Description

Technical Field

[0001] The utility model relates to the technical field of instruments, and in particular to an instrument positioning and installation device. Background Art

[0002] Digital display instruments are becoming more and more common in today's social life and industrial production, which makes the installation and positioning of instruments more and more important. In order to facilitate observation, there are new requirements for the direction of instrument assembly. On traditional equipment, two parallel positioning surfaces are usually set in the circumferential direction of the hole seat to determine the angular position of the instrument in the circumferential direction. Two parallel positioning surfaces are also set in the circumferential direction of the instrument. The directional positioning of the instrument can be achieved by assembling and cooperating the instrument with the positioning surface of the hole seat.

[0003] However, this traditional positioning method has some problems in actual operation. First, in the early stage of positioning, the instrument needs to be supported, which makes the positioning process very difficult. Secondly, the improper size matching between the instrument and the hole seat may cause a small skew in the direction positioning. If the gap is too large, it will lead to inaccurate positioning; if the gap is too small, it will bring too high requirements to production and manufacturing, and may cause assembly jams.

[0004] In addition, the connection between the meter and the hole seat is usually achieved by threading the pressure ring and the hole seat and tightening it by spinning, or by tightening it with screws. These methods require the use of special tools, which is time-consuming and inconvenient. Therefore, the traditional positioning and installation methods of circular meters can no longer meet the needs of regular batch maintenance.

[0043] 3. Telescopic positioning components,

[0044] Figure 5 Schematic diagram of the structure of the telescopic positioning assembly provided by the embodiment of the utility model; Figure 5 As shown, the telescopic positioning assembly is used to penetrate into the blind hole; when the base 6 is rotated until the blind hole is aligned with the slot 5, the telescopic positioning assembly extends from the blind hole and is clamped in the slot 5 to position the base 6 and the mounting slot 1.

[0045] The telescopic positioning assembly includes a spring 11 and a latch 12;

[0046] The spring 11 is installed in the first blind hole 9; the latch 12 is used to penetrate into the first blind hole 9 to squeeze the spring 11 in the first blind hole 9; when the base 6 is rotated until the first blind hole 9 is aligned with the slot 5, the latch 12 extends from the first blind hole 9 and is locked in the slot 5 to position the base 6 and the installation slot 1.

[0047] The telescopic positioning assembly further includes: a trigger 13;

[0048] The trigger 13 is used to pass through the second blind hole 10 and be fixedly connected with the threaded hole in the middle of the latch 12; when the trigger 13 drives the latch 12 to move toward the spring 11, the trigger 13 is tilted and laid down and stuck by the second blind hole 10, thereby limiting the position of the latch 12.

[0049] Specifically, the spring 11 is installed at the innermost part of the first blind hole 9, and the latch 12 penetrates into the circular blind hole from the outside to squeeze the spring 11 into the circular blind hole; the trigger 13 is inserted into the threaded hole of the latch 12 at the L-shaped blind hole to be fixedly connected with the thread.

[0050] When the spring 11 is in a normal telescopic state, the head end of the latch 12 will extend out of the circular blind hole of the base 6; the trigger 13 is on the short side of the L-shaped blind hole; in the daily turnover storage state, the trigger 13 is pulled (moved) along the L-shaped blind hole toward the spring 11; the movement of the trigger 13 drives the latch 12 to move, thereby compressing the spring 11, so that the spring 11 is in a compressed state, and when it moves to the intersection of the long side and the short side of the L-shaped blind hole, the trigger 13 is tilted and laid down in the long side of the L-shaped blind hole, so that the trigger 13 is stuck on the left and right sides of the long side of the L-shaped blind hole. At this time, the trigger 13 limits the latch 12, and the head end of the latch 12 is completely in the circular blind hole, and the spring 11 is in a compressed state;

[0051] When the base 6 to which the instrument dial 7 is fixedly connected needs to be assembled into the groove 3 of the hole seat 2, the trigger 13 needs to be pulled back from the long side of the L-shaped blind hole to the short side of the L-shaped blind hole. The movement of the trigger 13 drives the bolt 12 to move. At this time, the head end of the bolt 12 extends out of the circular blind hole, and the spring 11 is in a normal telescopic state; the two ears 8 of the base 6 are screwed into the semicircular notch 4 of the groove 3. At this time, the head end of the bolt 12 is squeezed by the groove 3, and the head end of the bolt 12 is retracted into the circular blind hole, the spring 11 is compressed, and then the base 6 is rotated. When the bolt 12 is rotated to the position of the slot 5, the external force squeezing is lost, the spring 11 is released, the bolt 12 extends out of the base 6 and is stuck in the slot 5, the base 6 cannot continue to rotate, and circumferential positioning is achieved.

[0052] Finally, a butterfly screw is screwed into at least two through threaded holes arranged on the outer surface of the groove 3 so that the end of the butterfly screw is against the outer surface of the base 6 to achieve axial limiting.

[0053] The structure of the utility model can realize the positioning and installation of the instrument without any tools during the application process, making the operation more convenient and efficient; and ensuring the accurate positioning and installation of the instrument.
