Summary of the invention

The object of the present invention is to provide a pressing and telescopic mechanism for use in stationery, and a stationery with the same, which can make the connecting rod extend when in use and can be retracted when idle, suitable for people to separate. With one hand operation, the press telescopic mechanism has the characteristics of simple structure and low requirements for component manufacturing precision.

The pressing and contracting mechanism of the present invention applied to stationery is realized by the following scheme: N2014/000520 A pressing and telescopic mechanism for use in stationery, comprising: an action member, a fixing member and a spring; the action member is formed with a τ-shaped rod, the τ-shaped rod has an upright portion and a horizontal portion, and the action member is in a T shape At least one connecting rod is arranged beside the rod; the fixing member is formed with two opposite and downwardly folded rails, and the rails are arranged in the middle of the two rails, the rails are the rails leaving the right lane, and the right rail is used as the guiding track, the rail The left side of the track and the right side of the track are respectively a left track and a right track; the ends of the two tracks are formed with a platform, a slope is formed between the guide track and the platform, and the end of the slope is slightly higher than the platform, the track and the platform A concave portion is formed between the two; the τ-shaped rod of the action member is located between the two rails, and the two ends of the horizontal portion of the T-shaped rod are respectively located above the two guide rails, and the action member is subjected to the upward force of the spring.

In this way, when the external force moves the action member downward, the τ-shaped rod can be moved downward, and the two ends of the horizontal portion of the T-shaped rod will travel downward along the two right-row rails respectively, and under the guidance of the guide track, After falling into the two platforms through the two slopes, when the external force is released, under the action of the spring force, the action member will move upward, so that the two ends of the horizontal portion of the τ-shaped rod will slide into the two recesses from the two platforms. At this time, the τ shape The rod is no longer moved relative to the fixed member. In this process, the connecting rod is fixed with the moving member moving downward; after use, the action member can be pressed again, at this time, the two ends of the horizontal portion of the τ-shaped rod will be Passing through the two recesses and entering the two platforms respectively, and sliding from the two platforms to the two left rails, when the external force is released, under the action of the spring force, the two ends of the horizontal portion of the τ-shaped rod will move up along the two left rails. , return to the initial position, in the process, the connecting rod moves up with the action piece.

Thus, a press-and-expansion mechanism that can move the connecting rod downward or upward by pressing the actuating member is obtained.

In the scheme, when the two rails are in a collapsed state, when the horizontal portion of the τ-shaped rod is moved downward along the two right rails by an external force, the deformation of the two rails is accompanied by widening the spacing of the rails when the external force is released. Under the action of the spring force, the horizontal part of the τ-shaped rod will move upwards and the orbit will gradually recover. N2014/000520 Reverts to narrow the track pitch. Therefore, during operation, the two tracks have the ability to recover their own deformation and clamp the two ends of the horizontal portion of the τ-shaped bar.

In the scheme, the end of the horizontal portion of the τ-shaped rod will slide to the left rail after entering the platform beyond the concave portion. Therefore, the τ-shaped rod itself will be bent, and then, under the action of the spring force, the left-hand rail will be attached. Moving up, therefore, it also has the ability to restore itself to the top.

The pressing and telescopic mechanism created by the invention has the clamping effect of the two rails on the τ-shaped rod, so that the clamping of the rail can be utilized to ensure the accuracy of the horizontal portion of the τ-shaped rod and the position of the rail, thereby ensuring the two ends of the horizontal portion. The department can enter the two platforms or two recesses accurately and simultaneously.

In the pressing and telescopic mechanism of the present invention, since the end portion of the horizontal portion of the τ-shaped rod passes over the concave portion into the platform and slides to the left traveling rail, the two rails will be deformed to narrow the pitch, so that the two portions of the horizontal portion of the τ-shaped rod It is impossible for the end to return to the platform and has to be in the left track. Therefore, the automatic transformation of the horizontal portion of the τ-shaped rod is realized, and the accuracy of the orbit is ensured.

Since the end portion of the horizontal portion of the τ-shaped rod enters the platform and slides to the left rail after crossing the concave portion, the τ-shaped rod itself is bent, so that the horizontal portion of the τ-shaped rod is attached to the left-hand rail, and The spring force moves upwards. When it is disengaged at the upper end of the left rail, the τ-shaped rod will return to its original shape, no longer bend, return to the original position and be above the guiding track, thus realizing the horizontal part of the τ-shaped rod. The automatic change of the track again, and the accuracy of the track change is guaranteed.

In this solution, the structure of the rails, the guide rails, the slopes, the platform and the recesses are used, and the deformation of the rails and the bending of the τ-shaped rods are utilized to realize the orbital change of the actuating members, so that the accuracy of the stroke of the actuating members can be obtained. As a guarantee, in particular, compared with the prior art, the use of serrations, axial ribs and axial grooves is no longer used, which greatly reduces the requirements for precision in the production and assembly of parts, allowing parts to be produced. Large errors, which reduce the difficulty of manufacturing parts and improve the product Product rate.

In the text, the spring can be installed between the action member and the fixing member, or between the member fixed to the fixing member and the connecting rod, and can also be mounted on the member fixed to the fixing member and connected to the connecting rod. Between the components and the like, the action member can be further compressed to ensure that the spring force can exert a jacking effect on the action member when the external force is withdrawn.

In the above solution, the fixing body is a ring member, and the two rails are distributed on the ring member, so that the assembling operation of the fixing member can be simplified and the manufacturing is convenient.

In the above solution, the portion of the slope end higher than the platform presents a step with a short outer length, and the step can not only prevent the end portion of the horizontal portion of the T-shaped rod from sliding back into the right rail and the guide track, but also further ensure The end of the horizontal portion of the τ-shaped rod can only slide into the left rail in subsequent operations. In the above solution, the transition between the concave portion and the platform is made by the slope, so that the end portion of the horizontal portion of the τ-shaped rod enters the platform from the concave portion via the slope, which makes the operation easier and the process more stable.

In the above scheme, the left side of the rail and the left rail are in the same plane, which can provide a more solid left rail for the horizontal portion of the τ-shaped rod.
