DETAILED DESCRIPTION

[0023] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of an easy-to-install piano bridge of the utility model in conjunction with the accompanying drawings.

[0024] See also Figure 1-5 The utility model is a piano bridge that is easy to install, comprising a piano body 1, a bridge body 2 and two groups of fixing bolts 3. The bottom surface of the bridge body 2 contacts the inner bottom wall of the piano body 1. The bottom end of each fixing bolt 3 penetrates the bridge body 2 and extends to the inside of the piano body 1. A threaded rod 4 is fixedly installed on the top of each fixing bolt 3. A threaded sleeve 5 is threadedly connected to the outer surface of each threaded rod 4. The top of each threaded sleeve 5 penetrates the bridge body 2 and is fixedly installed with a first connecting wheel 6. The outer surface of each group of first connecting wheels 6 is sleeved with a first belt 7, wherein the tops of the two first connecting wheels 6 are fixedly installed with second connecting wheels 8, and the outer surfaces of the two second connecting wheels 8 are jointly sleeved with a second belt 9.

[0025] Two sets of supporting legs 10 are fixedly installed on the bottom surface of the piano body 1, and a universal wheel 11 is fixedly installed on the bottom surface of each supporting leg 10. The installation of the supporting legs 10 and the universal wheel 11 facilitates the user to move the piano body 1, thereby increasing the convenience of moving the piano body 1.

[0026] A piano cover 12 is movably hinged on the upper surface of the piano body 1, and a pull rod 13 is fixedly installed on the upper surface of the piano cover 12. The installation of the piano cover 12 allows the user to use the piano cover 12 to shield the bridge body 2 when the piano body 1 is not in use, thereby minimizing the bridge body 2 from external collisions, thereby providing a certain degree of protection for the bridge body 2. The installation of the pull rod 13 makes it convenient for workers to open the piano cover 12, thereby facilitating the installation and maintenance of the bridge body 2.

[0027] A connecting bearing 14 is fixedly installed on the outer surface of each threaded sleeve 5. The outer surface of each connecting bearing 14 is fixedly connected to the inner wall of the code bridge body 2. The outer ring of the connecting bearing 14 is fixedly connected to the code bridge body 2, and the inner ring of the connecting bearing 14 is fixedly connected to the threaded sleeve 5. The installation of the connecting bearing 14 stabilizes the threaded sleeve 5, thereby minimizing the phenomenon of the threaded sleeve 5 moving up and down during rotation, thereby ensuring the stability of the threaded sleeve 5.

[0028] A connecting column 15 is fixedly installed on the upper surface of one of the second connecting wheels 8, and a pull ring 16 is rotatably connected inside the connecting column 15. The installation of the connecting column 15 and the pull ring 16 makes it convenient for workers to rotate the second connecting wheel 8, thereby reducing the complexity of the workers' operation and increasing the convenience of the workers in rotating the second connecting wheel 8.

[0029] A connecting block 17 is fixedly installed on the bottom surface of the piano cover 12, and a clamping block 18 is fixedly installed on the inner bottom wall of the piano body 1. The connecting block 17 and the clamping block 18 are clamped with a support rod 19 inside. The support rod 19 is clamped inside the connecting block 17 and the clamping block 18, so as to support the piano cover 12. When workers install the bridge body 2, there is no need for workers to support the piano cover 12, thereby increasing the convenience of workers during installation.

[0030] A storage box 20 is fixedly installed on the bottom surface of the piano body 1, and a bench 21 is arranged inside the storage box 20. The bottom surface of the bench 21 contacts the inner bottom wall of the storage box 20. The setting of the bench 21 is convenient for users to use when playing the piano, thereby increasing the practicality of the device. The installation of the storage box 20 plays the role of storing the bench 21.

[0031] A locking block 22 and a locking frame 23 are fixedly installed on the right side of the placement box 20, and the locking block 22 is clamped in the inside of the locking frame 23. The installation of the locking block 22 and the locking frame 23 plays a role in locking the placement box 20, thereby avoiding the placement box 20 from opening by itself as much as possible, thereby ensuring the stability of the placement box 20.

[0032] The working principle of the utility model is as follows: first, the worker pulls the pull rod 13 to open the piano cover 12, and then the worker clamps the support rod 19 inside the connecting block 17 and the clamping block 18 to support the piano cover 12, so as to facilitate the worker to install the bridge body 2. When the worker installs the bridge body 2, the worker first applies flat glue on the bottom surface of the bridge body 2, and then uses the flat glue to adhere the bridge body 2 to the inner bottom wall of the piano body 1, and the worker rotates the pull ring 16, so that the pull ring 16 drives the connecting column 15 to rotate, so that the connecting column 15 drives the connecting column 15 connected to it. The second connecting wheel 8 connected to it rotates, and then the second connecting wheel 8 drives the first connecting wheel 6 connected to it to rotate. At the same time, the second connecting wheel 8 and the first connecting wheel 6 respectively drive the second belt 9 and the first belt 7 to rotate. Therefore, driven by the first belt 7 and the second belt 9, the two groups of threaded sleeves 5 start to rotate, and then the two groups of threaded sleeves 5 drive the threaded rod 4 to move downward and rotate, so that the threaded rod 4 screws the fixing bolts 3 into the interior of the piano body 1, completing the installation process of the bridge body 2, so that there is no need for workers to repeatedly rotate multiple fixing bolts 3, thereby increasing the installation efficiency of workers.
