$obj=& get_instance();
$obj->load->module('login_check');
$var=$obj->login_check->get_all_table_data();

Code:

class Mylib {
    private $CI;

function __construct() {
        $this->CI =& get_instance();
}

function show_lib()
{
    $this->CI->load->model('login_check');
}



}

model/module depending on what you want to do (module if you using HMVC and you want full module loaded in, then use it like $this->CI->login_check->fnc();
