Abstract

This application discloses a pinball machine pull rod, including a handle, a push rod, a sleeve, and a spring. The handle is located at the bottom end of the push rod, and the top end of the push rod passes through the sleeve and reciprocates within the sleeve. The handle includes a cylindrical part, a frustum-shaped part, and an end face, arranged sequentially from right to left. The cross-sectional diameter of the cylindrical part is smaller than that of the frustum-shaped part. The outer surface of the end face is arc-shaped and convex. The spring is located within the sleeve, and the push rod has a limiting ring. When an external force pulls the push rod, the push rod moves backward within the sleeve. One end of the spring is connected to... When the push rod and the limiting ring collide, the spring is in a "compressed state." When the external force is removed, the push rod moves forward inside the sleeve under the restoring force of the spring, and one end of the spring moves away from the push rod limiting ring. The front end of the sleeve is fixedly connected to the external ball plate. The palm-fitting end and the truncated cone part make the grip fit the palm well, avoiding uneven force on the palm and causing hand fatigue. The front end of the sleeve is fixedly connected to the external ball plate to prevent the push rod from accidentally colliding with the external ball plate during reciprocating motion, thus improving the accuracy of the marble launching force.

Description

Technical Field

[0001] This application relates to the field of pinball machine technology, and more specifically, to a pinball machine lever. Background Technology

[0002] Pinball machines are mechatronic entertainment devices that integrate mechanical structures, electronic controls, and interactive gameplay. They are widely used in amusement parks, arcades, and home entertainment settings. The lever is the key component that triggers the launch of the pinball; it must stably push the pinball into the track while avoiding interference with other components.

[0003] In existing technologies, the mounting brackets for the levers mostly rely on "multi-component transition fixation," which makes the impact head prone to accidental collision with the surface of the ball tray (the game table of a pinball machine) during reciprocating motion. Long-term collisions will cause: (1) wear / deformation of the impact head, reducing the accuracy of the pinball launching force; (2) scratches on the surface of the ball tray (such as damage to the track and decorative layer), increasing maintenance costs and equipment lifespan. In addition, the handles of the levers in existing technologies are mostly "cylindrical / conventional shapes," which are not optimized based on ergonomics, resulting in poor fit with the palm when gripping, uneven force distribution, and hand fatigue; that is, in existing technologies, the collision between the lever impact head and the ball tray causes wear, thereby reducing the accuracy of the pinball launching force, and the poor fit between the lever handle and the palm leads to hand fatigue. Utility Model Content

[0004] This application provides a pinball machine lever that can solve the problems in the prior art where the lever impact head collides with the ball disk, causing wear and reducing the accuracy of the pinball launching force, and where the poor fit between the lever handle and the palm leads to hand fatigue.

[0005] To address the aforementioned technical problems, this application provides a pinball machine lever, employing the following technical solution:

[0006] A pinball machine lever includes a handle, a push rod, a sleeve, and a spring. The handle is located at the bottom end of the push rod, and the top end of the push rod passes through the sleeve and reciprocates within the sleeve.

[0007] The handle includes a cylindrical part, a frustum part, and an end face, which are arranged sequentially from right to left. The cross-sectional diameter of the cylindrical part is smaller than that of the frustum part; the outer surface of the end face is arc-shaped and convex.

[0008] The spring is located inside the sleeve, and the push rod is equipped with a limit ring. When an external force pulls the push rod, the push rod moves backward inside the sleeve, and one end of the spring abuts against the limit ring of the push rod. At this time, the spring is in a "compressed state". When the external force is removed, the push rod moves forward inside the sleeve under the action of the spring's restoring force, and one end of the spring moves away from the limit ring of the push rod.

[0009] The front end of the sleeve is fixedly connected to the external ball plate.

[0010] In some embodiments, the cross-sections of the cylindrical portion, the frustum portion, and the end portion are all circular.

[0011] In some embodiments, the cross-sectional diameter of the cylindrical portion is consistent from right to left, the cross-sectional diameter of the frustum portion increases sequentially from right to left, and the cross-sectional diameter of the end portion decreases sequentially from right to left.

[0012] In some embodiments, the top of the push rod is provided with an impact head.

[0013] In some embodiments, the impact head includes a sleeve and an impact part, wherein the cross-sectional diameter of the sleeve is larger than the cross-sectional diameter of the impact part.

[0014] In some embodiments, a limiting plate is also included, which is disposed on the sleeve.

[0015] In some embodiments, the sleeve is provided with an annular protrusion, and the limiting plate is fixedly connected to the annular protrusion.

[0016] In some embodiments, the limiting plate is provided with a through hole, and the diameter of the limiting ring cross-section is larger than the diameter of the through hole.

[0017] Compared with the prior art, the embodiments of this application have the following main advantages:

[0018] This pinball machine lever includes a handle, a push rod, a sleeve, and a spring. The handle is located at the bottom of the push rod, and the top of the push rod passes through the sleeve and reciprocates within the sleeve. The handle includes a cylindrical part, a frustum-shaped part, and an end face, arranged sequentially from right to left. The cross-sectional diameter of the cylindrical part is smaller than that of the frustum-shaped part. The outer surface of the end face is arc-shaped and convex. The spring is located inside the sleeve. The push rod has a limiting ring. When an external force pulls the push rod, it moves backward within the sleeve, and one end of the spring contacts the limiting ring of the push rod. At this time, the spring is in a "compressed state." When the external force is removed, the push rod moves forward within the sleeve under the restoring force of the spring, and one end of the spring moves away from the limiting ring of the push rod. The front end of the sleeve is fixedly connected to an external ball plate. When using this pinball machine lever, the operator holds the handle with their palm against the end face and the frustum-shaped part. The design ensures a high degree of fit between the handle and the palm, conforming to ergonomic principles and preventing hand fatigue caused by uneven pressure. When the handle is gripped, the push rod is pulled by an external force, moving backward within the sleeve. One end of the spring contacts the push rod limit ring, at which point the spring is in a "compressed state." Releasing the hand removes the external force, and the push rod moves forward within the sleeve under the spring's restoring force, with one end of the spring moving away from the push rod limit ring. Because the front end of the sleeve is fixedly connected to the external ball plate, accidental collisions between the push rod and the external ball plate (the pinball machine's table surface) during reciprocating motion are prevented, improving the accuracy of pinball launch force. This solves the problems of wear caused by collisions between the pull rod impact head and the ball plate in existing technologies, which reduces the accuracy of pinball launch force, and hand fatigue caused by poor fit between the pull rod handle and the palm.

[0027] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Unless otherwise specified, the materials and equipment used in this embodiment are all commercially available.

In the description of this application, "a plurality of" means two or more, unless otherwise precisely specified.

[0029] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "connected," "linked," and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a connection through an intermediary, or a connection within two elements or an interaction between two elements. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0030] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or apparatus.

[0031] This application provides a pinball machine lever, such as... Figures 1 to 5 As shown, it includes a handle 1, a push rod 2, a sleeve 3, a spring 4 and a limiting plate 5. The handle 1 is located at the bottom end of the push rod 2, and the top end of the push rod 2 passes through the sleeve 3 and reciprocates within the sleeve 3.

[0032] The grip 1 includes a cylindrical portion 11, a frustum portion 12, and an end portion 13, arranged sequentially from right to left. The cross-sections of the cylindrical portion 11, frustum portion 12, and end portion 13 are all circular. The diameter of the cylindrical portion 11 is smaller than that of the frustum portion 12. The diameter of the cylindrical portion 11 is consistent from right to left, while the diameter of the frustum portion 12 increases sequentially from right to left, and the diameter of the end portion 13 decreases sequentially from right to left. The outer surface of the end portion 13 is arc-shaped and convex. When using the pinball machine lever, the operator grips the grip 1, ensuring that the palm fits the end portion 13 and the frustum portion 12. This ensures a high degree of fit between the grip 1 and the palm, conforming to ergonomics and preventing uneven pressure on the palm, which can lead to hand fatigue.

[0033] The sleeve 3 has an annular protrusion 31, and the limiting plate 5 is fixedly connected to the annular protrusion 31 (screws are used to sequentially pass through the annular protrusion 31 and the limiting plate 5, so that the annular protrusion 31 and the limiting plate 5 are fixedly installed together), that is, the limiting plate 5 is fixedly installed on the sleeve 3. Then, screws are used to sequentially pass through the annular protrusion 31, the limiting plate 5 and the outer ball plate, so that the annular protrusion 31, the limiting plate 5 and the outer ball plate are fixedly installed together (that is, the front end of the sleeve 3 is fixedly connected to the outer ball plate).

[0034] Spring 4 is placed inside sleeve 3. A limiting ring 21 is provided on top rod 2, and a through hole 51 is provided on limiting plate 5. The cross-sectional diameter of limiting ring 21 is larger than the diameter of through hole 51.

[0035] The top of the push rod 2 is provided with an impact head 22, which includes a sleeve 221 and an impact part 222. The cross-sectional diameter of the sleeve 221 is larger than the cross-sectional diameter of the impact part 222.

[0036] When an external force pulls the push rod 2, the push rod 2 moves backward inside the sleeve 3. One end of the spring 4 abuts against the limiting ring 21 of the push rod 2. At this time, the spring 4 is in a "compressed state". When the external force is removed, the push rod 2 moves forward inside the sleeve 3 under the action of the restoring force of the spring 4. One end of the spring 4 moves away from the limiting ring 21 of the push rod 2.

[0037] When the handle 1 is gripped, the push rod 2 is pulled by an external force, causing it to move backward within the sleeve 3. One end of the spring 4 contacts the limiting ring 21 of the push rod 2, at which point the spring 4 is in a compressed state. Then, the hand is released, removing the external force. Under the restoring force of the spring 4, the push rod 2 moves forward within the sleeve 3, and one end of the spring 4 moves away from the limiting ring 21 of the push rod 2 (at this point, the impact head 22 at the tip of the push rod 2 accurately hits the marble on the external ball plate). Because the front end of the sleeve 3 is fixedly connected to the external ball plate, accidental collisions between the push rod 2 and the surface of the external ball plate (the pinball machine's table surface) during reciprocating motion are avoided, improving the accuracy of the marble's launching force.

[0038] This pinball machine pull rod includes a handle 1, a push rod 2, a sleeve 3, and a spring 4. The handle 1 is located at the bottom end of the push rod 2, and the top end of the push rod 2 passes through the sleeve 3 and reciprocates within the sleeve 3. The handle 1 includes a cylindrical portion 11, a frustum-shaped portion 12, and an end portion 13, arranged sequentially from right to left. The cross-sectional diameter of the cylindrical portion 11 is smaller than the cross-sectional diameter of the frustum-shaped portion 12. The outer surface of the end portion 13 is arc-shaped and convex. The spring 4 is located inside the sleeve 3, and the push rod... 2. A limiting ring 21 is provided. When an external force pulls the push rod 2, the push rod 2 moves backward within the sleeve 3. One end of the spring 4 abuts against the limiting ring 21 of the push rod 2. At this time, the spring 4 is in a "compressed state". When the external force is removed, the push rod 2 moves forward within the sleeve 3 under the action of the restoring force of the spring 4, and one end of the spring 4 moves away from the limiting ring 21 of the push rod 2. The front end of the sleeve 3 is fixedly connected to the external ball plate. When using the push rod of this pinball machine, the operator holds the handle 1 with their hand, so that the palm of their hand... The fitting end face 13 and the frustum portion 12 ensure a high degree of fit between the handle 1 and the palm when gripping it, conforming to ergonomics and preventing uneven pressure on the palm that could lead to hand fatigue. When the handle 1 is gripped, the push rod 2 is pulled by an external force, moving backward within the sleeve 3. One end of the spring 4 abuts against the limiting ring 21 of the push rod 2, at which point the spring 4 is in a "compressed state." Then, when the palm is released and the external force is removed, the push rod 2 returns to its original position under the restoring force of the spring 4. When in use, the push rod 2 moves forward inside the sleeve 3, and one end of the spring 4 moves away from the limiting ring 21 of the push rod 2. Since the front end of the sleeve 3 is fixedly connected to the external ball plate, it can prevent the push rod 2 from accidentally colliding with the surface of the external ball plate (the game table of the pinball machine) during reciprocating motion, thereby improving the accuracy of the pinball launching force. This can solve the problem in the prior art where the pull rod impact head 22 collides with the ball plate, causing wear and reducing the accuracy of the pinball launching force. In addition, the poor fit between the handle of the pull rod and the palm of the hand leads to hand fatigue.
