Description

Technical Field

[0001] The utility model belongs to the technical field of counters, and more specifically, particularly relates to a photoelectric instrument mechanical counter. Background Art

[0002] Counting is the simplest and most basic operation. A counter is a logic circuit that implements this operation. In a digital system, a counter mainly counts the number of pulses to achieve measurement, counting and control functions, and also has a frequency division function. A counter is composed of a basic counting unit and some control gates. The counting unit is composed of a series of various triggers with information storage functions, such as RS triggers, T triggers, D triggers and JK triggers.

[0003] Based on the above, the inventors have found the following problems: when the existing photoelectric counters are used in some places with sufficient light, strong light may affect the photoelectric switch, resulting in inaccurate counting. At the same time, after use, most of them are placed directly, and the surface of the photoelectric switch is directly exposed to the air, which will cause dust or impurities in the air to be adsorbed on its surface, causing inconvenience to the staff's subsequent use and indirectly reducing the efficiency of use.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a photoelectric instrument mechanical counter is provided to achieve a purpose with greater practical value. Utility Model Content

[0005] The purpose and effect of the photoelectric instrument mechanical counter of the utility model are achieved by the following specific technical means:

[0006] A photoelectric instrument mechanical counter comprises a shell, a rotating shaft is installed at the top of the shell, a counter is connected to the top of the rotating shaft, a chamber is opened inside the shell, a first protective mechanism is installed inside the chamber, a photoelectric switch is arranged on the surface of the shell, and a second protective mechanism is installed at one end of the photoelectric switch.

[0007] Furthermore, the first protection mechanism includes a group of electric telescopic rods, and a protection plate is fixedly mounted on one end of the electric telescopic rods.

[0008] Furthermore, a driving motor 1 is disposed inside the shell, and an output end of the driving motor 1 passes through the shell to the outside to form a transmission connection with the rotating shaft.

[0009] Furthermore, the second protection mechanism includes a set of mounting frames, a worm is mounted on one end of the mounting frame, a bearing is mounted below the worm, and an arc-shaped protection plate is mounted on the bearing.

[0010] Furthermore, a worm gear is provided at the top end of the arc-shaped protective plate, and the worm gear is meshed with the worm.

[0011] Furthermore, one end of the mounting frame is connected to drive motor 2, and the output end of drive motor 2 passes through the mounting frame to the inside to form a transmission connection with the worm.

[0012] Furthermore, a counting display screen is provided on the surface of the counter.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] Through the cooperation between the electric telescopic rod and the protective plate, when the staff uses the counter under some strong light, they can open the electric telescopic rod to extend the protective plate to protect the photoelectric switch from light, avoiding inaccurate counting under strong light, indirectly improving the use efficiency, and it is very convenient.

[0015] Through the cooperation between the driving motor 1 and the rotating shaft, the staff can start the driving motor 1 according to their own position to rotate the counter to a suitable observation position, which is convenient for the staff to observe it in real time and indirectly improves the observation efficiency.

[0016] Through the cooperation between the worm and the worm wheel, before using the counter, the staff can start the second driving motor to drive the worm to rotate, and then the worm will drive the worm wheel to rotate, so that the photoelectric switch can be exposed and used normally. After use, start the second driving motor again to make the worm wheel cover the photoelectric switch, which effectively prevents impurities or dust in the air from being adsorbed on the surface of the photoelectric switch when it is placed for a long time, indirectly improving the protection efficiency. This design brings convenience to the subsequent use of the staff and greatly increases the practicality. BRIEF DESCRIPTION OF THE DRAWINGS
