Description

Technical Field

[0001] This utility model relates to the field of triangular frame technology, and in particular to a triangular frame that facilitates the standardized placement of balls. Background Technology

[0002] In billiards, ball placement is a necessary step before the game begins, and the triangular frame is one of the core tools for achieving standardized ball placement. Currently, commercially available triangular frames typically consist of several rigid frames joined together to form an isosceles triangle structure. These frames are mostly straight lines, and the materials are primarily wood (bamboo) or plastic. In actual ball placement, a specified number of balls must be placed into the triangular frame and pushed tightly to form a closely packed ball pile. However, in the use of traditional triangular frames, because the radii of the three inner corners are larger than the radii of the balls, and the placement relies on the inertia generated by manually pushing the frame or manually pushing the balls, the ball placement becomes irregular, resulting in uneven spacing between the balls. Therefore, this invention proposes a triangular frame that facilitates standardized ball placement. Utility Model Content

[0003] The purpose of this invention is to address the problem in the background technology that the traditional triangular frame has three inner corner radii larger than the ball radius, and the ball is not swung properly and the gaps between the balls are uneven due to the inertia of the triangular frame being pushed by manpower or the ball being pushed tightly by hand. The invention proposes a triangular frame that facilitates standardized ball swaying.

[0004] The technical solution of this utility model is as follows: a triangular frame for facilitating standardized ball placement, comprising a triangular frame body; a push plate disposed on one side of the triangular frame body; two sets of compensation mechanisms, the two sets of compensation mechanisms being respectively installed on the other two sides of the triangular frame body, each compensation mechanism including a groove formed on the outer side of the triangular frame body, a button slidably connected in the groove, a connecting rod installed on the side of the button near the triangular frame body, the connecting rod penetrating the triangular frame body and being fixedly connected to a pressing plate.

[0005] Optionally, the radii of the three interior corners of the triangular frame are all smaller than the radius of the billiard ball.

[0006] Optionally, the button has a connecting groove on the side near the triangular frame, one end of the connecting rod is fixedly connected to the connecting groove, a spring is sleeved on the outer ring of the connecting rod, the spring is set in the groove, and one end of the spring is located in the connecting groove.

[0007] Optionally, the two inner sides of the triangular frame corresponding to the compensation mechanism are each covered with a piece of felt, and the connecting rod and the extrusion plate pass through the felt.

[0008] Optionally, a mounting groove corresponding to the push plate is provided on one side of the triangular frame, the push plate is installed in the mounting groove, and two sets of limiting grooves are provided inside the mounting groove, the two sets of limiting grooves are symmetrically arranged at both ends of the push plate.

[0009] Optionally, limit blocks corresponding to the limit grooves are installed at both ends of the push plate.

[0010] Optionally, the push plate is rotatably connected to two ends of a rotating shaft, the rotating shaft is installed inside the mounting groove, and a return spring is installed on the rotating shaft.

[0011] Optionally, a positioning mark is provided on the top of the push plate, and the positioning mark is located at the center of the push plate.

[0012] Optionally, through holes are provided at the triangular positions of the triangular frame.

[0013] In summary, this application includes at least one of the following beneficial technical effects:

[0014] This invention uses a triangular frame with an inner corner radius smaller than the ball radius, so that the foremost ball is limited to the frame through only two points of contact, significantly reducing the contact area. This design not only forces the balls to squeeze together to form a close arrangement through geometric constraints, eliminating the gap problem of traditional straight frame, but also avoids ball wear caused by large-area friction, extending the life of the billiard balls. At the same time, when the triangular frame is removed, the minimal contact friction force is unlikely to disturb the already arranged ball pile, ensuring the stability of the ball placement position.

[0015] Furthermore, through the linkage design of the push plate and the return spring via the rotating shaft, after the ball is swung, the return spring and the spring force automatically drive the push plate and the squeeze plate to return to their original positions, avoiding the tedious process of repeated adjustments required by traditional manual ball swivel and improving ball swivel efficiency;

[0016] In summary, this invention can eliminate gaps between balls, improve the tightness and standardization of ball placement, ensure the fairness and entertainment value of the competition, and improve ball placement efficiency and accuracy. Attached Figure Description

[0027] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0028] The components of the present invention embodiments described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0029] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0032] like Figure 1 As shown, this utility model proposes a triangular frame for facilitating standardized ball placement. The frame includes a triangular frame body 1, where the radii of its three interior angles are all smaller than the radius of the billiard balls. This ensures that when the billiard balls are pushed tightly, the foremost ball only has two points of contact with the triangular frame body 1, resulting in a small contact area and preventing excessive wear caused by excessive contact. The smaller contact area also facilitates removing the triangular frame body 1 after pushing the balls tightly without easily affecting their position. Through holes 13 are provided at each of the triangular positions of the triangular frame body 1. These through holes reduce weight and facilitate hanging the triangular frame body 1.

[0033] For further details, please refer to Figure 1 , Figure 4 and Figure 5 The aforementioned triangular frame includes a push plate 2 disposed on one side of the triangular frame body 1. A mounting groove 11 corresponding to the push plate 2 is provided on one side of the triangular frame body 1, and the push plate 2 is installed in the mounting groove 11. Two sets of limiting grooves 12 are provided inside the mounting groove 11, symmetrically arranged at both ends of the push plate 2. Limiting blocks 21 corresponding to the limiting grooves 12 are respectively installed at both ends of the push plate 2. The limiting grooves 12 and limiting blocks 21 prevent the push plate 2 from moving outwards from the triangular frame body 1. Rotating shafts 22 are rotatably connected to both ends of the push plate 2. The rotating shafts 22 are installed inside the mounting groove 11. The rotating shafts 22 allow the push plate 2 to be rotatably connected to the mounting groove 11, facilitating the rotation of the rotating shafts 22 and pushing multiple sets of billiard balls inwards from the triangular frame body 1, thus ensuring the billiard balls are firmly pushed inwards. A return spring 23 is installed on the rotating shaft 22. The return spring 23 is used to accumulate elastic force when the rotating shaft 22 rotates inward towards the triangular frame 1, so that the push plate 2 can be reset by the elastic force of the return spring 23 when the external force is removed. The top of the push plate 2 is provided with a positioning mark 24, which is set at the center of the push plate 2, so as to facilitate the positioning of the billiard ball in the center position in conjunction with the compensation mechanism 4.

[0034] Furthermore, such as Figure 2 and Figure 3As shown, the aforementioned triangular frame also includes two sets of compensation mechanisms 4, which are respectively installed on the other two sides of the triangular frame 1. The compensation mechanisms 4 are used to compensate for the tolerance of the billiard balls and ensure that the ball placement position is standardized. The compensation mechanism 4 includes a groove 41 opened on the outside of the triangular frame 1. A button 42 is slidably connected in the groove 41, and the button 42 moves smoothly in the groove 41. A connecting rod 44 is installed on the side of the button 42 near the triangular frame 1. The connecting rod 44 passes through the triangular frame 1 and is fixedly connected to a pressing plate 45. When the button 42 moves, it drives the pressing plate 45 to move through the connecting rod 44. A connecting groove 43 is provided on the side of button 42 near the triangular frame 1. One end of connecting rod 44 is fixedly connected to the connecting groove 43. A spring 46 is installed on the outer ring of connecting rod 44. The spring 46 is set in the groove 41. One end of spring 46 is located in the connecting groove 43. When button 42 is pressed, the pressing plate 45 is pressed to squeeze the billiard ball. When button 42 is released, spring 46 releases its elastic force to drive the pressing plate 45 to return to its original position.

[0035] The two inner sides of the triangular frame 1 and the compensation mechanism 4 are both equipped with velvet 3. The connecting rod 44 and the extrusion plate 45 pass through the velvet 3. The velvet 3 reduces the friction between the billiard ball and the triangular frame 1 and prevents wear.

[0036] In this embodiment, after placing the billiard balls into the triangular frame 1 and adjusting their order, the operator holds the triangular frame 1 at its two corners and pushes the push plate 2 with their thumbs. The push plate 2 rotates around the pivot 22, with one end of the pivot 22 contacting multiple billiard balls and pressing them firmly. Simultaneously, the push plate 2's rotation causes the return spring 23 to deform. The operator then presses the button 42 in the two sets of compensation mechanisms 4. The button 42, through the connecting rod 44, causes the compression plate 45 to contact the billiard balls, simultaneously compressing the spring 46. At this point, the positions of the multiple billiard balls are adjusted by the compression plate 45. Releasing the push plate 2 releases the spring force of the return spring 23, causing the push plate 2 to return to its original position. Releasing the button 42 again releases the spring force of the spring 46, causing the button 42 to return to its original position, and the compression plate 45 moves away from the billiard balls. Finally, pushing the triangular frame 1 separates the billiard balls from the frame, making it easier to lift the frame 1 upwards, completing the billiard ball placement.

[0037] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
