Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3This utility model provides a technical solution: an auxiliary mechanism for an index measuring instrument, including an instrument body 1 and a housing 2. The housing 2 is provided with a control panel 5, a mounting part 3, and a locking part 4. The mounting part 3 has a cavity 6 inside. The control panel 5 is provided with a concave plate 7 for covering the control panel 5. A connecting block 8 is fixed to the end face of the concave plate 7 near the mounting part 3. A coil spring 9 is provided inside the housing 2. The output end of the coil spring 9 is fixed to the connecting block 8. The locking part 4 includes a positioning block 41 and a limiting rod 42 for locking the concave plate 7. By providing the mounting part 3, the locking part 4, and the concave plate 7, it is convenient to maintain and keep the control panel 5 of the instrument clean when it is not in use.

[0022] An insertion rod 11 is provided on the end face of the concave plate 7 near the locking part 4. A positioning groove 12 is provided on the insertion rod 11. A protruding strip 13 is provided on the concave plate 7. A soft brush 10 is fixed on the bottom surface of the concave plate 7. An opening is provided on the mounting part 3 to facilitate the entry and exit of the concave plate 7. By providing the soft brush 10, it is convenient to remove dust when the concave plate 7 moves.

[0023] The positioning block 41 is fixed to the measuring instrument body 1. The positioning block 41 has a movable groove 43 that matches the limiting rod 42. The limiting rod 42 is provided with an annular block 44 and a spring 45. The end of the spring 45 away from the annular block 44 is fixed to the inner wall of the movable groove 43. By setting the insertion rod 11, the annular block 44 and the spring 45, it is convenient to control the locking and limiting of the concave plate 7.

[0024] The limiting rod 42 is provided with a lever 46. The bottom end of the limiting rod 42 is inserted into the positioning groove 12. The positioning block 41 is provided with a plug groove 47 that matches the insertion rod 11. The plug groove 47 communicates with the movable groove 43. By providing the lever 46, it is convenient for personnel to control the locking and unlocking of the limiting rod 42 on the concave plate 7. Thus, the auxiliary mechanism of the index measuring instrument can effectively maintain the clean environment of the control panel and improve the measuring efficiency.

[0025] Working principle: When the measuring personnel need to use the instrument, they pull the lever 46 upwards, which drives the limit rod 42 to move upwards. The limit rod 42 releases the lock on the concave plate 7. The coil spring 9 is connected to the concave plate 7 through the connecting block 8, so that the concave plate 7 always has the tendency to move and be stored in the mounting part 3. After the lock is released, the concave plate 7 is basically retracted into the cavity 6, so that the control panel 5 is exposed in front of the measuring personnel for easy operation.

[0026] After the measurement is completed, the operator pushes the raised strip 13, which moves the concave plate 7 toward the locking part 4 until the insertion rod 11 is inserted into the insertion slot 47. During insertion, the end of the insertion rod 11 pushes open the limiting rod 42. Then the spring 45 extends, which drives the annular plate 44 to descend, so that the bottom end of the limiting rod 42 is inserted into the positioning slot 12, locking the insertion rod 11 and the concave plate 7. At the same time, during the movement of the concave plate 7, the soft brush 10 contacts the surface of the control panel 5 (display screen and button part), which can remove some dust. The concave plate 7 covers the control panel 5 to prevent dust. Thus, the auxiliary mechanism of this index measuring instrument can effectively maintain the clean environment of the control panel and improve the measurement efficiency.

[0027] The mechanisms, components, and parts in this utility model that are not specifically described are all existing structures that already exist in the prior art and can be purchased directly from the market.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
