Description

Technical Field

[0001] This utility model belongs to the field of automatic press-type pens, and specifically relates to a pressing mechanism for an automatic press-type pen. Background Technology

[0002] An automatic press pen is a writing instrument with intelligent press function. It mainly uses built-in mechanical structure (such as springs and gears) to realize the automatic extension, retraction or pressure adjustment of the pen tip, without the need for repeated manual pressing.

[0003] In the use of existing automatic press-button pens, the pressing lever is often accidentally triggered by external pressure or touch, affecting the convenience and reliability of use. For example, when the pen is placed in a pocket or bag, the pressing lever is easily pressed down due to pressure, causing ink to flow out or the function to be activated erroneously. In order to solve the above problems, a pressing mechanism for an automatic press-button pen is proposed. Utility Model Content

[0004] In view of one or more of the above-mentioned defects or improvement needs of the prior art, this utility model provides a pressing mechanism for an automatic pressing pen, which has the advantage of preventing accidental touch.

[0005] To achieve the above objectives, this utility model provides a pressing mechanism for an automatic pressing pen, including a pen body and a pressing rod;

[0006] The drive ring is rotatably mounted on the stylus.

[0007] An elastic reset element is mounted on the drive ring;

[0008] The fastener is installed on the elastic reset component.

[0009] A connector is provided on the pressing rod and can be slidably inserted into the fastener to engage with it;

[0010] The fastener is used to limit the insertion of the connector to prevent accidental activation of the pressing rod. The elastic reset element provides elastic tension to the fastener to maintain its current state. The drive ring drives the elastic reset element and the fastener to rotate, thereby releasing the limit on the insertion of the connector and allowing the pressing rod to press down normally.

[0011] Furthermore, the drive ring achieves a rotational connection with the pen body via a bearing.

[0012] Furthermore, the elastic reset component includes a stop block one disposed on the outer wall of the pen body; a rotating ring disposed on the drive ring; and a stop block two disposed on the inner wall of the rotating ring; the stop block one and the stop block two are elastically connected by a spring.

[0013] Furthermore, the fastening element includes a rotating sleeve disposed on the swivel ring; and several fastening strips disposed inside the rotating sleeve.

[0014] Furthermore, the connector includes a pressure plate sleeved on the outer wall of the pressing rod; and several connector strips disposed at the bottom of the pressure plate, the bottom end of which slides through the top of the rotating sleeve and engages with the fastening strip.

[0015] Furthermore, the top of the swivel sleeve has a hole for the insertion strip to pass through.

[0016] Furthermore, both the snap-fit ​​strip and the plug-in strip have an L-shaped structure, and both have beveled edges at the short corners.

[0017] In summary, the beneficial effects of the above-described technical solutions conceived by this utility model compared with the prior art include:

[0018] The pressing mechanism of this utility model's automatic pressing pen effectively prevents accidental pressing by using a snap-fit ​​design to limit the insertion of the plug. At the same time, the use of a drive ring, elastic reset component, and other structures allows the limit to be released when needed, ensuring normal pressing function. Compared with the prior art, this significantly improves the stability and reliability of the pressing pen. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-3 This utility model provides a pressing mechanism for an automatic pressing pen, including a pen body 1 and a pressing rod 2;

[0025] The drive ring 3 is rotatably mounted on the stylus body 1;

[0026] The elastic reset element 4 is disposed on the drive ring 3;

[0027] Fastener 5 is mounted on elastic reset element 4.

[0028] The connector 6 is mounted on the pressing rod 2 and can be slidably inserted into the fastener 5 to fasten it.

[0029] The fastener 5 is used to limit the insertion part 6 to prevent accidental activation of the pressing rod 2. The elastic reset part 4 is used to provide elastic tension to the fastener 5 to maintain its current state. The drive ring 3 is used to drive the elastic reset part 4 and the fastener 5 to rotate, so as to release the limit on the insertion part 6 and allow the pressing rod 2 to press down normally.

[0030] Specifically, refer to Figure 2 The drive ring 3 is connected to the pen body 1 by bearing 7.

[0031] In this embodiment, the drive ring 3 is rotatably mounted on the pen body 1 via the bearing 7, ensuring smooth and flexible rotation, while also providing reliable rotational support for the elastic reset member 4.

[0032] Specifically, refer to Figure 2 The elastic reset component 4 includes a first stop 41 disposed on the outer wall of the pen body 1; a rotating ring 42 disposed on the drive ring 3; and a second stop 43 disposed on the inner wall of the rotating ring 42. The first stop 41 and the second stop 43 are elastically connected by a spring 44.

[0033] In this embodiment, the spring 44 provides elastic tension to the fastener 5 to maintain its initial state and ensure that the fastener 5 limits the insertion of the connector 6 under normal circumstances.

[0034] Specifically, refer to Figure 3 The fastener 5 includes a rotating sleeve 51 disposed on the rotating ring 42; and a plurality of fastening strips 52 disposed inside the rotating sleeve 51.

[0035] Specifically, refer to Figure 3 The connector 6 includes a pressure plate 61 sleeved on the outer wall of the pressing rod 2; and several connector strips 62 disposed at the bottom of the pressure plate 61, the bottom end of the connector strips 62 sliding through the top of the rotating sleeve 51 and engaging with the fastening strip 52.

[0036] In this embodiment, under normal conditions, the spring 44 of the elastic reset member 4 maintains the position of the fastener 5, and the fastening strip 52 limits the downward movement of the insertion strip 62 and the pressing rod 2 to prevent accidental pressing. When the pressing rod 2 needs to be used normally, the drive ring 3 is rotated. The drive ring 3 drives the fastener 5 to rotate through the rotating ring 42, and the fastening strip 52 and the insertion strip 62 are disengaged from the limited state. At this time, the pressing rod 2 can be pressed down. After the drive ring 3 is released, the spring 44 of the elastic reset member 4 resets, driving the drive ring 3 and the fastener 5 to rotate back to the initial position. The fastening strip 52 restores its limit on the pressing rod 2 to avoid subsequent accidental pressing.

[0037] Specifically, refer to Figure 3 The top of the rotating sleeve 51 has a hole for the insertion strip 62 to pass through, providing an insertion path for the insertion strip 62.

[0038] Specifically, refer to Figure 3 Both the snap-fit ​​strip 52 and the insert strip 62 are L-shaped structures, and both have bevels at the short corners. After the insert strip 62 rises with the pressing rod 2 and comes into contact with the snap-fit ​​strip 52, the bevels of both will guide the snap-fit ​​strip 52 and the rotating sleeve 51 to rotate, so that the head of the insert strip 62 can pass through the snap-fit ​​strip 52. After passing through, the snap-fit ​​strip 52 returns to its original position under the action of the spring 44, thus limiting the insert strip 62 again.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
