Detailed Description

Fig. 1 shows a structure of a conventional egg twisting machine.

The egg twisting machine in figure 1 comprises an egg twisting toy accommodating bin 1, a knob 2, an egg twisting taking-out opening 3, an egg twisting channel 4, a base 5 and an egg twisting 6. In fig. 1, after the user pays out the token, the electronic token or the code scanner, the twisted eggs in the twisted egg toy accommodating bin will drop one by one along the twisted egg channel by turning the knob 2.

Fig. 2 and 3 show a driving structure diagram of the egg twisting machine shown in fig. 1. In fig. 2 and 3, the dial wheel 17 is driven by a rotating force to drive the dial wheel 15 to rotate, the dial wheel 15 applies a force to the dial teeth 18, and the dial teeth 18 drive the egg-twisting turntable 20 to rotate after being stressed. The egg twisting turntable 20 is provided with a plurality of holes 19, and if n holes are provided (5 holes in the figure), after the egg twisting turntable 20 rotates 360/n degrees (360/5 is 72 degrees in the figure), the egg twisting toy reaches the position of the inlet 13 of the egg twisting channel under the driving of the holes 19.

The problem of the egg twisting machine in the prior art is that the egg twisting machine is unlocked after the egg twisting machine receives successful payment. Generally speaking, one twist toy can be obtained by rotating the handle 360 degrees for one payment, so as to drive the twist-egg turntable 20 to rotate 360/n degrees, but in some cases, the lock fails, and the player can rotate the handle to drive the twist-egg turntable 20 to rotate more than 360/n degrees, so that the possibility of obtaining two twist toys by one payment exists.

Figure 4 shows a schematic view of the lock of the present invention.

The locking plate may also be provided with a plurality of ratchet teeth 306, the pawl 305 being spring biased towards the ratchet teeth 306. As shown in fig. 4, the locking plate may be rotated counterclockwise; the locking plate in fig. 4 cannot rotate in the clockwise direction due to the action of the pawl and the spring. If desired, the locking plate may be reversed after changing the shape of the ratchet and pawl.

The locking plate is provided with a plurality of locking slots, shown in fig. 4 as 302, 303 and 304, respectively. The utility model discloses a set up a plurality of locking grooves to can realize preventing that lockplate from excessively rotating.

In fig. 4, the locking groove must be able to accommodate the bolt, and therefore the width of the locking groove (which can also be expressed in circumferential angle relative to the centre of rotation) must be greater than the diameter of the bolt. After the amusement player pays successfully and rotates to obtain the twisted egg, the lock tongue is positioned in the locking groove, but the locking plate can still rotate by a certain angle at the moment, so that the shifting teeth on the shifting wheel are driven to rotate by a certain angle, and the twisted egg rotary table 20 can also rotate under the driving of the shifting teeth. When the knob is turned once, the poking wheel pushes the egg twisting turntable to rotate by 360/n, wherein n is the number of the holes 19 of the egg twisting turntable for dropping the twisted eggs.

Because the poking wheel mechanism is adopted to push the egg twisting turntable to rotate, after the player twists the knob for a plurality of times, the position of the locking disc is no longer at the position of the midpoint and can generate certain offset, so that the position of the egg twisting turntable can also generate certain change; under normal conditions, the egg twisting rotary disc 19 is rotated for 360/n degrees to drop a twisted egg, and due to the deviation of the position of the locking disc (shown in figure 5), the situation that the twisted egg needs to be rotated for more than 360/n degrees to drop the twisted egg occurs.

When the situation that the egg needs to be turned over and the egg falls over 360/n degrees, the sensor in the egg outlet channel senses that the twisted egg falls and gives a signal for locking the egg turning plate, and if only one locking groove is formed in the locking plate, the position corresponding to the locking tongue is probably not the locking groove. If the egg twisting machine gives a locking signal to the lock tongue, but the position of the locking disc deviates, the lock tongue only props against the locking plate, and the lock tongue cannot complete locking; in this case, although the egg twister instructs the lock plate to be locked by the lock tongue, the lock plate is not locked, so the player can continue to twist the knob until the lock plate is rotated to the lock tongue position; in the process, the egg twisting turntable rotates a certain angle again, so that an egg twisting toy can fall off again.

As shown in fig. 4 and 5, the locking plate of the present invention is provided with two or more locking grooves. When the position of the locking plate is deviated (the deviation angle is shown in fig. 5), the user is required to twist more than the knob, so that the twisting angle of the egg twisting rotary plate exceeds 360/n degrees, and in this case, the lock tongue may miss the position of the first locking groove 302; but since the egg is also provided with the second locking groove 303 and even the third locking groove 304, the locking tongue can be ensured to lock the locking plate at a next locking position.

The circumferential angles corresponding to the

locking grooves

302, 303 and 304 are 15-20 degrees, 10-15 degrees and 5-10 degrees.

Because the bolt can be guaranteed to be correctly positioned in the locking groove, the situation that the locking plate is propped by the bolt does not occur. The latch bolt can be pushed by a linear motor or a cam mechanism, and if the latch bolt is propped, the service life of the motor and a mechanical structure is reduced. The utility model prolongs the service life of the locking plate and the lock tongue, and the service life of the torsion knob and the shifting wheel; meanwhile, the locking plate can not rotate for two circles, so that the problem of twisting out two egg-twisting toys by paying once is fundamentally solved.

The utility model discloses a lock can be used for the locking knob of turning round the egg ware, also should lock and the coaxial fixed setting of knob promptly. If the external knob transmits power to the egg twisting turntable through the one-way transmission mechanism, the lock does not need to be provided with a ratchet mechanism; for example, the external knob transmits power to the egg twisting turntable through a worm gear mechanism. If the external knob transmits power to the egg twisting turntable through a gear mechanism or a dial wheel and other mechanisms which do not prevent rotation, a ratchet and a pawl can be arranged on the lock, so that the handle of the egg twisting machine is prevented from rotating; if the handle of the egg twisting machine can rotate, the player can obtain two opportunities of twisting eggs through one-time payment by rotating for a certain angle.

The lock of the utility model can also be used for locking the egg twisting rotary disc or other situations with rotary motion.

The utility model discloses the excessive rotatory problem of solution lockplate that can be low-cost.

The foregoing is a more detailed description of the present invention, taken in conjunction with the specific preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described. To the utility model belongs to the technical field of ordinary technical personnel, do not deviate from the utility model discloses under the prerequisite of design, can also make a plurality of simple deductions or replacement, all should regard as belonging to the utility model discloses a protection scope.
