Detailed ways

A kind of self-locking cable clamp with unlocking mechanism of the present invention will be further described below in conjunction with accompanying drawing:

Example 1:

As shown in Figure 1, a self-locking cable clamp with an unlocking mechanism includes a connecting clamp, the connecting clamp includes a clamp body 1, a groove 2 is provided in the clamp body 1, and the groove 2 is embedded There is a movable chuck 3 that can move up and down, and the clamp body 1 is fixedly connected with a static chuck 4 opposite to the clamping end of the movable chuck 3. The side of the clamp body 1 opposite to the opening of the groove 2 is provided with A bolt hole, an adjusting bolt 5 passes through the bolt hole and is fixedly connected with the clamp body 1, and connects with the movable chuck 3 at the same time, and one side of the movable chuck 3 connected to the wire clamp is provided with a downward stop Inverse sawtooth, the outer side of the anti-reverse sawtooth of the movable chuck 3 is provided with an anti-loosening and anti-reversal sawtooth block 6 that cooperates with it. The end of the anti-loosening anti-reversing sawtooth block 6 close to the adjusting bolt 5 is its lower end, and the side of the anti-loosening anti-reversing sawtooth block 6 that cooperates with the movable chuck 3 is provided with an upward anti-reversing anti-reversing sawtooth, which is used for anti-loosening. The inner side of the anti-reverse sawtooth block 6, and the opposite side is the outer side of the anti-loosening anti-reverse sawtooth block 6, and a compression spring 8 is arranged between the outer side of the anti-loosening anti-reverse sawtooth block 6 and the clamp body 1, and the movable chuck 3 and the anti-loose anti-reverse sawtooth block 6 are pressed tightly by the compression spring 8, and the side of the anti-loosening anti-reverse sawtooth block 6 close to the compression spring 8 is provided with the anti-reverse sawtooth and the anti-reverse sawtooth of the movable chuck 3 Released unlocking mechanism.

Preferably, the anti-loosening and anti-reverse sawtooth block 6 is hinged with the clamp body 1 , and the unlocking mechanism includes an unlocking lever 9 that is fixedly connected or abutted with the anti-loosening and anti-reversal sawtooth block 6 . Wherein the stage clip 8 is a wavy leaf spring or a columnar spring, and one or more stage clips 8 can be arranged on the outside of the anti-loosening and anti-reversing sawtooth block 6. If only one large leaf spring is set, the leaf spring can correspond to The position where the unlocking lever 9 is provided is provided with a corresponding opening or through hole for the unlocking lever 9 to pass through.

Preferably, the lower end or the upper end of the anti-loosening and anti-reverse sawtooth block 6 is hinged with the side of the clamp body 1 on the outside through a rotating shaft 7, and the anti-reverse sawtooth of the corresponding anti-loosening and anti-reverse sawtooth block 6 is arranged on the anti-loosening and anti-reverse sawtooth On the side of the upper end or the lower end of the block 6, the unlocking lever 9 is a pull rod, and the side of the clamp body 1 is provided with a through hole for the pull rod to pass through. The anti-return sawtooth setting end is fixedly connected. That is to say, the following two methods can be used: the first method (as shown in Figure 1) is to set the part connected to the rotating shaft at the lower end of the anti-loosening and anti-reversing sawtooth block 6, and the corresponding pull rod is set on the anti-loosening and anti-reversing The upper end of the sawtooth block 6; in the second way, the part connected to the rotating shaft is arranged on the upper end of the anti-loosening and anti-reversal sawtooth block 6, and the corresponding pull rod is arranged at the lower end of the anti-loosening and anti-reversal sawtooth block 6;

Preferably, the unlocking lever 9 is an unlocking bolt, which is fixedly connected with the anti-loosening and anti-reversing saw-toothed block 6 through a screw hole provided on the anti-loosening and anti-reversing saw-toothed block 6 .

Preferably, the size of the through hole through which the unlocking lever 9 passes is larger than the outer diameter of the unlocking lever 9 provided at the position corresponding to the unlocking lever 9 on the wire clamp body 1, and the unlocking lever 9 is loosely fitted with the through hole; The through hole corresponding to the rod 9 is a screw hole, and the unlocking rod 9 is fixedly connected with the through hole through threads. The most preferred way is that the unlocking lever is a pull rod, and it only penetrates into the groove from the outside of the clamp body 1 and is fixedly connected with the anti-loosening anti-reverse sawtooth block 6 (such as the two are threaded), but there is no connection with the clamp body 1. Direct connection relationship, the size of the corresponding through hole on the clamp body 1 is larger than the outer diameter of the unlocking lever. In this way, unlocking is the most convenient, and the movable chuck can be unlocked by simply pulling the unlocking lever outward.

When in use, just put the cable between the movable chuck 3 and the static chuck 4, adjust the adjusting bolt 5 to move the movable chuck to the direction of the static chuck 4 until the cable is clamped, and only It is necessary to move the unlocking lever 9 in the direction opposite to the direction in which the anti-loosening anti-reverse sawtooth block 6 abuts against, so that the anti-loosening anti-reverse sawtooth block 6 moves toward the direction of the compression spring 8 outside the outer side of the anti-loosening anti-reverse sawtooth block 6 to Loosen the movable chuck 3 that is restricted in its downward movement to realize the unlocking of the movable chuck 3. After unlocking, adjust the adjusting bolt 5 to move in the opposite direction of the movable chuck, and the movable chuck 3 moves downward. Stay away from the static clamp 4, loosen the cable, and then the cable clamp can be taken off from the cable. It is also possible to adjust the adjusting bolt 5 first, and then unlock the locking chuck 3 .

A self-locking cable clamp with an unlocking mechanism in this embodiment can be self-locking, has a simple structure, and is easy to assemble. Due to the setting of the unlocking mechanism, it is easy to loosen the anti-loosening and anti-reversing sawtooth block, and release its lock on the movable chuck. Tight function, easy to unlock, can be reused, saving resources.
