Abstract

The utility model relates to sports training equipment. A table tennis electromagnetic transmitter is characterized in that an armature cover (1) is arranged on the outer shell (4) of an electromagnet; a coil (3) is arranged in the outer shell (4); an armature (2) is arranged in the middle of the coil; an armature push rod (8) is fixedly connected on the armature (2); a reset spring (5) is sleeved on the push rod (8); a pole shoe (6) is arranged in the outer shell (4); a transmitting pipe (10) is connected on the outer shell (4); the front end of the armature push rod is provided with an impact head (9); and table tennis balls (11) are injected from an inlet (12) on the transmitting pipe (10). The joint between the outer shell (4) and the pipe (10) is provided with a universal joint (7). The coil is fed into adjusted pulse voltage, the pole shoe produces a strong magnetic field to attract the armature, push the push rod to be impacted forwards and transmit the table tennis balls; after the magnetic field disappears, the spring pushes the armature back to an original position, the coil is electrified again and the process is repeated again and again. Driven by a servo motor, the universal joint changes the transmitting direction and angle every time.

Description

A kind of table tennis electromagnetism transmitter

Technical field

The utility model belongs to the equipment of athletic training, a kind of specifically table tennis electromagnetism transmitter.

Background technology

The table tennis room of present athletic training venue, the table tennis transmitter of usefulness is to become different angles transmission table tennis with the motor rotation through the mechanism of complexity, its complex structure, the cost height, still artificial throwing trundles during the part table tennis training.Design a kind of simple in structurely, the electromagnetism transmitter that cost is low is necessary.

Summary of the invention

For overcoming the deficiencies in the prior art, the utility model proposes a kind of table tennis electromagnetism transmitter, it directly clashes into the transmission table tennis with the electromagnet rectilinear motion.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of table tennis electromagnetism transmitter, be provided with electromagnet, it is characterized in that armature lid (1) is installed on the shell (4) of electromagnet, shell (4) the inner chamber solenoid (3) of packing into, the armature (2) of packing in the coil (3), armature lifter (8) is connected on the armature (2), return spring (5) is enclosed within on the armature lifter (8), the electromagnet pole shoe (6) that will be provided with centre bore is again packed in the electromagnet casing (4), sending conduit (10) is connected on the electromagnet casing (4), the armature lifter front end is equipped with polyurethane bump head (9), table tennis inlet (12) injection that table tennis (11) is provided with from sending conduit (10).

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The utility model is specifically described by embodiment below in conjunction with accompanying drawing.

The specific embodiment

Shown in Figure 1, armature lid 1 is installed on the shell 4 of electromagnet, the shell 4 inner chambers solenoid 3 of packing into, the armature 2 of packing in the coil 3, armature lifter 8 is connected on the armature 2, and return spring 5 is enclosed within on the armature lifter 8, the electromagnet pole shoe 6 that will be provided with centre bore is again packed in the electromagnet casing 4, send conduit 10 and be connected on the electromagnet casing 4, the armature lifter front end is equipped with polyurethane bump 9, and table tennis 11 injects from the table tennis inlet 12 that sends conduit 10 and be provided with.

Electromagnet casing 4 is provided with universal joint 7 with the connecting portion that sends conduit 10.

Send into through adjusted pulse voltage for during work electromagnet coil 3, coil 3 gets the powerful magnetic field of electric generation, rapid adhesive armature 2, promote 9 impact forward of armature lifter 8 and bump, table tennis 11 is penetrated, following adjusted pulse voltage is zero, coil 3 dead electricity, magnetic field disappear, armature 2 is given reposition by return spring 5, next pulse voltage comes to launch again ... go round and begin again like this by instruction works, universal joint 7 changes the direction and the angle of each service under the drive of department's clothes small machine.
