Technical Field

[0001] This utility model relates to the technical field of musical instruments, and in particular to a folding piano. Background Technology

[0002] Folding pianos reduce their length by folding, making them easier to store and carry. Currently, the folding function of folding pianos is achieved through hinges extending from the bottom shell and fixing hooks extending from the top shell. These mechanisms have weaknesses in strength and are prone to damage. After long-term use, the latches between the left and right sides of the piano may become less secure. In addition, the connecting wires between the left and right sides of the folding piano are exposed, which not only affects the aesthetics but also makes it susceptible to accidental damage such as collisions and pulling. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a folding piano with good folding stability, not easy to be damaged and able to hide the connecting wires.

[0004] The technical solution adopted by this utility model is as follows: This utility model includes a first instrument body and a second instrument body rotatably connected to the first instrument body. The inner side of the second instrument body is provided with an installation port, and a hook body is rotatably connected to the installation port. The first instrument body is provided with a locking member and a first elastic member. The first elastic member is disposed on the locking member. The locking member has a locking end. The inner side of the first instrument body is provided with an opening corresponding to the locking member. The hook body can extend into the opening and engage with the locking end. The locking end is locked on the hook body when the first elastic member pushes the locking member to move in a first direction. The locking end disengages from the hook body when the locking member is pushed to move in a second direction.

[0005] Furthermore, the folding piano also includes a connecting wire. A first hinge component is provided on the inner side of the first piano body, and a second hinge component is provided on the inner side of the second piano body, which abuts against the first hinge component. Both the first hinge component and the second hinge component are provided with wiring channels. The two wiring channels are connected and respectively connected to the first piano body and the second piano body. One end of the connecting wire is connected to the first piano body, and the other end of the connecting wire passes through the two wiring channels in sequence and is connected to the second piano body.

[0006] Furthermore, the locking element is installed in the first instrument body via a first bracket.

[0007] Furthermore, the hook is installed in the second instrument body via a second bracket, and the second bracket is provided with a second elastic element that abuts against the hook.

[0008] Furthermore, a first hinge is connected between the first bracket and the second bracket, and the first hinge is located on the inner side of the first instrument body and the inner side of the second instrument body.

[0009] Furthermore, a second hinge is connected between the inner side of the first body and the inner side of the second body, and both the first hinge component and the second hinge component are located between the first hinge and the second hinge.

[0010] Furthermore, the end of the locking member is exposed at the bottom of the first instrument body.

[0011] Furthermore, the locking member includes a locking body, on which a locking slot is provided, and the locking end is formed at the upper end of the locking slot. The upper end of the first elastic member abuts against the first instrument body, and the lower end abuts against the locking body. The lower end of the locking body is exposed at the bottom of the first instrument body.

[0012] Furthermore, the upper end of the lock is provided with an inclined guide surface, which is used to guide the hook body.

[0013] Furthermore, the hook body is rotatably connected to the mounting port via a hook body pivot. When the hook body is folded in the mounting port, the end face of the hook body is flush with the inner side of the second instrument body. When the hook body is opened, the length direction of the hook body is parallel to the length direction of the second instrument body.

[0014] The beneficial effects of this utility model are:

[0015] In contrast to the shortcomings of existing technologies, this invention utilizes a first elastic element to securely engage the locking end with the hook body, enabling the folding piano to close. Furthermore, pushing the locking element facilitates the release of the connection between the locking end and the hook body. The hook body can rotate into the mounting opening during folding for easy storage and protection, preventing damage. Additionally, the absence of a connecting shaft between the first and second hinge components allows for efficient use of the saved mounting space for wiring, enabling the connecting wires to pass through the piano body and avoiding exposure. This not only enhances the aesthetics of the folding piano but also prevents accidental damage to exposed connecting wires.

[0033] like Figures 1 to 5 As shown, in this embodiment, the present invention includes a first instrument body 1 and a second instrument body 2 rotatably connected to the first instrument body 1. The inner side of the second instrument body 2 is provided with a mounting opening 3, and a hook 5 is rotatably connected to the mounting opening 3. The first instrument body 1 is provided with a locking member 6 and a first elastic member 7. The first elastic member 7 is disposed on the locking member 6, and the locking member 6 has a locking end 8. The inner side of the first instrument body 1 is provided with an opening 9 corresponding to the locking member 6. The hook 5 can extend into the opening 9 and engage with the locking end 8. The locking end 8 locks onto the hook 5 when the first elastic member 7 pushes the locking member 6 to move in a first direction, and disengages from the hook 5 when the locking member 6 is pushed to move in a second direction. The first and second directions are opposite; for example, when the first direction is downward, the second direction is upward. The first elastic member 7 is a spring.

[0034] When the folding piano is folded, the locking member 6 is manually pushed to move in the second direction to compress the first elastic member 7. At this time, the locking end 8 is disengaged from the hook body 5, so that the first piano body 1 and the second piano body 2 can be released and separated. At this time, the locking member 6 is reset under the elastic force of the first elastic member 7, and the first piano body 1 is rotated relative to the second piano body 2 to realize the folding of the folding piano.

[0035] When the folding piano is closed, by inserting the hook 5 into the opening 9 and pressing the locking end 8, the locking end 8 moves in the second direction until the hook 5 is locked by the locking end 8. Due to the action of the first elastic element 7, the locking end 8 can be firmly locked onto the hook 5. At this time, the first piano body 1 and the second piano body 2 are closed.

[0036] The hook 5 can be rotated into the mounting opening 3 for easy storage and protection, which can prevent damage to the hook 5 when the folding piano is folded; the hook 5 can be rotated and extended out of the mounting opening 3, so that it can be engaged with the locking end 8 to close the folding piano.

[0037] Compared with the shortcomings of the prior art, in this utility model, the first elastic element 7 is provided so that the locking end 8 can be firmly locked onto the hook body 5 to realize the folding piano. Moreover, by pushing the locking element 6, the connection between the locking end 8 and the hook body 5 can be easily released. In addition, the hook body 5 can rotate into the mounting opening 3 when the folding piano is folded for easy storage and protection, which can avoid damage to the hook body 5. Therefore, this utility model has the advantages of good folding stability and not being easily damaged.

[0038] like Figure 6 As shown, in some embodiments, the folding piano further includes a connecting wire 10. A first hinge member 11 is provided on the inner side of the first piano body 1, and a second hinge member 12 is provided on the inner side of the second piano body 2, which abuts against the first hinge member 11. Both the first hinge member 11 and the second hinge member 12 are provided with a wiring channel 13. The two wiring channels 13 are connected and respectively connected to the first piano body 1 and the second piano body 2. One end of the connecting wire 10 is connected to the first piano body 1, and the other end of the connecting wire 10 passes through the two wiring channels 13 in sequence and is connected to the second piano body 2. Specifically, by eliminating the connecting shaft between the first hinge member 11 and the second hinge member 12, the saved installation space of the shaft is used for wiring, allowing the connecting wire 10 to pass through the inside of the piano body, thus avoiding the exposure of the connecting wire 10. This not only improves the aesthetic appearance of the folding piano but also prevents the exposed connecting wire 10 from being accidentally damaged, thereby enhancing the safety of the folding piano. This invention has the advantage of being able to hide the connecting wire.

[0039] like Figures 7 to 10As shown, in some embodiments, the locking member 6 is installed in the first instrument body 1 via a first bracket 15; the hook 5 is installed in the second instrument body 2 via a second bracket 16, and the second bracket 16 is provided with a second elastic member 17 that abuts against the hook 5. Specifically, when the hook 5 rotates to the outside of the mounting opening 3, the hook 5 can be perpendicular to the inside of the second instrument body 2. Due to the elastic force of the second elastic member 17, the hook 5 can maintain this perpendicular state, so as to prevent the hook 5 from disengaging from the locking end 8 due to its own rotation; similarly, when the hook 5 rotates into the mounting opening 3, the elastic force of the second elastic member 17 can also keep the hook 5 in a folded state.

[0040] like Figure 4 , Figures 6 to 10 As shown, in some embodiments, a first hinge 18 connects the first support 15 and the second support 16, with the first hinge 18 located on the inner side of the first instrument body 1 and the inner side of the second instrument body 2; a second hinge 19 connects the inner side of the first instrument body 1 and the inner side of the second instrument body 2, with the first hinge member 11 and the second hinge member 12 both located between the first hinge 18 and the second hinge 19. Both the first hinge 18 and the second hinge 19 are alloy hinges. Specifically, both the first hinge 18 and the second hinge 19 are hinged using pivots, eliminating the need for wiring. The stability of the first instrument body 1 and the second instrument body 2 during hinged connection is ensured by positioning the first hinge member 11 and the second hinge member 12 between the first hinge 18 and the second hinge 19.

[0041] like Figure 3 , Figures 8 to 10 As shown, in some embodiments, the end of the locking member 6 is exposed at the bottom of the first instrument body 1; the locking member 6 includes a locking body 20, on which a locking opening 21 is provided, and the locking end 8 is formed at the upper end of the locking opening 21. The upper end of the first elastic member 7 abuts against the first instrument body 1, and the lower end abuts against the locking body 20. The lower end of the locking body 20 is exposed at the bottom of the first instrument body 1; the upper end of the locking opening 21 is provided with an inclined guide surface 22, which is used to guide the hook 5. Specifically, by manually pushing the locking member 6 located at the bottom of the first instrument body 1, the connection between the hook 5 and the locking end 8 is released; in addition, the inclined guide surface 22 facilitates the insertion of the hook 5 into the locking opening 21 to press the locking end 8.

[0042] like Figures 3 to 5 , Figure 7As shown, in some embodiments, the hook 5 is rotatably connected to the mounting opening 3 via a hook shaft 23. When the hook 5 is folded in the mounting opening 3, its end face is flush with the inner side of the second instrument body 2, and its length direction is parallel to the length direction of the second instrument body 2 when the hook 5 is open. Specifically, the arrangement of the end face of the hook 5 being flush with the inner side of the second instrument body 2 when folded in the mounting opening 3 is not only aesthetically pleasing but also helps prevent damage to the hook 5.

[0043] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
