DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0022] Example:

[0023] See also Figure 1-Figure 3 As shown, a low-smoke halogen-free cable comprises a cable body 1, a mounting seat 3 and a locking half ring 4. The cable body 1 is evenly provided with wire cores 2. The mounting seat 3 is placed on one side of the cable body 1. A card slot 5 is provided on one side of the mounting seat 3. The card slot 5 is a semicircular shape adapted to the outer surface of the cable body 1. A locking half ring 4 is installed on one side of the mounting seat 3 by bolts. The stability of the connection between the mounting seat 3 and the cable body 1 is achieved by the cooperation between the locking half ring 4 and the bolts. During installation, the mounting seat 3 is evenly fixed on the surface of the cable body 1. The cable body 1 passes through the locking half ring 4 and the card slot 5. A card slot 5 is laterally provided below the surface of the mounting seat 3 on one side away from the card slot 5. A fixed plate 6, with a rubber pad A7 glued to its upper surface, a slide groove 8 is provided above the surface of the side of the mounting seat 3 facing away from the card slot 5, a slider 9 is slidably installed inside the slide groove 8, a movable splint 10 is provided on one side of the slider 9, the movable splint 10 can slide up and down along the track of the slide groove 8, and then the distance between the movable splint 10 and the fixed plate 6 is adjusted to achieve fixation with the mounting hanging rod, the movable splint 10 is placed on the outside of the mounting seat 3, the movable splint 10 is placed parallel to the top of the fixed plate 6, and a rubber pad B11 is glued to the lower surface of the movable splint 10, the rubber pad A7 and the rubber pad B11 can prevent the surface from being damaged due to excessive clamping force.

[0024] Among them, a sliding rod 13 is vertically fixed on the top of the slider 9, and the sliding rod 13 passes through the upper surface of the mounting seat 3. A pressure plate 14 is arranged on the top of the sliding rod 13, so that the clamping force of the movable splint 10 can be controlled by the top pressure plate 14. The pressure plate 14 is placed above the mounting seat 3, and positioning holes 131 are evenly opened on the surface of one side of the sliding rod 13 along the axis, so that no matter what height the movable splint 10 is at, it is limited by the positioning hole 131.

[0025] Please refer to Figure 3 and Figure 4 As shown, a spring A12 is arranged at the lower part of the slide groove 8, and the top of the spring A12 contacts the lower surface of the slider 9, so that the elastic force of the spring A12 can be used to enable the movable clamping plate 10 to move upward when it is not restricted, so as to increase the distance between it and the fixed plate 6.

[0026] Please refer to Figure 4 and Figure 5As shown, a sliding hole 15 is horizontally opened on the upper part of the slide groove 8, and a control board 16 is slidably installed on the inner side of the sliding hole 15. The control board 16 passes through the surface of one side of the mounting seat 3. When disassembling, the control is achieved by pushing the control board 16 that exceeds the inner side. A through groove 17 is opened on the surface of the control board 16, and the slide rod 13 passes through the through groove 17. A wedge block 18 is arranged on one side of the through groove 17. The wedge block 18 is adapted to the inner size of the positioning hole 131. The matching direction of the wedge block 18 must ensure that it is not hindered when the pressure plate 14 is pressed down, but it can be limited in real time to prevent the slide rod 13 from moving up.

[0027] Among them, a spring B19 is arranged inside the sliding hole 15, and one end of the spring B19 contacts the end surface of the control plate 16. The elastic force of the spring B19 causes the control plate 16 to be pushed to one side, so that the wedge block 18 can always cooperate with the positioning hole 131.

[0028] Working principle: When in use, the slider 9 is always subjected to an upward force due to the presence of the spring A12, thereby increasing the distance between the movable clamping plate 10 and the fixed plate 6, so as to facilitate installation with the mounting rod. At the same time, the control board 16 is always subjected to an outward thrust due to the presence of the spring B19, thereby making the wedge block 18 always keep in cooperation with the positioning hole 131, fitting the card slot 5 to the surface of the cable body 1, and ensuring the stability of the installation of the mounting seat 3 and the cable body 1 through the cooperation of the bolt and the locking half ring 4, so that The fixed plate 6 and the movable splint 10 are placed on both sides of the installation hanging rod, and the pressing plate 14 is pressed down to drive the slider 9 to move downward. The matching direction of the wedge block 18 and the positioning hole 131 must ensure the smoothness of the downward movement of the slide bar 13 and obtain real-time limit. The downward movement of the movable splint 10 can increase the squeezing of the installation hanging rod to achieve fixation. Conversely, during disassembly, the control plate 16 can be pushed inward to separate the wedge block 18 from the positioning hole 131. At this time, the elastic force of the spring A12 causes the movable splint 10 to move upward to achieve disassembly.

[0029] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
