Description

Quick release handle positioning structure

This creation is a technical field related to the positioning structure of a quick-release handle, in particular, a quick-release handle can be firmly coupled to one end of a shaft, and the quick-release can only be applied when a sufficiently large pulling force is applied outwardly The handle is detached from the shaft, thereby making it a quick-release handle positioning structure with better practicality and convenience.

Generally, the front and rear wheels of the bicycle and the front and rear forks are each combined with a shaft, and in order to facilitate the application of force to tighten or relax the shaft, it is usually tied to one end of the shaft A quick-release handle is combined so that the user can quickly combine or detach the front and rear wheels with the front and rear forks.

Generally, the coupling structure of the conventional quick-release handle is fixed. As shown in the Taiwan Patent No. I500533, it mainly uses a coupling bolt to fix the quick-release handle screw lock to one end of the shaft. Locking and disassembling are time-consuming and laborious, so once the screw lock is combined, it will not be removed anymore, so the two shafts worn at the front and rear wheels will be combined with a quick release handle, and this is the case. Not only will it increase costs, but also take up more space.

In addition, in order to solve the above problems, some manufacturers have developed a magnetic quick-release handle combination structure, as shown in Taiwan Patent No. M544459, its main A first attachment element and a second attachment element that can magnetically attract each other are provided on one end of the shaft and the quick release handle, respectively, by the magnetic properties of the first attachment element and the second attachment element The suction action allows the quick-release handle to be attracted to one end of the shaft, and when a pull force is applied to the quick-release handle outward to overcome the magnetic force of attraction, the quick-release handle can be removed from the shaft One end detached. In this way, the two shafts worn on the front and rear wheels can share a quick release handle, so as to further reduce the cost and take up less space. However, the conventional magnetic quick release handle has the problem that it is easily disengaged from the shaft due to vibration during riding.

In view of this, the creator is in-depth conceived for the above problems, and actively research and improve the trial to develop and design the creation.

The main purpose of this creation is to solve the high cost and space occupied by the traditional fixed quick-release handle structure, and the conventional magnetic quick-release handle structure that is easy to detach due to vibration when riding and so on. problem.

The positioning structure of the quick-release handle described in this creation includes a shaft, an elastic tight ligand, a quick-release handle and a connecting rod. Wherein, the two ends of the shaft respectively have a screwed end and a driving end, and the end face of the driving end has a connecting hole, and the connecting hole includes a driving section and a first accommodating section arranged in sequence from outside to inside The driving section is polygonal, and the first accommodating section has a larger inner diameter. The elastic tight fitting system is barrel-shaped and has elastic expansion capability. The elastic tight fitting body is embedded in the first accommodating section and has an inner diameter slightly smaller than the driving section. The quick release handle has a driving part and a handle part extending from one side of the driving part. One end of the connecting rod is connected to the driving part, the other end A connecting segment extends outwardly to be inserted into the connecting hole. The connecting segment is a polygon corresponding to the driving segment. When the connecting segment is inserted into the first accommodating segment, the elastic tight fitting body will be supported by it Open to produce an elastic binding force.

The positioning structure of the quick release handle provided by this creation can enable the quick release handle to drive the shaft to rotate by pressing the connecting section of the connecting rod and the driving section of the connecting hole The purpose of relaxation. In particular, the elastic tight ligand provided in the connecting hole can generate an elastic restraining force on the connecting section of the connecting rod, so that even if an external force impacts during riding, the quick release handle can still be connected with the shaft Maintain a stable positioning relationship, and then achieve the purpose of improving structural stability and riding safety. Moreover, as long as the outward pulling force applied to the quick release handle is greater than the elastic binding force of the elastic tight ligand, the connecting rod can be detached from the connecting hole, so that the quick release handle is separated from the shaft, so the Has better practicality and convenience.
