Description

Technical Field

[0001] This utility model relates to the technical field of live streaming shooting stands, and in particular to a live streaming shooting stand with a magnetic support structure system. Background Technology

[0002] In live streaming shooting scenarios, the stability and ease of storage of the bottom support system are core factors affecting the practicality of the shooting stand. Traditional live streaming shooting stands generally have many limitations in their support components: the support legs are not stable enough in contact with the ground, especially when used on hard surfaces such as smooth tabletops and tiles. They lack effective anti-slip structures and are prone to tilting or even tipping over due to slight collisions or shaking during operation, increasing the risk of equipment falling; the support components lack reliable limiting structures when folded, and the support legs are prone to free unfolding due to vibrations during transportation or movement, which not only takes up extra storage space but may also collide with other components and cause wear; some support legs use purely mechanical buckles to achieve angle limiting, and after long-term use, the buckles are prone to wear and tear, causing the limiting to fail, and the support angle will shift under force, affecting the overall stability of the shooting stand; in addition, the unfolding and folding operations of traditional support components mostly rely on manual alignment or complex buckles, and the operation steps are cumbersome, reducing the efficiency of equipment debugging before live streaming. Utility Model Content

[0003] In order to overcome the shortcomings and deficiencies of the existing technology, this utility model provides a live shooting stand with a magnetic structure support system, which solves the technical problems of the existing live shooting stand support system being complex in structure, inconvenient to open and close, and the purely mechanical opening and closing mechanism being easily worn down with repeated use, resulting in unstable support.

[0004] This utility model achieves the above-mentioned objectives through the following technical solution: a live streaming shooting stand with a magnetic structure support system, including a top angle adjustment and clamping system, a middle telescopic rod assembly, and a bottom support system. The bottom support system includes an upper fixed seat and a lower fixed seat, with a fixed base provided between the upper and lower fixed seats. The length of the upper fixed seat is not less than the length of the top angle adjustment and clamping system when it is retracted. The lower fixed seat includes a support assembly and a button assembly. The support assembly includes a support foot, a connecting rod, and a magnet. The magnet is located at the bottom of the support foot, and the connecting rod is made of iron.

[0005] Preferably, the button assembly includes a button base and a button connecting part, with a retractable push rod accommodated between the button base and the button connecting part.

[0006] Preferably, the button base has an inclined boss inside facing the lower fixing seat, and the cross-section of the inclined boss is smaller at the top and larger at the bottom.

[0007] Preferably, the retractable push rod is provided with a return spring in the receiving groove of the button connection part.

[0008] Preferably, the top angle adjustment and clamping system includes a mobile phone clamping module and a secondary handle, which are rotatably connected to the connecting platform via a first rotating connector and a second rotating connector, respectively.

[0009] Preferably, the secondary handle includes a fixed part and an extension part. The fixed part is rotatably connected to the connecting platform through the second rotating connector, and the extension part is slidably connected to the fixed part through a limiting structure.

[0010] Preferably, the mobile phone clamping module includes an openable and rotatable clamping part and a clamping support part; the clamping part rotates relative to the clamping support part via a rotating shaft, and is limited in its usage state after rotation by a limiting structure.

[0011] Preferably, the first rotating connector includes a first rotating connecting part disposed at the bottom of the clamping support and a first rotating seat protruding from the upper surface of the connecting platform. The first rotating connecting part is inserted into the groove in the middle of the first rotating seat and connected by a rotating shaft.

[0012] Preferably, the second rotating connector includes a second rotating connecting part disposed at the bottom of the fixed part and a grooved rotating seat disposed on the connecting platform, wherein the second rotating connecting part rotates relative to the grooved rotating seat via a rotating shaft.

[0013] Preferably, the upper end face of the connecting platform is provided with a large gear portion, and the second rotating connecting portion is provided with a small gear portion on the surface opposite to the large gear portion of the connecting platform.

[0014] Compared with the prior art, the beneficial effects obtained by this utility model are: A live streaming shooting stand with a magnetic support structure includes a top angle adjustment and clamping system, a middle telescopic rod assembly, and a bottom support system. The bottom support system includes an upper fixed seat and a lower fixed seat, with a fixed base disposed between the upper and lower fixed seats. The length of the upper fixed seat is not less than the length of the top angle adjustment and clamping system when it is retracted. The lower fixed seat includes a support assembly and a button assembly. The support assembly includes a support foot, a connecting rod, and a magnet. The magnet is disposed at the bottom of the support foot, and the connecting rod is made of iron. When the support assembly is folded up, the iron connecting rod and the magnet at the bottom of the support foot can quickly adhere and attach, achieving precise positioning and fixation of the support foot. This prevents the support foot from freely unfolding due to vibration during storage or transportation, significantly reducing storage space occupation. It also reduces the probability of collision and wear between components, extending the equipment's lifespan and solving the problems of easy wear and failure and unstable support angle of traditional purely mechanical limiting structures after long-term use. The magnetic adsorption characteristic makes the unfolding and folding operation of the support assembly more efficient. There's no need to manually align complex clips; simply push the support foot, and the magnetic force between the magnet and the iron connecting rod will quickly complete the positioning, reducing equipment debugging time before live streaming and solving the problem of inconvenient opening and closing of traditional support structures, thus improving the user experience. The magnetic force can be flexibly adjusted according to the contact surface material. When used on non-magnetic surfaces, the magnet at the bottom of the support foot itself acts as a counterweight to increase contact pressure, indirectly improving the anti-slip effect. When used on iron-containing surfaces, the magnetic force further enhances stability, increases friction between the shooting stand and the contact surface, and reduces the risk of tilting due to external collisions or operational shaking, making the shooting stand suitable for various live streaming scenarios such as desktops, floors, and outdoors.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. However, the described embodiments are only some embodiments of the present invention, and not all embodiments. The terms "left," "right," "large," and "small" in the embodiments are used to distinguish technical features and are not intended to limit the size and orientation of the technical features. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figures 1 to 8A live streaming shooting stand with a magnetic support system includes a top angle adjustment and clamping system, a middle telescopic rod assembly, and a bottom support system. The top angle adjustment and clamping system includes a mobile phone clamping module 1 and a secondary handle 2. The mobile phone clamping module 1 and the secondary handle 2 are rotatably connected to a connecting platform 5 via a first rotating connector 3 and a second rotating connector 4, respectively. The mobile phone clamping module 1 includes an openable and rotatable clamping part 11 and a clamping support part 12. The clamping arm of the clamping part 11 is an openable and rotatable structure, and the opening and closing of the clamping part 11 is driven by a spring or thread to adapt to the length and width of the mobile phone. The clamping part 11 rotates relative to the clamping support part 12 via a rotating shaft, and is limited in its working state after rotation by a limiting structure. The inner side of the clamping arm of the clamping part 11 has an anti-slip soft pad to avoid damaging the mobile phone and increase friction to prevent slippage.

[0027] The connecting platform 5 serves as a transition structure between the top angle adjustment and clamping system and the middle telescopic rod assembly, integrating a two-degree-of-freedom rotary joint. A large gear portion 53 is provided on the upper end face of the connecting platform 5. A rotating shaft bearing assembly is provided between the connecting platform 5 and the middle telescopic rod assembly. The connecting platform 5 can rotate 360° horizontally around the central axis of the middle telescopic rod assembly. Specifically, the connecting platform 5 includes an upper connecting platform and a lower connecting platform, which rotate relative to each other around a concentric axis. The upper connecting platform is fixedly connected to the top angle adjustment and clamping system, and the lower connecting platform is fixedly connected to the middle telescopic rod assembly. Because the upper and lower connecting platforms rotate relative to each other around a concentric axis, the relative horizontal rotation of the top angle adjustment and clamping system and the middle telescopic rod assembly is achieved. Furthermore, a large gear portion 53 is provided on the outer end face of both the upper and lower connecting platforms, meshing with a small gear portion 2111 to achieve a fixed horizontal rotation angle.

[0028] The first rotating connector 3 includes a first rotating connector 31 disposed at the bottom of the clamping support 12 and a first rotating seat 51 protruding from the upper end face of the connecting platform 5. The first rotating connector 31 is inserted into the groove in the middle of the first rotating seat 51 and connected by a rotating shaft. The first rotating connector 3 is designed with damping pads or gear meshing structures inside. When adjusting the angle, external force needs to be applied to overcome the damping or gear friction. After being released, the angle is automatically locked to keep the mobile phone stably in the set position, realizing stepless angle adjustment. When shooting from above, it will not be unstable due to gravity, meeting the needs of front live broadcast, shooting desktop from above, and shooting side scenes.

[0029] The secondary handle 2 includes a fixing part 21 and an extension part 22. The fixing part 21 is rotatably connected to the connecting platform 5 via the second rotating connector 4. The extension part 22 is slidably connected to the fixing part 21 via a limiting structure 23. In its open state, the secondary handle 2 is used to store the remote control 6. A slot is provided at the connection point between the extension part 22 and the fixing part 21, based on the bottom shape of the remote control 6, to secure the remote control 6. In its stored state, the secondary handle 2 and the mobile phone clamping module 1 are together housed within the cavity of the fixing seat of the bottom support system of the shooting stand. The second rotating connector 4 includes a second rotating connector 211 disposed at the bottom of the fixed part 21 and a grooved rotating seat 52 disposed on the plane of the connecting platform 5. The second rotating connector 211 rotates relative to the grooved rotating seat 52 via a rotating shaft. The auxiliary handle 2 rotates 90° relative to the central telescopic rod assembly. In the use state, the auxiliary handle 2 is perpendicular to the central telescopic rod assembly. In the storage state, after rotation, the auxiliary handle 2 is located in the extension direction of the central telescopic rod, making it easy to store into the cavity of the upper fixed seat of the bottom support system. The auxiliary handle 2 serves as a handheld fulcrum, allowing manual adjustment of the height / angle during live streaming, replacing direct contact with the telescopic rod and preventing the rod from wobbling.

[0030] Furthermore, in the stowed state, the second rotating connecting part 211 and the large gear part 53 of the connecting platform 5 are provided with small teeth 2111 on their opposite surfaces. When the auxiliary handle 2 is rotated 180° downward from the upward stowed state, the small teeth 2111 mesh with the teeth of the large gear part 53, and the connecting platform 5 cannot rotate. This makes the top angle adjustment and clamping system and the middle telescopic rod assembly fixedly connected and unable to rotate relative to each other. At this time, it can be used as a handheld shooting stick.

[0031] The central telescopic rod assembly includes multiple concentric sleeves 7, consisting of at least two concentric sleeves 7. The more concentric sleeves 7 there are, the smaller the storage size of the live shooting rod will be, given the same maximum usable height. The diameter of the concentric sleeves 7 decreases sequentially. Each concentric sleeve 7 has a groove 71 or a protrusion at the same position on its body to restrict rotation of the central telescopic rod assembly during extension and retraction. Each concentric sleeve 7 has a limit groove or protrusion at its end to prevent excessive stretching and detachment, while ensuring coaxiality between adjacent sleeves after stretching. The locking mechanism between the concentric sleeves is a spring-loaded latch. Each concentric sleeve 7 has a spring pin at its end, which automatically pops out and locks when stretched to the positioning hole. Pressing the pin retracts the sleeve, achieving stepless adjustment and quick locking. Unlocking is achieved by pressing a button, and releasing the button automatically engages the sleeve positioning hole. The retracted outer rod 72 of the central telescopic rod assembly is housed within the cavity of the lower base of the bottom support system.

[0032] In another embodiment, a knob-type threaded lock is used, with an outer tube having an internal thread and an inner tube having an external thread. Rotating the outer tube locks the length through thread engagement, and rotating the outer tube locks the position of the inner tube through thread engagement, achieving stepless height adjustment within a certain range. The advantage is that the rigidity is stronger after locking, making it suitable for heavier equipment.

[0033] The internal cavity of the concentric sleeve 7 is reserved for charging cables and / or earphone cables, facilitating site cleanliness. The concentric sleeve is mostly made of lightweight alloys (such as aluminum alloys) or high-strength plastics, balancing weight and strength. After stretching, the sleeve sections form a "series force-bearing rod," transmitting the weight of the top phone and external operating forces, such as touching the phone to adjust its angle, to the bottom base through the concentric sleeve, where they are distributed to the ground by triangular support.

[0034] The bottom support system includes an upper fixed seat 8 and a lower fixed seat 9, with a fixed base 10 disposed between the upper fixed seat 8 and the lower fixed seat 9. The length of the upper fixed seat 8 is not less than the length of the top angle adjustment and clamping system when it is retracted. The lower fixed seat 9 includes three sets of support components 91 and a button component 92. The support component 91 includes a support foot 911, a connecting rod 912, and a magnet 913. The magnet 913 is disposed at the bottom of the support foot 911. The connecting rod 912 and the magnet 913 cooperate to open and close through magnetic attraction. The button component 92 includes a button base 921 and a button connecting part 922. A telescopic push rod 923 is accommodated between the button base 921 and the button connecting part 922. In the stowed state, the iron connecting rod 912 and the magnet 913 are attracted together by magnetic attraction. The button base 921 has a sloping boss 924 facing the interior of the lower fixed base 9. The cross-section of the sloping boss 924 is smaller at the top and larger at the bottom. In the stowed state, the upper end of the sloping boss 924 contacts one end of the retractable push rod 923, and the other end of the retractable push rod 923 contacts the end of the support foot 911. When it needs to be opened, press the button base 921 upward or strike the button base 921 downward to push the button base 921 with the help of the ground. The sloping boss 924 slides along the sloping surface to push the retractable push rod 923 out of the support foot 911, so that the support foot 911 is separated from the magnetic attraction of the connecting rod 912, and then unfolds the support foot 911 to provide stable support. The support foot 911 is radially distributed.

[0035] Furthermore, the retractable push rod 923 is provided with a return spring in the receiving groove of the button connection part 922. After the button assembly 92 is pressed, the retractable push rod 923 abuts against the larger cross-section of the inclined boss 924 under the sliding pushing action of the inclined boss 924. The return spring is compressed. When the support foot 911 is opened, the compression elastic potential energy of the return spring is converted into the kinetic energy of the retractable push rod 923, thereby retracting the retractable push rod 923 and restoring the button base 921 to its initial position.

[0036] Furthermore, the lower fixed base 9 is provided with anti-slip strips and / or counterweights to increase friction when in contact with the ground, suppress frame swaying, and counteract the "overturning moment" of the top equipment, such as the shaking force when a mobile phone is touched.

[0037] Furthermore, the lower end of the fixed base 10 is connected to the support assembly 91 via a hinged structure, allowing it to be folded for storage. When folded, the legs close to the rod body, reducing its volume; when unfolded, it utilizes triangular stability to provide rigid support for the entire structure. It serves as the connecting hub between the middle telescopic rod assembly and the bottom support system, and can be equipped with a locking mechanism inside. When the legs are unfolded, the mechanism locks to prevent accidental folding during use; when folded, it unlocks to allow the legs to rotate freely. The fixed base 10 has a sleeve interface that nests with the lower end of the concentric sleeve 7, secured by threads, snaps, or spring pins to ensure the stability of the telescopic rod under vertical force.

[0038] Furthermore, the clamping part 11 consists of a movable clamping arm and a fixed base 113. The movable clamping arm includes a left clamping arm assembly 111 and a right clamping arm assembly 112. The left clamping arm assembly 111 includes a left push rod 1111 and a left connecting rod 1112, and the right clamping arm assembly 112 includes a right push rod 1121 and a right connecting rod 1122. The left push rod 1111 is disposed in the middle internal cavity of the fixed base 113, and the right push rod 1121 is disposed in the internal cavities on both sides of the fixed base 113. The left push rod 1111 and the right push rod 1121 move relatively independently. The left connecting rod 1112 is disposed in the cavity of the left push rod 1111, and a first elastic element 1113 is disposed between the end of the left connecting rod 1112 and the end of the left push rod 1111. Both rod 1112 and the right connecting rod 1122 are composed of relatively movable concentric sliding rods. One end of the inner rod of the concentric sliding rod is fixedly connected to one end of the fixed seat 113, and one end of the outer rod of the concentric sliding rod is fixedly connected to the first elastic element 1113. The other end of the first elastic element 1113 is abutted by the end face of the inner cavity of the left push rod 1111. When an external force is applied to the left clamping arm assembly 111, the end face of the outer rod of the concentric sliding rod relative to the fixed seat 113 is stretched. At this time, the first elastic element 1113 is squeezed to provide clamping force. The working principle of the right clamping arm assembly 112 is the same as above. The clamp shape of the movable clamping arm is matched to form the same cross-section as the rod of the live shooting stand. It is not limited to the interlocking structure. The inner side of the clamp of the movable clamping arm is equipped with an anti-slip soft pad.

[0039] Furthermore, the side of the mobile phone clamping module 1 is provided with a cold shoe interface, magnetic contact or threaded connector for connecting external accessories such as fill lights and microphones to expand the live streaming function and upgrade the shooting stand from a "single mobile phone stand" to a "small live streaming ecosystem platform".

[0040] The above examples are merely specific embodiments of this utility model. Obviously, this utility model is not limited to the above embodiments, and many similar modifications are possible. All variations that can be directly derived or conceived by those skilled in the art from the content disclosed in this utility model should be considered within the scope of protection of this utility model.
