Description

Technical Field

[0001] This utility model relates to the field of bamboo bookshelf technology, specifically a bamboo bookshelf that can be heightened. Background Technology

[0002] With the implementation of China's policies on banning logging in natural forests and returning farmland to forest, the contradiction between timber supply and demand has become increasingly tense, making the "bamboo-for-timber" approach feasible in some sectors. After the ban on logging in natural forests, China's timber supply will decrease by approximately 200 million cubic meters annually, resulting in a supply-demand gap of about 450 million cubic meters per year. Bamboo is highly renewable and has broad prospects for furniture applications.

[0003] Existing bamboo bookshelves are installed by splicing and bolting. During the bolt tightening process, at least one person is required to continuously hold the components steady to keep them aligned. This is labor-intensive and inconvenient. If the components are accidentally touched or subjected to uneven force during installation, the aligned components are prone to displacement or separation, requiring readjustment and significantly reducing installation efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a height-adjustable bamboo bookshelf to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a height-adjustable bamboo bookshelf, including a support frame, a placement board fixed to the inner side of the support frame, a connecting column fixed to the top of the support frame, a connecting groove opened at the bottom of the support frame, and stabilizing components and protective components provided on the surfaces of the support frame and the connecting column;

[0006] The stabilizing component includes:

[0007] The fixed cylinder is used to stabilize its internal mechanism;

[0008] The L-shaped rod is used to drive the movable plate and the locking block to move synchronously.

[0009] Card blocks are used in conjunction with card slots to achieve limit positioning.

[0010] Preferably, the fixing cylinder is fixed to the top of the inner wall of the docking groove. The support frame has an L-shaped groove inside. An L-shaped rod is provided inside the fixing cylinder. The end of the L-shaped rod away from the fixing cylinder passes through the fixing cylinder and the L-shaped groove, and the L-shaped rod is slidably connected to the fixing cylinder and the L-shaped groove. A spring is fixed to the top of the L-shaped rod. The top of the spring is fixed to the top of the inner wall of the L-shaped groove. A movable plate is hinged to the outer surface of the L-shaped rod. A locking block is hinged to the end of the movable plate away from the L-shaped rod. The end of the locking block away from the movable plate passes through the fixing cylinder, and the locking block is slidably connected to the fixing cylinder. The top of the docking column has a groove. The inner wall of the groove has a locking slot. When docking is required, the fixing cylinder is installed into the groove. Through the spring, the L-shaped rod, and the movable plate, the locking block enters the locking slot, which limits the mutual positioning between the support frames. It can then be installed normally by bolts without displacement or separation, and does not require long-term support, making bolt fixing convenient.

[0011] Preferably, the protective component includes a connecting block hinged to the end of the L-shaped rod away from the fixed cylinder. The outer surface of the support frame has a receiving groove, and the connecting block has a movable groove on the side away from the fixed cylinder. An L-shaped plate is slidably connected to the inner wall of the receiving groove. A second spring is fixed to the side of the L-shaped plate near the receiving groove, and the end of the second spring away from the L-shaped plate is fixed to the inner wall of the receiving groove. The receiving groove and the L-shaped groove are interconnected. The connecting block is located within the receiving groove, preventing accidental pulling of the connecting block from affecting the stability of the support frame. Pulling the L-shaped plate causes its surface to contact the inner wall of the movable groove, which in turn causes the connecting block to flip and grip, making it parallel to the L-shaped rod, allowing for normal upward pulling and easy disassembly.

[0012] Preferably, the end of the locking block away from the L-shaped rod is set as an inclined surface, so that when it is pressed, the locking block can move into the fixed cylinder without affecting normal docking.

[0013] Preferably, the movable plate is inclined, so that when the locking block moves, the movable plate can drive the L-shaped rod to move, and when the L-shaped rod moves, the movable plate can drive the locking block to move.

[0014] Preferably, both the support frame and the connecting column have mounting holes on their surfaces for easy fixing with bolts.

[0015] Compared with the prior art, this utility model provides a height-adjustable bamboo bookshelf with the following features:

[0016] Beneficial effects:

[0017] 1. This height-adjustable bamboo bookshelf, through its stabilizing components, allows for easy installation when the connecting posts are inserted into the connecting grooves. Simultaneously, the fixing cylinder enters the groove, and through the L-shaped rod, spring, and movable plate, the locking block enters the locking groove, thus limiting the mutual positioning of the support frames. It can be normally fixed with bolts without displacement or separation, and does not require long-term support, making bolt fixing convenient.

[0018] 2. This height-adjustable bamboo bookshelf, through its protective components, prevents accidental external pulling of the connecting block when it is located in the receiving groove, thus maintaining the stability of the support frame. When disassembly is required, remove the bolts, pull the L-shaped plate, and the surface of the L-shaped plate will contact the inner wall of the movable groove, causing the connecting block to flip. Personnel can then grasp the connecting block, making it parallel to the L-shaped rod, and pull it up normally, easily releasing the limit. Attached Figure Description

[0026] like Figures 1-6As shown, this utility model provides a technical solution: a height-adjustable bamboo bookshelf, including a support frame 1, a placement plate 2 fixed to the inner side of the support frame 1, a connecting column 3 fixed to the top of the support frame 1, a connecting groove 4 opened at the bottom of the support frame 1, and stabilizing components 5 and protective components 6 provided on the surfaces of the support frame 1 and the connecting column 3; the stabilizing component 5 includes: a fixed cylinder 50, an L-shaped rod 51, an L-shaped groove 52, a spring 53, a movable plate 54, a locking block 55, a groove 56, and a locking slot 57.

[0027] The fixed cylinder 50 is fixed to the top of the inner wall of the docking groove 4. An L-shaped groove 52 is provided inside the support frame 1. An L-shaped rod 51 is installed inside the fixed cylinder 50. The end of the L-shaped rod 51 away from the fixed cylinder 50 passes through the fixed cylinder 50 and the L-shaped groove 52, and the L-shaped rod 51 is slidably connected to the fixed cylinder 50 and the L-shaped groove 52. A spring 53 is fixed to the top of the L-shaped rod 51, and the top of the spring 53 is fixed to the top of the inner wall of the L-shaped groove 52. A movable plate 54 is hinged to the outer surface of the L-shaped rod 51. A locking block 55 is hinged to the end of the movable plate 54 away from the L-shaped rod 51. The end of the locking block 55 away from the movable plate 54 passes through the fixed cylinder 50, and the locking block 55 is slidably connected to the fixed cylinder 50. The top of the docking column 3... The part has a groove 56, and the inner wall of the groove 56 has a slot 57. The end of the locking block 55 away from the L-shaped rod 51 is set as an inclined surface. The movable plate 54 is set at an inclination. The fixed cylinder 50 enters the groove 56. The inner wall of the groove 56 abuts against the inclined surface of the locking block 55. The locking block 55 moves into the fixed cylinder 50. The movable plate 54 flips, driving the L-shaped rod 51 to move upward. The spring 53 is compressed. When the position of the locking block 55 is parallel to the slot 57, the spring 53 is released, the L-shaped rod 51 is reset, and the locking block 55 enters the slot 57 through the movable plate 54. This can limit the mutual positioning between the support frames 1, and can be installed normally by bolt fixing without displacement or separation. It also does not require long-term support and is convenient for bolt fixing.

[0028] The protective component 6 includes a connecting block 60, which is hinged to the end of the L-shaped rod 51 away from the fixed cylinder 50. The outer surface of the support frame 1 has a receiving groove 62. The side of the connecting block 60 away from the fixed cylinder 50 has a movable groove 61. An L-shaped plate 63 is slidably connected to the inner wall of the receiving groove 62. A second spring 64 is fixed to the side of the L-shaped plate 63 near the receiving groove 62. The end of the second spring 64 away from the L-shaped plate 63 is fixed to the inner wall of the receiving groove 62. The receiving groove 62 and the L-shaped groove 52 are interconnected. The connecting block 60 is located inside the receiving groove 62. The connecting block 60 will not be accidentally pulled from the outside, affecting the stability between the support frames 1. When it needs to be removed, the bolts are removed, and the L-shaped plate 63 is pulled. The surface of the L-shaped plate 63 abuts against the inner wall of the movable groove 61, which can drive the connecting block 60 to flip. Personnel can grab the connecting block 60 so that the connecting block 60 is parallel to the L-shaped rod 51, and then pull it up normally.

[0029] Both the support frame 1 and the connecting column 3 have mounting holes on their surfaces for easy bolt fixing.

[0030] When docking installation is required, docking post 3 is docked with docking groove 4, and fixing cylinder 50 enters groove 56. At this time, the inner wall of groove 56 abuts against the inclined surface of locking block 55. Locking block 55 moves into fixing cylinder 50, and movable plate 54 flips, causing L-shaped rod 51 to move upward. At the same time, spring 53 is compressed. When locking block 55 is parallel to locking groove 57, spring 53 is released, allowing L-shaped rod 51 to return to its original position. Through movable plate 54, locking block 55 enters locking groove 57, thus limiting the mutual positioning of support frames 1. At the same time, connecting block 60 is located in receiving groove 62, preventing accidental external pulling of connecting block 60. The stability between the support frame 1 and the mounting holes of the support frame 1 and the connecting column 3 are flush, so they can be fixed by bolts normally without displacement or separation. They do not require long-term support and are easy to fix with bolts. They can also be heightened according to actual use for convenience. When disassembly is required, the bolts are removed and the L-shaped plate 63 is pulled. At this time, the surface of the L-shaped plate 63 abuts against the inner wall of the movable groove 61, which can drive the connecting block 60 to flip. At this time, the personnel grab the connecting block 60 so that the connecting block 60 is parallel to the L-shaped rod 51, and can be pulled up normally. The movable plate 54 can be used to make the locking block 55 disengage from the locking groove 57, so that disassembly and separation can be carried out normally.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
