Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

As shown in fig. 1 to 5, a portable building engineering drawing exhibition frame, including two I-shaped frames 1 and connect the connecting rod 2 between two I-shaped frames 1, I-shaped frame 1 comprises montant 11, sill bar 12 and ejector pin 13, connecting rod 2 comprises first pole 21 and second pole 22, ejector pin 13 and sill bar 12 are connected respectively to the both ends inboard of montant 11, the equal fixedly connected with first pivot 7 of sill bar 12 and ejector pin 13 outer wall, first pivot 7 rotates with montant 11 to be connected, and the both ends of first pole 21 and second pole 22 rotate with its corresponding sill bar 12 respectively to be connected.

As shown in fig. 1, the portable construction drawing rack in the present utility model is similar to the existing construction drawing rack structure, for example, the patent with publication number CN215423669U discloses an ancient construction drawing rack, which is mainly improved in that the rack is enabled to be overlapped, so that the portable construction drawing rack in the present utility model is convenient to carry, as shown in fig. 1 to 5, when a user needs to disassemble the i-shaped rack 1 and the connecting rod 2, the first rod 21 and the second rod 22 in the connecting rod 2 are separated first, the ejector rod 13 can be rotated by 90 degrees, then the vertical rod 11 is rotated by 90 degrees, and meanwhile, the ejector rod 13 is driven to rotate simultaneously with the vertical rod 11, so that the vertical rod 11 is parallel to the bottom rod 12 after rotating, and the first rod 21 is rotated again, so that the first rod 21 is rotated to be parallel to the vertical rod 11, and the ejector rod 13, the bottom rod 12 and the second rod 22 on the other side are operated according to the steps, at this time, the original difficult to disassemble and overlapped drawing rack is split into two separable components, and the portable drawing rack is further convenient to carry in an overlapping manner.

Through mutually supporting between montant 11, sill bar 12, ejector pin 13 and first pole 21, the second pole 22 for originally be difficult to dismantle, the drawing show shelf split of overlapping is two detachable subassemblies, and through the pivoted mode, realized overlapping, and then reduce the drawing show shelf and occupy the space when carrying, and then make to carry more convenient, increased the practicality of drawing show shelf.

As shown in fig. 1, 2, 3 and 4, the two vertical rods 11 are provided with sliding grooves 3, the sliding grooves 3 are connected with sliding blocks 6 in a sliding manner, and the first rotating shaft 7 is connected with the sliding blocks 6 in a rotating manner.

Specifically, after the ejector rod 13 and the bottom rod 12 rotate by 90 degrees, the bottom rod 12 and the ejector rod 13 can be pulled to slide relatively on the vertical rod 11, and meanwhile, the sliding blocks 6 on one sides of the ejector rod 13 and the bottom rod 12 are driven to slide relatively in the sliding grooves 3 in the vertical rod 11, so that the ejector rod 13 and the bottom rod 12 can be completely overlapped with the vertical rod 11, the overall length is shortened after rotation, and the convenience in carrying is further improved.

As shown in fig. 2, 3 and 5, one end of the first rotating shaft 7, which is far away from the bottom rod 12, is in threaded connection with a first threaded ring 5, and one side of the first threaded ring 5 abuts against the outer wall of the sliding block 6.

Specifically, before the operation of rotating the top rod 13 and the bottom rod 12, people need to unscrew the first threaded ring 5 for fixing the first rotating shaft 7, so that the bottom rod 12 and the top rod 13 can be rotated conveniently, and the post-rotation and sliding states of the top rod 13 and the bottom rod 12 can be realized by rotating the first threaded ring 5. The fixing of the top rod 13 and the bottom rod 12 on the inner side of the vertical rod 11 can be realized by the threaded connection of the first threaded ring 5 and the first rotating shaft 7.

As shown in fig. 2 and 5, two bottom rods 12 are fixedly connected with a connecting block 4 on a side far away from the sliding block 6, a rotating groove 41 is formed in the connecting block 4, a second rotating shaft 8 is rotationally connected in the rotating groove 41, the outer sides of the two second rotating shafts 8 are fixedly sleeved with a first rod 21 and a second rod 22 respectively, the second rotating shaft 8 penetrates through one end of the connecting block 4 and is externally connected with a second threaded ring 9 in a threaded manner, and the bottom surface of the second threaded ring 9 abuts against the top surface of the connecting block 4.

Specifically, after the user completes the adjustment of rotation and sliding of the top rod 13 and the bottom rod 12, one can rotate the second threaded ring 9 so that the inner wall of the second threaded ring 9 is separated from the top surface of the connecting block 4, at this time, the first rod 21 or the second rod 22 is rotated to 90 degrees in the rotation groove 41, so that the first rod 21 and the second rod 22 are horizontal to the vertical rod 11, and the first rod 21 or the second rod 22 coincides with the vertical rod 11, and thus, the convenience of carrying is further enhanced.

As shown in fig. 2, 4 and 5, the cross section of the slide 6 and the chute 3 is arranged in a cross-shaped manner. By setting the cross sections of the slide 6 and the chute 3 to be cross-shaped, the sliding of the slide 6 on the chute 3 can be made more stable.

As shown in fig. 5, the outer sides of the first thread ring 5 and the second thread ring 9 are provided with anti-skid threads. By arranging the anti-skid threads on the outer sides of the first thread ring 5 and the second thread ring 9, people can avoid slipping when rotating.

As shown in fig. 1 and 2, the first rod 21 and the second rod 22 are inserted and connected by bolts. Through setting up to pegging graft the setting between first pole 21 and the second pole 22, can make the reduction that can realize the distance between first pole 21 and the second pole 22, and utilize simple bolt fastening, the bolt is current mature technique, and the fixed mode is also simple convenient.
