Description

Mahjong piece scraping bar of mahjong machine at half speed

Technical Field

The utility model is applied to the shuffling barrel of the mahjong machine.

Background

The mahjong machine becomes an indispensable facility for playing mahjong by people at present, and the mahjong machine in the prior art has the disadvantages of difficult production and assembly due to the rotation of the mahjong scraping strips or complex structure and poor practicability; or the rotary scraping strip is driven by the steel ball, because the steel ball, the large disc and the rotary cover are in point contact, the contact area is too small, the large disc and the rotary cover are easy to wear after long-term use, the steel ball slips and generates squealing and abnormal sound phenomena, the rotation speed of the scraping strip can not be effectively controlled, the working efficiency of the mahjong machine is reduced, and the possibility of failure occurrence is increased.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems, the utility model designs a half-speed rotary card scraping strip, which comprises a fixed tooth, a card scraping strip, a small bevel gear, a big disc and a straight shaft seat;

the fixed teeth are composed of a fixed cylinder and conical teeth, the conical teeth are annularly positioned at the bottom of the fixed cylinder, the tooth surface of the conical teeth is downward, the center of the fixed cylinder is vertically communicated, and the inner wall of the fixed cylinder is provided with a thread, and the side surface of the thread is provided with a locking hole;

the card scraping strip is composed of a disc seat and a plurality of scraping strips, the scraping strips are arc-shaped, the root parts of the scraping strips are evenly distributed around the disc seat and extend outwards, the center of the disc seat is a circular hole, a plurality of conical tooth grooves are evenly distributed around the circular hole, and the conical tips of the small conical teeth face the center of the circular hole and are placed in the conical tooth grooves through tooth shafts;

the center of the surface of the large disc is provided with a mounting round hole, and a conical tooth structure with an upward tooth surface is arranged around the round hole; the upper surface of the straight shaft seat is cylindrical, the surface of the straight shaft seat is provided with threads, and the bottom surface of the straight shaft seat is provided with a fixing plate;

the straight shaft seat is fixed with the base plate through the fixing plate, the fixing teeth, the card scraping strip and the large disc are sleeved on the straight shaft seat sequentially through respective mounting holes from top to bottom, the fixing teeth are fixed with the straight shaft through locking holes by screws, and the small conical teeth are meshed with the fixing teeth and the large disc respectively to form a linkage structure.

The conical teeth on the bottom surface of the fixed tooth are preferably conical surfaces without teeth, the small conical teeth are round table-shaped rolling shafts, and the conical surfaces without teeth are arranged around the round hole in the middle of the large disc.

Detailed Description

In order to clearly illustrate the technical solutions of the present invention or the prior art, the following will further describe the implementation of the present invention with reference to fig. 1-6, and the described embodiment is only an embodiment of the present invention, not all embodiments, and the embodiments obtained by simple modification by those skilled in the art or others without creative efforts belong to the protection scope of the present invention.

The fixed teeth 1 are composed of a fixed cylinder 11 and conical teeth 12, the conical teeth are annularly positioned at the bottom of the fixed cylinder, the tooth surface of the conical teeth is downward, a cylinder which is communicated from top to bottom is arranged in the middle of the fixed teeth, threads are arranged on the inner wall of the cylinder, and locking holes 13 are formed in the side surface of the cylinder wall;

the card scraping strip 2 consists of a disc seat 21 and a plurality of scraping strips 22, the scraping strips are arc-shaped and evenly distributed around the disc seat 21 and extend outwards, the center of the disc seat 21 is a circular hole, and a plurality of conical tooth grooves 23 are evenly distributed around the circular hole; the conical tip of the small conical tooth 5 faces the center of the round hole and is arranged in the tooth groove 23 through the tooth shaft 6;

the central part of the large disc 3 is a round hole, and a conical tooth 32 structure with an upward tooth surface is arranged around the round hole; the surface of the cylinder 41 on the upper surface of the straight shaft seat 4 is provided with threads, and the bottom surface is provided with a fixing plate 42;

fig. 6 is a schematic view showing that the straight shaft seat 4 is fixed to the base plate through the fixing plate 42, the fixed teeth 1, the card scraping bar 2 and the large disc 3 are sleeved on the straight shaft 41 through respective mounting holes in sequence from top to bottom, the fixed teeth 1 are fixed to the straight shaft 41 through the locking holes 13 by screws, and the small bevel teeth 5 are engaged with the fixed teeth 1 and the large disc 3 to form an interlocking structure.

When the mahjong machine works, the shuffling disc 3 rotates, and the small bevel gear 5 is driven to rotate around the circle center of the scraping bar disc 21 through the meshing linkage structure, so that the scraping bar disc 2 is driven to rotate. Because the scheme is a bevel gear meshing structure, the fixed teeth 1 are fixed relative to the large disc 3, the rotating speed of the card scraping strip 2 is one half of that of the large disc 3, and sliding and abnormal sound cannot be generated; meanwhile, the contact area between the small bevel gear 5 and the bevel gear 12 and between the large disc bevel gear 32 is large, so that the loss caused by friction between the bevel gears is reduced, and the service life of the card scraping strip is prolonged.
