Abstract
Description
Technical Field
[0001] This utility model relates to a self-locking nut for a floating support plate, specifically a self-locking nut for a double-eared support plate with a large floating range. Background Technology
[0002] In the aerospace field, the mechanical structure of equipment is generally subject to high requirements. Traditional self-locking nuts are prone to loosening when subjected to vibration, impact and complex external loads, which can lead to loss of clamping force between connected parts and cause structural failure. Traditional self-locking nuts cannot meet the problem of reliable connection of large-movement parts and cannot ensure the stable operation of related equipment in complex environments. Utility Model Content
[0003] To overcome the above-mentioned defects, the purpose of this utility model is to provide a large-moment double-ear self-locking nut, which can effectively solve the problem that traditional self-locking nuts cannot meet the reliable connection of large-moment components, and ensure the stable operation of related equipment in complex environments.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A large-move double-ear self-locking nut includes a bracket and a movable self-locking nut. The bracket includes a snap-fit part and a connecting part. The snap-fit part includes a support plate and folded plates disposed on both sides of the support plate. The support plate has a waist-shaped hole, and the folded plates are used to snap the movable self-locking nut.
[0006] Preferably, the connecting part includes connecting plates disposed on both ends of the tray, and connecting holes are formed on the connecting plates.
[0007] Preferably, the connecting hole is a threaded hole or a riveting hole.
[0008] Preferably, a groove is formed at one end of the folding plate near the waist-shaped hole.
[0009] Preferably, the movable self-locking nut includes a nut and a support plate disposed on the outer circular surface of the nut. The support plate is flush with the bottom end of the nut and is disposed on a support plate. The nut is engaged with the groove.
[0010] Preferably, the support plate has two grooves on its two sides near the connecting hole.
[0011] The positive and beneficial effects of this utility model are as follows:
[0012] 1. This utility model's large-momentum self-locking nut for a support plate can adapt to the relative displacement between connecting parts within a certain range, reducing the additional stress caused by component movement. It not only effectively prevents the nut from loosening, ensuring a stable connection between components, but also maintains good connection performance even with relative displacement between connecting parts, better adapting to dynamic connection environments. Furthermore, this utility model's large-momentum self-locking nut for a support plate has a support plate structure, which can distribute the load and provide a certain degree of support in dynamic and complex environments such as impact and vibration. Therefore, this utility model's large-momentum double-ear support plate self-locking nut can effectively solve the problem that traditional self-locking nuts cannot meet the reliable connection requirements of components with large momentum, ensuring the stable operation of related equipment in complex environments. It also has a simple structure, low processing cost, and is suitable for mass production. Attached Figure Description

[0018] The present invention will be further described below with reference to some specific embodiments.
[0019] Example 1
[0020] See Figure 1-3 A large-move double-ear self-locking nut includes a bracket 1 and a movable self-locking nut 2. The bracket 1 includes a snap-fit part 11 and a connecting part 12. The snap-fit part 11 includes a support plate 111 and folding plates 112 disposed on both sides of the support plate 111. A waist-shaped hole 113 is opened on the support plate 111. The folding plates 112 are used to snap the movable self-locking nut 2.
[0021] Furthermore, the connecting part 12 includes connecting plates 121 disposed on both ends of the support plate 111, and connecting holes 122 are provided on the connecting plates 121, through which the large-movement double-ear support plate self-locking nuts are fixed to the connecting parts.
[0022] Furthermore, the connecting hole 122 is a riveting hole, which is used to fix the self-locking nut of the movable double-ear support plate to the connector by means of rivets, making operation convenient.
[0023] Furthermore, a groove 114 is provided on the end face of the bent surface of the folding plate 112 near the waist-shaped hole 113, and the floating self-locking nut 2 is engaged by the opposing grooves 114 on both sides of the folding plate 112.
[0024] Furthermore, the movable self-locking nut 2 includes a nut 21 and a support plate 22 disposed on the outer circular surface of the nut 21. The support plate 22 is flush with the bottom end of the nut 21 and is disposed on the support plate 111. The outer circular surface of the nut 21 is engaged with the groove 114, and the nut 21 can move within the groove 114 of the folding plate 112.
[0025] Furthermore, grooves 221 are provided on both sides of the support plate 22 near the connection hole 122 to prevent the support plate 22 from causing spatial interference to the connection of the connection hole 122.
[0026] The method of using the self-locking nut for the large-momentum support plate of this utility model is as follows: See [link / reference needed] Figure 4 First, the self-locking nut 2 is placed in the oblong hole 113 of the support plate 111. Then, the folding plate 112 is bent and stamped. The self-locking nut 2 and the bracket 1 are clamped together by the folding plate 112. Next, the rivet is fixed to the self-locking nut of the self-locking double-ear support plate on the connector through the rivet hole 122. Finally, the bolt 3 is connected by passing through the mounting hole on the connector, the oblong hole 113 on the bracket 1 and the threaded hole of the nut 21 of the self-locking nut 2. Since the self-locking nut 2 has a large lateral movement in the bracket 1, the installation accuracy of the rivet is not very high, which reduces the installation difficulty of the bolt 3. The self-locking nut of the self-locking double-ear support plate with a large movement can not only ensure that the self-locking nut 2 can move freely within a certain range, thereby achieving a large movement, but also ensure that the self-locking nut 2 will not shake in the bracket 1.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
