Description

Technical Field

[0001] This utility model relates to the field of connector installation technology, and in particular to a high-locking bolt installation tool for confined spaces. Background Technology

[0002] In the modern aerospace manufacturing industry, high-strength bolts are a commonly used standard part, distributed on various structural surfaces. High-strength bolts are mainly installed using a high-strength bolt installation gun or manually, but this is only suitable for scenarios with ample operating space. In semi-enclosed, confined structures, manual installation of high-strength bolts requires using both hands to hold the internal hex wrench and turn the external hex wrench, which is complicated. Furthermore, the tools are prone to falling off during the installation process, requiring repeated fixing. In addition, due to the limited operating space, it is inconvenient to operate with both hands, which leads to low installation efficiency. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a high-locking bolt installation tool for confined spaces, so as to solve the problems in the background art mentioned above.

[0004] The technical problem solved by this utility model is achieved by the following technical solution:

[0005] A high-lock bolt installation tool for confined spaces includes a fixed handle, an internal hexagonal core rod, and a movable ratchet handle. The fixed handle is threadedly connected to the internal hexagonal core rod, and the movable ratchet handle is threadedly connected to the fixed handle. Each of the fixed handle and the movable ratchet handle has a handle hole for rotating. The specific structure of each part is as follows:

[0006] The fixed handle includes a fixed core rod mounting thread, a fixed handle rotation thread, and a fixed handle body. The core rod mounting thread is used to connect with the internal hexagon core rod, and the handle rotation thread is connected with the movable ratchet handle.

[0007] The internal hexagonal core rod includes a core rod mounting thread, a core rod body, and an internal hexagonal head. One end of the core rod body is provided with a core rod mounting thread, and the other end of the core rod body is provided with an internal hexagonal head. The core rod mounting thread is connected to the fixed core rod mounting thread, and the internal hexagonal head is used to fix the high-strength bolt.

[0008] The movable ratchet handle includes a movable handle rotation thread, a ratchet, and a movable handle. The movable handle rotation thread is connected to the fixed handle rotation thread, and the ratchet is used to hold the nut.

[0009] In this invention, the rotating thread of the fixed handle is located around the mounting thread of the fixed core rod.

[0010] In this utility model, a boss is provided at one end of the movable handle, and a rotating thread and a ratchet are provided inside the boss.

[0011] In this invention, the ratchet on the movable ratchet handle is used to tighten the nut when the movable ratchet handle is rotated clockwise, and to keep the nut stationary when rotated counterclockwise. That is, the movable ratchet handle installs the high-lock bolt by partially rotating back and forth. The back and forth rotation of the movable ratchet handle is mainly achieved by the thread and ratchet between the movable handle and the fixed handle, thereby achieving the purpose of fixing the high-lock bolt in place with the internal hexagonal core rod and installing the nut with the movable ratchet handle, thus realizing the installation of the high-lock bolt with one hand.

[0012] Beneficial effects: This utility model effectively solves the problem of difficult installation of high-locking bolts in narrow spaces. The entire operation can be carried out with one hand, and there is no need to worry about the hexagonal core rod falling off. It is simple to operate and has high installation efficiency.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0019] See Figures 1-5 A high-lock bolt installation tool for confined spaces includes a fixed handle 1, an internal hexagonal core rod 2, and a movable ratchet handle 3. The fixed handle 1 is threadedly connected to the internal hexagonal core rod 2, and the movable ratchet handle 3 is threadedly connected to the fixed handle 1. Handle holes are provided on both the fixed handle 1 and the movable ratchet handle 3 for rotating them. The specific structures of each part are as follows:

[0020] The fixed handle 1 includes a fixed core rod mounting thread 1-1, a fixed handle rotation thread 1-2, and a fixed handle body 1-3. One end of the fixed handle body 1-3 is provided with the fixed core rod mounting thread 1-1 and the fixed handle rotation thread 1-2, and the other end of the fixed handle body 1-3 is provided with a handle hole. The core rod mounting thread 1-1 is used to be threadedly connected to the internal hexagonal core rod 2, and the handle rotation thread 1-2 is threadedly connected to the movable ratchet handle 3.

[0021] The internal hexagonal core rod 2 includes a core rod mounting thread 2-1, a core rod body 2-2, and an internal hexagonal head 2-3. One end of the core rod body 2-2 is provided with the core rod mounting thread 2-1, and the other end of the core rod body 2-2 is provided with the internal hexagonal head 2-3. The core rod mounting thread 2-1 is connected to the fixing core rod mounting thread 1-1, and the internal hexagonal head 2-2 is used to fix the high-strength bolt.

[0022] The movable ratchet handle 3 includes a movable handle rotation thread 3-1, a ratchet 3-2, and a movable handle 3-3. The movable handle rotation thread 3-1 is connected to the fixed handle rotation thread 1-2, and the ratchet 3-2 is used to hold the nut.

[0023] In this embodiment, the fixed handle rotation thread 1-2 is disposed around the fixed core rod mounting thread 1-1.

[0024] In this embodiment, a boss is provided at one end of the movable handle 3-3, and a handle hole is provided at the other end of the movable handle 3-3. The boss is provided with a movable handle rotation thread 3-1 and a ratchet 3-2.

[0025] In this embodiment, the installation tool is first assembled. The internal hexagonal core rod 2 and the fixed handle 1 are combined and fixed by the core rod mounting thread 2-1 and the fixed core rod mounting thread 1-1. Then, the fixed handle 1 and the movable ratchet handle 3 are combined by the movable handle rotation thread 3-1 and the fixed handle rotation thread 1-2, but the threads should not be tightened to the end. After the installation tool is assembled, it is placed on the high-lock nut. The internal hexagonal head 2-3 of the internal hexagonal core rod 2 fixes the high-lock bolt, and the ratchet 3-2 holds the nut. The operator can tighten the nut by turning the movable handle 3-3 clockwise with one hand through the handle hole on the movable ratchet handle 3. Turning the movable handle 3-3 counterclockwise will prevent the nut from turning or being subjected to force due to the action of the ratchet 3-2. That is, only one hand is needed to operate, so that the fixed handle 1 and the movable ratchet handle 3 form a "scissor"-like movement. The movable handle 3-3 moves back and forth in a partial manner to smoothly tighten the high-lock nut and complete the installation of the high-lock bolt.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
