Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a quick-connect connector with connection feedback. Background Technology

[0002] In scenarios such as underwater photography, environmental detection, and scene lighting, it is often necessary to combine multiple lenses, multiple sensors, and multiple light sources. In such scenarios where multiple devices work together in coordination, operators often need to use connectors to connect different devices and quickly disassemble or replace a specific device according to the specific needs of the scenario.

[0003] The connectors provided in the prior art are usually in the form of a single magnetic connection or threaded connection.

[0004] Taking underwater photography as an example, connectors are typically used as extension connectors to connect extension lenses, supplementary lights, or submersible sensors in underwater photography scenarios. When connectors with a single magnetic connection are applied to specific underwater photography scenarios, the connection strength depends entirely on the magnetic force of the magnetic structure. They are easily loosened by underwater currents or external impacts, making their connection strength insufficient for the requirements of specific applications. On the other hand, when connectors with a single threaded connection are applied to specific underwater photography scenarios, users need to carefully adjust the connector's position and strictly align the threads at both ends before connecting. The tightening process lacks feedback, requiring users to carefully observe to determine if it is tightened correctly. This is extremely inconvenient in underwater photography scenarios with poor visibility, high water pressure, and difficult movement, resulting in a poor user experience. Utility Model Content

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain this utility model and do not constitute a limitation on this utility model.

[0033] Please see Figure 1-2 In this specific embodiment, a quick-connect connector with connection feedback is provided, including a first connector 1, a second connector 2, a sleeve 3, a ball assembly 4, a first ball head 5, and a second ball head 6;

[0034] The first ball head 5 is located on the side of the first connector 1 away from the sleeve 3, and the first ball head 5 is fixedly connected to the first connector 1; the second ball head 6 is located on the side of the second connector 2 away from the first connector 1, and the second ball head 6 is fixedly connected to the second connector 2. When specifically applied to underwater photography scenarios, the first ball head 5 can be fixed to underwater supplementary lighting equipment such as a butterfly clip, and the second ball head 6 can be fixed to water pressure sensors, underwater cameras, and other equipment such as another butterfly clip. In this way, two or more devices can be connected together to form a whole and move together through the connector provided in this specific embodiment, or they can be disassembled into individual devices for each other to use.

[0035] Please see Figure 1-7In this specific embodiment, the sleeve 3 is sleeved on and connected to the first connecting member 1. The inner wall of the sleeve 3 has an internal thread 31 and a concave ring 32. The second connecting member 2 is provided with an external thread 21 that matches the internal thread 31. The ball bearing assembly 4 is disposed on the second connecting member 2, and the ball bearing assembly 4 is retractably protruding from the second connecting member 2. The external thread 21 is screwed into the internal thread 31 to connect the first connecting member 1 and the second connecting member 2, or the external thread 21 is screwed out of the internal thread 31 to separate the first connecting member 1 and the second connecting member 2. The mutual cooperation between the external thread 21 and the internal thread 31, where the external thread 21 is screwed into the internal thread 31, then... The first connector 1 and the second connector 2 are connected. The external thread 21 is removed from the internal thread 31, and the first connector 1 and the second connector 2 are separated. The disassembly and assembly process is very convenient and quick. Since the external thread 21 and the internal thread 31 are interlocked, they cooperate with each other in a threaded structure. Compared with the single magnetic connection structure in the prior art, the connector provided in this specific embodiment will have higher connection strength and can resist greater external impact. When applied to underwater photography and other scenarios, it can resist the risks of water flow, surge, and rock collision to a greater extent, and maintain a stable and reliable connection between devices.

[0036] During the process of the external thread 21 being inserted into the internal thread 31 or the external thread 21 being pulled out of the internal thread 31, the ball assembly 4 will regularly strike the concave ring 32 to form a connection feedback. On the one hand, the periodic tapping of the ball assembly 4 against the concave ring 32 will produce a "click-click" sound, which the user can clearly hear in a non-underwater environment. On the other hand, the periodic tapping of the ball assembly 4 against the concave ring 32 will also transmit a regular and rhythmic tactile feedback to the user, which the user can clearly feel in an underwater environment. That is, the ball assembly 4 and the concave ring 32 in the connector provided in this specific embodiment will provide the user with clear connection feedback. When the user holds the connector and connects or disconnects the first connector 1 and the second connector 2, the "click-click" sound and rhythmic tactile feedback generated by the mutual impact between the ball assembly 4 and the concave ring 32 will clearly indicate the connection status of the first connector 1 and the second connector 2. This helps the user to disconnect blindly. The user does not need to carefully observe the two devices to be connected with the naked eye, but can easily assemble and disassemble them by hearing or feeling.

[0037] Please see Figure 2-3In this specific embodiment, the ball assembly 4 includes a spring (not shown), a top bead 41, and a ball shell 42. The spring is installed in the ball shell 42, with one end of the spring connected to the ball shell 42 and the other end connected to the top bead 41. The top bead 41 compresses the spring and is retractably ejected from the opening of the ball shell 42. A blind hole 22 is radially formed on the side wall of the second connector 2, and the ball shell 42 is embedded in the blind hole 22. The top bead 41 reciprocates radially to compress the spring. Select a spring with a suitable elastic coefficient, and pre-embed one or more symmetrical ball bearing assemblies 4 in the side wall of the second connector 2. Each ball bearing assembly 4 is arranged radially along the second connector 2. In this way, the ball bearing assembly 4 can be retractably ejected from the blind hole 22. The concave ring 32 is set in conjunction with the ball bearing assembly 4. When the user holds the first connector 1 and the second connector 2 with both hands respectively, and inserts the external thread 21 into the internal thread 31, since the ball bearing assembly 4 is embedded in the second connector 2, the ball bearing assembly 4 moves together with the second connector 2. The concave ring 32, which presents a continuous and uniform undulating shape, periodically squeezes the top ball 41 and the spring, producing a "click-click" sound and a regular, rhythmic tapping sensation. When the external thread 21 is fully inserted into the internal thread 31 and the first connector 1 and the second connector 2 are firmly connected, the ball bearing assembly 4 will abut against a certain position of the concave ring 32. The cooperation between the ball bearing assembly 4 and the concave ring 32 provides the user with clear connection feedback, helping the user to blindly disassemble and assemble without having to carefully observe the alignment with the naked eye.

[0038] Please see Figure 1-7In this specific embodiment, the concave ring 32 is disposed on the inner wall of the sleeve 3 on the side away from the first connecting member 1. The internal thread 31 on the inner wall of the sleeve 3 is disposed at the end of the sleeve 3 near the first connecting member 1, and the concave ring 32 is disposed at the end of the sleeve away from the first connecting member 1. Distributing the internal thread 31 on the inner wall of the sleeve 3 near the first connecting member 1 and the concave ring 32 on the inner wall of the sleeve 3 away from the first connecting member 1 means that the concave ring 32 has an internal thread at its rear end, and the activation time of the concave ring 32 will lag behind the activation time of the internal thread 31. After the second connecting member 2 is inserted into the sleeve 3, the external thread 21, which is an external thread, will first engage with the internal thread 31, and the ball assembly 4 has not yet contacted the concave ring 32 at this time. As the second connecting member 2 is continuously screwed in, the ball assembly 4 continues to extend into the sleeve 3. When the ball assembly 4 begins to contact the concave ring 32... When the concave ring 32 is engaged, it periodically compresses the top ball 41 and the spring. The ball assembly 4 periodically strikes the concave ring 32, producing a "click-click" sound. At this point, the external thread 21 is mostly embedded in the internal thread 32. The user can clearly know from the "click-click" sound that the connection process is nearing completion. Continue screwing in the second connector 2, fully screwing the external thread 21 into the internal thread 31, so that the external thread on the second connector 2 is fully engaged with the internal thread of the sleeve. The user can clearly know from the sound and feel that the first connector 1 and the second connector 2 are fully connected, without needing to observe with the naked eye. By placing the concave ring 32 behind the internal thread 31, the activation time of the concave ring 32 can clearly indicate to the user that the connection is complete, helping the user to install blindly. The disassembly process of the first connector 1 and the second connector 2 is the same. The user holds the first connector 1 and the second connector 2 with both hands respectively, and loosens the internal thread 31 and the external thread 21 in opposite directions. When the user starts to loosen the thread, the ball assembly 4 periodically taps the concave ring 32 and makes a "click-click" sound. As the second connector 2 continues to be unscrewed, the external thread 21 continues to be unscrewed. The ball assembly 4 retreats to the area where there is no concave ring 32, and the connector no longer makes a "click-click" sound. Continue to unscrew the second connector 2 until the second connector 2 is completely separated from the first connector 1 and the two are completely separated. During the above disassembly process, the ball assembly 4 periodically taps the concave ring 32 and makes a "click-click" sound to indicate the disassembly progress and help the user to disassemble blindly.

[0039] Please see Figure 1-27. In this specific embodiment, it also includes a first magnet 7 and a second magnet 8; the first magnet 7 is disposed on the side of the first connector 1 near the sleeve 3, and the first magnet 7 is connected to the first connector 1; the second magnet 8 is disposed on the side of the second connector 2 near the first connector 1, and the second magnet 8 is connected to the second connector 2, and the first magnet 7 and the second magnet 8 attract each other. By setting the first magnet 7 and the second magnet 8, the attraction between the two can automatically and conveniently connect the first connector 1 and the second connector 2. In scenarios with blurred vision and low visibility, such as underwater photography, the first magnet 7 and the second magnet 8 will help the first connector 1 and the second connector 2, which are in a disassembled state, to quickly and directly align and attract each other, making it convenient for the user to tighten and connect them later.

[0040] Please see Figure 1-4 7. To ensure the stability and reliability of the first magnet 7 and the second magnet 8, in this specific embodiment, the first connector 1 is provided with a first magnet receiving cavity 11, which is located at the end of the first connector 1 near the sleeve 3. The first magnet receiving cavity 11 is adapted to the first magnet 7, and the first magnet 7 is embedded in the first magnet receiving cavity 11. The second connector 2 is provided with a second magnet receiving cavity 23, which is located at the end of the second connector 2 near the first connector 1. The second magnet receiving cavity 23 is adapted to the second magnet 8, and the second magnet 8 is embedded in the second magnet receiving cavity 23. Through the first magnet receiving cavity 11 and the second magnet receiving cavity 23, the first magnet 7 will be securely and reliably embedded in the end of the first connector 1 near the sleeve 3, and the second magnet 8 will be securely and reliably embedded in the end of the second connector 2 near the first connector 1. When the user holds the first connector 1 and the second connector 2 with both hands and brings them close together, the first connector 1 and the second connector 2 will attract each other through the mutual attraction between the first magnet 7 and the second magnet 8, and automatically align and engage. This setting will help the user to automatically align the two connectors underwater or in other harsh environments with low visibility, without having to carefully observe and align them with the naked eye.

[0041] Please see Figure 1-3 In this specific embodiment, at least one locking groove 12 is also provided on the first connector 1, and the locking grooves 12 are spaced apart on the end face of the first connector 1 near the second connector 2; at least one locking protrusion 24 is also provided on the second connector 2, and the locking protrusion 24 is adapted to the locking groove 12. When the external thread 21 is fully embedded in the internal thread 31, the locking protrusion 24 is embedded in the locking groove 12. The tight fit between the locking protrusion 24 and the locking groove 12 helps to increase the connection strength between the first connector 1 and the second connector 2, helps to resist external force damage, and obtains a more stable and reliable connection structure.

[0042] Please see Figure 1-2 4. In this specific embodiment, a stop end cap 9 is also included. The stop end cap 9 is disposed on the side of the second connector 2 away from the sleeve 3, and the stop end cap 9 is integrally formed with the second connector 2. The stop end cap 9 is disposed on the second connector 2 away from the sleeve 3 and close to the second ball head 6. The stop end cap 9 serves as a separator between the second connector 2 and the second ball head 6. When the external thread 21 on the second connector 2 is fully screwed into the internal thread 31 of the sleeve 3, the stop end cap 9 is completely pressed against the sleeve 3, completely covering the connection between the second connector 2 and the sleeve 3. This prevents the second connector 2 from being over-tightened and provides a certain degree of waterproof and dustproof protection to the connection between the second connector 2 and the sleeve 3.

[0043] Please see Figure 1-2 5. In this specific embodiment, the outer wall of the sleeve 3 is provided with a plurality of friction embossing patterns 33. The friction embossing patterns 33 help to increase the friction between the user's hand and the sleeve 3, making it easier for the user to hold the sleeve 3 or tighten / loosen the sleeve 3. When applied in harsh environments such as underwater, it reduces the difficulty of use for the user.

[0044] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
