Description

Technical Field

[0001] The utility model belongs to the technical field of exhibition hall construction, and particularly relates to a truss support structure for an exhibition hall. Background Technique

[0002] At present, most exhibition halls, exhibition stands or temporary stages are built using truss structures. A truss is a beam-like structure formed by connecting rods through welding, riveting or bolting. When building a truss-type exhibition hall, exhibition stand or temporary stage, several trusses need to be erected first as support feet, and then the top is hoisted through the erected support feet. Since the erected support feet are mostly single trusses and are extremely prone to tipping over, a support structure is required to keep them upright after this part is erected.

[0003] In the Chinese patent with the publication number CN215166520U, an exhibition hall truss support structure is disclosed, which includes a support plate. The support plate is provided with at least two connecting bolts for connecting the support plate to the truss to be supported. The thickness of the support plate is not greater than the maximum diameter of the component rods of the connected truss, and the length of the support plate is not less than three times the width of the bottom end of the connected truss. A chute is opened on the upper end surface of the support plate, and the connecting bolts are slidably installed in the chute. When building the truss of an exhibition hall or exhibition stand, the truss on the ground supporting the top has a small contact area with the ground and needs a support member. The connecting bolts are adjusted through the chute to fit the connecting holes at the bottom end of the truss, and then the support plate and the truss are fixed through the connecting bolts. When the truss is erected, the support plate provides a support in the length direction of the support plate for the truss.

[0004] In addition, when this exhibition hall truss support structure is in use, although it can be used well for the exhibition hall truss, when connecting the exhibition hall truss to the base, the support effect on both sides of the exhibition hall truss is not high, reducing the support area of the exhibition hall truss, and the storage effect of the exhibition hall truss support rods is not high, reducing the convenience of storing the exhibition hall truss support.

One end of the worm 8 is fixedly connected to a knob 9. The outer wall of the worm 8 meshes with a worm gear 10 that is rotatably connected to the inner wall of the storage plate 4. The rotation center of the worm gear 10 is fixedly connected to a rotating rod 11 that is rotatably connected to the outer wall of the storage plate 4. When using the exhibition hall truss for support, in order to improve the stability of the exhibition hall truss during placement, the first bolt 6 can be rotated first, so that the first bolt 6 slides out from the outer wall of the storage plate 4, and the storage plate 4 is pulled, so that the storage plate 4 slides out from the inner wall of the placement plate 1. At the same time, the bolt is slid into the inner wall of the card slot 7 to play a role in clamping and fixing the storage plate 4. The knob 9 is rotated, and through the rotation of the worm 8, the worm gear 10 is driven to rotate. The rotation of the worm gear 10 drives the rotating rod 11 to rotate, playing a role in pre-positioning and supporting the exhibition hall truss.

[0028] Specifically, an adjustment groove is provided on the outer wall of the storage plate 4 on one side of the card slot 7, and the adjustment groove is on the same horizontal plane as the card slot 7. A connection groove is provided at the connection part between the inner wall of the placement plate 1 and the storage plate 4, which is beneficial to the stability of the storage of the storage plate 4 by providing an adjustment groove on the outer wall of the storage plate 4 on one side of the card slot 7.

[0029] Specifically, a storage groove is provided at the connection part between the outer wall of the storage plate 4 and the rotating rod 11, and both the storage plate 4 and the rotating rod 11 are symmetrically arranged on both sides of the connection bracket 2, which is beneficial to the effective folding and storage of the rotating rod 11 by providing a storage groove at the connection part between the outer wall of the storage plate 4 and the rotating rod 11.

[0030] Specifically, the rotation centers of the worm gear 10 and the rotating rod 11 coincide with each other. The rotating rod 11 and the receiving plate 4 form a flipping structure through the worm 8 and the worm gear 10, which plays a role in pre-positioning and supporting the exhibition hall truss.

[0031] Embodiment 2:

[0032] Reference Figure 1 、 Figure 2 、 Figure 5 and Figure 6 As shown in FIGS. , a threaded rod 12 is rotatably connected to the outer wall of the rotating rod 11. One end of the threaded rod 12 is fixedly connected to a servo motor 13. An expansion rod 14 that is threadedly connected to the outer wall of the threaded rod 12 and slidably connected to the outer wall of the rotating rod 11. A positioning block 15 that fits against the outer wall of the expansion rod 14 is fixedly connected to the outer wall of the connecting bracket 2. A second nut 16 is provided on the outer wall of the positioning block 15. A second bolt 17 that is threadedly connected to the inner wall of the second nut 16 and slidably connected to the outer wall of the expansion rod 14. A positioning groove 18 is formed at the connection portion between the outer wall of the expansion rod 14 and the second bolt 17. When the exhibition hall truss is in daily use, in order to improve the stability of the exhibition hall truss placed on the placing plate 1, when the rotating rod 11 is rotated to the required angle, the servo motor 13 can be turned on to drive the expansion rod 14 to slide along the outer wall of the rotating rod 11 through the rotation of the threaded rod 12, so that the expansion rod 14 moves to the inner side wall of the positioning block 15, and the second bolt 17 is rotated. Through the limiting action of the second nut 16, the second bolt 17 slides into the inner wall of the positioning groove 18, achieving the effect of effectively supporting and fixing both sides of the exhibition hall truss by the expansion rod 14.

[0033] Specifically, a limiting groove is formed at the connection portion between the outer wall of the rotating rod 11 and the expansion rod 14. The expansion rod 14 and the rotating rod 11 form a telescopic structure through the threaded rod 12, which is beneficial to the rotation of the threaded rod 12, driving the expansion rod 14 to perform telescopic movement along the outer wall of the rotating rod 11, playing a role in driving the effective connection between the expansion rod 14 and the positioning block 15.

[0034] Specifically, the outer wall contour of the positioning block 15 is in a "U" shape, and the positioning block 15 is arranged on the movement track of the rotating rod 11, which is beneficial to the pre-positioning and clamping of the expansion rod 14 through the "U" shape of the outer wall contour of the positioning block 15.

[0035] Specifically, the inner wall contour of the positioning groove 18 is larger than the outer wall contour of the second bolt 17. The expansion rod 14 and the positioning block 15 through the second bolt 17 and the positioning groove 18 are beneficial to the sliding of the second bolt 17 along the inner wall of the positioning groove 18, driving the clamping and fixing between the expansion rod 14 and the positioning block 15, achieving the effect of effectively supporting and fixing both sides of the exhibition hall truss by the expansion rod 14.

[0036] Working principle: First, when it is used for support through the exhibition hall truss, in order to improve the stability of the exhibition hall truss during placement, the first bolt 6 can be rotated first, so that the first bolt 6 slides out from the outer wall of the storage plate 4, and the storage plate 4 is pulled to make the storage plate 4 slide out from the inner wall of the placement plate 1. At the same time, the bolt slides into the inner wall of the card slot 7 to play a role in clamping and fixing the storage plate 4, and the knob 9 is rotated. Through the rotation of the worm 8, the worm gear 10 is driven to rotate. The rotation of the worm gear 10 drives the rotating rod 11 to rotate, playing a role in pre-positioning and supporting the exhibition hall truss.

[0037] Finally, when the exhibition hall truss is used daily, in order to improve the stability of the exhibition hall truss placed on the placement plate 1, when the rotating rod 11 is rotated to the required angle, the servo motor 13 can be turned on. Through the rotation of the threaded rod 12, the telescopic rod 14 is driven to slide along the outer wall of the rotating rod 11, so that the telescopic rod 14 moves to the inner side wall of the positioning block 15, and the second bolt 17 is rotated. Through the limiting action of the second nut 16, the second bolt 17 slides into the inner wall of the positioning groove 18, achieving the effect of effectively supporting and fixing both sides of the exhibition hall truss by the telescopic rod 14.

[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
