Description

[Detailed Description of the Invention] The present invention relates to an improved structure of a turnbuckle, and more specifically, a floating insertion hole is provided on both sides of the turnbuckle main body frame, a large diameter portion of the base end is made larger in diameter than the floating insertion hole, Further, in the small diameter portion protruding from the tip of the large diameter portion, threaded rods having opposite threads to each other are loosely inserted into the floating insertion holes, and are screwed into the threaded portion of the small diameter portion of each threaded rod, and A locking member having an external shape such as a square or oval shape whose rotation is regulated by the inner edge of the turnbuckle main body frame is located within the main body frame,
Furthermore, by providing a locking hole in contact with the outer opening of the floating insertion hole into which the threaded portion at the tip of the large diameter portion of the threaded rod can be screwed, each threaded rod can be easily adjusted during or after use of the present turnbuckle. It is easy to move in and out of the main body frame, and when stored after use, the large diameter part of the threaded rod is screwed into the locking hole to prevent the screw threads from being crushed due to collision with other objects. , relates to a turnbuckle that can be made smaller.

Conventional turnbuckles have threaded retaining rods screwed into both sides of the main body frame, and these screw rods are used to adjust the length and tension of the object connected to both ends of the main body frame. In this case, the turnbuckle is removed from the hanging body of the object and stored in a warehouse, etc., but at this time, the turnbuckle is inserted with the threaded rod of the turnbuckle pulled out from the main body frame, or it is stacked and processed. There are many cases where the exposed screw threads of the threaded rod collide with other machine parts and become deformed or damaged, and for this reason, when reusing the turnbuckle, the body frame of the turnbuckle must be rotated to remove the threaded rod. There are problems in that it becomes difficult to screw the turnbuckle into the main body frame because the screw threads are crushed, and the turnbuckle cannot function as a turnbuckle.

The present invention was made in order to solve the problems of conventional turnbuckles as described above.
To facilitate the movement of each threaded rod into and out of a main body frame during or after use of a turnbuckle, and to maintain a suitable length and tension state with respect to an object without deforming or damaging the threaded rod. The present invention also aims to provide a turnbuckle that is easy to handle.

In order to achieve such an objective, the present invention provides floating insertion holes on both sides of the turnbuckle main body frame, has a large diameter portion at the base end that is larger in diameter than the floating insertion hole, and has a small diameter hole protruding from the tip of the large diameter portion. Threaded rods with opposite threads cut to each other are loosely inserted into the free insertion holes, and are screwed together with the threaded portion of the small diameter portion of each screw rod, and rotation is regulated by the inner edge of the turnbuckle main body frame. A locking member having an external shape such as a rectangular or elliptical shape is located within the main body frame, and a locking member that is in contact with the outer opening of the floating insertion hole and into which a threaded portion at the tip of the large diameter portion of the threaded rod can be screwed. The gist is to open a stop hole.

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 shown as 1 in the figure is provided with floating insertion holes 2 on both sides 1b of its main body frame 1a, and has a large diameter portion 3a at the base end. has a larger diameter than this floating insertion hole 2, and the large diameter portion 3a
A small diameter portion 3b protruding from the tip is provided with a threaded rod 3 which is threaded in opposite directions, leaving a part of the base end as shown in the figure.
are loosely inserted into the floating insertion holes 2, and
A locking member 4 having an outer shape such as a square or an ellipse that is screwed into the threaded portion of the small diameter portion 3b of the threaded rod 3 and whose rotation is regulated by the inner edge of the main body frame 1a is attached to the main body frame 1a.
A locking hole 5 is provided inside the main body frame 1a, and in contact with the outer opening of the floating insertion hole 2 provided on both sides 1b of the main body frame 1a, into which the threaded portion 3c at the tip of the large diameter portion 3a of the threaded rod 3 can be screwed. It has been established and configured.

That is, this turnbuckle 1 has its main body frame 1
Small diameter portions 3b of the threaded rod 3 are located on both sides 1b of the threaded rod 3.
In the floating insertion hole 2 having an inner diameter larger than the outer diameter of
The locking hole 5 is formed such that the small diameter portion 3b of the threaded rod 3 having opposite threads to each other is freely inserted and removed, and the large diameter portion 3a of the threaded rod 3 is opened in contact with the outer opening of the floating insertion hole 2. It can be screwed into place for temporary fixation.

Further, the threaded portion of the small diameter portion 3b of the threaded rod 3 is screwed together within the main body frame 1a by a locking member 4 whose rotation is regulated by the inner edge of the main body frame 1a, for example, a nut as shown. There is.

As shown in FIG. 3, which is an enlarged view of part A in FIG. The large diameter of the threaded rod 3 is made into a locking hole 5 formed by cutting a threaded portion 3c of the large diameter portion 3a of the threaded rod 3, that is, a threaded portion 5a that can be screwed into the tip of the large diameter portion 3a. The screw portion 3c of the portion 3a is screwed together to temporarily fix the portion.

Here, the threaded rod 3 is inserted from both sides into the floating insertion hole 2 of the main body frame 1a with the small diameter part 3b in a floating state, and after use, the large diameter part 3a is inserted into the main body frame 1a as shown in FIG. 1a into the locking holes 5 formed on both sides 1b, screw the threaded portion 3c at the tip of the large diameter portion 3a into the locking hole 5, temporarily fix the threaded rod 3, and remove the screw from the main body frame 1a. This is to prevent the rod 3 from moving in or out.

In addition, the locking member 4 is adapted to operate when the turnbuckle 1 is in use, for example, by connecting both base ends of the threaded rod 3 and the object to be in a non-rotating state.
When adjusting the length, tension, etc. between the objects by rotating the main body frame 1a, as the main body frame 1a rotates, the threaded rod 3 is pulled out to the outside of the main body frame 1a, or the main body frame 1
a Used as a member for pulling back inward.

Here, since the threaded rods 3 are temporarily fixed by screwing as described above, the tip surfaces of the threaded rods 3 are made to be in a non-contact state within the main body frame 1a, but as shown in the figure, temporarily Even in the fixed state, the length may be such that the respective tip surfaces do not come into contact with each other within the main body frame 1a.

In this way, when the end surfaces of the threaded rods 3 are brought into a non-contact state within the main body frame 1a, for example, when adjusting the tension of the object using long and short threaded rods 3 having different lengths, During or after use, the threaded rod 3 can be quickly pulled out from within the main body frame 1a or easily pulled back into the main body frame 1a.

Therefore, when using this turnbuckle 1, objects are connected to each other through connectors (not shown) attached to the proximal ends of each threaded rod 3 protruding from the main body frame 1a in the state shown in FIG. If the threaded rod 3 is in a non-rotating state in which it does not rotate together with the main body frame 1a, and then the main body frame 1a is rotated, the locking member 4 in the main body frame 1a will rotate together depending on the direction of rotation. Then, adjust the position of the threaded rod 3 inward and outward with respect to the main body frame 1a, adjust the strength of its installation, and when not in use, remove the object from the base end of the threaded rod 3. is in a free state, so that the free insertion hole 2 of the main body frame 1a and the large diameter portion 3 of the threaded rod 3
If the threaded rod 3 is pushed into the main body frame 1a using the relationship a, the small diameter portion 3 of the threaded rod 3 will be inserted into the floating insertion hole 2.
b is loosely inserted and housed in the main body frame 1a, and at the same time its large diameter part 3a is inserted and locked into the locking hole 5 in the main body frame 1a, and then the large diameter part 3a is rotated. Then, the threaded portion 3c of the large diameter portion 3a is screwed into the locking hole 5, and the threaded rod 3 is temporarily fixed to the main body frame 1a.
It will be in a state where it will not come out carelessly and will be in an internal state.

Note that the threaded part 5a for screwing the large diameter part 3a of the threaded rod 3 into the locking hole 5 is only for temporarily fixing the threaded rod 3, so it should be inserted in the right direction for easy operation. It is preferable to cut it into strips.

As described above, the turnbuckle of the present invention has floating insertion holes on both sides of the turnbuckle body frame,
The proximal large diameter portion is made larger in diameter than the floating insertion hole, and the small diameter portion protruding from the tip of the large diameter portion is threaded with opposite threads to each other, and threaded rods are loosely inserted into the floating insertion hole, respectively. Screw into the threaded part of the small diameter part of each threaded rod,
A locking member having a rectangular, oval, or other external shape whose rotation is regulated by the inner edge of the turnbuckle main body frame is located within the main body frame, and further includes a locking member having an external shape of the turnbuckle main body frame, and is in contact with an outer opening of the floating insertion hole to lock the threaded rod. Since there is a locking hole into which the threaded part can be screwed at the tip of the large diameter part, the threaded rod can be freely moved outward or inward in the axial direction of the main body frame, making it easy to handle. In particular, after using the turnbuckle, the large diameter part of each threaded rod can be stored by simply pushing it into the main body frame, and the large diameter part of the threaded rod can be screwed into the locking hole made in the main body frame. If temporarily fixed, the turnbuckles will be stored in a warehouse etc. in this fixed state, and during storage work or storage, the turnbuckles may collide with each other or with other machinery and equipment, resulting in the screw threads of the threaded rods becoming crushed and becoming unusable. No more getting used to.

In addition, since floating insertion holes and locking holes can be easily formed in the main body frame using casting methods, mass production is not only possible, but the package is also compact because it is compact when stored. It is also convenient for handling, transportation, and storage.
