[0002] A truss is a supporting beam structure made of straight rods connected by welding, riveting, or bolting. Truss members primarily bear axial tension or compression, fully utilizing the material's strength. Its structural forms vary, including triangular trusses, trapezoidal trusses, polygonal trusses (also known as broken-line trusses), and vierendeel trusses.

[0003] An exhibition hall truss disclosed in publication number CN215166565U specifically relates to the field of building supplies and includes a base plate, a support spring provided on the top of the base plate, a movable plate fixedly mounted on the top of the support spring, a sleeve fixedly mounted on the top of the movable plate, a support column fixedly mounted on the bottom of the movable plate, a connecting plate provided at the bottom of the support column, a support block provided on the top of the connecting plate, a connecting block fixedly mounted on the bottom of the connecting plate, a rotating wheel provided on one side of the connecting block, a connecting column provided on the top of the rotating wheel, an elastic connecting column provided between the base plate and the movable plate, a limit bar fixedly mounted on one side of the base plate, a fixed plate fixedly mounted on one side of the limit bar, two limit bars provided, and limit grooves provided inside the two limit bars. The utility model adjusts the angle of the movable plate by providing a rotating wheel, and fixes the movable plate by using a limit block and a limit groove, so that the truss can be installed at multiple angles, thereby improving the flexibility of truss installation and the overall practicality.

[0004] In the above structure, the angle of the movable plate is adjusted by the rotating wheel to achieve multi-angle installation of the truss. However, when the installation height of the truss needs to be adjusted, the corresponding adjustment cannot be made. Utility Model Content

[0005] The purpose of this utility model is to provide a height-adjustable exhibition hall truss. The utility model can tighten or loosen the tightening group to drive the clamping block into or out of the clamping slot, restricting or opening the vertical movement of the connecting sleeve on the support beam, thereby achieving fixed or sliding height of the crossbeam, making it convenient for the operator to adjust the height of the crossbeam up and down during installation.

[0006] The content of this application is used to briefly introduce concepts that will be described in detail in the detailed description section below. The content of this application is not intended to identify key features or essential features of the technical solution for which protection is sought, nor is it intended to limit the scope of the technical solution for which protection is sought.

[0007] To solve the technical problems mentioned in the background technology section above, some embodiments of the present application provide a height-adjustable exhibition hall truss, including:

[0008] A pair of support beams are vertically placed on the ground at intervals;

[0009] The height-adjustable exhibition hall trusses also include:

[0010] A connecting sleeve is slidably mounted on the supporting beam;

[0011] A crossbeam, provided on the connecting sleeve;

[0049] It should also be noted that, for ease of description, only the parts related to the invention are shown in the drawings. In the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0050] It should be noted that the concepts of "first" and "second" mentioned in this disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0051] It should be noted that the modifications of "one" and "multiple" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, they should be understood as "one or more".

[0052] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0053] Reference Figure 1-4 The height-adjustable exhibition hall truss 100 includes: a support beam 101, a connecting sleeve 102, a cross beam 103, a clamping block 104, and a tightening group 105; there are two support beams 101, which are erected on the ground, and there is a gap between the two support beams 101; the connecting sleeve 102 is slidably mounted on the support beam 101; the cross beam 103 is connected to the connecting sleeve 102 by bolts, and the connecting sleeves 102 are fixed at both ends of the cross beam 103, so that the two ends of the cross beam 103 are respectively connected to the two support beams 101 for vertical sliding connection; the clamping block 104 is slidably arranged on the connecting sleeve 102, and a plurality of slots 101a are opened on the support beam 101. The slots 101a are evenly spaced from top to bottom on the support beam 101 along the height direction of the support beam 101, and the card block 104 is embedded in the slot 101a; the tightening group 105 is arranged on the card block 104, and is used to tighten the card block 104, drive the card block 104 to move in the direction of the slot 101a, so that the card block 104 is stuck in the slot 101a, thereby fixing the connecting sleeve 102 on the support beam 101.

[0054] When installing and debugging the height of the beam 103, the operator puts the connecting sleeve 102 onto the support beam 101, and then adjusts the height of the beam 103 by sliding it up and down according to the required height of the beam 103. After confirming the height, the operator operates the tightening group 105 to drive the block 104 to be inserted into the slot 101a, thereby limiting the connecting sleeve 102 from sliding up and down on the support beam 101 and fixing the height position of the beam 103.

[0055] By setting the tightening group 105, the block 104 and the slot 101a, the height of the beam 103 can be adjusted multiple times during installation and debugging. Even after the beam 103 is fixed, the fixing of the connecting sleeve 102 can be cancelled by loosening the tightening group 105, and the height position of the beam 103 can be adjusted by sliding the beam 103 up and down.

[0056] An extension block 106 is fixed to the connecting sleeve 102 , and the extension block 106 horizontally surrounds the connecting sleeve 102 . A slide groove 106 a is provided on the extension sleeve. The slide groove 106 a is long and extends away from the connecting sleeve 102 . The clamping block 104 is slidably connected to the slide groove 106 a .

[0057] The height of the end of the slide groove 106a close to the connecting sleeve 102 is higher than the height of the end of the slide groove 106a away from the connecting sleeve 102, so that when the tightening group 105 is loosened, the block 104 slides away from the connecting sleeve 102 under the action of gravity.

[0058] The block 104 is composed of a sliding plate 104a, a connecting column 104b, a chuck 104c, and a limiting block 104d. The sliding plate 104a is slidably arranged in the sliding groove 106a. The sliding plate 104a is a circular plate, and the longitudinal section of the sliding groove 106a is T-shaped to facilitate the support and fixation of the sliding plate 104a; the connecting column 104b is integrally formed below the sliding plate 104a. The connecting column 104b is cylindrical and coaxial with the sliding plate 104a; the chuck 104c is integrally formed on the connecting column At the lower end of 104b, the chuck 104c is disc-shaped and coaxial with the connecting column 104b, and the chuck 104c is clamped into the slot 101a; the diameters of the sliding plate 104a and the chuck 104c are both larger than the diameter of the connecting column 104b; the limiting block 104d is fixed on the side wall of the connecting column 104b, and there is a gap between the middle of the limiting block 104d and the connecting column 104b, and the gap forms a through groove 104e, and the tightening group 105 penetrates into the through groove 104e.

[0059] The tightening group 105 includes: a tightening belt 105a and a tensioner 105b; the tightening belt 105a passes through the through slot 104e on the block 104 in sequence; the tensioner 105b is fixed to one end of the tightening belt 105a, and the tensioner 105b can adopt an adjustable binding belt tightening and locking mechanism and a tightening and locking mechanism in the binding belt disclosed in application number CN202410099508.5.

[0060] When it is necessary to fix the connecting sleeve 102, the operator tightens the tightening belt 105a by operating the tensioner 105b. The tightened tightening belt 105a drives the clamping block 104 to move toward the clamping slot 101a, and finally allows the clamping disc 104c to be embedded in the clamping slot 101a. The clamping slot 101a limits the up and down movement of the clamping disc 104c, thereby achieving the fixation of the connecting sleeve 102 and the beam 103, and finally fixing the height of the beam 103.

[0061] When it is necessary to cancel the lock on the up and down movement of the beam 103, the operator releases the tightener, the tightening belt 105a is loosened, and the sliding plate 104a slides downward under the guidance of gravity and the slide groove 106a, away from the support beam 101, and disengages from the slot 101a, thereby canceling the up and down sliding restriction of the connecting sleeve 102 and the beam 103.

[0062] The above structure can be used to adjust the height of the beam 103 and can also be used for pre-fixing the beam 103. If complete fixation is required, the beam 103 can be completely fixed to a limited height by structures such as bolts.

[0063] The above description is only an illustration of some preferred embodiments of the present disclosure and the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept. For example, the above-mentioned features are replaced with (but not limited to) technical features with similar functions disclosed in the embodiments of the present disclosure.
