Description

Safe adjustable support Technical Field The utility model relates to the field of brackets, in particular to a safe and adjustable bracket. Background The disc buckle type scaffold is a common modern scaffold system, has the advantages of simple structure, quick installation, high stability and the like, and mainly comprises upright rods, cross rods, inclined struts, disc buckles, supporting struts, scaffold plates, safety fences and joint pieces, wherein the adjustable supporting struts in the disc buckle type scaffold are important parts and are mainly used for providing supporting force of the scaffold and allowing adjustment of the height and the position in the construction process, and the adjustable supporting struts generally comprise an adjusting mechanism, such as a threaded rod and an adjusting device, so that the length or the angle of the adjustable supporting struts can be adjusted within a certain range, and the adjusting device is generally composed of a threaded cylinder and a rotating block fixed on the threaded cylinder. According to the utility model, according to the Chinese patent with the publication number of CN221703113U, a slidable toothed plate is arranged in a rotary drum, when the rotary drum needs to be adjusted at a large distance from the surface of a screw rod, the toothed plate is retracted into the rotary drum, the rotary drum can slide freely on the surface of the screw rod, after the rotary drum is adjusted to a proper position, the toothed plate is extended and meshed with the screw rod, and finally, the rotary drum is accurately adjusted through the rotary plate, so that the adjusting time is shortened, and the complicated operation in the adjusting process is reduced. To above-mentioned published patent content, through being provided with screw rod and adjustable nut, adjustable nut can remove on the screw rod when rotating adjustable nut to realize adjustably, and the screw rod position of adjustable nut top can insert in the pole setting when the support is in use, but the screw rod position of adjustable nut below is always exposed in the external environment, and because the support generally is arranged in the building construction place, dust impurity is more, leads to dust or impurity to can get into the screw thread inslot of the screw rod that exposes in the external environment, can lead to follow-up difficult to adjust the height of adjustable nut when dust or impurity in the screw thread inslot piles up more, can make adjustable nut appear the jamming condition, and then influence the result of use of support. Disclosure of utility model Based on the above, the utility model aims to provide a safe adjustable support so as to solve the technical problem that external dust or impurities can enter into a thread groove of a screw rod to influence the subsequent adjustment of the height of an adjustable nut. In order to achieve the above purpose, the safe adjustable support comprises a bottom plate, wherein a screw is arranged at the top of the bottom plate, an adjustable nut is connected to the outer wall of the screw in a threaded mode, a first mounting plate is arranged at the bottom of the adjustable nut through a first locking bolt, a sliding groove is formed in the bottom of the first mounting plate, a sliding ring is arranged in the sliding groove, a first sealing ring is arranged at the bottom of the sliding ring, a second mounting plate is arranged at the top of the bottom plate through a second locking bolt, a second sealing ring is fixed at the top of the second mounting plate, and a protective cloth barrel is connected between the second sealing ring and the first sealing ring.
