Manual Quick-Release Connector for Camera Equipment

The problem

Photographers and videographers frequently move cameras between tripods, gimbals, sliders, and cages during a single shoot. Traditional mounting relies on threaded screws, which take time to align and tighten, especially when wearing gloves or working in tight spaces. Over repeated use, screw threads wear out, and cross-threading can damage expensive equipment plates. Some existing quick-release systems rely on complex lever mechanisms or proprietary shapes that restrict compatibility across different support brands. Users need a mechanical connection that locks securely by hand, releases predictably, and avoids loose parts that can be dropped on set.

The solution

This design solves the issue with a purely mechanical locking device (100) and a detachable connecting piece (1).

1. The fixed seat (2) acts as the stationary base, featuring clearance notches (26) on its walls to let the protrusions pass through.
2. Inside the seat, a driving member (3) rotates between a locking position and a release position. Its inner wall contains a first groove (31) at the lower end and an axially penetrating second groove (32), which communicate with each other. A limiting part (33) sits at the upper end of the first groove.
3. A locking member (4) is placed inside the driving member. It consists of a first elastic piece (41) and a positioning piece (42) resting against its upper end.
4. The connecting piece (1) has a limit protrusion (11) on its side wall. When pressed down, the protrusion enters the grooves.
5. A locking spring (5) is arranged circumferentially between the driving member and the fixed seat. It stores elastic energy to drive the rotation when the piece is pressed.
6. To release, a button device pushes a toggle block (35) on the driving member’s outer wall, rotating it until the positioning piece (42) wedges between the fixed seat and the driving member, keeping the second groove aligned so the piece lifts straight out.

Who it is for

• Camera accessory brands looking to offer a tool-free mounting plate system for their tripods, cages, or rigs without licensing proprietary profiles.
• Gimbal and stabilizer manufacturers needing a fast, repeatable way for operators to balance and swap cameras between handheld and mounted setups.
• Wholesalers and Amazon sellers sourcing reliable mechanical quick-release adapters for photography enthusiasts who want to upgrade from basic screw mounts.
• Broadcast and studio equipment integrators requiring standardized, durable connection points for moving heavy camera bodies between pedestals and jibs safely.

How it works

The main parts

Operating steps

1. Insertion: Align the connecting piece (1) over the fixed seat (2). The limit protrusions (11) pass through the clearance notches (26) and enter the second grooves (32).
2. Locking: Press the piece downward. The first elastic piece (41) compresses, and the downward force causes the locking spring (5) to rotate the driving member (3). The limit protrusion slides from the second groove into the first groove (31) and catches under the limiting part (33). The driving member stays in this locking position.
3. Releasing: Press the side button. The button pushes the toggle block (35), overcoming the locking spring’s tension and rotating the driving member back. The positioning piece (42) snaps partially between the fixed seat and the driving member, holding the release position open. The limit protrusion is now free in the second groove, allowing the connecting piece to be lifted straight out.

Applications

Tripod and monopod heads

Videographers switching between wide and telephoto lenses often swap entire camera bodies rather than changing glass. This connector allows the operator to press the button, lift the camera, and drop a second one onto the same tripod head instantly. The limit protrusions and matching inclined slopes ensure the plate settles exactly in the center.

Gimbal balancing

Balancing a motorized gimbal requires repeatedly removing and reattaching the camera to adjust the center of gravity. Threaded plates slow this down. With this push-to-lock design, the user drops the connecting piece into the gimbal’s receiver, letting the spring snap it shut, making micro-adjustments much faster.

Studio slider and dolly rigs

Moving a camera from a static tripod to a moving slider involves handling heavy gear over rails. A secure mechanical lock prevents accidental drops if the rig tilts. The circumferential locking spring maintains constant pressure on the driving member, keeping the limit protrusion firmly seated in the first groove even when the slider changes direction abruptly.

Broadcast pedestal mounts

Studio cameras on pneumatic pedestals are moved between sets daily. Operators need a connection that does not rely on fine motor skills to thread a screw while managing cables. The large button device and tactile click of the positioning piece wedging into place provide clear feedback that the mount is either fully locked or fully released.

Where it is less suitable

• Extreme underwater housings: The open clearance notches and sliding grooves could allow water or sand ingress unless heavily sealed in a custom housing design.
• Ultra-micro camera setups: The mechanical components, including the springs and driving member, require a minimum physical footprint, making them too bulky for very small action cameras without scaling down the entire mechanism.
