Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description. In the preferred embodiments, the terms "upper", "lower", "left", "right", "middle" and "a" are used for the sake of clarity only, and are not intended to limit the scope of the invention, its relative relationship between the terms and their derivatives, and the scope of the invention should be understood as being limited by the claims.

As shown in fig. 1 to 7, the utility model provides an aircraft kitchen baffle fastener dismounting tool, the aircraft kitchen baffle fastener comprises a stop block 5 and a lock core which are detachably matched, the dismounting tool is used for assembling and disassembling the stop block 5 and the lock core, the lock core is arranged in a through hole of the stop block 5, a steel ball 4 which is used for locking and matching is arranged between the side wall of the lock core and the stop block 5, a pressure spring 6 which can elastically press the steel ball 4 is arranged inside the stop block 5, a positioning groove 2-1 which is tightly matched with the steel ball 4 is correspondingly arranged on the outer wall of the lock core, the dismounting tool comprises a base 1 and a guide post 3, a clamping groove 1-1 is arranged on the base 1, the clamping groove 1-1 is used for clamping and matching with the lower end of the lock core, a connecting part 3-1 is arranged at the lower end of the guide post 3, the connecting part 3-1 is used for splicing and matching with, the outer diameter of the guide post 3 is not larger than the inner diameter of the through hole and is consistent with the outer diameter of the lock cylinder, a wedge-shaped inclined surface 3-2 is arranged on the side surface of the guide post 3, and the inclined surface 3-2 is used for enabling the steel ball 4 to slide along the inclined surface 3-2 during disassembly or assembly.

In specific implementation, the number of the clamping grooves 1-1 on the base 1 is multiple, the clamping grooves 1-1 have different sizes, and due to different models of the aircraft kitchen retaining buckle, the installation and the disassembly of the kitchen retaining buckle with different models can be met by processing different clamping grooves 1-1 on the base 1.

In order to further understand the technical solution of the present invention, the working principle of the disassembling tool for assembling and disassembling the aircraft kitchen catch is described in detail below:

the assembly process of this embodiment:

placing the base 1 on a workbench, selecting a clamping groove 1-1 with a proper size, and vertically placing the lock core in the corresponding clamping groove 1-1, as shown in fig. 2 and 3; vertically inserting a guide post 3 into a lock hole in the upper part of a lock cylinder 2, sleeving a through hole of a stop block 5 on the guide post 3, and placing a steel ball 4 on an inclined plane 3-2 of the guide post 3, as shown in fig. 3 and 4; the stop block 5 and the steel ball 4 are pressed downwards along the guide post 3 from top to bottom at the same time, the steel ball 4 is pressed into the positioning groove 2-1 on the side wall of the lock core under the action of the wedge-shaped inclined surface 3-2 of the guide post 3, and the whole assembly process can be completed, at the moment, the steel ball 4 is clamped between the side wall of the lock core and the inner wall of the stop block 5, and the steel ball 4 is elastically pressed by the pressure spring 6, which is shown in fig. 4 and 5.

The disassembly process of this embodiment:

the disassembly and assembly processes are substantially the same, specifically, the base 1 is placed on a workbench, the lock core is vertically placed in the corresponding clamping groove 1-1, the base 1 is rotated, the lock core rotates about 45 degrees in the through hole of the stop block 5, so that the steel ball 4 is staggered from the position of the positioning groove 2-1, as shown in fig. 5 and 6, the lock core in fig. 6 rotates a certain angle relative to the lock core in fig. 5; the guide post 3 is vertically inserted into a lock hole at the upper part of the lock core 2, the lock core is pushed downwards by the guide post 3, the steel ball 4 slides upwards along the inclined plane 3-2 of the guide post 3, and the lock core can be pushed downwards out from the stop block 5, so that the whole disassembling process can be completed.

The aircraft kitchen blocking buckle enables the pressure spring 6 to eject the steel ball 4 to be embedded into the positioning groove 2-1 of the lock cylinder through rotating the stop block 5, so that position locking is achieved, but when the steel ball 4 rotates into the positioning groove 2-1, due to the fact that the positioning groove 2-1 has a downhill angle, the elastic force of the pressure spring 6 ejecting the steel ball 4 can generate a circumferential component force, and manual embedding is difficult to achieve. The disassembly and assembly tool of the utility model can solve the problem, so that the disassembly and assembly are more convenient; due to different models of the airplane kitchen retaining buckle, the installation and the disassembly of the kitchen retaining buckles with different models can be met only by processing different clamping grooves 1-1 on the base 1; the disassembling tool is convenient to manufacture, free of strength and hardness requirements, low in cost and wide in application range.

Although specific embodiments of the present invention have been described above, it will be appreciated by those skilled in the art that these are merely examples and that many changes and modifications may be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims.
