Description

Sleeve-type shaft with pause function

technical field

The utility model relates to a socket-type rotating shaft, in particular to a socket-type rotating shaft with a pause function.

Background technique

Consumer electronic products with a flip cover, such as portable computers, electronic dictionaries, portable audio-visual playback devices, and flip-top mobile phones, etc., generally place the main body in the lower half, and connect the shaft and the upper half. The cover part of the body part is connected so that the cover part can be opened and closed relative to the main part. Therefore, the rotating shaft is also a major factor in determining the quality of the above-mentioned products.

However, for the aforementioned 3C electronic products, in order to avoid the items connected to the cover, such as a liquid crystal display, when the cover is closed to the main body, if there is no buffer mechanism, the cover will directly hit the main body, which may damage the Expensive LCD monitors. The traditional solution is to provide elastic buffer pads between the cover body and the main body. Although these buffer pads can absorb the impact force when the cover is closed, the setting of these buffer pads makes the cover body It cannot be in close contact with the main body when it is closed, so at least one sliding or push switch must be provided between the two, so that when the cover is closed, the two can be tightly connected by the switch and the cushion pads can be compressed. It is conceivable that since the cushion pads utilize their own elasticity to absorb the impact force, repeated compression will often cause the elasticity of the cushion pads to become fatigued and gradually lose the cushioning effect.

Therefore, related companies set a buffer mechanism on the rotating shaft, which is mainly used to set at least a pair of convex points and grooves between a fixed component and a rotating component that the shaft of the tandem (axial friction) rotating shaft passes through. , so that when the cover body rotates toward the main body, the pair of protrusions snap into the corresponding grooves to form a buckling phenomenon, thereby producing a buffering function. If it is desired to closely connect the cover body and the main body, it is only necessary to apply an external force to the cover body to separate the protrusion from the groove. Although the traditional tandem shaft can achieve the cushioning function by adding additional fixed components and rotating components, this type of shaft has many components, such as a bracket, a shaft, at least one elastic component, a washer, and an end seal , plus a fixed component and a rotating component, etc., not only increase the complexity of the assembly, but also increase the manufacturing cost, which is not economical.

The traditional socket-type rotating shaft uses the socket of the male and female components to make the radial friction formed between them to produce the effect of stagnant positioning. Since the sleeve-type rotating shaft cannot be additionally provided with a rotating assembly and a fixing assembly respectively having convex points and grooves in the axial direction, it is difficult to provide a cushioning function when closing, and it is urgently needed to be improved by the industry.

Detailed ways

As shown in Figures 1 to 3, basically, the sleeve-type rotating shaft of the present invention is composed of a fixed part 1 and a movable part 2, wherein the "movable" and "fixed" do not limit the above two As for the action state of the components, during implementation, the movable part 2 can also maintain a fixed state, but the relative rotation action is generated by the fixed part 1 .

Wherein, the fixing part 1 is a rod body, and one end of the connecting part 11 is connected to an article, such as a main body, such as a main body. On an article, but not limited to this, when the connecting portion 11 is implemented, as mentioned above, it can also be a single or double milled cylinder, a triangular column, a square column... and other polygonal cylinders to obtain non-destructive Locked embedded positioning effect.

The other end of the connecting portion 11 is provided with a sleeve 12 , and a shaft hole 121 is axially opened inside it. As shown in the figure, an arc edge 122 is recessed around the circumference of the shaft hole 121 . Furthermore, the rear section of the shaft hole 121 communicates with a stepped hole 123 with a larger diameter (shown in FIG. 3 ).

The movable part 2 is also a rod body, and its connecting part 21 at one end is connected to another article, such as a cover part, such as a liquid crystal display. It is fixed on an article, but it is not limited to this. When the connecting part 21 is implemented, as mentioned above, it can also be a single or double milled cylinder, a triangular column, a square column... and other polygonal cylinders to obtain Non-locking embedded positioning effect.

Wherein, a collar 22 is provided on the inner side of the connecting portion 21, which is used as abutment when it is socketed with the fixing member 1. The collar 22 extends a shaft column 23 laterally, which depends on the number of the arc edges 122. For example, a corresponding number of cutting grooves 233 is opened in one axial direction, and divided into two column arcs 231, and each side of each column arc 231 is adjacent to a flat surface 232, as shown in the figure, the opposite flat surfaces 232 are divided by cutting grooves 233 , so as to provide the axle column 23 with moderate elasticity. In addition, the free end of the shaft post 23 is provided with a flange portion 234 corresponding to the size of the stepped hole 122, and a post hole 235 (shown in FIG. Lubricating grease is placed so that it can pass through the cut groove 233 to form a lubricating effect. In addition, at least one oil groove 236 is defined on the surface of the two column arcs 231 for accommodating lubricating grease.

Therefore, the diameter between the two arcs 231 of the shaft 23 is slightly larger than the inner diameter of the shaft hole 121. Therefore, as shown in FIGS. The outer surface interferes with the inner wall of the shaft hole 121 to produce a stagnant positioning effect, and the flange portion 234 forms a buckled state with the stepped hole 123 so that the movable part 2 and the fixed part 1 cannot be axially separated.

Please refer to Fig. 4 and Fig. 5, which are cross-sectional views of the shaft column 23 rotating in the shaft hole 121. When the cover body is about to be closed and rotates clockwise, it will drive the shaft column 23 to rotate synchronously, and when a column arc 231 moves to the position of the arc edge 122 of the shaft hole 121, that is, it falls in due to elastic expansion, thus producing a stuttering phenomenon as shown in FIG. 5 and stopping the rotation. If the cover is to be closed to the main body, an external force is continuously applied to the cover, so that the post arc 231 is separated from the arc edge 122, and interferes with the inner wall of the shaft hole 121 again until it is attached to the main body.

Please refer to FIG. 6 , which is a schematic diagram of another embodiment of the socket-type rotating shaft of the present invention. The difference from the previous embodiment is that an arc 122 is recessed around the shaft hole 121 of the sleeve 12 . The arc diameter is larger than the column arc 231 of the shaft column 23 . As shown in Figure 7, when the cover body is about to be closed and rotates clockwise, it will drive the shaft 23 to rotate synchronously, and when a column arc 231 moves to the position of the arc edge 122 of the shaft hole 121, it will expand due to elastic expansion. Falling into, forming a pause phenomenon. Since the arc diameter of the arc edge 122 is larger than that of the column arc 231, the column arc 231 can continue to move for a certain distance on the arc edge 122, thereby producing a two-stage torque change. To close the cover to the main body, Then continue to apply external force to the cover body, so that the column arc 231 is separated from the arc edge 122, and interferes with the inner wall of the shaft hole 121 again until it is attached to the body portion.

Therefore, through the implementation of the utility model, it makes the sleeve-type rotating shaft structure have a pause function, so that the covering between the two items can also achieve a cushioning effect, which is compared with the known ones with convex points and grooves. In terms of the tandem shaft structure of the rotating component and the fixed component, not only the number of components is greatly reduced, but also only the shaft column of the movable part needs to be inserted into the shaft hole of the fixed part in assembly, thereby reducing the tedious assembly of components . Furthermore, the arc radius of the arc recessed around the shaft hole of the sleeve is larger than the arc of the shaft, so that when the two form a pause, the arc can continue to move for a certain distance on the arc, thereby producing a two-stage The change in torque is a masterpiece that has never been seen in similar items.

What the utility model discloses is a kind of preferred embodiment, and all partial changes or modifications originating from the technical thought of the utility model and easily deduced by those familiar with the technology are all within the scope of the utility model. scope of patent rights.
