Abstract

The utility model discloses a kind of lever automatic supporters, including bottom plate, the lower end two sides of the bottom plate are symmetrically arranged with rotating shaft core, the rotating shaft core is rotatably arranged in core seat, the core seat is arranged in output swing arm and inputs the junction of swing arm, the output swing arm and input swing arm are integrally formed setting, and the rotating shaft core is socketed with reduction torsion spring.The lever automatic supporter, structurally reasonable, practical, this lever automatic supporter, the lower pressure generated when mobile phone and other items is placed, is directly translated into chucking power by lever principle, principle is simple and efficient, at low cost, part is few, and production assembly is simple, and durable, failure rate is low.

Description

A kind of lever automatic supporter

Technical field

The utility model belongs to car, household, office and other places and is used to the equipment such as automatic clamping mobile phone, tablet computer A kind of or other articles, and in particular to lever automatic supporter.

Background technique

The products such as current mobile phone support, there is complicated drive mechanism in inside, at high cost, and production assembly is complicated, therefore Barrier rate is high.

Summary of the invention

It is mentioned above in the background art to solve the purpose of this utility model is to provide a kind of lever automatic supporter Problem.

To achieve the above object, the utility model provides the following technical solutions: a kind of lever automatic supporter, including bottom Plate, the lower end two sides of the bottom plate are symmetrically arranged with rotating shaft core, and the rotating shaft core is rotatably arranged in core seat, the axle center Seat is arranged in output swing arm and is integrally formed and is arranged with the junction of swing arm, the output swing arm and input swing arm is inputted, and described turn Axis axle center is socketed with reduction torsion spring.

Preferably, convex block is equipped on the upside of on the inside of the upper end of the output swing arm and inner end of input swing arm, and convex block Surface is equipped with anti-slip layer.

Preferably, the length of the output swing arm is greater than the length of input swing arm.

The technical effect and advantage of the utility model: the lever automatic supporter, structurally reasonable, practical, this lever Formula automatic supporter, the lower pressure generated when mobile phone and other items is placed are directly translated into chucking power, principle letter by lever principle Single and efficient, at low cost, part is few, and production assembly is simple, and durable, failure rate is low.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is the clamp position structural schematic diagram of the utility model；

Fig. 3 is the portion the A enlarged structure schematic diagram of the utility model.

In figure: 1 bottom plate, 2 output swing arms, 3 input swing arms, 4 core seats, 5 rotating shaft cores, 6 reduction torsion springs.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

The utility model provides a kind of lever automatic supporter as shown in Figs. 1-3, including bottom plate 1, the bottom plate 1 Lower end two sides are symmetrically arranged with rotating shaft core 5, and the rotating shaft core 5 is rotatably arranged in core seat 4, and the setting of core seat 4 exists It exports swing arm 2 and inputs the junction of swing arm 3, the output swing arm 2 and input swing arm 3 are integrally formed setting, the shaft axis The heart 5 is socketed with reduction torsion spring 6.

Specifically, being equipped with convex block, and convex block on the inside of the upper end of the output swing arm 2 and on the upside of the inner end of input swing arm 3 Surface be equipped with anti-slip layer, be easy to clamp, and increase frictional force, make to clamp stronger.

Specifically, it is described output swing arm 2 length be greater than input swing arm 3 length, allow export swing arm 2 be clamped in by The top of object is pressed from both sides, is clamped more stable.

The objects such as mobile phone are placed on bottom plate 1, bottom plate 1 is placed vertically and slightly tilted backwards, and the objects such as mobile phone are due to weight Power reason pushes input swing arm 3, and output swing arm 2 will clamp the objects such as mobile phone, and when mobile phone takes out, swing arm is in reduction torsion spring 6 The lower revolution of elastic force effect resets, and prepares for clamping next time.

Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic It is equivalently replaced, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on, It should be included within the scope of protection of this utility model.
