Description
Technical field
The invention belongs to connector technical field, and in particular to a kind of antitheft antidetonation setscrew.
Background technology
Screw rod, nut and the expansion tube of existing conventional expanded bolt are basic module.Operation principle：Screw rod tail is circular cone
Shape.The internal diameter of circular cone is more than the internal diameter of expansion tube, and screw rod is displaced outwardly when nut is tightened, and passes through the axial movement of screw thread
Tapered segment is moved, and then very big normal pressure is formed in the periphery of expansion tube, the angle very little of circular cone makes wall swollen in addition
Friction self-locking, and then fixation are formed between tube expansion and circular cone.
The shortcomings that existing expansion bolt：First, existing expansion bolt, if load has larger vibrations, can destroy expansion tube,
The friction self-locking that wall, tapered tail are formed, it is likely that make expansion bolt loosen or even come off, there is potential safety hazard.2nd, it is existing
Having expansion bolt that nut can be unloaded to rotation screw rod destruction friction self-locking under the conditions of artificial external force makes overall loosen so as to quilt
Artificially unload, load object safety can not be ensured.3rd, existing expansion bolt is artificially beaten using being preceding required for using electric drill perforating
Eye is whard to control, it is difficult to control perforating weight.If not getting suitable depth, expansion bolt can be influenceed and tightened in nut
Screw rod is displaced outwardly the effect of caused friction self-locking, be unable to reach real friction self-locking.
The content of the invention
It is contemplated that at least solves one of technical problem present in prior art.Prevent therefore, the present invention provides one kind
Steal antidetonation setscrew, it is therefore an objective to make setscrew that loose or dislocation will not occur when load shakes.
To achieve these goals, the technical scheme taken of the present invention is：
A kind of antitheft antidetonation setscrew, including screw rod and cap nut, the setscrew also include top and are coated at
The expansion loop of screw rod, the top are connected with screw rod one end, and top is provided with elastic locking mechanism, and the cap nut drives expansion
Axial direction of the circle along screw rod moves towards top.
The top includes solid top and hollow top, and the hollow top is connected by solid top with screw rod.
The elastic locking mechanism includes cylinder and the spring in hollow top, and the cylinder is embedded in hollow top
Contacted with spring extruding.
The hollow top comes directly towards for rectangle hollow.
The cylinder is two, and two cylinders are rabbeted in hollow top from the both ends of hollow top respectively, and two posts
The embedding incoming end of body contacts with spring.
The interlocking end of the cylinder is provided with the extension iron plate of anti-ejection.
The cylinder is solid cylinder.
The screw rod, solid top, hollow top are structure as a whole.
Beneficial effects of the present invention：When load shakes loose or dislocation will not occur for the setscrew of the present invention, easily control
Perforating processed, expansion, it is ensured that the safety of load thing and the safety of personal property.
Brief description of the drawings
This specification includes the following drawings, and shown content is respectively：
Fig. 1 is the structural representation of the present invention.
In figure mark for：
1st, screw rod, 2, cap nut, 3, expansion loop, 4, solid top, 5, cylinder, 6, hollow top, 7, spring.
Embodiment
Below against accompanying drawing, by the description to embodiment, embodiment of the invention is made further details of
Explanation, it is therefore an objective to help those skilled in the art to have more complete, accurate and deep reason to design of the invention, technical scheme
Solution, and contribute to its implementation.
As shown in figure 1, a kind of antitheft antidetonation setscrew, including screw rod 1 and cap nut 2, the setscrew also include top
Head and the expansion loop 3 for being coated at screw rod 1, top is connected with screw rod one end, and top is provided with elastic locking mechanism, the band of cap nut 2
Axial direction of the dynamic expansion loop 3 along screw rod 1 moves towards top.Top passes through in elastic locking mechanism and the eyelet accomplished fluently in advance
Concave side position clamping locking, play substantially stationary effect, expansion loop gradually moves in the presence of cap nut to top afterwards
Move and then expansion loop is expanded and is reached fixation.
Preferably, top includes solid top 4 and hollow top 6, and hollow top 6 is connected by solid top 5 with screw rod 1
Connect.Screw rod 1, solid top 4, hollow top 6 are preferably structure as a whole, and are easy to process, and structural strength is high.
Elastic locking mechanism include cylinder 5 and located at it is hollow top 4 in spring 7, cylinder 5 be embedded in it is hollow top 4 in
The extruding contact of spring 7.4 preferably rectangular hollow tops, hollow top.Cylinder is preferably solid cylinder.
In order to ensure to have in the eyelet accomplished fluently the preferable effect of being locked in advance, cylinder 5 is preferably two, two posts
Body 5 is rabbeted in hollow top 4 from the both ends of hollow top 4 respectively, and the embedding incoming end of two cylinders contacts with spring.Post
The interlocking end of body is provided with the extension iron plate of anti-ejection, prevents cylinder to be ejected hollow top in the presence of built-in spring.
The present invention each part and its operation principle be：Screw rod establishes mobile road as load main support for expansion loop
Footpath, make expansion loop in the presence of cap nut along by screw rod to it is solid top gradually move so that make expansion loop expand and reach
Fixation.Cap nut：Along screw flight under manpower effect to move at perforating make screw rod away from perforating at, make expansion
Enclose to solid top motion, expanded at circular cone.Expansion loop：With solid top friction self-locking is formed in bearing.Rectangle is empty
The heart comes directly towards：It is an entirety with solid top, screw rod, in solid top afterbody.Two solid cylinders：Hollow top is embedded in respectively
The both ends of head, embedded part, which has extension iron plate, prevents cylinder to be ejected hollow top in the presence of built-in spring, passes through
Press the outboard end of solid cylinder so that it can be compressed under built-in spring effect, ejected.Will after screw eye is accomplished fluently
Screw is put into, and now spring is in compressive state, and exocuticle is parallel solid cylinder top and hollow top is easier screw
Insertion.The concave side position at the intraocular accomplished fluently in advance is being run into, by automatic spring in the presence of built-in spring, is being stuck in concave side position
Put, reach substantially stationary effect.Built-in spring：It is placed in hollow top, solid cylinder of the control in hollow top
Position.It is built-in locked before hollow top, spring, solid cylinder formation setscrew are unexpanded.(screw rod, it is solid top, it is hollow
Rectangle top is an entirety) it is inserted in expansion loop and then adds cap nut on the opposite direction top of top.Then in hollow square
Shape penetrates solid cylinder in top.The solid cylinder for penetrating rectangle hollow top is known from experience and put inside in the presence of spring prior
Concave side automatic spring in the hole accomplished fluently plays built-in fixation, is come directly towards by rectangle hollow, solid cylinder, spring, reality
The heart comes directly towards the effect to be formed and protect antitheft antidetonation.
The present invention is exemplarily described above in association with accompanying drawing.Obviously, present invention specific implementation is not by above-mentioned side
The limitation of formula.As long as employ the improvement of the various unsubstantialities of inventive concept and technical scheme of the present invention progress；Or not
It is improved, the above-mentioned design of the present invention and technical scheme are directly applied into other occasions, in protection scope of the present invention
Within.
