It is worth noting that the following embodiments are only used to explain the present application and do not constitute a limitation on the present application.

[0026] Embodiment 1:

[0027] See also Figure 1-Figure 2 , an automatic locking and fixing mechanism for a direction-finding antenna mounting tripod, comprising: an antenna adapter 1, a tripod flange 2, and a lock body 4 unit, wherein the antenna adapter 1 is used to connect the antenna; the tripod flange 2 is provided with a mounting sleeve, the antenna adapter 1 is installed in the mounting sleeve, and the lock body 4 unit is connected to the tripod flange 2, and is used to lock or unlock the antenna adapter 1 and the tripod flange 2.

[0028] In some embodiments, the lower portion of the antenna adapter 1 is adapted to the shape of the mounting sleeve, and a first locking hole is provided at the lower portion of the antenna adapter 1, and a second locking hole is provided at a position corresponding to the first locking hole on the tripod flange 2, and the first locking hole and the second locking hole cooperate with the lock body 4 unit to achieve locking or unlocking of the antenna adapter 1 and the tripod flange 2. Here, locking of the antenna adapter 1 and the tripod flange 2 refers to fixing the antenna adapter 1 and the tripod flange 2; and unlocking here refers to removing the antenna adapter 1 from the tripod flange 2.

[0029] In some embodiments, the lock body 4 unit includes a mounting box, which is disposed on the tripod flange 2. A limit telescopic unit and a trigger unit are disposed in the mounting box. The limit telescopic unit is used to limit the antenna adapter 1, and the trigger unit is used to lock or unlock the limit telescopic unit. The mounting box includes a lock cover 3 and a lock body 4 matched with the lock cover 3. A guide cavity for adapting the limit telescopic unit and an L-shaped mounting cavity for adapting the trigger unit are disposed in the lock body 4.

[0030] In some embodiments, the trigger unit includes a trigger section and a locking section, the trigger section includes an unlocking pin head 7, a rotating shaft 8, and an unlocking link 9, the unlocking link 9 is slidably arranged on the long side of the L-shaped installation cavity, the unlocking pin head 7 is connected to one end of the unlocking link 9 through the rotating shaft 8, a first spring 10 is sleeved on the unlocking link 9, one end of the first spring 10 is limited by the unlocking link 9, the other end of the first spring 10 is blocked by the blocking side wall formed by the long side of the L-shaped installation cavity protruding inward, and a limiting boss is provided on the unlocking pin head 7 on the side of the blocking side wall away from the first spring 10, and an open retaining ring 13 is provided between the limiting boss and the blocking side wall; when the unlocking link 9 moves toward the locking section, the locking section will move to the side away from the limiting telescopic unit to unlock the limiting telescopic unit. There is a evasive space above the long side of the L-shaped installation cavity, so the unlocking pin head 7 can only rotate upward through the rotating shaft 8, and cannot rotate downward due to the long side of the L-shaped installation cavity blocking below.

[0031] The locking section includes: a locking pin 6 and a second spring 11, the locking pin 6 is slidably arranged on the short side of the L-shaped installation cavity, and the second spring 11 is arranged at the end of the locking pin 6; the locking pin 6 and the unlocking link 9 have a guiding inclined surface at their mating ends; the end of the guiding inclined surface of the locking pin 6 is used to limit the position of the limiting telescopic unit. The limiting telescopic unit includes a locking slider 5 and a third spring 12, the locking slider 5 is slidably arranged in the guide cavity, one end of the third spring 12 is connected to the end of the locking slider 5, and the other end of the third spring 12 is connected to the side wall of the guide cavity, a boss that matches the locking pin 6 is provided on the side wall of the locking slider 5, a buckle is provided at the lower part of the locking slider 5, the buckle passes through the lock body 4, and an escape space is provided on the lock body 4 at a position that matches the buckle.

[0032] The trigger section further comprises a spring pin 14, which is arranged above the unlocking link 9 and is used for rebounding the unlocking pin head 7 flipped upward to a horizontal position.

[0033] In the entire automatic locking and fixing mechanism, the antenna adapter 1 is connected to the direction-finding antenna, and the remaining components are connected to the tripod via the tripod flange 2. The unlocking pin head 7 forms a rotating mechanism with the unlocking connecting rod 9 via the rotating shaft 8.

[0034] This mechanism mainly solves the problem of achieving fast and automatic locking when the direction-finding antenna is installed on a tripod. During the installation process, you only need to put the adapter at the bottom of the direction-finding antenna into the top flange of the tripod to lock it; when removing it, you only need to pull the handle to one side and then let go to unlock it, and you can take out the device with both hands; when installing it again, you don’t need to reset any mechanism and can proceed according to the original installation method, making the entire installation process fast and simple.

[0035] Installation process: Align the first locking hole of the antenna adapter 1 at the bottom of the direction-finding antenna with the second locking hole on the upper part of the tripod flange 2 and then insert it. At this time, the front end of the locking slider 5 is inserted into the first locking hole above the antenna adapter 1 to achieve automatic locking and fixation.

[0036] During this process, the bottom of the antenna adapter 1 first touches the unlocking pin head 7, and uses the device's own gravity to generate a gravity component through the 45° inclined surface of the contact surface to drive the unlocking pin head 7 to push the unlocking link 9 a certain distance into the structure; the head of the unlocking link 9 contacts the inclined surface of the locking pin 6, pushing the locking pin 6 to one side. At this time, the locking slider 5 is separated from the control of the locking pin 6 and moves forward under the elastic force of the second spring 11, so that the front end of the locking slider 5 is inserted into the first locking hole on the antenna adapter 1 and locked. After locking, the unlocking pin head 7 and the unlocking link 9 return to their original positions through the rebound force of the first spring 10. Ensure that the mechanism is restored to its original state and continue the next locking process.

[0037] Disassembly process: Simply pull the lower end of the locking slider 5 back and release it when you hear a metal collision sound. The device can then be removed.

[0038] During this process, the lower end of the locking slider 5 is pulled back. At this time, the locking pin 6 is subjected to the rebound force of the third spring 12 and moves toward the locking slider 5. The head of the locking pin 6 is inserted into the boss side of the side of the locking slider 5, and the locking slider 5 is fixed to unlock the device. In the process of removing the device, the first locking hole of the antenna adapter 1 touches the inclined surface of the head of the unlocking pin head 7. Due to the restriction of the rotating shaft 8 and the long side of the L-shaped installation cavity, the unlocking pin head 7 will rotate in the opposite direction of the antenna adapter 1 and exit its travel range, ensuring that the antenna adapter 1 will not be stuck. After the antenna adapter 1 is disengaged, the unlocking pin head 7 is subjected to the rebound force of the spring pin 14 and returns to the horizontal position, ensuring that the mechanism is restored as before to continue the next locking process.

[0039] Compared with the traditional solution, the advantages of this utility model are:

[0040] The automatic locking mechanism of the tripod for mounting the direction-finding antenna is quick and easy to operate, avoiding the cumbersome locking operation process that may cause the user to forget a step and thus create a safety hazard. The automatic locking mechanism is made of stainless steel, which is wear-resistant and has high strength. It can withstand heavy direction-finding antenna equipment and meet the requirements of quick disassembly and assembly with both hands. The structure is also corrosion-resistant and aging-resistant, and can be used for a long time in the field.

[0041] The above description is only a preferred embodiment of the present invention and is used to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
