Description

Technical Field

[0001] The utility model belongs to the technical field of musical instruments, and particularly relates to a piano with a cover which is easy to disassemble and assemble. Background Art

[0002] A cover is a protective device that covers the top of a piano speaker. It is usually made of a strong and durable material such as wood, plastic or metal. The top cover of a piano speaker is designed to protect the internal structure, electronic components and resonance chamber of the speaker, prevent the entry of foreign objects such as dust, dirt, debris, etc., and reduce the impact of external factors on the speaker.

[0003] When installing a cover for a small piano, traditional covers are often a whole piece of structure, and additional tools are needed to install the whole cover on top of the piano speaker, which makes the installation of the cover difficult, time-consuming and labor-intensive. In addition, since the whole cover is heavy, the installer may easily slip during installation, causing damage to the internal components of the speaker and causing damage to the piano.

[0004] Secondly, after long-term use, a large amount of dust tends to accumulate on the top of the shield of a small piano. If the shield needs to be maintained, the entire shield needs to be completely removed, making the maintenance and cleaning of the shield difficult. In addition, if the speaker needs to be repaired or adjusted, the lack of an easy-to-disassemble shield may increase the difficulty and risk of the maintenance work.

[0005] In summary, if the cover of a small piano is difficult to disassemble, it may cause dust accumulation and maintenance difficulties. Therefore, it is very important to set a cover that is easy to disassemble, so it is hoped to develop a piano with an easy-to-disassemble cover to solve the above problems. Utility Model Content

The structure of the left side of shield 1 120 and the right side of shield 2 130 are exactly the same and are arranged in a mirror-symmetrical manner. Shield 1 120 and shield 2 130 are both made of wood, and the width of shield 1 120 and shield 2 130 is greater than the distance between the two sets of baffles 170.

[0032] The connector 180 is composed of a shaft 200 , a limit block 190 , a sleeve 210 and a fixing plate 220 . The side of the shaft 200 close to the inner wall of the speaker 110 is fixed to the inner wall of the speaker 110 by bolts, and the side of the shaft 200 away from the inner wall of the speaker 110 is glued to the limit block 190 .

[0034] When it is necessary to inspect the internal components of the speaker 110, pinch the two sets of unlocking buttons 150 and move them to the left, thereby driving the two sets of locking plates 270 to move into the movable cavity through the two sets of connecting rods 2, thereby releasing the fixed state of the shield 120 and the shield 2 130, and then flip the shield 1 120 to the left and flip the shield 2 130 to the right, respectively, to open the top of the speaker 110, so as to facilitate the inspection of the internal components of the speaker 110.

[0035] The bottom of the telescopic cavity is connected to the top of the fixed groove 240, a group of partitions are arranged inside the telescopic cavity, a group of clamping plates 260 are arranged below the partitions, and two groups of springs 250 are arranged above the telescopic cavity.

[0036] The top of the spring 250 is connected and fixed to the top of the telescopic cavity. A group of connecting rods 1 are provided on the top of the partition. The top of the connecting rod 1 passes through the top of the telescopic cavity upward and is fixed to the bottom of the fixing button 140. The length and width of the bottom of the card plate 260 are smaller than the length and width of the card slot 230.

The positions of the locking plate 270 and the locking grooves 280 correspond to each other, and the locking plate 270 and the locking grooves 280 are connected with damping.

[0039] In actual use, push the two sets of unlocking buttons 150 to the right, so that the two sets of unlocking buttons 150 drive the two sets of connecting rods 2 to move to the right along the two sets of movable grooves 160, thereby driving the two sets of locking plates 270 to move to the right inside the two sets of movable cavities, and then insert the two sets of locking plates 270 to the right into the two sets of locking grooves 280, thereby completing the connection and fixation of baffle 1 120 and baffle 2 130, preventing external dust from entering the interior of the speaker 110 and causing damage to the strings. At the same time, it is easy to install, saving time and effort.

[0040] Example 1: Please refer to Figures 1 to 5 In actual use, first, an installation worker picks up the shield plate 120, and another worker flips the two groups of connectors 180 on the left side to align the two groups of fixing plates 220 with the two groups of fixing grooves 240, and then inserts the two groups of fixing plates 220 into the two groups of fixing grooves 240, and then vertically places the shield plate 120 and lifts it up slightly to keep the two groups of fixing plates 220 in the two groups of fixing grooves 240, and another worker pulls the two groups of fixing buttons 140 outward respectively, so that the fixing buttons 140 drive the partition to compress the two groups of springs 250 through the connecting rod 1 and make the springs 250 contract and store force, and this At this time, the card plate 260 moves into the telescopic cavity driven by the partition to expose the internal space of the fixed groove 240. At this time, the shield plate 120 is gently moved down to make the two sets of fixed plates 220 completely inserted into the bottom of the fixed groove 240. Then another worker loosens the two sets of fixing buttons 140, so that the spring 250 rebounds to push the card plate 260 into the fixed groove 240 and insert it into the card slot 230. Then, the shield plate 120 is flipped to the right, and the sleeve 210 rotates around the rotating shaft 200, so that the shield plate 120 is flipped to the top of the two sets of blocking bars 170, thereby completing the installation of the shield plate 120.

[0041] According to the above steps, baffle 2 130 is installed on the left side of baffle 1 120, thereby completing the installation of baffle 1 120 and baffle 2 130, and then push the two sets of unlocking buttons 150 to the right respectively, so that the two sets of unlocking buttons 150 drive the two sets of connecting rods 2 to move to the right along the two sets of movable grooves 160, thereby driving the two sets of locking plates 270 to move to the right inside the two sets of movable cavities, and then insert the two sets of locking plates 270 to the right into the two sets of locking grooves 280, thereby completing the connection and fixation of baffle 1 120 and baffle 2 130, preventing external dust from entering the interior of the speaker 110 and causing damage to the strings. At the same time, it is easy to install, saving time and effort.

[0042] Example 2: Please refer to Figures 1 to 5 When it is necessary to inspect the internal components of the speaker 110, it is only necessary to reverse the steps in Example 1 to move the two sets of locking plates 270 to the inside of the two sets of moving cavities, thereby releasing the fixed state of the shield 1 120 and the shield 2 130, and then flip the shield 1 120 to the left and flip the shield 2 130 to the right, respectively, so as to open the top of the speaker 110, so as to facilitate the inspection of the internal components of the speaker 110;

[0043] When it is necessary to clean and maintain the baffle 1 120 and the baffle 2 130, it is only necessary to reverse the steps in Example 1 to remove the baffle 1 120 and the baffle 2 130 from the top of the speaker 110, and then the baffle 1 120 and the baffle 2 130 can be maintained and cleaned. The final effect is that the baffle 1 120 and the baffle 2 130 are easy to disassemble and assemble, and maintenance and cleaning are convenient, and disassembly and assembly saves time and effort.
