Description

Technical Field

[0001] This disclosure relates to the field of linear drive technology, and more specifically, to an interlocking chain and a chain interlocking device. Background Technology

[0002] Currently, commonly used linear drive devices mainly include circumferential drive mechanisms and linear motion mechanisms. The conversion of driving force between circumferential drive mechanisms and linear motion mechanisms is achieved through specific structures. Common linear motion mechanisms include interlocking first and second chains.

[0003] In this mechanism, the first and second chains are interlocked to form a linear motion mechanism, which can act as a support column to support the object to be supported, or it can be used for pulling or pushing actions. However, because the linear structure of the linear motion mechanism has weak resistance to bending and torsion, the support stability of the object to be supported is poor.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art.

The interlocking part is bent at the edge of the connecting part in a direction away from the opposite group of chain plates.

[0009] Multiple connectors connect the connecting parts of the first set of chain plates to the connecting parts of the second set of chain plates. Multiple chains are distributed circumferentially, and adjacent sets of chain plates can interlock or unlock, and after interlocking, they form a columnar hollow structure.

[0010] According to any of the interlocking chains described in this disclosure, the interlocking part is a planar structure, and the chain plates of the plurality of chains can form a hollow prism structure.

[0012] The first chain plate is located outside the second chain plate, and the angle formed by the connecting part and the interlocking part of the first chain plate is greater than the angle formed by the connecting part and the interlocking part of the second chain plate.

[0013] According to any of the interlocking chains described in this disclosure, after the plurality of chains are interlocked, the interlocking portion of the second chain plate is interlocked with the interlocking portion of a second chain plate of an adjacent chain and is coplanar, and the end of the interlocking portion of the first chain plate abuts against the interlocking portion of a second chain plate of an adjacent chain.

[0014] According to any of the interlocking chains described in this disclosure, after the multiple chains are interlocked, the interlocking portion of the first chain plate is interlocked with the interlocking portion of a first chain plate of an adjacent chain and is coplanar, and the end of the interlocking portion of the second chain plate abuts against the interlocking portion of a first chain plate of an adjacent chain.

[0015] According to any of the interlocking chains described in this disclosure, the interlocking chain comprises three chains, and the chain plates of the three chains interlock to form a hollow triangular prism structure.

[0016] According to any of the interlocking chains described in this disclosure, the interlocking chain comprises four chains, and the chain plates of the four chains interlock to form a hollow quadrangular prism structure.

[0017] According to any of the interlocking chains described in this disclosure, the interlocking part has an arc-shaped structure, and the chain plates of the plurality of chains can form a hollow cylindrical structure.

[0018] According to any of the interlocking chains described in this disclosure, the first set of chain plates includes alternating first chain plates and second chain plates;

[0019] The first chain plate is located outside the second chain plate, and the curvature of the interlocking part of the first chain plate is greater than the curvature of the interlocking part of the second chain plate.

[0020] According to any of the interlocking chains described in this disclosure, the interlocking part has a hook;

[0021] The number of chains is odd, and the hooks on the interlocking parts of the first set of chain plates face opposite directions to the hooks on the interlocking parts of the second set of chain plates.

[0022] According to another aspect of this disclosure, a chain interlocking device is provided, comprising a plurality of chain plate boxes and the interlocking chain described in the above aspect;

[0024] The embodiments disclosed herein include at least the following technical effects:

[0025] In this embodiment of the disclosure, for an interlocking chain comprising multiple chains, the interlocking portion of the chain plate on each chain is bent away from the opposite set of chain plates. Thus, the chain plates of each chain form an approximately "V"-shaped structure, allowing the interlocking of the chain plates of the multiple circumferentially distributed chains to create a columnar hollow structure. Compared to the linear motion mechanism mentioned in the prior art, the columnar hollow structure after interlocking in this embodiment of the disclosure has an increased cross-sectional size, thereby improving the supporting stability of the object to be supported. Furthermore, since the interlocking results in a columnar hollow structure, it is also possible to install cables or the like within the hollow channel, thereby improving the applicability of the interlocking chain.

[0044] Figure 1 A schematic diagram of the isolating structure of an interlocking chain 10 according to an embodiment of the present disclosure is shown. Figure 2 A top view of an interlocking chain 10 according to an embodiment of this disclosure is shown as an example. Figure 3 A schematic front view of a chain plate 111 according to an embodiment of the present disclosure is shown. Figure 4 A top view of a chain plate 111 according to an embodiment of this disclosure is illustrated. Figures 1-4 As shown, the interlocking chain 10 includes: multiple chains 1; each chain 1 includes a first set of chain plates 11 and a second set of chain plates 12 arranged opposite to each other, and multiple connectors 13; each of the first set of chain plates 11 and the second set of chain plates 12 includes multiple chain plates 111, each chain plate 111 including a connecting part 1111 and an interlocking part 1112, the interlocking part 1112 being bent at the edge of the connecting part 1111 in a direction away from the opposite set of chain plates; multiple connectors 13 connect the connecting part 1111 of the first set of chain plates 11 and the connecting part 1111 of the second set of chain plates 12, the multiple chains 1 are distributed circumferentially, and adjacent sets of chain plates can interlock or unlock, and after interlocking, they form a columnar hollow structure, i.e., a tubular structure.

[0045] In this embodiment of the disclosure, for the multiple chains 1 included in the interlocking chain 10, the interlocking portion 1112 of the chain plate 111 on each chain 1 is bent away from the opposite set of chain plates. Thus, the chain plate 111 of each chain 1 forms an approximately "V"-shaped structure, resulting in a columnar hollow structure after the chain plates 111 of the multiple circumferentially distributed chains 1 are interlocked. Compared to the linear motion mechanism mentioned in the prior art, the columnar hollow structure after interlocking in this embodiment of the disclosure has an increased cross-sectional size, thereby improving the support stability of the columnar hollow structure for the object to be supported. Furthermore, since the columnar hollow structure is formed after interlocking, cables and the like can be installed within the hollow channel, improving the applicability of the interlocking chain 10.

[0046] Among them, such as Figure 5 As shown, the interlocking chain 10 also includes a top cover 2, and one end of each of the multiple chains 1 is fixedly connected to the top cover 2. In this way, the locking ends of the multiple chains 1 are locked by the top cover 2 to prevent the multiple chains 1 from disengaging and unlocking each other, thereby increasing the stability of the interlocking chain 10.

[0047] In the embodiments of this disclosure, such as Figure 3 As shown, the interlocking part 1112 of the chain plate 111 has a hook 1113 so that two adjacent sets of chain plates of the plurality of chains 1 distributed in the circumferential direction can interlock when rolled out.

[0048] For example, taking the interlocking chain 10 as an example, which includes chains 1A, 1B and 1C distributed circumferentially, the latches 1113 of the first set of chain plates 11 of chain 1A are engaged with the latches 1113 of the second set of chain plates 12 of chain 1B, the latches 1113 of the first set of chain plates 11 of chain 1B are engaged with the latches 1113 of the second set of chain plates 12 of chain 1C, and the latches 1113 of the first set of chain plates 11 of chain 1C are engaged with the latches 1113 of the second set of chain plates 12 of chain 1A, thereby realizing the interlocking of chains 1A, 1B and 1C.

[0049] Optionally, the side of the hook 1113 of the interlocking part 1112 in the first set of chain plates 11 has a groove, and the side of the hook 1113 of the interlocking part 1112 in the second set of chain plates 12 has a protrusion that cooperates with the groove. In this way, when two adjacent sets of chain plates of multiple chains 1 are interlocked, the locking force of the chain plates 111 can be increased based on the cooperation of the groove and the protrusion, so as to ensure the torsional strength of the columnar hollow structure after interlocking, thereby improving the support stability of the object to be supported.

[0050] The chain plate 111 can be made of stainless steel, plastic, or ceramic materials, or with surface coating or a combination thereof, to adapt to working environments with high and low temperatures, high corrosion, and high cleanliness requirements. Furthermore, the chain plate 111 can be optimized through different manufacturing processes, local structural reinforcement, or weight reduction designs to improve its mechanical properties, achieving homogeneous or localized modification. For example, the manufacturing processes for the chain plate 111 can include widely used industrial processes such as sheet metal stamping, bending and welding, aluminum profile extrusion, precision casting and machining of metal alloys, injection molding or metal injection molding, and 3D printing. Local structural reinforcement of the chain plate 111 can be achieved through common surface treatments and heat treatments.

[0051] In this embodiment of the disclosure, the interlocking chain 10 includes at least three chains 1, that is, the interlocking chain 10 includes three or more chains 1.

[0052] Optionally, the interlocking chain 10 includes an odd number of chains 1. In this case, to ensure that the chain plates 111 of the odd number of chains 1 can interlock, for a single chain 1, such as Figure 5 As shown, the hooks 1113 on the interlocking part 1112 of the first set of chain plates 11 face away from the hooks 1113 on the interlocking part 1112 of the second set of chain plates 12.

[0053] Optionally, the number of chains 1 included in the interlocking chain 10 is even. In this case, in order to ensure that the chain plates 111 of the even number of chains 1 can interlock, for a chain 1, the hooks 1113 on the interlocking part 1112 in the first group of chain plates 11 face away from the hooks 1113 on the interlocking part 1112 in the second group of chain plates 12, or the hooks 1113 on the interlocking part 1112 in the first group of chain plates 11 face the same as the hooks 1113 on the interlocking part 1112 in the second group of chain plates 12.

[0054] In this embodiment of the disclosure, for each chain 1, as follows: Figure 6As shown, both the first group of chain plates 11 and the second group of chain plates 12 include alternating first chain plates 112 and second chain plates 113. In the first group of chain plates 11, the connecting portion 1111 of adjacent first chain plates 112 and the connecting portion 1111 of adjacent second chain plates 113 are connected to the first end of a connector 13. In the second group of chain plates 12, the connecting portion 1111 of adjacent first chain plates 112 and the connecting portion 1111 of adjacent second chain plates 113 are connected to the second end of a connector 13, and the connection is rotatable. Thus, each uninterlocked chain 1 can be coiled up to reduce the space occupied by the chain 1.

[0055] The structure of the first chain plate 112 can be the same as or different from that of the second chain plate 113. When the structure of the first chain plate 112 is the same as that of the second chain plate 113, after the chain plates 111 of multiple chains 1 interlock, the two first chain plates 112 and the two second chain plates 113 of different groups of adjacent chain plates, such as the first group of chain plates 11 of chain 1A and the second group of chain plates 12 of chain 1B, are completely locked together to increase the contact area during interlocking, thereby improving the support strength of the columnar hollow structure. For example, for adjacent chains 1A and 1B, after a first chain plate 112 in the first group of chain plates 11 of chain 1A is interlocked with a first chain plate 112 in the second group of chain plates 12 of chain 1B, their projections in the length direction of the columnar hollow structure completely coincide. And after a second chain plate 113 in the first group of chain plates 11 of chain 1A is interlocked with a second chain plate 113 in the second group of chain plates 12 of chain 1B, their projections in the length direction of the columnar hollow structure completely coincide.

[0056] When the structure of the first chain plate 112 is different from the structure of the second chain plate 113, such as Figure 7 As shown, in two adjacent sets of chain plates, such as the first set of chain plates 11 of chain 1A and the second set of chain plates 12 of chain 1B, two first chain plates 112 from different sets are completely locked together, and two second chain plates 113 from different sets are interleaved and abut against the two first chain plates 112 from different sets; or, in two adjacent sets of chain plates, two second chain plates 113 from different sets are completely locked together, and two first chain plates 112 from different sets are interleaved and abut against the two second chain plates 113 from different sets. In this way, while ensuring the supporting strength of the interlocked columnar hollow structure through the two completely locked chain plates 111, the mutual abutment of the first chain plates 112 and second chain plates 113 from different sets further increases the torsional strength of the columnar hollow structure.

[0057] For example, for adjacent chains 1A and 1B, after a first chain plate 112 of the first group of chain plates 11 in chain 1A interlocks with a first chain plate 112 of the second group of chain plates 12 in chain 1B, their projections along the length of the columnar hollow structure completely overlap. After a second chain plate 113 of the first group of chain plates 11 in chain 1A interlocks with a second chain plate 113 of the second group of chain plates 12 in chain 1B, their projections along the length of the columnar hollow structure form a cross structure. Furthermore, a second chain plate 113 of the first group of chain plates 11 in chain 1A abuts against a first chain plate 112 of the second group of chain plates 12 in chain 1B. A first chain plate 112 of the first group of chain plates 11 in chain 1A interlocks with a first chain plate 112 of the second group of chain plates 12 in chain 1B. Two chain plates 113 abut; or after one of the second chain plates 11 in the first group of chain plates 11 of chain 1A and one of the second chain plates 113 in the second group of chain plates 12 of chain 1B are interlocked, their projections in the length direction of the columnar hollow structure completely overlap; after one of the first chain plates 112 in the first group of chain plates 11 of chain 1A and one of the first chain plates 112 in the second group of chain plates 12 of chain 1B are interlocked, their projections in the length direction of the columnar hollow structure are intersecting; and one of the second chain plates 113 in the first group of chain plates 11 of chain 1A abuts with one of the first chain plates 112 in the second group of chain plates 12 of chain 1B, and one of the first chain plates 112 in the first group of chain plates 11 of chain 1A abuts with one of the second chain plates 113 in the second group of chain plates 12 of chain 1B.

[0058] In this embodiment of the disclosure, the interlocking part 1112 included in the chain plate 111 can be a planar structure or an arc-shaped structure. The planar structure and the arc-shaped structure of the interlocking part 1112 will be explained in detail below.

[0059] like Figure 4 As shown, when the interlocking part 1112 is a planar structure, the structure formed by the chain plates 111 of multiple chains 1 is a hollow prism structure.

[0060] Optionally, such as Figure 2 As shown, the interlocking chain 10 includes three chains 1, and the chain plates 111 of the three chains 1 interlock to form a hollow triangular prism structure; the interlocking chain 10 includes four chains 1, and the chain plates 111 of the four chains 1 interlock to form a hollow quadrangular prism structure.

[0061] For example, in the case of three chains 1, the angle formed by the connecting part 1111 and the interlocking part 1112 on the chain plate 111 is 150 degrees. At this time, the chain plates 111 of the three chains 1 interlock to form a hollow regular triangular prism structure. In the case of four chains 1, the angle formed by the connecting part 1111 and the interlocking part 1112 on the chain plate 111 is 135 degrees. At this time, the chain plates 111 of the four chains 1 interlock to form a hollow rectangular prism structure.

[0062] In light of the different structures of the first chain plate 112 and the second chain plate 113 described above, the first chain plate 112 is located outside the second chain plate 113, and the angle formed by the connecting part 1111 and the interlocking part 1112 of the first chain plate 112 is greater than the angle formed by the connecting part 1111 and the interlocking part 1112 of the second chain plate 113.

[0063] In conjunction with the above description, after multiple chains 1 are interlocked, the interlocking portion 1112 of the second chain plate 113 may be interlocked with the interlocking portion 1112 of a second chain plate 113 of an adjacent chain 1 and are coplanar, with the end of the interlocking portion 1112 of the first chain plate 112 abutting against the interlocking portion 1112 of a second chain plate 113 of an adjacent chain 1; or the interlocking portion 1112 of the first chain plate 112 may be interlocked with the interlocking portion 1112 of a first chain plate 112 of an adjacent chain 1 and are coplanar, with the end of the interlocking portion 1112 of the second chain plate 113 abutting against the interlocking portion 1112 of a first chain plate 112 of an adjacent chain 1. For specific examples, please refer to the above examples, which will not be repeated here.

[0064] When the interlocking part 1112 is an arc-shaped structure, the chain plates 111 of the multiple chains 1 form a hollow cylindrical structure or a hollow elliptical cylindrical structure.

[0065] For example, the interlocking chain 10 includes four chains 1, and the interlocking part 1112 on the chain plate 111 has a 1 / 4 arc-shaped structure with a hook 1113. At this time, the chain plates 111 of the four chains 1 interlock to form a hollow cylindrical structure.

[0066] In light of the aforementioned differences in structure between the first chain plate 112 and the second chain plate 113, the first chain plate 112 is located outside the second chain plate 113, and the curvature of the interlocking portion 1112 of the first chain plate 112 is greater than the curvature of the interlocking portion 1112 of the second chain plate 113.

[0067] In conjunction with the above description, after multiple chains 1 are interlocked, the interlocking portion 1112 of the second chain plate 113 may be interlocked with the interlocking portion 1112 of a second chain plate 113 of an adjacent chain 1 and are coplanar, with the end of the interlocking portion 1112 of the first chain plate 112 abutting against the interlocking portion 1112 of a second chain plate 113 of an adjacent chain 1; or the interlocking portion 1112 of the first chain plate 112 may be interlocked with the interlocking portion 1112 of a first chain plate 112 of an adjacent chain 1 and are coplanar, with the end of the interlocking portion 1112 of the second chain plate 113 abutting against the interlocking portion 1112 of a first chain plate 112 of an adjacent chain 1. For specific examples, please refer to the above examples, which will not be repeated here.

[0068] This disclosure also provides a chain interlocking device, including multiple chain plate boxes and the interlocking chain 10 described in the above embodiments.

[0069] Multiple chain plates 111 correspond one-to-one with multiple chains 1. The chains 1 are housed in the corresponding chain plate boxes and can be wound in or out. The multiple chain plate boxes are distributed circumferentially, and the multiple chains 1 can interlock when wound out of the corresponding chain plate boxes.

[0070] Thus, the multiple chains 1 wound out by the chain interlocking device can be interlocked to form a columnar hollow structure, thereby improving the stability of the support; in addition, due to the formed hollow channel, it is convenient to pass through the objects to be assembled, such as cables, to protect the objects to be assembled.

[0071] The chain plate box has a guide groove, within which the chain 1 is located. The guide groove's positioning function improves the stability of the chain 1's movement within the chain plate box. The chain 1 can be wound and housed within the chain plate box, meaning the guide groove is helical, thus reducing the chain plate box's volume. A sprocket is installed within the chain plate box, and the chain 1 housed within it meshes with the sprocket, causing the chain 1 to wind into or out of the chain plate box when the sprocket rotates. The sprocket's drive mechanism can be a motor drive.

[0072] The chain interlocking device also includes a top cover 2. One end of each of the multiple chains 1 extends out of the corresponding chain plate box and is fixedly connected to the top cover 2. In this way, when the multiple chains 1 are wound out of the corresponding chain plate box, they can move stably in a straight line. Due to the constraint of the top cover 2, their top ends will not bend outward to unlock. Furthermore, the top cover 2 makes it easier to increase the support area of ​​the object to be supported after the multiple chains 1 are interlocked, thereby improving the stability of the support.

[0073] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the appended claims.
