Description

Technical Field

[0001] The utility model relates to the technical field of loading and unloading mechanical structures, and more specifically, to a quick-release structure for a stabilizer. Background Art

[0002] In the existing stabilizers, the quick-release plate is assembled by pushing it into the base along the dovetail groove from the back to the front or from the front to the back. This sliding installation method cannot smoothly install the quick-release plate and its load to the marked position at one time. When the quick-release plate is already loaded, the increased weight will increase the sliding resistance of the quick-release plate relative to the base, which will increase the difficulty of sliding. In addition, when switching between horizontal and vertical shooting or when the stabilizer head is relatively compact, this sliding quick-release plate requires a large space for assembly and disassembly, resulting in increased difficulty in loading and unloading. In addition, the existing quick-release plate is locked or unlocked relative to the base by a locking member, specifically, the locking member is driven to move horizontally or vertically to open or lock one side of the quick-release plate. This locking method is difficult to apply to the use scenarios of switching between horizontal and vertical shooting or the scenario of a compact stabilizer head. Utility Model Content

[0033] Embodiment 1

[0034] like Figures 1 to 7 The first embodiment of the quick-release structure for a stabilizer of the utility model is shown. The quick-release structure of this embodiment is used for loading and unloading between a quick-release plate 200 and a base 100, and the base 100 is provided with an installation space 110 for slidingly installing the quick-release plate 200. Specifically, dovetail blocks 210 are provided on both sides of the quick-release plate 200, and dovetail grooves 111 that cooperate with the dovetail blocks 210 are provided on both sides of the installation space 110. The existing installation method of the quick-release plate 200 and the base 100 is: push and install it into the base 100 from back to front or from front to back along the dovetail groove 111. This sliding installation method requires a larger installation space 110, which cannot meet the needs of scenes such as switching between horizontal and vertical shooting or a relatively compact stabilizer head.

[0035] The quick-release structure includes a locking block 300 and a first driving member. In order to rotatably install the locking block 300 inside the base 100, a mounting groove 120 is provided in the base 100 of this embodiment, and a notch 130 is provided in the base 100 to connect the mounting groove 120 with the mounting space 110. Specifically, the locking block 300 is rotatably installed in the mounting groove 120, the first driving member is installed between the locking block 300 and the base 100, and the driving force of the first driving member drives the locking block 300 to rotate and switch from the unlocking position to the locking position, and the locking block 300 is provided with a clamp 310 that can cooperate with the inner side wall of the base 100 to form the mounting space 110. In the locked position, the clamp 310 cooperates with the inner side wall on the opposite side of the base 100 to form a dovetail groove 111 that cooperates with the dovetail blocks 210 on both sides of the quick-release plate 200, so that the quick-release plate 200 is clamped. Figures 1 to 4 In the unlocked position, the upper part of the locking block 300 is hidden inside the base 100 , and when the quick-release plate 200 enters the installation space 110 vertically from top to bottom, the locking block 300 does not produce any resistance to the entry of the quick-release plate 200 .

[0036] The locking block 300 is specifically rotatably connected to the base 100 via a rotating shaft 320. The locking block 300 is a cylindrical structure as a whole, and the axis of the rotating shaft 320 coincides with the axis of the cylindrical structure. Of course, when the base 100 has inconsistent thicknesses in the same width direction, the rotating shaft 320 of this embodiment can also be set to a variable diameter structure, such as Figures 5 to 7 As shown. The rotating shaft 320 is arranged on both sides of the end of the locking block 300, which can effectively ensure the rotation stability of the locking block 300. In order to facilitate the installation and removal of the locking block 300, one end of the installation groove 120 is set as a closed end, and the other end is set as an open end connected to the outside. The open end is closed by the first cover plate 140. The first cover plate 140 is detachably connected to the base 100, and the outer surface of the first cover plate 140 is flush with the side surface of the base 100 after the first cover plate 140 is covered. Figure 1 , Figure 3 shown.

[0037] In addition, the quick release structure of this embodiment further includes a first locking member for keeping the locking block 300 in an unlocked position and a second locking member for keeping the locking block 300 in a locked position, and both the first locking member and the second locking member are disposed between the locking block 300 and the base 100. The first locking member can keep the locking block 300 in an unlocked position, facilitating the quick assembly of the quick release plate 200 and the base 100; the second locking member can keep the locking block 300 in a locked position, achieving stable assembly of the quick release plate 200 and the base 100, and preventing the quick release plate 200 and the base 100 from loosening during use of the base 100, so as to ensure the working stability of the stabilizer.

[0038] In this embodiment, the first driving member is a first elastic member 400, and the elastic force of the first elastic member 400 is used to drive the locking block 300 to rotate from the unlocking position to the locking position. Figure 1 , Figure 2 As shown. The first elastic member 400 is specifically a torsion spring, which is sleeved on the outer periphery of the rotating shaft 320 and one free end of the torsion spring abuts against the locking block 300, and the other free end of the torsion spring abuts against the base 100, specifically abuts against the first cover plate 140, and a mounting hole that matches the other free end of the torsion spring can be opened on the first cover plate 140. The elastic force of the torsion spring is used to realize the automatic switching from the unlocking position to the locking position, and the elastic force of the torsion spring can also help the locking block 300 to remain in the locking position. In order to achieve a compact structure, this embodiment opens a mounting cavity 350 for installing a torsion spring at the end of the locking block 300. This design can minimize the gap between the locking block 300 and the first cover plate 140.

[0039] The first locking member is a lever 500, which is connected to the outer periphery of the locking block 300. The base 100 is provided with a first through hole 150 which is connected to the mounting groove 120. The lever 500 is movably connected to the first through hole 150 and extends out of the base 100. The axis of the first through hole 150 is perpendicular to the axis of the locking block 300. Figure 1 , Figure 2 By turning the lever 500, the locking block 300 can be manually rotated, and the locking block 300 can be manually temporarily kept in the unlocked position or the locked position, or the unlocked position and the locked position can be switched manually. The lever 500 of this embodiment is mainly used to manually temporarily keep the locking block 300 in the unlocked position to facilitate the assembly of the quick-release plate 200 and the base 100.

[0040] When the lever 500 abuts against the inner wall at one end of the first through hole 150, specifically the inner wall at the bottom end of the first through hole 150, the locking block 300 is in the unlocked position; when the lever 500 abuts against the inner wall at the other end of the first through hole 150, specifically the inner wall at the top end of the first through hole 150, the locking block 300 is in the locked position. The lever 500 is limited by the inner walls at both ends of the first through hole 150, so that the lever 500 switches between the first position and the second position, which correspond to the locked position and the unlocked position of the locking block 300, respectively, and the operation is convenient. In the absence of external force, under the elastic force of the first elastic member 400, the locking pressure block 300 tends to rotate to or remain in the locking position, and the lever 500 abuts against the top of the first through hole 150; when the quick-release plate 200 needs to be installed, the lever 500 is manually pushed downward so that the lever 500 abuts against the bottom end of the first through hole 150. During the movement of the lever 500, the elastic force of the first elastic member 400 can be overcome, so that the locking pressure block 300 rotates to the unlocking position and remains in the unlocking position, so as to facilitate the installation of the quick-release plate 200.

[0041] The second locking member is a locking handle 600. A limiting groove 330 is provided on the outer periphery of the locking pressure block 300. The locking handle 600 is movably connected to the base 100 and the locking handle 600 can be moved to cooperate with the limiting groove 330. Figure 1 , Figure 2 Specifically, the locking handle 600 is threadedly connected to the base 100, and the locking handle 600 can be rotated to move closer to or farther from the limiting groove 330. When the locking handle 600 is rotated to abut against the limiting groove 330, the locking block 300 is kept in the locked position, preventing the locking block 300 from rotating back to the unlocked position when the quick-release plate 200 is locked, causing the quick-release plate 200 to loosen or fall off.

[0042] The quick-release structure for the stabilizer of the utility model is implemented according to the following steps:

[0043] Under the elastic force of the first elastic member 400 , the locking pressing block 300 is in a locking position, which is an initial position.

[0044] During installation, before installation, it is necessary to switch the position of the locking block 300 to the unlocked position, manually push the lever 500 downward, so that the lever 500 is against the bottom end of the first through hole 150. During the movement of the lever 500, the elastic force of the first elastic member 400 can be overcome, so that the locking block 300 is rotated to the unlocked position and maintained in the unlocked position. In the unlocked position, the quick-release plate 200 is installed on the base 100. After the quick-release plate 200 is installed, the lever 500 is released, and the first elastic member 40 0, the locking pressure block 300 rotates to the locking position, so that the locking pressure block 300 presses the quick-release plate 200; the locking handle 600 is rotated, and the locking handle 600 approaches the limiting groove 330. When the locking handle 600 is rotated to abut against the limiting groove 330, the locking pressure block 300 is kept in the locking position, preventing the locking pressure block 300 from rotating back to the unlocking position when the quick-release plate 200 is locked, causing the quick-release plate 200 to loosen or fall off, so as to ensure the working stability of the stabilizer.

[0045] When disassembling, first unlock the locking handle 600, then directly lift up the quick release plate 200, the inclined surface of the dovetail block 210 on the side of the quick release plate 200 will squeeze the locking block 300 to rotate it to the unlocked position, and then lift up the quick release plate 200 to complete the disassembly of the quick release plate 200.

[0046] Embodiment 2

[0047] The second embodiment of the quick-release structure for a stabilizer of the utility model is similar to the first embodiment, except that the first elastic member 400 is a compression spring, one end of which abuts against the inner wall of the mounting groove 120, and the other end of which abuts against the locking block 300. The elastic force of the compression spring is used to realize the automatic switching from the unlocking position to the locking position, and the elastic force of the compression spring can also help the locking block 300 to remain in the locking position.

[0048] Embodiment 3

[0049] The third embodiment of the quick-release structure for a stabilizer of the utility model is similar to the first embodiment, except that the setting of the first locking member of the present embodiment is different from the setting of the first locking member in the first or second embodiment. The first locking member of the present embodiment can automatically switch from the locking position to the unlocking position and remain in the unlocking position without manual operation.

[0050] Specifically, in this embodiment, the first locking member is a locking pin 700, and a pin hole 340 cooperating with the locking pin 700 is provided on the locking pressure block 300. The locking pin 700 is connected to a second driving member for driving the locking pin 700 to approach or move away from the pin hole 340. The second driving member is installed on the base 100, and the locking pin 700 extends into the locking hole to keep the locking pressure block 300 in the unlocked position. Figure 8The locking pin 700 extends into the pin hole 340 , and the locking block 300 is kept in the unlocked position, which facilitates the assembly of the quick-release plate 200 and the base 100 .

[0051] Among them, the second driving member is a lock pin pressing block 800, the lock pin pressing block 800 is movably connected to the base 100, the lock pin pressing block 800 is provided with a first inclined surface 810, the lock pin 700 includes a latch portion 710 matched with the pin hole 340 and a linkage portion 720 connected to the tail of the latch portion 710, the linkage portion 720 is provided with a second inclined surface 730 interacting with the first inclined surface 810, and the force of the first inclined surface 810 on the second inclined surface 730 includes a component force along the axial direction of the lock pin, such as Fig. 9 The initial state of the lock pin 700 is a state of being matched with the pin hole 340. At this time, the lock pin pressing block 800 partially protrudes from the base 100. When the quick-release plate 200 is installed on the base 100, the lock pin pressing block 800 is pressed down. Under the action of the first inclined surface 810 and the second inclined surface 730, the lock pin 700 withdraws from the pin hole 340, and the locking pressing block 300 rotates to the locking position under the driving action of the first driving member.

[0052] In addition, a second elastic member 820 is connected between the bottom of the locking pin pressing block 800 and the base 100, and a third elastic member 740 is connected between the side of the linkage portion 720 and the base 100. The central axis of the second elastic member 820 and the central axis of the third elastic member 740 are arranged vertically. The arrangement of the second elastic member 820 and the third elastic member 740 enables the locking pin pressing block 800 and the locking pin 700 to automatically return to their initial positions after the quick-release plate 200 is removed from the base 100. Fig. 9 A boss 830 is disposed on the top of the locking pin pressing block 800 . In the initial position, the boss 830 is higher than the bottom surface of the installation space 110 , and the upper surface of the locking pin pressing block 800 is flush with the bottom surface of the installation space 110 .

[0053] In order to adapt to the installation of the lock pin 700 and the lock pin pressing block 800, a receiving groove 160 for installing the lock pin 700 is provided in the base 100 in this embodiment, and a partition 170 is provided between the receiving groove 160 and the installation groove 120, and the partition 170 is provided with a second through hole for the lock pin 700 to pass through. The lock pin 700 and the lock pin pressing block 800 are both installed in the receiving groove 160 to ensure the regularity of the product structure and the beauty of the appearance. In order to facilitate the installation of the lock pin 700 and the lock pin pressing block 800, one end of the receiving groove 160 of this embodiment is set as a closed end and the other end is set as an open end connected to the outside world. The open end is closed by a second cover plate 180. The second cover plate 180 is detachably connected to the base 100, and the outer surface of the second cover plate 180 is flush with the side surface of the base 100 after the second cover plate 180 is covered. The second elastic member 820 is specifically disposed between the bottom side of the locking pin pressing block 800 and the bottom wall of the receiving groove 160 , and the third elastic member 740 is disposed between the side wall of the locking pin 700 and the inner wall of the second cover plate 180 .

[0054] The quick-release structure for the stabilizer of the utility model is implemented according to the following steps:

[0055] During installation, the quick-release plate 200 is installed on the base 100, and the top boss 830 of the locking pin pressing block 800 is pressed by the quick-release plate 200 to be flush with the upper surface of the base 100, that is, the bottom surface of the installation space 110. During the downward pressing process of the locking pin pressing block 800, under the action of the first inclined surface 810 and the second inclined surface 730, the locking pin 700 moves to the latch portion 710 to exit the pin hole 340, and the function of maintaining the unlocked position is released; the locking pressing block 300 is driven to rotate by the first elastic member 400 until it rotates to the locking position, and the clamping opening 310 and the dovetail groove 111 on the opposite side cooperate to clamp the quick-release plate 200. To prevent loosening, the locking handle 600 is rotated again and the locking handle 600 approaches the limiting groove 330. When the locking handle 600 is rotated to abut against the limiting groove 330, the locking pressure block 300 is kept in the locked position to prevent the locking pressure block 300 from rotating back to the unlocked position when the quick-release plate 200 is locked, causing the quick-release plate 200 to loosen or fall off, thereby ensuring the working stability of the stabilizer.

[0056] When disassembling, first unlock the locking handle 600, then directly lift up the quick-release plate 200, the inclined surface of the dovetail block 210 on the side of the quick-release plate 200 will squeeze the locking pressure block 300 to rotate it to the unlocked position, and then lift up the quick-release plate 200; in the unlocked position, the latch portion 710 is aligned with the pin hole 340. Since there is no pressure from the quick-release plate 200, the locking pin pressure block 800 also moves upward under the action of the second elastic member 820, and then the locking pin 700 leaves the squeezing of the locking pin pressure block 800 and moves toward the pin hole 340 under the action of the third elastic member 740 until the latch portion 710 is inserted into the pin hole 340, and the locking pressure block 300 is fixed in the unlocked position, waiting for the next installation of the locking quick-release plate 200.

[0057] Embodiment 4

[0058] This embodiment is the fourth embodiment of the quick-release structure for a stabilizer of the utility model. This embodiment is similar to the first embodiment, except that in this embodiment, the first locking member includes the locking pin 700 and the locking pin pressing block 800 in the third embodiment in addition to the lever 500 in the first embodiment. Specifically, in this embodiment, the first elastic member 400 and the locking pin 700 are respectively located on the left and right sides of the locking pressing block 300, and the first cover plate 140 and the second cover plate 180 are respectively located on the left and right sides of the base 100. Fig.10 shown.

[0059] The quick-release structure for the stabilizer of the utility model is implemented according to the following steps:

[0060] During installation, the quick-release plate 200 is installed on the base 100, and the top boss 830 of the locking pin pressing block 800 is pressed by the quick-release plate 200 to be flush with the upper surface of the base 100, that is, the bottom surface of the installation space 110. During the downward pressing process of the locking pin pressing block 800, under the action of the first inclined surface 810 and the second inclined surface 730, the locking pin 700 moves to the latch portion 710 to exit the pin hole 340, and the function of maintaining the unlocked position is released; the locking pressing block 300 is driven to rotate by the first elastic member 400 until it rotates to the locking position, and the clamping opening 310 and the dovetail groove 111 on the opposite side cooperate to clamp the quick-release plate 200. To prevent loosening, the locking handle 600 is rotated again and the locking handle 600 approaches the limiting groove 330. When the locking handle 600 is rotated to abut against the limiting groove 330, the locking pressure block 300 is kept in the locked position to prevent the locking pressure block 300 from rotating back to the unlocked position when the quick-release plate 200 is locked, causing the quick-release plate 200 to loosen or fall off, thereby ensuring the working stability of the stabilizer.

[0061] When disassembling, first unlock the handle of the locking block 300, then directly lift up the quick release plate 200, the inclined surface of the side rail of the quick release plate 200 will squeeze the locking block 300 to rotate it open, or after unlocking the handle of the locking block 300, manually move the lever 500 to drive the locking block 300 to the unlocked position, and then lift up the quick release plate 200. In the unlocked position, the latch portion 710 is aligned with the pin hole 340. Since there is no pressure from the quick release plate 200, the locking pin block 800 also moves upward under the action of the third elastic member 740, and then the locking pin 700 leaves the squeeze of the locking pin block 800 and moves toward the pin hole 340 under the action of the second elastic member 820 until the latch portion 710 is inserted into the pin hole 340, and the locking block 300 is fixed in the unlocked position, waiting for the next installation of the locking quick release plate 200.

[0062] Compared with Embodiments 1 to 3, this embodiment provides a variety of operation options for keeping the locking block 300 in the unlocked position, which can meet the operation requirements of different users.

In order to make the description concise, not all possible combinations of the above-mentioned technical features are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] Obviously, the above embodiments of the utility model are only examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here.
