Description
本發明主要係揭示一種固定裝置，尤指利用第一固定框與第二固定框同時緊迫固定光學元件，以防止光學元件於內轉動或徑向移動的光學元件的固定裝置。 The invention mainly discloses a fixing device, in particular a fixing device for an optical component which uses the first fixing frame and the second fixing frame to simultaneously fix the optical component to prevent the optical component from rotating or moving radially.
目前一般市面上所常見的透鏡裝置或是面鏡裝置，例如放大鏡、眼鏡或平面鏡(俗稱鏡子)、凸面鏡、凹面鏡等等，皆屬於採用透鏡或面鏡等光學元件作為產品的裝置，都需要使光學元件固定在預定的載體上，固定方式可以分為黏合或卡裝等手段。 At present, lens devices or mirror devices commonly used in the market, such as magnifying glasses, glasses or plane mirrors (commonly known as mirrors), convex mirrors, concave mirrors, etc., all belong to devices using optical components such as lenses or mirrors, and all need to be made. The optical component is fixed on a predetermined carrier, and the fixing manner can be divided into a bonding or a carding.
以黏合方式將光學元件固定在載體的手段來說，需先於載體上或光學元件上塗膠然後再於載體上安裝光學元件，接著清潔多出或溢出的黏膠，然後經一段時間等待黏膠乾固，之後再次確認載體與光學元件之間是否有穩固黏合，若仍未穩固，就要再次補膠重新黏合，因此整個安裝手段需要較多手續及較多的時間，非常耗費人工而有浪費生產成本的問題。 The means for fixing the optical component to the carrier by bonding means that the optical component is applied to the carrier or the optical component, and then the optical component is mounted on the carrier, and then the excess or overflowing adhesive is cleaned, and then the adhesive is waited for a while. Drying, then confirming whether there is a firm bond between the carrier and the optical component. If it is still not stable, it is necessary to re-adhesive and re-bond. Therefore, the entire installation method requires more procedures and more time, which is labor-intensive and wasteful. The problem of production costs.
而且此種黏合的方式通常導致無法再次拆卸光學元件，故一旦發生光學元件破損時，整個產品即屬報廢品而被丟棄，沒有再次利用的可能性，不符環保要求。 Moreover, this type of bonding usually results in the inability to disassemble the optical component again. Therefore, in the event of breakage of the optical component, the entire product is discarded and discarded, and there is no possibility of reuse, which does not meet environmental requirements.
以另一種方式來說，其係直接將光學元件卡裝在載體上，相較於前述黏合的方式，利用卡裝方式可以讓安裝手 續變得簡便，而且較為省時。 In another way, it directly attaches the optical component to the carrier, and the mounting method can be used by the mounting method compared to the manner of bonding described above. The continuation is simple and time-saving.
但是載體若為彈性較差的材料所製成時，安裝光學元件的過程中，需以較大的力量壓擠光學元件，人工組裝時不但費力而且容易造成光學元件破裂，若載體由彈性較佳的材料製成，光學元件雖然容易安裝至載體上，但也容易脫落。 However, if the carrier is made of a material having poor elasticity, in the process of mounting the optical component, the optical component needs to be squeezed with a large force, and the manual assembly is not only laborious but also easily causes the optical component to be broken, if the carrier is elastically better. Made of materials, the optical components are easy to attach to the carrier, but they are easy to fall off.
特別是在熱帶地區或是溫度高的環境下，卡裝的載體會因受熱膨脹導致載體孔徑擴大，使得載體與光學元件之間的間隙增加，故容易發生光學元件於載體內旋轉或是徑向移動的缺點，甚至造成光學元件脫出載體的問題。 Especially in the tropical region or in a high temperature environment, the carrier of the card is enlarged due to thermal expansion, and the gap between the carrier and the optical element is increased, so that the optical element is likely to rotate or radially in the carrier. The disadvantage of moving, even causing the optical component to come out of the carrier.
有鑑於上述先前技術的問題無法有效的解決與克服，因此本申請人提出本專利申請，以解決前述問題點。 In view of the above problems of the prior art, which cannot be effectively solved and overcome, the present applicant has filed this patent application to solve the aforementioned problems.

而且即使於熱帶地區受熱導致固定裝置徑向膨脹時，因所述的最小軸向距離小於光學元件與第一緊迫部相接觸的位置至光學元件與第二緊迫部相接觸的位置之間的光學元件厚度，故第一固定框的第一緊迫部與第二固定框的第二緊迫部仍然能夠同時緊迫固定光學元件，依然能夠防止光學元件於第一固定框與第二固定框內轉動或徑向移動，持續達到穩固緊迫光學元件的效果，進一步就是具有提高產品使用壽命的優點。 Moreover, even if the heating device is radially expanded to cause radial expansion of the fixture, the minimum axial distance is less than the optical position between the position where the optical element contacts the first pressing portion and the position where the optical element contacts the second pressing portion.

於本實施例中，光學元件90的兩個表面92、94皆為凸面(即兩個光學表面)，屬於雙凸透鏡，當固定裝置10安裝光學元件90後，即可作為放大鏡供使用者使用，當然光學元件90也可以是平面鏡等具反射效果的鏡子。而且，即使於熱帶地區受熱導致固定裝置10徑向膨脹時，因所述的最小軸向距離Y小於光學元件90與第一緊迫部24相接觸的位置至光學元件90與第二緊迫部34相接觸的位置之間的光學元件90厚度T，故第一固定框20的第一緊迫部24與第二固定框30的第二緊迫部34仍然能夠同時緊迫固定光學元件90，依然能夠防止光學元件90於第一固定框20與第二固定框30內轉動或徑向移動，持續達到穩固緊迫光學元件90的效果，進一步就是具有提高產品使用壽命的優點。 In this embodiment, both surfaces 92 and 94 of the optical component 90 are convex surfaces (ie, two optical surfaces), and belong to the lenticular lens. When the optical component 90 is mounted on the fixing device 10, it can be used as a magnifying glass for the user. Of course, the optical element 90 can also be a reflective mirror such as a mirror. Moreover, even if the fixing device 10 is radially expanded due to heat in the tropics, the minimum axial distance Y is smaller than the position where the optical element 90 is in contact with the first pressing portion 24 to the optical element 90 and the second pressing portion 34. The thickness of the optical element 90 between the contact positions is such that the first pressing portion 24 of the first fixing frame 20 and the second pressing portion 34 of the second fixing frame 30 can still simultaneously fix the optical element 90, and the optical element can still be prevented. The rotation or radial movement of the first fixing frame 20 and the second fixing frame 30 continues to achieve the effect of stably pressing the optical element 90, and further has the advantage of improving the service life of the product.

The second joint portion 36 of the second fixing frame 20 is formed with an L-shaped shape. Card slot 361, said The latching slot 361 is configured to receive the elastic barb 261 and fasten the elastic barb 261 in the latching slot 361. The second fixing frame 30 is provided with an opening 362 which is connected to the locking groove 361 and opposite to the elastic barb 261. The opening 362 is for the tool to extend to release the fastening between the elastic barb 261 and the locking groove 361. relationship. Therefore, when the optical element 90 needs to be replaced, the first fixing frame 20 and the second fixing frame 30 of the fixing device 10 of the present invention can be uncoupled to achieve the effect of replacing the optical element 90.
由於本發明固定裝置10利用第一結合部26與第二結合部36相互結合且能夠再次拆卸的設計，完全無需使用膠合的技術，故免除了等待膠合劑乾燥的工時，更去除了拆解時可能發生破壞膠合處的問題，有效的降低了生產成本，亦提高了產品的使用壽命。 Since the fixing device 10 of the present invention utilizes the design that the first joint portion 26 and the second joint portion 36 are combined with each other and can be detached again, the glue-free technique is completely eliminated, so that the workmanship of waiting for the glue to dry is eliminated, and the disassembly is removed. At the same time, the problem of damaging the glue joint may occur, the production cost is effectively reduced, and the service life of the product is also improved.
本實施例中，固定裝置10還包括有一個以軟質材料製成的緩衝框40，緩衝框40包覆於第二固定框30之外，緩衝框40能夠吸收外界硬物的碰撞，有效防止光學元件90因震動而脫離的問題，並且還能夠避免光學元件90破裂的情況發生，達到延長產品使用壽命的效果。本實施例中，緩衝框40採用橡膠製成，而第一固定框20與第二固定框30採用塑膠製成。 In this embodiment, the fixing device 10 further includes a buffer frame 40 made of a soft material. The buffer frame 40 is wrapped around the second fixing frame 30. The buffer frame 40 can absorb the collision of external hard objects and effectively prevent the optical. The problem that the component 90 is detached due to vibration, and also the occurrence of cracking of the optical component 90 can be avoided, and the effect of prolonging the service life of the product can be achieved. In this embodiment, the buffer frame 40 is made of rubber, and the first fixing frame 20 and the second fixing frame 30 are made of plastic.
參照圖七，本發明固定裝置10還具有更進一步的好處，當光學元件90因研磨時導致光學元件90外周邊91尺寸略小時，此光學元件90仍能夠正常的安裝於本發明的固定裝置10內，不會發生因光學元件90研磨後公差過大而判定為瑕疵品的情況。 Referring to Fig. 7, the fixing device 10 of the present invention has the further advantage that when the optical member 90 causes the outer periphery 91 of the optical member 90 to be slightly smaller in size due to grinding, the optical member 90 can still be normally mounted to the fixing device 10 of the present invention. In the case where the optical element 90 is too large in tolerance after polishing, it is determined that the product is defective.
因為本發明固定裝置10的技術手段係利用第一緊迫部24與第二緊迫部34之間的最小軸向距離Y小於光學元件90與第一緊迫部24相接觸的位置至光學元件90與第二緊迫部34相接觸的位置之間的光學元件90厚度T，使固定裝置10安裝光學元件90後，即使第一緊迫槽23的底部25與第二緊迫槽33的底部35皆未接觸光學元件90的外周邊91，亦即第一緊迫槽23的底部25與第二緊迫槽33的底部35與光學元件90的外周邊91之間保持有間隙時，第一固定框20的第一緊迫部24與第二固定框30的第二緊迫部34仍然能夠同時緊迫固定光學元件90，防止光學元件90於第一固定框20與第二固定框30內轉動或徑向移動，達到穩固緊迫光學元件90的效果，有效解決光學元件90因加工研磨產生不同尺寸公差的問題，進一步減少了生產過程中產品的瑕疵率，相對的就是提高了產量，達到節省成本的優點。 Because the technical means of the fixing device 10 of the present invention utilizes the minimum axial distance Y between the first pressing portion 24 and the second pressing portion 34 to be smaller than the position where the optical element 90 is in contact with the first pressing portion 24 to the optical element 90 and the The thickness T of the optical element 90 between the positions where the two pressing portions 34 are in contact, so that after the fixing device 10 is mounted with the optical element 90, even if the bottom portion 25 of the first pressing groove 23 and the bottom portion 35 of the second pressing groove 33 are not in contact with the optical element The first pressing portion of the first fixing frame 20 when the outer periphery 91 of the 90, that is, the bottom portion 25 of the first pressing groove 23 and the bottom portion 35 of the second pressing groove 33 and the outer periphery 91 of the optical member 90 are maintained with a gap therebetween 24 and the second pressing portion 34 of the second fixing frame 30 can still firmly fix the optical element 90 at the same time, preventing the optical element 90 from rotating or moving radially in the first fixing frame 20 and the second fixing frame 30 to achieve a stable pressing optical component. The effect of 90 effectively solves the problem that the optical component 90 has different dimensional tolerances due to machining and grinding, further reducing the defect rate of the product in the production process, and relatively increasing the output and achieving the cost saving advantage.
參照圖八，為本發明固定裝置10的第二個實施例，本實施例與前述實施例大致相同，其差異處在於本實施例的第一固定框20與第二固定框30的結合方式不同。 Referring to FIG. 8 , a second embodiment of the fixing device 10 of the present invention is substantially the same as the foregoing embodiment, and the difference is that the first fixing frame 20 and the second fixing frame 30 of the embodiment are combined differently. .
於本實施例中，第一固定框20的第一結合部27於第一固定框20的外周圍22設有外螺紋271，第二固定框30的第二結合部37內相對於第一固定框20的外螺紋271處設有內螺紋371，所述第一固定框20的外螺紋271能夠螺接於第二固定框30的內螺紋371。藉此，當遭遇需更換光學元件90的情況時，本發明固定裝置10的第一固定框20 與第二固定框30能夠解除結合關係，達到更換光學元件90的效果。其餘優點則如同前述的第一個實施例，故於此不再加以贅述。 In the present embodiment, the first joint portion 27 of the first fixing frame 20 is provided with an external thread 271 at the outer periphery 22 of the first fixing frame 20, and the second joint portion 37 of the second fixing frame 30 is fixed relative to the first portion. The external thread 271 of the frame 20 is provided with an internal thread 371 , and the external thread 271 of the first fixing frame 20 can be screwed to the internal thread 371 of the second fixing frame 30 . Thereby, the first fixing frame 20 of the fixing device 10 of the present invention is encountered when the optical element 90 needs to be replaced. The bonding relationship with the second fixing frame 30 can be released, and the effect of replacing the optical element 90 can be achieved. The remaining advantages are the same as the first embodiment described above, and thus will not be further described herein.
惟上所述者，僅為本發明之較佳實施例而已，當不能以之限定本發明實施之範圍，故舉凡數值之變更或等效元件之置換，或依本發明申請專利範圍所作之均等變化與修飾，皆應仍屬本發明專利涵蓋之範疇。 The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, so that the numerical value is changed or the equivalent element is replaced, or the equivalent of the scope of the patent application of the present invention. Changes and modifications are still within the scope of the invention patent.
