[0029] like Figures 1-3 As shown, a convenient support and guide device for cable chains includes two symmetrically distributed limiting plates 11 and a support roller 12 installed between the two limiting plates 11. A vertical plate 13 is provided on the lower side of the limiting plate 11. A horizontal plate 14 is integrally formed on the inner side of the vertical plate 13 (the side of the two vertical plates 13 that are close to each other in a convenient support and guide device for cable chains). A locking component is installed on the lower side of the horizontal plate 14. The locking component is used to fix the convenient support and guide device for cable chains to the cable chain.

[0030] Specifically, the locking assembly includes a retaining plate 15, the left and right edges of which are bent upwards. The retaining plate 15 is connected to the horizontal plate 14 by fasteners. In this embodiment, the fasteners are bolts and nuts. The bolts are inverted and pass upwards through the horizontal plate 14, and are locked by the nuts. The operator can adjust the distance between the retaining plate 15 and the horizontal plate 14 by rotating the nuts. By clamping the components inside the cable chain between the horizontal plate 14 and the retaining plate 15, the installation and fixing of the convenient support and guide device for the cable chain on the cable chain is completed.

[0031] Furthermore, the locking assembly also includes a cover plate 16 fixed to the lower side of the horizontal plate 14 and penetrated by the fastener. The cover plate 16 is provided to prevent the horizontal plate 14 from contacting the cable chain and to prevent scratches on the surface of the cable chain.

[0032] To further improve the connection stability of the enclosure 15 and facilitate the installation of the bolts, an insert plate 17 penetrating the enclosure 15 is provided on the lower side of the cover plate 16, and two sets of fasteners are provided, distributed on the left and right sides of the enclosure 15.

[0033] Furthermore, a reinforcing plate 20 is connected between the horizontal plate 14 and the vertical plate 13.

[0034] In a second embodiment of the convenient support and guide device for cable chains, in order to realize the up-down adjustable design of the support roller 12, the limiting plate 11 is provided with a vertically extending adjustment groove 21, and the limiting plate 11 is provided with a screw that passes through the adjustment groove 21 and is threadedly connected to the support roller 12.

[0035] Furthermore, the screw includes a head and a screw rod. The wall of the adjusting groove 21 is provided with a plurality of arc-shaped grooves arranged at equal intervals along the length direction. The size of the arc-shaped grooves is adapted to the head. After the screw is installed, the head is inserted into one of the arc-shaped grooves. This design of the arc-shaped grooves can prevent the screw from sliding up and down in the adjusting groove 21 and prevent the support roller 12 from sinking under force.

[0036] In addition, in order to reduce the friction between the support roller 12 and the upper drag chain, the support roller 12 is rotatably connected to a sleeve 18.

[0037] To prevent the cable chain from colliding or getting stuck with the limiting plate 11 when it is attached to the support roller 12, a guide plate 19 is integrally formed on the side of the limiting plate 11, and the guide plate 19 is inclined in a direction away from the support roller 12.

[0038] Furthermore, the limiting plate 11 and the vertical plate 13 are connected by an inclined plate, and the distance between the front and rear limiting plates 11 is greater than the distance between the front and rear vertical plates 13. With this design, while the vertical plate 13 is attached to the cable chain to complete the installation and fixation, the limiting plate 11 can have a certain distance from the cable chain, reducing interference and obstruction.

[0039] In this embodiment, the horizontal plate 14 is formed by processing two grooves on the bottom of the vertical plate 13, and then bending the part of the vertical plate 13 between the grooves to form the horizontal plate 14. This is an integral molding process, which is convenient for production.

[0040] like Figure 4-5 As shown, a cable chain is provided with a plurality of convenient support and guide devices for cable chains. Specifically, the cable chain includes a plurality of chain links that are hinged to each other. Each chain link includes two side support plates and an upper cover plate and a lower cover plate connected between the support plates. Two horizontally adjacent upper cover plates are clamped between the side plate 15 and the cross plate 14 in one of the convenient support and guide devices for cable chains, or they can be regarded as being clamped between the side plate 15 and the cover plate 16.

[0041] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.

[0042] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
