[0020] As shown in the figure, a billiard cue straightening device includes a slide rail 100, a straightening mechanism 200 and a roller;

[0021] The slide rail 100 is a U-shaped strip structure, which is used to align the support base of the billiard cue 500, and is stacked together with the billiard cue 500 in the oven for subsequent curing of the billiard cue 500. In this embodiment, the slide rail 100 is made of channel steel, and its two wing plates are used as slideways. The integrated structure has good integrity and high strength, is not easy to bend in the oven, and has small deflection.

[0022] The rollers include a first roller 300 and a second roller 400, which are distributed at both ends of the slide rail 100 to support the billiard cue 500. The first roller 300 and the second roller 400 translate on the slide rail 100 and adjust the spacing so that the axis of the billiard cue 500 is parallel to the slide rail 100, which is convenient for straightening the billiard cue 500. In this embodiment, the slide rail 100 is used as a reference to facilitate straightening the billiard cue 500.

[0023] The straightening mechanism 200 is assembled in the middle of the slide rail 100 , and its lower part is sleeved on the slide rail 100 and locked and fixed, and its upper part is provided with a pressing mechanism 220 to press the billiard cue 500 through a pressing block 230 to adjust the straightness of the billiard cue.

[0024] In order to ensure the stability of the structure of the utility model, the straightening mechanism 200 includes a frame 210, a pressing mechanism 220, a pressing block 230 and a seat plate 240; the frame 210 is a closed structural frame, and a seat plate 240 is provided at the lower part of the frame 210 to separate it into a containing cavity, which is mounted on the slide rail 100. The frame 210 can move parallel to the slide rail 100, so that the straightening mechanism 200 is fixed at the required position of the slide rail 100 to press the billiard cue 500 according to the length of the billiard cue 500; the pressing mechanism 220 is provided on the frame 210, and the pressing mechanism 220 pulls the pressing block 230 to compact the billiard cue 500 supported on the first roller 300 and the second roller 400 to perform the straightening operation.

[0025] In order to further ensure the stability of the structure of the utility model, the pressing mechanism 220 includes a screw 221, a nut 222 and a rotating rod 223; a nut 222 is provided at the top of the frame 210, the screw 221 penetrates the nut 222 from top to bottom, and a rotating rod 223 is connected to the top of the screw 221 for rotating the screw 221 to lift and lower; the bottom of the screw 221 is connected and fixed to the pressure block 230.

[0026] In order to optimize the structure of the utility model, the pressing block 230 is a long strip with a flat upper portion and an arc lower portion, the upper portion of which is connected to the bottom of the lead screw 221, and the top of the arc of the lower portion is perpendicularly intersected and linearly contacted with the contour line of the billiard cue 500, and the pressing block 230 is pressed on the billiard cue 500. In this embodiment, the bottom arc of the pressing block 230 is in linear contact with the outer contour of the billiard cue 500, with only one force point, and after the pressing block 230 presses down the billiard cue 500, it can be accurately aligned with the warping point, so as to realize the straightness correction of the billiard cue 500.

[0027] In order to further optimize the structure of the utility model, the first roller 300 is a short shaft with a plane at the lower part. Roller seats 310 are arranged at both ends of the first roller 300. The outer ends of the roller seats 310 are provided with limiting grooves 320. The first roller 300 is assembled on the slide rail 100 through the limiting grooves 320, and can move linearly along the slide rail 100 to adjust its position thereon; a groove 330 is arranged between the two roller seats 310, and a semicircular arc portion 331 is arranged on the top of the groove 330. The contour of the semicircular arc portion 331 corresponds to the contour of the billiard cue 500, so that the billiard cue 500 is mounted on the semicircular arc portion 331 to form a stable support point, thereby reducing the wear of the billiard cue 500 during straightening.

[0028] In order to further optimize the structure of the present invention, the second roller 400 has the same structure as the first roller 300, and also has a roller seat 310, a limiting groove 320 and a groove 330, but the semicircular arc portion 331 on the groove 330 has different geometric dimensions from the semicircular arc portion 331 on the first roller 300, which matches the taper of the billiard cue 500; by adjusting the distance between the first roller 300 and the second roller 400, the axis line of the billiard cue 500 located thereon can be made parallel to the slide rail 100, the axis line of the billiard cue 500 is determined, and a straightening mechanism 200 is set at the warping point of the billiard cue 500 to apply a force to achieve straightness straightening.

[0029] As a conventional technical choice, during the working process of this embodiment, first, a standard billiard cue is used to adjust the distance between the first roller 300 and the second roller 400. When the axis of the standard billiard cue is parallel to the slide rail 100, the positions of the first roller 300 and the second roller 400 are determined; secondly, a ruler or a dial indicator is moved on the slide rail 100 to accurately adjust the bending size of each part of the billiard cue 500 to determine the downward pressing position of the straightening mechanism 200; finally, the straightness of the billiard cue 500 is adjusted and transferred to a drying box for subsequent curing.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
