Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is a multiple type tightening for tightly holding two tightening objects such as a split type protective sleeve of a communication cable at a plurality of consecutive places. It relates to the device.

[Prior Art] JP-B-56-46442 and JP-A-59-7427
The conventional tightening device disclosed in Japanese Unexamined Patent Publication No. 6 has a hooking link having a hooking part provided at a tip end thereof to be hooked on an engaging part of one tightening target, and is fixed to the other tightening target. The mounting base and the operating lever, the base end of which is pivotally attached to the bearing plate of the mounting base by the first pivot, and the intermediate portion of which is pivotally attached to the base end of the hooking link by the second pivot, are two tightening levers. When the objects to be attached are fastened to each other, the second pivot is located on the side of the other object to be fastened with respect to the straight line connecting the hook portion and the first pivot. [Problems to be Solved by the Invention] In this conventional device, since the hooking link and the operating lever are connected to each other through the first pivot and the second pivot with respect to the mounting substrate fixed to the object to be fastened, nothing is done. When the tightening is released and the object to be tightened is removed for the processing work, all the components of the tightening device remain attached to the object to be tightened. Therefore, when the object to be tightened falls from a high place to the floor or is thrown violently, or when other equipment collides with the object placed on the floor, the tightening device is distorted or deformed. May be damaged.

In addition, when the body and lid of a transport container, which is subject to severe wear, are to be tightened, such a fixed-type tightening device must also discard the tightening device that is still usable when the transport container is discarded. There is a lot of waste because you don't get

Therefore, an object of the present invention is to provide a non-fixed type in which the entire device can be detached from the tightening target when the tightening of the tightening target is released, and the tightening can be performed at a plurality of consecutive positions. It is to provide a multiple tightening device.

[Means for Solving the Problems] The non-fixed multiple clamping device according to the present invention will be described below with reference to the reference numerals in the accompanying drawings. 4 are arranged in parallel corresponding to the pulling rods 4 and the hooking rods 3 which are inserted through the respective tip portions 21 of 4 and hooked to the plurality of engaging portions 2 provided in parallel with the tightening target 1. The plurality of tensioning links 8 and the tip end portions 22 of the respective tensioning links 8 are individually inserted, and separately and separately pressed against the plurality of engaging portions 6 provided in parallel with the tightening target 5. It is composed of a pushing rod 7, and the base end 9 of the corresponding pulling link 4 and the base end 10 of the corresponding tensioning link 8 are individually connected by a pivot 11 to connect the tightening target 1 and the tightening target 5 to each other. When tightened, the pivot 11 is located on the tightening target 5 side with respect to the straight line connecting the hooking rod 3 and the pushing rod 7. It is a thing.

[Operation] A single hooking rod 3 is attached to a plurality of engaging portions 2 and 2 of the tightening target 1.
And press each of the pushing rods 7 of the plurality of tension links 8 individually against each of the plurality of engaging portions 6 of the tightening target 5, and then tighten each of the plurality of pulling links 4. When pushed individually toward the objects 1 and 5, each pulling link 4 rotates about the engaging portion 2, while each tension link 8 rotates about the engaging portion 6 and the pivot 11 The pulling links 4 and the pulling links 8 which are connected with each other come closer to the tightening objects 1 and 5 side as a unit.

When the pivot 11 is on the front side with respect to the straight line connecting the rotation center of the hooking rod 3 supported by the engaging portion 2 and the rotation center of the pushing rod 7 supported by the engaging portion 6, packing between the tightening objects is performed. The repulsive force caused by the elasticity of the member and the tightening object itself or the elasticity of each pulling link and the pulling link itself resists the rotation operation of each pulling link 4 and the pulling link 8.

At the moment when each pivot 11 crosses the straight line connecting the center of rotation of the hooking rod 3 and the center of rotation of the pushing rod 7 toward the object 5 to be tightened, the repulsive force pushes the pulling link 4 and the tensioning link 8 in the moving direction. The pulling link 4 and the tension link 8 are swung with vigorous force to convert the pulling link 4 into a proximal end portion 9 of each pulling link 4.
Collides with the surface of the tightening target 5.

This completes the closing tightening of the tightening objects 1 and 5, but the repulsive force acts as a rotational moment in the direction of pressing the base end 9 of each pulling link 4 against the surface of the tightening object 5. Therefore, the tightened state is accurately maintained, and the tightening is not unintentionally released due to vibration or shock.

The base end 9 of each pulling link 4 is resisted against this rotation moment.
When pulling up, the pulling link 4 reversely rotates about the hooking rod 3, and in conjunction with this, each tensioning link 8 reversely rotates about the pressing rod 7. At the moment when each pivot 11 crosses the straight line connecting the center of rotation of the hook bar 3 and the center of rotation of the pushing bar 7 to the front side,
The compressive force acting on each of the tension links 8 and the tensile force acting on each of the tension links 4 disappear.

Therefore, the engaging engagement between each engaging portion 2 and the engaging rod 3 and the engaging engagement between each engaging portion 6 and the pressing rod 7 are immediately released, and the engaging rod 3 is disengaged from the engaging portion 2 while being pressed. By separating the hitting rod 7 from the engaging portion 6, the pulling links 4 and the tensioning links 8 can be detached from the tightening objects 1 and 5.

[Embodiment] In the illustrated embodiment, the tightening objects 1 and 5 are split-type protective sleeves that cover the connection portion of the communication cable, and the packing member 12 is attached to the joint end surface. The engagement part 2 formed of a strip-shaped ridge is integrally molded on the surface of the joint end of the object 1 to be tightened.
