Description

Technical Field

[0001] The utility model relates to the technical field of optical equipment, in particular to a uniform light splitting system. Background Art

[0002] The integrating sphere uniform spectroscopic system is a device that evenly scatters light from a light source. It is widely used in various optical measurements and experiments. It evenly scatters light in all directions after multiple reflections from the internal light, forming a uniform light field. This uniform light source property makes it play an important role in fields such as optical measurement, color measurement, and spectral analysis.

[0003] The integrating sphere uniform spectroscopic system basically consists of an integrating sphere, a host computer and a control computer. When the integrating sphere is in use, it is necessary to turn on the integrating sphere, then install the lamp on the lamp holder, turn off the integrating sphere and power on for testing. However, in the actual operation process, when the integrating sphere is turned on to install the lamp, the staff needs to enter the integrating sphere to perform the operation. During the staff's repeated operations, it is easy to cause the inside of the integrating sphere to be contaminated. In addition, the long-term opening of the integrating sphere is also easy to contaminate the integrating sphere, and even collision with the integrating sphere causes internal damage, affecting the test effect of the integrating sphere.

The movable hemisphere 2 slides on the sliding base 3, and a mounting rod 6 is installed in the fixed hemisphere 1, and a lamp holder 10 is installed at the bottom end of the mounting rod 6.

[0031] Further, please refer to Figure 3-4 The embodiment of the present invention provides a uniform light splitting system, in which a mounting seat 7 is installed in the fixed hemisphere 1, a mounting rod 6 is rotatably installed in the mounting seat 7, an expansion pop-up device 8 is installed in the mounting seat 7, and the movable hemisphere 2 slides and expands, and the expansion pop-up device 8 is driven to drive the mounting rod 6 to rotate out of the fixed hemisphere 1. It should be noted that in the embodiment of the present invention, by driving the expansion pop-up device 8, when the movable hemisphere 2 is opened, the mounting rod 6 can automatically rotate out of the fixed hemisphere 1, and when the movable hemisphere 2 is closed, the mounting rod 6 automatically rotates back into the fixed hemisphere 1, so that the installation of the lamp no longer requires entering the movable hemisphere 2 or the fixed hemisphere 1, avoiding the problem of damage or contamination to the interior thereof, and at the same time providing a larger space for the replacement of the lamp, facilitating operation.

[0032] Please refer to Figure 5-6 Specifically, a sealing edge 4 is mounted on the fixed hemisphere 1, a closing ring 5 is movably mounted on the movable hemisphere 2, and an auxiliary sealing device 9 is installed between the closing ring 5 and the movable hemisphere 2. The movable hemisphere 2 slides and expands, driving the auxiliary sealing device 9 to seal the fixed hemisphere 1. It should be noted that in this embodiment of the utility model, the auxiliary sealing device 9 can be provided to seal the sealing edge 4 when the mounting rod 6 is rotated out of the fixed hemisphere 1, thereby preventing contamination when the movable hemisphere 2 is opened and closed.

[0033] Further, please refer to Figure 3-4 The present invention provides a uniform light splitting system. The deployable pop-up device 8 includes a rotating deployable base 801, which is rotatably mounted within a mounting base 7. The mounting rod 6 is mounted on the rotating deployable base 801. The rotating deployable base 801 drives the mounting rod 6 to rotate. It should be noted that in the present invention, the rotating deployable base 801 rotates within the mounting base 7 and simultaneously drives the mounting rod 6 to rotate.

[0034] More specifically, in the embodiment of the present invention, a mounting cavity 806 is provided in the rotating and unfolding seat 801, a mounting shaft 807 is rotatably mounted in the mounting cavity 806, the mounting shaft 807 is mounted in the mounting seat 7, and the rotating and unfolding seat 801 rotates on the mounting shaft 807 through the mounting cavity 806. It should be noted that in the embodiment of the present invention, when the rotating and unfolding seat 801 is rotated to be unfolded or closed, it rotates on the mounting shaft 807 through the mounting cavity 806;

[0035] It should be emphasized that the cross-section of the installation cavity 806 is thin at both ends and thick in the middle. The middle part is used to place the rotary torsion spring 808, and the thinner parts at both ends are the installation positions of the installation shaft 807, ensuring the normal rotation of the installation shaft 807 and the installation stability of the rotary torsion spring 808.

[0036] More specifically, in the embodiment of the present invention, a rotary torsion spring 808 is mounted on the mounting shaft 807, the other end of which is mounted on the inner wall of the mounting cavity 806. The rotary torsion spring 808 drives the rotating and deploying seat 801 to rotate, thereby rotating the mounting rod 6 out of the fixed hemisphere 1. It should be noted that in the embodiment of the present invention, the rebound force of the rotary torsion spring 808 can help the rotating and deploying seat 801 to return to its original position.

[0037] Please continue to refer to Figure 3-4 More specifically, in the embodiment of the present invention, a lifting hole 809 is provided on the mounting seat 7, and a push rod 802 is movably installed in the lifting hole 809, and a pressing ball 803 is installed at the bottom end of the push rod 802, so that the push rod 802 moves and squeezes the rotating and deploying seat 801 through the pressing ball 803 to rotate. It should be noted that in the embodiment of the present invention, the push rod 802 moves and squeezes the rotating and deploying seat 801 through the pressing ball 803 to rotate, and when the rotating and deploying seat 801 rotates, the push rod 802 is driven back to its original position by the pressing ball 803, which can effectively reduce the friction between the pressing ball 803 and the rotating and deploying seat 801. It should be emphasized that the pressing ball 803 can also be replaced by a rolling wheel or other structure that can reduce friction. The specific selection is the best to meet the actual use requirements.

[0038] More specifically, in the embodiment of the present invention, a pressing seat 804 is mounted on the top of the push rod 802. The top side of the pressing seat 804 is curved, and the movable hemisphere 2 moves by closing and squeezing the pressing seat 804. It should be noted that in the embodiment of the present invention, during the closing process of the movable hemisphere 2, the curved top side of the pressing seat 804 facilitates the pressing of the movable hemisphere 2 against the pressing seat 804.

[0039] Please continue to refer to Figure 3-4 More specifically, in the embodiment of the present invention, a lamp holder switch 805 is installed in the mounting base 7. The lamp holder switch 805 is electrically connected to the lamp holder 10. The extrusion base 804 is forced downward to trigger the lamp holder switch 805. It should be noted that in the embodiment of the present invention, the lamp holder switch 805 is automatically turned on and off by the upward and downward movement of the extrusion base 804, thereby automatically turning the lamp holder 10 on and off, further ensuring the safety of the lamp holder 10.

[0040] Further, please refer to Figure 5-6 In an embodiment of the present invention, a uniform light splitting system is provided. The auxiliary sealing device 9 includes a movable sealing ring 901. A sealing sleeve 902 is connected to one side of the movable sealing ring 901. The sealing sleeve 902 is connected to the sealing ring 5. The movable sealing ring 901 moves to close with the sealing edge 4, driving the sealing sleeve 902 to expand. It should be noted that in the embodiment of the present invention, when the movable sealing ring 901 is expanded, the foldable sealing sleeve 902 is also expanded, which can further enhance the sealing effect.

[0041] Please continue to refer to Figure 5-6 Specifically, in the embodiment of the present invention, a plurality of push racks 903 are installed in an annular manner with equal spacing on the closed ring 5. The plurality of push racks 903 are all installed on the movable closed ring 901. Two limiting plates 905 are installed on the sliding base 3. When the movable hemisphere 2 is unfolded, the two push racks 903 at the corresponding positions are driven to be squeezed and moved by the two limiting plates 905.

[0042] In addition, a return spring 904 is installed on the push frame 903, and the other end of the return spring 904 is installed on the closing ring 5. It should be noted that in the embodiment of the present invention, when the movable hemisphere 2 is opened, the closed ring 5 is driven to start synchronously, so that the two push frames 903 at the corresponding positions are pushed by the limiting plate 905. At this time, the push frame 903 drives the movable closing ring 901 to move and seal the edge 4, thereby preventing the problem of contaminants entering the fixed hemisphere 1 or the movable hemisphere 2 when opening and closing. In addition, when the push frame 903 moves, the return spring 904 is stressed.

[0043] It should be emphasized that in this embodiment, the movable closing ring 901 is made of elastic rubber material, so that when it encounters the mounting rod 6 during the closing process, it can play a sealing role through deformation, while not affecting the use of the mounting rod 6 or causing damage to the mounting rod 6.

[0044] Further, please refer to Figure 1 In the embodiment of the present invention, a uniform light splitting system is provided. A sliding block 11 is mounted on the bottom side of the movable hemisphere 2. The sliding block 11 is slidably mounted on the sliding base 3. It should be noted that in the embodiment of the present invention, when the movable hemisphere 2 moves, the sliding block 11 slides on the sliding base 3, so that the movable hemisphere 2 maintains horizontal movement.

[0045] In summary, the working principle of the uniform light splitting system provided by the embodiment of the present invention is:

[0046] When the movable hemisphere 2 is opened, the movable hemisphere 2 slides open on the sliding base 3 through the sliding block 11, and the movable hemisphere 2 is separated from the squeezing seat 804. At this time, the rotating expansion seat 801 is driven to rotate under the rebound force of the rotary torsion spring 808, so that the rotating expansion seat 801 pushes the push rod 802 upward through the pressing ball 803, and then the push rod 802 drives the squeezing seat 804 to move upward. At this time, the squeezing seat 804 is separated from the lamp holder switch 805, so that the lamp holder 10 is powered off. At the same time, when the rotating expansion seat 801 is rotated, it drives the lamp holder 10 to rotate out of the fixed hemisphere 1 through the mounting rod 6. At this time, the lamp that needs to be tested can be loaded and unloaded conveniently, and the power has been cut off, making the loading and unloading of the lamp safer; similarly, when the movable hemisphere 2 is closed, the squeezing seat 804 moves downward, so that the mounting rod 6 drives the lamp holder 10 to be automatically retracted into the fixed hemisphere 1, and the squeezing seat 804 squeezes the lamp holder switch 805 to turn on, realizing automatic power on;

[0047] In addition, when the movable hemisphere 2 is opened, the driving closed circle 5 is started synchronously, so that the two pushing frames 903 at the corresponding positions are pushed by the limiting plate 905. At this time, the pushing frame 903 drives the movable closed circle 901 to move and seal the edge 4, thereby preventing contaminants from entering the fixed hemisphere 1 or the movable hemisphere 2 during the process of loading and unloading the lamp, thereby affecting the test effect.

[0048] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
