[0026] Reference Figures 1 to 6 The flexible dust-free drag chain assembly according to the preferred embodiment of the present application will be described in detail below, wherein the flexible dust-free drag chain assembly comprises a housing sealing member 10, at least three connecting members 20 and at least one slide port clamp 30.

[0027] Specifically, the housing closure member 10 comprises a first closure member 11 and a second closure member 12. The first closure member 11 has two first edge portions 111 and at least one first partition portion 112, the two first edge portions 111 are formed on both sides of the first closure member 11 in the extending direction of the first closure member 11, and the first partition portion 112 is formed between the two first edge portions 111 and has the same extending direction as the first edge portions 111. The second closure member 12 has two second edge portions 121 corresponding to the two first edge portions 111 and at least one second partition portion 122 corresponding to the first partition portion 112, the two second edge portions 121 are formed on both sides of the second closure member 12 in the extending direction of the second closure member 12, and the second partition portion 122 has the same extending direction as the second edge portions 121.

[0028] The connecting member 20 comprises a clamping groove portion 21 and a clamping cap 22. The clamping groove portions 21 and the clamping caps 22 of the three connecting members 20 are arranged between the two first edge portions 111 and the two second edge portions 121 and between the first partition portion 112 and the second partition portion 122 in the extending direction of the housing closure member 10 in an opposite manner, respectively, and the clamping cap 22 of the connecting member 20 can be clamped and clamped into the clamping groove portion 21 of the connecting member 20.

[0029] The sliding port clamp 30 comprises at least one pair of first sliding clamp portions 31 and at least one support portion 32. One pair of first sliding clamp portions 31 are connected to each other through the support portion 32, and one pair of first sliding clamp portions 31 are arranged in opposite ways with a predetermined distance and form a first open port 3101 between one pair of first sliding clamp portions 31, and one pair of first sliding clamp portions 31 are used to clamp the first closure member 11 and the second closure member 12 when the first closure member 11 and the second closure member 12 partially enter the first open port 3101, so that under the clamping action of one pair of first sliding clamp portions 31, the three clamping caps 22 located between the first closure member 11 and the second closure member 12 are clamped into the corresponding clamping groove portions 21, and at least two cable passing channels 101 are formed between the first closure member 11 and the second closure member 12, and the cable passing channels 101 are used to place at least one cable 91.

[0030] Preferably, the support portion 32 is made of elastic material, so that when the opening size of the first open port 3101 between one pair of first sliding clamp portions 31 increases, one pair of first sliding clamp portions 31 always maintains the trend of relative convergence.

[0031] As an example, in order to make the first closure 11 and the second closure 12 smoothly enter the first opening 3101, a pair of the first slide clamping portions 31 need to be forced to be separated from each other before the first closure 11 and the second closure 12 enter the first opening 3101, so that the support portion 32 is elastically deformed, and the force for separating a pair of the first slide clamping portions 31 from each other is released after the first closure 11 and the second closure 12 enter the first opening 3101, so that a pair of the first slide clamping portions 31 clamp the first closure 11 and the second closure 12 under the elastic recovery force of the support portion 32.

[0032] Wherein, when the first edge portion 111 of the first closure 11 and the second edge portion 121 of the second closure 12 enter the first opening 3101, a pair of the first slide clamping portions 31 will clamp the first edge portion 111 and the second edge portion 121, so that the snap-in cap 22 located between the first edge portion 111 and the second edge portion 121 is continuously snapped into the card slot portion 21 by a pair of the first slide clamping portions 31 during the sliding process of a pair of the first slide clamping portions 31 along the extension direction of the card slot portion 21 in a manner of maintaining clamping the first edge portion 111 and the second edge portion 121, so that the first edge portion 111 is connected to the second edge portion 121 by snapping the snap-in cap 22 into the card slot portion 21. Similarly, the first separation portion 112 is connected to the second separation portion 122 by snapping the snap-in cap 22 into the card slot portion 21, and the steps are similar to the above steps, which will not be described in detail here.

[0033] As a preferred, the distance between a pair of the first slide clamping portions 31 is less than the sum of the thickness of the first closure 11 and the thickness of the second closure 12. When the first closure 11 and the second closure 12 partially enter the first opening 3101 and a pair of the first slide clamping portions 31 clamp the first closure 11 and the second closure 12, the first closure 11 and the second closure 12 are subjected to a force of relatively approaching at the clamped position by a pair of the first slide clamping portions 31, so as to snap the snap-in cap 22 into the card slot portion 21.

[0034] In the process of the snap-in cap 22 being snapped into the snap groove portion 21, the first opening 3101 gradually decreases in size, and at this time, because the distance between the pair of first slide clamping portions 31 is less than the sum of the thickness of the first closure 11 and the thickness of the second closure 12, the pair of first slide clamping portions 31 always clamp the first closure 11 and the second closure 12, thereby avoiding the pair of first slide clamping portions 31 from falling off the surfaces of the first closure 11 and the second closure 12, respectively.

[0035] It should be noted that, in order to enable the pair of first slide clamping portions 31 to clamp not only the first edge portions 111 and the second edge portions 121 opposite to the first edge portions 111, but also the first partition portions 112 between the two first edge portions 111 and the second partition portions 122 between the two second edge portions 121 and corresponding to the first partition portions 112, the length of the pair of first slide clamping portions 31 needs to be increased. According to the principle of leverage, when the length of the pair of first slide clamping portions 31 is increased, the force of the ends of the pair of first slide clamping portions 31 away from the support portion 32 to move closer to each other under the action of the resilience of the support portion 32 decreases, so that the first partition portions 112 and the second partition portions 122 cannot be clamped by the pair of first slide clamping portions 31 to snap the snap-in cap 22 into the snap groove portion 21.

[0036] Preferably, the slide opening clamp 30 further comprises at least one pair of second slide clamping portions 33 corresponding to the at least one pair of first slide clamping portions 31. The pair of second slide clamping portions 33 are oppositely arranged at a predetermined distance and are respectively connected to the pair of first slide clamping portions 31, and a second opening 3301 is formed between the pair of second slide clamping portions 33. The first closure 11 further comprises at least one pair of first bent grooves 1101 corresponding to the first partition portions 112. The pair of first bent grooves 1101 are arranged on both sides of the first partition portions 112 in the extension direction. The second closure 12 further comprises at least one pair of second bent grooves 1201 corresponding to the second partition portions 122, and the pair of second bent grooves 1201 are arranged on both sides of the second partition portions 122 in the extension direction.

[0037] As Figure 3 and Figure 4As shown, as an example, since a pair of the first bending grooves 1101 are arranged on both sides of the first partition portion 112 in the extending direction, and a pair of the second bending grooves 1201 are arranged on both sides of the second partition portion 122 in the extending direction, after the first closure member 11 and the second closure member 12 are respectively folded about the first bending groove 1101 and the second bending groove 1201, the folded first closure member 11 and the folded second closure member 12 can be placed in the second open port 3301 between a pair of the second sliding clamping portions 33, and then the folded first closure member 11 and the folded second closure member 12 clamp the first partition portion 112 of the first closure member 11 and the second partition portion 122 of the second closure member 12, so that the cap-in cap 22 between the first partition portion 112 and the second partition portion 122 is clamped into the clamping groove portion 21 by a pair of the supporting portions 32.

[0038] In order to smoothly enter the second open port 3301, a pair of the second sliding clamping portions 33 are forced to be separated away from each other before the folded first closure member 11 and the folded second closure member 12 enter the second open port 3301, so that the supporting portions 32 are elastically deformed, and then the force for separating a pair of the second sliding clamping portions 33 is removed after the folded first closure member 11 and the folded second closure member 12 enter the second open port 3301, so that a pair of the second sliding clamping portions 33 clamp the folded first closure member 11 and the folded second closure member 12 under the elastic restoring force of the supporting portions 32, and then a pair of the second sliding clamping portions 33 clamp the first partition portion 112 of the first closure member 11 and the second partition portion 122 of the second closure member 12 under the elastic restoring force of the supporting portions 32.

[0039] Secondly, a pair of the second slide clamping portions 33 clamp the first partition portion 112 of the first closure piece 11 and the second partition portion 122 of the second closure piece 12 through the first closure piece 11 after being folded and the second closure piece 12 after being folded, so that the cap-in hat 22 between the first partition portion 112 and the second partition portion 122 is clamped into the card slot portion 21 by the pair of the second slide clamping portions 33, and then the cap-in hat 22 between the first partition portion 112 and the second partition portion 122 is clamped into the card slot portion 21 during the sliding of the pair of the second slide clamping portions 33 along the extension direction of the card slot portion 21, so that the first partition portion 112 is connected to the second partition portion 122 by clamping the cap-in hat 22 into the card slot portion 21. At the same time, the first edge portion 111 is connected to the first partition portion 112 by clamping the cap-in hat 22 into the card slot portion 21, and the material passing channel 101 is formed.

[0040] It can be understood that, compared with the way of increasing the length of the first slide clamping portion 31 to clamp the first partition portion 112 and the second partition portion 122 by a pair of the first slide clamping portions 31, the length of the second slide clamping portion 33 required in the way of placing the first closure piece 11 after being folded along the first bending groove 1101 and the second closure piece 12 after being folded along the second bending groove 1201 into the second open mouth 3301 and indirectly clamping the first partition portion 112 and the second partition portion 122 by a pair of the second slide clamping portions 33 is smaller, so that the first partition portion 112 and the second partition portion 122 are easily clamped by a pair of the second slide clamping portions 33 to clamp the cap-in hat 22 between the first partition portion 112 and the second partition portion 122 into the card slot portion 21.

[0041] It is worth mentioning that the cable 91 can be placed between the first closure piece 11 and the second closure piece 12, so that the cable 91 is placed in the material passing channel 101 when the first edge portion 111 is connected to the first partition portion 112 by clamping the cap-in hat 22 into the card slot portion 21, and the first partition portion 112 is connected to the second partition portion 122 by clamping the cap-in hat 22 into the card slot portion 21.

[0042] Meanwhile, when the cable 91 is brittle and needs to be replaced, the first and second edge portions 111 and 121 can be separated from the first and second partition portions 112 and 122 by separating the card slot portion 21 and the card-in cap 22, so that the cable 91 in the cable passage 101 can be replaced, and the brittle cable 91 can be taken out completely without being broken.

[0043] Therefore, the first edge portion 111 is connected to the first partition portion 112 by the card-in cap 22 and the card slot portion 21, and the first partition portion 112 is connected to the second partition portion 122 by the card-in cap 22 and the card slot portion 21, so that the cable 91 can be placed in the cable passage 101 and the cable 91 that needs to be replaced can be taken out of the cable passage 101 by separating the card slot portion 21 and the card-in cap 22.

[0044] Preferably, the opening size of the second opening 3301 is larger than that of the first opening 3101.

[0045] Preferably, the first and second slide clamping portions 31 and 33 are integrally formed.

[0046] It can be understood that during the process of pinching a pair of the second slide clamping portions 33 and reducing the opening size of the second opening 3301, since each of the second slide clamping portions 33 is connected to the corresponding first slide clamping portion 31, according to the principle of leverage, the first and second slide clamping portions 31 and 33 will rotate as a whole around the support portion 32 as the fulcrum, thereby increasing the opening size of the first opening 3101, so that the first and second edge portions 111 and 121 can enter the first opening 3101, and when the pinching of the pair of the second slide clamping portions 33 is stopped, the pair of the first slide clamping portions 31 can clamp the first and second edge portions 111 and 121. Similarly, by pinching a pair of the first slide clamping portions 31, the opening size of the second opening 3301 between the pair of the second slide clamping portions 33 can be increased.

[0047] That is, a pair of the first slide clamping portions 31 can not only clamp the first edge portion 111 and the second edge portion 121, but also serve as a power arm to increase the opening size of the second opening 3301 between a pair of the second slide clamping portions 33; a pair of the second slide clamping portions 33 can not only clamp the first partition portion 112 of the first closure member 11 and the second partition portion 122 of the second closure member 12 through the folded first closure member 11 and the folded second closure member 12, but also serve as a power arm to increase the opening size of the first opening 3101 between a pair of the first slide clamping portions 31.

[0048] Preferably, the first closure member 11 further has at least one pair of first receiving spaces 1102 corresponding to the first partition portion 112, a pair of the first receiving spaces 1102 are arranged on both sides of the first partition portion 112 along the extension direction of the first partition portion 112, and the first partition portion 112 has the first bending groove 1101 and the first receiving space 1102 arranged on both sides along the extension direction of the first partition portion 112 in sequence, and the first closure member 11 has a first thin wall portion 113 at the first receiving space 1102. The second closure member 12 further has at least one pair of second receiving spaces 1202 corresponding to the second partition portion 122, a pair of the second receiving spaces 1202 are arranged on both sides of the second partition portion 122 along the extension direction of the second partition portion 122, and the second partition portion 122 has the second bending groove 1201 and the second receiving space 1202 arranged on both sides along the extension direction of the second partition portion 122 in sequence, and the second closure member 12 has a second thin wall portion 123 at the second receiving space 1202. The first receiving space 1102 and the second receiving space 1202 are respectively matched with the first partition portion 112 and the second partition portion 122.

[0049] For example, when the first closure member 11 and the second closure member 12 are folded about the first bending groove 1101 and the second bending groove 1201 respectively, the first partition portion 112 and the second partition portion 122 are respectively received in the first receiving space 1102 and the second receiving space 1202, and the first partition portion 112 and the second partition portion 122 are respectively attached to the first thin wall portion 113 and the second thin wall portion 123, so that a pair of the second slide clamping portions 33 clamp the first partition portion 112 and the second partition portion 122 through the first thin wall portion 113 and the second thin wall portion 123, and the clamping-in cap 22 between the first partition portion 112 and the second partition portion 122 is clamped into the clamping groove portion 21.

[0050] It is worth mentioning that, due to the thin wall thickness of the first thin wall part 113 and the second thin wall part 123 formed at the first accommodating space 1102 and the second accommodating space 1202, the opening size of the second open port 3301 of the pair of second slide clamping parts 33 for clamping and pressing the first thin wall part 113 and the second thin wall part 123 to open the second open port 3301 can be reduced, thereby reducing the force required for pinching the pair of first slide clamping parts 31.

[0051] Preferably, the first edge sealing part 111 has at least one first protrusion 1111. The first edge sealing part 111 protrudes in the thickness direction of the first edge sealing part 111 in the extension direction to form the first protrusion 1111, so that when the pair of first slide clamping parts 31 slides along the extension direction of the card slot part 21 in a manner of maintaining clamping and pressing the first edge sealing part 111 and the second edge sealing part 121, the contact area between the first slide clamping part 31 and the first edge sealing part 111 is reduced to increase the friction between the first slide clamping part 31 and the first edge sealing part 111, thereby reducing the probability of the first slide clamping part 31 slipping off the surface of the first edge sealing part 111.

[0052] Preferably, the first slide clamping part 31 has at least one first fitting groove 3102 matched with the first protrusion 1111, so that when the pair of first slide clamping parts 31 slides along the extension direction of the card slot part 21 in a manner of maintaining clamping and pressing the first edge sealing part 111 and the second edge sealing part 121, the first protrusion 1111 is fitted into the first fitting groove 3102 to stabilize the direction of the first slide clamping part 31 when sliding along the surface of the first edge sealing part 111, thereby avoiding the first slide clamping part 31 from being unable to fit the card-in cap 22 between the first edge sealing part 111 and the second edge sealing part 121 into the card slot part 21 when clamping and pressing the first edge sealing part 111 and the second edge sealing part 121 due to the deviation of the sliding direction of the first slide clamping part 31.

[0053] Similarly, the second edge sealing part 121 has at least one second protrusion 1211. The second edge sealing part 121 protrudes in the thickness direction of the second edge sealing part 121 in the extension direction to form the second protrusion 1211, so that when the pair of first slide clamping parts 31 slides along the extension direction of the card slot part 21 in a manner of maintaining clamping and pressing the first edge sealing part 111 and the second edge sealing part 121, the contact area between the first slide clamping part 31 and the second edge sealing part 121 is reduced to increase the friction between the first slide clamping part 31 and the second edge sealing part 121, thereby reducing the probability of the first slide clamping part 31 slipping off the surface of the second edge sealing part 121.

[0054] Preferably, the first slide clamp portion 31 further has at least one second matching groove 3103 matched with the second protrusion 1211, so that when a pair of the first slide clamp portions 31 slide along the extending direction of the card slot portion 21 in a manner of holding and clamping the first sealing edge portion 111 and the second sealing edge portion 121, the second protrusion 1211 is clamped into the second matching groove 3103 to stabilize the direction of the first slide clamp portion 31 when sliding along the surface of the second sealing edge portion 121, so as to avoid the first slide clamp portion 31 from deviating from the sliding direction and failing to clamp the clamping cap 22 between the first sealing edge portion 111 and the second sealing edge portion 121 into the card slot portion 21 when clamping the first sealing edge portion 111 and the second sealing edge portion 121.

[0055] Preferably, the shell closing member 10 is made of expanded polytetrafluoroethylene.

[0056] Preferably, the second slide clamp portion 33 has a plurality of second anti-skid strips 331. A pair of the second slide clamp portions 33 extend partially into the second open mouth 3301 to form a plurality of the second anti-skid strips 331, so that when a pair of the second slide clamp portions 33 slide along the extending direction of the card slot portion 21 in a manner of holding and clamping the folded first closing member 11 and the folded second closing member 12, the contact area of a pair of the second slide clamp portions 33 with the first closing member 11 and the second closing member 12 is reduced respectively to increase the friction between a pair of the second slide clamp portions 33 and the first closing member 11 and the second closing member 12 respectively, thereby reducing the probability of a pair of the second slide clamp portions 33 slipping off the surface of the first closing member 11 and the second closing member 12 respectively.

[0057] In the embodiment, the card slot portion 21 is implemented as a groove opened along the extending direction of the shell closing member 10. The clamping cap 22 is implemented as a convex cap protruding towards the card slot portion 21 along the extending direction of the shell closing member 10 and matched with the card slot portion 21. In the direction perpendicular to the extending direction of the first closing member 11, the card slot portion 21 and the clamping cap 22 of the adjacent connecting member 20 are arranged alternately on the first closing member 11. In the direction perpendicular to the extending direction of the second closing member 12, the card slot portion 21 and the clamping cap 22 of the adjacent connecting member 20 are arranged alternately on the second closing member 12 in a manner corresponding to the clamping cap 22 and the card slot portion 21 arranged on the first closing member 11 respectively.

[0058] That is, the card slot part 21 of one of the connecting members 20 is provided in the extension direction of one of the first edge parts 111, the card-in cap 22 of one of the connecting members 20 is provided in the extension direction of one of the second edge parts 121, the card-in cap 22 of the other connecting member 20 is provided in the first division part 112 adjacent to one of the first edge parts 111, and the card slot part 21 of the other connecting member 20 is provided in the second division part 122 adjacent to one of the second edge parts 121.

[0059] In a variant, the card slot part 21 of three of the connecting members 20 is provided in the extension direction of the first closure 11 in two of the first edge parts 111 and the first division part 112, and the card-in cap 22 of three of the connecting members 20 is provided in the extension direction of the second closure 12 in two of the second edge parts 121 and the second division part 122.

[0060] In another variant, the card slot part 21 of three of the connecting members 20 is provided in the extension direction of the second closure 12 in two of the second edge parts 121 and the second division part 122, and the card-in cap 22 of three of the connecting members 20 is provided in the extension direction of the first closure 11 in two of the first edge parts 111 and the first division part 112.

[0061] To take out the snap-in cap 22 from the card slot 21, the snap-in cap 22 needs to be tilted towards one side of the card slot 21, so that one side of the card slot 21 is deformed to increase the cross-sectional size of the deformed card slot 21, and then the snap-in cap 22 is taken out from the card slot 21. One of the first closures 11 is tilted relative to the second closure 12, and the first edge portion 111 of one of the first closures 11 drives the card slot 21 or the snap-in cap 22 to tilt the card slot 21 or the snap-in cap 22 at the second edge portion 121 of one of the second closures 12, and causes the snap-in cap 22 to be separated from the card slot 21. Because in the direction perpendicular to the extension direction of the first closure 11, the card slot 21 and the snap-in cap 22 of the adjacent connecting member 20 are arranged in the first closure 11 in an alternating manner, and in the direction perpendicular to the extension direction of the second closure 12, the card slot 21 and the snap-in cap 22 of the adjacent connecting member 20 are arranged in the second closure 12 in a corresponding manner to the card slot 21 and the snap-in cap 22 arranged in the first closure 11, respectively, the first partition portion 112 of the tilted first closure 11 cannot further separate the snap-in cap 22 between the first partition portion 112 and the second partition portion 122 from the card slot 21. Therefore, the snap-in cap 22 between the two first edge portions 111 and the two second edge portions 121 and between the first partition portion 112 and the second partition portion 122 is buckled into the card slot 21, and forms at least two material passing channels 101, which can improve the stability of the two first closures 11 as a whole connected to the second closure 12 through the connecting member 20.

[0062] Preferably, the connecting member 20 is implemented to include a buckle.

[0063] As shown in Figures 5 to 6 It can be understood that at least one keel 92 can also be placed in the material passing channel 101 to improve the toughness of the flexible dust-free drag chain assembly for use in different scenarios.
