The present invention relates to the field of optical element storage, and more particularly to an optical element storage device and mechanism.
Due to the characteristics of the material of optical elements, their surfaces can easily be damaged, which affects the experimental accuracy. Therefore, optical elements need to be well protected during storage and transportation, on the one hand, to isolate dust, grease and other contaminations from the outside, and on the other hand, to protect the elements from abrasion, so as to maximize the service life of the optical elements and reduce damage.
The existing ways to store optical elements include the following ones. One way is to wrap an optical element with dust-free cloth and then put it in plastic foam for packaging and storage. This way provides too rough protection, which easily causes damage and contamination to the surface of the optical element. Another way is to manufacture a simple glass cover and place the optical element in the glass cover. This protection device cannot fix the optical element well, so that the optical element easily shakes especially during transportation, which leads to the collision between the optical element and the glass cover, thus causing abrasion to the optical element.
In view of this, the present invention aims to solve the technical problem of overcoming disadvantages in related art by providing an optical element storage device. The optical element storage device of the present invention has small size, low weight and low cost. An elastic internal fixation type structure is provided in the device, so as to effectively enable energy dissipation and shock absorption, providing maximum level of protection of the optical element, preventing damage to the optical element and prolonging service life of the optical element.
To solve the technical problem mentioned above, the present invention provides an optical element storage device including:
Preferably, a positioning block is provided on the pressing block, the shape of the positioning block matching with that of the first groove. The positioning block is clamped in the first groove when the top cover and the base are connected with each other.
Preferably, a first connecting pillar is provided at the bottom of the fourth groove and a first through hole is axially provided on the first connecting pillar.
Preferably, an elastic member is provided between the pressing block and the bottom of the fourth groove and sleeved on the first connecting pillar.
Preferably, an accommodating cavity is provided on the pressing block and is configured to accommodate the first connecting pillar.
Preferably, a second connecting pillar is provided in the accommodating cavity and a second through hole is axially provided on the second connecting pillar. The first through hole is configured to accommodate the second connecting pillar.
Preferably, a fifth groove and a sixth groove are symmetrically provided on two sides of the first groove The fifth groove and the sixth groove are in communication with the first groove.
Preferably, a chamfer is provided at the top of the fifth groove and the sixth groove.
Preferably, a first thread is provided on the base and a second thread is provided in the third groove. The top cover is thread-connected with the base.
The present invention further provides an optical element storage mechanism including a tray and an optical element storage device described above. Multiple placing portions are provided on the tray. The optical element storage device is placed on the placing portions.
The aforementioned technical solution of the present invention has the following advantages compared with related art.
In an optical element storage device of the present invention, a base and a cover body unit are provided, the second groove for placing the optical element to be stored is provided in the base, a boss is symmetrically provided in the second groove, and the breakup tab of the optical element to be stored can be placed on the boss. In the process of buckling the top cover to the base, the pressing block is subjected to pressure by the top cover. Since the projected area of the pressing block on the base is larger than the sectional area of the first groove, the pressing block is stopped by the first groove when it is approaching the optical element to be stored so as not to be in contact with the optical element to be stored. As such, a rotary internal fixation type structure can be formed. The optical element storage device of the present invention has a simple structure and is easy to be carried, and can store and transport the optical element stably while enabling energy dissipation and shock absorption, thereby providing maximum level of protection of the optical element, and preventing damage to the surface of the optical element.

In the process of buckling the top cover to the base, the pressing block is subjected to pressure by the top cover. Since the projected area of the pressing block on the base is larger than the sectional area of the first groove, the pressing block is stopped by the first groove when it is approaching the optical element to be stored so as not to be in contact with the optical element to be stored. As such, a rotary internal fixation type structure can be formed. The optical element storage device of the present invention has a simple structure and is easy to be carried, and can store and transport the optical element stably while enabling energy dissipation and shock absorption, thereby providing maximum level of protection of the optical element, and preventing damage to the surface of the optical element.
Further, a positioning block 31 is provided on the pressing block 3. The shape of the positioning block 31 matches with that of the first groove 11, so that in the process of buckling the top cover 2 to the base 1, the positioning block 31 and the first groove 11 are gradually approaching each other. Before the positioning block 31 is clamped in the first groove 11, the top cover 2 is rotatably adjusted, so that the positioning block 31 is rotated to the first groove 11 and clamped in the first groove 11. In this embodiment, the positioning block 31 has a squared shape, and the first groove 11 is a squared groove of a shape matching with that of the positioning block 31. As such, in the process of screwing the top cover 2 to the base 1, the positioning block 31 can rotatably position the first groove 11, forming a complete optical element storage device of rotary positioning and internal fixation type.

The diameter of the end cap 42 is greater than that of the first through hole 24. With such an arrangement, the first connecting pillar 23 can stop the end cap. The end cap 42 is located between the first connecting pillar 23 and the pressing block 3. The end cap 42 is connected with the spring at the same time. The spring gland can provide buffering between the first connecting pillar 23 and the pressing block 3 to reduce the impact force, providing further protection.
It is to be noted that an accommodating cavity 32 is provided on the pressing block 3 and can accommodate the first connecting pillar 23 and the spring gland.
Specifically, a second connecting pillar 33 is provided in the accommodating cavity 32. A second through hole 34 is axially provided on the second connecting pillar 33.

The fifth groove 15 and the sixth groove 16 are in communication with the first groove 11. The fifth groove 15 and the sixth groove 16 are also provided on the base 1. The fifth groove 15 and the sixth groove 16 can facilitate picking and placing of the optical element to be stored by the operator. The fifth groove 15 and the sixth groove 16 are symmetrically arranged and have a chamfer on the top, which is more ergonomic and facilitates picking and placing of the optical element to be stored from both sides, preventing contamination to the optical element.
Specifically, a recess 35 is further provided on the positioning block 31. The shape of the recess 35 matches with that of the optical element to be stored. A bottom plate is provided at the bottom of the base 1. The diameter of the bottom plate is greater than that of the base. When the cover body unit is being rotated, the bottom plate can facilitate holding by the user. In addition, the dust proof performance of the optical element storage device can be further improved.
It is to be noted that the shape of the second groove 12 matches with that of the optical element to be stored and can be altered according to the parameters of the optical element to be stored so as to be adapted to optical elements of various sizes and shapes.
Specifically, a first thread 14 is provided all around the base 1. A second thread 20 is provided on an inner all of the third groove 21. With such an arrangement, the base 1 and the top cover 2 can be thread-connected with each other, so that when the base 1 is screwed and locked with the top cover 2, on the one hand, stability of the optical element to be stored can be ensured, and on the other hand, sealing between the top cover 2 and the base 1 can be improved.

The fifth groove 15 and the sixth groove 16 both have a diameter of 20 mm, so that the user can pick and place the circular optical element with two fingers and cover the cover body unit on the base 1. In the process of screwing the thread, the pressing block 3 rotates under a force and approaches the position of the circular optical element. At this time, the first groove 11 and the positioning block 31 are automatically rotated and positioned and the positioning block 31 is clamped in the first groove 11, whereupon the pressing block 3 stops the movement, forming a complete optical element storage device of rotary positioning and internal fixation type, while enabling energy dissipation and shock absorption, thereby providing maximum level of protection of the surface of the optical element from scratch and abrasion.
The present invention further discloses an optical element storage mechanism including a tray and multiple optical element storage devices described above.
