[0028] See Figure 1 and Figure 2 or see Figure 3 and Figure 4, A quick locking device of the present utility model includes: a first connecting member 100, a mounting slot hole 110 arranged in the vertical direction is provided in the middle of the first connecting member 100, and a movable channel 120 communicating with the mounting slot hole 110 is provided through the side of the first connecting member 100; a second connecting member 200, the second connecting member 200 has a mounting part 210 that can be detachably inserted into the mounting slot hole 110; a movable member 300, which is movably arranged in the movable channel 120 and can extend into the mounting slot hole 110 to combine with the mounting part 210 to prevent the mounting part 210 from detaching from the mounting slot hole 110, or retract into the movable channel 120 to separate from the mounting part 210 to allow the mounting part 210 to detach from the mounting slot hole 110; a locking member 400, which is movably arranged outside the first connecting member 100 and can be fixed after moving up and down relative to the first connecting member 100. The locking member 400 is provided with a first engaging portion and a second engaging portion arranged in sequence in the vertical direction. The first engaging portion contacts the movable member 300 to drive the movable member 300 to extend into the mounting slot hole 110, and the second engaging portion contacts the movable member 300 to allow the movable member 300 to retract into the movable channel 120.

[0029] One of the first connecting member 100 and the second connecting member 200 is connected to an external device, and the other is used to fix or connect a bracket. See Figure 3 In an embodiment, the first connecting member 100 is used to connect a bracket, and the second connecting member 200 is used to connect an external device; see Figure 1 In an embodiment, the first connecting member 100 is connected to a pipe fitting, and this pipe fitting is used to hoist an external device, while the second connecting member 200 is directly used for fixed installation on the ceiling. Of course, according to actual usage needs, the first connecting member 100 and the second connecting member 200 can be respectively connected to different objects.

[0030] Among them, when assembling an external device to this quick locking device, the mounting part 210 is inserted into the mounting slot hole 110 in the vertical direction, and then the locking member 400 is driven to rise or fall to use the first engaging portion to drive the movable member 300 to extend into the mounting slot hole 110 to combine with the mounting part 210 to prevent the mounting part 210 from detaching from the mounting slot hole 110, thereby realizing quick assembly, and the external device will not fall off when tilted to improve the stability of assembly. When disassembling the external device, the locking member 400 is moved up and down until the second engaging portion can be contacted by the movable member 300. At this time, the movable member 300 can retract into the movable channel 120 and completely leave the mounting slot hole 110, and the mounting part 210 can be pulled out, so that the first connecting member 100 and the second connecting member 200 are completely separated.

[0031] See Figure 1 and Figure 2, or refer to Figure 3 and Figure 4 , in some embodiments of the present invention, the locking member 400 is threadedly connected to the first connecting member 100 and sleeved on the outer periphery of the first connecting member 100. An annular driving slope 410 is formed on the inner wall of the locking member 400. The driving slope 410 inclines outward away from the first connecting member 100 in the vertical direction. The part of the driving slope 410 close to the first connecting member 100 constitutes the first engaging portion. The movable member 300 is connected with a spring member 310 that elastically abuts against the driving slope 410. It can be understood that when the locking member 400 rotates relative to the first connecting member 100 through a threaded structure and then moves up and down and is fixed, at this time, the movable member 300 can be kept in cooperation with the first engaging portion or the second engaging portion. Taking Figure 1 as an example, the driving slope 410 is inclined upward and away from the first connecting member 100. At this time, the vicinity of the lower end of the driving slope 410 constitutes the first engaging portion. When the locking member 400 rises until the lower part of the driving slope 410 abuts against one end of the movable member 300, the spring member 310 is compressed, and the other end of the movable member 300 is pushed to extend out of the movable channel 120 to enter the mounting slot 110, so that the movable member 300 is combined with the mounting member 210. As the locking member 400 moves downward, one end of the movable member 300 moves upward along the driving slope 410, the spring member 310 recovers its elastic deformation, and the other end of the movable member 300 can gradually leave the mounting slot 110 and retract into the movable channel 120. It should be noted that in some embodiments, the part of the driving slope 410 away from the first connecting member 100 constitutes the second engaging portion. As Figure 1 shown, that is, when the movable member 300 abuts against the vicinity of the upper end of the driving slope 410, the movable member 300 can leave the mounting slot 110 and retract into the movable channel 120.

[0032] Of course, in other embodiments, the way for the locking member 400 to move up and down relative to the first connecting member 100 and then be fixed is not limited to the threaded connection way. For example: a structure combining a ratchet and a ratchet rack can also be adopted. The ratchet rack is arranged on the outer wall of the first connecting member 100 in the vertical direction, and the ratchet is arranged on the locking member 400 through an elastic member so as to be elastically engaged in the tooth groove of the ratchet rack.

[0033] Refer to Figure 1 and Figure 2 , or refer to Figure 3 and Figure 4, in some embodiments of the present utility model, the end of the driving slope 410 away from the first connecting member 100 is smoothly and transitionally connected with a relief groove 420, and the relief groove 420 constitutes the second engaging portion. It can be understood that when the movable member 300 moves from the end of the driving slope 410 close to the first connecting member 100 to the end of the driving slope 410 away from the mounting slot hole 110, as Figure 1 shown in the embodiment, one end of the movable member 300 enters the relief groove 420 after moving from the low slope of the driving slope 410 to the high slope. Under the action of the spring member 310, one end of the movable member 300 is stably located in the relief groove 420, avoiding jamming when the mounting member 210 on the second connecting member 200 is withdrawn.

[0034] See Figure 1 and Figure 2 , in some embodiments of the present utility model, the outer peripheral surface of the first connecting member 100 is a threaded post portion, the locking member 400 is a threaded sleeve matching the threaded post portion, and the inner peripheral wall of the threaded sleeve is recessed inward to form the frustum-shaped driving slope 410. The above structure is highly compact, realizing the threaded connection between the locking member 400 and the first connecting member 100 and the setting of the driving slope 410 with a minimalist structure. When the locking member 400 is provided with a relief groove 420, the relief groove 420 is also recessed inward from the inner peripheral wall of the threaded sleeve. For example, the relief groove 420 and the driving slope 410 can be directly obtained by injection molding or machining. It should be noted that the relief groove 420 is also annular, so that when the locking member 400 rotates to any angular position, one end of the movable member 300 can contact the driving slope 410 or the relief groove 420.

[0035] See Figure 1 and Figure 2, in some embodiments of the present utility model, a blocking and detaching head 220 having a cross-sectional shape consistent with that of the mounting slot hole 110 is provided at an end of the mounting member 210 away from the second connecting member 200. A stepped portion 230 is formed between the mounting member 210 and the blocking and detaching head 220. When the stepped portion 230 moves to face the movable channel 120, the second connecting member 200 abuts against the first connecting member 100, and both ends of the movable member 300 can respectively abut against the driving slope 410 and the stepped portion 230. It should be noted that when the mounting member 210 is inserted along the mounting slot hole 110, the blocking and detaching head 220 slides along the inner peripheral wall of the mounting slot hole 110. When the stepped portion 230 moves to face the movable channel 120, the user rotates the locking member 400 so that the driving slope 410 abuts against one end of the movable member 300. When the other end of the movable member 300 extends to the stepped portion 230, the movable member 300 forms a block on the blocking and detaching head 220, thereby preventing the mounting member 210 from being withdrawn from the mounting slot hole 110, thus completing the assembly between the first connecting member 100 and the second connecting member 200, which is beneficial to simplifying the structure of the mounting member 210.

[0036] See Figure 3 and Figure 4 , in some embodiments of the present utility model, in order to reduce the production and processing difficulty, the outer peripheral surface of the first connecting member 100 is a first cylindrical surface, the locking member 400 is a circular sleeve matching the first cylindrical surface, a frustum-shaped driving slope 410 is formed by the inward depression of the inner peripheral wall of the circular sleeve, a vertically extending screw rod 500 is fixedly connected to the central position of the first connecting member 100, and a threaded through hole 430 matching the screw rod 500 is provided at the central position of the circular sleeve. That is, when the circular sleeve rotates around the rod direction of the screw rod 500, the threaded through hole 430 moves up and down relative to the screw rod 500, thereby realizing the up and down movement of the circular sleeve relative to the first connecting member 100.

[0037] See Figure 3 and Figure 4 , in some embodiments of the present utility model, the mounting slot hole 110 is a circular sink or an annular sink, the mounting member 210 has a second cylindrical surface in contact with the inner peripheral wall of the mounting slot hole 110, thereby realizing the function of the second connecting member 200 rotating relative to the first connecting member 100, which is applicable to the use scenario of a photographic tripod head and realizes the function of panoramic photography of a camera or a video camera. An annular groove 211 is formed by the radial depression of the second cylindrical surface. The movable member 300 is composed of two steel balls sliding along the movable channel 120. The spring member 310 abuts between the two steel balls. The first engaging portion contacts one of the steel balls to press the other steel ball to keep abutting against the annular groove 211. It can be understood that Figure 3Taking the embodiment as an example, when the lower part of the driving ramp 410 contacts one of the steel balls, the two steel balls are completely pressed against each other, and the other steel ball rests in the annular groove 211; when the upper end of the driving ramp 410 or the yield groove 420 contacts one of the steel balls, there is a movable gap between the two steel balls. At this time, the mounting component 210 is directly pulled out, and the other steel ball moves in the direction of the compression spring member 310 to retract into the movable channel 120.

[0038] See also Figure 3 and Figure 4 In some embodiments of the utility model, the first connecting member 100 is provided with a flange portion 130 along the middle protrusion of the mounting slot hole 110, so that the mounting slot hole 110 becomes a circular groove. At the same time, in order to achieve a more compact structure, a mounting hole facing the threaded through hole 430 is provided in the middle of the flange portion 130, and one end of the screw rod 500 is fixedly connected in the mounting hole.

[0039] See also Figure 1 or Figure 3 In some embodiments of the present invention, the movable member 300 has a spherical surface in contact with the driving ramp 410. It should be noted that when the lock member 400 rotates relative to the first connecting member 100, the driving ramp 410 rotates and moves up and down relative to the movable member 300. The position where the movable member 300 contacts the driving ramp 410 is a spherical surface, which can avoid jamming and make the movable member 300 move more smoothly.

[0040] The utility model also discloses an imaging device, comprising the quick locking device described in any one of the above technical solutions; the imaging device can be quickly assembled with external equipment, and the assembled external equipment is not easy to fall off when tilted, so as to improve the stability of the assembly.

[0041] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments 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.

[0042] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
