DETAILED DESCRIPTION

[0028] 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.

[0029] like Figure 1-Figure 6 As shown, the utility model discloses a double reset mechanism based on gravity and elasticity, combined with Figure 1 , Figure 2 , which comprises: an upper frame 1, a first driving wheel set 11 and a second driving wheel set 12 are respectively installed at the front and rear ends of the upper frame 1, and a driving motor 10 drives the first driving wheel set 11 through a chain 14;

[0030] A guide rail 15 is installed in the upper frame 1, and the guide rail 15 is connected to the moving component 2. The moving component 2 is connected to the first and second driving wheel groups through a chain 14. Figure 3 As shown, a plurality of oscillating line wheel assemblies 22 are installed in the moving assembly 2, and the oscillating line wheel assembly 22 is provided with an oscillating line wheel 222;

[0031] Combination Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, an elastic reset assembly 3 is installed at the rear end of the upper frame 1, the installation height of the elastic reset assembly 3 is greater than the installation height of the moving assembly 2, a crossbeam 13 is installed in the upper frame, and the elastic reset assembly 3 is provided with a second rotating shaft 31, and a plurality of main line wheel assemblies 30 are rotatably installed on the second rotating shaft 31;

[0032] The main line wheel assembly 30 is provided with a second line wheel bracket 301, and the second line wheel bracket 301 is connected to the second rotating shaft 31 through a second connecting through hole 302. A spring fixing part 303 is provided on the upper side of the second connecting through hole 302. The spring fixing part 303 is connected to one end of the spring 32, and the other end of the spring 32 is connected to the cross beam 13. The main line wheel is installed on the lower side of the second connecting through hole 302.

[0033] It should be noted that, combined with Figure 1 As shown, one end of the pull rope 6 starts from the elastic reset component 3, is then wound into the swing line wheel 222 of the moving component 2, is then wound into the locking rope component 4, is then wound into the lower line wheel 5 and is connected to the upper end of the ball pin, and the lower side of the lower line wheel is the bowling shaping room and the lane in turn.

[0034] When the pin moves upward, the driving motor 10 drives the moving assembly 2 to move away from the elastic reset assembly 3 through the chain 14, during which the elastic reset assembly 3 accumulates potential energy.

[0035] When the pin is lowered, the rope locking assembly 4 locks the corresponding pull rope, and then the pull rope pulls the moving assembly 2 close to the elastic reset assembly 3 under the action of the pin's own gravity and the elastic reset assembly 3, thereby lowering the pin.

[0036] Specifically, combined Figure 1 , Figure 2 As shown, a travel sensor 20 is installed in the upper frame 1, and the travel sensor 20 is used to detect the position of the moving component 2. The main control of the rope lifting device determines the current position of the moving component 2 through the travel sensor 20, and then judges the current state, so as to execute the rope locking, the driving of the driving motor and the control of other mechanisms.

[0037] Furthermore, a first baffle 101 is installed on the upper side of the second driving wheel group 12, and a second baffle 102 is installed on the lower side of the first and second driving wheel groups. The first baffle 101 is used to limit the upper height of the pull rope when it moves, and press the pull rope when necessary to avoid interference between adjacent pull ropes; the second baffle 102 is used to limit the lower height of the pull rope when it moves, and press the pull rope when necessary to avoid interference between adjacent pull ropes, thereby ensuring that the rope locking assembly 4 can smoothly release and retract the rope.

[0038] Specifically, Figure 3 As shown, the moving assembly 2 is provided with a first rotating shaft 21, the swing wire wheel assembly 22 is rotatably mounted on the first rotating shaft 21, and both ends of the first rotating shaft 21 are provided with a moving base 23, and the moving base 23 is connected to the guide rail 15;

[0039] Furthermore, the movable base 23 may be connected to the guide rail 15 via rollers to achieve smoother movement;

[0040] Combination Figure 3 , Figure 6 As shown, the oscillating wire wheel assembly 22 is provided with a first wire wheel bracket 220 , the first wire wheel bracket 220 is connected to the first rotating shaft 21 through a first connecting through hole 221 , and an oscillating wire wheel 222 is installed in the first wire wheel bracket 220 .

[0041] Specifically, combined Figure 5 As shown, the second wire wheel bracket 301 is provided with a pull rope limiting column 306, and the pull rope limiting column 306 is respectively arranged on the upper and lower sides of the main wire wheel;

[0042] The main line wheel comprises: an inner line wheel 304 and an outer line wheel 305. A limiting member 307 is provided on the second line wheel bracket 301. The limiting member 307 is used to limit the inner line wheel 304. The outer line wheel 305 is rotatably connected with the inner line wheel 304. One end of the pull rope is fixed on the outer line wheel 305.

[0043] A torsion spring 308 is provided between the inner line wheel 304 and the outer line wheel 305, and the two ends of the torsion spring 308 are fixedly connected to the inner line wheel 304 and the outer line wheel 305 respectively. When the outer line wheel 305 rotates in a set direction, the torsion spring 308 is compressed, so that the main line wheel itself has the ability to retract the draw rope.

[0044] Again, combined Figure 1 , Figure 2 As shown, a limit beam 16 is installed in the upper frame 1, and the limit beam 16 is arranged on one side of the elastic reset component 3. The limit beam 16 limits the rotation range of the second wire wheel bracket 301; two limit beams 16 are provided and are respectively arranged on the front and rear sides of the second wire wheel bracket 301. The purpose is to avoid faults by setting the rotation range of the second wire wheel bracket 301;

[0045] Among them, the setting of the limiting beam 16 at the rear sets the maximum length of the spring 32 being stretched, 1. Avoiding the spring 32 from being over-stretched, 2. Allowing the torsion spring 308 inside the main line wheel to be fully compressed, ensuring that the main line wheel has the ability to tension and pull the pull rope; the setting of the limiting beam 16 at the front sets the initial length of the spring 32 being stretched, 1. In the initial state, the spring 32 is in a stretched state, thereby enabling the component itself to have a tensioning and stretching effect; 2. In the initial state, the spring 32 is in a stretched state, avoiding the spring 32 from completely contracting and rebounding.

[0046] In summary, the utility model realizes active retraction of the pull rope through the driving motor, the moving assembly and other components, thereby achieving the purpose of pulling the bowling pins upward; when the pins need to be moved down and placed, they are quickly and stably lowered and reset through their own gravity and the elastic potential energy accumulated by the above-mentioned elastic reset assembly. During the lowering and resetting period, the elastic reset assembly cooperates with the moving assembly to keep the stretching in a tensioned state at all times, thereby avoiding the free fall of the pins and ensuring the stability of the pins being lowered; wherein, the elastic reset assembly pulls the moving assembly through its own gravity, spring and internal torsion spring, and then cooperates with the pins' own gravity to execute the pin lowering, ensuring that the mechanism can drive a single pin to move downward to meet various pin placement conditions.
