Description
Technical field
The present invention relates to a kind of double-degree-of-freedom rotating shaft bracket, particularly relate to a kind of double-degree-of-freedom rotating shaft bracket with locating function.
Background technique
The rotating shaft that has hinge function in daily life is seen everywhere, and from electronic goods such as notebook computer, TV, display device, Wenquxings, until electrical home appliances such as microwave ovens, refrigerator, even furniture such as wardrobes, desk, all can see the figure of rotating shaft.
The effect of rotating shaft mainly is that the member of two separation is hinged, make a member relatively another member relatively rotate, to change relative position and the angle between two members.Traditional rotating shaft has only a shaft axis, and two members can only rotate on the one degree of freedom direction.Along with the continuous development of science and technology, people are more and more higher to the requirement of product, according to the requirement of different device, when the design rotating shaft, make rotating shaft have two rotations on the degrees of freedom direction.Rotation on two degrees of freedom directions, i.e. rotating shaft has two shaft axiss, and two members can be that center of rotation is rotated with these two shaft axiss respectively.
When the design rotating shaft, make rotating shaft have locating function.So-called locating function is meant when rotating shaft is subjected to a certain size external force, can rotate along with this external force, adjusts the position and the angle of institute's connector element with this.But when not being subjected to external force, rotating shaft is to be maintained fixed, and makes the position and the angle of institute's connector element constant.Reach the purpose of this location, prior art has many kinds of design method.One of them is to add one group of symmetry ring plate in the rotating shaft design.This organizes symmetrical ring plate and comprises that one has the ring plate that ring-type is equidistantly arranged convex body, and a ring plate with respective slot.When rotating shaft was not stressed, convex body all was sticked among the respective slot, so that the function of location to be provided.When rotating shaft was subjected to an external force, then convex body skidded off corresponding groove, rotated and snap into the groove of desired location.
Another kind of rotating shaft design is to add one or more friction pads in rotating shaft.By the mutual frictional force of friction pads, perhaps the frictional force between friction pads and the positioning shaft device provides required locating function.
On reality is used, can use an above-mentioned rotating shaft with locating function, want hinged member to connect.So make hinged member when not being subjected to external force, can keep relative invariant position.But only use a rotating shaft, tend to, and cause rocking and instability when rotating because have only a rotating fulcrum.
For reaching the purpose of balance, generally all use the rotating shaft that has locating function more than two, want hinged member to connect.This mode can make member have plural rotating fulcrum, the balance when rotating with maintenance when rotating.But use the rotating shaft that has locating function more than two, often cause the increase of cost of production, and the product assembling is prolonged man-hour.
Summary of the invention
In order to overcome the deficiencies in the prior art, the object of the present invention is to provide the rotation of a kind of rotating shaft on dual free dimension, can take into account again and save cost and rotating shaft locating function, the balance in the time of also keeping the rotating shaft rotation simultaneously.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of double-degree-of-freedom rotating shaft bracket with locating function, it comprises support device, the support device both sides are hinged with the left and right supporting frame that connects first member by the left and right positioning shaft of shaft axis unanimity respectively, described support means bottom portion is hinged with the supporting frame that connects second member by positioning shaft, described right positioning shaft end is provided with positive stop lug boss, on the described right positioning shaft respectively cross-under spring, right supporting frame, axle sleeve and locking nut are arranged, locking nut is set with handle outward;
As a modification of the embodiment above, described left positioning shaft end is provided with positive stop lug boss, on the described left positioning shaft respectively cross-under axle sleeve, left supporting frame, resilient pad and locking nut are arranged.
As the further improvement to above-mentioned mode of execution, described positioning shaft is cross-under nut, supporting frame, spring, axle sleeve and locking nut respectively, and described locking nut is set with handle outward.
The invention has the beneficial effects as follows: this product guarantees the rotation that first member and second member can carry out on dual free dimension, and the while has been adopted the simple positioning shaft position structure of structure, make first member be stationary state, install thereby can be widely used in the hinged of electronic product, electrical appliance and furniture with respect to second member.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention.
Embodiment
With reference to Fig. 1, a kind of double-degree-of-freedom rotating shaft bracket with locating function, it comprises support device 1, support device 1 both sides are passed through the left side of shaft axis unanimity respectively, right positioning shaft 21,22 are hinged with a left side that connects first member, right supporting frame 31,32, described support device 1 bottom is hinged with the supporting frame 5 that connects second member by positioning shaft 4, support frame as described above 5 is provided with the mounting hole 51 that connects second member, a described left side, right supporting frame 31,32 are provided with the mounting hole 311 that connects first member, 321, described mounting hole 321 is a slotted hole, this is designed for a fine setting left side, right supporting frame 31, mounting distance between 32, avoid because of a left side, right supporting frame 31, mounting distance tension between 32, and cause the distortion of the first member tension.Certainly according to the installation needs of reality, first member, second member are not limited to adopt the Connecting format of mounting hole, also can adopt other mounting structures commonly used.
This product is in order to reach the required locating function of rotary shaft rack, and described left positioning shaft 21 ends are provided with positive stop lug boss, on the described left positioning shaft 21 respectively cross-under axle sleeve 211, left supporting frame 31, resilient pad 212 and locking nut 213 are arranged.Axle sleeve 211 is used to adjust the distance of left supporting frame 31 and the level of support device 1; A left side is coated with a resilient pad 212 on the positioning shaft 21 at least, realizes locating function by mutual frictional force of resilient pad 212 and the frictional force between resilient pad 212 and the left supporting frame 31.
