Description
Technical Field
[0001] The utility model relates to the technical field of center of gravity detection, in particular to a center of gravity detection device for a cue stick. Background Technique
[0002] A billiard cue is a hitting tool made of high-quality wood. There are no strict regulations and requirements for the length and weight of the cue stick. However, the cue stick should not be less than 91 cm at the shortest. But often, due to the too long cue stick, it is not easy to master the hitting force and it is easy to make mistakes. If it is too heavy, it is easy to fatigue the arm and affect the estimation of the hitting force.
[0003] However, after the existing cue sticks are produced, there is no good center of gravity detection device. The center of gravity of a cue stick, that is, the balance point of the front and rear weights of a billiard cue. When the weight is evenly balanced and the center of gravity of the cue stick is in a reasonable position, when lying on the table and making a practice stroke, the weight of the billiard cue can be evenly distributed on the bridge hand and the back hand, making it easier for the hitter to coordinate movements and master the inertia of the cue stick. If the center of gravity is not well done, it is possible that the center of gravity is too far back, the back hand is too heavy, and the tip of the cue floats. On the contrary, if the center of gravity is too far forward, the back hand floats. Therefore, the detection of the center of gravity of the cue stick is particularly important. Content of the Utility Model
[0004] The main purpose of the utility model is to provide a center of gravity detection device for a cue stick, which can effectively solve the problems in the background technique.
[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0006] A center of gravity detection device for a cue stick, including a workbench. A first support foot and a second support foot are respectively installed at the front part and the rear part of the lower end of the workbench. An adjustment frame is inserted and installed in the middle of the upper end of the workbench. A detection device is installed at the upper end of the adjustment frame. A marking device is fixedly installed at the front end of the detection device. A support device is fixedly installed at the left part and the right part of the upper end of the workbench.
[0007] Preferably, the detection device includes a motor and a fixed seat. A threaded rod is fixedly installed at the output end of the motor. A slider is installed on the outer surface of the threaded rod. A support frame is installed at the upper end of the slider. A first electric telescopic rod is installed at the upper end of the fixed seat. The output end of the first electric telescopic rod is fixedly connected to the adjustment frame. The fixed seat is fixedly installed at the middle of the rear end of the first support leg. A chute is opened at the upper end of the adjustment frame. The threaded rod is rotatably installed in the chute. The motor is installed at the right end of the adjustment frame. The adjustment frame and the support frame thereon are lifted by the first electric telescopic rod. The support frame then lifts the cue on the two support seats. When the cue sways left and right, it proves that this point is not the center of gravity. The first electric telescopic rod retracts, and the cue falls back onto the two support seats. Then, the motor drives the threaded rod to rotate in the chute. At this time, the slider on the outer surface of the threaded rod adjusts left and right accordingly, so that the support frame is adjusted accordingly. Then, repeat the above detection steps until the two ends of the cue reach balance when the cue is lifted by the support frame. At this time, the position of the support frame is the center of gravity of the cue.
[0008] Preferably, the marking device includes a connecting seat. A second electric telescopic rod is installed at the upper part of the front end of the connecting seat. The output end of the second electric telescopic rod is fixedly installed with a mounting sleeve. A marking pen is installed in the mounting sleeve. The connecting seat is fixedly installed at the front end of the support frame. The mounting sleeve is pushed by the second electric telescopic rod, and the marking pen on the mounting sleeve makes a mark on the cue. This point is the center of the cue, which facilitates people to quickly find the center of gravity of the cue subsequently.
[0009] Preferably, the supporting device includes a first support seat and a second support seat. Placing grooves are opened at the upper ends of the first support seat and the second support seat. Both the first support seat and the second support seat are designed in an L shape. When the cue is placed therein, it can limit the two ends of the cue to prevent the cue from shifting.
[0010] Preferably, the shape of the connecting seat is L-shaped.
[0011] Preferably, the first support seat and the second support seat are symmetrically distributed left and right in position.
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] 1. When the center detection of the cue is required, place the two ends of the cue on the first support base and the second support base on the support device respectively. Both the first support base and the second support base are designed in an L shape. When the cue is placed inside, it can limit the two ends of the cue to prevent the cue from shifting. Then, use the first electric telescopic rod on the detection device to lift the adjustment frame and the support frame thereon. The support frame then lifts the cue on the two support bases accordingly. When the cue sways left and right, it proves that this point is not the center of gravity. The first electric telescopic rod retracts, and the cue falls back onto the two support bases. Then, drive the threaded rod to rotate in the chute by the motor. At this time, the slider on the outer surface of the threaded rod adjusts left and right accordingly, so that the support frame is adjusted accordingly. Then, repeat the above detection steps until the two ends of the cue reach balance when the cue is lifted by the support frame. At this time, the position of the support frame is the center of gravity of the cue.
[0014] 2. After the center of gravity of the cue is detected, use the second electric telescopic rod on the marking device to push the installation sleeve, and the marker pen on the installation sleeve makes a mark on the cue. This point is the center of the cue, which is convenient for people to quickly find the center of gravity of the cue subsequently. Description of the Drawings
