Abstract
The utility model relates to a fastener for construction, which cancels a screw thread structure in the existing fastener. A pressing rod penetrates through a hole at the outer end of a fastener body, a locking block is sheathed outside the pressing rod, the upper part of the locking block has two symmetrical slant faces with gear teeth, and the pressing rod is provided with pressing blocks corresponding to the positions of the gear teeth. When the locking block bears torques from different directions, the relative motion of the pressing block and the slant faces of the locking block enables the locking block to move up or move down, so that the fastener body is compressed or loosened. The utility model has the advantages of easy application, rapid and free dismounting, high intensity and long service life.
Description
The utility model relates to the quick fastener of a kind of self-locking, belongs to building class securing member.
Present scaffold clasp for building is to adopt screw rod, nut structure that fastener body is in addition fastening.The major defect of this structure is that screw thread easily produces corrosion, and the dead phenomenon of rust is often arranged, and makes troubles for the maintenance and the use of fastener; Simultaneously because fastener often needs a large amount of concentrating to use, helicitic texture also make the demolition, installation of fastener take a lot of work, time-consuming.
The purpose of this utility model provides the quick fastener of a kind of self-locking, has cancelled the screw threads for fastening structure of existing fastener, has solved the problems referred to above of existing fastener.
The utility model is made up of fastener body, lock dog, depression bar.Depression bar passes from the hole of fastener body outer end, and lock dog is enclosed within the outside of depression bar, and lock dog top is the inclined-plane of two symmetries, and each fixes a briquetting both sides of depression bar, and its position is corresponding with the inclined-plane on lock dog top.
The inclined-plane on lock dog top can be straight inclined-plane, also can be the curved surface inclined-plane; The inclined-plane on lock dog top can be shaped on teeth.
When using the utility model, when giving lock dog in addition during the moment of torsion of different directions, the relative motion on briquetting and inclined-plane makes the lock dog rising or moves down.When lock dog moved down, fastener body was compacted, and locking.
Lock dog and with the briquetting of its relative motion on relevant position, be designed under the reactive torque identical, and shape and size that only just can loose cunning under identical reactive torque, and their manufacturing is unlike the helicitic texture difficulty with tightening torque.
The utility model has the advantages that, under the situation of long timeliness and strong motion, can not reduce its fastening force, more can not release, and adorn, tear open fast freely, simultaneously, structure of the present utility model is than existing helicitic texture intensity height, life-span height, and can not produce rust dead phenomenon, almost service free.
Shown in the accompanying drawing embodiment of the present utility model.
Among the figure, depression bar (2) passes from the hole of fastener body (4), (5) outer end, and lock dog (1) is enclosed within the outside of depression bar (2), and lock dog (1) top is two symmetrically arranged toothed inclined-planes, and its line style both can be straight inclined-plane, also can be the curved surface inclined-plane.The both sides of depression bar (2) are fixed with two briquettings (3), and its position is corresponding with the teeth on the lock dog (1).
When by direction as shown to lock dog (1) in addition during moment of torsion, its relative motion with briquetting (3) makes it to move down, and compresses fastener body (4), (5), and locks.Lock dog in this process (1) only rotates less than half-turn.When lock dog (1) was imposed identical reactive torque, lock dog (1) rose by the relative motion of teeth and briquetting (3), and fastener body is unclamped, and reaches the dismounting purpose.
Briquetting (3) and lock dog (1) be reversing of position up and down, and briquetting becomes movement parts.
The quick fastener of self-locking is implemented easily, adorn, tear open quick and convenient, intensity height, life-span height.
Claims (4)
1, the quick fastener of a kind of self-locking, form by fastener body (4) and (5), lock dog (1), depression bar (2), it is characterized in that, depression bar (2) passes from the hole of fastener body (4), (5) outer end, lock dog (1) is enclosed within the outside of depression bar (2), lock dog (1) top is the inclined-plane of two symmetries, and each fixes a briquetting (3) both sides of depression bar (2), and its position is corresponding with the inclined-plane on lock dog (1) top.
2, the quick fastener of self-locking according to claim 1 is characterized in that the inclined-plane on lock dog (1) top is straight inclined-plane.
3, the quick fastener of self-locking according to claim 1 is characterized in that the inclined-plane on lock dog (1) top is the curved surface inclined-plane.
4,, it is characterized in that the inclined-plane on lock dog (1) top is shaped on teeth according to claim 1 or the quick fastener of 2 or 3 described self-lockings.
