Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a cleat with a spring for gripping and fixing a cable, and in particular, the structure is simplified by fixing the tightening and fixing part of the lower gripping fitting to the support member. This invention relates to a cleat with a spring for fixing cables.

[Conventional technology]

An example of a conventional cable fixing cleat with a spring is shown in FIG. This cleat with a spring for fixing a cable is constructed by attaching a lower gripping metal fitting 11 to a support member 8 with a tightening bolt 4a and a nut 12a before gripping the cable, and then attaching a cable (not shown) to an upper gripping metal fitting provided with packing 3, respectively. 10 and a lower gripping metal fitting 11, and the upper gripping metal fitting 10 is integrated with the lower gripping metal fitting 11 via a spring 6 using a tightening bolt 4b, a nut 12b, and a presser washer 9. According to this, the upper gripping metal fitting 10 has a spring storage part 10a, and the lower gripping metal fitting 11 has a mounting part 11a, resulting in a complicated structure with different upper and lower parts.
There is also the disadvantage of high manufacturing costs. Furthermore, since the upper gripping metal fitting 10 is attached after the lower gripping metal fitting 11 is fixed, there is a problem that the installation work is complicated. As a solution to this problem, the configuration shown in FIG. 4 can be considered. This is the upper grip fitting 1
and the lower grip fitting 2 have the same shape, and the spring storage part 10a and the mounting part 11a.
By using the tightening bolt 4, nut 5, presser washer 9, and collar 7, it is possible to attach the upper gripping metal fitting 1 and the lower gripping metal fitting 2 to the support member 8, and tightening the upper gripping metal fitting 1. can be done at once.

[Problem that the invention attempts to solve]

However, according to the latter cleat with a spring for fixing a cable, the upper and lower gripping metal fittings 1 and 2 and the tightening bolt 4 are not fixed, but the tightening bolt 4 is simply passed through a through hole, and is not fixed to the supporting member. Since the attachment to the cleat 8 is performed by elastic engagement using the spring 6, the lower gripping metal fitting 2 cannot be firmly fixed to the support member 8, and there is a problem that the entire spring-equipped cleat will wobble.

[Means for solving problems]

The present invention has been made in view of the above, and is a cable fixing spring that fixes the lower gripping metal fitting to the tightening bolt in order to eliminate the overall wobbling by fixing the lower gripping metal fitting to the support member. cleats with cleats.

That is, the cable fixing spring-equipped cleat of the present invention has the following configuration.

(1) Pair of upper and lower gripping fittings Consists of an arcuate cable gripping part with an inner circumferential surface that is approximately the same shape as the outer peripheral surface of the cable, and flat tightening fixing parts provided at both ends of the cable gripping part. Since the upper and lower gripping fittings can have the same configuration, costs can be reduced.

(2) A pair of bolts The bolts pass through the flat support member on which the pair of gripping metal fittings for gripping the cable to be fixed are placed, and the tightening fixing portions at both ends of the pair of gripping metal fittings.

(3) a pair of springs located between the tightening fixing portions at both ends of the upper gripping fitting and locking members such as nuts and washers provided at the respective terminal ends of the pair of bolts;
Further, it is provided in a coil shape around the outer periphery of the pair of bolts. The cable tightening and fixing force can be adjusted based on this selection of elastic force and degree of compression.

(4) Fixing means The tightening fixing portions at both ends of the lower gripping fitting are fixed to the pair of bolts. This fixing means is constituted by male threads on the outer periphery of the pair of bolts and female threads on the tightening fixing portions at both ends. but,
For example, it may include a nut that is coupled to the male threads on the outer periphery of the pair of bolts and presses the tightening and fixing parts at both ends from one side, and a collar that is positioned on the opposite side of the tightening and fixing parts while resisting the pressure of the nut. It's okay to be.

[Effect]

The upper and lower gripping fittings grip the cable with arc-shaped cable gripping parts, and tighten the cable with tightening fixing parts at both ends. The upper gripping metal is biased in one direction by a coil spring located on the outer periphery of the bolt that passes through the tightening fixing part, and the biasing force is transmitted to the lower gripping metal via the cable. . The lower gripping metal fitting is fixed to the bolt by, for example, the female thread of the tightening fixing part, and is fixed to the support member via this bolt, so that when the aforementioned urging force is transmitted, it exerts a resistance against it. Occur. The cable is tightened by these two forces in opposite directions, namely the biasing force and the resisting force. As mentioned above, the upper gripping metal fitting is elastically connected to the tightening bolt, and the lower gripping metal fitting is fixedly connected to the tightening bolt, so that the cable tightened between the two is stably fixed.

〔Example〕

FIGS. 1a, b, and c show a first embodiment of the present invention, which includes an upper gripping fitting 1 comprising a cable gripping part 1a having packing 3 on the arcuate inner surface and tightening fixing parts 1b at both ends thereof; Cable grip part 2a and female thread part 2 having packing 3 on the arcuate inner surface
a lower gripping metal fitting 2 with a tightening fixing part 2b provided with c, a nut 5 and a presser washer 9 located at the end of the tightening bolt 4, and a spring provided between the presser washer 9 and the tightening fixing part 1b. 6, and a collar 7 that prevents the lower grip fitting 2 from deflecting when the tightening bolt 4 is tightened. Reference numeral 8 indicates a support member that supports the entire structure.

In the above configuration, after inserting the tightening bolt 4 into the mounting hole 8a of the support member 8, the collar 7, the lower gripping metal fitting 2, the cable (not shown), the upper gripping metal fitting 1, the spring 6, the presser washer 9, and the nut are attached. Arrange in the order of 5. The lower grip fitting 2 is fixed to the tightening bolt 4 via the female threaded portion 2c. After fixing the lower grip fitting 2, the nut 5 is tightened to press the tightening fixing portion 1b of the upper grip fitting 1 to provide appropriate elasticity via the spring 6 and to grip the cable. According to this embodiment, the lower grip fitting 2 is fixed to the tightening bolt 4 via the female threaded portion 2c,
In addition, since it is supported from below by the collar 7, deformation such as deflection or displacement can be prevented, and as a result, the entire spring-equipped cleat can be stably attached.

FIG. 2 shows a second embodiment of the invention. Portions common to the first embodiment are indicated by reference numerals, so duplicate explanations will be omitted, but the following configurations differ from the first embodiment. That is, the female screw portion 2c of the tightening fixing portion 2b of the lower gripping metal fitting 2 is omitted, and a through hole is formed through which the tightening bolt 4 can freely pass. As a result, the configurations of the upper and lower gripping fittings 1 and 2 have completely the same shape. A nut 22 is located on the upper surface of the tightening fixing part 2b with a washer 21 in between.
The tightening fixing part 2b of the lower gripping metal fitting 2 is fixed between the nut 22 and the collar 7. With this, the same effect as the first embodiment can be achieved.

[Effect of idea]

As explained above, according to the cleat with a spring for fixing cables of the present invention, the upper and lower gripping metal fittings have the same structure, and the lower gripping metal fitting is fixed to the tightening bolt, which simplifies the structure. In addition, the lower gripping fitting can be firmly fixed to the support member, and wobbling of the entire spring-equipped cleat can be eliminated.
