Description

Technical Field

[0001] The utility model relates to the technical field of electrical cabinets, in particular to a cable inlet fixing device in a fire detection control cabinet. Background Art

[0002] In electrical equipment, instruments and meters that control various devices are often used together for easy operation. At the same time, the control cabinet protects the internal equipment from damage by the external environment. A large number of electrical equipment are connected to the internal control instruments through various cables that extend into the control cabinet. A large number of cables are concentrated in the cabinet. If they are not sorted out, they will be messy and affect operation. At present, several cables are generally tied and fixed by fixing devices such as line clips to limit the position.

[0003] However, most common wire clips are made of plastic, and use their own inverted tooth structure to bundle the cables. Most of them are disposable structures and are not easy to remove after being fixed. When the cables need to be adjusted, tools are often needed to destroy the binding, which causes waste and consumes a lot of energy in long-term use. Moreover, during operation, both installation and disassembly are inconvenient, which affects the operation work. In addition, common cabinets have openings for cables to be inserted. In order to ensure the entry of cables, the diameter of the openings is generally much larger than the cross-sectional diameter of the cables. This will cause external dust to enter the cabinet through the openings during actual work, affecting the operation of instruments and other equipment. Therefore, the equipment needs to be protected from dust. In addition, common wire clips are mostly made of plastic, so the cables are not firmly fixed. The cables are still easy to shake after being fixed. If the cables are tied tightly with great force, the cables may be damaged due to excessive pressure. Utility Model Content

The spherical end of the adjusting rod 3-5-1 is clamped in the spherical groove of the pressure block 3-5-3, so that the adjusting rod 3-5-1 can rotate relative to the pressure block 3-5-3. The pressure block 3-5-3 is located at the lower side of the cable cover 3-2, and the pressure block 3-5-3 is rotatably connected to the tail of the adjusting rod 3-5-1 to prevent the pressure block 3-5-3 from rotating and affecting the cable.

[0035] The pressure block 3-5-3 is an arc-shaped structure that matches the groove of the cable seat 3-1. The inner sides of the pressure block 3-5-3 and the cable seat 3-1 are both provided with a buffer pad 3-5-4. After inserting the cable, the cable cover 3-2 is buckled, the locking assembly 3-3 is inserted into the locking through hole 3-4 and locked, and the rotating handle 3-5-2 is rotated to move the pressure block 3-5-3 downward to apply pressure to the cable.

When the limit block 3-3-5 is located at the intersection of the annular limit groove 3-3-4 and the vertical limit groove 3-3-3, the rotary cover 3-3-2 can be rotated so that the limit block 3-3-5 slides along the circumference on the annular limit groove 3-3-4, thereby realizing the locking function.

[0037] like Figure 3 , Figure 5 and Figure 6 As shown, the dustproof assembly 4 includes an extension plate 4-1, which is a groove-shaped structure surrounded by a bottom and four sides. The four walls of the extension plate 4-1 and the bottom are combined to form a loading groove 4-5. The bottom plate of the extension plate 4-1 is provided with a wire hole 4-2, and the wire hole 4-2 is located above the wire inlet 1-1. A dustproof block 4-3 is arranged in the loading groove 4-5, and a wire hole 4-4 is arranged in the dustproof block 4-3.

[0038] A fixing frame 4-6 is provided above the extension plate 4-1. The fixing frame 4-6 is detachably connected to the extension plate 4-1 by screws. The fixing frame 4-6 is buckled on the dust block 4-3 to fix it. The number of dust blocks 4-3 is the same as the number of wire fixing components 3. The dust block 4-3 is made of rubber. An inlet 4-7 is provided at one end of the dust block 4-3. Both ends of the inlet 4-7 are tightly attached to facilitate the insertion of cables into the inlet 4-7.

[0039] like Figure 3 As shown, in this embodiment, a first guide rod 5 is provided above the dustproof assembly 4, and a second guide rod 6 is provided above the mounting seat 2. When in use, the cable extending from the dustproof block 4-3 passes under the first guide rod 5 to guide it into the wire fixing assembly 3, and the cable extending from the wire fixing assembly 3 passes under the second guide rod 6 to facilitate its cooperation with the electrical appliances in the cabinet.

[0040] like Figure 2 and Figure 3 As shown, in this embodiment, the mounting base 2 and the dustproof component 4 are arranged side by side, and mounting plates 2-1 are provided at both ends of the mounting base 2 and the dustproof component 4. A fixing port 2-2 is provided on the mounting plate 2-1, and a threaded hole 1-2 is provided at a position corresponding to the fixing port 2-2. The threaded hole 1-2 and the fixing port 2-2 are connected by bolts and nuts to fix the mounting base 2 and the dustproof component 4.

[0041] The action process of the utility model is as follows:

[0042] When the device is used, the wire hole 4-2 is aligned with the wire inlet 1-1, the extension plate 4-1 is placed above the wire inlet 1-1, the mounting base 2 is placed side by side with the extension plate 4-1, and the mounting base 2 is placed close to the inner side of the cabinet 1. The two mounting plates 2-1 clamp the mounting base 2 and the dustproof component 4, and the bolts are passed through the fixing port 2-2 and the threaded hole 1-2 and tightened to fix the mounting base 2 and the dustproof component 4. A plurality of horizontally arranged wire fixing components 3 are fixedly connected to the mounting base 2.

[0043] When connecting the cables, pass the cables through the cable inlet 1-1 and the cable hole 4-2 and then enter the cabinet 1, then separate the cables, select the appropriate cable seat 3-1 according to the cable access direction, then lift and rotate the cable cover 3-2 to expose the inner side of the cable seat 3-1, place the cables in the corresponding cable seat 3-1, buckle the cable cover 3-2, and after the other end of the cable cover 3-2 is in contact with the cable seat 3-1, the locking assembly 3-3 will be aligned with the locking through hole 3-4, so that the vertical limit groove 3-3-3 of the sliding column 3-3-1 moves downward along the limit block 3-3-5 and is inserted into the locking through hole 3-4, and when the limit block 3-3-5 is located at the intersection of the annular limit groove 3-3-4 and the vertical limit groove 3-3-3, the cover 3-3-2 can be rotated to make the limit block 3-3-5 slide along the circumference on the annular limit groove 3-3-4, thereby realizing the locking function. After the cable cover 3-2 restricts the cable, the adjusting rod 3-5-1 is controlled by rotating the handle 3-5-2 to rotate the adjusting rod 3-5-1, and the adjusting rod 3-5-1 cooperates with the cable cover 3-2 to move downward, driving the pressure block 3-5-3 to descend, so that the pressure block 3-5-3 applies pressure to the cable, and cooperates with the cable seat 3-1 to compress the cable. The pressure block 3-5-3 and the adjusting rod 3-5-1 can rotate to prevent the pressure block 3-5-3 from rotating and affecting the cable. The cable seat 3-1 and the pressure block 3-5-3 contact the cable through the buffer pad 3-5-4 to prevent the pressure from damaging the cable. In addition, when it is necessary to unlock and fix, it is only necessary to rotate the cover 3-3-2 to pull the sliding column 3-3-1 out of the locking hole 3-4, and then rotate the cable cover 3-2 to open it. When re-fixing, repeat the above steps and structures, each cable is fixed independently, and the operation can be performed without a workpiece.

[0044] After the cable is fixed, the dust block 4-3 is put on the cable. There is no need to insert the cable from the wire hole 4-4, and it can be directly inserted from the loading port 4-7. The rubber dust block 4-3 can open the loading port 4-7 for the cable to be loaded, and then it will close due to its own elasticity and store the cable in the wire hole 4-2, so that the dust block 4-3 slides along the cable and slides above the wire hole 4-2, and blocks the wire hole 4-2 to prevent external dust from entering the cabinet 1. The dust block 4-3 is clamped in the loading groove 4-5 so that the dust block 4-3 blocks the wire hole 4-2. After the installation of the cable and the dust block 4-3 is completed, the fixing frame 4-6 is fixed to the extension plate 4-1 by bolts so that the fixing frame 4-6 presses the dust block 4-3. After the dust block 4-3 is put into the loading groove 4-5 and pressed tightly, the loading port 4-7 will remain closed due to the squeezing, so that the dust block 4-3 can stably block the wire hole 4-2, ensuring the dustproof effect of the cabinet 1.

[0045] In addition, the cables in the dust block 4-3 pass under the first guide rod 5 to be guided into the wire fixing assembly 3, and the cables extending from the wire fixing assembly 3 pass under the second guide rod 6 to facilitate their cooperation with the electrical appliances in the cabinet.

[0046] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
