Technical Field

[0001] This utility model relates to the field of optical film fixing technology, and in particular to an optical film fixing component. Background Technology

[0002] In actual production operations, after bending the lugs on the optical film, improper post-processing, improper placement, or other external force factors often cause deformation of the bending angle of the lugs, which greatly reduces the product yield. Utility Model Content

[0015] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0016] An optical film fixing component of this utility model, with the help of a base plate and a fixing frame, uses a first recessed groove on the fixing frame to accommodate the lugs on the optical film, thereby limiting the lugs of the optical film within the first recessed groove, avoiding bending angle deformation of the lugs, and improving product yield.

[0017] Furthermore, by creating a second recess on the fixed frame, corresponding support is provided for the base plate and the fixed frame, thereby providing more stable support for the optical film placed on the fixing component. Simultaneously, a third recess is created on the left and right side walls of the fixed frame to facilitate manual placement and removal. The structure is simple and lightweight.

[0024] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] See Figures 1 to 3 The optical film fixing component includes a base plate 1, a fixing frame 2, and a first sink 4.

[0026] Specifically, the base plate 1 and the fixing frame 2 are integrally connected; more specifically, the edges of the fixing frame 2 and the base plate 1 are integrally connected. The size of the base plate 1 can be reasonably arranged and adjusted according to actual production needs and the size of the optical film 3. Generally speaking, the size of the base plate 1 is consistent with the size of the optical film 3 to ensure that when the optical film 3 is placed on the base plate 1, it can be stably limited by the fixing frame 2, ensuring that it will not move freely within the fixing frame 2.

[0027] Regarding the aforementioned first recessed groove 4, in this embodiment of the invention, it is formed on the inner sidewall of the fixing frame 2 to accommodate the lug 301 on the optical film 3. It is worth noting that in this embodiment of the invention, the aforementioned first recessed groove 4 is configured as an inclined groove, see reference [reference needed]. Figure 3 The inclined angle of the groove relative to the base plate 1 is 135°. Since the bending angle range of the lug 301 on the optical film material 3 is generally 95°±5°, in this embodiment of the present invention, the inclined angle of the first groove 4 is set to be slightly larger than the bending angle of the lug 301, so as to ensure that when the lug 301 is placed in the first groove 4, its bent part will not be squeezed and deformed by the first groove 4.

[0028] Of course, the angle of inclination of the first settling tank 4 relative to the bottom plate 1 can be reasonably adjusted according to actual production, and the number and position of the first settling tank 4 can also be changed according to production needs, and are not limited to the above implementation method.

[0029] Furthermore, in this embodiment, the lower end face of the first sinking groove 4 is set to be slightly lower than the bottom plate 1, that is, the first sinking groove 4 is horizontally lower than the bottom plate 1, which can better accommodate the lug 301 and prevent the bent part of the lug 301 from being squeezed by the lower end face of the first sinking groove 4.

[0030] Regarding the aforementioned lug 301, in this embodiment of the present invention, it is located on the same side of the optical diaphragm 3 and is integrally connected with the optical diaphragm 3.

[0031] In addition, in this embodiment of the invention, several second recessed grooves 5 are provided on the outer peripheral wall of the aforementioned fixed frame 2. In the prior art, the outer periphery of the fixed frame 2 does not have recessed grooves. In this embodiment of the invention, the second recessed grooves 5 cooperate with the aforementioned base plate 1 to provide corresponding support for the fixed frame 2, thereby providing stable support for the optical film 3 and the lug 301 within the accommodating cavity formed by the base plate 1 and the fixed frame 2. The number of second recessed grooves 5 can be reasonably arranged as needed. Furthermore, the lower end face of the second recessed groove 5 is integrally connected to a plate material identical to the base plate 1. The lower end face of the second recessed groove 5 is combined with the plate material to strengthen the fixed frame 2.

[0032] In this embodiment of the present invention, a third sink 6 is also provided on the inner sidewalls of the left and right ends of the aforementioned fixed frame 2 to facilitate manual placement and removal of the optical film, thereby improving the corresponding ease of operation.

[0033] In addition, in this embodiment, a buffer cavity is formed at each of the four corners of the accommodating space of the optical film 3 enclosed by the base plate 1 and the fixing frame 2. The buffer cavity is used to protect the four corners of the optical film 3 from damage.

[0034] In this embodiment, several reinforcing grooves (not shown in the figure) are also provided on the outer wall of the fixed frame 2. The reinforcing grooves can increase the rigidity and strength of the fixed frame 2 to a certain extent. The depth and size of the reinforcing grooves can be adjusted reasonably as needed.

[0035] It should be noted that the depth of the first sinker 4, the second sinker 5, and the third sinker 6 can be the same or different, or the size of the sinker 4, the second sinker 5, and the third sinker 6 can be the same or different. The specific situation can be adjusted according to the actual production needs, as long as it can ensure that the entire fixing component provides stable support and fixation for the optical diaphragm 3 and its lug 301.

[0036] In this embodiment, the optical diaphragm fixing component is integrally blow-molded, and a hollow structure is formed inside the fixing frame 2. The hollow structure can reduce the weight of the fixing component and reduce the overall structural burden. Secondly, by reasonably setting the corresponding hollow structure, the strength of the fixing component can be improved, the stress distribution of the diaphragm can be balanced, and the local stress concentration can be reduced.

[0037] In practical use of this fastener, simply place an optical film 3 that matches the size of the fastener into the receiving cavity, ensuring that the lug 301 on the bottom optical film 3 abuts against the end face of the first recess 4. Then, stack optical films 3 one by one on the bottom optical film 3 until the maximum load-bearing capacity of the fastener is reached. This achieves the fastening of the optical film 3 and its lug 301, ensuring that the bending angle of the lug 301 does not deform. The size of this optical film fastener can be molded according to the size of the optical film 3, offering high adaptability.

[0038] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
