Abstract

The utility model discloses a locking device from rapping bar swing arm, including mount pad and swing arm, the one end of swing arm is provided with the cam, and the cam is equipped with two, two the cam is located the both sides of mount pad, it has the pivot of same root to run through between mount pad and two cams, the axle cap has been cup jointed through the screw thread to the one end of pivot, be provided with domaticly on the mount pad. The utility model discloses the whole process that the swing arm was opened in user's rotation can feel the damping and feel constantly the reinforcing, and reverse rotation swing arm can not receive the obstruction when accomodating, accomodates easily swiftly, compares traditional structure and has reduced manufacturing cost.

Description

Locking device from rapping bar swing arm

Technical Field

The utility model relates to a from rapping bar technical field especially relates to a locking device from rapping bar swing arm.

Background

The self-timer rod is a popular world self-timer device, can be randomly stretched and contracted between the length of 20 cm to 120 cm, and a user only needs to fix a mobile phone or a fool camera on a telescopic rod and can realize multi-angle self-timer through a remote controller. We all know that traditional rotary device's locking structure is realized through the frictional force between mount pad and the swing arm, through the frictional force between the adjustable mount pad of the bolt of screwing and the swing arm, realizes locking after rotatory different angles, and it is inconvenient to comparatively labouring and adjust during accomodating, to this problem, we provide a locking device from rapping bar swing arm.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the shortcoming that exists among the prior art, and the locking device who proposes from rapping bar swing arm.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a locking device from rapping bar swing arm, includes mount pad and swing arm, the one end of swing arm is provided with the cam, and the cam is equipped with two, two the cam is located the both sides of mount pad, it has the pivot of same root to run through between mount pad and two cams, the one end of pivot has cup jointed the axle cap through the screw thread, be provided with domaticly on the mount pad.

Preferably, a knob is fixed at one end of the rotating shaft, which is far away from the shaft cap.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses in when accomodating, the clearance between the domatic on cam on the swing arm and the mount pad is the biggest, the clearance can be along with opening of swing arm and rotate can diminish gradually, until cam and domatic contact, the swing arm continues to rotate, the cam can extrude domaticly, make the frictional force between cam and domaticly can continuously increase, can not continue to rotate under domatic blockking until the swing arm, the user rotates the whole process of opening the swing arm and can feel the damping and feel constantly reinforcing, reverse rotation swing arm can not receive the obstruction when accomodating, accomodate easily swiftly, compare traditional structure and reduced manufacturing cost.

Drawings

Fig. 1 is a schematic structural view of a locking device for a swing arm of a selfie stick according to the present invention;

fig. 2 is an exploded view of the locking device of the swing arm of the selfie stick according to the present invention;

figure 3 is adopting the utility model discloses a from rapping bar's structural schematic diagram.

In the figure: 1 mounting seat, 2 axle caps, 3 swing arms, 4 rotating shafts, 5 cams and 6 slope surfaces.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-3, a locking device from rapping bar swing arm, includes mount pad 1 and swing arm 3, and the one end of swing arm 3 is provided with cam 5, and cam 5 is equipped with two, and two cams 5 are located the both sides of mount pad 1, and it has same root pivot 4 to run through between mount pad 1 and two cams 5, and the one end of pivot 4 has cup jointed axle cap 2 through the screw thread, is provided with domatic 6 on the mount pad 1.

Wherein, a knob is fixed on one end of the rotating shaft 4 far away from the shaft cap 2.

The working principle is as follows: when accomodating, 5 the biggest in clearance between the domatic 6 on cam 5 on the swing arm 3 and the mount pad 1, the clearance can be along with the swing arm 3 open the rotation can diminish gradually, until cam 5 and domatic 6 contact, swing arm 3 continues to rotate, cam 5 can extrude domatic 6, make cam 5 and domatic 6 between frictional force can continuously increase, can not continue to rotate under domatic 6 blockking up until swing arm 3, the user rotates the whole process of opening swing arm 3 and can feel the damping and feel constantly reinforcing, reverse rotation swing arm 3 can not receive the obstruction during accomodating, it is light swift to accomodate, compare traditional structure and reduced manufacturing cost.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
