Description

Technical Field

[0001] The utility model relates to the technical field of drag chains, in particular to a clamp seat and a flat drag chain cable module. Background Art

[0002] A drag chain is a device used for cables or pipelines that need to make reciprocating motions, and it plays a role of traction and protection. Flat drag chain cable modules are widely used because of their light weight and ease of movement and operation of automated equipment. Flat drag chain cable modules usually include a cable module and a chuck seat at both ends of the cable module, and the chuck seat is used to connect the cable module to external electrical components. Due to the need for reciprocating motion of the flat drag chain cable module, the cable module needs to be bent, and the bent cable module forms an upper parallel section and a lower parallel section parallel to its direction of motion, and an arc section is formed between the upper parallel section and the lower parallel section. However, during the movement of the existing flat drag chain cable module, the chuck seat at the end of the upper parallel section cannot well limit the position of the cable module, causing the portion of the upper parallel section close to the arc section to warp or tilt, affecting the service life of the flat drag chain cable module. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings, the purpose of the utility model is to provide a clamping seat and a flat drag chain cable module, which can limit the position of the cable module and prevent the cable module from warping and deflecting during movement.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is: a chuck seat, fixed at the end of the cable module, the cable module includes an upper parallel section, a lower parallel section and an arc section between the upper parallel section and the lower parallel section, the chuck seat is fixed at the end of the upper parallel section, the chuck seat includes an upper cover plate and a lower cover plate, the cable module is clamped between the upper cover plate and the lower cover plate, the chuck seat also includes a wire pressing part, and the wire pressing part includes:

[0005] A wire pressing plate, wherein the lower pressing plate extends along the edge of the upper cover plate close to the arc segment toward the movement direction of the cable module;

[0006] The limiting plates are provided with two limiting plates, and the limiting plates extend along the wire pressing plate toward the direction close to the cable module, and the cable module is limited between the two limiting plates.

[0007] The beneficial effect of the utility model is that the utility model finds that the upper parallel section is prone to upward warping and offset at a position close to the arc section, so the clamping head seat adds a wire pressing part, and the wire pressing plate of the wire pressing part is located above the cable module to prevent the cable module from warping upward when moving to the arc section. At the same time, two limit plates limit the position of the cable module in the width direction of the cable module to prevent the cable module from offsetting in the width direction of the cable module during movement.

[0008] Furthermore, the length of the wire pressing plate in the moving direction of the cable module is not greater than the radius of the arc segment, and the wire pressing plate and the limiting plate are flush at the end close to the arc segment.

[0009] The length of the wire pressing plate and the limit plate in the moving direction of the cable module should not be too long, otherwise it will cause interference when the chuck seat approaches the arc section.

[0010] Specifically, the vertical distance between the two limiting plates is equal to the width of the cable module, so that the cable module is limited between the two limiting plates. The length of each limiting plate in the vertical direction is not less than the thickness of the cable module, so that part of the cable module can be completely located between the two limiting plates and will not protrude from the limiting plates in the vertical direction. The two limiting plates can provide stable support for the cable module located therebetween.

[0011] Furthermore, the wire pressing part and the upper cover plate are integrally formed, which is convenient for processing.

[0012] Furthermore, the upper cover plate includes an upper plane that abuts against the upper end surface of the cable module, the wire pressing plate includes an upper pressing surface, the upper pressing surface and the upper plane are located at the same height, and the limit plate extends downward along the upper pressing surface, so as to ensure that the cable module extending out of the upper cover plate can be directly limited in height by the upper pressing surface without warping upward.

[0013] The utility model also discloses a flat drag chain cable module, comprising:

[0014] A cable module, wherein at least one cable module is provided, and the cable module comprises an upper parallel section, a lower parallel section and an arc section therebetween which are parallel to the direction of movement thereof;

[0015] a first chuck seat, the first chuck seat being fixed to an end of the lower parallel section;

[0016] A second chuck seat, wherein the second chuck seat is fixed to the end of the upper parallel section, and the second chuck seat adopts the above-mentioned chuck seat.

[0017] Since the cable module near the arc section of the upper parallel section is prone to warping upward, a wire pressing part is added to the upper cover of the second clamp seat, that is, a wire pressing plate is extended to control the tail warping. Limit plates extend downward on both sides of the wire pressing plate to prevent the entire cable module from separating and deviating.

[0018] Further, the cable module includes a first cable assembly and a second cable assembly arranged vertically, the first cable assembly and the second cable assembly being parallel;

[0019] The first cable assembly and the second cable assembly each include a protective sleeve and a plurality of cable bodies arranged side by side in the protective sleeve.

[0020] The first cable body is a signal line, the second cable body is a power line, and the diameter of the second cable body is larger than the diameter of the first cable body. At this time, the second cable assembly plays a supporting role.

[0021] Furthermore, the cable module further comprises an air pipe assembly, the air pipe assembly is parallel to the second cable assembly and is distributed above and below the second cable assembly;

[0022] The trachea assembly comprises a trachea sleeve and a plurality of trachea bodies arranged side by side in the trachea sleeve.

[0023] The cable module integrates the trachea assembly, and the trachea body can be used as a support. In addition to playing a ventilation role, it can also act as a keel.

[0024] Furthermore, the chuck seat further comprises a partition, which divides the clamping cavity into two cavities that are distributed up and down and are not connected, wherein the first cable assembly and the second cable assembly are located in one cavity, and the air pipe assembly is located in the other cavity. The air pipe assembly will not cause interference with the first cable assembly and the second cable assembly.

[0025] Furthermore, the plurality of cable modules are arranged side by side in the width direction. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0040] Embodiment 1

[0041] See attached Figure 1 As shown, the cable module 1 needs to be bent during use to form an upper parallel section 1a and a lower parallel section 1b parallel to its movement direction, and an arc section 1c is formed between the upper parallel section 1a and the lower parallel section 1b. A clamping seat 2 of the utility model is connected to the end of the upper parallel section 1a of the cable module 1 and is used to connect the cable module 1 and an external electrical device.

[0042] See attached Figure 2 As shown, the clamping head seat 2 includes an upper cover plate 21 and a lower cover plate 22, and the cable module 1 is clamped between the upper cover plate 21 and the lower cover plate 22. The upper cover plate 21 and the lower cover plate 22 are detachably connected. When the two are fixed, a clamping cavity 23 is formed. The clamping cavity 23 has openings at both ends along the moving direction (X direction) of the cable module 1. The cable module 1 is inserted into the clamping cavity 23 from one opening and is limited in the clamping cavity 23.

[0043] See attached Figure 2 As shown, the upper cover plate 21 and the lower cover plate 22 are symmetrically arranged in the vertical direction (Z direction), that is, the projection of the upper cover plate 21 on the lower cover plate 22 coincides with the lower cover plate 22. The upper cover plate 21 and the lower cover plate 22 are both square structures, and the clamping cavity 23 formed by the two is also a square structure.

[0044] In one embodiment, the clamp seat 2 further includes a wire pressing portion 24, and the wire-line portion includes a wire pressing plate 241 and two limit plates 242, the wire pressing plate 241 extends along the edge of the upper cover plate 21 close to the arc segment 1c toward the moving direction of the cable module 1, and the wire pressing plate 241 is located above the cable module 1. The two limit plates 242 are located on both sides of the wire pressing plate 241 in the Y direction and extend in the Z direction, and the cable module 1 is limited between the two limit plates 242.

[0045] The existing chuck seat 2 only has an upper cover plate 21 and a lower cover plate 22 in a square structure. When the cable module 1 moves to the arc segment 1c, the upper parallel section 1a is close to the arc segment 1c and is prone to warping upward, affecting the regularity of the cable module 1. At the same time, because the cable module 1 is only fixed by the chuck seat 2 at the end, it will also be offset in the width direction (Y direction) of the cable module 1. In this embodiment, it is precisely discovered that the upper parallel section 1a is prone to upward warping and offset at a position close to the arc segment 1c, so the chuck seat 2 adds a wire pressing portion 24, and the wire pressing plate 241 of the wire pressing portion 24 is located above the cable module 1 to prevent the cable module 1 from warping upward when it moves to the arc segment 1c. At the same time, the two limit plates 242 limit the position of the cable module 1 in the Y direction to prevent the cable module 1 from offsetting in the Y direction during movement.

[0046] In one embodiment, the vertical distance between the two limiting plates 242 is equal to or slightly greater than the width of the cable module 1, and the length of each limiting plate 242 in the Z direction is not less than the thickness of the cable module 1 in the Z direction. At this time, it is ensured that part of the cable module 1 can be completely located between the two limiting plates 242, and will not protrude from the limiting plates 242 in the Z direction. The two limiting plates 242 can provide stable support for the cable module 1 located therebetween.

[0047] Because the cable module 1 will only bend upward near the arc segment 1c, only a wire pressing plate is required. Figure 1 As shown, the length H of the wire pressing plate in the direction of movement of the cable module 1 is not greater than the radius R of the arc segment 1c, and the wire pressing plate and the stop plate 242 are flush at the end close to the arc segment 1c. The length H of the wire pressing plate and the stop plate 242 in the X direction should not be too long, otherwise it will cause interference when the chuck seat 2 is close to the arc segment 1c. Therefore, when setting the wire pressing plate, the length of the wire pressing plate in the X direction needs to be designed to be less than the radius R.

[0048] In one embodiment, according to the use requirements, the length H is 5-10 mm smaller than the radius R, which can both satisfy the position limitation of the cable module 1 and not hinder the movement of the cable module 1 .

[0049] In one embodiment, see the attached Figure 3As shown, the upper cover plate 21 includes a horizontal plate 211, and the horizontal plate 211 has an upper plane 211a that abuts against the upper end surface of the cable module 1. Two vertical plates 212 extend downward from both ends of the upper plane 211a in the Y direction. The vertical plates 212 of the upper cover plate 21 and the lower cover plate 22 can abut against each other, and a clamping cavity 23 corresponding to the cable module 1 is formed between the upper cover plate 21 and the lower cover plate 22.

[0050] In one embodiment, the wire pressing plate has an upper pressing surface 241a, which is located at the same height as the upper plane 211a, and the upper pressing surface 241a also abuts against the upper end surface of the cable module 1. The upper plane 211a and the upper pressing surface 241a are located at the same height, ensuring that the cable module 1 extending out of the upper cover plate 21 can be directly limited in height by the upper pressing surface 241a without warping upward.

[0051] In one embodiment, the upper cover plate 21 and the wire pressing part 24 are an integrated structure, that is, the upper cover plate 21 is directly provided with a wire pressing plate 241 along the X direction. The upper cover plate 21 and the wire pressing part 24 form an upper movable plate structure.

[0052] However, in one embodiment, the lower cover plate 22 and the wire pressing portion 24 may also be separate structures, and the wire pressing portion 24 and the upper cover plate 21 are detachably connected by bolts.

[0053] The clamp seat 2 in this embodiment limits the cable module 1 by adding a wire pressing portion 24. The wire pressing plate presses the cable module 1 downward to prevent the cable module 1 from warping upward. The limiting plate 242 limits the position of the cable module 1 in the width direction of the cable module 1 to prevent the cable module 1 from shifting during movement.

[0054] Embodiment 2

[0055] See attached Figure 6 As shown, the flat drag chain cable module of this embodiment includes a cable module 1 and a first chuck seat 3 and a second chuck seat located at the ends of all cable modules 1. The cable module 1 needs to be bent during use to form an upper parallel section 1a and a lower parallel section 1b parallel to its movement direction, and an arc section 1c is formed between the upper parallel section 1a and the lower parallel section 1b. The first chuck seat 3 is fixed to the end of the lower parallel section 1b, and the second chuck seat is fixed to the end of the upper parallel section 1a. The second chuck seat adopts the chuck seat 2 in the first embodiment.

[0056] The first clamping seat 3 is fixed, and the second clamping seat moves synchronously during the movement of the cable module 1 .

[0057] In this embodiment, since the cable module 1 of the upper parallel section 1a close to the arc section 1c is prone to warp upward, the upper cover plate 21 of the second clamping seat is increased with a wire pressing portion 24, that is, it is extended to form a wire pressing plate to control the warping. The two sides of the wire pressing plate extend downward with limit plates 242 to prevent the entire cable module 1 from separating and deviating.

[0058] In this embodiment, the first chuck seat 3 is not provided with a wire pressing portion 24 and is a rectangular parallelepiped as a whole.

[0059] The cable module includes a plurality of cable assemblies arranged in the vertical direction, each of which includes a protective sleeve and a cable body arranged in the protective sleeve along the Y direction. Each cable assembly forms a flat cable arrangement to reduce the movement resistance of the drag chain.

[0060] In one embodiment, see the attached Figure 6 The cable module 1 includes a first cable assembly 11 and a second cable assembly 12 arranged vertically, the first cable assembly 11 and the second cable assembly 12 are parallel, and since the cable module 1 may be bent, the second cable assembly 12 is always located outside the first cable assembly 11. The first cable assembly 11 includes a plurality of first cable bodies distributed along the Y direction, and all first cable bodies are fixed in the first protective sleeve. The second cable assembly 12 includes a plurality of second cable bodies distributed along the Y direction, and all second cable bodies are fixed in the second protective sleeve.

[0061] In this embodiment, the first cable body is a signal line, the second cable body is a power line, and the diameter of the second cable body is greater than the diameter of the first cable body. At this time, the second cable assembly 12 plays a supporting role.

[0062] In one embodiment, the first chuck seat 3 is a conventional chuck seat 2 , that is, the first chuck seat 3 only includes an upper cover plate 21 and a lower cover plate 22 , and the whole is a square structure, and there is no wire pressing portion 24 on the first chuck seat 3 .

[0063] In one embodiment, see the attached Figure 7 and attached Fig. 9 As shown, two cable modules 1 are arranged at intervals along the Y direction. Figure 5 As shown, the clamping cavity 23 and the wire pressing part 24 are arranged corresponding to the cable module 1. In order to limit each cable module 1, two wire pressing parts 24 are also arranged, and the wire pressing parts 24 limit the corresponding cable module 1.

[0064] In this embodiment, the limiting plate 242 can cover the first cable assembly 11 and the second cable assembly 12 in the Z direction.

[0065] Of course, in some embodiments, three, four or more cable modules 1 may be provided.

[0066] In one embodiment, see the attached Figure 8 and attached Fig. 9 As shown, the cable module 1 also includes an air pipe assembly 13, which is parallel to the second cable assembly 12 and is distributed up and down with the second cable assembly 12, and the second cable assembly 12 is located outside the air pipe assembly 13. The air pipe assembly 13 includes a plurality of air pipe bodies distributed along the Y direction, and all the air pipe bodies are fixed in the air pipe sleeve.

[0067] See attached Figure 4 As shown, at this time, the first chuck seat 3 and the second chuck seat both include a partition 25, which is fixed between the upper cover plate 21 and the lower cover plate 22, and divides the clamping cavity 23 into a first cavity 231 and a second cavity 232 that are distributed up and down and are not conductive, the first cable assembly 11 and the second cable assembly 12 are located in the second cavity 232, and the air pipe assembly 13 is located in the first cavity 231.

[0068] In this embodiment, because the cable assembly is further added with the air pipe assembly 13 , the limiting plate 242 can cover the first cable assembly 11 , the second cable assembly 12 and the air pipe assembly 13 in the Z direction.

[0069] In this embodiment, because the cable module 1 integrates the trachea assembly 13, the trachea body can be used as a support, and in addition to playing a ventilation role, it can also play a role as a keel.

[0070] In this embodiment, the thickness of each cover plate on the chuck seat 2 is related to the cable module 1. While ensuring the fixation of the cable module 1, the chuck seat 2 is as light and thin as possible to reduce the weight of the chuck seat 2 and the resistance of the flat drag chain cable module during movement.

[0071] The above implementation modes are only for illustrating the technical concept and features of the utility model, and their purpose is to allow people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
