[0002] In the field of metal space frame installation, such as building curtain walls and equipment protection nets, adjustable support structures are widely used because they can adapt to the needs of different installation scenarios. Traditional metal space frame support structures usually adopt the following two forms: one is a rigid connection structure in which support rods with through holes are fixed to connecting sleeves by bolts; the other is a telescopic adjustment structure in which slide rails are set in conjunction with locking devices.

[0003] In existing metal space frame support structures, the adjustment holes of the support rods and connecting sleeves are mostly arranged coaxially, which can only achieve axial length adjustment and cannot adjust the installation angle of the support structure according to the installation angle of the space frame, thus affecting construction efficiency. Utility Model Content

[0005] The present invention proposes an adjustable metal mesh support structure, including two clamping components, a support rod, two connecting sleeves, reinforcing ribs, and several fixed shafts. The two connecting sleeves are respectively symmetrically sleeved on the two ends of the support rod. Each connecting sleeve and the outer wall of the support rod are provided with equal-spaced and corresponding adjustment holes for adjusting the relative position between the connecting sleeve and the support rod. The axes of two adjacent adjustment holes are perpendicular to each other.

[0006] The reinforcing ribs are integrally formed in a spiral shape on the outer surface of each connecting sleeve, and a spiral groove is formed between the reinforcing ribs and the outer wall of the connecting sleeve. The adjustment holes on the connecting sleeve are arranged along the extension direction of the spiral groove.

[0007] Several fixed shafts are respectively inserted into the adjustment holes aligned on the corresponding connecting sleeve and support rod, which are used to fix the connecting sleeve and support rod at the selected position;

[0008] Two clamping components are respectively set at the ends of the corresponding connecting sleeves to clamp and fix the metal mesh frame.

[0009] Preferably, the clamping assembly includes a second clamp, the inner wall of which is fixedly connected to a rotating shaft, and the outer wall of which is rotatably connected to a first clamp.

[0010] Preferably, the clamping assembly further includes a bolt, the outer wall of the second clamp has a first through hole, the outer wall of the first clamp has a second through hole, the end of the bolt passes through the first through hole and the second through hole and extends to its outer side, and the outer wall of the bolt is threaded with a nut.

[0011] Preferably, the inner wall of the second through hole is provided with a groove, and the bolt head is located in the groove.

[0012] Preferably, the outer wall of the second jacket is provided with a sliding groove, the inner wall of the sliding groove is fixedly connected to a fixing plate, an arc rod is fixedly connected between the second jacket and the fixing plate, a sliding plate is slidably connected to the outer wall of the arc rod, and a first spring is sleeved on the outer wall of the arc rod.

[0013] Preferably, one end of the first spring is fixedly connected to the second sleeve, and the other end of the first spring is fixedly connected to the fixing plate.

[0014] Preferably, the outer wall of the skateboard is fixedly connected with a plurality of limiting plates, which are used to limit the two opposing planes of the nut.

[0015] Preferably, a support plate is fixedly connected to the outer wall of the skateboard, a locking rod is slidably connected to the inner wall of the support plate, a second spring is sleeved on the outer wall of the locking rod, a pull ring is fixedly connected to the end of the locking rod, a positioning hole is opened on the outer wall of the bolt, and the end of the locking rod is inserted into the positioning hole.

[0016] Preferably, one end of the second spring is fixedly connected to the support plate, and the other end of the second spring is fixedly connected to the end of the pull ring.

[0017] The beneficial effects of this utility model, achieved through the above technical solution, are as follows:

[0018] 1. In this utility model, the connecting sleeve can rotate relative to the support rod, and both the connecting sleeve and the support rod have equal-spaced and corresponding adjustment holes on their outer walls, with the axes of two adjacent adjustment holes perpendicular to each other; by rotating the connecting sleeve, the position of the adjustment holes can be easily adjusted according to the clamping angle of the clamping component, thereby changing the angle of the support structure to adapt to the installation requirements of different space frames. At the same time, the equal-spaced adjustment holes can facilitate adaptive adjustment of the length of the support rod.

[0019] 2. In this utility model, two reinforcing ribs are integrally formed on the outer periphery of the corresponding connecting sleeves, and a spiral groove is formed between the reinforcing ribs and the outer wall of the connecting sleeve. The adjustment holes on the connecting sleeve are arranged along the extension direction of the spiral groove. The spiral reinforcing structure can enhance the structural strength of the connecting sleeve, disperse stress, and improve the overall load-bearing capacity and deformation resistance of the supporting structure.

[0020] 3. The slot limits the bolt head to prevent the bolt from rotating and ensures the fastening effect. The limiting plate limits both sides of the nut to prevent the nut from loosening under vibration or external force and improves the stability of clamping.

[0021] 4. By pulling the pull ring upward, the clamping rod moves upward. Under the elastic force of the second spring, the end of the clamping rod is inserted into the positioning hole on the bolt. This design can position the bolt and prevent it from rotating during long-term use, ensuring the long-term stability of the clamping structure. Attached Figure Description
