[0027] This utility model proposes a cold shoe mount 100 for connecting shooting equipment and extension equipment. The shooting equipment is provided with a first cold shoe interface and / or a second cold shoe interface. (Refer to...) Figures 1 to 3 The cold shoe mount 100 includes a base 110 and a connector 130. One side of the base 110 is used to connect an extension device, and two opposite sides of the other side of the base 110 extend to form an extension portion 112. The two extension portions 112 are used to insert and connect with a first cold shoe interface (slot). The first cold shoe interface is a slot that matches the extension portion 112. One end of the connector 130 is used to detachably connect with the base 110, and the other end of the connector 130 is used to connect with a second cold shoe interface.

[0028] In this embodiment, the base 110 serves as the main support of the entire cold shoe mount 100, providing stable connection and support for the magnetic component 120 and the connector 130. The base 110 is made entirely of ABS engineering plastic, which is sturdy, durable, and wear-resistant, making it suitable for repeated insertion and removal. On the other side of the base 110, two extensions 112 protrude from opposite sides. These two extensions 112, along with the other surface of the base 110, are inserted into the connecting groove of the first cold shoe interface, allowing the cold shoe mount 100 to be plugged into the first cold shoe interface for easy installation and disassembly, enabling rapid switching of the cold shoe mount 100's position. In a preferred embodiment, the two extensions 112 and the base 110 are integrally molded by injection molding, facilitating manufacturing and improving the connection strength between the extensions 112 and the base 110, thereby enhancing the overall strength of the cold shoe mount 100. Specifically, the two extensions 112 are interference-fitted with the first cold shoe interface. When the two extensions 112 are inserted into the first cold shoe interface, the extensions 112 and the first cold shoe interface can self-lock and clamp together due to the dimensional fit between them. This eliminates the need for additional connecting structures between the cold shoe holder 100 and the first cold shoe interface, resulting in a simpler overall structure and easier installation and disassembly. In a preferred embodiment, each extension 112 has chamfers at both ends along the direction of insertion into the first cold shoe interface to facilitate smoother insertion and, consequently, smoother connection between the cold shoe holder 100 and the first cold shoe interface, enabling quick removal and installation of the cold shoe holder 100.

[0029] The connector 130 provides a second connection method for the cold shoe mount 100. One end of the connector 130 is detachably connected to the base 110 of the cold shoe mount 100, which can be achieved through threaded connection or snap-fit ​​connection. The other end of the connector 130 is used to connect to a rabbit cage with a connection hole, a tripod with a connection hole, or other locations or structures with connection holes, which can also be achieved through threaded connection or plug-in connection. The connector 130 can be made of 1 / 4-inch screws or bolts to fit the threaded holes on common rabbit cages on the market.

[0030] The cold shoe mount 100 proposed in this utility model has two connection modes. One mode is without the connector 130, in which the two extensions 112 at both ends of the base 110 of the cold shoe mount 100 are directly plugged into the first cold shoe interface, and it can be installed at any position with the first cold shoe interface. The other mode is with the connector 130, in which the cold shoe mount 100 is installed at any position with a connection hole that is compatible with the connector 130. Compared with the traditional cold shoe mount 100, which can only be connected to the first cold shoe interface, the installation position of the cold shoe mount 100 is more flexible, the application scenarios are more diverse, and the user experience is improved.

[0031] The cold shoe mount 100 proposed in this utility model includes a base 110 and a connector 130. One side surface of the base 110 is used to connect with an extension component; two extensions 112 are formed on opposite sides of the other side of the base 110, and the two extensions 112 are used to plug into and connect with a first cold shoe interface; one end of the connector 130 is detachably connected to the base 110, and the other end is used to connect with a rabbit cage. The beneficial effects of this utility model are: the cold shoe mount 100 adapts to the first cold shoe interface (slot type) through the extensions 112, and adapts to the second cold shoe interface (such as a threaded hole or other types) through the connector 130, which can simultaneously or individually match shooting equipment with different interfaces, improve versatility, and reduce usage costs.

[0032] In some embodiments, refer to Figure 3 The cold shoe mount 100 also includes a magnetic element 120. The base 110 has a receiving cavity 111 on one side, and the magnetic element 120 is disposed in the receiving cavity 111. The extension device can be magnetically connected to the surface of one side of the base 110 through the magnetic element 120.

[0033] In this embodiment, the magnetic component 120 is a magnetic force-providing element disposed within the receiving cavity 111 of the base 110, making one side surface of the base 110 magnetic, enabling magnetic connection of external devices such as fill lights or microphones. Specifically, the magnetic component 120 can be a commercially available neodymium iron boron magnet, which has a strong magnetic force, thus making the connection between the extension device and the cold shoe mount 100 more stable and preventing the extension device from falling during use, causing interruption of shooting or injury. The magnetic component 120 can also be other magnetic elements, such as ferrite magnets. The specific selection of the magnetic component 120 should be determined according to actual needs, such as magnetic strength and application scenario, and is not further limited here. The magnetic component 120 is disposed within the receiving cavity 111. The connection between the magnetic component 120 and the cavity wall, top, or bottom of the receiving cavity 111 can be achieved by adhesive bonding. Specifically, the magnetic component 120 can be glued to the inner wall of the top of the receiving cavity 111, so that one side surface of the base 110 becomes magnetic, allowing for magnetic connection with the expansion device. Alternatively, a baffle with the same shape as the magnetic component 120 can be protruded from the inner wall of the top of the receiving cavity 111. The magnetic component 120 is embedded in the area enclosed by the baffle and is interference-fitted with the baffle, thereby securing the magnetic component 120 to the top of the receiving cavity 111, so that one side surface of the base 110 becomes magnetic, allowing for magnetic connection with the expansion device.

[0034] A receiving cavity 111 is formed inside one side of the base 110. The receiving cavity 111 is used to place the magnetic component 120, so that the surface of one side of the base 110 is magnetic, which can be magnetically connected to external expansion components such as fill lights or microphones. Magnetic connection has the advantages of convenient connection and safe durability. Compared with the traditional plug-in connection, magnetic connection only requires bringing the magnetic component 120 close together to attract it, without the need for precise alignment of the connector. It is especially convenient in some low-light or difficult-to-operate scenarios. Moreover, since the connection process is a smooth magnetic attraction, rather than a rigid insertion connection, it greatly reduces the mechanical wear of the cold shoe mount 100 itself and extends the service life of the cold shoe mount 100.

[0035] In some embodiments, refer to Figure 2 The second cold shoe interface is a connection hole. The bottom of the cavity 111 has a countersunk hole 1111. One end of the connector 130 is used to be locked in the countersunk hole 1111. The other end of the connector 130 passes through the countersunk hole 1111 and is partially exposed on the other side surface of the base 110 for connection with the connection hole.

[0036] In this embodiment, the countersunk hole 1111 is a stepped hole structure. The countersunk hole 1111 is formed on the bottom of the receiving cavity 111. For example, one end of a connector 130, such as a screw or bolt, can be engaged with the stepped surface of the countersunk hole 1111, and the other end can pass through the countersunk hole 1111 and be partially exposed on the other side surface of the base 110 for connection with the matching connecting hole of the connector 130, so as to fix the cold shoe holder 100 in the corresponding position. Compared with connection methods such as threaded connection, one end of the connector 130 is engaged with the stepped surface of the countersunk hole 1111. When disassembly is required, only the other end of the connector 130 needs to be removed to remove the cold shoe holder 100, making the disassembly or installation of the cold shoe holder 100 more convenient and saving installation and disassembly time.

[0037] When the cold shoe mount 100 adopts the second connection method, the other end of the connector 130 passes through the countersunk hole 1111 and is partially exposed on the other side surface of the base 110, connecting with the matching connection hole. This causes one end of the connector 130 to be engaged with the stepped surface of the countersunk hole 1111, ultimately fixing the cold shoe mount 100 in the position corresponding to the connection hole. For disassembly, simply disconnect the other end of the connector 130 from the connection hole to remove the cold shoe mount 100 from that position.

[0038] In some embodiments, refer to Figure 3 The bottom of the cavity 111 is provided with a receiving groove 1112, and the magnetic component 120 is disposed in the receiving groove 1112.

[0039] In this embodiment, the receiving groove 1112 is a recessed structure for placing the magnetic component 120. Specifically, it has the same outer peripheral shape as the magnetic component 120, but its size is slightly larger than the groove of the magnetic component 120. This ensures a stable connection between the magnetic component 120 and the base 110, preventing the magnetic component 120 from moving around in the receiving cavity 111, which could cause magnetic connection failure or magnetic connection position misalignment. The specific connection method between the magnetic component 120 and the receiving groove 1112 can be an interference fit plug connection, an adhesive connection, or a combination of the two connection methods to further improve the connection strength between them.

[0040] It is understood that in other embodiments, the base 110 may adopt a split structure, including a base and a cover plate. One side of the base is provided with an open receiving cavity 111. The cover plate is interference-fitted with the opening of the receiving cavity 111 to close the opening of the receiving cavity 111 and to press the magnetic component 120 against the receiving groove 1112 without the need for additional connection methods. The cover plate is provided with a hole for the connector 130 to pass through. When connecting and disconnecting the connector 130, the connector 130 can be pulled out from the hole without removing the cover plate.

[0041] In some embodiments, please refer again Figure 3 There are two receiving slots 1112 and two magnetic components 120. The two receiving slots 1112 are spaced apart at the bottom of the receiving cavity 111, and one magnetic component 120 is disposed in one receiving slot 1112.

[0042] In this embodiment, there are two magnetic components 120. Increasing the number of magnetic components 120 enhances the magnetic attraction of the cold shoe mount 100, thereby making the connection between the extension device and the cold shoe mount 100 more stable and preventing problems such as the extension device falling during use, causing interruption of shooting or personal injury. Correspondingly, the bottom of the receiving cavity 111 has two spaced receiving slots 1112 for placing the magnetic components 120. This prevents the magnetic components 120 from moving around in the receiving cavity 111, causing magnetic connection failure or magnetic connection position displacement. Furthermore, the two spaced receiving slots 1112 can also prevent the two magnetic components 120 from interfering with or attracting each other, thus weakening the magnetic force and affecting the use of the extension device.

[0043] Understandably, in a preferred embodiment, the opposite side walls of the receiving cavity 111 each extend to form a wing, and each wing has a receiving groove 1112 for placing the magnetic component 120. The line connecting the centers of the two wing portions is parallel to the line connecting the centers of the two extension portions 112, and the projections of the two wing portions on the other side surface of the base 110 overlap with the two extension portions 112, so that the cold shoe base 100 has a more uniform and aesthetically pleasing appearance.

[0044] In some embodiments, refer to Figure 3 Two receiving grooves 1112 are symmetrically arranged on opposite sides of the countersunk hole 1111 with the central axis of the countersunk hole 1111 as the axis.

[0045] In this embodiment, two receiving grooves 1112 are formed on opposite sides of the countersunk hole 1111 with the central axis of the countersunk hole 1111 as the axis of symmetry. A magnetic element 120 is provided in one receiving groove 1112. The two magnetic elements 120 are also arranged on opposite sides of the countersunk hole 1111 with the central axis of the countersunk hole 1111 as the axis of symmetry. This makes the magnetic field generated by the two magnetic elements 120 on the surface of the base 110 more uniform, and the resulting magnetic attraction force is also uniform. Ultimately, this makes the connection between the extension device and the cold shoe mount 100 more stable, preventing the extension device from falling during use and causing problems such as interruption of shooting or injury to personnel.

[0046] It is understood that, in a preferred embodiment, the bottom of the cavity 111 of the base 110 is provided with multiple non-penetrating hollow structures, which can reduce the overall weight of the cold shoe 100 as much as possible without affecting the sealing performance, making the cold shoe 100 simpler and lighter, and improving the user experience.

[0047] In some embodiments, refer to Figure 3 The two magnetic components 120 have opposite magnetic properties on the surfaces of the cavity tops of the receiving cavity 111.

[0048] In this embodiment, the magnetic poles of the two magnetic elements 120 facing the top of the cavity are opposite. For example, the magnetic pole of one magnetic element 120 facing the top of the cavity is the south pole, and the magnetic pole of the other magnetic element 120 facing the top of the cavity is the north pole. Correspondingly, the magnetic poles of the two opposing magnetic elements 120 on the extension assembly are also opposite, so as to attract each other with the two magnetic elements 120 on the cold shoe mount 100. The magnetic attraction between the two magnetic elements 120 on the cold shoe mount 100 and the two magnetic elements 120 on the extension assembly improves the connection stability between the cold shoe mount 100 and the extension assembly. It is understood that in another embodiment, the magnetic poles of the two magnetic elements 120 facing the top of the cavity can also be the same. Correspondingly, the magnetic poles of the two opposing magnetic elements 120 on the extension assembly are also the same and opposite to the polarity of the magnetic elements 120 on the cold shoe mount 100, so as to magnetically connect the cold shoe mount 100 and the extension assembly. Of course, in another embodiment, the expansion component may also be provided with a non-magnetic but magnetic metal that can be attracted by the magnetic element 120, such as iron and its alloys, nickel and its alloys, cobalt and its alloys, etc. The magnetic element 120 on the cold shoe 100 is magnetically connected to the magnetic metal in the expansion component, thereby realizing the connection between the cold shoe 100 and the expansion component.

[0049] In some embodiments, refer to Figure 3The cavity top of the receiving cavity 111 is provided with a relief opening 1113 that communicates with the countersunk hole 1111, and the connector 130 can be inserted into the countersunk hole 1111 through the relief opening 1113.

[0050] In this embodiment, the clearance opening 1113 is a hole-like structure formed at the top of the receiving cavity 111, for the connector 130 to pass through, allowing the connector 130 to be inserted into the countersunk hole 1111. One end of the connector 130 can be engaged on the stepped surface of the countersunk hole 1111, and the other end of the connector 130 can pass through the countersunk hole 1111 and partially protrude on the other side surface of the base 110, thereby connecting with the connection hole to connect the cold shoe holder 100 to the structure with the connection hole. By opening the clearance opening 1113 at the top of the receiving cavity 111, the installation and removal of the connector 130 can be completed directly through the clearance opening 1113 without disassembling other components, thereby improving the convenience of installing and removing the cold shoe holder 100 and enhancing the user experience.

[0051] In some embodiments, refer to Figure 2 The other side surface of the base 110 is provided with a protrusion 113, which is used to abut against the surface of the first cold shoe interface to lock the extension 112 to the first cold shoe interface.

[0052] In this embodiment, the protrusion 113 is a protruding structure provided on the other side surface of the base 110. When the two extensions 112 of the base 110 are inserted into the first cold shoe interface, the protrusion 113 is sandwiched between the other side surface of the base 110 and the surface of the first cold shoe interface. Through the slight deformation of the protrusion 113, the other side of the base 110 can achieve the effect of locking the base 110 and the first cold shoe interface, thereby improving the connection strength between the two and preventing the cold shoe holder 100 from being dislodged from the first cold shoe interface by a slight external force, which could cause the extended device to fall during use, resulting in interruption of shooting or injury to personnel.

[0053] In a preferred embodiment, the protrusion 113 is an arc-shaped protrusion. When the two extensions 112 on the other side surface of the base 110 are inserted into the first cold shoe interface, the arc-shaped protrusion 113 will not hinder the insertion process. After insertion, the arc-shaped protrusion 113 can be slightly deformed by the pressure between the other side surface of the base 110 and the surface inside the first cold shoe interface, which plays a role similar to an interference fit, so that the cold shoe seat 100 and the first cold shoe interface can be locked together, improving the connection stability between the two.

[0054] In some embodiments, refer to Figure 2 The number of protrusions 113 is multiple, and the multiple protrusions 113 are evenly distributed at intervals along the circumferential direction of the other side surface of the base 110.

[0055] In this embodiment, there are multiple protrusions 113, which enable multiple points of engagement between the other side surface of the base 110 and the surface of the first cold shoe interface, further enhancing the connection strength between the cold shoe holder 100 and the first cold shoe interface. The multiple protrusions 113 are evenly distributed along the circumferential direction of the other side surface of the base 110, ensuring that the engagement force between the other side surface of the base 110 and the surface of the first cold shoe interface is also evenly distributed along the circumferential direction of the other side surface of the base 110, thereby making the connection between the cold shoe holder 100 and the first cold shoe interface more stable.

[0056] When the extension 112 of the cold shoe mount 100 is inserted into the first cold shoe interface, the multiple protrusions 113 are subjected to the clamping force between the base 110 and the first cold shoe interface, and undergo slight deformation, which plays a role similar to interference fit, so that the cold shoe mount 100 and the first cold shoe interface can be locked together, thereby improving the connection strength between the two.

[0057] This utility model further proposes a fill light assembly (not shown) including a fill light body (not shown) and a cold shoe mount 100.
