In accordance with an embodiment of the present invention, a docking station 100 for connecting to a bottom bracket of a stand for a video camera equipment is provided, wherein the bottom bracket is movably mounted on a bottom bracket mounting mechanism. As shown in fig. 1, the socket 100 includes a body 110, an operating mechanism, and two stopping mechanisms. Wherein the body 110 has an axial direction, a radial direction, an accommodating space, and two mounting portions. Each catch mechanism is mounted on a respective one of the mounting portions. Each of the stop mechanisms includes a stop member switchable between a radially expanded deployed state and a radially collapsed deployed state under the control of the operating mechanism. In the extended state the stop member contacts the bottom bracket mounting mechanism to stop the bottom bracket 10 from moving relative to the bottom bracket mounting mechanism, and in the collapsed state the stop member does not contact the bottom bracket 10 mounting mechanism to allow the mount 100 to move relative to the bottom bracket mounting mechanism.

In a specific example of this embodiment, as shown in fig. 1, the operating mechanism is a pressing mechanism and the stopper mechanism is a sliding mechanism. The pressing mechanism includes a button 160 and a first biasing mechanism. The first biasing mechanism may include a first elastic member 150 such as a coil spring, a belleville spring, or the like, disposed between a wall of the receiving space perpendicular to the axial direction and the push button 160. The button 160 is axially movably installed in the accommodating space along the body 110, and the button 160 has a pressed state axially moved toward the inside of the body 110 under the pressing and a natural state biased back to an initial position by the first biasing mechanism after the pressure is released. Each slide mechanism includes a slider 130 and a second biasing mechanism. The second biasing mechanism may include, for example, at least one second elastic member 120 disposed between the slider 130 and the body 110 in a direction parallel to the radial direction. The second elastic member 120 may be, for example, a coil spring, a belleville spring, or the like.

Here, the slider 130 is slidably mounted to a corresponding one of the mounting portions in a radial direction of the body 110. The slider 130 is configured to slide radially inwardly of the body 110 to a collapsed state with axial inward movement of the button 160 in a depressed state of the button 160 while compressing the second biasing mechanism, and to slide radially outwardly of the body 110 with axial outward movement of the button 160 in a natural state of the button 160 to return to an expanded state with at least an outer edge thereof beyond outer edges of the body 110 and the depressing mechanism.

Specifically, as shown in fig. 1 and 3 a-3 e, each slider 130 has a hole 132, such as a kidney-shaped hole. The button 160 has a bottom plate and a projection 161 axially projecting from the bottom plate and corresponding to the hole 132 of each slider 130. Each projection 161 is inserted into a corresponding hole 132 and is movable relative to the corresponding hole 132 in the radial and axial directions of the body 110. Each projection 161 and the corresponding hole 132 are provided on their respective surfaces on the radially inner side with a ramp 1611,133, respectively, inclined towards the radially inner side and towards the base plate, so as to enable a corresponding radial movement of each slider 130 as the push button 160 moves axially.

Although the figures show ramps 1611,133 disposed on respective surfaces of the boss 161 and respective bore 132 on radially inner sides thereof and inclined radially inwardly and toward the base plate, respectively, to effect respective radially inward sliding of each slider 130 with axially inward movement of the button 160 and simultaneous compression of the second biasing mechanism, and respective radially outward sliding with release of the second biasing mechanism with axially outward movement of said button 160. It is also contemplated that ramps 1611,133 may be provided on the respective surfaces of each projection 161 and respective hole 132 radially outward thereof and inclined respectively radially outward and toward the base plate to effect respective radially outward sliding of each slider 130 with the axially inward movement of the button 160 and simultaneous stretching of the second biasing mechanism, and respective radially inward sliding with the axially outward movement of the button 160 and retraction of the second biasing mechanism.

Further, although the drawing shows that the pressing mechanism is to realize the sliding of the slider 130 radially inward or outward by pressing the button 160 and to return to the original position by the second biasing mechanism after releasing the button 160, it is also conceivable that the button may be fixed at the pressed position by a suitable positioning mechanism after being pressed and return to the natural state after the positioning mechanism is released. The positioning mechanism may be any suitable mechanism in the art as long as it enables positioning and release of the button 160. For example, the positioning mechanism may be a mechanism that includes a first pin hole on the side wall of the body, a second pin hole on the button 160, and a pin that is insertably mounted in the first and second pin holes. Wherein the second pin hole is in coaxial communication with the first pin hole just after the button reaches the pressed position so that insertion of the pin secures the button 160 in the pressed position and when the pin is removed, the button 160 automatically returns to its natural state.

Preferably, in the present embodiment, as shown in fig. 2, the body 110 includes a first section and a second section that are axially spaced apart and an intermediate section that is connected between the first section and the second section. Each mounting portion is formed by part of the opposed surfaces of the first and second sections together with the respective side wall portion of the intermediate section. The accommodating space extends through the first section and the middle section and partially extends into the second section. The receiving space has a section extending to and communicating with each mounting portion so that each projection 161 can be inserted from the section into the hole 132 of the slider 130 on the corresponding mounting portion.

Preferably, as shown in fig. 4d, there are two mounting portions and two sliding mechanisms, respectively. The intermediate section is formed by two diametrically spaced legs 1131, 1132. The opposing surfaces of the two legs 1131,1132 facing the central axis of the body 110 form part of the side walls of the receiving space. The mounting portions are radially spaced on either side of the receiving space by two opposed legs 1131, 1132. Each slider 130 may further include two mounting grooves disposed at both ends of the hole 132, and two second elastic members, such as springs, have one ends respectively mounted in the two mounting grooves and the other ends respectively abutted against the supports 1131, 1132.

In order to prevent the sliding blocks 130 from swinging laterally during the radial sliding process, in this embodiment, the connecting seat 100 may further include, for example, two limit blocks 190, which are respectively disposed outside the respective supports 1131,1132 and extend to respective outer sides of the two sliding blocks 130, so that the two limit blocks 190 sandwich each sliding block 130, and effectively inhibit the sliding blocks 130 from swinging.

Preferably, in the present embodiment, a limiting structure for limiting the axial movement range of the button 160 in the body 110 is provided between the body 110 and the button 160. For example, as shown in fig. 4c, at least one groove 112 extending axially is provided on the sidewall of the body 110 located in the receiving space. The buttons 160 are provided with flanges 162 corresponding to the respective grooves 112. Each flange 162 is axially movably inserted into the groove 162 along the corresponding groove 112. Alternatively, the body 110 is provided with at least one inner rib on a sidewall located in the accommodating space, and the button 160 is provided with a groove corresponding to the respective inner rib, and each inner rib is axially movably inserted into the groove along the corresponding groove, thereby limiting the axial movement range of the button 160 along the accommodating space.

In order to allow the sliders 130 to automatically retract and retract in the direction opposite to the pressing direction of the button 160, it is preferable that each of the sliders 130 has an outer edge portion beyond the outer edges of the body 110 and the pressing mechanism in the unfolded state thereof, and the side of the outer edge portion facing the first section has a slope 137 inclined toward the radially inner side and toward the first section, as shown in fig. 3a, so as to allow automatic retraction when the slope 137 comes into contact with an obstacle.

As shown in fig. 2, the socket 100 of the present embodiment can also be used to connect a hook 170. The body 110 and the pressing mechanism are respectively provided with an axial through hole for the hook 170 to pass through, and the axial through hole of the body 110 is provided with a central thread 111 at a position of one end of the second section far away from the button 160 for screwing the hook 170.

Although the figures show the operating mechanism as a pressing mechanism, it is also contemplated that the operating mechanism may be other suitable mechanisms, such as a rotating mechanism that is configured to transition a stopping mechanism, such as a sliding mechanism, from an expanded/collapsed state to an opposite collapsed/expanded state by rotating the rotating mechanism between a first position and a second position. For example, the actuating element can also be a pivoting element which can be pivoted between a first position and a second position and which is designed such that, by pivoting it between the first position and the second position, the blocking element, for example a sliding element, is moved from a folded-out/folded-in position into an opposite folded-out/folded-out position. Furthermore, although the pressing mechanism is shown as being disposed at the bottom of the body 110 and moving along the axial direction of the body 110, it is also contemplated that the operating mechanism may be disposed at other locations of the body 110 and the moving direction may be different.

Further, while the stop mechanism is shown as a sliding mechanism, it is contemplated that the stop mechanism may be any suitable mechanism. For example, the stopping mechanism may be a swing mechanism or the like that can be switched between a folded state and an unfolded state under the operation of the operating mechanism, without departing from the scope of the present invention.

Fig. 4 shows an application of the docking station 100 of the present embodiment to a stand of a photographic apparatus. The stand for photographic equipment of this embodiment includes a central axle 10, a central axle mounting mechanism having an axially extending mounting channel, and at least one, e.g., three legs 50, supporting the central axle mounting mechanism. As shown in FIGS. 5a-5h, the lower inner wall of the bottom bracket 10 has a socket mounting sleeve matching with the outer shape and size of the second section of the body 110. The socket 100 is fitted over the socket mounting sleeve. The bottom bracket mounting mechanism includes a body housing 40 having an axially extending central through hole 41 and a support mechanism for supporting the bottom bracket 10 on the body housing 40. The support mechanism includes a cross mount 30 disposed on the body mount 40 coaxially with the body mount 40. The cross mount 30 has an axial through bore 34 communicating with the central through bore 41 and a sidewall defining the axial through bore 34.

The side wall is provided with a U-shaped cutout 33 that opens upward and a radial through hole 38 diametrically opposite the cutout 33. The axial through bore 34 and the central through bore 41 together constitute the mounting channel. The cutout 33 and the radial through hole 38 are shaped and sized to allow at least a portion of the bottom bracket 10 including the seat 100 in the collapsed state of the stopper such as the slider 130 to pass therethrough to achieve the transverse state of the horizontal support bottom bracket 10, and the radial through hole 38 is also shaped and sized to stop the seat 100 in the expanded state of the stopper such as the slider 130 from passing therethrough. The bottom shaft 10 is configured to be supported in its transverse position by the bottom of the cutout 33 and the bottom of the radial through hole 38.

In order to more firmly lock the bottom bracket axle 10 in its horizontal or vertical position, the support mechanism preferably further comprises a bottom bracket axle locking mechanism having a locked state for locking the bottom bracket axle 10 in its vertical or horizontal position and an unlocked state for unlocking the bottom bracket axle 10.

The support mechanism includes a transverse hub 20 that is removably mounted within an axial through-hole 34 of a transverse support 30. Two pairs of insertion matching structures which are opposite in radial direction are arranged between the transverse support 30 and the transverse hinge sleeve 20. The lateral hub 20 can rotate relative to the lateral support 30 about the two pairs of connection lines inserted into the mating structure. At least a part of the middle shaft 10 can be axially movably sleeved in the transverse hinge sleeve 20 relative to the transverse hinge sleeve 20 and rotates together with the transverse hinge sleeve 20 between a vertical state and a transverse state.

Two lugs 23 which are diametrically opposite are arranged on the outer wall of the transverse hinge sleeve 20. The inner wall of the transverse support 30 is provided with a groove 31 corresponding to the left lug 23 at a position corresponding to the left lug 23. The inner wall of the transverse support 30 is provided with a through hole at a position corresponding to the right lug 23, and an internal thread is arranged in the through hole. The bottom bracket locking mechanism includes a nut 36 threaded into the through-hole and a knob 39 having a threaded rod 391. The right protrusion 23 is inserted into the nut 36, and the screw 391 is inserted into the nut 36 opposite to the protrusion 23 and can be screwed inward and press the transverse hinge sleeve 20 radially inward during the rotation of the knob 39.

The lateral hinge sleeves 20 have spherical outer walls 22. The transverse support 30 has a spherical inner wall section 32 which is engaged with the spherical outer wall 22 of the transverse hinge sleeve 20, i.e. the transverse hinge sleeve 20 is engaged with the transverse support 30 through a spherical surface. The spherical outer wall 22 of the transverse hinge sleeve 20 is matched with the spherical inner wall 32 of the transverse support 30, and after the middle shaft 10 passes through the transverse hinge sleeve 20, the deformation range of the transverse hinge sleeve 20 is reduced to be insufficient to enable the spherical outer wall 22 of the transverse hinge sleeve 20 to be separated from the envelope of the spherical inner wall 32 of the transverse support 30, so that the purpose of limiting the up-and-down movement of the transverse hinge sleeve 20 is achieved.

The transverse support 30 further comprises a connecting section located below the supporting section and sleeved in the central through hole 41 of the body seat 40, and a middle section between the supporting section and the connecting section. The middle section is always above the body seat 40 when the transverse support 30 is connected with the body seat 40. The lower end of the central through hole 41 of the body seat 40 is provided with an annular groove whose lower end is opened. The connecting section is provided with a radial protruding structure which can be disassembled and fixedly connected with the connecting section and radially extends into the annular groove. The intermediate segment, the annular groove, and the radially projecting structure are configured such that a lower surface of the intermediate segment abuts against the body seat 40 and an upper surface of the radially projecting structure abuts against a bottom surface of the annular groove in a state where the cross support 30 is coupled with the body seat 40, thereby restricting relative axial movement between the cross support 30 and the body seat 40, but allowing relative rotation between the cross support 30 and the body seat 40.

Preferably, the radially protruding structure is a retainer ring 43 detachably screwed, for example, by screw threads, to the lower portion of the connection section from the inner lower end of the central through hole 41. For example, the retaining ring 43 includes an annular sidewall that is threadably coupled to the connecting segment and an annular base coupled to the annular sidewall, the annular base having an inner diameter greater than an inner diameter of the annular sidewall.

Fig. 5a shows a cross-sectional view of the stent of the present embodiment between the installation of the socket 100, wherein the socket installation sleeve 800 comprises an upper section 801 and a lower section 802 in a stepped shape, wherein the upper section 801 is provided with an internal thread for matching with the external thread on the body 110.

Fig. 5b shows the socket in the mounted state, with the button 160 in the natural state and the slider 130 in the unfolded state. The outer diameter of the outer edge portion of the slider 130 in the unfolded state is larger than the outer diameter of the bottom bracket 10.

Fig. 5c shows the situation when the bottom bracket 10 is pulled to the lower end of the transversal support 30, where the push button 160 is in the natural state and the slide is in the unfolded state. It can be seen that the slide 130 passes smoothly through the larger inner diameter retaining ring 43, but is stopped by the lower bottom surface of the small inner diameter transverse support 30 so that the bottom bracket 10 cannot move further axially upward.

FIG. 5d shows the slider 130 collapsed to an outer diameter smaller than the inner diameter of the lower end of the cross support 30 and into the cross support 30 in the depressed state of the button 160.

Fig. 5e shows the transverse hinge sleeve 20 rotated 90 °, with the entire socket 100 in the axial through hole 34, and with the button 160 still pressed and the slider 130 in the closed position.

Fig. 5f shows the adapter 100 in the natural state of the button 160 and the sliding block 130 in the expanded state, in which the adapter 100 is still in the axial through hole 34, and the outer diameter of the sliding block in the expanded state is larger than the inner diameter of the radial through hole 38 and cannot pass through the radial through hole 38 out of the transverse support 30.

Fig. 5g shows that under the pressing action of the inner wall of the radial through hole 38 on the sliding block 130, the sliding block 130 is automatically contracted to the closed state with the help of the inclined surface 137, and then can enter the radial through hole 38. Of course, it is also possible to retract the slider 130 by pressing the button 160 without departing from the scope of the present invention.

Fig. 5h shows the sliding block 130 automatically returning to its expanded position after it has passed out through the radial through hole 38, which completes the transverse positioning of the bottom bracket.
