Description

2-position quick moving device

The present invention relates to an apparatus for relocating an object to one of two translational movement positions, and more particularly, to a two-position rapid switching apparatus that enables a positional change by a rapid and accurate translational movement with a small force.

The necessity of placing the object in one of the first and second positions on the translational path is such that the optical device shifts its position using the object as a lens to switch the magnification of the optical device to the first and second magnifications. In this case, the conventional apparatus has a threaded guide bar and a thread tab engaged with a thread of the guide bar integrally formed on an object, and a rotation lever causing a relative movement of the thread tab with respect to the thread. Rotate the rotary lever so that the object moves little by little from the first position to the second position, or vice versa, or by pushing the lever connected to the screw tab in a straight direction until the object moves to the desired position. It was a rescue.

However, in the case of the conventional two-position switching device having such a structure, it is difficult to quickly change the position from the first position to the second position or vice versa, and a mechanical error may be caused due to the thread tolerance. In addition, the wear caused by repeated operation could cause errors in the first position and the second position, and the object was correctly positioned in the first position or the second position as the operator turned the rotary lever less or pushed the lever less. In many cases, operation errors caused by operational mistakes are prevented. Therefore, an error due to repetitive operation or an operation error due to an operation mistake has been a problem in places requiring high precision, such as optical equipment, and there is a problem in that it does not sufficiently correspond to equipment requiring rapid operation or durability.

Accordingly, a technical object of the present invention devised by recognizing the problems of the prior art as described above is to provide a two-position quick switching device for quickly positioning an object from a first position to a second position or vice versa.

In addition, it is to provide a two-position quick switching device which does not cause an operation error due to an operator's mistake of operation.

In addition, it is to provide a two-position quick switching device that does not cause an error even after repeated operation.

Hereinafter, the present invention will be described in detail with reference to embodiments of the present invention shown in the accompanying drawings.

1 is a conceptual view showing a state in which the two-position quick switching device according to an embodiment of the present invention applied to the lens movement of the optical equipment, Figure 2 is an exploded perspective view of the elastic moving means used in the present invention. 3 is a view for explaining the operation of the elastic movement means used in the present invention, Figures 4 and 5 shows the state in which the object is in the first position and the second position.

As shown therein, the two-position quick switching device according to the present invention is an object that is selectively positioned at one of the first position (see FIG. 4) and the second position (see FIG. 5) of the fixture 1 in translational manner. (2) and applied to a two-position switching device including a guide member (3) installed in the fixture (1) to guide the movement of the object (2), wherein the fixture (1) and the object (2) In the meantime, in the case where the object 2 is moved from the current position to the opposite position, a force that resists the movement of the object 2 to a certain constant distance is applied, and when the threshold distance is reached, the object 2 is moved to move. An elastic moving means is provided which exerts an elastic force to apply the force to quickly position the object 2 in the desired opposite position.

As shown in Figures 1 and 2, the elastic movement means has a mount shaft 10, one end of which is fixed to the object (2), one end is coupled to the mount shaft 10 to be translationally and rotatable and the other end is Rotating lever 12 is rotatably coupled to the fixture 1 and provided with an elastic guide bar 11 between both ends, and one end is fixed to the fixture 1 and the other end is the elastic guide bar of the pivot lever 12. It can be configured to include an elastic body 13 is coupled to the translationally movable (11).

A groove 12a is formed on the rotation lever 12 side and a bearing inserted into the groove 12a on the outer circumference of the mount shaft 10 for translational and rotational coupling between the mount shaft 10 and the rotation lever 12. It is preferable that 10a is provided.

In order to mediate the coupling between the elastic body 13 and the fixture 1, it is preferable to have an elastic support 14 fixed to the fixture 1, and the elastic guide bar 11 by appropriately processing the end of the elastic body 13 ) May directly form a translatable coupling, it is also preferred that the above coupling is made via another elastic support (15).

The operation of the present invention will be described below.

The right centerline of the three centerlines shown in FIG. 3 represents the centerline of the elastic body 13 when the object 1 is in the first position shown in FIG. 4, and the left centerline represents the object 1 in FIG. 5. The centerline of the elastic body 13 in the state of being in the 2nd position shown to the centerline is shown in which the object 1 switches from a 1st position to a 2nd position, or from a 2nd position to a 1st position. The center line of the elastic body 13 is shown in a critical position.

As shown in FIG. 4, in the first position, the elastic support 15 connected through the elastic body 13 and the elastic guide bar 11 is positioned at one edge of the elastic guide bar 11, and the elastic body 13 is Tensile force is applied to maintain this state. In this state, when a force is applied toward the second position to move the object 2 to the second position, the mount shaft 10 having one end fixed to the object 2 is moved, and thus, the bearing 10a is mounted through the bearing 10a. The pivoting lever 12 associated with the shaft 10 gradually recovers from the state of FIG. 4 inclined toward the first position, eventually leading to the intermediate position of the first and second positions as shown in FIG. Come. In this process, the elastic body 13 applies a force that resists movement. In the critical position, the restoring force of the elastic body 13 is at a maximum state, and if a slight additional force is applied toward the second position, the restoring force of the elastic body 13 is quickly completed to move to the second position shown in FIG. Even when moving from the second position to the first position it is possible to move quickly by a similar process as above. The restoring force acting by the elastic body 13 causes the object 2 to be positioned at one of the first and second positions, which are stable positions, and cannot be stably positioned at the positions therebetween.

The two-position quick switching device according to the present invention having the structure as described above is capable of quickly positioning the object from the first position to the second position or vice versa, and at an intermediate position other than the first position and the second position. Since the object can not be located, there is no operation error caused by the operator's mistake, and even if repeated operation does not cause an error there is an effect capable of accurate operation.
