Abstract

The utility model provides an automatic flip-open device of motorcycle tail box lid convenient in use without any additional action, which comprises two steel pull springs with middle number of turns being 1 ring to 10 rings, wherein, one end of one pull spring is positioned on the root part of the superior lid of the tail box and the other end on the same-side inner wall of tail box body; the other pull spring is symmetrically positioned on the other side of the tail box; the diameter of each pull spring ranges within phi 3 mm to phi 25 mm and the applying linear diameter within phi 0.5 mm to phi 4 mm. Through adopting the above technology scheme, the utility model realizes automatic flip-open of box lid when user opens the motorcycle tail box; during production, the flip-open angle is adjustable within the parameter range in above technology scheme, bringing great convenience to user.

Description

Motor bike boot case lid automatically spring open device

Technical field:

The utility model relates to the motorcycle accessories technical field, refers in particular to a kind of device that automatically springs open of motor bike boot case lid.

Background technology:

Existing motor bike boot be by be connected between casing and the case lid simple and easy cotton rope control the angle that case lid is opened, the shortcoming that this kind structure exists is that cotton rope uses easy fracture after a period of time, easy tong during misoperation, when using, the user must raise loam cake with hand, could or put into case with the article taking-up, can not realize automatically springing open of boot.

Summary of the invention:

The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of easy to use, need not the device that automatically springs open that any additional move can realize that motor bike boot case lid opens automatically.

The technical scheme that provides for the utility model that achieves the above object is: this device is that the number of turns is the steel tension spring of 1～10 circle in the middle of two, wherein an end of a tension spring is installed in the root of boot loam cake, the other end is installed on the inwall of boot casing homonymy, another tension spring is installed in the opposite side of boot symmetrically, wherein the spring diameter of every tension spring uses the line footpath in Φ 0.5MM-Φ 4MM scope in Φ 3MM-Φ 25MM scope.

The utility model when the user opens the motor bike boot, can be realized automatically springing open of case lid by above technical scheme, and during production, the angle that flicks can make things convenient for the user dramatically according to adjusting in the described parameter area in the such scheme.

Description of drawings:

Fig. 1 is an example structure scheme drawing of the present utility model;

Fig. 2 is the mounting structure scheme drawing of the utility model embodiment.

The specific embodiment:

Referring to Fig. 1, shown in Figure 2, the number of turns is No. 65 manganese steel matter tension springs 1 and 2 of 3 circles in the middle of using two in the present embodiment, wherein an end of a tension spring 1 is by the root of dowel fixes at boot loam cake 3, the other end is fixed on the inwall of boot casing homonymy in the same way, another tension spring 2 is installed in the opposite side of boot symmetrically, wherein the spring diameter of every tension spring is Φ 12MM, and line directly is Φ 1.8MM.The angle that automatically springs open of boot loam cake is 80 degree.

The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection domain of the present utility model.

Claims

1, motor bike boot case lid automatically springs open device, it is characterized in that: this device is that the number of turns is the steel tension spring (1,2) of 1～10 circle in the middle of two, wherein an end of a tension spring (1) is installed in the root of boot loam cake (3), the other end is installed on the inwall of boot casing homonymy, another tension spring (2) is installed in the opposite side of boot symmetrically, wherein the spring diameter of every tension spring uses the line footpath in Φ 0.5MM-Φ 4MM scope in Φ 3MM-Φ 25MM scope.
