Description

A kind of bicycle folding box

Technical field

The utility model relates to bicycle field, specifically, relates to a kind of bicycle folding box.

Background technology

Along with function of bicycle constantly increases, people are for happy and healthy pursuit of riding, and more and more people can select folding bicycle as motion, the health instrument of riding.Folded bicycle, because volume after folding is little, is doted on by people, and in transportation, a lot of facilities are brought to customer in the aspects such as storage.Folded box tends to directly affect the service life of Folding Bicycle as the quality of its structure of core component of Folding Bicycle.Existing fold mechanism, reasonable structure and use outward appearance are not quite reasonable.In use, there is inconvenient, uneasy congruent factor.

Utility model content

The purpose of this utility model is to provide a kind of bicycle folding box, and bicycle folding box provided by the utility model is simple to operate, and locking mode is firm.

To achieve these goals, bicycle folding box provided by the utility model comprises protecgulum, bonnet, handle, lock dog, push rod, and mat piece, described protecgulum and described bonnet side are respectively arranged with and coordinate the keyway sliding with described lock dog both sides, bottom is respectively arranged with the lug boss cooperatively interacting with the interlock of described lock dog bottom notch portion, described lock dog and described push rod one end are fixedly linked, described handle is fixed in the rotating shaft of described push rod top by vertical connecting, described handle fixed end is eccentric wheel, described mat piece is arranged between described push rod and described eccentric wheel.

Described lock dog inside is provided with the elastomeric element that makes described lock dog return.

Described elastomeric element can be spring.

Described elastomeric element is at least two.

Described push rod is adjustable push rod spring.

Described mat piece can be leather sheath.

Bicycle folding box provided by the utility model, controls folding by handle, more convenient to operate.The locking mode that lock dog depressed part and protecgulum, bonnet lug boss coordinate, makes locking mode more firm, and parts are more durable.Bicycle folding box provided by the utility model have simple operation, safety firmly, the feature such as long service life.

Accompanying drawing explanation

Fig. 1 is cross-sectional view under bicycle folding box locking state described in the utility model.

Fig. 2 is cross-sectional view under bicycle folding box released state described in the utility model.

The specific embodiment

Below with reference to accompanying drawing, embodiment of the present utility model is described.The element of describing in an accompanying drawing of the present utility model or a kind of embodiment and feature can combine with element and feature shown in one or more other accompanying drawings or embodiment.It should be noted that for purposes of clarity, in accompanying drawing and explanation, omitted and the utility model expression and description irrelevant, parts known to persons of ordinary skill in the art or processing.

Below in conjunction with accompanying drawing, the utility model is described further.

As Fig. 1, shown in Fig. 2, bicycle folding box provided by the utility model comprises protecgulum 1, bonnet 2, handle 3, lock dog 4, push rod 5, with mat piece 6, described protecgulum 1 and described bonnet 2 sides are respectively arranged with and coordinate the keyway sliding with described lock dog 4 both sides, bottom is respectively arranged with the lug boss cooperatively interacting with the interlock of described lock dog 4 bottom notch portions, described lock dog 4 is fixedly linked with described push rod 5 one end, described handle 3 is fixing in the rotating shaft 9 of described push rod 5 tops by vertical connecting, described handle 3 fixed ends are eccentric wheel, described mat piece 6 is arranged between described push rod 5 and described eccentric wheel.Lock dog 4 inside are provided with two springs that make described lock dog return, and push rod 5 is adjustable push rod spring, and mat piece 6 is leather sheath.

When bicycle folding box completes locking state, as shown in Figure 1, the eccentric wheel of handle 3 passes through leather sheath 6 to lower compression push rod spring 5, push rod spring 5 drives lock dog 4 to move downward along keyway, until the depressed part of lock dog 4 coordinates the lug boss interlock forming with protecgulum 1, bonnet 2, regulate push rod spring 5 can control the elasticity of locking state.

When bicycle folding box completes released state, as shown in Figure 2, turning handle 3 is opened eccentric wheel, lock dog 4 makes lock dog 4 get back to initial position by two spring automatic reboundings of inside, until the depressed part of lock dog 4 coordinates the lug boss forming completely separated with protecgulum 1, bonnet 2, released state completes.

This bicycle folding box is controlled folding by handle, the push rod spring of being open to the custom regulates locking elasticity, more convenient to operate, the locking mode of lock dog depressed part and protecgulum, the interlock of bonnet lug boss, make locking mode more firm, parts are more durable, have simple operation, safety firmly, the feature such as long service life.

Although described the utility model and advantage thereof in detail, be to be understood that in the situation that do not exceed the spirit and scope of the present utility model that limited by appended claim and can carry out various changes, alternative and conversion.And the application's scope is not limited only to the specific embodiment of the described process of specification sheets, equipment, means, method and step.One of ordinary skilled in the art will readily appreciate that from disclosure of the present utility model, according to the utility model, can use and carries out with the essentially identical function of corresponding embodiment described herein or obtain process, equipment, means, method or step result essentially identical with it, that existing and will be developed future.Therefore, appended claim is intended to comprise such process, equipment, means, method or step in their scope.
