Description

TECHNICAL FIELD

[0001] The present application relates to the field of telescope technology, in particular to a binocular low-light level telescope and a use method thereof. BACKGROUND

[0002] The binocular low-light level telescope is essentially a binocular telescope designed for low-light scenes, and its principle revolves around maximizing light intake and improving light utilization, i.e., optimizing the direction of light intake and transmission.

[0003] The binocular telescope is composed of two barrels, and the eyepiece, objective lens and light transmission and reflection lenses are installed on the barrels. In order to adjust the distance between the two barrels, a hinge is arranged between the two barrels, and the two barrels rotate around the center of the hinge to change the distance between the two barrels to adapt to people with different binocular distances.

[0004] When the hinge is used to connect the binocular telescope, a nut sleeve is installed on the hinge to lock the barrel. After the nut sleeve locks the barrel, the stability between the two barrels can be ensured. In order to ensure the stability and aesthetics of the binocular telescope assembly, hidden bolts are usually used to fix the hinge during connection and installation. This is not convenient for disassembling and using the binocular telescope when two people want to watch the distant scene at the same time, which has certain defects. SUMMARY

[0048] A bearing collar is fixedly sleeved on the outside of the support rod, and one side of the bearing collar is pressed and fitted against the support plate.

[0049] Another objective of this invention is to provide a method for using a binocular low-light telescope, comprising the following specific steps:

[0050] Step 1: When adjusting the distance between the first and second lens barrels, first rotate the locking collar so that the locking collar and connecting collar no longer squeeze and lock the first and second lens barrels. The first and second lens barrels rotate relative to the connecting collar, changing the distance between the first and second lens barrels. After the distance between the first and second lens barrels is adjusted, rotate the locking collar relative to the connecting collar. Under the action of the limiting shaft, the locking collar moves relative to the axis of the connecting collar, so that the locking collar and connecting collar lock and limit the first and second lens barrels.

[0051] Step 2: When using the first and second lens barrels separately, first loosen the locking collar and connecting collar, squeeze the sealing block, and the sealing block pushes the connecting plate toward the inside of the mounting collar. The drive shaft on the connecting plate engages with the guide groove on the locking block, driving the locking block toward the inside of the mounting hole, so that the locking block separates from the annular groove on the connecting shaft. Then pull out the connecting shaft, and finally pull out the connecting sleeve, so that the first and second lens barrels can be used separately.

[0052] Step 3: When assembling the first and second lens barrels, first align the first and second ear plates on the first and second lens barrels. Then, place the locking collar and connecting collar between the second collar and the second ear plate. Next, insert the connecting sleeve into the interior of the second and first ear plates, and make the first and second locking blocks on the connecting sleeve engage with the connecting collar and the second ear plate respectively. Then, squeeze the sealing block to make the locking block retracted. Finally, insert the connecting shaft until the limiting cap at one end of the connecting shaft fits against the first collar. Release the sealing block. Under the action of the limiting spring, the sealing block drives the connecting plate to reset and move. The connecting plate drives the locking block to slide through the driving shaft, so that one end of the outer wall of the locking block engages with the annular groove on the outside of the connecting shaft. This completes the assembly of the first and second lens barrels.

[0053] The technical effects and advantages of this invention are as follows:

[0054] (1) The present invention utilizes the cooperative use of the first lens barrel, the second lens barrel, the sleeve assembly, the shaft assembly, the locking assembly and the locking component. Under the action of the locking component, the sleeve assembly, the shaft assembly and the locking component can be stably installed between the first lens barrel and the second lens barrel, so that the first lens barrel and the second lens barrel can be used together. By squeezing the locking component, the first lens barrel and the second lens barrel can be quickly separated, so that the first lens barrel and the second lens barrel can be used separately.

[0055] (2) The present invention utilizes the setting method of the locking component, which includes a mounting collar, a locking block and an unlocking unit. Under the limitation of the unlocking unit, the locking block can be stably engaged in the annular groove at the end of the connecting shaft, thereby ensuring the stability of the assembly of the sleeve assembly, shaft assembly and locking component. Moreover, by squeezing the sealing block, the locking block can be separated from the connecting shaft, thereby disassembling it. After disassembly, the locking component can form a whole with the sleeve assembly, and the shaft assembly and locking component can form a whole, thereby improving the integrity of the components after disassembly and reducing the probability of component loss.

[0068] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0069] This invention provides, for example Figures 1-10 The image shows a type of binocular low-light telescope.

[0070] Example 1: Includes a first lens barrel 1, a second lens barrel 2, a sleeve assembly 3, a shaft assembly 4, a locking assembly 5, and a locking component 6. The first lens barrel 1 and the second lens barrel 2 are symmetrically arranged. Both the first and second lens barrels 1 and 2 are equipped with eyepieces, objective lenses, filters, lenses, and reflecting mirrors for telephoto viewing. This is prior art and will not be described in detail here. The sleeve assembly 3 is located between the first lens barrel 1 and the second lens barrel 2. The first and second lens barrels 1 and 2 are rotatably connected by the sleeve assembly 3. That is, the lines connecting the center points of the eyepieces on the first lens barrel 1, the second lens barrel 2, and the sleeve assembly 3 can form a triangle. Rotating the center points of the eyepieces on the first and second lens barrels 1 relative to the center line of the sleeve assembly 3 changes the distance between the first and second lens barrels 1 and 2. The shaft assembly 4 is connected to the sleeve assembly 3. The locking component 5 is located on the sleeve assembly 3. By locking and limiting the shaft assembly 4, the shaft assembly 4 locks and limits the sleeve assembly 3. The compression locking component 5 is used to unlock the shaft assembly 4. That is, pressing the locking component 5 can unlock the shaft assembly 4, so that the shaft assembly 4 and the sleeve assembly 3 can be directly pulled out, thereby completing the disassembly of the first lens barrel 1 and the second lens barrel 2. That is, pressing the locking component 5 and pulling out the shaft assembly 4 and the sleeve assembly 3 can complete the disassembly of the first lens barrel 1 and the second lens barrel 2, which can improve the convenience of disassembling the first lens barrel 1 and the second lens barrel 2. The locking component 6 is set on the shaft assembly 4. The locking component 6 cooperates with the sleeve assembly 3 to lock and limit the first lens barrel 1 and the second lens barrel 2. That is, after the distance between the first lens barrel 1 and the second lens barrel 2 is adjusted, the locking component 6 can lock the first lens barrel 1 and the second lens barrel 2 under the limitation of the sleeve assembly 3, ensuring the stability of the state between the first lens barrel 1 and the second lens barrel 2.

[0071] Furthermore, the sleeve assembly 3 includes a connecting sleeve 31, a first ear plate 32, a second ear plate 33, and a fixing cap 34. The connecting sleeve 31 is disposed between the first lens barrel 1 and the second lens barrel 2. The first ear plate 32 is fixedly connected to one side of the first lens barrel 1 and rotatably sleeved on the outside of the connecting sleeve 31. The second ear plate 33 is fixedly connected to one side of the second lens barrel 2 and rotatably sleeved on the outside of the connecting sleeve 31. The two second ear plates 33 are located on the sides of the first ear plate 32. Thus, under the action of the connecting sleeve 31, the first ear plate 32, and the second ear plate 33, the lens barrel 1 can be fixedly sleeved on the outside of the connecting sleeve 31. The first lens barrel 1 and the second lens barrel 2 are rotatably installed. The fixing cap 34 is fixedly connected to the end of the connecting sleeve 31. The fixing cap 34 can limit one end of the connecting sleeve 31, and the shaft assembly 4 can limit the other end of the connecting sleeve 31, thereby ensuring the stability of the installation of the connecting sleeve 31. The locking assembly 5 is set inside the fixing cap 34. Since the locking assembly 5 is integrated inside the fixing cap 34, the integrity of the parts can be improved when the first lens barrel 1 and the second lens barrel 2 are disassembled, thereby reducing the possibility of the locking assembly 5 becoming scattered when the first lens barrel 1 and the second lens barrel 2 are subsequently disassembled.

[0072] Furthermore, the shaft assembly 4 includes a connecting shaft 41, a limiting cap 42, a first collar 43, and a second collar 44. The outer wall of the connecting shaft 41 is slidably sleeved with the connecting sleeve 31. One end of the outer wall of the connecting shaft 41 is engaged with the inside of the fixing cap 34 via a locking assembly 5. The limiting cap 42 is fixedly connected to the end of the connecting shaft 41. Thus, when one end of the connecting shaft 41 is engaged with the fixing cap 34 via the locking assembly 5, the limiting cap 42 can limit the other end of the connecting sleeve 31, thereby ensuring the stability of the connecting sleeve 31 installation. The first collar 43 and the second collar 44 are respectively fixedly connected to one side of the second lens barrel 2 and the first lens barrel 1. The second ring 44 is staggered around the outside of the connecting shaft 41. The center lines of the first ring 43 and the second ring 44 are located on the center line of the connecting shaft 41. The center lines of the first ear plate 32 and the second ear plate 33 are located on the center line of the connecting sleeve 31. The connecting shaft 41 is sleeved inside the connecting sleeve 31, so that the center line of the connecting shaft 41 coincides with the center line of the connecting sleeve 31, and thus the center lines of the first ring 43 and the second ring 44 coincide with each other, so as not to affect the rotation adjustment of the first lens barrel 1 and the second lens barrel 2. The first ring 43 and the second ring 44 are located between the limit cap 42 and the locking assembly 6.

[0073] Specifically, the locking assembly 6 includes a connecting collar 61, a locking collar 62, and a limiting shaft 63. The connecting collar 61 is slidably sleeved on the outside of the connecting shaft 41, and the connecting sleeve 31 can engage and limit the connecting collar 61 to prevent it from rotating freely. The locking collar 62 is sleeved on the outside of the connecting collar 61, and a spiral groove is formed on the inner wall of the locking collar 62. The limiting shaft 63 is threaded onto the outer wall of the connecting collar 61, and the outer wall of the limiting shaft 63 is slidably engaged with the spiral groove. When the locking collar 62 is rotated, under the action of the spiral groove and the limiting shaft 63, the locking collar 62 can move relative to the axis of the connecting collar 61, thereby causing the locking collar 62 and the connecting collar 61 to squeeze the first lens barrel 1 and the second lens barrel 2 respectively, thereby squeezing and braking the first lens barrel 1 and the second lens barrel 2. The outer wall of the locking collar 62 has a hole corresponding to the limiting shaft 63, so that the screwdriver can install or remove the limiting shaft 63 through the hole.

[0074] Furthermore, the locking assembly 6 also includes a first locking block 64, a first locking groove, a second locking block 65, and a second locking groove. The first locking block 64 is fixedly connected to the end of the connecting sleeve 31. The first locking groove is opened on one side of the connecting collar 61. The outer wall of the first locking block 64 is slidably engaged with the inner cavity of the first locking groove. The first locking block 64 can lock the connecting sleeve 31 onto the connecting collar 61. The second locking block 65 is fixedly connected to the side of the end of the connecting sleeve 31. The second locking groove is opened on one side of the second ear plate 33. The outer wall of the second locking block 65 is slidably engaged with the inner cavity of the second locking groove. Under the action of the second locking block 65, the connecting sleeve 31 can maintain a engaged state with the second ear plate 33, thereby preventing the connecting sleeve 31 from rotating relative to the second lens barrel 2. Under the action of the first locking block 64, the connecting collar 61 can be kept relatively stationary relative to the second lens barrel 2, thereby preventing the connecting collar 61 from rotating with the locking collar 62 when the locking collar 62 is rotated.

[0075] Example 2: Based on Example 1, the locking assembly 5 includes a mounting collar 51, a locking block 53, an annular groove 54, and an unlocking unit 55. The mounting collar 51 is fixedly sleeved inside the fixing cap 34. The mounting collar 51 is assembled inside the fixing cap 34 by internal bolts. The outer wall of the mounting collar 51 has a mounting hole 52. The locking block 53 is slidably sleeved inside the mounting hole 52. The annular groove 54 is opened at the end of the outer wall of the connecting shaft 41. The outer wall of the locking block 53 is slidably engaged with the inner cavity of the annular groove 54, that is, at least two locking blocks 53 are engaged with the connecting shaft 41. The connecting shaft 41 can be locked in the annular groove 54 at one end. Under the action of the fixing cap 34 and the limiting cap 42, the stability of the installation of the connecting sleeve 31 and the connecting shaft 41 can be ensured. The unlocking unit 55 is set inside the fixing cap 34. The unlocking unit 55 is used to adjust and limit the locking block 53. That is, the unlocking unit 55 can limit the locking block 53, so that the locking block 53 is in a stable state and engaged with the connecting shaft 41. The unlocking unit 55 can also drive the locking block 53 to slide and separate from the connecting shaft 41, thereby unlocking the connecting shaft 41.

[0076] Specifically, the unlocking unit 55 includes a connecting plate 551, a slot 552, a drive shaft 553, and a guide groove 554. The connecting plate 551 is disposed on the side of the locking block 53. The slot 552 is formed on the top of the mounting collar 51, and the inner cavity of the slot 552 communicates with the inner cavity of the mounting hole 52. The slot 552 is used for the installation of the connecting plate 551 and the drive shaft 553. The bottom of the outer wall of the connecting plate 551 is slidably sleeved inside the slot 552. One end of the drive shaft 553 is fixedly connected to the connecting plate 551. The guide groove 554 is formed on the side of the locking block 53, and the outer wall of the drive shaft 553 is slidably engaged with the inner cavity of the guide groove 554. The guide groove 554 formed on the outside of the locking block 53 is as follows: Figure 5 As shown, when the connecting plate 551 moves toward the locking block 53, the drive shaft 553 slides in the guide groove 554, thereby causing the locking block 53 to move toward the interior of the mounting hole 52, thus separating the locking block 53 from the connecting shaft 41. The side of the locking block 53 is provided with a sliding groove 555 that communicates with the guide groove 554. When the mounting collar 51 is not assembled inside the fixing cap 34, the connecting plate 551 is first inserted into the bottom of the cavity of the slot 552. At this time, the locking block 53 is inserted into the interior of the mounting hole 52 from the outside of the mounting collar 51, so that the locking block 53 connects with the drive shaft 553 through the sliding groove 555 until the drive shaft 553 slides into the interior of the guide groove 554, thus completing the assembly of the locking block 53.

[0077] Furthermore, the unlocking unit 55 also includes a sealing block 556, a fixing rod 557, a limiting spring 558, a support plate 559, a limiting block 5510, a support rod 5511, and a bearing collar 5513. The sealing block 556 is slidably sleeved inside the fixing cap 34. One end of the connecting plate 551 is fixedly connected to the sealing block 556, and one end of the fixing rod 557 is fixedly connected to the sealing block 556. The sealing block 556 is located inside the fixing cap 34, thereby reducing the compression of the sealing block 556 when carrying the first lens barrel 1 and the second lens barrel 2. Manually squeezing the sealing block 556 will allow it to be released. Drive connecting plate 551 moves, thereby driving locking block 53 to move and unlock via drive shaft 553. Limiting spring 558 is slidably sleeved on the outside of fixed rod 557. One end of limiting spring 558 is pressed against sealing block 556. Under the action of limiting spring 558, sealing block 556 can provide elastic tension to connecting plate 551, thereby stably engaging drive shaft 553 on connecting plate 551 at the end opposite to slide groove 555 in the inner cavity of guide groove 554, thus ensuring the stability of locking block 53 engaging connecting shaft 41. Support plate 559 is slidably sleeved on fixed rod 557. Externally, the other end of the limiting spring 558 is pressed against the support plate 559. The limiting block 5510 is fixedly connected to the other end of the fixing rod 557. One end of the support rod 5511 is fixedly connected to the mounting collar 51. A through hole 5512 is opened on one side of the support plate 559. One end of the outer wall of the support rod 5511 is slidably sleeved with the through hole 5512. The bearing collar 5513 is fixedly sleeved on the outside of the support rod 5511. One side of the bearing collar 5513 is pressed against the support plate 559. Under the action of the support rod 5511 and the bearing collar 5513, the limiting spring 558 can be pressed against the support plate 559. The stability of the support also allows for the formation of a gap between the support plate 559 and the mounting collar 51 to allow the movement of the limiting block 5510. Furthermore, the locking block 53 can limit the connection plate 551 and the sealing block 556 via the drive shaft 553, preventing them from sliding directly out of the fixing cap 34 under the action of the limiting spring 558. After removing the mounting collar 51 and taking the locking block 53 out of the mounting hole 52, the locking block 53 can be separated from the drive shaft 553, allowing the connection plate 551, sealing block 556, support plate 559, limiting block 5510, and limiting spring 558 to be removed directly, thus facilitating disassembly and maintenance.

[0078] Another objective of this invention is to provide a method for using a binocular low-light telescope, comprising the following specific steps:

[0079] Step 1: When adjusting the distance between the first lens barrel 1 and the second lens barrel 2, first rotate the locking collar 62 so that the locking collar 62 and the connecting collar 61 no longer squeeze and lock the first lens barrel 1 and the second lens barrel 2. The first lens barrel 1 and the second lens barrel 2 rotate relative to the connecting collar 31, changing the distance between the first lens barrel 1 and the second lens barrel 2. After the distance between the first lens barrel 1 and the second lens barrel 2 is adjusted, rotate the locking collar 62 relative to the connecting collar 61. Under the action of the limiting shaft 63, the locking collar 62 moves relative to the axis of the connecting collar 61, so that the locking collar 62 and the connecting collar 61 lock and limit the first lens barrel 1 and the second lens barrel 2.

[0080] Step 2: When using the first lens barrel 1 and the second lens barrel 2 separately, first loosen the locking collar 62 and the connecting collar 61, squeeze the sealing block 556, and the sealing block 556 pushes the connecting plate 551 toward the inside of the mounting collar 51. The drive shaft 553 on the connecting plate 551 cooperates with the guide groove 554 on the locking block 53, driving the locking block 53 toward the inside of the mounting hole 52, so that the locking block 53 separates from the annular groove 54 on the connecting shaft 41. Then pull out the connecting shaft 41, and finally pull out the connecting sleeve 31. The first lens barrel 1 and the second lens barrel 2 can then be used separately. In this way, the first lens barrel 1 and the second lens barrel 2 can be directly separated by pressing and pulling, thereby improving the convenience of separating the first lens barrel 1 and the second lens barrel 2.

[0081] Step 3: When assembling the first lens barrel 1 and the second lens barrel 2, firstly, align the first ear plate 32 and the second ear plate 33 on the first lens barrel 1 and the second lens barrel 2. Then, place the locking collar 62 and the connecting collar 61 between the second collar 44 and the second ear plate 33. Next, insert the connecting sleeve 31 into the interior of the second ear plate 33 and the first ear plate 32, and make the first locking block 64 and the second locking block 65 on the connecting sleeve 31 engage with the connecting collar 61 and the second ear plate 33 respectively. Finally, press the sealing block 556. The locking block 53 is then placed in the retracted position. Finally, the connecting shaft 41 is inserted until the limiting cap 42 at one end of the connecting shaft 41 is in contact with the first collar 43. The sealing block 556 is then released. Under the action of the limiting spring 558, the sealing block 556 drives the connecting plate 551 to reset and move. The connecting plate 551 drives the locking block 53 to slide through the driving shaft 553, so that one end of the outer wall of the locking block 53 engages with the annular groove 54 on the outside of the connecting shaft 41, thus completing the assembly of the first lens barrel 1 and the second lens barrel 2.
