Quick dismounting and mounting tool for butt bolts
Technical Field
The utility model relates to the field of mechanical connector design, in particular to a rapid dismounting and mounting tool for a butt bolt.
Background
In the assembly process, the butt-joint bolts used in the brake device of the existing large civil aircraft are long in axial distance, and when the butt-joint bolts are installed and disassembled, the head of the bolts cannot be fixed by using the existing tool due to limited local space, so that the installation and the disassembly are difficult, and the assembly progress is affected.
Patent CN 212044512U provides a bolt assembly and disassembly tool in a limited space, which consists of an opening spanner head and a supporting rod, and can fix a screw through the opening spanner head when in use, and the handle is rotated to realize the disassembly and assembly of the bolt.
Patent CN 205835130U provides a bolt disassembly tool, which comprises an outer sleeve, a bolt sleeving component, a rocker and the like, wherein the outer sleeve and the bolt sleeving component are matched with a bolt when in use, and the rocker is rotated to realize bolt disassembly, but the bolt disassembly tool is difficult to use in a limited space.
Disclosure of Invention
The utility model aims to provide a novel rapid dismounting and mounting tool for a butt bolt, which solves the problems.
The technical proposal is as follows:
quick dismantlement installation frock of docking bolt includes: a handle and a fixed bent rod;
the handle is fixedly connected with one end of the fixed bent rod, and the other end of the fixed bent rod is fixedly connected with the butt bolt;
at least two 90-degree corners are arranged on the fixed bent rod.
Further, the handle is in threaded connection or welding with one end of the fixed bent rod.
Further, the other end of the fixed bent rod is provided with a convex key, and the convex key is used for fixing the sleeve and fixing the butt bolt through the sleeve.
Further, the fixed bent rod comprises a straight rod section and a bent rod section, and the straight rod section is fixedly connected with the handle and is perpendicular to the handle.
Further, the convex key is a standard convex key and is used for being matched with sleeves with different sizes.
Further, the bent rod section comprises a plurality of sub-rods, and each sub-rod is hinged with and vertically connected with the adjacent sub-rod.
Compared with the prior art, the application has the following technical effects:
1. the device is simple to manufacture and convenient to operate, can be quickly disassembled and assembled, and can be assembled by holding the handle by an installer, so that the head of the bolt is fixed by the head of the fixed bent rod, and the nut is screwed.
2. The quick and efficient bolt mounting and dismounting device is quick and efficient, saves labor, can realize quick bolt mounting and dismounting without turning the brake device in the use process, and improves efficiency.
3. The brake device has the advantages that the brake device is universal, the fixed bent rod spacing is reasonable in design, the brake device can be suitable for being installed in different sizes, meanwhile, the protruding key at the head of the bent rod is in a standard size, and the assembly of bolts with different specifications can be realized by replacing sleeves with different specifications.

Detailed Description
In order to make the technical solutions and advantages of the present utility model more apparent, the technical solutions in the embodiments of the present utility model will be described in detail and fully with reference to the accompanying drawings in which it is apparent that the described embodiments are only some embodiments, but not all embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present utility model without making any inventive effort, shall fall within the scope of the present utility model.
The utility model is described in further detail below with reference to the attached drawing figures:
referring to fig. 1-5, a novel quick dismounting and mounting tool for a docking bolt includes: handle 1, fixed bent rod 2.
Referring to fig. 2, the handle 1 and the fixed bent rod 2 are connected by a screw thread or welding mode, so that 90 degrees are formed between the handle 1 and the fixed bent rod 2.
Referring to fig. 3, the fixed bent rod 2 is provided with two 90 ° corners.
The head of the fixed bent rod 2 is provided with a convex key matched with the sleeve, the convex key adopts a universal standard size, and the bolt assembly with different specifications can be realized by replacing the sleeves with different specifications.
The operation mode is as follows:
referring to fig. 5, an operator holds the handle 1 so that the fixed bent rod 2 with the sleeve is installed to pass through the part 1 and the part 2, moves the handle 1 so that the fixed bent rod 2 with the sleeve is installed to fix the head of the docking bolt, and the other operator uses a torque wrench to tighten the nut, so that the docking bolt can be installed.
