Description

Technical Field

[0001] This utility model relates to the field of dustproof cable chain technology, specifically a dustproof cable chain. Background Technology

[0002] Cable protection is crucial in industrial automated production and the operation of various mechanical equipment. Cable chains, as a device for protecting and guiding cables, are widely used, such as the cleanroom cable chain with a keel disclosed in application number CN202220740406.3.

[0003] Existing cable chains have several problems in practical use. Firstly, the sealing performance between the upper and lower covers is inadequate. In dusty or harsh working environments, dust, debris, and other impurities can easily enter the cable chain, damaging the cables, affecting their lifespan and signal transmission stability, and consequently impacting the normal operation of the equipment. Secondly, the connection between the upper and lower covers is not robust enough. During the frequent reciprocating motion of the cable chain, loosening can easily occur, reducing the overall reliability of the cable chain structure. Furthermore, traditional connection methods are not smooth enough during the closing operation, affecting assembly efficiency.

[0004] In summary, existing cable chains have shortcomings in terms of sealing performance, connection stability, and ease of closing. There is an urgent need for a new type of cable chain structure to solve these problems and meet the higher requirements for cable protection in industrial production. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a dustproof cable chain.

[0006] The technical solution adopted by this utility model is: a dustproof cable chain, including an upper cover and a lower cover. After the upper cover and the lower cover are closed, a cavity for cable passage is formed between the upper cover and the lower cover. Both sides of the upper cover and the lower cover are provided with connecting parts. Several chain teeth are equally spaced on the end face of the connecting parts. The chain teeth are provided with tooth grooves that can mesh with each other.

[0007] Furthermore, the chain tooth includes a first inclined surface, a first vertical surface, a first horizontal surface, a second vertical surface, a second inclined surface, and a second horizontal surface. The first inclined surface is connected to the end face of the connecting part. The end face of the connecting part and the first inclined surface, the first inclined surface and the first vertical surface, the first vertical surface and the first horizontal surface, the first horizontal surface and the second vertical surface, the second vertical surface and the second inclined surface, and the second inclined surface and the second horizontal surface are smoothly transitioned by rounded corners.

[0008] Furthermore, the cross-sections of the chain teeth and the tooth sockets are the same, and the chain teeth form tooth sockets that interlock with each other.

[0009] Furthermore, the height of the chain teeth is 1.2-2.5mm.

[0010] Furthermore, the spacing between the chain teeth is 4.5-6.5 mm.

[0011] Furthermore, both the upper and lower covers have a wave structure, wherein the upper cover has anti-roll baffles extending to both sides of the wave crest.

[0012] Furthermore, there are two anti-roll baffles, which are spaced apart at both ends of the crest of the upper cover.

[0013] Furthermore, the chain teeth include inclined plane three, inclined plane four, inclined plane five, horizontal plane three and horizontal plane four. The horizontal plane three and inclined plane three, as well as the horizontal plane four and inclined plane five, are smoothly transitioned by rounded corners. The included angle α formed between inclined plane three and inclined plane four is smaller than the included angle b formed between inclined plane four and inclined plane five.

[0014] Furthermore, the included angle a is 100-120°, and the included angle b is 115-140°.

[0015] The beneficial effects of this utility model are:

[0016] 1. Enhanced Sealing Performance: The teeth and grooves on both sides of the upper and lower covers of this dustproof cable chain interlock, forming a tight seal between the connecting parts of the upper and lower covers. In dusty or harsh working environments, this effectively prevents dust, debris, and other impurities from entering the cable chain, providing reliable protection for the cables, greatly extending their service life, ensuring the stability of signal transmission, and thus guaranteeing the continuous normal operation of the equipment.

[0017] 2. Enhanced connection stability: The interlocking design of the chain teeth and tooth grooves makes the connection between the upper and lower covers more secure. Even under frequent reciprocating motion of the cable chain, loosening is less likely to occur, improving the overall reliability of the cable chain structure, reducing the risk of equipment failure due to loose connections, and reducing maintenance costs and downtime.

[0018] 3. Optimized Closing Operation Ease: The design of the chain teeth and grooves makes the closing process of the upper and lower covers as smooth as a zipper. This not only improves assembly efficiency and reduces time and labor costs during the assembly process, but also makes it easier and faster to open and close the cable chain when maintenance or replacement of the internal cables is required later, enhancing operational convenience and flexibility.

[0019] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The utility model will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0028] This utility model provides a dustproof cable chain.

[0029] In this embodiment, refer to Figure 1-5 The dustproof cable chain includes an upper cover 1 and a lower cover 2. When the upper cover 1 and the lower cover 2 are closed, a cavity 3 is formed between the upper cover and the lower cover for the cable to pass through. Both sides of the upper cover 1 and the lower cover 2 are provided with connecting parts 4. Several chain teeth 5 are provided at equal intervals on the end face of the connecting parts 4. The chain teeth 5 are provided with tooth grooves 6 that can mesh with each other.

[0030] In the above technical solution, connecting parts are provided on both sides of the upper and lower covers, and the teeth and grooves on the connecting parts are designed to interlock (the teeth of the upper cover connecting part and the groove of the lower cover connecting part are pressed together, and the groove of the upper cover connecting part and the teeth of the lower cover connecting part are also pressed together). After interlocking, the connecting parts fit together to form a seal, which greatly improves the sealing performance of the cable chain, effectively preventing dust, debris and other impurities from entering the cable chain and protecting the cable. At the same time, it makes the fastening connection of the upper and lower covers more stable and less prone to loosening when the cable chain moves back and forth frequently. It also optimizes the closing operation, making it as smooth as a zipper.

[0031] Example 1 of chain teeth: The chain teeth include a first inclined surface 7, a first vertical surface 8, a first horizontal surface 9, a second vertical surface 10, a second inclined surface 11, and a second horizontal surface 12. The first inclined surface is connected to the end face of the connecting part. The end face of the connecting part and the first inclined surface, the first inclined surface and the first vertical surface, the first vertical surface and the first horizontal surface, the first horizontal surface and the second vertical surface, the second vertical surface and the second inclined surface, and the second inclined surface and the second horizontal surface are smoothly transitioned by a rounded corner 13.

[0032] In Example 1 of the chain teeth, the surfaces of the chain teeth are smoothly transitioned by rounded corners. On the one hand, this reduces stress concentration points, improves the structural strength and durability of the chain teeth, and extends their service life. On the other hand, when the chain teeth and tooth sockets mesh together, they can be more smoothly engaged, further improving the ease of engagement and disengagement and reducing operational resistance.

[0033] Specifically, the cross-sections of the chain teeth and the tooth sockets are the same, and the chain teeth form tooth sockets that interlock with each other.

[0034] In the above technical solution, the cross-sections of the chain teeth and the tooth grooves are the same, and the chain teeth can form interlocking tooth grooves, ensuring a tight fit between the two. This not only further enhances the sealing effect and prevents the entry of fine impurities, but also makes the upper and lower covers more evenly stressed during connection, improving the stability and reliability of the connection.

[0035] Specifically, the height of the chain teeth is 1.2-2.5mm.

[0036] In the above technical solution, the chain tooth height is 1.5-2.5mm. This size can ensure that the chain tooth and the tooth socket can effectively bite together, providing sufficient connection strength and sealing performance, without causing structural complexity and increased cost due to excessively high chain teeth, and also avoid affecting the biting effect and overall performance due to excessively low chain teeth.

[0037] Specifically, the spacing between the chain teeth is 4.5-6.5mm.

[0038] In the above technical solution, the spacing between the chain teeth is 4.5-5.5mm, which ensures the rationality of the chain tooth distribution. While ensuring that the chain teeth and tooth grooves can mesh tightly, it avoids the increased processing difficulty and cost caused by the chain tooth spacing being too small, and also prevents the connection stability and sealing effect from being reduced by the spacing being too large.

[0039] Specifically, both the upper cover 1 and the lower cover 2 have a wave structure, wherein the upper cover 1 has anti-rolling baffles 14 extending to both sides of the wave crest.

[0040] In the above technical solution, the upper and lower covers adopt a wave structure, which increases the flexibility of the cable chain, making it more flexible when bending and adapting to different installation environments and movement trajectories; the anti-rolling baffles extending to both sides on the crest of the upper cover effectively prevent the upper cover from curling and deforming during use, ensuring the normal operation of the cable chain and effective protection of the cable.

[0041] Specifically, there are two anti-roll baffles, which are spaced apart at both ends of the crest of the upper cover.

[0042] In the above technical solution, the two anti-rolling baffles, spaced apart on both sides of the crest of the upper cover, are symmetrically distributed and can better support the upper cover and prevent it from rolling, thus enhancing the anti-rolling effect.

[0043] Example 2 of chain tooth: The chain tooth includes inclined surface 3 15, inclined surface 4 16, inclined surface 5 17, horizontal surface 3 18 and horizontal surface 4 19. The horizontal surface 3 and inclined surface 3, as well as the horizontal surface 4 and inclined surface 5, are smoothly transitioned by rounded corners. The included angle 'a' formed by inclined surface 3 and inclined surface 4 is smaller than the included angle 'b' formed by inclined surface 4 and inclined surface 5. The included angle 'a' is 100-120°, and the included angle 'b' is 115-140°.

[0044] In embodiment 2 of the chain teeth, the difference between embodiment 2 and embodiment 1 of the chain teeth is that the middle slope no longer uses a rounded transition, but adopts a sharp angle structure, such as angle a and angle b. This structure can further improve the connection stability of the upper and lower covers.

[0045] Please note to all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
