Detailed Implementation

[0037] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 should fall within the protection scope of the present invention.

[0038] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, apparatus, product, or device that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

[0039] In one embodiment of this utility model, a quick-release locking device is provided, see [link to relevant documentation]. Figures 1 to 4 The quick-release locking device includes a mounting base body 1, a mounting member 2, and a quick-release assembly 3. The mounting base body 1 has a mounting groove, with a first inclined surface 11 on one side. The mounting member 2 has a second inclined surface 21 on one side and a step 22 on the other side. The quick-release assembly 3 is mounted on the mounting base body 1 and has a first state and a second state. The quick-release assembly 3 includes an extension 32. When the quick-release assembly 3 is in the first state, the extension 32 is engaged with the step 22, the second inclined surface 21 abuts against the first inclined surface 11, and the mounting member 2 is locked within the mounting groove. When the quick-release assembly 3 is in the second state, the extension 32 is not positioned above the step 22, and the mounting member 2 is detachable from the mounting groove.

[0040] Unlike common hand-tightening screw-in clamping and fixing devices in the prior art, the quick-release locking device provided by this utility model has a dovetail groove on the mounting base body 1, the mounting component 2 has a dovetail plate structure that cooperates with the dovetail groove, and a quick-release component 3 with a first state and a second state is provided on one side of the dovetail groove, which can realize a more reliable and durable quick-release and quick-locking structure.

[0041] In one embodiment of this utility model, such as Figure 4 As shown, the quick-release assembly 3 also includes an operating part 31, a rotating shaft 35, a torsion spring 36, a quick-lock device 38, and a quick-lock button 39.

[0042] The interconnected operating part 31 and the extension part 32 constitute the main structure of the quick-release assembly 3, and the left and right sides of the main structure are inverted U-shaped or Z-shaped. The operating part 31 is located at a position away from the mounting groove relative to the extension part 32. Preferably, the operating part 31 is located on the outside of the mounting base body 1 for operation. The extension part 32 extends to the location of the mounting groove, and the mounting base body 1 is provided with a cavity for the extension part 32 to pass through and accommodate the extension part 32. The operating part 31 is configured to rotate the extension part 32 relative to the mounting base body 1 to switch the quick-release assembly 3 from the first state / second state to the second state switching / first state.

[0043] The quick-release assembly 3 can optionally switch from the first state / second state to the second state / first state via the rotating shaft 35. Preferably, the rotating shaft 35 is fixedly connected to the extension 32 and rotatably connected to the mounting base body 1; or, the quick-release assembly 3 further includes a rotating shaft 35, which is rotatably connected to the extension 32 and fixedly connected to the mounting base body 1.

[0044] The extension 32 has a latch structure at one end near the mounting groove. The upper part 321 of the latch structure is located above the step 22, and the lower part 322 of the latch structure is located below the step 22. The rotating shaft 35 is connected to the lower part 322 of the latch structure.

[0045] A through groove 323 is provided at the middle position of the lower part of the latch structure. The rotating shaft 35 passes through the through groove 323, and the torsion spring 36 is disposed on the rotating shaft 35 and at the location of the through groove 323. The two arms of the torsion spring 36 extend towards the direction of the operating part 31, with one arm pressing against the lower surface of the extension 32 and the other arm pressing against the mounting base body 1. The torsion spring 36 is configured to apply a force to the extension 32 toward the step 22. Thus, when the operating part 31 is in a free state, under the pressure of the upper and lower arms of the torsion spring 36, the upper part 321 of the latch structure is engaged with the upper surface of the step 22. Under the pressure of the upper part 321 of the latch structure and the second inclined surface 21, the mounting member 2 is locked in the mounting groove of the mounting base body 1.

[0046] In this locked state, if a downward pressure is applied to the operating part 31, the latch structure rotates around the rotating shaft 35. Figure 3In the indicated direction, the latch structure rotates counterclockwise, thus opening the upper part 321 of the latch structure relative to the step 22, i.e., the upper part 321 of the latch structure is offset from directly above the step 22. At this time, the quick-release assembly 3 is in the second state, and the mounting piece 2 can be freely removed from the mounting groove of the mounting base body 1. It is evident that the quick-release locking device provided by this utility model is very convenient to disassemble and install.

[0047] In this structure, the operating part 31 is positioned away from the mounting groove relative to the extension 32, and the rotating shaft 35 is rotatably connected to the extension 32. Therefore, the force-applying arm is greater than the force-receiving arm, making it very easy to press the operating part 31 during assembly and disassembly, thus improving the user experience. Preferably, the operating part 31 is provided with anti-slip texture 312 to prevent slippage when pressure is applied to the operating part 31.

[0048] In one embodiment of this utility model, the mounting base body 1 is provided with a limiting groove 13; the quick-release assembly 3 also includes a quick-lock device 38 and a quick-lock button 39 connected to each other. Under the action of the quick-lock button 39, the quick-lock device 38 moves in a first direction and engages with the limiting groove 13, or the quick-lock device 38 moves in a second direction and exits the limiting groove 13, the second direction being opposite to the first direction; when the quick-lock device 38 engages with the limiting groove 13, the quick-release assembly 3 is in a locked state.

[0049] The quick-lock device 38 and quick-lock button 39 are disposed on the operating part 31, and the first direction is perpendicular to the rotation direction of the extension 32 relative to the mounting body 1. For example, in Figure 3 In this context, the first direction is horizontal and perpendicular to the cross-section. It should be noted that the quick-lock device 38 and quick-lock button 39 can specifically adopt a rebound mechanism structure or other movable button structures; this utility model does not impose specific limitations.

[0050] When the quick-release assembly 3 is in the first state, pressing the quick-lock button 39 pushes the quick-lock device 38 into the limiting groove 13. The upper surface of the quick-lock device 38 abuts against the upper inner wall of the limiting groove 13. At this time, if the operating part 31 is pressed, the quick-lock device 38 will prevent the extension part 32 from rotating relative to the mounting base body 1 under the pressure of the limiting groove 13, thereby locking / completely locking the mounting part 2 in the mounting groove of the mounting base body 1 and preventing the mounting part 2 from being unlocked due to accidental operation. When it is necessary to unlock the mounting part 2, first push the quick-lock button 39 to drive the quick-lock device 38 out of the limiting groove 13, and then press the operating part 31 so that the extension part 32 does not obstruct the step from exiting.

[0051] Preferably, the operating part 31 is further provided with a limiting hole 311, and the quick lock 38 is provided with a protruding structure near the limiting hole 311, the protruding structure being disposed within the limiting hole 311.

[0052] The quick-release locking device described in this utility model is configured as an astronomical quick-release locking device. The mounting base body 1 is configured to connect with the first astronomical device, and the mounting component 2 is configured to connect with the second astronomical device. The first astronomical device can be one of the following: a telescope mount, an equatorial mount, a detector, a thermostat, etc., and the second astronomical device can be another of the following: a telescope mount, an equatorial mount, a detector, a thermostat, etc.

[0053] The quick-release locking device proposed in this utility model has two states: locked state and free unlocking state. Even with repeated disassembly and assembly, the wear is small and there is no problem of spring deformation. It has good wear resistance, long service life, and simple and compact structure, light weight and low cost.

[0054] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0055] The above description is only a specific embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
