Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, in particular to a steel structure with a telescopic structure. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. Steel structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing.

[0003] At present, most of the steel structures in the existing technology do not have the characteristic of being retractable, while steel structures with retractable structures usually have high adaptability and flexibility to meet different operational requirements. In view of this, we propose a steel structure with a retractable structure. Utility Model Content

[0004] The main purpose of the utility model is to provide a steel structure with a telescopic structure, which can solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model proposes a steel structure with a telescopic structure, including a steel body 1, wherein the steel body 1 is movably connected to a steel body 2 inside, an L-shaped plate is fixedly connected below the steel body 1, and the L-shaped plate is threadedly connected to a bolt, and an auxiliary mechanism is provided on the steel body 1, and the auxiliary mechanism includes:

[0006] A connecting plate is fixedly connected to an outer wall of the steel body, an end of the connecting plate away from the outer wall of the steel body is fixedly connected to an oil tank, an oil filling port is provided on the oil tank, and a second circular hole is provided below the oil tank.

[0007] Preferably, a fixing plate is fixedly connected above the oil tank, an elastic telescopic rod is fixedly connected to the fixing plate, and a trapezoidal block 1 is fixedly connected to one end of the elastic telescopic rod away from the fixing plate.

[0008] Preferably, the trapezoidal block 1 is movably connected to the trapezoidal block 2, and the trapezoidal block 2 is fixedly connected to the outer wall of the steel body 2.

[0009] Preferably, a round rod is fixedly connected below the trapezoidal block, a slide is fixedly connected to one end of the round rod away from the trapezoidal block, a round hole is provided on the slide, sliders are fixedly connected to both ends of the outer wall of the slide, the sliders are slidably connected to a slide groove, and the slide groove is provided on the inner wall of the oil tank, the round rod is slidably connected to a movable groove, and the movable groove is provided above the oil tank.

[0010] Preferably, both ends of the two outer walls of the steel body are provided with through grooves, the through grooves are rotatably connected with gears, the gears are meshed with racks, and the racks are fixedly connected to an inner wall of the steel body.

[0011] Preferably, a screw is threadedly connected to the lower part of the second steel body, a rotating rod is fixedly connected to the lower part of the screw, and a handle is fixedly connected to the end of the rotating rod away from the screw. The bolt is released from the position limit of the handle by turning the bolt outward, and then the handle is turned to drive the rotation of the rotating rod. The rotation of the rotating rod will drive the rotation of the screw. With the cooperation of the through groove, the gear and the rack, the rotation of the screw will drive the second steel body to telescope. When the second steel body moves upward, it will drive the second trapezoidal block to move upward together. The upward movement of the second trapezoidal block will touch the first trapezoidal block, and the movable groove, the round rod, the slide groove and the slider will be moved upward. The cooperation will drive the skateboard to slide. During the sliding of the skateboard, the circular hole 1 on the skateboard will overlap with the circular hole 2 under the fuel tank. When the circular hole 1 overlaps with the circular hole 2, the lubricating oil in the fuel tank will flow along the circular hole 2 under the fuel tank to the gear and rack below and lubricate them, effectively preventing the aging problem of the gear and rack. The continued sliding of the skateboard will separate the circular hole 1 from the circular hole 2, thereby blocking the circular hole 2 under the fuel tank to avoid oil leakage. At this time, the bolt is rotated in the opposite direction to limit the position of the handle, thereby ensuring the stability of the positional relationship between the steel body 1 and the steel body 2.

[0012] The utility model provides a steel structure with a telescopic structure. It has the following beneficial effects:

[0013] (1) The steel structure with a telescopic structure releases the position limit of the handle by turning the bolt outward, and then turns the handle to drive the rotation of the rotating rod. The rotation of the rotating rod will drive the rotation of the screw rod. Under the cooperation of the through groove, gear and rack, the rotation of the screw rod will drive the steel body 2 to perform telescopic action. When the steel body 2 moves upward, it will drive the trapezoidal block 2 to move upward together. The upward movement of the trapezoidal block 2 will touch the trapezoidal block 1, and under the cooperation of the movable groove, round rod, sliding groove and sliding block, it will drive the slide plate to slide. During the sliding process of the slide plate, the circular hole 1 on the slide plate will overlap with the circular hole 2 under the oil tank. When the circular hole 1 overlaps with the circular hole 2, the lubricating oil in the oil tank will flow along the circular hole 2 under the oil tank to the gear and rack below and lubricate them, effectively preventing the aging problem of the gear and rack.

[0014] (2) The steel structure with the telescopic structure will continue to slide through the slide plate to separate the circular hole 1 from the circular hole 2, thereby covering the circular hole 2 under the oil tank to prevent oil leakage. At this time, the bolt is rotated in the opposite direction to limit the position of the handle, thereby ensuring the stable position relationship between the steel body 1 and the steel body 2.
