DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0022] like Figures 1 to 6 As shown, an automatic control instrument comprises an instrument body 1, which is an automatic control instrument. A display screen 2 and a plurality of buttons 3 are arranged on the instrument body 1. Various electrical components required for automatic control are arranged on the instrument body 1. Two guide plates 4 are fixedly installed on one side of the instrument body 1. A limited slide groove 5 is provided on one side of the two guide plates 4. Two slide plates 6 are slidably connected to the inner walls of the two limited slide grooves 5. A mounting plate 7 is fixedly connected on one side of the four slide plates 6. A baffle 8 is fixedly connected on one side of the two mounting plates 7. A handle 9 is fixedly connected on one side of the baffle 8. The baffle 8 is convenient to move by the handle 9. Under normal conditions, the two baffles 8 are fitted together. The buttons 3 are fully protected by the two baffles 8. The top sides of the two mounting plates 7 located above are fixedly connected with racks 10. The two symmetrical sides of the instrument body 1 are fixed A support block 11 is connected, and one side of the support block 11 is rotatably connected to a rotating shaft 12 through a bearing. One end of the rotating shaft 12 is fixedly connected to a gear 13 meshing with the rack 10, and one side of the gear 13 is fixedly connected to a torsion spring 14. When the button 3 needs to be used, the baffle 8 is moved by the handle 9 so that the baffle 8 no longer blocks the button 3. In this process, the mounting plate 7 drives the slide plate 6 to move. As the mounting plate 7 moves, the rack 10 moves accordingly. Under the meshing transmission action of the rack 10 and the gear 13, the rotating shaft 12 rotates. At this time, the torsion spring 14 will be deformed, so that the baffle 8 no longer blocks the button 3, and the button 3 can be used. After the button 3 is used, the handle 9 is slowly released, and the gear 13 is reversely rotated under the reaction force of the torsion spring 14. At this time, the rack 10 will drive the mounting plate 7 and the baffle 8 to reset, so that the baffle 8 performs a shielding and protective operation on the button 3 again.

[0023] As an optional technical solution of the present invention, a transparent observation window 15 is provided on one side of the baffle 8, through which the status of the button 3 can be observed, so that the baffle 8 corresponding to the button 3 can be moved according to the button 3 used.

[0024] As an optional technical solution of the utility model, the limiting slide groove 5 and the slide plate 6 are both T-shaped, and the slide plate 6 is adapted to the size of the limiting slide groove 5 to ensure that the slide plate 6 does not separate from the limiting slide groove 5 while moving.

[0025] As an optional technical solution of the present invention, the baffle 8 corresponds to the position of the button 3, there are two baffles 8, and the sum of the sizes of the two baffles 8 is larger than the area where several buttons 3 are located, so that the baffle 8 can perform comprehensive protection operations on the button 3.

[0026] As an optional technical solution of the present invention, one end of the torsion spring 14 away from the gear 13 is fixedly connected to the support block 11, and a part of the rotating shaft 12 is located inside the torsion spring 14, so that the torsion spring 14 can be deformed as the gear 13 rotates.

[0027] As an optional technical solution of the present invention, the baffle plate 8 is fitted with one side of the guide plate 4, and the baffle plate 8 is slidably connected to the guide plate 4, so that the baffle plate 8 can move smoothly.

[0028] An automatic control instrument, the working principle is as follows:

[0029] When the button 3 needs to be used, the baffle 8 is moved by the handle 9 so that the baffle 8 no longer blocks the button 3. In this process, the mounting plate 7 drives the slide plate 6 to move. As the mounting plate 7 moves, the rack 10 moves accordingly. Under the meshing transmission action of the rack 10 and the gear 13, the rotating shaft 12 rotates. At this time, the torsion spring 14 will be deformed so that the baffle 8 no longer blocks the button 3. At this time, the button 3 can be used. After the use of the button 3 is completed, the handle 9 is slowly released, and the gear 13 is rotated in the opposite direction under the reaction force of the torsion spring 14. At this time, the rack 10 will drive the mounting plate 7 and the baffle 8 to reset, so that the baffle 8 can again block and protect the button 3.

[0030] To sum up, the automatic control instrument, through the coordinated arrangement of the guide plate 4, the limiting slide groove 5, the slide plate 6, the mounting plate 7, the baffle 8, the handle 9, the rack 10, the support block 11, the rotating shaft 12, the gear 13 and the torsion spring 14, adds a structure for protecting the button 3 on the basis of the existing automatic control instrument, thereby avoiding the situation where the operator accidentally touches the button 3, ensuring the normal working process of the automatic control instrument, and making the operation of moving the baffle 8 relatively simple. After the use of the button 3 is completed, the baffle 8 can be automatically reset and the button 3 can be shielded and protected.
