[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0021] It should be noted that all the directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative positional relationship, movement conditions, etc. between components in a specific posture (as shown in the attached drawings). If the specific posture changes, the directional indications will change accordingly. In the present utility model, unless otherwise clearly defined and limited, terms such as "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0022] In a first aspect, the drag chain link structure provided by the embodiments of the present utility model is as Figures 1 to 3 shown, which includes two oppositely arranged side plates 1 and a cross plate 2 connecting the two side plates 1. The cross plate 2 can be fixedly connected to the side plates 1 by an assembly method, or the cross plate 2 and the side plates 1 can be injection-molded into one body; a positioning member 3 is detachably installed on the cross plate 2. The positioning member 3 includes a bayonet portion 31 that is snap-fitted with the cross plate 2 and a positioning rod portion 32 connected to the outside of one end of the bayonet portion 31. The bayonet portion 31 has a clamping plate 33 that forms a snap connection with the two side edges in the width direction of the cross plate 2 (i.e., the direction indicated by arrow A in the figure); in the solution of this embodiment, the positioning member 3 is detachable, so that it can be replaced when the positioning member 3 is damaged, and the number of positioning members 3 can be flexibly set according to needs, with flexible use; moreover, when the positioning member 3 is installed, the oppositely arranged clamping plates 33 on the positioning member 3 are respectively snap-connected to the side edges in the width direction of the cross plate 2, so as to form a stable support for the positioning member 3, and further strengthen the stability of pipeline fixation.

[0023] Furthermore, as Figure 2 shown, in order to strengthen the connection between the positioning member 3 and the cross plate 2, a notch 34 is provided between the two opposite clamping plates 33 on the bayonet portion 31. The notch 34 is adapted to form a nested fit with the inner side of the cross plate 2. The clamping plate 33 has a clamping protrusion 35 protruding towards the notch 34. The clamping protrusion 35 is adapted to form a snap connection with the side edge of the cross plate 2. The positioning rod portion 32 is arranged on the side of the clamping plate 33 facing away from the notch 34; when the positioning member 3 is installed, a nested fit is formed between the notch 34 and the inner side of the cross plate 2, that is, the bayonet portion 3 is inserted into the drag chain link so that the notch 34 is matched with the inner side of the cross plate 2 from the inside of the drag chain link. In this way, in actual application, the pipelines arranged in the drag chain can play a role in blocking and limiting the positioning member 3, thereby strengthening the stability of the installation of the positioning member 3, and in combination with the way that the clamping protrusions 35 on the clamping plates 33 respectively form snap connections with the two side edges of the cross plate 2, the stability of the installation of the positioning member 3 on the cross plate 2 can be further strengthened.

[0024] Further referring to Figure 2 as shown, a clamping edge 21 extending along the length direction of the transverse plate 2 (i.e., Figure 1 the direction indicated by arrow B in the figure) is provided at the edge of the transverse plate 2. When the positioning member 3 is installed on the transverse plate 2, the clamping edge 21 is adapted to form a clamping connection with the clamping projection 35.

[0025] As Figure 1 shown, in order to effectively bind the pipeline to the positioning rod portion 32 using a cable tie and prevent the cable tie from slipping off the positioning rod portion 32, a notch 321 is formed on the positioning rod portion 32. When binding the pipeline, the notch 321 can position the cable tie.

[0026] Furthermore, at least two positioning rod portions 32 are provided, and at least two positioning rod portions 32 are arranged at intervals along the length direction of the transverse plate 2. By setting the number of the positioning rod portions 32 to at least two, the specific number of the positioning rod portions 32 is set according to actual needs. In actual use, more pipelines can be bound on the positioning member 3, improving the applicability.

[0027] Preferably, the positioning member 3 can slide along the length direction of the transverse plate 2. Such a setting can flexibly adjust the position of the positioning member 3 in actual use to meet the usage requirements.

[0028] In order to facilitate the positioning of multiple pipelines, in this embodiment, two transverse plates 2 are provided on the drag chain link, and the positioning member 3 is installed on both the upper and lower transverse plates 2. In this way, the number of the positioning members 3 can be increased, and thus it can adapt to the fixation of multiple pipelines.

[0029] In the second aspect, the drag chain structure provided by the embodiment of the present invention is as Figure 4 shown, and the drag chain link described in any one of the above embodiments is adopted; this drag chain has all the advantages of the drag chain link in the above embodiments, which will not be elaborated in this embodiment.

[0030] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
