Description

Technical Field

[0001] The utility model belongs to the technical field of pulse energy meters, and in particular relates to a pulse energy meter probe protection device. Background Art

[0002] A pulse energy meter is an instrument used to measure the energy of a laser or other pulsed light source. It typically consists of an energy sensor and a display. The energy sensor is a sensitive element that converts photon energy into an electrical signal. Its type and performance directly affect the accuracy and range of the measurement.

[0003] Commonly used pulse energy meter sensors include photodiode sensors, thermistor sensors, and pyroelectric sensors. However, these sensors are susceptible to surface damage and aging, which can affect their performance and lifespan. Especially during storage or transportation, sensors can be affected by mechanical shock, dust, moisture, dirt, impurities, and other environmental factors, which can reduce their reliability and stability.

[0004] To maintain the probe and extend its service life, a protective film is usually applied to or added to the probe surface to reduce the impact of environmental factors such as dust, moisture, dirt, and impurities. Although this method is simple and easy to implement, the protective film does not provide sufficient protection to reduce the impact of mechanical shock on the probe. Utility Model Content

[0019] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0020] like Figure 1-4 As shown, a pulse energy meter probe protection device includes a pulse energy meter body 1 and a probe body 2 thereon. The pulse energy meter body 1 and the probe body 2 are both existing mature technologies and will not be described in detail in this embodiment.

[0021] The pulse energy meter body 1 is also equipped with a protective assembly for protecting the probe body 2. The protective assembly includes a protective ring 3, and the diameter of the protective ring 3 is larger than the diameter of the probe body 2. The outer side of the protective ring 3 is provided with an external thread 4. The inner side of the pulse energy meter body 1 and the outer side of the probe body 2 are provided with a mounting groove adapted for the protective ring 3, and the inner side of the mounting groove is provided with an internal thread 5.

[0022] Refer to the attached Figure 1 and attached Figure 2 The guard ring 3 and the pulse energy meter body 1 are threadedly connected by an external thread 4 and an internal thread 5, so that the guard ring 3 and the pulse energy meter body 1 are detachably connected. Compared with other detachable connection methods, such as a bayonet pin connection and a magnetic connection, the threaded connection has some unique advantages, as follows:

[0023] Reliability and stability: Threaded connections rely on physical fastening and friction, making them more reliable and able to maintain their strength. In contrast, snap-on and magnetic connections are often more susceptible to vibration and external shock, potentially causing unstable, loose, or even failure.

[0024] Withstands harsh environments: Threaded connections are generally more resistant to high temperatures, high pressures, corrosive environments, and other harsh conditions. Snap-on and magnetic connections may have limited performance in these environments.

[0025] Refer to the attached Figure 2 and attached Figure 4 In addition, an annular sealing plate 13 is installed on the outer side of the end of the guard ring 3 close to the pulse energy meter body 1. When the guard ring 3 is threadedly connected to the pulse energy meter body 1, the annular sealing plate 13 contacts the pulse energy meter body 1 and deforms, thereby sealing the gap between the guard ring 3 and the pulse energy meter body 1;

[0026] Refer to the attached Figure 1 -Attached Figure 4 In addition, a protective cover 6 is provided at one end of the protective ring 3 away from the pulse energy meter body 1, and a first connecting plate 7 is fixed to one side of the protective ring 3, and a second connecting plate 8 adapted to the first connecting plate 7 is fixed to one side of the protective cover 6, and the second connecting plate 8 is rotatably connected to the first connecting plate 7 by a pin.

[0027] At the same time, a clamping plate 9 is installed at one end of the protective cover 6 close to the protective ring 3, and the clamping plate 9 is located on the side of the protective cover 6 away from the second connecting plate 8. A clamping groove adapted to the clamping plate 9 is opened inside the protective ring 3, so that the protective cover 6 and the protective ring 3 are clamped together by the arrangement of the clamping plate 9 and the clamping groove. In addition, a sealing ring 14 is installed at the end of the protective ring 3 close to the protective cover 6;

[0028] According to the above structure, when the protective assembly needs to be installed, it is easy to simply rotate the protective ring 3 so that it is threadedly connected to the pulse energy meter body 1. During this process, the annular sealing plate 13 contacts the pulse energy meter body 1 and deforms, effectively sealing the gap between the protective ring 3 and the pulse energy meter body 1.

[0029] When the probe body 2 needs to be used, it is only necessary to gently pull the protective cover 6, move the card plate 9 out of the inner side of the card slot, and rotate the protective cover 6 180 degrees with the pin as the center. Figure 3 As shown, the protective cover 6 is moved to the outside of the pulse energy meter body 1 and the protective ring 3 so as not to interfere with the normal operation of the probe body 2 .

[0030] When the pulse energy meter body 1 and probe body 2 are no longer needed, the protective cover 6 can simply be pushed back into place. The retaining plate 9 is now located inside the retaining groove, securing the protective cover 6 securely to the protective ring 3. During this process, the sealing ring 14 deforms under stress, sealing the gap between the protective ring 3 and the protective cover 6 and ensuring a tight seal.

[0031] In summary, when the probe body 2 is not in use, the structure of the protective ring 3 and the protective cover 6 can effectively prevent external objects from colliding with the probe body 2, thereby reducing the risk of damage to the probe body 2. In addition, the provision of the sealing ring 14 achieves a seal between the protective cover 6 and the protective ring 3, while the design of the annular sealing plate 13 ensures a seal between the pulse energy meter body 1 and the protective ring 3, thereby effectively preventing dust and impurities from adhering to the probe body 2 when the probe body 2 is not in use.

[0032] Refer to the attached Figure 2 and attached Figure 4 In addition, in order to strengthen the sealing between the pulse energy meter body 1 and the guard ring 3, a sealing ring 10 is fixed to one end of the annular sealing plate 13 close to the pulse energy meter body 1, and a sealing groove 11 adapted to the sealing ring 10 is opened inside the pulse energy meter body 1. When the guard ring 3 is threadedly connected to the pulse energy meter body 1, the sealing ring 10 is located inside the sealing groove 11 and deforms inside the sealing groove 11, thereby further improving the sealing between the pulse energy meter body 1 and the guard ring 3;

[0033] Refer to the attached Figure 2 and attached Figure 3 In addition, considering that the probe body 2 may be contaminated by dust, impurities, or even flies and insects during use, in order to reduce this possibility, a protective sheet 12 is also installed on the inner side of the protective ring 3. The protective sheet 12 is made of a material such as optical glass or quartz glass that does not cause scattering or absorption of light, and its diameter is larger than the diameter of the probe body 2.

[0034] According to the above structure, when the probe body 2 is used, the provision of the protective sheet 12 can effectively reduce the contamination of the probe body 2 by dust, impurities, flies, insects, etc. Since the protective sheet 12 is made of materials such as optical glass or quartz glass, these materials usually have a smooth surface and low adhesion, making it relatively easy to remove dirt, dust or other impurities from the surface.

[0035] In summary, the present invention effectively protects the probe body 2 through the protective assembly, preventing collisions with external objects and reducing the risk of damage to the probe body 2. Furthermore, it seals the gaps between the protective ring 3 and the pulse energy meter body 1, and between the protective cover 6 and the protective ring 3, preventing dust and impurities from affecting the probe body 2 and extending the service life of the probe body 2. Furthermore, the protective assembly is easy to install, requiring only rotating the protective ring 3, improving operational efficiency and convenience while saving both human and material resources.

[0036] The above is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
