Description

Technical Field

[0001] This utility model relates to the field of screw technology, specifically a multi-functional screw for photographic equipment. Background Technology

[0002] Photographic equipment is a general term encompassing cameras, lenses, related accessories, and various devices and items related to photographic activities. This includes consumables such as film, as well as items sold by most photographic equipment dealers, such as camera vests and bags. Photographers often assemble and secure multiple pieces of equipment or accessories for use during photographic activities.

[0003] In the prior art, the outer circle of the existing screw body is mostly a smooth cylindrical surface or only has a single thread structure. Moreover, there is no through hole specifically set below the external thread at the top of the screw body for installation and disassembly. The installation and disassembly operations mainly rely on the slotted, cross-shaped, or internal hexagonal slot opened at the top of the screw body, and the screw is turned by matching screwdrivers, internal hexagonal wrenches, and other tools.

[0004] However, the smooth cylindrical surface of the screw body or the single thread structure, as well as the installation and disassembly method that relies solely on the top groove, have significant operational limitations. When the screw body is tightened, excessive force can cause the threads to be over-compressed and deformed, or after long-term use, the threads may rust or become misaligned, causing the screw body to become stuck inside the outer pipe. It is difficult to apply effective force using only traditional screwdrivers, Allen wrenches, and other tools, making it impossible to complete the disassembly operation smoothly. Often, it is necessary to use violent methods such as cutting or destruction, which not only damages the screw body itself but may also damage the outer pipe to which it is connected, increasing maintenance costs and operational difficulty.

[0005] In light of this, we are introducing a multi-functional screw for photographic equipment. Utility Model Content

[0006] The purpose of this invention is to provide a multifunctional screw for photographic equipment to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional screw for photographic equipment, comprising: a screw body, an external thread portion B, and a cavity;

[0008] The screw body is installed on the pipe. A threaded post is provided on one side of the top of the screw body. The screw body and the threaded post are integrally formed. The surface of the threaded post is provided with an external thread A. The cavity is opened inside the screw body and is fixed to the pipe to be connected so as to assemble it into photographic equipment.

[0009] Preferably, the top of the screw body is provided with a through hole for installation and removal below the external thread portion A.

[0010] Preferably, the cavity and the screw body are integrally formed.

[0011] Preferably, the outer circle of the screw is designed as a polygonal structure for installation and removal.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) By using an integral molding design for the screw body and threaded column, and the cavity and screw body, this integrated structural design reduces the number of parts and eliminates the assembly steps between multiple parts. The connection between the screw and the pipe, camera or sports equipment can be quickly completed by following the basic installation process, which improves work efficiency. The integrated structural design avoids the adhesion of the threaded column, cavity and screw body during assembly, making it more robust and durable during use. It can effectively prevent the threaded column, cavity and screw body from falling off and separating due to excessive force by the user when disassembling the screw.

[0014] (2) By setting the polygonal structure of the outer circle of the screw body and the through hole below the top external thread for installation and disassembly, a convenient operation method is provided for installation and disassembly; it can effectively deal with the situation where the screw body is stuck in the outer pipe due to over-tightening or thread deformation and misalignment.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved with", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a multi-functional screw for photographic equipment, comprising: a screw body 500, the screw body 500 being made of high-strength aluminum alloy (combining lightweight and structural strength), adapted to be installed in a pre-set mounting hole in a photographic tube (such as a tripod leg, a ball head connecting rod, etc.), a threaded post 600 being coaxially provided on one side of the top of the screw body 500, the screw body 500 and the threaded post 600 being integrally formed, the surface of the threaded post 600 being provided with an external thread portion A200, the external thread portion A200 adopting a 1 / 4-inch standard camera thread specification (compatible with the bottom screw holes of mainstream cameras and action cameras), the external thread portion A200 on the surface of the threaded post 600 can be directly screwed into the threaded hole of the camera or action equipment for fixation, realizing a quick connection between the equipment and the tube.

[0023] The external thread section B400 is located on the side of the threaded post 600 away from the screw body 500 (forming a stepped distribution with the external thread section A200). Its specification is a 3 / 8-inch standard thread (suitable for the connection requirements of large photographic equipment). The external thread section B400 is used to connect with the internal threads of external extension tubes, adapter sleeves, etc. By adjusting the thread engagement depth, the fixed tube can achieve fixed length or height adjustment to meet the height requirements of different shooting scenarios.

[0024] Cavity 300 is a cylindrical groove located inside the screw body 500 on the side away from the threaded post 600. The inner wall of the groove is provided with anti-slip texture (to increase friction with the tube). The inner diameter of cavity 300 matches the outer diameter of the photographic tube to be connected. It is fixed to the tube to be connected by interference fit or by fastening screws, so as to quickly assemble photographic equipment such as tripods and monopods and improve assembly efficiency.

[0025] The outer circumference of the screw body 500 has a through hole 100 in the radial direction. The operator can insert a special pin into the through hole 100 and apply a greater torque with a tool to easily rotate the screw body 500 to remove the screw.

[0026] The cavity 300 and the screw body 500 are integrally formed. The screw body 500 is directly machined inside the screw body 500 to avoid precision errors caused by secondary assembly, ensure the coaxiality of the cavity 300 and the screw body 500, and guarantee the perpendicularity of the pipe after connection.

[0027] The outer circle of the screw body 500 is a regular hexagon (i.e., a hexagonal head structure), which is compatible with standard wrench tools and facilitates the application of torque during installation or disassembly. At the same time, the hexagonal structure can prevent the screw body 500 from rotating circumferentially inside the pipe, thereby improving the reliability of the overall connection.

[0028] Specifically, in use, the screw body 500 serves as the basic load-bearing component of the entire screw. The first step is to install it onto the base tube of the photographic equipment. During installation, the operator can easily rotate the screw body 500 using tools such as a wrench, taking advantage of the polygonal structure of its outer circle, to initially connect it with the base tube. At this point, the cavity 300 inside the screw body 500 plays a crucial role. The cavity 300 and the screw body 500 are integrally molded, resulting in strong structural stability. The tube to be connected can be precisely embedded into the cavity 300, and the cavity 300 is fixed by its tight fit with the tube, thus completing the stable connection between the screw body 500 and the base tube, laying the foundation for the installation of other components.

[0029] A threaded post 600 is provided on one side of the top of the screw body 500, and the two are integrally formed. This structural design not only eliminates the need for additional connection steps, but also reduces assembly errors.

[0030] After the screw body 500 is fixed to the base pipe, the camera or sports equipment can be installed and fixed. The surface of the threaded post 600 is provided with an external thread A200. The operator can align the threaded interface on the camera or sports equipment with the external thread A200, and then slowly rotate the camera or sports equipment to make the external thread A200 gradually engage with the threaded interface of the equipment. During the rotation, the thread structure of the external thread A200 can provide stable friction to ensure that the camera or sports equipment will not easily loosen after installation. Since the threaded post 600 and the screw body 500 are integrally formed, the overall structure is stable and can effectively bear the weight of the camera or sports equipment, so as to achieve reliable fixation of the camera or sports equipment and meet the needs of stable placement of equipment during photography.

[0031] If it is necessary to expand the structure of photographic equipment and add additional tubes to meet the needs of different shooting scenarios, the external threaded part B400 provided on one side of the threaded column 600 can be used to process an internal thread that matches the external threaded part B400 at one end of the tube to be connected. Then, the internal thread of the tube is aligned with the external threaded part B400 and rotated to make the two tightly connected. The external threaded part B400 has high thread precision, which can ensure the sealing and stability of the connection with the tube and prevent the tube from falling off or shaking during use. This allows for the assembly of multiple tubes, expanding the function and scope of use of photographic equipment.

[0032] The outer circumference of the screw body 500 is provided with a through hole 100. The through hole 100 plays an important auxiliary role in actual use. When it is necessary to disassemble or maintain the screw, it is difficult to turn the screw by relying solely on the polygonal structure of the outer circumference of the screw body 500. The operator can insert a special disassembly tool (such as a pin) into the through hole 100 and apply greater torque by the tool to easily turn the screw body 500 and disassemble the screw.

[0033] By setting the polygonal structure of the outer ring of the screw body 500 and the through hole 100 below the top external thread, a convenient operation method is provided for installation and disassembly; it can effectively deal with the situation where the screw body 500 gets stuck due to over-tightening or thread deformation and misalignment.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
