Abstract
Description
Technical Field
[0001] This utility model specifically relates to a testing auxiliary device for aircraft maintenance, belonging to the field of aircraft maintenance technology. Background Technology
[0002] Aircraft maintenance is a technical position that ensures the safe operation of aircraft through system inspection, fault diagnosis and component repair. Its core functions include line maintenance, scheduled overhaul and flight control device calibration.
[0003] According to application number 201921862350.3, a novel auxiliary device for aircraft maintenance is disclosed, including a toolbox. The toolbox is divided into a parts cavity and a tool cavity by a partition. The parts cavity is located directly above the tool cavity. Both the parts cavity and the tool cavity have symmetrically arranged spherical grooves on their side walls. Each spherical groove contains a matching spherical slider. The inner side walls of both the parts cavity and the tool cavity have strip-shaped openings communicating with the spherical grooves, and the width of the strip-shaped openings is smaller than the width of the inner diameter of the spherical grooves. The parts cavity and the tool cavity each contain a parts drawer and a tool drawer, respectively. Symmetrically positioned connecting rods are provided on the side walls of both the parts drawer and the tool drawer. This utility model has a simple structure and multiple functions. The size of the compartments in the tool drawer can be adjusted according to the size of the tools, preventing the loss of small bolts and screws during aircraft maintenance.
[0004] The above-mentioned solution still has certain shortcomings in actual use. In the operation of aircraft maintenance, there are a large number of bolts and screws that need to be removed. Some bolts and screws need to be removed by workers with the help of ladders. If the existing device is used to store the screws and bolts, workers need to frequently come down the ladder to store the bolts. This process is not only cumbersome, but also poses a risk of falling while workers are going up and down the ladder. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of the existing technology by providing an auxiliary testing device for aircraft maintenance, comprising two mounting blocks. A fixing component is mounted on the outer surface of the two mounting blocks, and a storage component is mounted on the other side of the two mounting blocks. The storage component includes a collection box installed between the two mounting blocks. Two opening and closing plates are hinged to the upper surface of the two collection boxes, and a handle is fixedly connected to the upper surface of each of the two opening and closing plates.
[0006] Furthermore, the fixing component includes a fixing rope passing through the two mounting blocks, and the outer surface of the fixing rope is provided with meshing teeth.
[0007] Furthermore, a connecting block is fixedly connected to one end of the fixing rope, and a square groove is formed on the outer surface of the connecting block.
[0008] Furthermore, a sliding rod is slidably connected inside the square groove, and a gear plate is fixedly connected to one end of the sliding rod.
[0009] Furthermore, the gear plate is engaged with the meshing teeth, and a spring is installed between the gear plate and the inner wall of the square groove.
[0010] Furthermore, a circular plate is fixedly connected to the other end of the slide rod, and a rubber sleeve is fitted on the outer surface of the circular plate.
[0011] Furthermore, a horizontal plate is installed inside the collection box, and a set of partitions is fixedly connected to the upper surface of the horizontal plate.
[0012] Beneficial effects:
[0013] By combining mounting blocks, fixing components, and storage components, the fixing components allow workers to wear the device, while the storage components collect the bolts after disassembly. This eliminates the need to climb down a ladder to store bolts when disassembling bolts at heights, simplifying the operation and reducing the risks associated with bolt disassembly.
[0014] The collection box, opening and closing plate, handle, horizontal plate, and partition are designed to collect bolts. The opening and closing plate allows the collection box to be opened and closed. The horizontal plate and partition allow the bolts to be sorted after disassembly, making them easier to use later.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-3 As shown, an auxiliary testing device for aircraft maintenance includes two mounting blocks 1. A fixing component 2 is mounted on the outer surface of the two mounting blocks 1. The fixing component 2 includes a fixing rope 201 that passes through the two mounting blocks 1. The fixing rope 201 can be worn by the operator, which facilitates the subsequent disassembly of bolts and ensures the normal use of the device.
[0021] The outer surface of the fixing rope 201 is provided with meshing teeth 202. The meshing teeth 202 facilitate subsequent locking and limiting, thereby ensuring the wearing effect of the fixing rope 201.
[0022] One end of the fixing rope 201 is fixedly connected to a connecting block 203. A square groove 204 is opened on the outer surface of the connecting block 203. A slide rod 205 is slidably connected inside the square groove 204. A gear plate 206 is fixedly connected to one end of the slide rod 205. The gear plate 206 is engaged with the meshing teeth 202. A spring 207 is installed between the gear plate 206 and the inner wall of the square groove 204. Through the engagement between the gear plate 206 and the meshing teeth 202, and by utilizing the elastic force provided by the spring 207 on the slide rod 205, the engagement effect between the gear plate 206 and the meshing teeth 202 can be guaranteed, thereby ensuring the wearing effect for subsequent workers.
[0023] The other end of the slide rod 205 is fixedly connected to a circular plate 208, and the outer surface of the circular plate 208 is covered with a rubber sleeve. The circular plate 208 can limit the movement of the slide rod 205 to a certain extent, thereby ensuring the sliding effect of the slide rod 205. At the same time, the rubber sleeve can prevent slippage during the pulling process, thus ensuring the normal use of the device.
[0024] A storage component 3 is installed on the other side of both mounting blocks 1. The storage component 3 includes a collection box 301 installed between the two mounting blocks 1. The collection box 301 can store the bolts after disassembly, thereby ensuring the efficiency of disassembly and maintenance.
[0025] The upper surfaces of the two collection boxes 301 are hinged with two opening and closing plates 302. The opening and closing plates 302 can close the collection boxes 301 to ensure the effectiveness of subsequent use of the collection boxes 301.
[0026] A handle 303 is fixedly connected to the upper surface of both opening and closing plates 302, and the handle 303 can provide a certain degree of convenience for opening the opening and closing plates 302.
[0027] The collection box 301 has a horizontal plate 304 installed inside. A set of partitions 305 are fixedly connected to the upper surface of the horizontal plate 304. The horizontal plate 304 can be used to place the bolts after disassembly, and the partitions 305 can be used to classify the bolts, making it convenient for the staff to take them out later.
[0028] As a technical optimization of this utility model, when the staff needs to disassemble the bolts at a high position, first insert one end of the fixing rope 201 into the inside of the square groove 204. At the same time as insertion, pull the circular plate 208, and the sliding rod 205 will be displaced. Then pull one end of the fixing rope 201 over, and then put this device on the staff. Then release the circular plate 208, and then use the elastic force of the spring 207 to realize the engagement between the gear plate 206 and the meshing teeth 202, thereby realizing the limitation of the fixing rope 201, thus realizing the wearing of this device. Then, the bolts that need to be disassembled on the aircraft are disassembled through the ladder. The disassembled bolts are placed on the surface of the horizontal plate 304, thus completing the disassembly and storage of the bolts.
