The applicant researches and discovers that:

In view of this, referring to fig. 1 to 7, in the present disclosure, there is provided a xylophone key structure including a base 10, a wood block 20 and a panel 30;

the panel 30 includes a pressing portion 31 and a clamping portion 32, and the clamping portion 32 is disposed at one end of the pressing portion 31;

the base 10 is provided with a connecting seat 11 matched and fixed with the clamping part 32;

the wood block 20 is arranged between the pressing part 31 and the panel 30;

the clamping portion 32 comprises an elastic member 33 and a limiting member 34, the connecting seat 11 comprises a clamping groove 12 and a limiting groove 13, the elastic member 33 is clamped in the clamping groove 12, and the limiting member 34 is in limiting connection with the limiting groove 13.

It should be noted that, during assembly, the wood block 20 and the pressing portion 31 of the panel 30 are fixed together, the fastening portion 32 extends out of the connecting portion, the fastening portion 32 is fixed with the connecting seat 11, and then the panel 30 and the wood block 20 are pressed on the base 10, wherein the wood block 20 is respectively bonded and connected with the base 10 and the panel 30, so as to realize the fixed connection between the three, more specifically, when the fastening portion 32 is connected with the connecting seat 11, the positioning between the limiting member 34 and the limiting groove 13 is utilized to realize the positioning between the panel 30 and the base 10 in the left-right and front-back directions, without using the wood block 20 to perform the positioning in the left-right and front-back directions, and the fastening relationship between the elastic member 33 and the fastening groove 12 is utilized to realize the connection between the panel 30 and the base 10, the positioning during assembly is more convenient and stable, and the problem that the accuracy of the processing size of the wood block 20 is not high is avoided, and is susceptible to environmental climate, resulting in uncontrollable size changes, and objectively existing influencing factors are as follows: water-absorbing expansion, or shrinkage deformation, and bending or distortion deformation occurring after a period of time of standing, eventually causing a problem of large assembly deviation; the key equipment uniformity is better, and the assembly is simpler reliable, and follow-up use is difficult for taking place the deformation problem yet.

Referring to fig. 4 and 5, as an embodiment, the longitudinal section of the limiting groove 13 is V-shaped, and has a shape with a large top and a small bottom, which is more beneficial for placing the limiting member 34 in the limiting groove 13.
