Description

Technical Field

[0001] The utility model relates to the technical field of aviation plugs, and particularly relates to a fixture convenient for installing a snap ring. Background Art

[0002] The aviation plug includes a bent joint 11, a snap ring 12, and a bushing 13. As shown in the appendix Figure 1 As shown, the bent joint 11 is provided with a groove 111 for fixing the snap ring 12. The bushing 13 is sleeved on the bent joint 11. At this time, the snap ring 12 is located between the bent joint 11 and the bushing 13, forming a connection and fixing effect between the bushing 13 and the bent joint 11.

[0003] The existing installation steps among the three are as follows: The snap ring 12 is first sleeved on the bent joint 11, and then the bushing 13 and the bent joint 11 are matched through a stamping device to form a connection and fixing effect between the two. However, the problem with this installation method is that the snap ring 12 is an elastic structure. During pre-installation, the snap ring 12 cannot completely fit within the groove 111 with 100% accuracy. In other words, after the snap ring 12 is fitted with the bent joint 11, there will be partial bulges. During the installation process of the bushing 13, if the height of the bulge is relatively high, the snap ring 12 will be disengaged from the groove 111 and slide onto other parts of the bent joint 11, resulting in installation failure, and the product needs to be reinstalled or even scrapped.

[0034] Embodiment 1

[0035] This embodiment provides a fixture facilitating the installation of a snap ring. As shown in the Figures 1-4 accompanying drawings, it includes:

[0036] A body 14, the body 14 is provided with a clamping cavity 141, the snap ring 12 abuts against the side wall of the clamping cavity 141. Here, the snap ring 12 is located inside the clamping cavity 141, forming an effect of internal fixation. The clamping cavity 141 is sleeved on the elbow joint. The body 14 is located on the movement track of the screw sleeve 13. Through the setting of the clamping cavity 141, the snap ring 12 forms an effect of clamping and fixing. When the screw sleeve 13 performs stamping and fixing, the screw sleeve 13 drives the entire fixture to move. When the snap ring 12 passes through the groove 111 of the elbow joint 11, due to the increased gap, the snap ring 12 enters the groove 111. At this time, the screw sleeve 13 moves synchronously, so that the snap ring 12 is fixed inside the groove 111. The snap ring 12 is located between the screw sleeve 13 and the elbow joint 11, forming an effect of fixed installation. Compared with the installation method of the prior art, this structure can make the snap ring 12 in a stable state and improve the installation efficiency.

[0037] Specifically, in the first state, the clamping cavity 141 is set to be open; in the second state, the clamping cavity 141 is set to be closed. The clamping cavity 141 is adjustable, which is convenient for the installation of the snap ring 12. In the first state, the snap ring 12 can be quickly installed; then, by closing the clamping cavity 141, the fixing effect of the snap ring 12 is formed. In this embodiment, in the second state, the cross-section of the clamping cavity 141 is circular. In addition, the clamping cavity 141 can also be a closed chamber, but the disadvantage is that it is relatively laborious to manually install the snap ring 12.

[0038] Specifically, the inner wall of the clamping cavity 141 is smooth. Specifically, the inner wall of the clamping cavity 141 is coplanar, and the height of the clamping cavity 141 is greater than the height of the snap ring 12, so as to ensure the fixation of the snap ring 12. The diameter of the screw sleeve 13 is greater than the diameter of the clamping cavity 141.

[0039] Specifically, the clamping cavity 141 has openings on both sides. In this embodiment, taking the openings on the left and right sides as an example, it thus forms an effect of sleeving on the elbow joint 11.

[0040] Specifically, as shown in the Figure 4 accompanying drawings, the body 14 includes several components, and two adjacent components are hinged. The hinged setting forms multi-angle cooperation and can be opened or closed. Here, a sliding connection can also be used for cooperation. The number of components can be two, three, or more. In this embodiment, three components are taken as an example for description. For better description, the three components are respectively the first component 142, the second component 143, and the third component 144. The second component 143 is located between the first component 142 and the third component 144, that is, the first component 142 is hinged to the second component 143, and the second component 143 is hinged to the third component 144.

[0041] Specifically, as shown in the Figure 4 accompanying drawings, two adjacent components are provided with a rotating shaft portion 15 and a rotating shaft hole 16. The rotating shaft portion 15 cooperates with the rotating shaft hole 16, that is, one component is provided with the rotating shaft portion 15, and the other component is provided with the rotating shaft hole 16. The cooperation between the rotating shaft portion 15 and the rotating shaft hole 16 improves the stability of rotation. In this embodiment, the first component 142 and the second component 143 are cooperated through the rotating shaft portion 15 and the rotating shaft hole 16, and the second component 143 and the third component 144 are cooperated through the rotating shaft portion 15 and the rotating shaft hole 16.

[0042] Specifically, as shown in the Figure 4 accompanying drawings, the rotating shaft hole 16 is provided with a reduced diameter portion 161. The reduced diameter portion 161 forms a locking effect in the horizontal radial direction. Here, the horizontal radial direction specifically refers to the radial direction of the rotating shaft hole 16. Further, the rotating shaft hole 16 can also be locked in the axial direction of the rotating shaft hole 16 to prevent the two components from separating.

[0043] Specifically, as shown in the Figures 2-4 accompanying drawings, the body 14 further includes two handles 17, and the two handles 17 are respectively connected to two components. In this embodiment, one of the handles 17 is connected to the first component 142, and the other handle 17 is connected to the third component 144. The two handles 17 are symmetrically arranged. The handles 17 facilitate the operation of the operator. In the second state, the two handles 17 are in a fitting state, and in the first state, the two handles 17 are in an open state.

[0044] Specifically, the handle 17 and the component it is connected to are integrally formed. One of the handles 17 is integrally formed with the first component 142, and the other handle 17 is integrally formed with the third component 144.

[0045] Specifically, as shown in the Figures 1-2As shown, the elbow joint 11 is provided with a limiting portion 112, and the limiting portion 112 is located on the movement track of the main body 14. The limiting portion 112 forms a limiting effect to prevent excessive movement. However, in the actual process, when the circlip 12 enters the groove 111, the screw sleeve 13 is fixed. At this time, the circlip 12 is reset to form a limit for the screw sleeve 13, and the screw sleeve 13 will not push the main body 14 to the limiting portion 112. The limiting portion 112 only has a certain guarantee effect. At this time, by opening the main body 14, the disassembly of the fixture can be realized.

[0046] Specifically, the main body 14 is made of metal. The setting of the metal material improves the strength of the fixture. Here, the strength of the fixture is greater than that of the screw sleeve 13, so as to increase the service life of the fixture during the impact process.

[0047] Obviously, the above embodiments are only examples given for clear illustration, and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
