[0030] Example 1

[0031] See also Figure 1-Figure 3 This embodiment provides a purlin connecting device to solve the problem that it is difficult to adjust the distance between two adjacent purlins after the existing connecting parts are installed.

[0032] In this embodiment, the purlin connecting device includes a transition plate 10 inserted between two adjacent purlins 40 and a connecting plate 30 hinged on the purlin 40. A rotatable screw 11 is provided on the transition plate 10, and a lifting plate 20 is screwed on the screw 11. The two ends of the lifting plate 20 are provided with a card slot 22. The end of the connecting plate 30 is provided with a pressing plate 31 that can cover the card slot 22, and the inner side of the pressing plate 31 is provided with a clamping head 32 that is rotatably plugged into the card slot 22.

[0033] In this embodiment, the connecting plate 30 can be driven to swing by rotating the screw rod 11, so that two adjacent purlins 40 can move relative to each other, thereby achieving the purpose of adjusting the distance between two adjacent purlins 40, and having the advantage of simple operation.

[0034] It should be noted that, in the present embodiment, the purlin 40 is a C-shaped purlin, and two adjacent purlins 40 are arranged along the same straight line direction. The transition plate 10 is U-shaped along the cross section. The outer shape of the transition plate 10 is adaptively inserted into the butt ends of the two adjacent purlins 40. The outer wall of the transition plate 10 fits the inner cavity defined by the purlin 40. A rotatable screw 11 is provided between the upper and lower inner walls of the transition plate 10, and the screw 11 is arranged vertically with the upper and lower inner walls of the transition plate 10. As an example, the screw 11 is arranged in the middle position of the transition plate 10 along the length direction. A sleeve 21 is integrally formed on the lifting plate 20, and the sleeve 21 is screwed onto the screw 11. The lifting plate 20 is arranged as a whole between the sleeve 21 and the transition plate 10, and the lifting plate 20 fits with the transition plate 10, so that the lifting plate 20 is only allowed to move up and down along the axial direction of the screw 11.

[0035] In addition, the card slot 22 is formed at the two ends of the lifting plate 20, and the card slot 22 is symmetrically arranged on both sides of the sleeve 21, and the axis of the card slot 22 is perpendicular to the axis of the sleeve 21. As an example, the card slot 22 is constructed as a through hole that passes through the lifting plate 20.

[0036] In addition, the connecting plate 30 is rotatably hinged to the inside of the purlin 40 by bolts, and the connecting plate 30 is symmetrically arranged on both sides of the screw rod 11, and the rotation axis of the connecting plate 30 is parallel to the axis of the slot 22. A disc-shaped pressing plate 31 is integrally formed at the movable end of the connecting plate 30, and the diameter of the pressing plate 31 is larger than the diameter of the slot 22. The pressing plate 31 and the slot 22 are coaxially arranged, and the clamping head 32 is integrally formed on the inner side wall of the pressing plate 31, and the clamping head 31 is The whole is constructed in a cylindrical shape coaxially arranged with the pressing plate 31. The outer diameter of the clamping head 32 is equal to the diameter of the clamping slot 22. The clamping head 32 is integrally inserted into the inside of the clamping slot 22 in a rotatable manner, and the pressing plate 31 is attached to the outer end surface of the clamping slot 22. By means of the rotational insertion of the clamping head 32 and the clamping slot 22, a hinged fit can be formed between the connecting plate 30 and the lifting plate 20. By means of the press fit between the pressing plate 31 and the lifting plate 20, the transition plate 10 can be integrally restricted inside the purlin 40.

[0037] When in use, the lifting plate 20 is driven to move along the axial direction of the screw rod 11 by rotating the screw rod 11, and the rotation and plug-in cooperation of the clamping head 32 and the clamping groove 22 can drive the connecting plate 30 to swing, so that the two adjacent purlins 40 move relative to each other, thereby achieving the purpose of fine-tuning the distance between the two adjacent purlins 40.

[0038] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
