Description

A kind of quick-locking mechanism of scooter expansion link

Technical field

Scooter manufacturing technology field is the utility model is related to, more particularly to a kind of quick locking machine of scooter expansion link Structure.

Background technology

For the telescopic sleeving rod of scooter as common connector, the structure of conventional telescopic bar is by multiple different-diameters The blank pipe body of rod is sequentially socketed to form, and the hollow tube body of rod of variant diameter, its one end is provided with opening, is available for the inner sleeve body of rod to make unidirectional Stretch out or Retraction, in general expansion link due to the self-locking mechanism of its own due to itself and cause provide clamping force not Enough, because the pressure born is larger in stage is built, therefore stage collapses caused by the fixation loosely of inner sleeve bar often occurs Collapse phenomenon.Existing locking device need with torque arm it is locked, operate inconvenience, and adjustability is poor, and process is comparatively laborious, It is not easy to operate.

Utility model content

For overcome the deficiencies in the prior art, the utility model provides a kind of quick locking machine of scooter expansion link Structure, utility model is simple in construction, easily operated, and high safety.

To achieve these goals, the utility model adopts the following technical scheme that：

A kind of quick-locking mechanism of scooter expansion link, including the first lock mouth and the second lock mouth, the described first lock mouth For tube-in-tube structure, first lock mouth one end is provided with internal thread, and the other end forms claw by offering multiple breach vertically；Institute The the second lock muzzle stated is located on the first lock mouth and compresses claw, and the second lock mouth is threadedly coupled with the first lock mouth.Described first The internal thread for locking mouth is reversely opposite with the internal thread of the second lock mouth.

In use, the first described lock mouth is connected with loop bar end thread, Handle fitting, the first lock mouth are provided with loop bar Claw be enclosed on Handle fitting periphery, the second lock mouth is threadedly coupled through Handle fitting and with the first lock mouth；Second lock mouth and the One lock mouth realizes the locking of loop bar and Handle fitting after screwing.

The claw of the first described lock mouth is flexible, and the diameter of recess under nature between claw is less than the straight of loop bar Footpath.

Described second lock mouth is radially inside provided with multiple floors, and the spatial form between floor locks mouth with first Outer shape match.

Compared with prior art, the utility model has advantages below：

The utility model by first lock mouth and second lock mouth combined joint, be fixed two interconnection stretch Contracting bar, the first lock mouth is tube-in-tube structure, and thin expansion link can be fixed by forming claw provided with multiple breach；Second lock muzzle is set On the first lock mouth and compressing claw is locked custom.Compared with prior art, the utility model is simple in construction, is easy to grasp Make, and high safety.

Brief description of the drawings

Fig. 2 is the assembling figure of quick-locking mechanism.

In figure, 1, loop bar；2nd, Handle fitting；3rd, the first lock mouth；4th, the second lock mouth.

Embodiment

Structural principle of the present utility model and operation principle are described in further detail below in conjunction with the accompanying drawings.

As shown in figure 1, a kind of quick-locking mechanism of scooter expansion link of the utility model includes the first lock mouth 3 and second Mouth 4 is locked, the described first lock mouth 3 is tube-in-tube structure, and first lock mouth 3 one end is provided with internal thread, and the other end by opening vertically Claw is formed provided with multiple breach；Described second lock mouth 4 is set on the first lock mouth 3 and compresses claw, the second lock mouth 4 and the One lock mouth 3 is threadedly coupled.

The claw of first lock mouth 3 is flexible, and the diameter of recess under nature between claw is less than the diameter of loop bar 1. The internal thread of first lock mouth 3 is reversely opposite with the internal thread of the second lock mouth 4.Radially inside being provided with for second lock mouth 4 is multiple Floor, the outer shape of spatial form and the first lock mouth 3 between floor match.

As shown in Fig. 2 in use, described first lock mouth 3 is connected with the end thread of loop bar 1, handle is provided with loop bar 1 Hand accessory 2, the claw of the first lock mouth 3 are enclosed on the periphery of Handle fitting 2, and the second lock mouth 4 locks mouth 3 through Handle fitting 2 and with first Threaded connection；Second lock mouth 4 and first locks the locking that loop bar 1 and Handle fitting 2 are realized after mouth 3 screws.

Operation principle of the present utility model is：There is clearance position the inside of second lock mouth 4, can be shunk using the first lock mouth 3 Feature（First lock mouth 3 has opened individual breach, can reach and easily expand and tighten）Make the first lock mouth 3 and the second lock mouth 4 in spiral shell It will not fall off under the situation that line is all back-outed.Advantage of this is that accessory will not be lost.It is quick using the lock mouth 4 of rotation second Locking loop bar position, so as to reach conveniently regulative mode 2. first lock mouth 3 and second lock mouth 4 have assembling after not The design that can be come off.
