[ detailed description ] of the utility model
The utility model is further described below with reference to the accompanying drawings:
as shown in fig. 1 to 6, the utility model provides a portable piano finger training device, which comprises two foldable or detachable shells 1, wherein a plurality of inserting grooves 11 are formed in each shell 1, a storage space 100 is defined between the two shells 1, and a plurality of knocking keys 2 for pressing and knocking by fingers are placed in the storage space 100.
When the piano is used, the two shells 1 which are connected with each other are separated, then the knocking piece 2 in the storage space 100 of the shells 1 is taken out, the inserting groove 11 of the shells 1 is upwards placed on a desktop, then the knocking piece 2 is inserted into the inserting groove 11 of the shells 1, a child can train piano fingers, the piano is very convenient to use, and the two shells 1 can be conveniently placed in a schoolbag after being folded, so that the piano is convenient to carry. Of course, the rapper 2 is not easily lost when placed in the housing 1.
The inside of the shell 1 is provided with a groove 12, the shell 1 is provided with a clamping groove 13 which is positioned in the groove 12 and can be used for placing the knocking key 2, and the storage space 100 is surrounded by the two grooves 12 of the shell 1. The clamping groove 13 is convenient for the fixed joint of the knocking member 2, can not fall off, and is convenient for placing the knocking member 2.
The two shells 1 are provided with the magnets 3, the two shells 1 are folded through the magnets 3, so that the two shells 1 are convenient to connect and fix with each other, and meanwhile, the two shells are convenient to separate.
The top end of the inserted link 22 is also provided with an anti-slip piece 4 made of plastic. The slip prevention member 4 prevents the exerciser's fingers from slipping when pressing the insert 2, thereby improving the exercise effect.
The clamping grooves 13 and the inserting grooves 11 are arranged in a staggered manner; the clamping groove 13 comprises four transverse grooves 131 and two longitudinal grooves 132. The clamping grooves 13 and the inserting grooves 11 are arranged in a staggered mode, so that the structure of the shell 1 is compact, the knocking keys 2 are conveniently placed, the corresponding training is convenient for children due to the arranged inserting grooves 11, and the size is smaller.
The number of the inserting grooves 11 is 7, the four inserting grooves 11 are arranged on the same straight line, one inserting groove 11 is arranged on the front sides of the four inserting grooves 11, and the other two inserting grooves 11 are arranged at two ends of the shell 1 and on the rear sides of the four inserting grooves 11. Two knocking members 2 provided in insertion grooves 11 provided at both ends of the housing 1 can be used for exercising the thumb and the little finger, and the other five insertion grooves 11 can be selectively used for exercising the index finger, the middle finger and the ring finger, and the knocking members 2 are arranged so that the fingering and the finger force of the fingers can be well exercised.
