Description
[technical field]
This utility model relates to bolt, particularly to the crimp high locked bolts of a kind of Aero-Space.
[background technology]
Along with developing rapidly of aviation industry, Closely locking nut and high locked bolts have obtained a large amount of use on military aircraft and civil aircraft.The fastening system that Closely locking nut is constituted with high locked bolts, is a kind of connection system installing, can realizing one side fastening for aircraft flaggy.Owing to Closely locking nut and high locked bolts mainly use high temperature alloy, aluminium alloy and titanium alloy etc materials to make, it has the multiple advantages such as light weight, corrosion resistance height, intensity height, compact conformation, connection be reliable, thus is widely used aboard.During use, it is common that first join brill at connecting portion and beat installing hole, then by high locked bolts through connecting hole, and Closely locking nut screwed in high locked bolts until the formation pretightning force that contacts with connecting plate, finally load the torsional moment that Closely locking nut can be made to twist into two parts, make twisting position rupture, complete to install.Existing Closely locking nut and high locked bolts typically require use torque spanner when mounted and just can complete to install, and it assembles complexity, wayward twist into two parts moment and pretightning force.
[utility model content]
This utility model aims to solve the problem that the problems referred to above, and provides a kind of self-locking property good, it is simple to the crimp high locked bolts that assembling uses.
For achieving the above object, this utility model provides a kind of crimp high locked bolts, it includes that bolt head, afterbody hexagonal hole, the bolt body of rod and bolt thread portion are formed by connecting, it is characterized in that, the outer wall in described bolt thread portion is provided with for be deformed and with Closely locking nut formed self-locking recess.
The outer wall in described bolt thread portion is interval with several described recesses.
On the outer wall in described bolt thread portion, uniform intervals is provided with 5 described recesses.
Described recess is arranged along the short transverse of high locked bolts.
Described recess is extended to the other end by the one end in bolt thread portion along short transverse.
Described recess is paralleled with the axis of described high locked bolts.
Described recess forms angle of inclination with the axis of described high locked bolts.
Favorable attributes of the present utility model is, it efficiently solves the problems referred to above.Crimp high locked bolts of the present utility model, by arranging recess on the outer wall in bolt thread portion, forms self-locking with Closely locking nut in utilizing Closely locking nut to clamp-on its recess when being deformed.Crimp high locked bolts simple in construction of the present utility model, it is easy to processing and manufacturing, and it is quick to have assembling, connects reliable feature, and it has the strongest practicality, preferably widelys popularize.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present utility model；
Fig. 2 A is this utility model high locked bolts 2 structural representation when being threaded togather with Closely locking nut 1 and crimp do not occurs；
Fig. 2 B is the high locked bolts of the present utility model 2 structural representation when being threaded togather with Closely locking nut 1 and crimp just occurring；
Structural representation when Fig. 2 C is to reach self-locking after high locked bolts 2 of the present utility model occurs crimp with Closely locking nut 1.
Wherein, Closely locking nut 1, projection 11, high locked bolts 2, bolt head 21, the bolt body of rod 22, bolt thread portion 23, recess 24, interior hexagonal hole 25.
[detailed description of the invention]
The following example is to be explained further of the present utility model and supplement, and does not constitutes any limitation this utility model.
As shown in Figure 1, Figure 2 shown in A, Fig. 2 B, Fig. 2 C, crimp high locked bolts of the present utility model, it is mainly characterized by, and is provided with the recess 24 for being deformed on the outer wall of described high locked bolts 2.As it is shown in figure 1, described high locked bolts 2 is integrally formed by connecting by bolt head 21, the bolt body of rod 22, bolt thread portion 23.Described bolt head 21, the bolt body of rod 22 can use known features and design.Being provided with interior hexagonal hole 25 in the end in described bolt thread portion 23, be provided with at least one recess 24 on the outer wall in described bolt thread portion 23, this recess 24 is for forming self-locking with self-locking nut.Described recess 24 is arranged along the short transverse of high locked bolts 2, and concrete, it is extended to its other end by the one end in bolt thread portion 23 along short transverse.Described recess 24 is paralleled with the axis of described high locked bolts, or there is certain tapering, and i.e. both form angle of inclination.In the present embodiment, on the outer wall in described bolt thread portion 23, uniform intervals is provided with 5 recesses 24, and it is uniform that it is beneficial to crimp.
Thereby, crimp high locked bolts of the present utility model is just defined.During use, as shown in Fig. 2 A～Fig. 2 C, it need to coordinate Closely locking nut 1 to use.Needing to arrange corresponding protruding 11 on the sidewall of Closely locking nut 1, when Closely locking nut 1 is inserted in the bolt thread portion 23 of high locked bolts 2, Closely locking nut 1 is threaded connection with high locked bolts 2 and links together.Now, utilize instrument, clamp Closely locking nut 1 described in the outer wall of Closely locking nut 1 knob, owing to the outer wall of Closely locking nut 1 is provided with protruding 11, therefore Closely locking nut 1 is during knob, and it makes outer wall deform upon under the extruding of instrument, so that the form of thread of Closely locking nut 1 changes；When described protruding 11 be extruded make Closely locking nut 1 deform time, it is towards radial compression and high locked bolts 2, owing to the bolt thread portion 23 of high locked bolts 2 is provided with recess 24, it can tightly be embraced the variant part of Closely locking nut 1 and form powerful self-locking, and then is greatly improved the reliability being fastenedly connected.
Although this utility model being disclosed by above example, but scope of the present utility model is not limited thereto, under conditions of conceiving without departing from this utility model, above each component can be replaced with the similar or equivalent element that art personnel understand.
