Description

Technical Field

[0001] This utility model relates to the field of astronomical observation equipment, and more specifically, it relates to a rapid locking device for astronomical telescopes. Background Technology

[0002] In astronomical observation, telescopes need to frequently adjust their azimuth angle to align with different celestial objects. The accuracy of the locking after adjustment and the efficiency of operation directly affect the quality of observation. Current technologies often use manual bolt tightening or friction pad compression to lock the telescope's azimuth angle, which presents the following problems:

[0003] The locking operation is cumbersome, requiring manual tightening of bolts or adjustment of knobs, which takes a long time and affects the tracking efficiency of fast-moving celestial bodies.

[0004] The locking force is difficult to control; if it is too loose, the telescope may shift during observation, while if it is too tight, the adjustment mechanism may be damaged.

[0005] The stability after locking is insufficient, and it is prone to slight loosening due to vibration or external force, which reduces the accuracy of observation.

[0006] High frictional resistance during adjustment and locking results in uneven rotation and affects the flexibility of directional angle adjustment.

[0007] Therefore, there is an urgent need for a device that can quickly lock and unlock, is easy to operate, and locks securely, in order to solve the above problems. Utility Model Content

[0008] The purpose of this invention is to provide a quick locking device for astronomical telescopes, enabling rapid locking and unlocking after the telescope's azimuth angle is adjusted, while ensuring locking stability, smooth adjustment, and convenient operation.

[0009] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a rapid locking device for an astronomical telescope, comprising an azimuth angle adjustment locking structure, wherein the azimuth angle adjustment locking structure comprises a horizontal support platform, a central column, a transverse turntable, a thrust bearing, and a plurality of electromagnet locking columns;

[0010] Both the horizontal support platform and the transverse turntable are annular columns. The horizontal support platform is fixedly sleeved on the outer bottom of the central column. The bottom end of the central column is fixedly connected to the top end of the telescope bracket. A limiting groove matching the transverse turntable is provided in the middle of the top surface of the horizontal support platform. The transverse turntable is movably sleeved on the outer side of the central column. The thrust bearing is located between the bottom surface of the transverse turntable and the bottom surface of the limiting groove. The horizontal support platform has several locking grooves at positions corresponding to the outer side of the transverse turntable. An electromagnet locking post is provided in each locking groove. A return spring is connected between the locking groove and the electromagnet locking post. The electromagnet locking post is equipped with an energizing switch. The transverse turntable is a magnetically attracted metal platform, while the horizontal support platform is a non-magnetically attracted platform.

[0011] As a preferred embodiment of this utility model, a limiting nut is also provided at the top of the central column, which is used to prevent the transverse turntable from dislodging from the top of the central column.

[0012] In a preferred embodiment of this invention, the upper ring portion of the thrust bearing is fixedly connected to the bottom surface of the transverse turntable, and the lower ring portion of the thrust bearing is fixedly connected to the horizontal bearing platform.

[0013] As a preferred embodiment of this utility model, the horizontal support platform is provided with a through hole at the end position corresponding to the locking groove.

[0014] In a preferred embodiment of this invention, one end of the electromagnet locking post is connected to a return spring, and the other end of the electromagnet locking post is an arc-shaped surface that matches the outer surface of the transverse turntable. The arc-shaped surface fits more closely to the outer surface of the transverse turntable, thus better locking the turntable and securing its azimuth angle.

[0015] As a preferred technical solution of this utility model, the electromagnet locking post has an anti-slip pad at one end of its arc-shaped surface.

[0016] As a preferred embodiment of this utility model, when the electromagnet locking pin is not energized, the reset spring pulls the electromagnet locking pin back into the locking groove by the reset force.

[0017] As a preferred embodiment of this utility model, the locking groove is centrally symmetrically arranged along the diameter direction of the central column.

[0018] In summary, this utility model has the following beneficial effects: It enables rapid locking and unlocking. The locking state is controlled by the switching on and off of an electromagnet, eliminating the need for manual bolt operation, resulting in a fast response and significantly improving adjustment efficiency during observation; It achieves a secure and stable lock, with the arc-shaped surface of the electromagnet locking pin closely fitting the outer surface of the transverse turntable, combined with anti-slip pads to increase friction, and the symmetrically distributed locking grooves ensure balanced force distribution, effectively preventing loosening; Adjustment is smooth and effortless, with the thrust bearing reducing frictional resistance during the rotation of the transverse turntable, making directional angle adjustment more flexible, especially suitable for high-precision fine-tuning; The structure is safe and reliable, with the limit nut preventing the transverse turntable from dislodging, and the perforated design taking into account both air pressure balance and circuit protection, extending the device's service life; Operation is convenient, controlled simply by turning on the power switch, requiring no professional skills and lowering the operational threshold for observers.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0024] like Figure 1-3 As shown, this utility model provides a rapid locking device for an astronomical telescope. The core structure is an azimuth angle adjustment locking structure, including a horizontal support platform 1, a central column 2, a transverse turntable 3, a thrust bearing 4, and several electromagnet locking columns 5. The connection and function of each component are as follows:

[0025] Basic bearing and rotation structure: Both the horizontal bearing platform 1 and the transverse turntable 3 are annular columns; the horizontal bearing platform 1 is fixedly sleeved on the bottom outer side of the central column 2, and the bottom end of the central column 2 is fixedly connected to the top end of the telescope bracket to form an integral support foundation.

[0026] The transverse turntable 3 is movably fitted on the outside of the central column 2 and can rotate around the central column 2 (to achieve direction angle adjustment); the top surface of the horizontal bearing platform 1 is provided with a limiting groove 6 that matches the transverse turntable 3.

[0027] The thrust bearing 4 is set between the bottom surface of the transverse turntable 3 and the bottom surface of the limiting groove 6. Its upper ring is fixedly connected to the bottom surface of the transverse turntable 3, and its lower ring is fixedly connected to the horizontal bearing platform 1. This can greatly reduce the frictional resistance when the transverse turntable 3 rotates, making the direction angle adjustment smoother.

[0028] Locking and unlocking control structure: The horizontal support platform 1 is provided with several locking grooves 7 on the outer side of the corresponding transverse turntable 3. The locking grooves 7 are symmetrically distributed along the diameter direction of the central column 2 to improve the force balance during locking.

[0029] The locking groove 7 is equipped with an electromagnet locking pin 5, one end of which is connected to the return spring 8. The other end of the return spring 8 is fixed to the inner wall of the locking groove 7, and the other end is an arc-shaped surface that matches the outer side of the transverse turntable 3 to ensure a tight fit. The arc-shaped surface is also equipped with an anti-slip pad 11, which can increase the friction during locking.

[0030] The electromagnet locking pin 5 is equipped with an energizing switch, and the transverse turntable 3 is a magnetically attractive metal platform, such as an iron alloy, while the horizontal support platform 1 is a non-magnetically attractive platform, such as an aluminum alloy. When energized, the electromagnet locking pin 5 generates magnetic force. At this time, the magnetic force between the electromagnet locking pin 5 and the transverse turntable 3 overcomes the spring tension, causing the arc-shaped surface to fit against the outer surface of the transverse turntable 3, thus achieving locking. When de-energized, the elastic force of the return spring 8 pulls the electromagnet locking pin 5 back into the locking groove 7, releasing the lock. It should be noted that, in order to avoid magnetic interference from the return spring 8 on the electromagnet locking pin 5, the electromagnet locking pin 5 can be designed with two different materials: one end is an electromagnetic metal, and the other end is a non-magnetic material. The non-magnetic material end is connected to the return spring 8.

[0031] Auxiliary limiting and functional structure: The top of the central column 2 is equipped with a limiting nut 9 to prevent the transverse turntable 3 from coming off the top of the central column 2, thereby improving structural safety.

[0032] The horizontal support platform 1 has a through hole 10 at the end of the locking groove 7. This hole is used to balance the air pressure in the locking groove 7 and prevent the electromagnet locking pin 5 from being resisted by air pressure when it moves. It also allows the wires connecting the electromagnet locking pin 5 to pass through. The wires run through the through hole 10 and inside the return spring 8 to avoid the wires being exposed and worn.

[0033] In practical applications, when it is necessary to adjust the telescope azimuth angle, disconnect the power supply to the electromagnet locking pin 5: at this time, the elastic force of the reset spring 8 pulls the electromagnet locking pin 5 back into the locking groove 7, the electromagnet locking pin 5 separates from the outer side of the transverse turntable 3, and the transverse turntable 3 can rotate freely around the central column 2. The thrust bearing 4 reduces rotational friction, making the adjustment smoother.

[0034] Once the direction angle is adjusted to the correct position, close the power switch: the electromagnet locking pin 5 is energized to generate magnetic force, attracting the magnetically attracted transverse turntable 3, while simultaneously overcoming the tension of the return spring 8, so that the arc-shaped surface of the electromagnet locking pin 5 is tightly attached to the outer side of the transverse turntable 3, and the anti-slip pad 11 further increases the friction, thus achieving a firm lock of the direction angle.

[0035] The limit nut 9 always restricts the axial displacement of the transverse turntable 3 to prevent it from coming off the top of the central column 2; the through hole 10 balances the air pressure in the locking groove 7 to ensure the smooth extension and retraction of the electromagnet locking column 5, while protecting the wires from wear.

[0036] This implementation method combines electromagnets with mechanical structures to achieve rapid and stable locking of the telescope's azimuth angle, significantly improving the efficiency and reliability of astronomical observation.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
