It should be understood that the specific implementation manners described herein are only for the purpose of illustrating and explaining the present invention, and the protection scope of the present invention is not limited to the following specific implementation manners.

[0034] In the description of the present invention, it should be noted that, unless otherwise clearly defined and limited, the terms "arranged", "installed", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0035] In the description of the present invention, it should be understood that the orientation terms are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0036] See Figures 1 to 4 , the present invention provides a cable guiding and fixing device for a fan bellows, including a semi-closed cable fixing part 1 and a fixing band 2. A plurality of first fixing holes 101 are provided on the cable fixing part 1, and a plurality of second fixing holes 201 are provided on the fixing band 2. The first fixing holes 101 and the second fixing holes 201 are connected by a first fastener 6 so that the cable fixing part 1 and the fixing band 2 can form an adjustable connection, thereby being able to fix and tighten the outer peripheral surface of cables with different diameters. The cable fixing part 1 is connected to the device housing 3. A hanging hook 4 and a roller 5 are provided on the device housing 3. The hanging hook 4 is used to connect with a towing rope, and the roller 5 can drive the cable guiding and fixing device for the fan bellows to move along the inner wall of the bellows when the towing rope is pulled.

[0037] In the above basic implementation manner, the cable guiding and fixing device for the fan bellows of the present invention can be made of a metal material, such as copper or iron, etc., as Figure 1 , Figure 2 and Figure 4As shown, to facilitate the connection between the cable fixing part 1 and the fixing belt 2, the cable fixing part 1 is formed into an open structure. Specifically, the outer peripheral surface of the cable fixing part 1 is a semi-closed structure. The outer peripheral surface of the cable fixing part 1 can be understood as the side surface of the cable fixing part 1, and the unclosed side thereof can be connected to the fixing belt 2. In the present invention, by connecting the cable fixing part 1 and the fixing belt 2, the cable is fixed by the cooperation of the cable fixing part 1 and the fixing belt 2. To be able to fix the cable, the combination of the cable fixing part 1 and the fixing belt 2 can enclose the outer peripheral surface of the cable. It can be imagined that spaces suitable for the cable to pass through are provided at both ends of the cable fixing part 1. To increase the friction force of the contact surface between the cable and the fixing belt 2 to ensure that the cable is not easily slipped or moved after being fixed and make the cable fixing more stable, the fixing belt 2 can be made of a flexible material. Preferably, it can be made of rubber. Of course, the way to achieve the above technical effect of stable cable fixing is not limited to this. However, the present invention does not need to rely on external objects and can achieve the corresponding effect only by using physical principles. In the prior art, when fixing a cable, tape and cable ties are required, and the tape and cable ties are removed after the process of the cable passing through the corrugated pipe. Garbage will be generated during this period, polluting the environment, and the operation is more cumbersome. Moreover, during the process of the cable passing through the corrugated pipe, it is also very easy for the tape, cable ties, etc. to fall off, affecting the work efficiency. Compared with the prior art, the present invention can reduce environmental pollution and is more clean and environmentally friendly.

[0038] As is well known, a cable is a device for transmitting electric energy or signals, usually composed of several or several groups of wires. During the actual working process, the cable fixed by the cable fixing part 1 and the fixing belt 2 can include a power line, a communication line, a network cable, etc. The number of strands and specifications of the cable will be configured according to actual needs. Therefore, the diameters of the cables to be fixed will be different. To be able to adjust the connection position between the fixing belt 2 and the cable fixing part 1 according to the number of strands and specifications of different cables so as to fasten multi-strand cables with different diameters, a plurality of first fixing holes 101 are provided on the cable fixing part 1, and a plurality of second fixing holes 201 are provided on the fixing belt 2. The first fixing holes 101 and the second fixing holes 201 are connected by a first fastener 6. It can be imagined that the first fastener 6 can be a pin, a bolt or a screw. The present invention can correspond the first fixing holes 101 at different positions to the second fixing holes 201 at different positions and connect them by using the first fastener 6 so as to adapt to cables with different diameters. Since there are more choices for the connection positions, the diameters of the cables that can be adapted are also more, the adaptability is stronger, and the use effect is better.

[0039] The exterior of the cable fixing part 1 and the fixing belt 2 is the device housing 3. The device housing 3 is connected to the cable fixing part 1. Preferably, both ends of the device housing 3 are set to be non-closed to facilitate the placement of the cable. In order to drive the cable to move in the corrugated pipe, a hanging buckle 4 and a roller 5 are provided on the device housing 3. The roller 5 is the main moving part in the cable guiding and fixing device for the fan corrugated pipe of the present invention. The hanging buckle 4 is used to connect with the towing rope. Thus, when the towing rope is pulled, the cable guiding and fixing device for the fan corrugated pipe of the present invention is driven to move in the corrugated pipe by the pulling force. For the same object, since the rolling friction generated by it on another object is less than the sliding friction generated, therefore, it is more time-saving and labor-saving for the cable guiding and fixing device for the fan corrugated pipe of the present invention to drive the cable to cross in the corrugated pipe.

[0040] As can be seen from the above description, after the cable fixing part 1 and the fixing belt 2 are connected, the cable is fixed and tightened in a manner that encloses the outer peripheral surface of the cable. Therefore, in order to better fit the outer peripheral surface of the cable, as a preferred embodiment of the cable fixing part 1 of the present invention, from Figure 1 、 Figure 2 and Figure 4 it can be seen that the cross-section of the cable fixing part 1 is set to an arc-sector shape or a semi-circular ring structure. A plurality of first fixing holes 101 are arranged along the length direction of the cable fixing part 1. A plurality of first through holes 102 corresponding to the first fixing holes 101 are provided on the side length direction of the cable fixing part 1. The first through holes 102 are used to penetrate the fixing belt 2 to facilitate the connection between the fixing belt 2 and the cable fixing part 1. The first fixing holes 101 and the second fixing holes 201 are formed as through holes. The first fixing holes 101 are communicated with the first through holes 102. When the fixing belt 2 penetrates the first through holes 102, the first fastener 6 can sequentially pass through the first fixing holes 101 and the second fixing holes 201 to tightly connect the fixing belt 2 and the cable fixing part 1. It can be imagined that a connection hole for facilitating the fixing of the first fastener 6 is also provided at the bottom position in the first through holes 102, and the connection hole and the first fixing holes 101 can be concentric holes. The fixing belt 2 is formed into a strip structure. It can be imagined that a plurality of second fixing holes 201 can be arranged along the length direction of the fixing belt 2.

[0041] Preferably, the device housing 3 mainly includes two parts, namely the first device housing 301 and the second device housing 302. The device housing 3 is located outside the cable fixing part 1. Among them, a connecting block is provided on the inner wall of the second device housing 302, and the cable fixing part 1 is connected to the second device housing 302 through the connecting block. The cable fixing part 1, the connecting block and the second device housing 302 can be integrally formed, or can be connected by welding or fasteners. For the convenience of fixing the cable, the first device housing 301 and the second device housing 302 are preferably detachably connected. The cross-section of the second device housing 302 can be set as an arc-sector or a semi-circular ring. It has been described above that the cross-section of the cable fixing part 1 is also an arc-sector or a semi-circular ring, and the cross-section of the second device housing 302 and the cross-section of the cable fixing part 1 are concentric.

[0042] More preferably, in order to increase the friction between the cable and the cable fixing part 1, so that the cable is less likely to slip during transportation, a rubber layer is provided on the inner wall of the cable fixing part 1.

[0043] As another preferred embodiment of the present invention, for the convenience of assembling with the second device housing 302, the cross-section of the first device housing 301 is set as an arc-sector or a semi-circular ring. Connecting grooves 3010 are provided on both sides of the first device housing 301, and connecting plates 3020 matching the connecting grooves 3010 are provided on both sides of the second device housing 302. When assembling the first device housing 301 and the second device housing 302, just align the connecting plate 3020 and insert it into the connecting groove 3010, then the positioning between the first assembly housing and the second device housing 302 can be completed.

[0044] From the above description, it can be seen that the cross-sections of the first device housing 301, the second device housing 302 and the cable fixing part 1 are all arc-sectors or semi-circular rings. Among them, the cross-sections of the first device housing 301 and the second device housing 302 can be semi-circular rings with the same diameter, so as to facilitate the docking between them.

[0045] For the connecting plate 3020 and the connecting groove 3010, in addition to the above positioning function, they also have the function of fixed connection. As another preferred embodiment of the present invention, a second through hole corresponding to the connecting groove 3010 is provided on the end face of the first device housing 301. The second through hole can insert the second fastener 7 to connect the first device housing 301 and the connecting plate 3020. That is to say, the second through hole communicates with the connecting groove 3010, so that the second fastener 7 can be inserted into the connecting groove 3010. A connecting hole of the connecting plate 3020 concentric with the second through hole can be provided on the connecting plate 3020, and the connecting hole of the connecting plate 3020 is also a through hole, so as to facilitate the second fastener 7 to sequentially pass through the second through hole and the connecting hole of the connecting plate 3020 to fasten and connect between the first device housing 301 and the second device housing 302.

[0046] As a specific structural form of the present invention, the hanging buckle 4 is formed in a C shape, and the hanging buckle 4 can be connected to the device housing 3. Specifically, insertion ends are provided at both ends of the hanging buckle 4, and fixed ends are provided at the ends of the insertion ends. A reserved hole for inserting the insertion ends to fix the hanging buckle 4 is provided at the joint of the first device housing 301 and the second device housing 302. When installing the hanging buckle 4, the first device housing 301 and the second device housing 302 can be butted first, and then the insertion ends of the hanging buckle 4 are inserted into the reserved holes for fixation. Of course, the insertion ends can also be inserted into the reserved hole positions first, and then the first device housing 301 and the second device housing 302 are butted.

[0047] Specifically, the insertion ends are perpendicularly connected to both ends of the hanging buckle 4. It is not difficult to think that in order to prevent the insertion ends from falling out of the reserved holes, the fixed ends can be perpendicularly connected to both ends of the insertion ends, and it is necessary to ensure that the length of the fixed ends matches the diameter of the reserved holes, so as to ensure that the fixed ends are fixed in place and will not easily come off, preventing the risk of falling off during later traction.

[0048] As another specific structural form of the present invention, in order to facilitate the cable guiding and fixing device for the blower bellows of the present invention to smoothly cross through the bellows, the rollers 5 are symmetrically arranged along the vertical direction of the device housing 3 and close to the edge of the device housing 3, and the rollers 5 are evenly distributed in a 120-degree array on the outer peripheral surface of the device housing 3. Due to the scattered and uniform arrangement of the rollers 5, the cable guiding and fixing device for the blower bellows of the present invention can maintain the balance of the device itself when crossing through the bellows and will not cause damage to the bellows.

[0049] As yet another specific structural form of the present invention, as Figures 1 to 4As shown, the roller 5 is connected to the device housing 3 through a bracket 8. The bracket 8 can be strip-shaped, with a long groove in the middle for facilitating the installation of the roller 5. The rollers 5 in the same axial direction can adopt the same bracket 8. The installation method between the roller 5 and the bracket 8 can refer to the common caster structure. Since this installation method is not within the protection scope of the present invention, it will not be described in detail here.

[0050] In summary, as an optimal embodiment of the present invention, the cable guiding and fixing device for a fan bellows of the present invention includes a semi-closed cable fixing part 1 and a fixing band 2. The cable fixing part 1 is provided with a plurality of first fixing holes 101, and the fixing band 2 is provided with a plurality of second fixing holes 201. The first fixing holes 101 and the second fixing holes 201 are connected by a first fastener 6 so that the cable fixing part 1 and the fixing band 2 can form an adjustable connection, thereby being able to fix and tighten the outer peripheral surface of cables of different diameters. The device housing 3 includes a first device housing 301 and a second device housing 302. The outer wall of the cable fixing part 1 is connected to the inner wall of the second device housing 302. The inner wall of the cable fixing part 1 is provided with a rubber layer, which can increase the friction between the cable and the cable fixing part 1 and prevent the cable from slipping during transportation. The cross-section of the first device housing 301 and the cross-section of the second device housing 302 are set to be arc-shaped. Two sides of the first device housing 301 are provided with connection grooves 3010, and two sides of the second device housing 302 are provided with connecting plates 3020 that cooperate with the connection grooves 3010, which can facilitate the assembly between the first device housing 301 and the second device housing 302. The device housing 3 is provided with a hanging buckle 4 and rollers 5. The hanging buckle 4 is formed in a C shape. The two ends of the hanging buckle 4 are vertically connected to the insertion end, and the end of the insertion end is vertically connected to the fixed end. A reserved hole for inserting the insertion end to fix the hanging buckle 4 is provided at the joint of the first device housing 301 and the second device housing 302. The length of the fixed end matches the diameter of the reserved hole, so as to ensure that the fixed end is fixed in place and will not easily unhook, preventing the risk of falling during later traction. The rollers 5 are symmetrically arranged along the vertical direction of the device housing 3 and close to the edge of the device housing 3, and the rollers 5 are evenly distributed in a 120-degree array on the outer peripheral surface of the device housing 3, which can keep the cable guiding and fixing device for a fan bellows of the present invention balanced and stable during the process of crossing the bellows and will not cause damage to the bellows.
