All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1 to 9 , a mounting device for a surveillance camera, including a camera 1, a connecting arm 2 is fixedly installed on the lower end surface of the camera 1, a connecting seat 3 is fixedly installed on the rear end surface of the connecting arm 2, a base 4 is arranged behind the camera 1, a fixed column 5 is fixedly installed on the front end surface of the base 4, the fixed column 5 is arranged in a bolt shape, a threaded groove 6 is opened on the outer surface of the fixed column 5, a convenient installation mechanism is arranged in front of the base 4, the convenient installation mechanism includes an outer fixing member arranged outside the fixed column 5, the outer fixing member includes a turntable 7 screw-drivenly connected to the outer surface of the fixed column 5, a transmission groove 8 is opened on the front end surface of the turntable 7, a slide block 9 is slidably connected inside the transmission groove 8, a first slide rod 10 is slidably connected to the front end surface of the slide block 9, a first chute 11 is opened on the upper end surface of the fixed column 5, a second slide rod 12 is slidably connected inside the first chute 11, a connecting rod 13 is fixedly installed between the second slide rod 12 and the first slide rod 10, a notch 17 is opened inside the fixed column 5, a U-shaped frame 14 is arranged inside the notch 17, the U-shaped frame 14 is fixedly connected to the second slide rod 12, and a first insertion rod 15 is fixedly installed on one side of the U-shaped frame 14, and a first insertion slot 16 corresponding to the first insertion rod 15 is opened on the outer surface of the connecting seat 3.

[0033] When the camera 1 needs to be installed, first insert the connecting seat 3 into the fixing column 5. Then, twist the turntable 7. The turntable 7 is in screw drive connection with the fixing column 5 through the thread groove 6. Therefore, the turntable 7 will rotate and descend. The rotation of the turntable 7 drives the displacement of the slider 9 slidably connected inside the transmission groove 8 through the transmission groove 8 opened on the front end face. A first slide bar 10 is slidably connected to the slider 9. The first slide bar 10 is fixedly connected to a second slide bar 12 through a connecting rod 13. The second slide bar 12 is slidably connected to the first chute 11. Therefore, under the combined action of the first chute 11 and the transmission groove 8, the second slide bar 12 will be driven to displace inwards. The second slide bar 12 will carry the U-shaped frame 14 to displace. The first insertion rod 15 on the U-shaped frame 14 will be inserted into the inside of the first insertion slot 16. The three first insertion rods 15 are synchronously inserted into the first insertion slot 16 and cooperate with each other for preliminary fixation.

[0034] A clamping member is arranged inside the outer fixing member. The clamping member includes a fixing rod 18 fixedly installed inside the notch 17. A buckle 19 is rotatably connected to the outer surface of the fixing rod 18. Limit shafts 20 are fixedly installed on both sides of the buckle 19.

[0035] A limit groove 21 is opened on the inner wall of the notch 17. The limit shaft 20 extends into the inside of the limit groove 21 and is slidably connected to the limit groove 21. A second chute 38 is opened on the inner wall of the U-shaped frame 14. The limit shaft 20 is slidably connected to the second chute 38.

[0036] Both the outer fixing member and the clamping member are correspondingly provided with three groups and are arranged in a ring-shaped dispersion.

[0037] When the U-shaped frame 14 displaces, since the limit shaft 20 on the buckle 19 is slidably connected to the second chute 38 on the U-shaped frame 14, the buckle 19 will be displaced. And the limit shaft 20 is also slidably connected to the limit groove 21. Therefore, under the combined action of the limit groove 21 and the second chute 38, the buckle 19 deflects around the fixing rod 18. The three buckles 19 synchronously deflect and are clamped on the connecting seat 3 to perform secondary reinforcement on the connecting seat 3.

[0038] The convenient installation mechanism further includes an inner fixing member arranged inside the base 4. The inner fixing member includes an inner cavity 22 opened inside the base 4. A transmission rod 23 is arranged inside the inner cavity 22. The upper end of the transmission rod 23 extends to the upper side of the base 4.

[0039] A limit ring 39 is fixedly installed on the outer surface of the transmission rod 23. A spring 24 is fixedly installed between the limit ring 39 and the lower end face inside the inner cavity 22. A guiding cavity 25 is communicated with the lower side of the inner cavity 22. A shape memory alloy rod 26 is slidably connected inside the guiding cavity 25. One end of the shape memory alloy rod 26 extends into the inside of the inner cavity 22 and is fixedly connected to the transmission rod 23.

[0040] The outer surface of the fixed column 5 is provided with a storage cavity 27. The storage cavity 27 is in communication with the guiding cavity 25. A second inserting rod 28 is slidably connected inside the storage cavity 27. The other end of the shape memory alloy rod 26 extends into the storage cavity 27 and is fixedly connected to the second inserting rod 28. A second slot 29 is provided on the inner wall of the connecting seat 3.

[0041] When the turntable 7 rotates, it will gradually press down the transmission rod 23, causing the transmission rod 23 to slide down inside the inner cavity 22, thereby squeezing the shape memory alloy rod 26, and making the second inserting rod 28 at the other end of the shape memory alloy rod 26 extend out of the storage cavity 27 and insert into the second slot 29. When the fixed state is released, the turntable 7 releases the pressing state. Under the action of the spring 24, the shape memory alloy rod 26 and the transmission rod 23 will return to their original positions.

[0042] An airbag 30 is arranged inside the first chute 11. The airbag 30 is fixedly installed between the second sliding rod 12 and the inner wall of the first chute 11. A cavity 32 is provided inside the base 4. A telescopic tube 33 is arranged inside the cavity 32. A communicating tube 31 is provided for communicating between the telescopic tube 33 and the airbag 30. A hollow cavity 34 is provided inside the shape memory alloy rod 26. The telescopic tube 33 is in communication with the hollow cavity 34.

[0043] A sliding cavity 35 is provided inside the second inserting rod 28. Two sides inside the sliding cavity 35 are both slidably connected with third inserting rods 36. A third slot 37 is provided on the inner wall of the second slot 29. The sliding cavity 35 is in communication with the hollow cavity 34.

[0044] Both the inner fixing member and the anti - detachment member are correspondingly provided with three groups and are arranged in a circularly dispersed manner.

[0045] When the second sliding rod 12 slides inside the first chute 11, it will squeeze the airbag 30, discharge the gas inside the airbag 30 into the telescopic tube 33 through the communicating tube 31, and enter the sliding cavity 35 through the hollow cavity 34 communicated with the telescopic tube 33, push out the third inserting rods 36 on both sides of the sliding cavity 35, and insert them into the third slot 37, thereby achieving secondary limiting. The setting of the telescopic tube 33 can extend synchronously with the displacement of the shape memory alloy rod 26 to ensure the normal operation of the device.

[0046] In practical applications, the camera 1 often needs to be installed at a relatively high position, which not only involves the complexity and safety issues of high-altitude operations, but also poses challenges to installation efficiency and stability. Traditional installation methods are usually complex, time-consuming and laborious. Moreover, once the installation is improper, it may affect the monitoring effect and the service life of the device. In order to improve this situation, it is necessary to simplify the installation process and ensure the stability of the installation of the camera 1. Therefore, in this solution, a convenient installation mechanism is set up to simplify the installation process of the camera 1, and the camera 1 is firmly fixed by the self-locking property of the thread. The multi-directional plug-in and snap-fastener 19 installation methods are combined with each other, which not only simplifies the installation process, but also improves the stability of the device;

[0047] At the same time, in this solution, a anti-detachment component is set up to add an insurance for the device and prevent the device from falling during high-altitude operation, resulting in device damage.

[0048] Usage method:

[0049] When the camera 1 needs to be installed, first insert the connecting seat 3 into the fixing column 5, and then turn the turntable 7. The turntable 7 is connected to the fixing column 5 through the thread groove 6 in a screw drive manner. Therefore, the turntable 7 will rotate and descend. When the turntable 7 rotates, through the drive groove 8 opened on the front end face, the slider 9 slidably connected inside the drive groove 8 will be displaced. A first sliding rod 10 is slidably connected to the slider 9, and the slidably connected first sliding rod 10 can maintain the drive of the slider 9 when the turntable 7 moves up and down. The first sliding rod 10 is fixedly connected to the second sliding rod 12 through the connecting rod 13, and the second sliding rod 12 is slidably connected to the first chute 11. Therefore, under the combined action of the first chute 11 and the drive groove 8, the second sliding rod 12 will be driven to displace inwards, and the second sliding rod 12 will carry the U-shaped frame 14 to displace. The first inserting rod 15 on the U-shaped frame 14 will be inserted into the inside of the first inserting slot 16, and the three first inserting rods 15 are synchronously inserted into the first inserting slot 16 and cooperate with each other for preliminary fixation;

[0050] When the U-shaped frame 14 displaces, since the limiting shaft 20 on the snap-fastener 19 is slidably connected to the second chute 38 on the U-shaped frame 14, the snap-fastener 19 will be displaced. And the limiting shaft 20 is also slidably connected to the arc-shaped limiting groove 21. Therefore, under the combined action of the limiting groove 21 and the second chute 38, the snap-fastener 19 will deflect around the fixing rod 18, and the three snap-fasteners 19 will deflect synchronously and be clamped on the connecting seat 3 to perform secondary reinforcement on the connecting seat 3;

[0051] When the turntable 7 rotates, it will gradually press down the transmission rod 23, so that the transmission rod 23 slides down inside the inner cavity 22, and then squeezes the shape memory alloy rod 26, so that the second inserting rod 28 at the other end of the shape memory alloy rod 26 extends out of the storage cavity 27 and is inserted into the second inserting slot 29. When the fixed state is released, the turntable 7 releases the pressing state, and under the action of the spring 24, the shape memory alloy rod 26 and the transmission rod 23 will return to their original positions;

[0052] When the sliding rod two 12 slides inside the sliding groove one 11, it will squeeze the airbag 30, discharge the gas inside the airbag 30 into the telescopic tube 33 through the connecting pipe 31, and enter the sliding cavity 35 through the hollow cavity 34 communicated with the telescopic tube 33, push out the insertion rods three 36 on both sides of the sliding cavity 35, and insert them into the insertion slots three 37, thereby achieving secondary limiting. The setting of the telescopic tube 33 can extend synchronously with the displacement of the shape memory alloy rod 26 to ensure the normal operation of the device.

[0053] The above is only the preferred specific implementation manner of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
