Description

[Detailed Description of the Invention] [Industrial field of application] The present invention can be used as an oil filter wrench,
The present invention relates to a rotating tightening device that can be used as a cap driver of a container and can be used for multiple purposes such as a support tool such as a pile.

[Conventional technology]

The conventional product uses a chain as the tightening member, so it has the drawback of scratching the object to be tightened, and the chain does not fit exactly on the object to be tightened, so it can be slipped and tightened securely. There were also no drawbacks.

In addition, the structure is complicated, resulting in a high cost product.

[Problems to be solved by the device]

The present invention solves the above-mentioned drawbacks, and since an elastic tightening band is used for the tightening member, the adhesion is good, and since it does not slip, the tightening rotation is surely performed and the structure is simple, so that the manufacturing is easy. Therefore, it is a technical subject to provide a low-priced rotary fastening device.

[Means for Solving the Problems]

 The gist of the present invention will be described with reference to the accompanying drawings.

The base end portions of the elastic tightening band 2 are fixed to each other by a stopper 7, and the base end of the elastic tightening band 2 fixed by the stopper 7 is slidably disposed in the grip cylinder 1. The locking ring portion of the elastic tightening band 2 can be pulled out from the tip outlet portion 1a of the gripping cylinder 1, and the diameter of the locking ring portion of the elastic tightening band 2 can be freely narrowed or narrowed according to the degree of pulling out. The elastic tightening band 2 is connected to the distal end of the towing cord 3 so that the proximal end of the towing cord 3 can be freely pulled out from the proximal end outlet 1b of the gripping cylinder 1. A through hole 11 which is provided and through which the tow cord 3 can be freely pulled out through the proximal end outlet portion 1b, and a locking hole 10 which communicates with the through hole 11 and locks the tow cord 3 so as not to be pulled out. A string fixing mechanism a for fixing the tow string 3 formed and pulled out to a predetermined length is provided, and the tow string 3 is arranged in the through hole 11 to draw the tow string 3
The elastic tightening band 2 is pulled out and the pulling cord 3 is moved to be arranged in the locking hole 10 communicating with the through hole 11 so that the pulling string 3 cannot be pulled out and the elastic tightening band 2 is pulled out. It relates to a rotary tightening device characterized in that the diameter of the engaging ring portion is held at a predetermined size.

[Action]

As shown in FIG. 3, while the elastic tightening band 2 is largely pulled out, the engaging ring portion of the elastic tightening band 2 is fitted on the object to be tightened 5 (for example, an oil filter cap), and then gripped. While projecting through the through hole 11 of the proximal end outlet 1b of the gripping cylinder 1 to pull the tow string 3 to temporarily tighten the to-be-tightened object 5, the tow string 3 is moved to engage from the through hole 11. It is arranged in the stop hole 10 and locked and fixed by this string fixing mechanism a.

In this state, when the grip cylinder 1 is gripped and pivotally moved in the direction of the arrow, the base of the engaging ring portion of the elastic tightening band 2 protruding from the tip outlet 1a is pressed from the outside by the tightening enhancement protrusion 4. The elastic tightening band 2 is pressed inward so that the object to be tightened 5
Since it is tightened, the object to be tightened 5 can be loosened by rotating the gripping cylinder 1 in the direction of the arrow in this state.

On the contrary, when the grip tube 1 is rotated in the opposite direction, the object to be fastened 5 can be fastened.

〔Example〕

The elastic tightening band 2 is shown as a rubber band, and has a groove 6 formed in the lengthwise direction of the inner surface thereof to improve adhesion.

The proximal end portions 2a of the elastic tightening band 2 are superposed on each other, the superposed portion is stopped by a stopper 7, and the end portion of a chain 8 which is an example of the tow string 3 is fixedly connected to the stopper 7. .

The string fixing mechanism a is provided with a closing lid 9 at the lower end portion of the gripping cylinder 1 made of a metal pipe, a through hole 11 with a locking hole 10 is bored in the closing lid 9, and the chain 8 is pulled out from the through hole 11. Locking hole 10
The drawing shows a case where the pull-out size of the elastic tightening band 2 is adjusted by being locked to the.

The tow string 3 is not limited to the chain 8 and may be a wire, a vinyl rope, or the like.

The tightening enhancement projection 4 uses a metal pipe.

[Effect of device]

Since the present invention is constructed as described above, the elastic tightening band 2 is provided.
To the object to be tightened 5, pull the tow string 3 to squeeze the elastic tightening band 2, fix the tow string 3 to the gripping cylinder 1 by the string fixing mechanism a, and then grasp the gripping cylinder 1. When held and pivotally moved, the tightening protrusion 4 presses the base end of the elastic tightening band 2 projecting from the distal end outlet portion 1a of the gripping cylinder 1 from the outside, so that the elastic tightening band 2 tightens the object 5 is strongly tightened, the elastic tightening band 2 does not slip, and the object 5 to be tightened can be securely rotated and tightened.

Further, the elastic tightening band 2 is brought into close contact with the object to be tightened 5 so that reliable rotational tightening can be performed.

In addition, it can be used with confidence without being scratched by friction.

As for the structure, materials such as rubber, leather, and cloth can be used for the fastening members, and the material can be saved. Also, the structure is simple and the manufacturing is easy. It has excellent practical effects.

In addition, according to the present invention, when pulling the locking ring portion of the elastic tightening band 2 to temporarily tighten the elastic tightening band 2 to the object to be tightened 5, the base end of the elastic tightening band 2 is The pulling cord 3 disposed in the inserted holding cylinder 1 and protruding from the proximal end outlet 1b of the holding cylinder 1 may be pulled. Therefore, hold the holding cylinder 1 with one hand,
Since the pulling cord 3 is pulled by the other hand in the lengthwise direction of the holding cylinder 1, it is easy to handle and the pulling cord 3 can be pulled with a strong force, and this temporary tightening operation becomes extremely good.

Moreover, the string fixing mechanism a is a through hole 11 through which the tow string 3 can be pulled out freely through the base end withdrawal portion 1b, and a member which communicates with the through hole 11 and locks the tow string 3 so that it cannot be pulled out. The pulling cord 3 which forms the stop hole 10 is fixed to a predetermined length to fix the pulling cord 3 to a predetermined length, and the pulling cord 3 is arranged in the through hole 11 to pull out the pulling cord 3 and pull out the elastic tightening band 2. In addition, the pulling cord 3 is moved to be arranged in the locking hole 10 communicating with the through hole 11 so that the pulling string 3 cannot be pulled out, and the diameter of the locking ring portion of the elastic tightening band 2 is set to a predetermined value. Since the tow cord 3 is configured to be held in a size, it is sufficient to pull the tow cord 3 and temporarily tighten it, and then simply move the position of the tow cord 3 from the through hole 11 to the locking hole 10.

Therefore, while pulling the pulling cord 3 while holding the gripping cylinder 1, the pulling cord 3 is moved as it is, locked in the locking hole 10 and fixed, and the gripping barrel 1 is rotated and moved as it is. By doing so, the object to be tightened 5 can be tightened and rotated, so that a rotating operation can be performed from temporary fixing and fixing by a series of operations without changing the holding, and the tightening and rotating device has extremely excellent operability.

The product of the present invention can be used not only for turning and tightening but also as a holding tool when driving a pile.
