Abstract
Description
Technical Field
[0001] This utility model relates to the field of photoelectric probe technology, specifically to a corrosion-resistant photoelectric probe. Background Technology
[0002] A photoelectric probe is a device that can sense light signals and convert them into electrical signals or other easily processed signals. Due to its advantages such as high precision, non-contact measurement, and fast response, photoelectric probes are widely used in many fields such as industrial automation, medical testing, environmental monitoring, security monitoring, and scientific research experiments.
[0003] Existing photoelectric probes are usually directly exposed to the outside. In environments with corrosive gases, liquids, or dust, such as chemical, marine, and food processing industries, exposed photoelectric probes are highly susceptible to corrosion, leading to performance degradation or even failure. For example, a photoelectric sensor probe assembly disclosed in patent CN218496125U has no protective structure for the probe body. However, without a protective structure, the probe body is highly susceptible to the influence of the external environment. It is not only easily damaged by accidental impacts or scratches, but also easily corroded by the external environment. The loss of measurement accuracy and stability may lead to inaccurate data. Therefore, this design may not meet the requirements in applications that require special protection or adaptation to complex environments.
[0004] Therefore, it is necessary to invent a corrosion-resistant photoelectric probe to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a corrosion-resistant photoelectric probe to solve the problem that photoelectric probes in the present invention do not have a protective structure and are not only easily damaged by accidental impacts or scratches, but are also easily corroded by the external environment.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a corrosion-resistant photoelectric probe, comprising a detector, a photoelectric probe body, and a protective cover. A mounting base is provided above the detector, and the photoelectric probe body is positioned at the center of the mounting base. A protective cover is provided on the outer side of the photoelectric probe body, and a mounting plate is provided below the protective cover. Sliding rods are arranged around the top of the mounting base, and a fixed chuck and a sliding chuck are provided on the sliding rods. A sleeve is provided on the side wall of the mounting plate, and a groove is provided inside the sleeve. A connecting rod is provided inside the groove, and a locking block is provided at one end of the connecting rod.
[0007] Preferably, the mounting plate is located above the mounting base, and the mounting plate and the mounting base are detachably connected, so that the protective cover and its mounting plate can be easily installed and removed.
[0008] Preferably, the protective cover has a semi-circular hollow structure design and is made of polytetrafluoroethylene (PTFE). The inner diameter of the protective cover is larger than the outer diameter of the photoelectric probe body. PTFE has excellent corrosion resistance and can resist the erosion of various corrosive media, thereby protecting the photoelectric probe body from corrosion and extending its service life.
[0009] Preferably, the fixed chuck has an inverted triangular structure and the sliding chuck has an equilateral triangular structure. The combination of the inverted triangle and the equilateral triangle allows the mounting plate to be automatically aligned and securely fixed between the fixed chuck and the sliding chuck when it is inserted.
[0010] Preferably, the fixed chuck is located directly above the sliding chuck, the fixed chuck is fixedly connected to the slide rod, and the sliding chuck is slidably connected to the slide rod, so that the sliding chuck can slide up and down on the slide rod.
[0011] Preferably, the fixed chuck and the sliding chuck are provided with mounting slots at the positions corresponding to the mounting plate. There are four mounting slots, which cooperate with the fixed chuck and the sliding chuck. The mounting slots enable the mounting plate to be accurately aligned and snapped between the fixed chuck and the sliding chuck, thereby achieving a stable installation of the protective cover.
[0012] Preferably, one end of the connecting rod extends through the sleeve to its outside, the connecting rod and the sleeve are slidably connected, a spring is sleeved on the connecting rod and located inside the groove, when the groove on the mounting plate is engaged between the fixed chuck and the sliding chuck, the locking block can automatically extend and retract under the action of the spring.
[0013] Preferably, the locking block is located on the left and right sides of the fixed chuck and the sliding chuck. The locking block has a right-angled trapezoidal structure design. The inclined side of the locking block can guide it to be smoothly locked into the mounting groove. After being locked in, the right-angled side fits tightly into the mounting groove to achieve a stable locking connection.
[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0015] 1. This utility model adopts a semi-circular hollow structure design to tightly wrap the photoelectric probe body with a protective cover, and the protective cover is made of polytetrafluoroethylene material. This material has excellent corrosion resistance and can resist the erosion of a variety of corrosive media. This not only provides physical protection, but also further enhances the anti-corrosion effect through its material, thereby effectively protecting the photoelectric probe body from corrosion and extending its service life.
[0016] 2. The protective cover of this utility model is fixed through a detachable connection between the mounting plate and the mounting base. During installation, the mounting groove smoothly fits into the fixed chuck, and the inclined edge of the locking block can tightly fit against the bottom surface of the fixed chuck, achieving a stable engagement. During disassembly, by pressing the mounting plate, the locking block continues to move downward until it is located below the sliding chuck. At this time, the locking block lifts the sliding chuck and moves it upward, achieving precise engagement between the sliding chuck and the fixed chuck. At the same time, the locking block can automatically extend and retract under the action of the spring, thereby achieving disassembly. This disassembly and assembly method is simple and quick, without the need for bolts or other fasteners, thus achieving the purpose of rapid installation and disassembly. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0026] This utility model provides, for example Figure 1-6The image shows a corrosion-resistant photoelectric probe, comprising a detector 1, a photoelectric probe body 3, and a protective cover 5. A mounting base 2 is positioned above the detector 1, and the photoelectric probe body 3 is positioned at the center of the mounting base 2. The protective cover 5 is positioned on the outer side of the photoelectric probe body 3, and a mounting plate 4 is positioned below the protective cover 5. The mounting plate 4 is located above the mounting base 2 and is detachably connected to the mounting base 2. The protective cover 5 has a semi-circular hollow structure and is made of polytetrafluoroethylene (PTFE). The inner diameter of the protective cover 5 is larger than the outer diameter of the photoelectric probe body 3. Slide rods 6 are arranged around the top of the mounting base 2, and fixed chucks 7 and sliding chucks 8 are mounted on the slide rods 6. A sleeve 10 is provided on the side wall of the mounting plate 4, and a groove 11 is provided inside the sleeve 10. A connecting rod 12 is provided inside the groove 11, and a locking block 14 is provided at one end of the connecting rod 12.
[0027] The protective cover 5 protects the photoelectric probe body 3 from external environmental corrosion, such as corrosive gases, liquids, or dust. The use of polytetrafluoroethylene material gives the protective cover 5 excellent corrosion resistance, which can extend the service life of the photoelectric probe body 3.
[0028] The fixed chuck 7 has an inverted triangular structure, and the sliding chuck 8 has an equilateral triangular structure. The fixed chuck 7 is located directly above the sliding chuck 8. The fixed chuck 7 is fixedly connected to the slide rod 6, and the sliding chuck 8 is slidably connected to the slide rod 6. The fixed chuck 7 and the sliding chuck 8 are provided with mounting grooves 9 at the positions corresponding to the mounting plate 4. There are four mounting grooves 9, which cooperate with the fixed chuck 7 and the sliding chuck 8. One end of the connecting rod 12 extends through the sleeve 10 to its outside. The connecting rod 12 is slidably connected to the sleeve 10. A spring 13 is sleeved on the connecting rod 12 and located inside the groove 11. The locking block 14 is located on the left and right sides of the fixed chuck 7 and the sliding chuck 8. The locking block 14 has a right-angled trapezoidal structure.
[0029] The design of the fixed chuck 7 and sliding chuck 8, which are inverted and equilateral triangles, and the cooperation between the locking block 14 and the fixed chuck 7 and sliding chuck 8, enable the mounting plate 4 to be accurately aligned and installed on the mounting base 2, achieving a stable locking connection. The sliding connection between the sliding chuck 8 and the slide rod 6 allows the sliding chuck 8 to slide up and down on the slide rod 6, thereby adjusting the distance between it and the fixed chuck 7, facilitating installation and disassembly. Furthermore, the locking block 14 can automatically extend and retract under the action of the spring 13, making the disassembly process simpler and faster.
[0030] Working principle of this utility model:
[0031] Refer to the instruction manual appendix Figure 1-5When using this utility model, first align the protective cover 5 with the center position above the mounting base 2 via the mounting plate 4 below it, that is, the outer side of the photoelectric probe body 3. Gently press the mounting plate 4 so that the mounting groove 9 on the mounting plate 4 can be smoothly fitted onto the fixed chuck 7. At this time, the oblique side of the locking block 14 in the sleeve 10 on the side wall of the mounting plate 4 is aligned with the bottom surface of the fixed chuck 7. At this time, the locking block 14 will partially retract under the action of the spring 13, ensuring that the extended end of the locking block 14 can be tightly fitted to the bottom surface of the fixed chuck 7 to achieve the locking.
[0032] Refer to the instruction manual appendix Figure 6 When using this utility model, if disassembly is required, simply continue pressing the mounting plate 4. During the pressing process, the mounting groove 9 and the locking block 14 continue to move downwards. At this time, the locking block 14 disengages from the fixed chuck 7 during the pressing process and automatically extends and retracts under the action of the connecting rod 12 and the spring 13, locking it below the sliding chuck 8. Then, by lifting the mounting plate 4, the locking block 14 drives the sliding chuck 8 to engage with the fixed chuck 7. When the sliding chuck 8 moves to a certain position, the locking block 14 will extend and retract again under the action of the spring 13, allowing the locking block 14 to disengage from the engagement state between the sliding chuck 8 and the fixed chuck 7. Finally, gently remove the mounting plate 4 together with the protective cover 5 from the mounting base 2 to complete the disassembly operation.
