Two cross rods 3 are horizontally and transversely arranged in the box body 1, the left end of each cross rod 3 is fixedly connected with the inner wall of the left side of the box body 1, and the right end of each cross rod is fixedly connected with the inner wall of the right side of the box body 1.

Referring to fig. 3 and 4, fig. 3 is a right side sectional view of fig. 1 according to an embodiment of the present invention, and fig. 4 is a left side sectional view of fig. 1 according to an embodiment of the present invention.

A rotating shaft 4 which is horizontal and perpendicular to the two cross rods 3 is rotatably connected between the two cross rods 3. A driving motor 13 for driving the rotating shaft 4 to rotate is fixedly mounted on the inner wall of the box body 1, the driving motor 13 is a forward and reverse rotating motor, and one end, far away from the driving motor 13, of the rotating shaft 4 is rotatably connected with the inner wall of one side, far away from the driving motor 13, of the box body 1 through a bearing 14. The driving motor 13 is fixedly mounted on the inner wall of the rear side of the box body 1, and an output shaft of the driving motor 13 is coaxially and fixedly connected with one end of the rotating shaft 4. The bearing 14 is fixedly arranged on the inner wall of the front side of the box body 1, and the other end of the rotating shaft 4 is fixedly inserted into an inner ring of the bearing 14.

In this embodiment, as shown in fig. 2, a gear 5 is fixedly sleeved on the rotating shaft 4, two vertical rods 6 respectively arranged on two sides of the gear 5 penetrate through the two cross rods 3 in a vertical sliding manner, and racks 7 engaged with the gear 5 are respectively embedded on opposite sides of the two vertical rods 6. Correspond every montant 6 on two horizontal poles 3 and be provided with the sliding hole that runs through of adaptation respectively, montant 6 passes the sliding hole that runs through that corresponds and slides from top to bottom, and rack 7 is fixed to be inlayed and is established on montant 6, can not lead to the fact the hindrance when sliding from top to bottom to montant 6.

With continued reference to fig. 2, in the present embodiment, the upper end of one of the vertical rods 6 is fixedly connected with a hitting cone 8 extending upward from the upper end of the box body 1, a copper plate 9 is arranged outside the upper end of the box body 1 corresponding to the hitting cone 8, and the copper plate 9 is fixed outside the upper end of the box body 1 through a copper plate bracket 12. The copper support 12 is vertical, and 9 levels of copper set up and just in time be located and hit 8 tops of awl, and 9 one end of copper links firmly with 12 upper ends of copper support.

The upper end of box 1 corresponds hits the awl of hitting that hits awl 8 and set up the adaptation and wears out the hole, hits the vertical setting of awl 8 and wears out the hole through hitting the awl and pass the upper end of box 1, hits the diameter that hits awl 8 and is less than the diameter of montant 6 to the cover is equipped with first spring 15 beating awl 8, and 15 one ends of first spring are supported and are pressed on the inner wall of box 1 upper end, and the 15 other end of first spring supports and press the upper end of hitting montant 6 that awl 8 links to each other. In addition, a first buffer rubber block 16 is arranged on the inner wall of the lower end of the box body 1 and corresponds to the lower end of the vertical rod 6 connected with the beating cone 8.

With continued reference to fig. 2, in the present embodiment, the lower end of the other vertical rod 6 is fixedly connected with a connecting rod 10 extending downward from the lower end of the box body 1, and the lower end of the connecting rod 10 is fixedly connected with a stop plate 11. The stop plate 11 is wrapped with a friction-resistant rubber layer.

The connecting rod that the adaptation was seted up to box 1 lower extreme corresponds connecting rod 10 pierces the hole, and connecting rod 10 is vertical to be set up and to pass box 1 lower extreme through the connecting rod pierces the hole. The diameter of connecting rod 10 is less than the diameter of montant 6 to the cover is equipped with second spring 17 on connecting rod 10, and second spring 17 one end is supported and is pressed on box 1 lower extreme inner wall, and the second spring 17 other end supports and presses the lower extreme at montant 6 that links to each other with connecting rod 10. A second buffer rubber block 18 is arranged on the inner wall of the upper end of the box body 1 corresponding to the upper end of the vertical rod 6 connected with the connecting rod 10.

When the box body 1 is used, a user starts and controls the driving motor 13 to rotate in the forward direction through the external controller, the driving motor 13 drives the rotating shaft 4 to rotate in the forward direction, the rotating shaft 4 rotates in the forward direction to drive the gear 5 to rotate in the forward direction, the gear 5 is respectively meshed with the racks 7 embedded on the two vertical rods 6, therefore, the vertical rods 6 connected with the striking cones 8 drive the striking cones 8 to move upwards and finally strike the copper plates 9 to generate crisp sounds, meanwhile, the vertical rods 6 connected with the connecting rods 10 drive the connecting rods 10 to move downwards, the stop plates 11 connected with the connecting rods 10 move downwards together, and finally the stop plates 11 can be pressed on the ground while the striking cones 8 strike the copper plates 9, so that the box body 1 is stopped at a certain position, and when the striking cones 8 and the connecting rods 10 move, the first springs 15 and the second springs 17 respectively generate elastic potential energy to play a role of elastic buffering, the cushioning effect of the second springs 17 helps to reduce the noise generated by the contact of the stop plate 11 with the ground, and the sound-absorbing material layer on the inner wall of the case 1 helps to reduce the noise generated by the driving motor 13 and other structures inside the case 1. The user passes through the reversal of peripheral hardware controller control driving motor 13, and two montants 6 can reset respectively and make box 1 remove again, for preventing that two montants 6 from taking place hard contact with the box 1 inner wall when reseing, first buffering is glued piece 16 and second buffering and is glued piece 18 and play protection box 1 and play the effect of the buffering that resets to two montants 6, avoids montants 6 and box 1 hard contact to bring the damage.

From the above description, it is difficult to see that this application has solved current hearing test equipment and has mostly been manual operation when using, wastes time and energy, and easily influences last test result, leads to current hearing test equipment problem that work efficiency is low when using, has made things convenient for user's use, has improved hearing test equipment's practicality.

The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
