Description

TECHNICAL FIELD

[0001] The application relates to the technical field of scaffolds, in particular to a stable diagonal pull rod of a movable scaffold. BACKGROUND

[0002] The scaffold is a working platform erected to ensure the smooth progress of various construction processes. According to the position of erection, the scaffold can be divided into external scaffolds and internal scaffolds. According to different materials, the scaffold can be divided into wooden scaffolds, bamboo scaffolds and steel pipe scaffolds. According to the structural form, the scaffold can be divided into vertical rod type scaffolds, bridge type scaffolds, door type scaffolds, suspension type scaffolds, hanging type scaffolds, cantilever type scaffolds and climbing type scaffolds.

[0003] In order to ensure the stability of the metal scaffold during use, the diagonal pull rod is usually used to tighten the whole scaffold to ensure the stability of the scaffold when the user is working on the upper part. However, in the actual use process, the connection part of the scaffold diagonal pull rod is usually connected by bolts or inserted and fixed by a pin shaft. The gap between the pin shaft and the connecting hole of the pull rod end will increase due to the continuous use and shaking, which will further aggravate the shaking of the scaffold and cause certain safety hazards.

[0004] Therefore, the application provides a stable diagonal pull rod of a movable scaffold to solve the above problems. CONTENT OF THE UTILITY MODEL

[0005] The application provides a stable diagonal pull rod of a movable scaffold, which aims to solve the problems in the background art that the connection part of the scaffold diagonal pull rod is usually connected by bolts or inserted and fixed by a pin shaft in the actual use process. The gap between the pin shaft and the connecting hole of the pull rod end will increase due to the continuous use and shaking, which will further aggravate the shaking of the scaffold and cause certain safety hazards.

[0006] To achieve the above purpose, the application provides the following technical scheme: a stable diagonal pull rod of a movable scaffold, comprising a pull rod main body, a connecting part sleeved on the end part of the pull rod main body and a pin shaft for tightening the pull rod main body and the connecting part:

[0007] The both ends of the pull rod body are provided with integrally formed connecting plates, the connecting plates are provided with connecting holes with diameters larger than the pin shafts at the ends away from the pull rod body, the connecting parts are slidingly installed on the connecting plates, the connecting parts are provided with curved holes gradually reducing in caliber and extending from the ends close to the pull rod body to the ends away from the pull rod body, and the pin shafts pass through the connecting holes and the curved holes. In this way, when the scaffold is installed, the connecting parts are completely attached to the connecting plates in the initial state, the connecting parts are pushed outward when connected, the ends with larger diameters of the curved holes on the connecting parts move away from the end of the pull rod body, and the connecting holes on the connecting plates are overlapped, then the pin shafts are inserted into the connecting holes and the curved holes, then the end of the connecting part away from the end of the pull rod body is knocked in the reverse direction, the connecting part is retracted, the curved hole moves back, the end with a larger diameter of the curved hole gradually approaches the end of the pull rod body, the end with a smaller diameter of the curved hole gradually approaches the end of the pull rod body, the pin shaft is clamped on the side wall from the side, and the pin shaft is clamped in the connecting hole, so that the scaffold is prevented from shaking, when the pull rod body is loose, the end of the connecting part away from the end of the pull rod body is continuously knocked, and the pin shaft clamped in the curved hole is continuously pushed, which is more stable than bolt fixing.

[0008] Preferably, in order to adjust the angle, the pull rod body is provided with a through hinged hole at the center, and a rotating shaft is inserted into the hinged holes on every two staggered pull rod bodies. In order to adapt to the installation requirements of different scaffolds.

[0009] Preferably, in order to adapt to the pin shaft, the diameter of the end of the curved hole close to the end of the pull rod body is adapted to the connecting hole, and the diameter of the end of the curved hole away from the end of the pull rod body is smaller than the pin shaft. Different pin shafts are clamped in different positions of the curved hole, which is better in adaptability.

[0010] Preferably, in order to facilitate the movement of the connecting part, a push plate perpendicular to the connecting part is fixedly installed on the end of the connecting part close to the end of the pull rod body, and the push plate is integrally formed with the connecting part. The outward retraction of the connecting part is more convenient.

[0011] Preferably, in order to ensure the alignment of the curved hole and the connecting hole, two opposite bending plates are fixedly installed on the side of the connecting part away from the push plate, and the bending plates and the connecting part form a sliding groove adapted to the connecting plate. The alignment is accurate and reliable.

[0012] Preferably, in order to prevent the connecting part from detaching, a anti-detaching stopper is fixedly installed on the connecting plate close to the connecting hole and away from the end of the pull rod body, and the height of the anti-detaching stopper is greater than the thickness of the connecting part. The inner wall of the curved hole is blocked by the anti-detaching stopper, which is more stable and reliable.

[0013] In order to make the connecting part clamped on the connecting sheet, the gap of the slot near the one end of the pushing sheet on the chute is smaller than the gap of the slot far from the one end of the pushing sheet. Thus, the connecting part cannot shake when connected with the connecting sheet, and is more stable.

[0014] The inclined pull rod, in the initial state, the connecting part completely fits the connecting sheet. When connected, the connecting part is pushed outward, the larger diameter end of the curved hole on the connecting part moves away from the end of the pull rod main body, and coincides with the connecting hole on the connecting sheet. Then, the pin shaft is inserted into the connecting hole and the curved hole. Then, the end of the connecting part far from the end of the pull rod main body is knocked in the reverse direction, so that the connecting part retreats, the curved hole moves back, the larger diameter end of the curved hole gradually approaches the end of the pull rod main body, and the smaller diameter end of the curved hole gradually approaches the end of the pull rod main body. The side clamps the side wall of the pin shaft, so that the pin shaft is clamped in the connecting hole, thereby avoiding the shaking of the scaffold. When the pull rod main body is loose, continue to knock the end of the connecting part far from the end of the pull rod main body, and continue to push the clamped pin shaft of the curved hole. The connecting part is knocked, which is more convenient and fast than the disassembly and assembly of the bolt, and is more fastened.

[0015] When the pin shaft is removed, the connecting part is pulled away from the end of the pull rod main body. When pulled to the maximum diameter of the curved hole, it is also blocked by the anti-falling block on the inner wall of the curved hole, so that the connecting part is separated from the connecting sheet, and is more stable and reliable.
