Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, in particular to a height-adjustable reinforced Z-shaped steel structure. Background Art

[0002] Z-shaped steel is a common cold-bent thin-walled steel. The processing material is roller (spray-painted) or galvanized. The existing Z-shaped steel is generally made by one-piece roller forming. After forming, there will be large internal stress, which may cause deformation or even breakage in subsequent use.

[0003] The existing patent with publication number CN215293127U proposes an adjustable height Z-shaped steel structure, which is achieved by arranging convex strips on the clamping plate and arranging a plurality of grooves matching the convex strips on the plate body. After the convex strips and the grooves are embedded and matched, only one bolt is needed to clamp the clamping plate on both sides of the plate body, thereby preventing the plate body and the clamping plate from moving. The height of the Z-shaped steel is adjusted in this way, but this method is relatively simple to adjust, and it is difficult to achieve height adjustment of the Z-shaped steel in different directions, which limits the height adjustment of the Z-shaped steel. At the same time, it is difficult to ensure the strength of the connection between the plate body by connecting with one bolt. Utility Model Content

[0004] The purpose of the utility model is to solve the above-mentioned technical problems and to propose a height-adjustable reinforced Z-shaped steel structure.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The connecting assembly includes a base plate and two vertical plates symmetrically arranged at the upper end of the base plate, the two vertical plates are provided with mounting grooves on opposite sides, a first slide plate is slidably arranged in the middle of the mounting groove, and second slide plates are slidably arranged on both sides of the mounting groove, the inner sides of the first slide plate and the second slide plate are respectively connected to the inner wall of the mounting groove through a spring compression rod, a plurality of transverse clips matching the clip slot are evenly distributed on the outer side of the first slide plate, and a plurality of vertical clips matching the clip slot are evenly distributed on the outer side of the second slide plate, a fixing block is fixedly arranged inside the mounting groove, a bidirectional screw rod is rotatably penetrated in the middle of the fixing block, and two extrusion blocks are symmetrically threadedly connected in the middle of the bidirectional screw rod, one side of the two extrusion blocks is in sliding contact with the inner wall of the mounting groove, and both ends of the bidirectional screw rod respectively pass through the outside of the mounting groove and are sleeved with anti-slip sleeves.

[0008] As a further description of the above technical solution:

[0009] The extrusion block is a trapezoidal block and a smaller end thereof is in sliding contact with the first slide plate and the second slide plate.

[0010] As a further description of the above technical solution:

[0011] The horizontal clamping strip and the vertical clamping strip are sawtooth-shaped.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0013] In the utility model, by providing a horizontal clamping strip, a vertical clamping strip and a clamping slot, the bidirectional screw rod is rotated to drive the extrusion block to move, and the extrusion block is switched to contact and extrude with the first slide plate and the second slide plate, so that the plate body can be adjusted horizontally and vertically. When the extrusion block squeezes the first slide plate and the second slide plate at the same time, the horizontal clamping strip and the vertical clamping strip are both stuck in the clamping slot, which effectively ensures the stability of the plate body connection.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Embodiment 1:

[0021] As shown in 1-4, a height-adjustable reinforced Z-shaped steel structure includes a plate body 1, the plate bodies 1 are two in number and are L-shaped, the two plate bodies 1 are detachably combined into a Z-shaped steel structure, the outer surfaces of the two plate bodies 1 are provided with card slots 4 on both sides, the card slots 4 are crisscrossed, and the two plate bodies 1 are connected and matched by a connecting assembly;

[0022] The connecting assembly includes a bottom plate 2 and two vertical plates 3 symmetrically arranged at the upper end of the bottom plate 2, and a mounting groove is opened on the opposite side of the two vertical plates 3. A first slide plate 8 is slidably arranged in the middle of the mounting groove, and a second slide plate 9 is slidably arranged on both sides of the mounting groove. The inner sides of the first slide plate 8 and the second slide plate 9 are respectively connected to the inner wall of the mounting groove through a spring compression rod 12. A plurality of transverse clip strips 10 matching the card slot 4 are evenly distributed on the outer side of the first slide plate 8, and a plurality of vertical clip strips 11 matching the card slot 4 are evenly distributed on the outer side of the second slide plate 9. A fixing block 5 is fixed inside the mounting groove, and a bidirectional screw rod 6 is rotatably penetrated in the middle of the fixing block 5, and a symmetrical threaded connection sleeve is provided in the middle of the bidirectional screw rod 6. Two extrusion blocks 7, one side of the two extrusion blocks 7 is in sliding contact with the inner wall of the installation groove, the two ends of the bidirectional screw rod 6 respectively pass through the outside of the installation groove and are covered with anti-slip sleeves, and the bidirectional screw rod 6 is rotated to drive the two extrusion blocks 7 to move. When the extrusion block 7 squeezes the first slide plate 8 but not the second slide plate 9, the two plate bodies 1 can be adjusted laterally at this time. When the extrusion block 7 squeezes the second slide plate 9 but not the first slide plate 8, the two plate bodies 1 can be adjusted longitudinally at this time. When the extrusion block 7 squeezes the first slide plate 8 and the second slide plate 9 at the same time, the horizontal clamping strip 10 and the vertical clamping strip 11 are both stuck in the clamping slot 4, and the plate body 1 cannot move, thereby ensuring the stability of the connection of the plate body 1.

[0023] Furthermore, the extrusion block 7 is a trapezoidal block and its smaller end is in sliding contact with the first slide 8 and the second slide 9, so that during the movement of the extrusion block 7, the inclined surface of the extrusion block 7 contacts and squeezes the first slide 8 or the second slide 9, pushing the first slide 8 and the second slide 9 to move.

[0024] Furthermore, the transverse clamping strip 10 and the vertical clamping strip 11 are serrated, which effectively ensures the stability of the transverse clamping strip 10 and the vertical clamping strip 11 being clamped in the clamping slot 4, thereby ensuring the firmness of the connection between the two plate bodies 1.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
