Description

Technical Field

[0001] This application relates to the field of astronomical telescope accessories technology, and in particular to a support frame for an astronomical telescope. Background Technology

[0002] The telescope support frame is primarily used to support the astronomical telescope. The frame is a triangular support, mainly consisting of a base and three support legs hinged to the base. A connecting column for mounting accessory trays is rotatably installed at the bottom of the base. The top of the connecting column has a threaded section that passes through the base and is located at the top of the base. The theodolite stage on the astronomical telescope is threadedly connected to the threaded section at the top of the connecting column, thus fixing the theodolite stage to the base. The astronomical telescope is then mounted on the theodolite stage.

[0003] In related technologies, the lower outer wall of the connecting column has a through hole. When the connecting column needs to be rotated to connect with the theodolite, a pin can be inserted into the through hole and then rotated. However, to ensure a more stable connection between the connecting column and the theodolite, installers usually apply considerable force when rotating the connecting column. Therefore, when disassembling, rotating the connecting column in the opposite direction using the pin to disconnect it from the theodolite requires significant force. Furthermore, the length of the pin makes it difficult to apply force, resulting in a laborious and inconvenient disassembly of the theodolite. Utility Model Content

[0004] To address at least one of the aforementioned problems, this application provides a support frame for an astronomical telescope.

[0005] This application provides a support frame for an astronomical telescope, which adopts the following technical solution:

[0006] A support frame for an astronomical telescope includes a base, multiple support legs, and a connecting column. The multiple support legs are arranged circumferentially around the base and are all hinged to the base to support the astronomical telescope. The connecting column is rotatably mounted in the middle of the base, with its bottom end located at the bottom of the base and its top end located at the top of the base for threaded connection with a theodolite. The outer wall of the portion of the connecting column below the base has a pin hole for a pin shaft to pass through, and two clamping planes for wrench gripping are also symmetrically provided on the outer wall of the portion of the connecting column below the base.

[0007] Optionally, the clamping plane is located on the outer wall of the bottom end of the connecting column.

[0008] Optionally, the pin hole is located above the clamping plane.

[0009] Optionally, the support frame for the astronomical telescope also includes an accessory tray located below the base for placing astronomical telescope accessories and supporting the plurality of support legs.

[0010] Optionally, the accessory tray is fitted and slidably mounted on the connecting column, and the connecting column is provided with a limiting component to limit the sliding of the accessory tray, the limiting component being located below the accessory tray.

[0011] Optionally, the limiting component includes an adjusting sleeve that is sleeved and slidable on the connecting post and a set screw installed on the adjusting sleeve to limit the adjusting sleeve.

[0012] Optionally, the limiting component further includes a fine-tuning sleeve, which is sleeved on the adjusting sleeve and threadedly connected to the adjusting sleeve.

[0013] Optionally, the top of the accessory tray is provided with a placement slot, and a partition plate is provided in the placement slot, forming multiple chambers through the partition plate.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] When the user cannot rotate the connecting column by inserting the pin into the pin hole, a wrench can be used to clamp the clamping surface and then rotate it, thereby increasing the length of the torque and making it easier to apply force to rotate the connecting column to complete the disassembly.

[0016] The accessories on the astronomical telescope can be temporarily stored in the accessory tray, and can be taken out directly from the accessory tray when in use, thus improving the convenience of replacing the accessories on the astronomical telescope. In addition, the accessory tray also plays a limiting role in the opening angle of the support legs, improving the stability after the support legs are opened to a certain angle.

[0017] The placement slot can be divided into multiple independent chambers by partitions, allowing users to place different astronomical telescope accessories into different chambers for categorized placement, making them more convenient to retrieve during use.

[0018] The limiting component allows the height of the accessory plate to be adjusted, ensuring that the accessory plate remains supported and limited even when the support legs are spread at different angles. In addition, when fine-tuning the height of the accessory plate is required, the user can rotate the fine-tuning sleeve to adjust the height of the accessory plate, which serves to make both coarse and fine adjustments.

[0023] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0024] This application discloses a support frame for an astronomical telescope. (Refer to...) Figure 1 and Figure 2 The telescope support frame includes a base 1, multiple support legs 2, a connecting column 3, and an accessory tray 4. The support legs 2 are arranged circumferentially around the base 1, and their tops are hinged to the circumferential sidewalls of the base 1 via hinge shafts to support the base 1. The connecting column 3 is rotatably mounted on the base 1, with its bottom end at the bottom of the base 1 and its top end at the top. The top end of the connecting column 3 has a threaded section for connecting to a latitude / longitude station to mount the latitude / longitude station onto the base 1, and the telescope is used to connect to the latitude / longitude station. The outer wall of the portion of the connecting column 3 located below the base 1 has two symmetrically arranged clamping surfaces 31 for wrench gripping. The accessory tray 4 is slidably mounted on the connecting column 3 for temporary storage of telescope accessories.

[0025] In this embodiment, three support legs 2 are preferably provided. The three support legs 2 are evenly spaced around the periphery of the base 1, and adjacent support legs 2 are arranged in a figure-eight pattern to form a stable support. The connecting column 3 is located in the middle of the base 1, that is, the part of the connecting column 3 below the base 1 is located between the three support legs 2, which facilitates the rotation of the connecting column 3 when the support legs 2 are open.

[0026] Reference Figure 1 and Figure 2 The clamping plane 31 is located on the outer wall near the bottom of the connecting column 3. The design of the clamping plane 31 makes it easy for the wrench to clamp the connecting column 3, and also makes it less likely for the wrench to slip when rotating after clamping the connecting column 3. This makes it easier to drive the connecting column 3 to rotate and disconnect the connecting column 3 from the latitude and longitude platform to achieve disassembly and storage.

[0027] The outer wall of the portion of the connecting column 3 located below the base 1 is provided with a pin hole 32 for a pin to pass through and rotate the connecting column 3. The pin hole 32 is located above the clamping plane 31, and the pin holes 32 and the clamping plane 31 are arranged at intervals, thus providing the user with two ways to rotate the connecting column 3. In another embodiment, the clamping plane 31 can be located in the middle of the connecting column 3, and the pin hole 32 can be located below the clamping plane 31. The specific situation can be determined according to the actual production conditions.

[0028] Reference Figure 1 and Figure 2 The accessory plate 4 is located below the base 1 and sleeved on the connecting column 3. The inner walls of the multiple support legs 2 after opening are all in contact with the accessory plate 4, thus the accessory plate 4 can provide support and limit the opening of the support legs 2. The outer wall of the accessory plate 4 is provided with a contact surface 41 that fits against the inner outer wall of the support legs 2. The contact surface 41 can increase the contact area between the accessory plate 4 and the support legs 2, and improve the stability of the accessory plate 4 in supporting the support legs 2 after opening.

[0029] The top of the accessory tray 4 has a placement slot 42, and multiple partition plates 43 are integrally formed inside the placement slot 42. The placement slot 42 is divided into multiple independent chambers by the multiple partition plates 43. Different accessories on the astronomical telescope can be placed in the corresponding chambers for classified placement, which makes it more convenient to retrieve the accessories when replacing them later.

[0030] Reference Figure 1 and Figure 2 The accessory disk 4 can slide along the axial direction of the connecting column 3, and the connecting column 3 is fitted with a limiting component 33 to limit the downward sliding of the accessory disk 4. Since the accessory disk 4 will automatically slide down under the action of gravity, the limiting component 33 is located below the accessory disk 4, thereby limiting the downward movement of the accessory disk 4.

[0031] Reference Figure 2 and Figure 3 The limiting component 33 includes an adjusting sleeve 331 and a fine-tuning sleeve 332. The adjusting sleeve 331 is sleeved on the connecting post 3 and slides on the connecting post 3 to adjust the movement of the accessory disk 4 over a large distance, that is, to perform coarse adjustment of the movement of the accessory disk 4. The fine-tuning sleeve 332 is sleeved on the adjusting sleeve 331 and is threadedly connected to the adjusting sleeve 331. The bottom surface of the accessory disk 4 abuts against the top surface of the fine-tuning sleeve 332. When a small adjustment of the position height of the accessory disk 4 is required, that is, to perform fine adjustment of the movement of the accessory disk 4, it is only necessary to rotate the fine-tuning sleeve 332 relative to the adjusting sleeve 331 and move it towards the base 1.

[0032] Reference Figure 2 and Figure 3The adjusting sleeve 331 has a threaded hole on its outer wall, which communicates with the interior of the adjusting sleeve 331. A set screw 333 is installed in the threaded hole, and the set screw 333 can abut against the outer wall of the connecting column 3. When it is necessary to slide the adjusting sleeve 331 to adjust the height of the accessory plate 4, a hex wrench is used to drive the set screw to rotate without abutting against the connecting column 3; after the position of the adjusting sleeve 331 is adjusted, a hex wrench is used to drive the set screw to rotate and abut against the connecting column 3 to achieve the limit position. The operation is simple and the adjustment is convenient.

[0033] The implementation principle of a support frame for an astronomical telescope according to this application embodiment is as follows: When the user cannot rotate the connecting column 3 by inserting the pin into the pin hole 32, a wrench can be used to clamp the clamping surface 31 and then rotate it. This increases the length of the torque, making it easier to apply force to rotate the connecting column 3 to complete the disassembly. The accessories on the astronomical telescope can be temporarily stored in the accessory tray 4, and can be taken out directly from the accessory tray 4 when in use. The contact surface 41 can increase the contact area between the accessory tray 4 and the support leg 2, improving the stability of the accessory tray 4 in supporting the support leg 2 after the opening angle.

[0034] The limiting component 33 allows the height of the accessory plate 4 to be adjusted, ensuring that the accessory plate 4 remains supported and limited even when the support leg 2 is opened at different angles. Furthermore, for coarse adjustments to the movement of the accessory plate 4, a hex wrench is used to rotate the set bolt without pressing it against the connecting column 3. When coarsely adjusting the movement of the accessory plate 4, the adjusting sleeve 331 remains stationary; only the fine-tuning sleeve 332 needs to be rotated relative to the adjusting sleeve 331 and moved towards the base 1.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
