[0023] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6This utility model provides a technical solution: a quick-release base, including a quick-release plate 1 connected to a camera, wherein the quick-release plate 1 is provided with a mounting base 2 detachably connected thereto, and the mounting base 2 is provided with a self-locking device for locking the quick-release plate 1, wherein the self-locking device includes a locking block 20 for locking the quick-release plate 1, and an internal inclined block 21 for pushing the locking block 20 to limit the quick-release plate 1. The mounting base 2 is also provided with a pin 22 that can unlock the internal inclined block 21 so that the internal inclined block 21 can push the locking block 20 to limit the quick-release plate 1, wherein the mounting base 2 is provided with a limiting groove 23 that cooperates with the limiting of the quick-release plate 1. The pin 22 is installed at the bottom of the limiting groove 23. A first limiting hole is provided at the bottom of the limiting groove 23. The pin 22 is installed in the first limiting hole and slides with the first limiting hole. When the quick-release plate 1 is not installed in the limiting groove 23, the pin 22 protrudes from the bottom surface of the limiting groove 23. When the quick-release plate 1 is installed in the limiting groove 23, the quick-release plate 1 will press down the pin 22. Inside the first limiting hole, there is also a ball 24 that slides with it. The ball 24 is located at the bottom end of the pin 22 and abuts against the bottom end of the pin 22. When the pin 22 is pressed down, it will simultaneously drive the ball 24 to be pressed down.

[0025] A base plate 3 is also provided at the bottom of the mounting base 2. A receiving cavity 4 for installing the internal inclined block 21 is provided between the mounting base 2 and the base plate 3. The internal inclined block 21 has a second limiting hole 210 corresponding to the first limiting hole. A first spring 25 is provided between the first limiting hole and the second limiting hole 210. That is, when the first spring 25 is in its uncompressed state, the first spring 25 passes through the first limiting hole and the second limiting hole 210 respectively. The two ends of the first spring 25 also abut against the ball 24 and the base plate 3 respectively. Abutment portions 213 are provided on both sides of one end of the internal inclined block 21. The abutment portions 213 are connected to the receiving cavity 4. A second spring 42 is connected between the side walls. When the first spring 25 is not compressed, it passes through the first limiting hole and the second limiting hole 210 respectively. The second spring 42 is compressed by the internal inclined block 21. Since the two ends of the first spring 25 pass through the first limiting hole and the second limiting hole 210 respectively, the first spring 25 effectively blocks the internal inclined block 21, preventing the compressed second spring 42 from being pushed by its elastic force. The internal inclined block 21 is also provided with a pushing part 214. When the second spring 42 pushes the internal inclined block 21, the pushing part of the internal inclined block 21... 214 can push the locking block 20 to limit the quick-release plate 1. In order to prevent the first spring 25 from blocking the internal inclined block 21 and to allow the second spring 42 to return and push the internal inclined block 21, when the quick-release plate 1 is installed in the limiting groove 23, the pin 22 will be pressed down. The pin 22 will press the ball 24 down into the second limiting hole 210 on the internal inclined block 21. Since the two ends of the first spring 25 are respectively in contact with the ball 24 and the base plate 3, when the first spring 25 is compressed into the second limiting hole 210, it is equivalent to the first spring 25 being completely compressed into the second limiting hole 210. Within 10, the first spring 25 no longer obstructs the internal inclined block 21. At this time, the internal inclined block 21, which is no longer obstructed by the first spring 25, is pushed back by the second spring 42 until the pushing part 214 of the internal inclined block 21 pushes the locking block 20 to limit the locking block 20 against the quick-release plate 1. Due to the elastic force of the second spring 42, the pushing part 214 of the internal inclined block 21 is equivalent to pressing against the locking block 20, thereby preventing the locking block 20 from falling off and not limiting the quick-release plate 1. This is equivalent to locking the locking block 20 against the quick-release plate 1, thereby completing the installation of the quick-release plate 1 on the mounting base 2.

[0026] In order to control the internal inclined block 21 to be guided and pushed by the second spring 42, the receiving cavity 4 is also provided with a first locking post 40 and a second locking post 41. The internal inclined block 21 is provided with a third limiting hole 211 and a first limiting groove 21223. The third limiting hole 211 is an elliptical hole. The third limiting hole 211 and the first locking post 40 are in a limiting sliding fit. The second locking post 41 and the first limiting groove 21223 are in a limiting sliding fit. The third limiting hole 211 is used to restrict the internal inclined block 21 from sliding. When the second locking post 41 and the first limiting groove 21223 are abutted, they are used to position the internal inclined block 21 so that the first limiting hole and the second limiting hole 210 are aligned.

[0027] The mounting base 2 is also equipped with an unlocking device that slides with it. This unlocking device can push the internal inclined block 21 so that the internal inclined block 21 does not block the locking block 20, thereby opening the locking block 20 and removing the quick-release plate 1. The unlocking device includes an unlocking block 26 that slides with the mounting base 2. The mounting base 2 is provided with a sliding groove 27. The unlocking block 26 and the sliding groove 27 are in a limited sliding engagement. The unlocking block 26 is provided with a connecting block 260. The connecting block 260 is provided with a third spring 261 that engages with it at one end. The other end of the third spring 261 abuts against the inner wall of the sliding groove 27. By providing the third spring 261, when the unlocking block 26 is pressed and the third spring 261 is compressed, the third spring 261 will return to its original position and push the unlocking block 26 back to its original position. Since the unlocking block 26 is installed on both sides of the mounting base 2, in order to push the internal inclined block 21 backward when the unlocking block 26 is pressed, the unlocking block 26 is provided with a first inclined surface 262 on the side corresponding to the internal inclined block 21, and the internal inclined block 21 is provided with a second inclined surface 215 corresponding to the first inclined surface 262. Therefore, when the unlocking block 26 is pressed on both sides at the same time, it is equivalent to compressing the third spring 261 and making the first inclined surface 262 contact with the second inclined surface 215 and generate a push. Therefore, when the unlocking block 26 is pressed, the push of the unlocking block 26 on the internal inclined block 21 is equivalent to the push of the first inclined surface 262 on the second inclined surface 215, thereby causing the internal inclined block 21 to retract and the pushing part 214 to separate from the locking block 20. In this way, the locking block 20 can be opened and the quick-release plate 1 can be taken out.

[0028] The self-locking device also includes a connecting rod 28 connected to the mounting base 2. A torsion spring 280 is provided on the connecting rod 28. The locking block 20 is rotatably connected to the connecting rod 28. The connecting rod 28 passes through both sides of the locking block 20 to achieve the connection with the locking block 20. The torsion spring 280 is installed on the connecting rod 28 and located between the two sides of the locking block 20. The two ends of the torsion spring 280 abut against the inner side of the locking block 20 and the mounting base 2, respectively. When the internal inclined block 21 pushes the locking block 20 to limit the quick-release plate 1, the locking block 20 is in a state of compressing the two ends of the torsion spring 280. Therefore, when the internal inclined block 21 retracts and separates from the locking block 20, the force of the torsion spring 280 returning to its original position can spring the locking block 20 open. When the internal inclined block 21 retracts and the first limiting hole 210 aligns with the second limiting hole 210, the compressed first spring 25 will push the ball 24 upward, causing the ball 24 to push back into the first limiting hole. The two ends of the first spring 25 will also pass through the first limiting hole and the second limiting hole 210 again, which means that the first spring 25 will block the internal inclined block 21 again. At this time, the second spring 42 is in a compressed state. When the first spring 25 pushes the ball 24 upward into the first limiting hole, it will generate an upward thrust on the pin 22, causing the pin 22 to protrude from the bottom surface of the limiting groove 23, thereby pushing the quick-release plate 1 out of the limiting groove 23, and thus completing the disassembly of the quick-release plate 1 on the mounting base 2.

[0029] Therefore, to prevent accidental pressing of the unlocking block 26 during use, which would cause the quick-release plate 1 to pop out, a safety lever 282 is also provided on the connecting rod 28 for limiting and sliding cooperation. The safety lever 282 has slotted holes 283 on both sides, with the slotted holes 283 and the connecting rod 28 having a limiting and sliding cooperation. A locking block 20 is located between the safety lever 282 and the mounting base 2. When the safety lever 282 is moved downwards along the connecting rod 28 so that the connecting rod 28 is at the uppermost end of the slotted hole 283, the safety lever 282 is locked. When the locking block 20 is in a wrapped state and the bottom end of the safety lever 282 is in contact with the base plate 3, even if the unlocking block 26 is accidentally pressed and the internal inclined block 21 is separated from the locking block 20, because the bottom end of the safety lever 282 is in contact with the base plate 3 and the safety lever 282 wraps around the locking block 20, the rebound force of the torsion spring 280 cannot push the locking block 20 to rotate away from the quick-release plate 1. Therefore, even if the unlocking block 26 is accidentally pressed, the locking block 20 will still limit and lock the quick-release plate 1.

[0030] In order to better limit the locking block 20 to the quick-release plate 1, an inclined plate 10 is provided on the side of the quick-release plate 1, and a limiting block 29 is provided on one side of the mounting base 2. When the quick-release plate 1 is installed in the limiting groove 23, the inclined plate 10 and the limiting block 29 are in a limiting fit, and when the locking block 20 locks the quick-release plate 1, the upper end of the locking block 20 is in a limiting fit with the inclined plate 10.

[0031] The working principle of this utility model is as follows: When it is necessary to install the quick-release plate 1 on the mounting base 2, the quick-release plate 1 is installed into the limiting groove 23, so that the quick-release plate 1 presses down the pin 22. The pin 22 presses the ball 24 from the first limiting hole to the second limiting hole 210. At this time, the first spring 25 does not obstruct the internal inclined block 21, so the compressed second spring 42 pushes the internal inclined block 21 forward, so that the internal inclined block 21 pushes the locking block 20 to limit the quick-release plate 1, thereby completing the installation of the quick-release plate 1 on the mounting base 2, and then completing the installation of the camera on the mounting base 2. When it is necessary to remove the camera from the mounting base 2, the safety lever 282 is pushed upward. This causes the safety lever 282 to unlock the locking block 20. Then, pressing the unlocking block 26 causes the first inclined surface 262 on the unlocking block 26 to push the second inclined surface 215 on the inner inclined block 21, thereby pushing the inner inclined block 21 to separate from the locking block 20. At this time, the force of the torsion spring 280 returning to its original position pushes the locking block 20 to separate from the quick-release plate 1. When the inner inclined block 21 retracts, the first spring 25 pushes the ball 24 upward again into the first limit hole, causing the pin 22 to push upward, thereby pushing the quick-release plate 1 out, thus completing the removal of the camera from the mounting base 2. The entire installation and removal process is quick and simple, which can greatly simplify the installation and removal process and save corresponding working time.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
