Description

[Detailed description of the invention] The present invention relates to an improved structure of a turnbuckle, and more specifically, a threaded rod is loosely inserted into the loose insertion hole provided on both sides of the turnbuckle main body frame, and rotated by the inner edge of the main body frame. By screwing together a locking member that regulates the rotation of the turnbuckle with a threaded rod inside the main body, and providing a fixing means for temporarily fixing the threaded rod between the main body frames, after using this turnbuckle, each turnbuckle can be inserted into the main body frame. It does not require the screwing operation of a threaded rod, and can be installed simply by inserting it, and it is also small enough that it can be temporarily fixed so that the screw thread will not be crushed by hitting other objects during storage or handling after use. Regarding the turnbuckle that made it possible to

Conventionally, turnbuckles have threaded retaining rods inserted from both ends of the main body, and these screw rods are used to adjust the length and tension of objects connected to both external ends. In this case, the turnbuckles are removed from the hanging body of the object and stored in a warehouse, etc., but in many cases, the turnbuckles are inserted or stacked with the threaded rod of the turnbuckles pulled out from the main body. Because it is processed,
Problems such as the exposed screw threads of the threaded rod colliding with other machine parts and becoming deformed or damaged often occur, so when reusing the turnbuckle body frame, it is necessary to rotate the turnbuckle main body frame and attach the threaded rod. It was difficult to screw into the main body frame because the threads were crushed, and there were drawbacks such as the inability to function as a turnbuckle.

The present invention was made in order to eliminate the drawbacks of the conventional turnbuckles mentioned above, and it is not affected by the deformation or damage of the threaded part when the turnbuckle is used, and has a length suitable for the object. The purpose is to provide a turnbuckle that maintains tension and is easy to handle and store after use. is provided, and threaded rods with the same outer diameter and opposite threads are loosely inserted into this floating insertion hole, and
A male thread with an outer diameter smaller than that of the threaded rod is provided protruding from the end edge of one threaded rod that faces the other, and whose axes substantially coincide with each other, and the male thread is screwed onto the end edge of the other threaded rod. A rectangular shape in which a female thread that can be inserted is made into a recess so that it substantially coincides with the axis of the threaded rod so that they can be fixed to each other, and which is screwed into the threaded rod and whose rotation is regulated by the inner edge of the main body.
The turnbuckle is characterized in that a locking member having an external shape such as an oval shape is located within the main body.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows how the turnbuckle according to the present invention is used. The turnbuckle main body, for example a frame-type main body 1, has ends 1 on both sides of the frame 1a.
Floating charging holes 2, 2 having the same inner diameter are provided oppositely in b, 1b, and are located within the frame of the main body 1.
A locking member 4 having an outer shape such as a rectangular or oval shape whose rotation is regulated by the inner edge of a is screwed together, and threaded rods 3 having the same outer diameter and having opposite threads are inserted into the floating charging hole 2. It is configured by loosely inserting each into.

Further, a male thread 5 having an outer diameter smaller than that of the threaded rod 3 is provided protruding from the end edge of one threaded rod 3 facing the other, and the axis of the threaded rod 3 is substantially coincident with that of the other threaded rod 3.
A female screw 6 into which the male screw 5 can be screwed is provided in the end edge of the screw rod 3 so as to substantially coincide with the axis of the screw rod 3, so that one screw rod 3 and the other screw rod 3 can be fixed to each other. It is said that

That is, the illustrated frame-type turnbuckle main body 1 is provided with a floating charging hole 2 located at an end 1b of the frame 1a and having an inner diameter larger than the outer diameter of the threaded rod 3. A threaded rod 3 with opposite threads cut to each other is removably inserted into the threaded rod 3, and a rectangular or oval shape, etc., which is located within the main body frame 1a and whose rotation is regulated by the inner edge of the main body frame 1a, is inserted into the threaded rod 3. A locking member 4, for example, a nut is screwed into the locking member 4 as shown in the figure.

This locking member 4 operates when the turnbuckle is used, for example, by connecting both ends of the threaded rod 3 and the object to be in a non-rotating state, and then rotating the frame 1a to move the object between the objects. It is used as a member for pulling out the threaded rod 3 toward the outside or pulling it back toward the inside of the main body 1 as the turnbuckle main body frame 1a rotates when adjusting the length, tension, etc.

Further, the threaded rod 3 is inserted into the floating insertion hole 2 of the main body 1 from both sides in a floating state, and after use, the threaded rod 3 is inserted from the turnbuckle frame 1a between the threaded rods 3 as shown in FIG. Temporary fixing means S is provided to prevent movement in and out.

That is, a male thread 5 is provided protrudingly on one end edge of the threaded rod 3, and a female thread 6 into which the male thread 5 can be screwed is provided recessedly on the other end edge of the threaded rod 3. are screwed together and temporarily fixed.

Therefore, when using the turnbuckle of the present invention, each threaded rod 3 is
The threaded rod 3 connects the object to the tip of the frame 1a.
If the turnbuckle frame 1a is rotated in a non-rotating state in which it does not rotate together with the body 1, the locking members 4 in the frame 1a will rotate in accordance with the direction of rotation, causing the threaded rod to move in and out of the body 1. Adjust the position and strength of the installation condition, and when not in use, tighten the threaded rod 3.
If the object at the tip is removed, the threaded rod 3 becomes free, so using the relationship between the size of the floating insertion hole 2 of the main body 1 and the threaded rod 3, insert the threaded rod 3 into the frame 1a.
When pushed in, the threaded rod 3 is loosely inserted into the floating insertion hole 2 and accommodated in the frame body 1a, and then by using the temporary fixing means S according to the above embodiment, the threaded rod 3 is inserted into the frame body 1a. It will not come out carelessly from inside 1a and will be in an internal state.

As described above, the turnbuckle of the present invention has floating loading holes on both sides of the main body frame, and threaded rods with opposite threads cut to each other are inserted into the floating loading holes in a floating state, and one end of the screw rod is inserted into the floating loading holes. A male screw is provided protrudingly on the edge, and a female screw into which the male screw can be screwed is provided recessed in the end edge of the other threaded rod to enable fixation, and the screw rod is screwed together with the inner edge of the main body. Since the locking member that restricts rotation is located inside the main body, the threaded rods can freely move outside or inside the turnbuckle main body in the axial direction.Especially, after using the turnbuckle, each threaded rod can be simply moved into the main body. It can be stored inside by simply pushing it inward, and if a temporary fixing means is used, this storage state will be fixed and even if it is stored in a crowded place such as a warehouse, the turnbuckles will not fit together during the storage operation.
Even if it collides with other mechanical devices, etc., unlike conventional threaded rods that protrude from the turnbuckle body, the screw threads will not be crushed and the turnbuckle will become unusable. Since the package is kept in a compact state, the package is small and convenient for transportation and storage. Moreover, the turnbuckle is simple in structure, easy to handle, and trouble-free, and can be temporarily fixed.
