Description

Overhead type backstroke is set out device and its application method

Technical field

The technical field of the special equipment used when being set out the present invention relates to backstroke, more particularly to a kind of overhead type backstroke Set out device and its application method.

Background technology

Backstroke set out device be used for swim backstroke project competition and training, be backstroker uses when backstroking and setting out Special equipment.The overhead type backstroke device that sets out is mounted in the swimming top of starting block or setting installed in the top for the determining device that sets out It is standby.According to international swimming union and Chinese Swimming Association《The rules of contest of swimming 2014-2018》Regulation, backstroke sets out the upper of device pedal It is that backstroke is set out the zero-bit of device that end face is concordant with the water surface of swimming pool；The set out pedal of device of backstroke can adjust 4CM on the water surface To the 4CM of underwater.Backstroke sets out device installed in starting block top, thus occurs in that two problems：1）The water of each swimming pool The height on identity distance ground all can be variant；2）The height of the starting block of each swimming pool institute adapted also differ it is identical because of the age, hold Caused by the factors such as rower standard, manufacturer）；Because of above-mentioned reason, when device is set out in the installation backstroke of each venue, it is necessary to first adjust zero Position.Gear refer to backstroke set out device pedal upper surface it is concordant with the water surface of swimming pool be zero-bit, the backstroke device that sets out should be shown as 0, It is+1 to rise 1CM from the water surface, and it is -1 to decline 1CM from the water surface.It is -4 to decline 4CM from the water surface.

For the device that sets out of backstroking, the country there has been pertinent literature report, and such as Publication No. CN303108511S China is outer See patent backstroke to set out device, innovative design has only been carried out in terms of outward appearance, has not been designed newly from configuration aspects, and use Inconvenience.Now in the world, the only Italian design of A ＆ T Europe S.p.A joint-stock companies and manufacture backstroke is set out device, mesh It is preceding within Chinese territory also do not design and produce backstroke set out device company and unit.

The backstroke used in the world set out device be exactly A ＆ T Europe S.p.A joint-stock companies design and manufacture backstroke Set out device.Prior art has the following disadvantages：

1）Zero-bit regulation is inconvenient：The set out zero-bit of device of backstroke refers to backstroke the water surface of device pedal upper surface and swimming pool of setting out Relativeness；The set out zeroing of device of existing backstroke is that respectively have two holding screws on the belt wheel of left and right, and left and right belt wheel is distinguished It is fixed on rotating shaft steel pipe）On two ends, when adjusting zero-bit, the holding screw on the belt wheel of left and right is unclamped respectively, left belt wheel and the right side Belt wheel is adjusted respectively, is inconvenient；Because left and right belt wheel is adjusted respectively, the length for also easily causing left and right load-bearing band is inconsistent, makes Into setting out, pedal is tilted；Again because belt wheel is high polymer material, often regulation holding screw can cause the screw of high polymer material to grind Damage, belt wheel fixes the risk with failure, certain hidden danger is brought to backstroke race.

2）Gear regulation is not directly perceived：It is existing backstroke set out device gear regulation display be：4、2、0、-2、-4.In regulation Middle shortage gear numeral 3,1, -1, -3, it is less directly perceived when actual use, it is necessary to operator makes reasoning, it is sometimes prone to behaviour Slip up；

3）Insecure, manufacturability is installed poor：The existing backstroke device that sets out is installed on starting block or is mounted to the determining device that sets out On, it is required for processing the wide 8mmX depths 22mm of long 58mmX two parallel elongated holes on mounting plane, manufacturability is poor, no Beneficial to the cooperation and transformation of existing swimming place and hall starting block, live bad adaptability, processing technology is poor, constructs inconvenient, Also it is not easy to ensure dimensional accuracy；Two strip projections are arranged at the set out bottom of device of backstroke, are distributed in the left and right sides, are inserted during installation Enter in two elongated holes processed on mounting plane, play a part of fixed backstroke and set out device, but the backstroke device that sets out has after installing Loosen phenomenon；Because both feet generation instantaneous impact is very big when sportsman sets out again, a certain degree of loosening is had in use existing As；

4）Pedal skid resistance of setting out is bad：Existing backstroke is set out the pedal that sets out of device, and it is raised that non-skid feature uses column type Dot matrix, because column type height of projection only has 1mm, and the raised spacing of column type is larger, when the sole of sportsman sets foot on the pedal When, the insertion degree deformed to sole skin is relatively low, and skidproof effect is poor, so non-skid property is bad in water；

5）Unsafe storage, inconvenience：It is existing backstroke set out device carrying belt be all wound on belt wheel after, that is, the pedal that sets out receive After rising, the unfixed pedal that sets out, the pedal that makes to set out, which is in, naturally droops state.Whenever setting out after device picking up backstroke, it goes out Hair pedal just dangles, dangerous to be also inconvenient to pack；The set out packaging of device of existing backstroke uses fiber in transport The soft-body packaging bag that cloth is made, every bag is placed a device that sets out of backstroking, and is not easy to prevent mutually collision and accumulating.

It is therefore desirable to newly propose that a kind of backstroke of overhead type is set out device and its application method.
