Mouse metabolism cage with adjustable internal space

Abstract

The invention relates to the field of experimental instruments, and provides an internal space adjustable mouse metabolism cage which comprises supports, a base is fixed to the top end of each support, and an adjusting structure is mounted at the top end of each base. And the adjusting structure comprises a second mounting block, a first connecting rod, a first rack, a first gear, a second connecting rod, a first external pipe, a first internal pipe, a third connecting rod, a second external pipe, a second internal pipe, a first limiting block, a second rack, a second limiting block and a second gear. By arranging an adjusting structure, a handle drives a connecting shaft, the connecting shaft drives a first gear and a second gear to rotate, the first gear drives a first rack to move in the opposite direction, the first rack drives a second connecting rod to move, and a second built-in pipe slides in a first limiting block; and thus, a first built-in pipe is driven to slide in a first external pipe, the function of adjusting the internal space of the device is achieved, and the convenience of the mouse metabolism cage is improved.
