Description

Technical Field

[0001] This utility model relates to the field of billiard cue technology, and in particular to an adjustable brass weighted end cap for a billiard cue. Background Technology

[0002] Existing cue sticks typically have a lead weight inserted at the butt to adjust the weight, or a copper block is used. The main purpose of cue weight adjustment is to adjust the center of gravity of the cue to achieve the specified weight and ensure the feel and stability of the shot. Weight adjustment ensures that the weight is evenly distributed between the front and back hands, making the cueing feel comfortable, thereby improving the accuracy and stability of the shot. However, the weight of the cue stick varies, and when fine-tuning the weight, the drilling depth needs to be controlled according to the weight of the lead weight. If the drilling is too deep or too shallow, the drilling needs to be deepened again, and broken lead weights and other patches need to be driven in. Therefore, controlling the weight adjustment based on the drilling depth and the weight of the lead weight requires a high level of craftsmanship from the manufacturer. Utility Model Content

[0003] Therefore, in view of the above problems, this utility model proposes an adjustable brass weight tail brass for billiard cues, which solves the technical problem of high manufacturing requirements for adjusting the weight by inserting a lead rod at the tail of the cue.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable brass counterweight tail brass for a billiard cue, comprising a cue body, an external thread on the outside of the cue body, an outer ring on the top of the cue body, an internal threaded hole inside the cue body, and an adjusting core that engages with the internal threaded hole. One side of the adjusting core is provided with a slot for engaging with an external screwdriver.

[0005] Furthermore, the slot is cross-shaped or hexagonal.

[0006] Furthermore, the outer ring has a cover hole on its top surface, and the outer ring is provided with a cover plate at the cover hole.

[0007] Furthermore, the adjusting core has an inner hole in the middle, an elastic sheet is provided in the inner hole, extension pieces are provided on both sides of the elastic sheet, inclined grooves for the extension pieces to be inserted are provided on both sides of the top of the inner hole, and a spring is provided at the bottom of the elastic sheet.

[0008] Furthermore, the angle between the inclined groove and the elastic sheet is 40 to 60 degrees.

[0009] Furthermore, the adjusting core has a lower groove in the middle that is smaller than the inner hole diameter.

[0010] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0011] This billiard cue features an adjustable brass weighted endplate. The cue body can be manufactured to a uniform size. A hole is drilled at the bottom of the cue, and then the cue body is inserted into the bottom. The cue body is preferably made of brass, a soft material that minimizes damage to the cue wood during insertion. After completion, the cue body is weighed. Adjustable cores of different lengths or numbers can be screwed into the threaded holes within the cue body to adjust the weight. This design simplifies the manufacturing process and eliminates the high technical requirements associated with traditional cue weight adjustments using a lead weight at the end.

[0016] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0017] refer to Figures 1 to 4 This embodiment provides an adjustable brass counterweight tail brass for a billiard cue, including a cue body 1, an external thread 2 on the outside of the cue body 1, an outer ring 3 on the top of the cue body 1, an internal thread hole 4 inside the cue body 1, and an adjustment core 5 that engages with the internal thread hole 4. One side of the adjustment core 5 is provided with a slot 6 for engaging with an external screwdriver.

[0018] Existing golf clubs typically use a lead weight at the butt to adjust the weight, or a copper block. However, the weight of the club varies, and when fine-tuning the weight, it is necessary to control the weight according to the drilling depth and the weight of the lead weight, which requires a high level of craftsmanship from the maker.

[0019] To ensure uniform dimensions, the shaft is made by drilling a hole in the bottom of the club and then inserting the shaft into the bottom. The shaft is preferably made of copper, which is soft and does not easily damage the wood when inserted into the bottom of the club. After completion, the shaft is weighed. Different lengths or numbers of adjustment cores can be screwed into the threaded holes in the shaft according to the weight of the shaft, making it easier to manufacture the club weight adjustment.

[0020] Users can adjust the weight according to their preferences. They can unscrew the adjustment core with an external screwdriver and then screw in the appropriate weight or stack adjustment cores to find the weight that suits their preferences. Compared with existing non-removable cues, this structure makes it easier for users to experience different weight cues on a single cue.

[0021] Some existing golf clubs have a hole drilled at the tail, a nut inserted, and then a bolt screwed into the nut for counterweight. However, once the nut-shaped counterweight is inserted into the club, the counterweight cannot be freely adjusted, and the nut-shaped counterweight has a large diameter, making the tail of the club prone to cracking and damage during processing and installation.

[0022] The slot 6 is cross-shaped or hexagonal. The slot shape can also be straight, quadrilateral or other existing shapes, which are highly versatile.

[0023] The outer ring 3 has a cover hole 7 on its top surface. The outer ring 3 is provided with a cover plate 8 at the cover hole 7. After the adjustment core is installed, the cover plate can be inserted into the cover hole to close the bottom of the rod body, improve the aesthetics, and prevent the adjustment core from falling off accidentally.

[0024] The adjusting core 5 has an inner hole 51 in the middle, and an elastic sheet 52 is provided in the inner hole 51. Extension pieces 53 are provided on both sides of the elastic sheet 52. The inner hole 51 has inclined grooves 54 on both sides of the top for the extension pieces 53 to be inserted. A spring 55 is provided at the bottom of the elastic sheet 52.

[0025] In use, first insert the elastic plate into the bottom of the inner hole, then release the elastic plate. Under the force of the bottom spring, the elastic plate will move upward. At the same time, use a tool to insert the extension pieces on both sides of the elastic plate into the inclined groove. Affected by the spring, as the elastic plate moves upward, it drives the extension pieces on both sides to pass through the inclined groove and contact the internal threaded hole on the inside of the club body, thus locking the adjusting core. Inserting the external screwdriver into the inner hole can automatically press the elastic plate down to the bottom. When the adjusting core is adjusted, when the external screwdriver is removed from the inner hole, affected by the spring, the elastic plate will lock into the internal threaded hole to fix the adjusting core, preventing the adjusting core from shaking and moving inside the club when it is hit and vibrated during use.

[0026] The angle between the inclined groove 54 and the elastic sheet 52 is 40 to 60 degrees, which facilitates the insertion of the extension sheet. Furthermore, under the influence of spring pressure, the extension sheets on both sides of the elastic sheet move more smoothly within the inclined groove.

[0027] The adjusting core 5 has a lower groove 56 in the middle that is smaller than the diameter of the inner hole 51. The lower groove helps to limit the position of the spring and prevent the spring from shaking.
