Through the combined use of a first fixing plate, a threaded sleeve, a rotating screw rod and a second fixing plate, the utility model can fix the connection part of the cable. After connecting two groups of cables, fixing them can effectively avoid the situation that when the cables are connected at high altitude, the cables shake due to strong wind weather, resulting in the disconnection of the cable connection. Therefore, after fixing, the stability between the connection parts of the two groups of cables can be increased, the situation of cable disconnection can be reduced, and the protection of the cable connection part can be increased.

[0004] Existing cable buckles are prone to loosening during long-term use, resulting in cable disconnection or position deviation. This situation will cause instability of the electric power system and may even lead to short circuits or power outages, seriously affecting the continuity and safety of power supply.

Detailed Embodiment

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] The present invention provides two technical solutions:

[0025] Figures 1-3The first embodiment is shown: A cable buckle protection structure for electrical installation, including a protection box 1. Inlet holes 2 are provided on both sides of the protection box 1. A protection device is provided inside the protection box 1. The protection device includes: a protection component 4, which is arranged inside the protection box 1 to protect the cable. The protection component 4 includes a base 41 arranged inside the protection box 1. Threaded holes 42 are provided on the base 41. A support rod is provided at the bottom of the base 41. A clamping platform 43 is fixedly arranged on the base 41. A hoop piece 44 is arranged on the clamping platform 43. A buffer spring 45 is fixedly arranged inside the hoop piece 44. An arc-shaped fixing plate 46 is fixedly arranged at the output end of the buffer spring 45. A retaining platform 47 is fixedly arranged at the end of the hoop piece 44. A fixed threaded rod 48 is movably arranged on the retaining platform 47. A buckle is fixedly arranged at the bottom of the retaining platform 47. A clamping groove matching the buckle is provided on the clamping platform 43. A convex rib 49 is fixedly arranged on the arc-shaped fixing plate 46;

[0026] A positioning component 5, which is arranged on both sides of the protection component 4 to position the cable.

[0027] By rotating the fixed threaded rod 48 on the retaining platform 47, the hoop piece 44 is separated from the base 41, and the cable is placed inside the hoop piece 44. Then the fixed threaded rod 48 is rotated again and placed into the threaded hole 42 to provide a clamping force for the hoop piece 44, thereby realizing the fixation of the cable, enabling it to fix cables of different sizes, thus improving its applicability. At the same time, through the cooperation of the buffer spring 45 and the arc-shaped fixing plate 46, the clamping force generated on the surface of the cable is buffered, reducing the phenomenon of cable damage caused by excessive clamping force, thereby improving its protection performance. And the convex rib 49 on the arc-shaped fixing plate 46 is used to increase the friction between the cable and the arc-shaped fixing plate 46, preventing the cable from sliding inside the buckle, ensuring that the cable will not loosen or fall off during long-term use, and guaranteeing its protection performance.

[0028] Figure 1 and 3-5 shows the second implementation mode. The main difference from the first implementation mode is that the positioning component 5 includes positioning plates 51 fixedly arranged on both sides of the base 41. Multiple groups of positioning grooves 52 are formed in the positioning plates 51. An arc-shaped limiting plate 54 is fixedly connected inside the positioning groove 52 through a fixing spring B53. A protective rubber pad is fixedly arranged on the surface of the arc-shaped limiting plate 54 that contacts the product. An activity groove is formed in the protective box 1 at the position of the wire inlet hole 2. A fixing plate A8 and a fixing plate B9 are fixedly connected inside the activity groove through a return spring 7, and the fixing plate A8 can be accommodated in the fixing plate B9. A connecting block 10 is fixedly arranged on one side of the protective box 1, and a connecting groove 11 matching the connecting block 10 is fixedly arranged on the other side of the protective box 1. Multiple protective boxes 1 can be connected together through the cooperation of the connecting block 10 and the connecting groove 11, so as to meet the demand for the number of protective boxes 1 in different environments, and thus improve its applicability. The protective box 1 is an insulating plastic structure body or an insulating ceramic structure body. The protective box 1 is divided into an upper protective box 14 and a lower protective box 15. A fixing groove 12 is formed in the box wall of the lower protective box 15, and a fixing block 13 matching the fixing groove 12 is fixedly arranged on the box wall of the upper protective box 14.

[0029] Through the cooperation of the arc-shaped fixing plate 46 in the positioning groove 52 on the positioning plate 51 and the fixing spring B53, the positioning of the cable is realized, and the situation of the cable shaking during the installation process is reduced, so that the installation effect of the cable can be improved, and the installation efficiency of the cable can be further improved. At the same time, through the cooperation of the fixing plate A8 and the fixing plate B9 in the wire inlet hole 2, the cable is fixed, and at the same time, the wire inlet hole 2 is sealed, so that the inside of the protective box 1 is in a relatively dry environment, and then the phenomenon of short circuit caused by moisture at the cable connection is realized, thereby improving its protection performance.

[0030] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0031] When in use, the fixing block 13 on the upper protective box 14 is removed from the fixing groove 12 on the lower protective box 15, so as to open the protective box 1. Then, by rotating the fixing threaded rod 48 on the retaining platform 47, the hoop piece 44 is separated from the base 41, and the cable is placed in the hoop piece 44. Then, the fixing threaded rod 48 is rotated again and placed into the threaded hole 42 to provide a clamping force for the hoop piece 44, thereby realizing the fixation of the cable. At the same time, the buffer spring 45 and the arc-shaped fixing plate 46 cooperate with each other to buffer the clamping force generated on the surface of the cable, reduce the phenomenon that the cable is damaged due to excessive clamping force, and increase the friction between the cable and the arc-shaped fixing plate 46 through the convex ribs 49 on the arc-shaped fixing plate 46 to prevent the cable from sliding in the buckle, ensuring that the cable will not loosen or fall off during long-term use, guaranteeing its protection performance. And through the cooperation of the arc-shaped fixing plate 46 in the positioning groove 52 on the positioning plate 51 and the fixing spring B53, the cable is positioned, reducing the shaking of the cable during the installation process, so as to improve the installation effect of the cable and further improve the installation quality of the cable. After the fixation is completed, by placing the fixing block 13 on the upper protective box 14 into the upper fixing groove 12 in the lower protective box 15, the sealing of the protective box 1 is realized, and the cable is fixed through the cooperation of the fixing plate A8 and the fixing plate B9 in the inlet hole 2, and at the same time, the feeding hole is sealed, so that the inside of the protective box 1 is in a relatively dry environment, thereby realizing the phenomenon that the cable connection is short-circuited due to moisture, and improving its protection performance.
