Description

This invention relates to devices for fastening flexible elements, such as wires, cables, wires, cables, ropes, etc.

A similar device is known, comprising a housing having a longitudinal recess with a clamping element located therein, for example, a drop-shaped form and a compression spring, and its channel formed in the wall, which communicates with the POST of the longitudinal longitudinal recess.

Such a device is not sufficiently reliable.

To increase the reliability of the device in operation, it is equipped with a control element mounted on the housing, connected through a slot made in the housing wall, with a clamping element. In this case, the channel forms an acute angle with the longitudinal notch, and the clamping element is connected to the pressure spring with the possibility of tilting.

FIG. 1 shows the proposed device, a general view; in fig. 2 and 3 - the same, cuts; in fig. 4 - device equipped with a karabiner hook; in fig. 5 shows an embodiment of the device; in fig. 6 and 7 - the same, cuts; in fig. 8 shows a device with several double-sided clamping devices arranged in parallel, top view; in fig. 9 - then

a longitudinal section; in fig. 10 —warpang execution of the device (1e of the wire is introduced laterally); in fig. 11 - the same, longitudinal incision.

On the body / screwed on the tip 2, to which the hook 3 or carabiner hook 4 is attached. In the body / a longitudinal notch 5 is made with a tapered section 6 at the end 7 of the body facing the connection of the fixed wire, the axis of which is eccentrically offset from the axis of the body .

iB parts of the body with a thicker wall; A channel 8 is made, the axis of which forms an acute angle with the axis of the longitudinal notch 5, which is infrequently from 15 to 20 °.

In the cavity formed by the intersection of the longitudinal notch 5 with the channel 8. A clamping element 9 is positioned, the pigment portion W adjacent to the walls of the narrowed portion 6 of the longitudinal notch 5 from the end of the housing 7 and rounded. On the opposite side, the clamping element has a section P, the diameter of which decreases in steps and passes into the neck 12, to which the spherical end 13 adjoins.

The control element 14 is embodied as a curved wire piece 15, the loop-shaped bent end 16 of which is fixed on the neck 12. The other end 17 of the wire part 15 goes out through the guide slot 18 and encloses the roller 19 on which the clamping roller 20 is mounted , performed mainly in the form of a double roller. In the longitudinal recess 5 a spring 21 is placed, pressing the clamping element 9 towards the end 7 of the housing. The front end of the spring 21 encloses the sharaoobrazny end 13 of the zanchnm element, allowing the latter to tilt in the direction of the channel 8, and with the embarrassment of the wire piece 15 arising, the roller 20 will somewhat more recede from the body. For the inserted wire, the control knob for the roller 20 is pulled aside, for example, the hook 3 or the karabiner hook 4. The fixed wire is inserted through the housing face hole into the channel S. When the roller 20 is released, the spring 21 presses the clamping element 9 to the fixed irovodu. The clamping element receives an inclined position, and its section 11 is adjacent to the fixed wire. In this case, the tensile force experienced by the latter is transmitted through the section // of the clamping element 9, as a result of which self-pinching of the element 9 is ensured. The device makes it possible to tighten the fastened cable without any effort. To do this, it is enough to grab and pull the end of the cable out of channel 8 more tightly. Self-pinching is immediately restored as soon as the fixed cable is released. To release or weaken the roller 20, the roller 20 is displaced along the body, so that, overcoming the force of the spring 21, to press the clamping element 9. It is possible to displace the hook 3 or the karabiner hook 4 while overcoming the force of the spring 22. Prulsina 22 provides the tensile force of the cable being fixed. In addition, it facilitates the insertion of a hook into the grip that secures it. The hook .3 or the karabiner hook 4 has a rod 23, on the end of which a nut 24 is screwed, resting on a dividing bar 25 into which a spring 21 rests on the opposite side. If the clamping device is intended to fix the cable or cable in a fixed part, for example in a cane embedded in the masonry, the tip carrying the hook or karabiner hook is screwed onto the body. If it is necessary to interconnect two cables or cables, two shells are screwed together. The spherical end 13 of the clamping element 9 can be fixed in the recess 26 of the control element 14, made in the form of a slider 27 sliding in the longitudinal recess 5. On the slider 27 there is a lever 28 rotatably mounted in the slot / 8. The lever 28 can also be displaced in longitudinal direction along the slot 18. The slider 27 is pressed by the coil spring 2.1 in the direction towards the end 7 of the housing. The clamping element is pressed against the fixed wire inserted into the channel 8. By pulling the wire branch out of the housing end hole, npvO, the clamping element 9 located on the wire surface and self-pinching is provided. To remove self-obstruction, squeeze back, overcoming the force of the coil spring 21, lever 25. To prevent inadvertent termination of self-squeezing, a spring 29 is placed in the slot 18, made of curved wire or strip. The ends of this spring are inserted into the holes or cut-outs of the side wall of the slot. The slotted wall / 5 facing the spring 29 is cut-out in section 30 in the section 30. In this construction, first release the lever 28 to release the self-pinch, overcome the force of the spring 21 and then press this lever towards the hook 3. The clamping element of the device can be made roller, flat profiled part. The clamping surface of the clamping member may have a shape corresponding to the shape of the flexible member to be bonded, may be concave, which prevents lateral sliding of the fixed member. The spring clamping the clamping member can be made either twisted conical or plate. The clamping device may be provided with a control knob connected either to the clamping element or with a spring acting on the clamping element. It is advisable to use several clamping devices arranged in a block 31 in parallel for two-sided connection of wires. Such an arrangement may find use for delaying a large number of cables or wires. In the clamping device for double-sided connection, the longitudinal section of the housing of which is shown in FIG. 9, the joined flexible elements are introduced into the cavities of the housing through two channels 8, which are offset 180 ° from each other. The longitudinal grooves, which are offset by 180 ° relative to each other, can be located in the housing either coaxially or with some axial displacement. In the case when flexible elements do not have free

the end for fastening, the clamping device shown in fig. 10 and 11, having a side slot 32 for insertion of a flexible element, cutting through the housing of the device from the outside to the channel for insertion of the fixed flexible element.

In this embodiment of the device, its body also has a G-shaped cross-section and can be made of two parts 33 and 34, fastened with rivets. In the upper part of the housing there is a longitudinal slot 18 in which a control element, made in the form of a slider, moves.

The slider has a part 35 located inside the housing. One end of the part 35 is skoschen and has a support 36, and the other - a recess 37 for the coil spring 21.

The upper part of the clamping element can be made convex, and the bottom concave. The spherical end 13 of the clamping element should be installed with a gap in the support 36. To prevent lateral sliding of the flexible element, the pressing surface of the clamping element 9 can be in the form of a connected flexible element.

The slot of the device body can be either semicircular or zigzag-shaped, which prevents the flexible element from slipping out, and the slots are made either permanently open, or closed with a lid or a sliding sleeve.
