TECHNICAL FIELD
[0001] The utility model relates to a kind of ball game's site equipment, in particular to a kind of automatic lifting net column. BACKGROUND
[0002] In many ball game sites, a net is needed to be set as necessary equipment for sports, such as badminton, volleyball, tennis, pétanque and so on. These ball games have a common feature that sports are carried out in an area with court lines, and a net is set in the middle of the court to divide the court into two sides. However, not every place has enough space to set different dedicated sports fields to correspond to different ball games. Therefore, many activity venues, such as schools or some local community activity centers or health centers, overlap different ball game fields to effectively use the area of the same field. In other words, different court lines for ball games are drawn on the same floor area, and different ball games can be played on the same field by adjusting the height of the middle net. In this way, different ball games can be effectively played on the same field without increasing the land area.
[0003] However, it is very troublesome to manually measure and adjust the height of each field net every time a different ball game is played, especially when multiple fields need to be adjusted at the same time. For example, manually measuring and adjusting the height of each field net to change a tennis court into a badminton court is very inefficient. SUMMARY
[0004] The main purpose of the utility model is to provide an automatic lifting net column that can quickly and easily adjust the height of the net in a ball game field.

[0008] A housing is arranged on the base, and a reduction gear set is arranged in the housing. The reduction gear set has a transmission shaft protruding out of the housing. A gear is arranged on the transmission shaft, and the gear is engaged with the toothed row on the long rod. A motor is arranged on one side of the housing and connected with the reduction gear set. The motor can drive the reduction gear set to operate and drive the transmission shaft to rotate. The transmission shaft can drive the long rod to move up and down along the sleeve through the gear and the toothed row.
[0009] A control circuit board is arranged in the housing and electrically connected with the sensor and the motor. The control circuit board can control the rotation of the motor, and the signal of the sensor can be transmitted to the control circuit board. The control circuit board is also provided with a signal transmitter and a signal receiver.
[0010] The remote controller is provided with an MCU, a control interface, a signal transmitter and a signal receiver.
[0011] The remote controller can send an opening signal and a starting signal.

Secondly, in the embodiments to be introduced below and the drawings, the same element number represents the same or similar element or its structural feature. The up, down, left and right directions in the text are based on the directions of the drawings for explanation but are not limited.
[0045] Please refer to Figures 1-7The automatic lifting net column is used in the site of the ball game, and two net columns are arranged in each site, that is, two net columns are arranged in a two-one group, and a net stopping device is arranged between the two net columns. The automatic lifting net column comprises:
[0046] A base 10 is long and is vertically arranged on the site of the ball court. The base is provided with a sleeve 11 arranged along the long axis of the base 10. The sleeve 11 is provided with a plurality of notches 12, and the heights of the notches 12 from the ground are different. Each notch 12 is provided with a sensor 13. In the embodiment, the sensor 13 is a micro switch, but is not limited thereto. Other types of sensors, such as infrared sensors, pressure sensors, or magnetic sensors, can also be used.
[0047] A long rod 20 is arranged in the sleeve 11 of the base 10. The long rod 20 is provided with a roller 21 at one end for the hanging rope of the net stopping device. The long rod 20 is provided with a gear rack 22 along the long axis of the long rod 20.
[0048] A housing 30 is arranged on the base 10. The housing 30 is provided with a reduction gear set 31. The reduction gear set 31 is provided with a transmission shaft 32 protruding out of the housing 30. The transmission shaft 32 is provided with a gear 33. The gear 33 is engaged with the gear rack 22 of the long rod 20. The housing 30 is provided with a motor 34 connected with the reduction gear set 31. The motor 34 drives the reduction gear set 31 to rotate the transmission shaft 32. The transmission shaft 32 drives the long rod 20 to move up and down along the sleeve 11 through the gear 33 and the gear rack 22.
[0049] A control circuit board 40 is arranged in the housing 30 and is electrically connected with the sensors 13 and the motor 34. The control circuit board 40 controls the rotation of the motor 34. The signals of the sensors 13 are transmitted to the control circuit board 40. The control circuit board 40 is provided with a signal transmitter 41 and a signal receiver 42.
[0050] A remote controller 50 is provided with an MCU (micro control unit) 51, a control interface 52, a signal transmitter 53, and a signal receiver 54.
[0051] By the above structure, the automatic lifting net post of the utility model is same as general net post in installation, is set in two sides of the court, two automatic lifting net posts are erected between the net, so that the court can be divided into two sides by the net. The utility model is operated by the remote controller 50 to send an opening signal to the two net posts, the two net posts receive the opening signal through the signal receiver 42 of the control circuit board 40, then the two net posts will reply an answer signal to the remote controller 50 respectively, when the remote controller 50 receives the answer signal of the two net posts, the remote controller 50 will send a starting signal to the two net posts, when the two net posts receive the starting signal, the motor 34 will rotate the transmission shaft 32 to drive the long rod 20 to adjust the lifting, so that the two long rods 20 can be lifted or lowered to the set position, and the sensor 13 arranged on the sleeve 11 will send a stop signal to the control circuit board 40 when the long rod 20 is lifted or lowered to the specified position, and the control circuit board will stop the operation of the motor 34.
[0052] The reason why the remote controller needs to send a starting signal to start the lifting action after receiving the answer signal of the two net posts in the utility model is that if only one net post sends an answer signal and the other does not send an answer signal, the net post without sending an answer signal may have faults or no power and cannot work, at this time, if the motor is started to adjust the lifting, one side moves and the other side does not move, so the net may be torn off, therefore, to avoid this situation, the remote controller of the utility model sends a starting signal after receiving the answer signal of the two net posts.
[0053] In this way, the user can quickly and correctly adjust the net to the desired height position, and manual adjustment is no longer needed, and the height of the net required by different ball games can be set by the program in advance, and the operator can complete the operation by one key through the remote controller.
[0054] Of course, the utility model can also have other various embodiments, and those skilled in the art can make various corresponding changes and modifications according to the utility model without departing from the spirit and essence of the utility model, but these corresponding changes and modifications should belong to the protection scope of the utility model claim.
