Description

Technical Field

[0001] This invention belongs to the field of cable chain technology, and in particular relates to a cable chain cover plate installation structure and cable chain that are easy to disassemble and assemble. Background Technology

[0002] Cable chains are suitable for use in reciprocating motion applications, providing traction and protection for internal cables, oil pipes, air pipes, water pipes, etc., while also making the overall machine look more aesthetically pleasing. Cable chains are mostly composed of several links connected together in a rotatable manner. Each unit link consists of two chain plates and upper and lower cover plates, which form a channel through which cables, oil pipes, air pipes, water pipes, etc., are placed.

[0003] In the prior art, the upper and / or lower cover plates of cable chains are mostly connected to the two chain plates by a snap-fit ​​structure. This structure has the disadvantages of being inconvenient and time-consuming to disassemble the upper and / or lower cover plates. Summary of the Invention

[0004] The purpose of this invention is to provide a cable chain cover plate installation structure and cable chain that are easy to disassemble and assemble, so as to solve the problems of inconvenience and time and labor cost in disassembling the upper cover plate and / or lower cover plate of the cable chain in the prior art.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A cable chain cover mounting structure that is easy to assemble and disassemble includes two chain plates and a cover plate. At least one end of the cover plate is detachably mounted to the corresponding chain plate via a quick-release mechanism.

[0007] The quick-release mechanism includes a sliding assembly and a limiting assembly. The sliding assembly includes a sliding member and a locking member. The locking member is disposed on the sliding member. The sliding member is slidably mounted on the cover plate along the length direction of the cover plate. A locking groove is formed on the chain plate in cooperation with the locking member. The limiting assembly is configured to position the sliding member in a first position or a second position.

[0008] When the slider is in the first position, the locking member extends from the end of the cover plate and inserts into the corresponding locking groove to lock the end of the cover plate onto the corresponding chain plate.

[0009] When the slider is in the second position, the locking member retracts to the end of the cover plate and disengages from the locking groove, thereby releasing the lock between the end of the cover plate and the corresponding chain plate.

[0010] Furthermore, both ends of the cover plate are provided with limit heads, and limit grooves are opened on both chain plates in cooperation with the limit heads. A positioning boss is provided in the limit groove, and a positioning hole is opened on the limit head in cooperation with the positioning boss. The locking groove is opened on the inner side of the positioning boss.

[0011] Furthermore, both ends of the cover plate are provided with sliding grooves extending along the length direction of the cover plate. The sliding member can be slidably assembled in the sliding groove. The length of the sliding groove is greater than the length of the sliding member. The bottom of the sliding groove is provided with a through hole penetrating the end of the cover plate. The locking member passes through the through hole and is inserted into the corresponding locking groove.

[0012] Furthermore, the limiting component includes a first limiting member and a second limiting member. The first limiting member is disposed on the sliding member, and the second limiting member is disposed at the bottom of the slide groove, or the first limiting member is disposed at the bottom of the slide groove, and the second limiting member is disposed on the sliding member. The sliding member is positioned at the first position or the second position by the cooperation of the first limiting member and the second limiting member.

[0013] Furthermore, the first limiting member includes a limiting boss, and the second limiting member includes two elastic claws. One end of the two elastic claws is connected to the sliding member, and the other end is brought together to form an elastic latch. The width of the elastic latch is smaller than the width of the limiting boss. When the sliding member is in the first position, the side of the limiting boss near the end of the cover plate positions the sliding member. When the cover plate of the cable chain is removed, the sliding member is pushed to slide towards the center of the cover plate. The elastic latch is subjected to greater force and passes over the limiting boss. The side of the limiting boss away from the end of the cover plate positions the sliding member to position the sliding member in the second position.

[0014] Furthermore, the limiting boss is symmetrically provided with two first positioning slopes and two second positioning slopes, and the elastic latch is provided with two third positioning slopes and two fourth positioning slopes on both sides. When the sliding member is in the first position, the two first positioning slopes and the two third positioning slopes are tightly engaged to position the sliding member. When the cover plate of the cable chain is removed, the sliding member is pushed to slide towards the center of the cover plate of the cable chain. The elastic latch is subjected to increased force and returns to its original position after passing the two first positioning slopes. The two second positioning slopes and the two fourth positioning slopes are tightly engaged to position the sliding member in the second position.

[0015] Furthermore, the sliding member, the locking member, and the two elastic claws are integrally injection molded. The locking member is located below the sliding member, and one end of each of the two elastic claws is connected to the locking member. The locking member is connected to the sliding member through a connecting part.

[0016] Furthermore, the connecting part is eccentrically disposed on the sliding member and disposed on one side near the end of the cover plate. The locking member includes a locking head and a connecting plate. The locking head is connected to the connecting part through the connecting plate. The locking head is disposed at the head end of the connecting plate. The tail end of the connecting plate is provided with a limiting block extending between the two elastic claws. The thickness of the locking head is greater than the thickness of the connecting plate.

[0017] Furthermore, the cover plate is either the upper or lower cover plate of a unit link of the cable chain, and the cover plate is either a closed or open cover plate of a unit link of the cable chain.

[0018] A cable chain that is easy to assemble and disassemble includes several unit links connected together in a rotatable manner. Each unit link includes two chain plates, an upper cover plate, and a lower cover plate. The two ends of the upper cover plate and / or the lower cover plate are detachably mounted on the two chain plates through the aforementioned cable chain cover plate mounting structure.

[0019] The beneficial effects of this invention are that, compared with the prior art, the easily detachable cable chain cover installation structure connects the cover plate to the chain plate through a quick-release mechanism. This quick-release mechanism includes a sliding component and a limiting component. Locking and unlocking of the cover plate and chain plate are achieved by operating the sliding component. Not only is the structure simple, ingeniously designed, and easy to implement, but it also greatly improves the efficiency of cover plate assembly and disassembly while ensuring the reliability of the connection between the cover plate and the chain plate. Operation is simple, saving time and effort. Attached Figure Description

Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention. It should be noted that when a component is referred to as being "fixed to" another component, it can be directly on the other component or there may be an intermediate component. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or there may be an intermediate component. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0028] The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] Please see Figures 1 to 6As shown, in this embodiment, a cable chain cover plate mounting structure that is easy to assemble and disassemble includes two chain plates 1 and a cover plate 2. The two ends of the cover plate 2 are detachably mounted on the two chain plates 1 through a quick-release mechanism. The quick-release mechanism includes a sliding component 3 and a limiting component. The sliding component 3 includes a sliding member 30 and a locking member 31. The locking member 31 is disposed on the sliding member 30. The sliding member 30 is slidably assembled on the cover plate 2 along the length direction of the cover plate 2. A locking groove 10 is provided on the chain plate 1 in cooperation with the locking member 31. The limiting component is configured to position the sliding member 30 in a first position or a second position. The first position is the locking position of the cover plate 2 and the chain plate 1, and the second position is the unlocking position of the cover plate 2 and the chain plate 1. When the slider 30 is in the first position, the locking member 31 extends out of the end of the cover plate 2 and inserts into the locking groove 10 of the corresponding chain plate 1 to lock the end of the cover plate 2 onto the corresponding chain plate 1. When the slider 30 is in the second position, the locking member 31 retracts to the end of the cover plate 2 and disengages from the locking groove 10 to release the lock between the cover plate 2 and the corresponding chain plate 1.

[0030] As can be seen, by setting sliding components 3 at both ends of the cover plate 2 and opening locking grooves 10 on the inner side of the corresponding chain plates 1, after the sliding components 3 are assembled on the cover plate 2, the sliding component 30 is pushed to move closer to the same side chain plate 1, so that the locking component 31 is inserted into the locking groove 10 on the corresponding chain plate 1. At this time, the limiting component fixes the locking component 31 in the first position, so as to realize the quick installation of the cover plate 2. When disassembling, the sliding component 30 is pushed to move away from the same side chain plate 1, so that the locking component 31 is disengaged from the locking groove 10 on the corresponding chain plate 1. At this time, the limiting component fixes the locking component 31 in the second position, so as to realize the quick disassembly of the cover plate 2. Under the premise of ensuring the reliability of the connection between the cover plate and the chain plate, the disassembly and assembly efficiency of the cover plate is greatly improved, the operation is simple, and time and labor are saved.

[0031] As an optional implementation, square limiting heads 20 are provided at both ends of the cover plate 2. Square limiting grooves 11 are provided on both chain plates 1 in conjunction with the limiting heads 20. Square positioning bosses 12 are provided in the limiting grooves 11. Square positioning holes 21 are provided on the limiting heads 20 in conjunction with the positioning bosses 12. Locking grooves 10 are provided on the inner side of the positioning bosses 12.

[0032] As can be seen, by the cooperation of the limiting head 20 and the limiting groove 11, the end of the cover plate 2 can be completely embedded into the corresponding chain plate 1. At the same time, the setting of the positioning boss 12 and the positioning hole 21 can ensure the accuracy of the installation position of the cover plate 2 and the reliability of the connection, so as to realize the stable and reliable connection of the end of the cover plate 2 to the chain plate 1.

[0033] As an optional implementation, both ends of the cover plate 2 are provided with sliding grooves 22 extending along the length direction of the cover plate 2. The sliding grooves 22 are also provided with inner grooves 23. The sliding member 30 is slidably assembled in the sliding grooves 22. The length of the sliding grooves 22 is greater than the length of the sliding member 30. The bottom of the inner groove 23 is provided with a through hole 24 penetrating the end of the cover plate 2. The through hole 24 is connected to the positioning hole 21. The locking member 31 passes through the through hole 24 and is inserted into the corresponding locking groove 10. Preferably, the through hole 24 is a square hole, and the end of the locking member 31 that passes through the through hole 24 is also a square mechanism.

[0034] As can be seen, by setting the slide groove 22, the sliding member 30 is assembled in the slide groove 22, which can ensure the stability and reliability of the sliding member 30. The length of the slide groove 22 is greater than the length of the sliding member 30 so that the sliding member 30 can be in the first position and the second position. The inner groove 23 is used to provide assembly space for the locking member 31 and the limiting component. The through hole 24 and the locking member 31 are set as a square structure that cooperates with each other. When the locking member 31 passes through the through hole 24, the through hole 24 also has a guiding and limiting effect on the locking member 31 to ensure the stability and reliability of the sliding of the locking member 31.

[0035] As an optional implementation, the limiting component includes a first limiting member and a second limiting member. The first limiting member is disposed on the sliding member 30, and the second limiting member is disposed at the bottom of the slide groove 22, or the first limiting member is disposed at the bottom of the slide groove 22, and the second limiting member is disposed on the sliding member 30. The sliding member 30 is relatively fixed at a first position or a second position by the cooperation of the first limiting member and the second limiting member.

[0036] It can be seen that by cooperating with the first and second limiting members, the sliding member 30 is relatively fixed in the first or second position to achieve the locking and unlocking of the cover plate 2, providing a limiting component with a simple structure and easy implementation.

[0037] As an optional implementation, the first limiting member includes a limiting boss 4, and the second limiting member includes two elastic claws 5. One end of the two elastic claws 5 is connected to the sliding member 30, and the other end is brought together to form an elastic latch 50. The width of the elastic latch 50 is smaller than the width of the limiting boss 4. When the sliding member 30 is in the first position, the side of the limiting boss 4 near the end of the cover plate 2 positions the sliding member 30. When the cover plate 2 is removed, the sliding member 30 is pushed to slide towards the center of the cover plate 2. The elastic latch 50 is subjected to greater force and passes over the limiting boss 4. At this time, the side of the limiting boss 4 away from the end of the cover plate 2 positions the sliding member 30 to position the sliding member 30 in the second position.

[0038] As can be seen, by cooperating with the two ends of the limiting boss 4 and the elastic latch 5, the sliding member 30 is relatively fixed in the first position or the second position, providing a simple, reliable and stable first limiting member and second limiting member.

[0039] As an optional implementation, the limiting boss 4 is symmetrically provided with two first positioning slopes 40 and two second positioning slopes 41. The elastic latch 50 is provided with two third positioning slopes 51 and two fourth positioning slopes 52 on both sides respectively. When the sliding member 30 is in the first position, the two first positioning slopes 40 and the two third positioning slopes 51 are tightly fitted together to position the sliding member 30. When the cover plate 2 is removed, the sliding member 30 is pushed to slide towards the center of the cover plate 2. The elastic latch 50 is subjected to greater force and returns to its original position after passing over the two first positioning slopes 40. The two second positioning slopes 41 and the two fourth positioning slopes 52 are tightly fitted together to position the sliding member 30 in the second position.

[0040] It can be seen that the cooperation between the limiting boss 4 and the positioning inclined surface on the elastic latch 50 further improves the stability and reliability of the positioning of the sliding part 30.

[0041] As an optional implementation, the slider 30, the locking member 31 and the two elastic claws 5 are integrally injection molded. The locking member 31 is located below the slider 30, and one end of each of the two elastic claws 5 is connected to the locking member 31. The locking member 31 is connected to the slider 30 through the connecting part 32.

[0042] It is evident that by integrating the slider 30, locking member 31, and two elastic claws 5 into a single structure, a sliding assembly that is easy to manufacture and has low cost is provided. Of course, depending on actual needs, the slider 30, locking member 31, and two elastic claws 5 can also be designed as separate, detachable components.

[0043] As an optional implementation, the connecting part 32 is eccentrically disposed on the sliding member 30 and disposed on one side near the end of the cover plate 2. The locking member 31 includes a locking head 310 and a connecting plate 311. The locking head 310 is connected to the connecting part 32 through the connecting plate 311. The locking head 310 is disposed at the head end of the connecting plate 311. The tail end of the connecting plate 311 is provided with a limiting block 312 extending between the two elastic claws 5. The thickness of the locking head 310 is greater than the thickness of the connecting plate 311.

[0044] It can be seen that by setting the connecting part 32 eccentrically and setting the thickness of the connecting plate 311 to be less than the thickness of the locking head 310, the joint between the connecting plate 311 and the locking head 310 is more easily deformed, which facilitates the assembly and disassembly of the sliding member 30. At the same time, the setting of the limiting block 312 can limit the sliding member 30 on the outside when the sliding member 30 is in the second position, further improving the stability and reliability of the positioning of the sliding member 30.

[0045] When installing the slider 30, first align the locking head 310 with the through hole 24 and insert it, then push the entire slider 30 outward into the slide groove 22.

[0046] When disassembling the slider 30, since the slider 30 is in the first position, there is a gap 6 between the inner side of the slide groove 22 and the slider 30, which facilitates operation. The inner end of the slider 30 is lifted upward, so that the connection between the connecting plate 311 and the locking head 310 is deformed. Finally, the slider 30 can be pulled out of the slide groove 22 as a whole.

[0047] As an optional implementation, the cover plate 2 is either an upper cover plate or a lower cover plate of a unit link of the cable chain, and the cover plate 2 is either a closed cover plate or a non-closed cover plate of a unit link of the cable chain.

[0048] The specific disassembly and assembly process of the above-mentioned easy-to-disassemble cable chain cover installation structure is as follows:

[0049] During installation:

[0050] S1, first push the sliding parts 30 at both ends of the cover plate 2 to the second position.

[0051] S2, then install the limiting heads 20 at both ends of the cover plate 2 into the limiting grooves 11 of the chain plates 1 on both sides. The two ends of the cover plate 2 are positioned by the cooperation of the positioning bosses 12 and the positioning holes 21.

[0052] S3, finally push the sliding parts 30 at both ends of the cover plate 2 to the first position. At this time, the locking parts 31 of the two sliding parts 30 are inserted into the locking grooves 10 on the corresponding chain plates 1 to fix the cover plate 2 on the two chain plates 1 on both sides.

[0053] During disassembly:

[0054] S1, In the initial state, the sliding parts 30 at both ends of the cover plate 2 are in the first position. First, push the sliding parts 30 at both ends of the cover plate 2 to the second position. At this time, the locking parts 31 on the two sliding parts 30 disengage from the locking grooves 10 on the corresponding chain plates 1 so that the cover plate 2 is unlocked from the two chain plates 1 on both sides.

[0055] S2, then pull the cover plate 2 upwards to remove it from the two chain plates 1 on both sides.

[0056] The aforementioned easy-to-install cable chain cover plate installation structure greatly improves the efficiency of cover plate installation and removal while ensuring the reliability of the connection between the cover plate and the chain plate. It is simple to operate and saves time and effort.

Each unit link includes two chain plates, an upper cover plate, and a lower cover plate. The two ends of the upper cover plate and / or the lower cover plate are detachably mounted on the two chain plates through the aforementioned cable chain cover plate mounting structure.

[0058] The above embodiments merely illustrate the basic principles and characteristics of the present invention. The present invention is not limited to the above examples. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
