以下通过实施例来说明通道主体1的拼接结构。此外，在不同的实施例中，同样的技术特征，可能会赋予不同的附图标记。The following is an example to illustrate the splicing structure of the channel body 1. In addition, in different embodiments, the same technical features may be given different reference numerals.
【实施例1】[Example 1]
参照图9，在实施例1中，通道主体1a包括相互组装的一个第一通道组件101以及一个第二通道主体102。9 , in Embodiment 1, the channel body 1 a includes a first channel assembly 101 and a second channel body 102 that are assembled with each other.
第一通道组件101一侧外侧固定连接有单卡槽103(为了便于区分，也将第一通道组件101的一侧的单卡槽称为“第一单卡槽103a”)，第一通道组件101的与单卡槽103相对一边固定连接有混合卡座105，此外，在第一通道组件101的混合卡座105中，卡条位于第一通道组件101的内侧，卡槽位于第一通道组件101的外侧(为便于区分，也将卡条位于内侧、卡槽位于外侧的混合卡座称为“第一混合卡座105a”)。A single card slot 103 is fixedly connected to the outer side of one side of the first channel component 101 (for the sake of distinction, the single card slot on one side of the first channel component 101 is also referred to as the "first single card slot 103a"). A hybrid card socket 105 is fixedly connected to the side of the first channel component 101 opposite to the single card slot 103. In addition, in the hybrid card socket 105 of the first channel component 101, the card strip is located on the inner side of the first channel component 101, and the card slot is located on the outer side of the first channel component 101 (for the sake of distinction, the hybrid card socket with the card strip located on the inner side and the card slot located on the outer side is also referred to as the "first hybrid card socket 105a").
第二通道组件102的与第一单卡槽103a对应的一侧固定连接有单卡条104(为便于区分，也将第二通道组件102的一侧的单卡条称为“第一单卡条104a”)，第二通道组件102的另一侧、即与第一混合卡座105a相对的一侧固定连接有单卡槽103(为便于区分，也将第二通道组件102的另一侧的单卡槽称为“第二单卡槽103b”)。A single card strip 104 is fixedly connected to one side of the second channel component 102 corresponding to the first single card slot 103a (for the sake of distinction, the single card strip on one side of the second channel component 102 is also referred to as the "first single card strip 104a"). A single card slot 103 is fixedly connected to the other side of the second channel component 102, i.e., the side opposite to the first hybrid card holder 105a (for the sake of distinction, the single card slot on the other side of the second channel component 102 is also referred to as the "second single card slot 103b").
在将第一通道组件101和第二通道组件102相互组装时，第二通道组件102的第一单卡条104a卡到第一通道组件101的第一单卡槽103a中，第一通道组件101的第一混合卡座105a中的卡条则卡到第二通道组件102的第二单卡槽103b中。When the first channel assembly 101 and the second channel assembly 102 are assembled together, the first single card strip 104a of the second channel assembly 102 is inserted into the first single card slot 103a of the first channel assembly 101, and the card strip in the first mixed card holder 105a of the first channel assembly 101 is inserted into the second single card slot 103b of the second channel assembly 102.
由此，完成第一通道组件101和第二通道组件102的相互组装，并且，由于第一通道组件101的第一混合卡座105a中，还具有位于外侧的卡槽，因此，可以通过该卡槽和其他的通道主体1的混合卡座105进行拼接。从而能够增加拖链的通道数量。Thus, the mutual assembly of the first channel assembly 101 and the second channel assembly 102 is completed, and since the first mixed card holder 105a of the first channel assembly 101 also has a card slot located on the outside, the mixed card holder 105 of other channel bodies 1 can be spliced through the card slot, thereby increasing the number of channels of the drag chain.
【实施例2】[Example 2]
继续参照图9，在实施例2中，通道主体1b包括相互组装的一个第一通道组件101a以及一个第二通道主体102a。 9 , in Embodiment 2, the channel body 1 b includes a first channel assembly 101 a and a second channel body 102 a that are assembled with each other.
如上所述，混合卡座105为卡槽与卡条结构共同组成，且混合卡座105中的卡槽与卡条位置为一种如附图8所示(即第一混合卡座105a)。另一种则为卡槽与卡条位置对调结构(在此，为便于区分，将卡槽与卡条位置对调的混合卡座也称为“第二混合卡座105b”)，以此便于通过不同的两个混合卡座105进行咬合连接。As described above, the hybrid card holder 105 is composed of a card slot and a card strip structure, and the positions of the card slot and the card strip in the hybrid card holder 105 are as shown in FIG8 (i.e., the first hybrid card holder 105a). The other is a structure in which the positions of the card slot and the card strip are swapped (herein, for the sake of distinction, the hybrid card holder in which the positions of the card slot and the card strip are swapped is also referred to as the "second hybrid card holder 105b"), so as to facilitate the engagement connection through two different hybrid card holders 105.
具体地，在实施例2中，第一通道组件101a一侧外侧固定连接有单卡条104(为了便于区分，也将第一通道组件101a的一侧的单卡条称为“第二单卡条104b”)，第一通道组件101a的与第二单卡条104b相对一边固定连接有第二混合卡座105b，并且，在第二混合卡座105b的卡槽与卡条的位置相对于第一混合卡座105a对调，即，在第二混合卡座105b中，卡槽位于内侧，卡条位于外侧。Specifically, in Example 2, a single card strip 104 is fixedly connected to the outer side of one side of the first channel component 101a (for the sake of distinction, the single card strip on one side of the first channel component 101a is also referred to as the "second single card strip 104b"), and a second hybrid card holder 105b is fixedly connected to the side of the first channel component 101a opposite to the second single card strip 104b, and the positions of the card slot and the card strip of the second hybrid card holder 105b are swapped relative to the first hybrid card holder 105a, that is, in the second hybrid card holder 105b, the card slot is located on the inside and the card strip is located on the outside.
第二通道组件102a的一侧同样固定连接有第二单卡槽103b，另一侧同样固定有第一单卡条104a。但是，与实施例1的不同之处在于，在与第一通道组件101a进行组装时，第二通道组件102a的第二单卡槽103b与第一通道组件101a的第二单卡条104b卡接，而第二通道组件102a的第一单卡条104a则与第一通道组件101a的第二混合卡座105b中的卡槽连接。The second channel component 102a is also fixedly connected to one side with a second single card slot 103b, and is also fixedly connected to the other side with a first single card strip 104a. However, the difference from the first embodiment is that, when assembled with the first channel component 101a, the second single card slot 103b of the second channel component 102a is connected to the second single card strip 104b of the first channel component 101a, and the first single card strip 104a of the second channel component 102a is connected to the card slot in the second hybrid card holder 105b of the first channel component 101a.
如此地，能够完成第一通道组件101a和第二通道组件102a的相互组装，并且，由于第一通道组件101a的第二混合卡座105b中，还具有位于外侧的卡条，因此，可以通过该卡槽和其他的通道主体1(例如通道主体1a)的混合卡座105(例如第一混合卡座105a)进行拼接。从而能够增加拖链的通道数量。In this way, the first channel assembly 101a and the second channel assembly 102a can be assembled with each other, and because the second mixed card holder 105b of the first channel assembly 101a also has a card strip located on the outside, the mixed card holder 105 (such as the first mixed card holder 105a) of other channel bodies 1 (such as the channel body 1a) can be spliced through the card slot, thereby increasing the number of channels of the drag chain.
【实施例3】[Example 3]
继续参照图9，在实施例3中，将多个通道主体1进行拼接，从而形成具有多通道的通道主体1。例如，可以至少将通道主体1a和通道主体1b进行拼接，从而形成具有双通道的通道主体1c。9 , in Example 3, a plurality of channel bodies 1 are spliced together to form a channel body 1 having multiple channels. For example, at least a channel body 1a and a channel body 1b may be spliced together to form a channel body 1c having two channels.
具体地，如实施例1所述，通道主体1a的组装中，在第一通道组件101和第二通道组件102相互组装之后，第一通道组件101的第一混合卡座105a中，还具有位于外侧的卡槽。此外，在通道主体1b的组装中，在第一通道组件101a和第二通道组件102a的相互组装之后，第一通道组件101a的第二混合卡座105b中，还具有位于外侧的卡条。在实施例3中，将通道主体1a中位于外侧的卡槽，和通道主体1b中位于外侧的卡条进行卡接，能够得到具有双通道的通道主体1c。Specifically, as described in Example 1, in the assembly of the channel body 1a, after the first channel component 101 and the second channel component 102 are assembled with each other, the first hybrid card holder 105a of the first channel component 101 also has a card slot located on the outside. In addition, in the assembly of the channel body 1b, after the first channel component 101a and the second channel component 102a are assembled with each other, the second hybrid card holder 105b of the first channel component 101a also has a card strip located on the outside. In Example 3, the card slot located on the outside of the channel body 1a and the card strip located on the outside of the channel body 1b are connected to each other, so that the channel body 1c with dual channels can be obtained.
以上仅是本申请的优选实施方式，应当指出，对本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本申请的保护范围。 The above are only preferred implementations of the present application.

These improvements and modifications should also be regarded as the scope of protection of the present application.
本申请中其他未详述部分均属于现有技术，故在此不再赘述。Other parts not described in detail in this application belong to the prior art and will not be described here.
