Detailed Description
The present utility model will be further described in detail with reference to specific embodiments in order to make the objects, technical solutions and advantages of the present utility model more apparent.
As shown in fig. 1 to 5, the novel square and round fastener provided by the utility model is composed of a first fastening plate 1, a second fastening plate 2, a locking piece 3 and the like. The first fastening plate 1 and the second fastening plate 2 have the same structure and are composed of a first connecting plate 4, a second connecting plate 5, a baffle 6 and the like. The first connecting plate 4 and the second connecting plate 5 are long strips, and one end of the first connecting plate 4 is lapped with one end of the second connecting plate 5 and is connected together through the rotation of the rotating shaft 8. A plurality of through holes 7 are formed in the first connecting plate 4 and the second connecting plate 5, in this embodiment, two rows of through holes 7 are formed in each connecting plate along the length direction, and the two rows of through holes 7 are staggered.
One end fixedly connected with baffle 6 of being connected with second connecting plate 5 on the first connecting plate 4, baffle 6 perpendicular to first connecting plate 4 sets up. When the included angle between the first connecting plate 4 and the second connecting plate 5 is 90 degrees, the second connecting plate 5 is propped against the baffle 6. The baffle 6 is used for resisting the second connecting plate 5, is convenient for directly rotate the second connecting plate 5 to the position perpendicular to the first connecting plate 4, improves installation effectiveness. A groove is formed in one surface of the baffle 6, which is attached to the second connecting plate 5, and a magnet block is fixedly connected in the groove. The magnet block is used for adsorbing the second connecting plate 5, and limiting of the second connecting plate 5 is achieved.
The storage grooves 9 are respectively formed in the end surfaces of the first connecting plate 4 and the second connecting plate 5, and when the first connecting plate 4 and the second connecting plate 5 rotate to the attached positions, the two storage grooves 9 are opposite to each other to form a complete groove body for storing the locking piece 3. The end of the storage tank 9 is provided with a chute 11, a spring 12 is arranged in the chute 11, one end of the spring 12 is fixedly connected with the end face of the chute 11, the other end of the spring 12 is fixedly connected with a push rod 13, the push rod 13 is slidably connected in the chute 11, and the end of the push rod 13 extends into the storage tank 9. The end part of the ejector rod 13 is fixedly connected with a soft cushion for protecting the end part of the ejector rod 13 and avoiding damaging the end part of the ejector rod 13 due to long-time use. The first connecting plate 4 or the second connecting plate 5 is connected with a bolt 10 in a threaded manner, and one end of the bolt 10 extends into the storage groove 9. An anti-skid groove 11 is formed in the outer wall of the other end of the bolt 10, friction is increased, and the bolt 10 is convenient to rotate.
When in a storage state, the first connecting plate 4 and the second connecting plate 5 rotate to a position where the first connecting plate 4 and the second connecting plate 5 are attached, and at the moment, the first connecting plate 4 and the storage groove 9 on the second connecting plate 5 are opposite to each other to form a cavity. The locking member 3 is put into the cavity and the locking member 3 is pushed toward the inside of the cavity, the locking member 3 pushes the ejector pin 13 toward the inside of the chute 11, and the spring 12 is compressed. Finally, the bolt 10 is fastened, so that the end part of the bolt 10 abuts against the locking piece 3, and the locking piece 3 is limited. In some embodiments, a fixing hole is formed in the surface of the locking member 3, and when the bolt 10 is fastened, the end of the bolt 10 extends into the fixing hole, so that stability of fixing the locking member 3 is enhanced. Through setting up bin 9, effectively avoid retaining member 3 to lose. Meanwhile, since the locking member 3 is fixed in the storage groove 9, the relative positions of the first connecting plate 4 and the second connecting plate 5 are fixed, so that the first connecting plate 4 and the second connecting plate 5 are prevented from rotating, and the storage is facilitated.
The using process comprises the following steps: the bolt 10 is turned to eliminate the fixing effect on the locker 3. When the end of the bolt 10 is separated from the surface of the locking piece 3, the spring 12 in a compressed state is sprung out to push the ejector rod 13 to slide towards the outside of the chute 11, so that thrust towards the outside of the storage groove 9 is applied to the locking piece 3, and the locking piece 3 is conveniently taken out. The first fastening plate 1 and the second fastening plate 2 are both opened, and the second connecting plates 5 of the two fastening plates are both rotated to the position propped against the baffle 6, namely, the included angle between the first connecting plate 4 and the second connecting plate 5 is 90 degrees. The first fastening plate 1 and the second fastening plate 2 are lapped together to form a rectangular frame structure. After the positions of the first fastening plate 1 and the second fastening plate 2 are adjusted, the locking piece 3 is inserted into the opposite through holes 7 on the first fastening plate 1 and the second fastening plate 2, so that the first locking piece 3 and the second locking piece 3 are fixed together, a formwork for manufacturing a wall column is clamped, the formwork is prevented from being deformed, and then the generation of concrete defects in the formwork is prevented.
The embodiments of the utility model are intended to embrace all such alternatives, modifications and variances which fall within the broad scope of the appended claims. Therefore, any omission, modification, equivalent replacement, improvement, etc. of the present utility model should be included in the scope of the present utility model.
