When a small number of points are deployed, the accuracy is not high and will be affected by the ambient light of the stadium.

[0005] Furthermore, although the existing mechanical rope lock can change the clamping force / stroke to avoid over-clamping the rope, it is still easy to clamp the rope or damage the limiter in the case of power overload.

[0024] In order to make the above-mentioned purposes, features and advantages of the utility model more understandable, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from this description, and those skilled in the art can make similar improvements without violating the connotation of the utility model. Therefore, the utility model is not limited by the specific embodiments disclosed below.

[0025] like Figure 1-Figure 3 As shown, the utility model discloses a rope lock detection mechanism, which comprises: a rope lock bracket 1, wherein the rope lock bracket 1 is equipped with a detection component 2, an electromagnet component 3 and a locking member 4;

[0026] The detection assembly 2 is provided with a detection wheel 20, a pull rope is wound around the detection wheel 20, a photoeye wheel 21 is provided on the detection wheel 20, a photoelectric sensor 22 is provided on one side of the photoeye wheel 21, and the photoelectric sensor 22 is used to detect the rotation of the photoeye wheel 21 and output a corresponding signal;

[0027] The rope lock bracket 1 is provided with an upper limit plate 11, the locking member 4 is located at the lower side of the upper limit plate 11, the lower end of the locking member 4 is a first connecting portion 40, the first connecting portion 40 is rotatably connected to the rope lock bracket 1, and the upper end of the locking member 4 is a locking portion 41, and the locking portion 41 cooperates with the upper limit plate 11 to clamp and lock the pull rope;

[0028] The electromagnet assembly 3 drives the movable member 30 to perform telescopic movement, and the movable member 30 drives the locking member 4 to rotate around the first connecting portion 40;

[0029] Furthermore, the center of gravity of the locking member 4 is not on the same vertical line as the first connecting portion 40, so in a natural state, the locking member 4 has a tendency to rotate sideways. When working, the locking member 4 is driven, and the locking portion 41 cooperates with the upper limit plate 11 to clamp and lock the pull rope.

[0030] It should be noted that the locking member 4 can be made of rubber, and the electromagnet assembly 3 is provided with an inductive / capacitive energy storage circuit. When the pull rope is threaded, it passes through the gap between the locking portion 41 and the upper limit plate 11, and is wound around the detection line wheel 20. When the pin is shot down, it will pull the pull rope to move, and the pull rope drives the detection line wheel 20 to rotate, and the detection line wheel 20 drives the photoeye wheel 21 to rotate, and the photoelectric sensor 22 detects the rotation of the photoeye wheel 21 and outputs a pulse signal corresponding to the number of photoeyes to the main control, and the main control obtains the pulse signal to determine whether the shot is shot down and to perform scoring.

[0031] Specifically, combined Figure 2 , Figure 3 As shown, the locking member 4 is provided with a second connecting portion 42, and the second connecting portion 42 is located between the first connecting portion 40 and the locking portion 41. The movable member 30 is connected to the second connecting portion 42 via the connecting member 31, and the connecting member 31 may be a spring, through which driving buffering is performed to protect each component.

[0032] Furthermore, the movable member 30 is connected / sheathed with a reset spring 32, and the movable member 30 is restored to an initial state by the reset spring 32. In the initial state, the locking member 4 and the upper limit plate 11 do not clamp the pull rope. The reset spring 32 plays a role of auxiliary reset and drive buffering, and the locking member 4 can also reset the movable member 30 under the action of gravity.

[0033] Specifically, Figure 1-Figure 3 As shown, the rope lock bracket 1 is provided with a lower limit plate 10, and the locking member 4 is located between the upper limit plate 11 and the lower limit plate 10, and the lower limit plate 10 is used to limit the rotation angle of the locking member 4. After the locking member 4 is reset, it will stretch the connecting member 31 (spring), at this time, the connecting member 31 (spring) will shake with the locking member 4, and the lower limit plate 10 is provided to reduce the amplitude of shaking and absorb energy, so as to prevent the locking member 4 from shaking for a long time.

[0034] Specifically, Figure 3 As shown, the rope locking bracket 1 is installed with a first guide member 12, which can be a wire wheel. The first guide member 12 is arranged on the lower side of the upper limit plate 11, and the first guide member 12 and the upper limit plate 11 form a rope threading groove, and the pull rope is placed in the rope threading groove.

[0035] Furthermore, the rope lock bracket 1 is provided with a second guide member 13, which is used for guiding the pull rope, and the second guide member 13 can be a U-shaped fork, through which the pull rope passes. The movement direction of the two ends of the pull rope is controlled by the first and second guide members.

[0036] In summary, the above-mentioned detection component detects the movement and movement length of the pull rope to determine whether the pin is knocked down by the bowling ball, thereby realizing the functions of pin fall judgment and scoring. Compared with the traditional detection method, it is more accurate and stable, and the detection component can be isolated from the ball room below, thereby avoiding the influence of ambient light on the detection; the above-mentioned electromagnet assembly is used to drive the locking piece to rotate, so as to achieve the clamping and locking of the pull rope and control the locking force, and the winding of the electromagnet assembly is used to cope with the instantaneous overload of the power supply, wherein the winding can be configured with an inductor / capacitor energy storage circuit to further cut the peak and realize the protection of the pull rope and equipment.
