Description

Technical Field

[0001] The utility model relates to the field of building construction equipment, in particular to a material rack for building construction. Background Art

[0002] Material racks for construction are temporary structures used at construction sites to store, keep and manage construction materials, tools and equipment. They are essential to improving construction efficiency, ensuring construction safety and reducing the risk of accidents. Material racks are used to store various construction materials such as pipes, blocks, steel bars, wood, tools and other small items to ensure that the construction site is neat and orderly. Usually, after the material racks are loaded with materials, the two material racks in each group need to be stacked for easy transportation.

[0003] When two existing material racks for construction are stacked, the two adjacent material racks are usually fixed by bolts to ensure the stability of the two materials during transportation. When the staff use a forklift to move and split the two stacked material racks, the staff needs to remove several bolts, which makes the installation or splitting process time-consuming and labor-intensive, and not convenient enough. Based on this, we propose a material rack for construction. Utility Model Content

A support leg 3 is fixedly connected to the bottom of each support frame 1 corresponding to the support column 2, and also includes a positioning mechanism, a clamping mechanism and a moving mechanism. A clamping mechanism is provided on the top of each support column 2, and a positioning mechanism is provided at the bottom of each support leg 3. Each positioning mechanism is connected to the corresponding clamping mechanism. A moving mechanism is provided inside each support column 2, and the moving mechanism is used to release the connection between the clamping mechanism and the positioning mechanism. A limiting member is provided on the top of the support column 2 close to the side of the moving mechanism.

[0025] In this embodiment, a diagonal brace is provided between each support column 2 and the support frame 1 to ensure the stability of the support column 2. An upwardly convex connecting column is provided at the bottom of each support leg 3, and the connecting column is fixedly connected to the support frame 1.

[0026] The positioning mechanism and the clamping mechanism cooperate to facilitate the connection of two stacked support frames 1, and the moving mechanism and the limiter can conveniently release the connection between the two support frames 1, making it convenient for the staff to move the upper support frame 1 with a forklift.

[0027] Furthermore, the positioning mechanism includes a guide hole 4, which is opened at the bottom of the support leg 3, and two positioning holes 5 are opened on the inner wall of the guide hole 4. The two positioning holes 5 are symmetrically arranged to facilitate the support column 2 located at the bottom to be embedded in the guide hole 4 located at the bottom of the support leg 3 located at the top, and to lock the two support frames 1. Furthermore, the port surrounding the guide hole 4 is provided with a rounded corner.

[0028] Furthermore, the clamping mechanism includes two positioning rods 8, and a first mounting groove 6 is opened at the top of the support column 2. The two positioning rods 8 slide through the support column 2 and extend to the inside of the first mounting groove 6. One end of the two positioning rods 8 located in the first mounting groove 6 is fixedly connected to the limiting plate 9. A support spring 10 is sleeved on the outside of the positioning rod 8. One end of the support spring 10 is fixedly connected to the inner wall of the first mounting groove 6, and the other end is fixedly connected to the limiting plate 9. The support spring 10 is a tension spring. Through the action force of the support spring 10, the positioning rod 8 can be conveniently embedded in the positioning hole 5.

[0029] Furthermore, the moving mechanism includes two guide blocks 12, a slide plate 11 is slidably connected inside the support column 2 and located below the clamping mechanism, a moving hole 7 is opened on one side of the support column 2, the bottom ends of the two guide blocks 12 are fixedly connected to the slide plate 11, a placement groove 13 is opened on the top of the guide blocks 12, and the tops of the opposite sides of the two guide blocks 12 are provided with rounded corners, a grip rod 20 is fixedly connected to one side of the slide plate 11, the free end of the grip rod 20 can slide through the moving hole 7 and extend out, a clamping block 21 is fixedly connected to one side of the grip rod 20, the clamping block 21 is located on the outside of the support column 2, and the slide plate 11 is slidably connected to the inside of the first mounting groove 6.

[0030] Furthermore, the limiting member includes an extrusion plate 18, and a second mounting groove 14 is provided on the top of the support column 2 near the moving hole 7. A fixing rod 15 is fixedly connected inside the second mounting groove 14, and a slider 17 is slidably connected to the outer wall of the fixing rod 15. A limiting spring 16 is sleeved on the outer side of the fixing rod 15, and one end of the limiting spring 16 is fixedly connected to one side of the slider 17, and the other end is fixedly connected to the inner wall of the second mounting groove 14. The limiting spring 16 is in a compressed state, and the extrusion plate 18 is fixedly connected to the slider 17. Two card slots 19 are provided on the side of the extrusion plate 18 near the grip 20. Through the action of the limiting spring 16, the card slot 19 on one side of the extrusion plate 18 is conveniently driven to be sleeved outside the card block 21.

[0031] Furthermore, the clamping block 21 is adapted to the inside of the two clamping slots 19 , and the clamping block 21 is embedded in the inside of the clamping slots 19 , so as to limit and fix the position of the handle 20 .

[0032] When the top of the support leg 3 is completely embedded in the guide hole 4 and the positioning rod 8 is aligned with the positioning hole 5, the reaction force of the support spring 10 drives the positioning rod 8 to be embedded in the positioning hole 5, so that the lower support column 2 and the upper support leg 3 are fixed, thereby conveniently completing the stacking of the two support frames 1. At this time, the clamping block 21 on the outer wall of the gripping rod 20 extends into the clamping groove 19 at the lower part of the extrusion plate 18, thereby limiting and fixing the position of the slide plate 11.

[0033] In addition, the squeezing plate 18 is pushed in the direction away from the gripping rod 20, so that the squeezing plate 18 drives the sliding block 17 to slide on the fixing rod 15. At this time, the limiting spring 16 is compressed, and the slot 19 at the lower part of the squeezing plate 18 is separated from the snap-in block 21, thereby releasing the restriction on the slide plate 11, and pushing the gripping rod 20 upward, so that the gripping rod 20 drives the slide plate 11 to slide upward inside the first mounting groove 6, and the slide plate 11 drives the outer walls of the two guide blocks 12 to contact the bottom of the two limit plates 9 respectively. At this time, the bottom of the limit plate 9 is pushed by the guide block 12, so that the two limit plates 9 are close to each other. After the positioning rod 8 is separated from the positioning hole 5, the squeezing plate 18 is released, so that the snap-in block 21 on the gripping rod 20 extends into the slot 19 at the upper part of the squeezing plate 18, thereby limiting the position of the slide plate 11 again, making it convenient to release the restriction and fixation of the two support frames 1, and convenient for the staff to move the upper support frame 1 with a forklift.
