Detailed description of the invention
Referring to Fig. 1, this utility model is that a kind of physical culture is imparted knowledge to students jumping stand, it include cross bar 1, base 2, column 3 with
And fixing device 4；Column 3 is fixing with base 2 to be connected.
Fixing device 4 includes supporting platform 41, cylinder 42, bolt 43, fixing nahlock 44, rotating nahlock 45, handle 46, nut
47。
Support platform 41 is fixing with cylinder 42 to be connected；Cylinder 42 is made for elastomeric material, such as makes for spring steel；Cylinder
42 cylindrical shapes being generally provided with opening；The two ends of the opening of cylinder 42 are fixedly installed dististyle respectively；Fixing nahlock 44 with
And rotation nahlock 45 is provided with projection and groove；Fix the projection of nahlock 44 and the projection of rotation nahlock 45 just to (the most solid
The protruding centrage determining nahlock 44 overlaps with the protruding centrage rotating nahlock 45)；Fixing nahlock 44 and the one of cylinder 42
Individual dististyle (i.e. near the dististyle rotating nahlock 45) is fixing to be connected；Rotation nahlock 45 is fixing with handle 46 to be connected；Bolt 43 is successively
Run through two pieces of dististyles of cylinder 42, fixing nahlock 44, rotate nahlock 45 and handle 46 and threaded with nut 47.
Cylinder 42 is enclosed within column 3；Cross bar 1 is placed on support platform 41.
The operation principle of a kind of physical culture teaching jumping stand in this utility model is: need to regulate the height of high jump (i.e.
The height of cross bar 1) time, rotating handles 46, handle 46 is rotated nahlock 45 and rotates, and makes the projection of rotation nahlock 45 from fixing circle
The projection of block 44 slides to the groove of fixing nahlock 44, until the projection of fixing nahlock 44 is completely into the groove of rotation nahlock 45,
Fixing nahlock 44 and the distance rotated between nahlock 45 reduce and make bolt 43 to move right, another dististyle of cylinder 42
(i.e. away from the dististyle rotating nahlock 45) is not bolted 43 and supports and away from rotational circle under the effect of the elastic force of cylinder 42 self
Block 45, makes the internal diameter of cylinder 42 become big, and cylinder 42 does not contact column 3 or slight squeeze column 3, so that fixing device 4 is permissible
(i.e. releasing orientation) is slided up and down along column 3.
After fixing device 4 slides up and down along column 3 and is adjusted to desired position, rotating handles 46, handle 46 drives rotation
Turn nahlock 45 to rotate, make the projection of rotation nahlock 45 slide to the projection of fixing nahlock 44 from the groove of fixing nahlock 44, until solid
The projection determining nahlock 44 and the projection rotating nahlock 45 are just to (i.e. fixing protruding centrage and the rotation nahlock 45 of nahlock 44
Protruding centrage overlaps), make fixing nahlock 44 and the distance rotated between nahlock 45 increase and drive bolt 43 to be moved to the left,
Another dististyle (i.e. away from the dististyle rotating nahlock 45) of cylinder 42 is the close nahlock 45 that rotates due to the drive of bolt 43, makes
The internal diameter of cylinder 42 diminishes, and cylinder 42 extrudes column 3, is frictionally held in along column 3 (i.e. so that fixing device 4 relies on
Locking state)；Supporting on platform 41 after placement cross bar 1, the desired height that the height (i.e. the height of cross bar 1) of high jump is adjusted to.
Above-mentioned it can be seen that in this utility model a kind of physical culture teaching jumping stand, the height of high jump can be regulated easily and efficiently
(i.e. the height of cross bar 1).
The inwall of cylinder 42 is also provided with rubber blanket (accompanying drawing is not drawn into).Frictional force can be increased further, make solid
Determine device 4 can more firmly be locked on column 3.
It is also provided with scale on column 3.The height of high jump can be read easily (i.e. according to the scale on column 3
The height of cross bar 1).
Cross bar 1 can be that fiberglass is made.Cross bar 1 can bend, such that it is able to improve safety further.
In sum, a kind of physical culture teaching jumping stand in this utility model, high jump can be regulated easily and efficiently
Highly；The height of high jump can be read easily according to the scale on column 3.
