The utility model discloses a thyroid function measuring and counting device which comprises a measuring instrument and a counter which are movably connected with each other, a lifting handle is fixedly connected to the center of the top of the measuring instrument, a display screen is arranged on the left portion of the front face of the measuring instrument, and a connecting block is arranged on the right portion of the surface of the measuring instrument. A butt joint block is fixedly connected to the upper portion of the back face of the connecting block, and a butt joint inserting groove is formed in the surface of the connecting block. According to the utility model, the butt joint block is arranged on the back surface of the counter, the butt joint block is inserted into the butt joint slot on the surface of the connecting block, and then the positioning insertion rod is inserted into the positioning hole, so that the counter is further fixed, the stability of the counter after being installed is ensured, and during the installation operation, the limiting stop block is blocked outside the storage groove, so that the counter is prevented from being damaged. And the first telescopic rod cannot move backwards, so that when people insert the counter, the connecting block cannot move backwards, and the installation work of people is further facilitated.

The utility model provides a precise steel ball screening and counting device, and belongs to the technical field of steel ball machining. The precise steel ball screening and counting device comprises a screening and counting machine and a counting dust blocking mechanism, a discharging hopper is installed on the left side of the screening and counting machine, a visual counting sensor is installed on the top of the discharging hopper, a controller is installed on the front side of the screening and counting machine, and a dust blocking box is movably connected to the top in the discharging hopper. By arranging the counting and dust blocking mechanism, counting and dust blocking work can be conducted on the visual counting sensor, and it is avoided that external impurities are directly attached to the surface of the visual counting sensor during work of the visual counting sensor, and consequently follow-up impurity cleaning of the visual counting sensor is caused; therefore, the counting and dust blocking effects of the visual counting sensor are improved, and the service life of the visual counting sensor is prolonged.

A life-end locking mechanism for an inhaler is provided, the inhaler being of the type including a mechanical button (107) operable by a user to dispense a dose from the inhaler. The life-end locking mechanism includes: locking activation elements (106, 109) configured to be located within an outer housing (101a, 101b) of the inhaler, the locking activation elements (106, 109) configured such that operation of the inhaler causes the locking activation elements (106, 109) to move within the housing (101a, 101b); and a blocking element (110) configured to... Located within the housing (101a, 101b) of the inhaler, the blocking element (110) is configured such that the blocking element (110) can move from a first position or a first set of positions during normal operation of the inhaler to a second position that blocks the user from operating the button (107), wherein operation of the inhaler causes the locking activation element (106, 109) to move stepwise within the housing (101a, 101b) with each use of the inhaler until the locking activation element (106, 109) reaches a preset point and causes the blocking element (110) to move to the second position.
