[0005] The purpose of this invention is to provide a pressing structure.

[0006] To achieve the above objectives, the present invention provides the following technical solution.

[0007] A pressing structure includes a movable component, a fixed component, and a trackball; characterized in that the movable component and the fixed component are capable of relative movement, the movable component is provided with a first groove, and the fixed component is provided with a second groove.

[0008] The trackball is disposed between the first groove and the second groove. The movement trajectory includes an initial point, a turning point, and a locking point. When the fixed member and the movable member move relative to each other, the first groove and the second groove form a movement trajectory. After the trackball moves along the movement trajectory to the turning point, it reaches the locking point along the movement trajectory, thereby locking the pressing structure. When the fixed member and the movable member move relative to each other again, the trackball reaches the initial point along the movement trajectory, thereby unlocking the pressing structure.

[0009] Preferably, the end of the movable part is provided with a pressing head, which is exposed at the top of the fixed part and is used to receive external pressing force.

[0010] Preferably, the trackball is a spherical object made of wear-resistant and corrosion-resistant material.

[0011] Preferably, the fixing member has a through hole, and the second groove is an annular groove. The second groove is disposed on the inner wall of the through hole. Under the action of external force, when the movable member drives the track ball to move relative to each other in the through hole of the fixing member, the first groove and the second groove form a motion trajectory.

[0012] Preferably, the fastener is divided into an upper fastener and a lower fastener, and the upper fastener and the lower fastener are fixedly connected by means of threads, interference fit, adhesive, or adapter.

[0013] Preferably, the first groove of the movable component is a trackball positioning groove, the lower end of the upper fixing component has an irregular tooth shape, and the upper end of the lower fixing component also has an irregular tooth shape. The upper fixing component and the lower fixing component are connected by an adapter. At the same time, the area formed between the upper fixing component and the lower fixing component is the second groove. Under the action of external force, when the movable component drives the trackball to move relative to each other in the second groove, the first groove and the second groove form a motion trajectory.

[0014] Preferably, the motion trajectory is defined by the first groove and the second groove as a waveform trajectory, a polygonal trajectory, or a curved trajectory.

[0015] Preferably, the bottom end of the movable part is provided with a mating part, the end of the mating part away from the movable part is provided with a spring retainer, and the bottom end of the cavity of the lower fixed part is provided with a spring stop position. When the movable part is pressed, the spring is used to provide axial rebound force.

[0016] Preferably, the initial point, turning point, and locking point are distributed sequentially and continuously on the cylindrical surface in the order of initial point, turning point, and locking point.

[0017] In the above technical solution, the pressing structure provided by this utility model has the following beneficial effects.

[0018] The pressing structure provided by this utility model breaks away from the toothed pressing structure of traditional plastic pressing pens by using the motion trajectory formed by the relative movement of the trackball between the moving and fixed parts. At the same time, it meets the functional requirements of positioning and locking and positioning and unlocking with fewer parts. Applying this pressing structure to switches, pressing pens and precision positioning products not only saves costs, but also reduces the difficulty of processing. Attached Figure Description

Therefore, they should not be construed as limitations on this application.

[0028] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] like Figure 1 and Figure 2 As shown, a pressing structure mainly includes a movable part (1), a fixed part (2), and a trackball (3). The movable part (1) is provided with a pressing end (11) and a first groove (10). The fixed part (2) is provided with a through hole (21) and a second groove (20). The trackball is disposed between the first groove and the second groove. The movable part and the fixed part can move relative to each other. When the fixed part (2) moves relative to the movable part (1), the first groove (10) and the second groove (20) form a motion trajectory O.

[0030] like Figure 1 and Figure 2 As shown, the motion trajectory O includes an initial point, a turning point, and a locking point. After the track ball (3) moves along the motion trajectory O to the turning point, it continues along the motion trajectory O to reach the locking point, thereby locking the pressing structure. When the fixed member (2) and the movable member (1) move relative to each other again, the track ball (3) moves along the motion trajectory O to the turning point, and then moves along the motion trajectory O to the locking point, thereby unlocking the pressing structure.

[0031] like Figure 1 and Figure 2 As shown, since it relates to the actual assembly sequence, the fastener (2) is divided into an upper fastener (22) and a lower fastener (23). The lower end of the upper fastener (22) is provided with a first step (221) and a second step (222), and the lower fastener (23) is provided with an end face (231) and a third step (232).

[0032] like Figure 1 and Figure 2 As shown, the first step (221) is higher than the second step (222), and the diameter of the first step (221) is smaller than the diameter of the second step (222), and the diameter of the end face (231) is not greater than the diameter of the second step (222).

[0033] like Figure 1 and Figure 2 As shown, the movable part (1) is slidably installed in the through hole (21) of the fixed part (2); the specific installation sequence is as follows: the end of the movable part (1) away from the pressing end (11) is facing down, and the axis of the movable part (1) is aligned with the axis of the upper fixed part (22) and slid down. Then the track ball (3) is placed at the first step (221). At this time, the end of the lower fixed part (23) with the third step (231) is facing up, and the axis is aligned with the axis of the movable part (1) and slid up until the second step (222) abuts against the end face (231). At this time, the area formed by the assembly of the first step (221), the second step (222) and the end face (231) is the second groove (20) of the fixed part (2). The second groove (20) is an annular groove. The upper fixed part (22) and the lower fixed part (23) can be fixedly connected by a pressing or threaded structure.

[0034] like Figure 1 and Figure 2 As shown, the assembled movable part (1), upper fixed part (22), lower fixed part (23) and trackball (3) are set as pressing components.

[0035] like Figure 3 As shown, the pressing component is applied to the pressing pen, the lower fixing member (23) is extended, the conventional accessory pen refill is installed at the lower end of the pressing component, and the two ends of the spring abut against the inside of the lower fixing member (23) and the outer wall of the pen refill respectively. The pen refill is extended and retracted by pressing the pressing end (11) of the pressing component by external force.

[0036] like Figure 3 and Figure 4 As shown, the second groove (20) is provided with points A, B, C, D, E, F, G and H in sequence; among them, points A and E are initial points, points B, D, F and H are turning points, points C and G are locking points, and there are longitudinal and oblique guide grooves between each pair of adjacent points. These 8 points are continuously distributed on the cylindrical surface where the second groove (20) is located.

[0037] like Figure 3 and Figure 4As shown, the trackball (3) is located at point A, the spring is in its natural state, and the pen tip is not extended, which is the initial state. Pressing the pressing end (11) of the movable part (1) can drive the pen tip to move forward. The trackball (3) moves from point A to point B, the spring is compressed, and the pen tip extends to its maximum length. After completing one pressing action, the trackball (3) slides from point B to point C and locks due to the counter-force of the spring. The spring is still compressed, and the pen tip is in the extended state. When a vertical force is applied to the pressing end (11) of the movable part (1) again, the trackball (3) moves from point C to point B. At point D, the pen tip extends to its maximum length, completing the second pressing action. Simultaneously, due to the counterforce of the spring, the trackball (3) moves from point D to point E, the spring resets, and the pen tip is retracted. Pressing the movable part (1) twice more causes the trackball (3) to move from point E to points F, G, H, and A respectively, completing one extension and retraction movement of the pen tip. Pressing the movable part (1) four times causes the trackball (3) to move four times along points A, B, C, D, E, F, G, and H within the first groove (12), while the pen tip completes two extension and retraction movements. This achieves the positioning locking and unlocking of the pen tip by the pressing structure on the pressing pen.

[0038] like Figure 3 As shown, the fixing member (2) is made of transparent material and the track ball (3) is made of bright color and wear-resistant and corrosion-resistant material. When the pressing end (11) of the pressing component is applied and pressed repeatedly, the user can observe with the naked eye that the track ball (3) moves in the motion trajectory O formed by the first groove (10) and the second groove (20).

[0039] like Figure 5 , Figure 6 and Figure 7 As shown, a pressing structure mainly includes a movable part (1), an upper fixed part (22), a lower fixed part (23), a trackball (3), a connector (4), and a screw (5). The movable part (1) is provided with a pressing end (11) and a first groove (10).

[0040] like Figure 5 , Figure 6 and Figure 7As shown, the upper fixing member (22) and the lower fixing member (23) are provided with through holes (21), the diameter of the through holes (21) is larger than the diameter of the movable member (1), the lower end of the upper fixing member (22) is provided with an irregular upper tooth shape S1, the upper tooth shape S1 is provided with initial points: points A and E, and locking points C and G; the upper end of the lower fixing member (23) is also provided with an irregular lower tooth shape S2, the lower tooth shape S2 is provided with turning points B, D, F and H, the cylinders where the upper tooth shape S1 and the lower tooth shape S2 are located have the same diameter, and the diameter of the through hole of the adapter (4) is larger than the diameter of the cylinders where the upper tooth shape S1 and the lower tooth shape S2 are located, the upper tooth shape S1 and the lower tooth shape S2 are provided with longitudinal and oblique guide surfaces.

[0041] like Figure 5 , Figure 6 and Figure 7 As shown, the installation sequence is as follows: With the pressing end (11) of the movable part (1) facing upwards, align the axis with the through hole of the upper fixing part (22) and insert it. Align the first groove (10) with the initial point A of the upper fixing part (22). Then, align the adapter (4) with the upper fixing part (23) from below, so that the upper tooth-shaped form S1 of the upper fixing part (22) is inserted into the through hole of the adapter (4) and blocked. Then, insert the lower tooth-shaped form S2 of the lower fixing part (23) upwards into the adapter (4) and be blocked. When the turning point B is located to the right of the initial point A, the area formed between the upper fixing part (22) and the lower fixing part (23) is the second groove (20). Points A, B, C, D, E, F, G, and H are arranged in a counterclockwise order on the cylindrical surface formed by the installation of the upper fixing part (22) and the lower fixing part (23). Finally, the upper fixing part (22) and the lower fixing part (23) are fixedly connected to the adapter (4) by screws (5).

[0042] like Figure 5 , Figure 6 and Figure 7 As shown, when the assembly of the trackball (3), the upper fixing member (22), the lower fixing member (23), the adapter (4) and the screw (5) moves relative to the movable member (1), the second groove (20) is the trajectory O of the trackball (3).

[0043] like Figure 5 , Figure 6 and Figure 7As shown, when a certain external force is applied to the pressing end (11) of the movable part (1), the track ball (3) moves from the initial point A along the second groove (20) to the turning point B, and continues along the second groove (20) to the locking point C, thereby locking the pressing structure; when a vertical force is applied to the pressing end (11) of the movable part (1) again, the track ball (3) moves from the locking point C along the second groove (20) to the turning point D, and continues along the second groove (20) to the locking point E, thereby unlocking the pressing structure. Similarly, when the pressing end (11) is pressed twice, the track ball (3) completes one locking and one unlocking from points E, F, G, and H.
