Embodiment Construction
[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0026] Such as Figure 1 to Figure 6 Shown, a kind of pulling type hook, comprises hook rod and housing 3, and hook rod one end is crotch 1, and middle part is provided with threaded groove 2, and the other end is rotatably installed with piston 8 (piston 8 and hook rod most The simple installation method is that the hook rod and the piston 8 are connected through the anti-off bearing 6, of course, ordinary bearings can also be used and the shaft shoulder and retaining ring are added), the hook 1 is located outside the shell 3, and the thread groove 2 and the shell 3 The teeth 13 and the piston 8 are fitted in the housing 3. When the hook rod and the housing 3 are axially displaced, the teeth 13 cooperate with the thread groove 2 to make the hook rod and the housing 3 rotate relatively, and the piston 8 is installed on the side wall. There are position...

The invention relates to a stretching-type binding hook. The stretching-type binding hook comprises a binding hook rod and a shell, one end of the binding hook rod is a bent hook, the middle of the binding hook rod is provided with a threaded groove, a piston is rotatably mounted at the other end of the binding hook rod, and the bent hook is located outside the shell; the threaded groove is matched with occlusion teeth on the shell, the piston is matched in the shell, the occlusion teeth are matched with the threaded groove to make the binding hook rod and the shell rotate oppositely while thebinding hook rod and the shell do axial displacement; a positioning bead is mounted on the side wall of the piston, the inner wall of the shell is provided with a limiting hole, and the shell is internally provided with a binding hook rod reset spring; and when the binding hook rod stretches continuously from the shell, the piston continuously compresses the binding hook rod reset spring and stops compressing until the positioning bead is clamped in the limiting hole, the shell is provided with an unlocking assembly, and the unlocking assembly can enable the positioning bead to secede from the limiting hole and reset. According to the stretching-type binding hook, one-time steel bar binding can be completed only by hooking binding wires and pulling, operation is convenient, the labor intensity of construction staff is reduced, the construction efficiency of steel bar binding-wire binding is improved, and the service life is prolonged.
Description
technical field [0001] The invention relates to an auxiliary tool for engineering construction, in particular to a stretching hook. technical background [0002] The binding of steel bars is often done with wire, and hooks are generally used when binding steel bars with wire. One end of the existing tie hook is a handle, and the other end is a hook. When working, first hook the hook to tie the wire, then turn the handle to bind, and the wire can bind the steel bars firmly. This method is labor-intensive and efficient. Low. [0003] When tying wires to bind the steel bars, in addition to the hooks, the distance between the steel bars needs to be measured by a ruler. Contents of the invention [0004] The purpose of the present invention is to provide a stretching tie hook, which changes the traditional way of manually rotating and binding steel bars into a stretching binding steel bar, and only needs to hook the tie wire and pull to complete the steel bar binding once, wh...
