[0027] It should be noted that the clamping member 201 is used to clamp the cable. By providing the clamping member 201, the cable is fixed in a certain position to ensure that the cable will not shift when subjected to tension or pressure.

[0028] The second locking member 202 is used to fix the cable between the clamping member 201 and the second locking member 202, so that the cable can remain fixed under various environmental conditions to prevent the cable from being damaged or falling off due to vibration or external force.

[0029] Specifically, the first locking member 102 includes a first resistance block 102a, a stud 102b and a knob 102c. The stud 102b passes through the support block 101. One end of the stud 102b located in the support block 101 is fixedly connected to the first resistance block 102a. The end of the stud 102b away from the support block 101 is fixedly connected to the knob 102c. The knob 102c is used to adjust the length of the stud 102b entering the support block 101.

[0030] Among them, a locking hook 101a is provided on the support block 101, and the locking hook 101a is connected to the support block 101 through a connecting shaft. The locking hook 101a can rotate with the connecting shaft as the center of the circle.

[0031] Furthermore, the clamping member 201 includes a fixed block 201a, a second resistance block 201b and a tightening block 201c. The fixed block 201a is fixedly connected to the side of the support block 101 away from the locking hook 101a. The tightening block 201c is fixedly connected with a screw 201d, which passes through the fixed block 201a and is fixedly connected to the second resistance block 201b.

[0032] Example 2, reference Figure 1 to Figure 2, this embodiment 1 is different from the first embodiment in that: the fixing block 201a is composed of an arc portion 201a-1, a connecting portion 201a-2 and a locking portion 201a-3, the arc portion 201a-1 is connected to the connecting portion 201a-2, the connecting portion 201a-2 is connected to the locking portion 201a-3, the arc portion 201a-1 cooperates with the second interference block 201b to lock the cable, the connecting portion 201a-2 is used to support and connect the locking portion 201a-3 and the arc portion 201a-1, and the locking portion 201a-3 is used to lock the position of the second interference block 201b.

[0033] Specifically, the side of the arc portion 201a-1 close to the knob 102c is arc-shaped, and the side of the fixed block 201a close to the second contact block 201b is provided with friction grooves. The purpose of such a setting is to increase the friction between the wire clamp and the cable surface and reduce the occurrence of cable displacement and falling off.

[0034] Furthermore, the second locking member 202 is arranged at the end of the locking portion 201a-3, and the second locking member includes a pushing element 202a, an elastic element 202b and a locking element 202c; the pushing element 202a includes a pushing block 202a-1 and a threaded column 202a-2 fixedly connected to the pushing block 202a-1, the elastic element 202b is arranged between the locking portion 201a-3 of the fixed block 201a and the locking element 202c, and the locking element 202c is used to lock the position of the second interference block 201b.

[0035] Furthermore, the elastic element 202b includes an elastic sheet 202b-1, and the locking element 202c includes a first locking block 202c-1. A first ratchet is provided on a side of the first locking block 202c-1 close to the second abutting block 201b, and a second ratchet is provided on a side of the second abutting block 201b close to the locking block, and the first ratchet and the second ratchet are adapted to each other; the threaded column 202a-2 passes through the locking portion 201a-3 and the elastic sheet 202b-1 and is threadedly connected to the locking block; the first locking block 202c-1 and the locking portion 201a-3 are connected by mortise and tenon, and the locking block can be on the threaded column 202a -2 is driven to rotate. Here, the first locking block 202c-1 is set to be able to rotate a certain angle within the fixed block 201a. The purpose is to adjust the self-locking state of the first ratchet and the second ratchet. Since the movement directions of the first locking block 202c-1 and the threaded column 202a-2 are opposite, when the threaded column 202a-2 moves toward the first locking block 202c-1, the first locking block 202c-1 will move toward the threaded column 202a-2. At this time, the first locking block 202c-1 will release the locking state with the second interference block 201b, thereby providing a second safety for the wire clamp.

[0036] In this embodiment, first, the cable needs to be passed through the support block 101 to ensure that the cable is located between the support block 101 and the first locking member 102, so that the cable is hooked. Then, by turning the knob 102c, the first resisting block 102a is pushed to move toward the cable until the cable is tightly clamped.

[0037] Then, the wire needs to pass through the space between the second contact block 201b and the fixed block 201a. Ratchets in opposite directions are designed on the contact surfaces of the second contact block 201b and the first locking block 202c-1. In this way, when the second contact block 201b is pushed, it can only move forward in one direction, thereby realizing a self-locking function and ensuring that the cable will not loosen due to vibration or external force during long-term operation.

[0038] If the wire clamp needs to be disassembled or reinstalled, since the first locking block 202c-1 is provided with threads and is adapted to the threaded column 202a-2, the first locking block 202c-1 can be rotated by tightening and releasing the threaded column 202a-2. When the threaded column 202a-2 moves toward the first locking block 202c-1, the first locking block 202c-1 moves toward the threaded column 202a-2, that is, when the threaded column 202a-2 is rotated to move toward the second contact block 201b, the movement directions of the second contact block 201b and the threaded column 202a-2 are opposite, so that the second contact block 201b and the ratchet on the first locking block 202c-1 no longer contact each other, so that the first locking block 202c-1 can be allowed to retreat, providing the necessary space for reinstalling the wire. Through this series of operations, the hanging point fixing device can efficiently and stably fix the cable, and can also be easily disassembled and reinstalled when necessary.

[0039] The rest of the structure is the same as that of Example 1.

[0040] Example 3, reference Figure 1 and Figure 3 , this embodiment is different from the above embodiments in that: the elastic element 202b includes a spring 202b-2, the locking element 202c includes a second locking block 202c-2, a third ratchet is provided on the side of the second locking block 202c-2 close to the second interference block 201b, and a fourth ratchet is provided on the side of the second interference block 201b close to the second locking block 202c-2, and the third ratchet and the fourth ratchet are adapted to each other; one end of the threaded column 202a-2 away from the pushing block 202a-1 is fixedly connected to the second locking block 202c-2; a movable groove is provided at one end of the locking portion 201a-3 connected to the second locking block 202c-2, and an end of the second locking block 202c-2 away from the third ratchet is inserted into the movable groove.

[0041] It should be noted that, in this embodiment, one end of the second locking block 202c-2 is inserted into the movable groove of the locking part 201a-3 of the fixed block 201a, so that the second locking block 202c-2 can move along the movable groove, and the second locking block 202c-2 is connected to the threaded column 202a-2 by threads and has the same movement direction. A spring 202b-2 is arranged between the second locking block 202c-2 and the fixed block 201a, which is used to better resist the second locking block 202c-2 in the direction of the second resistance block 201b.

[0042] The rest of the structure is the same as that of Example 2.

[0043] In this embodiment, first, the cable needs to be passed through the support block 101 to ensure that the cable is located between the support block 101 and the first locking member 102, so that the cable is hooked. Then, by turning the knob 102c, the first resisting block 102a is pushed to move toward the cable until the cable is tightly clamped.

[0044] Then, the wire needs to pass through the space between the second contact block 201b and the fixed block 201a. Ratchets in opposite directions are designed on the contact surfaces of the second contact block 201b and the second locking block 202c-2. In this way, when the second contact block 201b is pushed, it can only move forward in one direction, thereby realizing a self-locking function and ensuring that the cable will not loosen due to vibration or external force during long-term operation.

[0045] If the wire clamp needs to be disassembled or reinstalled, since the second locking block 202c-2 is provided with threads and is adapted to the threaded column 202a-2, the second locking block 202c-2 can be rotated by tightening and releasing the threaded column 202a-2. Since the threaded column 202a-2 is connected to the second locking block 202c-2 by threads and has the same movement direction, when the threaded column 202a-2 is rotated to move the threaded column 202a-2 away from the second locking block 202c-2, the second locking block 202c-2 also moves at the same time, so that the second contact block 201b and the ratchet on the second locking block 202c-2 no longer contact each other, so that the second locking block 202c-2 can be allowed to retreat, providing the necessary space for reinstalling the wire. Through this series of operations, the hanging point fixing device can efficiently and stably fix the cable, and can also be easily disassembled and reinstalled when necessary.
