A nut alignment installation and removal tool for narrow spaces

Abstract

The invention discloses a nut alignment installing and detaching tool used for a narrow space. The nut alignment installing and detaching tool comprises a handle rod piece, a universal joint, a helical gear transmission mechanism, a tightening device, a stretchable mechanism, a pneumatic stretchable rod, a metal hose and a pedal control device; the handle rod piece is movably connected with the helical gear transmission mechanism through the universal joint, the helical gear transmission mechanism comprises an outer sleeve I and an outer sleeve II, the stretchable mechanism comprises an innerstretchable sleeve, an outer stretchable sleeve, a bearing, a lead screw and a lead screw motor, the tightening device comprises a worm gear, a hexagonal sleeve, a guide sleeve and a shell, and the pedal control device comprises an air inlet hose, a three-way joint, a first one-way valve, a second one-way valve, a supporting base plate and a pedal air inlet switch. The nut alignment installing anddetaching tool is simple in operation, simple and ingenious in structure and convenient to carry; and when the space around the installing device is narrow, the tool can enable a nut and a screw of awater inlet hose to be easily aligned and tightened.

Description

technical field [0001] The invention relates to the technical field of maintenance tools, in particular to a nut alignment installation and removal tool for narrow spaces. Background technique [0002] At present, the matching connection method of nuts and screws is widely used. In some places where the space is narrow and the installation position cannot be seen, it is sometimes difficult for the wrench in the prior art to install the nut correctly. For example, when the toilet is installed in reality , The water inlet needs to be installed on the toilet with a metal hose. One end of the metal hose is a hexagonal nut, and the installation position is the threaded rod at the end of the toilet float. When installing, the nut and the screw are completely coaxial, and cannot be installed sideways, otherwise the surface will be screwed on, and water will leak after the water valve is turned on. However, sometimes the space for toilet installation is very limited, and there is no...

Problems solved by technology

[0002] At present, the matching connection method of nuts and screws is widely used. In some places where the space is narrow and the installation position cannot be seen, it is sometimes difficult for the wrench in the prior art to install the nut correctly. For example, when the toilet is installed in reality , the water inlet needs to be installed on the toilet with a metal hose, one end of the metal hose is a hexagonal nut, and the installation position is the threaded rod at the end of the toilet float

When installing, the nut and the screw are completely coaxial, and cannot be installed sideways, otherwise the surface will be screwed on, and water will leak after the water valve is turned on. However, sometimes the space for toilet installation is very limited, and there is no wall around it or a cabinet has already been installed. or washbasin, etc., become the obstacle of installation, because the space is small, then blind installation is required during manual operation, which is very troublesome

When installing a new toilet, you can tighten this position first, and then install the toilet. This problem can be solved. For the toilet that has been installed and used for a period of time, it is necessary to replace the accessories due to damage to the float or metal hose. Manual replacement and installation is very troublesome, so we propose a nut alignment installation and removal tool for narrow spaces to solve the above problems
