[0002] With the development of radio communication technology, monitoring and direction finding equipment is becoming increasingly miniaturized and lightweight. Portable direction finding antennas are one example of miniaturized direction finding antennas. Typically, portable direction finding antennas are used with a tripod and are usually fixed with screws. The threaded connections require tools for assembly and disassembly, which is time-consuming and laborious, significantly reducing the efficiency and convenience of installation and removal. Summary of the Invention
[0003] The purpose of this invention is to provide a quick-release mechanism with precise positioning and locking functions, in order to solve the technical problems in the background art.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A quick-release mechanism with precise positioning and locking functions includes: a quick-release connector and a quick-release support. The quick-release support includes a quick-release support base with an open upper part and a connecting hole with a boss for limiting the connection. The quick-release connector has a connecting shaft with a groove for limiting the connection at its lower end. The quick-release support base and the quick-release connector are positioned by the shaft-hole cooperation. The quick-release connector has an opening and closing groove, and the quick-release support base has a through hole corresponding to the opening and closing groove. The quick-release support includes an opening and closing slot seat with a dustproof plate at its lower part. The opening and closing slot seat is disposed on the quick-release support base. A sliding locking unit is provided in the opening and closing slot seat, and the locking unit can move laterally along the dustproof plate via an opening and closing handle. When the locking unit swings forward, it extends into the opening and closing groove to lock the quick-release connector. When the locking unit swings backward, it disengages from the opening and closing groove to unlock the quick-release connector.
[0006] In some embodiments, the locking unit includes a locking block, a limiting insert, and a first spring. The limiting insert is rotatably mounted in the opening and closing slot seat via a knurled shaft. The first spring is installed between the tail of the limiting insert and the quick-release support. Specifically, the limiting insert is provided with a limiting hole, and the opening and closing slot seat is reserved with a limiting hole for limiting the first spring.
[0007] The locking block is slidably connected in the opening and closing slot seat. The front end of the locking block is provided with a locking block groove. The limiting insert rotates around the knurled shaft under the action of the first spring. The limiting insert is used to cooperate with the locking block groove to prevent the locking block from rebounding, thereby unlocking the quick-release connector.
[0008] The limiting insert has a convex surface that can press against the locking block groove when the quick-release mechanism is unlocked, preventing the locking block from springing back.
[0009] In some embodiments, the quick-release connector is provided with a first clearance groove, which is located below the opening and closing groove. An eccentric rotating block is rotatably connected to the limiting insert. The eccentric rotating block is provided with a round-headed spring pin for pressing the head of the eccentric rotating block downward. During the downward movement of the quick-release connector, the eccentric rotating block passes through the first clearance groove and engages with the opening and closing groove. A second spring is provided on the opening and closing slot seat at the tail of the locking block. The other end of the second spring engages with the locking block boss of the locking block. The locking block rebounds under the action of the second spring force, thereby locking the quick-release connector.
[0010] In some embodiments, the connecting hole of the quick-release bracket has the same radius as the connecting shaft of the quick-release connector, and the boss surface of the connecting hole of the quick-release bracket is in contact with and positioned by the groove surface of the connecting shaft of the quick-release connector.
[0011] In some embodiments, the locking block is provided with a threaded hole for threaded connection with the opening and closing handle.
[0012] In some embodiments, the limiting insert is provided with a limiting hole, and the opening and closing slot seat is reserved with a limiting hole for limiting the first spring.
[0013] In some embodiments, a second clearance groove is provided on the quick-release connector, and the second clearance groove is located above the opening and closing groove.

[0030] The following will combine Figures 1-7 This application provides a detailed description of a quick-release mechanism with precise positioning and locking functions, as illustrated in the embodiments of this application. It is worth noting that the following embodiments are merely illustrative of this application and do not constitute a limitation thereof.
[0031] Example 1:
[0032] See Figure 1-7 As shown, a quick-release mechanism with precise positioning and locking functions includes: a quick-release connector 1 and a quick-release support 2. The quick-release connector is generally cylindrical with partially milled grooves, and the quick-release support is generally cylindrical with partially milled protrusions. Precise positioning is achieved through hole-shaft cooperation, and the concave-convex structure prevents the quick-release connector and quick-release support from rotating.
[0033] The quick-release support 2 includes a quick-release support base 21, which has an open upper part and a connecting hole with a boss for limiting the connection. The quick-release connector 1 has a connecting shaft with a groove for limiting the connection at its lower end. The quick-release support base 21 and the quick-release connector 1 are positioned by the shaft and the quick-release support 2 are engaged. The connecting hole of the quick-release support 2 has the same radius as the connecting shaft of the quick-release connector 1. The boss surface of the quick-release support 2 is in contact with the groove surface of the quick-release connector 1 for positioning.
[0034] The quick-release connector 1 is provided with an opening and closing groove 11, and the quick-release support base 21 is provided with a through hole corresponding to the opening and closing groove 11; the quick-release support 2 includes an opening and closing slot seat 22, the lower part of the opening and closing slot seat 22 is provided with a dustproof plate 24, the opening and closing slot seat 22 is disposed on the quick-release support base 21, the opening and closing slot seat 22 is provided with a slidingly connected locking unit, and the locking unit can move laterally along the dustproof plate 24 through the opening and closing handle 39, the opening and closing slot seat 22 is disposed on the quick-release support base 21, and the locking block 37 is provided with a threaded hole 372, which is threadedly connected to the opening and closing handle 39. The opening and closing slot seat 22 is provided with a sliding locking unit, and the locking unit can move laterally via the opening and closing handle 39. When the locking unit swings forward, it extends into the opening and closing slot 11 to lock the quick-release connector 1. When the locking unit swings backward, it disengages from the opening and closing slot 11 to unlock the quick-release connector 1.
[0035] The locking unit includes a locking block 37, a limiting insert 36, and a first spring 35. The limiting insert 36 is rotatably mounted in the opening and closing slot seat 22 via a knurled shaft 34. The first spring 35 is installed between the tail of the limiting insert 36 and the quick-release support 2. Specifically, the limiting insert 36 is provided with a limiting hole 361, and the opening and closing slot seat 22 is reserved with a limiting hole 222 for limiting the first spring 35.
[0036] The locking block 37 is slidably connected in the opening and closing slot seat 22. The front end of the locking block 37 is provided with a locking block groove 371. The limiting insert 36 rotates around the knurled shaft 34 under the action of the first spring 35. The limiting insert 36 is used to cooperate with the locking block groove 371 to prevent the locking block 37 from rebounding, thereby unlocking the quick-release connector 1.
[0037] The quick-release connector 1 is provided with a first clearance groove 13, which is located below the opening and closing groove 11. An eccentric rotating block 32 is rotatably connected to the limiting insert 36. The eccentric rotating block 32 is provided with a round-headed spring pin for pressing the head of the eccentric rotating block 32 downward. In the unlocked state of the quick-release mechanism, to prevent the eccentric rotating block 32 from rotating excessively, which would cause the edge 111 of the opening and closing groove of the quick-release connector to fail to effectively press against the eccentric rotating block 32, a round-headed spring pin 31 is provided on the eccentric rotating block 32.
[0038] When the quick-release mechanism is locked, to prevent the eccentric rotating block 32 from rotating around the copper bushing 33 and the knurled shaft 34 and then jamming against the quick-release connector 1, a second clearance groove 12 is provided on the quick-release connector 1. The second clearance groove 12 is located above the opening and closing groove 11.
[0039] During the downward movement of the quick-release connector 1, the eccentric rotating block 32 passes through the first clearance groove 13 and then engages with the opening and closing groove. Specifically, after the eccentric rotating block 32 passes through the first clearance groove 13, it contacts the edge 111 of the opening and closing groove of the quick-release connector and presses down the eccentric rotating block 32. The eccentric rotating block 32 rotates around the copper bushing 33 and the knurled shaft 34, causing the limiting insert 36 to rotate counterclockwise. The locking block 37 rebounds under the elastic force of the second spring 38, thereby locking the quick-release connector 1.
[0040] A second spring 38 is provided on the opening and closing slot seat 22 at the tail of the locking block 37. Specifically, the opening and closing slot seat 22 is provided with a threaded hole 223 to install a guide shaft 23, which is used to limit the second spring 38.
[0041] The other end of the second spring 38 engages with the locking block boss 373 of the locking block 37. The locking block 37 rebounds under the elastic force of the second spring 38, thereby locking the quick-release connector 1.
[0042] When the eccentric rotating block rotates clockwise, it comes into close contact with the limiting insert; when the eccentric rotating block rotates counterclockwise, it can separate from the limiting insert. When the quick-release connector is inserted into the quick-release support, the eccentric rotating block passes through the first clearance groove and the opening groove of the quick-release connector. The upper edge of the opening groove presses down on the eccentric rotating block, causing it to rotate counterclockwise and driving the limiting insert to rotate counterclockwise, thus releasing the lateral movement constraint of the locking block. Under the action of the second spring force, the locking block moves laterally, and the quick-release mechanism forms a locked state.
[0043] The quick-release connector is provided with an opening and closing groove, and the quick-release support is provided with a locking block. When the operator moves the opening and closing handle, the opening and closing handle drives the locking block to move laterally along the dustproof plate guide groove. The locking block can move backward a distance of up to 7mm, which can realize that the locking block disengages from the opening and closing groove of the quick-release connector, thereby unlocking the quick-release connector.
[0044] The above description is merely a preferred embodiment of the present invention and is intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
