Description

Technical Field

[0001] The present invention relates to the technical field of billiard cues, and particularly to a billiard cue with impact extension and acceleration. Background Art

[0002] With the development of society, people's living standards are constantly improving, and more and more people pay attention to the quality of life. As a recreational sport, billiards is becoming more and more popular among modern people. A billiard cue is a tool for hitting the ball in billiards. Conventional billiard cues usually consist of a tip, a ferrule, and a shaft. In order to increase the hitting force of the billiard cue, in the prior art, a structure capable of increasing the hitting force is generally provided on the shaft. For example, the patent document with the application number CN201620966955.7 discloses a billiard cue capable of increasing the impact force. Although it can increase the impact force of the cue by means of an impact block and a spring arranged inside the front shaft, the increased impact force is limited, and the impact block is connected by a spring, so the working stability is poor. Also, for example, the patent document with the application number CN201720286670.3 discloses a nested elastic billiard cue, and the patent document with the application number CN200920263817.2 discloses an automatic billiard cue. The former belongs to manual control to achieve automatic hitting of the billiard cue, and the latter belongs to electric control to achieve automatic hitting of the billiard cue. Although both can increase the impact force, neither can achieve secondary power generation, so the hitting force cannot be further increased. Therefore, the defects are very obvious, and a solution is urgently needed. Summary of the Invention

[0003] In order to solve the above technical problems, the purpose of the present invention is to provide a billiard cue with impact extension and acceleration.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

An embedding hole is opened at the front end of the front rod, and the rear end of the front rod is detachably connected to one end of the rear handle. The impact ejection acceleration mechanism includes an embedding cylinder embedded in the embedding hole, an ejection acceleration cylinder slidably connected to the inner cavity of the embedding cylinder, a shaft rod slidably penetrating through the front end face of the ejection acceleration cylinder, a striking plate connected to the front end of the shaft rod, a leather head connected to the striking plate, a conical block connected to the rear end of the shaft rod and slidably arranged in the ejection acceleration cylinder, a clamping block connected to the middle of the ejection acceleration cylinder and located inside the ejection acceleration cylinder, an ejection driver arranged in the embedding cylinder and drivingly connected to the rear end of the clamping block, a vertical rod arranged in the embedding cylinder, and a plurality of elastic claws arranged at one end of the vertical rod close to the conical block. The conical block is located in front of the clamping block, and each elastic claw is provided with a contact inclined surface slidably abutted against the conical surface of the conical block. A clamping space for clamping the clamping block is surrounded by the plurality of elastic claws; the conical block is used to drive the plurality of elastic claws to open outwards; the front end of the ejection acceleration cylinder can protrude outside the front end of the embedding hole; when the clamping block is clamped in the clamping space, the plurality of elastic claws approach each other, the conical block protrudes between the contact inclined surfaces of the plurality of elastic claws, and there is an activity space between the striking plate and the front end face of the embedding cylinder or / and the front end face of the ejection acceleration cylinder.

[0006] Further, an internal thread section is provided on the inner side wall of the embedding hole, and an external thread section is provided on the outer side wall of the embedding cylinder. The external thread section is used for threaded connection with the internal thread section.

[0007] Further, a limit ring is provided at the front end of the embedding cylinder, and the limit ring is used to abut against the front end face of the front rod.

[0008] Further, the ejection driver is a spring. The spring is sleeved outside the vertical rod, and the two ends of the spring respectively abut against the rear end face of the clamping block and the inner bottom wall of the embedding cylinder.

[0009] Further, a slider is provided on the outer side wall of the ejection acceleration cylinder, and a limit groove is provided on the inner wall of the embedding cylinder. The slider is slidably arranged in the limit groove.

[0010] Further, a contact rod is installed on the vertical rod, and the plurality of elastic claws are circumferentially distributed around the contact rod. The contact rod and the plurality of elastic claws surround to form a clamping space.

[0011] Further, a radial through hole penetrating the inner cavity of the ejection acceleration cylinder is opened in the middle of the ejection acceleration cylinder, and the clamping block is installed in the radial through hole.

[0012] Further, a stud is provided at one end of the vertical rod away from the elastic claws, and a threaded hole is provided on the rear end face of the embedding cylinder. The stud is in threaded connection with the threaded hole.

[0013] Further, a shaft section is connected to the front end of the conical block. The shaft section is slidably connected to the inner wall of the ejection acceleration cylinder, and the shaft section is in threaded connection with the shaft rod.

[0014] Furthermore, a guide inclined surface for abutting against the abutting inclined surface is provided at the front end of the clamping block.

[0015] The beneficial effects of the present invention are as follows: in practical application, when the billiard cue is in the initial state, the clamping block is clamped in the clamping space, a plurality of elastic clamping claws are close to each other, and the abutting inclined surfaces of the plurality of elastic clamping claws apply extrusion force to the conical surface of the conical block, and under the cooperation of the abutting inclined surface and the conical surface of the conical block, the conical block is limited between the abutting inclined surface and the inner end surface of the ejection acceleration cylinder, the ejection drive is in the ejection energy storage state, and the activity space provides compression space for the leather head when it hits the billiard ball. When hitting the billiard ball, when the leather head hits the billiard ball, the billiard ball applies a reverse force to the leather head, and this reverse force causes the leather head to move backward together with the striking plate, the shaft rod and the conical block, and reduces the activity space. The conical block moving backward will apply an extrusion force to the contact inclined surfaces of multiple elastic claws, and as the conical block moves backward, the multiple elastic claws will open and release the clamping block. At this time, the ejection drive instantly releases the ejection driving force to drive the clamping block to move forward. The forward-moving clamping block disengages from the clamping space and drives the ejection acceleration cylinder to move forward by a preset stroke, so that one end of the ejection acceleration cylinder protrudes out of the embedded cylinder, and the forward-moving clamping block will resist the conical block, the shaft rod, the striking plate and the leather head to move forward, so that the leather head can apply a secondary force to the billiard ball to increase the striking force of the leather head hitting the billiard ball, thereby achieving the effect of adding force to hit the billiard ball and increasing the moving speed of the billiard ball. After hitting the ball, when it is necessary to restore the billiard cue to the ejection energy storage state, a backward pressing force is applied to the leather head, so that the leather head, the striking plate, the shaft rod and the tapered block move backward, and the activity space gradually shrinks. The tapered block moving backward contacts the clamping block and drives the clamping block and the ejection acceleration cylinder to move backward. As the clamping block and the tapered block move backward, the conical surfaces of the clamping block and the tapered block contact the contact inclined surfaces of multiple elastic claws, causing the multiple elastic claws to gradually open until the clamping block moves into the clamping space and the ejection acceleration cylinder is ejected. When the ejection acceleration cylinder is reset, multiple elastic claws approach each other under the action of the rebound force and clamp the clamping block in the clamping space, and the contact slopes of the multiple elastic claws approaching each other will apply extrusion force to the conical surface of the conical block, so that the conical block, together with the shaft and the striking plate, moves forward to reset, so that the conical block is limited between the contact slope and the inner wall of the ejection acceleration cylinder, and there is a movable space between the striking plate and the front end surface of the embedded cylinder or / and the front end surface of the ejection acceleration cylinder, so as to facilitate the next force-added impact on the billiard ball. The present invention has a simple structure, manual reset, and is easy to use. It can achieve a secondary force-added impact on the billiard ball based on the original impact force of the billiard ball, greatly increasing the hitting force and improving the moving speed of the billiard ball.

[0021] For the convenience of understanding by those skilled in the art, the present invention will be further described below in conjunction with embodiments and the accompanying drawings. The content mentioned in the implementation manners does not limit the present invention.

[0022] As Figures 1 to 3As shown in the figure, a billiard cue with impact extension and acceleration provided by the present invention includes a front rod 1, a rear handle 2 and an impact ejection acceleration mechanism 3. An embedding hole 4 is formed at the front end of the front rod 1. The rear end of the front rod 1 is detachably connected to one end of the rear handle 2. The impact ejection acceleration mechanism 3 includes an embedding cylinder 5 embedded in the embedding hole 4, an ejection acceleration cylinder 6 slidably connected to the inner cavity of the embedding cylinder 5, a shaft rod 7 slidably penetrating through the front end face of the ejection acceleration cylinder 6, a striking plate 8 connected to the front end of the shaft rod 7, a leather tip 9 connected to the striking plate 8, a conical block 10 connected to the rear end of the shaft rod 7 and slidably arranged in the ejection acceleration cylinder 6, a clamping block 11 connected to the middle of the ejection acceleration cylinder 6 and located inside the ejection acceleration cylinder 6, an ejection driver 12 arranged in the embedding cylinder 5 and drivingly connected to the rear end of the clamping block 11, a vertical rod 13 arranged in the embedding cylinder 5, and a plurality of elastic claws 14 arranged in a circular array at one end of the vertical rod 13 close to the conical block 10. The plurality of elastic claws 14 protrude into the ejection acceleration cylinder 6; the front end of the embedding cylinder 5 is open and the rear end is closed; the front end of the ejection acceleration cylinder 6 is closed and the rear end is open; the embedding cylinder 5 is sleeved outside the ejection acceleration cylinder 6; the conical block 10 is located at the front end of the clamping block 11. Each elastic claw 14 is provided with a contact inclined surface 15 slidably abutted against the conical surface of the conical block 10. A clamping space 16 for clamping the clamping block 11 is defined by the plurality of elastic claws 14; the conical block 10 is used to drive the plurality of elastic claws 14 to open from each other; the front end of the ejection acceleration cylinder 6 can protrude outside the front end of the embedding hole 4; when the clamping block 11 is clamped in the clamping space 16, the plurality of elastic claws 14 approach each other, the conical block 10 protrudes between the contact inclined surfaces 15 of the plurality of elastic claws 14, and there is a movable space 17 between the striking plate 8 and the front end face of the embedding cylinder 5 or / and the front end face of the ejection acceleration cylinder 6.

[0023] In actual application, when the billiard cue is in the starting state, the clamping block 11 is clamped in the clamping space 16, the multiple elastic claws 14 are close to each other, and the contact slopes 15 of the multiple elastic claws 14 apply extrusion force to the conical surface of the conical block 10. Under the cooperation of the contact slopes 15 and the conical surface of the conical block 10, the conical block 10 is limited between the contact slopes 15 and the inner end surface of the ejection acceleration cylinder 6, the ejection drive 12 is in the ejection energy storage state, and the activity space 17 provides compression space for the leather head 9 when it hits the billiard ball. When hitting the billiard ball, when the leather head 9 hits the billiard ball, the billiard ball applies a reverse force to the leather head 9, and the reverse force causes the leather head 9 to move backward together with the striking plate 8, the shaft 7 and the conical block 10, and the activity space 17 is reduced. The conical block 10 moving backward will apply a squeezing force to the abutting inclined surfaces 15 of the multiple elastic claws 14, and as the conical block 10 moves backward, the multiple elastic claws 14 will open and release the clamping block 11. At this time, the ejection drive 12 instantly releases the ejection drive force to drive The movable clamping block 11 moves forward, and the clamping block 11 moving forward is disengaged from the clamping space 16 and drives the ejection acceleration cylinder 6 to move forward by a preset stroke, so that one end of the ejection acceleration cylinder 6 protrudes out of the embedded cylinder 5, and the clamping block 11 moving forward will resist the conical block 10, the shaft 7, the striking plate 8 and the leather head 9 to move forward, so that the leather head 9 can apply a secondary force to the billiard ball to increase the striking force of the leather head 9 hitting the billiard ball, thereby achieving the effect of adding force to hit the billiard ball and increasing the moving speed of the billiard ball. After hitting the ball, when it is necessary to restore the cue stick to the ejection energy storage state, a backward pressing force is applied to the leather head 9, so that the leather head 9 moves backward together with the striking plate 8, the shaft 7 and the tapered block 10, and the activity space 17 gradually shrinks. The tapered block 10 moving backward contacts the clamping block 11 and drives the clamping block 11 and the ejection acceleration cylinder 6 to move backward. As the clamping block 11 and the tapered block 10 move backward, the conical surfaces of the clamping block 11 and the tapered block 10 will contact the contact inclined surfaces 15 of the multiple elastic claws 14, so that the multiple elastic claws 14 gradually open until the clamping block 11 moves to the clamping space 16. In the ejection acceleration cylinder 6, the ejection acceleration cylinder 6 is reset, and the multiple elastic claws 14 are brought close to each other under the action of the rebound force and the clamping block 11 is clamped in the clamping space 16, and the contact slope 15 of the multiple elastic claws 14 that are close to each other will apply a squeezing force to the conical surface of the conical block 10, so that the conical block 10 together with the shaft 7 and the striking plate 8 move forward to reset, so that the conical block 10 is limited between the contact slope 15 and the inner wall of the ejection acceleration cylinder 6, and there is a movable space 17 between the striking plate 8 and the front end surface of the embedded cylinder 5 or / and the front end surface of the ejection acceleration cylinder 6, so as to facilitate the next force-added impact on the billiard ball. The present invention has a simple structure, manual reset, and is easy to use. It can achieve a secondary force-added impact on the billiard ball based on the original impact force of the billiard ball, greatly increasing the hitting force and improving the moving speed of the billiard ball.

[0024] In this embodiment, the inner wall of the embedding hole 4 is provided with an internal thread section, and the outer wall of the embedding tube 5 is provided with an external thread section 18, and the external thread section 18 is used for threaded connection with the internal thread section. This structural design facilitates the disassembly and maintenance of the embedding tube 5 and the front rod 1, and the connection is firm. In addition, the structure of the front rod 1 and the embedding tube 5 is compact, which reduces the exposed area of ​​the embedding tube 5 and plays a protective role on the impact ejection acceleration mechanism 3.

[0025] In this embodiment, a limiting ring 19 is provided at the front end of the embedding tube 5, and the limiting ring 19 is used to abut against the front end surface of the front rod 1. During assembly, the limiting ring 19 abuts against the front end surface of the front rod 1 to limit the installation of the embedding tube 5, ensuring that the embedding tube 5 is installed in place, while preventing the embedding tube 5 from being excessively installed into the embedding hole 4, preventing the screw thread from being damaged, and also preventing the impact ejection acceleration mechanism 3 from not being able to work normally.

[0026] In this embodiment, the ejection driver 12 is a spring, which is sleeved outside the vertical rod 13, and the two ends of the spring respectively contact the rear end surface of the clamping block 11 and the inner bottom wall of the embedded tube 5. When the clamping block 11 is clamped in the clamping space 16, the spring is in a state of compression and storing elastic potential energy; when the multiple elastic claws 14 are opened, the clamping block 11 is separated from the clamping space 16 and moves forward under the action of the spring's rebound force. In the process of the spring expansion and contraction, the vertical rod 13 plays a role in limiting and guiding the spring, thereby improving the working stability of the spring.

[0027] In this embodiment, a slider is provided on the outer wall of the ejection acceleration cylinder 6, and a limiting groove is provided on the inner wall of the embedded cylinder 5, and the slider is slidably arranged in the limiting groove. During the reciprocating movement of the ejection acceleration cylinder 6, the slider moves along the path of the limiting groove, which improves the movement stability of the ejection acceleration cylinder 6 relative to the embedded cylinder 5 on the one hand, and ensures that the ejection acceleration cylinder 6 reciprocates within a preset stroke on the other hand.

[0028] In this embodiment, the vertical rod 13 is equipped with a resistance rod 20, and a plurality of elastic claws 14 are distributed around the resistance rod 20. The resistance rod 20 and the plurality of elastic claws 14 are arranged to form a clamping space 16. When the clamping block 11 moves into the clamping space 16 and collides with the resistance rod 20, it is proved that the clamping block 11 is clamped in the clamping space 16, and the billiard cue is in a state of ejection and energy storage. When the clamping block 11 collides with the resistance rod 20, the user feels the touch, which proves that the operation is in place, ensuring that the clamping block 11 can be stably clamped in the clamping space 16.

[0029] In this embodiment, a radial through hole 25 penetrating the inner cavity of the ejection acceleration cylinder 6 is opened in the middle of the ejection acceleration cylinder 6, and the clamping block 11 is installed in the radial through hole 25. This structural design facilitates the disassembly and maintenance of the clamping block 11, and also facilitates the overall assembly of the impact ejection acceleration mechanism 3, and reduces the difficulty of processing the ejection acceleration cylinder 6 and the clamping block 11.

[0030] In this embodiment, a stud 21 is provided at one end of the vertical rod 13 away from the elastic claw 14, and a threaded hole 22 is provided on the rear end face of the embedding cylinder 5. The stud 21 is threadedly connected to the threaded hole 22. This structural design facilitates the disassembly, assembly and maintenance of the bottom wall of the vertical rod 13 and the embedding cylinder 5, and the connection is firm.

[0031] Specifically, the multiple elastic claws 14 and the vertical rod 13 are of an integral structure, which is convenient for processing and forming, and makes the connection between the elastic claws 14 and the vertical rod 13 firm, and the structural stability is good.

[0032] In this embodiment, a shaft section 23 is connected to the front end of the conical block 10. The shaft section 23 and the conical block 10 are of an integral structure. The shaft section 23 is slidably connected to the inner wall of the ejection acceleration cylinder 6. During the reciprocating movement of the shaft rod 7, the shaft section 23 is slidably matched with the inner wall of the ejection acceleration cylinder 6, which improves the movement stability of the shaft rod 7. In addition, the shaft section 23 is threadedly connected to the shaft rod 7, which is convenient for the connection between the shaft rod 7 and the conical block 10, and the disassembly, assembly and maintenance are convenient, and the connection is firm.

[0033] In this embodiment, a guiding inclined surface 24 for abutting against the abutting inclined surface 15 is provided at the front end of the clamping block 11. During the process of the clamping block 11 moving forward out of the clamping space 16, the guiding inclined surface 24 abuts against the abutting inclined surface 15, which is beneficial to the clamping block 11 disengaging from the clamping space 16, so that the clamping block 11 drives the ejection acceleration cylinder 6 to move forward.

[0034] All the technical features in this embodiment can be freely combined according to actual needs.

[0035] The above embodiments are the preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution of the present invention is within the protection scope of the present invention.
