[0033] The following will be described in detail in combination with the accompanying Figures 1-4 The present application will be further described in detail.

[0034] Embodiment:

[0035] A cleaning clamp for small optical filters, with reference to Figure 1 and Figure 2 The cleaning clamp 1 comprises a bottom plate 2 and a cover plate 4, both of which are made of stainless steel in this embodiment. Stainless steel has stable corrosion resistance, ensuring that the cleaning clamp 1 firmly holds the optical filter 3. The bottom plate 2 has a placement groove 5, in which the optical filter 3 is placed. The cover plate 4 covers the placement groove 5 and is fixed to the bottom plate 2. One side of the cover plate 4 abuts one side of the optical filter 3, thereby firmly holding the optical filter 3 in the placement groove 5, preventing the optical filter 3 from loosening or falling off during cleaning, and facilitating subsequent cleaning of the optical filter 3. After the cover plate 4 is placed on the bottom plate 2, a gap 9 is formed between the cover plate 4 and the bottom plate 2, allowing cleaning liquid to enter between the cover plate 4 and the bottom plate 2, thereby effectively cleaning the surface of the optical filter 3.

[0036] With reference to Figure 2 and Figure 3 The bottom plate 2 comprises a storage area 6 and a hollow area 7. After hollowing out part of the area of the bottom plate 2 to form the hollow area 7, the area around the hollow area 7 of the bottom plate 2 forms the storage area 6. The placement grooves 5 are symmetrically arranged on both sides of the hollow area 7. The hollow area 7 is symmetrically provided with two hollow areas 7. Two rows of placement grooves 5 are formed on the storage area 6, which can store more optical filters 3, improving the cleaning efficiency. Each group of placement grooves 5 comprises two placement grooves 5. The optical filter 3 is in a long strip shape. The two ends of an optical filter 3 are placed in a group of placement grooves 5. The area between the two ends of the optical filter 3 is located in the hollow area 7, facilitating the cleaning liquid to clean the surface of the optical filter 3.

[0037] With reference to Figure 2 and Figure 3 The placement grooves 5 are arranged at intervals and along the length direction of the bottom plate 2. The same side of the two adjacent placement grooves 5 is arranged at a certain distance, avoiding the contact between the two optical filters 3, and preventing scratching and other damages. There is a gap between the optical filter 3 and the edge of the hollow area 7, facilitating the side area of the optical filter 3 at the edge to contact the cleaning liquid. In combination with Figure 4 A plurality of protrusions 8 are protrudingly arranged on the storage area 6. The protrusions 8 are located on the same side of the placement grooves 5 on the storage area 6. When the cover plate 4 is placed on the bottom plate 2, the side of the cover plate 4 close to the bottom plate 2 abuts the protrusions 8, ensuring that a gap 9 is formed between the cover plate 4 and the bottom plate 2. The area of the optical filter 3 protruding from the placement groove 5 is located in the gap 9. After the optical filter 3 is placed in the placement groove 5, one side of the optical filter 3 protrudes from the placement groove 5 and is flush with the protrusions 8. The cover plate 4 abuts the protrusions 8 and the optical filter 3, so that the cover plate 4 can firmly fix the optical filter 3 in the placement groove 5, preventing the optical filter 3 from loosening or falling off during cleaning, and facilitating the cleaning of the optical filter 3.

[0038] Reference Figure 2 The width of the placing groove 5 is consistent with the width of the filter 3, so that the cover plate 4 and the bottom plate 2 can stably clamp the filter 3 in the placing groove 5. When the filter 3 is cleaned by ultrasonic cleaning, the filter 3 is clamped in the placing groove 5, so as to prevent the filter 3 from moving and colliding with the side wall of the placing groove 5, thereby avoiding scratches, damage or deformation of the filter 3, and affecting the optical performance of the filter 3.

[0039] Reference Figure 2 And Figure 4 The cover plate 4 is detachably connected with a locking piece 10, the protrusion 8 is provided with a through hole one 11 penetrating through the protrusion 8 and the storage area 6, the cover plate 4 is provided with a through hole two 12 communicating with the through hole one 11, the locking piece 10 is a bolt, the through hole one 11 is a threaded hole, and the locking piece 10 is screwed with the through hole one 11 after penetrating through the protrusion 8, the storage area 6 and the cover plate 4, so as to lock the bottom plate 2 and the cover plate 4, thereby fixing the filter 3.

[0040] The implementation principle of the embodiment of the present application is that the cleaning clamp 1 includes a bottom plate 2 and a cover plate 4, the bottom plate 2 includes a storage area 6 and a hollow area 7, the filter 3 is placed in the placing groove 5 on the storage area 6, the two ends of the filter 3 are located in the placing groove 5, and the area between the two ends of the filter 3 is located at the hollow area 7, so as to facilitate the cleaning liquid to clean the surface of the filter 3, the cover plate 4 covers the placing groove 5 and is fixed with the bottom plate 2, one side of the cover plate 4 abuts against the protrusion 8 and the filter 3, a gap 9 is formed between the cover plate 4 and the bottom plate 2, and the locking piece 10 is screwed with the through hole one 11 and the through hole two 12 after penetrating through the storage area 6 and the cover plate 4, so as to lock the bottom plate 2 and the cover plate 4, thereby fixing the filter 3.
