Background

As a common transmission medium, cables are used to transmit signals between different electrical devices, and are increasingly used in power engineering. In a specific laying construction process, cables are often required to be placed neatly for laying convenience, namely, the positions of the cables are relatively fixed.

In the related art, due to the fact that the elevations of the cable bridge, the cable support and the electrical equipment are not consistent, the cables in the same cable bridge are placed disorderly. If the wiring position of a large motor and a cable bridge are not on a vertical plane, the difference of elevation is large, if a cable is directly hung from the bridge to the electric equipment for wiring, the cable is very messy, and due to vibration of the equipment during operation, the wiring position of a cable joint and the equipment is easy to loose due to self gravity and swing, so that the contact is poor, and great potential safety hazards are caused. To ensure that the cables are relatively fixed, plastic ties are typically used to bundle the cables during construction.

Meanwhile, the second link 222 is guided by the sliding sleeve 122, so that the second link 222 can only move along the inside of the sliding sleeve 122 when moving.

Illustratively, two struts 121 are fixed at two corners of the slat 11 symmetrically with the axis of the driving rod 21 as an axis, and an included angle between the axis of each strut 121 and the axis of the driving rod 21 is an acute angle.

In the above implementation manner, by symmetrically distributing the supporting rods 121 on two corners of the strip plate 11, it can be ensured that the acting force applied to the cable 100 on two sides is the same when the cable 100 is clamped, and it is ensured that the cable 100 can be uniformly stressed as much as possible without being crushed due to too much stress on one side.

Optionally, the control mechanism 2 further comprises a gear 23, the gear 23 is rotatably mounted on the bracket 1, the outer wall of the driving rod 21 is provided with a rack 211, the rack 211 and the gear 23 are meshed with each other, and a hexagonal threaded hole 230 is formed in the center of the gear 23.

It can be understood that the center of the gear 23 may be other types of holes, as long as the tool is inserted into the gear 23, and the rotation can be performed conveniently.

Fig. 2 is a state diagram of the cable fixing clamp provided by the embodiment of the disclosure clamping the cable, and in conjunction with fig. 2, optionally, the control mechanism 2 further includes an opening member 24, the opening member 24 includes a driving knob 241 and a holding plate 242, the driving knob 241 is rotatably installed on the bracket 1, the holding plate 242 is slidably installed on the bracket 1, the peripheral wall of the driving rod 21 has a holding strip 212, and the driving knob 241 is used for driving the holding plate 242 to slide so as to clamp the holding plate 242 and the holding strip 212 together.

In the above implementation, the opening member 24 is configured to control whether the driving rod 21 is going up and down, and when the driving rod 21 does not need to go up and down, the driving knob 241 is rotated to clamp the clamping plate 242 on the driving knob 241 and the clamping strip 212 on the driving rod 21, so that the driving rod 21 cannot move (see fig. 2). When the driving rod 21 needs to be lifted, the driving knob 241 can be rotated to separate the holding plate 242 on the driving knob 241 from the holding strip 212 on the driving rod 21, and the driving rod 21 can be lifted freely without any restriction of the holding plate 242.

The arrangement of the opening piece 24 in the above manner can ensure that the cable fixing clamp can be safely used without causing unnecessary problems due to random movement of the driving rod 21.

Illustratively, the drive knob 241 may be a gear knob structure and the catch plate 242 may be a long rack structure, wherein the racks of the catch plate 242 intermesh with the peripheral wall of the drive knob 241.

In the above implementation, by setting the driving knob 241 as a gear knob structure and the holding plate 242 as a long rack structure, the principle of engagement between the gear and the rack can be utilized to enable the holding plate 242 to move along an axis perpendicular to the driving rod 21 under the driving of the driving knob 241.

When the driving knob 241 is rotated clockwise, the holding plate 242 moves toward the driving rod 21 until the holding plate 242 abuts against the holding strip 212 on the driving rod 21, so as to lock the driving rod 21.

When the driving knob 241 is rotated counterclockwise, the catching plate 242 moves away from the driving lever 21, releasing the locking of the driving lever 21.

Illustratively, the snap strip 212 may also be a structural member of the same specification as the rack 211. Moreover, the clamping strip 212 and the rack 211 can be fixed on two opposite sides of the peripheral wall of the driving rod 21 in a welding manner, or the clamping strip 212, the rack 211 and the driving rod 21 are an integral structural member, as long as the above use requirements are met.

In the above implementation, by fixedly installing the limiting member 213 at the second end of the driving rod 21, when the driving rod 21 is lifted up and down through the engagement between the rack 211 and the gear 23, the driving rod 21 is not disengaged from the gear 23 due to carelessness at a moment, that is, the driving rod 21 loses control. That is, by providing the stopper 213, it is possible to prevent the gear 23 and the drive lever 21 from falling off from each other due to excessive rotation of the gear 23.

For example, the limiting member 213 may be a metal structural member such as a rod or a plate.

If the limiting member 213 is a rod member, the axis of the rod member is perpendicular to the axis of the driving rod 21.

If the limiting member 213 is a plate member, the plate surface of the plate member is arranged perpendicular to the axis of the driving lever 21.

Fig. 3 is a state diagram of the cable fixing clamp according to the embodiment of the present disclosure for further clamping a cable, and referring to fig. 3, in this embodiment, a plurality of locking holes 2221 are axially spaced on an outer wall of the second connecting rod 222, the locking holes 2221 are used for inserting fixing pieces 2222, and an outer wall of the fixing pieces 2222 abuts against the sliding sleeve 122.

In the above implementation manner, by providing a plurality of locking holes 2221, the fixing pieces 2222 can be inserted into the locking holes 2221 at different positions, so that the second link 222 can be clamped on the sliding sleeve 122 of the bracket 1 through the fixing pieces 2222.

For example, the sliding sleeve 122 may also be provided with fixing holes (not shown) corresponding to the locking holes 2221, and the fixing pieces 2222 are inserted into one of the locking holes 2221 and the fixing holes at the same time.

In the above implementation manner, by providing the plurality of locking holes 2221 and the fixing holes, the plurality of locking holes 2221 may respectively correspond to the fixing holes in sequence, and then the fixing member 2222 is inserted into the locking holes 2221 at different positions, so that the second connecting rod 222 can be fixed to the bracket 1 when moving to different positions, thereby improving the stability between the second connecting rod 222 and the bracket 1, and finally achieving the clamping and positioning of the clamping mechanism 3.

Fig. 4 is a schematic structural diagram of a link assembly provided in an embodiment of the present disclosure, and in conjunction with fig. 4, optionally, the rotating plate 223 is an obtuse triangle, the first connecting portion 2231 is located at a first acute angle of the rotating plate 223, the second connecting portion 2232 is located at a central position of the rotating plate 223, and the third connecting portion 2233 is located at a second acute angle of the rotating plate 223.

In the above implementation, by setting the rotating plate 223 as the obtuse triangle, it is not only convenient for the clamping rod 311, the connecting rod 312 and the elastic member 313 to have a sufficient installation space on the rotating plate 223, but also it is possible to secure the structural stability of the rotating plate 223.

In above-mentioned implementation, the setting of clamp block 3111 can conveniently carry out the centre gripping to cable 100, guarantees that cable 100 can not break away from this cable mounting fixture because of self weight when being centre gripping to cable 100 obtains the fixed of two clamp blocks 3111, and when cable 100 received external force, the vibration of cable itself was also little, and is also convenient when being connected between cable and the electrical equipment when using. The clamping surface 3112 can further improve the clamping of the cable by the clamping block 3111 to ensure that the cable does not fall off the clamp.

Optionally, the clamping surface 3112 is V-shaped.

Illustratively, the plane of symmetry of the V-profile is perpendicular to the length direction of drive rod 21.

In the above implementation, by setting the clamping surface 3112 to be a V-shaped surface, the cable can be accommodated in the V-shaped surface when the cable is clamped and fixed, and then the cable is supported by the V-shaped surface to bear part of the weight of the cable, so that the cable is prevented from being separated from each other only by the fact that the static friction clamp between the clamping block 3111 and the cable 100 is not tight.

It is understood that the clamping surface 3112 may also be other types of surfaces, such as concave surfaces, arcuate surfaces, and the like. This embodiment is not limited thereto.

By changing the shape of the clamping surface 3112, cables of different specifications and models can be clamped, or a plurality of cables can be clamped simultaneously.

Illustratively, the clamp block 3111 may be a rectangular parallelepiped structural member, and the clamp face 3112 is provided on an inner side face of the clamp block 3111 parallel to the axis of the drive lever 21.

Illustratively, all structures in the cable fixing clamp provided by the embodiment adopt metal structures, so that a large current can be effectively prevented from being generated when the cable is switched on or switched off, the cable 100 can generate strong vibration to damage the cable 100 fixing clamp, and the service life of the cable fixing clamp can be further prolonged.

Illustratively, the elastic member 313 may be a telescopic spring.

In the above implementation manner, by setting the elastic member 313 as a telescopic spring, on the one hand, it is convenient to connect the connection relationship between the connection rod 312 and the rotation plate 223, and on the other hand, it is also convenient to achieve the slow clamping of the clamping block 3111 by the telescopic spring, so as to avoid the cable 100 from being damaged due to the over-violent force.

The operation of the cable fixing clamp provided by the embodiment is briefly described as follows:

the cable fixing clamp provided by the present embodiment first rotates the driving knob 241 so that the catching plate 242 is away from the catching bar 212 on the driving lever 21 at the time of clamp-fastening the cable.

Then, the gear 23 is rotated counterclockwise, so that the gear 23 can drive the driving rod 21 to move downward when rotating, and the driving rod 21 moves downward and simultaneously drives the two first links 221 to move downward, so that an included angle between the two first links 221 is reduced. The first link 221 moves downward and simultaneously drives the second link 222 to move downward, and since the rotating plates 223 and the second link 222 are hinged together, the two rotating plates 223 move toward each other to drive the two clamping rods 311 to move toward each other until the two clamping rods are in contact with the cable 100 (see fig. 2).

When the cable needs to be further clamped, the driving rod 21 continues to move down, and the two clamping rods 311 also continue to clamp the cable 100, so that the clamping rod 311 on the left side drives the corresponding connecting rod 312 to rotate clockwise, and the clamping rod 311 on the right side drives the corresponding connecting rod 312 to rotate counterclockwise. During the rotation of the two connecting rods 312, the elastic members 313 are respectively pulled, so that after the driving rod 21 stops moving downwards, the two clamping rods 311 can still clamp the cable 100 (see fig. 3) under the action of the elastic members 313.

When the cable needs to be kept in a clamped state, the second link 222 and the sliding sleeve 122 can be fixed through the fixing part 2222 when the cable is clamped, so that the second link 222 is ensured to be stable relative to the sliding sleeve 122.

When it is desired to release the cable, which is the reverse of the process of clamping the cable, the fixing member 2222 is removed and then the gear 23 is rotated clockwise to move the driving rod 21 upward. And will not be described in detail herein.

The above description is intended to be exemplary only and not to limit the present disclosure, and any modification, equivalent replacement, or improvement made without departing from the spirit and scope of the present disclosure is to be considered as the same as the present disclosure.
