Description

Technical Field

[0001] This utility model relates to the field of scaffolding crossbars, and in particular to a disc-lock adjustable horizontal tie rod. Background Technology

[0002] Adjustable horizontal tie rods for scaffolding, also known as adjustable crossbars or telescopic crossbars, are horizontal members used to connect and fix scaffolding uprights. Their length can be flexibly adjusted according to construction needs to adapt to different span or height requirements. Adjustable horizontal tie rods generally consist of an outer rod and an inner rod, with one end of the outer rod threadedly connected to one end of the inner rod. Both the outer and inner rods have end-locking connectors at their other ends. In use, the adjustable horizontal tie rod is connected and fixed to the upright through the end-locking connectors, and the relative position of the outer and inner rods is adjusted by the thread to adjust the length of the adjustable horizontal tie rod to adapt to different span or height requirements. However, the threaded adjustment structure of adjustable horizontal tie rods has shortcomings: due to the complex construction site environment, the threads are constantly exposed to dust, rainwater, and concrete residue, making it easy for impurities to accumulate in the threaded adjustment structure, leading to increased adjustment resistance or even jamming and failure, seriously affecting the smoothness of operation. Utility Model Content

[0003] The main purpose of this utility model is to propose a disc buckle adjustable horizontal tie rod, which aims to solve the technical problems of existing adjustable horizontal tie rods whose threaded adjustment structure is prone to corrosion or impurity accumulation, resulting in increased adjustment resistance or even jamming and failure, affecting the smoothness of operation and low adjustment efficiency.

[0004] To achieve the above objectives, the present invention proposes a disc-lock adjustable horizontal tie rod, comprising an outer rod and an inner rod. One end of the outer rod is sleeved with one end of the inner rod. The end of the outer rod away from the inner rod is provided with a first end-locking connector, and the end of the inner rod away from the outer rod is provided with a second end-locking connector. It also includes a length adjustment structure, comprising a locking element, a locking area, and a movable area. The locking element is disposed on the outer wall of the inner rod, and the locking area and the movable area are disposed on the side wall of the outer rod. The number of locking areas is multiple, corresponding to different length nodes. All locking areas are connected to the movable area. The locking element is locked within a certain locking area or moves within the movable area.

[0005] Optionally, the locking element is a first locking block, which is vertically disposed on the outer wall of the inner rod. The first locking block includes a first positioning part and a first locking part.

[0006] The locking area is a first slot, which connects the inner wall and the outer wall of the outer rod;

[0007] The active area is the first active groove, which connects the inner wall and the outer wall of the outer rod. One side of each of the multiple first slots is connected to the first active groove.

[0008] Optionally, the first positioning part is a fixed section, which is disposed on the outer wall of the inner rod, and the first locking part is a movable section, which is rotatably connected to the fixed section. Before rotation, the movable section is located above the fixed section, and after rotation, the movable section is located on the side of the fixed section facing the first movable groove, and one side of the movable section abuts against the groove wall of the first movable groove.

[0009] Optionally, the outer edge of the active segment is designed with rounded corners.

[0010] Optionally, a boss is provided on the side of the movable section near the first movable groove, and after the movable section rotates, the bottom surface of the boss can abut against the outer wall of the inner rod.

[0011] The technical solution of this utility model has the following beneficial effects:

[0012] By incorporating a locking element, a locking zone, and a movable zone, workers can adjust the position of the locking element along the movable zone, allowing it to engage with different locking zones.

[0023] This utility model proposes an adjustable horizontal tie rod with a disc buckle. Example 1

[0024] like Figures 1 to 4 As shown in Embodiment 1 of this utility model, the adjustable horizontal pull rod includes an outer rod 100, an inner rod 200, and a length adjustment structure. Specifically, one end of the outer rod 100 is sleeved with one end of the inner rod 200. The end of the outer rod 100 away from the inner rod 200 is provided with a first end-fastening connector 110, and the end of the inner rod 200 away from the outer rod 100 is provided with a second end-fastening connector 210. Further, the length adjustment structure includes a locking member, a locking area, and a movable area. The locking member is disposed on the outer wall of the inner rod 200, and the locking area and the movable area are disposed on the side wall of the outer rod 100. The number of locking areas is multiple corresponding to different length nodes, and multiple locking areas are all connected to the movable area. The locking member is locked in a certain locking area or moves within the movable area.

[0025] It is worth noting that in this disc-lock adjustable horizontal tie rod, the first end connector 110 and the second end connector 210 are both made of vanadium-manganese alloy structural steel, which is Q355 material and has a higher strength than the ordinary carbon steel pipes of traditional scaffolding.

[0026] like Figures 1 to 4 As shown, the locking element is a first locking block 220, which is vertically disposed on the outer wall of the inner rod 200. The first locking block 220 includes a first positioning part and a first locking part. The locking area is a first slot 120, which connects the inner wall and the outer wall of the outer rod 100. The movable area is a first movable groove 130, which connects the inner wall and the outer wall of the outer rod 100. One side of each of the multiple first slots 120 is connected to the first movable groove 130. In this embodiment, the length is adjusted by the first positioning part cooperating with different first slots 120, and the current length is locked after adjustment by the first locking part cooperating with the first movable groove 130.

[0027] Specifically, the first positioning part is a fixed section 2201, which is disposed on the outer wall of the inner rod 200. The first locking part is a movable section 2202, the outer edge of which is rounded. The movable section 2202 is rotatably connected to the fixed section 2201. Furthermore, a boss 22021 is provided on the side of the movable section 2202 near the first movable groove 130. When the movable section 2202 rotates, the bottom surface of the boss 22021 can abut against the outer wall of the inner rod 200, thereby improving the stability of the locking.

[0028] When locked, the movable segment 2202 is positioned above the fixed segment 2201 before rotation. At this time, the worker can move the inner rod 200 via the first locking block 220, select the first slot 120 that meets the length requirement via the first movable groove 130, and move the first locking block 220 into the first slot 120. Then, the movable segment 2202 is rotated so that it faces the side of the fixed segment 2201 towards the first movable groove 130, causing one side of the movable segment 2202 to abut against the groove wall of the first movable groove 130, thereby locking the current length. In this embodiment, the movable segment 2202 is hinged to the fixed segment 2201 via a shaft to achieve rotation around the shaft. In other embodiments, the movable segment 2202 can be rotatably connected to the fixed segment 2201 via a hinge or other means.

[0029] Specifically, the working principle and process of this utility model are as follows:

[0030] By incorporating a locking element, a locking zone, and a movable zone, workers can adjust the position of the locking element along the movable zone, allowing it to engage with different locking zones. This enables the adjustment of the length of the adjustable horizontal tie rod and locks it at that length. The space in the locking and movable zones is much larger than the thread pitch, preventing dust and other contaminants from accumulating in these areas or on the locking element. Furthermore, all three are easy to clean. Therefore, this length adjustment structure avoids dust accumulation, which can increase adjustment resistance or even cause jamming and failure, thus ensuring smooth operation of the length adjustment over the long term.

[0031] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
