[0023] Example
[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the problem that the crowbar body has a fixed length and cannot be disassembled, and the crowbar with a fixed length may not be suitable for all working occasions and is difficult to carry and store. The overall idea is as follows:
[0025] In view of the problems existing in the prior art, the utility model provides a multifunctional crowbar for removing formwork, comprising a main rod 1, a connecting rod 2 3 is arranged above the main rod 1, a connecting rod 1 2 is arranged below the main rod 1, two connecting rings 2 13 are arranged on the annular side of the main rod 1, the backs of the two connecting rings 2 13 are fixedly connected to connecting rings 1 8, a back hook 6 is arranged on the annular side of the connecting rod 1 2, a groove 14 is provided on the annular side of the connecting rod 1 2, a bolt 16 is movably sleeved in the groove 14, slots 10 are provided on the opposite surfaces of the connecting rod 2 3 and the connecting rod 1 2, and the two slots 10 are movably sleeved with the main rod 1. When the formwork needs to be removed, the curved hook 4 or the pointed head 5 is selected for use according to the on-site environment. The curved hook 4 is used to hang the edge or corner of the formwork for easy removal, and the pointed head 5 is used to apply force in a narrow space or at a connection so as to separate the formwork.
[0026] Two thread grooves 2 11 are provided on the annular side of the main rod 1, and the two thread grooves 2 11 are respectively threadedly sleeved with two connecting rings 2 13; thread grooves 19 are provided on the opposite ends of the connecting rod 2 3 and the connecting rod 1 2, and the two thread grooves 9 are respectively threadedly sleeved with two connecting rings 8; a hook 4 is fixedly connected to the upper surface of the connecting rod 2 3, and a pointed head 5 is fixedly connected to the lower surface of the connecting rod 2; a fixing ring 12 is fixedly connected to the annular side of the main rod 1, and a handle 7 is fixedly connected to the annular side of the connecting rod 2 3. Before use, the connecting ring 13 fixed thereto is driven to rotate together by rotating the connecting ring 18 downward. At this time, the connecting ring 18 will be disengaged from the sleeve of the thread groove 9 provided on the connecting rod 2 3, and the limit is opened. The connecting rod 2 3 can be telescopically moved and adjusted to a suitable length according to needs, which improves the operator's comfort while meeting different working scenarios and improves practicality.
[0027] A connecting block 17 is fixedly connected to the left surface of the back hook 6, and the connecting block 17 is movably engaged with the slot 14. Threaded holes 15 are penetrated on the surfaces of the back hook 6 and the connecting block 17, and the two threaded holes 15 are movably connected with the bolts 16. A back hook 6 is provided on the connecting rod 2, and the back hook 6 can be used as a lifting, dragging or fixing tool, which increases the overall functionality. When the back hook 6 is not needed, it can be removed by disassembling the bolts 16 to reduce the volume and weight when carrying. Both the connecting rod 2 3 and the connecting rod 1 2 can be disassembled by rotating the connecting ring 1 8 to open the limit, and split them into smaller parts for easy carrying and transportation. If a part of the crowbar is damaged, only the damaged part can be replaced without replacing the entire crowbar, thereby reducing the maintenance cost.
[0028] Working principle:
[0029] When the formwork needs to be removed, the hook 4 or the pointed head 5 is selected for use according to the on-site environment. The hook 4 is used to hang the edge or corner of the formwork for easy removal, and the pointed head 5 is used to apply force in a narrow space or connection to separate the formwork. Before use, the connecting ring 18 is rotated downward to drive the connecting ring 2 13 fixed thereto to rotate together. At this time, the connecting ring 18 will be separated from the sleeve of the threaded groove 19 opened on the connecting rod 23, and the limit is opened. The connecting rod 23 can be telescopically moved and adjusted to a suitable length according to needs, which improves the operator's comfort while meeting the requirements. Different working scenarios improve practicality. A back hook 6 is provided on the connecting rod 2, which can be used as a lifting, dragging or fixing tool, increasing the overall functionality. When the back hook 6 is not needed, it can be removed by disassembling the bolt 16 to reduce the volume and weight when carrying. Both the connecting rod 2 3 and the connecting rod 1 2 can be disassembled by rotating the connecting ring 1 8 to open the limit and split them into smaller parts for easy carrying and transportation. If a part of the crowbar is damaged, only the damaged part can be replaced without replacing the entire crowbar, reducing the maintenance cost.
[0030] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
