Bicycle Work Stand Clamp With Quick-Release Latching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle work stands lack a mechanism for quick adjustment of the clamping space, relying on a threaded structure of a pull rod that is inefficient for rapid clamping adjustments.
Innovation Solution
A bicycle work stand with a latching mechanism featuring a fixed clamp, movable clamp, screw rod, and rotating handle, allowing for quick opening and closing of the clamping head through a combination of threaded engagement and manual disengagement via a pressing button and linkage system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a threaded structure of a pull rod is used to adjust the clamping space, then the clamping mechanism can be securely locked, but the adjustment speed is slow and inefficient
Solution Approach 1:
The patent applies a dynamic adjustment mechanism where the clamping head can quickly transition between different clamping positions using a movable clamp guided by guide rails. This allows the system to switch between locked and adjusted states dynamically, resolving the contradiction between secure locking and fast adjustment by separating the locking function (threaded pull rod) from the adjustment function (movable clamp with guide rails).
Solution Approach 2:
The clamping mechanism is segmented into distinct functional components: a fixed clamp for positioning, a movable clamp for adjustment, and a threaded pull rod for locking. This segmentation allows each component to perform its specialized function efficiently - the movable clamp provides quick positioning while the threaded pull rod provides secure locking, thereby resolving the contradiction between adjustment speed and clamping security.
2Manufacturing precision
If a threaded structure is used for clamping adjustment, then precise positioning can be achieved, but the operation complexity increases
Solution Approach 1:
The patent introduces guide rails as an intermediary mechanism between the movable clamp and the fixed clamp. These guide rails provide precise alignment and positioning guidance, ensuring accurate clamping position without requiring complex threading operations. The guide rails mediate the movement of the movable clamp, achieving precise positioning while simplifying the operation to a straightforward sliding motion.
3Ease of operation
If the clamping head structure is simplified for ease of use, then the adjustment mechanism becomes less reliable
Solution Approach 1:
The patent merges multiple reliable mechanisms into a unified clamping system: the movable clamp combines with guide rails for precise guidance, the threaded pull rod provides secure locking, and the fixed clamp ensures stable positioning. This combination of multiple simple but reliable components achieves both ease of operation and high reliability, as each component is simple in itself but their integration creates a robust system.

Function Achieved in This Case
Enables rapid and efficient clamping and release of bicycle components, enhancing user convenience and efficiency during maintenance tasks.
Implementation Method 1
When the pressing button is in the released position, the threaded portion engages the screw rod
Implementation Method 2
One end of the elastic member is inserted into the insertion hole and abuts against the stopper member, and the other end of the elastic member abuts against the latching block

AI summary
A bicycle work stand includes a leg support and a clamping head. The leg support consists of an upright rod and a base. The clamping head includes a fixed clamp, an extension rod, a movable clamp, a screw rod, and a latching mechanism. The screw rod is pivotally connected to the fixed clamp at one end and to a rotating handle at the other. The movable clamp is sleeved on the screw rod. The latching mechanism includes a pressing button, a linkage rod, and a latching assembly with a threaded portion. The pressing button allows the threaded portion to engage or disengage the screw rod, controlling the movable clamp.
