Description

A kind of C shape wire clamp

Technical field

The utility model relates to a kind of wire clamp, and more particularly, it relates to a kind of C shape wire clamp.

Background technology

At present, wire clamp generally applies in the middle of wire connection, conveniently power, need that wire clamp is installed in main circuit and carry out command current, wire clamp is used in the middle of high altitude wire connection mostly, all need workman to climb up with wire clamp from electric pole to install, and in installation process, need wire clamp clamping circuit could be carried out being connected.

In actual mechanical process, when using wire clamp to clamp, often because be placed in outside, wind rain shines, easy generation loosens, thus cause coming off of wire clamp, and when mounted, wire clamp when clamping cable because need by by bolt-locking, but in force process, operating personnel are difficult to wire clamp to lock, be on the one hand because in work high above the ground, force is inconvenient, if be on the other hand because overexertion, easily cause ribbon damage, which results in wire clamp easily relax in use and come off, thus make its useful life shorter, therefore be necessary that proposing a kind of better scheme solves these problems.

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of handled easily, can not loosens, clamping effect is good and the C shape wire clamp of long service life.

For achieving the above object, the utility model provides following technical scheme: a kind of C shape wire clamp, comprise upper clamp and lower clamp, cooperatively interact between described upper clamp and lower clamp the cavity offered for wearing for cable, described upper clamp and lower clamp pass through bolt-locking, the head of described bolt is also fixedly connected with rotation erection joint, the one-body molded thin-walled had for locking rear fracture between described rotation erection joint and bolt.

As preferably, described rotation mounting head is that hexagon is arranged.

As preferably, described bolt and upper clamp, between described bolt and lower clamp, all improved mat is installed.

As preferably, be provided with anti-release member between described bolt and upper clamp, described anti-release member becomes circular setting and anti-release member offers breach, the two ends of described anti-release member in indentation, there in setting of staggering.

As preferably, the chamber wall of described cavity is all arranged to zigzag.

As preferably, be also provided with the fixed head for fitting with upper clamp between described bolt and upper clamp, the back side of described fixed head and upper clamp is suitable.

Compared with prior art the utility model has following advantage: have rotation erection joint by the head increase at bolt, one-body molded between rotation erection joint and bolt have thin-walled, when cable is put in lock in the cavity between upper clamp and lower clamp time, screwing bolts is carried out by clamping rotation erection joint, rotate until the thin-walled rotated between erection joint and bolt ruptures, now be locking state, this makes it possible to clamp cable by wire clamp very easily, and coupling mechanism force is large like this, be not easy to depart from, can not produce loosening, this makes it possible to make C shape wire clamp reach handled easily, can not loosen, good and the object of long service life of clamping effect.

Accompanying drawing explanation

Fig. 1 is the structural representation of embodiment.

In figure: 1, upper clamp; 2, lower clamp; 3, cavity; 4, bolt; 5, erection joint is rotated; 6, thin-walled; 7, anti-release member; 8, breach; 9, improved mat; 10, fixed head.

Embodiment

With reference to Fig. 1, a kind of C shape of the utility model wire clamp is described further.

As shown in Figure 1, upper clamp and lower clamp offer through hole and wear for bolt, and bolts and nuts coordinate upper clamp and lower clamp clamping, the two sides that upper clamp is relative with lower clamp is that cambered surface is arranged, be oppositely arranged formation cavity to wear for cable, rotation erection joint is also fixedly connected with at the head of bolt, one-body molded between rotation erection joint and bolt have thin-walled, the thickness of thin-walled is at about 0.2mm, clamp rotation erection joint when use fixture like this to lock bolt, when rotating to bolt and can not rotating again, namely the state of locking is reached, and thin-walled can be broken when now exerting a force again, namely rotate erection joint and depart from bolt, this makes it possible to clamping screw, and do not need to worry whether coupling mechanism force enough reaches, thus ensure that the clamping force of wire clamp can not produce loosening.

Certainly comparatively preferably between bolt and upper wire clamp, all increase between bolt and drop wire clip and have improved mat, relax for preventing bolt further, and also increase between bolt and upper wire clamp and have anti-release member, anti-release member becomes annular arrange and offer opening in its side, at the two ends of opening part in setting of staggering, such bolt is after applying thrust to it, difference in height is there is between the two ends of anti-release member, the two ends of such anti-release member are formed with the power of pushing against respectively to bolt and upper clamp, thus enable bolt by stretching, this makes it possible to reach the function preventing bolt from relaxing, in order to shake when ensureing bolt-locking, the upper surface laminating of upper clamp is provided with fixed head, the upper surface of fixed head is a plane, the radian at the back side of lower surface and upper clamp is suitable, during such locking, fixed head can be firm work good with upper clamp, can push against with the upper plane of fixed head when bolt-locking like this, contact area is large, frictional force is large, stable connection, certainly more preferably the chamber wall of cavity is arranged to zigzag, is to better cable be clamped like this, thus realizes the linking of better cable, below just reach make C shape wire clamp reach handled easily, can not loosen, the good and object of long service life of clamping effect.

The above is only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
