Description
Technical Field
The utility model relates to a ripple spring bolt self-lock device belongs to building pile technical field.
Background
The prefabricated building refers to a building assembled on a construction site by using prefabricated components. Because the assembly type building is high in building speed and low in production cost, the assembly type building can be rapidly popularized all over the world, everyone can build a house by DIY design, the wall can be repeatedly disassembled, and construction waste caused by wall dismantling can be avoided due to repeated utilization.
The current locking device shell is the punching press formula cuboid, and inside two springs of disconnected nut bilateral symmetry arrangement have the guide rail of fixation nut direction on the shell, and disconnected nut both ends spring lasts and gives a thrust of nut, and after tubular pile end quick-operation joint's many screw rods impacted fast and got into the nut, both ends spring can promote nut locking screw, and the atress mode is the both sides atress. The existing product has the following problems: 1. the manufacturing process is complex; 2. the concentricity precision is poor when the bolt and the nut are in impact fit, and the phenomenon that the quick connector at the end of the tubular pile is scrapped is likely to occur; 3. the number of parts is large, and the assembly is not easy; 4. the whole piece has larger volume and higher cost.
Therefore, it is a problem to be solved urgently to design a self-locking device with simple preparation process, low cost, high precision and convenient assembly.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a ripple spring bolt self-lock device, its design scientific and reasonable, preparation simple process, with low costs, the precision is high, and convenient assembling does benefit to the industrialization and uses.
The utility model discloses a ripple spring bolt self-locking device, including shell, ripple spring, disconnected nut and twin-screw bolt are equipped with in proper order in the shell, disconnected nut is in the cohesion state under the effect of ripple spring; the lower end of the double-screw bolt and the inner side of the disconnected nut are both provided with single-sided inclined threads; the lower end of the double-screw bolt is matched with the break-away nut.
The shell is circular.
The housing, the corrugated spring, the breakaway nut, and the twin screw bolt are concentric.
Preferably, the pitch of the single-sided oblique thread is 2.5-3.5 mm.
Preferably, the upper end of the twin screw bolt is provided with conventional threads.
Preferably, the housing and the corrugated spring are in transition fit.
Preferably, the corrugated spring and the break-away nut are in transition fit.
The break-away nut is composed of two semicircular rings.
In the utility model, the matching between the shell and the ripple spring, and between the ripple spring and the break-away nut are transition matching, and the break-away nut is in a closed state when not stressed; the ripple spring is in an unexcited state when not extruded by external force; when the double-screw bolt with the single-sided inclined threads enters the disconnected nut in a single direction under the gravity impact, the disconnected nut is changed from a closed state to a symmetrical separated state (the distance is about 1-2.5mm), and at the moment, the corrugated spring is extruded for 360 degrees, so that the lasting elasticity is released, and the disconnected nut is always in a locked state.
Compared with the prior art, the utility model discloses following beneficial effect has:
(1) the shell of the utility model is round, the previous stamping link is saved, the existing general material is adopted for manufacturing, and the preparation process is simple;
(2) the utility model is provided with the annular ripple spring, so that the stress mode is 360 degrees and the stress is uniform, and the concentricity problem of the bolt and the nut during impact is effectively solved;
(3) the utility model changes the original five parts into four parts, the volume and the weight of the whole part are reduced compared with the original product, and the cost is greatly reduced;
(4) the utility model adopts concentric circle design, reduces parts and greatly reduces failure rate;
(5) the utility model discloses a transition fit does not have the pretightning force mode, has improved assembly efficiency by a wide margin.

Detailed Description
The present invention is further described with reference to the following examples, which are not intended to limit the practice of the invention.
Example 1
As shown in fig. 1-8, the corrugated spring bolt self-locking device of the present invention comprises a housing 1, a corrugated spring 2, a break-away nut 3 and a twin-screw bolt 4, wherein the corrugated spring 2, the break-away nut 3 and the twin-screw bolt 4 are sequentially arranged in the housing 1, and the break-away nut 3 is in a clasping state under the action of the corrugated spring 2; the lower end of the double-screw bolt 4 and the inner side of the disconnected nut 3 are both provided with single-sided inclined threads 5; the lower end of the double-screw bolt 4 is matched with the break-away nut 3.
The housing 1 is circular.
The shell 1, the corrugated spring 2, the break-away nut 3 and the twin-screw bolt 4 are concentric.
The thread pitch of the single-sided inclined threads 5 is 3 mm.
The upper end of the double-screw bolt 4 is provided with conventional threads.
The shell 1 and the corrugated spring 2 are in transition fit; the corrugated spring 2 and the break-type nut 3 are in transition fit.
The break-away nut 3 consists of two semicircular rings.
The existing tubular pile end quick joint consists of two carbon steel flanges, and the two flanges are connected by 12 sets of corrugated spring bolt self-locking devices. 12 screw holes are concentrically and uniformly distributed on the end surface of the upper flange and are connected with the double-screw bolt 4 in the utility model; lower flange will the utility model provides a break-away nut 3 and ripple spring 2 and shell 1 assemble the postweld at the flange terminal surface, leave 12 thru holes that are greater than the 4 diameters of twin-screw bolt on the flange, the twin-screw bolt 4 of being convenient for sees through lower flange and the cooperation of break-away nut 3, and the screw that the distribution position and last flange distribute is concentric. Under the action of gravity, the double-screw bolt 4 with the single-sided inclined threads 5 distributed on the concentric circle of the upper flange overcomes the elasticity of the corrugated spring 2360 degrees and rushes into the disconnected nut 3, the disconnected nut 3 is firmly clamped by the reaction force of the corrugated spring 2, so that the inner thread of the disconnected nut 3 is completely matched with the outer thread of the double-screw bolt 4, and the quick connection of the tubular pile is completed.
