. In the use, especially when the cat ladder is higher, the net piece atress that leans on the bottom more just is big more, and upper and lower frame appears the deformation very easily, but current interior support is generally by two shaped steel welding or fix with screw on the frame, and if upper and lower frame appears when sunken, interior support does not play the effect of support. In addition, the inner support cannot be detached, and the carrying is inconvenient.
SUMMERY OF THE UTILITY MODEL
To the above situation, for overcoming prior art's defect, the utility model provides a safe cat ladder supports structure in net piece, the effectual current net piece of having solved is supported and can not play due effect to the last lower frame of net piece, and whole net piece can not be dismantled, the problem of inconvenient transport.
The technical scheme for solving the problem is that the telescopic rod type U-shaped plate comprises a first U-shaped plate which is horizontally placed and has a downward opening, a second U-shaped plate which is parallel to the first U-shaped plate is arranged above the first U-shaped plate, the second U-shaped plate has an upward opening, two bilaterally symmetrical telescopic rods are arranged between the first U-shaped plate and the second U-shaped plate, and the two telescopic rods are splayed; the telescopic rod comprises a cylinder, the upper end of the cylinder is hinged with the second U-shaped plate, a sliding rod is inserted in the cylinder and can be fixed in the cylinder, the lower end of the sliding rod extends out of the cylinder, a swing rod is arranged below the sliding rod, and the lower end of the swing rod is hinged with the first U-shaped plate; stud bolts are arranged between the sliding rod and the swing rod, threaded holes are formed in the lower end of the sliding rod and the upper end of the swing rod, and the sliding rod and the swing rod are connected together through the stud bolts.
The utility model discloses the structure is ingenious, can fully play the supporting role to the last lower frame of net piece, and convenient the dismantlement is easily changed, convenient transport.

Detailed Description
The following detailed description of embodiments of the present invention is made with reference to the accompanying drawings.
As shown in fig. 1 to 4, the utility model comprises a first U-shaped plate 1 placed horizontally and having a downward opening, a second U-shaped plate 2 parallel to the first U-shaped plate 1 is arranged above the first U-shaped plate 1, the second U-shaped plate 2 has an upward opening, two bilaterally symmetrical telescopic rods are arranged between the first U-shaped plate 1 and the second U-shaped plate 2, and the two telescopic rods are in a shape of a Chinese character 'ba'; the telescopic rod comprises a cylinder 3, the upper end of the cylinder 3 is hinged with the second U-shaped plate 2, a sliding rod 4 is inserted in the cylinder 3, the sliding rod 4 can be fixed in the cylinder 3, the lower end of the sliding rod 4 extends out of the cylinder 3, a swing rod 5 is arranged below the sliding rod 4, and the lower end of the swing rod 5 is hinged with the first U-shaped plate 1; a stud bolt 6 is arranged between the sliding rod 4 and the swing rod 5, threaded holes are formed in the lower end of the sliding rod 4 and the upper end of the swing rod 5, and the sliding rod 4 and the swing rod 5 are connected together through the stud bolt 6.
In order to fix the sliding rod 4 in the cylinder 3, a plurality of clamping holes are formed in the cylinder 3, positioning holes are formed in the sliding rod 4, and the sliding rod 4 and the cylinder 3 are fixed together when pins penetrate through the clamping holes and the positioning holes.
It is noted that, in use, it is important to maintain the first U-shaped plate 1 parallel to the second U-shaped plate 2.
During the use, arrange this device in the frame to with first U-shaped plate 1 spiral-lock on the lower frame of net piece frame, 2 spiral-locks of second U-shaped plate are on last frame, insert the pin during card hole and the locating hole that correspond this moment, revolve the double-end nut on the wrong telescopic link this moment, double-end nut removes slide bar 4 and pendulum rod 5 to the direction of keeping away from each other, finally make first U-shaped plate 1 hug closely with the lower frame, second U-shaped plate 2 hugs closely with last frame, support work completion this moment in. When the device is disassembled, the stud bolts 6 are reversely screwed and the pins are pulled off, so that the device can be easily disassembled from the net piece.
The utility model discloses the structure is ingenious, can fully play the supporting role to the last lower frame of net piece, and convenient the dismantlement is easily changed, convenient transport.
