Description

Technical Field

[0001] The present invention relates to the technical field of cable installation, and in particular, to a cable fixing device in a pipeline. Background Art

[0002] At present, due to the importance of cables in the communication field, it is necessary to organize and protect the cables. Generally, the method is to pass the cables through a pipeline to protect the cables from weathering and aging or being damaged and broken by external objects. The existing method is to pass multiple cables through the pipeline. Although the pipeline realizes the protection of the cables, in actual situations, the cables often get disordered and knotted in the pipeline. Moreover, under the pulling of external forces, since multiple cables are not bundled in the pipeline through special treatment, when one or more cables move, it will cause entanglement and knotting of other cables.

[0007] Further, in the direction from the cylinder body to the driving rod, the depths of the grooves of the plurality of wire limiting openings gradually decrease.

[0008] Further, the cable fixing device in the pipeline further includes a wire fixing disk, which is arranged on the driving rod, and the first end of the third electric cylinder is connected to the wire fixing disk.

[0009] Furthermore, the hot-melt punching unit includes a first electric cylinder and a hot-melt punching rod of electric heating type disposed on the first electric cylinder. The first electric cylinder extends to insert the hot-melt punching rod of electric heating type into the side wall of the pipeline.

[0010] Furthermore, the cable fixing device in the pipeline further includes an adjusting electric cylinder disposed between the hot-melt punching unit and the cylinder block.

A plurality of wire fixing nails are sequentially arranged in the row of nail grooves along its length direction. A pushing plate is assembled in the row of nail grooves. One end of the guide rod is fixed on the connecting plate, and the other end of the guide rod passes through the pushing plate along the length direction of the row of nail grooves and extends to the outlet end of the row of nail grooves. The guide rod is slidably connected to the pushing plate. A pushing spring in a compressed and energy-stored state is sleeved outside the guide rod. Two ends of the pushing spring are respectively connected to the connecting plate and one end of the pushing plate far away from the nail driving part. The nail driving part includes a second electric cylinder connected to the traveling electric cylinder. A connecting seat is installed on the output rod of the second electric cylinder.

This case is suitable for the cable to be pre-passed through the pipeline, and is also suitable for the end of the cable to be fixed on the cable fixing device in the pipeline and gradually pass through the pipeline as the cable fixing device in the pipeline travels; thus, through multiple pairs of nail feeding parts, nail driving parts and wire limiting mechanisms, multiple cables can be synchronously fixed in the pipeline, and it is ensured that the cables are parallel to each other without crossing; in summary, the cable fixing device in the pipeline fixes the cable at a predetermined position in the pipeline, that is, the cable is parallel to the axis of the pipeline, and according to specific requirements, the part of the cable in the pipeline can be segmented and fixed to the inner wall of the pipeline, and the cable can be fixed on the inner wall of the pipeline or at a certain distance from the inner wall of the pipeline, so that multiple cables are in an orderly manner in the pipeline, avoiding the problem of entanglement and knotting.

[0036] As Figures 1 to 15 shown, in this embodiment, the cable fixing device in the pipeline includes: a traveling electric cylinder 100, a plurality of wire limiting mechanisms 600, a plurality of nailing parts 500, a plurality of hot melt punching units 300, and a storage battery 200. The traveling electric cylinder 100 includes a cylinder body and a driving rod 101. The plurality of wire limiting mechanisms 600 are arranged at intervals in the circumferential direction of the driving rod 101, and each wire limiting mechanism 600 is arranged to be telescopically movable in the radial direction of the driving rod 101. The plurality of nailing parts 500 are arranged at intervals in the circumferential direction of the cylinder body, and each wire limiting mechanism 600 is arranged to be telescopically movable in the radial direction of the cylinder body, and the plurality of nailing parts 500 and the plurality of wire limiting mechanisms 600 are arranged in one-to-one correspondence. The plurality of hot melt punching units 300 are arranged to be telescopically movable and at intervals in the circumferential direction of the cylinder body. The hot melt punching units 300 are located between the wire limiting mechanisms 600 and the nailing parts 500, and the plurality of hot melt punching units 300 and the plurality of nailing parts 500 are arranged in one-to-one correspondence; the storage battery 200 is arranged at the end of the cylinder body away from the driving rod 101, and the storage battery 200 supplies power to the traveling electric cylinder 100.

[0037] Applying the technical solution of this embodiment, the cable is pre-passed through the pipeline, and then the step-by-step traveling mechanism is arranged in the pipeline. The step-by-step traveling mechanism includes a traveling electric cylinder 100, and the driving rod 101 of the traveling electric cylinder 100 can telescopically move along the axial direction of the pipeline. The punching and fixing mechanism and the wire limiting mechanism 600 are respectively installed on the traveling electric cylinder 100 and the driving rod 101. The number of the punching and fixing mechanism and the wire limiting mechanism 600 is multiple and the same, and they are evenly arranged along the circumferential direction of the pipeline. The punching and fixing mechanism and the wire limiting mechanism 600 are arranged in pairs correspondingly, and each pair of the punching and fixing mechanism and the wire limiting mechanism 600 corresponds to one cable. A storage battery 200 is assembled on the traveling electric cylinder 100. The traveling electric cylinder 100, the punching and fixing mechanism and the wire limiting mechanism 600 are respectively connected to the PLC through wires, and the traveling electric cylinder 100, the punching and fixing mechanism and the wire limiting mechanism 600 are all electrically connected to the storage battery 200. The working principle and advantages of the present invention are as follows: The present invention can pre-pass the cable through the pipeline, and then straighten and fix it at a predetermined position in the pipeline through the equipment described in the present invention; the cable can also be fixed at the driving rod 101 of the traveling electric cylinder 100, and as the step-by-step traveling mechanism travels in the pipeline, the cable gradually passes through the pipeline; then, through the alternating travel of the driving rod 101 and the step-by-step traveling mechanism in the pipeline, and at the same time cooperating with the punching and fixing mechanism and the wire limiting mechanism 600, the cable is restricted, and the pipeline is punched and nailed, so that the fixing nail 900 is fixed on the inner wall of the pipeline, and the cable is located inside the fixing nail 900, and different models of fixing nails 900 can be selected according to specific situations; when the cable is pre-passed through the pipeline, the fixing nail 900 can tighten the corresponding part of the cable after binding, and generally in this case, the cable and the pipeline do not move relative to each other; in another case, when the cable is allowed to move in the pipeline after the fixing nail 900 is bound, the model of the fixing nail 900 is selected so that the cable is restricted by the fixing nail 900 after binding, but it does not affect the cable's movement in the pipeline under the pulling of an external force. This situation is suitable for the cable pre-passing through the pipeline, and is also suitable for the end of the cable being fixed to the step-by-step traveling mechanism and gradually passing through the pipeline as the step-by-step traveling mechanism travels; thus, through multiple pairs of punching and fixing mechanisms and wire limiting mechanisms 600, multiple cables can be synchronously fixed in the pipeline, and it is ensured that the cables are parallel to each other and do not cross; in summary, the present invention fixes the cable at a predetermined position in the pipeline, that is, the cable is parallel to the axis of the pipeline, and according to specific requirements, the part of the cable in the pipeline can be segmented and fixed to the inner wall of the pipeline, and the cable can be fixed on the inner wall of the pipeline or at a certain distance from the inner wall of the pipeline, so that multiple cables are in good order in the pipeline, avoiding the problem of entanglement and knotting.

[0038] Such as Figure 4As shown, in this embodiment, the punching and fixing mechanism includes a nail - driving and wire - fixing unit and a hot - melt punching unit 300. Among them, the nail - driving and wire - fixing unit and the hot - melt punching unit 300 are arranged at intervals along the traveling direction of the step - type traveling mechanism. The function of the hot - melt punching unit 300 is to perform hot - melt punching on the inner wall of the pipeline. The nail - driving and wire - fixing unit travels to the hot - melt punching position along with the traveling electric cylinder 100. Then, the end of the wire - fixing nail 900 is driven into the hot - melt hole channel and gradually solidifies to fix the wire - fixing nail 900 on the inner wall of the pipeline. At this time, the corresponding part of the wire - fixing nail 900 and the cable restricts the cable. The specific structure of the hot - melt punching unit 300 in this embodiment is as Figure 5 shown. The hot - melt punching unit 300 includes a first electric cylinder 301, a mounting plate 302, and two electro - thermal hot - melt punching rods 303. Among them, the mounting plate 302 is assembled on the output rod of the first electric cylinder 301, and the two electro - thermal hot - melt punching rods 303 are oppositely installed on the mounting plate 302. In this embodiment, in order to greatly improve the strength after the end of the wire - fixing nail 900 is connected to the inner wall of the pipeline, the upper parts of the two electro - thermal hot - melt punching rods 303 extend outward and upward. The wire - fixing nail 900 also has two ends that extend outward and upward. The two ends of the wire - fixing nail 900 are bound in two hot - melt holes, and the two hot - melt holes are respectively formed by hot - melting with the above - mentioned two electro - thermal hot - melt punching rods 303. Moreover, because the upper parts of the two electro - thermal hot - melt punching rods 303 in this embodiment extend outward and upward, it can effectively prevent the electro - thermal hot - melt punching rods 303 from contacting the cable and avoid scalding the cable. In this embodiment, in order to fully avoid the electro - thermal hot - melt punching rods 303 from scalding the cable when contacting the middle and lower positions of the cable, an insulating sheath 304 is sleeved below the middle of each electro - thermal hot - melt punching rod 303, and a channel is formed between the two insulating sheaths 304 for the cable to pass through. When positioning and fixing a cable in this embodiment, the nail - driving and wire - fixing units at other positions do not drive nails, that is, the wire - fixing nails 900 are taken out, and the hot - melt punching unit 300 is not powered on, but the hot - melt punching unit 300 and the nail - driving and wire - fixing unit can be driven to abut against the inner wall of the pipeline to realize the traveling of the traveling electric cylinder 100 in the pipeline.

[0039] As Figure 6 shown, in this embodiment, the nail - driving and wire - fixing unit includes a nail - feeding part 400 and a nail - driving part 500. Among them, the nail - feeding part 400 is connected to the cylinder body of the traveling electric cylinder 100 through a connecting plate 403, and the nail - driving part 500 is arranged at the end of the nail - feeding end of the nail - feeding part 400, and the nail - driving part 500 is connected to the cylinder body of the traveling electric cylinder 100. The specific structure of the nail - feeding part 400 in this embodiment is as Figure 7As shown, the nail feeding part 400 includes a nail row groove 401, which is connected to the connecting plate 403. The nail row groove 401 extends along the axial direction of the pipeline. A plurality of wire fixing nails 900 are sequentially arranged in the nail row groove 401 along its length direction. A push plate 402 is movably assembled in the nail row groove 401. One end of the guide rod 404 is fixed on the connecting plate 403; the other end of the guide rod 404 passes through the push plate 402 along the length direction of the nail row groove 401, and this end of the guide rod 404 extends to the outlet end of the nail row groove 401. The guide rod 404 is slidably connected to the push plate 402. In this embodiment, in order to make the push plate 402 always abut against the wire fixing nail 900 at the corresponding end, so that the wire fixing nails 900 located in the nail row groove 401 are kept tightly together, and to ensure that the wire fixing nails 900 are stably supplied to the nail driving part 500 one by one, the measure taken is that a pushing spring 405 is sleeved outside the guide rod 404. The pushing spring 405 is always in a compressed and elastic energy storage state, and the two ends of the pushing spring 405 are respectively connected to the connecting plate 403 and the end of the push plate 402 away from the nail driving part 500. In this embodiment, in order to prevent the push plate 402 from detaching from the end of the nail row groove 401 away from the nail driving part 500, a limiting stop edge 406 is constructed at the end of the nail row groove 401 away from the nail driving part 500. The limiting stop edge 406 extends towards the inside of the nail row groove 401, thereby realizing the limitation of the push plate 402, that is, when the push plate 402 is located at this position of the nail row groove 401, the edge of the push plate 402 is blocked by the limiting stop edge 406. In this embodiment, in order to facilitate the guiding of the cable and avoid the phenomenon of swinging, that is, to initially limit the cable, a wire passing groove 407 is constructed on the connecting plate 403 and at the end close to the inner wall of the pipeline, and the cable passes through the wire passing groove 407. The specific structure of the nail driving part 500 in this embodiment is as Figures 9 to 11As shown, the nailing part 500 includes a second electric cylinder 501, a baffle 503 and a nail placing part 506. Among them, the second electric cylinder 501 is connected to the cylinder body of the traveling electric cylinder 100. In this embodiment, a connecting seat 502 is installed on the output rod of the second electric cylinder 501. An assembly groove 504 is formed on one side of the baffle 503, and a strip hole 505 extending along the movement direction of the output rod of the second electric cylinder 501 is formed on the baffle 503. The connecting seat 502 is installed in the assembly groove 504, and the connecting seat 502 is connected and fixed to the baffle 503 by a bolt passing through the strip hole 505. In this embodiment, a nail placing part 506 is formed at the upper end of the baffle 503. The nail placing part 506 has a nail placing groove 507, and the wire fixing nail 900 is pushed into the nail placing groove 507. In this embodiment, the nail placing part 506 is a structure made of deformable metal material or polyethylene material, and the back plate 508 of the nail placing part 506 has a notch 509 for its deformation. The second electric cylinder 501 of this embodiment drives the nail placing part 506 to move towards the inner wall direction of the pipeline, so as to realize that the wire fixing nail 900 in the nail placing groove 507 is stapled on the inner wall of the pipeline. When the wire fixing nail 900 is fixed to the inner wall of the pipeline, the output rod of the second electric cylinder 501 returns to its original position. The nail placing part 506 deforms during the process of separating from the wire fixing nail 900, and realizes the separation of the two. Moreover, during the movement of the nail placing part 506, the baffle 503 always adheres to the nail outlet end of the nail feeding part 400, preventing the wire fixing nail 900 from coming out. As Figure 4 As shown, in order to adjust the distance between the hot melt punching unit 300 and the nail driving and wire fixing unit in this embodiment, and thus realize the adjustment of the nailing interval, an adjusting electric cylinder 800 is installed on the nail driving and wire fixing unit. The output rod of the adjusting electric cylinder 800 is connected to the hot melt punching unit 300, and the adjusting electric cylinder 800 is connected to the PLC and the storage battery 200. The driving direction of the adjusting electric cylinder 800 is the axial direction of the pipeline.

[0040] In order to facilitate the fixing or lifting of the cable and improve the fixing strength between the wire fixing nail 900 and the inner wall of the pipeline, as Figure 12As shown, in this embodiment, the wire fixing nail 900 includes a bottom rod 901, two wire tie rods 902 and two nail head rods 903, wherein the bottom rod 901 is a straight rod or a curved rod bent downward, the two wire tie rods 902 are respectively constructed at the two ends of the bottom rod 901, each wire tie rod 902 is bent upward and inward, each nail head rod 903 is constructed at the upper end of the wire tie rod 902, the nail head rod 903 is bent upward and outward, the connection between the wire tie rod 902 and the nail head rod 903 is a wire tie joint 904, and the bottom rod 901, the wire tie rod 902 and the nail head rod 903 are an integrally formed structure. Moreover, a wire tie opening 905 is formed between the bottom rod 901 and the two wire tie rods 902, and a wire locking opening 906 is formed between the two wire tie joints 904. Under the action of the nailing part 500, the two nail head rods 903 of the wire fixing nail 900 of this embodiment are respectively nailed into the corresponding hot melt holes and continuously pressed, so that the wire fixing nail 900 is deformed under the pressure of the nailing part 506, and then the two wire binding joints 904 gradually approach to achieve the sealing of the wire locking opening 906. At this time, the cable is located in the wire binding opening 905 and cannot escape from the sealed wire locking opening 906. According to different models of wire fixing nails 900, the cable can move in the wire binding opening 905 of the corresponding model of wire fixing nail 900 (in this case, the cable gradually passes through the pipeline together with the traveling electric cylinder 100), or the cable is tightened in the wire binding opening 905 of the corresponding model of wire fixing nail 900 (in this case, the cable passes through the pipeline in advance). The nail row slot 401 of this embodiment is adapted to the wire fixing nail 900. Due to the special structure of the wire fixing nail 900, no additional components are required in the nail row slot 401, so as to prevent the wire fixing nail 900 from being separated from the notch opened above the nail row slot 401. Figure 8 As shown, the nail row groove 401 includes a groove bottom 4012, two groove bottom walls 4011 and two groove top walls 4013. The two groove bottom walls 4011 are respectively constructed on both sides of the groove bottom 4012, and each groove top wall 4013 is respectively arranged at the upper end of the corresponding groove bottom wall 4011. The groove bottom wall 4011 extends upward and inward, and the groove top wall 4013 extends upward and outward, so that the above-mentioned wire fixing nail 900 is assembled in the nail row groove 401. In order to completely seal the wire locking port 906 in this embodiment to prevent the cable from escaping from the cable harness port 905, as shown in FIG. Figure 13 As shown, the wire tie rod 902 and nail head rod 903 on one side of the wire fixing nail 900 are staggered with the wire tie rod 902 and nail head rod 903 on the other side of the wire fixing nail 900, so that when the bottom rod 901 of the wire fixing nail 900 is pressed externally, the two wire tie joints 904 are close to each other and overlap, thereby achieving the purpose of complete sealing. In order to fasten the nail head rod 903 in the hot melt hole, the outer surface of each nail head rod 903 is covered with barbs.

[0041] like Figure 2 as well as Figures 14 to 15As shown, in this embodiment, a connecting flange 102 is constructed on the driving rod 101 of the traveling electric cylinder 100. A plurality of wire limiting mechanisms 600 are fixed on the fixed disk 700, and the fixed disk 700 is detachably installed on the connecting flange 102. Among them, the wire limiting mechanism 600 includes a third electric cylinder 601 and a limiting unit. The third electric cylinder 601 is installed on the outer peripheral wall of the fixed disk 700, and the limiting unit is installed on the output rod of the third electric cylinder 601. The limiting unit abuts against the inner wall of the pipeline under the drive of the third electric cylinder 601. In this embodiment, the limiting unit includes an assembly plate 602 and a plurality of wire limiting claws 603. The assembly plate 602 is connected to the output rod of the third electric cylinder 601, and the assembly plate 602 extends along the axial direction of the driving rod 101. A reinforcing rib 605 is constructed on the assembly plate 602. The above-mentioned plurality of wire limiting claws 603 are constructed on the end face of the assembly plate 602 away from the third electric cylinder 601, and these wire limiting claws 603 are arranged at intervals along the length direction of the assembly plate 602. In this embodiment, in order to limit the cable and prevent it from swinging, a wire limiting port 604 is constructed on the wire limiting claw 603. Among them, under the drive of the output rod of the third electric cylinder 601, the wire limiting claw 603 abuts against the inner wall of the pipeline. At this time, the cable is located in the wire limiting port 604 of these wire limiting claws 603, and at least one wire limiting port 604 tightly adheres the part of the cable to the inner wall of the pipeline, so that the cable will not have problems such as deviation and swinging.

[0042] The technical solution of this embodiment also discloses a method for a cable fixing device in a pipeline for using the cable fixing device in the pipeline, including the following steps:

[0043] S1. First, pass at least one cable into the pipeline, and the other end of the cable extends out of the pipeline, and straighten the cable; or there are rod bodies with the same number as the cables installed on the driving rod 101, and these rod bodies are arranged corresponding to the cables one by one. The rod bodies are used for tying the ends of the corresponding cables, and the relative position between the tied part of the cable and the inner wall of the pipeline is the position where the cable needs to be positioned, and fix one end of the cable on the driving rod 101;

[0044] S2. Place the traveling electric cylinder 100 in the pipeline, and ensure that the driving rod 101 is at the front end. Then, make the corresponding punching and fixing mechanism and the wire limiting mechanism 600 be arranged opposite to the cable at this position;

[0045] S3. Turn on the power switch. The wire limiting mechanism 600 restricts the corresponding cable until the wire limiting mechanism 600 abuts against the inner wall of the pipeline. Then, the punching and fixing mechanism operates to perform hot melting punching on the inner wall of the pipeline;

[0046] S4. After hot-melt punching, the punching and fixing mechanism returns to its original position after hot-melt punching. Then, the progressive electric cylinder 100 operates. Since the wire limiting mechanism 600 is clamped on the inner wall of the pipeline, the progressive electric cylinder 100 moves forward, and the punching and fixing mechanism moves to a predetermined distance, that is, the nail driving part 500 of the punching and fixing mechanism moves to the position of the previous hot-melt punching, and the hot-melt punching component of the punching and fixing mechanism moves forward to the position of the next pre-heated hot-melt punching;

[0047] S5. The progressive electric cylinder 100 stops operating. The punching and fixing mechanism performs hot-melt punching and nail driving operations on the inner wall of the pipeline, and connects the corresponding part of the telecommunication cable to the inner wall of the pipeline through the fixing nail 900. After this binding, the punching and fixing mechanism does not return to its original position, and the wire limiting mechanism 600 disengages from the pipeline and returns to its original position;

[0048] S6. Control the operation of the progressive electric cylinder 100. Since the punching and fixing mechanism is fixed to the inner wall of the pipeline, the driving rod 101 extends forward. Then, control the wire limiting mechanism 600 to abut against the inner wall of the pipeline, and the punching and fixing mechanism returns to its original position. Repeat the actions in step S4 to perform hot-melt punching and nail driving operations at the next position;

[0049] S7. Repeat the actions in S6 until the progressive electric cylinder 100 moves to the outlet of the pipeline.

[0050] Compared with the prior art, the technical solution of this embodiment has the following technical improvements: In the technical solution of this embodiment, the cable can be pre-passed through the pipeline, and then straightened and fixed at a predetermined position of the pipeline by the cable fixing device in the pipeline; alternatively, one end of the cable can be fixed on the driving rod 101 of the traveling electric cylinder 100. As the traveling electric cylinder 100 travels in the pipeline, the cable gradually passes through the pipeline; then, by the alternating travel of the driving rod 101 and the wire limiting mechanism 600 in the pipeline, and in cooperation with the nail feeding part 400, the nail driving part 500 and the wire limiting mechanism 600, the cable is restricted, and the pipeline is drilled and nailed, so that the wire fixing nail 900 is fixed on the inner wall of the pipeline, and the cable is located inside the wire fixing nail 900. Moreover, according to specific situations, different models of wire fixing nails 900 can be selected; when the cable is pre-passed through the pipeline, the wire fixing nail 900 can tighten the corresponding part of the cable after binding. In this case, generally, there is no relative movement between the cable and the pipeline; in another case, when the wire fixing nail 900 allows the cable to move in the pipeline after binding, the model of the wire fixing nail 900 is selected so that the cable is restricted by the wire fixing nail after binding, but it does not affect the cable's movement in the pipeline under the pulling of an external force. This case is suitable for the cable pre-passing through the pipeline, and is also suitable for the end of the cable being fixed on the cable fixing device in the pipeline and gradually passing through the pipeline as the cable fixing device in the pipeline travels; thus, through multiple pairs of the nail feeding part 400, the nail driving part 500 and the wire limiting mechanism 600, multiple cables can be synchronously fixed in the pipeline, and it is ensured that the cables are parallel to each other and do not intersect; in summary, the technical solution of this embodiment fixes the cable at a predetermined position in the pipeline, that is, the cable is parallel to the axis of the pipeline, and according to specific requirements, the part of the cable in the pipeline can be segmented and fixed to the inner wall of the pipeline, and the cable can be fixed on the inner wall of the pipeline or at a certain distance from the inner wall of the pipeline, so that multiple cables are in good order in the pipeline, avoiding the problem of entanglement and knotting.

[0051] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as limiting the protection scope of the present invention; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0052] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper" etc. may be used herein to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is inverted, a device described as "above" or "over" other devices or structures will then be positioned "below" or "beneath" the other devices or structures. Thus, the exemplary term "above" can include both orientations of "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the corresponding explanations for the spatial relative descriptions used herein will be made accordingly.

[0053] In addition, it should be noted that the use of terms such as "first", "second" etc. to define components is only for the convenience of differentiating the corresponding components. Without additional statements, the above terms have no special meanings, and thus should not be construed as limiting the protection scope of the present invention.
