Description

Technical Field

[0001] The utility model relates to the technical field of sports basketball, and more specifically to a basketball foul timeout and substitution indicator. Background Art

[0002] Basketball substitution signs are often used in sports basketball. Basketball substitution signs are used to convey substitution instructions to players and coaches, helping the team to make effective personnel adjustments and replacements during the game. When players are tired, injured, or need to adjust tactics on the court, coaches can use substitution signs to indicate which players need to enter or leave the court to keep the team in the best condition.

[0003] At present, the basketball foul timeout substitution sign in the prior art is usually an integral whole, which is not convenient to shrink or disassemble. When the device is moved, the device needs to be moved as a whole. Since the device is relatively high as a whole, it will take up a large space when stored after use, and it is easy to be touched and tipped over. In addition, the display screen on the existing device is generally not easy to disassemble. When the device is not in use, dust will accumulate on the surface of the display screen, which will affect the effect of the next use to a certain extent. In addition, when the device is moved and stored, the display screen may collide with other objects, which may cause damage to the display screen. Therefore, there is an urgent need for a basketball foul timeout substitution sign to solve the above problems. Utility Model Content

[0004] In order to overcome the above defects of the prior art, the utility model provides a basketball foul timeout substitution indicator to solve the problems existing in the above background technology.

[0005] The utility model provides the following technical solution: a basketball foul timeout substitution indicator, comprising:

[0006] A telescopic structure, the telescopic structure comprising a base, a clamping structure installed inside one side of the telescopic structure, and the telescopic structure is used for contraction of the device;

[0007] A snap-fit ​​structure, wherein the snap-fit ​​structure comprises a fixing plate and a snap-fit ​​block, and one end of the fixing plate is fixedly connected to the outer surface of one side of the telescopic structure, and the snap-fit ​​structure is used to fix the retracted state of the device;

[0033] Working principle: When the device is in use, the base 11 is used to place the device in a suitable position, and the telescopic rod 13 inserted inside the support rod 12 is lifted upward, so that the positions of the engaging grooves opened on the surfaces of one side of the support rod 12 and the telescopic rod 13 correspond to each other. The spring 24 uses its own elastic force to push the engaging block 23 to rotate along the fixed column 22, so that the other end of the engaging block 23 is engaged with the inside of the engaging grooves opened on the surfaces of one side of the support rod 12 and the telescopic rod 13. The upper surface of one end of the engaging block 23 is against the lower surface of the other end of the spring 24, preventing the telescopic rod 13 from moving downward. At this time, the telescopic structure 1 is in use;

[0034] Lift the main structure 3 through the handles on both sides of the outer frame 31, snap the clamping plate 33 onto the outer surface of the telescopic rod 13, pull the upper end of the pull rod 36 to rotate one end of the pull rod 36 along the support seat 35, and drive the hinge plate 37 to hinge and rotate, and at the same time drive the latch 38 to move inside the support seat 39, align the latch 38 with the slot 14 and the circular hole on one side of the clamping plate 33, lower the pull rod 36 to move the hinge plate 37, and push the latch 38 to insert into the slot 14 and the inside of the clamping plate 33, and fix the main structure 3 to the base 11. When the device is in use, the LED display screen 32 is powered by the battery inside the outer frame 31, so as to display the information of changing people;

[0035] After use, the pull rod 36 is pulled to disengage the latch 38 from the slot 14 and the circular hole on one side of the engaging plate 33, so that the main structure 3 and the telescopic rod 13 are no longer engaged. Then the staff puts the main structure 3 into a closable storage box.

[0036] Then press the surface of one end of the locking block 23 to make the locking block 23 rotate, and at the same time, the other end of the locking block 23 is separated from the inside of the support rod 12 and the telescopic rod 13, and the telescopic rod 13 is inserted downward into the inside of the support rod 12, so that the telescopic structure 1 is turned into the storage state. At this time, the staff will store the telescopic structure 1 and the main structure 3 respectively. The above is the entire working principle of the utility model.
